Conditional Proxy Broadcast Re-Encryption, Cheng-Kang Chu, Jian Weng, Sherman S. W. Chow, Jianying Zhou, Robert H. Deng
Conditional Proxy Broadcast Re-Encryption, Cheng-Kang Chu, Jian Weng, Sherman S. W. Chow, Jianying Zhou, Robert H. Deng
Research Collection School Of Computing and Information Systems
A proxy re-encryption (PRE) scheme supports the delegation of decryption rights via a proxy, who makes the ciphertexts decryptable by the delegatee. PRE is useful in various applications such as encrypted email forwarding. In this paper, we introduce a more generalized notion of conditional proxy broadcast re-encryption (CPBRE). A CPBRE scheme allows Alice to generate a re-encryption key for some condition specified during the encryption, such that the re-encryption power of the proxy is restricted to that condition only. This enables a more fine-grained delegation of decryption right. Moreover, Alice can delegate decryption rights to a set of users at …
Automatic Steering Of Behavioral Model Inference, David Lo, Leonardo Mariani, Mauro Pezze
Automatic Steering Of Behavioral Model Inference, David Lo, Leonardo Mariani, Mauro Pezze
Research Collection School Of Computing and Information Systems
Many testing and analysis techniques use finite state models to validate and verify the quality of software systems. Since the specification of such models is complex and time-consuming, researchers defined several techniques to extract finite state models from code and traces. Automatically generating models requires much less effort than designing them, and thus eases the verification and validation of large software systems. However, when models are inferred automatically, the precision of the mining process is critical. Behavioral models mined with imprecise processes can include many spurious behaviors, and can thus compromise the results of testing and analysis techniques that use …
Learning And Inferencing In User Ontology For Personalized Semantic Web Search, Xing Jiang, Ah-Hwee Tan
Learning And Inferencing In User Ontology For Personalized Semantic Web Search, Xing Jiang, Ah-Hwee Tan
Research Collection School Of Computing and Information Systems
User modeling is aimed at capturing the users’ interests in a working domain, which forms the basis of providing personalized information services. In this paper, we present an ontology based user model, called user ontology, for providing personalized information service in the Semantic Web. Different from the existing approaches that only use concepts and taxonomic relations for user modeling, the proposed user ontology model utilizes concepts, taxonomic relations, and non-taxonomic relations in a given domain ontology to capture the users’ interests. As a customized view of the domain ontology, a user ontology provides a richer and more precise representation of …

