A meridional structure of static stability and ozone vertical gradient around the tropopause in the Southern Hemisphere extratropics

Abstract. An analysis of the static stability and ozone vertical gradient in the ozone tropopause based (OTB) coordinate is applied to the ozonesonde data at 10 stations in the Southern Hemisphere (SH) extratropics. The tropopause inversion layer (TIL) with a static stability maximum just above the tropopause shows similar seasonal variations at two Antarctic stations, which are latitudinally far from each other. Since the sunshine hour varies with time in a quite different way between these two stations, it implies that the radiative heating due to solar ultraviolet absorption of ozone does not contribute to the seasonal variation of the TIL. A meridional section of the static stability in the OTB coordinate shows that the static stability just above the tropopause has a large latitudinal gradient between 60° S and 70° S in austral winter because of the absence of the TIL over the Antarctic. It is accompanied by an increase of westerly shear with height above the tropopause, so that the polar-night jet is formed above this latitude region. This result suggests a close relationship between the absence of the TIL and the stratospheric polar vortex in the Antarctic winter. A vertical gradient of ozone mixing ratio, referred to as ozone vertical gradient, around the tropopause shows similar latitudinal and seasonal variations with the static stability in the SH extratropics. In a height region above the TIL, a small ozone vertical gradient in the midlatitudes associated with the Antarctic ozone hole is observed in a height region of the subvortex but not around the polar vortex. This is a clear evidence of active latitudinal mixing between the midlatitudes and subvortex.
Modeling Market Downside Volatility First Draft : March 2010 This Draft : July 2010

We propose a new methodology for modeling and estimating time-varying downside risk and upside uncertainty in equity returns and for assessment of risk-return trade-off in financial markets. Using the salient features of the binormal distribution, we explicitly relate downside risk and upside uncertainty to conditional heteroscedasticity and asymmetry through binormal GARCH (BiN-GARCH) model. Based on S&P500 and international index returns, we find strong empirical support for existence of significant relative downside risk, robust positive relationship between the relative downside risk and conditional mode, and evidence for positive expected value for the market price of risk, hence; a positive risk-return trade-off in market index returns.
Risk, Preference, Capital Structure and Incentives

Using the surplus theory of the firm, we examine capital and labor as inputs of a surplus generating firm, and study the capital structure of the firm. We derive two equilibrium models on: (a) the capital structure and ownership of the firm and (b) alternative incentive compensation structures. Within the framework of the firm as a cooperative surplus generating enterprise, we introduce the concepts of risk, preference and resource constraints, to provide a framework for analyzing more sophisticated methods of dividing the risks and rewards of the firm’s surplus.
THE INFLUENCING OF RISK FACTORS, MANAGEMENT ENTRENCHMENT,AND CORPORATE GOVERNANCE QUALITY ON EQUITY RISK PREMIUM

The purpose of this study is to examine the influencing of firm size, leverage, beta, management entrenchment, managerial ownership, and independent board on equity risk premium of indonesia public listed companies. The 70 companies were selected randomly as the samples of this study. This research found that beta, management entrenchment, managerial ownership, and independent board is positively and significantly impact on equity risk premium, while the firm size and leverage are negatively and significantly affect equity risk premium. These results indicate that the higher the ability of management to maintain their position (management entrenchment), the higher investment risk, so investors will tend to expect a higher return as well. The result also indicates that small firm more risky than large firms so that investors expect the equity risk premium is greater for small firms. Meanwhile an independent board to indicate that number of proportion of independent board at the company will lead to difficult decisions and unable to play the role to oversee the management, so the company’s risk will be increase.
Prognostic and Predictive Impact of Ki-67 in Premalignant and Malignant Squamous Cell Lesions of Oral Cavity

Introduction: Oral squamous cell carcinoma, the fifth most common cancer worldwide, is a major cause of morbidity and mortality in India. It most commonly occurs in middle-aged and older individuals. Typically, they tend to be preceded by a premalignant state for a long time. The present study evaluates the clinicopathological profile of patients with oral lesions and the role of malpractices that promote carcinogenesis in the oral mucosa and the use of Ki-67 as an important predictor of the same. Materials and methods: The expression of Ki-67 was studied in paraffin-embedded tissue sections of oral lesions of all the cases after taking a detailed history and examination. Results: The study was conducted on 65 patients with 25 dysplastic and 40 malignant lesions. Males were affected more frequently than females. The most common age group affected was 31 to 60 years with mean age of 45.4 years. Anterior twothird of tongue (41%) was the most commonly affected site. 95% of the patients had a history of addiction in form of smoking, tobacco chewing and betel nut. Out of 25 cases of dysplasia, 11 showed low expression while out of 40 cases of squamous cell carcinoma only three showed low and 29 showed high expression of Ki-67. Conclusion: The expression of Ki-67 correlates well with the disease progression from dysplasia to carcinoma of the oral cavity. It is therefore a marker of malignant transformation and carcinogenesis in oral premalignant lesions and in future it may serve as a prognostic tool in the early detection of malignancy.
Transport properties of chiral p-wave superconductor-normal metal nanostructures

