An Empirical Test Of The Structure, Conduct-Performance Paradigm In The Asian And Pacific Basin Countries, Abdur Chowdhury Jul 2014

An Empirical Test Of The Structure, Conduct-Performance Paradigm In The Asian And Pacific Basin Countries, Abdur Chowdhury

Abdur R. Chowdhury

This paper tests the structure‐conduct‐performance paradigm in eighteen Asian and Pacific Basin countries. The results suggest that concentration in the banking markets in these countries lead to monopoly profits being earned and is a signal of collusive behaviour among the leading banks. Competitive imperfections allow banks to set prices that are less favourable to consumers thereby decreasing total consumer and producer surplus. This has important policy implications for merger activity. A further increase in concentration in the banking market in these countries will decrease the level of competition in the market. Regulatory actions, such as anti‐trust laws, are justified on …


The Effect Of Ownership Structure On Leverage Decision: New Evidence From Chinese Listed Firms, Qigui Liu, Gary Tian, Xiaoming Wang Jan 2014

The Effect Of Ownership Structure On Leverage Decision: New Evidence From Chinese Listed Firms, Qigui Liu, Gary Tian, Xiaoming Wang

Qigui Liu

This paper examines the effect of state control and ownership structure on the leverage decision of firms listed in the Chinese stock market. Our results show that state-owned enterprises (SOEs) have higher leverage ratios than non-SOEs, and SOEs in regions with a poorer institutional environment have higher leverage ratios than SOEs in better regions. We also show that the largest shareholding (the percentage of shares held by the largest shareholder) in the SOEs has a negative relationship with the leverage ratio, while the largest shareholding in non-SOEs has a non-linear relationship with the short-term and long-term debt ratios. Finally, this …


Solution Structure Of Domains Iva And V Of The Tau Subunit Of Escherichia Coli Dna Polymerase Iii And Interaction With The Alpha Subunit, Xun-Cheng Su, Slobodan Jergic, Max A Keniry, Nicholas E. Dixon, Gottfried Otting Jul 2013

Solution Structure Of Domains Iva And V Of The Tau Subunit Of Escherichia Coli Dna Polymerase Iii And Interaction With The Alpha Subunit, Xun-Cheng Su, Slobodan Jergic, Max A Keniry, Nicholas E. Dixon, Gottfried Otting

Professor Nick E Dixon

The solution structure of the C-terminal Domain V of the τ subunit of E. coli DNA polymerase III was determined by nuclear magnetic resonance (NMR) spectroscopy. The fold is unique to τ subunits. Amino acid sequence conservation is pronounced for hydrophobic residues that form the structural core of the protein, indicating that the fold is representative for τ subunits from a wide range of different bacteria. The interaction between the polymerase subunits τ and α was studied by NMR experiments where α was incubated with full-length C-terminal domain (τC16), and domains shortened at the C-terminus by 11 and 18 residues, …


Structure Of The Theta Subunit Of Escherichia Coli Dna Polymerase Iii In Complex With The Epsilon Subunit, Max A Keniry, Ah-Young Park, Elisabeth A. Owen, Samir M. Hamdan, Guido Pintacuda, Gottfried Otting, Nicholas E. Dixon Jul 2013

Structure Of The Theta Subunit Of Escherichia Coli Dna Polymerase Iii In Complex With The Epsilon Subunit, Max A Keniry, Ah-Young Park, Elisabeth A. Owen, Samir M. Hamdan, Guido Pintacuda, Gottfried Otting, Nicholas E. Dixon

Professor Nick E Dixon

The catalytic core of Escherichia coli DNA polymerase III contains three tightly associated subunits, the α, ε, and θ subunits. The θ subunit is the smallest and least understood subunit. The three-dimensional structure of θ in a complex with the unlabeled N-terminal domain of the ε subunit, ε186, was determined by multidimensional nuclear magnetic resonance spectroscopy. The structure was refined using pseudocontact shifts that resulted from inserting a lanthanide ion (Dy3+, Er3+, or Ho3+) at the active site of ε186. The structure determination revealed a three-helix bundle fold that is similar to the solution structures of θ in a methanol-water …


