Liquidity and anomalies: study on stock market liquidity and its affect on momentum and value investment returns.

Purpose of the study This study focuses on the links between stock market liquidity and two of the most studied stock market anomalies: momentum effect and value effect. The aim is to increase knowledge from this area using daily stock market data and to confirm previous results often made using monthly stock market data. Data There are two data sets used in this study. The first part is the daily NYSE stock market data obtained from the CRSP database. The second part is the daily Fama French three factors data downloaded from Kenneth French’s webpage. The collected data is used to build nine different investment portfolios and six different liquidity factors. Results First, the findings show no positive alphas for momentum or value investment strategies during the post 2008 financial crisis period. Second, there is a negative relationship between liquidity shocks and value investment returns, and positive relationship between liquidity shocks and momentum investment returns. Third, the unexpected liquidity shocks, rather than the expected changes in stock market liquidity, forecast momentum and value investment returns. And finally, the positive liquidity shocks have stronger effects than the negative shocks, both in statistical significance and in magnitude, when explaining future momentum and value investment returns.
Testing self-regulation interventions to increase walking using factorial randomized N-of-1 trials.

OBJECTIVE To investigate the suitability of N-of-1 randomized controlled trials (RCTs) as a means of testing the effectiveness of behavior change techniques based on self-regulation theory (goal setting and self-monitoring) for promoting walking in healthy adult volunteers. METHOD A series of N-of-1 RCTs in 10 normal and overweight adults ages 19-67 (M = 36.9 years). We randomly allocated 60 days within each individual to text message-prompted daily goal-setting and/or self-monitoring interventions in accordance with a 2 (step-count goal prompt vs. alternative goal prompt) × 2 (self-monitoring: open vs. blinded Omron-HJ-113-E pedometer) factorial design. Aggregated data were analyzed using random intercept multilevel models. Single cases were analyzed individually. The primary outcome was daily pedometer step counts over 60 days. RESULTS Single-case analyses showed that 4 participants significantly increased walking: 2 on self-monitoring days and 2 on goal-setting days, compared with control days. Six participants did not benefit from the interventions. In aggregated analyses, mean step counts were higher on goal-setting days (8,499.9 vs. 7,956.3) and on self-monitoring days (8,630.3 vs. 7,825.9). Multilevel analyses showed a significant effect of the self-monitoring condition (p = .01), the goal-setting condition approached significance (p = .08), and there was a small linear increase in walking over time (p = .03). CONCLUSION N-of-1 randomized trials are a suitable means to test behavioral interventions in individual participants.
Trends and scenarios of ground-level ozone concentrations in Finland

This paper presents an overview of the changes in ground-level ozone and vegetation exposure occurring in Finland, both as observed in the recent decade, and as estimated for the period 1900 to 2100. A trend analysis of ozone and total nitrate concentrations is carried out for the 1989-2001 period. Future and past concentrations are modelled based on chemistry-transport model simulations, the SRES (Special Report on Emissions Scenarios) scenarios of the Intergovernmental Panel on Climate Change and emission inventories. Measured summertime ozone shows no decreasing trend despite reported precursor emission reductions. In central Finland, AOT40 (accumulated exposure over a threshold of 40 ppb) over April-September is presently about 6300 ppb h and is estimated to decrease by 570 ppb h as a result of the agreed European emissions reductions by 2010. A similar but opposite change results from the enhanced biogenic emissions of volatile organic compounds due to increased temperatures by 2050. According to the SRES scenarios, the tropospheric background concentrations will increase considerably until about 2050. After this, exposures begin to decline in those scenarios which emphasise new technologies and environmental aspects (8100 ppb h by 2050 in the B1 scenario), but increase monotonically in the A scenarios driven by economic growth.
High-temperature thermopower in La2/3Ca1/3MnO3 films: Evidence for polaronic transport.