The Military Leadership of Matilda of Canossa is an important and welcome book.Although Matilda is readily acknowledged as a pivotal political figure of Italian,reform, and indeed even papal history in the eleventh and early twelfth centuries,she continues to be a rather poorly studied individual, especially in English-languagescholarship, despite the extensive range of primary sources for her life, including manydiplomata, which have recently been critically re-edited. At the same time, almost noattention has been given to Matilda’s military leadership, even though she was credited(and also censured) for her campaigns on behalf of the reforming papacy. Impeccablyresearched and cogently argued, this new …
School Entry, Educational Attainment And Quarter Of Birth: A Cautionary Tale Of Late, Rashmi Barua, Kevin Lang
School Entry, Educational Attainment And Quarter Of Birth: A Cautionary Tale Of Late, Rashmi Barua, Kevin Lang
Research Collection School Of Economics
Partly in response to increased testing and accountability, states and districts have been raising the minimum school entry age, but existing studies show mixed results regarding the effects of entry age. These studies may be severely biased because they violate the monotonicity assumption needed for LATE. We propose an instrument not subject to this bias and show no effect on the educational attainment of children born in the fourth quarter of moving from a December 31 to an earlier cutoff. We then estimate a structural model of optimal entry age that reconciles the different IV estimates including ours. We find …
Efficient Parameter Estimation In Longitudinal Data Analysis Using A Hybrid Gee Method, Denis H. Y. Leung, You Gan Wang, Min Zhu
Efficient Parameter Estimation In Longitudinal Data Analysis Using A Hybrid Gee Method, Denis H. Y. Leung, You Gan Wang, Min Zhu
Research Collection School Of Economics
The method of generalized estimating equations (GEEs) provides consistent estimates of the regression parameters in a marginal regression model for longitudinal data, even when the working correlation model is misspecified (Liang and Zeger, 1986). However, the efficiency of a GEE estimate can be seriously affected by the choice of the working correlation model. This study addresses this problem by proposing a hybrid method that combines multiple GEEs based on different working correlation models, using the empirical likelihood method (Qin and Lawless, 1994). Analyses show that this hybrid method is more efficient than a GEE using a misspecified working correlation model. …
Can A Representative-Agent Model Represent A Heterogeneous-Agent Economy, Sungbae An, Yongsung Chang, Sun-Bin Kim
Can A Representative-Agent Model Represent A Heterogeneous-Agent Economy, Sungbae An, Yongsung Chang, Sun-Bin Kim
Research Collection School Of Economics
Accounting for observed fluctuations in aggregate employment, consumption, and real wage using the optimality conditions of a representative household requires preferences that are incompatible with economic priors. In order to reconcile theory with data, we construct a model with heterogeneous agents whose decisions are difficult to aggregate because of incomplete capital markets and the indivisible nature of labor supply. If we were to explain the model-generated aggregate time series using decisions of a stand-in household, such a household must have a nonconcave or unstable utility as is often found with the aggregate US data.
A Bayesian Approach Integrating Regional And Global Features For Image Semantic Learning, Luong-Dong Nguyen, Ghim-Eng Yap, Ying Liu, Ah-Hwee Tan, Liang-Tien Chia, Joo-Hwee Lim
A Bayesian Approach Integrating Regional And Global Features For Image Semantic Learning, Luong-Dong Nguyen, Ghim-Eng Yap, Ying Liu, Ah-Hwee Tan, Liang-Tien Chia, Joo-Hwee Lim
Research Collection School Of Computing and Information Systems
In content-based image retrieval, the “semantic gap” between visual image features and user semantics makes it hard to predict abstract image categories from low-level features. We present a hybrid system that integrates global features (Gfeatures) and region features (R-features) for predicting image semantics. As an intermediary between image features and categories, we introduce the notion of mid-level concepts, which enables us to predict an image’s category in three steps. First, a G-prediction system uses G-features to predict the probability of each category for an image. Simultaneously, a R-prediction system analyzes R-features to identify the probabilities of mid-level concepts in that …
Exploring Inter-Concept Relationship With Context Space For Semantic Video Indexing, Xiao-Yong Wei, Yu-Gang Jiang, Chong-Wah Ngo
Exploring Inter-Concept Relationship With Context Space For Semantic Video Indexing, Xiao-Yong Wei, Yu-Gang Jiang, Chong-Wah Ngo
Research Collection School Of Computing and Information Systems
Semantic concept detectors are often individually and independently developed. Using peripherally related concepts for leveraging the power of joint detection, which is referred to as context-based concept fusion (CBCF), has been one of the focus studies in recent years. This paper proposes the construction of a context space and the exploration of the space for CBCF. Context space considers the global consistency of concept relationship, addresses the problem of missing annotation, and is extensible for cross-domain contextual fusion. The space is linear and can be built by modeling the inter-concept relationship through annotation provided by either manual labeling or machine …
Continuous Obstructed Nearest Neighbor Queries In Spatial Databases, Yunjun Gao, Baihua Zheng
Continuous Obstructed Nearest Neighbor Queries In Spatial Databases, Yunjun Gao, Baihua Zheng
Research Collection School Of Computing and Information Systems
In this paper, we study a novel form of continuous nearest neighbor queries in the presence of obstacles, namely continuous obstructed nearest neighbor (CONN) search. It considers the impact of obstacles on the distance between objects, which is ignored by most of spatial queries. Given a data set P, an obstacle set O, and a query line segment q in a two-dimensional space, a CONN query retrieves the nearest neighbor of each point on q according to the obstructed distance, i.e., the shortest path between them without crossing any obstacle. We formulate CONN search, analyze its unique properties, and develop …
The Effects Of Response Instructions On Situational Judgment Test Performance And Validity In A High-Stakes Context, Filip Lievens, Paul R. Sackett, Tine Buyse
The Effects Of Response Instructions On Situational Judgment Test Performance And Validity In A High-Stakes Context, Filip Lievens, Paul R. Sackett, Tine Buyse
Research Collection Lee Kong Chian School Of Business
This study fills a key gap in research on response instructions in situational judgment tests (SJTs). The authors examined whether the assumptions behind the differential effects of knowledge and behavioral tendency SJT response instructions hold in a large-scale high-stakes selection context (i.e., admission to medical college). Candidates (N = 2,184) were randomly assigned to a knowledge or behavioral tendency response instruction SJT, while SJT content was kept constant. Contrary to prior research in low-stakes settings, no meaningfully important differences were found between mean scores for the response instruction sets. Consistent with prior research, the SJT with knowledge instructions correlated more …

