Abstract
Utilizing an interactionist perspective, two associated sensitizing constructs, and a combination of social psychological theory, this article reports on the influence of the peer group on individual perceptions, and its impact on initiation and persistence of bullying. The specific research question, "How does the need to conform with peers and the peer group influence the initiation and persistence of bullying others?" is investigated. Semistructured, one-on-one interviews with a purposive sample of 51 Grade 7 students (aged 12 years) were conducted during school time to investigate factors that influence students to bully others and what might help them to stop. Emerging from the theme of peer group was the need for belonging and group status, in particular social norms or the need to conform, which was influential when students described why they initiated and persisted with bullying others. The influence of labeling, the group process, and the aspiration to be like others within their group emerged as key constructs. The implications of these data for schools will be described and recommendations made.

Abstract
According to the most recent report of American Heart Association (AHA), heart disease, stroke and other cardiovascular diseases continue to remain not only the no.1 killer of Americans but also a major cause of permanent disability among American workers. Recently, many research efforts have been carried out to apply artificial intelligence (AI) to auscultation based method for rigorous detection/classification of heart murmurs but accuracy rates are not always high. All of the proposed AI techniques rely on converting the heart sound to an electrical signal and processing that signal to optimize the AI for murmur detection and classification. However, all these techniques fail to recognize that the electrical signal coming out of the cochlea is very different than the electrical signal coming out of the microphone or any other electrical sensor which is commonly used for converting heart sound to electrical signal. In this research paper, we want to take a novel approach to pre-process the electrical heart sound signal before it goes to AI for murmur detection/classification by altering the electrical signal in a similar way as is done by the human cochlea before sending the signals to the brain. Our hypothesis is that cochlea like pre-processing will change the spectral contents of the heart sound signal to enhance the murmur information which can then be efficiently detected and classified by AI circuitry. Using this approach, we plan to develop an AI based system for heart murmur classification/ detection with success rate comparable to that of an expert cardiologist.

Abstract
It is estimated that of 50,000 persons in Scotland (1% of the county's population), infected with the hepatitis C virus (HCV), around 90% injected drugs. This paper reviews data on the prevalence and incidence of HCV, and the methods used to generate such information, among injecting drug users (IDUs), in Scotland. The prevalence estimate for HCV among IDUs in Scotland as a whole (44% in 2000), is comparable with those observed in many European countries. Incidence rates ranged from 11.9 to 28.4/100 person-years. The data have shaped policy to prevent infection among IDUs and have informed predictions of the number of HCV-infected IDUs who will likely progress to, and require treatment and care for, severe HCV-related liver disease. Although harm reduction interventions, in particular needle and syringe exchanges and methadone maintenance therapy, reduced the transmission of HCV among IDUs during the early to mid-1990s, incidence in many parts of the country remains high. The prevention of HCV among IDUs continues to be one of Scotland's major public health challenges.

Abstract
The Internet is seen by many as a form of cyberspace or environment in which to interact and socialise. This research project drew from the data of a quantitative and qualitative study of gay men in Perth, Western Australia. We examined gay men's usage patterns of chat rooms and other social aspects of the Internet to meet sexual partners. We then reviewed in detail the meanings gay men have for the various Internet environments, and the range of friendship, relationship, casual, or esoteric sex-seeking goals. We argue that gay men view and engage with the Internet differently from how they view and engage with other more traditional gay spaces. This different approach influences how interaction between the men, either online or face-to-face, progresses and how assumptions and expectations are built. This has implications for how sexual health promotion interventions determine the appropriate role and relationship they have with these online social spaces.

Abstract
Recent evidence suggests that cell-free plasma DNA has potential use as a prognostic marker in many clinical settings. The aim of the present study was to evaluate the prognostic role of cell-free plasma DNA in the prediction of clinical outcome in intensive treatment unit (ITU) patients. Cell-free plasma DNA was measured by real-time polymerase chain reaction assay for the beta-globin gene and SOFA score, APACHE II score, CRP concentrations, and clinical outcome (duration of stay, ventilation time, and mortality) were noted in 94 patients on admission to the ITU. The median plasma DNA concentration in ITU patients was 5493 GE/mL and this was significantly (P <0.001) higher than the DNA concentration in healthy subjects (1970 GE/mL). DNA concentration demonstrated a significant correlation with serum C-reactive protein (CRP) (r = 0.363) concentration and Sepsis-related Organ Failure Assessment (SOFA) (r = 0.360) score (P <0.001 for both by Pearson correlation) but not with Acute Physiology And Chronic Health Evaluation (APACHE II) score. Patients on ventilation had significantly higher DNA concentrations compared to nonventilated patients (7362 GE/mL versus 4479 GE/mL; P = 0.004). The median DNA concentration in nonsurvivors was 9148 GE/mL, and this was 2.3-fold greater than that in survivors (3921 GE/ml, P <0.001). ROC analysis of the data indicated a sensitivity of 85% and a specificity of 80% when DNA concentration of 6109 GE/mL was taken as a predictor of death. The data suggest that cell-free plasma DNA concentration is potentially useful as a prognostic marker in ITU patients.

