Value or Growth Strategy? Empirical Evidence in Brazil

This article aimed at verifying the existence of value versus growth and at identifying the variables that best explain their impact on Brazilian stock profits. To this end, we tested book-to-market, price-earnings and price-to-cash flow variables. Two methodological approaches were employed: portfolio analysis, in which portfolios were formed according to each variable of interest and regression analysis with panel data, based on individual assets. The sample was made up of companies with shares traded in BM&FBOVESPA during the 1995-2008 period. According to results found, growth stocks presented higher profits than value stocks. Thus, we may conclude that the well-documented value versus growth is not valid in Brazil, since empirical evidence supported growth strategies. Due to the long research period, results may signal prevalence of growth strategy in the long term. Furthermore, the high volatility of emerging countries’ capital markets was emphasized, as pointed out by Fama and French (1998). Moreover, to establish investment strategies that allow for greater profits, it was found that the variable that best identifies growth stocks is the book-to-market ratio.
The Management of Modern Salt Business as a Community Economic Improvement on Remote Islands in East Nusa Tenggara, Indonesia

way contains NaCl 95% - 97% so that it is not only for consumption needs but also suitable for industrial needs. The salt industry with geomembrane technique is one of the modern salt industries which at this time has been widely developed. The production process of salt cultivation using geomembrane techniques is faster, which is around 10-14 days with production increasing to more than 200%, and the product selling price is much higher (Effendi, Zainuri, and Hafiluddin, 2012; Iswidodo and Ciptomulyono, 2013). The salt industry with geomembrane techniques has also been implemented in the NTT region. Because starting this business required a lot of capital, two local governments in NTT initiated the business by involving local communities. Supposedly, the semi-arid conditions in NTT would greatly support this modern salt industry to be able to produce optimally. However, in fact, not all businesses run smoothly. Some of the salt industries with geomembrane techniques have not developed well, although there are also those whose business is progressing rapidly. Abstract: The modern salt business is an alternative to the community's economic business in remote island areas. However, this business requires large investment capital which is impossible for local people to do, so it needs support from the government and the private sector. This study aims to obtain a model of management for the modern salt business by involving local communities. The results showed that there are three scenarios of modern salt industry management models with the involvement of local communities where the two models have gone through the review, evaluation and adaptation stages so it is expected that there will be perfection in its implementation. Meanwhile, one other model has never been implemented so requires initiation from the local government and the private sector to start piloting this scenario.
The thick frame of a weak twin building

We prove the following extension to twin buildings of a result for spherical buildings which appears in [11] : to every weak twin building ∆, is canonically associated a thick twin building ∆ whose Weyl group W (∆) can be considered as a reflection subgroup of the Weyl group W (∆) of ∆ ; conversely, it is possible to recover ∆ from the thick twin building ∆ and from the inclusion W (∆) → W (∆).
Green Supply Chain Management: Drivers and Impact on Performance

Green supply chain management has been an important organizational strategy to reduce environmental risks and improve financial performance. This paper presents an empirical study of the drivers of green supply chain management (GSCM) practices and the environmental and economic performance of GSCM implementation in Chinese firms. This study confirms that (1) both internal and external drivers play a significant role in the implementation of GSCM practices; (2) green purchase and investment recovery have a significant impact on firms’ environmental and economic performance; (3) with the improvement of the firms’ environmental performance, their economic performance will improve.
Gamma-Ray Bursts Induced by Turbulent Reconnection

We revisit the Internal-Collision-induced MAgnetic Reconnection and Turbulence model of gamma-ray bursts (GRBs) in view of the advances made in understanding of both relativistic magnetic turbulence and relativistic turbulent magnetic reconnection. We identify the kink instability as the most natural way of changing the magnetic configuration to release the magnetic free energy through magnetic reconnection, as well as driving turbulence that enables fast turbulent reconnection. We show that this double role of the kink instability is important for explaining the prompt emission of GRBs. Our study confirms the critical role that turbulence plays in boosting reconnection efficiency in GRBs and suggests that the GRB phenomena can be modeled in the magnetohydrodynamics approximation. That is, the modeling is not constrained by reproducing the detailed microphysical properties of relativistic magnetized plasmas.
Robust estimation of a multi-layered motion representation

