Modelling pavement surface characteristics for noise prediction through Bailey-related indicators
2021
The aggregate gradation of bituminous mixtures (hot mix asphalts, HMA) is one of the major factors affecting their surface texture. In turn, this latter is a crucial factor and influences drivers and bystanders’ safety, comfort, and health. Despite this, the design of texture levels still lacks sound bases and dedicated algorithms and this negatively affects the acoustic design of bituminous mixtures. Consequently, the objectives of this study were confined into the derivation of relationships to be used in mix design to predict texture levels. Experimental data were analyzed, in the pursuit of setting up appropriate models and algorithms. Analyses involved the consideration of Bailey-relat…
The role of IPR arrangements in the crowdsourcing for innovation contest: an empirical investigation of the Innocentive challenges
2017
In this study, we identify three different Intellectual Property Right arrangements- strong IPR (acquiring an IP), weak IPR (licensing agreement) and flexible IPR. Integrating Property Rights Theory and the open innovation literature, we propose that specific challenge attributes affect the seekers organizations’ choice between alternative IPR arrangements and how this choice, in turn, affects the self-selection of external solvers into solving the problem. We collected multi-source, interview data with open innovation directors and a unique data set of 819 closed and awarded challenges broadcasted on InnoCentive platform from 2010 to 2016. Our findings contribute to the emerging literature…
Relación entre la percepción de validez de una rúbrica, el rendimiento académico y la autorregulación de estudiantes de ciencias del deporte
2021
[EN] The use of rubrics can be an especially useful tool to align the teaching, learning and evaluation processes of oral presentation. Its validity is essential to assess academic performance and may be influenced by student self-regulation. The objective of the study was to determine the perception of validity and utility of a rubric for students of the Physical Education and Sports Sciences degree, as well as to identify the relationship between this perception, their academic performance and their self-regulation. 123 students participated in the study. The teacher of the subject provided the rubric to evaluate oral presentations. After oral presentations, students answered two question…
The influence of innovation stimulus, facilitating factors and support mechanisms on innovation performance in Brazilian small textile firms
2020
The ability of the organisation to develop new products is crucial in rapidly changing business environments, and thus, customer demographics, consumers' expectations and buying behaviour play an important role. Hence, exploring the antecedents of innovation performance becomes more important. This study analyses the relationships among innovation stimulus, facilitating factors and support mechanisms for innovative performance in the textile industry of Santa Catarina, Brazil. The sample included 128 respondents, who were all employees of five small and medium-sized textile firms; data were analysed using structural equation modelling. We found that innovation stimulus, facilitating factors…
Knowledge Flows and Innovative Performance. Evidence from Italian Firms

Ion-exchange high-performance liquid chromatography of nucleotides and polypeptides on new types of ion-exchange sorbents, based on polystyrene-coate…
1991
A novel type of ion exchanger was prepared by multipoint covalent binding of polystyrene chains onto the surface of porous silica followed by polymer-analogous modification of the bonded layer. Both anion and cation exchangers were synthesized and examined in the separation of nucleotides and proteins. Rapid and efficient separation of basic polypeptides on strong anion exchangers and that of acidic polypeptides on strong cation exchangers could be achieved. For the separation of complete mixtures of polypeptides the application of zwitter-ionic ion exchangers can be recommended.

De la atención de los problemas de la audición y lenguaje a la logopedia como disciplina
2015
Las dificultades del lenguaje han estado presentes en el ser humano desde la antigüedad. La sensibilización social e institucional hacia este tipo de trastornos ha mejorado lentamente hasta nuestros días. Ya en la Edad Moderna (siglos XVI al XVIII) se informa de educación de sujetos con problemas de lenguaje. Destaca el trabajo de Pedro Ponce de León como precursor del tratamiento estas dificultades. De forma progresiva, se tomó conciencia de la importancia del tratamiento de las dificultades del lenguaje. En los siglos XIX y XX se produce la institucionalización de la atención a personas con trastornos del lenguaje. La Orientación Educativa atiende tradicionalmente esta problemática. Poste…
Motivation and academic performance among first-graders : A person-oriented approach
2016
The present study applies a person-oriented approach to examine the motivational patterns children show on the basis of their reading- and math-related intrinsic value and self-concept of ability and how these patterns are related to their reading and math performance during the first grade of elementary school. The participants were 156 first grade children. The children were examined at the beginning and at the end of their first grade of elementary school. Five groups of children showing differing motivational patterns were identified using the ISOA procedure: Positive, Negative, Math-motivated, Reading-motivated, and Low interest but high belief. Children's motivational patterns were as…
THE INFLUENCE OF TRAINING ON THE LEVEL OF TEST PERFORMANCE AND THE FACTOR STRUCTURE OF INTELLIGENCE TESTS
1965
An attempt was made to study whether it is possible by specific training on one test to produce changes in the level of performance on similar tests and in the factor structure of a set of intelligence tests. Considerable improvement occurred in the level of performance on the test on which training was given, but no significant transfer effects to the performance on other tests were found. Slight differentiation was observed in the factor structure.