Thermoelectric power, electrical resistivity, and magnetization experiments, performed in the paramagnetic phase of La{sub 2/3}Ca{sub 1/3}MnO{sub 3}, provide evidence for polaron-dominated conduction in colossal magnetoresistance materials. At high temperatures, a large, nearly-field-independent difference between the activation energies for resistivity {rho} and thermopower {ital S}, a characteristic of Holstein polarons, is observed, and ln{rho} ceases to scale with the magnetization. On approaching {ital T}{sub {ital c}}, both energies become field dependent, indicating that the polarons are magnetically polarized. Below {ital T}{sub {ital c}}, the thermopower follows a law {ital S}({ital H}){approximately}1/{rho}({ital H}) as in nonsaturated ferromagnetic metals. {copyright} {ital 1996 The American Physical Society. }

Prenatal diagnosis of 45,X and 45,X mosaicism: the need for thorough cytogenetic and clinical evaluations

Mosaicism involving a 45,X cell line is relatively common in prenatal diagnosis. In prenatally diagnosed cases, the prognosis of non‐mosaic 45,X and 45,X/46,XY mosaicism are different. Therefore, accurate identification of a cell line containing Y chromosome is critical for genetic counseling and postnatal management.
Corporate Bond Dealers' Inventory Risk and FOMC

Macroeconomic announcements increase trading activity, with potential consequences for liquidity. This paper studies the effect of FOMC announcements on the US corporate bond market liquidity. The releases do not seem to create adverse selection. We obtain the probability distribution of monetary policy outcomes from 30 day Fed funds Futures. Despite the low toxicity of the order flow, dealers increase the price for liquidity provision in the presence of monetary policy uncertainty and unexpected Fed rate changes. Trading costs decomposition reveals that inventory risk aversion drives the dealers' behaviour. We conclude that a dealership market falls short around macroeconomic announcements, even when adverse selection may be absent.
Improving Conception Rate in Lactating Dairy Cows by Using Modified Ovsynch Protocol during Summer

The aim of this study was to test two different timed artificial insemination (AI) protocols in order to improve the percentage of pregnant cows per AI in lactating dairy cows during the summer. Cows (n=140) were randomly divided into two groups; cows in the OVS group (n=75) received the Ovsynch protocol (GnRH–7d–PGF2α–2d–GnRH–16h–AI), and cows in the MOVS group (n=65) received the Ovsynch protocol with exogenous progesterone (P4) which administrated between GnRH and PGF2α. In addition, GnRH was injected 7 d after AI in the MOVS group (GnRH–P4–7d –PGF2α–2d–GnRH–16h–AI–7d–GnRH). Response to the second GnRH treatment of Ovsynch (GnRH-2) was greater (P<0.03) in the MOVS (98.5%) than the OVS (89.3%) group. Although P/AI at 31 d was numerically greater in the MOVS (46.2%, 30/65) than the OVS (37.3%, 28/75) group, this difference was statistically insignificant. Thus, because of the greater response to GnRH-2 and P/AI in MOVS compared with the OVS group, the MOVS protocol can be used to improve P/AI in lactating dairy cows during the summer, but further studies are needed to be evaluated the effects of the MOVS protocol on P/AI during the summer.
Localization of Janusin mRNA in the Central Nervous System of the Developing and Adult Mouse

Janusin (formerly termed J1‐160/180) is an oligodendrocyte‐derived extracellular matrix molecule which is restricted to the central nervous system and which is expressed late during development (Pesheva et al., J. Cell Biol., 1765 – 1778, 1989). To gain insights into the molecule's morphogenetic functions and to identify its cellular source in vivo, we have studied the localization of janusin messenger RNA in the optic nerve, retina and spinal cord and the expression of janusin protein in the spinal cord of developing and adult mice. Moreover, we have analysed optic nerve cell cultures and retinal cell suspensions in double‐labelling experiments using a janusin‐specific anti‐sense complementary RNA probe and cell type‐specific antibodies to identify the cell types containing janusin transcripts. In developing animals, oligodendrocytes were strongly labelled with the janusin anti‐sense cRNA probe during the period of myelination. The number of labelled cells and intensity of the hybridization signal decreased significantly with increasing age. Interestingly, expression of janusin was not confined to oligodendrocytes. Some neuronal cell types and type‐2 astrocytes present in optic nerve cell cultures also contained janusin transcripts. In contrast to oligodendrocytes, the number and labelling intensity of neurons containing janusin transcripts remained constant during postnatal development and into adulthood. Expression of janusin protein in the spinal cord was developmentally regulated, with a peak of expression in 2‐or 3‐week‐old animals. The molecule was visible in the white and grey matter. In myelinated regions, it was associated with myelinated fibres and accumulated at nodes of Ranvier. These observations suggest that janusin may be of functional relevance for myelination.
Aerodynamic characteristics of a square section cylinder: Effect of corner arc

