Background: The purpose of this qualitative, phenomenological study was to explore the subjective experiences of infertile women who conceived through the use of assisted reproduction technology-ovarian stimulation, intrauterine insemination or IVF-only to lose their pregnancy at 2-16 weeks gestation. Methods: Ten women participated in in-depth, tape-recorded interviews. After initial content analysis, a phenomenological analysis was undertaken to identify common themes in the participants' stories. Results: Nine common themes were identified. These included: a sense of profound loss and grief; diminished control; a sense of shared loss with their partners; injustice or lack of fairness; ongoing reminders of the loss; social awkwardness; fear of re-investing in the treatment process or a subsequent pregnancy; the need to make sense of their experience; and feelings of personal responsibility for what had happened. Conclusion: SParticipants' experiences of pregnancy loss were embedded within their experiences of infertility and medical treatment, and shaped by their significant investment in having a child. A significant feature was their marked ambivalence regarding future reproductive options after their pregnancy loss, reflecting a unique overlay of prominent anxiety in their grief experience.

An International Union of Geological Sciences working group is expected to soon formalize a determination that we have moved from the Holocene to the Anthropocene Epoch on the geologic time scale. In addition to reaching consensus on the scientific evidence for this change, this initiative is meant to raise awareness in other scientific communities of the effects of large-scale human activity on fundamental earth system parameters. In parallel, work is being done to understand the resiliency of our planet to the large human footprint, and to define and quantify the planetary boundaries that define a safe operating space for humanity. Many of these planetary boundaries are quantified by chemical measurements. We explore the implications of these parallel developments for chemistry educators. © 2014 The American Chemical Society and Division of Chemical Education, Inc.

Although religions are major social actors and institutions with considerable reach, relatively little social science research has focused specifically on the interaction of religious bodies and human-induced climate change. Most of the current scholarship on the topic has been theological, pastoral, or normative, and specific to particular faiths; the focus of such scholarship is to draw on resources internal to the faith in order to make the case to adherents about the duty to attend to climate change. Only recently has empirical or social scientific research sought to examine what the world's religions and their adherents are actually saying or doing about climate change. Reviewing this research is the focus of this article. An essential first step is to conceptualize the problematic term 'religion' and to describe the extensive diversity of the world's religions. Religion includes beliefs, worldviews, practices, and institutions that cross borders, time, and scale from the level of individuals all the way to transnational and transhistorical movements. A summary of religious engagements with climate change is followed by two case studies that show the complexity of religion and religious engagement with climate change. The Pacific Islands are used as a geographic case. Buddhism is used as a case study of a specific faith tradition. Because the world's religions and faith groups are major social institutions and sites of collection action, greater attention to them by climate-oriented social scientists is recommended. © 2014 John Wiley & Sons, Ltd.

Reserves of natural gas in Bangladesh are very large and total demand has increased secularly in recent years. This paper examines the causal relationship between the consumption of natural gas and GDP in Bangladesh over the period 1980 to 2010. We find that there is a positive unidirectional causality running from GDP to natural gas consumption: movements in GDP affect the consumption of natural gas but not vice-versa. While our results rest on several statistical assumptions, they support the pursuit of policies that are in line with energy conservation. Implementing these policies will be of particular significance in light of the fact that Bangladesh's current reserves of natural gas will not meet its current level of consumption demand beyond the next two decades. © 2013 Elsevier Ltd.

Although Random Testing (RT) is low cost and straightforward, its effectiveness is not satisfactory. To increase the effectiveness of RT, researchers have developed Adaptive Random Testing (ART) and Quasi-Random Testing (QRT) methods which attempt to maximize the test case coverage of the input domain. This paper proposes the use of Centroidal Voronoi Tessellations (CVT) to address this problem. Accordingly, a test case generation method, namely, Random Border CVT (RBCVT), is proposed which can enhance the previous RT methods to improve their coverage of the input space. The generated test cases by the other methods act as the input to the RBCVT algorithm and the output is an improved set of test cases. Therefore, RBCVT is not an independent method and is considered as an add-on to the previous methods. An extensive simulation study and a mutant-based software testing investigation have been performed to demonstrate the effectiveness of RBCVT against the ART and QRT methods. Results from the experimental frameworks demonstrate that RBCVT outperforms previous methods. In addition, a novel search algorithm has been incorporated into RBCVT reducing the order of computational complexity of the new approach. To further analyze the RBCVT method, randomness analysis was undertaken demonstrating that RBCVT has the same characteristics as ART methods in this regard. © 1976-2012 IEEE.
