Aquatic ecosystems are currently experiencing unprecedented levels of impact from human activities including over-exploitation of resources, habitat destruction, pollution and the influence of climate change. The impacts of these activities on the microbial ecology of aquatic environments are only now beginning to be defined. One of the many implications of environmental degradation and climate change is the geographical expansion of disease- causing microbes such as those from the Vibrio genus. Elevating sea surface temperatures correlate with increasing Vibrio numbers and disease in marine animals (e.g. corals) and humans. Contamination of aquatic environments with heavy metals and other p...
Antibiotics and antibiotic resistance have most commonly been viewed in the context of human use and effects. However, both have co-existed in nature for millennia. Recently the roles of antibiotics and antibiotic resistance genes have started to be discussed in terms of functions other than bacterial inhibition and protection. This special topic will focus on both the traditional role of antibiotics as warfare mechanisms and their alternative roles and uses within nature such as antibiotics as signals or communication mechanisms, antibiotic selection at low concentrations, the non-specific role of resistance mechanisms in nature: e.g. efflux pumps, evolution of antibiotic resistance and the role of persisters in natural antibiotic resistance.
This book offers comprehensive coverage of all manifestations of resistance in combating infectious diseases and explores advances in antimicrobial resistance in agriculture and their applications in the fight against microbes. It discusses and compares biological, biochemical, and structural aspects of resistance and its evolution. This is a comprehensive tool covering all manifestations of antimicrobial resistance and microbial resistance genes. In addition, it also provides a variety of photographs, diagrams, and tables to help illustrate the material. Novel strategies to combat antimicrobial resistance are also described, emphasizing collaborative measures of control. The underlining mol...
This book illuminates what engineering is and how it relates to other disciplines such as art, architecture, law, economics, science, technology, and even religion. The author explains, from an intrinsic as well as descriptive perspective, why engineering is essential for our collective well-being, and how, like medicine, it is undertaken by people, and for people, to improve the human condition. He brings out the 'magic' of engineering practice as well as addressing the darker aspects such as warfare and the misuse of the internet. A too commonly held view assumes that the practice of engineers is a cold, purely quantitative and wholly technical enterprise of applying know science, and devo...
Discussion of bioscience ethics requires understanding of the science that underpins biological systems impinging on our lives. Unencumbered by the formal structure of ethics, bioethics presents a forum for discussion of practical matters of individual and collective concern. This comprehensive text is a guide to the essentials of bioscience ethics and an interface between applied science and applied bioethics. Early chapters embrace topics affecting human reproduction – substance abuse and parenthood, aging gametes and congenital malformations, child abuse and its biological consequences. Intermediate chapters deal with end-of-life care and euthanasia, human fertility, assisted reproductive technologies, genetic engineering, and cloning. Remaining chapters challenge human-dominated ecosystems. Population growth, economic activity, and warfare – with its environmental consequences – are reviewed. A background section describes the evolution of ethical consciousness, explores the future, and proposes that the reworking of ethical boundaries can enhance mature decision-making in harmony with changing technology.
This book is a collection of studies about forms of address in the world’s languages, with a focus on contrast and difference. The individual chapters highlight inter- and intralinguistic variation in the expression of address and its sociol-cultural functions across media, registers, geographical contexts and time – in more than 15 languages. The volume showcases the variety of approaches that exists in current address research, including the breadth of contrastive methodologies harnessing surveys and questionnaires, focus group discussions, corpus linguistics, discourse and conversation analysis to offer complementary perspectives on culture-specific address practice. This volume is for students and researchers of address and social interaction in a range of disciplines in the humanities and social sciences, including various sub-disciplines of linguistics (such as contrastive, variational and intercultural pragmatics, sociolinguistics, and morphology) and intercultural communication, as well as experts in individual languages and qualitative sociologists.
A detailed, research-informed synthesis of the current issues facing the Australasian biota and the challenges involved in their conservation.
A history of the unsustainable modern diet—heavy in meat, wheat, and sugar—that requires more land and resources than the planet is able to support. We are facing a world food crisis of unparalleled proportions. Our reliance on unsustainable dietary choices and agricultural systems is causing problems both for human health and the health of our planet. Solutions from lab-grown food to vegan diets to strictly local food consumption are often discussed, but a central question remains: how did we get to this point? In Diet for a Large Planet, Chris Otter goes back to the late eighteenth century in Britain, where the diet heavy in meat, wheat, and sugar was developing. As Britain underwent s...
