Speech therapy after stroke: trial shows only that practice varies

Bowen and colleagues’ methods and conclusions raise concerns.1 At best, the trial evaluates the variability in current practice. In no way is it a robust test of treatment. Two communication impairments (aphasia and dysarthria) were included. In the post-acute stage spontaneous recovery is highly unpredictable, and changes in the profile of impairment during this time are common.2 Both impairments manifest in different forms,3 which may be more or less responsive to treatment. A third kind of impairment, apraxia of speech, was not excluded but was not targeted in therapy. All three impairments can and do co-occur. Whether randomised controlled trial designs can effectively cope with such complex disorders has been discussed elsewhere.4 Treatment was defined within terms of current practice but was unconstrained. Therefore, the treatment group would have received a variety of therapeutic approaches and protocols, some of which may indeed be ineffective. Only 53% of the contact time with a speech and language therapist was direct (one to one), the rest was impairment based therapy. In contrast, all of the visitors’ time was direct contact, usually in conversation. In both groups, the frequency and length of contact time varied. We already know that the transfer from impairment based therapy to functional communication can be limited and varies across individuals.5 However, it is not possible to conclude from this trial that one to one impairment based therapy should be replaced. For that, a well defined impairment therapy protocol must be directly compared with a similarly well defined functional communication therapy, with an attention control.

The Haptic Aesthetic in Samuel Beckett's Drama

In their sparse and isolated spaces, Samuel Beckett's figures imagine the touch of a lost love or dream of the comfort and care that the hands of a dear one might bring. Applying philosophical writings that feature sensation, particularly touch, this study examines how Beckett's later work for stage and screen dramatizes moments of contact between self and self, self and world, and self and other. With implications for how gender and ethics can be approached within Beckett's aesthetic, this study explores the employment of haptic imagery as an alternative to certain dominant codes of visual representation.

Adaptive communication: languages with more non-native speakers tend to have fewer word forms

Explaining the diversity of languages across the world is one of the central aims of typological, historical, and evolutionary linguistics. We consider the effect of language contact-the number of non-native speakers a language has-on the way languages change and evolve. By analysing hundreds of languages within and across language families, regions, and text types, we show that languages with greater levels of contact typically employ fewer word forms to encode the same information content (a property we refer to as lexical diversity). Based on three types of statistical analyses, we demonstrate that this variance can in part be explained by the impact of non-native speakers on information encoding strategies. Finally, we argue that languages are information encoding systems shaped by the varying needs of their speakers. Language evolution and change should be modeled as the co-evolution of multiple intertwined adaptive systems: On one hand, the structure of human societies and human learning capabilities, and on the other, the structure of language.

POSTMARITAL RESIDENCE PRACTICE IN SOUTHERN BRAZILIAN COASTAL GROUPS: CONTINUITY AND CHANGE

The coastal plains of the States of Parana and Santa Catarina, in Southern Brazil, were first settled around 6000 B.P. by shellmound builders, a successful fisher-hunter-gatherer population that inhabited the coastal lowlands practically unchanged for almost five thousand years. Shellmounds were typically occupied as residential sites as well as cemeteries, and are usually associated with rich alimentary zones. Around 1200 B.P., the first evidence of ceramics brought from the interior is found in coastal areas, and together with ceramics there is a progressive abandonment of shellmound construction in favor of flat cold shallow sites. Here we consider if these changes were reflected in the postmarital residence practice of coastal groups, i.e., if the arrival or intensification of contact with groups from the interior resulted in changes in this aspect of social structure among the coastal groups. To test the postmarital residence practice we analyzed within-group variability ratios between males and females, following previous studies on the topic. and between-group, correlations between Mahalanobis distances and geographic distances. The results suggest that in the pre-ceramic series a matrilocal, postmarital residential system predominated, while in the ceramic period there was a shift toward patrilocality. This favors the hypothesis that the changes experienced by coastal groups after 1200 B.P. affected not only their economy and material culture, but important aspects of their sociopolitical organization as well.

