Abstract

The field of Walkable Neighborhood Systems is about neighborhoods as systems of land use, mobility, and transportation pricing, and how they can be understood as dense areas delineated by attractive walking distances. To date, four papers have been published in this field: Neighborhood density and travel mode (Lewis in Int J Sustain Dev World Ecol, 2018. https://doi.org/10.1080/13504509.2017.1321052), Walkable Neighborhood Systems (Lewis and Adhikari), San Francisco's neighborhoods and auto dependency (Lewis and Grande in Cities, 2019. https://doi.org/10.1016/j.cities.2018.12.017), and the Mismeasurement of Mobility for Walkable Neighborhood Systems (Lewis et al., Mismeasurement of Mobility for Walkable Neighborhood Systems, Mineta Transportation Institute, 2020). This paper summarizes the concepts and definitions of the field and replicates for Boston the methodology used in the San Francisco case study. We found 54 Boston neighborhoods using maps in a GIS and guidelines to determine neighborhood boundaries based on walking distances and land use. We establish much higher accuracy than using census blocks. We analyze neighborhood density as our independent variable and three dependent variables: sustainable modes (mode split), food sources, and walk score. The data is presented in tables, correlations, and choropleth-based graphics. Density correlated strongly with the dependent variables. The paper concludes with ideas about how to improve the performance of Walkable Neighborhood Systems for affordability, sustainability, mobility, health and safety, design, and community.

Abstract

Combined cooling, heating, and power (CCHP) systems can provide significant economic value due to the simultaneous energy production of a single source. The objective of this investigation is to examine the economic feasibility of CCHP systems of differently sized for a large office building in three locations: San Francisco, CA, Boston, MA, and Miami, FL. The economic value is evaluated with respect to annual operation costs and simple payback periods compared to a conventional, separate heat and power system wherein electricity is supplied by a grid and heat is provided by a boiler. Regionally-varying utility rates are used to examine regional impacts on the CCHP economic viability. The results show that annual operation costs can be reduced by 0.11 - 0.42 million $/y for San Francisco and Boston whereas increase by 0.16 - 0.29 million $/y for Miami. A larger system can achieve greater cost savings, but an over-sized system may lead to undesirable part load utilization of system components. For San Francisco and Boston, the annual cost savings are mainly attributed to the reduction of the grid electricity use. As a result, simple payback years of 7.5 - 10 years are noted for San Francisco and Boston. However, for Miami with relatively expensive natural gas and low grid electricity cost compared to Boston and San Francisco, the annual operation cost increases compared to the conventional system regardless of system sizes, indicating that CCHP systems may not be economically viable.

ACADEMIC-industrial collaboration, BIOTECHNOLOGY industries
Abstract

The article reflects on the SciCafé, a series of networking events that help researchers connect with investors and serial entrepreneurs in Boston, Massachusetts and San Francisco, California. SciCafé is designed to connect commercially-oriented academics with the local business community. It will link the best and brightest researchers and business people within a biohub. The relevance of SciCafé to the biotechnology sector is emphasized.

Abstract

The article discusses how researchers in San Francisco, California, and Boston, Massachusetts, reported that a virulent, multidrug-resistant form of staph bacteria was spreading among gay men. According to initial reports, Boston gays were 13 times more likely to be infected than area residents in general. The article explains that the report sparked widespread concern, which echoed similar homophobic sentiments during the early periods of AIDS and HIV. Researchers at the University of California in San Francisco would go on to revise their statements and downplay the role of gay men and the bacteria. Doctors in Boston would also go on to report that the staph bacteria did not originate with gay men. The doctors noted that the bacteria was most common in hospitals and among groups.

Abstract

The article focuses on the problems surrounding Barry Bonds who is the outfielder for the San Francisco Giants of San Francisco, California. According to the article, Bonds is, at the same time, one of the most talented hitters and disliked players in major-league baseball. His family pedigree reaches back generations including his father, Bobby Bonds, who played with the San Francisco Giants and his godfather, the Hall of Fame outfielder, Willie Mays. In the year 2004 Bonds declared Boston, Massachusetts as being too racist and could never finish his career playing for the Boston Red Sox. African-Americans in professional sports along with Bonds's issues with race and steroids are discussed.
