Momentum effects in the largest twenty Australian and fifteen New Zealand shares are analyzed. In the medium term, past winners continue to outperform past losers. The results are statistically significant for both countries and across various ranking and holding periods. A practical long/short investment strategy was back tested and proven to be economically profitable over the last decade.
Liquidity Effects due to Information Costs from Changes in the FTSE 100 List

In this paper we examine effect on the returns of firms that have been included to and deleted from the FTSE 100 over the time period of 1984-2001. Like the S&P 500 listing studies, we find that the price and trading volume of newly listed (deleted) firms increases (decreases). The evidence is consistent with the information cost/liquidity explanation. This is because investors hold stocks with more (less) available information, consequently implying that they have lower (higher) trading costs. This explains the increase (decrease) in the stock price and trading volume of newly listed (deleted) stocks to (from) the FTSE 100 List.
Lattice Boltzmann simulations of contact line motion in a liquid-gas system

We use a lattice Boltzmann algorithm for liquid-gas coexistence to investigate the steady-state interface profile of a droplet held between two shearing walls. The algorithm solves the hydrodynamic equations of motion for the system. Partial wetting at the walls is implemented to agree with Cahn theory. This allows us to investigate the processes which lead to the motion of the three-phase contact line. We confirm that the profiles are a function of the capillary number and a finite-size analysis shows the emergence of a dynamic contact angle, which can be defined in a region where the interfacial curvature tends to zero.
A Project Task Coordination Model for Team Organization in Concurrent Engineering

In a concurrent engineering environment, product design needs to simultaneously consider various downstream activities throughout the entire product life cycle, in addition to meeting the functional requirements of the products. To accomplish this, multifunctional design teams are organized with team members from different functional departments interacting in every phase of development tasks. However, without proper task coordination and team organization, communication and cooperation among a large number of dependent or interdependent tasks and team members could seriously delay project completion. This calls for the intention of this research to study the underlying structure of the project tasks. The objectives of this research are: (1) to develop a project task coordination model that identifies the sequence of all project tasks and reveals the underlying structure of the design process; (2) to decompose large interdependent task groups into smaller and manageable task groups by transforming the binary form of task relationships into the quantifiable task coupling strength and (3) to provide a structural foundation for the efficient team organization in concurrent engineering. Design Structure Matrix (DSM) is used to represent relationship among project tasks. Analytic Hierarchy Process (AHP), as a multi-criteria decision analysis, is employed to quantify the binary DSM. The effectiveness of this model is demonstrated by an illustrative example. The result shows that our proposed model is not only capable of coordinating the entire project tasks but also helpful in organizing project teams.
AUSTRALIAN Halobacteria and THEIR RETINAL‐PROTEIN ION PUMPS *

Abstract– Halophiles collected in Western Australia have been found to be examples of extremely halophilic rod‐shaped archaebacteria, members of the genus Halobacterium. Most of them contain retinal proteins, and these proteins differ from one another and also from both bacteriorhodopsin (bR) and halorhodopsin [and sensory rhodopsins (sR)] isolated from Halobacterium salinarium (halobium), as revealed by their peptide maps and amino acid sequences. However, these retinal proteins still have the ability to pump protons or chloride ions in the light. These new ion pumps, designated archaerhodopsins (aR) [Mukohata et al. (1988) Biochem. Biophys. Res. Commun.151,1339–1345], are almost identical in terms of their molecular sizes and transient photochemical properties to the ion pumps identified previously. Differences are found in the: (1) apparent extinction coefficient of dark/light‐adapted aR‐2; (2) titration profiles at acidic pH of the absorption spectra of all aRs; and (3) circular dichroism spectra, which are influenced by the coexistent isoprenoid bacterioruberin. The amino acid sequences of two proton pumps from the Australian halobacteria, namely aR and aR‐2, are approximately 90% homologous and both sequences are about 60% homologous with that of bR. Hydropathy plots suggest that these pumps also have a seven‐helical structure similar to that of bR. The amino acid residues are highly conserved in the helical regions, in particular in the case of helices C and G (91 and 84%, respectively), among the three proton pumps.
Nonparametric Tests for Homogeneity of Species Assemblages: A Data Depth Approach

Summary Testing homogeneity of species assemblages has important applications in ecology. Due to the unique structure of abundance data often collected in ecological studies, most classical statistical tests cannot be applied directly. In this article, we propose two novel nonparametric tests for comparing species assemblages based on the concept of data depth. They can be considered as a natural generalization of the Kolmogorov–Smirnov and the Cramér‐von Mises tests (KS and CM) in this species assemblage comparison context. Our simulation studies show that the proposed test is more powerful than other existing methods under various settings. A real example is used to demonstrate how the proposed method is applied to compare species assemblages using plant community data from a highly diverse tropical forest at Barro Colorado Island, Panama.
Outcome of lupus nephritis in Indian children

