A Computationally Efficient Online/Offline Signature Scheme for Underwater Wireless Sensor Networks
2022
Underwater wireless sensor networks (UWSNs) have emerged as the most widely used wireless network infrastructure in many applications. Sensing nodes are frequently deployed in hostile aquatic environments in order to collect data on resources that are severely limited in terms of transmission time and bandwidth. Since underwater information is very sensitive and unique, the authentication of users is very important to access the data and information. UWSNs have unique communication and computation needs that are not met by the existing digital signature techniques. As a result, a lightweight signature scheme is required to meet the communication and computation requirements. In this researc…
A new forum for upconversion research: The UPCON conference
2019
International audience; The Conference and Spring School on Properties, Design and Applications of Upconversion Nanomaterials (UPCON) provides a new forum for all experts and newcomers in the field of upconversion research. On the occasion of the second UPCON 2018 in Valencia (Spain), we are pleased to present a collection of 12 reviews and research articles that reflect recent advances in upconversion materials, their unique luminescent properties and many applications spanning from nanoscale thermometry to biomedicine.
Iekšējās informācijas izmantošana un nelikumīga izpaušana finanšu instrumentu tirdzniecībā
2022
Bakalaura darba tēma ir iekšējās informācijas izmantošana un nelikumīga izpaušana finanšu instrumentu tirdzniecībā. Ņemot vērā kapitāla tirgu ietekmi uz pasaules ekonomiku un iespējamo kapitāla tirgu aktivizēšanos Latvijas Republikā, pieaug arī ar šo nozari saistīto riski. Tādēļ ir nepieciešams analizēt ļaunprātīgas tirgus manipulēšanas apkarošanas institūtu, kā arī aplūkot iespējamo personas atbildību par nelikumīgu iekšējās informācijas izpaušanu un izmantošanu. Darba mērķis ir izpētīt iekšējās informācijas ļaunprātīgas izmantošanas apkarošanas institūtu, analizējot Eiropas Savienības regulējuma attīstību un ietekmi uz Latvijas Republikas normatīvajiem aktiem, kā arī izpētot Amerikas Savi…

Resilience and the Aging Process: Assessment Tools and Needs
2015
Abstract Successful resilience is a variable often related to an optimal aging process and that might have a role on education. However, literature is rather limited when dealing with assessment instruments for the elderly in the Spanish language. The objective of this work is to examine the Brief Resilient Coping Scale (Sinclair &Wallston, 2004), a four item likert scale, in the Spanish elderly. This scale was administrated to a sample of 920 elderly Spanish participants, and the data set analysed in terms of exploratory and confirmatory factor analysis and internal consistency. The scale demonstrated good psychometric properties. Furthermore, the homogeneity indices were higher than in th…
Spanish Validation of the Flourishing Scale in the General Population
2017
Well-being research and its measurement have grown in the last two decades. The objective of this study was to adapt and validate the Flourishing Scale in a sample of Spanish adults. This was a cross-sectional study using a non-probabilistic sample of 999 Spanish general adult population participants. The psychometric properties of the scale were analysed from an exploratory and confirmatory perspective. Exploratory factor analysis showed a one-factor solution explaining 42.3% of the variance; an internal consistency of .846; temporal reliability correlation of .749; convergent validity with the Satisfaction with Life Scale of .521 and criterion validity with positive and negative affect (P…
Diseño y validación de un instrumento para evaluar la colegialidad docente
2016
El estudio trata de diseñar y validar un instrumento de evaluación de la colegialidad docente, como calidad de unión entre el profesorado de los centros docentes de educación primaria de España y México. El instrumento diseñado se basa en seis dimensiones: (1) valores éticos y profesionales compartidos; (2) cohesión y confianza en el grupo, actitudes de alianza, compañerismo; (3) compromiso con la tarea docente, actitud de mejora profesional continua; (4) toma de decisiones colegial sobre la tarea docente; (5) relaciones docentes colaborativas: autonomía y colectividad en la tarea docente, respeto y constructivismo en las relaciones interpersonales; (6) Clima dinámico y positivo del centro,…
International Assessment Surveys of Educational Achievement in Developing Countries : Why Education Economists Should Care
2015
International audience; This paper reviews the most known international assessment studies that are conducted in the context of poor countries and highlights the lack of empirical evidence on the degree to which the contents of the tests really match countries' curricula. To illustrate, the paper evaluates the sensitivity of an international testing instrument by comparing the responses of students in two consecutive grades on the same battery of tests. Using propensity score matching to control for student and teacher characteristics, the results show that the tests are not grade sensitive, which raises the question of the validity of many empirical works that are based on similar instrume…
Linguistic, Contextual, and Experiential Equivalence Issues in the Adaptation of a Performance-Based Assessment of Generic Skills in Higher Education
2022
This qualitative study investigated the various linguistic, contextual, and experiential equivalence issues embedded in a performance-based instrument aimed at assessing generic skills in higher education. A rigorous translation and adaptation process (American English to Finnish) was conducted on one instrument, namely Collegiate Learning Assessment (CLA+) International. The data were obtained from cognitive laboratories (n = 13), with think-alouds and follow-up interviews conducted among Finnish undergraduate students. Content logs were created, and the data were analyzed thematically. The findings revealed that linguistic and contextual equivalence issues were more prominent than experie…