Motstånd och stöd : en studie av svenska muslimska församlingar

Opposition and Support: A Study of Swedish Muslim Congregations Anti-Islamic attitudes are deeply rooted in Western Europe, and Muslims have, especially in the post-September 11 context, experienced discrimination and demonization. But how do anti-Islamic attitudes affect practicing Muslims and their congregations? The aim of this study, the first of its kind in Europe, is to present a statistically representative view of how Muslim congregations in Sweden experienced the reactions from the surrounding community. The results of the survey carried out show that according to the representatives of the local congregations (n=105) half of the congregations have experienced opposition from the local community and in 40 percent of the congregations criminal offences have been committed against active Muslims or their places of worship.  This opposition is closely connected with two types of situations: either international occurrences (i.e. terrorist bombings in, for example, London, Madrid) or local events that have emphasized the presence of Islam in the public sphere. A multivariate analysis of the results of the study shows that the strongest opposition has taken place in small municipalities with a large proportion of immigrants. However, opposition does not preclude support. On the contrary, opposition appears to have a mobilizing effect on those who support the right of Muslims to exercise freedom of religion. However, neither opposition nor support are the key factors affecting whether congregations see themselves as established in the local community. The degree of anchorage depends on the demographic composition of the congregation and on the degree of contact that the members have with the surrounding community.

Reuse-based test planning for core-based systems-on-chip

Electronic applications are currently developed under the reuse-based paradigm. This design methodology presents several advantages for the reduction of the design complexity, but brings new challenges for the test of the final circuit. The access to embedded cores, the integration of several test methods, and the optimization of the several cost factors are just a few of the several problems that need to be tackled during test planning. Within this context, this thesis proposes two test planning approaches that aim at reducing the test costs of a core-based system by means of hardware reuse and integration of the test planning into the design flow. The first approach considers systems whose cores are connected directly or through a functional bus. The test planning method consists of a comprehensive model that includes the definition of a multi-mode access mechanism inside the chip and a search algorithm for the exploration of the design space. The access mechanism model considers the reuse of functional connections as well as partial test buses, cores transparency, and other bypass modes. The test schedule is defined in conjunction with the access mechanism so that good trade-offs among the costs of pins, area, and test time can be sought. Furthermore, system power constraints are also considered. This expansion of concerns makes it possible an efficient, yet fine-grained search, in the huge design space of a reuse-based environment. Experimental results clearly show the variety of trade-offs that can be explored using the proposed model, and its effectiveness on optimizing the system test plan. Networks-on-chip are likely to become the main communication platform of systemson- chip. Thus, the second approach presented in this work proposes the reuse of the on-chip network for the test of the cores embedded into the systems that use this communication platform. A power-aware test scheduling algorithm aiming at exploiting the network characteristics to minimize the system test time is presented. The reuse strategy is evaluated considering a number of system configurations, such as different positions of the cores in the network, power consumption constraints and number of interfaces with the tester. Experimental results show that the parallelization capability of the network can be exploited to reduce the system test time, whereas area and pin overhead are strongly minimized. In this manuscript, the main problems of the test of core-based systems are firstly identified and the current solutions are discussed. The problems being tackled by this thesis are then listed and the test planning approaches are detailed. Both test planning techniques are validated for the recently released ITC’02 SoC Test Benchmarks, and further compared to other test planning methods of the literature. This comparison confirms the efficiency of the proposed methods.

A Adoção das Estratégicas de CRM e a Fidelização do Cliente

As relações comerciais observadas no início do século passado se baseavam no atendimento personalizado, em que cada cliente era recebido pessoalmente pelo dono da loja, que por sua vez conhecia a clientela e suas principais necessidades. Com a massificação da produção e o surgimento dos grandes magazines e shopping centers, o foco das empresas se voltou para produtos e serviços, futor que promoveu o distanciamento das relações com os clientes, tornando-os ilustres desconhecidos para as empresas. Quase um século depois, o advento da Internet prOpICIOU um processo de reaproximação entre empresas e clientes, eis que as fronteiras geográficas começaram a desaparecer, as empresas locais começaram a atuar e concorrer mundialmente através da web, o mercado apresentou-se mais competitivo e os clientes conquistaram maior poder de escolha e se tornaram mais voláteis. Neste contexto de grandes massas, surge o CRM contemplando um conjunto de estratégias que permeiam toda a organização, como por exemplo, a revisão dos processos de negócios, a mudança da cultura com o foco no cliente, a automação dos serviços de marketing, vendas e atendimento, a disponibilização de multi-canais de contato com o cliente e a integração das bases de dados com os canais de interação. As estratégias de CRM, com base na revisão dos processos de negócios, na mudança da cultura organizacional e na infra-estrutura tecnológica, objetivam estabelecer relações individualizadas com uma imensa massa de clientes. Neste sentido, esse trabalho de pesquisa intenciona aprofundar os conhecimentos sobre influência do CRM na fidelização do cliente.

