Context and models for the analysis of individual and group needs

This paper summarizes the papers presented in the thematic stream Models for the Analysis of Individual and Group Needs, at the 2007 IAEVG-SVP-NCDA Symposium: Vocational Psychology and Career Guidance Practice: An International Partnership. The predominant theme which emerged from the papers was that theory and practice need to be positioned within their contexts. For this paper, context has been formulated as a dimension ranging from the individual’s experience of himself or herself in conversations, including interpersonal transactions and body culture, through to broad higher levels of education, work, nation, and economy.

Validation of the Algase Wandering Scale (Version 2) in a cross cultural sample

This study examined the psychometric properties of an expanded version of the Algase Wandering Scale (Version 2) (AWS-V2) in a cross-cultural sample. A cross-sectional survey design was used. Study subjects were 172 English-speaking persons with dementia (PWD) from long-term care facilities in the USA, Canada, and Australia. Two or more facility staff rated each subject on the AWS-V2. Demographic and cognitive data (MMSE) were also obtained. Staff provided information on their own knowledge of the subject and of dementia. Separate factor analyses on data from two samples of raters each explained greater than 66% of the variance in AWS-V2 scores and validated four (persistent walking, navigational deficit, eloping behavior, and shadowing) of five factors in the original scale. Items added to create the AWS-V2 strengthened the shadowing subscale, failed to improve the routinized walking subscale, and added a factor, attention shifting as compared to the original AWS. Evidence for validity was found in significant correlations and ANOVAs between the AWS-V2 and most subscales with a single item indicator of wandering and with the MMSE. Evidence of reliability was shown by internal consistency of the AWS-V2 (0.87, 0.88) and its subscales (range 0.88 to 0.66), with Kappa for individual items (17 of 27 greater than 0.4), and ANOVAs comparing ratings across rater groups (nurses, nurse aids, and other staff). Analyses support validity and reliability of the AWS-V2 overall and for persistent walking, spatial disorientation, and eloping behavior subscales. The AWS-V2 and its subscales are an appropriate way to measure wandering as conceptualized within the Need-driven Dementia-compromised Behavior Model in studies of English-speaking subjects. Suggestions for further strengthening the scale and for extending its use to clinical applications are described.

PLAStiCC: Predictive Look-Ahead Scheduling for Continuous dataflows on Clouds

Scalable stream processing and continuous dataflow systems are gaining traction with the rise of big data due to the need for processing high velocity data in near real time. Unlike batch processing systems such as MapReduce and workflows, static scheduling strategies fall short for continuous dataflows due to the variations in the input data rates and the need for sustained throughput. The elastic resource provisioning of cloud infrastructure is valuable to meet the changing resource needs of such continuous applications. However, multi-tenant cloud resources introduce yet another dimension of performance variability that impacts the application's throughput. In this paper we propose PLAStiCC, an adaptive scheduling algorithm that balances resource cost and application throughput using a prediction-based lookahead approach. It not only addresses variations in the input data rates but also the underlying cloud infrastructure. In addition, we also propose several simpler static scheduling heuristics that operate in the absence of accurate performance prediction model. These static and adaptive heuristics are evaluated through extensive simulations using performance traces obtained from Amazon AWS IaaS public cloud. Our results show an improvement of up to 20% in the overall profit as compared to the reactive adaptation algorithm.

FleSSR project: Sustainable business models for community cloud infrastructure in the UK higher education sector

Cloud-based infrastructure essentially comprises two offerings, cloud-based compute and cloud-based storage. These are perhaps best typified for most people by the two main components of the Amazon Web Services (AWS)1 public cloud offer, the Elastic Compute Cloud (EC2)2 and the Simple Storage Service (S3)3, though, of course, there are many other related services offered by Amazon and many other providers of similar public cloud infrastructure across the Internet.

