Reading Aloud Narrative Material as a Means for the Student's Cognitive Empowerment

Listening to stories and brain processing of narrative material activates many areas devoted not only to the linguistic processing. In this sense, it could be hypothesized that if this activity would be integrated within the school curricula, it could bring benefits in terms of understanding the text as well as in basic essential cognitive dimensions. In a series of studies with different age groups, we investigated the effects of an intensive training in narrative listening, through different tools such as the standardized tests of understanding of the text. We also used a neuropsychological battery investigating basic cognitive processes (cognitive assessment system) that are directly related to the ability of text comprehension. Results show a significant improvement in all tests for all age groups in the experimental groups, in comparison with the control groups.     

Development of an Interdisciplinary, Intercultural Master’s Program on Sustainability: Learning from the Richness of Diversity

The purpose of this article is to describe a joint effort between three European and six Latin American universities to create an international Master’s degree program on Sustainable Development and Management. Faculty members from these institutions are working together on this unusual and innovative project, which recognizes the importance of ICT (Information and Communication Technology) tools in international projects and programs. The article provides information about the ongoing interdisciplinary and intercultural dialogue and the learning process that is occurring throughout the development of the program.

Designing instruction for complex learning: 4C/ID in higher education

Objectives‐based instructional design approaches break down tasks into specific learning objectives and prescribe that instructors should choose the optimal instructional method for teaching each respective objective until all objectives have been taught. This approach is appropriate for many tasks where there is little relation between the objectives, but less effective for teaching complex professional tasks that require the integration of knowledge, skills, and attitudes and the coordination of different skills. For the latter, a task‐centred approach that starts designing instruction from whole, real‐life tasks, is more appropriate. This article describes one task‐centred instructional design model, namely the Four‐Component Instructional Design (4C/ID) model and illustrates its application by reflecting on three educational programs in higher education designed with 4C/ID. The first case presents a design for a course that focuses on the development of mobile apps at the Amsterdam University of Applied Sciences in the Netherlands. The second case illustrates the integration of information problem‐solving skills at Iselinge University of Professional Teacher Education, a teacher training institute in the Netherlands. The third case is an example from general practice education at the KU Leuven, Belgium. Future developments and issues concerning the implementation of task‐centred educational programmes are discussed.     

Vocation in Theology and Psychology: Conflicting Approaches?

ABSTRACT

Recent contributions in the fields of psychology, sociology, and theology reveal opposing attitudes about the subject of calling or vocation with regard to one's work. Whereas psychologists have rediscovered the concept, theologians increasingly show reluctance to accept a vocational view of work. In offering an alternative perspective, this article argues that an approach to calling from biblical theology is capable of inspiring Christian workers in a psychologically meaningful way, while avoiding the inadequacies of the understanding that “work is vocation” that was developed during the Protestant Reformation. In a biblical-theological approach, work is not equated with calling. Rather, it is perceived as practicing the love command and hope for a restoration of God's intentions for creation, emanating from the call into fellowship with Christ and a vision for the kingdom of God.     

The influence of content organization on student's cognitive structure in thermodynamics

Two different approaches to the content of thermodynamics were used in an introductory college physics course: one was the traditional organization found in most textbooks on the subject, the other was based on the learning theory of David Ausubel. The influence of these different content organizations on the student's cognitive structure was investigated using a word association test which was analysed through hierarchical clustering analysis. Research findings suggest that the approach based on Ausubel's theory influences the student's cognitive structure in such a way that their conceptual hierarchies are more coherent with the basic laws and the conceptual structure of the subject matter.     

Robust Visual Servoing of Robot Manipulators with Neuro Compensation

This paper considers the problem of visual servoing of planar robot manipulators in the presence of uncertainty associated with robot dynamics, camera system and Jacobian matrix. By using radial basis function neural networks, these uncertainties can be compensated effectively. Two kinds of robust visual servoing are proposed, one is for image uncertainties, another is for Jacobian matrix uncertainty. By Lyapunov method and input-to-state stability technique, we prove that these robust controllers with neural compensators are stable. Real-time experiments are presented to show the applicability of the approach presented in this paper.     

