Effect of changing data collection parameters on statistical motor unit number estimates

The effect of number of samples and selection of data for analysis on the calculation of surface motor unit potential (SMUP) size in the statistical method of motor unit number estimates (MUNE) was determined in 10 normal subjects and 10 with amyotrophic lateral sclerosis (ALS). We recorded 500 sequential compound muscle action potentials (CMAPs) at three different stable stimulus intensities (10–50% of maximal CMAP). Estimated mean SMUP sizes were calculated using Poisson statistical assumptions from the variance of 500 sequential CMAP obtained at each stimulus intensity. The results with the 500 data points were compared with smaller subsets from the same data set. The results using a range of 50–80% of the 500 data points were compared with the full 500. The effect of restricting analysis to data between 5–20% of the CMAP and to standard deviation limits was also assessed. No differences in mean SMUP size were found with stimulus intensity or use of different ranges of data. Consistency was improved with a greater sample number. Data within 5% of CMAP size gave both increased consistency and reduced mean SMUP size in many subjects, but excluded valid responses present at that stimulus intensity. These changes were more prominent in ALS patients in whom the presence of isolated SMUP responses was a striking difference from normal subjects. Noise, spurious data, and large SMUP limited the Poisson assumptions. When these factors are considered, consistent statistical MUNE can be calculated from a continuous sequence of data points. A 2 to 2.5 SD or 10% window are reasonable methods of limiting data for analysis. Muscle Nerve 27: 320–331, 2003

Assessing childrens competence in computer interactions: Preliminary reliability and validity of the test of mouse proficiency

The Test of Mouse Proficiency (TOMP) was developed to assist occupational therapists and education professionals assess computer mouse competency skills in children from preschool to upper primary (elementary) school age. The preliminary reliability and validity of TOMP are reported in this paper. Methods used to examine the internal consistency, test-retest reliability, and criterion- and construct-related validity of the test are elaborated. In the continuing process of test refinement, these preliminary studies support to varying degrees the reliability and validity of TOMP. Recommendations for further validation of the assessment are discussed along with indications for potential clinical application.

API documentation with executable examples

The rise of component-based software development has created an urgent need for effective application program interface (API) documentation. Experience has shown that it is hard to create precise and readable documentation. Prose documentation can provide a good overview but lacks precision. Formal methods offer precision but the resulting documentation is expensive to develop. Worse, few developers have the skill or inclination to read formal documentation. We present a pragmatic solution to the problem of API documentation. We augment the prose documentation with executable test cases, including expected outputs, and use the prose plus the test cases as the documentation. With appropriate tool support, the test cases are easy to develop and read. Such test cases constitute a completely formal, albeit partial, specification of input/output behavior. Equally important, consistency between code and documentation is demonstrated by running the test cases. This approach provides an attractive bridge between formal and informal documentation. We also present a tool that supports compact and readable test cases; and generation of test drivers and documentation, and illustrate the approach with detailed case studies.

Distribution of Sugarcane mosaic virus in sugarcane plants

Variation in the concentration of virus in different parts of the plant has implications for virus-indexing programs. To allow more reliable detection of Sugarcane mosaic virus (SCMV), the distribution of the virus in sugarcane plants after artificial inoculation was studied using a reverse transcription polymerase chain reaction (RT-PCR) assay. Leaves of susceptible and moderately resistant sugarcane were mechanically inoculated with SCMV 6 weeks after planting. Weekly for 8 weeks after inoculation, plants were examined for mosaic symptoms and samples of leaves, roots and tillers were tested by RT-PCR to detect virus. SCMV moved from the point of inoculation to younger leaves, roots and tillers and eventually to leaves that emerged prior to inoculation. The pattern of SCMV distribution in moderately resistant and susceptible cultivars was not substantially different. However, the virus moved more slowly in the moderately resistant than in the susceptible cultivar. Young leaves proved to be the most suitable tissue for testing.

