Linearly Transforming Variables in the VAR Model, How Does it Change the Impulse Response?
Authors: Reusens Peter , Croux Christophe 
Published: July 2017

AbstractThis paper analyzes the impulse response function of vector autoregression models for variables that are linearly transformed. The impulse response is equal to the linear transformation of the original impulse response if and only if the shock is equal to the linear transformation of the original shock. In particular, we consider shocks in one error term only, generalized shocks, structural shocks identified by short-run recursive restrictions and structural shocks identified by long-run recursive restrictions. A vector autoregression model with expected inflation, the overnight rate and a long term ex-ante real interest rate that replaces the corresponding long term nominal interest rate, illustrates our results.
Application of Computational Methods in Planaria Research: A Current Update
Authors: Ghosh Shyamasree 
Published: July 2017

AbstractPlanaria is a member of the Phylum Platyhelminthes including flatworms. Planarians possess the unique ability of regeneration from adult stem cells or neoblasts and finds importance as a model organism for regeneration and developmental studies. Although research is being actively carried out globally through conventional methods to understand the process of regeneration from neoblasts, biology of development, neurobiology and immunology of Planaria, there are many thought provoking questions related to stem cell plasticity, and uniqueness of regenerative potential in Planarians amongst other members of Phylum Platyhelminthes. The complexity of receptors and signalling mechanisms, immune system network, biology of repair, responses to injury are yet to be understood in Planaria. Genomic and transcriptomic studies have generated a vast repository of data, but their availability and analysis is a challenging task. Data mining, computational approaches of gene curation, bioinformatics tools for analysis of transcriptomic data, designing of databases, application of algorithms in deciphering changes of morphology by RNA interference (RNAi) approaches, understanding regeneration experiments is a new venture in Planaria research that is helping researchers across the globe in understanding the biology. We highlight the applications of Hidden Markov models (HMMs) in designing of computational tools and their applications in Planaria decoding their complex biology.

Authors: Huang Han-Liang , Guo Yuting 
Published: July 2017

Abstract
The intuitionistic fuzzy set is a useful tool to deal with vagueness and uncertainty. Correlation coefficient of the intuitionistic fuzzy sets is an important measure in intuitionistic fuzzy set theory and has great practical potential in a variety of areas, such as decision making, medical diagnosis, pattern recognition, etc. In this paper, an improved correlation coefficient of the intuitionistic fuzzy sets is defined, and it can overcome some drawbacks of the existing ones. The properties of this correlation coefficient are discussed. Then, the generalization of the coefficient of interval-valued intuitionistic fuzzy sets is also introduced. Finally, two examples about the application of the proposed correlation coefficient of the intuitionistic fuzzy sets in medical diagnosis and clustering are shown to illustrate the advantages over the existing methods.

Authors: Jahanfar Shayesteh , Lim Kenneth , Ovideo-Joekes Eugenia 
Published: July 2017

AbstractObjective:Our purpose was to examine the association between discordant growth and perinatal mortality and morbidity among twins with careful adjustment for maternal confounding factors.Study design:Two cohorts with and without chorionicity data were compared using generalized estimating modeling.Results:Our population-based dataset consisted of 12,656 individual twins from whom 4% (452/12,656) had≥30% growth discordance. A subgroup of this population with chorionicity information had an incidence of 7.3%≥30% growth discordance. In growth-discordant twins, perinatal mortality and morbidity were higher than concordant pairs (P<0.01). Low Apgar score and perinatal mortality were more frequent in growth-discordant twins compared with growth-concordant ones (all P<0.01).Conclusion:Birth weight discordance (BWD) places twins at increased risk of perinatal mortality. Growth discordance was also an independent risk factor for lower Apgar score of 5 min less than 5.

