Estimating the future position of a deep sea vessel more than 24 hours in advance is a major challenge for Dutch logistics service providers (LSPs). Their unscheduled arrival in ports directly impacts scheduling and waiting times of barges, propagating throughout the entire supply chain network. To help LSPs' planners improve planning operations, we intend to capture the characteristics of maritime routes for a specific region (the North Sea connecting the Netherlands and United Kingdom) in the form of a directed graph, which can be used as a foundation for predicting destination and arrival time of each associated vessel. To create such graph we need an efficient way to extract waypoints for traffic data and this is the problem we will address in this paper. Since LSPs only use publicly available data for arrival estimation, our solution is entirely based on Automatic Identification System (AIS) data. Extracting positional information from AIS, we explore various machine learning approaches to identify clusters. We apply DBSCAN algorithm and show its advantages and disadvantages when used on AIS data. The same process is repeated using meta-heuristics, comparing clustering results generated by a genetic algorithm and by modified ant-colony optimization to those produced by DBSCAN. Finally, we present a hybrid approach and its ability to discover waypoints, highlighting the achieved improvements. To extend the problem, two constraints are added. The first is the requirement to handle large volumes of streaming AIS data on standard PC-based hardware. The second introduces the common situation of "dark areas" in a map due to problems with receiving and transmitting AIS data. The algorithm discovers route waypoints in efficient and effective ways under these constraints.

Earlier research showed firms with superior IT governance (ITG) have more than 20% higher profits than firms with poor governance given the same strategic objectives. This article forms part of an on-going independent research project on effectiveness and maturity of ITG. It is known that corporate governance (CG) and ITG are related. However, little is known on how this relation works. This relation can be described in several ways; for example, from a performance (added value) or a conformance (rules and regulation) perspective. Current governance research is largely focused on hard governance. Hard governance refers to elements like structures and processes. Soft governance is related to social aspects like human behavior and organizational culture. This study focuses on the relation between CG and ITG from a performance perspective and is based on a systematic literature review and a series of ten case studies. In the case studies an adjusted assessment instrument for hard and soft ITG was used. A systematic literature review was conducted to validate the relevance of the focus areas of this instrument for CG. The instrument used in the case studies was adjusted with a corporate perspective to be able to compare results from a corporate and a departmental (business and IT) perspective. Our research showed that an integrated approach for ITG and CG is needed, and what focus areas need attention in this relation. The value of this paper is twofold: It describes the basic outlines of the focus areas relating ITG and CG. Some of which are not yet getting a lot of attention in current research, especially continuous improvement and the informal organization. It lists the results from a series of ten cases studies, in which twelve focus areas have been discussed with sixty participants from a departmental (IT and business perspective) and a corporate perspective.

The scheduling process in a typical business environment consists of predominantly repetitive tasks that have to be completed in limited time and often containing some form of uncertainty. The intelligence amplification is a symbiotic relationship between a human and an intelligent agent. This partnership is organized to emphasize the strength of both entities, with the human taking the central role of the objective setter and supervisor, and the machine focusing on executing the repetitive tasks. The output efficiency and effectiveness increase as each partner can focus on its native tasks. We propose the intelligence amplification framework that is applicable in typical scheduling problems encountered in the business domain. Using this framework we build an artifact to enhance scheduling processes in synchromodal logistics, showing that a symbiotic decision maker performs better in terms of efficiency and effectiveness.

This paper studies the suitability of classrooms for higher education. We propose a model to quantify the suitability, which allows measuring and optimizing the fit of classrooms for a given curriculum event. This model is unique, as there is no such model yet in literature that provides insight into the variables and interrelationships that are relevant when assessing classrooms and their allocation in the timetables. We also present a case study in which we apply the model to the timetable allocations at the University of Twente, for both assessing the suitability of its classrooms, and assessing to what extent its timetables take the classroom suitability into account. We compared the measurements of the suitability to the perceptions that both teachers and the support services have towards the allocations of suitability, as a reference of the extent to which the measurements are recognizable in practice. There are two main contributions of the research in this paper. First, we make the suitability of classrooms for education quantifiable and measurable, enabling the allocation of suitability to be transparent, to improve it and to optimize it as a performance indicator of the timetables. Second, this research goes beyond the current dominant way of timetabling which tries to fit class sizes to room capacities, by introducing the maximization of value adding as a new way for optimizing the allocation of classroom-based education. The research in this paper describes a method with which the suitability of classrooms can be made measurable. By using this method, insight will be gained into the performance of timetables on the aspect of suitability.

