Book excerpt: While a Vice President at Salesforce, David Priemer had an epiphany during one of the company's high-pressure selling periods: the very sales tactics they were using were not working on him. Yes, the numbers still showed results, but through brute force rather than elegance and efficiency. Priemer also discovered that his sales colleagues were spending far more time on leads that did not convert to sales than on those that did. His company--and his entire profession--was acting with more than enough gusto, but without enough awareness and empathy. They were not selling the way they buy. Sell the Way You Buy is about much more than putting yourself in the customer's shoes. Customers don't always know what they want or need, or they may be seeking a solution for something that isn't their core problem. They suffer from status quo bias, from recency bias, from confirmation bias. And meanwhile, the state of overwhelming choice has most products and solution providers adrift in the "Sea of Sameness." In today's world, almost everyone is in sales, but as Priemer realized, we don't teach it. Sell the Way You Buy will show you how to ask questions, how to listen, how to tell a compelling brand story, and how to talk to customers (how to talk to people). Priemer reveals scientifically supported methods to understand the customer, identify their needs, and move them toward the right solution--all the while teaching you to avoid all the reasons why the average person doesn't like salespeople. In short, to sell the way you buy.

Available in PDF, EPUB and Kindle. Book excerpt: Hallucinatory phenomena have held the fascination of science since the dawn of medicine, and the popular imagination from the beginning of recorded history. Their study has become a critical aspect of our knowledge of the brain, making significant strides in recent years with advances in neuroimaging, and has established common ground among what normally are regarded as disparate fields. The Neuroscience of Hallucinations synthesizes the most up-to-date findings on these intriguing auditory, visual, olfactory, gustatory, and somatosensory experiences, from their molecular origins to their cognitive expression. In recognition of the wide audience for this information among the neuroscientific, medical, and psychology communities, its editors bring a mature evidence base to highly subjective experience. This knowledge is presented in comprehensive detail as leading researchers across the disciplines ground readers in the basics, offer current cognitive, neurobiological, and computational models of hallucinations, analyze the latest neuroimaging technologies, and discuss emerging interventions, including neuromodulation therapies, new antipsychotic drugs, and integrative programs. Among the topics covered: Hallucinations in the healthy individual. A pathophysiology of transdiagnostic hallucinations including computational and connectivity modeling. Molecular mechanisms of hallucinogenic drugs. Structural and functional variations in the hallucinatory brain in schizophrenia. The neurodevelopment of hallucinations. Innovations in brain stimulation techniques and imaging-guided therapy. Psychiatrists, neurologists, neuropsychologists, cognitive neuroscientists, clinical psychologists, and pharmacologists will welcome The Neuroscience of Hallucinations as a vital guide to the current state and promising future of their shared field.

Available in PDF, EPUB and Kindle. Book excerpt: To the uninformed, surveys appear to be an easy type of research to design and conduct, but when students and professionals delve deeper, they encounter the vast complexities that the range and practice of survey methods present. To complicate matters, technology has rapidly affected the way surveys can be conducted; today, surveys are conducted via cell phone, the Internet, email, interactive voice response, and other technology-based modes. Thus, students, researchers, and professionals need both a comprehensive understanding of these complexities and a revised set of tools to meet the challenges. In conjunction with top survey researchers around the world and with Nielsen Media Research serving as the corporate sponsor, the Encyclopedia of Survey Research Methods presents state-of-the-art information and methodological examples from the field of survey research. Although there are other "how-to" guides and references texts on survey research, none is as comprehensive as this Encyclopedia, and none presents the material in such a focused and approachable manner. With more than 600 entries, this resource uses a Total Survey Error perspective that considers all aspects of possible survey error from a cost-benefit standpoint. Key Features Covers all major facets of survey research methodology, from selecting the sample design and the sampling frame, designing and pretesting the questionnaire, data collection, and data coding, to the thorny issues surrounding diminishing response rates, confidentiality, privacy, informed consent and other ethical issues, data weighting, and data analyses Presents a Reader′s Guide to organize entries around themes or specific topics and easily guide users to areas of interest Offers cross-referenced terms, a brief listing of Further Readings, and stable Web site URLs following most entries The Encyclopedia of Survey Research Methods is specifically written to appeal to beginning, intermediate, and advanced students, practitioners, researchers, consultants, and consumers of survey-based information.