We report the clinicopathological features, treatment and outcome of 54 Indian children (14 boys) with biopsy-proven lupus nephritis followed over a 10-year period. The mean age (SD) at onset of disease was 9.6 ± 2.6 (range 2.5–14.4) years. Twenty-six (48.1%) patients had class IV nephritis, 7 (13.0%) had class V, whereas class I, II and III nephritis were present in 3 (5.6%), 10 (18.5%) and 6 (11.1%) patients, respectively. Hypertension, haematuria and nephrotic range proteinuria were present in 30 (55.6%), 31 (57.4%) and 28 (51.8%) patients, respectively. Compared with all the other classes combined, there were more boys among patients with class IV nephritis, and hypertension, haematuria, nephrotic syndrome and decreased glomerular filtration rate at presentation were more common. The mean duration of follow-up was 3.1 ± 2.9 years (median 2.5, range 0.2–10.3 years). Of the 39 patients who were followed-up for at least 1 year, 33 (84.6%) were in complete or partial remission, whereas six (15.4%) had no response to therapy. The incidence of serious infection was 1.5 episodes per 10 patient-years. Nine patients died, of whom four had serious infections or septicaemia, and three developed end-stage renal failure (ESRF). The patient survival rate at 3 years and at last follow-up visit was 88% and 83.3%, respectively, whereas the renal survival rates (without ESRF) were 92% and 94.4% respectively. Cox regression analysis showed no relation of gender, age of onset, presence of hypertension, haematuria and proteinuria, estimated glomerular filtration rate, renal histology and response to therapy to the outcome of death or ESRF. We found lower patient survival rate as compared with data from the developed countries but similar to that seen in developing countries. Serious infections were an important cause of mortality besides renal failure.
Ab initio conformational analysis of nucleic acid components: Intrinsic energetic contributions to nucleic acid structure and dynamics

In recent years, the use of high‐level ab initio calculations has allowed for the intrinsic conformational properties of nucleic acid building blocks to be revisited. This has provided new insights into the intrinsic conformational energetics of these compounds and its relationship to nucleic acids structure and dynamics. In this article we review recent developments and present new results. New data include comparison of various levels of theory on conformational properties of nucleic acid building blocks, calculations on the abasic sugar, known to occur in vivo in DNA, on the TA conformation of DNA observed in the complex with the TATA box binding protein, and on inosine. Tests of the Hartree–Fock (HF), second‐order Møller–Plesset (MP2), and Density Functional Theory/Becke3, Lee, Yang and Par (DFT/B3LYP) levels of theory show the overall shape of backbone torsional energy profiles (for γ, ε, and χ) to be similar for the different levels, though some systematic differences are identified between the MP2 and DFT/B3LYP profiles. The east pseudorotation energy barrier in deoxyribonucleosides is also sensitive to the level of theory, with the HF and DFT/B3LYP east barriers being significantly lower (∼2.5 kcal/mol) than the MP2 counterpart (∼4.0 kcal/mol). Additional calculations at various levels of theory suggest that the east barrier in deoxyribonucleosides is between 3.0 and 4.0 kcal/mol. In the abasic sugar, the west pseudorotation energy barrier is found to be slightly lower than the east barrier and the south pucker is favored more than in standard nucleosides. Results on the TA conformation suggest that, at the nucleoside level, this conformation is significantly destabilized relative to the global energy minimum, or relative to the A‐ and B‐DNA conformations. Deoxyribocytosine would destabilize the TA conformation more than other bases relative to the A‐DNA conformation, but not relative to the B‐DNA conformation. © 2002 Wiley Periodicals, Inc.

