Abstract
In the United States, heterosexual transmission of HIV infection is dramatically higher among Blacks than among Whites. Overlapping (concurrent) sexual partnerships promote HIV transmission. The authors describe their process for developing a radio campaign (Escape the Web) to raise awareness among 18-34-year-old Black adults of the effect of concurrency on HIV transmission in the rural South. Radio is a powerful channel for the delivery of narrative-style health messages. Through six focus groups (n = 51) and 42 intercept interviews, the authors explored attitudes toward concurrency and solicited feedback on sample messages. Men were advised to (a) end concurrent partnerships and not to begin new ones; (b) use condoms consistently with all partners; and (c) tell others about the risks of concurrency and benefits of ending concurrent partnerships. The narrative portrayed risky behaviors that trigger initiation of casual partnerships. Women were advised to (a) end partnerships in which they are not their partner's only partner; (b) use condoms consistently with all partners; and (c) tell others about the risks of concurrency and benefits of ending concurrent partnerships. Messages for all advised better modeling for children.

Abstract
INTRODUCTION Electronic devices in the bedroom are broadly linked with poor sleep in adolescents. This study investigated whether there is a dose-response relationship between use of electronic devices (computers, cellphones, televisions and radios) in bed prior to sleep and adolescent sleep patterns. METHODS Adolescents aged 11-17 yrs (n = 1,184; 67.6% female) completed an Australia-wide internet survey that examined sleep patterns, sleepiness, sleep disorders, the presence of electronic devices in the bedroom and frequency of use in bed at night. RESULTS Over 70% of adolescents reported 2 or more electronic devices in their bedroom at night. Use of devices in bed a few nights per week or more was 46.8% cellphone, 38.5% computer, 23.2% TV, and 15.8% radio. Device use had dose-dependent associations with later sleep onset on weekdays (highest-dose computer adjOR = 3.75: 99% CI = 2.17-6.46; cellphone 2.29: 1.22-4.30) and weekends (computer 3.68: 2.14-6.32; cellphone 3.24: 1.70-6.19; TV 2.32: 1.30-4.14), and later waking on weekdays (computer 2.08: 1.25-3.44; TV 2.31: 1.33-4.02) and weekends (computer 1.99: 1.21-3.26; cellphone 2.33: 1.33-4.08; TV 2.04: 1.18-3.55). Only 'almost every night' computer use (: 2.43: 1.45-4.08) was associated with short weekday sleep duration, and only 'almost every night' cellphone use (2.23: 1.26-3.94) was associated with wake lag (waking later on weekends). CONCLUSIONS Use of computers, cell-phones and televisions at higher doses was associated with delayed sleep/wake schedules and wake lag, potentially impairing health and educational outcomes.

Abstract
The robustness of the human auditory system to noise is partly due to the peak preserving capability of the periphery and the cortical filtering of spectro-temporal modulations. In this letter, a robust speech feature extraction scheme is developed that emulates this processing by deriving a spectrographic representation that emphasizes the high energy regions. This is followed by a modulation filtering step to preserve only the important spectro-temporal modulations. The features derived from this representation provide significant improvements for speech recognition in noise and language identification in radio channel speech. Further, the experimental analysis shows congruence with human psychophysical studies.

Abstract
About 4 million children die every year as a result of dehydration caused by acute diarrhoea. Oral rehydration therapy (ORT) is designed to prevent dehydration. In the past 10 years, several campaigns have been conducted throughout the world, mostly sponsored by the World Health Organization, to disseminate ORT, particularly in developing countries. This paper presents a review of 14 ORT campaigns categorising their components according to whether the researchers used antecedents, behaviours, and/or consequences. Only three campaigns manipulated all three components. Antecedent events were manipulated in all of the studies. A skills training component appears to influence the effectiveness of the campaign, since several new behaviours and complex discriminations need to be learned for people to use ORT correctly. The benefits of functionally analysing the components of current ORT campaigns are highlighted.

Abstract
This article examines taste clusters of musical preferences and substance use among adolescents and young adults. Three analytic levels are considered: fixed effects analyses of aggregate listening patterns and substance use in US radio markets, logistic regressions of individual genre preferences and drug use from a nationally representative survey of US youth, and arrest and seizure data from a large American concert venue. A consistent picture emerges from all three levels: rock music is positively associated with substance use, with some substance-specific variability across rock sub-genres. Hip hop music is also associated with higher use, while pop and religious music are associated with lower use. These results are robust to fixed effects models that account for changes over time in radio markets, a comprehensive battery of controls in the individual-level survey, and concert data establishing the co-occurrence of substance use and music listening in the same place and time. The results affirm a rich tradition of qualitative and experimental studies, demonstrating how symbolic boundaries are simultaneously drawn around music and drugs.

