Cyberbullying victimization research on individual and familial correlates is scarce in Spain. By building upon previous studies, this research examines the role of Internet usage and parental mediation in online victimization. Spanish children from rural public schools (10–12 years; n?=?1068) completed a self-report questionnaire which measured being cyberbullied, Internet use and parental mediation strategies. Logistic regression analyses examined the association among cyberbullying victimization, online activities, intensity and purposes of online communication, and restricting, evaluating and co-using parental mediation. The results show that Internet use, specifically online communication, increases the likelihood of cyberbullying victimization. Conversely, monitoring software installed on the computer, joint creation of rules regarding the time spent online and personal information shared help lessen the likelihood of online victimization. The results are examined in the light of previous research, while implications for practice and future research are considered.  相似文献   

Living by learning, learning by living: The quest for meaning     

Roberto Carneiro 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2013,59(3):353-372

In our current age of rapid social, economic and technological change, including urbanisation, globalisation and information overload, human beings are more than ever seeking orientation and meaning. In this situation, education is the potential key to individual empowerment, cultural prosperity, social cohesion and economic development. Arguing for the learning city as the location where a real learning culture is being developed, the author of this article discusses the need to build a new citizenship involving democratic, social, egalitarian (gender-balanced), intercultural and environmental dimensions. Based on a new humanism, this new citizenship should be designed to overcome the exclusion of many in the interests of a few and enable a meaning-friendly evolution in our social institutions. Thus the means of knowing, understanding and being in the world of knowledge, which are essential for liberating the human mind, can be provided to everyone.  相似文献   

Preventive Conservation: People,Objects, Place and Time in the Philippines     

Nicole Tse  Ana Maria Theresa Labrador  Marcelle Scott  Roberto Balarbar 《文物保护研究》2018,63(5):274-281

ABSTRACT

Preventive conservation, with its origins grounded in the material fabric of cultural material, is in a period of transformation, with numerous practitioners, in and outside of the field of conservation, considering its broader and holistic objectives. The conventional tools for the assertion of preventive conservation principles, namely the assessment and management of risks to cultural material from the ‘ten agents of deterioration’, have a central focus on the primacy of physical materials and degradation, with less clear relationships with people, place, and time in their modelling. With a case study focus on collections in the Philippines, this paper argues for a practice of preventive conservation that incorporates a balanced assessment and broader thinking around the contexts of objects, people, place, and time. The case studies of ecclesiastical Church collections, and museum environments in the Philippines, demonstrate how the interdependency of objects, people, place and time forms a holistic and conceptual preventive conservation framework. Through a cyclic renegotiation of these four parameters, this paper speculates on the gaps and opportunities for an inclusive view of preventive conservation that is current and more sustainable.  相似文献

Validity and reliability of a novel optoelectronic device to measure movement velocity,force and power during the back squat exercise     

Roberto Laza-Cagigas  Mark Goss-Sampson  Eneko Larumbe-Zabala  Leke Termkolli 《Journal of sports sciences》2019,37(7):795-802

This study analysed the validity and reliability of a new optoelectronic device (Velowin) for the measurement of vertical displacement and velocity as well as to estimate force and mechanical power. Eleven trained males with Mean (SD) age = 27.4 (4.8) years, completed an incremental squat exercise test with 5 different loads (<30–90% of their 1?repetition maximum) while displacement and vertical velocity of the barbell were simultaneously measured using an integrated 3D system (3D motion capture system + force platform) and Velowin. Substantial to almost perfect correlation (concordance correlation coefficient = 0.75–0.96), root mean square error as coefficient of variation ±90% confidence interval ≤10% and good to excellent intraclass correlation coefficient = 0.84–0.99 were determined for all the variables. Passing and Bablock regression methods revealed no differences for average velocity. However, significant but consistent bias were determined for average or peak force and power while systematic and not proportional bias was found for displacement. In conclusion, Velowin, in holds of some potential advantages over traditionally used accelerometer or linear transducers, represents a valid and reliable alternative to monitor vertical displacement and velocity as well as to estimate average force and mechanical power during the squat exercise.  相似文献   

Efficacy of an intervention to improve fluency in children with developmental dyslexia in a regular orthography   总被引：1，自引：0，他引：1  

Tressoldi PE  Vio C  Iozzino R 《Journal of learning disabilities》2007,40(3):203-209

