The Japan Stock Split Bubble and the Livedoor Shock

Livedoor, a famous Japanese IT company, experienced rapid growth through the overuse of a stock split strategy. Because of this strategy, the company faced a criminal investigation for suspicion of account rigging in January 2006. In this paper, I examine whether the Japanese stock split bubble burst not only because of system reform to make newly issued shares tradable on their ex-dates, but also because of the Livedoor shock. To explore this possibility, I evaluated data that were classified into specific categories: stock splits under the old system’s conditions that prevented the trade of newly issued shares for about 50 days following the ex-date, stock splits under the new system’s conditions, and news announced before and after the Livedoor shock. I estimated abnormal returns for each stock on their respective announcement dates. Results demonstrate that under the old system, trading restrictions for newly issued shares caused increases in stock prices, but the Livedoor shock stalled these increases for split stocks. These results suggest that the stock split bubble burst not only because of system reform but also because of changes in investor sentiment with regard to split stocks.
The compound 33i,a new sirt2 inhibitor, as a potential treatment for Alzheimer's disease

Alzheimers disease (AD) is the most common form of dementia and one of the leading causes of morbidity and mortality in the aging population. Although its exact etiology remains to be elucidated, it is likely to result from complex interactions between genetic, epigenetic, and environmental factors, with age as the main risk factor. Therefore, understanding the changes and alterations that occur during aging is essential to understand the aetiology of AD and to establish new pharmacological therapies. In this line, several studies have identified a major role for the histone deacetylase SIRT2 in aging and different neurodegenerative diseases, including AD. Among all sirtuins, SIRT2 expression is found strongest in the brain. Although its biological functions are not well described yet, mounting evidence indicates that excess of SIRT2 might be deleterious to neurons; hence its inhibition is postulated as a novel promising therapeutic strategy to tackle a wide variety of hallmarks that are altered during aging and neurodegenerative diseases. Based on the observations previously mentioned, the overarching objective of this study is to investigate SIRT2 inhibition as a future potential treatment for AD. For this, a preliminary in vitro toxicological evaluation was performed, followed by an extensive pharmacological study of the compound 33i, a new potent SIRT2-selective inhibitor. More precisely, the specific aim of this study is to propose the 33i molecule as a pharmacological strategy to prevent, improve or even reverse the functional and molecular alterations in two different mouse models of AD representing the sporadic and familial forms of the disease. Results show that 33i treatment was effective, through the modulation of glutamate receptors and neuroinflammation, when SIRT2 was inhibited in animals that presented an early pathology. From this perspective, this pharmacological strategy could be an ideal novel target to prevent age-related cognitive decline and neurodegeneration. In summary, given its efficacy and safety, the 33i compound seams a good pharmacological strategy to treat AD. Altogether, 33i has proved to be effective since it improves the cognitive deficit in two different AD mouse models, increases different glutamate subunit receptors, prevents the neuroinflammation when administered at early stages of the disease in the SAMP8 model and reduces the amyloid pathology in the APP/PS1 model. In addition, the lack of mutagenicity or genotoxicity observed in vitro after 33i treatment makes this molecule a promising safe epigenetic pharmacological drug.
Monetary and Fiscal Policy in a Monetary Union under the Zero Lower Bound constraint

This paper explicitly models strategic interaction between two independent national fiscal authorities and a single central bank in a simple New Keynesian model of a monetary union. Monetary policy is constrained by the zero lower bound on nominal interest rates. Coordination of fiscal policies does not always lead to the best welfare effects. It depends on the nature of the shocks whether governments prefer to coordinate or not coordinate. The size of the government multipliers depend on the combination of the intraunion competitiveness parameters. They get larger in case of implementation lags of fiscal policy.

Perceived Service Quality in Restaurant Services: Evidence from Mauritius

The purpose of this study is to investigate service quality dimensions in retsuarant services. The study examines the influence of the service dimensions on customer satisfaction and behavioral intentions within the restaurant context in an island economy, Mauritius. Factor analysis was performed to determine dimensions that are likely to influence customersâ€™ restaurant service evaluations. Based on the analyses, three distinct dimensions were identified by the customers, Food Quality-Reliability, Responsiveness-Assurance-Empathy and Tangibles. Multiple regression analyses were then employed to examine the relative importance of the three service dimensions in determining satisfaction judgments and customersâ€™ behavioral intentions. The results support the links between service quality dimensions, satisfaction and behavioral intentions respectively. The findings are expected to help the owners of restaurants in Mauritius to address the gaps and improve satisfaction level of their customers, thereby bringing about repeat business and improving profits
Brie: A Specialized Trie for Concurrent Datalog

