Published: June 2017

AbstractBackgroundCardiovascular diseases constitute the main death cause worldwide resulting from a combination of genetic and lifestyle factors, and the prevalence among younger individuals has increased. It is important to early identify changes in lipid profile and the influence of genetic variations in specific genes on the individual patterns of lipid profile. Thus, the aim of this study was to verify the relationship of polymorphisms in PPAR-gamma gene (PPARG− rs1801282 − Pro12Ala) and in apolipoprotein E gene (APOE −rs429358 + rs7412, determinants of the APOE2, APOE3, or APOE4 genotypes) with lipid profile of adolescents under cardiovascular risk factors.MethodsThis was a cross-sectional study with 115 adolescents aged 10–19 years, which presented cardiovascular risk factors. The students were evaluated regarding socioeconomic, anthropometric, biochemical, genetic, and dietetic variables. Student’sttest or Mann-Whitney test were applied to the analysis of the genotypes. Multiple linear regression analysis was performed to determine the variables that most influenced the lipid profile.ResultsAdolescents carryingPPARGAla allele showed higher serum triglycerides (p = 0.0423) and very low-density lipoprotein (p = 0.0410) levels when compared to those carrying the wild genotype. For theAPOEpolymorphism, it was observed a trend of higher triglycerides (p = 0.0712) and very low-density lipoprotein (p = 0.0758) levels in the adolescents carrying the E4 allele when compared to those who did not carry this allele.ConclusionThe polymorphismsPPARGrs1801282 andAPOErs429358 + rs7412 seem to be related to the development of lipid profile alterations in adolescents.
Heike Paintings in the Early Edo Period
Authors: Gunji Naoko 
Published: June 2017

Abstract
The Heike monogatari (Tale of the Heike) is a warrior chronicle represented in a variety of formats: not just texts but narration, performing arts, and paintings, among others. This paper explores the elite reception of Heike paintings in the Edo period by connecting it closely to the reception of other formats. Studying the “Chishakuin group”—a canonical group of paintings for elites depicting two battles in the Heike monogatari—and analyzing in particular the pair of screens in the British Museum, I will bring to light some intended functions of a social, political, and ideological nature that the Edo warrior elite expected of these paintings: most centrally, to edify the audience and legitimize the Tokugawa rule. As will be shown, these functions relied closely on the similar ones expected of other formats of the Heike monogatari. In fact, I will argue that Heike paintings, as well as the tale itself, were targeted to and received by elite women, not just men. I will investigate an interesting case of appreciation of Heike picture scrolls in 1632 by Tōfukumon'in, a daughter of the second Tokugawa shogun Hidetada and the imperial consort of Emperor Go-Mizunoo. It will be made clear that political and ideological reasons stemming from her particular background and circumstances were behind Tōfukumon'in's practice of reading the Heike paintings.
More Than Mere Diversion
Authors: Lee De-Nin D. 
Published: June 2017

AbstractWhereas texts on painting by Chinese literati have had a profound impact on art history, women's writings are almost unknown. This article examines poems by the Qing-dynasty poet-painter Luo Qilan (b. 1755), using her as a case study to argue for a literatae tradition in painting. Luo's tihuashi (poems on paintings) and related poems bear witness to vigorous participation in the culture of Chinese painting. Her poems evidence learning from male teachers and female exemplars, adaptation of masculine conventions, and adroit use of poetic and painterly skills to cultivate supporters who disseminated her reputation beyond the Inner Chambers.
Competition-Based Dynamic Pricing in Online Retailing: A Methodology Validated with Field Experiments
Authors: Fisher Marshall , Gallino Santiago , Li Jun 
Published: June 2017

A retailer following a competition-based dynamic-pricing strategy tracks competitors’ price changes and then must answer the following questions: (i) Should we respond? (ii) If so, to whom? (iii) How much of a response? (iv) And on which products? The answers require unbiased measures of price elasticity as well as accurate estimates of competitor significance and the extent to which consumers compare prices across retailers. There are two key challenges to quantify these factors empirically: first, the endogeneity associated with almost any type of observational data, where prices are correlated with demand shocks observable to pricing managers but not to researchers, and second, the absence of competitor sales information, which prevents efficient estimation of a full consumer-choice model. We address the first issue by conducting a field experiment with randomized prices. We resolve the second issue by exploiting the retailer’s own and competitors’ stockouts as a source of variation to the consumer choice set, in addition to variations in competitors’ prices. We estimate an empirical model capturing consumer choices among substitutable products from multiple retailers. Based on the estimates, we propose and test a best-response pricing strategy through a carefully controlled live experiment that lasts five weeks. The experiment documents an 11% revenue increase while maintaining a margin above a retailer-specified target. The e-companion is available at https://doi.org/10.1287/mnsc.2017.2753 .

