Encouraging Knowledge Sharing In Knowledge-Based Organizations: Individual And Organizational Aspects Of Knowledge Management Leadership, Thomas Menkhoff, Yue Wah Chay, Benjamin Loh, Hans-Dieter Evers

Research Collection Lee Kong Chian School Of Business

This study aims to understand the antecedents of knowledge sharing behavior amongst tenant firms in Science and Technology Parks (STPs) which has been highlighted as a key factor for the development of an epistemic culture of innovation in STPs. Components of a model of knowledge management leadership with a focus on knowledge sharing and innovative value creation in STPs are developed inspired by the work of Nonaka, Nahapiet and Ghoshal, Guns and others. Collection of data on various relevant measures is ongoing, covering technology firms and STPs in Singapore and other Asian countries. Besides outlining model components and hypotheses, tentative …

Change Leadership In Small Enterprises: Evidence From Singapore, Thomas Menkhoff, Yue Wah Chay

Research Collection Lee Kong Chian School Of Business

Leading change processes in an enterprise is a challenge for many entrepreneurs. Numerous elements influence the outcomes of such transformation processes, including the adopted change leadership style, the implementation skills of the entrepreneur, the particular scenario of change in terms of urgency of change and resistance, the scale of change as well as macro variables. This article sheds light on the change leadership approaches of small Chinese entrepreneurs in Singapore. It aims at examining widespread common-sense assumptions that æAsianÆ small entrepreneurs adopt mostly directive-coercive (autocratic) change leadership approaches. We argue that there is indeed a great diversity and heterogeneity amongst …

Expanding The Protection Of Geographical Indications Of Origin Under Trips: Old Debate Or New Opportunity, Irene Calboli

Research Collection Yong Pung How School Of Law

Geographical indications of origin (GIs), their definition, and rationale for protection have historically been the subjects of heated debates in the international community. Fierce defenders of GIs protection, European countries have traditionally advocated that GIs should not be used by unrelated parties because GIs identify the unique qualities, characteristics, and reputation of the products to which they are affixed. To this claim, the United States and other "new world" countries have generally responded by pointing out that many GIs are generic terms on their soil, and, thus, consumers could not be confused as to the origin of the products identified …

Monolithic Integration Of Collimating Fresnel Lens For Beam Quality Enhancement In Tapered High Power Laser Diode, F. K. Lau, Chyng Wen Tee, X. Zhao, K. A. Williams, R. V. Penty, I. H. White, M. Calligaro, M. Lecomte, O. Parillaud, N. Michel, M. Krakowski

Research Collection Lee Kong Chian School Of Business

We demonstrate, for the first time, a monolithic integrated lens for wide aperture gain-guided tapered laser beam quality enhancement by compensating the quadratic phase curvature. The 3mm long tapered laser with an output aperture of 170μm adopted in this design consists of a gain-guided tapered section and an index-guided ridge section and operated at 980nm. The lens design is implemented by focus ion beam etching (FIBE) technique, whereby the laser diode is mounted p-side up in order to facilitate the etching process. The lens is located 600μm away from the junction of the tapered and ridge sections, and is 40μm …

Conceptualization Of Trust, Commitment, And Understanding The Relationships Between Trust, Commitment, And Willingness To Try Internet Banking Services, Siew Tong Fock, Hian Chye Koh

Research Collection Lee Kong Chian School Of Business

This paper examines trust and commitment and their antecedents and consequences within the context of Internet banking, based on data collected from a survey of 500 Singapore undergraduates. After the establishment of a conceptual model that links trust and commitment to the willingness to try Internet banking, the empirical findings show that higher levels of trust and commitment are significantly associated with a greater willingness to try Internet banking. The paper also investigates security, ethics, privacy, openness, the speed of response, quality of information, regulatory control, technology advancement, and reputation as determinants of trust. Of these, security, regulatory control, technology …

Conflicts Of Interest And Stock Recommendations: The Effects Of The Global Settlement And Related Regulations, Rong Wang, Ohad Kadan, Leonardo Madureira, Tzachi Zach

Research Collection Lee Kong Chian School Of Business

Prior research has shown that sell-side analysts in general, and especially those facing conflicts of interest driven by investment bank relationships, issue overly optimistic recommendations. This paper studies the effect of regulations on sell-side analysts’ research. These regulations — Rule NASD 2711, Rule NYSE 472, and the “Global Analyst Research Settlement” — attempted to mitigate the interdependence between the research and the investment bank departments of US brokerage houses. The results suggest that the regulations have partially achieved their goal of curbing the conflicts of interest’s influence over analysts’ stock recommendations. After the adoption of the new regulations, the likelihood …

