The Impact Of The Options Backdating Scandal On Shareholders, Gennaro Bernile, Gregg Jarrell Mar 2009

The Impact Of The Options Backdating Scandal On Shareholders, Gennaro Bernile, Gregg Jarrell

Research Collection Lee Kong Chian School Of Business

The revelation that scores of firms engaged in the illegal manipulation of stock options’ grant dates (i.e. “backdating”) captured much public attention. The evidence indicates that the consequences stemming from management misconduct and misrepresentation are of first-order importance in this context as shareholders of firms accused of backdating experience large negative, statistically significant abnormal returns. Furthermore, shareholders’ losses are directly related to firms’ likely culpability and the magnitude of the resulting restatements, despite the limited cash flow implications. And, tellingly, the losses are attenuated when tainted management of less successful firms is more likely to be replaced and relatively many …


How To Distinguish Smart Big Moves From Stupid Ones, Paul Strebel, Anne-Valerie Ohlsson-Corboz Mar 2009

How To Distinguish Smart Big Moves From Stupid Ones, Paul Strebel, Anne-Valerie Ohlsson-Corboz

Research Collection Lee Kong Chian School Of Business

When top executives undertake big moves – dramatic shifts in strategic direction – their decisions can make or break a company. This paper aims to offer a methodology for cutting the risks of making a catastrophic misstep. To avoid a corporate disaster and increase the chances of a smart and ultimately successful big move the paper raises six critical questions that must be answered honestly and unequivocally by managers. The research indicates that there are five classic types of big move, each corresponding to a different position on the corporate performance curve: finding a new game; going for growth; getting …


Second Stage Development Of The Integrated Crisis Mapping (Icm) Model In Crisis Communication: Organizational Strategies For Crises That Require High And Low Organizational Engagements, Augustine Pang, Yan Jin, Glen T. Cameron Mar 2009

Second Stage Development Of The Integrated Crisis Mapping (Icm) Model In Crisis Communication: Organizational Strategies For Crises That Require High And Low Organizational Engagements, Augustine Pang, Yan Jin, Glen T. Cameron

Research Collection Lee Kong Chian School Of Business

Extending current theories in crisis communication, the authors have developed a moresystemic approach to understanding the role of emotions. The Integrated Crisis Mapping (ICM)model is based on a public-based, emotion-driven perspective where different crises aremapped on two continua, the organization’s engagement in the crisis and primary public’scoping strategy. This second-stage testing, representing the fourth in the series, found that ontop of discovering anxiety as a possible default emotion that publics feel in crises in an earlierstudy, the default response organizations embroiled in crises involving hostile takeovers,accidents, natural disasters, CEO retirement, rumor, and psychopathic acts, tend to adopt isqualified rhetoric-mix stance …

A Social Relation Aware Routing Protocol For Mobile Ad Hoc Networks, Jisun An, Yangwoo Ko, Dongman Lee Mar 2009

A Social Relation Aware Routing Protocol For Mobile Ad Hoc Networks, Jisun An, Yangwoo Ko, Dongman Lee

Research Collection School Of Computing and Information Systems

In this paper, we propose a social relation aware routing protocol for mobile ad hoc networks, which is designed for content sharing mobile social applications. Since a content can be shared by a group of users who have similar interests, the similarity of users' interests is a good metric to predict who will consume which contents. Shared interests can be exploited in routing and replication of content request and reply to achieve enhanced efficacy in content sharing. Since routing determines which content will be forwarded by whom, a route selected based on similarity of interest increases the utilization of contents …


Server-Assisted Context-Dependent Pervasive Wellness Monitoring, Archan Misra, Ben Falchuk, Shoshana Loeb Mar 2009

Server-Assisted Context-Dependent Pervasive Wellness Monitoring, Archan Misra, Ben Falchuk, Shoshana Loeb

