Teachers’ Evidence-Based Actions

2013

Currently, there is a dynamic development in the German school system. It is a new governance model which has been designed to have measurable effects on the political regulation of education.

Ready to Go? Schools’ Preparedness for Teaching and Learning Within a One-to-One Program

2020

Part 6: ICT and Education; International audience; During the years there has been an increasing number of one-to-one programs around the world. In such programs all students are equipped with portable devices, such as laptops, tablets, smartphones for learning purposes. Even if these initiatives are increasing, our knowledge of the impact of such digital transformation of education is still little studied. Based on data from a three years longitudinal study on a large-scale implementation of Chromebooks in a municipality, this paper highlights teachers’ experiences. Key findings suggest that this initiative has been successful when it comes to the administrative and technical implementatio…

First Life Cycle Impact Considerations of Two Wave Energy Converters

2018

The work presents two different revolutionary devices for the utilization of a new entry of renewable energy sources: sea wave. The first technology is based on linear generators, able to directly converts a linear motion into electrical output, limiting to minimum the chain of energy conversion. The other solution is based on a mechanical motion converter, coupled with alternators. The scope of this paper is to compare the two different systems designed by University of Palermo, through Life Cycle Assessment, in order to evaluate the global effects of the two systems to the environment.

Self-Efficacy and Resilience: Mediating Mechanisms in the Relationship Between the Transformational Leadership Dimensions and Well-Being

2019

The objective of this article is to test the roles of self-efficacy and resilience as consecutive mediators in the relationship between the four dimensions of transformational leadership and well-being (operationalized as psychosomatic complaints and psychological distress). The sample consists of 225 social services employees in Spain. Data were gathered at two time points with a time-lag of 6 months. We used path analysis to test the hypothesized model and Monte Carlo confidence intervals to check the significance of the indirect effects. Our results showed that only two of the four transformational leadership dimensions have a direct impact on self-efficacy: inspirational motivation and…

Linking transformational leadership to nurses’ extra-role performance: the mediating role of self-efficacy and work engagement

2011

salanova m., lorente l., chambel m.j. & martinez i.m. (2011) Linking transformational leadership to nurses’ extra-role performance: the mediating role of self-efficacy and work engagement. Journal of Advanced Nursing 67(9), 2256–2266. Abstract Aims.  This paper is a report of a social cognitive theory-guided study about the link between supervisors’ transformational leadership and staff nurses’ extra-role performance as mediated by nurse self-efficacy and work engagement. Background.  Past research has acknowledged the positive influence that transformational leaders have on employee (extra-role) performance. However, less is known about the psychological mechanisms that may explain the lin…

Properties of hyperons in chiral perturbation theory

2009

The development of chiral perturbation theory in hyperon phenomenology has been troubled due to power-counting subtleties and to a possible slow convergence. Furthermore, the presence of baryon-resonances, e.g. the lowest-lying decuplet, complicates the approach, and the inclusion of their effects may become necessary. Recently, we have shown that a fairly good convergence is possible using a renormalization prescription of the loop-divergencies which recovers the power counting, is covariant and consistent with analyticity. Moreover, we have systematically incorporated the decuplet resonances taking care of both power-counting and $consistency$ problems. A model-independent understanding o…

Oxidative stress in environmental-induced carcinogenesis.

2009

Reactive oxygen species (ROS) are the more abundant free radicals in nature and have been related with a number of tissue/organ injuries induced by xenobiotics, ischemia, activation of leucocytes, UV exposition, etc. Oxidative stress is caused by an imbalance between ROS production and a biological system's ability to readily detoxify these reactive intermediates or easily repair the resulting damage. Thus, oxidative stress is accepted as a critical pathophysiological mechanism in different frequent human pathologies, including cancer. In fact ROS can cause protein, lipid, and DNA damage, and malignant tumors often show increased levels of DNA base oxidation and mutations. Different lifesty…

Is chlamydial heat shock protein 60 a risk factor for oncogenesis?

2004

Heat shock protein 60 (HSP60) plays an important role in the protein folding of prokaryotic and eukaryotic cells. Most of the papers published on chlamydial HSP60 concern its role in immune response during infection. In the last decade, exposure to Chlamydia trachomatis has been consistently associated with the development of cervical and ovarian cancer. Moreover, it has been suggested that chlamydial HSP60 may have an anti- apoptotic effect during persistent infection. We hypothesize that the accumulation of exogenous chlamydial HSP60 in the cytoplasm of actively replicating eukaryotic cells may interfere with the regulation of the apoptotic pathway. The concomitant expression of viral onc…

Employee-driven digitalization in healthcare: codesigning services that deliver

2020

Abstract The purpose of this article is to explore and conceptualize how Nordic principles of employee participation combined with enterprise social media/web 2.0 could enable co-creation as an input to digital transformation of healthcare services. The question of how to enable effective co-creation is both under-researched and stated as an important enabler of digitalization and service improvements. The article starts by introducing The Nordic Model for employee participation that is proven successful for enhancing working life effectiveness and innovation. We then discuss how these principles of participation can be further enhanced by state-of-the-art web 2.0 technologies for Enterpris…
