Beginning in the late 1970s and early 1980s,significant numbers of Haitian immigrants began to arrive and settle in Miami.Overcoming some of the most foreboding obstacles ever to face immigrants inAmerica, they, their children, and now their grandchildren, as well as morerecently arriving immigrants from Haiti, have diversified socioeconomically.Together, they have made South Florida home to the largest population ofnative-born Haitians and diasporic Haitians outside of the Caribbean and one ofthe most significant Caribbean immigrant communities in the world. Religion hasplayed a central role in making all of this happen. Crossing the Water and Keeping the Faith is a historical andethnographic study of Haitian religion in immigrant communities, based onfieldwork in both Miami and Haiti, as well as extensive archival research.Where many studies of Haitian religion limit themselves to one faith, Rey andStepick explore Catholicism, Protestantism, and Vodou in conversation with oneanother, suggesting that despite the differences between these practices, thethree faiths ultimately create a sense of unity, fulfillment, and self-worth inHaitian communities. This meticulously researched and vibrantly written bookcontributes to the growing body of literature on religion among new immigrants,as well as providing a rich exploration of Haitian faith communities.
The Chemical Biology of Sulfur
This volume aims to provide an in-depth view of the complete biochemistry of sulfur with an emphasis on aspects not covered elsewhere. Given its role in the formation of proteins and presence in the amino acids methionine and cysteine, sulfur is essential to life. Current literature on the biochemistry of sulfur is vast and widely dispersed, as such this volume is intended as a single-source for everything concerning sulfur biochemistry from metabolic roles of inorganic sulfur, to thiol and thioether chemical biology, to the university of cysteine chemistry in proteomes. Authored by a renowned biochemist and experienced writer and educator, this book is ideal for students and researchers in biochemistry, biology and the life sciences with an interest in sulfur and its role in life.
Carbon Nanotubes in Drug and Gene Delivery
Recent important discoveries and developments in nanotechnology have had a remarkable and ever-increasing impact on many industries, especially materials science, pharmaceuticals, and biotechnology. Nanocarriers have been investigated for a wide variety of different medical applications. Some examples of these nanocarriers include polymersomes, liposomes, micelles and carbon-based nanomaterials. Within this book, the authors describe different features of carbon nanotubes (CNTs), survey the properties of both the multi-walled and single-walled varieties, and cover their applications in drug and gene delivery. In addition, the book explains the structure and properties of CNTs prepared by different method, and discussed their isolation and purification. The future of CNTs in the field of biomedical science will depend on minimizing their adverse effects by careful study of their structure and properties.
The Midlife Crisis of the Nuclear Nonproliferation Treaty
The Nuclear Nonproliferation Treaty (NPT) has been the principal legal barrier to prevent the spread of nuclear weapons for the past forty-five years. It promotes the peaceful uses of nuclear technology and insures, through the application of safeguards inspections conducted by the International Atomic Energy Agency (IAEA), that those technologies are not being diverted toward the production of nuclear weapons. It is also the only multinational treaty that obligates the five nuclear weapons states that are party to the treaty (China, France, Great Britain, Russia, and the United States) to pursue nuclear disarmament measures. Though there have been many challenges over the years, most would agree that the treaty has largely been successful. However, many are concerned about the continued viability of the NPT. The perceived slow pace of nuclear disarmament, the interest by some countries to consider a weapons program while party to the treaty, and the funding and staffing issues at the IAEA, are all putting considerable strain on the treaty. This manuscript explores those issues and offers some possible solutions to ensure that the NPT will survive effectively for many years to come.

Brain Development and Sexual Orientation
Sexual orientation (homo- vs. heterosexuality) is one of many sex differences observed in humans. Sex differences can result from differential postnatal experiences (interaction with parents, environment) or from biological factors (hormones and genes) acting pre- or postnatally. The first option is often favored to explain sexual orientation although it is supported by little experimental evidence. In contrast, many sexually differentiated behaviors are organized during early life by an irreversible action of sex steroids. In particular, the preference for a male or female sex partner is largely determined in rodents by embryonic exposure to sex steroids. The early action of these steroids also seems to affect sexual orientation in humans. Indeed, clinical conditions associated with major endocrine changes during embryonic life often result in an increased incidence of homosexuality. Furthermore, multiple sexually differentiated behavioral, physiological, or even morphological traits that are known to be organized by prenatal steroids, at least in animals, are significantly different in homo- and heterosexual populations. Thus, prenatal endocrine (or genetic) factors seem to influence significantly human sexual orientation even if a large fraction of the variance remains unexplained to date. The possible interaction between biological factors acting prenatally and postnatal social influences remains to be investigated.
