Using stochastic methods we illustrate that the Provisional Irish Republican Army's (PIRA) network is clustered along three primary dimensions: (a) brigade affiliation, (b) whether the member participated in violent activities, and (c) task/role within PIRA. While most brigades tended to foster connections within the brigade (that is, “closure”), the tendency to do so varied across the organization. Members who engaged with violent activities were far more likely to connect with each other; in later periods there is polarization into those who engage in violent activities and those who do not. Across brigades, those who engage in a particular task and role (improvised explosive device [IED] constructor, IED planter, gunman, robber/kidnapper/drug smuggler/hijacker) are more likely to connect with others who do the same task or play the same role than with other members who fulfill other roles. Standard forms of homophily (that is, the tendency to make connections with people who are similar in terms of demography or status) play a very weak role in explaining which members interact with one another. Finally, our analysis illustrates clear patterns of relational change that correspond to changes in the formal structures that PIRA's leadership promoted. 相似文献

The articles in this special issue are drawn from papers presented at a conference titled Critical Terrorism Studies: Practice, Limits and Experience. The conference was organised by the Critical Studies on Terrorism Working Group of the British International Studies Association (BISA). The event was supported by both a BISA workshop grant and by Loughborough University’s Centre for the Study of International Governance (CSIG) and was held at Loughborough University from 9–10 September 2013. The conference aimed to explore what we know about terrorism and counterterrorism and importantly to ask how we know it. Reflecting the recent “materialist”, “everyday”, “experiential” and “narrative” turns in the fields of International Relations (IR), Geography and Cultural Theory, the event brought together scholars and practitioners to reflect on practices of research and knowledge production in Critical Terrorism Studies and related fields. The articles in this special issue reflect those aims. 相似文献

Questioned documents examined in a forensic laboratory sometimes contain signatures written with ballpoint pen inks; these signatures were examined to assess the feasibility of micro‐attenuated total reflectance (ATR) Fourier transform infrared (FTIR) spectroscopy as a forensic tool. Micro‐ATR FTIR spectra for signatures written with 63 ballpoint pens available commercially in Korea were obtained and used to construct an FTIR spectral database. A library‐searching program was utilized to identify the manufacturer, blend, and model of each black ballpoint pen ink based upon their FTIR peak intensities, positions, and patterns in the spectral database. This FTIR technique was also successfully used in determining the sequence of homogeneous line intersections from the crossing lines of two ballpoint pen signatures. We have demonstrated with a set of sample documents that micro‐ATR FTIR is a viable nondestructive analytical method that can be used to identify the origin of the ballpoint pen ink used to mark signatures. 相似文献

Ectodermal dysplasia comprises a group of disorders affecting ectodermal tissues. Severity depends on the genetic aberration; hyperpyrexia secondary to absence of sweat glands is a common complication. Treatment is supportive. This case report describes a 1‐month, 27‐day‐old male infant with a diagnosis of X‐linked recessive anhidrotic ectodermal dysplasia. On the day of his death, his mother swaddled him in a blanket and placed him on the couch at 5:30 am. When she picked him up at 8:00 am, he was unresponsive. At the emergency department, his rectal temperature was 40°C. Postmortem blood culture was positive for group B streptococcus, a possible etiology for fever. It is vital to teach parents that close monitoring of children with ectodermal dysplasia is necessary, as an increase in body temperature can become life threatening. 相似文献

This study tests the three hypotheses derived from the written opinion of Justice Thurgood Marshall in Furman v Georgia in 1972. Subjects completed questionnaires at the beginning and the end of the fall a semester. Experimental group subjects were enrolled in a death penalty class, while control group subjects were enrolled in another criminal justice class. The death penalty class was the experimental stimulus. Findings provided strong support for the first and third hypotheses, i.e., subjects were generally lacking in death penalty knowledge before the experimental stimulus, and death penalty proponents who scored “high” on a retribution index did not change their death penalty opinions despite exposure to death penalty knowledge. Marshall’s second hypothesis--that death penalty knowledge and death penalty support were inversely related--was not supported by the data. Two unexpected findings were that death penalty proponents who scored “low” on a retribution index also did not change their death penalty opinions after becoming more informed about the subject, and that death penalty knowledge did not alter subjects’ initial retributive positions. Suggestions for future research are provided. 相似文献

