Pair interactions in online assessments of collaborative problem solving: case-based portraits

2018

This exploratory case study focuses on how pairs of students can build a shared understanding and acquire collaborative problem-solving (CPS) practices during an online assessment of CPS skills, which is seen in the context of the CPS construct, in a symmetrical and asymmetrical task type. Even though CPS is widely recognised as a core twenty-first-century competency, its nature is not yet well understood. Also, until recently, most of studies have focused on the individual’s solution to a problem or on the skills individuals bring into a problem-solving space. This study extends from an individual- to group-level focus in CPS, emphasising the role and quality of the social aspects in CPS p…

Designing and Implementing a CSCL-based Course on the Data Security of a Wireless Learning Environment

2012

This article reports on a design-based research (DBR) process for designing and implementing a computer-supported collaborative learning (CSCL) course on the data security of wireless learning environments. The study focuses on examining how university students practice data security when learning on a wireless campus, how data security aspects appear in this study and how students perceive the role of data security in CSCL. The research subjects included six pilot students and eight students enrolled in the course. To promote the reliability of the findings, various kinds of data were used. The data was analysed following the grounded theory approach. The results suggest that data security…

Best practices for International eSourcing of Software Products and Services

2008

This paper analyzes how the information and communications technology-supported international eSourcing of software products and services (IeS) can be effectively executed. The extant literature falls short of providing a systematic and detailed enough set of best practices to guide IeS. This paper presents best practices for IeS to facilitate further research, and to help managers and other stakeholders to understand, execute, and proactively improve and manage international eSourcing. The practices emphasize the need to establish and enact rigorous, mature, and quantitatively managed eSourcing life- cycles in order to transcend temporal, geographical, social, technical, and other boundari…

Màdel, una modalidad de pelota a mano para todos los públicos

2021

El màdel és una nueva modalidad deportiva nacida en 2013 en València con el objetivo de aprovechar las instalaciones de un deporte en auge como el pádel para la práctica de la pelota a mano (Pilota Valenciana). Desde su aparición, cada vez son más los practicantes y los clubes que se han interesado por esta práctica. Una modalidad con un gran componente lúdico y recreativo, muy completa físicamente. Gracias a las características de las instalaciones, el material necesario para su práctica y su reglamento de fácil comprensión y aprendizaje se erige en un activo muy interesante para el fomento de la iniciación a la práctica deportiva para todos los públicos. En la siguiente comunicación, desp…

Transport mechanism of peptides through supported liquid membranes

2007

The transport of selected dipeptides through supported liquid membranes impregnated with di(2-ethylhexyl) phosphoric acid in n-dihexyletherhas been investigated. The fluxes depend on the side chain of amino acids, presence in the peptide structure. The highest fluxes were obtainedfor the peptides extracted with the highest efficiency. It has been found that the hydrophobicity of investigated peptides, was not the major factor, influences their SLM permeation. In the conditions studied, it has been observed that the transport of peptide–carrier complex was depending on the acidic–basic properties of the analyte. The linearly least-square fittings of log { K 1 +[H + ]D } and log[(HR) 2 ] enable to…

Perspectivas actuales de la filosofía y la pedagogía del deporte

2016

La filosofía del deporte, al igual que la pedagogía, la historia y otros estudios humanísticos alrededor del fenómeno deportivo, ha permanecido tradicionalmente en un segundo plano en facultades e instituciones educativas, incluso en aquellas cuyo fin es, precisamente, comprender adecuadamente cómo y por qué jugamos del modo que lo hacemos y con qué finalidades (Kretchmar, 2005). En una reciente editorial de la revista Sport, Ethics and Philosophy, Michael McNamee (2015) hace un repaso de la actualidad, exponiendo cómo a pesar de que la disciplina no para de crecer y ganar protagonismo, sobre todo en el ámbito editorial, no acaba de hacerse el hueco pertinente en la academia. Por otro lado,…

Extraction of peptides from body fluids using supported liquid membranes

2008

Sample pre-treatment is a very important step in many analytical procedures, especially when the analyte is presented in low concentration in complex sample matrices. In this paper, potential using of the supported liquid membrane (SLM) technique as a sample preparation step in order to isolate, pre-concentrate and separate small peptides and phosphono dipeptides from aqueous solutions and body fluids is discussed. An influence of various parameters including carrier type, donor and acceptor phase compositions, presence of salts and proteins in analysed samples on extraction efficiency and selectivity is presented. Additionally, comparison of SLM extraction efficiency from aqueous samples a…

Conséquences d'un régime diabétogène enrichi en fructose sur la muqueuse olfactive : aspects anatomiques, fonctionnels et comportementaux

2015

The influence of metabolic status on olfactory processes has been thoroughly investigated over the last few years. Both nutritional status and hormones implicated in food metabolism can effectively modulate the olfactory system from the single neuron to the behavior. Thus, it seems likely that metabolic disorders such as type 2 diabetes (T2D) can induce olfactory dysfunctions. In fact T2D patients display poor olfactory performances however the effects of diabetes in itself (as well as underlying mechanisms) are still unknown. In this study, we investigated the modulation of olfaction in young adult male mice caused by a high-fructose diet (HFruD) inducing T2D in rodents. Animals displayed …