Transport Properties of Chiral p-wave Superconductor-Normal Metal Nanostructures Ahmet Keles Chair of the Supervisory Committee: Professor Anton Andreev Department of Physics In this thesis, we present a theory of electron transport for unconventional superconductors. We focus on the superconducting properties of Sr2RuO4, which is a strong candidate for two dimensional p-wave superfluidity in electronic systems. We present Green function formulation of the theory of superconductivity and reduce the formulation within quasiclassical approximation. To study the systems with disordered normal metal junctions, we derive the boundary conditions of quasiclassical equations from the microscopic theory considering a spin active boundary. Boundary between normal metal and superconductor is modeled with Rashba type spin orbit coupling. An exact solution of the resulting equations are given and the resistance of the model system is calculated as a function of temperature, boundary transparency and symmetry of the superconducting state. The developed theory is used to study the phase transition of unconventional superconductors with increasing impurity concentration. It has been shown that, in the strong disordered regime, system can be modeled as Mattis model known from the theory of spin glasses. We show that with increasing disorder there will be two consecutive phase transitions: A phase transition from unconventional superconductor to s-wave superconductor followed by a transition from s-wave superconductor to normal metal. A qualitative phase diagram is prsented and corrections to Mattis model approximation is considered.
14C Level At Mt Chiak and Mt Kyeryong in Korea

We have observed A14C concentrations in the northern hemisphere temperate region in the bomb pulse period, using cross-dated tree ring samples. The tree-ring samples were taken from one 70-year-old and two 50-year-old red pines (Pinus densiflora) on Mt Chiak, Korea and from a 50-year-old red pine (Pinus densiflora) on Mt Kyeryong, Korea. Twenty-two tree-ring samples from four red pines ranging from 1950 to 2000 AD were pretreated to obtain holo-cellulose, combusted to CO2 by an element analyzer (EA) and converted to graphite for δ14C measurement using the accelerator mass spectrometry (AMS) facility at Seoul National University. Our results for δ14C showed good agreement with those measured by other researchers at similar latitudes. The observed steady decrease of δ14C from 1965 to 2000 AD is described by a single exponential function with a lifetime τ = 15.99 ± 0.43 yr. This lifetime is similar to that of the high-latitude region in Europe.
Global or Domestic? Which Shocks Drive Inflation in European Small Open Economies?

ABSTRACT We investigate which shocks drive inflation in small open economies. In the first step, we use the structural vector autoregressive (SVAR) approach to identify the global shocks. Second, we regress the disaggregated price indices for selected European economies on the global shocks controlling for the domestic variables. We find that the fluctuations of inflation in the analyzed countries are to large extent determined by the cyclical movements of the domestic output gap however the commodity shock also contributes strongly to inflation variability. The role of the non-commodity global supply shock is less prominent, however, interpreted to some extent as a globalization shock, for most of the analyzed period lowers the inflation. Nonetheless, in the aftermath of the global financial crisis, this shock reversed what may be interpreted as the weakening of the globalization process.
Stability of Two Probiotics Bacteria of Goat Milk Yoghurt in Rat Digestive Tract

Increased age will affect the bacterial population of the human digestive tract, in which many bacteria will adapt and colonize different sites. Combining probiotics and prebiotics in what has been called a synbiotic could beneficially affect the host by improving survival and implantation/adhesion of live microbial dietary supplements in the gastrointestinal flora. Probiotic bacteria are expected to survive in the digestive tract to give health effects to the host by balancing the intestinal microflora. The addition of fructo-oligosaccharides is expected to increase viability and growth of probiotics in the digestive tract. The objective of the current research is to investigate the effect of probiotic yoghurt and synbiotic yoghurt of Etawa Breed Cross Saanen (PESA) goats together with fructo-oligosaccharides, on female rats and to study the stability of probiotic bacteria in the digestive tracts. The results showed that synbiotic yoghurt intake had no significant influence (p>0.05) on ration consumption, body weight gain, feed conversion, final body weight and mortality. The synbiotic intake significantly increased the population of Bifidobacterium longum (p<0.01) and Lactobacillus acidophilus (p<0.05), but in contrast decreased (p<0.05) the population of Escherichia coli. The yoghurt synbiotic treatment over 14 days influenced probiotic bacteria’s stability as shown by the reduced population of B. longum and L. acidophilus.
Study of Surface Morphology, Elemental Composition and Origin of Atmospheric Aerosols (PM2.5 and PM10) over Agra, India