Abstract
Wagner, H, Gierlinger, M, Adzamija, N, Ajayi, S, Bacharach, DW, and von Duvillard, SP. Specific physical training in elite male team handball. J Strength Cond Res 31(11): 3083–3093, 2017—Specific physical training in elite team handball is essential for optimal player's performance; however, scientific knowledge is generally based on temporary training studies with subelite athletes. Therefore, the aim of the study was to analyze the effects of specific physical training in an elite male handball team over the entire season. Twelve players of a male handball team from the First Austrian Handball League conducted a 1-year specific physical training program in addition to their normal (team handball techniques and tactics) weekly training. Performance was measured with 5 general and 4 specific tests as well as game statistics during competition. Repeated measures analysis of variances and paired sample t-test were used to analyze differences in performance during training. We found a significant increase in oxygen uptake, offense time, defense time, fast break time, and jump height in the specific tests. Game performance statistics revealed a lower throwing percentage in the hosting team (59%) compared with the rival teams (63%). Our results indicated that specific endurance and agility are an acceptable modality in elite male team handball. However, performance in competition is strongly influenced by specific techniques and tactics. We recommend to strength and conditioning professionals that they tailor strength and power training, coordination and endurance as specific as possible, using free weights, agility exercises that include change in direction and jumps as well as short (10–15 seconds) high-intensity intervals.

Abstract
Masumoto, K, Mefferd, KC, Iyo, R, and Mercer, JA. Muscle activity and physiological responses during running in water and on dry land at submaximal and maximal efforts. J Strength Cond Res 32(7): 1960–1967, 2018—We investigated muscle activity, oxygen uptake, heart rate, and rating of perceived exertion during running in water and on dry land at submaximal and maximal efforts. Eleven recreational runners performed deep-water running (DWR) and treadmill running (TMR) graded exercise tests on separate days. On the third-test day, the subjects exercised at their 60, 80, and 100% of maximal oxygen uptake (V̇o
2max) by matching specific stride frequencies or running speeds. V̇o
2max, maximal heart rate (HRmax), and rating of perceived exertion at maximal effort (RPEmax) were measured. Furthermore, muscle activity from the rectus femoris, biceps femoris, tibialis anterior, and gastrocnemius were measured. V̇o
2max (DWR: 48.9 ± 5.7 ml·kg−1·min−1; TMR: 59.2 ± 5.6 ml·kg−1·min−1; p < 0.001) and HRmax (DWR: 174.1 ± 9.6 beats·min−1; TMR: 191.2 ± 6.9 beats·min−1; p < 0.001) were each lower during DWR vs. TMR. In addition, RPEmax was not significantly different between DWR and TMR (DWR: 17.8 ± 1.9; TMR: 18.4 ± 1.3; p > 0.05). Furthermore, muscle activity from all tested muscles was not influenced by the interaction of mode and intensity (p > 0.05). Muscle activity from all tested muscles was different between modes (p < 0.05) and between intensities (p < 0.001). Specifically, muscle activity from the tested muscles during DWR was 29–69% lower than that of TMR at maximal effort. Athletes and coaches should consider that the exercise intensity during DWR can be overestimated, if exercise prescription was made according to the maximal responses during TMR.
AGOSTINHO FRENTE AOS CÉTICOS ACADÊMICOS
Authors: Paolozzi Mariana 
Published: July 2017

Este artigo ressalta alguns aspectos da crítica agostiniana aos céticos acadêmicos. Tentando demonstrar que é possível alcançar a verdade, Agostinho discute um dos grandes problemas da filosofia, o do conhecimento e da certeza. Ele aborda esse tema principal a partir da interrogação dos filósofos acadêmicos: a filosofia consiste somente na “busca” (investigatio), talvez vã, ou consiste na “descoberta” (inventio) da verdade? Será feita uma análise do diálogo agostiniano Contra Academicos a partir de seu pano de fundo, que nos situa no horizonte da filosofia dos acatalépticos (acadêmicos) e do materialismo, tanto estóico quanto epicurista. O desafio de Agostinho será o de suplantar não apenas os acadêmicos, mas deverá fazê-lo sem afirmar o materialismo estoico (e muito menos o epicurista). As obras posteriores de Agostinho que abarcam esse tema desenvolvem os principais argumentos desse diálogo da juventude que, portanto, pode ser considerado a principal fonte a respeito do assunto.
PRINCIPAIS ACONTECIMENTOS OCORRIDOS EM INSTITUIÇÕES FEDERAIS QUE PODEM IMPACTAR NA CAPACIDADE ESTRATÉGICA DE RESILIÊNCIA – GESTÃO DA COORDENAÇÃO DE CURSOS/MAIN EVENTS OCCURRED IN FEDERAL INSTITUTIONS, WHICH MAY IMPACT ON THE STRATEGIC RESILIENCE CAPACITY - MANAGEMENT COURSE COORDINATION
Authors: Nogueira Maria da Graça Saraiva , De Melo Pedro Antônio 
Published: July 2017