Olhares acerca do processo de construção dos Projetos Políticos Pedagógicos dos cursos Técnicos Integrados ao Ensino Médio de Jovens e Adultos no contexto do Ifes campus Vitória

Este trabalho é resultado da investigação que teve como objetivo analisar o processo de construção dos Projetos Políticos Pedagógicos dos cursos do Proeja no contexto do Ifes campus Vitória. O problema de pesquisa buscou captar os movimentos e as experiências desencadeados nesse processo. No percurso metodológico, com ênfase na pesquisa qualitativa, foi necessário entrelaçar duas abordagens: a etnografia escolar e a pesquisa-ação em função da atuação profissional da pesquisadora no lócus de estudo. Variados instrumentos foram utilizados para levantamento e a produção dos dados, dentre os quais: questionários, entrevistas, diário de campo das observações, pesquisa bibliográfica e documental. Participaram da pesquisa aproximadamente 80 pessoas, entre docentes, alunos e gestores, abordados em contextos específicos: o grupo de formação continuada, a comissão dos projetos, o encontros dos alunos, a reunião intermediária dentre outros. O referencial teórico-metodológico pautado na perspectiva do materialismo histórico dialético embasou toda a trajetória investigativa, em coerência com a base da produção das pesquisas sobre trabalho e educação e por se constituir a referência que fundamenta os princípios estruturantes do currículo integrado na perspectiva da formação humana. Por meio da metáfora dos observatórios, focamos nossas lentes sobre as questões que desafiaram a construção dos projetos políticos pedagógicos e sua coerência com os princípios epistemológicos, políticos e pedagógicos do Proeja. Nesse movimento, diversos olhares foram captados, possibilitando-nos levantar os seguintes resultados: o percurso de construção dos projetos foi marcado por contradições que perpassam todo o processo e que constituíram um debate profícuo que tenciona a gestão pedagógica, administrativa e financeira do Ifes campus Vitória. O movimento se constituiu também em um processo de construção, partilha de saberes e experiências, impulsionado pela busca da apreensão dos sentidos da integração, que contraditoriamente não alcançou seus objetivos, embora não se possa negar os resultados positivos do processo no interior da Instituição. Dessa forma, os desafios para efetivação da formação integrada no Ifes persistem. Ganha centralidade nessa discussão os sujeitos a quem o programa se volta e suas demandas de formação, bem como as condições materiais de oferta dos cursos e de forma especial as condições de envolvimento dos professores com o programa e as reflexões sobre suas práticas.

Efeito da adição de extrato de casca de jabuticaba nas características físico-químicas e sensoriais de queijo petit suisse

