Attacks And Defence On Android Free Floating Windows, Lingyun Ying, Yao Cheng, Yemian Lu, Yacong Gu, Purui Su, Dengguo Feng

Research Collection School Of Computing and Information Systems

Nowadays, the popular Android is so closely involved in people's daily lives that people rely on Android to perform critical operations and trust Android with sensitive information. It is of great importance to guarantee the usability and security of Android which, however, is such a huge system that a potential threat may arise from any part of it. In this paper, we focus on the Free Floating window (FF window) which is a category of windows that can appear freely above any other applications. It can share the screen space with other FF windows, dialogs, and activities. An FF window …

Consequences To Directors Of Shareholder Activism, Sa-Pyung Sean Shin, Sa-Pyung Sean Shin, Suraj Srinivasan May 2016

Consequences To Directors Of Shareholder Activism, Sa-Pyung Sean Shin, Sa-Pyung Sean Shin, Suraj Srinivasan

Research Collection School Of Accountancy

Using a comprehensive sample for 2004–2012, we examine the impact of shareholder activist campaigns on the careers of directors of targeted firms. We find that activism is associated with directors being almost twice as likely to leave—and performance-sensitivity of turnover being higher over the subsequent two-year period. Our evidence suggests that director turnover occurs even without shareholder activists engaging in, let alone winning, proxy contests and, in contrast to most prior research, director election results matter. Overall, our evidence suggests that shareholder activism, even in the absence of proxy fights, is associated with greater accountability for independent directors.

The Downside Of The Network Ties Between Ceo/Cfos And Auditors Through External Directorships: Evidence From Auditor Selection And Subsequent Audit Quality, Jaeyoon Yu, Byungjin Kwak, Myung Seok Park, Yoonseok Zang May 2016

The Downside Of The Network Ties Between Ceo/Cfos And Auditors Through External Directorships: Evidence From Auditor Selection And Subsequent Audit Quality, Jaeyoon Yu, Byungjin Kwak, Myung Seok Park, Yoonseok Zang

Research Collection School Of Accountancy

This study examines whether the professional ties of Chief Executive Officers/Chief Financial Officers (CEO/CFOs) to auditors through external directorships affect auditor selection and subsequent audit quality. Professional ties to auditors arise when the CEO/CFO of a firm (referred to as the home firm) serves as an outside director of another firm that hires an auditor (a connected auditor). Using a sample of firms with auditor switches over the period 2003-2012, we find that home firms are more likely to appoint connected auditors. Furthermore, utilizing a difference-in-differences approach, we find that home firms appointing connected auditors experience a significant decline in …

Why Hedge? Extent, Nature, And Determinants Of Derivative Usage In U.S. Municipalities, Saleha Khumawala, Ranasinghe, Tharindra, Claire J. Yan May 2016

Why Hedge? Extent, Nature, And Determinants Of Derivative Usage In U.S. Municipalities, Saleha Khumawala, Ranasinghe, Tharindra, Claire J. Yan

Research Collection School Of Accountancy

Using a hand-collected dataset of over 300 observations of large U.S. cities and counties, this paper investigates the extent, nature and determinants of derivatives usage in the municipal sector. Over half of our sample entities engage in derivative transactions and a vast majority of these transactions are intended to manage interest rate risk. Swaps, by far, are the most popular derivative instrument. In terms of the determinants of derivative usage, we find that the propensity to use derivatives as well as the extent of derivative usage is higher for municipalities that are larger and more financially constrained. We do not …

Financial Health And Corporate Performance: A Comparison Of Manufacturing Companies In China And India, See Liang Foo, Shaakalya Pathak May 2016

Financial Health And Corporate Performance: A Comparison Of Manufacturing Companies In China And India, See Liang Foo, Shaakalya Pathak

Research Collection School Of Accountancy

The People’s Republic of China (China) and India are two leading economies in Asia Pacific. This study examines the relationship between the financial health, as measured by the Altman Z-Score, and corporate performance, as measured by the Return on Equity (ROE), of listed manufacturing companies in these two markets. A linear regression was conducted between these variables to determine the magnitude and direction of their relationships. The trends of Z-Scores over a fourteen-year period are also analysed. The analysis covers the period from 2000 to 2013 (inclusive) and yielded a statistically positive correlation between ROE and the Z-Score for both …

