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

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

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.

Using A Work System Metamodel And Usdl To Build A Bridge Between Business Service Systems And Service Computing, Steven Alter, Alistair Barros

Business Analytics and Information Systems

This paper explores the support for more comprehensive modeling of service systems than that possible through modeling methods developed through partial perspectives, with uncertainties about their wider suitability and need for integration with other methods in this domain. It responds to a Dual Call for Papers from INFORMS Service Science and IEEE Transactions on Service Computing requesting contributions that address the barely explored challenge of establishing links between business views of service systems and more technical views from service computing. Competing definitions of service reveal that most business views of service emphasize acts or outcomes produced for others, whereas a …

Endogenous Network Effects, Platform Pricing And Market Liquidity, Mei Lin, Ruhai Wu, Wen Zhou

Research Collection School Of Computing and Information Systems

This paper examines a monopoly platform's two-sided pricing strategies in a setting with seller competition, which gives rise to not only positive cross-side network effects between buyers and sellers, but also a negative same-side network effect among sellers. We show that platform pricing depends crucially on the characteristics associated with market liquidity, which contrasts with the previous studies that point to the two sides' relative demand elasticities and/or network effects. A market is said to be more liquid when it has less friction, resulting in a larger total surplus for the platform economy and hence greater equilibrium entry on both …

Managing Challenges Of Multicultural Information Systems Project Teams In South Africa, Udo Richard Averweg, Tom Addison

The African Journal of Information Systems

Information Systems (IS) project teams in South Africa need to be led by individuals whose skills include managing cultural diversity. A three phase Delphi study was used to collect and rank the methods used to manage culturally diverse IS project teams in the Johannesburg area of South Africa. The ‘top’ fifteen methods were selected and are presented in the report. The leading method found was to appoint project managers or team leaders who are aware of diversity issues, followed by the placing of increased emphasis on goals, objectives, boundaries and tasks. The paper’s principal contribution is that the study is …

Investigating South African Vendors’ Cloud Computing Value Proposition To Small, Medium And Micro Enterprises: A Case Of The City Of Tshwane Metropolitan Municipality, Lucas N. Gumbi, Ernest Mnkandla

The African Journal of Information Systems

While Small, Medium and Micro Enterprises (SMMEs) are known to contribute significantly to economic growth and reduction of unemployment worldwide, South Africa experiences high failure rate, stagnation and limited growth of SMMEs. Cloud computing, which promises cost efficiencies for SMMEs through its unique outsourcing based business model, is emerging as a viable solution and an excellent value proposition to SMMEs. This study investigated the value proposition of cloud computing vendors to South African SMMEs. The problems addressed in this research are:

- investigating whether the concept of cloud computing and its related key terms are being comprehended by South African …

A Context-Aware Model To Improve Usability Of Information Display On Smartphone Apps For Emerging Users, Felix F. Ntawanga, Andre P. Calitz, Lynette Barnard

The African Journal of Information Systems

Smartphones have become a reliable technology for accessing information and services in rural communities. Mobile applications, such as social media and news apps running on smartphones, are no longer exclusively utilised by users in developed communities. Mobile applications are accessed in highly contextualised environments. This paper discusses a context-aware model that was implemented to improve the usability of information presented on smartphone applications for emerging users. User evaluation was conducted within a remote area in South Africa with a sample of users, most of whom did not have prior experience in using computer applications. The results of the evaluation present …

Factors Influencing The Use Of M-Banking By Academics: Case Study Sms-Based M-Banking, Gbolahan Olasina

The African Journal of Information Systems

There are several advantages with m-banking. Several related studies have shown that m-banking and indeed SMS-based mobile banking applications have become popular in many countries in Europe and America. The phenomenon remains not widely used in many others such as Nigeria. This study identified and investigated the factors that influence academics in Nigeria to use m- banking with focus on the evaluation of SMS-based mobile banking. The research model was adopted from the Unified Theory of Acceptance and Use of Technology model (UTAUT). A survey questionnaire was administered to collect data from 150 academic staff and 350 university students of …