A busca pela melhoria da qualidade de vida e a procura por alimentos naturais e funcionais são crescentes. A incorporação de prebióticos e corantes naturais pode agregar valor ao produto, por serem capazes de melhorar sua qualidade e por apresentarem grandes atrativos tecnológicos. Portanto, o objetivo deste trabalho foi avaliar o efeito da adição de prebióticos (inulina e oligofrutose) e corante natural (extrato de casca de jabuticaba) nas características de queijo petit suisse. Foi realizada análise da composição físico-química (extrato seco total, cinzas, proteínas, lipídeos, carboidratos e acidez titulável) logo após o processamento, análise do pH, colorimetria, teor de compostos bioativos e atividade antioxidante em diferentes tempos de armazenamento (0, 7, 14, 21 e 28 dias), análise do teor de fibras alimentares da formulação de queijo petit suisse com maior atividade antioxidante ao final da vida de prateleira e análises microbiológica e sensorial. O queijo petit suisse elaborado foi dividido em cinco formulações, de acordo com a concentração de corante natural incorporado, que foram 0%, 1,5%, 2,0%, 2,5% e 3,0%. Os dados obtidos com as análises realizadas logo após o processamento e análise sensorial foram submetidos à análise de variância e teste de Tukey, os dados obtidos com as análises realizadas em diferentes tempos de armazenamento foram submetidos à análise de variância e estudo do comportamento cinético, e a análise de fibras e microbiológica foi analisada por meio de estatística descritiva. Os valores de extrato seco total, proteínas, lipídeos, cinzas e carboidrato não diferiram significativamente (p>0,05) entre as formulações. A formulação sem adição de corante natural apresentou menor acidez (p≤0,05), e com o aumento da concentração de corante natural, maior foi a acidez do queijo. Os teores de antocianinas, fenólicos totais e capacidade antioxidante foram maiores com o aumento da concentração de corante incorporado, sendo que o teor de antocianinas reduziu com o decorrer do tempo de armazenamento. O valor encontrado de fibras para a formulação contendo 3,0% de corante natural foi baixo, e o produto não apresentou alegação de propriedade funcional. A fim de verificar se o queijo estava próprio para o consumo, foi realizada análise microbiológica para coliformes termotolerantes, estando todas as formulações de queijo petit suisse em condições sanitárias satisfatórias. A análise sensorial foi realizada em duas etapas. Na primeira etapa foi realizado teste de aceitação com avaliação dos atributos cor, sabor, consistência e impressão global, e intenção de compra para todas as formulações com incorporação de corante natural. Na segunda etapa foi realizado o teste de aceitação com informação nutricional do produto para a amostra mais aceita na primeira etapa. Como resultado, foi observado que o atributo cor foi o único que apresentou diferença significativa (p≤0,05) entre as formulações, sendo as mais aceitas com concentração 2,5% e 3,0%. De forma geral, todas as formulações foram bem aceitas, porém, a formulação com maior adição de corante natural foi a que xiii apresentou maiores notas. Assim, o queijo com maior concentração de corante natural foi o utilizado na segunda etapa sensorial, sendo observada influência das informações nos atributos cor e consistência (p≤0,05). Dessa forma, a utilização de prebióticos e corante natural de casca de jabuticaba em queijo petit suisse foi viável por não alterar a composição centesimal do produto, além de conferir ao produto uma coloração atrativa.

Determinação do momento crítico de flambagem lateral com distorção em vigas mistas contínuas de aço e concreto com perfis de alma senoidal

As vigas mistas de aço e concreto estão sendo largamente utilizadas em construções de edifícios e pontes. Ao se combinar o aço com o concreto obtêm-se estruturas mais econômicas, uma vez que se tira proveito das melhores características de cada material. Nas regiões de momento negativo de uma viga mista contínua, a mesa inferior e parte da alma estão comprimidas, se a alma do perfil não tiver rigidez suficiente para evitar a flexão lateral, ela distorcerá gerando um deslocamento lateral e um giro na mesa comprimida, caracterizando um modo de flambagem denominado flambagem lateral com distorção (FLD). O procedimento de verificação à FLD da EN 1994-1-1:2004 originou o método de cálculo da ABNT NBR 8800:2008, entretanto a EN 1994-1-1:2004 não fornece expressão para o cálculo do momento crítico elástico, enquanto a ABNT NBR 8800:2008 prescreve uma formulação proposta por Roik, Hanswille e Kina (1990) desenvolvida para vigas mistas com perfis de alma plana. Embora as normas prescrevam um método de verificação à FLD para vigas mistas com perfis de alma plana, poucos estudos têm sido feitos sobre esse estado-limite. Além disso, tanto a ABNT NBR 8800:2008 quanto as normas internacionais não abordam perfis de alma senoidal. Neste trabalho, foram implementadas análises de flambagem elástica, com auxílio do software ANSYS 14.0 (2011), em modelos de elementos finitos que retratem o comportamento à FLD de vigas mistas de aço e concreto com perfis de alma plana e senoidal. Os modelos numéricos foram constituídos pelo perfil de aço, por uma mola rotacional que restringe parcialmente o giro da mesa superior e uma restrição ao deslocamento lateral, ao longo de todo o comprimento da viga. Os resultados numéricos são comparados com os obtidos pelas formulações de Roik, Hanswille e Kina (1990) e de Hanswille (2002), adaptadas para levar em consideração a corrugação da alma do perfil de aço. Para avaliação das formulações supracitadas e da consistência da modelagem numérica adotada, o momento crítico elástico foi determinado para vigas mistas com perfis de aço de alma plana. Como resultado, um método para o cálculo do momento crítico elástico de vigas mistas de alma senoidal é proposto.