Mandatory Financial Reporting And Voluntary Disclosure: The Effect Of Mandatory Ifrs Adoption On Management Forecasts, Xi Li, Holly I. Yang May 2016

Mandatory Financial Reporting And Voluntary Disclosure: The Effect Of Mandatory Ifrs Adoption On Management Forecasts, Xi Li, Holly I. Yang

Research Collection School Of Accountancy

This study examines the effect of the mandatory adoption of International Financial Reporting Standards (IFRS) on voluntary disclosure. Using a difference-in-difference analysis, we document a significant increase in the likelihood and frequency of management earnings forecasts following mandatory IFRS adoption, consistent with the notion that IFRS adoption alters firms' disclosure incentives in response to increased capital-market demand. We find the increase to be larger among firms domiciled in code-law countries, suggesting a catching-up effect among firms facing low disclosure incentives pre-adoption. We then propose and test three channels through which IFRS adoption could alter firms' disclosure incentives: improved earnings quality, …

Price Discovery Of Index Futures Across Markets, Jerry X. Cao, Xiaoming Wang, Nelson Yap, Sili Zhou May 2016

Price Discovery Of Index Futures Across Markets, Jerry X. Cao, Xiaoming Wang, Nelson Yap, Sili Zhou

Research Collection Lee Kong Chian School Of Business

The trading of foreign index futures by the Singapore Exchange (SGX) offers an ideal opportunity to study price discovery and information of trading across different markets. We examine four popular indices - Nikkei 225 Index, MSCI Taiwan Index, CNX Nifty Index and the FTSE China A50 Index traded in SGX and compare them with their home market trading. In contrary to standard theory and evidence, we show that smaller bid-ask spread, lower minimum lots and cheaper transaction cost do not necessary improve information efficiency. These results may shed some light on the usefulness of the role of an international financial …

The Microstructure Behavior Of Sgx Nikkei 225 Index Futures Resulting From Component Changes Of The Underlying Cash Market Index, Charlie Charoenwong, David K. Ding, Vasan Siraprapasiri May 2016

The Microstructure Behavior Of Sgx Nikkei 225 Index Futures Resulting From Component Changes Of The Underlying Cash Market Index, Charlie Charoenwong, David K. Ding, Vasan Siraprapasiri

Research Collection Lee Kong Chian School Of Business

We study the effect of changes involving component stocks of the Nikkei 225 stock index on the behavior of the Nikkei 225 index futures. Specifically, we examine the effects of component changes of the Nikkei 225 on the volume, returns, volatility, and bid-ask spreads (BAS) on its corresponding futures contract traded on the Singapore Exchange (SGX). We find that trading volume increases and the bid-ask spread decreases but there is no significant change in the returns of the SGX Nikkei 225 index futures after a component change takes place. This does not support the Price Pressure Hypothesis, which states that …

Does Africa Need An "African" Management Education Model?, Howard Thomas, Lee, Michelle P., Lynne Thomas, Alexander Wilson May 2016

Does Africa Need An "African" Management Education Model?, Howard Thomas, Lee, Michelle P., Lynne Thomas, Alexander Wilson

Research Collection Lee Kong Chian School Of Business

The African approach to management education has been shaped by a range of environmental, cultural, contextual and regional characteristics. Africa is by any measure a massive, multi-cultural, multi-lingual continent offering the promise of significant economic growth in the longer term. The environment is characterised by volatility, uncertainty, complexity, ambiguity and, often, disruptive change. Despite this, some African states have tried to adapt and formulate a range of strategies for economic growth management and the development of international and inter-regional trading opportunities arising from globalisation. Existing evidence suggests that African management educators have tried to adopt a pragmatic perspective that emphasises …

A Horizon Decomposition Approach For The Capacitated Lot-Sizing Problem With Setup Times, Ioannis Fragkos, Zeger Degraeve, Bert De Reyck May 2016

A Horizon Decomposition Approach For The Capacitated Lot-Sizing Problem With Setup Times, Ioannis Fragkos, Zeger Degraeve, Bert De Reyck