Research Collection Lee Kong Chian School Of Business
Taking notes is of uttermost importance in academic and commercial use and success. Different techniques for note-taking utilise different cognitive processes and strategies. This experimental study examined ways to enhance cognitive performance via different note-taking techniques. By comparing performances of traditional, linear style note-taking with alternative non-linear technique, we aimed to examine the efficiency and importance of different ways of taking notes. Twenty-six volunteer adult learners from an information management course participated in this study. Cognitive performance scores from a traditional linear note-taking group were compared with another group by using a commercially available non-linear note-taking technique. Both groups were …
From Clampdown To Limited Empowerment: Hard And Soft Law In The Calibration And Regulation Of Religious Conduct In Singapore, Eugene K. B. Tan
From Clampdown To Limited Empowerment: Hard And Soft Law In The Calibration And Regulation Of Religious Conduct In Singapore, Eugene K. B. Tan
Research Collection Yong Pung How School Of Law
The focus of Singapore's response to terrorism post 9/11 has been to reach out to the “moderate, mainstream” Muslims as a bulwark against societal implosion. This article examines the broad-based endeavor toward “religious moderation.” While coercive draconian legislation remain the mainstay against extremists and radicals, the mobilization of soft law, aspirational norms, and values are consciously woven into the state's endeavors to enhance society's resilience and cohesion. They also seek to regulate religious conduct at a time when the state wishes to entrench secularism as a cornerstone of the governance of a multi-racial, multireligious society. Rights and regulation are not …
Abusive Supervision, Intentions To Quit, And Employees' Workplace Deviance: A Power/Dependence Analysis, Bennett J. Tepper, Jon C. Carr, Denise M. Breaux, Sharon Geider, Changya Hu, Wei Hua
Abusive Supervision, Intentions To Quit, And Employees' Workplace Deviance: A Power/Dependence Analysis, Bennett J. Tepper, Jon C. Carr, Denise M. Breaux, Sharon Geider, Changya Hu, Wei Hua
Research Collection Lee Kong Chian School Of Business
We conducted a two-study examination of relationships between abusive supervision and subordinates’ workplace deviance. Consistent with predictions derived from power/dependence theory, the results of a cross-sectional study with employees from three organizations suggest that abusive supervision is more strongly associated with subordinates’ organization deviance and supervisor-directed deviance when subordinates’ intention to quit is higher. The results also support the prediction that when intention to quit is higher, abusive supervision is more strongly associated with supervisor-directed deviance than with organization-directed deviance. These results were replicated in a second study, a two-wave investigation of people employed in a variety of industries and …
Imbree V Mcneilly: A View From Singapore, Yihan Goh
Imbree V Mcneilly: A View From Singapore, Yihan Goh
Research Collection Yong Pung How School Of Law
In Imbree v. McNeilly, the High Court of Australia ruled that a learner driver is no longer to be held to the standard of a reasonable but unqualified (and inexperienced) driver in negligence claims. It is the modest aim of this case note to show that Imbree, while a decision on a narrow point, in fact hints at a larger difficulty in the ascertainment of the standard of care in individual cases. It is in this context that it will be suggested that, when the time comes for Singapore courts to consider the applicability of Imbree, this difficulty should be …

