Urban spatial form influences the social, economic, and ecological development modes of the city. The spatial form during the urbanization of Hanjiang River Basin in Southern Shaanxi needs to be studied. In this study, research methodologies on urban spatial form in China and abroad were summarized. The concept of ecology background was applied, and the research framework for urban spatial form, which integrated the background, framework, core, axis, cluster, and skin, was established. Valley cities in the Hanjiang River Basin in Southern Shaanxi were classified into wide valley, narrow valley, and canyon cities. The spatial form characteristics of these three types of valley cities were discussed. A case study based on a typical city-Yang County-was conducted to discuss the characteristics of the aforementioned six elements of urban spatial form. Finally, spatial form characteristics were summarized. These characteristics provide a basis for the study of the small valley urban spatial form in the Hanjiang River Basin in Southern Shaanxi.

The national immigrant rights campaign of 2006 stands as one of the largest mobilizations by people of color in US history, yet less scholarly attention has been given to systematically comparing these mobilizations at the local level. To develop an understanding of what led to sustained mobilization, a comparative case study analysis of seven cities in California's San Joaquin Valley is employed. The empirical evidence is based on interviews with key organizers and participants, newspaper documentation of protest events, census data, and other secondary sources. I find that the presence and size of policy threats explained the initial protest during the spring of 2006 in all localities, but cities with elaborate resource infrastructures (preexisting organizations, histories of community organizing, and coalitions) had more enduring levels of collective action.

The purpose of this paper is to investigate the role that agency culture, training, and supervision play in the rates of on-the-job seatbelt use among peace officers, as well as other officer safety-related driving concerns such as cell phone use, Mobile Data Terminal use, and other sources of distraction.

Based on semi-structured interviews with California peace officers.

This study found an array of agency culture issues related to on-duty collisions, including distraction, failure to follow policy or procedure, fatigue, self-selection processes among officers and agencies, supervision and field training processes, morale issues, and family/lifestyle issues.

To explain these agency culture findings, this paper introduces the concept of the “banality of risk” to understand why many officers choose not to use risk-attenuating equipment. The findings are suggestive of a set of best practices that agencies could consider regarding in-vehicle officer safety.

Governor Robert F. Casey made his first state visit to Homestead, Pennsylvania the day after his inauguration in January 1987 to announce a package of plans for restoring economic vitality to metropolitan Pittsburgh in the wake of steel's collapse. Earlier urban renewal had involved large-scale demolition of older downtowns for conversion to commercial and industrial use, but state and local officials now emphasized a two-pronged redevelopment approach largely modeled on the success of the postwar suburbs. The closure of the Monongahela River (Mon) Valley's mammoth steel mills opened large swaths of land and prompted calls for planned riverfront manufacturing and retail districts similar to those sites sprouting up at suburban interchanges. A second and related effort involved schemes to build new highways tying aging communities in the river valleys to both Pittsburgh and new suburban growth areas, such as the sprawling “edge city” of Monroeville less than 10miles away. Indeed, Casey had a special project in mind for revitalizing the iconic Homestead – construction of the long-delayed Mon/Fayette Expressway that would parallel the river south of Pittsburgh. “This is another big step [to] help bring businesses and jobs into the region,” the governor later declared. “No longer is this valley a forgotten valley” (as cited in Basescu, 1989, p. 1).

This chapter examines issues of sustainability in regard to post-Soviet Central Asian urban centers via a case study of Bishkek, Kyrgyzstan. This urban center of approximately one million people is the largest in the Kyrgyz Republic, and one of the larger cities in Central Asia. Dubbed “the Tree City” during the Soviet Era, it, like other Central Asian population centers, occupies an oasis-like environment at the foot of a major mountain range, the Ala-Too Range of the Tian Shan (Mts.). This major mountain massif, which extends across the northern part of Central Asia and on into North-West China, has numerous peaks more than 4,000 m high and many glaciers. It is these snowfields that provide most of the water used by the city of Bishkek and its suburbs.

The findings represented herein are based on ethnographic field observations and interviews conducted in 2006–2007 and 2013–2014. A variety of documentary resources were accessed as well.

During Soviet times, Bishkek and its environs were the location of industrial complexes focused on the processing of minerals and agricultural produce, much of which was shipped to other republics within the USSR. Since the collapse of the Soviet Union, many of these industrial sites have fallen into disuse and disrepair. So, while Bishkek has numerous “socialist” planned parks, long-established green spaces, and a relatively large “urban forest” along major boulevards and thoroughfares, it is also dotted with abandoned factories, warehouses, and crumbling infrastructure. In parts of the city, and especially around its perimeter, urban fruit and vegetable gardens have reappeared, as many residents had to return to subsistence gardening to provide basic food needs for their households.