Abstract
Narrowbanding has caused numerous communication issues. The solution is to use a mutual aid frequency like 123.025. That frequency is 155.3400, and every helicopter emergency medical service operator and emergency medical service agency should name this frequency as "EMS [Emergency Medical Services] Mutual Aid" and preset this frequency for all helicopter emergency medical service scene operations.

Abstract
INTRODUCTION Nigeria, the only African country endemic for wild poliovirus, adopted Immunization Plus Days (IPD) to eradicate polio. Refusal of oral polio vaccine (OPV) by heads of households is a significant challenge. In Sokoto state, we determined characteristics of heads of households refusing OPV during IPD in 2011. METHODS To evaluate reasons for refusals, we conducted a case control study among heads ofhouseholds accepting or refusing OPV vaccine. Noncompliant households were defined as households refusing OPV vaccination in last three rounds of IPDs while compliant households were those accepting vaccination. Interviewers administered a questionnaire to the heads of households to obtain information on socio-demographics, media habits, and knowledge of IPD. RESULTS Of the 121 (60 cases and 61 controls) interviews, 88 (73%) were from Sokoto north. Noncompliant heads of households were more likely to lack tertiary education (OR = 3.7, 95% CI, 1.6 - 9.2), believe that OPV is not safe (OR = 22, 95% CI, 7.1 - 76), lack access to functional radio (OR = 4.4, 95% CI, 1.4 - 15) and television (OR = 9.4, 95% CI, (1.9 - 63) andget information about IPD from town announcers (OR = 3.9, 95% CI, 1.3 - 12). CONCLUSION We conclude that noncompliant heads of households compared to compliant heads of households had low level of education, lacked knowledge of immunization, and had negative attitude towards OPV. They get information about OPV from town announcers and lacked access to functional radio and television. We recommended training of town announcers in polio communication and use of key communication messages preceding every round of IPD.

Abstract
Cognitive radio (CR) enables unlicensed users (or secondary users, SUs) to sense for and exploit underutilized licensed spectrum owned by the licensed users (or primary users, PUs). Reinforcement learning (RL) is an artificial intelligence approach that enables a node to observe, learn, and make appropriate decisions on action selection in order to maximize network performance. Routing enables a source node to search for a least-cost route to its destination node. While there have been increasing efforts to enhance the traditional RL approach for routing in wireless networks, this research area remains largely unexplored in the domain of routing in CR networks. This paper applies RL in routing and investigates the effects of various features of RL (i.e., reward function, exploitation, and exploration, as well as learning rate) through simulation. New approaches and recommendations are proposed to enhance the features in order to improve the network performance brought about by RL to routing. Simulation results show that the RL parameters of the reward function, exploitation, and exploration, as well as learning rate, must be well regulated, and the new approaches proposed in this paper improves SUs' network performance without significantly jeopardizing PUs' network performance, specifically SUs' interference to PUs.

Abstract
The decision made by migrating birds to stop refueling and to depart from stopover depends on cues from innate rhythms, intrinsic factors such as fuel reserves, and extrinsic factors such as weather conditions. The physiological mechanism behind this decision, however, is largely unexplored. The transition from refueling to flight involves an increase in both locomotion and energetic demands. Because, at baseline levels, corticosterone stimulates locomotion and is involved in the mobilization of energy, this hormone could encourage departure of migrants. We collected field data on baseline corticosterone, migratory restlessness, and actual departure in northern wheatears at stopover. Additionally, in refueling long-term captive conspecifics, we measured migratory restlessness while simultaneously collecting droppings to determine glucocorticoid metabolite (GCM) levels. We found that migratory restlessness at stopover was positively correlated with corticosterone level. Similarly, in refueling long-term captive birds, migratory restlessness was positively correlated with concurrently measured GCM levels in droppings. To our best knowledge, our study is the first to simultaneously measure a hormonal signal and migratory restlessness. In conclusion, our results are consistent with the hypothesis that, by increasing locomotor activity, baseline corticosterone is involved in the regulation of departure of migrants at stopover. Future studies could reveal how corticosterone is up-regulated in migrants that are ready to depart.