Fair Model Checking With Process Counter Abstraction, Jun Sun, Yang Liu, Abhik Roychoudhury, Shanshan Liu, Jin Song Dong
Research Collection School Of Computing and Information Systems
Parameterized systems are characterized by the presence of a large (or even unbounded) number of behaviorally similar processes, and they often appear in distributed/concurrent systems. A common state space abstraction for checking parameterized systems involves not keeping track of process identifiers by grouping behaviorally similar processes. Such an abstraction, while useful, conflicts with the notion of fairness. Because process identifiers are lost in the abstraction, it is difficult to ensure fairness (in terms of progress in executions) among the processes. In this work, we study the problem of fair model checking with process counter abstraction. Even without maintaining the process …
Model Checking Linearizability Via Refinement, Yang Liu, Wei Chen, Yanhong A. Liu, Jun Sun
Model Checking Linearizability Via Refinement, Yang Liu, Wei Chen, Yanhong A. Liu, Jun Sun
Research Collection School Of Computing and Information Systems
Linearizability is an important correctness criterion for implementations of concurrent objects. Automatic checking of linearizability is challenging because it requires checking that 1) all executions of concurrent operations be serializable, and 2) the serialized executions be correct with respect to the sequential semantics. This paper describes a new method to automatically check linearizability based on refinement relations from abstract specifications to concrete implementations. Our method avoids the often difficult task of determining linearization points in implementations, but can also take advantage of linearization points if they are given. The method exploits model checking of finite state systems specified as concurrent …
Seven Ways To Reinvent Business For The Age Of Capability, Knowledge@Smu
Seven Ways To Reinvent Business For The Age Of Capability, Knowledge@Smu
Knowledge@SMU
It is time to break out of the old mould. The current economic crisis has shown quite clearly enough, that the old practices of running businesses since the Second World War cannot be sustained. Companies, including world-class multinationals, are not destroyed by competition. In a sense, they self-destruct when they are too slow in adapting to shifting operating environments. For business leaders, they are getting a wake up call. Jagdish Sheth, marketing professor from Emory University, suggests how companies can reinvent the way they do business.

Why Should Investors Stay Positive On The Asian Real Estate Markets?, Knowledge@Smu
Knowledge@SMU
Asia’s real estate market has weakened in tandem with lower equity prices. Singapore is no exception. Gone (for now) is the frenzied buying that marked 2007 and 2008, as everyone hunkers down for a possible protracted slump in the global economy. Many property buyers are caught with assets declining in value. Should investors thus stay away from Asia’s property market? What are the challenges facing the industry players, and is there a recovery on the horizon?

Research Collection School Of Economics
We conduct a field experiment in a large real-world social network to examine how subjects expect to be treated by their friends and by strangers who make allocation decisions in modified dictator games. Although recipients’ beliefs accurately account for the extent to which friends will choose more generous allocations than strangers (i.e., directed altruism), recipients are not able to anticipate individual differences in the baseline altruism of allocators (measured by giving to an unnamed recipient, which is predictive of generosity toward named recipients). Recipients who are direct friends with the allocator, or even recipients with many common friends, are no …

Market-Based Capabilities And Financial Performance Of Firms: Insights Into Marketing's Contribution To Firm Value, Sridhar N. Ramaswami, Rajendra K. Srivastava, Mukesh Bhargava
Research Collection Lee Kong Chian School Of Business
While there is recognition that market-based capabilities contribute to a firm’s financial performance, the exposition is largely conceptual (Srivastava et al. Journal of Marketing 62:2–18, 1998; Journal of Marketing 63:168–179, 1999). Using a resource based view of the firm, the present study proposes that (1) market-based assets and capabilities of a firm impacts (2) performance in three market-facing business processes (new product development, supply-chain and customer management), which in turn, influence (3) the firm’s financial performance. It develops related hypotheses and tests the framework empirically. The study also examines for the first time the interrelationship among the three business processes …

Simplenpkl: Simple Non-Parametric Kernel Learning, Jinfeng Zhuang, Ivor Tsang, Steven C. H. Hoi
Research Collection School Of Computing and Information Systems
Previous studies of Non-Parametric Kernel (NPK) learning usually reduce to solving some Semi-Definite Programming (SDP) problem by a standard SDP solver. However, time complexity of standard interior-point SDP solvers could be as high as O(n6.5). Such intensive computation cost prohibits NPK learning applicable to real applications, even for data sets of moderate size. In this paper, we propose an efficient approach to NPK learning from side information, referred to as SimpleNPKL, which can efficiently learn non-parametric kernels from large sets of pairwise constraints. In particular, we show that the proposed SimpleNPKL with linear loss has a closed-form solution that can …

