‘I think we are still very directive’: Teachers’ discourses on democratic student participation

The objective of this study [Susinos, T. (Dir.), ‘Schools moving towards inclusion: Learning from the local community, the student voice and educational support’ (I+D+I, EDU2011-29928-C03-03)] is to gain a deeper understanding of the analysis of the discourses that different education professionals in the Spanish education system have on student participation in schools, based on the premise that they tacitly reflect different models of democracy and advance very diverse school practices. The study is based on the Student Voice Movement, which is defined by its commitment to deliberative democratic education and its role in the development of inclusive schools. In this article, we have conducted a qualitative analysis of the data from 31 in-depth interviews carried out with teachers and other education professionals from nine schools. These teachers’ discourses are summarised in four dimensions, which we have named individual, pedagogical, organisational and socio-political. Some conclusions of this work demonstrate a predominance of discourses linked to an individual and pedagogical dimension of participation, based on the idea that this fundamentally depends on the personal dispositions that some students have. It is less common to appeal to the socio-political dimension, which refers to participation as a citizen's right to debate and make decisions regarding common and public affairs. This suggests that teachers still see their work from a technical point of view, rather than envisaging the school as a space for democratic participation and practice. In short, with this study we aim to contribute to normative theories on participation and democracy in order to expand their empirical and practical support in schools.

Mapping of quantitative trait loci using the skew-normal distribution

In standard interval mapping (IM) of quantitative trait loci (QTL), the QTL effect is described by a normal mixture model. When this assumption of normality is violated, the most commonly adopted strategy is to use the previous model after data transformation. However, an appropriate transformation may not exist or may be difficult to find. Also this approach can raise interpretation issues. An interesting alternative is to consider a skew-normal mixture model in standard IM, and the resulting method is here denoted as skew-normal IM. This flexible model that includes the usual symmetric normal distribution as a special case is important, allowing continuous variation from normality to non-normality. In this paper we briefly introduce the main peculiarities of the skew-normal distribution. The maximum likelihood estimates of parameters of the skew-normal distribution are obtained by the expectation-maximization (EM) algorithm. The proposed model is illustrated with real data from an intercross experiment that shows a significant departure from the normality assumption. The performance of the skew-normal IM is assessed via stochastic simulation. The results indicate that the skew-normal IM has higher power for QTL detection and better precision of QTL location as compared to standard IM and nonparametric IM.     

Fostering Counseling Students' Career Information Literacy Through a Comprehensive Career Web Site

Counseling students need to become knowledgeable about existing online career development tools to provide effective career development services today. The authors describe the characteristics of a Web site developed to foster career information literacy among students taking graduate career courses and examine its academic usefulness. Student evaluations suggest that the Web site is useful in promoting career information literacy and knowledge. Students who used the Web site showed a significant gain in perceived self‐knowledge as well as in actual knowledge of career information. Ways of using the career Web site to improve students' knowledge of online career resources are explored.     

Relationships between religion,risk behaviors and prosociality among secondary school students in Peru and El Salvador

How young people spend time out of school is important for their character development. In this article we explore the relationships between adolescents’ leisure time and other aspects of their lives, with a particular focus on religion. Using a data set generated by secondary school students in Peru and El Salvador (n = 6085) for a public health project, YOURLIFE, we conducted multiple logistic regression analyses of the relationships between religious identification, salience and practice; five indicators of adolescent risk behaviors; and, four indicators of prosocial attitudes and behaviors. In addition to not participating in risk behaviors such as sex, smoking, drinking alcohol and taking illicit drugs, these analyses show significant relationships between religion and prosocial activities and attitudes. These data are considered in the context of the wider debate over the role of religion in adolescent character development in Latin America and elsewhere.     

Developing Counseling Students' Multicultural Competence Through the Multicultural Action Project

The Multicultural Action Project (MAP) is a cultural immersion project that requires counseling students to engage with diverse cultural communities on 3 levels: observation, information seeking, and action. To ascertain if participating in MAP improved the multicultural competence of graduate counseling students, the authors conducted an evaluation in which narrative analysis was used to examine the experiences of 3 graduate counseling students who participated in MAP. Through their narratives, the participants reported increased knowledge, awareness, and skills. The importance of sustained contact and interpersonal relationships in improving student learning outcomes is discussed and recommendations are provided.     

A cross-cultural study on the influence of cultural values and teacher beliefs on university teachers’ information and communications technology acceptance

This study examined how cultural values and teacher beliefs influence Chinese and Spanish university teachers’ acceptance of ICTs by combining Hofstede’s cultural values theory with technology acceptance theories. Four hundred and twenty-five university teachers from China and 385 teachers from Spain participated in the study. The proposed research model was tested by using samples from both countries and the multigroup analyses were performed to test moderating effects of cultural variables. Results confirmed the validity of the model in both samples and the effects of cultural values on the adoption of ICTs, and significant differences were observed between the two samples.

     

Science curriculum reform as a socioculturally anchored practice

In this essay I elaborate on three ideas that emerged from reading the work of Sylvie Barma. These points are in response to curriculum reform and the use of activity theory: (a) curriculum reform as a public policy; (b) a reflection about the process followed by teacher implementation of that reform in a biology classroom; and (c) the sense of experience as an objective anchored in activity theory. This commentary deals with several entanglements of science teaching and learning where I am also able to address some of my own queries in the use of activity theory in research.     

Robust stability analysis of formation control in local frames under time-varying delays and actuator faults

This paper investigates the robust stability of a multiagent system moving to a desired rigid formation in presence of unknown time-varying communication delays and actuator faults. Each agent uses relative position measurements to implement the proposed control method, which does not require common coordinate references. However, the presence of time delays in the measurements, which is inherent to the communication links between agents, has a negative impact in the control system performance leading, in some cases, to instability. Furthermore, the robust stability analysis becomes more complex if failures on actuators are taken into account. In addition, delays may be subject to time variations, depending on network load, availability of communication resources, dynamic routing protocols, or other environmental conditions. To cope with these problems, a sufficient condition based on Linear Matrix Inequalities (LMI) is provided to ensure the robust asymptotic convergence of the agents to the desired formation. This condition is valid for any arbitrarily fast time-varying delays and actuator faults, given a worst-case point-to-point delay. Finally, simulation results show the performance of the proposed approach.     

Microfluidic model of monocyte extravasation reveals the role of hemodynamics and subendothelial matrix mechanics in regulating endothelial integrity

Extravasation of circulating cells is an essential process that governs tissue inflammation and the body''s response to pathogenic infection. To initiate anti-inflammatory and phagocytic functions within tissues, immune cells must cross the vascular endothelial barrier from the vessel lumen to the subluminal extracellular matrix. In this work, we present a microfluidic approach that enables the recreation of a three-dimensional, perfused endothelial vessel formed by human endothelial cells embedded within a collagen-rich matrix. Monocytes are introduced into the vessel perfusate, and we investigate the role of luminal flow and collagen concentration on extravasation. In vessels conditioned with the flow, increased monocyte adhesion to the vascular wall was observed, though fewer monocytes extravasated to the collagen hydrogel. Our results suggest that the lower rates of extravasation are due to the increased vessel integrity and reduced permeability of the endothelial monolayer. We further demonstrate that vascular permeability is a function of collagen hydrogel mass concentration, with increased collagen concentrations leading to elevated vascular permeability and increased extravasation. Collectively, our results demonstrate that extravasation of monocytes is highly regulated by the structural integrity of the endothelial monolayer. The microfluidic approach developed here allows for the dissection of the relative contributions of these cues to further understand the key governing processes that regulate circulating cell extravasation and inflammation.