Research Collection School Of Computing and Information Systems

Recent research on remote health monitoring solutions has focused largely on developing context-dependent, streamprocessing capabilities on a personal mobile hub (typically, a cellphone) for energy-efficient transmission of data collected from a set of body-worn medical sensors. In this paper, we argue that commercial deployment of such pervasive wellness monitoring will require the extension of such ‘context dependency’ to the process of data collection (from the sensors to the mobile device) as well. In particular, the utilization of an individuals non-medical activity context, by the cellphone, in coordination with a backend server, is posited to be the key to supporting important …


The Efficiency Of Friendliness: Japanese Corporate Governance Succeeds Again Without Hostile Takeovers, Dan W. Puchniak Mar 2009

The Efficiency Of Friendliness: Japanese Corporate Governance Succeeds Again Without Hostile Takeovers, Dan W. Puchniak

Research Collection Yong Pung How School Of Law

It is widely assumed that hostile takeovers are a prerequisite for an efficient system of corporate governance. This assumption is false. Since the new millennium, Japan has transformed itself from being on the brink of one of the largest economic meltdowns in modern economic history to currently being in the midst of its longest period of postwar economic expansion (2002-2007). This astounding recovery was achieved without a single successful hostile takeover of a major Japanese company. True to its postwar tradition, corporate Japan has successfully restructured through government intervention, bank-driven reallocation of capital, and orchestrated and friendly mergers — the …


Programmable Presence Virtualization For Next-Generation Context-Based Applications, Arup Acharya, Nilanjan Banerjee, Dipanjan Chakraborty, Koustuv Dasgupta, Archan Misra, Shachi Sharma, Xiping Wang, Charles P. Wright Mar 2009

Programmable Presence Virtualization For Next-Generation Context-Based Applications, Arup Acharya, Nilanjan Banerjee, Dipanjan Chakraborty, Koustuv Dasgupta, Archan Misra, Shachi Sharma, Xiping Wang, Charles P. Wright

Research Collection School Of Computing and Information Systems

Presence, broadly defined as an event publish-notification infrastructure for converged applications, has emerged as a key mechanism for collecting and disseminating context attributes for next-generation services in both enterprise and provider domains. Current presence-based solutions and products lack in the ability to a) support flexible user-defined queries over dynamic presence data and b) derive composite presence from multiple provider domains. Accordingly, current uses of context are limited to individual domains/organizations and do not provide a programmable mechanism for rapid creation of context-aware services. This paper describes a presence virtualization architecture, where a virtualized presence server receives customizable queries from multiple …


Multiracial Identity Integration: Perceptions Of Conflict And Distance Among Multiracial Individuals, Chi-Ying Cheng, Fiona Lee Mar 2009

Multiracial Identity Integration: Perceptions Of Conflict And Distance Among Multiracial Individuals, Chi-Ying Cheng, Fiona Lee

Research Collection School of Social Sciences

This article examines how multiracial individuals negotiate their different and sometimes conflicting racial identities. Drawing from previous work on bicultural identity integration (see Benet-Martinez and Haritatos, 2005), we proposed a new construct, multiracial identity integration (MII), to measure individual differences in perceptions of compatibility between multiple racial identities. We found that MII is composed of two independent subscales: that describes whether different racial identities are perceived as disparate, and that describes whether different racial identities are perceived as in conflict. We also found that recalling positive multiracial experiences increased MII, while recalling negative multiracial experiences decreased MII. These findings have …


Visual Word Proximity And Linguistics For Semantic Video Indexing And Near-Duplicate Retrieval, Yu-Gang Jiang, Chong-Wah Ngo Mar 2009

Visual Word Proximity And Linguistics For Semantic Video Indexing And Near-Duplicate Retrieval, Yu-Gang Jiang, Chong-Wah Ngo