Education logistics concerns the integral planning and control (P&C) of education related activities in education organizations, encompassing activities such as scheduling, facility management, staffing, performance management, curriculum development, and ICT management. It has a significant impact on the overall effectiveness and efficiency of the organization. The use of P&C needs to transcend the overtone of finance and aim for the much broader meaning of integral coordination or the organization. This paper introduces a new framework for education organizations to design, optimize, and govern their education logistics and its developments. It introduces hierarchical layers of P&C in a similar way as existing theoretical P&C frameworks for other sectors such as industry and healthcare, and distinguishes different process areas within these layers. We demonstrate that the current dominant way of P&C in education is falling short in numerous aspects, thereby impeding both innovation and the effective and efficient implementation of emerging educational paradigms. Our framework for smart education organizations counters current P&C deficiencies by closing existing coordination gaps between directive-, primary-, and support processes. Currently, these process areas in higher education organizations are often functionally dispersed through lack of horizontal alignment. Our framework defines and integrates levels of control for different process areas, thereby integrating and aligning decision making in the organization.

In this paper, we explore the use of serious gaming to raise awareness about some of the trade-offs in anticipatory scheduling of synchromodal transport and to educate on how to optimize these trade-offs. We design and implement a game, called Trucks & Barges, which simulates a logistics service provider that needs to assign containers to barges and trucks on a daily basis. The game consists of various types of game modes in which the player can either manually plan the containers or use advanced decision support. The game includes a leaderboard such that players can compete against each other. We discuss how active learning by means of the game facilitates the adoption of an anticipatory perspective when scheduling synchromodal transport operations.

Ever since its first manifesto in Greece around 3000 years ago, sports as a field has accumulated a long history with strong traditions while at the same time, gone through tremendous changes toward professionalization and commercialization. The current waves of digitalization have intensified its evolution, as digital technologies are increasingly entrenched in a wide range of sporting activities and for applications beyond mere performance enhancement. Despite such trends, research on sports digitalization in the IS discipline is surprisingly still nascent. This paper aims at establishing a discourse on sports digitalization within the discipline. Toward this, we first provide an understanding of the institutional characteristics of the sports industry, establishing its theoretical importance and relevance in our discipline; second, we reveal the latest trends of digitalization in the sports industry and unpack its implications for sports organizations; last, we propose an agenda for sports digitalization research in IS.

Over the past few years, academics have witnessed an increasing amount of attention being accorded to games as learning tools. According to several researchers, Serious Games (SGs) can assist learning by emerging as an alternate means of presenting instructions. Whilst SGs are increasingly gaining acceptance as a learning tool, their application in formal education remains rather limited, which underpins the importance about understanding what makes a game effective and how it must be used in classrooms. Given that teachers play a key role in shaping and responding to the intricate contextual factors influencing the manner in which games are experienced across educational settings, their opinions on what SGs can possibly accomplish in educational settings would inexorably impact the decisions relating to when, how, and for what purposes they would be incorporated in classrooms. Against this backdrop, this study administered a survey online and in hardcopy to ascertain teachers’ perceptions on SGs and their effect on their contribution as a teacher. It also pinpointed the challenges and impediments of utilizing SGs in classrooms through teachers’ perspective, which illuminated the attitudes teachers generally bring to games-based learning environments. According to the findings, teachers are typically open to using SGs in their classrooms. Overall, it can be inferred that the design/development of SGs aimed at formal education can benefit significantly by adopting game features and surmounting the hurdles addressed by teachers.