Modelo de escoamento multifásico para estudo da interação onda/sedimento

Modelos de escoamento multifásico são amplamente usados em diversas áreas de pesquisa ambiental, como leitos fluidizados, dispersão de gás em líquidos e vários outros processos que englobam mais de uma propriedade físico-química do meio. Dessa forma, um modelo multifásico foi desenvolvido e adaptado para o estudo do transporte de sedimentos de fundo devido à ação de ondas de gravidade. Neste trabalho, foi elaborado o acoplamento multifásico de um modelo euleriano não-linear de ondas do tipo Boussinesq, baseado na formulação numérica encontrada em Wei et al. (1995), com um modelo lagrangiano de partículas, fundamentado pelo princípio Newtoniano do movimento com o esquema de colisões do tipo esferas rígidas. O modelo de ondas foi testado quanto à sua fonte geradora, representada por uma função gaussiana, pá-pistão e pá-batedor, e quanto à sua interação com a profundidade, através da não-linearidade e de propriedades dispersivas. Nos testes realizados da fonte geradora, foi observado que a fonte gaussiana, conforme Wei et al. (1999), apresentou melhor consistência e estabilidade na geração das ondas, quando comparada à teoria linear para um kh   . A não-linearidade do modelo de ondas de 2ª ordem para a dispersão apresentou resultados satisfatórios quando confrontados com o experimento de ondas sobre um obstáculo trapezoidal, onde a deformação da onda sobre a estrutura submersa está em concordância com os dados experimentais encontrados na literatura. A partir daí, o modelo granular também foi testado em dois experimentos. O primeiro simula uma quebra de barragem em um tanque contendo água e o segundo, a quebra de barragem é simulada com um obstáculo rígido adicionado ao centro do tanque. Nesses experimentos, o algoritmo de colisão foi eficaz no tratamento da interação entre partícula-partícula e partícula-parede, permitindo a evidência de processos físicos que são complicados de serem simulados por modelos de malhas regulares. Para o acoplamento do modelo de ondas e de sedimentos, o algoritmo foi testado com base de dados da literatura quanto à morfologia do leito. Os resultados foram confrontados com dados analíticos e de modelos numéricos, e se mostraram satisfatórios com relação aos pontos de erosão, de sedimentação e na alteração da forma da barra arenosa

Initial performance of maize in response to NPK fertilization combined with Herbaspirillum seropedicae

The inoculation with plant growth-promoting bacteria can be a technological approach useful for increasing the production of maize. The objective of this study was to evaluate the initial performance of maize in response to application of doses of NPK combined with the inoculation of the diazotrophic bacteria Herbaspirillum seropedicae in an greenhouse experiment. The experiment consisted of six fertilizer levels: 0, 25, 50, 75, 100 and 200% of the recommended dose of NPK applied to maize inoculated and non-inoculated with H. seropedicae. At 30 days after the treatment application, the growth characteristics and nutritional status of the plants were evaluated. Plant development was influenced by fertilization, but it was enhanced by combination with the bacteria, which resulted in significant increases in the dry mass of shoots (7%) and leaf area (9%) when compared with non-inoculated plants. The results showed increases in the concentration of N (11%), P (30%) and K (17%) of maize plants in response to bacterial inoculation together with NPK compared with plants that were applied fertilize only. The greater consistency and stability response of the host plant to bacterization in the presence of chemical fertilizer indicate a promissory biotechnological approach for improving the initial growth and adaptation of maize to the cultivation environment.

