Las técnicas extendidas en el clarinete del repertorio español (1970-1990) : estudio analítico comparativo

Debido a mi formación como clarinetista, la redacción del Trabajo Fin de Grado me ofreció una buena oportunidad para investigar acerca de mi instrumento desde un punto de vista más teórico que práctico. El estudio en el ámbito de la música contemporánea me hizo plantearme la búsqueda del repertorio español específico para el clarinete, ya que tanto en los currículos de las enseñanzas de los conservatorios profesionales como del Conservatorio Superior de Castilla y León1 se trabajan obras pertenecientes a las diferentes épocas en que aparece el clarinete, desde el clasicismo hasta la música actual, pero se presta poca atención al repertorio nacional contemporáneo. Los planes de estudio presentan amplios listados de composiciones, con el fin de abarcar los diversos estilos, pero se ven obligados a realizar un examen selectivo de las épocas y de los compositores más representativos. Además de la escasa incidencia de los conservatorios sobre el repertorio contemporáneo, las nuevas técnicas y las nuevas grafías, bibliográficamente tampoco existen demasiadas referencias editadas sobre este tema.Departamento de Didáctica de la Expresión Musical, Plástica y CorporalGrado en Historia y Ciencias de la Músic

Sexuality and contraceptive knowledge in university students: instrument development and psychometric analysis using item response theory

Background As a consequence of biological, psychological and social changes during puberty, youth is a period characterized by impulsiveness and risk-taking. Members of this population often feel invulnerable and have a strong motivation to explore their identity. A good level of knowledge is necessary to allow young people to experience their sexuality in a healthy way, without associated risks. In our environment there is currently no valid Spanish-language tool to measure the level of knowledge about sexuality and contraception. This study sought to develop and test the psychometric properties of a new sexuality and contraception knowledge instrument. Methods This is a cross-sectional study to validate the sexuality and contraception knowledge instrument. The validation process followed four phases: (1) development of the instrument, (2) content validation by an expert panel, (3) pilot test and (4) psychometric analysis of the instrument using item response theory according to the Rasch model. The validation process took place from September 2017 to February 2018. Results The sample included 387 students enrolled at the Nursing and Law degrees from the University of Jaen. The final instrument was made up of 15 items. All of the items presented good adaptation values with respect to the model. The scale showed good fit and reliability: 0.99 for items and 0.74 for people. The temporal stability of the scale was calculated using test–retest, obtaining a value of 0.81 (CI 0.692–0.888). The construct validity showed the one-dimensionality of the construct, while the discriminant validity obtained good results, so the scale appears to be able to differentiate between participants with low or high levels of knowledge. Conclusion The results suggest the Sexuality and Contraception Knowledge Instrument is psychometrically valid and reliable for measuring the knowledge level concerning sexuality and contraceptive methods in young university students

Educational program on sexuality and contraceptive methods in nursing degree students

Background: Previous educational programs about sexuality and contraceptive methods are delivered through vertical teaching methodology and use an increase in knowledge level as an indicator of effectiveness; however, attitudes towards contraceptive use are not addressed. Objectives: This study aimed to evaluate the effect of a peer-educational intervention to improve knowledge level and attitudes regarding contraceptive methods in university students. Design: A pre-post quasi-experimental study. Settings: Young university students from a Spanish university. Participants: 131 students in their second year of the Nursing degree program. Methods: An intervention consisting of two 3-hour sessions was conducted. The first session introduced the main aspects of contraceptive methods and was conducted by the teacher. The second session began with student presentations about contraceptive methods, followed by clinical simulations of a family planning service that the students had to implement and solve. Results: There was a 71.43% improvement in the knowledge level scale score and a 2.17% improvement in the attitudes towards the use of contraceptive methods; both were statistically significant (p < 0.001). For 11 of the 15 items in the knowledge scale, a significantly higher proportion of success was found after the intervention. Conclusion: Peer-educational intervention was effective in improving knowledge level and attitudes about contraceptive methods

