Responsibility Of Schools In Dispensing Equal Justice: A Singapore Case Study, Rathna Nathan Jan 2011

Responsibility Of Schools In Dispensing Equal Justice: A Singapore Case Study, Rathna Nathan

Research Collection Yong Pung How School Of Law

The gap between the needs of indigents and the state subsidised legal services or pro bono legal services exist in all societies. Traditionally, the state and the legal fraternity have assumed responsibility to bridge this gap. Law schools have traditionally and culturally confined themselves to the academic instruction of the law. This paper considers whether law schools have an equal responsibility to plug this gap. Four main issues are considered. First, law schools have a professional responsibility to instill legal professionalism in law students, which includes educating students in a pro bono culture. Second, these responsibilities can be effectively discharged …

Do Individual Differences In Perceiving Situational Demands Moderate The Relationship Between Personality And Assessment Center Dimension Ratings?, Anne Jansen, Filip Lievens, Martin Kleinmann Jan 2011

Do Individual Differences In Perceiving Situational Demands Moderate The Relationship Between Personality And Assessment Center Dimension Ratings?, Anne Jansen, Filip Lievens, Martin Kleinmann

Research Collection Lee Kong Chian School Of Business

This study contributes to research on assessment centers' (AC) external construct-related validity by investigating a potential moderator of the relationship between personality and AC dimension ratings. On the basis of recent insights in person-situation contingencies we hypothesized that individual differences in people's perception of situational demands moderate the relationship between personality and conceptually related AC dimension ratings. The hypotheses were tested with 108 individuals in two leaderless group discussion exercises. Results confirmed the hypotheses for two of the three traits (i.e., Agreeableness and Conscientiousness). In particular, people high on these traits who identified the situational demands received higher AC dimension …

Sham Marriages, Ancillary Powers, And Moral Discourse: Toh Seok Kheng V. Huang Huiqun; Adp V. Adq, Siyuan Chen Jan 2011

Sham Marriages, Ancillary Powers, And Moral Discourse: Toh Seok Kheng V. Huang Huiqun; Adp V. Adq, Siyuan Chen

Research Collection Yong Pung How School Of Law

Is marriage an institution (of public morality) or a contract (of private ordering)? In Toh Seok Kheng, the High Court concluded that it was unable to declare a “sham marriage” void just because the motives behind the marriage seemed improper. In ADP, the High Court held that since a void marriage meant there was no marriage to begin with, the “wife” was not entitled to maintenance, and there could not have been any “matrimonial assets” to be divided, unless she had a strong “moral” claim. This piece considers how the aforementioned moral-contractual dichotomy emerges in these cases.

How Predictable Is The Chinese Stock Market?, Fuwei Jiang, Jun Tu, David Rapach, Jack K. Strauss, Guofu Zhou Jan 2011

How Predictable Is The Chinese Stock Market?, Fuwei Jiang, Jun Tu, David Rapach, Jack K. Strauss, Guofu Zhou

Research Collection Lee Kong Chian School Of Business

We analyze return predictability for the Chinese stock market index and its components sorted on industry, size, book-to-market and ownership concentration, with both in-sample and out-of-sample tests. We find significant predictability. Among industry portfolios, Finance and insurance, Real estate, and Manufacturing exhibit the most predictability, while small-cap, low book-to-market ratio and low ownership concentration firms also display considerable predictability. The conditional CAPM model largely accounts for component predictability, and industry concentration significantly explain differences in return predictability across industries, consistent with the information-flow frictions emphasized by Hong, Torous, and Valkanov (2007).