Modern Datalog engines are employed in industrial applications such as graph databases, networks, and static program analysis. To cope with the vast amount of data in these applications, Datalog engines must employ specialized parallel data structures. In this paper, we introduce the Brie, a specialized data structure for high-density relations storing large data volumes. It effectively compresses dense data in a lock-free fashion and obtains up to 15× higher performance in parallel insertion benchmarks compared to state-of-the-art alternatives. Furthermore, when integrated into a Datalog engine running an industrial points-to analysis, runtime improves by a factor of 4× with a compression ratio of up to 3.6× are obtained.
The Desirability of Multi-equational Approaches for the Study of Economic Growth. An Empirical Evidence

This paper looks at the growth of a varied sample of countries during the period 1985-2000, focusing on three key variables: investment in physical capital, human capital and institutions. The analysis pays special attention to the process of the accumulation of these variables and their interrelationships. The results show that empirical research on growth should highlight the aspects of the accumulation and interrelationships of factors through the use of systems of equations such as that proposed in this study.
Population dynamics of cotton phylloplane bacteria antagonistic towards Xanthomonas campestris pv. malvacearum

A cotton phylloplane bacteria (PI b) belonging to genus Pseudomonas was selected for intensive studies on the basis of its in vitro antagonistic activity against the most predominant and virulent race of Xanthomonas campestris pv. maLvacearum, the bacterial blight pathogen of cotton. Plb-29 was chosen for its multiplication ability on some Gossypium hirsutum genotypes. On G. ltirsutum lines viz., Acala-44, Stoneville 2B-S9, Stoneville 20 and I-lOB, Plb-29 could multiply both in presence and absence of pathogen. It was capable of reducing pathogen population drastically when co-inoculated with the pathogen by multiplying and heavily colonising the active multiplication sites of cotton leaves.
UVCS Observation of Sungrazer C/2001 C2: Possible Comet Fragmentation and Plasma-Dust Interactions

In this paper we analyze SOHO Ultraviolet Coronagraph Spectrometer (UVCS) observations of the sungrazing comet C/2001 C2, a member of the Kreutz family, observed on 2001 February 7 at heliocentric distances of 4.98 and 3.60 R☉. This comet apparently went through sequential fragmentation events along its path: further indication of fragmentation processes is provided by UVCS observations, which show the presence of two separate tails in the 4.98 R☉ data set, which we interpret as two fragments unresolved by LASCO images, one of which sublimates before reaching 3.60 R☉. The cometary hydrogen Lyα signal, decaying exponentially with time, has been interpreted in terms of the H2O outgassing rate and the interactions of coronal protons with atoms created by the photodissociation of water. However, one of the fragments shows an additional Lyα contribution, constant with time, which adds to the temporally decaying signal. This contribution has been ascribed to the sublimation of pyroxene dust grains, whose end products neutralize coronal protons via charge exchange processes. Hence, the two fragments have different composition; differences throughout the comet body may have been the primary cause for the comet fragmentation.
The Misperception of Psychopathology: Problems With the Norms of the Comprehensive System for the Rorschach

The norms of the Comprehensive System (CS) for the Rorschach have been praised for their scientific and clinical value. However, recent findings by Shaffer, Erdberg, and Haroian suggest that the CS norms are inaccurate. We examined 14 CS variables in 32 studies of non-patient adults. The participants in these studies exhibited statistically and clinically significant differences from CS nonpatient norms for all 14 variables. Overall, nonpatient adults tended to appear pathological when compared with the CS norms. The implications of these findings for misdiagnosis and the misperception of psychopathology are discussed. Use of the CS norms in clinical or forensic settings is inadvisable. Commonly held beliefs about the validity of CS variables are likely to be false and in need of revision.
THE RELATIONSHIP BETWEEN PERSONALITY TRAITS AND LEARNING STYLES: A CLUSTER ANALYSIS

The aim of this study is to identify the relationship between personality types of college students and their learning styles. The total population of the study is composed of 421 undergraduate students from University of Gaziantep. The Big Factor Personality Inventory and Kolb’s Learning Styles Inventory III were used as the research tools. Participants’ personality traits, dispersion levels of their learning styles and the relationships between these two variables were measured by using Kmeans cluster, percentage and frequency and chi-square analysis respectively. The results of the cluster analysis suggested two different personality profiles and the participants appeared to be equally distributed into these two groups. In terms of learning styles, it was noticed that the majority of the participants adopted assimilating and diverging learning styles. The results revealed a meaningful relationship between learning styles and personality profiles.
Evaluation of Tests of Perceptual Speed/Accuracy and Spatial Ability for Use in Military Occupational Classification

