Desired cybersecurity skills and skills acquisition methods in the organizations
2022
Abstract:Key personnel and their competences play important roles in continuity management and improving resilience of cybersecurity in organizations. Researchers have addressed many topics and studies in the cybersecurity domain. However, relevant cybersecurity skills and acquisition of them in expertise development, have only been partially touched. If designed systematically and properly, cybersecurity training can improve cybersecurity expertise to ensure better performance in complex cybersecurity situations. More through study on the acquisition of cybersecurity skills, and work-life needs are needed. The research three questions of this study are: How do work-life representatives see…
Resistant ammonia-oxidizing archaea endure, but adapting ammonia-oxidizing bacteria thrive in boreal lake sediments receiving nutrient-rich effluents
2018
Climate change along with anthropogenic activities changes biogeochemical conditions in lake ecosystems, modifying the sediment microbial communities. Wastewater effluents introduce nutrients and organic material but also novel microbes to lake ecosystems, simulating forthcoming increases in catchment loadings. In this work, we first used 16s rRNA gene sequencing to study how the overall sediment microbial community responds to wastewater in six boreal lakes. To examine forthcoming changes in the lake biogeochemistry, we focused on the ammonia-oxidizing archaea (AOA) and bacteria (AOB), and examined their functional and compositional community response to wastewater. Although we found the l…
Electrical Safety Analysis in the Presence of Resonant Grounding Neutral
2019
The resonant grounding is one of the possible methods of the system neutral grounding for the medium voltage distribution. IEEE standards do define this grounding configuration, but important advantages and drawbacks of the resonant grounding might not be fully known, due to its rather uncommon application in North America. On the other hand, resonant grounding in Europe is imposed by the increased requirements for power quality, especially for medium-voltage (MV) industrial users, imposed to electric utilities by regulatory authorities, with the purpose to protect the interests of users and consumers. Level of the continuity of the service, magnitude and phase of ground-fault currents, mag…
Lo spazio pubblico adattivo: esplorare la transizione digitale per il benessere sociale e ambientale
2022
The present social and environmental challenges, the impact of climate change and the pandemic, revealed the urgency and the opportunity to rethink urban design through its renewed spaces and temporalities. The pandemic offered a ‘natural experiment’ to explore and develop new perspectives, making public spaces more resilient. Contributing towards a rethink of these spaces, the present paper explores adaptive architecture with responsive technologies and their capability of shaping public spaces to constitute a conversation piece with the surrounding environment. This approach combines and reflects different disciplinary fields: architecture, civic interaction and urban design. The explorat…
Restoration of a XVII Century’s predella reliquary: From Physico-Chemical Characterization to the Conservation Process
2021
We report on the restoration of a XVII century’s predella reliquary, which is a part of a larger setup that includes a wall reliquary and a wooden crucified Christ, both belonging to the church of “Madre Maria SS. Assunta”, in Polizzi Generosa, Sicily, Italy. The historical/artistic and paleographic research was flanked successfully by the scientific objective characterization of the materials. The scientific approach was relevant in the definition of the steps for the restoration of the artefact. The optical microscopy was used for the identification of the wood species. Electron microscopy and elemental mapping by energy-dispersive X-ray (EDX) was successful in the identification of the l…
El efecto moderador de la edad en la relación entre el valor percibido, las TIC del minorista y la lealtad del cliente
2010
AbstractInformation and communication technology (ICT) may represent a source of benefits for retailers. However, there is a debate in the literature on how ICT influences customer-supplier relationships. In addition, the evidence on the effect of age on consumer attitudes towards retail technological solutions is not conclusive. This paper proposes and tests a model to analyze the influence of retail ICT on consumer loyalty towards the retailer, as well as to assess the moderating role of consumer age on this relationship. As a result, customer assessment of retail ICT, together with perceived value, exerts a positive influence on consumer commitment and satisfaction, being the latter an a…
The Moderating Effect of Store Format on the Relationships Between ICT, Innovation and Sustainability in Retailing
2021
Innovation and sustainability are postulated as key variables for the future of large commercial distribution. In addition, the development of Information and Communication Technologies (ICT) solutions, and especially those related to Artificial Intelligence (i.e., Just Walk Out, Intelligent Retail Lab) and digitization, are particularly relevant factors in the current pandemic scenario in which retail companies operate. These tools are essential to face the derived changes in commercial relations, especially between companies and consumers. For all these reasons, this work aims to examine the effect of ICT, as a driving factor for innovation and its direct and indirect impact on sustainabi…
A Systematic Literature Review and Analysis of Mobile Retailing Adoption
2019
The purpose of this study is to provide a comprehensive updated review and analysis of mobile retailing adoption. Although research on mobile channel utilization has increased significantly in recent years and many new studies on this topic have been published, research has not yet provided a clear structure regarding how consumers’ expectations have advanced in relation to mobile retailing adoption. Thus, this study synthetizes the mobile retail adoption literature and develops a framework for it. Our systematic literature review analyzed 94 scientific articles that were published between 2010 and 2018 to determine customers’ different expectations and demands during different mobile chann…
Lovastatin inhibits Rho-regulated expression of E-selectin by TNFalpha and attenuates tumor cell adhesion.
2003
E-selectin mediated cell-cell adhesion plays an important role in inflammatory processes and extravasation of tumor cells. Tumor necrosis factor-alpha (TNF-alpha) induces E-selectin gene and protein expression in primary human endothelial cells (HUVEC) and in an endothelial cell line (EA.hy-926). As shown by ELISA and FACS analyses, HMG-CoA reductase inhibitors (e.g., lovastatin) impair the TNF-alpha stimulated increase in E-selectin protein expression. Similar results were obtained for E-selectin mRNA expression and promoter activity, indicating that the effect of lovastatin is based on inhibition of gene expression. The effective inhibitory concentration of lovastatin was in a physiologic…
Educate to coexist with the flood risk
2020
In the Mediterranean region, floods are the main natural risk. This hazard has been aggravated in recent decades by the increase in exposure of the human being and is expected to increase the danger according to the forecast of climate change scenarios. For this reason, dealing with these issues in the classroom and the training of teachers on this subject should be a priority, as established in the curriculum of Primary Education (Social Sciences). The objectives of this research are: 1) To analyze the knowledge that future teachers have about the risk of flooding to develop these contents in the classroom; 2) Check the relevance that they give to this social-environmental problem; and 3) …