Abstract
This research examines the distributional characteristics of Czech ř in terms of the number of contacts (periods). The traditional claim that this consonant is produced with two or more contacts is challenged by the empirical evidence of ř realized in connected speech (newsreading style). The results of the study show that the most common variant of the (ř) variable is a one-contact alveolar sound, with the multiple-contact realization of ř being extremely rare. The role of eight linguistic variables is assessed in order to find out which factors are most likely to influence the number of contacts of Czech ř. Some questions are discussed concerning its current definition as a trill.

Abstract
OBJECTIVE To explore similarities and differences in the use and perception of communication channels to access weight-related health promotion among women in three ethnic minority groups. The ultimate aim was to determine whether similar channels might reach ethnic minority women in general or whether segmentation to ethnic groups would be required. DESIGN Eight ethnically homogeneous focus groups were conducted among 48 women of Ghanaian, Antillean/Aruban, or Afro-Surinamese background living in Amsterdam. Our questions concerned which communication channels they usually used to access weight-related health advice or information about programs and whose information they most valued. The content analysis of data was performed. RESULTS The participants mentioned four channels - regular and traditional health care, general or ethnically specific media, multiethnic and ethnic gatherings, and interpersonal communication with peers in the Netherlands and with people in the home country. Ghanaian women emphasized ethnically specific channels (e.g., traditional health care, Ghanaian churches). They were comfortable with these channels and trusted them. They mentioned fewer general channels - mainly limited to health care - and if discussed, negative perceptions were expressed. Antillean women mentioned the use of ethnically specific channels (e.g., communication with Antilleans in the home country) on balance with general audience-oriented channels (e.g., regular health care). Perceptions were mixed. Surinamese participants discussed, in a positive manner, the use of general audience-oriented channels, while they said they did not use traditional health care or advice from Surinam. Local language proficiency, time resided in the Netherlands, and approaches and messages received seemed to explain channel use and perception. CONCLUSIONS The predominant differences in channel use and perception among the ethnic groups indicate a need for channel segmentation to reach a multiethnic target group with weight-related health promotion. The study results reveal possible segmentation criteria besides ethnicity, such as local language proficiency and time since migration, worthy of further investigation.

Abstract
A nanoradio based on the mechanical resonance of a nanomaterial has promising applications in terms of size reduction of an antenna and integrity of all components of a radio except a speaker. In this letter, a nanopillar array radio utilizing the mechanical resonance of a vertically aligned nanopillar array is realized by a reliable top-down method. By exploiting the field emission phenomenon, it was found that the nanopillar array functions as a radio with a demodulator without any electrical circuitry. The array of vertically aligned nanopillars increases the demodulated current and signal to noise ratio, and this fabrication method makes manipulation and positioning of nanostructures possible intrinsically for industrial applications.

Abstract
Despite early widespread recognition of the necessity of continuing medical education (CME) for practicing physicians and surgeons, medical schools and national medical organizations were slow to mobilize to address the need. One pioneering program, developed by the Albany Medical College in New York, not only provided CME, but did so in a live distance education format that allowed for interaction between the participants and the faculty presenters. The Albany Program commenced in 1955 using what was then state-of-the-art technology; it exemplified principles and practices that can be seen as the precursors for the distance education approaches used to reach physicians today. This short article describes the contributions of the Albany Two-Way Radio Conferences and places them in the context of developments in national organizations and policies in the 20th century.

Abstract
Energy-efficient communication is one of the main concerns of wireless sensor networks nowadays. A commonly employed approach for achieving energy efficiency has been the use of duty-cycled operation of the radio, where the node's transceiver is turned off and on regularly, listening to the radio channel for possible incoming communication during its on-state. Nonetheless, such a paradigm performs poorly for scenarios of low or bursty traffic because of unnecessary activations of the radio transceiver. As an alternative technology, Wake-up Radio (WuR) systems present a promising energy-efficient network operation, where target devices are only activated in an on-demand fashion by means of a special radio signal and a WuR receiver. In this paper, we analyze a novel wake-up radio approach that integrates both data communication and wake-up functionalities into one platform, providing a reconfigurable radio operation. Through physical experiments, we characterize the delay, current consumption and overall operational range performance of this approach under different transmit power levels. We also present an actual single-hop WuR application scenario, as well as demonstrate the first true multi-hop capabilities of a WuR platform and simulate its performance in a multi-hop scenario. Finally, by thorough qualitative comparisons to the most relevant WuR proposals in the literature, we state that the proposed WuR system stands out as a strong candidate for any application requiring energy-efficient wireless sensor node communications.