In situ measurements of PM (PM2.5 and PM10) particles were carried out using a medium volume air sampler (offline) and particle number concentrations of PM were measured by a Grimm aerosol spectrophotometer (online) during the study period of 2010–2011. The morphology and elemental composition analyses of PM were performed by Scanning Electron Microscopy (SEM) and Energy Dispersive Spectrometry (EDS), respectively. The average mass concentrations of PM2.5 and PM10 were 97.2 and 242.6 µg/m 3 at roadside (RD) and 121.2 and 230.5 µg/m 3 at a semirural (SR) site, respectively. These concentrations were substantially higher than the NAAQS, WHO and USEPA standards. The highest mass and number concentrations of PM2.5 and PM10 were observed during winter, followed by those during the post-monsoon period and summer, with the lowest in the monsoon period. SEM and EDS analysis of PM indicated the presence of soot, mineral, tarballs, fly ash, aluminosilicates/silica, fluorine, carbon rich, and Cl-Na rich particles. Of these particles, soot, tarballs, and F-C rich particles dominate in PM2.5, whereas mineral, aluminosilicates, and Cl-Na rich particles dominate in PM10. The morphology and elemental composition of the particles varied over the seasons due to atmospheric processing. The highest carbon concentration (56%) was observed in PM2.5 during summer at the RD, while in the monsoon, postmonsoon period and winter the carbon concentration was ~9% lower at the RD as compared to the SR. However, the concentration of carbon in PM10 was ~38% higher at the RD as compared to SR during both summer and winter. Air mass backward trajectory cluster analysis was performed, and the results indicate that the aerosol loadings over Agra are mainly transported from the Middle East and Arabian Sea during the summer and monsoon period, while during the pre-monsoon period and winter the aerosol loadings came from the northern region, and were due to the burning of biomass and coal, as well as other local activities.
Disk Masses for Embedded Class I Protostars in the Taurus Molecular Cloud

Class I protostars are thought to represent an early stage in the lifetime of protoplanetary disks, when they are still embedded in their natal envelope. Here we measure the disk masses of 10 Class I protostars in the Taurus Molecular Cloud to constrain the initial mass budget for forming planets in disks. We use radiative transfer modeling to produce synthetic protostar observations and fit the models to a multi-wavelength data set using a Markov Chain Monte Carlo fitting procedure. We fit these models simultaneously to our new Combined Array for Research in Millimeter-wave Astronomy 1.3 mm observations that are sensitive to the wide range of spatial scales that are expected from protostellar disks and envelopes so as to be able to distinguish each component, as well as broadband spectral energy distributions compiled from the literature. We find a median disk mass of on average, more massive than the Taurus Class II disks, which have median disk mass of . This decrease in disk mass can be explained if dust grains have grown by a factor of 75 in grain size, indicating that by the Class II stage, at a few Myr, a significant amount of dust grain processing has occurred. However, there is evidence that significant dust processing has occurred even during the Class I stage, so it is likely that the initial mass budget is higher than the value quoted here.
The human capital roots of the middle income trap: the case of China

China, like other middle income countries, is facing the challenges of the next stage of development as its leaders seek to guide the nation into becoming a high income country. At this same point of development, however, other countries have faltered, raising the possibility of stagnation or collapse. The stagnation of growth after reaching a level of income high enough to be call “middle income” is a phenomenon which some observers call the Middle Income Trap. In this paper we explore one of the major challenges that nations, including China, must face in the transition from middle to high income: the management of inequality. In particular, we explore the possible roots of future inequality that is associated with a nation’s underinvestment in the human capital of broad segments of its population. To meet this goal we first look at several benchmarks of successful transitions from middle to high income (e.g., the case of South Korea) and not-so-successful transitions (Mexico). We then exam more systematically the characteristics of countries that have successfully transitioned (or graduated) from middle to high income (Graduates) and those that are attempting to do so now (Aspirees). With this background, we describe the challenges that China faces in the light of rising wage rates and highly unequal income distribution today. We also document the high levels of human capital inequality in China today, a harbinger of high future inequality. In discussing the sources of the human capital inequality, in addition to the structural and institutional barriers that are discouraging many students (and their parents) from staying in school to achieve the levels of learning that we believe are necessary for preparing individuals for employment in the coming decades, we also identify severe nutritional and health problems. We believe that these nutrition and health problems, unless addressed, are creating serious China’s human capital deficiencies in poor areas of rural China and locking in decades of hard-to-address inequality. The paper ends with a call for leaders in China (and countries at the same level of income of China) to launch immediately a war on poor education, health and nutrition as one step in helping such nations avoid the Middle Income Trap in the future.
How to strengthen the European Semester

