The effects of ontology-based and password-protected blog access control on perceived privacy benefit and perceived ease of use

Abstract

Purpose -This work empirically evaluates the effectiveness of the novel ontology-based access-control mechanism and the common password-protected access-control mechanism for social blogs. The paper aims to discuss these issues. Design/methodology/approach -The ontology-based access-control scheme is designed to fit two characteristics of blog activities: social relationships and tags. A laboratory experiment is conducted to assess the perceived privacy benefit and perceived ease of use of the two mechanisms. Findings -Analytical results indicate that, with the ontology-based access-control scheme, users perceive more privacy benefit than with the password-protected access-control scheme. The perceived ease of use with the ontology-based and password-protected access-control systems did not differ significantly.Research limitations/implications -Cross-boundary collaborations need an appropriate approach to control communication access. Further study is required to evaluate the ontology-based access-control scheme applied in cross-organizational and cross-departmental collaborations. Practical implications -From a knowledge management perspective, blogs can store personal and organizational knowledge and experiences. The ontology-based access-control scheme encourages knowledge sharing for appropriate persons. Originality/value -The new ontology-based access-control mechanism can help online users keep secrets from selected people to gain more privacy benefits than the existing password-protected access-control mechanism.

Airport passengers' adoption behaviour towards self-check-in Kiosk Services: the roles of perceived ease of use, perceived usefulness and need for human interaction

“…This result is in line with previous studies findings. The SST services, especially the self-check-in kiosk and bag drop kiosk, helps passenger free from extra effort during the check-in and bag drop process, and it enhances their trip experience (Amin et al., 2014; Liu, 2014; Nasser Al-Suqri, 2014; Chen et al., 2014). To add, Kashik et al.…”

Removal of Arsenic from Aqueous Solution by Chemical Modification of Date Palm Bark

“…The effect of pH on Arsenic adsorption by the mercerized Bark based adsorbent (MBA) was examined at a pH range of 2.0 to 9.0 at an adsorbent dose of 0.1mg/100. The pH affects DP Bark adsorption because the formation of anions as well as the surface charges on the adsorbent [26]. Arsenic removal efficiencies were observed to be 97, 96.4, 95, 90, 80, 78, 74, and 70 % at pH values of 2, 3, 4, 5, 6, 7, 8 and 9 respectively.…”

Analysis of influencing factors of online community knowledge-sharing from the perspective of the platform environment

“…Globally, scholars have conducted extensive research on the influencing factors of knowledge-sharing (Han et al. , 2019; Liu, 2014; Sheng and Hartono, 2015; Wu et al. , 2019), but these studies were generally based on the perspective of “users” and rarely considered the impact of knowledge-sharing from the view of the platform environment.…”

“…Determining the influencing factors that motivate users to share their knowledge in the online community might help to enhance their enthusiasm for participation. Globally, scholars have conducted extensive research on the influencing factors of knowledge-sharing (Han et al, 2019;Liu, 2014;Sheng and Hartono, 2015;Wu et al, 2019), but these studies were generally based on the perspective of "users" and rarely considered the impact of knowledge-sharing from the view of the platform environment. However, social cognitive theory, ecosystem theory, and dialectical materialism all emphasize the influence of the environment on individual behavior to varying degrees.…”