A Quantitative Analysis And Natural History Of B. F. Skinner’S Coauthoring Practices, Todd L. Mckerchar, Edward K. Morris, Nathaniel G. Smith Jan 2011

A Quantitative Analysis And Natural History Of B. F. Skinner’S Coauthoring Practices, Todd L. Mckerchar, Edward K. Morris, Nathaniel G. Smith

Research, Publications & Creative Work

This paper describes and analyzes B. F. Skinner’s coauthoring practices. After identifying his 35 coauthored publications and 27 coauthors, we analyze his coauthored works by their form (e.g., journal articles) and kind (e.g., empirical); identify the journals in which he published and their type (e.g., data-type); describe his overall and local rates of publishing with his coauthors (e.g., noting breaks in the latter); and compare his coauthoring practices with his single-authoring practices (e.g., form, kind, journal type) and with those in the scientometric literature (e.g., majority of coauthored publications are empirical). We address these findings in the context of describing …

Evaluation Of The Iqa Delay Estimation Method, Yaye Keita, Mitsuru Saito Jan 2011

Evaluation Of The Iqa Delay Estimation Method, Yaye Keita, Mitsuru Saito

CUTR Faculty Journal Publications

The Incremental Queue Accumulation (IQA) method is the new delay estimation method for signalized intersections adopted for the Highway Capacity Manual 2010. Using a signalized intersection and a remote data collection facility, the IQA method was evaluated for its accuracy and for potential challenges that practitioners may encounter as they use the new method. The results were compared with delays obtained by the delay estimation models included in the Highway Capacity Manual 2000. It was found that the IQA method was promising and theoretically more robust than the current delay estimation model, but field data collection could be challenging. © …

Strategic Behavior In Schelling Dynamics: A New Result And Experimental Evidence, Juan Miguel Benito, Pablo Brañas-Garza, Penélope Hern´Andez, Juan A. Sanchis Jan 2011

Strategic Behavior In Schelling Dynamics: A New Result And Experimental Evidence, Juan Miguel Benito, Pablo Brañas-Garza, Penélope Hern´Andez, Juan A. Sanchis

ESI Working Papers

In this paper we experimentally test Schelling’s (1971) segregation model and confirm the striking result of segregation. In addition, we extend Schelling’s model theoretically by adding strategic behavior and moving costs. We obtain a unique subgame perfect equilibrium in which rational agents facing moving costs may find it optimal not to move (anticipating other participants’ movements). This equilibrium is far for full segregation. We run experiments for this extended Schelling model. We find that the percentage of strategic players dramatically increases with the cost of moving and that the degree of segregation depends on the distribution of rational subjects.

Double Bubbles In Assets Markets With Multiple Generations, Cary Deck, David Porter, Vernon Smith Jan 2011

Double Bubbles In Assets Markets With Multiple Generations, Cary Deck, David Porter, Vernon Smith

ESI Working Papers

We construct an asset market in a finite horizon overlapping-generations environment. Subjects are tested for comprehension of their fundamental value exchange environment, and then reminded during each of 25 periods of its declining new value. We observe price bubbles forming when new generations enter the market with additional liquidity and bursting as old generations exit the market and withdrawing cash. The entry and exit of traders in the market creates an M shaped double bubble price path over the life of the traded asset. This finding is significant in documenting that bubbles can reoccur within one extended trading horizon and, …

Cognitive Effort In The Beauty Contest Game, Pablo Brañas-Garza, Teresa García-Muñoz Jan 2011

Cognitive Effort In The Beauty Contest Game, Pablo Brañas-Garza, Teresa García-Muñoz

ESI Working Papers

This paper analyzes cognitive effort in 6 different one-shot p-beauty games. We use both Raven and Cognitive Reáection tests to identify subjects' abilities. We find that the Raven test does not provide any insight on beauty contest game playing but CRT does: subjects with higher scores on this test are more prone to play dominant strategies.

