Learning Image‐Text Associations, Tao Jiang, Ah-Hwee Tan
Research Collection School Of Computing and Information Systems
Web information fusion can be defined as the problem of collating and tracking information related to specific topics on the World Wide Web. Whereas most existing work on Web information fusion has focused on text-based multidocument summarization, this paper concerns the topic of image and text association, a cornerstone of cross-media Web information fusion. Specifically, we present two learning methods for discovering the underlying associations between images and texts based on small training data sets. The first method based on vague transformation measures the information similarity between the visual features and the textual features through a set of predefined domain-specific …

Multifactor Productivity And Idea Transmission Channels In The Malaysian Economy, Ester Shen Ai Chan
Multifactor Productivity And Idea Transmission Channels In The Malaysian Economy, Ester Shen Ai Chan
Dissertations and Theses Collection (Open Access)
This paper examines the contribution of multifactor productivity (MFP) growth to output per worker growth in Malaysia from 1961-2000. MFP growth is found to contribute about 74 percent to output per worker growth from 1987-2000, but has only minimal or negative contribution to growth in the earlier years. This paper then attempts to explain why MFP growth has such a large contribution to output per worker growth in the period 1987-2000 by looking at international trade as channel of technology or idea transfer from the G5 countries into Malaysia. MFP grows because ideas from these advanced nations are transferred into …
What Do Business School Deans Do? Insights From A Uk Study, Julie Davies, Howard Thomas
What Do Business School Deans Do? Insights From A Uk Study, Julie Davies, Howard Thomas
Research Collection Lee Kong Chian School Of Business
During the last 40 years, the growth and impact of UK business schools have been significant. Relatively few studies have reviewed how business school deans emerge and grow. This paper aims to explore the experiences and psychometric profiles of UK business school leaders to understand their tenures, problems, dilemmas and succession issues. The study comprised 16 semi-structured interviews with business school deans and Myers-Briggs Type Indicator (MBTI) questionnaires completed by deans and aspiring deans (associate deans and heads of department). The study uses the executive life cycle and concepts of social capital as theoretical frameworks to understand the dean's role. …

Changing To Daylight Saving Time Cuts Into Sleep And Increases Workplace Injuries, Christopher M. Barnes, David Turley Wagner
Research Collection Lee Kong Chian School Of Business
The authors examine the differential influence of time changes associated with Daylight Saving Time on sleep quantity and associated workplace injuries. In Study 1, the authors used a National Institute for Occupational Safety and Health database of mining injuries for the years 1983–2006, and they found that in comparison with other days, on Mondays directly following the switch to Daylight Saving Time—in which 1 hr is lost—workers sustain more workplace injuries and injuries of greater severity. In Study 2, the authors used a Bureau of Labor Statistics database of time use for the years 2003–2006, and they found indirect evidence …
A Petri Net-Based Approach To Reconfigurable Manufacturing Systems Modeling, Linda L. Zhang, Brian Rodrigues
A Petri Net-Based Approach To Reconfigurable Manufacturing Systems Modeling, Linda L. Zhang, Brian Rodrigues
Research Collection Lee Kong Chian School Of Business
Reconfigurable manufacturing systems (RMSs) have been used to provide manufacturing companies with the required capacities and capabilities, when needed. Recognizing (1) the importance of dynamic modeling and visualization in decision making support in RMSs and (2) the limitations of the existing studies, we model RMSs based on Petri net (PN) techniques with focus on the process of reconfiguring system elements while considering constraints and system performance. In response to the modeling difficulties identified, a new formalism of colored timed PNs is introduced. In conjunction with colored tokens and timing in colored PNs and timed PNs, we further define a reconfiguration …

The Application Of Single-Pass Heuristics For U-Lines, Jaydeep Balakrishnan, Chun Hung Cheng, Kin Chuen Ho, Kum Khiong Yang
Research Collection Lee Kong Chian School Of Business
U-lines have been adopted in many manufacturing settings as part of JIT implementation. In this paper, we examine the applicability of existing straight-line heuristics for obtaining a balance on a U-line. We modify 13 single-pass heuristics and study the effectiveness of various heuristics under different problem conditions. An extensive computational study is carried out to help identify the best heuristics. In addition, we compare recent U-line procedures with a single-pass heuristic using some literature problems. Based on a single-pass heuristic, we compare the configurations of a straight- and U-line. © 2009 The Society of Manufacturing Engineers.

