Adolescents' credibility justifications when evaluating online texts.
2022
AbstractResearch has shown that students differ in their abilities to evaluate the credibility of online texts, and, in general, many perform poorly on online evaluation tasks. This study extended current knowledge by examining students’ abilities to justify the credibility of online texts from different perspectives, thus providing a more nuanced understanding of students’ credibility evaluation ability. We examined how upper secondary school students (N = 73; aged 16 to 17) evaluated author expertise, author intention, the publication venue, and the quality of evidence when reading four texts about the effects of sugar consumption in a web-based environment. Additionally, we examined how …
Exploring early adolescents’ evaluation of academic and commercial online resources related to health
2018
This study assessed the ability of 426 students (ages 12–13) to critically evaluate two types of online locations on health issues: an academic resource and a commercial resource. The results indicated limited evaluation abilities, especially for the commercial resource, and only a small, partial association with prior stance and offline reading ability. Only about half (51.4%) of the students questioned the credibility of the commercial online resource and only about 19% of the students showed an ability to fully recognize commercial bias. Wide variation existed in students’ ability to evaluate online information, as approximately one-fourth of the students performed poorly when evaluating…
Exploring the Collaborative Synthesis of Information During Online Reading
2019
This descriptive study sought to understand the complexities of integrative processing during collaborative online reading. Student pairs constructed a collaborative understanding while reading online information about a controversial issue by connecting, combining and organizing information that originated from prior knowledge, self-selected online texts, and discussions during an online inquiry task. Thirty-eight students from an upper secondary school in Finland worked in pairs to read online information and write an essay with the help of an argument graph tool. Primary data sources consisted of: prior knowledge; discussions; notes recorded with a graphic representational tool; video ca…
New is not always costly: evidence from online processing of topic and contrast in Japanese.
2013
Two visual ERP experiments were conducted to investigate topic and contrast assigned by various cues such as discourse context, sentential position and marker during referential processing in Japanese. Experiment 1 showed that there was no N400-difference for new vs. given noun phrases (NPs) when the new NP was expected (contrastively focused) based on its preceding context and sentential position. Experiment 2 further revealed that the N400 for new NPs can be modulated by the NP’s contrastive meaning (exhausitivity) induced from the marker. Both experiments also showed that new NPs engendered an increased Late Positivity. The reduced N400 for new vs. given supports an expectation-based lin…
On elliptic equations involving the 1-Laplacian operator
2018
El objetivo de esta tesis doctoral es dar a conocer los resultados obtenidos sobre existencia, unicidad y regularidad de las soluciones de diferentes ecuaciones elípticas regidas por el operador 1-laplaciano. El primer capítulo está dedicado al estudio de la ecuación - div (Du/|Du|) + g(u) |Du| = f(x) en un subconjunto abierto y acotado U de R^N con frontera Lipschitz, con la condición de Dirichlet u=0 en la frontera, tomando una función f positiva y siendo g una función real, continua y positiva. Por un lado, obtenemos soluciones no acotadas cuando el dato f pertenece al espacio de Marcinkiewicz L^{N,\infty}(U), por lo que debemos introducir la definición apropiada para este tipo de soluci…
LEADERSHIP STYLES IN SYNCHRONOUS AND ASYNCHRONOUS VIRTUAL LEARNING ENVIRONMENTS
2013
A comparison of the effects of transactional and transformational leadership in synchronous and a synchronous online teamwork was conducted. In the study, groups of four participants interacted in online text chat and online text forum in problem solving tasks. The groups were leaded by a confederate who acted as a transactional or a transformational leader. Satisfaction in the interactions and participations communicative styles were assessed. Results indicated that transformational leadership is more satisfying and cognitive and metacognitive style oriented than transactional leadership that is more participative style oriented.
The Effects of Consumer Demographics and Payment Method Preference on Product Return Frequency and Reasons in Online Shopping
2021
In online shopping, product returns are very common. In order to reduce them, one must first understand who are making them and why are they being made. In this study, we aim to address these questions by examining product return behaviour from a consumer-centric rather than the more traditional product-centric, retailer-centric, and order-centric perspectives. More specifically, we focus on the effects of four demographic characteristics of consumers (i.e., gender, age, education, and income) as well as their payment method preference on their product return frequency and product return reasons. As the data, we use the responses from 560 Finnish online consumers, which were collected with …
Nonlinear evolution equations for turbulent superfluids
2010
In this paper a system of evolution equations for turbulent superfluid helium is written in the nonlinear regime, choosing as fundamental fields the density, the velocity, the heat flux, the non-equilibrium temperature and the average vortex line density per unit volume. Approximate equations are written, where second order terms in the non-equilibrium quantities are retained.
Video Recruitment : Online Perspectives and Implications for Employer Branding
2022
Video recruitment—the use of videos at any point in the recruitment process—has surged among organizations as a strategy for hiring talent and operating in their respective fields amid the pandemic. In particular, video interviews have become mainstream at the assessment stage of the recruitment funnel to keep hiring workers in a remote context of work. Among job video interviews, the asynchronous type especially raised interest and concerns online. This chapter offers a novel and essential approach to the study of video interviews through the theoretical exploration of the crossover between HRM, marketing, and information technology, with the goal of uncovering several ways that employer b…
A Computationally Efficient Online/Offline Signature Scheme for Underwater Wireless Sensor Networks
2022
Underwater wireless sensor networks (UWSNs) have emerged as the most widely used wireless network infrastructure in many applications. Sensing nodes are frequently deployed in hostile aquatic environments in order to collect data on resources that are severely limited in terms of transmission time and bandwidth. Since underwater information is very sensitive and unique, the authentication of users is very important to access the data and information. UWSNs have unique communication and computation needs that are not met by the existing digital signature techniques. As a result, a lightweight signature scheme is required to meet the communication and computation requirements. In this researc…
