A gateway at the U.S.-Mexico border, Tijuana is a complex urban center with a sizeable population of sex workers. An in-depth case study of the trade, Sex Work and the City is the first major ethnographic publication on contemporary prostitution in this locale, providing a detailed analysis of how sex workers' experiences and practices are shaped by policing and regulation. Contextualizing her research within the realm of occupational risk, Yasmina Katsulis examines the experiences of a diverse range of sex workers in the region and explores the implications of prostitution, particularly regarding the spheres of class hierarchies, public health, and other broad social effects. Based on eighteen months of intensive fieldwork and nearly 400 interviews with sex workers, customers, city officials, police, local health providers, and advocates, Sex Work and the City describes the arenas of power and the potential for disenfranchisement created by municipal laws designed to regulate the trade. Providing a detailed analysis of this subculture's significance within Tijuana and its implications for debates over legalization of "vice" elsewhere in the world, Katsulis draws on powerful narratives as workers describe the risks of their world, ranging from HIV/AIDS and rape (by police or customers) to depression, work-related stress, drug and alcohol addiction, and social stigma. Insightful and compelling, Sex Work and the City captures the lives (and deaths) of a population whose industry has broad implications for contemporary society at large.

US-Mexico border region area has unique social, demographic and policy forces at work that shape the health of its residents as well as serves as a microcosm of migration health challenges facing an increasingly mobile and globalized world. This region reflects the largest migratory flow between any two nations in the world. Data from the Pew Research Center shows over the last 25 years there has never been lower than 140,000 annual immigrants from Mexico to the United States (with peaks over 700,000). This migratory route is extremely hazardous due to natural (e.g., arid and hot desert regions) and human made barriers as well as border enforcement practices tied to socio-political and geopolitical pressures. Also, reflecting the national interdependency of public health and human services needs, during the most recent five year period surveyed the migratory flow between the US and Mexico has equaled that of the flow of Mexico to the US--both around 1.4 million persons. Of particular public health concern, within the US-Mexico region of both nations there is among the highest disparities in income, education, infrastructure and access to health care--factors within the World Health Organization’s conceptualization of the Social Determinants of Health, and among the highest rates of chronic disease. For instance obesity and diabetes rates in this region are among the highest of those monitored in the world, with adult population estimates of the former over 40% and estimates in some population sub-groups for the latter over 20%. The publications reflected in this Research Topic, all reviewed from experts in the field, addressed many of the public health issues in the US Mexico Border Health Commission’s Healthy Border 2020 objectives. Those objectives-- broad public health goals used to guide a diverse range of government, research and community-based stakeholders--include Non Communicable Diseases (including adult and childhood obesity-related ones; cancer), Infectious Diseases (e.g., tuberculosis; HIV; emerging diseases--particularly mosquito borne illnesses), Maternal and Child Health, Mental Health Disorders, and Motor Vehicle Accidents. Other relevant public health issues affecting this region, for example environmental health, binational health services coordination (e.g., immunization), the impact of migration throughout the Americas and globally in this region, health issues related to the physical climate, access to quality health care, discrimination/mistreatment and well-being, acculturative/immigration stress, violence, substance use/abuse, oral health, respiratory disease, and well-being from a social determinants of health framework, are critical areas addressed in these publications or for future research. Each of these Research Topic publications presented applied solutions (e.g., new programs, technology or infrastructure) and/or public health policy recommendations relevant to each public health challenge addressed.

In her Brookings Essay, The Wall, Brookings Senior Fellow Vanda Felbab-Brown explains the true costs of building a barrier along the U.S.-Mexico border, including (but not limited to) the estimated $12 to $21.6 billion price tag of construction. Felbab-Brown explains the importance of the United States' relationship with Mexico, on which the U.S. relies for cooperation on security, environmental, agricultural, water-sharing, trade, and drug smuggling issues. The author uses her extensive on-the-ground experience in Mexico to illustrate the environmental and community disruption that the construction of a wall would cause, while arguing that the barrier would do nothing to stop illicit flows into the United States. She recalls personal interviews she has had with people living in border areas, including a woman whose family relies on remittances from the U.S., a teenager trying to get out of a local gang, and others.

Both research and consultations over the last decades have identified sexuality-related communication as an issue that requires urgent attention. While clients would like their health-care providers to discuss sexual health concerns, health workers lack the necessary training and knowledge to feel comfortable addressing such issues. This guideline provides health policy-makers and decision-makers in health professional training institutions with advice on the rationale for health-care providers' use of counselling skills to address sexual health concerns in a primary health care setting.

Rising densities of human settlements, migration and transport to reduce distances to market, and specialization and trade facilitated by fewer international divisions are central to economic development. The transformations along these three dimensions density, distance, and division are most noticeable in North America, Western Europe, and Japan, but countries in Asia and Eastern Europe are changing in ways similar in scope and speed. 'World Development Report 2009: Reshaping Economic Geography' concludes that these spatial transformations are essential, and should be encouraged. The conclusion is not without controversy. Slum-dwellers now number a billion, but the rush to cities continues. Globalization is believed to benefit many, but not the billion people living in lagging areas of developing nations. High poverty and mortality persist among the world's 'bottom billion', while others grow wealthier and live longer lives. Concern for these three billion often comes with the prescription that growth must be made spatially balanced. The WDR has a different message: economic growth is seldom balanced, and efforts to spread it out prematurely will jeopardize progress. The Report: documents how production becomes more concentrated spatially as economies grow. proposes economic integration as the principle for promoting successful spatial transformations. revisits the debates on urbanization, territorial development, and regional integration and shows how today's developers can reshape economic geography.

This report is one of several studies conducted by UNODC on organized crime threats around the world. These studies describe what is known about the mechanics of contraband trafficking - the what, who, how, and how much of illicit flows - and discuss their potential impact on governance and development. Their primary role is diagnostic, but they also explore the implications of these findings for policy. Publisher's note.
