Font Size: Make Font Size Smaller Make Font Size Default Make Font Size Larger Exploiting Coordination Locales In Distributed Pomdps Via Social Model Shaping, Pradeep Varakantham, Jun Young Kwak, Matthew Taylor, Janusz Marecki, Paul Scerri, Milind Tambe

Research Collection School Of Computing and Information Systems

Distributed POMDPs provide an expressive framework for modeling multiagent collaboration problems, but NEXPComplete complexity hinders their scalability and application in real-world domains. This paper introduces a subclass of distributed POMDPs, and TREMOR, an algorithm to solve such distributed POMDPs. The primary novelty of TREMOR is that agents plan individually with a single agent POMDP solver and use social model shaping to implicitly coordinate with other agents. Experiments demonstrate that TREMOR can provide solutions orders of magnitude faster than existing algorithms while achieving comparable, or even superior, solution quality.


Aiming For “Brand Bonuses” In Times Of Budget Cuts, Knowledge@Smu Aug 2009

Aiming For “Brand Bonuses” In Times Of Budget Cuts, Knowledge@Smu

Knowledge@SMU

Branding, perceived by the bean-counters as an expense item, is always among the first to go during recessions. In its place are price cuts and price promotions aimed at delivering value to customers. The common (and predictable) belief is to stimulate demand quickly, so as to sustain production and operations during the trying times. After all, brand equity cannot possibly help close a sale or bring in the cash –- or can it? To answer this question, SMU’s Provost, Rajendra K. Srivastava, examined the financial performance of brands during a downturn in a hunt for the elusive “brand bonus”.


Beyond Fakirs And Call Centres: Lessons From India’S Global Powerhouses, Knowledge@Smu Aug 2009

Beyond Fakirs And Call Centres: Lessons From India’S Global Powerhouses, Knowledge@Smu

Knowledge@SMU

Forget the stereotype of the Indian accountant, IT manager or call centre operator. Instead, think savvy bigwigs with hungry appetites for all things foreign. Some of the world’s largest and most successful corporate acquisitions over the last 15 years have been carried out by conglomerates bearing the Indian flag. Tata, Mittal, Bharat Forge and Infosys are but just the more prominent names. Many others are emerging. What can we learn from these powerhouses and what makes them tick?


Shopping With Elephants: Coming To Terms With Nepotism In The Retail Space, Knowledge@Smu Aug 2009

Shopping With Elephants: Coming To Terms With Nepotism In The Retail Space, Knowledge@Smu

Knowledge@SMU

Nepotism, favouritism and discrimination: issues that exist not only in business and politics, but also, in shopping malls! Research has shown that customers will likely receive benefits and superior service when they demonstrate a common “bond” with the people who serve them. Perks include free products, upgrades, queue-jumps and other value-adds, such as staff recommendations and extra attentive service. While such “allowances” create wonderful retail experiences for customers who receive it, is it fair for those who don’t?

The Importance Of Being Earnest… In Cyberspace, Knowledge@Smu

Knowledge@SMU

Community websites are increasingly viewed as treasure troves of opinions, from restaurant service to hotel accommodations, from mobile phone reviews to reliability ratings of an online auctioneer. An underlying factor behind the success of such websites is the implicit trust between users – to offer unbiased, accurate views. Consequently, a trustworthy online community puts users at ease to make decisions and perform transactions confidently. So web administrators would do well to maintain a trusting online community, if only to keep the cash tills a-ringing. But is it possible to measure or monitor something as unquantifiable as inter-user trust?


Plus Ça Change: Innovation And The Spirit Of Enterprise In Tocqueville’S America, Christine Dunn Henderson Aug 2009

Plus Ça Change: Innovation And The Spirit Of Enterprise In Tocqueville’S America, Christine Dunn Henderson

Research Collection School of Social Sciences

Tocqueville describes the spirit of enterprise—along with the taste for material well-being—as “the distinctive characteristic” of the American people. This paper explores the American spirit of innovation and enterprise, beginning with the centrality of this spirit for America's commercial greatness. Tocqueville observes that the taste for innovation is a part of American national character, and its roots can be traced to the equality of conditions which characterizes democratic life. But the same equality of conditions which promotes the spirit of innovation also can also threaten it, for equality of conditions paradoxically encourages individuals both to rely upon their own judgment …