In the last decade, however, the local economy has begun to diversify and grow. This has brought more cars to the streets and a substantial number of new businesses and building projects, along with increasing amounts of air, water, and noise pollution. Concomitant with this new development has been the emergence of a nascent green movement, the establishment of environmental organizations, and a small but growing “green consciousness” as witnessed by the creation of new recycling programs, increased bicycle travel, and related activities pointing toward a more sustainable future.

In this chapter, the relative sustainability (social, cultural, economic, and ecological) of this Central Asian urban center are considered as it has emerged from its Soviet past to become the focal point of new enterprises, including a small but growing ecotourism industry. Bishkek, in common with other major cities of this region, which is far from the moderating influences of the sea, must adapt to the realities of what are likely to be increasingly severe climate change impacts – increased average annual temperatures, the rapid retreat of mountain glaciers and a reduction in the essential waters that they provide, and increasingly severe and numerous periods of drought. Whether or not Bishkek can successfully adapt to these changes and emerge as a more sustainable city remains to be seen.

Culture has always been important for the character of the cities, as have the civic and public institutions that sustain a lifestyle and provide an identity. Substantial evidence of the unique historical, urban civilisation remains within the traditional settlements in the Kathmandu Valley in Nepal, manifested in houses, palaces, temples, rest houses, open spaces, festivals, rituals, customs and cultural institutions. Indigenous knowledge and practices prescribed the arrangement of houses, roads, and urban spaces giving the city a distinctive physical form, character, and a unique oriental nativeness. In a technical sense, these societies did not have written rules for guiding development. In recent decades, the urban culture of the city has been changing with the forces of urbanisation and globalisation and the demand for new buildings and spaces. New residential design is increasingly dominated by distinctive patterns of Western suburban ideal comprising detached or semi-detached homes and high rise tower blocks. This architectural iconoclasm can be construed as a rather crude response to the indigenous culture and built form. The paper attempts to dismantle the current tension between traditional and contemporary ‘culture’ (and hence society) and housing (or built form) in the Kathmandu Valley by engaging in a discussion that cuts across space, time, and meaning of architecture as we know it.

Social scientists have recently turned their attention to the important consequences of industrial districts or so-called agglomeration economies on economic growth and firm performance. This paper explores an important but unanswered question involving agglomeration economies: does geographic location within an agglomeration affect firm performance? I assess this question by examining the effects of different geographic office locations (by zip code) on the failure rates of all corporate law firms located in Silicon Valley from 1969 to 1998. Empirical estimates reveal that Silicon Valley corporate law firms benefit from the increased volume of client referrals that comes from being near mutualistic firms that offer a different range of legal services, the lower labor costs and more specialized division of labor that come from being near a large joint supply of lawyers, and the increased business that comes from being near important clients (i.e. venture capital firms).

In addition, corporate law firms that locate in certain municipalities of Silicon Valley, including Palo Alto, San Jose, and Santa Clara, have significantly increased failure rates, even controlling for many firm-specific differences. Younger corporate law firms (under the age of 11 years) are helped disproportionately by being near important environmental resources and harmed disproportionately by being in certain perilous areas of Silicon Valley. All told, a law firm’s office location within Silicon Valley has significant consequences for its survival.

Small firms, which represent much of the Silicon Valley region, tend to experience losses due to their small scale, small customer base and lack of diversification. The authors study the impact of accounting conservatism and losses on firm value and as such this study is an appropriate addition to this growing field of financial management.

The authors use methodology developed in prior literature to examine Silicon Valley and non-Silicon Valley firms' and their behavior when facing losses and the factors, which might play a role in their valuation. The authors focus particularly on earnings and accounting conservatism. Accounting conservatism captures how fast firms record losses relative to gains. The faster losses are recognized than gains the more accounting conservatism is exhibited. The authors examine the seemingly unrelated estimation of differences in means for our independent variables of interest across the two samples of Silicon Valley and non-Silicon Valley firms, both earnings and accounting conservatism. The authors use matched sample analysis of these firms based on four digit SIC code, size and date. In robustness, the authors run a more in-depth propensity score matched sample analysis.

The authors document that market values of Silicon Valley firms with accounting losses are affected less by negative earnings than other firms with accounting losses in the United States outside of the Silicon Valley region, noting the “lose big, win bigger” sentiment of Silicon Valley. Additionally, the authors document that accounting conservatism does play a role in influencing valuations of companies with accounting losses both in Silicon Valley and the rest of the United States, marginally more for Silicon Valley firms.

This study would be of interest to fund managers who need to consider smaller firms for inclusion in their portfolios. A lot of small firms have experienced losses ever since going public, especially Silicon Valley start-up firms.