AbstractOne key marker of mass social movements transitioning to participatory democratic governance is popular media access. This essay argues that democratic media access by public constituencies becomes a site for constructing social revolution and simultaneously a manifest empirical measure of the extent of democratic participation in the production, distribution, and use of communication with new cultural possibilities. The participatory production practices (with citizens producing and hosting their own programs) and the democratic content (of oral histories, local issues, critiques of government and business, and everyday vernacular) reflect the hegemony of emerging ‘Bolivarian’ twenty-first century socialism expressed as popular participation in media production. Bolstered by constitutional changes and public funding, popular social movements of civil society, indigenous, women, and working class organizations have gained revolutionary ground by securing in practice the right of media production. Findings indicate that public and community media (that move beyond alternative sites of local expression and concerns) provide a startling revolutionary contrast to the commercial media operations in every nation. Popular media constructions suggest a new radically democratic cultural hegemony based on human solidarity with collective, participatory decision-making and cooperation offering real possibilities and experiences for increased equality and social justice. 相似文献

Gender inequality has been empirically linked to the incidence of terrorism, as a motivator for women’s involvement in terrorism, and political and social violence more generally. Although these studies demonstrate that advances in gender equality on average decrease terrorism, it is unclear how these influences translate to individual nations or conflicts. Because Turkey has witnessed consistent but unequal regional advances in gender equality, it provides an ideal setting to examine how these developments have influenced terrorist violence. Analyzing data from Turkey’s 81 provinces from 2000–2013, this study finds important regional differences in the influence of gender equality on terrorism. 相似文献

AbstractBuilding on studies on the political business cycle, the literature on welfare state retrenchment has argued that governments which cut the welfare state try to avoid blame by implementing painful measures in the beginning of the mandate and expanding benefits as elections approach. In contrast to this linear relationship, this article argues that governments often feel pressured to fulfil (mostly expansionary) campaign promises during the first months in office. Consequently, cutting right away is not what should be expected. Instead, a more nuanced, U-shaped timing trajectory is probable with a period in the beginning characterised by both cuts and fulfilment of expansionary pledges, followed by a period of cutbacks, and finally an expansive phase towards the end of a mandate. This argument is tested on our new original dataset of legislative changes in five European countries – Britain, Denmark, Finland, France and Germany – during the last four decades. 相似文献

Lipstick can be an important piece of evidence in crimes like murders, rapes, and suicides. Due to its prevalence, it can be an important corroborative evidence in crime reconstruction. The analysis of such evidence can provide an evidentiary link between the suspect, the victim, object, or the crime scene. We report the use of nondestructive ATR-FTIR spectroscopy combined with chemometrics for the classification of 10 brands of lipsticks with nine samples each. Chemometric method of partial least square-discriminant analysis (PLS-DA) has been employed to interpret the data and classify the samples into their respective classes. The PLS-DA model provides an AUC figure above 0.99 in all brands except one; for which it is slightly less at 0.94. We have also tested the traces of these lipstick samples on different substrates treating them as unknowns in the already trained PLS-DA model. 100% of the samples on nine substrates viz. a cotton, nylon, plastic, dry tissue, denim (blue jeans), wet tissue, nitrile gloves, white paper, and polyester were correctly attributed to their source brand. In conclusion, the results suggest that ATR-FTIR combined with the chemometrics is a rapid, nondestructive, and accurate method for the discrimination and source attribution of lipstick. This study has potential for use in actual forensic casework conditions. 相似文献