Aprendizaje relacional de la matemática en el bachillerato

El perfeccionamiento del sistema educacional, particularmente de la asignatura Matemática, debe garantizar que el nivel de conocimientos, la formación de hábitos y habilidades en los estudiantes se correspondan con las exigencias de los objetivos declarados para cada nivel educativo. El trabajo aborda el perfeccionamiento de la formación de profesores de Matemática en las Universidades de Ciencias Pedagógicas para el nivel preuniversitario a través de las relaciones entre los conocimientos matemáticos para contribuir a resolver las limitaciones que en el aprendizaje presentan los estudiantes. El aporte fundamental radica en el modelo didáctico para el aprendizaje de la Matemática a través de un proceso que revela las relaciones lógicas de significado entre los conceptos, proposiciones y procedimientos, que transitan por los niveles de los conocimientos básicos, generales y específicos y propicia la transferencia relacional, sobre la base de los nexos entre lo conocido y lo nuevo por conocer, así como la búsqueda activa de los conocimientos

Contact lenses that transform gold into nanoparticles for prophylaxis of light-related events and photothermal therapy

This work describes for first time how anisotropic gold nanoparticles (AuNPs) can be spontaneously formed inside preformed contact lenses (CLs) avoiding the use of additional reductant agents (reagent-free) through a precise tunning of the monomeric composition, the saline concentration, and the application of steam heat sterilization. Protocols to generate AuNPs in solution using inorganic or small organic reductants are widely available. Differently, gold precursors interactions with polymer networks have been overlooked and, thus, the interest of chemically cross-linked hydrogels as organic reductants is still to be elucidated. In the ocular field, incorporation of AuNPs to CLs may expand their applications in prophylaxis, therapy and diagnosis. To carry out the work, a variety of hydrogels and commercially available CLs were incubated with gold salt solution without any other chemical reagent. AuNPs formation was monitored by changes in localized surface plasmon resonance (LSPR) bands and quantifying the gold sorbed. Only silicone hydrogels induced AuNPs formation at room temperature in few days; methacrylic acid red-shifted the LSPR band (550–600 nm), while monomers bearing F hindered the reduction. Storage of hydrogels in the gold precursor solution allowed a gradual formation of anisotropic AuNPs, which could be stopped at any time by washing the hydrogel with water. The developed CLs behave as efficient filters against highly penetrant light and also exhibit photoresponsiveness as demonstrated as rapid (10 s), focused mild hyperthermia when irradiated with green, red and NIR lasersThe work was supported by MCIN [PID 2020-113881RB-I00/AEI/10.13039/501100011033], Spain, FEDER and Xunta de Galicia [ED431C 2020/17]S

Imágenes reversibles en la poesía andalusí y en la de Juan Ramón Jiménez

En otro artículo anterior, se vieron los vínculos que el estilo de Juan Ramón Jiménez presenta respecto de los autores árabes de "al-Andalus", en relación a la correspondencia conceptual de los términos "mujer = jardín = la poesía". En este artículo, se han analizado los recursos que permiten dar características de la naturaleza terrenal a los cuerpos celestes, incluso en los casos en los que cambia de dirección antropológica. Estos casos son llamados por Dámaso Alonso imágenes reversibles.In another previous article we already worked on the linkanges that the system of Juan Ramón Jiménez shows with the Arabian authors from “al-Andalus”, concerning the three terms correspondence "woman=garden=poetry". In this article, we have analyzed the resources that allow us to grant characteristics of Earthly Nature to Heavenly bodies, even in cases in which the anthropologic direction changes. These cases are called by Damaso Alonso reverting images.notPeerReviewe

What do consumers care about when purchasing experiential packaging?

