What Do Business School Deans Do? Insights From A Uk Study, Julie Davies, Howard Thomas

Research Collection Lee Kong Chian School Of Business

During the last 40 years, the growth and impact of UK business schools have been significant. Relatively few studies have reviewed how business school deans emerge and grow. This paper aims to explore the experiences and psychometric profiles of UK business school leaders to understand their tenures, problems, dilemmas and succession issues. The study comprised 16 semi-structured interviews with business school deans and Myers-Briggs Type Indicator (MBTI) questionnaires completed by deans and aspiring deans (associate deans and heads of department). The study uses the executive life cycle and concepts of social capital as theoretical frameworks to understand the dean's role. …

Asking Tougher Questions In Tough Times, Irving Low, Claudia Eio, See Liang Foo, Yang Hoong Pang, Kwong Sin Leong, John Joseph Williams

Research Collection School Of Accountancy

The recent wave of corporate governance disasters globally raises many eyebrows and burning questions whether audit committees (ACs) are doing the right things to effectively discharge their roles and responsibilities. To further test the integrity and reputation of the Singapore market as a listing gateway for foreign companies in turbulent times like these, the headlines are also reporting a spate of suspected and actual corporate fraud and scandals involving China-based, Singapore listed companies (commonly referred to as “S-chips”). Many angry investors and the public question whether ACs and independent directors are doing their jobs.

Corporate Tax, Capital Structure, And The Accessibility Of Bank Loans: Evidence From China, Liansheng Wu, Heng Yue

Research Collection School Of Accountancy

In this paper, we investigate whether listed firms in China adjust their capital structure in response to an increase in the corporate taxrate. Although theories of capital structure suggest that corporate tax is an important determinant of capital structure, how exogenouschanges of the tax rate affect firms’ leverage decisions has not been fully explored. We examine a unique circumstance in which the Chinesegovernment increased the corporate tax rate of firms that had previously received local government tax rebates. The evidence indicatesthat these firms increased their leverage when the corporate tax rate increased. Further investigation suggests that the adjustment ofleverage was …

"I Know What You Want To Know": The Impact Of Interviewees' Ability To Identify Criteria On Interview Performance And Construct-Related Validity, Klaus G. Melchers, Ute Christine Klehe, Gerald M. Richter, Martin Kleinmann, Cornelius J. Konig, Filip Lievens

Research Collection Lee Kong Chian School Of Business

The current study tested whether candidates' ability to identify the targeted interview dimensions fosters their interview success as well as the interviews' convergent and discriminant validity. Ninety-two interviewees participated in a simulated structured interview developed to measure three different dimensions. In line with the hypotheses, interviewees who were more proficient at identifying the targeted dimensions received better evaluations. Furthermore, interviewees' ability to identify these evaluation criteria accounted for substantial variance in predicting their performance even after controlling for cognitive ability. Finally, the interviewer ratings showed poor discriminant and convergent validity. However, we found some support for the hypothesis that the …

Does Size Matter In The Hedge Fund Industry?, Song Wee Melvyn Teo

Research Collection Lee Kong Chian School Of Business

We document a negative and convex relationship between hedge fund size and future risk-adjusted returns. Small hedge funds outperform large hedge funds by 3.65 percent per year after adjusting for risk. This over performance is not driven by fund age, leverage, serial correlation, or self-selection biases. The capacity constraints manifest across various investment styles and regions. In particular, they are strongest for funds managed by multiple principals who trade small, illiquid securities, suggesting that the observed diseconomies can be traced to price impact and hierarchy costs (Stein, 2002). While investors direct disproportionately more capital to smaller funds, they do not …

Assessment Centres: A Tale About Dimensions, Exercises, And Dancing Bears, Filip Lievens

Research Collection Lee Kong Chian School Of Business

This study reviews prior construct-related validity research in assessment centres. Special focus is placed on disentangling possible explanations for the construct-related validity findings. The conclusion is that we now have a much better picture of the reasons behind the construct-related validity findings. Careful assessment centre design and high interrater reliability among assessors seem necessary albeit insufficient conditions to establish assessment centre construct-related validity. The nature of candidate performances is another key factor. This study next discusses how these empirical findings have changed how assessment centres are conceptualized (theoretical advancements framed in the application of trait activation theory), analysed (methodological advancements), …

Evidence For The Validity Of The Children’S Attraction To Physical Activity Questionnaire (Capa) With Young Children, Elizabeth Rose, Dawne Larkin, Beth P. Hands, Barbara Howard, Helen Parker

Health Sciences Papers and Journal Articles

Attraction to physical activity is important to an individual’s intrinsic motivation to engage in play, games and sports. While there are instruments designed to measure attraction to physical activity in middle childhood years, the lack of authentic measures in young children has impeded research in this area.