The Influence Of Work Personality On Job Satisfaction: Incremental Validity And Mediation Effects, Daniel Heller, D. Lance Ferris, Douglas Brown, David Watson Aug 2009

The Influence Of Work Personality On Job Satisfaction: Incremental Validity And Mediation Effects, Daniel Heller, D. Lance Ferris, Douglas Brown, David Watson

Research Collection Lee Kong Chian School Of Business

Drawing from recent developments regarding the contextual nature of personality (e.g., D. Wood & B. W. Roberts, 2006), we conducted 2 studies (1 cross-sectional and 1 longitudinal over 1 year) to examine the validity of work personality in predicting job satisfaction and its mediation of the effect of global personality on job satisfaction. Study 1 showed that (a) individuals vary systematically in their personality between roles— they were significantly more conscientious and open to experience and less extraverted at work compared to at home; (b) work personality was a better predictor of job satisfaction than both global personality and home …

Design/methodology/approach – The meta-analysis method is used to combine different data in various studies of one topic into one comprehensive study. More than 30 crises are meta-analyzed. Findings – The CEO needs to step up to revise earlier statements or when the integrity …


Evaluating Straddle Carrier Deployment Policies: A Simulation Study For The Piraeus Container Terminal, Eleni Hadjiconstantinou, Nang Laik Ma Aug 2009

Evaluating Straddle Carrier Deployment Policies: A Simulation Study For The Piraeus Container Terminal, Eleni Hadjiconstantinou, Nang Laik Ma

Research Collection School Of Computing and Information Systems

Most container terminals in the world today are operating up to their capacities. In this paper, we have developed a decision support system to optimise yard operations by considering all container flows (import, export and transshipment) through the yard with the view to improving the terminal performance and efficiency. In another paper, we proposed an optimisation model that determines optimal container locations and straddle carrier (SC) movements with the objective of minimising the overall storage and handling cost of containers. In this paper, a discrete event simulation tool for container terminal operations has been developed with three objectives: (i) to …


Why Might Some Employees Sabotage Their Companies?, Knowledge@Smu Jul 2009

Why Might Some Employees Sabotage Their Companies?, Knowledge@Smu

Knowledge@SMU

The abuse of organisational resources, lying to colleagues, mishandling of confidential data, blackmail, etc - deviant behaviour in the workplace is not just a nuisance, but also a crippling and costly affair, easily reaching billions annually. As it is, business leaders are already saddled with enough worries over the market environment. Tackling deviant behaviour is an extra human resource challenge that most would prefer to go without. Lance Ferris, an organisational behaviour and human resources professor at Singapore Management University, looks at what causes such behaviour: self-esteem, and how managers can address this issue.


Bringing The Power Of Information To Life – The Case Of Emc Corporation, Knowledge@Smu Jul 2009

Bringing The Power Of Information To Life – The Case Of Emc Corporation, Knowledge@Smu

Knowledge@SMU

Technology, markets and customer needs are changing. EMC Corporation, which started as a memory board maker thirty years ago, has been changing along. More well-known in the technology industry for its range of hardware used to store data, the company now positions itself as an “information storage vendor”, where software and services plays a greater role. Along with this repositioning, the company is actively managing what the EMC brand stands for, says EMC’s Steven Leonard.

Think Outside Your Box: Enhancing Creativity Through Multicultural Interactions, Knowledge@Smu Jul 2009

Think Outside Your Box: Enhancing Creativity Through Multicultural Interactions, Knowledge@Smu

Knowledge@SMU

Creative ideas are often the result of two or more seemingly non-overlapping concepts. The more we expose ourselves to diverse experiences, the more likely we might be to sample from a richer pool of ideas, thereby facilitating our creativity, and by extension for some, organisational innovation. This is because experience lowers our resistance and increases our readiness to sample foreign concepts. Angela Leung, an assistant professor of psychology at Singapore Management University, notes that while ideas from differing cultural experiences can be recruited as intellectual resources, several factors inhibit our ability to draw on these experiences, thus impeding our creative …