Abstract
'DU bist Radio' (DBR) is an award winning [DBR has been awarded with the "Catholic Media Award of the German Bishops Conference, Prädikat WERTvoll" (2011), the Suisse "Media Prize Aargau/Solothurn" (2010), the German "Alternative Media Award" (2009) and was nominated for the "Prix Europa" (2009)] monthly radio format that goes on air on three Swiss radio stations. The purpose of this program which was first broadcast in 2009 is the development of a new media format which--without applying any journalistic (or other) filter and influence--conveys authenticity of expression amongst society's most vulnerable fellow citizens such as patients, clients and the socially deprived. So-called marginal groups are encouraged to speak for themselves, as a possible paradigm case for encouraging the inclusion of patients' and relatives' "unfiltered" voices in general and in clinical ethics as well. Before handing over the microphone to the groups in focus, a team of journalists, educated in medical ethics, over a period of 4 days, teaches them on-site radio skills and craft. Once this task is completed and the actual production of the broadcast begins, the media crew does not exert any influence whatsoever on the content of the 1-h program. Thus, the final product is solely created and accounted for by the media-inexperienced participants, leading to unforeseen and often surprising results. It is discussed that the DBR approach of fostering authenticity of expression can serve as an enhancement to today's respect and autonomy oriented field of medical ethics.

Abstract
OBJECTIVE To examine whether a radio-education intervention (REI) is associated with improved maternal knowledge of pregnancy danger signs (PDS) in Nicaragua. METHODS This cross-sectional pilot study used pretests and posttests to evaluate whether an REI was associated with improved knowledge of PDS among 77 pregnant and postpartum women in Nicaragua. RESULTS The total number of PDS identified by study participants increased from 130 before the intervention to 200 after the intervention, an increase of 53.8% (Wilcoxon signed-rank test (z) = -4.18; P < 0.00001). The three PDS for which participant knowledge increased significantly after the intervention were 1) swelling of the face and hands, 2) convulsions, and 3) vaginal bleeding. Participants who 1) reported having a sister who had experienced a pregnancy complication, 2) lived in an urban setting, and 3) had more than a sixth-grade education were significantly more likely to score higher on posttests related to knowledge of PDS than those without those attributes (90.9% versus 56.9% [Χ² (degrees of freedom) = 4.60 (1); P = 0.043; n = 76]; 75% versus 45.9% [Χ² = 6.8 (1); P = 0.009; n = 77]; and 62.5% (12+ years education) versus 79.3% (6-12 years) versus 50.0% (0-6 years education) versus 25.0% (no education) [Χ² = 8.11 (1); P = 0.044; n = 77] respectively). CONCLUSIONS Exposure to the REI was associated with a significant increase in the ability to identify PDS. Further studies should establish whether this increase in knowledge of PDS is associated with increases in use of maternity care services and decreases in delays in seeking care.

Abstract
The intent of this article is to assess the current state of Emergency Warning capabilities in the United States and make recommendations on what needs to be done to cost effectively establish a National Emergency Warning System to best serve the people of the United States, including those with disabilities. As part of this assessment, terminology will be defined, existing systems will be examined, critical needs and functions will be explained, and recommendations made for a system to deliver emergency messages to those people immediately at risk from natural and human-caused disasters in a timely and effective manner, regardless of location or situational circumstance. The assessment will include the needs and available technologies for delivering emergency warnings to people with disabilities, which are generally little understood, poorly addressed, and often ignored.

Abstract
Successful strategies for recruitment and retention (R & R) in pediatric trials are needed. The purpose of our study was to analyze the effectiveness of R&R in a trial for children with hepatitis C. Recruitment strategies were (1) Initial (months 0-12) and (2) extra effort (months 13-18). Initial strategies enrolled 70/114 (61%) of patients. Extra effort strategies included: (1) radio broadcasts, (2) contact with adult hepatologists, (3) dissemination of study material and (4) modification of the exclusion criteria. The overall retention rate was 84% at 2 years. Lessons learned will be valuable in designing future pediatric trials.
