La construcció del coneixement gramatical en aprenents d'educació primària i secundària: algunes aproximacions a l'aprenentatge del verb
2017
El verb és una de les categories que una gramàtica escolar ha d’abordar necessàriament, tant pel que fa al coneixement de la noció i de la seva relació amb altres categories, com per la funció fonamental que pren en l’escriptura. En aquest article presentem tres recerques que descriuen el procés d’aprenentatge que els alumnes de primària i de secundària segueixen a l’hora d’aprendre continguts vinculats amb el verb: el temps del present, el mode verbal i la complementació verbal. Aquests treballs mostren quines estratègies desenvolupen els aprenents i quins obstacles han d’afrontar per desenvolupar un raonament gramatical. Dels estudis es desprèn que determinades intervencions didàctiques (…
Determinants of Vertical Coordination in Buyer-Seller Relations: Exploratory Findings from a Developing Economy
2011
This study aims at understanding determinants of vertical coordination for firms in developing economies by conducting exploratory study in Tanzania. The study is centred on business - to business buyer -seller relations. Primary data were collected from buying side of the relationship. The main supplier of each firm was identified and used for answering the questionnaire.Findings suggest contractual flexibility to have higher significant positive effect in determining vertical coordination. The interaction effect between buyer asset specificity and contractual flexibility was also significant, while asset specificity by itself was not found to be significant. These prelimenary findings sug…
Muscular MEMS—the engineering of liquid crystal elastomer actuators
2016
A new class of soft-matter actuator, the liquid crystal elastomer (LCE), shows promise for application in a wide variety of mechanical microsystems. Frequently referred to as an 'artificial muscle', this family of materials exhibits large actuation stroke and generates considerable force, in a compact form which may easily be combined with the structures and devices commonly used in microsystems and MEMS. We show here how standard microfabrication techniques may be used to integrate LCEs into mechanical microsystems and present an in-depth analysis of their mechanical and actuation properties. Using an example from micro-optics and optical MEMS, we demonstrate that their performance and fle…

The Effects of Acceptance and Commitment Therapy (ACT) Intervention on Inflammation and Stress Biomarkers : a Randomized Controlled Trial
2020
Abstract Background Psychological processes can be manifested in physiological health. We investigated whether acceptance and commitment therapy (ACT), targeted on psychological flexibility (PF), influences inflammation and stress biomarkers among working-age adults with psychological distress and overweight/obesity. Method Participants were randomized into three parallel groups: (1) ACT-based face-to-face (n = 65; six group sessions led by a psychologist), (2) ACT-based mobile (n = 73; one group session and mobile app), and (3) control (n = 66; only the measurements). Systemic inflammation and stress markers were analyzed at baseline, at 10 weeks after the baseline (post-intervention), and…
Introducing mindfulness and compassion‐based interventions to improve verbal creativity in students of clinical and health psychology
2021
OBJECTIVES In the field of psychotherapy, verbal creativity has been suggested as an important aspect in psychotherapists' training. In the present study, the effects of a mindfulness and compassion-based intervention (MCBI) on verbal creativity are analysed in students of clinical and health psychology (N = 90). DESIGN Students were randomly assigned to an experimental group (n = 37), in which an MCBI was applied, and a waiting list group (n = 26) with no intervention. We also assessed a non-randomized active control group (n = 27), in which students received training in basic psychotherapy skills. METHODS Verbal creativity (fluency, flexibility, and originality) was evaluated in a pre-, p…
Using the Modelling and Simulation Techniques to Improve the Management of SMEs Belonging to Regional Clusters
2015
Abstract The efficiency of exploiting the software takes on new dimensions under the conditions of integrated exploitation at the level of process and structural organization of SMEs found within the regional strategic alliances. The modeling and simulation of the leadership and regulation processes of the supply, sales and production flows imply a complex display of forces between the different partners of the logistic chain which can be supported by the existence of some data bases developed based on information partnership whose purpose is to counterattack the communication barriers and to ensure a flow and flexibility of the entire logistic flow. The modeling and simulation of the non-i…
Mechanical Properties of Pore-Spanning Lipid Bilayers Probed by Atomic Force Microscopy
2006
AbstractWe measure the elastic response of a free-standing lipid membrane to a local indentation by using an atomic force microscope. Starting point is a planar gold-coated alumina substrate with a chemisorbed 3-mercaptopropionic acid monolayer displaying circular pores of very well defined and tunable size, over which bilayers composed of N,N,-dimethyl-N,N,-dioctadecylammonium bromide or 1,2-dioleoyl-3-trimethylammonium-propane chloride were spread. Centrally indenting these “nanodrums” with an atomic force microscope tip yields force-indentation curves, which we quantitatively analyze by solving the corresponding shape equations of continuum curvature elasticity. Since the measured respon…
Revisiting the cysteine-rich proteins encoded in the 3’-proximal open reading frame of the positive-sense single-stranded RNA of some monopartite fil…
2020
A reexamination of proteins with conserved cysteines and basic amino acids encoded by the 3 '-proximal gene of the positive-sense single-stranded RNA of some monopartite filamentous plant viruses has been carried out. The cysteines are involved in a putative Zn-finger domain, which, together with the basic amino acids, form part of the nuclear or nucleolar localization signals. An in-depth study of one of these proteins, p15 from grapevine B virus (GVB), has shown: (i) a three-dimensional structure with four alpha-helices predicted by two independent in silico approaches, (ii) the nucleolus as the main accumulation site by applying confocal laser microscopy to a fusion between p15 and the g…
Experimental Tests and FEM Model for SFRC Beams under Flexural and Shear Loads
2008
The complete load-vs-displacement curves obtained by four-point-bending tests on Steel Fiber Reinforced Concrete (SFRC) beams are predicted by using a nonlinear finite element code based on the Modified Compression Field Theory (MCFT) and the Disturbed Stress Field Model (DSFM) suitably adapted for SFRC elements. The effect of fibers on the shear-flexure response is taken into account, mainly incorporating tensile stress-strain analytical relationship for SFRC. The numerical results show the effectiveness of the model for prediction of the behavior of the tested specimens reinforced with light amount of stirrups or with fibers only. © 2008 American Institute of Physics.