Research Collection School Of Computing and Information Systems

Bag-of-visual-words (BoW) has recently become a popular representation to describe video and image content. Most existing approaches, nevertheless, neglect inter-word relatedness and measure similarity by bin-to-bin comparison of visual words in histograms. In this paper, we explore the linguistic and ontological aspects of visual words for video analysis. Two approaches, soft-weighting and constraint-based earth mover’s distance (CEMD), are proposed to model different aspects of visual word linguistics and proximity. In soft-weighting, visual words are cleverly weighted such that the linguistic meaning of words is taken into account for bin-to-bin histogram comparison. In CEMD, a cross-bin matching algorithm is formulated such …


Continuous Visible Nearest Neighbour Queries, Yunjun Gao, Baihua Zheng, Wang-Chien Lee, Gencai Chen Mar 2009

Continuous Visible Nearest Neighbour Queries, Yunjun Gao, Baihua Zheng, Wang-Chien Lee, Gencai Chen

Research Collection School Of Computing and Information Systems

In this paper, we identify and solve a new type of spatial queries, called continuous visible nearest neighbor (CVNN) search. Given a data set P, an obstacle set O, and a query line segment q, a CVNN query returns a set of (p, R) tuples such that p ? P is the nearest neighbor (NN) to every point r along the interval R ? q as well as p is visible to r. Note that p may be NULL, meaning that all points in P are invisible to all points in R, due to the obstruction of some obstacles in …


Web Query Recommendation Via Sequential Query Prediction, Qi He, Daxin Jiang, Zhen Liao, Steven C. H. Hoi, Kuiyu Chang, Ee Peng Lim, Hang Li Mar 2009

Web Query Recommendation Via Sequential Query Prediction, Qi He, Daxin Jiang, Zhen Liao, Steven C. H. Hoi, Kuiyu Chang, Ee Peng Lim, Hang Li

Research Collection School Of Computing and Information Systems

Web query recommendation has long been considered a key feature of search engines. Building a good Web query recommendation system, however, is very difficult due to the fundamental challenge of predicting users' search intent, especially given the limited user context information. In this paper, we propose a novel "sequential query prediction" approach that tries to grasp a user's search intent based on his/her past query sequence and its resemblance to historical query sequence models mined from massive search engine logs. Different query sequence models were examined, including the naive variable length N-gram model, Variable Memory Markov (VMM) model, and our …

We are in dire straits - no doubt about it. Our banks and financial edifices are collapsing. Those left standing also look shaky. The financial industry as a whole is battling to survive. And, as its frontline warriors, we will bear the brunt of the blood- bath sure to ensue any minute now. A good opportunity to play solitaire?


Final Stage Development Of The Integrated Crisis Mapping (Icm) Model In Crisis Communication: The Myth Of Low Engagement In Crisis, A. Pang, Yan Jin, Glen T. Cameron Mar 2009

Final Stage Development Of The Integrated Crisis Mapping (Icm) Model In Crisis Communication: The Myth Of Low Engagement In Crisis, A. Pang, Yan Jin, Glen T. Cameron

Research Collection Lee Kong Chian School Of Business

Extending current theories in crisis communication, the authors have developed a more systemic approach to understanding the role of emotions. The Integrated Crisis Mapping (ICM) model is based on a public-based, emotion-driven perspective where different crises are mapped on two continua, the organization’s engagement in the crisis and primary public’s coping strategy. This final-stage testing, representing the sixth in the series, found that even though organizations need not be highly engaged in crises relating to human resource, transport failure and security issues, they were galvanized to engage in action-based stance by situational factors like external threats. The fact that the …


Pat: Towards Flexible Verification Under Fairness, Jun Sun, Yang Liu, Jin Song Dong, Jun Pang Feb 2009

Pat: Towards Flexible Verification Under Fairness, Jun Sun, Yang Liu, Jin Song Dong, Jun Pang

Research Collection School Of Computing and Information Systems

Recent development on distributed systems has shown that a variety of fairness constraints (some of which are only recently defined) play vital roles in designing self-stabilizing population protocols. Current practice of system analysis is, however, deficient under fairness. In this work, we present PAT, a toolkit for flexible and efficient system analysis under fairness. A unified algorithm is proposed to model check systems with a variety of fairness effectively in two different settings. Empirical evaluation shows that PAT complements existing model checkers in terms of fairness. We report that previously unknown bugs have been revealed using PAT against systems functioning …