In this study we sought to address the validity of a scale to tap young children’s attraction to physical activity. Evidence for validity was based on internal consistency, content analysis, and factor structure.

Australian school children (180 boys and 154 girls) from school year two, aged six to eight years, were individually administered …

Latin American, Latino and Iberian Studies Faculty Publications

L'activitat teatral entre 1959 i 1991 està marcada pels intents de creació d'un teatre nacional a partir dels grups independents i, després del 1975, amb el suport institucional. Moltes de les iniciatives del teatre independent, allunyades del teatre espanyol comercial, professional i/o «oficial» del moment, tingueren l'origen en l'Agrupació Dramàtica de Barcelona (establerta el 1955 per Ferran Soldevila, amb un divers grup d'artistes), el Teatre Viu (creat el 1956 per Ricard Salvat, Miquel Porter i Elena Estellés) i l'Escola d'Art Dramàtic Adrià Gual, que havien fundat Salvat i Maria Aurèlia Capmany el 1960. En aquests nuclis es formaren Josep Anton …

Inside All-Optical Networks, Sana Tariq

Theses

Imagine a world where lightning speed Internet is as common as telephones today. Imagine when light, the fastest moving thing in the universe, is the signal-carrying transport medium. Imagine when bandwidth no more remains a constraint for any application. Imagine when imagination is the only limit! This all can be made possible with only one technology and that is optical communication. Optical networks have thus far provided a realization to a greater extent to the unlimited bandwidth dreams of this era, but as the demands are increasing, the electro-optic conversions seem to become bottlenecks in blended optical networks. The only …

Content-Based Addressing In Hierarchical Distributed Hash Tables, Joseph Srebro

Theses

Peer-to-peer networks have drawn their strength from their ability to operate functionally without the use of a central agent. In recent years the development of the structured peer-to-peer network has further increased the distributed nature of p2p systems. These networks take advantage of an underlying distributed data structure, a common one is the distributed hash table (DHT). These peers use this structure to act as equals in a network, sharing the same responsibilities of maintaining and contributing. But herein lays the problem, not all peers are equal in terms of resources and power. And with no central agent to monitor …

Towards Virtual Machine Integrity Using Introspection, Sammy Lin

Theses

The Integrity Measurements Architecture (IMA) provides attestation and integrity for Linux hosts. But what if an administrator wants to provide IMA functionality to an older (non-IMA capable) or a non Linux-based OS? If the system is deployed on top of a hypervisor, IMA functionality can be provided at the hypervisor level. This paper applies Virtual Machine Introspection (VMI) to provide IMA functionality to virtualized guest OSes. We implement a proof of concept library (using a shallow shadow filesystem) and integrate it with the Kernel-based Virtual Machine (KVM) hypervisor. The modifications provide the Linux host OS the ability to see when …

Data Center Design & Enterprise Networking, Christian Mahood

Theses

Today’s enterprise networks and data centers have become very complex and have completely integrated themselves into every facet of their represented organization. Organizations require Internet facing services and applications to be available at any part of the day or night. These organizations have realized that with centralized computing and highly available components, their technological presence with customers can be greatly enhanced. The creation of an infrastructure supporting such high availability takes numerous components and resources to function optimally. When an organization makes the decision to design a data center, they utilize resources to provide insight into what components to deploy. …

Reactive Exploration With Self-Reconfigurable Systems, Eric Fabricant

Theses

Modular self-reconfigurable robots (MSR) are robots composed of modules that translate over one another to permit reconfiguration and locomotion. This construction allows them to traverse a broader range of environments than legged or wheeled robots. MSR also posses the ability to split apart to parallelize their efforts or combine with each other to produce a larger robot capable of navigating more diverse terrain. In this paper we discuss a state-based reactive architecture for the distributed control of cooperative MSR teams in unknown environments. The MSR use local sensory data from the environment and a model of the team to select …

Alternative Sources Of Energy, David Kennedy

Conference Papers

Ireland relies on imports of fossil fuels for up to 83% of its energy needs and this statistic is relatively common in other European countries. Apart from the high import costs and pollutions associated with fossil fuels and the need to meet new targets in terms of CO2 emissions, energy security is essential. This paper provides an overview and outline of the different alternative energy sources available for use either at domestic or on large scale production, some of which are established and others less likely to succeed in our climate.
Some of the alternative energy sources such as wind …

Public Private Partnerships: A Licence To Print Money Or Value For Money?, Raymond Turner

Level 3

It is often considered that a Public Private Partnership (PPP) is a licence to print money for the private entity and that the state receives a price which does reflect the value of the underlying public asset.

This paper explores key concepts that underpin and define the nature of PPPs and how such partnerships have emerged and evolved as a means of project funding. The relationship between the underlying asset and the ownership of the derived benefit from the consumption of the public asset is explored to illustrate how the same asset can represent different values.
