Carnivore is a surveillance technology, a software program housed in a computer unit, which is installed by properly authorized FBI agents on a particular Internet Service Provider’s (ISP) network. The Carnivore software system is used together with a tap on the ISP’s network to “intercept, filter, seize and decipher digital communications on the Internet”. The system is described as a “specialized network analyzer” that works by “sniffing” a network and copying and storing a warranted subset of its traffic. In the FBI’s own words “Carnivore chews on all data on the network, but it only actually eats the information authorized by a court order”. This article, in two parts, will provide an overview of the FBI’s Carnivore electronic surveillance system. The Carnivore software’s evolution, its ‘prey’ and the system’s relationship with Internet Service Providers will be the focus of the study. (Although the FBI’s Carnivore surveillance system is now officially called DCS1000, as the surveillance system is more commonly referred to as “Carnivore”, that term will be used throughout). Also addressed in the article are misconceptions about Carnivore, publicly available sniffer programs, Carnivore’s functionality, methods to counter Carnivore as well as the software’s limitations. In addition, the pertinent American law allowing for wiretapping and electronic surveillance as well as programs and policies outside the United States regarding electronic surveillance are surveyed, and an overview of ECHELON, the global interception and relay system, is provided. The aim is to provide the paper’s readers with a better understanding of these surveillance systems: naturally, only through an in-depth knowledge can the benefits and dangers they present for the public (government), private (individual communications users) and technical industry (ISPs) be understood.  相似文献

Objectives

Informed by situational crime prevention (SCP) this study evaluates the effectiveness of the “West Bank Barrier” that the Israeli government began to construct in 2002 in order to prevent suicide bombing attacks.

Methods

Drawing on crime wave models of past SCP research, the study uses a time series of terrorist attacks and fatalities and their location in respect to the Barrier, which was constructed in different sections over different periods of time, between 1999 and 2011.

Results

The Barrier together with associated security activities was effective in preventing suicide bombings and other attacks and fatalities with little if any apparent displacement. Changes in terrorist behavior likely resulted from the construction of the Barrier, not from other external factors or events.

Conclusions

In some locations, terrorists adapted to changed circumstances by committing more opportunistic attacks that require less planning. Fatalities and attacks were also reduced on the Palestinian side of the Barrier, producing an expected “diffusion of benefits” though the amount of reduction was considerably more than in past SCP studies. The defensive roles of the Barrier and offensive opportunities it presents, are identified as possible explanations. The study highlights the importance of SCP in crime and counter-terrorism policy.

Based on London's theoretical model, results of a developmental study of Israeli children from four subcultures are reported. The impact of child-rearing practices on achievement motivation, hypnotic susceptibility, and brain wave patterns of subjects from Eastern European, Kurdish, Yemenite, and Moroccan backgrounds was tested and compared according to age level. Subjects were 15 children from each subcultural group. Five in each subcultural group were between 7 and 9 years old, five between 9 and 11, and five between 11 and 13. Instruments included a combined EEG-hypnotic scale, six measures of achievement and nAch, and the Winterbottom questionnaire. Subjects of European background, presumably with the highest nAch, had the lowest mean score in hypnotic susceptibility, while children of Moroccan descent, presumably the lowest achievement group, had the highest mean susceptibility score among the four subgroups as expected. It was also found, consistent with previous developmental studies of American children, that hypnotic susceptibility increases significantly with age regardless of subcultural grouping. While the four subgroups differed significantly in their school performance as expected, they did not differ in their need achievement scores. Findings in regard to EEG data are presently not reported because of technical difficulties encountered during recording. Implications for future research pertaining to methodological and theoretical issues involved in testing the model cross-culturally are discussed.This research was supported by the research committee of the Paul Baerwald School of Social Work of the Hebrew University of Jerusalem, Israel, and by National Institute of Mental Health Grant No. 53-4873-6748.Received B.A. from the Hebrew University of Jerusalem, M.S.W. from New York University, and doctorate and subsequent postdoctoral training from the University of California, Berkeley.

