Agents of responsibility in software vulnerability processes     

Ari Takanen  Petri Vuorijärvi  Marko Laakso  Juha Röning 《Ethics and Information Technology》2004,6(2):93-110

Modern software is infested with flaws having information security aspects. Pervasive computing has made us and our society vulnerable. However, software developers do not fully comprehend what is at stake when faulty software is produced and flaws causing security vulnerabilites are discovered. To address this problem, the main actors involved with software vulnerability processes and the relevant roles inside these groups are identified. This categorisation is illustrated through a fictional case study, which is scrutinised in the light of ethical codes of professional software engineers and common principles of responsibility attribution. The focus of our analysis is on the acute handling of discovered vulnerabilities in software, including reporting, correcting and disclosing these vulnerabilities. We recognise a need for guidelines and mechanisms to facilitate further improvement in resolving processes leading to and in handling software vulnerabilities. In the spirit of disclosive ethics we call for further studies of the complex issues involved.  相似文献

Pre-service teachers’ acceptance of mobile-technology-supported learning activities     

Islamoglu  Hakan  Kabakci Yurdakul  Isil  Ursavas  Omer Faruk 《Educational technology research and development : ETR & D》2021,69(2):1025-1054

The purpose of this study was to develop a mobile learning acceptance model for pre-service teachers and to examine the relationships among technology acceptance factors. The literature on mobile learning acceptance lacks studies on pre-service teachers and studies that include concrete mobile learning scenarios. To overcome these problems, we have developed and implemented a mobile-technology-enabled information technology course. The data collection and analysis were conducted in two separate studies. First, we developed a mobile learning acceptance scale and applied confirmatory factor analysis with 408 participants. The final instrument included 28 items measuring eight technology acceptance factors, namely behavioral intention, attitude towards use, perceived usefulness, perceived ease of use, social influence, facilitating conditions, self-efficacy, and anxiety. After this, we collected a new set of data from 316 participants to examine the relationships among the factors using structural equation modeling. In both studies, we investigated the respective models’ invariance across gender and discipline groups, and both models fulfilled invariance requirements. The results indicated that perceived ease of use and social influence have direct effects on behavioral intention, whereas self-efficacy has an indirect effect. Depending on the group, the explained variance of behavioral intention ranged between 18.1% and 60.6%.

Using Slack for computer-mediated communication to support higher education students’ peer interactions during Master’s thesis seminar     

Ari Tuhkala  Tommi Kärkkäinen 《Education and Information Technologies》2018,23(6):2379-2397

Our study contributes to the research on computer-mediated communication in higher education by experimenting a modern communication tool called Slack. In particular, we consider using Slack to support students’ peer interactions during Master’s thesis work. For this purpose, we designed a case study that was executed in a Master’s thesis seminar course. During the course, all out-of-class communication was carried out by using Slack, instead of e-mails or learning management systems. After the course, we used a questionnaire to investigate how the students perceived Slack for asking for assistance, their intention to use Slack, and Slack’s ease of use. Furthermore, the questionnaire asked feedback about challenges that the students found in slack. To examine the students’ peer support in Slack, we analysed the messages in the course’s public discussion channels. We investigated opportunities and challenges of Slack from instructional perspective by conducting an auto-ethnographic data collection. Our analysis revealed that the students perceived Slack as an easy-to-use communication tool with a low threshold of asking questions. The students also expressed high intentions to use Slack in the future. However, the students were worried of information overload in Slack, frustrated with decentralisation of communication tools in higher education, and cautious of using communication tools that are not officially supported by the university. The students’ interactions were assigned to three categories: practical, technical, and thesis-related. Analysis of these categories revealed that the students were able to explicate and solve issues in Slack, but the issues were only related to practical and technical problems, instead of actual Master’s thesis writing. The teacher perceived that Slack enhanced bi-directional communication with the students, but faced issues related to file management and user authentication. The results implicate that developing an alternative for Slack from educational premises could be more useful than a product that is not originally developed for pedagogical needs. Finally, we present recommendations that help educators to use Slack in their educational practices.  相似文献   

Word Recognition Processes in College-Age Students’ Reading Comprehension Achievement     

Omer Ari 《Community College Journal of Research & Practice》2016,40(8):718-723

This paper presents a brief review of the previous research on word recognition skills of college-age adults. Unlike the general understanding in the reading field of diminished effects for word reading skills at the higher grades, findings show word reading processes continue to determine reading comprehension success in college-age adults. Instructional implications, based on the review of literacy interventions, are presented in favor of fluency-based activities designed to encourage careful processing of texts with familiar topics and language in the service of building strongly-amalgamated lexical representations.  相似文献   

Comparison of maximal anaerobic running tests on a treadmill and track   总被引：1，自引：0，他引：1  