Dynamic Pricing Through Discounts For Optimizing Multiple Class Demand Fulfillment, Qing Ding, Panos Kouvelis, Joseph M. Milner

Research Collection Lee Kong Chian School Of Business

In a multiple-customer-class model of demand fulfillment for a single item, we consider the use of dynamic price discounts to encourage backlogging of demand for customer classes denied immediate service. Customers are assumed to arrive over several stages in a period, and customer classes are distinguished by their contractual price and sensitivity to discounts. Through dynamic programming we determine the optimal discounts to offer, assuming a linear model for the sensitivity of customers to such inducements. We show that customers are served in class order, and allocation of inventory to demand is determined by considering the current number of customers …

Accounting Restatements: Are They Always Bad News For Investors?, Dan Segal, Jeffrey L. Callen, Joshua Livnat

Research Collection School Of Accountancy

This study investigates a large sample of financial statement restatements over the period 1986-2001, and compares restatements caused by changes in accounting principles to those caused by errors. Typically, investors perceive restatements as negative signals due to three potential reasons: (a) the restatement indicates problems with the accounting system that may be manifestations of broader operational (and managerial) problems, (b) the restatement causes downward revisions in future cash flows expectations, and (c) the restatement indicates managerial attempts to cover up income decline through “cooking the books.” We provide evidence that market reactions to restatements due to errors are generally negative. …

A Tuberculosis Contact Investigation Involving Two Private Nursing Homes In Inner Western Sydney In 2004, Bradley Forssman, Leena Gupta, Kay Mills

Medical Papers and Journal Articles

Australia has one of the lowest incidence rates of tuberculosis (TB) in the world, approximately five per 100,000 per year 1, although in some parts of the country the incidence is considerably higher. In the former Central Sydney Area Health Service the incidence rate in 2003 was 14 per 100,000 per year.2 The incidence is also higher in those aged 65 years and over1, a population that has declining immunocompetence due to a variety of factors.3 Furthermore, the subpopulation of this group (and, indeed, of people of any age) living in residential institutions such as nursing homes and hostels are …

Correlates Of Distances Traveled To Use Recreational Facilities For Physical Activity Behaviors, Gavin R. Mccormack, Billie Giles-Corti, Max K. Bulsara, Terri J. Pikora

Medical Papers and Journal Articles

Background: Information regarding how far people are willing to travel to use destinations for different types of recreational physical activity behaviors is limited. This study examines the demographic characteristics, neighborhood opportunity and specific-physical activity behaviors associated with distances traveled to destinations used for recreational physical activity.

Methods: A secondary analysis was undertaken of data (n = 1006) from a survey of Western Australian adults. Road network distances between respondents' homes and 1) formal recreational facilities; 2) beaches and rivers; and 3) parks and ovals used for physical activity were determined. Associations between distances to destinations and demographic characteristics, neighborhood opportunity …

Constructing Indices Representing Supportiveness Of The Physical Environment For Walking Using The Rasch Measurement Model, Gavin R. Mccormack, Louise C. Mâsse, Max K. Bulsara, Terri J. Pikora, Billie Giles-Corti

Medical Papers and Journal Articles

Background: The objectives of this study were to use the Rasch model to 1) assess the psychometric properties of a physical environmental audit instrument and 2) to develop indices of interrelated environmental attributes that summarize environmental supportiveness for walking.

Methods: A set of items were derived representing two conceptual physical environmental constructs: 1) functional/safety, and; 2) aesthetics. Ad hoc criteria based on point-biserial and Rasch-based fit statistics were used to examine the construct validity and internal reliability of the two constructs.

Results: The Rasch-based fit statistics assisted in identifying 12 items that belonged to the functional/safety construct and 4 items …

Little Understood Knowledge Trap, Hans-Dieter Evers, Solvay Gerke, Thomas Menkhoff

Research Collection Lee Kong Chian School Of Business

As knowledge increases, we realise how much else we do not know. Successful research always results in new questions. Any knowledge economy must be aware of such unknowns if it is to expand further through research and development. Debate on bridging the digital divide does not take this factor into account. Many of the strategies currently preached are misplaced.

