This paper looks at EU banks' use of public cloud computing services. It is based primarily on anonymised interviews with banks, cloud providers, advisers, and financial services regulators. The findings are presented in three parts. Part 1 of this paper explored the extent to which banks operating in the EU, including global banks, use public cloud computing services. Part 2 of this paper covered the main legal and regulatory issues that may affect banks' use of cloud services.Part 3 looks at the key contractual issues that arise in negotiations between banks and cloud service providers, including data protection requirements, complexities caused by the layering of cloud services, termination, service changes, and liability. It also presents the overall conclusion derived from the studies conducted, as set out in the three parts of the paper.All three parts of the paper can be accessed via Computer Law and Security Review's page on ScienceDirect at: http://www.sciencedirect.com/science/journal/02673649?sdc=2. The full list of sources is available via the same link and will be printed at the end of this part of the article. 相似文献

Scholarship has focused on the use of license plate readers by patrol officers as a rational instrument for accomplishing key policing goals, including recovering stolen vehicles. In contrast, this paper applies the theoretical framework of innovation reinvention to explain how license plate readers are being used by criminal investigators in more novel ways. This perspective provides insights into the practical benefits of an enhanced version of this technology. More significantly, it helps illuminate the innovation attributes and the organizational determinants that contribute to its adaptation. In our case study of an agency with extensive deployment of license plate readers, we found that factors contributing to their reinvention included their widespread availability and compatibility with other information systems, their lack of complexity, the characteristics of their users, and the role of leadership in promoting their use. These findings have implications for advancing knowledge about the complex nature of the innovation process. 相似文献

Jurisdictions at every level throughout the U.S. are paying an increasing amount of attention to pretrial case processing. The primary areas of attention appear to be on risk assessment development and classification, the effects of pretrial detention, and the effectiveness of various strategies that may impact a defendant’s failure to appear for their assigned court dates. The current study is a randomized experimental trial designed to test the effects of court notification strategies, using failure to appear (FTA) as the primary outcome of interest. Our findings do not reveal a palpable effect for court notification strategies (telephone calls, and text messaging, with other conditions layered in), but do indicate and reinforce the utility of an actuarial method of risk classification when predicting likelihood of FTA. 相似文献

Cystic fibrosis (CF) is a lethal genetic disease, yet improved care has extended the mean age of survival into the young adult years. Many of the surviving adolescents have respiratory and digestive problems which delay growth and sexual development. It has been suggested that the specter of fatal disease interferes with adjustment to adolescence. We administered the Offer Self-Image Questionnaire to three groups with mean height less than the fifth percentile: CF males aged 12–19 (n=16); CF females aged 12–19 (n=8); and otherwise healthy males with short stature and/or delayed puberty aged 13–19 (n=34). The values obtained were compared to published normative data for a large number of normal adolescents and a smaller number of adolescents actively undergoing treatment for emotional disorders. CF males showed an abnormal pattern of adjustment that could be considered comparable to disturbed males and to growth-delayed and sexually delayed males. The CF female group was concordant with the normal population, rather than with the emotionally disturbed population. Thus CF and pubertally delayed males have a self-perception of maladjustment to the psychologic problems of adolescence. This suggests that adjustment problems of the CF male may be related to growth retardation and pubertal delay, the social stigma of which may be more easily disguised in the female. This is important in health care, since recent evidence suggests that exemplary attention to medical compliance and nutrition may ameliorate some of the growth lag both in pubertal delay and CF.Postdoctoral medical research fellow in allergy, immunology, and respiratory disease at Children's Hospital at Stanford.

Fifty known siblings and fifty unrelated pairs were genotyped using the ABI Identifiler STR system and sibship indices computed for each pair. Combined sibship indices (CSIs) for the known siblings ranged from less than 10 to greater than 1 billion. CSIs for the unrelated pairs ranged from 4.5 x 10(-8) to 0.12. In the known sibling group the percentage of loci where both alleles matched was approximately 40%, while the percentage of loci where neither matched was approximately 10%. In the non-sibling group, the percentage of loci where both alleles matched was approximately 6%, while the percentage of loci where neither matched was approximately 45%. Interestingly, the percentage of loci where a single allele matched was the same in both the known siblings and unrelated pairs, approximately 50%. 相似文献