Implementação de CRM para viabilização de marketing de relacionamento: um estudo de caso

Foco em estratégias empresariais para a longevidade da relação com clientes, comunicação personalizada bidirecional, múltiplos pontos de contato, novas formas de segmentação de mercado, estrutura organizacional descentralizada e mensuração em tempo real da satisfação dos clientes, são exemplos que indicam a existência de uma forma de marketing diferenciada, denominada de marketing de relacionamento. Motivada pela crescente demanda empresarial por tecnologias mercadológicas, a indústria de softwares criou, em meados dos anos 90, um sistema denominado de Customer Relationship Management (CRM) com a promessa de gerenciar, de forma integrada, todos os relacionamentos com os clientes. Gradativamente, novas funcionalidades foram incorporadas ao sistema que alcançou ampla difusão no meio empresarial, responsável por investimentos na ordem de bilhões de dólares ao ano. Enquanto os fabricantes de CRM anunciam crescimentos significativos de vendas, o mercado vem apresentando sinais de insatisfação. Há dúvidas se a implementação do sistema seria suficiente para viabilizar o marketing de relacionamento e quais são seriam suas potencialidades. Pesquisar a teoria do marketing de relacionamento, levantar qUaiS são os seus elementos determinantes e investigar as possibilidades do CRM poderá contribuir para proporclOnar beneficios mútuos para as quatro partes envolvidas no relacionamento: os clientes, as empresas que comercializam produtos e serviços, fabricantes e implementadores de CRM.

O novo federalismo social e o Rio: desenho de programas complementares de transferência de renda condicionada

Brazilian public policy entered in the so-called new social federalism through its conditional cash transfers. States and municipalities can operate together through the nationwide platform of the Bolsa Familia Program (BFP), complementing federal actions with local innovations. The state and the city of Rio de Janeiro have created programs named, respectively, Renda Melhor (RM) and Família Carioca (FC). These programs make use of the operational structure of the BFP, which facilitates locating beneficiaries, issuing cards, synchronizing payment dates and access passwords and introducing new conditionalities. The payment system of the two programs complements the estimated permanent household income up to the poverty line established, giving more to those who have less. Similar income complementation system was subsequently adopted in the BFP and the Chilean Ingreso Ético Familiar, which also follow the principle of estimation of income used in the FC and in the RM. Instead of using the declared income, the value of the Rio cash transfers are set using the extensive collection of information obtained from the Single Registry of Social Programs (Cadastro Único): physical configuration of housing, access to public services, education and work conditions for all family members, presence of vulnerable groups, disabilities, pregnant or lactating women, children and benefits from other official transfers such as the BFP. With this multitude of assets and limitations, the permanent income of each individual is estimated. The basic benefit is defined by the poverty gap and priority is given to the poorest. These subnational programs use international benchmarks as a neutral ground between different government levels and mandates. Their poverty line is the highest of the first millennium goal of the United Nations (UN): US$ 2 per person per day adjusted for the cost of living. The other poverty line of the UN, US$ 1.25, was implicitly adopted as the national extreme poverty line in 2011. The exchange of methodologies between federal entities has happened both ways. The FC began with the 575,000 individuals living in the city of Rio de Janeiro who were on the payroll of the BFP. Its system of impact evaluation benefited from bi-monthly standardized examinations. In the educational conditionalities, the two programs reward students' progress, a potential advantage for those who most need to advance. The municipal program requires greater school attendance than that of the BFP and the presence of students’ parents at the bimonthly meetings held on Saturdays. Students must achieve a grade of 8 or improve at least 20% in each exam to receive a bi-monthly premium of R$50. In early childhood, priority is given to the poor children in the program Single Administrative Register (CadÚnico) to enroll in kindergarten, preschools and complementary activities. The state program reaches more than one million people with a payment system similar to the municipal one. Moreover, it innovates in that it transfers awards given to high school students to savings accounts. The prize increases and is paid to the student, who can withdraw up to 30% annually. The total can reach R$3,800 per low-income student. The State and the city rewarded already education professionals according to student performance, now completing the chain of demand incentives on poor students and their parents. Increased performance is higher among beneficiaries and the presence of their guardians at meetings is twice compared to non beneficiaries; The Houston program, also focuses on aligning the incentives to teachers, parents and students. In general, the plan is to explore strategic complementarities, where the whole is greater than the sum of its parts. The objective is to stimulate, through targets and incentives, synergies between social actors (teachers, parents, students), between areas (education, assistance, work) and different levels of government. The cited programs sum their efforts and divide labor so as to multiply interactions and make a difference in the lives of the poor.