The emphasis of the European Semester should shift from economic policy coordination – intended as the process through which member states commit to common rules and recommendations adopted by the Council of the European Union under the surveillance of the European Commission – to a stronger national ownership. Coordination of national policies may be essential at times of crisis, when cross-country spillover effects tend to be large, but it may not be very effective when economic conditions return to normal, as spillovers tend to be small and the incentives for governments to coordinate are diminished. Stronger national ownership should lead to better enforcement of commonly agreed rules, regardless of economic conditions and remove the perception that rules are hierarchically imposed. National ownership could be improved by involving the national fiscal councils and the national productivity boards explicitly in the elaboration of EU recommendations for national governments. This should be done without increasing the complexity of an already complicated EU governance system of governance or damaging their reputation as independent bodies. Reforms aimed at improving the structural functioning of EU’s economies are of critical importance for member states, yet the reasons why specific reforms should be embedded in the Semester are not always clear. Moreover, strengthening the Semester by further linking the EU budget to reforms undertaken in the member states is fine in theory but very difficult to implement in practice. Reforms cannot be ‘bought’ as such and it would be extremely difficult to measure the implementation of so-called country-specific recommendations (CSRs) with sufficient precision to make implementation a condition for funds. The primary role of the Commission should remain to foster coordination in case of economic crisis and to provide technical support for reforms when needed.
Microwave cavity searches for dark-matter axions

Recent determinations of cosmological parameters point to a flat Universe, whose total energy density is composed of about two-thirds vacuum energy and one-third matter. Ordinary baryonic matter is relegated to a small fraction of the latter, within which the luminous part is an order of magnitude smaller yet. Particle dark matter, i.e., one or more relic particle species from the big bang, is thus strongly suggested as the dominant component of matter in the Universe. The axion, a hypothetical elementary pseudoscalar arising from the Peccei-Quinn solution to the strong-CP problem, is a well-motivated candidate. If the axion exists, it must be extremely light, in the mass range of 1026 – 1023 eV, and possess extraordinarily feeble couplings to matter and radiation. Nevertheless, as proposed by Sikivie in 1983, the axion’s two-photon coupling lends itself to a feasible search strategy with currently available technology. In this scheme, axions resonantly convert to single microwave photons by a Primakoff interaction, in a tunable microwave cavity permeated by a strong magnetic field. Present experiments utilizing heterostructure transistor microwave amplifiers have achieved total system noise temperatures of ;3 K and represent the world’s quietest spectral radio receivers. Exclusion regions have already been published well into the band of realistic axion model couplings, within the lowest decade of mass range. Recent breakthroughs in the development of near-quantum-limited superconducting quantum interference device amplifiers should reduce the system noise temperature to ;100 mK or less. Ongoing research into using Rydberg-atom single-quantum detectors as the detector in a microwave cavity experiment could further reduce the effective noise temperature. In parallel with improvements in amplifier technology, promising concepts for higher-frequency cavity resonators are being explored to open up the higher decades in mass range. Definitive experiments to find or exclude the axion may therefore be at hand in the next few years. As the microwave cavity technique measures the total energy of the axion, a positive discovery could well reveal fine structure of the signal due to flows of nonthermalized axions. Manifesting diurnal and sidereal modulation, such detailed features would contain a wealth of information about the history, structure, and dynamics of our Milky Way galaxy.
An Assessment of Customers Readiness, Loyalty and Satisfaction on E - Banking Services: A Nigerian Perspective

Despite the importance of electronic banking in many financial institutions, fewer studies have focused on customers’ satisfaction and customers readiness especially in an African setting. With the recent development in the information and technology world many customers have embraced e-banking. In this study, we measured the effect of customers’ readiness, loyalty and satisfaction on electronic banking services. We majorly used questionnaire that was designed on a 5-point scale to be able to collect good quantitative data. This study established that there is a significantly positive relationship between electronic banking readiness and customer’s satisfaction. The study recommended that more emphasis and efforts be laid on targeting individual clients, a more persuasive promotion of the e-banking should be conducted more regularly and banks should ensure nothing interrupts the flow of service delivery. In addition, electronic banking service providers ought to look out for indicators of innovative ways of creating awareness about the service through participation in trade organizations, exhibitions as well as adoption of new technologies on internet banking.
