ROMANIAN SMES VERSUS THE GLOBAL FINANCIAL CRISIS-IMPEDIMENTS AND OPPORTUNITIES
2012
This paper studies the way small and medium sized enterprises have reacted towards the global financial crisis. It also attempts to study the impact this crisis had on both the activity of these enterprises and on the business mentality in Romania. The article studies the reasons which determined the SMEs’ vulnerability during the crisis; these belong to a wide range, spreading from the tightening of the financing options or of the activity, up to the management’s nature. The impact of the economic crisis is studied starting with the statistics in the specialty literature, which highlight the SMEs’ situation starting with 2008. Having as support these numbers, the paper analyzes the effects…
Heterogeneity in Disordered Gambling: Decision-Making and Impulsivity in Gamblers Grouped by Preferred Form
2019
Background: Previous research has indicated that disordered gamblers display deficits in impulsivity and risky decision-making, compared to healthy control groups. However, disordered gamblers are not a homogenous group, and differences in performance on neurocognitive tasks may be related to the form of gambling in which an individual chooses to engage. The present study used neurocognitive tasks and questionnaire measures to ascertain group differences in gamblers grouped by preferred form of gambling. Method: Treatment-seeking pathological gamblers from the National Problem Gambling Clinic, London (n = 101), completed a neurocognitive assessment comprising the Cambridge gamble task (CGT)…
Dual Information Systems: Supporting Organizational Working and Learning by Making Organizational Memory Transparent
1999
The conceptual design of most computer-based information systems reflects a dualism of technology. During the development phase, part of the work-domain-related knowledge is formalized and encoded in the software, making it difficult for users to reflect on and use this knowledge. This design--use dualism contributes to the deterioration of the interpretive flexibility of information systems. In this article, we outline an information systems architecture called Dual Information Systems (DIS) that incorporates the concepts of an organizational memory information system (OMIS) in a broader framework. DIS help bridge the design--use dualism by providing organizations with a set of services th…
Behavioral and psychological flexibility in eating regulation among overweight adults
2016
Weight-loss programs are often based on self-control techniques and they commonly fail in long-term weight management. Identifying psychological processes that explain eating behaviors can help to develop more effective interventions for long-term weight management. This research examined how behavioral and psychological flexibility are related to eating regulation and weight management in overweight adults. The first goal was to study the effects of flexible vs. rigid restraint of eating on weight-loss maintenance and well-being. The second goal was to examine whether psychological flexibility and mindfulness, independently and together, explain intuitive eating regulation. The third goal …
Relaciones entre neurocognición, procesamiento emocional y funcionamiento social en la esquizofrenia
2017
Resumen: En la esquizofrenia se presentan una serie de déficits cognitivos que han hecho que la investigación y la práctica profesional actual se centren en el estudio de la neurocognición y la cognición social. Estos déficits tienen importantes implicaciones en el funcionamiento social. El objetivo del presente trabajo es analizar la relaciones entre neurocognición, cognición social, evaluada con tareas de reconocimiento de la emoción, y funcionamiento social. Sesenta personas con diagnóstico de esquizofrenia han formado la muestra y las áreas evaluadas han sido: funcionamiento ejecutivo y flexibilidad cognitiva, atención y vigilancia, memoria, velocidad de procesamiento, identificación y …
Sagittal Plane Hip, Knee, and Ankle Biomechanics and the Risk of Anterior Cruciate Ligament Injury: A Prospective Study
2018
Background: Stiff landings with less knee flexion and high vertical ground-reaction forces have been shown to be associated with an increased risk of anterior cruciate ligament (ACL) injury. The literature on the association between other sagittal plane measures and the risk of ACL injuries with a prospective study design is lacking. Purpose: To investigate the relationship between selected sagittal plane hip, knee, and ankle biomechanics and the risk of ACL injury in young female team-sport athletes. Study Design: Case-control study; Level of evidence, 3. Methods: A total of 171 female basketball and floorball athletes (age range, 12-21 years) participated in a vertical drop jump test usin…
Promoting the Flexibility of Thermal Prosumers Equipped with Heat Pumps to Support Power Grid Management
2023
The increasing share of renewable energy sources in energy systems will lead to unpredictable moments of surplus/deficit in energy production. To address this issue, users with heat pumps can provide support to power grid operators through flexible unit operation achieved via Demand Response programs. For buildings connected to low-temperature heating networks with ensured third-party access, further room for flexibility can be explored by investigating the production of surplus heat that can be sold to the network. A key aspect lies in the identification of the energy pricing options that could encourage such flexible operation of a heat pump by “thermal prosumers”. To this aim…
Flexible Perfluoropolyethers-Functionalized CNTs-Based UHMWPE Composites: A Study on Hydrogen Evolution, Conductivity and Thermal Stability
2022
Flexible conductive composites based on ultra-high molecular weight polyethylene (UHMWPE) filled with multi-walled carbon nanotubes (CNTs) modified by perfluoropolyethers (PFPEs) were produced. The bonding of PFPE chains, added in 1:1 and 2:1 weight ratios, on CNTs influences the dispersion of nanotubes in the UHMWPE matrix due to the non-polar nature of the polymer, facilitating the formation of nanofillers-rich conductive pathways and improving composites’ electrical conductivity (two to five orders of magnitude more) in comparison to UHMWPE-based nanocomposites obtained with pristine CNTs. Electrochemical atomic force microscopy (EC-AFM) was used to evaluate the morphological changes dur…
Análisis del papel mediador de las capacidades de innovacion tecnológica en la relación entre la form’a organizativa flexible y el desempeño organiza…

ResumenEste trabajo examina la relación entre la forma organizativa flexible y el desempeño organizativo tomando como variables mediadoras las capacidades para la innovación tecnológica, basándose para ello en los postulados del Enfoque Basado en Recursos. Esta cuestión de investigación es importante porque nos permite comprender mejor las variables antecedentes de la capacidad de innovación tecnológica relacionadas con el diseño organizativo y sus efectos en el desempeno organizativo. Para el contraste empírico se toma una muestra de 159 empresas industriales españolas y se modeliza un sistema de ecuaciones estructurales mediante la técnica Partial Least Squares (PLS). Los resultados muest…
Tailoring the excitation of fundamental flexural guide waves in coated bone by phase-delayed array: Two-dimensional simulations
2015
The fundamental flexural guided wave (FFGW) enables ultrasonic assessment of cortical bone thickness. In vivo, it is challenging to detect this mode, as its power ratio with respect to disturbing ultrasound is reduced by soft tissue covering the bone. A phase-delayed ultrasound source is proposed to tailor the FFGW excitation in order to improve its power ratio. This situation is analyzed by 2D finite-element simulations. The soft tissue coating (7-mm thick) was simulated as a fluid covering an elastic plate (bone, 2–6 mm thick). A six-element array of emitters on top of the coating was excited by 50-kHz tone bursts so that each emitter was appropriately delayed from the previous one. Respo…