Ownership, Institutions, And Capital Structure: Evidence From China, Kai Li, Heng Yue, Longkai Zhao Jul 2009

Ownership, Institutions, And Capital Structure: Evidence From China, Kai Li, Heng Yue, Longkai Zhao

Research Collection School Of Accountancy

We employ a unique data set to explore the role of ownership structure and institutional development in debt financing of non-publicly traded Chinese firms. We show that state ownership is positively associated with leverage and firms’ access to long-term debt, while foreign ownership is negatively associated with all measures of leverage. Surprisingly, firms in better developed regions are associated with reduced access to long-term debt, suggesting the availability of alternative financing channels and the tightening of the lending standards under the on-going banking reform. The combination of ownership structures and institutions explains up to 6% of the total variation in …


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 Jul 2009

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 …


Who I Am And How I Think: The Impact Of Self-Construal On The Roles Of Internal And External Reference Prices In Price Evaluations, Yi, Cathy Chen Jul 2009

Who I Am And How I Think: The Impact Of Self-Construal On The Roles Of Internal And External Reference Prices In Price Evaluations, Yi, Cathy Chen

Research Collection Lee Kong Chian School Of Business

Drawing from self-construal studies on cognitive styles as well as reference price literature, this research investigates the impact of independent versus interdependent self-construal on consumers' use of internal reference prices (IRPs) and external reference prices (ERPs) during price evaluations. Three experiments reveal that IRPs have a larger impact on price evaluations for participants who are primed with an independent (vs. interdependent) self-construal, whereas ERPs have a larger impact for participants who are primed with an interdependent (vs. independent) self-construal. The differential impact of self-construal on the use of IRPs and ERPs seems to be mediated by a generalized, perceived sense …


Myopic Regret Avoidance: Feedback Avoidance And Learning In Repeated Decision Making, Jochen Reb, Terry Connolly Jul 2009

Myopic Regret Avoidance: Feedback Avoidance And Learning In Repeated Decision Making, Jochen Reb, Terry Connolly

Research Collection Lee Kong Chian School Of Business

Decision makers can become trapped by myopic regret avoidance in which rejecting feedback to avoid short-term outcome regret (regret associated with counterfactual outcome comparisons) leads to reduced learning and greater long-term regret over continuing poor decisions. In a series of laboratory experiments involving repeated choices among uncertain monetary prospects, participants primed with outcome regret tended to decline feedback, learned the task slowly or not at all, and performed poorly. This pattern was reversed when decision makers were primed with self-blame regret (regret over an unjustified decision). Further, in a final experiment in which task learning was unnecessary, feedback was more …


From Crisis To Opportunity: Environmental Jolt, Corporate Acquisitions, And Firm Performance, William P. Wan, Daphne W. Yiu Jul 2009

From Crisis To Opportunity: Environmental Jolt, Corporate Acquisitions, And Firm Performance, William P. Wan, Daphne W. Yiu

Research Collection Lee Kong Chian School Of Business

This study incorporates the external environmental context into the study of corporate acquisitions by examining the performance implications of corporate acquisitions during an environmental jolt that alters the levels of environmental munificence. We posit that compared to the periods before and after an environmental jolt, corporate acquisitions during a jolt would be positively related to firm performance. Furthermore, we suggest that organizational slack would improve firm performance and accentuate the positive relationship between corporate acquisitions and firm performance during an environmental jolt; however, it would have negative impact on firm performance and make the acquisition-performance relationship more negative before and …


Academics Or Entrepreneurs? Investigating Role Identity Modification Of University Scientists Involved In Commercialization Activity, Sanjay Jain, Gerard George, Mark Maltarich Jul 2009

Academics Or Entrepreneurs? Investigating Role Identity Modification Of University Scientists Involved In Commercialization Activity, Sanjay Jain, Gerard George, Mark Maltarich

Research Collection Lee Kong Chian School Of Business

Establishing the microfoundations of academic entrepreneurship requires closer scrutiny of a key actor contributing to this phenomenon—the university scientist. We investigate the sense-making that scientists engage in as part of their participation in technology transfer and postulate that this process involves a potential modification in their role identity. We analyzed more than 70 h of interview data at a premier U.S. public research university. We observe that scientists invoke rationales for involvement that are congruent with their academic role identity. They typically adopt a hybrid role identity that comprises a focal academic self and a secondary commercial persona. We delineate …


