Feasibility of Dual-Task Gait Training for Community-Dwelling Adults after Stroke: A Case Series
Prudence Plummer,Raymond M. Villalobos,Moira S. Vayda,Myriam Moser,Erin Johnson
Stroke Research and Treatment , 2014, DOI: 10.1155/2014/538602
Abstract: This case series explored the feasibility and efficacy of cognitive-motor dual-task gait training in community-dwelling adults within 12 months of stroke. A secondary aim was to assess transfer of training to different dual-task combinations. Seven male participants within 12 months of stroke participated in 12 sessions of dual-task gait training. We examined single and dual-task performance in four different dual-task combinations at baseline, after 6 and 12 sessions, and if possible, at 1-month followup. Feasibility was assessed by asking participants to rate mental and physical fatigue, perceived difficulty, anxiety, and fear of falling at the end of each session. Five of the seven participants demonstrated reduced dual-task cost in gait speed in at least one of the dual-task combinations after the intervention. Analysis of the patterns of interference in the gait and cognitive tasks suggested that the way in which the participants allocated their attention between the simultaneous tasks differed across tasks and, in many participants, changed over time. Dual-task gait training is safe and feasible within the first 12 months after stroke, and may improve dual-task walking speed. Individuals with a combination of physical and cognitive impairments may not be appropriate for dual-task gait training. 1. Introduction Cognitive-motor dual-task interference, defined as the decrement in performance that occurs when cognitive and motor tasks are performed simultaneously, has been well established in people after stroke [1–9]. This growing body of research has demonstrated significant dual-task decrements in gait speed [1, 5, 8], stride length [5, 8], cadence [6, 8], stride duration [2, 4, 8], and double limb support duration [1, 7]. In other words, compared to single-task walking, when individuals with stroke perform a cognitive task while walking they are less stable and take shorter, slower steps, resulting in a dramatic cost on gait speed. Gait-related dual-task deficits persist in community-dwelling stroke survivors many months after discharge from rehabilitation [3, 5, 8]. Since walking in the community is often performed concurrently with cognitive tasks, such as remembering directions or engaging in social interactions, a reduced capacity for dual-task walking may restrict the degree to which a person is able to physically function and participate in their life roles. Conventional rehabilitation does not appear to adequately address gait-related dual-task interference. For example, in a longitudinal study of cognitive-motor interference, Cockburn and
Anthropologie des enjeux de la violence chez lagunaires de C te d’Ivoire
M Raymond
African Sociological Review / Revue Africaine de Sociologie , 2009,
Abstract: Le projet d’une C te d’Ivoire nouvelle suscite particulièrement dans les communautés lagunaires une dynamique de transformation des ordres sociaux (institutions, idéologie des classes d’age, matrilinéarité) face aux nouveaux enjeux qui mobilisent les populations (démocratie, développement, bien-être des populations, respect des institutions, création de nouvelles richesses, etc.). L’analyse socio-anthropologique de la micro-violence dans ces communautés à travers ces ordres sociaux et leur transformation, la justification des indices d’expression de la violence et les enjeux de celle-ci dans la transformation sociale, révèle que la violence en s’inscrivant dans ce processus comme un désordre apparent (Gbudzu-gbudzu), mieux comme un moyen de passage de l’ordre ancien à l’ordre nouveau, est au surplus le thermostat dans la bonne marche de la transformation sociale pour un mieux être. Mots-clés: Micro-violence, matrilinéarité, classes d’age, développement, conflit, désordre, transformation,
Contribución de Enfermería en la prevención y detección temprana de la Sepsis
Villalobos M,Idelma;
Kasmera , 2005,
Abstract: the purpose of the present work was to do a review on the "surviving sepsis campaign" and to contribute to its diffusion in our environment, taking into consideration the necessary operability for its adaptation. from a revision of the medical and nursing journals, stands out the fact that, advances in the management of severe sepsis, the understanding of patho-physiology and new treatment strategies, have not reduced the sepsis mortality. in that sense, certain initiatives have been developed. one of which is the sepsis survival campaign wich has divulged guidelines for severe sepsis and septic shock management. nevertheless, it should be acknowledged that the main measure to undertake is that of prevention, for which nursing is best indicated as its professionals are in the best position to identify early signs due to the close relationship and continuous care of the patient.
Big Data Stream Analytics for Near Real-Time Sentiment Analysis  [PDF]
Otto K. M. Cheng, Raymond Lau
Journal of Computer and Communications (JCC) , 2015, DOI: 10.4236/jcc.2015.35024
Abstract:

In the era of big data, huge volumes of data are generated from online social networks, sensor networks, mobile devices, and organizations’ enterprise systems. This phenomenon provides organizations with unprecedented opportunities to tap into big data to mine valuable business intelligence. However, traditional business analytics methods may not be able to cope with the flood of big data. The main contribution of this paper is the illustration of the development of a novel big data stream analytics framework named BDSASA that leverages a probabilistic language model to analyze the consumer sentiments embedded in hundreds of millions of online consumer reviews. In particular, an inference model is embedded into the classical language modeling framework to enhance the prediction of consumer sentiments. The practical implication of our research work is that organizations can apply our big data stream analytics framework to analyze consumers’ product preferences, and hence develop more effective marketing and production strategies.

Fixed points and self-reference
Raymond M. Smullyan
International Journal of Mathematics and Mathematical Sciences , 1984, DOI: 10.1155/s0161171284000296
Abstract: It is shown how G del's famous diagonal argument and a generalization of the recursion theorem are derivable from a common construation. The abstract fixed point theorem of this article is independent of both metamathematics and recursion theory and is perfectly comprehensible to the non-specialist.
Succession and Renewal in Urban Neighborhoods: The Case of Coney Island
Raymond M. Weinstein
Sociation Today , 2007,
Abstract: Sociologists for some time have used the concepts of succession and renewal to describe two different, but sometimes complementary, processes of neighborhood change in urban areas. Coney Island has long been famous as an amusement area popular in New York City, but today the area has fallen on hard times. Developers want to tear down the amusement area of Coney Island and replace it with condos for the well-to-do. This process is discussed in light of classic sociological theories of urban change and renewal.
El enlucido exterior de yeso en las rehabilitaciones de las fachadas de París
Raymond Pigache, M.
Informes de la Construccion , 1986,
Abstract: The use, the manufacture, the putting into excution of gypsum plaster on old Paris fa ades -a marely manual technique- are specified since long ago. A number of gypsum plaster carried out under Louis the 14th reign, have still a good behaviour in spite of, as it is well known, gypsum in the outside is very sensible to dissolution. This study allows to clarify four fundamental parameters, and its conclusions make it possible to carry out rehabilitations both in prestigeous and in humble buildings: - The use of a mortar which components will be similar to those old materials; - A merely handwork. - An established proportion with a view to protect the gypsum plasters, cornices, moldings, etc. from drainage waters. - Bearing walls with higher mechanical characteristics than those of platers. La utilización, fabricación y puesto en obra de morteros de yeso, sobre las fachadas antiguas en el viejo París -técnica puramente manual-, están precisadas desde hace mucho tiempo. Numerosos enlucidos de mortero de yeso, realizados bajo el reinado de Luis XIV, presentan todavía un excelente comportamiento a pesar de que, como es sabido, el yeso en exteriores es muy sensible a disolverse. Este estudio ha permitido aclarar cuatro parámetros fundamentales y, sobre todo, sus conclusiones han permitido la realización de numerosas rehabilitaciones, tanto en inmuebles de prestigio como en edificaciones modestas: - El empleo de un mortero cuyos componentes sean más cercanos a los materiales antiguos. - Una aplicación puramente manual. - Una proporción establecida a fin de proteger de las aguas de desagüe los enlucidos de mortero de yeso, las cornisas, molduras y etc. - Muros portantes con las características mecánicas más elevadas que las de los enlucidos.

Surface Activity Interactions in Aqueous Solution of Anionic Surfactants with a Water Treatment Protein from Moringa oleifera Seeds  [PDF]
Habauka M. Kwaambwa, Raymond Maikokera, Fiona M. Nermark
Green and Sustainable Chemistry (GSC) , 2015, DOI: 10.4236/gsc.2015.51005
Abstract: The interaction of anionic surfactants sodium dodecylbenzenesulphonate (SDBS) and sodium bis (2-ethyl-1-hexylsulfosuccinate) (AOT) with the water treatment protein extracted from Moringa oleifera seeds has been investigated by surface tension measurements. The results were compared with previously reported studies using surface tension and zeta potential measurements of the same protein with an anionic surfactant sodium dodecylsulphate. There is a strong electrostatic interaction between the protein and the surfactants characterized by a local maximum at intermediate surfactant concentration. This surfactant concentration depends on the protein concentration and corresponds to the surfactant concentration at the point of charge reversal (zeta potential = 0 mV). The number of surfactant molecules required to neutralize the positive charges on the protein was found to be 8 per protein molecule.