Comportamento de compra dos consumidores num ambiente multicanal : o caso de um grande varejista brasileiro

Nas últimas décadas, o varejo passou por várias transformações. Depois da popularização da internet, muitas mudanças ocorreram, como o crescimento dos canais virtuais e a mudança de papel das lojas físicas. Essas mudanças impactaram diretamente no comportamento de compra do consumidor, que passou a ter vários pontos de contato com o varejista. O presente trabalho visa refinar, no cenário brasileiro, o artigo de Schröder e Zaharia (2008), que analisa as Orientações para Compras dos consumidores (Conveniência, Independência, Recreação e Aversão ao Risco) e como essas Orientações para Compra influenciam na escolha, por parte dos consumidores, dos canais de pesquisa e compra de um varejista. Por meio do estudo de caso, com um grande varejista multicanal brasileiro, foi feita pesquisa junto aos seus consumidores para avaliar como as Orientações para Compra influenciam o comportamento de compra e a escolha pelos canais a serem utilizados. Acredita-se que com os achados obtidos, poderão contribuir, no cenário acâdemico, para o melhor entendimento do impacto das Orientações para Compra no comportamento de compra do consumidor, nesse ambiente em transformação; e, com relação ao cenário gerencial, colaborar com o varejo, demonstrando que o uso das Orientações para Compras, na melhoria dos processos e desenvolvimento dos canais de contato com os consumidores, pode impactar de forma positiva o relacionamento com o cliente, possibilitando atender as suas necessidades e aumentar sua fidelidade.

Estudo da viabilidade do sistema LZAS para uso como selante de PaCOS

Cells the solid oxide fuel are systems capable to directly convert energy of a chemical reaction into electric energy in clean, quiet way and if its components in the solid state differentiate of excessively the techniques for having all. Its more common geometric configurations are: the tubular one and to glide. Geometry to glide beyond the usual components (anode, cathode and electrolyte) needs interconnect and sealant. E the search for materials adjusted for these components is currently the biggest challenge found for the production of the cells. The sealants need to present chemical stability in high temperatures, to provoke electric isolation, to have coefficient of compatible thermal expansion with the excessively component ones. For presenting these characteristics the glass-ceramics materials are recommended for the application. In this work the study of the partial substitution of the ZrO2 for the Al2O3 in system LZS became it aiming at the formation of system LZAS, this with the addition of natural spodumene with 10, 20 and 30% in mass. The compositions had been casting to a temperature of 1500°C and later quickly cooled with the objective to continue amorphous. Each composition was worn out for attainment of a dust with average diameter of approximately 3μm and characterized by the techniques of DRX, FRX, MEV, dilatometric analysis and particle size analysis. Later the samples had been conformed and treated thermally with temperatures in the interval between 700-1000 °C, with platform of 10 minutes and 1 hour. The analyses for the treated samples had been: dilatometric analysis, DRX, FRX, electrical conductivity and tack. The results point with respect to the viability of the use of system LZAS for use as sealant a time that had presented good results as isolating electric, they had adhered to a material with similar α of the components of a SOFC and had presented steady crystalline phases

