How Are Concerns About Errors And Ethics Related To Demands For Information Systems Audits?, Joseph S. Mollick Ph. D Oct 2015

How Are Concerns About Errors And Ethics Related To Demands For Information Systems Audits?, Joseph S. Mollick Ph. D

Communications of the IIMA

What factors affect individuals' demands that information systems (IS) audits are implemented in the organizations with which they do business? Using concepts and constructs from theoretical literature on individuals’ concerns about organizational information management practices, we build a theoretical model that can explain and predict individuals' demand for information systems audit in organizations. Using data from U. S. university students, we empirically test two hypotheses using a multiple regression model. It was found that students’ concern about error in data and their concern about organizational ethics of information management positively affect students’ demand for IS audit at U. S. universities.


The Effects Of Text Complexity On Online Review Helpfulness, Michael J. Hine Oct 2015

The Effects Of Text Complexity On Online Review Helpfulness, Michael J. Hine

Communications of the IIMA

This research reported in this paper extends the literature on the helpfulness of online reviews. Previous research has assessed online reviews using standard unidimensional readability algorithms. This research extends previous work by investigating a multidimensional framework, and associated measures, of text complexity and its impact on the helpfulness of online reviews. Results show that as the amount of passive voice and negation in online reviews increase, the helpfulness of said review decreases. Other significant predictors of review helpfulness include word meaningfulness, lexical diversity, and the number of modifiers per noun phrase.


It Certification: Demand, Characteristics And Integration Into Traditional University Mis Curriculum, Mohammad A. Rob Oct 2015

It Certification: Demand, Characteristics And Integration Into Traditional University Mis Curriculum, Mohammad A. Rob

Communications of the IIMA

The value of IT certification is a subject of debate. IT magazines suggest that certifications can provide opportunities for new positions, promotions or salary increases to existing employees. Research suggests that IT certification can boost a fresh graduate’s profile to garner the attention of a hiring manager. Research also suggests that certification, education and experience are complimentary factors in the future job prospects of a candidate. For years, educators have been suggesting to include IT certifications in the traditional computing curricula of colleges and universities. However, due to a dearth of knowledge and commitment, faculty members have been reluctant to …


Consumer-To-Consumer Ecommerce: Acceptance And Intended Behavior, Lori N. K. Leonard, Kiku Jones Oct 2015

Consumer-To-Consumer Ecommerce: Acceptance And Intended Behavior, Lori N. K. Leonard, Kiku Jones

Communications of the IIMA

Consumer-to-consumer ecommerce is used by individuals who come together to buy and sell products. With the widespread use of this commerce environment comes the need to explore potential influences on its acceptance or one’s intention to use it. Using the technology acceptance model, the theory of planned behavior, and ecommerce success theory, a research model is proposed. After collecting 94 survey responses, the model is examined using regression analysis. The findings indicate that perceived usefulness, perceived ease of use, attitude, and satisfaction influence one’s acceptance of or intention to use consumer-to-consumer ecommerce. A discussion of the study findings is provided.

A Semantic Network For Modeling Biological Knowledge In Multiple Databases, Jeffrey Stone, Xindong Wu, Marc Greenblatt Feb 2015

A Semantic Network For Modeling Biological Knowledge In Multiple Databases, Jeffrey Stone, Xindong Wu, Marc Greenblatt

Communications of the IIMA

We have developed a semantic network of biological terminology to aid in the retrieval and integration of biological information from a variety of disparate information sources. Our semantic network strives to provide a categorization of biological concepts and relationships among these concepts. The semantic network will impart a knowledge structure through which computers can "reason " and draw conclusions about biological data objects and will provide a federated view of the many disparate databases of interest to biologists. In the development of our system, we have included the concepts from several established controlled vocabularies, chief among them being the National …

Semi-Automatic Query Expansion Approach To Web- Based Information Retrieval, Chaoyang Zhang, Kuo Lane Chen, Huei Lee, Hong Lan, Qijun Chen, Jiangyan He

Communications of the IIMA

The query used for Web searching is usually short and may not be able to reflect the intrinsic semantics of the user information need. The purpose of the paper is to take into account user information feedback, and to develop a semi-automatic query expansion approach to improve the effectiveness of Web searching. A search engine has been developed using the vector information retrieval model to validate the semi-automatic query expansion approach. The experiments show that this approach may improve the effectiveness of web searching.

Utilizing Mobile Phones For Payment, Ook Lee, Woonghee Lee

Communications of the IIMA

This study introduces a sound-based mobile payment system. Using a mobile phone for payment for mobile commerce is essential for its success. The proposed system will use sound that is generated from the existing mobile phone and the sound can be recognized by the existing credit card reader of the shop with an installation of an ordinary microphone and simple software to process sound input. This system is a better system since it doesn't require customers to buy a new mobile phone and the cost for the microphone and the software is very low.

An Analysis Of Electronic Meeting Comment Translation, Mmilam Aiken, Jose Ablanedo, Mahesh B. Vanjani

Communications of the IIMA

Multilingual groups often find communication difficult. Even with human interpreters, these groups still suffer from the inherent limitations of oral meetings: only one person at a time can talk, comments are not anonymous, and ideas must be recorded manually. Group Support Systems (GSS) have been used to increase the productivity of traditional, oral meetings by allowing participants to exchange automatically recorded, typed comments simultaneously and anonymously. Integration of language translation software with these systems could enable multilingual groups to achieve the same benefits obtained by monolingual groups. This paper investigates the feasibility of using automatic language translation in GSS meetings …

The Next Generation Of Mobile Computing For Hospitals, Warren Adis

Communications of the IIMA

Mobile computing in the broadest sense is when multiple communications devices work together within an environment, unhampered by equipment limitations, distance, or interference. As computer and networking devices are put into smaller and smaller envelopes, their workplace usefulness increases. These mobile devices offer the potential of increasing the quality of healthcare services by making better use of hospital resources, including improved communications among medical and support staff, and increased patient monitoring. This paper depicts several hospital scenarios in order to conceptualize the planning and design of future mobile networks, taking into consideration patient care, management thinking, and technical issues.

Modular Curriculum Design Using Personal Learning Plans And Reusable Learning Components, Jay M. Lightfoot Jan 2015

Modular Curriculum Design Using Personal Learning Plans And Reusable Learning Components, Jay M. Lightfoot

Communications of the IIMA

University-based education is facing direct competition from for-profit corporations over the lucrative lifetime-learning market. This is occurring primarily because universities have not adapted to advances in technology and changes in the educational needs of students. To correct this problem, a new curriculum solution is proposed. This solution is loosely based upon the model curricula generated by professional organizations. The solution utilizes personal learning plans tied to a global learning schema. The end result is a very flexible curriculum delivery model that effectively utilizes modern technology and is potentially superior to any offered by commercial education providers.
