This article examines the impact of the new ICTs on the collection of covert intelligence and covert political actions undertaken by national intelligence agencies. It is argued that there exist two distinct doctrines in the literatures of intelligence and information warfare concerning the future relative importance of information from human sources ('agents') and technical methods (signal interception, overhead imagery and the emerging field of clandestine penetration of networked information systems). The arguments in favour of human and technical methods are examined in the context of information warfare techniques and technologies, as are covert action methods such as disinformation, disruptive action and 'cyber-sabotage'. Certain civil liberties implications of ICT-based strong encryption are also examined. The article concludes that what is required is a greater emphasis on integrating human and technical methods into a unified whole, especially where human methods can provide opportunities which can be further exploited by technical methods.  相似文献

Desert landscaping has become a dominant land cover type in arid US cities and often includes native plant species. Does replacement of native plant distribution in urban areas also reestablish ecological functioning characteristic of natural deserts? We compared ecological processes in three landscape types that are common to the metropolitan area of Phoenix, Arizona (USA): residential desert yards created from former lawns, Sonoran Desert preserves within the city, and Sonoran Desert preserves outside the city boundaries. Canopy cover, abundance of herbivorous insects, and soil properties (concentration of inorganic nitrogen (N), soil moisture and organic matter content, and water-holding capacity) were higher in residential desert yards than in native desert sites located both within and outside of the city. Furthermore, soil resources in desert yards were not organized around plant canopies, departing from the predictable resource island pattern that is characteristic of natural deserts. Intentional human manipulation and land use history accounts for these differences, while the urban environment contributes only subtly to soil N concentrations beneath plant canopies. While the use of desert landscaping may have important water conservation benefits, it does not help to mitigate the well-documented excess of reactive N within the Phoenix metropolitan area.  相似文献

It is known that many older people have difficulties in performing daily living activities such as cooking. These are due to the demands of the tasks and the changes in functional capabilities of the older people. This study examines cooking tasks performed by the aged that includes preparing and cooking meals, and storing kitchen tools in the kitchen. The objectives are to investigate the cooking difficulties encounter by older people and the safety concerning cooking tasks. This study focuses on individuals of age 65 years and above who can cook for themselves and/or family. Data were collected through observation, interviews, questionnaires and role play methods. The findings revealed that the common problems were due to the awkward body position where subjects had to bend down to take things from lower shelves, taking/storing things on higher shelves and cleaning the cooker. Moreover, the safety concerns were the layout of work centres (storage, cooker and sink), the use of cooker and opening packaging. It can be concluded that cooking difficulties are caused by inappropriate kitchen design and the decline of functional capabilities in older people.  相似文献

This paper presents a rare attempt to quantify the deterrent effect of anticartel policy. It develops a conceptual framework, which establishes the sort of information necessary for such quantification. This is then illustrated and calibrated by drawing upon existing literatures and using evidence from legal cartels to approximate what would be observed absent policy. Measuring impact by the proportion of all potential harm that is deterred, our best estimate is two‐thirds and, even on conservative assumptions, at least half of all harms (or seven times the detected harm) is deterred.

During recent years ‘disability hate crime’ has become a major political and criminal justice concern due to a number of high-profile murders in the United Kingdom. The aim of this article is to compare disability-motivated hate crimes with other hate crimes motivated by homophobic or racist bias. This study employs a quantitative methodology utilising data collected by the ARCH hate crime recording system over a 10-year period (2005–2015). The data findings illustrate a number of variations concerning incidents reported by disabled people regarding violence and threatening behaviour, when compared with incidents motivated by race/faith or homophobic bias.  相似文献

Children's reports about their play in middle childhood and the emotions they associate with play have received limited research attention. Using focus groups, this study asked 38 children in the UK about what, where and with whom they played. They were also asked how play made them feel. Children reported a wide range of play behaviours, with outdoor and traditional games being just as prominently mentioned as play with electronic devices. The emotional importance of play in middle childhood was apparent, with children associating play with strong positive emotions, and not being able to play with negative emotions and anxiety.  相似文献

This study was designed to test for specificity in the relationship between individual friendship provisions and adjustment across early adolescence. Using a narrative procedure, attachment (i.e., accessing care) and affiliation (i.e., forming cooperative partnerships) were found to be distinct functional themes organizing 293 adolescents’ (Mage = 13) internal representations of their best friendship across three annual measurement occasions. Longitudinal, cross‐lag analyses revealed a unique transactional relationship between friendship affiliation and greater social competence over time, controlling for friendship stability, maternal relationship quality, socioeconomic status, and gender. By contrast, friendship attachment predicted fewer subsequent internalizing symptoms from ages 14 to 15. Together, findings point to the importance of understanding individual differences in the content of adolescents’ internal representations of friendship.  相似文献

Gray M., Davies K., Butcher L. Finding the right connections: Peer support within a community‐based mental health service This article reports on a qualitative study that examined the organisational enablers and barriers to implementing peer support work in an Australian, rural, community‐based mental health service. Interviews with 19 peer and non‐peer staff were conducted to identify attitudes towards peer support and whether there were organisational values, practices and strategies that might support the implementation of peer support. The findings revealed that peer support workers were valued for their ability to build trusting connections with clients and to accept client choice in a non‐judgemental way. However, peer support workers tended to ‘fill service gaps’ within intensive, administrative case‐management environments. These findings highlight the importance of an organisational‐wide approach to integrating peer support, where the responsibilities for adopting new ways of working fall to all staff, not just the peer support workers themselves. Key Practitioner Message: ? Practitioners placed high value on the peer support workers on their teams due to their unique personalised engagement with clients; ? The roles of peer support workers were poorly understood by team members; ? Organisational integration of peer support principles could improve the way all staff engage with clients to reflect a recovery orientation.  相似文献

Universities are increasingly expected to demonstrate the wider societal impacts of academic research. Yet women management scholars were disproportionately under‐represented in leading impact cases in the UK's REF (Research Excellence Framework) 2014. An analysis of 395 REF impact cases for business and management studies with an identifiable lead author revealed that only 25 per cent were led by women, of which 54 per cent were sole authored. Based on 12 in‐depth interviews with women impact case writers, we use Acker's inequality regimes framework to understand invisible and socially constructed gendering of the UK's policy that is designed to evaluate research impact. In a knowledge‐intensive workplace dominated by men, the shape and degree of gendered bases of inequality, systemic practices, processes and controls result in sub‐optimal talent management and gendered knowledge. We call for university leaders to be proactive in addressing barriers that fail to support or recognize women's leadership of research impact.  相似文献

Faculties at historically Black colleges and universities (HBCU) have demonstrated stellar contributions to social work, which include early thought and epistemology related to strengths, empowerment, and social justice perspectives; religious orientation; inclusive learning environment, and community-based research. W. E. B. DuBois was the most influential among these HBCU scholars; however, the DuBoisian tradition of scholar as activist must include works of Frazier, Haynes, Young, and others, who fueled discourse on contemporary social problems despite prejudice, discrimination, and Jim Crow. HBCUs provided direction for services to the new Black urban class when the profession was not prepared to do so. They led the profession to use new theoretical ideas, perspectives, and service modes for a new clientele.  相似文献