In order to recover an accurate representation of a scene containing multiple moving objects, one must use estimation methods that can recover both model parameters and segmentation at the same time. Traditional approaches to this problem rely on an edge-based discontinuity model, and have problems with transparent phenomena. The authors introduce a layered model of scene segmentation based on explicitly representing the support of a homogeneous region. The model employs parallel robust estimation techniques, and uses a minimal-covering optimization to estimate the number of objects in the scene. Using a simple direct motion model of translating objects, they successfully segment real image sequences containing multiple motions. <<ETX>>
Intercellular Connections in the Heart: The Intercalated Disc

Proper cardiac function requires the synchronous mechanical and electrical activity of individual cardiomyocytes to ensure the coordinated excitation and contractile performance of the heart, as an organ. The intercalated disc (ID), a unique membrane structure forming at the edges of mammalian cardiomyocytes (Li and Radice, 2010), fulfills this role by allowing the transmission of mechanical and electrical activity between neighboring cells; (reviewed in Delmar and McKenna, 2010; Noorman et al., 2009).
Social Discrimination in the Corporate Elite

This study examines social discrimination in the attributions that top executives make about the performance of other firms with minority CEOs in their communications with journalists. Drawing from the literatures on intergroup relations and status competition, our theory suggests how out-group biases and negative forms of envy toward higher-status minority CEOs may increase the propensity for white male CEOs to make negative or internal attributions for the low performance of the minority CEOs’ firms. We also examine how CEOs’ internal attributions in conversations with journalists increase the tendency for those journalists to attribute performance to internal causes in reporting on the minority CEOs’ firms. We consider how the gender and race of journalists could moderate the influence of CEOs’ performance attributions on journalists’ reports, such that female or racial minority journalists would be less easily persuaded by white male CEOs’ internal attributions for the low performance of firms with female or racial minority CEOs, and thus less prone to issuing negative statements about the CEOs’ leadership. Empirical analyses based on original survey data from a large sample of CEOs and journalists provided strong support for our hypotheses. We discuss implications of the findings for theory and research on social discrimination in the corporate elite and social psychological determinants of corporate leader reputation.
Exponential time algorithms for graph coloring

Let [k] denote the set {1, . , k}. A k-labeling of vertices of a graph G(V,E) is a function V −→ [k]. Given a k-labeling, an edge is monochromatic if both its endpoints are assigned the same label. A k-labeling is a k-coloring if no edge is monochromatic. The chromatic number of a graph is the minimum k for which a k-coloring exists. Observe that in a k-coloring, every color class is an independent set (no two vertices induce an edge of G), and hence a k-coloring is a partitioning of V into k independent sets, and also a covering V by k independent sets. Deciding whether a graph has a k-coloring for k ≥ 3 is NP-hard. Hence one would not expect to find a polynomial time algorithm for it. The trivial algorithm will try all possible k-labeling, and would take time kn. The purpose of this write-up is to show that despite NP-hardness, there is plenty of room for designing algorithms that are substantially more efficient than the trivial algorithm. Throughout we assume that all graphs are connected, since otherwise each connected component can be colored separately. In analyzing running times of algorithms, we shall omit factors that are polynomial in n and shall only be concerned with the exponential terms. For example, a running time of n32n will be denoted as O∗(2n).
Character-to-Word Attention for Word Segmentation

