Moral sensitivity in information security dilemmas

2019

Activities that undermine information security such as noncompliance with information security policies raise moral concerns since they can expose valuable information assets. Existing research shows that moral reflection could play an inhibitory role in one’s decision to undermine information security. However, it is not clear whether users interpret such decisions from a moral standpoint to engage in moral reflection in the first place. Users have to be morally sensitive before they engage in moral reflection. Moral sensitivity involves perceiving a situation as morally relevant, identifying the parties involved and perceiving possible courses of action. We examine moral sensitivity in se…

Investigating the Impact of Organizational Culture on Information Security Policy Compliance : The Case of Ethiopia

2021

Information security is one of the organizations' top agendas worldwide. Similarly, there is a growing trend in the kinds and rate of security breaches. Information security experts and scholars concentrate on outsiders' threats; conversely, insiders are responsible for most of the security breaches in organizations. Further, the majority of information security research findings are limited to solutions that are technically focused. However, it is now recognized that the technological approach alone does not carry the security level needed. So this led researchers to embark on socio-technical approaches. Thus, this study explores organizational culture's effect on employees' intention to c…

Euroopan unionin yleisen tietosuoja-asetuksen aiheuttamat muutokset organisaatioiden tietoturvapolitiikkoihin

2017

EU:n yleistä tietosuoja-asetusta aletaan soveltaa toukokuun 25. päivänä 2018 ja sen aiheuttamat muutokset ovat merkittäviä ja kunnianhimoisia. Se on yksi laaja-alaisimpia EU:n lakimuutoksia viimevuosien ajalta. Yleisen tietosuoja-asetuksen vaikutukset ovat merkittäviä organisaatioille, sillä epäonnistuessaan asetuksen vaatimusten noudattamisessa organisaatio joutuu maksamaan merkittävät sakot, korkeimmillaan joko 4% yrityksen globaalista vuosittaisesta liikevaihdosta tai 20 000 000 euroa riippuen siitä, kumpi on korkeampi. Yleinen tietosuoja-asetus tulee luultavasti vaikuttamaan tietoturvapoliitikkojen kehitykseen, kun yritykset pyrkivät noudattamaan uusia vaatimuksia. Tietotu…

Measuring users' level of information security awareness : research and development of sample questions

2017

Tämän gradun tarkoituksena on käsiteanalyysin avulla hahmottaa tärkeimpiä omaisuuksia tietoturvatietoisuudesta ja tavoista levittää sitä, tutustua niihin tarkemmin, ja muodostaa näistä perusteltuja ja käyttäjille olennaisia kysymyksiä joilla selvittää käyttäjän tietoturvatietoisuutta. Aiheen tarkempi läpikäynti on tärkeää, sillä aiemmissa tutkimuksissa on havaittu, että käyttäjät kertovat noudattavansa tietoturvapolitiikoita, vaikka tarkemmin tutkittaessa eivät tienneet tai ymmärtäneet tietoturvapolitiikoiden sisältöä. Kysymysten muodostamisessa otetaan huomioon myös muita käsiteanalyysi vaiheessa selvinneitä piirteitä, joilla tehdä kysymyksistä parempia. Tuloksena esitetään 20 esimerkkikys…

A novel and inexpensive method for measuring volcanic plume water fluxes at high temporal resolution

2017

© 2017 by the authors.Water vapour (H2O) is the dominant species in volcanic gas plumes. Therefore,measurements of H2O fluxes could provide valuable constraints on subsurface degassing and magmatic processes. However, due to the large and variable concentration of this species in the background atmosphere, little attention has been devoted to monitoring the emission rates of this species from volcanoes. Instead, the focus has been placed on remote measurements of SO2, which is present in far lower abundances in plumes, and therefore provides poorer single flux proxies for overall degassing conditions. Here, we present a new technique for the measurement of H2O emissions at degassing volcano…

Cathodoluminescence and photoluminescence study of trap centers in amorphous silicon oxynitride

2002

Amorphous silicon oxynitride (a-SiO/sub x/N/sub y/) films with different compositions were prepared using low-pressure chemical vapor deposition (LPCVD) technique, The cathodoluminescence and photoluminescence of this samples were measured from the red band to the ultraviolet band to study the trap centers in silicon oxynitride. A 1.8-1.9 eV band was found and is attributed to the oxygen and nitrogen atoms with unpaired electrons whereas the 2.7 eV band is attributed to two-fold coordinated silicon atoms with two electrons. The 5.4 eV shoulder is due to the peroxy radicals and other ultraviolet bands are supposed to due due to the Si-Si bonds.

Anomalous and normal Hall effect in hydrogenated amorphous Si prepared by plasma enhanced chemical vapor deposition

2010

The double sign anomaly of the Hall coefficient has been studied in p -doped and n -doped hydrogenated amorphous silicon grown by plasma enhanced chemical vapor deposition and annealed up to 500 °C. Dark conductivity as a function of temperature has been measured, pointing out a conduction mechanism mostly through the extended states. Anomalous Hall effect has been observed only in the as-deposited n -doped film, disappearing after annealing at 500 °C, while p -doped samples exhibit normal Hall effect. When Hall anomaly is present, a larger optical band gap and a greater Raman peak associated with Si-H bond are measured in comparison with the cases of normal Hall effect. The Hall anomaly wi…

Characterization of high-temperature performance of cesium vapor cells with anti-relaxation coating

2017

© 2017 Author(s). Vapor cells with antirelaxation coating are widely used in modern atomic physics experiments due to the coating's ability to maintain the atoms' spin polarization during wall collisions. We characterize the performance of vapor cells with different coating materials by measuring longitudinal spin relaxation and vapor density at temperatures up to 95 °C. We infer that the spin-projection-noise-limited sensitivity for atomic magnetometers with such cells improves with temperature, which demonstrates the potential of antirelaxation coated cells in applications of future high-sensitivity magnetometers.

Monolayer graphene doping and strain dynamics induced by thermal treatments in controlled atmosphere

2018

Time dynamics of doping and strain induced in single layer graphene by thermal treatments up to 300 degrees C in vacuum, nitrogen, carbon dioxide and oxygen controlled atmosphere are deeply studied by Raman spectroscopy and they are compared with its morphological evolution investigated by Atomic Force Microscopy. The reaction dynamics in oxygen treatments is determined down to a time scale of few minutes as well as that of dedoping process made by water vapor treatment. The interplay of strain modification and doping effects is separated. The strain is clarified to be strongly influenced by the cooling time. The doping removal is dominated by the water vapor, showing that the concentration…