Social media has become a popular tool in the political landscape. As a result, it is of increased importance to evaluate social media campaigns of politicians. However, there is currently little knowledge how to measure and evaluate the influence of social media in political campaigns, especially at the local scale. This chapter is a step further towards the development of a theoretical framework and an algorithm that contributes to more reliable impact measurement of social media campaigns by politicians. The Social Media Indicator-2 framework and a related scoring algorithm are introduced to evaluate the influence of individual political candidates via social media on their social environment. The framework is tested by applying it in an empirical pilot study based on the local 2014 municipal elections in the Netherlands. We collected data for the political candidates and their parties in a pre-defined period and were able to relate scores to voting outcome. Positive correlations were revealed between social media contribution scores of politicians and their preference votes within the province of Overijssel in the Netherlands.

Student feedback analysis is time-consuming and laborious work if it is handled manually. This study explores the use of a new deep learning-based method to design a more accurate automated system for analysing students’ feedback (called DTLP: deep learning and teaching process). The DTLP employs convolutional neural networks (CNNs), bidirectional LSTM (BiLSTM), and attention mechanism.To the best of our knowledge, a deep learning-based method using a unified feature set, which is representative of word embedding, sentiment knowledge, sentiment shifter rules, linguistic and statistical knowledge, has not been thoroughly studied with regard to sentiment analysis of student feedback. Furthermore, DTLP uses multiple strategies to overcome the following drawbacks: contextual polarity; sentence types; words with similar semantic context but opposite sentiment polarity; word coverage limit of an individual lexicon; and word sense variations. To evaluate the DTLP, we conducted an experimen...

The pervasive use of technology has created a critical dependency on Information Technology (IT) that requires IT Governance (ITG). ITG calls for the definition and implementation of formal mechanisms at the highest level in the organization taking into account structures, processes and relational mechanisms for the creation of business value from IT investments. However, determining the right ITG mechanisms remains a complex endeavour. Previous studies have identified ITG mechanisms in use in the financial and health care industries. While universities also increasingly depend on IT for their success, ITG implementation in universities has not received much attention. As universities have many unique characteristics, it is highly unlikely that ITG experiences from the financial and health care industries can be directly applied to universities. Therefore, the purpose of this research is to identify an ITG mechanisms’ baseline for universities. Six case studies comprising of in-dept...

Higher Education Institutions (HEIs) are under constant competitive pressure, resulting in the increased importance of achieving both efficiency and effectiveness in such organizations. This intensifies the importance of selecting a suitable timetabling software application, which can be considered to be at the heart of the organization, as it supports organizing the primary process. The timetable software regulates the scheduling of teachers, students and staff, and thus significantly impacts on their effectiveness and efficiency. The selection of such an important application is an essential first step for managing and controlling the schedules.

Airports have become the center hubs of supply chain collaborations. To support the air freight collaborations in airports, Cargo Community Systems (CCSs) was developed. A CCS is not only an enabler but also a challenge for establishing and maintaining collaborations. A proper understanding of how to govern the relationships between companies in the community is needed to achieve a sustainable collaboration. This study presents the development of Amsterdam Schiphol Airport’s CCS – Cargonaut. The air freight community in Schiphol Airport has been through two lifecycles of governance. The main differences between the first lifecycle (1981-1995) and the second lifecycle (1996-now) are: (1) Cargonaut’s ownership, (2) the cost-sharing structure, and (3) the member’s power in the decision making. From Cargonaut’s development, we can conclude that the governance of inter-organizational collaboration over time is dynamic. Schiphol community has been successful in creating business value and...

Dit artikel is een weergave van presentaties en rondetafelgesprekken op een bijeenkomst over informatiemanagement in het onderwijs op 8 oktober 2008. Allereerst schetst Erik Rutkens een aantal organisatorische en IT-ontwikkelingen in het onderwijs. Informatiemanagement kan instellingen helpen om adequaat op deze ontwikkelingen in te spelen. Aan de orde komen: de definitie van informatiemanagement, enkele theoretische modellen, en knelpunten bij informatiemanagement in het onderwijs. Tot slot wordt aan de hand van een praktijkvoorbeeld getoond hoe onderwijsinstellingen informatiemanagement effectief kunnen organiseren. Jos van Hillegersberg gaat vervolgens in op een aantal trends die het gevolg zijn van de ‘service-economie’, de gevolgen en/of mogelijkheden voor het onderwijs en de rol van informatiemanagement.