Although limited eﬀort has been devoted to exploring neural models in Japanese word segmentation, much eﬀort has been actively applied to Chinese word segmentation because of the ability to minimize eﬀort in feature engineering. In this work, we propose a character-based neural model that makes joint use of word information useful for disambiguating word boundaries. For each character in a sentence, our model uses an attention mechanism to estimate the importance of multiple candidate words that contain the character. Experimental results show that learning attention to proper words leads to accurate segmentations and that our model achieves better performance than existing statistical and neural models on both in-domain and cross-domain Japanese word segmentation datasets.
Real-World Administration of Once-Daily MeltDose® Prolonged-Release Tacrolimus (LCPT) Allows for Dose Reduction of Tacrolimus and Stabilizes Graft Function Following Liver Transplantation

The calcineurin inhibitor tacrolimus is included in most immunosuppressive protocols after liver transplantation. This retrospective, observational 24-month study investigated the tolerability of once-daily MeltDose® prolonged-release tacrolimus (LCPT) after switching from twice-daily immediate-release tacrolimus (IR-Tac) in a real-world cohort of 150 patients with previous liver transplantation. No graft rejection or new safety signals were observed. Only 7.3% of patients discontinued LCPT due to side effects. In the overall patient population, median liver transaminases, total cholesterol, triglycerides, glucose, and HbA1c remained constant after switching to LCPT. Total cholesterol significantly decreased (p ≤ 0.002) in patients with initially elevated levels (>200 mg/dL). A total of 71.8% of 96 patients maintained a glomerular filtration rate > 60 mL/min/1.73 m2 throughout the study, while 44.7% of patients were classified as fast metabolizers and 55.3% as slow metabolizers. Median daily tacrolimus dose could be reduced by 50% in fast metabolizers and by 30% in slow metabolizers, while trough levels were maintained in the target range (4–6 ng/mL). In conclusion, our observational study confirmed previous evidence of good overall tolerability and a favorable outcome for the patients after switching from IR-Tac to LCPT after liver transplantation.
Asthma, severe acute respiratory syndrome coronavirus-2 and coronavirus disease 2019.

PURPOSE OF REVIEW In December 2019, a novel respiratory illness caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was first described and named coronavirus disease 2019 (COVID-19). Although the knowledge base surrounding COVID-19 and SARS-CoV-2 has grown rapidly, significant gaps in our knowledge remain and inaccurate information continues to circulate. This review will discuss the interaction between asthma and COVID-19 to provide a comprehensive understanding based on the currently available published data. RECENT FINDINGS Non-SARS human coronaviruses (HCoVs) are a significant cause of asthma exacerbations, but SARS-CoV-2 does not appear to exacerbate asthma. Data thus far strongly suggest that patients with asthma are at no increased risk of infection with SARS-CoV-2 or more severe disease if infected with COVID-19. Although the data are extremely limited on inhaled corticosteroids and biologic medications, there remain no data suggesting that these therapeutics positively or negatively impact the severity or outcome of COVID-19. SUMMARY Data are rapidly evolving regarding COVID-19 and asthma. At this time, asthma does not appear to positively or negatively affect outcomes of COVID-19; however, it is imperative that practitioners keep abreast of the changing literature as we await a vaccine and control of this pandemic.
Scaling properties of rainfall and their impact on rain rate estimation from weather radar

In this paper we consider an alternative approach based on the measurements of a Dual-Beam Spectropluviometer (DBS), in Palaiseau (France). This instrument, described elsewhere (Verrier et al., 2011), provides measurements of diameter, fall speed and time of arrival of raindrops. The latter data can therefore be used to compute simultaneous rain rates and reflectivity factors that can be compared without instrument-to-instrument discrepancy.
The Quantitative View of Myerson Regularity

In mechanism design, Myerson regularity is often too weak for a quantitative analysis of performance. For instance, ratios between revenue and welfare, or sales probabilities may vanish at the boundary of Myerson regularity. This paper therefore explores the quantitative version of Myerson regularity, which we call λ-regularity. It measures how Myerson regular a distribution is. In doing so, we unify separate literatures in economics, computer science, applied mathematics and statistics. The concept has appeared before, e.g., under the names of ρ-concavity and α-strong-regularity. We provide many new results for quantitative auction and mechanism design.
Deposition From a Sour Heavy Oil Under Incipient Coking Conditions: Effect of Surface Materials and Temperature

