Nothing in the History of Spanish <Emphasis Type="Italic">Anís</Emphasis> Makes Sense,Except in the Light of Evolution     

Juan Antonio Delgado  Ricardo Luis Palma 《Science & Education》2011,20(2):141-157

We describe, discuss and illustrate a metaphoric parallel between the history of the most famous Spanish liqueur, “Anís del Mono” (Anís of the Monkey), and the evolution of living organisms in the light of Darwinian theory and other biological hypotheses published subsequent to Charles Darwin’s Origin of Species. Also, we report the use of a caricature of a simian Darwin with a positive connotation, perhaps the only one ever produced. We conclude that, like some species in the natural world, Anís of the Monkey has evolved, adapted, survived and become the fittest and most successful anís in the Spanish market and possibly the world. We hope this paper will contribute a new useful metaphor for the teaching of biological evolution.  相似文献   

Assessment of total body water and its compartments in elite judo athletes: comparison of bioelectrical impedance spectroscopy with dilution techniques     

Ezequiel M. Gonçalves  Catarina N. Matias  Diana A. Santos  Luis B. Sardinha  Analiza M. Silva 《Journal of sports sciences》2015,33(6):634-640

Bioelectrical impedance spectroscopy (BIS) is an inexpensive and non-invasive technique to measure total body water (TBW), extracellular water (ECW), and intracellular water (ICW). The purpose of this study was to validate TBW, ECW and ICW assessed by BIS, using dilution techniques as the reference method (REF) in elite judo athletes. Thirty-two Portuguese elite male judo athletes were evaluated during a period of weight stability. TBW, ECW and ICW were assessed by BIS (Xitron 4000). Deuterium and bromide dilution techniques were used as the criterion method for measuring TBW and ECW, while ICW was calculated as the difference between the two. BIS explained 96%, 77% and 94% of the total variability from REFs for TBW, ECW and ICW, respectively. BIS also demonstrated high precision (ρ ≥ 0.88) and accuracy (C_b = 0.98), with a minimum concordance coefficient correlation of 0.87 for ECW. The mean bias demonstrated that BIS slightly overestimated the REF in 1.1 kg (2.3%), 0.3 kg (1.6%) and 0.8 kg (2.7%) for TBW, ECW and ICW, respectively. The 95% limits of agreement ranged from ?1.2 to 3.3 kg in TBW, from ?1.8 to 2.4 kg in ECW and from ?1.0 to 2.6 kg in ICW. A non-significant trend was found between the difference and the mean of reference and alternative methods. These findings highlight the efficacy of BIS as a valid non-biased tool for the assessment of TBW and its compartments in elite male judo athletes, during a period of weight stability.  相似文献

Ecotoxicity assessment using ciliate cells in millifluidic droplets     

Rico Illing  Corinna Burkart  Daniel Pfitzner  Dirk Jungmann  Larysa Baraban  Gianaurelio Cuniberti 《Biomicrofluidics》2016,10(2)

Precise analysis of the aquatic cells and their responses to the toxic chemicals, i.e., water disinfective agents, is of crucial importance due to their role in the ecosystem. We demonstrate the application of the droplets based millifluidic tool for isolating and longtime monitoring of single Paramecium tetraurelia cells using a large number of water-in-oil emulsion droplets. Due to the automated monitoring of the fluorescence signal, the droplets containing cells are distinguished from the empty reservoirs. A viability indicator is used to follow the metabolic dynamic of the cells in every single droplet. Finally, we perform ecotoxicity tests in droplets, exposing the encapsulated paramecia cells to silver nitrate for determination of EC50 levels, and compare the output with the conventional microtiter plate assay.  相似文献   

