Abstract
In the style of radio programmes, we developed three episodes of audio HIV prevention education for illiterate women in Ethiopia. We used social-oriented presentation formats, such as discussion between women on HIV prevention, and expert-oriented presentation formats, such as an interview with a male doctor. The aim of this study was to assess the relation between evaluation of presentation formats and overall liking of episodes, which is important for persuasive effects. Thirty women from rural Amhara listened to the episodes and, after listening, female data collectors interviewed the women on evaluation of presentation formats, overall liking of episodes, identification with the characters and convincingness. Evaluation of social-oriented presentation formats was strongly related to overall liking of episodes, but evaluation of expert-oriented presentation formats was not. This relation was mediated through convincingness and not through identification. We conclude that social-oriented presentation formats make messages more convincing and, consequently, improve overall liking and persuasive impact.

Abstract
Optical wireless links can offer a very large bandwidth and can act as a complementary technology to radiofrequency links. Optical components nowadays are however rather bulky. Therefore, we have investigated the potential of silicon photonics to fabricated integrated components for wireless optical communication. This paper presents a two-dimensional phased array antenna consisting of grating couplers that couple light off-chip. Wavelength steering of $0.24 degrees /nm is presented reducing the need of active phase modulators. The needed steering range is $1.5 degrees . The 3dB angular coverage range of these antennas is about $0.007pi sr with a directivity of more than 38dBi and antenna losses smaller than 3dB.

Abstract
This research examines the impact of a Spanish language mass media campaign on living organ donation attitudes and behavioral intentions among Spanish dominant Hispanics in Tucson, Arizona. Impact was assessed via a pretest/posttest control group quasiexperimental design with Tucson, Arizona, as the intervention community and Phoenix, Arizona, as the control. Preintervention focus groups provided qualitative data to guide intervention development, while telephone surveys in both communities provided quantitative data to assess campaign impact. Analyses reveal pretest/posttest differences in the intervention community such that posttest intentions regarding living organ donation behaviors increased from pretest. No such differences were observed in the control community. Subsequent analyses revealed differences between respondents in the intervention community exposed to the campaign vs. those in the same community not exposed to the campaign. Exposed respondents reported more positive living organ donation behavioral intentions than nonexposed respondents. Implications for research and practice are discussed.

Abstract
Neotropical orchid bees (Euglossini) are often cited as classic examples of trapline-foragers with potentially extensive foraging ranges. If long-distance movements are habitual, rare plants in widely scattered locations may benefit from euglossine pollination services. Here we report the first successful use of micro radio telemetry to track the movement of an insect pollinator in a complex and forested environment. Our results indicate that individual male orchid bees (Exaerete frontalis) habitually use large rainforest areas (at least 42-115 ha) on a daily basis. Aerial telemetry located individuals up to 5 km away from their core areas, and bees were often stationary, for variable periods, between flights to successive localities. These data suggest a higher degree of site fidelity than what may be expected in a free living male bee, and has implications for our understanding of biological activity patterns and the evolution of forest pollinators.

Abstract
We propose wireless sensor networks composed of nodes using low-power 802.15.4 radios as an enabling technology for patient monitoring in general hospital wards. A key challenge for such applications is to reliably deliver sensor data from mobile patients. We propose a monitoring system with two types of nodes: patient nodes equipped with wireless pulse oximeters and relays nodes used to route data to a base station. A reliability analysis of data collection from mobile users shows that mobility leads to packet losses exceeding 30%. The majority of packet losses occur between the mobile subjects and the first-hop relays. Based on this insight we developed the Dynamic Relay Association Protocol (DRAP), an effective mechanism for discovering the right relays for patient nodes. DRAP enables highly reliable data collection from mobile subjects. Empirical evaluation showed that DRAP delivered at least 96% of data from multiple users. Our results demonstrate the feasibility of wireless sensor networks for real-time clinical monitoring.

Abstract
OBJECTIVE In 2005, in terms of seat belt usage rates, Nevada ranked third nationally and first among states with secondary seat belt use enforcement laws in the United States. An effective combination of a media-based education and enforcement campaign helped in this regard. The objective of this article is to document the effectiveness of enforcement and media-based education and outreach campaigns on the seat belt usage rates in Nevada, a state with a secondary seat belt usage law. METHODS Observational data on seat belt usage and passenger fatality data are used to evaluate the effectiveness of enforcement campaigns and media-based education and outreach campaigns. Data based on observations of about 40,000 vehicles in each of the years 2003 to 2005 were analyzed. RESULTS Statistical analyses show that a significant increase in seat belt usage rates among both drivers and passengers for both genders resulted from the accompanying the media and enforcement campaigns. CONCLUSIONS The results from this study indicate that effective and well-planned media/enforcement campaigns can have a significant impact on seat belt usage rates even in a state where the enforcement of seat belt laws can only be as a secondary violation. They validate and expand on findings from other efforts documented in the literature. These results demonstrate that, if coordinated properly, media and enforcement campaigns work very effectively in increasing seat belt usage rates even in states with secondary seat belt laws.