Fouling in vacuum tower furnaces has been a great challenge in refineries. At the elevated temperatures of these units, coke deposition is common. For sour oils, iron sulfide also accumulates in the carbonaceous deposits, arising from iron dissolved in the feed or from corrosion of metal surfaces. In this work, the combined fouling mechanism is investigated using an atmospheric tower bottom stream which contains 4.1 wt. % sulfur, and 744 wppm dissolved iron. Isothermal deposition experiments running for 6–24 hours have been carried out on a rotating cylinder in a 600-ml batch reactor, at bulk temperatures of 380–410°C and cylinder rotation speeds of 300 rpm. A ring of either carbon steel or alloy is mounted in the cylinder to serve as a corroding or noncorroding surface, respectively. After each experiment, the thickness and weight of deposit on the metal ring are determined. The compositions of deposit are characterized. The rates of deposit formation on the ring and the deposit composition are reported as functions of temperature for a number of metal surfaces. Radial profiles of deposit composition are presented. The probable fouling mechanisms are discussed, based on the present results.
Shiftwork and Light at Night Negatively Impact Molecular and Endocrine Timekeeping in the Female Reproductive Axis in Humans and Rodents

Shiftwork, including work that takes place at night (nightshift) and/or rotates between day and nightshifts, plays an important role in our society, but is associated with decreased health, including reproductive dysfunction. One key factor in shiftwork, exposure to light at night, has been identified as a likely contributor to the underlying health risks associated with shiftwork. Light at night disrupts the behavioral and molecular circadian timekeeping system, which is important for coordinated timing of physiological processes, causing mistimed hormone release and impaired physiological functions. This review focuses on the impact of shiftwork on reproductive function and pregnancy in women and laboratory rodents and potential underlying molecular mechanisms. We summarize the negative impact of shiftwork on female fertility and compare these findings to studies in rodent models of light shifts. Light-shift rodent models recapitulate several aspects of reproductive dysfunction found in shift workers, and their comparison with human studies can enable a deeper understanding of physiological and hormonal responses to light shifts and the underlying molecular mechanisms that may lead to reproductive disruption in human shift workers. The contributions of human and rodent studies are essential to identify the origins of impaired fertility in women employed in shiftwork.
Financial Market Integration and Economic Growth in the EU

The diversity in the current degree of financial development across the EU can be a great opportunity at a time where this area is poised to become increasingly financially integrated. Integration should accelerate the development of the most backward financial markets, and allow companies from these countries to access more sophisticated credit and security markets. In line with a large recent literature, it is reasonable to expect that financial integration will have a "growth dividend" in Europe. This paper attempts to quantify this growth dividend, using both industry and firm-level data to estimate the empirical relationship between financial market development and growth, and to gauge how it will distribute itself across countries and sectors.
Diet Quality of Elite Australian Athletes Evaluated Using the Athlete Diet Index

While athletes’ nutrient intakes have been widely reported, few studies have assessed the diet quality of athletes. This is the first study to evaluate the diet quality of athletes using the purpose-built Athlete Diet Index (ADI). A convenience sample of 165 elite athletes from Australian sporting institutions completed the ADI online, with subsequent automated results provided to their respective accredited sports dietitians (ASDs). At the completion of athlete participation, ASDs (n = 12) responded to a range of survey items using a Likert scale (i.e., 1 = strongly agree to 5 = strongly disagree) to determine the suitability of the ADI in practice. Differences in ADI scores for demographics and sport-specific variables were investigated using independent t-tests, analysis of variance (ANOVA) and Bonferroni multiple comparisons. Spearman’s rank correlation was used to assess the association between total scores and demographics. The mean total ADI score was 91.4 ± 12.2 (range 53–117, out of a possible 125). While there was no difference in total scores based on demographics or sport-specific variables; team sport athletes scored higher than individual sport athletes (92.7 vs. 88.5, p < 0.05). Athletes training fewer hours (i.e., 0–11 h/week) scored higher on Dietary Habits sub-scores compared with athletes training more hours (≥12 h/week; p < 0.05), suggesting that athletes who train longer may be at risk of a compromised dietary pattern or less than optimal nutrition practices that support training. Most (75%) ASDs surveyed strongly agreed with the perceived utility of the ADI for screening athletes and identifying areas for nutrition support, confirming its suitability for use in practice.
Improving Rate of Gelatin/Carboxymethylcellulose Dissolving Microneedle for Transdermal Drug Delivery