Capital Intelectual: sua divulgação no setor bancário em Portugal

The importance of intangible resources has increased dramatically in recent years comparing to tangible ones. The economy in which we live is the result of competitive pressures that have imposed the implementation of business at an international level as well as a requirement in the application of sophisticated technologies that allow us to follow this fast evolution. In this age of information and innovation organizations will only survive if they are inserted in a global network of strategic relations, generically called as the network economy by Lev (2003). The service sector has stood out against the more traditional sectors of the economy. The intensive use of knowledge and a strong customer orientation created a new reality in today’s organizations: a growing importance attached to innovation, to the quality of products and services offered, to the information and communication technologies adopted, and to the creativity and particular abilities of human resources. The concept of intangible assets is more common in an accounting language and intellectual capital is most often applied in the context of management, being associated with a more comprehensive, multidimensional approach, representing all the knowledge that the institution owns and that it applies in the form of expertise, the creativity and organizational competencies that lead to innovation and to the sustained attainment of future economic benefits. An analysis of the scope of intellectual capital is fundamental to take more appropriate management decisions so that a more appropriate accounting treatment could be given by the accounting standardization organizations. This study intends to analyse the practices of information disclosure of the intellectual capital in the banking sector in Portugal, complementing the analysis of the disclosure of intangible assets in the context of accounting standards with the disclosure of intellectual capital in the context of organizational management. In particular, our main aims are to identify the extent of disclosure of intellectual capital made by banks in Portugal and also to identify the factors that determine such a disclosure. The disclosure in the context of accounting standards will be studied by checking the disclosure of intangible assets through the items listed in the International Accounting Standard 38 developed by the International Accounting Standards Board. The context of management was analysed by means of creating a voluntary disclosure index based on assumptions of the model Intellectus, developed by the Centro de Investigación sobre la Sociedad del Conocimiento – Instituto de Administración de Empresas (CIC-IADE) of the Universidad Autónoma of Madrid, and of the model Intellectual Capital Statement (made in Europe) (InCaS), both promoted by the European Commission and that we have adapted to the banking sector. When analysing the disclosure of intangible assets based on the context of accounting standards and the voluntary disclosure of intellectual capital, this study has tried to raise awareness about the importance of issuing reports on the intellectual capital as an alternative tool to take management decisions in the existing organizations and reflects the transparency and legitimacy that these institutions seek through a more extensive and more detailed information disclosure of their intellectual capital. Based on a complimentarily of economic theories, together with social and political theories, we tried to check the extent, evolution and tendencies of the compulsory disclosure of intangible assets and of the voluntary disclosure of the intellectual capital analysed in the period 2001-2011. Banks characteristics were also analysed in order to deduce those factors that determine or promote a larger disclosure in this sector. Based on these objectives, we adopted a longitudinal approach to explore the extent and the development of the disclosure of intangible assets as well as the factors that have determined it. Furthermore, we sought to assess the impact of the adoption of IAS 38 in the financial statements of the organizations in this sector. The disclosure index created on the basis of the disclosure requirements stated in IAS 38 from IASB was applied to the consolidated financial statements of the seventeen banks that rendered their statements in Portugal from 2001 to 2009. Since the information disclosed in the context of accounting standards may not have an important role as a management tool once it was not able to reflect what really contributes to the competitiveness and organizational growth, the voluntary disclosure of the intellectual capital was analysed according to the information obtained from the 2010 annual individual reports of the banks operating in Portugal in that year and from their respective websites in 2011. We tried to analyse the extent of the voluntary disclosure of the intellectual capital and of each of its components, human capital, structural capital and relational capital. The comparative analysis of their annual reports and their web pages allowed us to assess the incidence of the disclosure and discover what channel the banking sector focuses on when disclosing their intellectual capital. Also in this analysis the study of the disclosure determinants has allowed us to conclude about the influence of particular characteristics in the voluntary disclosure of the intellectual capital. The results of the analysis to the extent of the disclosure of intangible assets in the consolidated financial statements of the banking groups in Portugal in the period 2001-2009 have shown an average information disclosure of 0.24. This information disclosure evolved from an average value of 0.1940 in 2001 to 0.2778 in 2009. The