The skill bias effect of technological and organisational change: Evidence and policy implications

Previous studies have suggested that technological change is the main cause of the recent increase in demand for highly skilled workers in developed countries. However, a more recent strand of literature has also introduced the “Skill Biased Organisational Change” hypothesis, according to which the increasing diffusion of new organisational practices within firms plays a role in the increasing demand for skilled workers. We estimate a SUR model for a sample of 400 Italian manufacturing firms, showing that upskilling is more a function of reorganisational strategy than a consequence of technological change alone. Moreover, some evidence of superadditive effects emerges, which is consistent with the notion that technology and organisation jointly affect the demand for labour.     

Self-citations as strategic response to the use of metrics for career decisions

There is limited knowledge on the extent to which scientists may strategically respond to metrics by adopting questionable practices, namely practices that challenge the scientific ethos, and the individual and contextual factors that affect their likelihood. This article aims to fill these gaps by studying the opportunistic use of self-citations, i.e. citations of one’s own work to boost metric scores. Based on sociological and economic literature exploring the factors driving scientists’ behaviour, we develop hypotheses on the predictors of strategic increase in self-citations. We test the hypotheses in the Italian Higher Education system, where promotion to professorial positions is regulated by a national habilitation procedure that considers the number of publications and citations received. The sample includes 886 scientists from four of science’s main disciplinary sectors, employs different metrics approaches, and covers an observation period beginning in 2002 and ending in 2014. We find that the introduction of a regulation that links the possibility of career advancement to the number of citations received is related to a strong and significant increase in self-citations among scientists who can benefit the most from increasing citations, namely assistant professors, associate professors and relatively less cited scientists, and in particular among social scientists. Our findings suggest that while metrics are introduced to spur virtuous behaviours, when not properly designed they favour the usage of questionable practices.     

Stability of memristor neural networks with delays operating in the flux-charge domain

The paper considers a class of neural networks where flux-controlled dynamic memristors are used in the neurons and finite concentrated delays are accounted for in the interconnections. Goal of the paper is to thoroughly analyze the nonlinear dynamics both in the flux-charge domain and in the current-voltage domain. In particular, a condition that is expressed in the form of a linear matrix inequality, and involves the interconnection matrix, the delayed interconnection matrix, and the memristor nonlinearity, is given ensuring that in the flux-charge domain the networks possess a unique globally exponentially stable equilibrium point. The same condition is shown to ensure exponential convergence of each trajectory toward an equilibrium point in the voltage-current domain. Moreover, when a steady state is reached, all voltages, currents and power in the networks vanish, while the memristors act as nonvolatile memories keeping the result of computation, i.e., the asymptotic values of fluxes. Differences with existing results on stability of other classes of delayed memristor neural networks, and potential advantages over traditional neural networks operating in the typical voltage-current domain, are discussed.     

Effectiveness of pedalling retraining in reducing bilateral pedal force asymmetries

ABSTRACT

Previous studies have been limited to describe asymmetries during pedalling and suggest possible repercussion on performance and/or injury risks. However, few studies have presented strategies to mitigate asymmetries. The purpose of this study was to assess the effectiveness of a pedalling retraining intervention to reduce bilateral pedal force asymmetries. Twenty cyclists were assessed and 10 enrolled in a pedalling retraining method receiving visual and verbal feedback of pedal forces. The asymmetry index was computed for comparison of bilateral peak pedal forces and used during retraining (12 trials at 70% of peak power). Significantly larger asymmetry was observed for asymmetrical cyclists at the first three trials (P < 0.01 and ES = 1.39), which was reduced when post-retraining was compared to measures from symmetrical cyclists (P = 0.69 and ES = 0.18). Cyclists with larger asymmetry (>20%) in bilateral pedal forces reduce their asymmetries using sessions of pedalling retraining and achieve asymmetry indices similar to symmetrical cyclists.