Numerical simulation results on the effect of corner arc (radius ‘r’) on the aerodynamic characteristics of a square section cylinder (side dimension, B) are presented in this paper. Simulation was carried out by using the commercial code ANSYS-Fluent at a Reynolds value of 2100 (based on B). Results show that as r/B ratio (CR) increases, coefficients of drag and lift decrease till CR = 0.2 further to which they increase. Whereas, Strouhal number registers an opposite trend as that of drag and lift. It is inferred that the value of the percentage of drag reduction is around 21.49% for corner ratio 0.2 configuration, which also has the highest Strouhal number = 0.17 and it proves to be the most effective configuration out of all the configurations attempted in this study.
Combination Estrogen–Progestin Contraceptives and Body Weight: Systematic Review of Randomized Controlled Trials

OBJECTIVE: Many women and clinicians believe that combination estrogen–progestin contraceptive use can lead to weight gain. This concern can deter women from starting hormonal contraception or lead to premature quitting. This review evaluated the association between combination contraceptive use and change in body weight. DATA SOURCES: The computerized databases CENTRAL, MEDLINE, EMBASE, Popline, and LILACS (from their inception to 2002) were used to conduct this review. Known investigators and manufacturers were contacted for information about other trials not discovered in the database search. METHODS OF STUDY SELECTION: All English-language, randomized controlled trials measuring weight change that were at least 3 treatment cycles in duration and that compared a combination contraceptive to a placebo or to a combination contraceptive that differed in drug, dosage, regimen, or study length were eligible for inclusion. Of the 570 reports of randomized controlled trials of eligible interventions that were identified, 42 trials were included in the systematic review. TABULATION, INTEGRATION, AND RESULTS: Two reviewers independently abstracted data from the eligible trials using a standard form. Depending on the data available, the weighted mean difference using a fixed effect model with 95% confidence intervals was calculated for the mean change in weight between baseline and posttreatment measurements or the Peto odds ratio with 95% confidence intervals was calculated by using the proportion of women who gained or lost more than a specified amount of weight. The 3 placebo-controlled, randomized trials did not find evidence supporting a causal association between combination oral contraceptives or a combination skin patch and weight gain. Most comparisons from the 40 trials that compared 2 or more combination contraceptives showed no substantial difference in weight. In addition, discontinuation of combination contraceptives because of weight gain did not differ between groups when this factor was studied. CONCLUSION: Available evidence is insufficient to determine the effect of combination contraceptives on weight, but no large effect is evident.
GENDER EQUALITY AND THE GENDER GAP IN MATHEMATICS

Summary A gender gap has been found in mathematics (boys outperform girls) that has prevailed across countries for many decades. Whether this gap results from nature or nurture has been hotly debated. Using the evidence of PISA 2003 and the gender equality index of 2003, some researchers have argued that an improvement in gender equality reduces the gender gap in mathematics. This study used five waves of country-level PISA data and, controlling for country fixed effects, found no evidence to support this argument. Furthermore, individual data for PISA 2012 and the multilevel data model were used. The conclusion drawn also does not support the argument. In fact, the relationship between gender equality and the gender gap in mathematics vanished after PISA 2003.
Association of genetic risk severity with ADHD clinical characteristics