Replication Termination In Escherichia Coli: Structure And Anti-Helicase Activity Of The Tus-Ter Complex, Cameron Neylon, Andrew V. Kralicek, Thomas M. Hill, Nicholas E. Dixon Jul 2013

Replication Termination In Escherichia Coli: Structure And Anti-Helicase Activity Of The Tus-Ter Complex, Cameron Neylon, Andrew V. Kralicek, Thomas M. Hill, Nicholas E. Dixon

Professor Nick E Dixon

The arrest of DNA replication in Escherichia coli is triggered by the encounter of a replisome with a Tus protein-Ter DNA complex. A replication fork can pass through a Tus-Ter complex when traveling in one direction but not the other, and the chromosomal Ter sites are oriented so replication forks can enter, but not exit, the terminus region. The Tus-Ter complex acts by blocking the action of the replicative DnaB helicase, but details of the mechanism are uncertain. One proposed mechanism involves a specific interaction between Tus-Ter and the helicase that prevents further DNA unwinding, while another is that the …


Flexibility Revealed By The 1.85 Å Crystal Structure Of The Β Sliding-Clamp Subunit Of Escherichia Coli Dna Polymerase Iii, Aaron J. Oakley, Pavel Prosselkov, Gene Wijffels, Jennifer L. Beck, Matthew Cj Wilce, Nicholas E. Dixon Jul 2013

Flexibility Revealed By The 1.85 Å Crystal Structure Of The Β Sliding-Clamp Subunit Of Escherichia Coli Dna Polymerase Iii, Aaron J. Oakley, Pavel Prosselkov, Gene Wijffels, Jennifer L. Beck, Matthew Cj Wilce, Nicholas E. Dixon

Professor Nick E Dixon

The subunit of the Escherichia coli replicative DNA polymerase III holoenzyme is the sliding clamp that interacts with the (polymerase) subunit to maintain the high processivity of the enzyme. The protein is a ring-shaped dimer of 40.6 kDa subunits whose structure has previously been determined at a resolution of 2.5 Å [Kong et al. (1992), Cell, 69, 425-437]. Here, the construction of a new plasmid that directs overproduction of to very high levels and a simple procedure for large-scale purification of the protein are described. Crystals grown under slightly modified conditions diffracted to beyond 1.9 Å at 100 K at …


Disproportional Ownership Structure And Pay-Performance Relationship: Evidence From China's Listed Firms, Jerry Cao, Xiaofei Pan, Gary G. Tian May 2013

Disproportional Ownership Structure And Pay-Performance Relationship: Evidence From China's Listed Firms, Jerry Cao, Xiaofei Pan, Gary G. Tian

Xiaofei Pan

This paper examines the impact of disproportional ownership structure on the pay-performance relationship in China’s listed firms. We find that the cash flow rights of the ultimate controlling shareholder have a positive effect on this relationship while a divergence between the control rights and cash flow rights has a significantly negative effect. By dividing our sample into state owned enterprises (SOE), state assets management bureaus (SAMB), and privately controlled firms, we find that cash flow rights in SOE controlled firms have a significant impact on accounting based pay performance and cash flow rights in privately controlled firms also affect the …

Capital Structure And Firm Performance In Emerging Economies: An Empirical Analysis Of Sri Lankan Firms, Anura De Zoysa, Muhammad Chowdhury, Palli Mulla K A Chandrakumara, Athula Manawaduge

Anil Chandrakumara

This paper offers an empirical analysis of the impact of capital structure on firm performance in thecontext of an emerging market¿Sri Lanka. The study applies both pooled and panel data regressionmodels for a sample of 155 Sri Lankan-listed firms. The results demonstrate that most of the SriLankan firms finance their operations with short-term debt capital as against the long-term debtcapital and provide strong evidence that the firm performance is negatively affected by the use of debtcapital. The study also finds a significant negative relationship between tangibility and performanceindicating inefficient utilization of non-current assets. The negative performance implicationsassociated with over-utilization of …