Return to Invested Capital and the Performance of Mergers and Acquisitions
Authors: Qian Jun “QJ” , Zhu Julie Lei 
Published: June 2017

We evaluate the efficiency of capital deployment for acquiring firms before mergers and acquisitions (M&As), defined as the return on invested capital net of the cost of capital, and link this measure to firms’ postacquisition performance. Acquirers with higher preacquisition net returns on investment have superior long-run operating and stock performance than do acquirers with lower returns. Acquirers with low net returns on investment also underperform matching nonacquirers. The relationship between preacquisition investment return and postacquisition performance is weakened when chief executive officer turnover occurs after deal completion. These results imply that managerial ability in deploying capital and creating value for shareholders persists through M&As.

Serial Inventory Systems with Markov-Modulated Demand: Derivative Bounds, Asymptotic Analysis, and Insights
Authors: Chen Li , Song Jing-Sheng , Zhang Yue 
Published: June 2017

We study inventory control of serial supply chains with continuous, Markov-modulated demand (MMD). Our goal is to simplify the computational complexity by resorting to certain approximation techniques, and, in doing so, to gain a deeper understanding of the problem. First, we perform a derivative analysis of the problem’s optimality equations and develop general, analytical solution bounds for the optimal policy. This leads to simple-to-compute near-optimal heuristic solutions, which also reveal an intuitive relationship with the primitive model parameters. Second, we establish an MMD central limit theorem under long replenishment lead time through asymptotic analysis. We show that the relative errors between our heuristic and the optimal solutions converge to zero as the lead time becomes sufficiently long, with the rate of convergence being the square root of the lead time. Third, we show that, by leveraging the Laplace transform, the computational complexity of our heuristic is superior to the existing methods. Finally, we provide the first set of numerical study for serial systems under MMD. The numerical results demonstrate that our heuristic achieves near-optimal performance even under short lead times and outperforms alternative heuristics in the literature. In addition, we observe that, in an optimally run supply chain under MMD, the internal fill rate can be high and the demand variability propagating upstream can be dampened, both different from the system behaviors under stationary demand.

Published: June 2017

ABSTRACT
THE SNATCH BALANCE IS A TOTAL-BODY STRENGTH AND POWER EXERCISE THAT CAN BE PROGRAMMED IN SEVERAL WAYS, DEPENDING ON THE ABILITY OF THE ATHLETE AND JUDGMENT BY THE COACH. THIS LIFT CAN BE USED IN A PROGRESSION TOWARD LEARNING THE FULL SNATCH, USED TO HELP ATHLETES STRUGGLING WITH TECHNIQUE PATTERNS AND POSITIONAL STRENGTH IN THE FULL SNATCH, OR USED IN PLACE OF THE FULL SNATCH TO ELICIT POWER, STRENGTH, AND SPEED DEVELOPMENT. VARIATIONS OF OLYMPIC-STYLE LIFTS ARE ADVANTAGEOUS FOR TRAINING TOTAL-BODY EXPLOSIVE STRENGTH AND POWER BUT HAVE LESS TECHNICAL COMPLEXITY THAN THE FULL LIFTS. SPECIFICALLY, THE SNATCH BALANCE REQUIRES THE ATHLETE TO GENERATE FORCE INTO THE GROUND, PERFORM RAPID TRIPLE EXTENSION AT THE HIPS, KNEES, AND ANKLES TO PRESS THE BARBELL OVERHEAD, AND CATCH THE BARBELL IN AN OVERHEAD SQUAT POSITION.

En este artículo se pretende analizar la influencia que variables como el género, el hábitat, la titularidad del centro o la formación de los padres, tienen en el rendimiento obtenido por el alumnado en las pruebas para optar al premio extraordinario de la Educación Secundaria Obligatoria (ESO). Dado que para presentarse al premio el alumnado tuvo que tener una nota media de sobresaliente en toda la ESO, no cabe inicialmente esperar diferencias significativas según las variables analizadas.Para ello se procedió hacer una revisión de la literatura y se analizaron las notas obtenidas por 1.522 discentes durante el período 2008-2013, en Galicia (España), usando diversas metodologías de análisis como el Análisis de Varianza Unifactorial y Factorial, siendo el 63% del alumnado que se presentan a estas pruebas chicas, el 70,6% con padres universitarios, el 67,5% de ciudad y el 61,8% procedentes de la escuela pública.La principal conclusión es que estas variables influyen en el rendimiento de este colectivo de sobresaliente, siendo el perfil que obtiene mejor rendimiento el alumnado masculino con familia universitaria y que vive en la ciudad.
Práctica social y cultural del campesinado cafetero en cuatro municipios de Caldas (Colombia)
Authors: Parada Sanabria Pompeyo 
Published: June 2017