O objetivo deste estudo foi analisar os principais acontecimentos ocorridos nos últimos 10 anos em instituições de ensino superior, que impactam na capacidade estratégica de resiliência de coordenações de curso na gestão de suas atividades diárias. A pesquisa contou com quarenta e três coordenadores de duas Instituições de Ensino Superior Públicas com diferenças significativas em relação ao número de alunos, da relação candidato/vaga e do ranking do e-MEC. A metodologia utilizada foi a pesquisa de abordagem qualitativa, com amostra intencional de coordenadores de curso das instituições pesquisadas. As análises dos acontecimentos apontam que apesar das diferenças significativas em relação às instituições, podemos considerar que o impacto dos acontecimentos ocorridos nos últimos dez anos se apresenta intensa e efetivamente na capacidade estratégica de resiliência na gestão diária de coordenadores de curso das instituições federais. Considera-se que os coordenadores de curso apresentam capacidade estratégica de resiliência no processo de tomada de decisão nas suas atividades, levando em conta o tempo de atuação na instituição e dos acontecimentos vivenciados no período de sua gestão.

Published: July 2017

O foco central desta pesquisa exploratório-descritiva foi realizar uma análise prévia da existência da relação entre a posição do país no ranking TTCI (Tourism & Travel Competitivenes Index) e a sua produção turística, no que tange as variáveis que impactam sobre a população, as empresas e o setor público. O objetivo era verificar se estes índices demostram uma visível relação de causa-efeito com a produção do setor. Os resultados para os 10 países americanos mais competitivos mostrou que a pontuação do ranking TTCI não serviu para indicar o panorama de crescimento da produção turística. Por outro lado, o posicionamento competitivo que o TTCI frente ao contexto mundial foi um índice corroborado pelos indicadores econômicos de produtividade. Na maioria dos países analisados ao subir de posicionamento competitivo houve uma maior geração de empregos, melhoras no PIB turístico e maior gasto do turista estrangeiro no país. A principal implicação dos resultados deste trabalho é ressaltar o caráter relativo do construto competitividade permitindo uma melhor compreensão do uso destes monitores mundiais para os decisores políticos e empresariais.
Decomposing the Site Frequency Spectrum: The Impact of Tree Topology on Neutrality Tests

Published: July 2017

AbstractWe investigate the dependence of the site frequency spectrum on the topological structure of genealogical trees. We show that basic population genetic statistics, for instance, estimators of θ or neutrality tests such as Tajima’s D, can be decomposed into components of waiting times between coalescent events and of tree topology. Our results clarify the relative impact of the two components on these statistics. We provide a rigorous interpretation of positive or negative values of an important class of neutrality tests in terms of the underlying tree shape. In particular, we show that values of Tajima’s D and Fay and Wu’s H depend in a direct way on a peculiar measure of tree balance, which is mostly determined by the root balance of the tree. We present a new test for selection in the same class as Fay and Wu’s H and discuss its interpretation and power. Finally, we determine the trees corresponding to extreme expected values of these neutrality tests and present formulas for these extreme values as a function of sample size and number of segregating sites.

Published: July 2017

OBJECTIVES:
To implement data-driven vital sign parameters to reduce bedside monitor alarm burden.

METHODS:
Single-center, quality-improvement initiative with historical controls assessing the impact of age-based, inpatient-derived heart rate (HR) and respiratory rate (RR) parameters on a 20-bed acute care ward that serves primarily pediatric cardiology patients. The primary outcome was the number of alarms per monitored bed day (MBD) with the aim to decrease the alarms per MBD. Balancing measures included the frequency of missed rapid response team activations, acute respiratory code events, and cardiorespiratory arrest events in the unit with the new vital sign parameters.