With the exception of Assembling Objects (AO), a spatial ability test used only by the Navy in enlisted occupational classification, the Armed Services Vocational Aptitude Battery (ASVAB) is academic and knowledge-based, somewhat limiting its utility for occupational classification. This article presents the case for integrating the AO test into military classification composites and for expanding the breadth of ASVAB content by including a former ASVAB speed/accuracy test, Coding Speed (CS). Empirical evidence is presented that shows AO and CS (a) increment the validity of the ASVAB in predicting training grades for a broad array of occupations, (b) reduce adverse impact defined as test score barriers for women and minorities, and (c) improve classification in terms of matching recruits to occupations. Some cognitive theory is presented to support AO and CS, as well as nonverbal reasoning and working memory tests for inclusion in or adjuncts to the ASVAB.
Role of bladder washing cytology with fresh voided urine cytology in the diagnosis of urothelial malignancy

Background: Bladder cancer is one the most common lesion treated by urologists. Since decades cystoscopy has been the gold standard for the diagnosis of primary and recurrent urothelial cancers. Exfoliative urinary cytology of fresh voided urine and bladder washings is usually performed to preceding or to complement cystoscopy. This study aims to determine the role of exfoliative cytology of fresh voided urine and bladder washings in the diagnosis of primary and recurrent urothelial malignancy and to compare the diagnostic efficacy (sensitivity, specificity) of bladder washings cytology with voided urine cytology in the diagnosis of urothelial carcinoma. Patients and methods: The study was performed in the department of Pathology, Allama Iqbal Medical College, Lahore in collaboration with the department of Urology, Jinnah Hospital, Lahore. Sixty patients of both genders above 45 years of age presenting with painless hematuria, imaging evidence of urinary bladder lesion or recurrent tumor were included. Fresh voided urine and bladder washings were obtained in all the cases and cytology was performed. Results: The sensitivity of voided urine cytology and was 94.7% and specificity 33.3% with positive predictive value of 96.4% and negative predictive value of 25%. The accuracy was calculated as 91.6%. The sensitivity, specificity, positive predictive value and negative predictive value for bladder washing cytology were 94.7%, 33.3%, 96.4% and 25% respectively. The accuracy for bladder washing cytology was the same as that of the fresh voided urine cytology (91.6%). Conclusion: Fresh voided urine cytology in patients with painless hematuria is a noninvasive, cost effective and readily available tests to detect the presence of any malignancy before further invasive work up. The fresh voided urine cytology and bladder washing cytology revealed same sensitivity, specificity and predictive values so noninvasive cytology of fresh voided urine may be recommended over bladder washing cytology which is an invasive procedure. urothelial tumor if superadded infection or any reactive atypia is present. It can be reported as suggestive or suspicious for low grade malignancy if the clinical history and radiologic investigations support a vesicle growth.
Computer Modeling of Binary Dipolar Monolayers

We investigated the structural and dynamic properties of so-called binary dipolar monolayers (BDM). BDMs are planar colloidal systems containing two sorts of particles which have a permanent or induced dipole moment. The direction of the dipole moment of the particles is fixed to be perpendicular to the plane of motion and has opposite orientation for the two components. The goal of our work was to carry out a thorough investigation by computer simulation in order to understand self-assembly processes in BDMs.
A method to determine the flexural rigidity of the main dipole for the Large Hadron Collider

The Large Hadron Collider (LHC) superconducting dipole cold mass is a cylindrical structure 15 m long, made of a shrinking cylinder which contains iron laminations and collared coils. This structure, weighing about 28 tons, is horizontally bent by 5 mrad. Its shape should be preserved from the assembly phase to the operational condition at cryogenic temperature. Hence, an accurate comprehension of the mechanical behavior of the cold mass is required. In particular, the flexural rigidity in both horizontal and vertical directions represents one of the foremost properties. To determine the flexural rigidity, deformations of the cold mass induced by the self weight have been measured and compared with the predictions of an analytical structural model. Particular care has been taken in reducing the experimental error by an appropriate fitting procedure.
Phylogenetic Systematics of North American Pseudaelurus (Carnivora: Felidae)

Abstract I review the fossil felid literature, researching the early history of the genus Pseudaelurus in Europe. I examine type Pseudaelurus specimens from Europe, Asia, and North America and emend the generic diagnosis. A large body of new material from the Frick Collection of the American Museum is described and specimens are assigned to one of six species. One species is new and one is transferred from Lynx. New material includes two partial skeletons assigned to two separate species, several skulls, one skull with associated lower jaws and intact basicranium, numerous maxillary and lower jaw specimens, and isolated postcranial items. Cranial, basicranial, and postcranial material of the Frick specimens is compared to that of European taxa as well as to modern felids. A cladistic analysis of 10 taxa and 23 characters produces hypotheses of felid relationships.
Third mandibular molar coronectomy: a way to prevent iatrogenic inferior alveolar nerve injuries—an systematic review

