Security in Modern Smart Cities: An Information Technology Perspective
2019
In a big and modern city, the security system is not a single-layered single module system. Instead, it consists of many layers with autonomous subsystems which are capable of interfacing reciprocally in an efficient and coordinated way horizontally and vertically. The design of such indigenous subsystems and ensuring tight interaction between them while taking into account high usability and resource utilization is not a simple task. In this regard, this article provides a comprehensive overview of the security systems in smart cities. We begin by introducing trends and key stakeholders in smart cities. Next, we provide examples of mass surveillance systems in developed countries like the …
A Novel Bio-Inspired Approach for High-Performance Management in Service-Oriented Networks
2021
Service-continuity in distributed computing can be enhanced by designing self-organized systems, with a non-fixed structure, able to modify their structure and organization, as well as adaptively react to internal and external environment changes. In this paper, an architecture exploiting a bio-inspired management approach, i.e., the functioning of cell metabolism, for specialized computing environments in Service-Oriented Networks (SONs) is proposed. Similar to the processes acting in metabolic networks, the nodes communicate to each other by means of stimulation or suppression chains giving rise to emergent behaviors to defend against foreign invaders, attacks, and malfunctioning. The mai…
Why do we enjoy creative tasks? Results from a multigroup randomized controlled study
2016
Previous studies have linked positive emotions with creativity, but it remains unknown why creative activities may enhance positive emotions. We tested how creative tasks influence autonomous self-expression and task absorption, and whether this in turn increases positive emotions. Data from 478 participants were divided into four language samples (English, German, Italian, and Polish) and analyzed in a series of multigroup structural equation models. The indirect effects were replicated in all samples. Creative tasks enhanced positive emotions through an increase in autonomy. However, participants who solved creative tasks also reported lower task absorption, and this has hindered their ex…
Does orthographic processing emerge rapidly after learning a new script?
2021
Epub 2020 Aug 11 Orthographic processing is characterized by location-invariant and location-specific processing (Grainger, 2018): (1) strings of letters are more vulnerable to transposition effects than the strings of symbols in same-different tasks (location-invariant processing); and (2) strings of letters, but not strings of symbols, show an initial position advantage in target-in-string identification tasks (location-specific processing). To examine the emergence of these two markers of orthographic processing, we conducted a same-different task and a target-in-string identification task with two unfamiliar scripts (pre-training experiments). Across six training sessions, participants …
Summary versus argument tasks when working with multiple documents: Which is better for whom?
2010
Abstract This article reports on two experiments where undergraduates read five documents on a scientific topic and afterwards answered comprehension questions and wrote either summaries or argument essays on the topic. In the first experiment, students who were instructed to work with the documents for the purpose of summarizing their contents displayed better comprehension and integration of document contents than did students instructed to construct arguments from the documents. In the second experiment, focusing on whether the effects of task instructions on multiple-documents comprehension and integration could be moderated by students’ prior knowledge, it was found that only students …
Promoting sixth graders’ credibility evaluation of Web pages: An intervention study
2020
Abstract This study investigated whether a teacher-led intervention program on online inquiry improved sixth graders' performance in a credibility evaluation task. Students (N = 342) were divided into two conditions, an intervention group (190 students) and a control group (152 students). The intervention program (21 × 45 min lessons) was implemented during a six-week course as a part of normal schoolwork. The program included explicit teaching of online inquiry skills: searching for information (3 lessons), evaluating credibility of information (3 lessons), and synthesizing information (3 lessons). In addition, the skills taught were applied in two online inquiry projects comprising 12 les…
Questions raised in science education : a Colombian-Spanish comparative study
2016
RESUMEN: La formulación de preguntas es un potente recurso para el aprendizaje de las ciencias. El objetivo del presente trabajo fue evaluar el desarrollo de la competencia metacognitiva por medio de la formulación de preguntas. En este estudio se usaron dos dispositivos experimentales de ciencias con un comportamiento inesperado. Se pidió a los participantes realizar preguntas destinadas a comprender su funcionamiento. La evaluación contrastó el desempeño de estudiantes colombianos con estudiantes españoles equivalentes. Los resultados mostraron que los colombianos formulan significativamente más preguntas en general, y más preguntas de alta calidad, que los estudiantes españoles. Se concl…
Assessing dyslexia in Finnish high-school students: a pilot study
2000
A pilot study concerning Finnish dyslexics at senior high school (lukio), for 16–19-year-olds, is reported. The phonological processing deficit was assumed to underlie dyslexia in these late teenage subjects. The regular nature of Finnish orthography was taken into consideration. Four tasks were introduced to a total of 32 students, of whom 15 were dyslexics and 17 were controls. The controls outperformed the dyslexics on three tasks: text recoding, pseudoword recoding and pseudoword spelling. On the text spelling task, both groups performed equally well. In the correlational analysis of all subjects, both recoding tasks showed high correlations with selfestimated school achievement in lang…
Task-focused behaviour and literacy development: a reciprocal relationship
2009
University of Jyva¨skyla¨The purpose of this study was twofold: (a) to examine the effect of task-focusedbehaviour on reading fluency, spelling and comprehension; and (b) to examine therole of the different literacy skills in subsequent task-focused behaviour. Twohundred and seven Finnish-speaking children were followed from preschool untiltheir fourth year at school and were tested for reading fluency, spelling and readingcomprehension. The teachers also rated the children’s task-focused behaviour. Theresults showed that task-focused behaviour was a significant predictor of laterreading comprehension and spelling skills. However, all three literacy skillspredicted subsequent task-focused beha…
Representational flexibility in children's drawings: Effects of age and verbal instructions
1999
This study aims to investigate representational and syntactical flexibility in children's drawing behaviour, and the extent to which changes introduced at both representational and syntactical levels are related to age or can be induced by contextual manipulations. A Deletion task required three age groups of 5-, 7- and 9-year-old children to draw objects that had been rendered partially invisible, thanks to magic transformations. Two different verbal instructions about what was to remain visible in the objects, and two different objects, one regularly and one non-regularly drawn, were designed to investigate contextual sensitivity in children's representational and syntactical behaviour re…