In this paper I discuss the four Women and Labour conferences which were held in Australian capital cities over the seven years between 1978 and 1984. I explore the ways in which the history of Australian feminist activism during this period could be written, questioning in particular the claim that the Women and Labour conferences have been central to the history of Australian feminism. I discuss the ways in which a historical sense could be established, using writings about the conferences as historical ‘evidence’, that race and ethnic divisions between women had not been important to the ‘women's movement’ until 1984. In other words, I challenge the construction of this conference as a turning point - not only in the feminist politicization of immigrant and Aboriginal women, but also in the politicization of all feminists about race and ethnic divisions. More broadly, I am interested in how a history would be written if it aimed to get to the ‘truth’ about racism and about the feminist activism of immigrant women. How would the apparent lack of written ‘evidence’ - at least until 1984 - of immigrant women's feminist activism, and of the awareness of Australian feminists about issues of racism, be written into this history? In addition, I suggest that it is important to the writing of feminist history in Australia that published documentation has been mostly produced by anglo women, and is thus partial and mediated by the lived, embodied experiences of anglo women. Finally, my intention is to interrogate commonly understood narratives about Australian feminist history, to challenge their seamlessness, and to suggest the importance of recognizing the tension within feminist discourses between difference as benign diversity and difference as disruption.  相似文献

This study examines the relationship between public service motivation and antecedents believed to be important determinants of moral commitment. Research conducted during the past decade indicates that public service motivation is a valid construct that is useful for predicting outcomes that are important to public organizations and to society. The sample for the empirical study consists of winners of the Daily Point of Light Award and the President's Community Volunteer Award. Antecedents studied are volunteer experience, religious activity, and parental socialization. Quantitative and qualitative analyses are used to identify key determinants of public sector motivation. Religious activity is positively related to formal and informal volunteering. Interviews strongly support the quantitative findings, especially the importance of religion, but also highlight the role of life-changing events.  相似文献

The case of post-Dayton Bosnia and Herzegovina (BiH) provides an interesting lens through which to reflect on the interconnected and often conflicting challenges of implementation of internationally brokered peace agreements, external support to democratic transition and consolidation, and contemporary notions of sovereignty and state building. This chapter suggests that in the case of BiH, certain contradictions and tradeoffs have been and may still be necessary to ensure a foundation for future stability and democratic consolidation. The situation in post-Dayton BiH can be described as a frozen conflict that has remained frozen in large part due to an international presence that ensures that an imperfect peace prevails while also providing a basis for incremental reform. The peace implementation process in BiH is briefly reviewed by looking at two reform strategies: the “soft” protectorate strategy used in BiH as a whole and the “hard” protectorate option exercised in the District of Brčko. The aim is to demonstrate that while a democratic end-state remains the goal in such transitions, the means toward getting there can include a number of contradictory policy options.

Community college completion rates are low, especially among low-income students. The existing policy and research attention has primarily focused on academic and financial challenges, but there is ample reason to think that non-academic obstacles might be key drivers of dropout rates for low-income students. This study focuses on the role of “life barriers” and investigates the effectiveness of intensive case-management services for low-income community college students. We evaluate the impact of the Stay the Course (STC) intensive case-management program through a multi-armed randomized controlled trial evaluation conducted between 2013 and 2016 in Fort Worth, Texas. Analysis of administrative records indicates that STC significantly increased persistence and degree completion for women; estimates for the full sample are imprecise. The statistically significant estimates for women imply that STC tripled associate's degree receipt by 31.5 percentage points. We find no difference in outcomes between students in an emergency financial assistance (EFA) only treatment arm and the control group. Given program costs of $4,343 per person, the implied cost per additional associate's degree is $27,140. This study complements existing literature on financial and informational interventions designed to increase completion rates and is most closely related to the smaller literature examining coaching and mentoring interventions.  相似文献