Don’T Ask Me If You Will Not Listen: The Dilemma Of Participative Decision Making, Brice Corgnet, Roberto Hérnan-Gonzalez Jan 2011

Don’T Ask Me If You Will Not Listen: The Dilemma Of Participative Decision Making, Brice Corgnet, Roberto Hérnan-Gonzalez

ESI Working Papers

We study the effect of participative decision making in an experimental principalagent game, where the principal can consult the agent’s preferred option regarding the task to be undertaken in the final stage of the game. We show that consulting the agent was beneficial to principals as long as they followed the agent’s choice. Ignoring the agent’s choice was detrimental to the principal as it engendered negative emotions and low levels of transfers. Nevertheless, the majority of principals were reluctant to change their mind and adopt the agent’s proposal. Our results suggest that the ability to change one’s own mind is …

Transparency, Efficiency And The Distribution Of Economic Welfare In Pass-Through Investment Trust Games, Thomas A. Rietz, Roman M. Sheremeta, Timothy W. Shields, Vernon Smith Jan 2011

Transparency, Efficiency And The Distribution Of Economic Welfare In Pass-Through Investment Trust Games, Thomas A. Rietz, Roman M. Sheremeta, Timothy W. Shields, Vernon Smith

ESI Working Papers

We design an experiment to examine welfare and behavior in a multi-level trust game representing a pass through investment in an intermediated market. In a repeated game, an Investor invests via an Intermediary who lends to a Borrower. A pre-experiment one-shot version of the game serves as a baseline and to type each subject. We alter the transparency of exchanges between non-adjacent parties. We find transparency of the exchanges between the investor and intermediary does not significantly affect welfare. However, transparency regarding exchanges between the intermediary and borrower promotes trust on the part of the investor, increasing welfare. Further, this …

You Can Lead Them To Water, But You Can’T Make Them Drink: Using Crowd Sourcing To Lead Library Patrons To Extended Library Services Relevant To Their Search Criteria, William B. Lund, Chad Hansen Jan 2011

You Can Lead Them To Water, But You Can’T Make Them Drink: Using Crowd Sourcing To Lead Library Patrons To Extended Library Services Relevant To Their Search Criteria, William B. Lund, Chad Hansen

Faculty Publications

The Lee Library at Brigham Young University has extensive resources in the forms of highly skilled subject librarians, print resources and digital collections, but getting the students to be aware of and use them effectively is a problem. To help inform library patrons of these resources librarian subject specialists have created over 150 subject guides using LibGuides for subject areas, classes, and some subspecialties, which was an enormous task; but are these resources being used effectively? This paper explores and reports on a subject guide recommender system, which recommends relevant subject guides based on patron searches, using a crowd sourced …

Real-Time Traffic Estimation Using Data Expansion, Roger Lederman, Laura Wynter Jan 2011

Real-Time Traffic Estimation Using Data Expansion, Roger Lederman, Laura Wynter

Research Collection School Of Computing and Information Systems

This paper presents a method for estimating missing real-time traffic volumes on a road network using both historical and real-time traffic data. The method was developed to address urban transportation networks where a non-negligible subset of the network links do not have real-time link volumes, and where that data is needed to populate other real-time traffic analytics. Computation is split between an offline calibration and a real-time estimation phase. The offline phase determines link-to-link splitting probabilities for traffic flow propagation that are subsequently used in real-time estimation. The real-time procedure uses current traffic data and is efficient enough to scale …

Estimation And Forecasting Of Dynamic Conditional Covariance: A Semiparametric Multivariate Model, Xiangdong Long, Liangjun Su, Aman Ullah Jan 2011

Estimation And Forecasting Of Dynamic Conditional Covariance: A Semiparametric Multivariate Model, Xiangdong Long, Liangjun Su, Aman Ullah

Research Collection School Of Economics

We propose a semiparametric conditional covariance (SCC) estimator that combines the first-stage parametric conditional covariance (PCC) estimator with the second-stage nonparametric correction estimator in a multiplicative way. We prove the asymptotic normality of our SCC estimator, propose a nonparametric test for the correct specification of PCC models, and study its asymptotic properties. We evaluate the finite sample performance of our test and SCC estimator and compare the latter with that of PCC estimator, purely nonparametric estimator, and Hafner, Dijk, and Franses’s (2006) estimator in terms of mean squared error and Value-at-Risk losses via simulations and real data analyses.