Abstract
In this study 27 future professional voice users (i.e., radio students) and 53 professional voice users (i.e., radio professionals) were questioned on their vocal hygiene. Both groups differed clearly in age and in radio experience. The mean age of the radio students was 22 years, whereas the mean age of the radio professionals was 41 years; radio students had no radio experience and radio professionals' experience ranged from 2 to 32 years. This study shows that the vocal hygiene of radio professionals is not superior to the vocal hygiene of radio students. On the contrary, every group has a distinctive vocal hygiene profile. The intake of coffee was significantly higher in radio professionals (p < 0.001) and they indicated significantly more vocal fatigue (p = 0.028). The radio students, on the other hand, experienced more acid reflux problems (p < 0.001) and signalled significantly more hoarseness (p = 0.012). Next to this, both groups smoked more than one could expect from (future) professional voice users (radio students: 33%; radio professionals: 28%). This study demonstrates the necessity of an adapted vocal hygiene education programme for both future and professional voice users, as they seem to underestimate the negative implications of bad vocal hygiene.

Abstract
Hearing healthcare professionals often express concern about the possible increased risk of noise injury, and potential for subsequent hearing loss that may result from the rise in the use of personal stereo players (PSP) in the community. Measurements were made of a sample of 55 individuals who were using a PSP as part of their daily activity, for example commuting to work, in what could be considered noisy backgrounds. Thus measurements could be considered to exemplify the worst-case conditions. The average, A-weighted, eight-hour equivalent, continuous noise exposure level was determined to be 79.8 dB, with a statistically significant difference between males and females, of 80.6 dB and 75.3 dB respectively. There was no correlation between self-reported hearing loss and/or the incidence of tinnitus. The noise exposure results obtained did not indicate that there was a significant increase in the risk to potential noise injury from PSP use alone.

Abstract
BACKGROUND AND OBJECTIVES Radio frequency identification (RFID) can be a key enabler for enhancing productivity and safety of the blood product supply chain. This article describes a systematic approach developed by the RFID Blood Consortium for a comprehensive feasibility and impact assessment of RFID application in blood centre operations. MATERIALS AND METHODS Our comprehensive assessment approach incorporates process-orientated and technological perspectives as well as impact analysis. Assessment of RFID-enabled process redesign is based on generic core processes derived from the three participating blood centres. The technological assessment includes RFID tag readability and performance evaluation, testing of temperature and biological effects of RF energy on blood products, and RFID system architecture design and standards. The scope of this article is limited to blood centre processes (from donation to manufacturing/distribution) for selected mainstream blood products (red blood cells and platelets). RESULTS Radio frequency identification can help overcome a number of common challenges and process inefficiencies associated with identification and tracking of blood products. High frequency-based RFID technology performs adequately and safely for red blood cell and platelet products. Productivity and quality improvements in RFID-enabled blood centre processes can recoup investment cost in a 4-year payback period. CONCLUSION Radio frequency identification application has significant process-orientated and technological implications. It is feasible and economically justifiable to incorporate RFID into blood centre processes.

Abstract
Can the media reduce intergroup prejudice and conflict? Despite the high stakes of this question, understanding of the mass media's role in shaping prejudiced beliefs, norms, and behavior is limited. A yearlong field experiment in Rwanda tested the impact of a radio soap opera featuring messages about reducing intergroup prejudice, violence, and trauma in 2 fictional Rwandan communities. Compared with a control group who listened to a health radio soap opera, listeners' perceptions of social norms and their behaviors changed with respect to intermarriage, open dissent, trust, empathy, cooperation, and trauma healing. However, the radio program did little to change listeners' personal beliefs. Group discussion and emotion were implicated in the process of media influence. Taken together, the results point to an integrated model of behavioral prejudice and conflict reduction that prioritizes the communication of social norms over changes in personal beliefs.

Abstract
Assessment of occupational exposure to radiofrequency (RF) fields in telecommunication transmitter masts is a challenging task. For conventional field strength measurements using manually operated instruments, it is difficult to document the locations of measurements while climbing up a mast. Logging RF dosemeters worn by the workers, on the other hand, do not give any information about the location of the exposure. In this study, a practical method was developed and applied to assess mast workers' exposure to RF fields and the corresponding location. This method uses a logging dosemeter for personal RF exposure evaluation and two logging barometers to determine the corresponding height of the worker's position on the mast. The procedure is not intended to be used for compliance assessments, but to indicate locations where stricter assessments are needed. The applicability of the method is demonstrated by making measurements in a TV and radio transmitting mast.

Abstract
Makgabaneng is an entertainment-education radio serial drama written and produced in Botswana to promote prevention of HIV. This effort is part of the national response to HIV/AIDS. Broadcast of the serial drama began in August 2001, and two new 15-minute episodes air each week. We examined associations between exposure to Makgabaneng and outcomes related to HIV testing, including stigmatizing attitudes, intention to be tested, talking with a partner about testing, and testing for HIV, among 555 sexually active respondents. The four measures of exposure to Makgabaneng were frequency of listening, duration of listening, talking about the program, and attentiveness to and identification with relevant characters. Data were collected approximately 18 months after the drama began airing. We found positive associations between exposure to the program and intermediate outcomes, including lower level of stigmatizing attitudes, stronger intention to have HIV testing, and talking to a partner about testing. Although associations were identified with all four measures of exposure, increased duration of listening was associated with more positive outcomes than the other measures. This finding suggests that longer term exposure to entertainment-education programming may be important for behavior change.