The Bright Side of Product Market Threats: The Case of Innovation

This paper examines the effects of predatory strategies from rivals on firm innovation. Using Hoberg, Phillips and Prabhala’s (2014) product market fluidity to capture competitive threats from rivals, we find that firms with high product market threats invest more in R&D and generate higher number of patents and patent citations. Using shifts in import tariffs as a quasi-natural experiment to detect the exogenous shocks to competition, we show that firms with high competitive threats tend to be more innovative following the shocks. We further document that the effects of product market threats on innovation are more pronounced for firms with smaller market shares or firms in more competitive industries. Overall, our results are consistent with the hypothesis that product market threats create incentives for firms to innovate to “escape competition. ”
Rotavirus Activates JNK and p38 Signaling Pathways in Intestinal Cells, Leading to AP-1-Driven Transcriptional Responses and Enhanced Virus Replication

ABSTRACT Rotavirus infection is known to regulate transcriptional changes in many cellular genes. The transcription factors NF-κB and AP-1 are activated by rotavirus infection, but the upstream processes leading to these events are largely unidentified. We therefore studied the activation state during rotavirus infection of c-Jun NH2-terminal kinase (JNK) and p38, which are kinases known to activate AP-1. As assessed by Western blotting using phospho-specific antibodies, infection with rhesus rotavirus (RRV) or exposure to UV-psoralen-inactivated RRV (I-RRV) resulted in the activation of JNK in HT-29, Caco-2, and MA104 cells. Activation of p38 during RRV infection was observed in Caco-2 and MA104 cells but not in HT-29 cells, whereas exposure to I-RRV did not lead to p38 activation in these cell lines. Rotavirus strains SA11, CRW-8, Wa, and UK also activated JNK and p38. Consistent with the activation of JNK, a corresponding increase in the phosphorylation of the AP-1 component c-Jun was shown. The interleukin-8 (IL-8) and c-jun promoters contain AP-1 binding sequences, and these genes have been shown previously to be transcriptionally up-regulated during rotavirus infection. Using specific inhibitors of JNK (SP600125) and p38 (SB203580) and real-time PCR, we showed that maximal RRV-induced IL-8 and c-jun transcription required JNK and p38 activity. This highlights the importance of JNK and p38 in RRV-induced, AP-1-driven gene expression. Significantly, inhibition of p38 or JNK in Caco-2 cells reduced RRV growth but not viral structural antigen expression, demonstrating the potential importance of JNK and p38 activation for optimal rotavirus replication.
Disclosure ambiental: uma análise do conteúdo dos relatórios ambientais de empresas do setor de papel e celulose em nível internacional

Analysis of the content of the companies' environmental reports of the pulp and paper industry in international level. The objective of this research is to investigate, based on the annual and environmental reports currently practiced, how the environmental information disclosure level presented by the companies of the pulp and paper industry is. The literature review presents the main aspects related to the environmental disclosure and accounting, the regulations and guidelines about environmental reports, as well as a summary of several researches on environmental reports and disclosures. Analysis of the reports contents of 42 of the 50 larger companies, for sales in the pulp and paper industry worldwide, as well as of eight of the ten larger Brazilian companies of this sector are performed. The findings sustain the thesis that disclosure of environmental information presented by the companies of the pulp and paper industry diverge from company to company regarding size, country location and type of report (financial or specific), being incipient and fragile as far as information reliability and comparability is concerned. One can also conclude that: a) most environmental information of companies in this sector is made evident in specific environmental reports, being this information practically descriptive; b) the country where the company is located interferes in the level of disclosure in the pulp and paper industry; c) the bigger the company, the more detailed is the presentation of the disclosure of the environmental information; and d) the level of environmental disclosure of the Brazilian pulp and paper companies is less detailed than the average level of disclosure of companies of the same sector in other countries. New issues for studies and further investments to develop empiric researches in environmental disclosure and accounting are suggested. The result of this study is restricted to the sample analyzed.
Household Risk Management in Rural and Urban Thailand

This paper examines the nature of risk faced by households in Thailand and the strategies that these households adopt to mitigate the adverse effect from income shortfalls. I use a new cross-section dataset that is based on a sample of both urban and rural households. I find that price shock is the most prevalent source of income shortfalls. I also find that the most common risk-mitigating strategy employed by households is to borrow from the Village Fund. Nonetheless, there is a high degree of heterogeneity among households, especially in terms of their sources of income and this plays a key role in determining how a household responds to shocks. Thus, it may not be advisable to design policy based on the paradigm of a representative consumer.
A Re-Examination of the Conglomerate Merger Wave in the 1960s: An Internal Capital Markets View

One possible explanation for bidding firms earning positive abnormal returns in diversifying acquisitions in the 1960s is that internal capital markets were expected to overcome the information deficiencies of the less-developed capital markets. Examining 392 bidder firms during the 1960s, we find the highest bidder returns when financially "unconstrained" buyers acquire "constrained" targets. This result holds while controlling for merger terms and for different proxies used to classify firms facing costly external financing. We also find that bidders generally retain target management, suggesting that management may have provided company-specific operational information, while the bidder provided capital-budgeting expertise.