Managing Information Technology Project Escalation And De-Escalation: An Approach-Avoidance Perspective, Gary Pan, Shan Ling Pan, Michael Newman Feb 2009

Managing Information Technology Project Escalation And De-Escalation: An Approach-Avoidance Perspective, Gary Pan, Shan Ling Pan, Michael Newman

Research Collection School Of Accountancy

This paper presents an integrated theoretical process model for identifying , describing, and analyzing the complex escalation and de-escalation phenomena in software development projects. The approach-avoidance theory is used to integrate core elements of various escalation theories into a holistic, explanatory framework for the two phenomena. We use a process model to identify antecedent conditions, sequences of events, critical incidents, and outcomes over the course of a project. The analysis also operates at multiple levels: project, work, and environment. This highlights the recursive interactions between project, organizational work activities, and their contexts during the software project development process. By conceiving …


Bmq-Processor: A High-Performance Border Crossing Event Detection Framework For Large-Scale Monitoring Applications, Jinwon Lee, Seungwoo Kang, Youngki Lee, Sangjeong Lee, Junehwa Song Feb 2009

Bmq-Processor: A High-Performance Border Crossing Event Detection Framework For Large-Scale Monitoring Applications, Jinwon Lee, Seungwoo Kang, Youngki Lee, Sangjeong Lee, Junehwa Song

Research Collection School Of Computing and Information Systems

In this paper, we present BMQ-Processor, a high-performance Border-Crossing Event (BCE) detection framework for large-scale monitoring applications. We first characterize a new query semantics, namely, Border Monitoring Query (BMQ), which is useful for BCE detection in many monitoring applications. It monitors the values of data streams and reports them only when data streams cross the borders of its range. We then propose BMQ-Processor to efficiently handle a large number of BMQs over a high volume of data streams. BMQ-Processor efficiently processes BMQs in a shared and incremental manner. It develops and operates over a novel stateful query index, achieving a …

Desert Heat Island Study In Winter By Mobile Transect And Remote Sensing Techniques, Chen-Yi Sun, Anthony J. Brazel, Winston T. L. Chow, Brent C. Hedquist, Lela Prashad

Research Collection School of Social Sciences

A familiar problem in urban environments is the urban heat island (UHI), which potentially increases air conditioning demands, raise pollution levels, and could modify precipitation patterns. The magnitude and pattern of UHI effects have been major concerns of a lot of urban environment studies. Typically, research on UHI magnitudes in arid regions (such as Phoenix, AZ, USA) focuses on summer. UHI magnitudes in Phoenix (more than three million population) attain values in excess of 5°C. This study investigated the early winter period—a time when summer potential evapotranspiration >250 mm has diminished to 8.0°C, comparable to summertime UHI conditions. Through analysis …


Scale-Rotation Invariant Pattern Entropy For Keypoint-Based Near-Duplicate Detection, Wan-Lei Zhao, Chong-Wah Ngo Feb 2009

Scale-Rotation Invariant Pattern Entropy For Keypoint-Based Near-Duplicate Detection, Wan-Lei Zhao, Chong-Wah Ngo

Research Collection School Of Computing and Information Systems

Near-duplicate (ND) detection appears as a timely issue recently, being regarded as a powerful tool for various emerging applications. In the Web 2.0 environment particularly, the identification of near-duplicates enables the tasks such as copyright enforcement, news topic tracking, image and video search. In this paper, we describe an algorithm, namely Scale-Rotation invariant Pattern Entropy (SR-PE), for the detection of near-duplicates in large-scale video corpus. SR-PE is a novel pattern evaluation technique capable of measuring the spatial regularity of matching patterns formed by local keypoints. More importantly, the coherency of patterns and the perception of visual similarity, under the scenario …