The Effects Of Response Instructions On Situational Judgment Test Performance And Validity In A High-Stakes Context, Filip Lievens, Paul R. Sackett, Tine Buyse Jul 2009

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 …


Ktr: An Efficient Key Management Scheme For Secure Data Access Control In Wireless Broadcast Services Recovery, Qijun Gu, Peng Liu, Wang-Chien Lee, Chao-Hsien Chu Jul 2009

Ktr: An Efficient Key Management Scheme For Secure Data Access Control In Wireless Broadcast Services Recovery, Qijun Gu, Peng Liu, Wang-Chien Lee, Chao-Hsien Chu

Research Collection School Of Computing and Information Systems

Wireless broadcast is an effective approach for disseminating data to a number of users. To provide secure access to data in wireless broadcast services, symmetric-key-based encryption is used to ensure that only users who own the valid keys can decrypt the data. With regard to various subscriptions, an efficient key management for distributing and changing keys is in great demand for access control in broadcast services. In this paper, we propose an efficient key management scheme, namely, key tree reuse (KTR), to handle key distribution with regard to complex subscription options and user activities. KTR has the following advantages. First, …

An Agent-Based Commodity Trading Simulation, Shih-Fen Cheng, Yee Pin Lim

Research Collection School Of Computing and Information Systems

In this paper, an event-centric commodity trading simulation powered by the multiagent framework is presented. The purpose of this simulation platform is for training novice traders. The simulation is progressed by announcing news events that affect various aspects of the commodity supply chain. Upon receiving these events, market agents that play the roles of producers, consumers, and speculators would adjust their views on the market and act accordingly. Their actions would be based on their roles and also their private information, and collectively they shape the market dynamics. This simulation has been effectively deployed for several training sessions. We will …


How Liquid Are Liquid Hedge Funds?, Melvyn Teo Jun 2009

How Liquid Are Liquid Hedge Funds?, Melvyn Teo

Research Collection BNP Paribas Hedge Fund Centre

Many hedge funds impose minimal share restrictions and allow investors to redeem on a monthly basis or better. We find that there is significant variation in the liquidity risk exposure of these “liquid” funds. Within this group of funds, those that embrace liquidity risk outperform those that eschew liquidity risk by 4.86 percent per year. As a consequence of the liquidity risk exposure, funds experiencing outflows subsequently earn lower returns than funds receiving inflows. The effects of flows are more pronounced for funds employing leverage, for funds with high liquidity risk exposure, and during a liquidity crunch. These results underscore …

Branding For Airliners In A Web 2.0 World, Knowledge@Smu

Knowledge@SMU

In the world of digital social networking, consumers can influence how brands are perceived. Airliners, often besieged with challenges in areas such as service, security, regulations, oil prices, make convenient targets for online critics. While many uncertainties exist in the business of running airliners, one certainty brought about by Web 2.0 is that customer experiences, good and bad, will be reported. That is why Shashank Nigam, CEO of SimpliFlying, an airline brand consultancy, believes that brands within the airline sector need to respond quickly.

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.

Consumer Technology: Professional Versus 'Octopus' Peripherals, Knowledge@Smu

Knowledge@SMU

Convergence is a popular term in consumer electronics. In recent years, a number of gadgets have evolved to take on different functions, as manufacturers try to out-do one another. Printers are now expected to scan and fax. Mobile phones are moonlighting as cameras. Mp3 players have become mini-television sets. In a paper about technological convergence, SMU marketing professors, Jin Han and Seh-Woong Chung, explore how consumers are really taking to such multi-purpose machines.


Why Should Investors Stay Positive On The Asian Real Estate Markets?, Knowledge@Smu Jun 2009

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?


Deterministic Chaos In A Model Of Discrete Manufacturing, John J. Iii Bartholdi, Donald D. Eisenstein, Yun Fong Lim Jun 2009

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.


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 Jun 2009

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.