average value is 0.8286 if it is only considered the disclosure of the intangible assets that the banks possessed. The evolution of this index means an increase in the average disclosure from 0.7852 in 2001 to 0.8788 in 2009. From the first results that are related to the extent of the disclosure of intangible assets in the financial statements, we can verify that the banking groups present a low disclosure level of these resources. However, when considering the disclosure of only the intangible assets that each institution owns, the disclosure level appears to be in compliance with the disclosure requirements for this sector. An evolution in the disclosure of intangible assets for the period considered was confirmed, showing an increase in the information disclosure of intangible assets in 2005, the year in which the accounting rules for intangible assets changed. The analysis that focused on the disclosure in the context of management tried to understand the extent, the incidence and the determinants of the voluntary information disclosure of intellectual capital in the annual reports of 2010 and on their web pages in 2011, studying the 32 banks operating in Portugal in this period. The average voluntary disclosure of the intellectual capital in the 2010 annual reports is 0.4342 while that in web pages is 0.2907. A review of the components of the intellectual capital allowed us to assess the importance that the banks confer to each of these components. The data obtained show that the relational capital, and more specifically the business capital, is the most disclosed component by banks in Portugal both in the annual reports and in their institutional web pages, followed by the structural capital and, finally, by the human capital. The disclosure of the human capital and the structural capital is higher in the annual reports than that in the websites, while the relational capital is more disclosed in the websites than in the annual reports. The results have also shown that the banks make a complementary use of both sources when disclosing information about their structural capital and relational capital but they do not show any information about their human capital in their websites. We tried to prove the influence of factors that could determine the accounting disclosure and the voluntary disclosure of the intellectual capital in this sector. The change in the IASB accounting rules as from January 1st 2005 gave a greater disclosure of accounting information of intangible assets in the financial statements of banks. The bank size and corporate governance measures have statistically proved to have an influence on the extent of the accounting disclosure of intangible assets and on the voluntary disclosure of the intellectual capital. Economic and financial variables such as profitability, operating efficiency or solvency were not determinants of information disclosure. The instability that the banking sector has experienced in economic and financial indicators in recent years as a result of the global financial markets imbalance has worsen indicators such as profitability, efficiency and solvency and caused major discrepancies in the economic situation between banks in Portugal. This empirical analysis has contributed to confront the disclosure required by accounting rules performed in the financial statements of organizations with that performed in the main disclosure media which is available for entities and which is increasingly requested in the process of taking management decisions. It also allowed us to verify whether there is homogeneity between institutions in the fulfilment of the requirements for information disclosure of intangible assets. However, as for voluntary disclosure of intellectual capital, there are large disparities in the disclosure extent between organizations. Regardless of this sector specific characteristics, the voluntary disclosure of intellectual capital made by banks in Portugal follows the trends in other sectors and the practices adopted in other countries, namely regarding the amount of information disclosed, the incidence of the disclosure on the indicators of relational capital and the importance of variables such as size as determinants of disclosure of intellectual capital. For a further knowledge in this field, we created a specific index for the banking sector, considering appropriate indicators for an incisive, comprehensive analysis in order to consider the most relevant indicators of intellectual capital components. Besides, confronting the analysis of disclosure in the context of accounting standards with the study of voluntary disclosure brought a new analysis approach to the research on intellectual capital disclosure. With this study, we have also intended to raise greater awareness of the need for harmonization in the intellectual capital disclosure on the part of the regulatory banking authority by means of a demanding, consistent and transparent report of intellectual capital with simple, clear, objective indicators so that those interested in disclosing intellectual capital information in the organizations in this sector may obtain more harmonized and comparable information. A research on the disclosure quality of intellectual capital, together with the application of other analysis methodologies in this sector, might be a promising approach for future research. Applying the voluntary disclosure index to the same sector in other countries may also contribute to the knowledge of disclosure practices in different geographical environments. We highlight the relevance of further studies contributing to the harmonization and consistency in the presentation of an intellectual capital report so as to enable organizations to disclose the resources that contribute most to their competitiveness and growth.