Este artículo, producto de una investigación realizada en el Departamento de Antropología y Sociología de la Universidad de Caldas, analiza las variables de índole sociocultural en los recolectores del café de la zona centro de Caldas, donde se encuentra la caficultura más tecnificada, y en pequeños productores cultivadores del grano de la zona norte y de la zona occidental, es decir, en cuatro municipios del departamento de Caldas. El estudio incluye las variables relaciones de familia, asociacionismo y sociabilidad, que conforman elementos significativos de la práctica social de estos dos grupos sociales, siguiendo la referencia metodológica de la identidad sociocultural propuesta por antropólogos de la Universidad de Sevilla. Se aplica esta metodología a los colectivos sociales de la caficultura caldense mencionados y se destaca la práctica social por fuera del ámbito productivo para diferenciar la descripción y el análisis de lo exclusivamente económico, tan predominante en este tipo de estudios, lo cual no significa que no se tome en cuenta este aspecto. Este artículo es fruto de un trabajo de campo que se hizo especialmente mediante la observación de los procesos de trabajo y de comportamiento en sitios distintos a los laborales durante periodos de cosecha y de tiempo “frío”. También se utilizaron entrevistas semiestructuradas y en profundidad a recolectores, pequeños productores, líderes de dos resguardos indígenas y a empleadores en veredas, fincas y sitios públicos de losmunicipios considerados representativos de ambos grupos sociales: Chinchiná y Palestina para los recolectores del café en épocas de cosecha y Riosucio y Salamina para el caso de los campesinos.
The problem of turbulence intensity measurement in comfort ventilation
Authors: Both B. , Szánthó Z. , Goda R. 
Published: June 2017

The turbulence intensity is an important feature of the turbulent airflow and draught sensation in ventilated rooms. The turbulence is often measured with hot-wire (in fluid mechanics applications) and hot-sphere sensors (in indoor air comfort investigations). In this paper the turbulence was measured with hot-wire and hot-sphere sensors in a full-scale single office room based on air speed measurements. Isothermal air injection was applied and the measurements were conducted on eight different inlet volume flow rates. The two applied sensors resulted two independent samples, which were evaluated with different statistical methods. The results showed that there was not significant difference between the standard deviation and average of the measured samples. Thus, the two sensors statistically gave the same results on probability level 95%.
The referred international standards suggest an average turbulence intensity 40% for draught comfort design in mixing ventilation. The results showed that most of the measured turbulence intensities were less than the recommended standard turbulence intensity.

Published: June 2017

Background: Tuberculin sensitivity and its relationship to nutritional status in inmates of children's home.Methods: Tuberculin sensitivity was checked in 180 apparently healthy orphan children and its relationship with nutritional status, previous vaccination status was studied. setting: children's home run by NGOs participants: all inmates of children's home aged 2-15 years who meet inclusion and exclusion criteria.Results: Out of 180 apparently healthy children 27 (15%) were tuberculin positive. 109 (60.5%) were undernourished children out of which 15 (55.56%) were tuberculin positive. Out of 71 normal nourished children, 12 (44.4%) were tuberculin positive. BCG scar was present in 120 (66.6%) children out of which 19 were tuberculin positive and BCG scar was absent in 60% children out of which 8 were tuberculin positive. 8 children had history of contact with TB and 6 of them were tuberculin positive.Conclusions: Tuberculin sensitivity testing using 5 TU PPD-RT23 is a simple feasible method to screen inmates of children home at the time of entry and it is not influenced by nutritional status or previous BCG vaccination. Early diagnosis and treatment of TB will go a long way in reducing the burden of TB in our country.

* Pediatric musculoskeletal infections are common, with variable presentations that are dependent on patient age, development, and disease severity. The current report focuses on a patient with pyomyositis.* Pyomyositis traditionally has been observed in tropical climates, but it is increasingly being noted in more moderate climates throughout the United States. It predominately affects males, and Staphylococcus aureus is the primary causative agent.* Children with suspected pyomyositis should be evaluated urgently for bacteremia. Diagnosis involves a thorough history and physical examination, with the understanding that the condition can present with a wide degree of variation.* Definitive treatment requires antibiotics and often operative intervention. Sequelae can occur.