This study sought to examine the association between the cumulative risk severity conferred by the total number of attention‐deficit/hyperactivity disorder (ADHD) risk alleles of the DAT1 3′UTR variable number tandem repeat (VNTR), DRD4 Exon 3 VNTR, and 5‐HTTLPR with ADHD characteristics, clinical correlates, and functional outcomes in a pediatric sample. Participants were derived from case–control family studies of boys and girls diagnosed with ADHD, a genetic linkage study of families with children with ADHD, and a family genetic study of pediatric bipolar disorder. Caucasian children 18 and younger with and without ADHD and with available genetic data were included in this analysis (N = 591). The association of genetic risk severity with sociodemographic, clinical characteristics, neuropsychological, emotional, and behavioral correlates was examined in the entire sample, in the sample with ADHD, and in the sample without ADHD, respectively. Greater genetic risk severity was significantly associated with the presence of disruptive behavior disorders in the entire sample and oppositional defiant disorder in participants with ADHD. Greater genetic risk severity was also associated with the absence of anxiety disorders, specifically with the absence of agoraphobia in the context of ADHD. Additionally, one ADHD symptom was significantly associated with greater genetic risk severity. Genetic risk severity is significantly associated with ADHD clinical characteristics and co‐morbid disorders, and the nature of these associations may vary on the type (externalizing vs. internalizing) of the disorder. © 2013 Wiley Periodicals, Inc.
Meta-analyses of Post-acquisition Performance: Indications of Unidentified Moderators

Empirical research has not consistently identified antecedents for predicting post‐acquisition performance. We employ meta‐analytic techniques to empirically assess the impact of the most commonly researched antecedent variables on post‐acquisition performance. We find robust results indicating that, on average and across the most commonly studied variables, acquiring firms' performance does not positively change as a function of their acquisition activity, and is negatively affected to a modest extent. More importantly, our results indicate that unidentified variables may explain significant variance in post‐acquisition performance, suggesting the need for additional theory development and changes to M&A research methods.

Role of hole fluence in gate oxide breakdown

A simple model which links the primary hole and Fowler-Nordheim (FN) electron injections to oxide breakdown is established and the calculation based on this model is in good agreement with our experiments. When the sum of the active trap density D/sup pri/ due to primary hole injection and the active trap density D/sup n/ due to FN electron injection reaches a critical value D/sub cri/, the oxide breaks down. The hole is two orders of magnitude more effective than FN electron in causing breakdown. These new findings are imperative in predicting oxide reliability and device lifetime.
Accuracy of DFT-based synchrophasor estimators at off-nominal frequencies

The accuracy of synchrophasor estimators is a well-known critical issue in systems for smart grid monitoring and control. This paper presents an in-depth analysis of the effect of off-nominal frequency deviations on single-cycle and multi-cycle DFT-based synchrophasor estimators. Unlike other qualitative or simulation-based results available in the literature, this work provides some accurate and easy-to-use expressions that can be used to keep the total vector error within given target uncertainty boundaries.
Distribution of muscarinic receptor subtype M3 in melanomas and their metastases

Background: Muscarinic acetylcholine receptors (mR) are involved in the regulation of cancer cell motility and cancer progression. mR have been shown in melanoma cell lines and cryostat sections of melanomas. To substantiate the experimental data, here the correlation of mR‐expression with invasive growth was studied on the cellular level by comparison with HMB‐45 immunoreactivity.
QUALITY OF LIFE IN PARKINSON ’ S DISEASE PATIENTS IN TIKUR ANBESSA SPECIALIZED HOSPITAL AND ZEWDITU MEMORIAL HOSPITAL , ADDIS ABABA , ETHIOPIA