Avaliação de produtos naturais no controle de biofilmes formados em sistema dinâmico

The biofilms microbial forms of association are responsible for generating, accelerating and / or induce the process of corrosion. The damage generated in the petroleum industry for this type of corrosion is significatives, representing major investment for your control. The aim of this study was to evaluate such tests antibiograms the effects of extracts of Jatropha curcas and essential oil of Lippia gracilis Schauer on microrganisms isolated from water samples and, thereafter, select the most effective natural product for further evaluation of biofilms formed in dynamic system. Extracts of J. curcas were not efficient on the complete inhibition of microbial growth in tests type antibiogram, and essential oil of L. gracilis Schauer most effective and determined for the other tests. A standard concentration of essential oil of 20 μL was chosen and established for the evaluation of the biofilms and the rate of corrosion. The biocide effect was determined by microbial counts of five types of microorganisms: aerobic bacteria, precipitating iron, total anaerobic, sulphate reducers (BRS) and fungi. The rate of corrosion was measured by loss of mass. Molecular identification and scanning electron microscopy (SEM) were performed. The data showed reduction to zero of the most probable number (MPN) of bacteria precipitating iron and BRS from 115 and 113 minutes of contact, respectively. There was also inhibited in fungi, reducing to zero the rate of colony-forming units (CFU) from 74 minutes of exposure. However, for aerobic and anaerobic bacteria there was no significant difference in the time of exposure to the essential oil, remaining constant. The rate of corrosion was also influenced by the presence of oil. The essential oil of L. gracilis was shown to be potentially effective

Banheiros Públicos: Os bastidores das práticas sexuais

This dissertation tries to describe the interactions called pegações in the homosexual milieu that exist in the public bathrooms in UFRN. They used for sexual practices by some of their users. The participating observation made it possible a discription concerning how the interactions occur among the bathrooms users. We researched the flert process that happens around the place, the poses they strike, the approach, until they get to the sexual practice. We also traced their route through the most used bathrooms. We associated the research the messages written on the doors and cabins that are means of contact among the users. So we tried to interpret the meanings of the interactions that exist in the public bathrooms in UFRN

Efeito de Colletotrichum dematium var. truncata e Cercospora kikuchii na germinação de sementes de soja

A antracnose, causada por Colletotrichum dematium var. truncata, é a principal doença da soja que afeta a fase inicial de formação das vagens, podendo causar a morte das plântulas. Cercospora kikuchii é o fungo causador da doença mancha púrpura nas sementes de soja, responsável por severas reduções no rendimento e na qualidade das sementes. O objetivo deste trabalho foi determinar o tempo mais apropriado para infecção das sementes de soja por C. dematium var. truncata e C. kikuchii, para posterior avaliação dos danos causados pelo fungo na germinação. Tais fungos foram cultivados em meio BDA. As sementes de soja cultivar MSOY 6101 foram colocadas sobre meio contendo o patógeno C. dematium var. truncata por 0 (testemunha), 4, 16, 24, 32 e 40h. As sementes da cv. CD 208 foram inoculadas com C. kikuchii pelos mesmos períodos citados, com adição de 48 e 56h. Após os respectivos tempos de contato, as sementes foram submetidas ao teste de sanidade (papel de filtro), com duas variações, sem e com assepsia superficial (hipoclorito de sódio 1% por três minutos). Determinado o tempo mais adequado de infecção, outras sementes foram infectadas pelo patógeno e, posteriormente, foram realizados testes de germinação em papel e areia com uma mistura de sementes sadias (colocadas sobre o meio BDA) e sementes inoculadas, resultando em lotes com 0, 20, 40, 60, 80 e 100% de sementes infectadas. O tempo de incubação de 40 e 56 horas para C. dematium var truncata e C. Kikuchii, respectivamente são suficientes para obtenção da totalidade das sementes infectadas. C. Kikuchii não prejudica a germinação das sementes.