Capital Structure Dynamics And Stock Returns, Jie Cai, Zhe Zhang

Research Collection Lee Kong Chian School Of Business

Many finance theories predict that the capital structure affects firm value, which implies that the changes in leverage have an impact on stock returns. Most of the existing literature however has been focusing on the determinants of the capital structure. Using a sample of U.S. public firms during 1975-2002, we document a significantly negative effect of leverage changes on next-quarter stock returns. This effect remains significant after controlling for other firm characteristics such as ROE, book-to-market, firm size, and past returns. We propose and test several hypotheses to explain the observed effect. We find that the negative effect is stronger …

The Role Of European Governments In The Digital Economy, Arnoud Cyriel Leo De Meyer

Research Collection Lee Kong Chian School Of Business

What is the role of government in the digital economy? It is not our intention to go into an in-depth ideological debate on whether governments should intervene in the business sector. We will try to adopt a pragmatic approach and explore what already happens in practice. It is up to the reader to make a judgment to what extent the governments should be involved in the ICT sector. There is enough indication that, due to network externality effects, governments need to take on an active role in stimulating an e-environment to jump-start the move toward a higher level of e-readiness.In …

Research Capacity Building In General Practice: A New Opportunity In Fremantle, Wa, Tom Brett, Rachel Sherrard, Adrian Bower

Medical Papers and Journal Articles

One of the great disappointments of primary care medicine has been the failure to develop a strong research tradition among general practitioners. This has happened despite the great legacy left by William Budd, James MacKenzie, and Will Pickles, and the clear acceptance that such research is necessary to improve patient care.

The Earliest Dipodomyine Heteromyid In North America And The Phylogenetic Relationships Of Geomorph Rodent, Steven J Norris

Faculty, Staff and Student Publications

The proteome of the spirochete bacterium Borrelia burgdorferi, the tick-borne agent of Lyme disease, has been characterized by two different approaches using mass spectrometry, providing a launching point for future studies on the dramatic changes in protein expression that occur during transmission of the bacterium between ticks and mammals.

Exploiting Semantic Locality To Improve Peer-To-Peer Search Mechanisms, Ajitabh Sharan

Theses

A Peer-to-Peer(P2P) network is the most popular technology in file sharing today. With the advent of various commercial and non-commercial applications like KaZaA, Gnutella, a P2P network has exercised its growth and popularity to the maximum. Every node (peer) in a P2P network acts as both a client and a server for other peers. A search in P2P network is performed as a query relayed between peers until the peer that contains the searched data is found. Huge data size, complex management requirements, dynamic network conditions and distributed systems are some of the difficult challenges a P2P system faces while …

Relationship Of Human Figure Drawing With Executive Functioning And Achievement, Julie M. Miller

Theses

The purpose of the study was to investigate the relationship between aspects of children’s human figure drawings to their executive functioning and academic achievement. Participants consisted of 80 third and fourth graders, ages 8 to 10 years, along with their parents. Correlational analysis showed no relationship between the developmental scoring of the Goodenough-Harris or Koppitz with measures of executive functioning, as measured by the Behavior Rating Inventory of Executive Functioning (BRIEF; Gioia, Isquith, Guy, & Kenworthy, 2000) and the Cognitive Assessment System (CAS; Naglieri & Das, 1997). However, Koppitz’s emotional indicators were significantly correlated with all aspects of BRIEF and …

A Messaging System To Handle Semantic Dissonance, Ashish Rathod

Theses

Enterprises have been compelled to share their data internally and externally, but creating a consistent view of enterprise data has been challenging. Within a typical enterprise, each division uses its own domain specific data model and schema, and different enterprises obviously use their own data models and schema. Integrating these diverse data models and schemas, which have both syntactic and semantic differences, tends to be complex, slow, and inaccurate. Syntactic differences, i.e., differences in names or layout, have received substantial attention in research. Semantic dissonance simply means that the structure may be similar (or even the same) but the meaning …

Refinements In Using Historical Process Data To Optimize Tolerance Allocation, Kevin Delaney, Pat Phelan

Conference Papers

Tolerance allocation for new products calls for experience and judgment. Whenever products are manufactured using production processes that are similar to existing products it is likely that the trend in production tolerances for both the new and existing products will be similar. It must be assumed that there have been no improvements to the tooling, modifications to the machines being used, or a change in process stability. The data employed to understand and exploit these trends is commonly referred to as process capability data and it is stored in a Process Capability DataBase (PCDB). There are several challenges to be …

The Tromped, An In-Flight Exercise Device To Prevent Flight Related Deep Vein Thrombosis, Carolyn Collins, David Kennedy, Thomas Corrigan, Stephen Jerrams

Conference Papers

Medical and Engineering research studies have shown the potential risks of long haul flight travel and methods of preventing it occurring. The risk of serious health problems or even death is known to arise from lack of venous movement and increased coagulation (clotting) of the blood. These factors contribute to the development of deep vein thrombosis (DVT) and this is more likely to occur in situations where people are seated for long periods during travel on land or in air. Currently long haul airlines have yet to be seen to introduce physical preventative measures against this syndrome.

