Emotions experienced by preservice early childhood teachers during a training program in inquiry‐based science education
Get PDFThe influence of emotions on teaching –learning processes is a topic of increasing interest in science education research. This study explores the emotions experienced by 121 preservice early childhood teachers during a training program in inquiry-based science education. Using a checklist of nine emotions (both positive and negative), participants indicated the emotions they experienced at three stages of the instruction: at the outset, after experiencing an inquiry cycle as science learners, and after designing an inquiry cycle as teacher trainees. Only five of the emotions (interest, concentration, confidence, enjoyment, and insecurity) were reported at all three stages, and closer analysis showed that their prevalence varied depending on the phase of the inquiry cycle and the role that students were in (i.e., science learners or teacher trainees). In both roles, insecurity was generally associated with the initial phases of inquiry (problem formulation, designing experiments, and choosing variables); enjoyment was more prevalent during the phases of realization of the experience in the science learner role and of data analysis in the teacher trainee role; and confidence was particularly associated with the drawing conclusions phase in both roles. These results suggest that in order to understand preservice early childhood teachers' emotions in relation to inquiry-based science education, it is necessary to consider the different phases of inquiry, each of which may generate a different emotional response. When instructing preservice teachers in the use of inquiry tasks, their emotions are also likely to vary depending on whether they are engaging with the approach as science learners or teacher trainees.This work was supported by the Spanish Government (Ministerio de Ciencia, Innovación y Universidades/Agencia Estatal de Investigación), MCIN/AEI/10.13039/501100011033.

Icons for Software Implementations of Interactive Multiobjective Optimization Methods: A Semantic Distance Study
Get PDFMultiobjective optimization problems involve several conflicting objective functions to be optimised simultaneously and solu-tions to these problems represent different trade-offs. When applying interactive methods, a decision maker with domain exper-tise provides one's preference information over several iterations, according to which new solutions are computed until finding asolution with the most preferred trade-offs. Publications on interactive multiobjective optimization methods mainly focus on theoptimisation algorithm, and little attention is paid to their implementations, not to mention the development of user interfacesthat enable interaction with the decision maker. User interfaces involve icons but there are no studies about icons for the specificfunctionalities of multiobjective optimization methods. Icons convey meaning effectively to users interacting with technology.With these small pictorial representations, information on system functionalities is communicated quickly. However, the imme-diacy of icon recognition can also lead to misunderstandings and difficulties in using the system if they are not designed properly.Semantic distance in icon design indicates the closeness of the pictorial representation to its intended functionality and, thus,functions as the main principle in designing effective icons. An empirical study (N = 38) was conducted to examine the semanticdistances of icons for interactive multiobjective optimization methods implemented in an open-source software framework. Thestudy addressed the main functionalities. According to our main findings, we suggest an icon set for the considered functionali-ties, to enable fluent interaction with decision makers and other involved parties utilising interactive multiobjective optimizationmethods via user interfaces.Funding for open access charge: Universidad de Málaga / CBU
Modelos metabólicos a escala genómica como herramienta para el estudio de la interacción Podosphaera xanthii-Cucumis melo
Get PDFLos hongos fitopatógenos representan una gran amenaza para la producción agrícola a nivel global. Entre ellos, los oídios (familia Erysiphaceae) destacan por ser los agentes causales de la enfermedad homónima, que afecta a más de 10.000 especies de plantas. Este grupo de ascomicetos son biotrofos obligados, lo que significa que dependen completamente de su hospedador como resultado de una pérdida progresiva de genes del metabolismo primario. Sin embargo, los motivos que subyacen a la pérdida de tan solo ciertos genes es aún una cuestión abierta. En este trabajo, se presenta un modelo metabólico preliminar que describe la interacción entre Podosphaera xanthii, el principal responsable del oídio de las cucurbitáceas, y el melón (Cucumis melo). La reconstrucción del borrador permite explorar las asociaciones gen-proteína-reacción en los diferentes compartimentos celulares de ambos organismos, atendiendo también a los genes perdidos identificados en los oídios. Asimismo, el modelo posibilita la integración de datos transcriptómicos para simular los flujos de metabolitos que serían esenciales para el desarrollo del hongo. Este enfoque no solo permite conocer más sobre las capacidades metabólicas de P. xanthii, sino que también sienta las bases para la selección racional de genes diana en el diseño de estrategias de control de la enfermedad
Kinesiophobia, catastrophizing, and the duration of immobilization: A prospective study on factors associated with shoulder disability following wrist-hand injuries
Get PDFBackground
Shoulder pain is a major musculoskeletal problem after wrist-hand immobilization. There is limited evidence regarding the relationship of kinesiophobia or pain catastrophizing with shoulder pain and disability after wrist-hand injury.
