The implications of the local context in global virtual education
2012
<input id="gwProxy" type="hidden" /><input id="jsProxy" onclick="if(typeof(jsCall)=='function'){jsCall();}else{setTimeout('jsCall()',500);}" type="hidden" /><p>This paper investigates how features in students’ everyday life influence their participation in online global collaboration, and it suggests that students’ local context should be recognised as a significant part of their educational space. In this exploratory case study of students engaged in a global online master’s programme, the discussion is organised under three main headings: the social, material, and cultural dimensions of students’ daily life. The paper shows how the influence of the students’ local contex…
Digital knowledge sharing and creative performance: Work from home during the COVID-19 pandemic
2021
Abstract The outbreak of the COVID-19 pandemic and the resulting social distancing requirements have led to major disruptions in the world of work. The outcomes of the enforced and large-scale work from home (WFH) practices are currently largely unexplored. This study aims to address this gap in the research by investigating the external and internal digital knowledge sharing (DKS) and creative performance (CP) of employees under these extraordinary circumstances. The social capital theory was utilized as the theoretical lens for examining the associations of DKS and CP with demographic, individual, and organizational factors. An online cross-sectional survey was carried out among knowledge…
Identifying predictive factors in compliance with the COVID-19 containment measures: A mediation analysis
2021
Giusy Danila Valenti, Palmira Faraci Faculty of Human and Social Sciences, University of Enna âKoreâ, Enna, ItalyCorrespondence: Giusy Danila ValentiCittadella Universitaria, 94100, ItalyEmail giusy.valenti@unikore.itIntroduction: The outbreak of the COVID-19 pandemic has led governments to implement some containment measures to flatten the curve of the diffusion of the virus. The current study aims to investigate individual differences in compliance with these restrictive behaviors. In a sample of Italian individuals (N = 300), we examined whether sociodemographic factors, personality traits, fatalism, and fear could be considered as possible predictors.Methods: We performed a series o…
Self-isolation for the self-centered: Negative framing increases narcissists' willingness to self-isolate during COVID-19 through higher response eff…
2021
Abstract The coronavirus (COVID-19) pandemic has come with various health recommendations restricting personal freedom, such as social distancing and self-isolation. Considering the personal sacrifices involved, not all individuals are equally willing to comply with such recommendations, which might pose a health hazard further down the line. In a high-powered study (N = 800), we show that individual differences in narcissism influence the willingness to self-isolate during pandemics, with individuals high (vs. low) in narcissism being less willing to self-isolate. However, this tendency can be offset by tailored message framing. Specifically, individuals high (vs. low) in narcissism are mo…
The impact of COVID-19 quarantine on youth: from physical inactivity to pediatric depreobesity
2020
Objective : To comment on how COVID-19 quarantine has affected physical activity in youth and induced a pediatric depreobesity status. Key Points Scarce literature has described the impact of COVID-19 on youth levels of moderate to vigorous physical activity. Physical inactivity and social distancing could lead to physical and psychosocial problems increasing the risk of obesity and depression. Regular moderate to vigorous physical activity plays an essential role to limit or prevent the negative consequences of prolonged quarantine periods on pediatric depreobesity.
Tourism recovery amid COVID-19: The case of Lombardy, Italy
2021
Travel restrictions and social distancing imposed to curb the spread of the new coronavirus have been strongly hitting tourism since March 2020. Tourism forecasting literature addressed the effects of shocks in contexts characterized by a predictable route to recovery. COVID-19 is without precedents. In this article, monthly overnight stays for the period January 2010 to December 2020 are used to estimate the impact of the pandemic in Lombardy, Italy’s most affected region. A model-based approach is implemented, and the number of overnight stays up to December 2023 is forecasted. Four models are compared. Estimation results from an augmented SARIMA model suggest that, provided a new lockdo…
Improving protein secondary structure predictions by prediction fusion
2009
Protein secondary structure prediction is still a challenging problem at today. Even if a number of prediction methods have been presented in the literature, the various prediction tools that are available on-line produce results whose quality is not always fully satisfactory. Therefore, a user has to know which predictor to use for a given protein to be analyzed. In this paper, we propose a server implementing a method to improve the accuracy in protein secondary structure prediction. The method is based on integrating the prediction results computed by some available on-line prediction tools to obtain a combined prediction of higher quality. Given an input protein p whose secondary struct…
Information and hierarchical structure in financial markets
1999
I investigate the information content present in the time series of stock prices of a portfolio of stocks traded in a financial market. By investigating the correlation coefficient between pairs of stocks I provide a working definition of a generalized distance between the stocks of the portfolio. This generalized distance is used to obtain an ultrametric distance matrix between the stocks. The ultrametric structure of the portfolio investigated has associated a taxonomy which is meaningful from an economic point of view.
The clustering of galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: Measuring D_A and H at z=0.57 from the Baryon Acoustic Peak in th…
2014
We present measurements of the angular diameter distance to and Hubble parameter at z = 0.57 from the measurement of the baryon acoustic peak in the correlation of galaxies from the Sloan Digital Sky Survey III Baryon Oscillation Spectroscopic Survey. Our analysis is based on a sample from Data Release 9 of 264 283 galaxies over 3275 square degrees in the redshift range 0.43 z DA(0.57) = 1408 ± 45 Mpc and H(0.57) = 92.9 ± 7.8 km s-1 Mpc-1 for our fiducial value of the sound horizon. These results from the anisotropic fitting are fully consistent with the analysis of the spherically averaged acoustic peak position presented in Anderson et al. Our distance measurements are a close match to th…
ELDAR, a new method to identify AGN in multi-filter surveys: the ALHAMBRA test case
2017
We present ELDAR, a new method that exploits the potential of medium- and narrow-band filter surveys to securely identify active galactic nuclei (AGN) and determine their redshifts. Our methodology improves on traditional approaches by looking for AGN emission lines expected to be identified against the continuum, thanks to the width of the filters. To assess its performance, we apply ELDAR to the data of the ALHAMBRA (Advance Large Homogeneous Area Medium Band Redshift Astronomical) survey, which covered an effective area of 2.38 deg2 with 20 contiguous medium-band optical filters down to F814W ≃ 24.5. Using two different configurations of ELDAR in which we require the detection of at lea…