RESULTS:
The median number of all cardiorespiratory monitor alarms per MBD decreased by 21% from 52 (baseline period) to 41 (postintervention period) (P &lt; .001). This included a 17% decrease in the median HR alarms (9–7.5 per MBD) and a 53% drop in RR alarms (16.8–8.0 per MBD). There were 57 rapid response team activations, 8 acute respiratory code events, and no cardiorespiratory arrest events after the implementation of the new parameters. An evaluation of HRs and RRs recorded at the time of the event revealed that all patients with HRs and/or RRs out of range per former default parameters would also be out of range with the new parameters.

CONCLUSIONS:
Implementation of data-driven HR and iteratively derived RR parameters safely decreased the total alarm frequency by 21% in a pediatric acute care unit.

Published: July 2017

The aim of the study was to evaluate the presence and characteristics of dental modifications in pre-Columbian populations from three archaeological sites in the Costa Rican territory (Nacascolo, Jícaro and La Cascabel) in order to describe them according to previous classification. Specimens were obtained from the collections of the National Museum of Costa Rica. All specimens were macroscopically analyzed and the pieces were classified. Photographic records were taken to each piece and a full description was done. Sixty one pieces with dental modifications were found. The types of dental modifications found were classified as A1, C2/C6, A2, C2, C1, E1 and A3 in order of prevalence. In conclusion, dental modifications were found in most of specimens. Particularly, C2/C6 modification was not reported by previous classifications.

Published: July 2017

Desde la introducción de los cultivos genéticamente modificados (GM), ha habido un crecimiento continuo en adopción de la tecnología y en la comercialización de alimentos y piensos derivados de cultivos GM alrededor del mundo. Gobiernos y organizaciones han desarrollado métodos para detectar rápidamente y con alto rendimiento los alimentos y piensos derivados de cultivos GM, y así verificar el cumplimiento de las regulaciones dirigidas a proveer información al consumidor. El objetivo de este estudio fue determinar la presencia de secuencias de ADN derivadas de maíz y soya GM, en una gama de piensos y alimentos, sin procesar y procesados, comercializados en Costa Rica, un mercado sin regulaciones que indiquen contenido transgénico en el etiquetado. Se empleó el método cualitativo estándar, de reacción en cadena de la polimerasa (PCR) en punto final, para la detección de material GM a partir las regiones comunes del promotor 35S y el terminador NOS, seguido de la detección específica de los eventos de maíz Bt11, MON810, GA21 y NK603, así como el evento de soya GTS 40-3-2, en una selección de alimentos y piensos disponibles en Costa Rica. Los resultados generales de la detección de secuencias derivadas de cultivos GM fueron: 86% para el promotor 35S, 72% para el terminador NOS y 40% para los eventos identificados. Los eventos más frecuentemente detectados fueron MON810, NK603 y Bt11. Los resultados demostraron que existen alimentos y piensos derivados de cultivos GM en el mercado local y que la significancia y viabilidad del etiquetado de los productos, para proveer información a los consumidores, debería ser abordado por las autoridades competentes. Sin embargo, todavía falta realizar estudios cuantitativos en los análisis de rutina, para detectar si el límite de material GM, establecido por la regulación sobre alimentos y piensos GM de la Unión Europea, se ha extralimitado.
A Google Earth Database of Central American Volcanic Vents
Authors: Carr Michael J. 
Published: July 2017

Satellite imagery in Google Earth reveals 807 volcanic vents for Central America. Most of these have already been recognized. In fact, previous catalogs include many volcanoes that are not obvious in Google Earth and they are not included here. Furthermore, 47 large but deeply eroded volcanoes are not included because they appear very old. On the other hand, many young vents may be obscured in areas of low quality imagery or in areas of dense cloud forest. High quality Google Earth coverage keeps expanding so this catalog can be improved with time. Lidar imagery would greatly improve vent detection. A significant problem with any list of volcanic features is determining the appropriate cutoff age. Topographic expression is the only available criterion for estimating age for most of the vents and this criterion is highly flawed because of differences in volcanic deposits, weathering, annual rainfall and other factors. Ideally, 40Ar/39Ar ages would be available for most of the volcanoes and the revealed space-time pattern of volcanic activity would allow improved hazard estimates as well as a deeper understanding of the causes and controls of volcanism. Instead, the database is a necessary step toward: a) recognizing important volcanological problems that can attract geochronological research funding and b) encouraging a long-term campaign for determining the temporal development of Central American volcanism. The database is intended as a draft to be used and improved, not a fixed list.
