Since the mid-1990s, political parties around the world have been moving into cyberspace. During the early years, it was not evident that many of them had any clearly defi ned ideas about why the internet would prove useful, or how they should present themselves on it. As time has passed, however, a number of key uses for the new technology have emerged as well some common trends in parties' and candidates' website content and appearance. Paramount among those uses has been the increasing use of the World Wide Web (WWW) and email as electioneering tools. This paper aims to chart the development of so-called "cyber-campaigning" by political parties both in terms of what they are doing (supply side) and also how the electorate are responding (demand side). The two key questions that will be addressed are 1) whether the practice is adding anything new to parties' campaign practices, and 2) what difference, if any, it is making for voters. Does cyber-campaigning play a decisive role in terms of changing minds, if not hearts? The analysis covers developments in cyber-campaigning across a number of contexts but has particular emphasis on Europe, the US, and Australia. Beginning with an historical overview, we chart the rise of web campaigning since the mid-1990s in the US and then move to look at the academic research that has attempted to compare and contrast website content and quality and also explain the distribution of party and candidate sites. After identifying some of the key elements within the cyber-campaign tool box, and the factors that appear to promote its practice, we then turn to look at the audience for election websites and discuss the crucial issue of the extent to which having a website actually matters for parties. One obvious measure of success may be whether the site actually produces an increase in the electoral support for the party. However, using such a measure may present problems given that more than half of the electorate in most countries remains without access to the web. Perhaps cyber-campaigns benefi t parties and candidates in more subtle and diffuse ways? Would perhaps having an attractive and user friendly website contribute to a positive image of organisational competence, and more importantly, contemporary relevance?  相似文献

Deliberate self-harm patients who leave the acute hospital environment before the completion of psychiatric assessment have an increased risk of subsequent self-harm. We considered the available data on 50 premature self-discharges identified prospectively in a general hospital with a well-developed integrated-care pathway for self-harm patients, and compared them to a control group. The self-discharge group was found to be more likely to have attempted self-poisoning without alcohol intoxication or other forms or combinations of self-harm, and an absence of identifiable previous self-harm or prior contact with local specialist psychiatric services. The two groups showed no difference in age, sex, or area of residence based on community mental health team sectors. It is proposed that these findings indicate hypotheses for further studies of why people leave the hospital without adequate assessment, and how service design could be improved in order to help them.  相似文献

A case involving self-extraction of teeth linked to the abuse of gamma-hydroxybutyric acid (GHB) is reported. A 28-year-old woman and her 29-year-old boyfriend were discovered by paramedics following an extensive period of GHB use. The paramedics were alerted by a neighbor who had heard screaming from the house. On presentation to the accident and emergency department, it was noted that the female had 18 fresh extraction sockets visible intra-orally. At the scene, a mirror, a pair of pliers, and a bowl containing human teeth were found. Charges of assault were taken to the courts against the boyfriend who was subsequently acquitted. Odontological evidence centered on whether or not it was possible to self-extract the teeth using the pliers found. This case is the first to describe possible oral self-mutilation under the influence of GHB and odontologists should always consider self-injury as an explanation for intra- and perio-oral injuries of unknown origin.  相似文献

Cerebral palsy (CP) is a nonprogressive motor deficit present or sustained in the perinatal period. We reviewed the files of the Office of Chief Medical Examiner of the City of New York for the 1997-2001 interval seeking those with any mention of cerebral palsy. There were 26 such cases, including 18 natural deaths, three accidents, two homicides, two therapeutic complications, and one death classified as undetermined. Proper reporting and careful investigation of these deaths is required for accurate certification of cause and manner of death, as well as for adequate tracking of these deaths for public health purposes.  相似文献

An approach for generating DNA profiles when critical samples have been consumed and a power outage occurs during the polymerase chain reaction (PCR) amplification reaction is described. This study demonstrates that a complete and accurate DNA short tandem repeat profile can be obtained: (1) when single source DNA samples are amplified for 26, 27, or 28 cycles using the Profiler Plus and COfiler Amplification Kits after an interruption in amplification, (2) from mock samples when PCR amplification has been interrupted early (after five cycles) or late (after 18 cycles) and the sample is subjected to an additional round of amplification, even after incubation of the sample at room temperature overnight, and (3) from nonprobative casework samples interrupted after approximately 18 cycles of amplification, an overnight incubation at room temperature and subjected to one or two additional rounds of PCR amplification for approximately 26 total cycles. Samples interrupted before five completed cycles and subjected to additional PCR cycles yielded variable results.  相似文献

The professional and legal regulation of assisted reproductive technologies (ART) in Australia is a vast maze of intersecting laws and guidelines which place restrictions on the provision of services such as infertility treatment, surrogacy, sex selection for social reasons, donor insemination, pre-implantation diagnosis and human embryo research. This study investigated the application of these restrictions on clinical practice in New South Wales, a relatively unregulated State, and Victoria, a relatively highly regulated State. The results of the survey indicate that the range of ART services in Victorian clinics was far more limited than in New South Wales clinics. The Victorian clinics uniformly restricted access of single and lesbian women and did not offer social sex selection procedures. The New South Wales clinics adopted different polices regarding these services. It was found that restrictive laws governing "social" issues have a significant impact on the availability of ART services and some respondents seemed unclear about the nature of restrictions and laws relevant to their work. It was also found that "reproductive tourism" is prevalent and restrictions were circumnavigated by patients with assistance from clinics. It was concluded that more evidence is required to evaluate regulation in this field of medicine.  相似文献