El diagnóstico y tratamiento de las dislexias ante un modelo de lectura normal     

Luis Lozano 《Infancia y Aprendizaje》2013,36(64):111-126

Resumen

El objetivo fundamental de este trabajo es triple. Por una parte se expone el marco general que se asume. El modelo de lectura de doble ruta, encuadrado en los trabajos sobre el Procesamiento de la Información, propone una arquitectura funcional determinada por un número determinado de módulos con unas específicas comunicaciones entre ellos. A partir de aquí, conjuntamente con los datos experimentales que se conocen sobre cómo funciona la lectura en los buenos lectores, se utiliza para elaborar un diagnóstico de las dificultades lectoras. Este diagnóstico buscará el conocimiento de aquellas habilidades específicas que tienen que ver con la lectura y que por diversas circunstancias no funcionan adecuadamente. Por último, se planifica el tratamiento específico dirigido exclusivamente a los aspectos pertienentes a la lectura, sin divagar sobre otros aspectos clásicos (psicomotricidad, later alidad, etc.) que nada tienen que ver con la lectura.  相似文献

Prediction of abandonment in Spanish fitness centres     

Iván Clavel San Emeterio  Jorge García-Unanue  Eliseo Iglesias-Soler  Jose Luis Felipe  Leonor Gallardo 《European Journal of Sport Science》2019,19(2):217-224

Research question: The increase of physical exercise in fitness centres has turned these facilities in important active lifestyle promoters. However, only between 30% and 60% of subscribers still linked to the sports centre after a year. The aim of this study is to design a model to predict the drop out in fitness centres. Research methods: Monthly data corresponding to the actual behaviour of 14,522 members of three sport centres in Spain were recorded over the course of one year. In order to calculate the likelihood of drop out, logistic regressions were used to create predictive models for each centre. Results and findings: It was possible to predict abandonment of users of sport centres from their historical behaviour, although the predictive models obtained for each centre were not completely coincident. The effectiveness of the models was around 70%. Implications: The analysis of users’ behaviour in a fitness centre can allow to avoid the drop out and therefore the abandonment of physical activity. Segmenting the customers based on the likelihood of drop out may be useful for improving the effectiveness of the strategies of loyalty and for optimizing the organization of human and material resources.  相似文献   

Validity of a single lactate measure to predict fixed lactate thresholds in athletes     

Ibai Garcia-Tabar  Iñaki Llodio  Luis Sánchez-Medina  Xabier Asiain  Javier Ibáñez 《Journal of sports sciences》2017,35(4):385-392

This study aimed to validate the use of a single blood lactate concentration measure taken following a 12 km h^?1 running stage (BLC₁₂) to predict and monitor fixed blood lactate concentration (FBLC) thresholds. Three complementary studies were undertaken. Study I: the relationships between BLC₁₂ and the running speeds at FBLC of 3 mmol L^?1 (S3mM) and 4 mmol L^?1 (S4mM) measured during a multistage running field test were examined in 136 elite athletes. Study II: data from 30 athletes tested one year apart were used to test the predictive capacity of the equations obtained in Study I. Study III: 80 athletes were tested before and after an intensified training period to examine whether training-induced changes in FBLC thresholds could be predicted and monitored by BLC₁₂. Study I: BLC₁₂ was significantly (P < 0.001) and inversely related to S3mM (R² = 0.89) and S4mM (R² = 0.95). Study II: prediction models yielded robust correlations between the estimated and measured FBLC thresholds (r = 0.94–0.99; P < 0.001). Study III: estimated changes predicted actual training-induced changes in FBLC thresholds (r = 0.81–0.91; P < 0.001). This study gives empirical support to use a single lactate measure during a sub-maximal running field test as a simple, low-cost and practical alternative to FBLC thresholds in athletes.  相似文献   

The Virtual Office: A Behavior Engineering Model (BEM) Perspective     

John Austin  Luis Gamier 《Performance Improvement Quarterly》1998,11(4):7-21

Information technology (IT) has become a powerful tool in today's business world. One specific impact of IT has been the development of the virtual office and organization. This paper discusses some issues associated with the virtual office. Some advantages and disadvantages of the virtual office are summarized from both employees' and employers' perspectives. The behavior engineering model (BEM) developed by Thomas Gilbert (1996) is used as a framework to analyze the different factors related to performance in the virtual office. Additionally, the application of other concepts from human performance technology (HPT) and organizational behavior management (OBM) perspectives are suggested. Some future research guidelines are discussed and the need to further develop experimental and more controlled data-based studies are pointed out.  相似文献
