Teoría de la educación : educación y cultura en la sociedad de la información
2011
Se exponen las principales perspectivas en el estudio del comportamiento informacional: la perspectiva del usuario y la del sistema. En el primer caso, se asume una visión global del proceso de búsqueda de información y se desarrollan modelos teóricos y metodológicos para guiar la investigación en este campo. Se presentan como ejemplo la teoría del Sense-Making de Brenda Dervin y el modelo de Proceso de Búsqueda de Información de Carol Kuhlthau. En el segundo caso, se asume una perspectiva parcial del proceso de búsqueda de información, centrándose fundamentalmente en las transacciones entre usuario y el sistema o entre el usuario y la información. Se describen los estudios del uso de recur…
Progression of Diiminopyridines: From Single Application to Catalytic Versatility
2015
Diiminopyridyl metal complexes, first characterized several decades ago, found practical application in 1998 when they were used as precatalysts in coordinative ethylene polymerization. This discovery contributed to the so-called postmetallocene revolution and triggered the large-scale experimental and theoretical research aimed at understanding diversified diiminopyridine chemistry. The results of this quest, some of which were intriguing and difficult to anticipate, are discussed and summarized in the current Review.
FRP reinforcement for concrete structures: state-of-the-art review of application and design
2014
Fiber reinforced polymers (FRPs) are considered to be a promising alternative to steel reinforcement, especially in concrete structures subjected to an aggressive environment or to the effects of electromagnetic fields. Although attempts to develop effective reinforcement have been followed, the application of FRPs remains limited by the solution to simple structural problems that mainly appear due to the absence of design codes, significant variation in the material properties of FRP composites and limited knowledge gained by engineers as regards the application aspects of FRP composites and structural mechanics of concrete elements reinforced with FRPs. To fill the latter gap, the current…
A smartphone application of “Family Connections” to increase the use of skills and improve psychological symptoms in relatives of people with borderl…
2022
The literature reveals that borderline personality disorder (BPD) is an important public mental health problem that affects both the patients and their families. Moreover, studies indicate a high prevalence of psychological symptoms and burden in relatives of people with BPD. Therefore, it is necessary to develop useful and accessible interventions specifically addressed to the caregivers. Smartphone interventions with Ecological Momentary Assessment (EMA) and Ecological Momentary Interventions (EMI) offer several potential advantages in this regard. The aims of our study are to test the effectiveness of a combined intervention supported by a smartphone app versus the same intervention supp…
Antitumor Effect of Cabozantinib in Bone Metastatic Models of Renal Cell Carcinoma
2021
Background: The presence of bone metastases in renal cell carcinoma (RCC) negatively affects patients’ survival. Data from clinical trials has highlighted a significant benefit of cabozantinib in bone metastatic RCC patients. Here, we evaluated the antitumor effect of cabozantinib in coculture models of renal cell carcinoma (RCC) and osteoblasts (OBs) to investigate whether and how its antiproliferative activity is influenced by OBs. Methods: Bone/RCC models were generated, coculturing green fluorescent protein (GFP)-tagged Caki-1 and 786-O cells with human primary OBs in a “cell–cell contact” system. RCC proliferation and the OB molecular profile were evaluated after the cabozantinib treat…
Efectos positivos en la Educación Universitaria del uso de aplicaciones basadas en la Metodología Mobile-Learning
2020
El objetivo de este trabajo es analizar cómo el rendimiento académico del alumnado puede verse influenciado por el uso de diferentes aplicaciones basadas en la metodología Mobile - Learning , el expediente académico, y la asistencia a las aulas. En particular este estudio, se centra en la forma en la cual el uso de la plataforma tecnológica Kahoot! en las aulas universitarias como herramienta complementaria a las clases magistr ales puede afectar al rendimiento académico de la asignatura. La base de datos utilizada para contrastar las hipótesis planteadas ha sido creada utilizando los datos obtenidos de 39 alumnas/os de la asignatura Dirección de Operaciones, una asignatura oblig atoria de …
The genome sequence of Blochmannia floridanus: Comparative analysis of reduced genomes
2003
Bacterial symbioses are widespread among insects, probably being one of the key factors of their evolutionary success. We present the complete genome sequence of Blochmannia floridanus , the primary endosymbiont of carpenter ants. Although these ants feed on a complex diet, this symbiosis very likely has a nutritional basis: Blochmannia is able to supply nitrogen and sulfur compounds to the host while it takes advantage of the host metabolic machinery. Remarkably, these bacteria lack all known genes involved in replication initiation ( dna A, pri A, and rec A). The phylogenetic analysis of a set of conserved protein-coding genes shows that Bl. floridanus is phylogenetically related to Buch…
Firm growth and profitability : The role of age and size in shifts between growth–profitability configurations
2023
To investigate the routes toward profitable growth, this study partially replicates and extends the work of Davidsson et al. (2009) on firm growth–profitability dynamics with multi-industry data on over 66,000 Finnish firms. The results support prior findings on initial profitability being more important than initial growth for achieving high performance in both performance dimensions. Additional investigations on the role of firm age and size reveal further interesting dynamics: Very small young firms face fewer risks from growing at a low profitability level than other firms, and the benefits of firm size for future performance depend on the firm's current profitability. The results advan…
Selecting the special or choosing the common? A high-powered conceptual replication of Kim and Markus’ (1999) pen study
2022
Kim and Markus (1999) found that 74% of Americans selected a pen with an uncommon (vs. common) color, whereas only 24% of Asians made such a choice, highlighting a pronounced crosscultural difference in the extent to which people opt for originality or make majority-based choices. The present high-powered study (N = 729) conceptually replicates the results from Kim and Markus (1999; Study 3). However, our obtained effect size (r = .12) is significantly weaker than that of the original study (r = .52). Interestingly, given the globalization of mass media and the rapid economic progress of many Asian cultures during the last decades, a larger proportion of Chinese, but not American, participa…
La représentation sociale de l'hygiène chez les professionnels de santé : Intérêt du recueil par entretien et de l'analyse discursive des opérateurs …
2009
This study deals with professional representations. The goal is to show the representation of hygiene by health care workers: Nurses (N) and Health Care Aides (HCA). Method follows the BSC (Bases Cognitive Schemes) procedure, explicative interviews substitute to the evaluation task. An analysis of associative words points out that for HCA hygiene is associated with acts linked with corporal hygiene and with two synonymous: no trace, no germ Discussion underlines the interest of this method for professional representations studies and nosocomial infections strength.