Clinical Implications of the Technetium-99m Stannous Pyrophosphate Myocardial Scintigraphic "Doughnut" Pattern in Patients with Acute Myocardial Infarcts

Forty-five patients with acute myocardial infarcts had technetium-99m stannous pyrophosphate (9"mTc-PYP) myocardial scintigrams with radionuclide uptake localized to the anterior or lateral wall of the left ventricle in a pattern resembling a doughnut (intense peripheral uptake and relatively less central uptake). Sixty-seven percent of these patients developed left ventricular failure with infarction. Twenty-six patients with acute anterior or lateral myocardial infarcts were selected for comparison because of 9OmTc. -PYP scintigrams which were more homogeneously positive. There were no significant differences in age, sex or electrocardiographic location of infarction. In-hospital left ventricular failure in Killip classes II, III or IV was more common in the group with doughnut scintigrams. Estimates of infarct size by scintigraphic planimetry and analysis of peak serum creatine kinase levels indicated larger infarcts in the group with doughnut scintigrams.A doughnut "mTc-PYP myocardial scintigraphic pattern identifies a relatively large myocardial infarct that is probably associated with developing or worsening left ventricular failure. Further knowledge of the factors determining the development of this, rather than other scintigraphic abnormalities, and of the mechanism of filling in of the central defect of this doughnut in some patients, may help us understand certain aspects of the pathophysiology of acute myocardial infarcts.
Strong and Weak Error Estimates for Elliptic Partial Differential Equations with Random Coefficients

We consider the problem of numerically approximating the solution of an elliptic partial differential equation with random coefficients and homogeneous Dirichlet boundary conditions. We focus on the case of a lognormal coefficient and deal with the lack of uniform coercivity and uniform boundedness with respect to the randomness. This model is frequently used in hydrogeology. We approximate this coefficient by a finite dimensional noise using a truncated Karhunen-Loeve expansion. We give estimates of the corresponding error on the solution, both a strong error estimate and a weak error estimate, that is, an estimate of the error commited on the law of the solution. We obtain a weak rate of convergence which is twice the strong one. In addition, we give a complete error estimate for the stochastic collocation method in this case, where neither coercivity nor boundedness is stochastically uniform. To conclude, we apply these results of strong and weak convergence to two classical cases of covariance kernel choices, the case of an exponential covariance kernel on a box and the case of an analytic covariance kernel, yielding explicit weak and strong convergence rates.
Physical activity patterns among walkers and compliance with public health recommendations.

PURPOSE Walking is the most common leisure-time physical activity (LTPA) among U.S. adults. The purpose of this study was to estimate the prevalence of walking for physical activity and the proportion of walkers who met current public health physical activity recommendations. METHODS We analyzed data from the 1998 Behavioral Risk Factor Surveillance System, a collection of state-based, random-digit-dialed telephone surveys of adults. Physical activity measures included the type, frequency, and duration of the two LTPAs in which respondents engaged most often during the previous month. We calculated the prevalence of walking and the prevalence of three physical activity patterns defined by combinations of walking duration and frequency. We also examined the effect on these patterns of participating in a second LTPA. RESULTS In 1998, an estimated 38.6% of U.S. adults walked for physical activity. Among walkers, 21.3% walked a minimum of 30 min five or more times per week. This approximates compliance with current physical activity recommendations. Compliance increased to 34.5% when the criteria were relaxed to include at least 150 min of walking per week accumulated over three or more occasions. Relaxing the criteria further to include a minimum of 150 min.wk(-1) regardless of frequency produced only a small increase in compliance (37.6%). However, compliance with each of these three activity patterns approximately doubled when a second LTPA was taken into account. CONCLUSIONS Less than 40% of walkers complied through walking with even our most liberal physical activity pattern (> or =150 min.wk(-1) regardless of frequency). For walkers to meet current public health recommendations, many need to walk more frequently and/or to engage in additional physical activities.

Photosensitive Full-Swing Multi-Layer MoS2 Inverters With Light Shielding Layers

Multi-layered MoS2 inverters with light shielding layers were fabricated and demonstrated for application in highly sensitive photodetectors, exploiting the particular advantages of an atomically thin layer and a sizable electrical bandgap. The photoleakage behaviors of the inverters under changing wavelengths of light were experimentally demonstrated to occur in a controlled manner and were analytically validated by load-line analysis. When the inverters were operated with a depletion load in the light of blue light emitting diodes, the low noise margin and transition width were significantly enhanced, by approximately 20% and 220%, respectively, as compared with those of the inverters in the dark.
