Climate 2030: A National Blueprint for a Clean Energy Economy (Executive Summary)

Courage of conviction, unyielding stamina to underscore the dangerous realities of unchanging lifestyle habits and doing business as usual in today’s world, and unfettered tenacity necessary to build an ever-growing network of dedicated individuals and scientists struggling to express the need for public awareness and governmental action, describes this nationwide group. The Union of Concerned Scientists, primarily headquartered in Cambridge, Massachusetts, presents its forecast for 2030 – complete with the recipe needed to be undertaken for individuals and businesses to both survive and thrive

Do immigrants pose a fiscal burden on the host country budget? : a case study for Michigan.

Using i) the Public Use Micro Sample data from the 2000 US Census of Population and Housing, and ii) fiscal information from the state of Michigan Budget Office, we estimate the net (benefit minus cost) fiscal impact of immigrants in the state of Michigan. We have shown that both immigrant and native-born households are fiscal burden to the state although financial burden for native-born households is less that that for foreign-born households. When we classify immigrants by their country of origin, immigrants from some specific countries actually add a net amount to the state coffer.Immigrants, Tax Revenues, and Government Expenditure

Negotiating identities: ethnicity and social relations in a young offenders' institution

This article explores the situated nature of male prisoner identities in the late modern British context, using the contrasting theoretical frames of Sykes's (1958) indigenous model and Jacobs' (1979) importation model of prisoner subcultures and social relations. Drawing on eight months of ethnographic fieldwork in an ethnically, religiously and nationally diverse young offenders institution, consideration is given to how prisoners manage and negotiate difference, exploring the contours of racialization and racism which can operate in ambiguous and contradictory ways. Sociological understandings of identity, ethnicity, racialization and racism are used to inform a more empirically grounded theoretical criminology

Electronic transport in polycrystalline graphene

Most materials in available macroscopic quantities are polycrystalline. Graphene, a recently discovered two-dimensional form of carbon with strong potential for replacing silicon in future electronics, is no exception. There is growing evidence of the polycrystalline nature of graphene samples obtained using various techniques. Grain boundaries, intrinsic topological defects of polycrystalline materials, are expected to dramatically alter the electronic transport in graphene. Here, we develop a theory of charge carrier transmission through grain boundaries composed of a periodic array of dislocations in graphene based on the momentum conservation principle. Depending on the grain boundary structure we find two distinct transport behaviours - either high transparency, or perfect reflection of charge carriers over remarkably large energy ranges. First-principles quantum transport calculations are used to verify and further investigate this striking behaviour. Our study sheds light on the transport properties of large-area graphene samples. Furthermore, purposeful engineering of periodic grain boundaries with tunable transport gaps would allow for controlling charge currents without the need of introducing bulk band gaps in otherwise semimetallic graphene. The proposed approach can be regarded as a means towards building practical graphene electronics.Comment: accepted in Nature Material

Achieving favourable customer outcomes through employee deviance

This study advances current knowledge by examining how employee deviance and customer participation during a single employee-customer exchange generate favourable customer responses. This work bridges the employee deviance stream with the service encounter literature and illustrates the importance of equity theory in deviant service exchanges between customers and employees. Moreover, results add to the ongoing debate on service nepotism by canvassing the consequences from the customer’s active participation in deviant exchanges which appears to enhance customer perceptions of the exchange. A 3x2 between-subjects experimental design was adopted which manipulates three types of pro-customer deviance along with customer’s participation (or not) to the exchange. The dependent variables capture three types of perceived customer justice (cognitive outcomes) and customer’s affective state (affective outcome). Findings illustrate that customers approve employees’ deviance for their own benefit while also indicate favourable outcomes from deviant exchanges with employees such as higher perceived justice and a more positive affective state. The article concludes with a discussion of the theoretical and managerial implications, limitations and research directions that emerge from this study

Gangs, Guns, and Drugs: Recidivism among Serious, Young Offenders

The primary goal of this study is to understand the factors that best explain recidivism among a sample of 322 young men aged 17 to 24 years released from prison in a Midwestern state. Specific attention is paid to the predictive validity of gang membership, gun use, and drug dependence on the timing of reconviction and the current research on desistance frames the analyses. Results from a series of proportional hazard models indicate that race, gang membership, drug dependence, and institutional behavior are critical factors in predicting the timing of reconviction. Contrary to expectations, gun use was not related to postrelease involvement in the criminal justice system