Abstract
OBJECTIVE To determine whether choice of colposcopy or six month cytological surveillance would be beneficial to women with mildly abnormal smears when compared with the national policy of six months surveillance in terms of psychological morbidity. DESIGN A randomised trial based on the Zelen design. SETTING A hospital-based research clinic. POPULATION Four hundred and seventy-six women who had had a recurrent borderline or mildly dyskaryotic smear on routine cervical screening in primary care. METHODS Women were randomised either to six months cytological surveillance or to make a choice between that or colposcopy and were followed up for 1 year. MAIN OUTCOME MEASURES The primary outcome measure was caseness (score >or=4) on the General Health Questionnaire at 12 months follow up. Other measures were the Spielberger State and Trait scores, default rates and cytology/colposcopy outcomes. RESULTS There was no significant difference between the arms for General Health Questionnaire (GHQ) scores and Spielberger State and Trait at 12 months. There was a significant reduction in psychometric morbidity between baseline and 12 months in both arms. Overall rates of default from the protocol were the same in both arms, but default that led to uncertain ascertainment of cervical pathology was greater in the no-choice arm. CONCLUSIONS This trial indicates that having choice did not impact favourably or harmfully on anxiety or feelings of wellbeing. If a patient is anxious, allowing the patient to choose immediate colposcopy may be preferable because it will improve ascertainment of underlying disease in a group who are more likely to default.

Abstract
To provide a comprehensive understanding of the epidemiology of hepatitis C virus (HCV) infection in Scotland, a database of all persons known to have been infected with HCV in Scotland was established. Non-identifying data, held on the computers and requests forms in Scotland's principal and confirmatory HCV testing laboratories, were entered onto a National Database at the Scottish Centre for Infection and Environmental Health. As at December 2001, records from 13,519 persons in Scotland known to have been infected with HCV had been entered on to the database (one in 378 of Scotland's population). Of the 13,519, 69% were male and 90% of the 9,092 for whom risk factor information was available had injected drugs; 37% were from Greater Glasgow. Fifty-six per cent of the 13,519 were diagnosed between 1998 and 2001; 1,727 (23%) of the new diagnoses from 1998 to 2001 were aged under 25 years. The data provide an insight into the epidemiology of HCV infection in Scotland. They support other data, which indicate that the current major risk factor for HCV in the country is injecting drug use.

Abstract
This study investigated health promotion efforts at international schools serving the education needs of expatriate communities abroad. Factors supporting the implementation of whole-school approaches to health promotion also were examined. Self-completed questionnaires were distributed by a combination of electronic and conventional mail. International school staff in 93 countries (n = 205) completed an adapted version of an instrument used for evaluating the Western Australian School Health Project (WASHP). This survey demonstrated usefulness of the WASHP instrument cross-culturally in a variety of school settings. The level of whole-school approaches to health promotion in the participating international schools varied but tended to be low. Demographic characteristics of schools were not associated with differences in the level of health promotion, with the exception school size. School organizational factors support implementation of health promotion programs.

Abstract
RadarSat and ERS Synthetic Aperture Radar (SAR) satellite data have been used for oil slick mapping as part of a systematic interpretative study of the offshore Canning Basin, as well as part of the northern Carnarvon Basin, extending from the inner shelf to the abyssal plain. These seepage data have been integrated with regional geological data, more than 12,000 km of reprocessed Airborne Laser Fluorosensor (ALF) survey data, seismic DHI indicators, water column geochemical sniffer data, potential field data, earthquake data and 2D Petromod basin modelling, to provide new insights into the region’s petroleum prospectivity and key exploration risk factors.From a prospectivity viewpoint, this study has highlighted several areas and processes. Firstly, it is clear that overpressure in the region is principally controlled by the thickness of the Tertiary carbonate wedge and we predict that overpressure may be present in parts of the deeper water Canning Basin. Secondly, the offshore Canning Basin contains a relatively low density of SAR-mapped oil slicks, though this appears to be due to a combination of factors, namely a paucity of vertical conduits for leakage, a predominantly condensate-prone charge and a small slick size.Significantly, several as-yet untested areas emerge from our observations. In the offshore Canning Basin, a 'window' exists in about 1,500–2,500 m of water, where the Triassic source rocks are particularly well placed for liquids generation. Morever, a large area in a radius some 20–80 km outboard of the Bedout High, also appears to have significant untested liquids potential, with respect to sourcing from the Triassic. The shallow section through this region contains a vast area with abundant seismically mapped gas chimneys and other seepage indicators, supporting the conclusions from the remote sensing and basin modelling of significant hydrocarbon charge in this region. Finally, the study indicates that liquids have been generated within the Palaeozoic section of the Bedout Sub-basin.

Abstract
We previously reported a continual decline in anti-HCV prevalence among young injectors from Glasgow and Lothian between 1990 and 1997. The original study was extended to ascertain if the anti-HCV prevalence among injectors from Glasgow, Lothian, Tayside and Grampian had changed since 1997. Residual sera from injectors who had undergone attributable anti-HIV testing were tested anonymously for anti-HCV. In all four regions, no significant changes in prevalence were found among those aged < 25 years during the late 1990s (Glasgow 1997-9/00: 43%-41%; Lothian 1997-9: 13%-17%; Tayside 1997-9: 45%-35%; Grampian 1996-9: 28%-29%). Among those aged > or = 25 years, significant decreases in prevalence were only observed in Glasgow (1997-9/00: 79%-72%, P = 0.03) and Lothian (1997-9: 54%-45%, P = 0.05). The findings highlight that existing harm reduction measures, acknowledged as having helped to reduce the spread of HCV, are not sufficient to bring this epidemic under control and reduce transmission to sporadic levels.