The Role And Future Of Nanotechnology In Research, Industry And Education, David Kennedy

Conference Papers

Major developments in Nanotechnology have taken place across the world
over the last few years. From a humble beginning, Ireland inc. became a leader in the Microelectronics industry and now has to face the challenge of developing a strategic plan to maintain its lead position in the nano field which in most cases will supersede the micro phase. Most countries are taking a similar path of development all be it alone or in collaboration with other countries. This process is expensive and requires market drivers and experts to lead and deliver demands from the industries of the future. The approach …

Autonomy And Relatedness In Inner-City Families Of Substance Abusing Adolescents, Jessica Samuolis, Aaron Hogue, Sarah Dauber, Howard A. Liddle

Psychology Faculty Publications

This study examined parent-adolescent autonomous-relatedness functioning in inner-city, ethnic minority families of adolescents exhibiting drug abuse and related problem behaviors. Seventy-four parent-adolescent dyads completed a structured interaction task prior to the start of treatment that was coded using an established autonomous-relatedness measure. Adolescent drug use, externalizing, and internalizing behaviors were assessed. Parents and adolescents completed assessment instruments measuring parenting style and family conflict. Confirmatory factor analysis found significant differences in the underlying dimensions of parent and adolescent autonomous-relatedness in this sample versus previous samples. It was also found that autonomous-relatedness was associated with worse adolescent symptomatology and family impairment. Results …

Moving A Part-Time Engineering Course To A Student-Centred Paradigm, Kevin Kelly

Level 3

This paper is a further reflection on two conference papers presented at the World Conference for Continuing Engineering Education (WCCEE) in Vienna in April 2006 and National University of Ireland (NUI) Galway Conference: The Challenge of Diversity: Teaching, Support and Student Learning , June 2006. Both conference papers dealt with different aspects of my experiences of the theoretical and pedagogical changes required in re-design and delivery of a part-time engineering programme for the continuing education development of electrical engineers in the workforce.

The Teaching-Research Relationship In Higher Education, Claire M. Mcdonnell

Level 3

This paper examines higher education policy regarding the relationship between research and teaching. The initial issue dealt with is whether current policy in Irish higher education recognises a relationship between research and teaching, and to examine the dual role of academics as teachers and as researchers. This is followed by an examination of any measures put in place to manage and balance the teaching–research relationship. The way in which the relationship between research and teaching is dealt with both in my own institution, the Dublin Institute of Technology, and in higher education policy in a number of other countries is …

Enhanced Nutty Flavor Formation In Cheddar Cheese Made With Malty Lactococcus Lactis Adjunct Culture, M. E. Carunchia Whetstine, M. A. Drake, Jeff Broadbent, Donald J. Mcmahon

Nutrition, Dietetics, and Food Sciences Faculty Publications

Nutty flavor in Cheddar cheese is desirable, and recent research demonstrated that 2- and 3-methyl butanal and 2-methyl propanal were primary sources of nutty flavors in Cheddar. Because malty strains of Lac-tococcus lactis (formerly Streptococcus lactis var. malti-genes) are characterized by the efficient production of these and other Strecker aldehydes during growth, this study investigated the influence of a malty L. lactis adjunct culture on nutty flavor development in Cheddar cheese. Cheeses made with different adjunct levels (0, 10(4) cfu/mL, and 10(5) cfu/mL) were ripened at 5 or 13 degrees C and analyzed after 1 wk, 4 mo, and 8 …

The Fit Between Task And Medium In Sending Equivocal And Unequivocal Messages: How Self-Reported Skill Creates Self-Reported Attitude In Using The Medium, Teresa Merritt

Theses

Communication channels selected by members of an organization can have an impact on the outcome of the messages sent. The media richness theory proposes that task performance can be optimized when task information is matched with the medium's ability to convey information richness. The current study surveyed 25 support staff within the College of Imaging Arts and Sciences at Rochester Institute of Technology to evaluate the best media fit between task and medium for sending equivocal (ambiguous) and unequivocal (clear and concise) messages. The findings supported the media richness theory, and employees report positive attitudes associated with media use.
