Surviving Homophobia: Overcoming Evil Environments

Thinking of the evils of homophobia and what is needed to survive them requires acknowledging a new category of evil besides the evils of individual deeds, social practices and social structures. That further category is evil social environments. Building on the work of Jeremy Waldron on the harm in hate speech, this chapter extends that account to certain hate crimes that, like the written word, send a lingering social message. The cases of four women survivors of homophobia are then examined in relation to such harm. Two who wrote memoirs had been targeted for murder, one in an evil environment, the other in a more positively responsive environment. The remaining two survival stories are less dramatic. But they are important in how they illustrate ordinary challenges faced successfully by lesbians and gay men in emotionally toxic environments, and how, in this sense, those not directly threatened with murder might still be justly regarded as survivors. The chapter concludes with reflections on the meanings of survival and some of the costs of surviving an evil homophobic environment

Outlook for alternative energy sources

Predictions are made concerning the development of alternative energy sources in the light of the present national energy situation. Particular emphasis is given to the impact of alternative fuels development on aviation fuels. The future outlook for aircraft fuels is that for the near term, there possibly will be no major fuel changes, but minor specification changes may be possible if supplies decrease. In the midterm, a broad cut fuel may be used if current development efforts are successful. As synfuel production levels increase beyond the 1990's there may be some mixtures of petroleum-based and synfuel products with the possibility of some shale distillate and indirect coal liquefaction products near the year 2000

Effects of increasing the affinity of CarD for RNA polymerase on Mycobacterium tuberculosis growth, rRNA transcription, and virulence

CarD is an essential RNA polymerase (RNAP) interacting protein in Mycobacterium tuberculosis that stimulates formation of RNAP-promoter open complexes. CarD plays a complex role in M. tuberculosis growth and virulence that is not fully understood. Therefore, to gain further insight into the role of CarD in M. tuberculosis growth and virulence, we determined the effect of increasing the affinity of CarD for RNAP. Using site-directed mutagenesis guided by crystal structures of CarD bound to RNAP, we identified amino acid substitutions that increase the affinity of CarD for RNAP. Using these substitutions, we show that increasing the affinity of CarD for RNAP increases the stability of the CarD protein in M. tuberculosis. In addition, we show that increasing the affinity of CarD for RNAP increases the growth rate in M. tuberculosis without affecting 16S rRNA levels. We further show that increasing the affinity of CarD for RNAP reduces M. tuberculosis virulence in a mouse model of infection despite the improved growth rate in vitro. Our findings suggest that the CarD-RNAP interaction protects CarD from proteolytic degradation in M. tuberculosis, establish that growth rate and rRNA levels can be uncoupled in M. tuberculosis and demonstrate that the strength of the CarD-RNAP interaction has been finely tuned to optimize virulence. IMPORTANCE Mycobacterium tuberculosis, the causative agent of tuberculosis, remains a major global health problem. In order to develop new strategies to battle this pathogen, we must gain a better understanding of the molecular processes involved in its survival and pathogenesis. We have previously identified CarD as an essential transcriptional regulator in mycobacteria. In this study, we detail the effects of increasing the affinity of CarD for RNAP on transcriptional regulation, CarD protein stability, and virulence. These studies expand our understanding of the global transcription regulator CarD, provide insight into how CarD activity is regulated, and broaden our understanding of prokaryotic transcription

The Impact of Deregulation on the Employment and Wages of Airline Mechanics

This paper describes the effects of deregulation on negotiated wage rates and employment levels of aircraft mechanics in the scheduled airline industry. Firm-specific data for the incumbent trunk airlines show relatively small changes in real wage rates since deregulation,and only recent increases in interfirm wage differentials. Employment growth rates, on the other hand, have varied widely among the incumbents, and between the incumbent trunks and the local service and new-entrant airlines. The data suggest that deregulation resulted in a transfer of 5000-7000 maintenance jobs from the incumbent trunks to the smaller airlines. This shift in employment reduced mechanics' earnings in the industry by as much as 5 percent.

The Impact of the Mariel Boatlift on the Miami Labor Market

This paper presents an empirical analysis of the effect of the Mariel Boatlift on the Miami labor market, focusing on the wages and unemployment rates of less-skilled workers. The Mariel immigrants increased the population and labor force of the Miami metropolitan area by 7 percent. Most of the immigrants were relatively unskilled: as a result, the proportional increase in labor supply to less-skilled occupations and industries was much greater. Nevertheless, an analysis of wages of non-Cuban workers over the 1979-85 period reveals virtually no effect of the Mariel influx. Likewise, there is no indication that the Boatlift lead to an increase in the unemployment rates of less-skilled blacks or other non-Cuban workers. Even among the Cuban population wages and unemployment rates of earlier immigrants were not substantially effected by the arrival of the Mariels.

Unexpected Inflation, Real Wages, and Employment Determination in Union Contracts

This paper presents new microeconometric evidence on the relevance of nominal contracting for employment determination in the unionized sector. Real wages in long term union contracts contain an unanticipated component that reflects unexpected changes in prices and the degree of indexation. These unexpected wage components provide a convenient tool for separating the causal effects of wages on employment from other endogenous sources of employment and wage variation. The empirical analysis of employment and wage outcomes among collective agreements in the Canadian manufacturing sector reveals that employment and wages are only weakly related. When unexpected changes in real wages are used as an instrumental variable for the contract wage, however, employment is consistently negatively related to wages. The results imply that the institutional structure of wage determination has important effects on the cyclical characteristics and persistence of employment changes.

Authentication enhancement of RFID card using an electronically clippable shield and fingerprint-biometrics

Radio frequency identification (RFID) is a technology that employs basic identifier of an object embedded in a chip, transmitted via radio wave, for identification. An RFID Card, responds to query irrespective of ‘Who’ holds the card; like a key to a door. Since an attacker can possess the card, access to such object can therefore be easily compromised. This security breach is classified as an unauthorized use of card, and it forms the bedrock for RFID card compromise especially in access control. As an authentication enhancement mechanism, this study designed and developed a method termed BIO-THENTIC Card, that integrates three existing mitigation methods which are physical clip tag, Faraday shield and fingerprint authentication; to prevent and also protect this weakness. The Bio-Thentic Card was fabricated, tested and assessed in line with the known threats, and attacks; and it was observed to proffer substantive solution to unauthorized use of RFID Card