Effects Of Country-Level Legal, Extra-Legal And Political Institutions On Auditing: A Cross-Country Analysis Of The Auditor Specialization Premium, Bin Sirinidhi, Chee Yeow Lim, Mahmud Hossain
Research Collection School Of Accountancy
In this cross-country study of the specialist auditor premium, which spans the US and 12 other countries, we provide evidence that country-level institutional strength increases average audit fees, but reduces the incremental demand for specialist auditors. This finding supports the hypothesis that strong institutions and the demand for specialist knowledge act as substitutes in providing the requisite assurance of financial statements.
Deterministic Chaos In A Model Of Discrete Manufacturing, John J. Iii Bartholdi, Donald D. Eisenstein, Yun Fong Lim
Deterministic Chaos In A Model Of Discrete Manufacturing, John J. Iii Bartholdi, Donald D. Eisenstein, Yun Fong Lim
Research Collection Lee Kong Chian School Of Business
A natural extension of the bucket brigade model of manufacturing is capable of chaotic behavior in which the product intercompletion times are, in effect, random, even though the model is completely deterministic. This is, we believe, the first proven instance of chaos in discrete manufacturing. Chaotic behavior represents a new challenge to the traditional tools of engineering management to reduce variability in production lines. Fortunately, if configured correctly, a bucket brigade assembly line can avoid such pathologies.

Salespeople's Renqing Orientation, Self-Esteem, And Selling Behaviors: An Empirical Study In Taiwan, Ming-Hong Tsai, Shu-Cheng Steve Chi, Hsia-Hua Hu
Research Collection School of Social Sciences
The purpose of this study was to investigate how salespeople's renqing orientation and self-esteem jointly affect their selling behavior. Data were obtained from a survey of salespeople from 17 pharmaceutical and consumer-goods companies in Taiwan (n = 216).Salespeople's renqing orientation (i.e., their propensity to adhere to the accepted norm of reciprocity) compensates the negative effect of self-esteem on their selling behaviors, such as adaptive selling and hard work. Our study results underscore the critical role of the character trait of renqing orientation in a culture emphasizing a norm of reciprocity. Therefore, it would be useful to consider a strategy of …

Mferio: The Design And Evaluation Of A Peer-To-Peer Mobile Payment System, Rajesh Krishna Balan, Narayanasamy Ramasubbu, Komsit Prakobphol, Nicolas Christin, Jason Hong
Research Collection School Of Computing and Information Systems
In this paper, we present the design and evaluation of a near-field communication-based mobile p2p payment application, called mFe-rio, that is designed to replace cash-based transactions. We first identify design criteria that payment systems should satisfy and then explain how mFerio, relative to those criteria, improves on the limitations of cash-based systems. We next describe mFerio's implementation and user interface design, focusing on the balance between usability and security. Finally, we present the results of a two-phase user study, involving a total of 104 people, that shows that mFerio has low cognitive load and is also fast, accurate, and easy …

Non-Redundant Sequential Rules - Theory And Algorithm, David Lo, Siau-Cheng Khoo, Limsoon Wong
Research Collection School Of Computing and Information Systems
A sequential rule expresses a relationship between two series of events happening one after another. Sequential rules are potentially useful for analyzing data in sequential format, ranging from purchase histories, network logs and program execution traces. In this work, we investigate and propose a syntactic characterization of a non-redundant set of sequential rules built upon past work on compact set of representative patterns. A rule is redundant if it can be inferred from another rule having the same support and confidence. When using the set of mined rules as a composite filter, replacing a full set of rules with a …

Modelling Reconfigurable Manufacturing Systems With Coloured Timed Petri Nets, Lianfeng Zhang, Brian Rodrigues
Research Collection Lee Kong Chian School Of Business
Reconfigurable manufacturing systems (RMSs) have been acknowledged as a promising means of providing manufacturing companies with the required production capacities and capabilities. This is accomplished through reconfiguring system elements over time for a diverse set of individualised products often required in small quantities and with short delivery lead times. Recognising the importance of dynamic modelling and visualisation in decision-making support in RMSs and the limitations of current research, we propose in this paper to model RMSs with Petri net (PN) techniques with focus on the process of reconfiguring system elements while considering constraints and system performance. In view of the …

Information Sharing And Strategic Signaling In Supply Chains, Robert J. Kauffman, Hamid Mohtadi
Research Collection School Of Computing and Information Systems
Information sharing in procurement occurs in rich and varied industry contexts in which managerial decisions are made and organizational strategy is formulated. We explore how information sharing ought to work in procurement contexts that involve investments in inter-organizational information systems (IOS) and collaborative planning, forecasting and replenishment (CPFR) practices. How and under what circumstances does a firm that plays the role of a supply chain buyer decide to share information on key variables, such as point-of-sale consumer demand data with its supplier, up the supply chain? This is a key issue that crosses the boundary between supply chain management and …
