  • Human development has different meanings depending on the area we will focus on. It is the ontogenetic process of individual development for psychologists. It considers systematic psychological changes in several areas, such as motor, cognitive, emotional, social, that occur in human beings over the course of their life span. To sociologists and economists, among others, human development is the consideration of the macrolevel countries or regions and their development conditions related to human needs.

  • This book addresses the fundamental questions concerning the economic reinvigoration of society through policies aimed at encouraging the development of small enterprises. Governments in Europe, the rest of the industrialised world and developing countries are increasingly including small enterprise development as a central feature of economic and social policies. Nowhere was this more evident than during the 1980s in Britain, as the Conservative government sought to establish an enterprise culture.

  • When retrograde dissociative amnesia is accompanied by suddenly leaving the customary environment and compromised knowledge about personal identity – the condition is named dissociative fugue. Fugues have been reported for over a century, though they were frequently erroneously associated with epilepsy (e.g., Burgl, 1900; Donath, 1899). A century ago, these conditions were named Wanderlust in Germany (cf e.g. Burgl, 1900). Fugue states were described to be preponderant in children and young adults (Dana, 1894; Donath, 1908).

  • But then another side of the issue comes to the fore. The landscapes that we ordinarily know are not pristine nature, but cultivated landscapes, rural or pastoral, with their towns and cities. Over the centuries, people have worked out their geography with multiple kinds of industry and perception, mixing nature and culture in diverse ways, no doubt some better, some worse. But who is to say that a science-based appreciation is the only right one? 9 Nature as seen by science is just the way we Westerners currently 'constitute' our world—so the phenomenologists may say.

  • Agricultural biotechnology offers great promise for Africa and tissue culture and marker-assisted selection are already in widespread use across the continent. However, the safe application of these technologies requires functioning biosafety systems. The report focuses on the special issues related to biosafety in Africa.Crops can be improved by conventional breeding, by tissue culture and by marker-aided selection. But for many improvements - such as drought and salinity tolerance - GM technology is going to be essential.

  • Tissue culture was first devised at the beginning of the twentieth century [Harrison, 1907; Carrel, 1912] (Table 1.1) as a method for studying the behavior of animal cells free of systemic variations that might arise in vivo both during normal homeostasis and under the stress of an experiment. As the name implies, the technique was elaborated first with undisaggregated fragments of tissue, and growth was restricted to the migration of cells from the tissue fragment, with occasional mitoses in the outgrowth.

  • Ten years ago when I wrote the foreword to the first edition of this book, the concept of women’s health was changing at a rapid pace. The focus was just shifting from solely reproductive issues and biological factors, to an expanded perception that women’s health encompasses biological, familial, cultural, economic, emotional, psychological, and behavioral elements of each woman and her sociopolitical environment, beyond just the reproductive organs and across her entire lifespan.

  • Because American ecocriticism, as a movement, is only about a dozen years old, generalizations about it are hard to make and still harder to validate.1 So I want to begin, not by describing the principles and practices of ecocriticism in any detail (in fact, that is something I want to delay, especially as regards the practices, until chapter four), but by looking at what seems to be, for many of its adherents, ecocriticism’s moment of origin, which is threefold in its implications.

  • Therefore, ex vivo expansion of BMSCs is required to obtain a sufficient number of transplantable cells. Since BMSCs require several kinds of supportive factors for their growth, it is standard practice to use fetal bovine serum (FBS), while autologous human serum (HS) and pooled allogeneic HS have also been used. It has been suggested that FBS may not be favorable for clinical applications due to the possible risk of contamination (prions, viruses, zoonosis) or immunological reactions against xenogeneic serum antigens (Agata et al., 2009).

  • The number one predictor of your success in today’s borderless world is not your IQ, not your resume, and not even your expertise. It’s your CQ, a powerful capability that is proven to enhance your effectiveness working in culturally diverse situations. And CQ is something anyone can develop and learn. Research conducted in more than thirty countries over the last decade has shown that people with high CQ are better able to adjust and adapt to the unpredictable, complex situations of life and work in today’s globalized world.1...

  • "It's the animal in us," we often hear when we've been bad. But why not when we're good? Primates and Philosophers tackles this question by exploring the biological foundations of one of humanity's most valued traits: morality. In this provocative book, primatologist Frans de Waal argues that modern-day evolutionary biology takes far too dim a view of the natural world, emphasizing our "selfish" genes. Science has thus exacerbated our reciprocal habits of blaming nature when we act badly and labeling the good things we do as "humane.

  • Cell culture is practiced extensively throughout the world today. The techniques required to allow cells to grow and be maintained outside the body have been developed throughout the 20th century. In the 50 years since the publication of the first human cancer cell line, HeLa (1), thousands of cell lines representing most of the spectrum of human cancer have been derived. These have provided tools to study in depth the biochemistry and molecular biology associated with individual cancer types and have helped enormously in our understanding of normal as well as cancer cell physiology.

  • The concept of 'biotech' or 'biotechnology' encompasses a wide range of procedures (and history) for modifying living organisms according to human purposes — going back to domestication of animals, cultivation of plants, and "improvements" to these through breeding programs that employ artificial selection and hybridization. Modern usage also includes genetic engineering as well as cell and tissue culture technologies.

  • According to the scheme for forests, the services are divided into five main categories: resources; ecological; biospheric; social; and amenities2. The resources category refers to all goods that may be obtained from forests (wood and non-wood); the ecological services are those related to protection of water, soil and health; the biospheric services are mainly climate regulation and biodiversity protection; while social and amenity services comprise of different types of recreational activities and the cultural importance of forests.

  • Synthetic polymers fulfill many functions in biotechnology and medicine. In cell culture technology and tissue engineering they provide the surfaces to which cells may attach. Cross-linked polymer networks are used for drug delivery and cell encapsulation. Polymer-based porous membranes can be used to shield implanted cells from the immune system of the host, while allowing for the exchange of nutrients and metabolic waste products thus keeping the cells alive and functioning.