Available in PDF, EPUB and Kindle. Book excerpt: Biosafety deals with prevention of large scale loss of biological integrity focusing both on ecology and human health. It is related to several fields such as ecology, agriculture, medicine, chemistry and ecobiology. Bioethics is the philosophical study of the ethical controversies brought about by advances in biology and medicine. It is concerned with the ethical questions that arise in the relationships among life sciences, biotechnology, medicine, politics, law, philosophy and theology. It is concerned with the nature of life and death, the kind of life to be considered worth living, what constitutes murder, how people in very painful circumstances should be treated, what are the responsibilities of one human being to others, and other such living organisms. The book has been divided in 28 chapters. It is an integrated approach to encompassing information on different aspects of bioethics and biosafety and their applications in biotechnology. Simple, clearly understandable illustrations, correct and up to date information's are the main features of this book. The book is intended not only for undergraduate and postgraduate students of biotechnology, genomics and related sciences, but is also aimed to draw attention of policy makers and teachers at national and international levels to the possible approaches in the field of biotechnology. Key Features: Covers the topics in depth from basic and deals with the key subject areas. Takes a broader view of the earlier and current situation indifferent countries. Gives the uses and their ethical aspects of the different technological developments made in the biotechnology fields. Covers new developments in wider areas of biotechnology and its applications to mankind. Deals with aspects of the Bioethics and Biosafety protocols and their implements. Briefs the Indian Biodiversity Act.

Available in PDF, EPUB and Kindle. Book excerpt: Agricultural (or "green") biotechnology is a source of growing tensions in the global trading system, particularly between the United States and the European Union. Genetically modified food faces an uncertain future. The technology behind it might revolutionize food production around the world. Or it might follow the example of nuclear energy, which declined from a symbol of socioeconomic progress to become one of the most unpopular and uneconomical innovations in history. This book provides novel and thought-provoking insights into the fundamental policy issues involved in agricultural biotechnology. Thomas Bernauer explains global regulatory polarization and trade conflict in this area. He then evaluates cooperative and unilateral policy tools for coping with trade tensions. Arguing that the tools used thus far have been and will continue to be ineffective, he concludes that the risk of a full-blown trade conflict is high and may lead to reduced investment and the decline of the technology. Bernauer concludes with suggestions for policy reforms to halt this trajectory--recommendations that strike a sensible balance between public-safety concerns and private economic freedom--so that food biotechnology is given a fair chance to prove its environmental, health, humanitarian, and economic benefits. This book will equip companies, farmers, regulators, NGOs, academics, students, and the interested public--including both advocates and critics of green biotechnology--with a deeper understanding of the political, economic, and societal factors shaping the future of one of the most revolutionary technologies of our times.

Available in PDF, EPUB and Kindle. Book excerpt: Social Sensing and Big Data Computing for Disaster Management captures recent advancements in leveraging social sensing and big data computing for supporting disaster management. Specifically, analysed within this book are some of the promises and pitfalls of social sensing data for disaster relevant information extraction, impact area assessment, population mapping, occurrence patterns, geographical disparities in social media use, and inclusion in larger decision support systems. Traditional data collection methods such as remote sensing and field surveying often fail to offer timely information during or immediately following disaster events. Social sensing enables all citizens to become part of a large sensor network which is low cost, more comprehensive, and always broadcasting situational awareness information. However, data collected with social sensing is often massive, heterogeneous, noisy, and unreliable in some aspects. It comes in continuous streams, and often lacks geospatial reference information. Together, these issues represent a grand challenge toward fully leveraging social sensing for emergency management decision making under extreme duress. Meanwhile, big data computing methods and technologies such as high-performance computing, deep learning, and multi-source data fusion become critical components of using social sensing to understand the impact of and response to the disaster events in a timely fashion. This book was originally published as a special issue of the International Journal of Digital Earth.

Book excerpt: This highly successful reader presents the interactionist approach to the study of deviance, examining deviance as a phenomenon that is constituted through social interpretations and the reactions of persons caught up in this social process. This book focuses on issues such as how individuals interpret and label people, how people relate to one another based on these interpretations, and the consequences of these social processes. This perspective helps students understand both social process in general and the sociology of deviance in particular.

Available in PDF, EPUB and Kindle. Book excerpt: Humans are plagued by shortsighted thinking, preferring to put off work on complex, deep-seated, or difficult problems in favor of quick-fix solutions to immediate needs. When short-term thinking is applied to economic development, especially in fragile nations, the results—corruption, waste, and faulty planning—are often disastrous. In Bringing in the Future, William Ascher draws on the latest research from psychology, economics, institutional design, and legal theory to suggest strategies to overcome powerful obstacles to long-term planning in developing countries. Drawing on cases from Africa, Asia, and Latin America, Ascher applies strategies such as the creation and scheduling of tangible and intangible rewards, cognitive exercises to increase the understanding of longer-term consequences, self-restraint mechanisms to protect long-term commitments and enhance credibility, and restructuring policy-making processes to permit greater influence of long-term considerations. Featuring theoretically informed research findings and sound policy examples, this volume will assist policy makers, activists, and scholars seeking to understand how the vagaries of human behavior affect international development.