An integrated wideband multifunctional antenna using a microstrip patch with two U-slots

In this paper a multifunctional microstrip antenna is designed, fabricated and experimentally verified for operation in AWS, GSM, WiMAX and WLAN bands. This microstrip patch antenna has two U-shaped slots to achieve the dual wideband operation required to meet these specifications. The dimensions and locations of the U-slots are designed appropriately. The thick substrate used here helps in integrating the antenna with the existing aircraft panel material while achieving wide bandwidths. Experimental results of this single feed antenna indicate that it meets all current requirements for in-cabin wireless communication needs.

Compact dual band slot loaded circular microstrip antenna with a superstrate

Design of a compact dual frequency microstrip antenna is presented. The structure consists of a slotted circular patch with a dielectric superstrate. The superstrate,not only acts as a radome, but improves the bandwidth and lowers the resonant frequency also. The proposed design provides an overall size reduction of about 60% compared to an unslotted patch along with good efficiency,gain and bandwidth. The polarization planes at the two resonances are orthogonal and can be simultaneously excited using a coaxial feed. Parametric study of this configuration showed that the frequency ratio of the two resonances can be varied from 1.17 to 1.7 enabling its applications in the major wireless communication bands like AWS, DECT,PHS,Wi.Bro, ISM,and DMB. Design equations are also deduced for the proposed antenna and validated.

A Quasi-Omnidirectional Antenna for Modern Wireless Communication Gadgets

A compact, planar, wideband antenna designed by modifying the coplanar waveguide is presented in this letter. The proposed antenna finds a wide range of applications including advanced wireless systems (AWS), DCS-1800, DCS-1900/PCS/PHS, WiBro, BlueTooth/WLAN/WiBree/ZigBee, DMB, Global Star Satellite Phones, and digital cordless phones. Wide bandwidth > 75% centered at 2.50 GHz, quasi-omnidirectional radiation coverage along with moderate gain and efficiency are the salient features of the antenna. A prototype fabricated on a substrate with dielectric constant 4.4 and thickness 1.6 mm occupies an area of (31times 64) mm2. Details of antenna design and discussions on the effect of various antenna parameters on the radiation characteristics are presented.

Plan de Manejo de Conflictos Socioambientales en las comunidades indígenas de la zona norte de la Provincia de Esmeraldas: comunidad Awá

La presente investigación analiza el conflicto y la identidad en la lucha por la tierra, desde la comprensión de las lógicas culturales frente a la tierra. Permitiendo entender las motivaciones simbólicas de cada grupo frente a la tierra y sobre todo valorar el hecho de que existen grupos para quienes la tierra tiene un valor más allá de lo económico y monetario. Su valoración radica en que se constituye en un espacio de vida y reproducción socio cultural para el grupo que lo habita. Existe un conflicto de carácter étnico, ambiental y económico. Es decir, los intereses entre la adjudicación del territorio en donde se desarrolla las actividades de extracción, explotación, venta y comercialización de maderera, la conservación del medio ambiente y los derechos territoriales de la población Awá. Las actividades madereras, palmicultora y minera se han caracterizado por ser altamente contaminantes, por ser un motor de colonización y por haber provocado numerosos conflictos no sólo en la zona, sino a nivel nacional. Las principales amenazas sobre la integridad del territorio vienen por parte de las empresas madereras y palmicultoras. Ya que el territorio Awá posee la última extensión de bosque primario que queda en la costa del Ecuador. Como la madera, se está terminando en otras partes, los intereses de los grandes industriales madereros van hacia la madera que se tiene en esta zona. El resultado de las negociaciones todavía no se ha dado, por cuanto se espera respuesta por parte de entidades públicas que reconozcan el derecho de la comunidad Awá que tiene su territorio en disputa como en conservar sus recursos naturales y redistribuir sus ingresos a toda la comunidad. Finalmente, la investigación demuestra que un manejo adecuado del conflicto, es decir entre iguales, con metodologías participativas, permitirá soluciones adecuadas además, es posible ir creando procesos sociales basados en el respecto mutuo y la interculturalidad.