Purpose
To explore associations between kinesiophobia and pain catastrophizing with ipsilateral persistent shoulder disability in patients with wrist-hand injury after 6 months.
Study Design
Prospective study.
Methods
Participants aged ≥18 years referred to hand therapy after wrist-hand injury requiring wrist-hand immobilization were recruited and completed the Numeric Pain Scale, Shoulder Pain and Disability Index, Pain Catastrophizing Scale (PCS), and Tampa scale for kinesiophobia (TSK) at baseline, after an immobilization period, and after 6 months.
Results
A total of 107 patients were included in the study. Scaphoid fractures were found in 49 (45.8%) of patients, and 58 (54.2%) had distal radius fractures. For each week of increased time spent in immobilization, the Shoulder Pain and Disability Index score increased by 10.2 points, 95% confidence interval (CI) [6.76, 13.57], with higher levels of immobilization being associated with increased shoulder pain and disability. The baseline TSK score was 17.4 and 11.2 at follow-up. The PCS score was initially 14.8 and decreased to 9.3 at follow-up. The addition of TSK and PCS to the predictive model led to a statistically significant increase in R2 of 0.163, F(2,100) = 47.471, p < 0.001.
Conclusions
The duration of wrist immobilization following an injury may play a crucial role in the level of shoulder disability experienced at the 6-month mark post-injury. This shoulder disability may be influenced by factors such as fear of movement.Funding for open access charge: Universidad de Málaga / CBU
'I Know that I Exist’: Lorna Gibb’s _A Ghost Story_ as an Assemblage of Matter and Spirit.
Get PDFIn this chapter I discuss Lorna Gibb’s _A Ghost Story_ (2015), which offers a different take on the story of the spirit celebrity, Katie (and John) King. In this novel the narrator is the disembodied voice of the ghost, a first-person narrative voice that moves in and out of time and place, that it plays a part in people’s lives, as well as possesses the body of several mediums and spiritualist believers in their seánces and theatrical acts, like those of the Davenport brothers. The novel shows a clear rejection of binaries such as human/nonhuman, matter/spirit, embodiment/disembodiment, and in so doing it underlines the fluidity of the multiple elements (bodies, parts, terms) involved in Spiritualism, and in séances particularly. My aim is to examine the shifting relations between those elements, as well as the tension between human-nonhuman, matter-spirit through an assemblage lens, drawing on social theorists such as Gilles Deleuze and Félix Guattari, as well as Bruno Latour.This essay is part of the grant PID2022-137881NB-I00, funded by MCIN/AEI/ 10.13039/501100011033 and, by “ERDF A way of making Europe” by the “European Union”

Emotional intelligence, motivation and learning strategies: The SSREI and MSLQ-SF questionnaires.
Get PDFPurpose: The influence of a good management of Emotional Intelligence (EI) on personal attitude shows a motivational impact that allows better results in any field, work, social or personal. This study analyzes EI and Motivation (MO) through the learning strategies present in 402 university students of the Faculty of Economics and Business and the Faculty of Commerce and Management (Malaga). It also analyzes the impact of gender on these results and identifies the dimensions of the variables studied.
Design/methodology/approach: For this purpose, we applied the motivational tools Motivated Strategies for Learning Questionnaire (MSLQ) and the Self-Report Emotional Intelligence Test (SSEIT).
Findings: From the identification of EI (5) and MO (4) dimensions, the results of this study indicate high levels of active participation and interest in the subject. Students show a desire to learn effectively and for their learning to be of quality, motivating and useful for understanding the world around them and applying that knowledge to improve it.
In relation to the impact of the gender factor, no significant differences or attitudinal patterns were found. Responses and behaviors were homogeneous for both genders.
Originality/value: This work identifies the dimensions of EI and MO of university students in terms of involvement, interest in the subject of study and use of learning tools. Confirming that these parameters influence academic performance, the results allow us to determine in which aspects it is necessary or advisable to work on. Attitudes, motivation and intelligent emotional management can provide a competitive advantage
Harnessing memetic algorithms: a practical guide
Get PDFThe aim of this work is to provide a didactic approximation to memetic algorithms (MAs) and how to apply these techniques to an optimization problem. MAs are based on the synergistic combination of ideas from population-based metaheuristics and trajectory-based search/optimization techniques. Most commonly, MAs feature a population-based algorithm as the underlying search engine, endowing it with problem-specific components for exploring the search space, and in particular with local-search mechanisms. In this work, we describe the design of the different elements of the MA to fit the problem under consideration, and go on to perform a detailed case study on a constrained combinatorial optimization problem related to aircraft landing scheduling. An outline of some advanced topics and research directions is also provided.Funding for open access publishing: Universidad de Málaga/CBUA.
