The article presents a Parser class in Java to evaluate algebraic expressions using fundamental algorithms for the construction of compilers, passing from the conversion of expressions from infix to postfix, the evaluation of postfix expressions, the evaluation for precedence of operators, parser algorithms of precedence and construction algorithm of precedence functions. The goal of the article is to write a lexical analyser in a conventional language of systems programming, using the possibilities of input and output of Java language in order to read expressions to evaluate from the input, to process them and to send the results to the output.

El mero nombre del autor madrileño Juan Mayorga (figura sobresaliente de la dramaturgia contemporánea en español, y cuya profunda rigurosidad y densidad de motivos temáticos y constructivos singulariza y acredita su trabajo) ya debería poner siempre en guardia a sus lectoespectadores. No obstante, a finales de febrero de 2022 el autor sorprendió a sus seguidores con un texto complejo y profundamente filosófico: El Golem. Publicado por Ediciones La Uña Rota (2022), este libro era esperado porque Mayorga lo escribió durante la pandemia y, sobre todo, porque en él acoge un drama cuyo estreno, ligeramente anterior a la edición, creó la necesidad de ir o volver sobre su texto con el detenimiento que nos permite la página escrita; leer para descifrar una obra basada, precisamente, en el potencial de la palabra. Puesta en escena y libro de El Golem, por tanto, se miran y abrazan de...

El presente trabajo proporciona una panorámica sobre el actual debate de las técnicas de autoprovisión administrativa en España. El concepto de autoprovisión administrativa se utiliza para explicar las distintas opciones a disposición de los gestores públicos para la satisfacción de las necesidades administrativas de bienes y servicios dentro del propio sector público. Se discute también el panorama normativo de las decisiones administrativas de hacer o comprar al mercado, tal y como se configuran por la Ley 9/2017, de contratos del sector público, así como el surgimiento de mercados públicos al margen de los mercados empresariales de compra pública. Finalmente, todo ello se contextualiza en el debate transaccional en curso sobre la necesidad de mejorar la capacidad prestacional del sector público como herramienta de fortalecimiento del Estado de Bienestar.

This paper draws up an overview on the current status of in-house providing techniques in Spain. The concept of administrative self-supply is provided in order to cover and explain the most common modes of fulfilling the needs of services, goods and utilities whitin the public sector. We discuss the “make or buy decisions”, according to the new public procurement Act (9/2017), and the rise of public markets apart from business markets. Finally, we put this subject under the light of the transnational debate about the need of improving performance of public sector as a tool for Werlfare State empowerment.

Studying the actions of several institutions, as well as the popular belief according to which Galician people and Portuguese people have enough common ground as to fully understand each other, this article considers the reality of the matter in the context of international negotiation. We will study the use of the Galician language in international business, and then refute—or not—the hypothesis which indicates that the use of Galician can be the first step in a mutual understanding, but that it is necessary to be more deeply immersed in the language before facing an international negotiation—immersed in a way that also includes cultural knowledge.

Las escuelas con orientación inclusiva son consideradas como un medio eficaz de combate a actitudes discriminatorias. En el caso de los alumnos superdotados, se ha observado un interés por la realización de estudios involucrando a aquellos que presentan, simultáneamente, las habilidades superiores y dificultades conductuales, emocionales y de aprendizaje, fenómeno denominado doble excepcionalidad. El objetivo de este estudio de caso fue analizar la inclusión educativa de un alumno superdotado con trastorno de Asperger desde la perspectiva de gestores, profesores, madre y del alumno. La inclusión del participante fue considerada un proceso de naturaleza compleja y multidimensional por depender de la participación de toda la comunidad escolar y de la familia. Se verificó que la atención educativa especializada favoreció su inclusión educativa.

The purpose of this study was to examine the scientific production of empirical articles regarding twice exceptionality – giftedness/ADHD – through a systematic review. The search was carried out in the Portal de Periódicos Capes, SciELO, and PePSIC databases, considering the publications between 2011 and 2021. The terms giftedness, high abilities, ADHD, twice exceptionality, and their counterparts in Portuguese were used as descriptors. We selected 27 articles based on pre-established inclusion criteria. Six categories of studies were identified: socio-emotional factors, interpersonal relationships, identification, inattention and hyperactivity, intelligence quotient, and educational support practices. The conclusion was that by having their individual needs met and school community support, gifted students with ADHD can academically succeed, have a positive self-concept and good i...

Schools with an inclusive perspective are considered an efficient tool to fight the discriminatory attitudes. In the case of gifted students, there has been an interest in carrying out studies involving those who present, simultaneously to the higher abilities, behavioral, emotional and learning difficulties, a phenomenon named dual exceptionality. The purpose of this case study was to analyze the educational inclusion of a gifted student with Asperger’s disorder from the perspective of managers, teachers, mother and student himself. The educational inclusion of the participant was considered a complex and multidimensional process because it depends on the participation of the whole school community and family. It was verified that the specialized educational service favored the inclusion of the dual exceptional student.

Hub and spoke infringements involve illegal agreements between direct competitors (“spokes”) facilitated by a common supplier or customer (“hub”). These agreements combine vertical behaviors that may be seen as horizontal collusion by competition authorities. They are typically categorized as by-object infringements and carry significant penalties. Various actions, such as price indication and monitoring, are necessary to connect the vertical and horizontal aspects of the infringement. These practices pose challenges for competition law, such as reconciling them with legal concepts and determining the burden of proof. The authors aim to address these questions and evaluate hub and spoke infringement based on applicable rules, past decisions, and relevant literature.

Magnetic fields (MF) are increasingly being applied in food processing to preserve food quality. They can be static (SMF), oscillating (OMF) or pulsed (PMF) depending on the type of equipment. The food characteristics can be influenced by several configurations of the applied magnetic field as its flux density, frequency, polarity and exposure time. Several mechanisms have been proposed to explain the eects of magnetic fields on foods. Some of them propose interactions at the subatomic particle level that show quantum behavior, such as the radical pair and cyclotron resonance mechanisms. Other proposals are at the level of DNA, compounds, subcellular organelles and cells. The interactions between food and magnetic fields are addressed in a general way in this work, highlighting the applications and action models involved and their eects on the physicochemical, enzymatic and microbiologic...