Faith And Fortune In The Post-Colonial Classroom, Stefano Harney, Stephen Linstead Feb 2009

Faith And Fortune In The Post-Colonial Classroom, Stefano Harney, Stephen Linstead

Research Collection Lee Kong Chian School Of Business

The place of spirituality, religion, faith and cynicism in management education has received increasing attention in the past decade. From the point of view of teaching focused on critical engagement with practice, they are sometimes viewed as obstacles to practice. In this article we use resources from post-colonial thought and global critical race theory to suggest the opposite—that faith and cynicism can be understood as forms of critique issuing from the student perspective and that we might learn from these critiques as a way to reconfigure persistent dilemmas in the critique of the Enlightenment that trouble critical management approaches. We …


A Hybrid Scatter Search For The Discrete Time/Resource Trade-Off Problem In Project Scheduling, Mohammad Ranbar, Bert De Reyck, Fereydoon Kianfar Feb 2009

A Hybrid Scatter Search For The Discrete Time/Resource Trade-Off Problem In Project Scheduling, Mohammad Ranbar, Bert De Reyck, Fereydoon Kianfar

Research Collection Lee Kong Chian School Of Business

We develop a heuristic procedure for solving the discrete time/resource trade-off problem in the field of project scheduling. In this problem, a project contains activities interrelated by finish-start-type precedence constraints with a time lag of zero, which require one or more constrained renewable resources. Each activity has a specified work content and can be performed in different modes, i.e. with different durations and resource requirements, as long as the required work content is met. The objective is to schedule each activity in one of its modes in order to minimize the project makespan. We use a scatter search algorithm to …


Analyzing And Forecasting Business Cycles In A Small Open Economy: A Dynamic Factor Model For Singapore, Hwee Kwan Chow, Keen Meng Choy Feb 2009

Analyzing And Forecasting Business Cycles In A Small Open Economy: A Dynamic Factor Model For Singapore, Hwee Kwan Chow, Keen Meng Choy

Research Collection School Of Economics

A dynamic factor model is applied to a large panel dataset of Singapore’s macroeconomic variables and global economic indicators with the initial objective of analyzing business cycles in a small open economy. The empirical results suggest that four common factors are present in the quarterly time series, which can broadly be interpreted as world, regional, electronics and domestic economic cycles. The estimated factor model explains well the observed fluctuations in real economic activity and price inflation, leading us to use it in forecasting Singapore’s business cycles. We find that the forecasts generated by the factors are generally more accurate than …


Real-Time Near-Duplicate Elimination For Web Video Search With Content And Context, Xiao Wu, Chong-Wah Ngo, Alexander G. Hauptmann Feb 2009

Real-Time Near-Duplicate Elimination For Web Video Search With Content And Context, Xiao Wu, Chong-Wah Ngo, Alexander G. Hauptmann

Research Collection School Of Computing and Information Systems

With the exponential growth of social media, there exist huge numbers of near-duplicate web videos, ranging from simple formatting to complex mixture of different editing effects. In addition to the abundant video content, the social web provides rich sets of context information associated with web videos, such as thumbnail image, time duration and so on. At the same time, the popularity of Web 2.0 demands for timely response to user queries. To balance the speed and accuracy aspects, in this paper, we combine the contextual information from time duration, number of views, and thumbnail images with the content analysis derived …


Stochastic Modeling Western Paintings For Effective Classification, Jialie Shen Feb 2009

Stochastic Modeling Western Paintings For Effective Classification, Jialie Shen

Research Collection School Of Computing and Information Systems

As one of the most important cultural heritages, classical western paintings have always played a special role in human live and been applied for many different purposes. While image classification is the subject of a plethora of related publications, relatively little attention has been paid to automatic categorization of western classical paintings which could be a key technique of modern digital library, museums and art galleries. This paper studies automatic classification on large western painting image collection. We propose a novel framework to support automatic classification on large western painting image collections. With this framework, multiple visual features can be …
