Digit Ratio by John T. Manning Pdf

Manning (biological sciences, University of Liverpool) argues that the relative lengths of the second and fourth fingers are genetically linked to hormone- and sex-related traits, and by extension with sperm counts, family size, musical genius, sporting prowess, autism, depression, homosexuality, heart problems, and breast cancer. He suggests that the study of the ratio between the lengths of the second and fourth finger can broaden our understanding of human ability, behavior, and health. Three photographs, 38 figures, and eight tables are included. Annotation copyrighted by Book News Inc., Portland, OR.

Digit Ratio by John T. Manning Pdf

Could the length of your fingers indicate a predisposition to breast cancer? Or musical genius? Or homosexuality? In Digit Ratio, John T. Manning posits that relative lengths of the second and fourth digits in humans (2D:4D ratio) does provide such a window into hormone- and sex-related traits. It has been known for more than a century that men and women tend to differ in the relative lengths of their index (2D) and ring (4D) fingers, which upon casual observation seem fairly symmetrical. Men on average have fourth digits longer than their second digits, while women typically have the opposite. Digit ratios are unique in that they are fixed before birth, while other sexually dimorphic variables are fixed after puberty, and the same genes that control for finger length also control the development of the sex organs. The 2D:4D ratio is the only prenatal sexually dimorphic trait that measurably explains conditions linking testosterone, estrogen, and human development; the study of the ratio broadens our view of human ability, talent, behavior, disposition, health, and fertility. In this book, Manning presents evidence for how 2D:4D correlates with traits ranging from sperm counts, family size, musical genius, and sporting prowess, to autism, depression, homosexuality, heart attacks, and breast cancer, traits that are all linked with early exposure to sex hormones.

Berry-AMA Book Prize FINALIST 2011! “The Right Sensory Mix” is one of the four best marketing books in 2011 according to the American Marketing Association Foundation. The Berry-AMA Book Prize is awarded annually be the Foundation (AMAF) and recognizes books whose innovative ideas have had significant impact on marketing and related fields. For additional information about the Berry-AMA Book Prize, visit Berry-AMA Book Prize. Why do some people drink black coffee and others stick to tea? Why do some people prefer competitors’ products? Why do we sell less in this country? Many companies fail to acknowledge and analyze disparities observed among customers and simply put them down to culture or emotion. New neuroendocrinological research proves that consumers are rational: They just have a different biological perception of the same stimulus! Their preferences, behavior, and decisions are strongly influenced by the hundreds of millions of sensors monitoring their body and brain. People with more taste buds are for example sensitive to bitterness and are more likely to drink their coffee with sugar or milk, or to drink tea. After reading the book, managers will be able to: • Understand and predict consumers’ behavior and preferences • Design the right sensory mix (color, shape, taste, smell, texture, and sound) for each product • Fine-tune their positioning and product range for every local market • Systematically increase their innovation hit rate

Animal Homosexuality by Aldo Poiani Pdf

Homosexuality is an evolutionary paradox in search for a resolution, not a medical condition in search for a cure. Homosexual behavior is common among social animals, and mainly expressed within the context of a bisexual sexual orientation. Exclusive homosexuality is less common, but not unique to humans. Poiani and Dixson invite the reader to embark on a journey through the evolutionary, biological, psychological and sociological aspects of homosexuality, seeking an understanding of both the proximate and evolutionary causes of homosexual behavior and orientation in humans, other mammals and birds. The authors also provide a synthesis of what we know about homosexuality into a biosocial model that links recent advances in reproductive skew theory and various selection mechanisms to produce a comprehensive framework that will be useful for anyone teaching or planning future research in this field.

Mind, Life and Universe by Lynn Margulis,Eduardo Punset Pdf

Nearly forty of the world's most esteemed scientists discuss the big questions that drive their illustrious careers. Co-editor Eduardo Punset—one of Spain's most loved personages for his popularization of the sciences—interviews an impressive collection of characters drawing out the seldom seen personalities of the world's most important men and woman of science. In Mind, Life and Universe they describe in their own words the most important and fascinating aspects of their research. Frank and often irreverent, these interviews will keep even the most casual reader of science books rapt for hours. Can brain science explain feelings of happiness and despair? Is it true that chimpanzees are just like us when it comes to sexual innuendo? Is there any hard evidence that life exists anywhere other than on the Earth? Through Punset's skillful questioning, readers will meet one scientist who is passionate about the genetic control of everything and another who spends her every waking hour making sure African ecosystems stay intact. The men and women assembled here by Lynn Margulis and Eduardo Punset will provide a source of endless interest. In captivating conversations with such science luminaries as Jane Goodall, James E. Lovelock, Oliver Sachs, and E. O. Wilson, Punset reveals a hidden world of intellectual interests, verve, and humor. Science enthusiasts and general readers alike will devour Mind, Life and Universe, breathless and enchanted by its truths.

Provides the most up-to-date information on transgender science and its applications, for gender-diverse people, their supporters, and the professionals who assist them to lead healthy, happy, and successful lives. The number of people presenting at gender clinics worldwide for assistance has increased exponentially in the last decade. Transgender people also have become much more prominent in the media.

The content of this book ranges from theoretical ideas about the origin of gender diversity to practical solutions for trans* people to enjoy life in their chosen gender. Physical health topics include hormone therapy, puberty blockers, breast augmentation/reduction, gender confirmation surgery, and speech therapy. Mental health topics include dealing with discrimination, bullying, and transphobia. The text is presented so that it can be understood with no scientific background, but is also highly relevant to the health professional.

The Ulnar Nerve by Giuliano Gentili,Mario Di Napoli Pdf

This book systematically reviews sensory and motor nerve conduction studies on the ulnar nerve, from pilot human studies of peripheral nerve conduction in the 1950s through to the most recent scientific evidence. Precise descriptions are provided of approx. 70 nerve conduction techniques that were reproduced in the laboratory, with organization of the techniques according to practical criteria for ease of reference. Particular attention is devoted to those techniques that have shown higher sensitivity and specificity in diagnosis of compressive mononeuropathies, such as ulnar neuropathy at the elbow or wrist. Normal and pathological values derived from the original articles and the subsequent literature are presented, and the wealth of illustrative material facilitates comprehension and reproduction of each technique. The volume is completed by a detailed, well-illustrated glossary explaining the more commonly used terms in electrodiagnostic medicine. This book will appeal to novice and experienced neurologists, students, clinical neurophysiology technicians, and rehabilitation physicians. It represents a logical extension of the volumes on the median nerve recently published by Springer.

The Finger Ratio by John Manning Pdf

SCIENCE: GENERAL ISSUES. What could fingers and sex possibly have in common? What does the shape of a child's fingers reveal about future musical talent? And why should professional footballers have longer fingers than other men? This book is about a simple measurement of the human hand: the 'finger ratio', or the length of the ring finger relative to the index finger. John Manning uses a tiny difference between the sexes - that men tend to have a greater finger ratio than women - to examine a dizzying group of questions about human behaviour, from sexuality, to musical ability, to predisposition to disease. Provocative, intriguing and balanced, John Manning's cutting-edge research poses many fruitful and unusual questions about what makes us as we are.