Background: Recently, studies have suggested both motor and non-motor symptoms (NMS) have an impact on the health-related quality of life (HrQoL) among patients with Parkinson’s Disease (PD). However, little is known about health-related quality of life (HrQoL) among people with PD in Ethiopia. Objective: To determine the health related quality of life in PD patients seen in the outpatient clinics of Tikur Anbessa Specialized Hospital (TASH) and Zewditu Memorial Hospital, (ZMH) Addis Ababa, Ethiopia. Methods: All PD patients attending neurology follow up clinic aged 18 years and above at TASH AND ZMH from October 2014 to January 2015 were included in the study. Health-related quality of life was evaluated using PDQ -39 which is a 39 item questionnaire. Motor symptoms severity was evaluated with UPDRS: part 3, which assesses severity of motor signs using a scale 0 to 4. Hoen and Yahr stage was used to assess severity. Multiple linear regression analysis was used to predict demographic and clinical factors for HrQoL in PD patients. Results: A total of 128 PD patients participated in the study. The mean age of the participants was 59.5 years. Mean duration of illness was 6 years. The mean PDQ 39 Summery Index (SI) was 40.5 (95% CI: 37-44). The PDQ 39 domains with higher scores were Activity of Daily living (ADL), emotional wellbeing, body discomfort and cognition; profiles such as social support, communication, stigma and mobility showed lowest scores (good QoL). The demographic and clinical factors that predicted HrQoL were education, (β =0.053, p<0.01), duration of disease (β=0.152, p<0.001), UPDRS 3 unified PD rating scale total score (β=0.083, p< 0.001), H&Y score (β=0.140, p< 0.001), depression (β=0.339, p< 0.001 and anxiety (β=0.423, p< 0.000). Conclusion: HrQoL worsens with increased depression, anxiety, and disease severity. Therefore it is prudent to recognize and assess depressive symptoms and disease severity so that symptoms may be managed enabling patients to enjoy a better quality of life.
Polyphenolic compounds and in vitro antimicrobial and antioxidant activity of aqueous extracts from leaves of some Cirsium species

Crude aqueous extracts from leaves of Cirsium arvense, C. oleraceum, C. palustre, C. rivulare and C. vulgare were investigated. The content of tannins in mentioned sources, determined by the weight method with hide powder, varied between 1 and 7.63%. Total phenolic content, analysed by using Folin–Ciocalteau's method, ranged between 54 and 96 mg g−1, was expressed as milligrams of gallic acid per gram of dry extract. Phenolic acids were identified by HPLC method. Antimicrobial activity of those extracts was examined. Cirsium palustre extract was the most active against investigated microorganisms. It was observed that the content of small-molecular phenolic compounds had greater influence on the activity of extracts than tannins. The total antioxidant activity indicated by radical cation 2,2′-azini-di-(3-ethylbenzthiazoline sulphonate) ABTS•+, expressed as total antioxidant status (TAS) ranged from 2.31 to 2.78 mM L−1.
Women Exposures and Lung Cancer among Chinese Nonsmoking Dose-Response Relationship between Cooking Fumes

The high incidence of lung cancer among Chinese females, despite a low smoking prevalence, remains poorly explained. Cooking fume exposure during frying could be an important risk factor. We carried out a population-based case-control study in Hong Kong. Cases were Chinese female nonsmokers with newly diagnosed primary lung cancer. Controls were female nonsmokers randomly sampled from the community, frequency matched by age groups. Face-to-face interviews were conducted using a standardized questionnaire. The ‘‘total cooking dish-years,’’ categorized by increments of 50, was used as a surrogate of cooking fumes exposure. Multiple unconditional logistic regression was used to estimate the odds ratios (OR) for different levels of exposure after adjusting for various potential confounding factors. We interviewed 200 cases and 285 controls. The ORs of lung cancer across increasing levels of cooking dish-years were 1, 1.17, 1.92, 2.26, and 6.15. After adjusting for age and other potential confounding factors, the increasing trend of ORs with increasing exposure categories became clearer, being 1, 1.31, 4.12, 4.68, and 34. The OR of lung cancer was highest for deep-frying (2.56 per 10 dish-years) followed by that of frying (1.47), and stir-frying had the lowest OR (1.12) among the three methods. Cumulative exposure to cooking by means of any form of frying could increase the risk of lung cancer in Hong Kong nonsmoking women. Practical means to reduce exposures to cooking fumes should be given top priority in future research. (Cancer Res 2006; 66(9): 4961-7)
