Explaining Reproduction

Discusses the male and female reproductive systems, explaining how they work together to form new life, and describing the stages of pregnancy and childbirth.

Crystallizing the essential principles of social reproductive theory, this anthology provides long-overdue analysis of everyday life under capitalism. It focuses on issues such as childcare, healthcare, education, family life, and the roles of gender, race, and sexuality--all of which are central to understanding the relationship between exploitation and social oppression. Tithi Bhattacharya brings together some of the leading writers and theorists, including Lise Vogel, Nancy Fraser, and Susan Ferguson, in order for us to better understand social relations and how to improve them in the fight against structural oppression.

Featuring examples from all kinds of living organisms, this book offers a fresh view on sex and reproduction.

Discusses the male and female reproductive systems, explaining how they work together to form new life, describing diseases that affect the system, and examining ethical debates from birth control to infertility.

Our understanding of reproduction and reproductive processes is often biased towards the behaviour of organisms most familiar to us. As such, the amazing disparity of the phenomena of reproduction and sex is often overlooked. Understanding Reproduction addresses all the main facets of this large chapter of the life sciences, including discussions of asexual reproduction, parthenogenesis, sex determination, reproductive effort, and much more. The book features an abundance of examples from across the tree of life, including animals, plants, fungi, protists and bacteria. Written in an accessible and easy to digest style, overcoming the intimidating diversity of the technical terminology, this book will appeal to interested general readers, biologists, science educators, philosophers and medical doctors.

Sub-Saharan Africa is considered the last region in the world where women still give birth to presumably too many children. However, within large cities such as Maputo, the capital of Mozambique, the average number of children per woman varies greatly. What is extraordinary, as this book shows, is that childbearing is a social action. Parenting allows one to consider different action alternatives, or rather, opportunities to act. These actions are not the same for everyone in different contexts. The book highlights that macro level socio- demographic changes, namely intraurban reproductive disparities are brought up by micro level (individual) actions.

Some investigators have hypothesized that estrogens and other hormonally active agents found in the environment might be involved in breast cancer increases and sperm count declines in humans as well as deformities and reproductive problems seen in wildlife. This book looks in detail at the science behind the ominous prospect of "estrogen mimics" threatening health and well-being, from the level of ecosystems and populations to individual people and animals. The committee identifies research needs and offers specific recommendations to decision-makers. This authoritative volume: Critically evaluates the literature on hormonally active agents in the environment and identifies known and suspected toxicologic mechanisms and effects of fish, wildlife, and humans. Examines whether and how exposure to hormonally active agents occursâ€"in diet, in pharmaceuticals, from industrial releases into the environmentâ€"and why the debate centers on estrogens. Identifies significant uncertainties, limitations of knowledge, and weaknesses in the scientific literature. The book presents a wealth of information and investigates a wide range of examples across the spectrum of life that might be related to these agents.

One of the pathways by which the scientific community confirms the validity of a new scientific discovery is by repeating the research that produced it. When a scientific effort fails to independently confirm the computations or results of a previous study, some fear that it may be a symptom of a lack of rigor in science, while others argue that such an observed inconsistency can be an important precursor to new discovery. Concerns about reproducibility and replicability have been expressed in both scientific and popular media. As these concerns came to light, Congress requested that the National Academies of Sciences, Engineering, and Medicine conduct a study to assess the extent of issues related to reproducibility and replicability and to offer recommendations for improving rigor and transparency in scientific research. Reproducibility and Replicability in Science defines reproducibility and replicability and examines the factors that may lead to non-reproducibility and non-replicability in research. Unlike the typical expectation of reproducibility between two computations, expectations about replicability are more nuanced, and in some cases a lack of replicability can aid the process of scientific discovery. This report provides recommendations to researchers, academic institutions, journals, and funders on steps they can take to improve reproducibility and replicability in science.