Model Selection In Validation Sampling Data: An Asymptotic Likelihood-Based Lasso Approach, Chenlei Leng, Denis H. Y. Leung Jan 2011

Model Selection In Validation Sampling Data: An Asymptotic Likelihood-Based Lasso Approach, Chenlei Leng, Denis H. Y. Leung

Research Collection School Of Economics

We propose an asymptotic likelihood-based LASSO approach for model selection in regression analysis when data are subject to validation sampling. The method makes use of an initial estimator of the regression coefficients and their asymptotic covariance matrix to form an asymptotic likelihood. This ``working'' objective function facilitates the formulation of the LASSO and the implementation of a fast algorithm. Our method circumvents the need to use a likelihood set-up that requires full distributional assumptions about the data. We show that the resulting estimator is consistent in model selection and that the method has lower prediction errors than a model that …

Monetary Policy In Singapore And The Global Financial Crisis, Hwee Kwan Chow, Peter Wilson Jan 2011

Monetary Policy In Singapore And The Global Financial Crisis, Hwee Kwan Chow, Peter Wilson

Research Collection School Of Economics

Prior to the crisis the consensus amongst central bankers in advanced economies was that price stability, in the form of low and stable price inflation, was a top priority for monetary policy and could best be achieved by targeting interest rates (usually overnight) or monetary aggregates, such as Narrow Money (M1) and Broad Money (M2). Liquidity in the banking system could be flexibly adjusted on a daily basis through open market operations to increase or decrease the monetary base which would be transmitted to the rest of the economy through financial intermediation. Financial markets would then adjust longer-term interest rates …

Making And Unmaking Of Transnational Environmental Cooperation, Yooil Bae, Dong-Ae Shin, Yong-Wook Lee Jan 2011

Making And Unmaking Of Transnational Environmental Cooperation, Yooil Bae, Dong-Ae Shin, Yong-Wook Lee

Research Collection School of Social Sciences

There has been an ongoing debate about how (or through what mechanisms) global environmental norms have influenced domestic political debates that give rise to green policy choices. In particular, effective international environmental cooperation between transnational and domestic NGOs has been recognized as a key to successful environmental movements. In this regard, the central question guiding research on the politics of environmental norms is, under what condition(s) transnational cooperation among NGOs would be more likely to be sustained so as to achieve its goals. This article proposes that one of the mechanisms missing from the debate is a bottom-up approach through …

Maintaining Faith In Agency Under Immutable Constraints: Cognitive Consequences Of Believing In Negotiable Fate, Evelyn Wing-Mun Au, Chi-Yue Chiu, Avinish Chaturvedi, Leeann Mallorie, Madhu Viswanathan, Zhi Xue, Krishna Savani Jan 2011

Maintaining Faith In Agency Under Immutable Constraints: Cognitive Consequences Of Believing In Negotiable Fate, Evelyn Wing-Mun Au, Chi-Yue Chiu, Avinish Chaturvedi, Leeann Mallorie, Madhu Viswanathan, Zhi Xue, Krishna Savani

Research Collection School of Social Sciences

Negotiable fate refers to the idea that one can negotiate with fate for control, and that people can exercise personal agency within the limits that fate has determined. Research on negotiable fate has found greater prevalence of related beliefs in Southeast Asia, East Asia, and Eastern Europe than in Western Europe and English-speaking countries. The present research extends previous findings by exploring the cognitive consequences of the belief in negotiable fate. It was hypothesized that this belief enables individuals to maintain faith in the potency of their personal actions and to remain optimistic in their goal pursuits despite the immutable …

Not Yet Married: The Implications Of Meanings Of Marriage On Youths In Singapore, Paulin T. Straughan Jan 2011

Not Yet Married: The Implications Of Meanings Of Marriage On Youths In Singapore, Paulin T. Straughan

Research Collection School of Social Sciences

Marriage is a social construct that takes on different meanings as societies develop and mature. To understand why people get married, it is important that we understand what marriage means. This paper will discuss the social transformation of marriage in Asia using Singapore as a case study. To examine two demographic trends- delayed marriage, and the increasing proportion of people who remain single - this discourse also explores the constraints imposed by contradictions between traditional norms and modern expectations. In the midst of these ideological challenges, there are important implications for the practice of marriage among younger Singaporeans. We see …

