The Internet of Things (IoT) as an emerging global Internet-based information architecture facilitating the exchange of goods and services is gradually developing. While the technical aspects are being discussed in detail a legal framework does not exist so far. The first supranational organization trying to work out an IoT governance framework has been the European Commission by appointing a large group of experts to examine the relevant aspects of a possible IoT governance regime. In the meantime, however, the activities have been degraded. Nevertheless, even if the differences between the IoT and the Internet have been overestimated at the beginning, many elements of the IoT differ in part from the corresponding problems in the Internet. Therefore, an analysis of the major IoT governance issues (legitimacy, transparency, accountability, anticompetitive behavior) seems to be worthwhile to conduct.  相似文献

This article analyses digital identity as an emergent legal concept in the United States of America, as a consequence of the move to place all federal government services on-line. The features and functions of digital identity and its legal nature are examined, and the consequences are considered.  相似文献

New technologies permit online businesses to reduce expenses and increase efficiency by, for example, storing information in “the cloud”, engaging in online tracking and targeted advertising, location and tracking technologies, and biometrics. However, the potential for technology to facilitate long term retention of customers' personal information raises concerns about the competing right of individuals to the privacy of their personal information. Although the European Commission has recently released a proposal for regulation to “provide a data subject with the right to be forgotten and to erasure”, neither the OECD Privacy Guidelines nor the APEC Privacy Framework includes any requirement to delete personal information. While New Zealand includes a “limited retention principle” in the Privacy Act 1993, apart from one limited exception the privacy principles cannot be enforced in court. Taking New Zealand privacy law as an example, this paper examines the issue of retention of customer data, explains why this is a serious problem and argues that although it could be addressed by appropriate amendments to domestic laws, domestic privacy legislation may not be sufficient in an online environment. In the same way as other areas of law, such as the intellectual property regime, have turned to global regulatory standards which reflect the international nature of their subject matter, international privacy regulation should be the next stage for the information privacy regime.  相似文献

In this contribution, the authors explore the differences and interplays between the rights to privacy and data protection. They describe the two rights and come to the conclusion that they differ both formally and substantially, though overlaps are not to be excluded. Given these different yet not mutually exclusive scopes they then apply the rights to three case-studies (body-scanners, human enhancement technologies, genome sequencing), highlighting in each case potential legal differences concerning the scope of the rights, the role of consent, and the meaning of the proportionality test. Finally, and on the basis of these cases, the authors propose paths for articulating the two rights using the qualitative and quantitative thresholds of the two rights, which leads them to rethink the relationship between privacy and data protection, and ultimately, the status of data protection as a fundamental right.  相似文献

Summer schools in law are a common feature of Irish legal education today. Originating in the US, summer schools are now an international phenomenon. In 2005, the eLaw Summer Institute (or ELSI), was established at University College Cork as a four-week international summer school. In this article, we reflect on the design and development of ELSI, with reference to three key aspects of this summer school. First, we address issues arising from the intensive teaching aspect of ELSI, including the use of technology as part of a blended learning experience. Second, we explore the challenges posed by the international audience in ELSI. Lastly, we critically examine the comparative elements of the school in terms of curriculum design and delivery of the programme. Our analysis builds upon existing literature in the areas of curriculum design and delivery, intensive teaching, the international classroom and comparative legal studies; and is informed by empirical data in the form of anonymous student questionnaires. The aim of the article is to engage with others involved in summer programmes, to share our experiences and critical analysis and to provide an insight for those not involved in summer school programmes into the challenges and the rewards for students, staff and the institutions involved.  相似文献

This paper examines the relationships between alcohol outlet density, alcohol use, and perpetration of intimate partner violence (IPV) among young adult women in the US. Data were from Wave III of the National Longitudinal Study of Adolescent Health (Add Health; N?=?4,430 in present analyses). Multinomial logistic regression was used to examine occurrence of past year IPV perpetration toward a male partner based on tract-level on-premise and off-premise alcohol outlet density, controlling for individuals’ demographic, alcohol use, and childhood abuse characteristics and neighborhood socio-demographic factors. Higher off-premise alcohol outlet density was found to be associated with young women’s perpetration of physical only IPV, controlling for individual-level and ecological factors. Alcohol use had an independent association with IPV perpetration but was not a mediator of the outlet density-IPV relationship. Findings suggest that considering alcohol-related environmental factors may help efforts aimed at preventing young women’s use of physical violence toward partners.  相似文献

In this study of perceived legitimacy, Australian citizens from a randomly selected national sample first responded to information about how judicial authorities responded to two crimes (green protest, date rape) in terms of seriousness and recommended punishment. They also provided ratings of the importance of a set of values for judicial authorities compared with self, and measures of global value discrepancy, procedural fairness, expertise, and legitimacy. Results showed that perceived legitimacy was negatively related to global value discrepancy and that the information provided to participants about judge’s position primed differences in value discrepancy only for the date rape crime. Other findings also implied that the nature of the offense moderated legitimacy/value discrepancy relations. Perceived legitimacy was also positively related to procedural fairness and the expertise of the authority, and higher when the judicial authority was perceived to assign specific values as even more important than participants did themselves.  相似文献

Objectives

The logic of incapacitation is the prevention of crime via the forced removal of known offenders from the community. The challenge is to provide a plausible estimate of how many crimes an incarcerated individual would have committed, were s/he free in the community rather than confined in prison. The objective of this study is to provide estimates of the incapacitation effect of first-time imprisonment from a sample of convicted offenders.

Methods

The data are official criminal records of all individuals convicted in The Netherlands in 1997. Two different analytical strategies are used to estimate an incapacitation effect. First, the offending rate of the imprisoned individuals prior to their confinement in 1997 provides a “within-person counterfactual”. Second, imprisoned offenders are paired with comparable non-imprisoned offenders using the method of propensity score matching in order to estimate a “between-person counterfactual”. Incapacitation estimates are provided separately for juvenile imprisonment (ages 12–17) as well as adult imprisonment (ages 18–50), and for male and female offenders.

Results

The best estimate is that 1 year of incarceration prevents between 0.17 and 0.21 convictions per year. The use of additional data sources indicates that this corresponds to between roughly 2.0 and 2.5 criminal offenses recorded by the police.

Conclusions

The current results suggest that, insofar as imprisonment is used with the primary goal of reducing crime through incapacitation, a general increase in the use of incarceration as the sanction of choice is not likely to yield major crime control benefits.  相似文献

Children in the United States are exposed to alarmingly high rates of violence and trauma. Notable are the rates of maltreatment among children and the heightened risk for both out of home placement and an array of developmental, behavioral, and psychosocial sequelae. Despite these risks, little information is available on effective interventions and services designed to address the complex needs of youth in residential treatment settings. To effectively respond to their unique developmental, behavioral, and emotional needs, trauma-informed interventions and services must be provided to support optimal outcomes. To this end, this paper delineates the prevalence of children in residential care secondary to chronic maltreatment and other trauma exposures, identifies behavioral and emotional issues through the theoretical framework of complex trauma, highlights the importance of organizational capacity to deliver trauma-informed services, and describes effective clinical interventions that are often used in residential treatment. Clinical considerations and recommendations are also provided.  相似文献