Anil Chandrakumara

Using panel data regression analysis for a sample of 171 companies, this paper examines the implications of capital structure of corporate entities in an emerging market, Sri Lanka. The results demonstrate that most of the Sri Lankan firms finance their operations with short-term debt capital as against the long-term debt capital. It provides strong evidence to indicate that debt capital has a negative impact on firm performance. The study also found a significant negative relationship between tangibility and performance indicating inefficient utilization of non-current assets. The negative performance implications associated with over-utilization of short-term debts and the under-utilization non-current assets …

Structure-Activity Relationships Of 2-Aryl-1h-Indole Inhibitors Of The Nora Efflux Pump In Staphylococcus Aureus, John Bremner, Michael Kelso, Joseph Ambrus, Kim Lewis, Anthony Ball, Gabriele Casadei Jan 2013

Structure-Activity Relationships Of 2-Aryl-1h-Indole Inhibitors Of The Nora Efflux Pump In Staphylococcus Aureus, John Bremner, Michael Kelso, Joseph Ambrus, Kim Lewis, Anthony Ball, Gabriele Casadei

Kim Lewis

The synthesis of 22 2-aryl-1H-indoles, including 12 new compounds, has been achieved via Pd- or Rh-mediated methodologies, or selective electrophilic substitution. All three methods were based on elaborations from simple indole precursors. SAR studies on these indoles and 2-phenyl-1H-indole in Staphylococcus aureus as NorA efflux pump inhibitors indicated 5-nitro-2-(3-methoxycarbonyl)phenyl-1H-indole was a slightly more potent inhibitor than the lead INF55. A promising new antibacterial lead compound against S. aureus (2-phenyl-1H-indol-5-yl)-methanol, was also found.

Carbanions: Formation, Structure And Thermochemistry, Stephen J. Blanksby, John H. Bowie Oct 2012

Carbanions: Formation, Structure And Thermochemistry, Stephen J. Blanksby, John H. Bowie

Stephen Blanksby

This chapter deals with even-electron carbanions: their formation, structure and thermochemical properties in the gas phase. There are a number of excellent reviews already available on the chemistry of carbanions: these discuss in the main, reactivity and anion molecule chemistry.1-4 In this chapter we focus primarily on the formation, structure and thermochemistry of simple hydrocarbon anions while other chapters in this encyclopaedia cover the broader aspects of carbanion chemistry (see Volume 1, “Strained Ring and Highly Basic Carbanions” and this volume, Reactions of Organic Molecules with Organic Ions: “Reactions of Anions with Carbonyl Centres: C–C Bond Forming Reactions”, and Unimolecular …


Effects Of Glycosylation On The Structure And Function Of The Extracellular Chaperone Clusterin, Elise Stewart, Andrew Aquilina, Simon B Easterbrook-Smith, D Murphy-Durland, C Jacobsen, S Moestrup, Mark Wilson Oct 2012

Effects Of Glycosylation On The Structure And Function Of The Extracellular Chaperone Clusterin, Elise Stewart, Andrew Aquilina, Simon B Easterbrook-Smith, D Murphy-Durland, C Jacobsen, S Moestrup, Mark Wilson

J. A. Aquilina

Clusterin is the first well characterized, constitutively secreted extracellular chaperone that binds to exposed regions of hydrophobicity on non-native proteins. It may help control the folding state of extracellular proteins by targeting them for receptor-mediated endocytosis and intracellular lysosomal degradation. A notable feature of secreted clusterin is its heavy glycosylation. Although carbohydrate comprises approximately 20−25% of the total mass of the mature molecule, its function is unknown. Results from the current study demonstrate that deglycosylation of human serum clusterin had little effect on its overall secondary structure content but produced a small increase in solvent-exposed hydrophobicity and enhanced the propensity …


The Effects Of Structure, Communication And Trust Between Marketing And R&D During New Product Development, Elias Kyriazis, Graham Massey Sep 2012

The Effects Of Structure, Communication And Trust Between Marketing And R&D During New Product Development, Elias Kyriazis, Graham Massey

