Ghettos and enclaves in the cross-place realm: mapping socially bounded spaces across cities

Since the early Chicago School, urban researchers have used residential proximity to assess contacts within and between racial and ethnic groups. This approach is increasingly limited. Diverse groups use email, social networking sites, instant messaging and mobile phones to communicate across urban zones and distant cities. These practices enable mutual support among far-flung family members and co-ethnics as they engage with an array of institutions throughout their day. Through interviews and observations that include women and men of diverse occupations, races and national origins, the author explores how and why cross-place enclosures of sociality and resources develop. Rather than framing the residential area as the locus of racial/ethnic concentration, the author focuses on cross-place concentrations in the technologically mediated workspace. This study enhances theorization of the structural negotiations, interpersonal pressures and group preferences that produce separate lifeworlds in globalizing cities.     

Reappearance of the Public: Placemaking,Minoritization and Resistance in Detroit

Recent studies of public space in US central cities tend to focus either on (1) market‐driven placemaking (privatized parks, hipster shops) in gentrifying enclaves or (2) street cultures (community gardens, hip‐hop) in low‐income neighborhoods. Neither focus adequately frames the ability of African Americans to shape public space as the white middle class returns to central cities. In this case study of downtown Detroit, I theorize a dialectic: the history of clashes between racial capitalism and social movements in public space reappears in the contradictory design of market‐driven placemaking, which suppresses and displays cultures of resistance. White business and real‐estate interests showcase downtown spaces to counter news of disinvestment and suffering in low‐income neighborhoods. The legal and political legacies of civil rights and black power struggles—combined with consumer demand (black culture sells)—force them to involve black entrepreneurs, professionals and artists in placemaking. This placemaking subordinates the black urban poor, even as it incorporates their street cultures. The contradictions of placemaking shape possibilities for resistance, as shown in mundane subversions and street protests that use the downtown spotlight to call for social justice citywide. This analysis contributes to research on public space at a time when new movements are challenging public order in the financial core of US cities.     

Teaching Business Ethics Through Strategically Integrated Micro-Insertions

This article identifies an integrated teaching strategy that was originally developed for engineers, the so-called ‘micro-insertion’ approach, as a practical and effective means to teach ethics at business schools. It is argued that instructors can incorporate not only generic or thematic learning objectives for students into this method (i.e., the intended content of what is being taught: in our case, an underlying ethical base for doing business), but also do so via a strategically integrated approach regarding the appropriate mix and timing of these micro-insertions. With this in mind, we propose a qualitative and example-based approach that endeavors to provide a versatile way for business teachers to incorporate ethics into their general business classes. We also present a conceptual and theoretical framework that underpins this method, and we further provide a set of specific examples and a practical table that show how business instructors might integrate ethics-oriented micro-insertions into their teaching.     

Microenvironment-specific effects in the application credit scoring model

This paper introduces the improved version of a credit scoring model which assesses credit worthiness of applicants for a loan. The scorecard has a two-level multilevel structure which nests applicants for a loan within microenvironments. In addition, the paper proposes a new type of clustering for a hierarchical two-level structure which is more intuitive and efficient in the application to credit scoring. This structure explores living area-specific effects which are viewed as unobserved determinants of default. The primary benefit of the multilevel scorecard compared to a conventional scoring model is higher accuracy of the model predictions.
