Improved decision for a resource-efficient fusion scheme in cooperative spectrum sensing

Paper presented at at 2015 International Workshop on Telecommunications (IWT), 14th to 17th of June, Santa Rita do Sapucai, Brazil. Abstract Recently, a novel decision fusion scheme for cooperative spectrum sensing was proposed, aiming at saving resources in the reporting channel transmissions. Secondary users are allowed to report their local decisions through the symbols of binary modulations, at the same time and with the same carrier frequencies. As a consequence, the transmitted symbols add incoherently at the fusion center, forming a larger set of symbols in which a subset is associated to the presence of the primary signal, and another subset is associated to the absence of such a signal. A Bayesian decision criterion with uniform prior was applied for discriminating these subsets. In this paper we propose a modified decision rule in which the target probabilities of detection and false alarm are taken into account to produce a large performance improvement over the original decision criterion. This improvement comes with practically no cost in complexity and does not demand the knowledge of any additional information when compared to the original rule

Women's views of continuity of information provided during and after pregnancy: A qualitative interview study

Straightforward transfer of care from pregnancy to the postpartum period is associated with health benefits and is desired by women worldwide. Underpinning this transfer of care is the sharing of information between healthcare professionals and the provision of consistent information to women. In this qualitative study, two aspects of continuity of information were examined; first the information passed on from midwife to health visitor regarding a woman and her baby before the health visitor meets the woman postnatally and second, the consistency of information received by women from these two healthcare professionals (the main healthcare providers during and after pregnancy in England). To be eligible for the study, women had to have had a baby in England within 12 months prior to the interview. Participants also needed to be able to read and speak English and be over 18 years old. Recruitment of participants was via word of mouth and social media. Twenty-nine mothers were interviewed of whom 19 were first time mothers. The interviews took place in the summer and autumn of 2016 and were transcribed verbatim and analysed using Framework Analysis. Two overarching themes were identified: not feeling listened to and information inconsistencies. Women reported little experience of midwives and health visitors sharing information about their care, forcing women to repeat information. This made women feel not listened to and participants recommended that healthcare professionals share information; prioritising information about labour, mental health, and chronic conditions. Women had mixed experiences regarding receiving information from midwives and health visitors, with examples of both consistent and inconsistent information received. To avoid inconsistent information, joint appointments were recommended. Findings from this study clearly suggest that better communication pathways need to be developed and effectively implemented for midwives and health visitors to improve the care that they provide to women

California Constitutional Law: Privacy

California voters passed Proposition 11 (the Privacy Initiative) in 1972, amending the state constitution to include a fundamental right to privacy. The ballot arguments for Proposition 11 expressed the voters’ intent to set a high bar for invaders to justify privacy invasions: requiring a compelling public need. For the first twenty years of the new constitutional privacy right’s existence, courts required invaders of individual privacy to meet the compelling public need standard to justify such invasions. Yet the courts reversed course in 1994, abandoned the compelling public need standard, and have since applied a standard that perverts the electorate’s intent: now, the individual must establish a compelling privacy interest against invasions. This approach to California’s constitutional privacy right has sabotaged the Privacy Initiative. This Article presents six substantive arguments for abandoning the current approach and returning this area of the law to its original intent. This Article supports its substantive analysis with an empirical case study showing that the current approach maimed California’s constitutional privacy right. It’s time to reset this area of the law. California courts should abandon the current analytical approach to the state’s constitutional privacy right and restore the original interpretation of the Privacy Initiative: the compelling public need test that the voters intended

Women’s views on contact with a health visitor during pregnancy: an interview study

Aim: To explore recent mothers’ views of the health visiting antenatal contact in England. Background: English health visitors are mandated to be in contact with all women in the third trimester of pregnancy. The aim of this antenatal contact is to assess the needs of the family before the birth and support preparation for parenthood. Recent data show that this contact is provided fragmentarily and not always face-to-face. More information on how women view this contact could inform service provision. Methods: Twenty-nine mothers with a baby less than 1 year old were recruited via social media and word of mouth. Having had antenatal contact with a health visitor was not a requirement to participate in the study. Women took part in face-to-face or phone interviews and all recordings were transcribed verbatim. Data were analysed using systematic thematic analysis. Findings: Eleven women had contact with a health visitor during pregnancy: nine through a home visit, one via a letter and one via a phone call. The remaining 18 women were asked about what they would have wanted from an antenatal contact. Three themes were identified: relationship building, information provision, and mode and time of contact. Some participants who had experienced a home visit reported building rapport with their health visitor before the postnatal period, but not everyone had this experience. Women reported requesting and receiving information about the health visiting service and the role of the health visitor. Finally, women suggested different modes of contact, suggesting a letter or that the information about health visiting could be provided by a midwife. A few women preferred a home visit. These study findings show women were unclear regarding the aim of the health visitor antenatal contact. As such, the contact is unlikely to reach its full potential in supporting parents-to-be

Instalación de arosmagnéticos en el aula Magna de la UNNE y el Auditorio de la Facultad de Abogacía

La experiencia adquirida por el GRIER en el diseño de sistemas de aros magnéticos, agregada a la posibilidad de canalizar estos desarrollos como transferencia tecnológica desde la universidad al medio, y sabiendo que no existen dispositivos comerciales de estas características en el mercado nacional, motivaron en conjunto con las autoridades de la Universidad Nacional del Nordeste, y gestionada a través de la cátedra libre “Diseño universal e Inclusión de la unne”, el desarrollo e instalación de dos sistemas de aros magnéticos en auditorios de grandes dimensiones como ser el Aula Magna de la unne sita en la Facultad de Humanidades (Rcia-Chaco) y el Auditorio ubicado en la Facultad de Abogacía en la ciudad de Corrientes. La idea fue ofrecer a personas con hipoacusia que utilizan audífonos comerciales, de un ambiente con la tecnología de los aros magnéticos que permitiera eliminar el ruido el entorno para optimizar la señal de audio o la voz del locutor.
