Human exposure to electromagnetic fields from WLANs and WBANs in the 2.4 GHz band

226 p.En los últimos años, el masivo crecimiento de las comunicaciones inalámbricas ha incrementado la preocupación acerca de la exposición humana a los campos electromagnéticos debido a los posibles efectos sobre la salud. Esta tesis surge de la necesidad de proporcionar información acerca de este tipo de exposición desde un punto de vista técnico. Por una parte, se han estudiado los niveles de exposición causados por señales WiFi, para lo cual ha sido necesario establecer un procedimiento de medida adecuado para tomar muestras de estas emisiones. Además, se han llevado a cabo campañas de medida para evaluar la exposición a señales WiFi y su variabilidad en el interior de un entorno público. Por otra parte, se ha analizado la potencia absorbida por el cuerpo humano a causa de los novedosos dispositivos wearables. Se han implementado dos antenas de este tipo, apropiadas para dispositivos wearables, se ha analizado detalladamente la exposición debida a estos aparatos y finalmente se han comparado los niveles de exposición producidos por estas antenas y por las señales WiFi

The feasibility and potential effectiveness of a conventional and exergame intervention to alter balance-related outcomes including fall risk: a mixed methods study

Introduction: Fall risk, occurrence and injury is increasing as the world ages, and Africa and other emerging regions will not be spared. Similarly, the rise of noncommunicable diseases, compressed morbidity and lack of physical activity present major challenges. This novel feasibility study explored the use of an exergaming technology compared with a conventional, evidence-based exercise programme (Otago Exercise Programme) to reduce fall risk by improving balance, and to inform a large-scale randomised control trial. Methodology: Mixed methods study in independent older adults with established fall risk. The quantitative component employed feasibility RCT methodology. Cluster randomisation assigned interventions to sites. Single blinding was used. Both interventions were offered for six months. A variety of balance-related endpoints (e.g., Timed Up and Go, Dynamic Gait Index, Mini-BESTest) were used to find the most applicable. Patient-centred variables included questionnaires regarding depression, physical activity levels, quality of life and estimates of self-efficacy for exercise. Qualitative focus groups explored participants' experiences of falls and the exergaming intervention using a phenomenology lens. Results: Site and participant recruitment was simple and readily achievable, with low numbers need to screen required. Eligibility criteria were confirmed and more added. Adherence and attrition were major challenges. Cluster randomisation appeared to exacerbate between-group differences at baseline. The exergaming intervention produced preliminary evidence in its favour, with results approaching Minimal Clinically Important Difference compared with the evidence-based intervention. The experience of the exergaming intervention was regarded as positive by focus group participants. Barriers and facilitators are reported. Discussion: Methodological issues in the literature have prevented firm consensus on the use of exergaming in falls prevention, although studies are abundant. The current study used rigorous methodology in the novel context of a developing region, which offers numerous challenges for older adults. Implications for a large-scale, fully funded RCT are discussed. Lessons learned can be used to scale up service delivery for an under-served population; and promote the aim of well-being for all at all ages

Chaucer's Arthuriana

I trace Chaucer's increasingly complex use of the Arthurian legend. In his early dream visions, Chaucer mirrors his Italian and French sources; however, his Arthurian allusions diverges from his predecessors to reflect the negative attitude found in fourteenth-century England towards the Arthurian myth. In Troilus and Criseyde, Chaucer is indebted to the French tradition; he models Troilus on Lancelot. In The Canterbury Tales, Chaucer explores how the Arthurian legend permeates contemporary English society, critiquing both the clergy, who cite the legend's lack of morality, and the aristocracy, who use the legend to establish a superficial superiority. Through his invocation of the popular figure of Gawain in The Tale of Sir Thopas and The Wife of Bath's Tale, Chaucer criticizes his fellow romance writers in the former tale and offers an Arthurian tale from the mouth of one of the female pilgrims in the latter. The Wife of Bath rejects the traditional glorification of Gawain in order to recast him as a nameless rapist, stripped of his famous name as punishment for his transgression of female sovereignty

Balance disorder after traumatic brain injury : A multifactorial observational study.

This research was undertaken to improve the assessment and treatment of balance disorder after Traumatic Brain Injury (TBI). It had three aims: to identify factors that have shaped healthcare practice concerning balance disorder and describe barriers to improved practice•; to develop understanding of the nature of TBI balance disorder; to establish proposals for an improved healthcare response for those with balance disorder following TBI. TBI is a significant cause of disability in the young adult population and problems with balance are consistently reported. A mixed methods approach was employed to address the aims within a common framework. This comprised a series of subject reviews, an observational study and a systematic analysis of emergent findings. Topics for the subject reviews were chosen for their relevance to TBI physiotherapy practice. The observational study involved 27 participants in the recovery and rehabilitation phase after TBI and was structured using a new comprehensive assessment protocol developed from first principles. Findings were explored using frequency analysis and thematic analysis generated from the development of individual participant narratives. Emergent topics were then considered with reference to the literature, existing theories and concepts of postural control. Different conceptualisations of balance were identified, influenced by discipline tradition, their evidence base, the evolution of ideas, and past and current purpose. Practice development was constrained by the lack of a comprehensive conceptualisation of human balance, inconsistent and fragmented service response and limited knowledge concerning the nature and prevalence of impairments affecting balance function after TBI. Balance disorder was found to be highly prevalent and multifactorial in nature. New sensorimotor characteristics of TBI balance disorder were identified, including observations of importance to the contentious debate concerning symptomatic minor TBI. Issues of key importance in the structure and process of assessment were also identified. Balance disorder is prevalent in the rehabilitation and recovery phase following TBI and is multifactorial in nature. Assessment and treatment of suspected balance disorder could be enhanced by the adoption of a single comprehensive conceptualisation of human balance, a systematic approach to assessment and formulation of causal hypotheses and a service process focused on the functional requirements of individuals. Research for the enhanced development of assessment and intervention strategies should also be pursued in the same context

James Michael Curley Scrapbooks Volume A21

The James Michael Curley Scrapbook Collection consists of digitized microfilmed copies of notebooks kept by Curley from 1914-1937. These notebooks contain news clippings that were drawn primarily from Boston newspapers. Curley was born in Roxbury, MA in 1874. He served four terms as Mayor of Boston: 1914–1918, 1922–1926, 1930–1934 and 1946–1950. He also served as Governor of Massachusetts from 1935-1937. In addition to Curley’s political career, the scrapbooks also include clippings about his first wife Mrs. Mary Herlihy Curley (1884-1930) and their daughter Mary D. Curley (1909-1950). A selection of the notebooks were microfilmed in 1962. The microfilm can be found in the holdings of Dinand Library, Holy Cross’s main library. This volume includes clippings from 1917.https://crossworks.holycross.edu/curley_scrapbooks/1010/thumbnail.jp