Updating A Research Tradition By Examining The Effect Of New High Tech Channels On Consumer Search And Integrated Marketing: A Framework For Teaching, Deborah Fain, Mary Long

Atlantic Marketing Association Proceedings

As computers became more powerful in the late 80s and early 90s, large marketers began to try to push what became known as customer relationship management . Specifically, they began to evaluate various channels and how consumers navigated among them when making purchase decisions. Most of the examples at that time were anecdotal, and obviously considered traditional channels, both retail and direct. These included retail, direct mail, print, television, radio, telephone, early email, and a small amount of Internet. The impact of the Internet on new ways consumers navigate among the channels to collect information and make purchase decisions was …

The Role Of Gender And Geographic Factors In Virtual Team Communication Media Technology Selection With Respect To Coordination And Information Quality Needs, Jerry D. Wood

Theses and Dissertations

Research on virtual teams and how they function has become an important topic. This is due to organizations ever-increasing use of teams of globally dislocated employees, or virtual teams, to collaborate on projects to not only cut costs, but also create products that can be marketed and sold globally. Virtual team members need to share data to coordinate their efforts to meet those goals. To help reduce costs and improve speed, management often requires employees to use computer-mediated communication (CMC) technologies, such as email, to share data. When employees work within a virtual team, they are frequently required to collaborate …

Designing Multi-Target Salesforce Incentive Contract, Wenxin Huang

Lingnan Theses

Multi-target incentive contracts are widely observed in practice to stimulate salesforce effort. However, little is known about their effectiveness and the issues involved in designing them. In this thesis, we investigate the incentive contracting problem between a manufacturer and an agent when the realized sales of a product are affected by both the agent's selling effort and the type of the agent. The agent's type is uncertain to the manufacturer, whereas the agent can observe the actual type when exerting her selling effort. Again, this is unobservable by the manufacturer. For contract design problem, we develop a principal-agent model with …

This study aims to demonstrate how advanced data mining techniques such as text mining and cluster analysis can be used to improve visibility of procurement patterns and provide decision-makers with insight to develop more efficient sourcing strategies, in terms of cost and effort. A case study of an organization’s effort to improve its procurement process is presented in this paper. The findings from this study suggest that opportunities exist for organizations to aggregate common goods and services among the purchases made under and across …

Near Real-Time Retail Payment And Settlement Systems Mechanism Design, Zhiling Guo, Robert John Kauffman, Mei Lin, Dan Ma

Research Collection School Of Computing and Information Systems

Rapid expansion of e-commerce, along with rising domestic and cross-border payments, has fueled the demand among financial institutions for a cost-effective means to expedite clearing and settlement of low-value retail payments. These are called faster payments settlement systems. Traditionally, retail payments have made extensive use of interbank netting systems, in which payments are accumulated for end-of-day settlement. This approach, known as deferred net settlement (DNS), reduces the liquidity needs of the payment system, but bears inherent operational and financial risks for unsettled intraday payments. As large dollar volumes of retail payments accumulate, real-time gross settlement (RTGS) has been recognized as …

They have led to the increasing use of prior innovations that have supported e-commerce, and that are now being brought into financial services to support different kinds of improvements to core business processes. This research examines recent changes in the payment sector in financial services, specifically related to mobile payments (m-payments) that enable new channels for consumer payments for goods and services purchases, and other forms of economic exchange. We extend recent …

Joint Lead Time And Price Quotation : Dynamic Or Static?, Guo Zhang

Lingnan Theses

Intuitively, quoting dynamic lead time and price to customers based on real-time system state provides more efficient capacity utilization and increases revenue compared with quoting static lead time and price. However, dynamic quotation may require higher operational costs for the firm and it is often inconvenient to customers. This study aims to compare dynamic and static lead time and price quotations under fixed capacity and different potential demand rates. We hypothesize that there exists a potential demand rate under which the additional costs of dynamic quotation and the additional profit from dynamic quotation are equal. Thus static quotation may yield …