Maximizing Throughput Of Bucket Brigades On Discrete Work Stations, Yun Fong Lim, Kum Khiong Yang
Maximizing Throughput Of Bucket Brigades On Discrete Work Stations, Yun Fong Lim, Kum Khiong Yang
Research Collection Lee Kong Chian School Of Business
One way to coordinate workers along an assembly line that has fewer workers than work stations is to form a bucket brigade. The throughput of a bucket brigade on discrete work stations may be compromised due to blocking even if workers are sequenced from slowest to fastest. For a given work distribution on the stations we find policies that maximize the throughput of the line. When workers have very different production rates, fully cross-training the workers and sequencing them from slowest to fastest is almost always the best policy. This policy outperforms other policies for most work distributions except for …

Modelling Situation Awareness For Context‐Aware Decision Support, Yu-Hong Feng, Teck-Hou Teng, Ah-Hwee Tan
Modelling Situation Awareness For Context‐Aware Decision Support, Yu-Hong Feng, Teck-Hou Teng, Ah-Hwee Tan
Research Collection School Of Computing and Information Systems
Situation awareness modelling is popularly used in the command and control domain for situation assessment and decision support. However, situation models in real-world applications are typically complex and not easy to use. This paper presents a Context-aware Decision Support (CaDS) system, which consists of a situation model for shared situation awareness modelling and a group of entity agents, one for each individual user, for focused and customized decision support. By incorporating a rule-based inference engine, the entity agents provide functions including event classification, action recommendation, and proactive decision making. The implementation and the performance of the proposed system are demonstrated …
When Is It Beneficial For A Firm To Pursue A Unified Procurement Strategy For Enterprise Software Solutions?, Robert J. Kauffman, Juliana Y. Tsai
When Is It Beneficial For A Firm To Pursue A Unified Procurement Strategy For Enterprise Software Solutions?, Robert J. Kauffman, Juliana Y. Tsai
Research Collection School Of Computing and Information Systems
The underlying structure of the enterprise software marketplace during the past ten years suggests that the arrangements that firms make with respect to the acquisition of such software capabilities will become increasingly concentrated. This article explores the multiple theoretical rationales and business cases for the move to a unified procurement strategy for enterprise software, reflecting some differences in terms of what might be expected from the predictions of the well known move-to-the-middle hypothesis. Our central argument is that a "move-to-the-middle" with more than just a single vendor is the likely outcome in unconsolidated industry markets. In industries experiencing consolidation, firms …

