ABSTRACTThis study examines how college students perceive social media as a mean for learning and teaching and whether its use is associated with different variables that reflect both student and t...
Influenza vaccination: opinions of health care professionals working in pediatric emergency departments
2018
Abstract Background Vaccine coverage of health care professionals against influenza is still low in Italy, as well as in other European countries. Methods Between March and May 2018, this study was performed to collect the opinions of Pediatric health care professionals, working in emergency departments, regarding the efficacy and safety of the influenza vaccine. An anonymous online survey was employed to evaluate socio-demographic and professional characteristics, knowledges, beliefs and attitudes. Results Five hundred four health care professionals completed the survey: 331 physicians, 140 nurses and 33 other health are professionals. During the 2017–18 season, 55.8% of physicians, 19.3% …
Zeroing in on the Effect of the Schizophrenia Label on Stigmatizing Attitudes: A Large-scale Study.
2017
The idea that psychiatric diagnoses are not mere descriptors of a symptomatology but create incrementally negative effects in patients has received considerable support in the literature. The flipside to this effect, that calling someone by a psychiatric diagnosis also has an effect on how this person is perceived by others, however, has been less well documented and remains disputed. An experimental study was conducted with a large sample (N = 2265) to ensure statistical power to detect even small effects of such adding a psychiatric diagnosis to a description of symptoms or not. Dependent variables were chosen in an exploratory manner and tests were corrected for alpha inflation. Results …
Inhibitoren der Korrosion 24 (1) - Zur Vergleichbarkeit der Abhängigkeit der Korrosion und Korrosionsinhibierung von der Chloridionen- und Inhibitork…
1979
Die Abhangigkeit der „unter Standardbedingungen” im Schuttelversuch ohne und mit Inhibitoren ermittelten O2-Aufnahmegeschwindigkeit von der Chloridionenkonzentration und der Menge an Eisenpulver wird ermittelt. Ergebnis: die von uns bisher eingehaltenen Standardbedingungen vermitteln an Hand der Schutz werte ein qualitativ verlasliches Bild uber die Inhibitorwirksamkeit. Die Vergleichbarkeit der im Schuttelversuch mit DAB 6-Eisenpulver ermittelten Werte mit den im Schuttelversuch mit 1405-Stahlblechen gefundenen Werten wird durch Versuche mit 1405-Stahlblechraspel abgesichert. Die Korrosionsrate phosphatisierter Stahlbleche 1405 wird durch Inhibitoren mit Phosphonsauregruppen wirksam unterd…
Location of navigation menus in websites: an experimental study with Arabic users
2015
Published online: 31 October 2015 While Arabic users represent by far the fastest growing language population on the Internet, research about how the peculiarities of Arabic language may shape users’ web interactions is still scarce. The preferences of Arabic users for menu location in websites have been studied. Two competing arguments have been proposed regarding the best location of menus in websites: conventional design (navigation menu should be placed on that side where users expect it based on previous experience) and reading direction (navigation menu should be placed on that side where readers are used to start off reading, so that the navigation menu is likely to be attended first…
A Cognitive Model of Trust for Biological and Artificial Humanoid Robots
2018
This paper presents a model of trust for biological and artificial humanoid robots and agents as antecedent condition of interaction. We discuss the cognitive engines of social perception that accounts for the units on which agents operate and the rules they follow when they bestow trust and assess trustworthiness. We propose that this structural information is the domain of the model. The model represents it in terms of modular cognitive structures connected by a parallel architecture. Finally we give a preliminary formalization of the model in the mathematical framework of the I/O automata for future computational and human-humanoid application.
Contribution to variational analysis : stability of tangent and normal cones and convexity of Chebyshev sets
2014
The aim of this thesis is to study the following three problems: 1) We are concerned with the behavior of normal cones and subdifferentials with respect to two types of convergence of sets and functions: Mosco and Attouch-Wets convergences. Our analysis is devoted to proximal, Fréchet, and Mordukhovich limiting normal cones and subdifferentials. The results obtained can be seen as extensions of Attouch theorem to the context of non-convex functions on locally uniformly convex Banach space. 2) For a given bornology β on a Banach space X we are interested in the validity of the following "lim inf" formula (…).Here Tβ(C; x) and Tc(C; x) denote the β-tangent cone and the Clarke tangent cone to …
Do microfinance rating assessments make sense? An analysis of the drivers of the MFI ratings
2011
Rating assessments of microfinance institutions are claimed to measure a combination of creditworthiness, trustworthiness and excellence in microfinance. Using a global dataset covering reports from 324 microfinance institutions, this study suggests that these ratings are mainly driven by size, profitability, and risk. The ratings do not seem to capture the double bottom-line objective of microfinance institutions, as our analyses are unable to prove any statistical relationship between microfinance ratings and the social objectives of these institutions. Moreover, the association between operational efficiency and microfinance ratings appears weak. Although there are some minor differences…
Trust-aware RBAC
2012
Published version of a chapter in the book: Computer Network Security. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-33704-8_9 In this paper we propose a trust-aware enhancement of RBAC (TA-RBAC) that takes trustworthiness of users into consideration explicitly before granting access. We assume that each role in the framework is associated with an expression that describe trustworthiness of subjects required to be able to activate the role, and each subject (user) has assigned trustworthiness level in the system. By adding trustworthiness constraints to roles we enhance system, for example, with more flexible ability to delegate roles, to control reading/updating…
Stakeholder perceptions of alternative food entrepreneurs
2009
This paper focuses on rural entrepreneurs' perceptions of their stakeholders with respect to their influence towards the economic success of farms and environmental issues, as well as their trustworthiness. There is special emphasis on the comparison of perceptions between suppliers of alternative food supply chains and suppliers of conventional supply chains. Survey research, with a final sample size of 522 rural entrepreneurs in Central Finland, was used as a research method. The results showed that 28% of the respondents could be defined as alternative food entrepreneurs. Significant differences between alternative and conventional food entrepreneurs were related to perceptions towards c…