El territorio del pueblo indígena Awá de Colombia a través de una interpretación jurídico crítica

La presente investigación: “El territorio del pueblo indígena Awá de Colombia a través de una interpretación jurídico crítica,” se propone indagar desde una perspectiva y análisis socio-jurídico crítico, la problemática del acceso real de la comunidad indígena Awá al derecho colectivo fundamental del territorio y su efectivización, como expresión de los derechos humanos indígenas consagrados en la Constitución Política de Colombia de 1991. A lo largo del desarrollo de los capítulos se pretende vincular el contexto social y político, al análisis ideológico de los discursos jurídicos hegemónicos, las estructuras y dispositivos de poder y el colonialismo, que aún prevalece y dominan el ordenamiento jurídico, y la institucionalidad jurídico gubernamental y administrativa, que son las llamadas a efectivizar en la práctica cotidiana los derechos colectivos de los pueblos indígenas. El trabajo se divide en cuatro capítulos. En el capítulo primero se describe la perspectiva social y filosófica sobre el territorio dentro de la cosmovisión indígena Awá. En el segundo capítulo se aborda el territorio en la dimensión valorativa, pragmática y jurisprudencial dentro de la evolución histórica de la visión hegemónica colonial, hasta los avances posteriores a la Constitución de 1991. En el tercer capítulo se realizará un breve recuento sobre las diversas problemáticas de contexto que originan la desterritorialización del pueblo Awá y controvierten la efectividad de los derechos colectivos indígenas consagrados en el ordenamiento jurídico del Estado social de derecho Colombiano. En el cuarto capítulo se dimensiona desde una óptica política e histórica los factores y contradiciones más importantes de carácter estructural, que inciden objetivamente en el acceso, respeto y garantía del derecho al territorio de las comunidades indígenas tomando como centro al pueblo Awá. Finalmente, se analizan las tensiones vigentes entre el derecho colectivo al territorio consagrado en el ordenamiento jurídico colombiano y la cosmovisión Awá, aunado a los factores políticos e ideológicos y las problemáticas estructurales que impiden su real efectivización.

Extraction of compounds associated with water repellency in sandy soils of different origin

After an initial evaluation of several solvents, the efficiency of Soxhlet extractions with isopropanol/ammonia (s.g. 0.88) (70 : 30 v : v; 24 h) in extracting compounds associated with water repellency in sandy soils was examined using a range of repellent and wettable control soils (n = 15 and 4) from Australia, Greece, Portugal, The Netherlands, and the UK. Extraction efficiency and the role of the extracts in causing soil water repellency was examined by determining extract mass, sample organic carbon content and water repellency (after drying at 20°C and 105°C) pre- and post-extraction, and amounts of aliphatic C–H removed using DRIFT, and by assessing the ability of extracts to cause repellency in acid-washed sand (AWS).

Key findings are: (i) none of organic carbon content, amount of aliphatic C–H, or amount of material extracted give any significant correlation with repellency for this diverse range of soils; (ii) sample drying at 105°C is not necessarily useful before extraction, but may provide additional information on extraction effectiveness when used after extraction; (iii) the extraction removed repellency completely from 13 of the 15 repellent samples; (iv) extracts from all repellent and wettable control soils were capable of inducing repellency in AWS. The findings suggest that compounds responsible for repellency represent only a fraction of the extract composition and that their presence does not necessarily always cause repellency.

Efeito da aplicação foliar de silício em rúcula cultivada em dois tipos de solos

The rocket is a leafy herbaceous annual, features small size, rapid vegetative growth and short life cycle. Silicon is considered a beneficial element, and despite not having his definition of essential mineral nutrition of plants has been widely used in research. The objective was to assess the effect of foliar fertilization with silicon levels in soils in the cultivation of the rocket. The experiment was conducted in a greenhouse in the DRN / Soil Science, UNESP / FCA, Botucatu-SP, from April 15 to May 20, 2008. The experimental design was randomized blocks in factorial 2x5 (two solos and five doses of silicon). At the end of the experiment, evaluated at the point of harvest to plant height (cm), leaf area (LA), total fresh mass (TFM), total dry matter (TDM), leaf area ratio (LAR), specific weight Leaf (PEF), amount of water in the shoot (AWS) and content and accumulation of silicon in the leaves. It was concluded that silicon had no influence on the agronomic characteristics of the rocket and changes were only to soil type.