Doctrine And Fairness In The Law Of Contract, Andrew B.L. Phang
Research Collection Yong Pung How School Of Law
This paper explores, through illustrations from the law of contract, the important centraltheme to the effect that the rules and principles, which constitute thedoctrineof the law,are not ends in themselves but are, rather, the means through which the courts arrive atsubstantively fairoutcomes in the cases before them. The paper focuses on the concept of‘radicalism’, which relates to the point at which the courts decide that it is legallypermissible to hold that a contract should come to an end because a radical or funda-mental ‘legal tipping point’ has not only been arrived at but has, in fact, been crossed. Itexplores the …
A Semiotic Analysis Of Unified Modeling Language Graphical Notations, Keng Siau, Yuhong Tian
A Semiotic Analysis Of Unified Modeling Language Graphical Notations, Keng Siau, Yuhong Tian
Research Collection School Of Computing and Information Systems
Unified modeling language (UML) is the standard modeling language for object-oriented system development. Despite its status as a standard, UML has a fuzzy formal specification and a weak theoretical foundation. Semiotics, the study of signs, provides a good theoretical foundation for UML research because graphical notations (or visual signs) of UML are subjected to the principles of signs. In our research, we use semiotics to study the effectiveness of graphical notations in UML. We hypothesized that the use of iconic signs as UML graphical notations leads to representation that is more accurately interpreted and that arouses fewer connotations than the …
Signal Detection With Criterion Noise: Applications To Recognition Memory, Aaron S. Benjamin, Michael Diaz, Wee, Serena
Signal Detection With Criterion Noise: Applications To Recognition Memory, Aaron S. Benjamin, Michael Diaz, Wee, Serena
Research Collection School of Social Sciences
A tacit but fundamental assumption of the theory of signal detection is that criterion placement is a noise-free process. This article challenges that assumption on theoretical and empirical grounds and presents the noisy decision theory of signal detection (ND-TSD). Generalized equations for the isosensitivity function and for measures of discrimination incorporating criterion variability are derived, and the model's relationship with extant models of decision making in discrimination tasks is examined, An experiment evaluating recognition memory for ensembles of word stimuli revealed that criterion noise is not trivial in magnitude and contributes substantially to variance in the slope of the isosensitivity …
Making Sustainable Creative/Cultural Space In Shanghai And Singapore, Lily Kong
Making Sustainable Creative/Cultural Space In Shanghai And Singapore, Lily Kong
Research Collection School of Social Sciences
Shanghai and Singapore are two economically vibrant Asian cities that have recently adopted creative/cultural economy strategies. In this article I examine new spatial expressions of cultural and economic interests in the two cities: state-vaunted cultural edifices and organically evolved cultural spaces. I discuss the simultaneous precariousness and sustainability of these spaces, focusing on Shanghai's Grand Theatre and Moganshan Lu and on Singapore's Esplanade-Theatres by the Bay and Wessex Estate. Their cultural sustainability is understood as their ability to support the development of indigenous content and local idioms in artistic work. Their social sustainability is examined in terms of the social …
A Metaheuristic For The Pickup And Delivery Problem With Split-Loads And Its Extension, Dai Yao
A Metaheuristic For The Pickup And Delivery Problem With Split-Loads And Its Extension, Dai Yao
Dissertations and Theses Collection (Open Access)
In this dissertation, we study improvements in the Pickup and Delivery Problem that can be achieved by allowing multiple vehicle trips to serve a common load. We explore how costs can be reduced through the elimination of the constraint that a load must be served by only one vehicle trip. Specifically, we investigate the problem of routing vehicles to serve loads that have distinct origins and destinations, with no constraint on the amount of a load that a vehicle may serve at a time. We develop a metaheuristic to solve large scale practical size problems in this form and apply …
Does Morningstar Shine In The Universe Of Mutual Funds? A Study On Morningstar Mutual Fund Ratings, Wee Seng Ng
Does Morningstar Shine In The Universe Of Mutual Funds? A Study On Morningstar Mutual Fund Ratings, Wee Seng Ng
Dissertations and Theses Collection (Open Access)
Using data from Morningstar Principia CDs and employing standard methodologies, we examine the extent to which two mutual fund ratings: Morningstar star ratings and Morningstar stewardship grades can predict future fund performance. In particular, we investigate whether the combined predictive power of the two ratings exceeds that of a single rating. We decompose funds into various groups characterized by fund age and fund categories in order to address such issues as whether predictive performance is uniform across characteristic-based groups. Although our analysis shows that none of the ratings alone possesses strong predictive power, there is statistical evidence to support the …
The Effects Of Patent Characteristics As Signals On The Growth Of Follow-On Innovations: Evidence From Chinese Patenting Activities In U.S, Wenxin Guo
Dissertations and Theses Collection (Open Access)
As global trade and business activities intensified, cross-national patenting activities have been playing an increasingly important role in the process of innovation accumulation and growth. However, few studies (to my knowledge) have examined the characteristics of cross-national patents and their relationship to the accumulation and growth of innovation, especially in the context of a developing versus a developed country.
Motivated by the anecdotal evidence and `Patent Signaling Theory'(Spence, 1973), I investigate the possible influential factors on the `quality' of a US patent with a Chinese priority (thereafter `US-CN' patent) and their impact on the growth of follow-on innovation. By developing …
Quc-Tree: Integrating Query Context Information For Efficient Music Retrieval, Jialie Shen, Dacheng Tao, Xuelong Li
Quc-Tree: Integrating Query Context Information For Efficient Music Retrieval, Jialie Shen, Dacheng Tao, Xuelong Li
Research Collection School Of Computing and Information Systems
In this paper, we introduce a novel indexing scheme-query context tree (QUC-tree) to facilitate efficient query sensitive music search under different query contexts. Distinguished from the previous approaches, QUC-tree is a balanced multiway tree structure, where each level represents the data space at different dimensionality. Before the tree structure construction, principle component analysis (PCA) is applied for data analysis and transforming the raw composite features into a new feature space sorted by the importance of acoustic features. The PCA transformed data and reduced dimensions in the upper levels can alleviate suffering from dimensionality curse. To accurately mimic human perception, an …
The Paradox Of Victim-Centrism: Victim Participation At The Khmer Rouge Tribunal, Mahdev Mohan
The Paradox Of Victim-Centrism: Victim Participation At The Khmer Rouge Tribunal, Mahdev Mohan
Research Collection Yong Pung How School Of Law
It has been claimed - though not proved - that victims will be benefited by participation in international criminal tribunals. This article interrogates this claim in the context of victim participation at the Extraordinary Chambers in the Courts of Cambodia (ECCC), commonly referred to as the Khmer Rouge Tribunal. Based on interviews with Cambodian victims and Tribunal affiliates, it examines why and how the Tribunal permits victims to intervene as les parties civile, pulling together the normative and legal basis for this mode of victim participation. This article does not purport to generalize with confidence about Cambodian victims in general, …