Purpose: The importance of packaging attributes for purchase decisions has generated interest in the research and food industry. As a matter of fact, innovation in packaging is constantly searching for new solutions that generate customer experience. The aim of this study is to analyse the effect of packaging attributes (protection, convenience, portability and storage, information, sustainability, branding and engagement) on consumer purchase intention of experiential packaging especially designed to provide an extraordinary sensory or interactive communicational experience and the influence of potential moderators. Design/methodology/approach: The authors used a quantitative methodology based on the partial least squares (PLS) technique to estimate the structural model proposed. A purposely developed questionnaire was administered to a non-probabilistic sample of 1,489 European consumers. The questionnaire included questions related to consumers' perception of packaging attributes and purchase intention of different experiential packages. Findings: The results indicate that packaging attributes are related to consumer purchase intention of experiential packaging. Engagement attributes show the strongest positive influence followed by branding and economy. However, attributes such as sustainability showed a negative effect on the purchase intention of these packages. The authors’ results also show the influence of gender, family structure and residential background as moderators of the relationships. Originality/value: Customers' decision-making processes are strongly influenced by product packaging. However, little is known about how new technologies and design in packaging influence consumers' responses. This research provides evidence of the influence of packaging attributes on consumer purchase intention for experiential packaging, a proliferating area of research

Effectiveness of scenario‑based learning and augmented reality for nursing students’ attitudes and awareness toward climate change and sustainability

Background: Mainstreaming sustainable healthcare into the curricula of health professions is a key action to raise awareness and change attitudes. Therefore, the present study aimed to assess the contribution of scenario-based learning and augmented reality to the environmental awareness and attitudes toward climate change and sustainability among undergraduate nursing students. Methods: This study was designed as a time-series analysis. Undergraduate nursing students in their 3 years were introduced to sustainability and climate change in the context of healthcare through scenario-based learning sessions. Questionnaires were used to collect data on participants’ attitudes towards sustainability and climate change, the usefulness of the educational sessions and the extent to which students changed their clinical practice. A data summary, related sample Friedman and Wilcoxon signed-rank tests were used to test for differences in survey scores. Results: Attitudes and environmental awareness toward climate change and sustainability increased significantly as students received the learning sessions over the 3 years. After their first clinical training period, students already showed a high awareness of unsustainable practices in their working environment; however, they still struggled to apply sustainability and address unsustainable practices in healthcare settings. Most students felt that the scenarios helped them to make links between climate change, resources, and health. Conclusions: The scenario-based learning and augmented reality increase environmental awareness and attitudes toward climate change and sustainability among nursing students. Students are very aware of unsustainable practices in their work environment, but more work needs to be done on the application of sustainability principles to nursing practice

Effectiveness of the e-NurSus Children Intervention in the Training of Nursing Students.

The paediatric population is the most vulnerable to exposure to environmental risk factors. Institutions of higher education have to equip nursing students with the attitudes, knowledge, and skills to respond to this using blended learning. The aim of this study was to evaluate the effect of e-NurSus Children intervention on student nurses’ attitudes, knowledge, and skills. A quasi-experimental study of time series was designed using pre and post educational intervention evaluation in 2018. The participants were nursing students (N = 267) from Spain (n = 110) and the United Kingdom (n = 157). Three instruments were used: the Sustainability Attitudes in Nursing Survey, the Children’s Environmental Health Knowledge Questionnaire, and the Children’s Environmental Health Skills Questionnaire. The attitudes (15.81%), knowledge (39.02%), and skills (29.98%) of nursing students improved following the e-NurSus Children intervention. It is necessary to include topics on children’s environmental health in nurse education as students are aware of this issue but do not have the knowledge or skills required to manage problems or illness caused by the environment. The e-NurSus Children intervention is an effective tool to address this educational gap

Palladium-catalysed amination of 2-acyl-1-alkyl-5-bromopyrroles

The first intermolecular C–N bond-forming reactions between substituted 2-bromopyrroles and primary and cyclic secondary amines were performed using Pd2(dba)3 as catalyst with BINAP as the ligand. The aminations proceeded in the presence of NaOtBu at 80–100 °C in 31–93% yields.Financial support from the Comisión Interministerial de Ciencia y Tecnologı́a (CICYT, project BQU2001-1508) is gratefully acknowledged