Research Collection Lee Kong Chian School Of Business

We introduce horizon decomposition in the context of Dantzig-Wolfe decomposition, and apply it to the capacitated lot-sizing problem with setup times. We partition the problem horizon in contiguous overlapping intervals and create subproblems identical to the original problem, but of smaller size. The user has the flexibility to regulate the size of the master problem and the subproblem via two scalar parameters. We investigate empirically which parameter configurations are efficient, and assess their robustness at different problem classes. Our branch-and-price algorithm outperforms state-of-the-art branch-and-cut solvers when tested to a new data set of challenging instances that we generated. Our methodology …

A One Health Message About Bats Increases Intentions To Follow Public Health Guidance On Bat Rabies, Hang Lu, Katherine A. Mccomas, Danielle E. Buttke, Sungjong Roh, Margaret A. Wild May 2016

A One Health Message About Bats Increases Intentions To Follow Public Health Guidance On Bat Rabies, Hang Lu, Katherine A. Mccomas, Danielle E. Buttke, Sungjong Roh, Margaret A. Wild

Research Collection Lee Kong Chian School Of Business

Since 1960, bat rabies variants have become the greatest source of human rabies deaths in the United States. Improving rabies awareness and preventing human exposure to rabid bats remains a national public health priority today. Concurrently, conservation of bats and the ecosystem benefits they provide is of increasing importance due to declining populations of many bat species. This study used a visitor-intercept experiment (N = 521) in two U.S. national parks where human and bat interactions occur on an occasional basis to examine the relative persuasiveness of four messages differing in the provision of benefit and uncertainty information on intentions …

Spillover Effects In Mutual Fund Companies, Clemens Sialm, T. Mandy Tham May 2016

Spillover Effects In Mutual Fund Companies, Clemens Sialm, T. Mandy Tham

Research Collection Lee Kong Chian School Of Business

Our paper investigates spillover effects across different business segments of publicly traded financial conglomerates. We find that the investment decisions of mutual fund shareholders do not depend only on the prior performance of the mutual funds; they also depend on the prior performance of the funds’ management companies. Flows into equity and bond mutual funds increase with the prior stock price performance of the funds’ management companies after controlling for fund performance and other fund characteristics. The sensitivity of flows to the management company’s performance is not justified by the subsequent performance of the affiliated funds. The results indicate that …

Portfolio Manager Compensation And Mutual Fund Performance, Linlin Ma, Yuehua Tang, Juan-Pedro Gomez May 2016

Portfolio Manager Compensation And Mutual Fund Performance, Linlin Ma, Yuehua Tang, Juan-Pedro Gomez

Research Collection Lee Kong Chian School Of Business

We use a novel dataset to study the relation between individual portfolio manager compensation and mutual fund performance. Managers with explicit performance-based pay exhibit superior subsequent fund performance, especially when investment advisors link pay to performance over a longer time period. In contrast, alternative compensation arrangements, such as fixed salary, assets-based pay, or advisor-profits-based pay are not associated with superior performance. Our tests further show that the positive relation between performance-based contracts and fund performance is not driven by the selection of talented managers proxied by education background. Lastly, managers with performance-based pay engage less in risk-shifting activities.

The Regret Elements Scale: Distinguishing The Emotional And Cognitive Components Of Regret, Joshua Buchanan, Amy Summerville, Jennifer Lehmann, Jochen Reb May 2016

The Regret Elements Scale: Distinguishing The Emotional And Cognitive Components Of Regret, Joshua Buchanan, Amy Summerville, Jennifer Lehmann, Jochen Reb

Research Collection Lee Kong Chian School Of Business

Regret is one of the most common emotions, but researchers generally measure it in an ad-hoc, unvalidated fashion. Three studies outline the construction and validation of the Regret Elements Scale (RES), which distinguishes between an affective component of regret, associated with maladaptive affective outcomes, and a cognitive component of regret, associated with functional preparatory outcomes. The present research demonstrates the RES’s relationship with distress (Study 1), appraisals of emotions (Study 2), and existing measures of regret (Study 3). We further demonstrate the RES’s ability to differentiate regret from other negative emotions (Study 2) and related traits (Study 3). The scale …