Elias Kyriazis

The ability to effectively manage cross-functional working relationships (CFRs) during innovation is a key success factor in developing successful new products. However, empirical evidence suggests that CFRs during new product development are often problematic, resulting in extremely poor relations between managers, and the development of unsuccessful new products. This paper adds to our existing knowledge on the Marketing/R&D CFR by examining the effects of structural factors, communication behaviours, and interpersonal trust on the dependent variable perceived relationship effectiveness. Our findings reveal that trust has potent positive, direct effects on this CFR. Further, bidirectional communication and quality of communication also have …


Unmanned Aerial Vehicle (Uav) Remote Sensing For Hyperspatial Terrain Mapping Of Antarctic Moss Beds Based On Structure From Motion (Sfm) Point Clouds, A Lucieer, Sharon A. Robinson, D Turner Aug 2012

Unmanned Aerial Vehicle (Uav) Remote Sensing For Hyperspatial Terrain Mapping Of Antarctic Moss Beds Based On Structure From Motion (Sfm) Point Clouds, A Lucieer, Sharon A. Robinson, D Turner

Sharon Robinson

This study is the first to use an Unmanned Aerial Vehicle (UAV) for mapping moss beds in Antarctica. Mosses can be used as indicators for the regional effects of climate change. Mapping and monitoring their extent and health is therefore important. UAV aerial photography provides ultra-high resolution spatial data for this purpose. The aim of this study is to use Structure from Motion (SfM) techniques to generate a detailed 3D point cloud of the terrain from overlapping UAV photography.


Evidence For Specific Subunit Distribution And Interactions In The Quaternary Structure Of Α-Crystallin, Amie M. Morris, J Andrew Aquilina Jul 2012

Evidence For Specific Subunit Distribution And Interactions In The Quaternary Structure Of Α-Crystallin, Amie M. Morris, J Andrew Aquilina

J. A. Aquilina

The quaternary structure of alpha-crystallin is dynamic, a property which has thwarted crystallographic efforts towards structural characterization. In this study, we have used collision-induced dissociation mass spectrometry to examine the architecture of the polydisperse assemblies of alpha-crystallin. For total alpha-crystallin isolated directly from fetal calf lens using size-based chromatography, the alpha B-crystallin subunit was found to be preferentially dissociated from the oligomers, despite being significantly less abundant overall than the alpha A-crystallin subunits. Furthermore, upon mixing molar equivalents of purified alpha A- and alpha B-crystallin, the levels of their dissociation were found to decrease and increase, respectively, with time. Interestingly …


Hamilton And Madison Deploy ‘Constitution’ In The Federalist Papers: Semantic Values Surveyed, Peter J. Aschenbrenner May 2012

Hamilton And Madison Deploy ‘Constitution’ In The Federalist Papers: Semantic Values Surveyed, Peter J. Aschenbrenner

Peter J. Aschenbrenner

The eighty-five Federal Papers (authors James Madison and Alexander Hamilton; John Jay contributed five) are justifiably famous as elaborations of constitutional structure and text, sans citation to the convention, understandably, since secrecy imposed by Standing Order on May 28th was continued indefinitely (at the pleasure/non-action of Congress) on September 17th. Counts on semantic value/s of ‘constitution’ and ‘constitutional’ are surveyed.


Disproportional Ownership Structure And Pay–Performance Relationship: Evidence From China's Listed Firms, Jerry Cao, Xiaofei Pan, Gary Tian Apr 2012

Disproportional Ownership Structure And Pay–Performance Relationship: Evidence From China's Listed Firms, Jerry Cao, Xiaofei Pan, Gary Tian

Xiaofei Pan

This paper examines the impact of ownership structure on executive compensation in China's listed firms. We find that the cash flow rights of ultimate controlling shareholders have a positive effect on the pay–performance relationship, while a divergence between control rights and cash flow rights has a significantly negative effect on the pay–performance relationship. We divide our sample based on ultimate controlling shareholders' type into state owned enterprises (SOE), state assets management bureaus (SAMB), and privately controlled firms. We find that in SOE controlled firms cash flow rights have a significant impact on accounting based pay–performance relationship. In privately controlled firms, …


Managerial Compensation, Ownership Structure And Firm Performance In China's Listed Firms, Xiaofei Pan, Gary G. Tian, Shiguang Ma, Aelee Jun, Qingliang Tang Apr 2012

