Data gold mining

The Motorway Incident Detection and Automatic Signalling (MIDAS) system data are summaries of traffic volumes, speeds and vehicle types, derived from loop detectors that sense traffic passing over them. These sensors are being rolled out across the UK's strategic highway network (motorways and major A-roads) and data from portions of one of the busiest motorways, the M25, now go back 10 years. Richard Gibbens and Wiebke Werft describe a journey time predictor based on MIDAS and explain how the data can shed light on topical issues such as road pricing.     

Recursive politics: prevention,modernity and social systems

The aim of this paper is to connect the recent interest in prevention to recent developments in social theory. It begins by recovering some of prevention's essential features from the realm of common sense, showing that what is taken to be the common sense of prevention is emblematic of modernity. For prevention is built on scientific understandings of cause and effect and the possibility of prediction; on a capacity for controlled intervention by government in social life; on a universal value base; on the authority of professional expertise; on rational, calculating, individual social subjects. As this order develops and changes, many of its constituent elements begin to be threatened by social processes which it has itself set in train. Prevention is affected by (and implicated in) these changes, too. But far from being eclipsed by them it becomes more prominent. Drawing on systems theory, the paper argues that prevention meets the essential purpose of boundary maintenance by which the functioning of social systems is sustained. For reasons both external and internal to welfare agencies, including an increased burden of social risk and increasing organisational complexity, this need to mark and maintain system boundaries is ever more pressing. At the same time, at least part of the problem of the fragility of boundaries is attributable to attempts to maintain them. It is for this reason that preventive policy making can be described as recursive, or self-propelling. Copyright © 1999 John Wiley & Sons, Ltd.     

Habitat use and activity patterns of urban-dwelling javelina

In Arizona, conflicts between homeowners and urban-dwelling javelina (Tayassu tajacu) continued to increase. Human-javelina conflicts often occurred when javelina responded to urban attractants and destroyed ornamental landscapes, injured pets, and frightened homeowners. This prompted initiation of a study during 1992–93 to develop recommendations to alleviate these conflicts. We captured, radio-collared, and located eight javelina from six herds to determine home ranges, habitat use, and activity patterns in Prescott, Arizona. Urban-dwelling javelina adjusted their home ranges, habitat use, and activity patterns to best use human-provided urban food, water, and cover resources. The most conspicuous of these adjustments was the increased nocturnal activity of urban-dwelling javelina to avoid human disturbances. Undeveloped land within or adjacent to Prescott provided javelina with daytime bedding areas and nighttime travel corridors. We determined that this issue was more a people problem than it was a javelina problem. Thus, strategies to resolve the conflicts must target homeowners.     

Nonprofit organizations' use of the internet: A content analysis of communication trends on the internet sites of the philanthropy 400

To evaluate the current status of communication and fundraising strategies on the Internet, a stratified random sample of the Chronicle of Philanthropy's Philanthropy 400 was content‐analyzed in mid‐January 2005. Web sites were coded on variables identified in practitioner and scholarly literature on issues of accountability, fundraising practices, and interactive communication strategies. Chi‐square analysis found that the top nonprofit organizations included copies of their annual reports, organizational goals, and mission statements, while second‐tier organizations were more likely to use a sales approach by using e‐commerce technology and terminology to process online donations.     

Some properties of a linear combination CUSUM statistic for controlling a multivariate mean vector

We develop a class of new multivariate procedures for monitoring quality by detecting a change in the level of a multivariate process. Following the ideas of S.N. Roy, we first consider a linear combination statistic which results from projecting the multivariate observations onto a unit vector and then maximizing a selected univariate statistic over all directions.     

Assessment of Intimate Partner Violence by Child Welfare Services

The purpose of this study was to describe policy and practice with respect to the assessment of intimate partner violence in a sample of child welfare agencies located throughout the United States and to examine the relationship of contextual characteristics and assessment practices. Telephone interviews were conducted with key informants from child welfare agencies. A snowball interviewing strategy was used to identify the best informant in each agency. Almost all of the participating agencies conducted some assessment of intimate partner violence, with most reporting that the majority of screening or assessment occurred during investigation of referrals. However, only 43.1% reported that all of the families referred to the child welfare system were assessed for intimate partner violence, and 52.8% indicated they had a written policy pertaining to screening and assessment of the problem. There was little relationship between county or agency characteristics and assessment practices. Additional research is needed to determine factors that influence assessment practices and to identify strategies to support and extend efforts to identify intimate partner violence and provide appropriate services for families in the child welfare system.     

Linguistic Markers of Psychological State through Media Interviews: John Kerry and John Edwards in 2004, Al Gore in 2000

What can we learn about presidential candidates by examining their speech in natural conversation? In the present study, the television interviews from the 2004 Democratic presidential primary campaign of John Kerry ( N = 29) and John Edwards ( N = 34) were examined using linguistic analyses. Results indicate that Kerry and Edwards were similar in their use of positive emotion words, but that Kerry used significantly higher rates of negative emotion words than did Edwards. Comparisons with televised interviews of Al Gore from the 2000 presidential campaign ( N = 17) revealed striking similarities in the linguistic styles of Gore and Kerry. Gore's linguistic style overlapped considerably with that of Kerry on pronoun usage and many cognitive domains. This study points to how linguistic analyses can give us a clearer picture of how political candidates think, act, and feel.     

Ethical–aesthetic critique of moral organization: Inspirations from Michael Haneke's cinematic work

This paper looks at the work of the Austrian film-maker Michael Haneke as an inspiration for developing an ethical–aesthetic critique of organization. Haneke's practice of film-making is located in the tradition of an ‘ethical parrhesia’, the courageous and often dangerous ‘truth-telling’, which aims at the transformation of being. Haneke's approach is then illustrated with an analysis of his film The White Ribbon. This example is taken to illustrate an ethical critique of moral organization and for analysing strategies that seek to instigate the open-ended moral reflection. By discussing implications of this form of critique, the paper contributes to the development of a critical aesthetics of organization that seeks to open a reflexive space on how we are formed in social and organizational life, and at what costs.     

Infant Learning: Historical,Conceptual, and Methodological Challenges

Acquiring knowledge about the underlying structures of the environment presents a number of challenges for a naive learner. These challenges include the absence of reinforcement to guide learning, the presence of numerous information sources from which only a select few are relevant, and the uncertainty about when an underlying structure may have undergone a change. A crucial implication of these challenges is that the naive learner must make implicit decisions about when to generalize to novel inputs and when to restrict generalization because there are multiple underlying structures. An historical perspective on these challenges is presented, and some potential solutions are proposed.
