The enormous expansion of the Social Security system over the last four decades has left the government very heavily involved in determining the savings and insurance of American households. While the growth of Social Security has been very substantial, it has also been gradual; this may explain the lack of focused debate on the pros and cons of government intervention in private saving and insurance decisions. This paper discusses the rationale for government intervention in this area as well as the evidence supporting the need for such intervention. While arguing the case for government provision of Social Security, the paper also points out significant shortcomings in the current system and suggests several needed reforms. 相似文献

Purpose. The present study compared attitudes about Human Rights (HR) and the advocation of coercive interviewing practices amongst Indian Police Officers, Offenders and a sample from the General Public. Method. 100 Police Officers, 50 Offenders and 50 members of the General Public completed a questionnaire that assessed their attitudes about the Human Rights of suspects and the use of coercion in suspect interviews. Results. Police Officers and the Public accepted both custodial violence and the use of intimidating interrogation strategies more readily than Offenders. They were also more prepared to suspend Suspects' Human Rights. Further, individuals who scored high on a coercive belief scale (CBS) were particularly inclined to favour custodial violence and suspend Human Rights. In addition, the self‐reported frequency with which Police Officers used intimidating and non‐intimidating interviewing techniques was related to their beliefs about Suspects' Human Rights and the extent to which they perceived intimidating interviewing methods to be useful. Conclusion. Attitudes about effective interviewing strategies may well be embedded within a broad social context. The effectiveness of a Human Rights Agenda requires that officers in India are informed of the effectiveness of ethical interviewing standards and the practical and legal dangers of using inappropriate methods. 相似文献

The literature on political control of bureaucracy reveals that bureaucracies are highly responsive to political forces. This paper argues that the political control literature misses evidence from other academic literature that bears directly on this phenomenon. Specifically, researchers need to consider the values of the bureaucracy in any effort to assess the degree of political control. An empirical test is presented using a data set from public education. Results show bureaucratic values to be far more influential in explaining bureaucratic outputs and outcomes than political factors. These findings suggest that a reinterpretation of previous empirical research is urgently in order. 相似文献

A method for determination of residual solvents in illicit hydrochloride cocaine samples using static headspace-gas chromatography (HS-GC) associated with a storage computerized procedure is described for the profiling and comparison of seizures. The system involves a gas chromatographic separation of 18 occluded solvents followed by fully automatic data analysis and transfer to a PHP/MySQL database. First, a fractional factorial design was used to evaluate the main effects of some critical method parameters (salt choice, vial agitation intensity, oven temperature, pressurization and loop equilibration) on the results with a minimum of experiments. The method was then validated for tactical intelligence purposes (batch comparison) via several studies: selection of solvents and mathematical comparison tool, reproducibility and "cutting" influence studies. The decision threshold to determine the similarity of two samples was set and false positives and negatives evaluated. Finally, application of the method to distinguish geographical origins is discussed. 相似文献

A previous study conducted in 1995 showed that psychoactive drug use by workers was higher in safety/security workstations than in the rest of the labour force. In order to verify this finding, we conducted a new study in 2003-2004 in the Nord-Pas-de-Calais region, restricted to truck drivers. The aim of this study was to allow harmonizing the professional practice of the occupational physicians, proposing drug prevention and drug testing policies, validating the analytical methods and the guidelines in case of positive testing results. One thousand truck drivers were studied. Urines were tested for amphetamines, cannabinoids, cocaine, opiates, benzodiazepines, buprenorphine and methadone by immunoassay. Urine ethanol determinations were performed by an ADH method. Positive urines for drugs of abuse, methadone or buprenorphine were then tested by gas chromatography or liquid chromatography coupled to mass spectrometry. Out of the 1000 drivers, cannabinoids were detected in 85 cases, opiates in 41 cases, amphetamines in 3 cases and cocaine in only one case. Buprenorphine was detected in 18 cases, methadone in 5 cases and benzodiazepines in 4 cases. Urine ethanol was positive in 50 cases. We found only one case with 6-monoacetylmorphine. Other positive opiates were metabolites of antitussives. The relatively low number of benzodiazepine positive urines could be explained by the lack of sensitivity of the test we used. All these results confirm those of the previous study for cannabinoids and ethanol in safety/security workstations. Positive results for methadone and buprenorphine are eight times higher than in the general population. In conclusion, the authors think that it will be of a great interest to test urine of truck drivers for other classes of psychoactive drugs, using a liquid chromatography-mass spectrometry method. 相似文献