Managerial Compensation, Ownership Structure And Firm Performance In China's Listed Firms, Xiaofei Pan, Gary G. Tian, Shiguang Ma, Aelee Jun, Qingliang Tang

Aelee Jun

This paper investigates managerial compensation and its relationship with firm performance in China's listed firms. In China, the largest shareholder dominates other shareholders, controls the firm and therefore exercises substantial impacts on manager compensation. After controlling for other firm and industry characteristics, we find that manager remuneration is greater and pay-performance relation is stronger for privately-controlled firms than for state-controlled firms. We also document that state-controlled firms exercise performance-based manager incentive schemes, which is contrary to evidence found in some earlier studies. Our results also indicate that top executives in firms with a foreign ownership are more highly compensated, relative …


Managerial Ownership, Capital Structure And Firm Value, Wenjuan Ruan, Gary G. Tian, Shiguang Ma Mar 2012

Managerial Ownership, Capital Structure And Firm Value, Wenjuan Ruan, Gary G. Tian, Shiguang Ma

Shiguang Ma

This paper extends prior research to examine the managerial ownership influences on firm performance through the choices of capital structures by using a new sample of S&P 500 firm in 2005. The empirical results of OLS regressions replicate the nonlinear relationship between managerial ownership and firm value. However, we found that the turning points had moved up in our sample compared with previous papers, which implies that the managerial control for pursuing self-interest, and the alignment of interests between managers and other shareholders can only be achieved now by management holding more ownership in a firm than that found in …

Linking The Structure And Perception Of 3-D Faces: Gender, Ethnicity And Expressive Posture, Guillaume Vignali, Harold C. Hill, Eric Vatikiotis-Bateson

Harold Hill

A statistical study of human face shape is reported whose overall goal was to identify and characterise salient components of facial structure for human perception and communicative behaviour. A large database of 3-D faces has been constructed and analysed for differences in ethnicity, sex, and posture. For each of more than 300 faces varying in race/ethnicity (Japanese versus Caucasian) and sex, nine postures (smiling, producing vowels, etc) were recorded. Principal components analysis (PCA) and linear discriminant analysis (LDA) were used to reduce the dimensionality of the data and to provide simple, yet reliable reconstruction of any face from components corresponding …

Microstructure And Mechanical Properties Related To Particle Size Distribution And Composition In Dark Chocolate, Emmanuel Ohene Afoakwa, Alistair Paterson, Mark Fowler, Joselio Vieira Feb 2009

Microstructure And Mechanical Properties Related To Particle Size Distribution And Composition In Dark Chocolate, Emmanuel Ohene Afoakwa, Alistair Paterson, Mark Fowler, Joselio Vieira

Professor Emmanuel Ohene Afoakwa

Composition in dark chocolate was varied and the effects determined on microstructure, using light microscopy, and mechanical properties of molten and tempered chocolates, using a TA.HD Plus Texture Analyser. Compositional parameters were particle size distribution (PSD) (D90 of 18, 25, 35 and 50 lm), fat (25%, 30% and 35%) and lecithin (0.3% and 0.5%) contents. Micrographs revealed wide variations in sugar crystalline network structure and inter-particle interaction strengths related to PSD and fat level. Samples containing 25% fat had more crystal agglomerates, well flocculated with greater particle-to-particle interaction strengths than those with higher (30% and 35%) fat contents. Increasing the …

The Decentralization Of Collective Bargaining: A Literature Review And Comparative Analysis, Harry C. Katz Apr 2008

The Decentralization Of Collective Bargaining: A Literature Review And Comparative Analysis, Harry C. Katz

Harry C Katz

"The author reviews evidence that the bargaining structure is becoming more decentralized in Sweden, Australia, the former West Germany, Italy, the United Kingdom, and the United States, although In somewhat different degrees and ways from country to country. He then examines the various hypotheses that have been offered to explain the significant trend Shifts In bargaining power, as well as the diversification of corporate and worker Interests, have played a part in this change, he concludes, but work reorganization has been more influential still. He also explores how the roles of central unions and corporate industrial relations staffs are challenged …
