Much effort has been concentrated in the eighties on IT strategy and many companies today have an IT investment portfolio. Managing the benefits of the investment portfolio presents new challenges. The author has previously published the first stage to a method for linking investment strategy to benefits and in this paper discusses the second of the process when it is necessary to identify benefits for specific investments to ensure their realization. The process ensures that sponsors not only understand the impact of the investment on key operating variables but also take responsibility for ensuring the improved performance.

The uncertainty of IT investment payoff should be reflected in other managerial decisions. This research examines Rozeff's (1982) agency cost/transaction cost tradeoff model to determine if IT investments are related to dividend payout ratios for an organization. A dividend payout model including an IT investment variable is estimated. The estimation results suggest that a significant positive relationship exists between dividend payout and a firm&rsquo;s IT investments.</span></span></span></p>

The Relationship

The relationship between information technology (IT) investment and non-financial measures of organizations has been studied mostlyin the developed countries. These studies are mostly conducted in the context of banking, securities and manufacture sectors. Therefore, a study that examine the impact of IT investments in the context of developing countries and other sectors,such as higher educationwill be worth studied. The current study is empirically examined the relationship between IT investment and organizational efficiency in public sector. Eighteen Faculties within Universitas Gadjah Mada (UGM) which is one of the autonomous state owned universities in Indonesia have been used as sampel. Data were obtained from year 2013 to 2015. Data were analyzed using panel data regression. The result shows that IT investment positively affects efficiency in the entity.Key Words: Efficiency, Productivity Paradox, IT investment,

The Impact

The study aims to develop a dynamic model for the management of a strategic investment portfolio, taking into account the impact of crisis processes on asset value. A mathematical model of a dynamic portfolio strategy is developed, and guidelines for framing a long-term investment strategy based on the current state of the investment market are formalized. An efficient method of long-term ensemble forecasting to increase the accuracy of predicting financial time series is elaborated. A methodology for constructing and rebalancing a dynamic strategic investment portfolio based on a changing portfolio strategy that results from assessing the current market state and forecast is developed. The obtained strategic portfolio model has been estimated empirically based on historical data and its rate-of-return characteristics have been compared with those of the existing conventional models used in strategic investment.

The Impact

In modern organisations a large portion of senior management’s time is now being spent on finding ways to measure the contribution of their organisations’ IS/IT investments to business performance. It has been shown that IS/IT investments in many organisations are huge and increasing rapidly every year and yet there is still a lack of understanding of the impact of the proper IS/IT investment evaluation processes and practices in these organisations. At the same time, the issue of expected and actual benefits realised from IS/IT investments has also generated a significant amount of debate in the IS/IT literature amongst the researchers and practitioners. This is as true in Australia as it is in the rest of the developed world. Thus, one can argue that a detailed program of research into the current practice and process of IS/IT investment evaluation in Australia is warranted. This paper reviews the progress made in research in this area and proposes a research program incorporating surveys, case studies, and expert focus groups to assess current practice and to develop an approach, model or framework based on the fit between theory and practice of IS/IT investment evaluation by large Australian organisations.

The Impact

Objective: In this paper, Decode-and-Forward (DF) mode is deployed in the Relay Selection (RS) scheme to provide better performance in cooperative downlink Non-orthogonal Multiple Access (NOMA) networks. In particular, evaluation regarding the impact of the number of multiple relays on outage performance is presented. Methods: As main parameter affecting cooperative NOMA performance, we consider the scenario of the fixed power allocations and the varying number of relays. In addition, the expressions of outage probabilities are the main metric to examine separated NOMA users. By matching related results between simulation and analytical methods, the exactness of derived formula can be verified. Results: The intuitive main results show that in such cooperative NOMA networks, the higher the number of relays equipped, the better the system performance can be achieved. Conclusion: DF mode is confirmed as a reasonable selection scheme to improve the transmission quality in NOMA. In future work, we will introduce new relay selections to achieve improved performance.

Distributed Machine Learning

Rachid Guerraoui was the rst keynote speaker, and he got things o to a great start by discussing the broad relevance of the research done in our community relative to both industry and academia. He rst argued that, in some sense, the fact that distributed computing is so pervasive nowadays could end up sti ing progress in our community by inducing people to work on marginal problems, and becoming isolated. His rst suggestion was to try to understand and incorporate new ideas coming from applied elds into our research, and argued that this has been historically very successful. He illustrated this point via the distributed payment problem, which appears in the context of blockchains, in particular Bitcoin, but then turned out to be very theoretically interesting; furthermore, the theoretical understanding of the problem inspired new practical protocols. He then went further to discuss new directions in distributed computing, such as the COVID tracing problem, and new challenges in Byzantine-resilient distributed machine learning. Another source of innovation Rachid suggested was hardware innovations, which he illustrated with work studying the impact of RDMA-based primitives on fundamental problems in distributed computing. The talk concluded with a very lively discussion.

Using contingency theory, we argue that there is not a uniform approach for companies to govern information technology (IT) investments. Rather, the level of governance over IT investments is contingent upon the organization’s goals for its IT investments. We find that Australian organizations with both operation- and market-focused IT investment goals (i.e. dual-focused IT goals) demonstrate higher IT investment governance (ITIG) levels than those with less focused IT goals. We also document that dual-IT-focused firms that do not implement high levels of ITIG underperform. Our study informs business executives, boards of directors, and other practitioners interested in governance implementations over IT investments. JEL Classification: M1

Video Format

Millions of students follow online classes which are delivered in video format. Several studies examine the impact of these video formats on engagement and learning using explicit measures and outline the need to also investigate the implicit cognitive and emotional states of online learners. Our study compared two video formats in terms of engagement (over time) and learning in a between-subject experiment. Engagement was operationalized using explicit and implicit neurophysiological measures. Twenty-six (26) subjects participated in the study and were randomly assigned to one of two conditions based on the video shown: infographic video or lecture capture. The infographic video showed animated graphics, images, and text. The lecture capture showed a professor, providing a lecture, filmed in a classroom setting. Results suggest that lecture capture triggers greater emotional engagement over a shorter period, whereas the infographic video maintains higher emotional and cognitive engagement over longer periods of time. Regarding student learning, the infographic video contributes to significantly improved performance in matters of difficult questions. Additionally, our results suggest a significant relationship between engagement and student performance. In general, the higher the engagement, the better the student performance, although, in the case of cognitive engagement, the link is quadratic (inverted U shaped).

The Impact

This paper presents the development of an equation based model to simulate the combined heat and mass transfer in the desiccant wheels. The performance model is one dimensional in the axial direction. It applies a lumped formulation in the thickness direction of the desiccant and the substrate. The boundary conditions of this problem represent the inlet outside/process and building exhaust/regeneration air conditions as well as the adiabatic condition of the two ends of the desiccant composite. The solutions of this model are iterated until the wheel reaches periodic steady state operation. The modeling results are obtained as the changes of the outside/process and building exhaust/regeneration air conditions along the wheel depth and the wheel rotation. This performance model relates the wheel’s design parameters, such as the wheel dimension, the channel size and the desiccant properties, and the wheel’s operating variables, such as the rotary speed and the regeneration air flowrate, to its operating performance. The impact of some practical issues, such as wheel purge, residual water in the desiccant and the wheel supporting structure, on the wheel performance has also been investigated.