Introduction: In the field of oral and maxillo-facial surgery, the avulsion of third mandibular molar is a very common procedure. However, and although the injury on the alveolar inferior nerve is very rare, the neurological risk must not be underestimated. Indeed, it may lower the patient’s quality of life in a significant way. The coronectomy is a technique that allows us to avoid this risk. It consists in remaining in place the third mandibular molar’s roots. Educational objectives: After a clinical introduction to this surgical technique, the main characteristics of this type of procedure will be presented with the help of an exhaustive literature review. Thus, we will refer to the following subjects: the obvious decrease of neurological risks, the potential pre and post-operating complications, the potential necessity of an endodontic treatment for the residual roots, the becoming of these same roots, and finally the bony and mucosal cicatrization of the operated area. Conclusion: Every oral surgeon should have in mind this technique of coronectomy and master it. Indeed, when the case justifies it, the benefits are numerous for the patient.
The possible protective role of omega 3 on liver of L thyroxine treated male albino rats. Histological and immunhistochemical study

Background: Hyperthyroidism is a condition associated with oxidative damage of liver. Omega-3 fatty acids are effective in various medical conditions due to antioxidant, anti-inflammatory, anti-apoptotic and anti-fibrotic activities.Aim of the work: Here we evaluate the potential effects of omega-3 fatty acids on experimentally induced hyperthyroidism. Materials and methods: Thirty adult male rats were divided equally into 3 groups; Control group (G1) received saline. Hyperthyroid (GII) received L-thyroxine group 0. 1μg/g/day intraperitoneal for 6 weeks. L-thyroxine+Omega-3 group (GIII) received L-thyoxine as previous group then 12% of eicosapentaenoic acid (EPA), and 18% of docosahexaenoic acid (DHA) for 4 weeks (from 3rd to 6th weeks). Blood samples were taken for detection of liver enzymes, serum T3 and TSH. Liver samples were taken for light and electron microscopic examination. Immunohistochemical staining of CD68, Caspase 3 and proliferating cell nuclear antigen (PCNA) were done.Results: L-thyroxine over dose decreased TSH, increased serum T3 and liver enzymes (ALT &AST). Also, it induced patches of cytoplasmic vacuolation, dense nuclei, vascular congestion and significant increase of collagen fibers. Electron microscopic changes revealed rarified cytoplasm and mitochondria with destructed cristae in most hepatocytes, . Significant increase of caspase3 and CD68 immunoexpression and significant decrease of (PCNA) immunoexpression were noticed. Concomitant treatment with omega 3 showed decreased liver enzymes and T3. Improvement of most morphological alterations in the hepatocytes was observed. Significant decrease of collagen fibers, caspase 3 and CD68 immunoexpression was observed and significant increase of PCNA immunoexpression.Conclusion: Combined treatment with omega 3 ameliorated most of L. thyroxine induced liver changes and serological parameters.
Residential Electricity Pricing in China

This article evaluates the new residential pricing system for electricity in China by examining price and income elasticity of demand by household type. We used prereform annual panel data for 29 provinces from 1998 to 2011, applying feasible generalized least squares models. The price and income elasticities for household sectors are -0.412, and 1.476 at the national level, -0.300 and 1.550 in urban areas, and -0.522 and 1.093 in rural areas. With regional effects, the price and income elasticities are -0.146 and 1.286 for urban households in coastal provinces and -0.772 and 1.259 for urban households in inland provinces. The empirical results reveal that there is important heterogeneity in the responsiveness to electricity price changes by household income level and location.
Development of citrus fruit fly control strategies for small-holders in Nigeria

Development of citrus fruit fly control strategies for small-holders in Nigeria. Abstract -- Introduction. Damage of citrus fruits by the Mediterranean fruit fly Ceratitis capi- tata Weid. results in economic losses in Nigeria. The majority of the citrus producers are small- holders who are yet to adopt standard citrus production practices. A trial was therefore esta- blished in a savannah zone of Nigeria with a Southern Guinea agroecology to evaluate simple fruit fly control practices. Materials and methods. The efficacy of combining cultural practices such as removal of dropped fruits, changes of harvest period, and three applications of dimethoate/cypermethrine mixture in controlling fruit fly damage was tested on sweet orange Citrus sinensis (L.) Osbeck var. Valencia Late in 2000 and 2001. Results. Fruits attacked by C. capitata increased with fruit maturity and were positively correlated with the number of drop- ped fruits. Insecticide applications and removal of dropped fruits significantly reduced the num- ber of fruits attacked by the fruit flies. Similarly, early harvesting at 50% fruit ripening significantly (P < 0.05) reduced the number of fruits attacked by the fruit flies when compared with the late harvesting at 90% ripening. The interactive effects of insecticide applications and the period of harvest significantly (P < 0.05) reduced attacks on fruits. Discussions. Judicious use of insec- ticides, periods of harvest and removal of fallen fruits reduce fruit fly damage. Late harvest and non-removal of fallen fruits constitute fruit fly reservoirs for the re-infestation of other clean fruits. Since the tested control methods were simple, they can be adopted by small-holders for the con- trol of fruit flies.