Book excerpt: Interest in the impact of ethical systems and social or religious ideologies on socio-behavioral patterns is a longstanding theme in social science research. While interest may have begun with Max Weber and his thesis of the relationship between the Protestant ethic and the spirit of capitalism, it extends far beyond this. Surprisingly, few studies have delved into the socio-behavioral patterns emanating from Jewish ethics. This book, with a new introduction by the author, fills that gap.As Hasidic Psychology makes clear, Jewish ethics are unique in many ways, especially in that they are essentially other-centered. Man's ability to affect his own future and interpersonal relations are explained according to the theory of contraction, popularized in Hasidic thought: God, by contracting Himself to evacuate space for the human world, bestowed upon man the power and responsibility to determine his own future, and even affect God's disposition.In the first part of the book, the sociological-structural concept of mono versus multiple ideal labeling is introduced. This concept refers to a social system in which diverse material and spiritual actualization patterns are structurally introduced as equal social ideals. In the second part, basic tenets of classic interaction and socialization are compared to the interpersonal perspective, and the contraction theory is explained as a process of "mutual emulation," whereby father and son affect each other. In the third part, a functional approach to deviance is developed through the Hasidic process known as "ascend via descend."

Available in PDF, EPUB and Kindle. Book excerpt: The idea of combining drugs and diagnostics in oncology is not new. When the selective estrogen receptor modulator tamoxifen was developed in the 1970’s for the treatment of breast cancer a positive correlation between receptor status and treatment outcome was found. As a result of this research, it was suggested to use the estrogen-receptor assay as a diagnostic test for selection of patients for tamoxifen treatment. Despite this suggestion was put forward nearly 40 years ago the adaptation of the drug-diagnostic co-development model has been relatively slow and it is only within the last decade that it has gained more widespread acceptance. The parallel development of the monoclonal antibody trastuzumab (Herceptin®, Roche/Genentech) and the immunohistochemistry assay for HER2 protein overexpression (HercepTest™, Dako) seems to have served as an inspiration to a number of stakeholders such as pharma and diagnostic companies, regulatory agencies, and academia. In recent years we have seen an increasing number of oncology drug development projects that have taken advantage of the drug-diagnostic co-development model, as outline below. Most of the new targeted anti-cancer drugs that have been introduced in recent years, such as BRAF-, ALK-, EGFR- and HER2-inhibitors, are more or less all a product of the drugdiagnostic co-development model. These drugs have shown remarkable high response rates in selected groups of patients within cancer diseases with great unmet medical needs. This Research Topic on Drug-Diagnostic Co-Development in Oncology aims to provide you with an insight into some of the diverse activities that constitute this new research area.

Available in PDF, EPUB and Kindle. Book excerpt: The technique of in situ hybridization, in its various forms, has been used routinely in many laboratories for a number of years. In the post-genome era, gene arrays and proteomics have allowed us to identify hitherto unknown unrecognized pathways and mechanisms. However, rather than diminish the importance of in situ hybridization, the now widespread use of screening te- nologies has increased the need to temporally and spatially localize the dist- bution of mRNA expression. Our intention, in In Situ Hybridization Protocols is to provide ample inf- mation for novices planning to set up the in situ hybridization technique and use it in their laboratory for the first time, as well as giving updates of recent developments for those laboratories where in situ hybridization techniques are already in use. Despite its widespread significance, in situ hybridization has retained a re- tation as one of the more difficult and capricious molecular biological te- niques. This may in part be because of the hybrid nature of the technique, which often requires a mixture of molecular biological and histological skills. The two techniques are usually taught and acquired in different streams of biolo- cal science. The step-by-step and detailed protocols provided in In Situ Hybridization Protocols by researchers active in the field should make it p- sible for both the molecular biologist with little experience of histology and the histologist with little experience of molecular biology to use the technique s- cessfully in their laboratories.

Available in PDF, EPUB and Kindle. Book excerpt: It is an authentic privilege to have the opportunity to assemble and edit a new volume on "Prolactin," the first in several decades to be devoted to this fascinating hormone in all its aspects. The obvious clinical rationale for understanding prolactin (PRL) is the frequent occurrence of prolactinomas, the most common type of pituitary tumor. Fortunately, medical management of prolactinomas can be based on our under standing of the physiology of hypothalamic control of the lactotroph. Armed with this knowledge, therapies for proiactinomas are highly successful and well tolerated. Be cause of the historical and practical importance of knowledge regarding the hypothala mus-Iactotroph axis, the first chapters of this volume are dedicated to reviewing the physiology, development, and cell biology of lactotroph regulation. Chapters focusing on prolactinomas and related clinical issues follow these. PRL is the primary hormone that is responsible for "parental care" in many verte brate species. This reproductive strategy is not unique to mammals, but it has devel oped through evolution to be the central distinguishing feature of the mammalian life cycle. Among the mammals, mice have become the most effective research species in recent years. This can be traced to the development of a wide range of methods for manipulating mouse genetics, and thereby influencing development, physiology and behavior. Mice also provide a profound illustration of the physiological challenges faced in maternity. Female mice undergo a post-partum estrous, and often are both pregnant and lactating simultaneously.