The purpose of this study was to examine the efficacy of a method to improve reading fluency in children with dyslexia. The method, which we named "subsyllabic," was aimed at automatizing the recognition of syllables within words in connected texts, presented by ad hoc software. Two versions of this method--one self-paced and the other one with automatic syllable identification-were compared to a method based on phonemic awareness, assisted reading, and other psycholinguistic exercises. The efficacy of the two versions of the subsyllabic method was further studied by repeating the first version twice and the second version three times using an AB design, with each phase lasting approximately 3 months. This part of the study provided not only follow-up data but also useful information on if and how fluency may change after repeated treatment. Outcomes obtained by a total of 63 children with dyslexia suggested that the subsyllabic method was superior to the control method and that the use of an automatic presentation of target syllables produced better results. Furthermore, we observed that fluency improved approximately at the same rate after each treatment repetition. Our data support the possibility of improving reading fluency at a significant clinical level, at least for regular orthographies. The crucial component of the subsyllabic method seems to be the facilitation of syllable recognition within words in connected texts and the emphasis on their rapid recognition using an automatized procedure.  相似文献   

A simple and efficient device for demonstrating cross‐sectional anatomy of the head     

Ariane Zamarioli  Aline Santos Demaman  Waldeci Roberto Bim  Jefferson Mallman Homem  Jose Antonio Thomazini 《Anatomical sciences education》2010,3(3):141-143

Described in this article is a novel device that facilitates study of the cross‐sectional anatomy of the human head. In designing our device, we aimed to protect sections of the head from the destructive action of handling during anatomy laboratory while also ensuring excellent visualization of the anatomic structures. We used an electric saw to create 15‐mm sections of three cadaver heads in the three traditional anatomic planes and inserted each section into a thin, perforated display box made of transparent acrylic material. The thin display boxes with head sections are kept in anatomical order in a larger transparent acrylic storage box containing formaldehyde solution, which preserves the specimens but also permits direct observation of the structures and their anatomic relationships to each other. This box‐within‐box design allows students to easily view sections of a head in its anatomical position as well as to examine internal structures by manipulating individual display boxes without altering the integrity of the preparations. This methodology for demonstrating cross‐section anatomy allows efficient use of cadaveric material and technician time while also giving learners the best possible handling and visualization of complex anatomic structures. Our approach to teaching cross‐sectional anatomy of the head can be applied to any part of human body, and the value of our device design will only increase as more complicated understandings of cross‐sectional anatomy are required by advances and proliferation of imaging technology.

Demonstration of a new biosensing concept for immunodiagnostic applications based on change in surface conductance of antibodies after biomolecular interactions     

Vashist SK  Kaur I  Bajpai RP  Bharadwaj LM  Tewari R  Raiteri R 《Journal of Zhejiang University. Science. B》2006,7(9):683-685

We report an important observation that the surface conductivity of antibody layer immobilized on polylysine-coated glass substrate decreases upon the formation of complex with their specific antigens. This change in conductivity has been observed for both monoclonal and polyclonal antibodies. The conductance of monoclonal mouse IgG immobilized on polylysine-coated glass substrate changed from 1.02×10⁻⁸ Ω⁻¹ to 1.41×10⁻¹¹ Ω⁻¹ at 10 V when complex is formed due to the specific biomolecular interactions with rabbit anti-mouse IgG F(ab′)₂. Similar behavior was observed when the same set up was tested in two clinical assays: (1) anti-Leishmania antigen polyclonal antibodies taken from Kala Azar positive patient serum interacting with Leishmania promastigote antigen, and (2) anti-p21 polyclonal antibodies interacting with p21 antigen. The proposed concept can represent a new immunodiagnostic technique and may have wide ranging applications in biosensors and nanobiotechnology too.  相似文献   

Mechanical and EMG responses of the vastus lateralis and changes in biochemical variables to isokinetic exercise in endurance and power athletes     

Rainoldi A  Gazzoni M  Merletti R  Minetto MA 《Journal of sports sciences》2008,26(3):321-331

Twelve endurance athletes and six power athletes performed fatiguing isokinetic knee flexions/extensions. Isokinetic torque was recorded during the exercise. Isometric torque, cortisol and lactate responses, electromyographic (EMG) mean power frequency, average rectified value, and conduction velocity were analysed before and after the isokinetic exercise to determine correlations between electrophysiological variables and mechanical performances and/or blood concentrations of biomarkers in the two groups of athletes. The EMG variables were estimated from signals recorded from the vastus lateralis in both voluntary and electrically elicited isometric contractions. Power athletes recorded higher values than endurance athletes for the following variables: pre-exercise isometric maximal voluntary contraction (MVC), isokinetic MVC, rate of mechanical fatigue during isokinetic contractions, pre - post exercise variations and recovery times of conduction velocity and mean power frequency, and lactate concentrations. Moreover, conduction velocity overshooting was observed in endurance athletes during the recovery phase after exercise. The correlation analyses showed that the higher the rate of mechanical fatigue, the higher the lactate production and the reduction in conduction velocity due to the exercise.  相似文献
