Much attention has been given of late to the erosion of the "employment-at-will" doctrine. Exceptions to this doctrine began to emerge when courts held that at-will employees could sue if their termination violated public policy. The at-will doctrine was further eroded by court rulings that a contract requiring good cause in order to terminate could be inferred from employee handbooks, company personnel policies, and circumstances of employment. As the initial flood of wrongful termination lawsuits now reaches the appellate level, some guidance on the standards employers must observe can be drawn from court decisions. The authors examine these decisions as well as the legislative reform being proposed in response to them.  相似文献

An additional 20 novel mini-short tandem repeat (miniSTR) loci have been developed and characterized beyond the six previously developed by our laboratory for a total of 26 non-CODIS miniSTR markers. These new markers produce short PCR products in the target range of 50-150 base pairs (bp) by moving the primer sequences as close as possible-often directly next to the identified repeat region. These candidate loci were initially screened based on their small amplicon sizes and locations on chromosomes currently unoccupied by the 13 CODIS STR loci or at least 50 Mb away from them on the same chromosome. They were sequenced and evaluated across more than 600 samples, and their population statistics were determined. The heterozygosities of the new loci were compared with those of the 13 CODIS loci and all were found to be comparable. Only five of the new loci had lower values than the CODIS loci; however, all of these were much smaller in size. This data suggests that these 26 miniSTR loci will serve as useful complements to the CODIS loci to aid in the forensic analysis of degraded DNA, as well as missing persons work and parentage testing with limited next-of-kin reference samples.  相似文献

As organ transplantation procedures become accepted as standard medical practice, it is anticipated that the frequency of liability claims against transplant care providers will increase. This article examines current statutory and common law analyses of malpractice issues in transplantation, with particular attention given to issues of informed consent as they arise both for the organ donor and donee.  相似文献

In a further study of the addiction-crime relationship, 214 narcotic addicts were classified according to their criminal involvement during a 2-year preaddiction period. The sample was divided into two groups—those who reported involvement in any of 20 categories of criminal activity (N = 108) and those who reported no such activity (N = 106). The criminal behavior and drug-use patterns of the two groups were then compared during subsequent addiction and nonaddiction periods. As expected, the impact of addiction was much more prominent in the low-crime group. The implications of results for rehabilitation strategies are discussed.  相似文献

California's “three strikes and you're out” law is the most notorious example of the wave of mandatory sentencing policies that many states enacted beginning in the late 1970s. While advocates and critics predicted the law would have profound effects on aggregate punishment trends and individual case outcomes, Feeley and Kamin's analysis of previous sentencing reforms suggested the law's impact would be mainly symbolic because local officials would ignore, subvert, or nullify its major provisions. While aggregate analyses have tended to confirm this argument, so far there has been no systematic test of the law's effect on individual cases. This analysis uses multilevel models applied to case‐level data from 12 urban California counties to test hypotheses about shifts in average punitiveness, the relative influence of legal and extralegal factors on sentencing, and the uncertainty of sentencing outcomes. Results mostly support Feeley and Kamin's symbolic interpretation, but also reveal important substantive impacts: since Three Strikes, sentences have become harsher, particularly in politically conservative counties, and black felons receive longer prison sentences.  相似文献

Purpose

The purpose of the current study was to assess sex offender recidivism in the context of General Strain Theory (GST).

Methods

Surveys were mailed to 3,506 sex offenders with (N = 939) in Nebraska, (N = 1,850) in Kansas and (N = 717) in Montana. Questions related to strain associated with registration and community notification, anger, depression, and criminal behavior were asked. OLS Regression was utilized to predict overall recidivism, as well as sex, violent, drug, and property recidivism.

Results

Findings suggest that GST is supported when analyzing recidivism.

Conclusions

In the context of these findings, policymakers would do well to reexamine the broad use of registration and community notification laws.  相似文献

According to law enforcement, many witnesses are intoxicated either at the time of the crime, the interview, or both (Evans et al., Public Policy Law 15(3):194-221, 2009). However, no study to date has examined whether intoxicated witnesses' recall is different from sober witnesses' and whether they are more vulnerable to misinformation using an ecologically valid experimental design. Intoxicated, placebo, and sober witnesses observed a live, staged theft, overheard subsequent misinformation about the theft, and took part in an investigative interview. Participants generally believed they witnessed a real crime and experienced a real interview. Intoxicated witnesses were not different from placebo or sober witnesses in the number of accurate details, inaccurate details, or "don't know" answers reported. All the participants demonstrated a misinformation effect, but there were no differences between intoxication levels: Intoxicated participants were not more susceptible to misinformation than sober or placebo participants. Results are discussed in the light of their theoretical and applied relevance.  相似文献