Book Reviews: Advancing Global Education: Patterns Of Potential Human Progress, Devin K. Joshi

Research Collection School of Social Sciences

Education is one of the most fundamental prerequisites to economic growth and social stability in the world. It is also one of the most inadequately realised goals of development, with the average education of global adults remaining essentially at primary levels. Advancing Global Education is the second in a series of volumes that explores prospects for human development-how development appears to be unfolding globally and locally, how we would like it to evolve, and how better to assure that we move it in desired directions. The first volume addressed the reduction of global poverty. The third will turn to the …

The Unresolved Legality Of Online Gambling In Singapore, Siyuan Chen Jan 2011

The Unresolved Legality Of Online Gambling In Singapore, Siyuan Chen

Research Collection Yong Pung How School Of Law

This article addresses what appears to be a hitherto (legislatively and judicially) unresolved issue in a country where gambling is an established sub-culture – the legality of online gambling. The existing legislation does not provide direct answers, and as a result, the courts have not been given the opportunity to answer the question directly either. The police have previously made a few statements to the press and the media, but what should we make of them? While placing bets with unauthorised bookies (including those who operate their own website or use others’ websites) is clearly outlawed, leaving the offender with …

Mad Enough To See The Other Side: Anger And The Search For Disconfirming Information, Maia J. Young, Larissa Z. Tiedens, Heajung Jung, Ming-Hong Tsai Jan 2011

Mad Enough To See The Other Side: Anger And The Search For Disconfirming Information, Maia J. Young, Larissa Z. Tiedens, Heajung Jung, Ming-Hong Tsai

Research Collection School of Social Sciences

The current research explored the effect of anger on hypothesis confirmation the propensity to seek information that confirms rather than disconfirms one's opinion. We argued that the moving against action tendency associated with anger leads angry individuals to seek out more disconfirming information than sad individuals, attenuating the confirmation bias. We tested this hypothesis in two studies of experimentally primed anger and sadness on the selective exposure to hypothesis confirming and disconfirming information. In Study 1, participants in the angry condition were more likely to choose disconfirming information than those in the sad or neutral condition when given the opportunity …

Mate Preferences In The Us And Singapore: A Cross-Cultural Test Of The Mate Preference Priority Model, Norman P. Li, Katherine A. Valentine, Lily Patel Jan 2011

Mate Preferences In The Us And Singapore: A Cross-Cultural Test Of The Mate Preference Priority Model, Norman P. Li, Katherine A. Valentine, Lily Patel

Research Collection School of Social Sciences

Sex differences have been found in mate preferences across several decades. Especially for long-term partners, men tend to value physical attractiveness and women tend to value social status. However, the sexes both value various other traits even more highly. Such findings thus diminish the importance of the sex differences and challenge the theoretical importance that evolutionary psychologists place on physical attractiveness and social status. Using a budget allocation methodology to examine mate preferences in both the US and Singapore, we found not only the usual sex differences, but also evidence that men prioritize physical attractiveness and women prioritize social status …

The Fundamental Question When Applying The Welfare Principle: "Who Will Be The Better Parent Or Guardian"?, Siyuan Chen Jan 2011

The Fundamental Question When Applying The Welfare Principle: "Who Will Be The Better Parent Or Guardian"?, Siyuan Chen

Research Collection Yong Pung How School Of Law

The welfare principle – that is, when making a custody-related decision, the best interests of the child form the first and paramount consideration – is probably one of the cardinal principles of family law in many common law jurisdictions. While the welfare principle is generally considered a wide concept with no exhaustive definition or list of factors, it is submitted that there is an important question – sometimes neglected or misunderstood – that should actually feature most prominently when applying the welfare principle, particularly when joint or no order custody orders seem impossible. The question is simply that of “who …