Nummela A  Hämäläinen I  Rusko H 《Journal of sports sciences》2007,25(1):87-96

To develop a track version of the maximal anaerobic running test, 10 sprint runners and 12 distance runners performed the test on a treadmill and on a track. The treadmill test consisted of incremental 20-s runs with a 100-s recovery between the runs. On the track, 20-s runs were replaced by 150-m runs. To determine the blood lactate versus running velocity curve, fingertip blood samples were taken for analysis of blood lactate concentration at rest and after each run. For both the treadmill and track protocols, maximal running velocity (v max), the velocities associated with blood lactate concentrations of 10 mmol x l-1 (v10 mM) and 5 mmol x l(-1) (v5 mM), and the peak blood lactate concentration were determined. The results of both protocols were compared with the seasonal best 400-m runs for the sprint runners and seasonal best 1000-m time-trials for the distance runners. Maximal running velocity was significantly higher on the track (7.57 +/- 0.79 m x s(-1)) than on the treadmill (7.13 +/- 0.75 m x s(-1)), and sprint runners had significantly higher vmax, v10 mM, and peak blood lactate concentration than distance runners (P < 0.05). The Pearson product--moment correlation coefficients between the variables for the track and treadmill protocols were 0.96 (v max), 0.82 (v10 mM), 0.70 (v5 mM), and 0.78 (peak blood lactate concentration) (P < 0.05). In sprint runners, the velocity of the seasonal best 400-m run correlated positively with vmax in the treadmill (r = 0.90, P < 0.001) and track protocols (r = 0.92, P < 0.001). In distance runners, a positive correlation was observed between the velocity of the 1000-m time-trial and vmax in the treadmill (r = 0.70, P < 0.01) and track protocols (r = 0.63, P < 0.05). It is apparent that the results from the track protocol are related to, and in agreement with, the results of the treadmill protocol. In conclusion, the track version of the maximal anaerobic running test is a valid means of measuring different determinants of sprint running performance.  相似文献   

Applications,MATLAB and linear algebra as a unifying vehicle for the engineering-oriented syllabus     

Ari Naimark 《European Journal of Engineering Education》2002,27(4):409-424

The paper considers the negative effects of the degeneration of the mathematics syllabus for engineering-oriented students into a collection of unconnected recipes, and presents a modernization of a linear algebra course to serve as a tool for the unification of the syllabus into a single transparent picture. The modernization is centred on the use of operator language as enabled by the incorporation of MATLAB-based applications into the theoretical part of the course.  相似文献   

Exploring the disclosure of child sexual abuse with alleged victims and their parents     

Hershkowitz I  Lanes O  Lamb ME 《Child abuse & neglect》2007,31(2):111-123

OBJECTIVE: The goal of the present study was to examine how children disclosed sexual abuse by alleged perpetrators who were not family members. METHODOLOGY: Thirty alleged victims of sexual abuse and their parents were interviewed. The children were interviewed using the NICHD Investigative Interview Protocol by six experienced youth investigators. The same principles were followed when the parents were asked to describe in detail what had happened since the abusive incidents. The statements made by the children and parents were then content analyzed. Major characteristics of the children's and parents' reported behaviors were identified by two independent raters. FINDINGS: More than half (53%) of the children delayed disclosure for between 1 week and 2 years, fewer than half first disclosed to their parents, and over 40% did not disclose spontaneously but did so only after they were prompted; 50% of the children reported feeling afraid or ashamed of their parents' responses, and their parents indeed tended to blame the children or act angrily. The disclosure process varied depending on the children's ages, the severity and frequency of abuse, the parents' expected reactions, the suspects' identities, and the strategies they had used to foster secrecy. CONCLUSIONS: The children's willingness to disclose abuse to their parents promptly and spontaneously decreased when they expected negative reactions, especially when the abuse was more serious. A strong correlation between predicted and actual parental reactions suggested that the children anticipated their parents' likely reactions very well.  相似文献   

Measuring college students' reading comprehension ability using cloze tests     

Rihana Shiri Williams  Omer Ari  Carmen Nicole Santamaria 《Journal of Research in Reading》2011,34(2):215-231

Recent investigations challenge the construct validity of sustained silent reading tests. Performance of two groups of post‐secondary students (e.g. struggling and non‐struggling) on a sustained silent reading test and two types of cloze test (i.e. maze and open‐ended) was compared in order to identify the test format that contributes greater variance in reading comprehension. One hundred participants were recruited from students enrolled in a preparatory course for a high‐stakes statewide reading examination. Our results suggest that all three measures have good concurrent validity. There was no evidence that open‐ended cloze performance was more related to verbal ability than any other reading measure. Maze performance did the best job at discriminating between our struggling and non‐struggling readers. Implications for reading comprehension assessment in post secondary‐aged adults are discussed.  相似文献