Perceptions of residents of hosting the “Guimarães 2012 European Capital of Culture”: An ex-ante approach

The European Capital of Culture is an annual mega-event, which can provide a good forum though which to challenge and engage local citizens, thus generating feelings of common citizenship. In addition, it presents an ideal opportunity to promote the restructuring of the hosting urban space. However, the success of both the organization and the city that hosts the cultural event depends on the residents’ commitment towards it, the consistency of the tourism attractions and activities supplied, and the capacity of anticipating and monitoring the evolution of tourists’ preferences. The present study aims to assess the intention to participate and the impacts perceived by residents of Guimarães from hosting one of the 2012 European Capitals of Culture (2012 ECOC) in the ex-ante period (2011). Through a convenience sample of 471 usable surveys applied to the local population, conducted between October and December 2011, we tried to identify some of these potential impacts. According to the results received, 40% of residents had a low or very low knowledge of the cultural program, although only 11% demonstrated no intention of attending any activity during the event. The comparison of the mean scores of the expected 2012 ECOC impacts by gender reveals that the most valued and least valued factors are common to female and male respondents. With regard to the differences between those that intended to attend the event and the ones that did not, expected participants rated positive and negative impact factors more than did the ones that did not intend to attend.

Chemical, morphological, rheological and thermal properties of Solanum lycocarpum phosphorylated starches

The increasing need for starches with specific characteristics makes it important to study unconventional starches and their modifications in order to meet consumer demands. The aim of this work was to study physicochemical characteristics of native starch and phosphate starch of S. lycocarpum. Native starch was phosphated with sodium tripolyphosphate (5-11%) added with stirring. Chemical composition, morphology, density, binding ability to cold water, swelling power and solubility index, turbidity and syneresis, rheological and calorimetric properties were determined. Phosphorus was not detected in the native sample, but the phosphating process produced modified starches with phosphorus contents of 0.015, 0.092 and 0.397%, with the capacity of absorbing more water, either cold or hot. Rheological data showed the strong influence of phosphorus content on viscosity of phosphate starch, with lower pasting temperature and peak viscosity higher than those of native starch. Enthalpy was negatively correlated with the phosphorus content, requiring 9.7; 8.5; 8.1 and 6.4 kJ g-1 of energy for the transition from the amorphous to the crystalline state for the starch granules with phosphorus contents of 0; 0.015; 0.092 and 0.397%, respectively. Cluster analysis and principal component analysis showed that starches with 0.015 and 0.092% phosphorus have similar characteristics and are different from the others. Our results show that the characteristics of phosphate modified S. lycocarpum starch have optimal conditions to meet the demands of raw materials, which require greater consistency in stickiness, combined with low rates of retrogradation and syneresis.

Stability, sustainability and viability of the Portuguese Football Federation

Purpose: to evaluate and study the viability, stability and the ability of the Portuguese Football Federation (PFF) to generate sustained profits. Methodology: Data were collected based on the Audit Reports of the institution during 2012-2014 and a financial and economic analysis was performed in order to establish some indicators of solvability, profitability and financial balance. Findings: It exists a lack of consistency in managing the profits obtained. We can also suggest that should be given a greater interest to the management of their own intangible assets, as brand management, for example. Practical implications: By making known to leaders and managers of this type of institutions that exists a link between participation in international championships and increase of their profitability may encourage them to better managing these cash inputs in order to decrease the dependence of Governmental financing. We also found that the management of their own intangible assets, as brand management, for example, could probably add more positive financial results.

A new approach for measuring corporate reputation

This study describes the concept of corporate reputation and reviews some of the major points that exist when it comes to measuring it. It thus suggests a new index for measurement and its advantages and disadvantages are pointed out. The consistency of the seven key variables for the collecting indicator is described by the results of a factor analysis and correlations. Finally, the indicator is put to test by gathering the perception of corporate reputation of 1500 individuals for 69 companies belonging to 15 different industrial sectors, in Peru. The results indicate that the proposed index variables are not necessarily of greatest interest to the study sample in which companies have a better performance. Also greater memorial companies aren't necessarily those that enjoy a greater corporate reputation. Managerial implications for the organizations in the process of managing and monitoring the dimensions involved of this key asset are also referenced.
