Latinos in the United States have poor outcomes for periodontal and dental health. However, a detailed description of the mechanisms driving these patterns has only recently started to be addressed in the literature. In the current study, we explore relationships between individual-level characteristics of Mexican immigrants, properties of their networks, and experiences of dental problems. Specifically, using data from an urban community of Mexican immigrants to the American Midwest (n = 332), this study examines how characteristics of oral health matters (OHM) discussion networks and individual-level sociodemographic characteristics are associated with four adverse oral health outcomes. The results provide strong support for relationships between immigrants’ network characteristics and dental problems. We find that people with more dental problems talk about these issues more frequently with network ties. Conversely, stronger relationships with OHM discussion networks, as measured by mean closeness, are predictive of fewer dental problems. In addition, we identify a link between perceptions of alters’ knowledge about teeth, mouth, and gums and egos reporting better oral health outcomes. The observed patterns are suggestive of mechanisms of social influence that are well replicated in the social, medical, and public health literatures, but that have seldom been empirically tested in the domain of oral health. Though preliminary, our findings suggest a potential explanatory role for social networks in some of the most important questions and problems in oral health disparities research. In all, our findings suggest that social network members are active participants in the management and response to oral health problems in this immigrant group and should be considered an important factor in the development and course of diseases.

The public’s awareness of noise and vibration forms a significant barrier to further development of railways. This chapter begins with a short introduction to the main fundamental aspects of acoustics, including decibels, frequency analysis, the propagation of sound with distance and common measurement quantities. The main sources of railway noise are discussed, including rolling noise, impact noise, curve squeal and aerodynamic noise. Simple calculation procedures are described that can be used to assess the impact of railway noise and to compare it with legal limits. The final section is devoted to ground vibration, which is a related form of environmental disturbance.

In November 2001, Scott Carlson, in the Chronicle of Higher Education wrote an article on library use titled “The deserted library: As students work online, reading rooms empty out—leading some campuses to add Starbucks” (Carlson, 2001). The essence of this chapter is that many librarians, facing dramatic declines in library gate counts resulting from the wealth of electronic resources accessible remotely, were beginning to move away from traditional conceptions of the library as primarily a repository for print collections. Carlson describes the “tough sell” that the Georgia College and State University in Milledgeville had experienced when planning a $19.5 million library addition in the mid-1990s. In response librarians had begun “fighting back” with “plush chairs, double-mocha lattes, book groups, author readings.” Still, no one knew whether these stratagems would enhance learning or bring its readers back.

Purpose – There has been a growing interest in the development of a ‘green’ or ‘low carbon’ economy as a means of reconciling economic development and the environment. Research on green entrepreneurs to date has been upon individual entrepreneurs, neglecting wider economic and social contexts within which they operate. By looking at these wider networks of support, we suggest that discourses of the lone entrepreneur innovating and changing business practices are misrepresentative.

Methodology/approach – Semi-structured interviews to investigate green entrepreneurship with green building companies and policy makers.

Findings – Combined with new demands from consumers for more environmentally friendly products and services, the changing shape of national and global economies is leading to new forms of entrepreneurship. We identify a number of tensions between policy intentions and businesses’ experiences on the ground.

Research limitations/implications – To date, research has only been undertaken in the UK – we recommend that future research takes other national contexts into account. Other economic sectors also represent promising areas for future research, potentially including social enterprises in the green economy. Sustainability transitions theories offer a potentially valuable means for understanding the role of businesses in engendering a green economy.

Practical implications – Implications for policy frameworks are outlined in the conclusions.

Originality/value of chapter – By incorporating policy and support organisations, and informal networks of support, the chapter challenges the dominant view of the lone entrepreneurial hero and points to the significance of networks for facilitating green entrepreneurship. This will be of importance for policy makers and funders of entrepreneurship programmes.

This book is divided into four parts: (1) Institutions and policy, (2) The economics of hazards, (3) Community involvement, and (4) Management and ecology. The first section contains four chapters that cover the issue of wildfire from historical and institutional perspectives. “Forest fire history: learning from disaster” by Roger Kennedy (Chapter 2) addresses the pressures and politics giving rise to the current situation. “Fire Policy in the Urban–Wildland Interface in the United States: What are the Issues and Possible Solutions?” (Chapter 3) by Scott Stephens and Brandon Collins provides a summary of the problems associated with wildfire hazards in UWI communities, discusses fuels-treatment options for local governments and property owners, and analyzes challenges to planning, drawing on experiences from Australia. “Wildfire hazard mitigation as “safe” smart growth” (Chapter 4) by Robert Paterson looks at how smart growth principals are being adapted to fire-safe land use planning and zoning, including a discussion of the role of regional coordination and state-level planning requirements. “Practical and institutional constraints on adopting wide-scale prescribed burning: lessons from the mountains of California” (Chapter 5) by Kurt Menning details the problems of fuel accumulation due to suppression, the potential power of prescribed burning as a management tool, and the social and regulatory obstacles to implementing wide-scale prescribed burning programs.