Bridge Or Buffer: Two Ideas Of Effective Corporate Governance And Public Engagement, Soojin Kim, Jeong-Nam Kim May 2016

Bridge Or Buffer: Two Ideas Of Effective Corporate Governance And Public Engagement, Soojin Kim, Jeong-Nam Kim

Research Collection Lee Kong Chian School Of Business

This study identifies organizational factors that influence corporate governance and formulation of public relations strategies for public engagement. This study explores intertwined relationships between public relations strategies and organizational factors. A total of 22 qualitative interviews were conducted with a diverse pool of communication consultants. Results show that the two public relations strategies, bridging and buffering, are frequently observed and linked with key factors such as size, organizational culture, environment specificity, and strategic orientation. Implications for future public relations and corporate governance research are discussed.

Sidestepping The Rock And The Hard Place: The Private Avoidance Of Prosocial Requests, Stephanie C. Lin, Rebecca L. Schaumberg, Taly Reich May 2016

Sidestepping The Rock And The Hard Place: The Private Avoidance Of Prosocial Requests, Stephanie C. Lin, Rebecca L. Schaumberg, Taly Reich

Research Collection Lee Kong Chian School Of Business

For some, facing a prosocial request feels like being trapped between a rock and a hard place, requiring either a resource (e.g., money) or psychological (e.g., self-reproach) cost. Because both outcomes are dissatisfying, we propose that these people are motivated to avoid prosocial requests, even when they face these requests in private, anonymous contexts. In two experiments, in which participants' anonymity and privacy was assured, participants avoided facing prosocial requests and were willing to do so at a personal cost. This was true both for people who would have otherwise complied with the request and those who would have otherwise …

Knowledge Cluster Development Through Connectivity: Examples From Southeast Asia, Hans-Dieter Evers, Thomas Menkhoff Apr 2016

Knowledge Cluster Development Through Connectivity: Examples From Southeast Asia, Hans-Dieter Evers, Thomas Menkhoff

Research Collection School Of Computing and Information Systems

Whereas since the 1990s national and regional planners saw the creation of knowledge clusters as a panacea for gaining a competitive advantage to propel a region or country into a higher stage of industrial development, recent research suggests that connectivity (e.g. through broadband penetration or joint research connections with collaborators elsewhere) is one of the enablers for socio-economic development. This paper will draw on the results of studies on knowledge clusters in Southeast Asian countries (Malaysia, Brunei, Singapore) as well as the relevant current literature to ask the question, whether knowledge clusters really contribute to regional development and if yes, …

Olps: A Toolbox For On-Line Portfolio Selection, Bin Li, Doyen Sahoo, Hoi, Steven C. H. Apr 2016

Olps: A Toolbox For On-Line Portfolio Selection, Bin Li, Doyen Sahoo, Hoi, Steven C. H.

Research Collection School Of Computing and Information Systems

On-line portfolio selection is a practical financial engineering problem, which aims to sequentially allocate capital among a set of assets in order to maximize long-term return. In recent years, a variety of machine learning algorithms have been proposed to address this challenging problem, but no comprehensive open-source toolbox has been released for various reasons. This article presents the first open-source toolbox for "On-Line Portfolio Selection" (OLPS), which implements a collection of classical and state-of-the-art strategies powered by machine learning algorithms. We hope that OLPS can facilitate the development of new learning methods and enable the performance benchmarking and comparisons of …

Patrol Scheduling In An Urban Rail Network, Hoong Chuin Lau, Zhi Yuan, Aldy Gunawan Apr 2016

Patrol Scheduling In An Urban Rail Network, Hoong Chuin Lau, Zhi Yuan, Aldy Gunawan

Research Collection School Of Computing and Information Systems

This paper presents the problem of scheduling security teams to patrol a mass rapid transit rail network of a large urban city. The main objective of patrol scheduling is to deploy security teams to stations of the network at varying time periods subject to rostering as well as security-related constraints. We present several mathematical programming models for different variants of this problem. To generate randomized schedules on a regular basis, we propose injecting randomness by varying the start time and break time for each team as well as varying the visit frequency and visit time for each station according to …