Gelatin has been widely used as a nature-derived biopolymer material due to its high biocompatibility and abundance. However, multiple fabrication steps for the moulding process may limit its application to microneedle technology as biomedical application. This research focused on physical, chemical, and mechanical characteristics of gelatin-based dissolving microneedle (DMN) by adding in various concentrations of carboxymethylcellulose. Carboxymethylcellulose (CMC) derived from kenaf bast fibre were extracted by alkaline treatment and esterification process, followed by fabrication of DMN with gelatin using centrifuge-casting method. The formulation of G/CMC6 demonstrated the highest mechanical strength of 11.2 N by texture analyzer; hence, G/CMC6 was chosen for further investigate of its intra- and intermolecular bond, amorphous study, and its geometry by Fourier Transform Infrared (FTIR), X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). FTIR showed various chemical interactions involved including hydrogen bonding, dipole-dipole and charge effect. The XRD result shows amorphous peak of gelatin decreased at 2θ = 20 - 21° with the addition of CMC. The height of microneedle arrays also decreased from its micromould by 36.7% due to agglomeration of CMC. Considering the biodegradability and the improvement of gelatinbased DMN mechanical properties by carboxymethylcellulose, the combination of gelatin and CMC is one of great potential for delivering drugs using microneedle.
New Bioactive Peptides Identified from a Tilapia Byproduct Hydrolysate Exerting Effects on DPP-IV Activity and Intestinal Hormones Regulation after Canine Gastrointestinal Simulated Digestion

Like their owners, dogs and cats are more and more affected by overweight and obesity-related problems and interest in functional pet foods is growing sharply. Through numerous studies, fish protein hydrolysates have proved their worth to prevent and manage obesity-related comorbidities like diabetes. In this work, a human in vitro static simulated gastrointestinal digestion model was adapted to the dog which allowed us to demonstrate the promising effects of a tilapia byproduct hydrolysate on the regulation of food intake and glucose metabolism. Promising effects on intestinal hormones secretion and dipeptidyl peptidase IV (DPP-IV) inhibitory activity were evidenced. We identify new bioactive peptides able to stimulate cholecystokinin (CCK) and glucagon-like peptide 1 (GLP-1) secretions, and to inhibit the DPP-IV activity after a transport study through a Caco-2 cell monolayer.
PILOT COGNITIVE FUNCTIONING AND TRAINING OUTCOMES

Abstract : The current study examined the relationship between clinical cognitive functioning tests and U.S. Air Force pilot training outcomes. Three computerized tests were used: the Multidimensional Aptitude Battery, MicroCog, and CogScreen. In addition to the traditional pass/fail training outcome, the quality of passing and reasons for failure were examined. Outcome criteria for training graduates included class rank, academic grades, daily flying grades, and check ride grades. Reasons for failure included flying training deficiency and being ? Dropped on Request. Correlations in samples of between 5,582 and 12,924 trainees across the tests showed small, but important, relationships with training outcomes. All three of the clinical tests performed similarly. There was little evidence that any specific cognitive variable was more important than any other, and the results pointed to general cognitive ability as the main predictor of performance. In terms of the outcome variables, performance for graduates (e.g., class rank) was better predicted than training attrition.
