This paper proposes an integrated method for estimating the manufacturing competitiveness of companies using their comparative performance in their manufacturing objectives. The developed method uses an extensive analysis of the literature along with expert analysis through the Delphi method to identify the factors influencing competitiveness in the industry under study. Different statistical coefficients such as Cronbach’s alpha, Kendall’s W, Fleiss’ kappa and Intraclass Correlation are used to assure reliability in the instruments and the experts’ opinion. Exploratory factor analysis (EFA) and a subsequent confirmatory factor analysis (CFA) are used as the means to obtain the measurement model with which to calculate an indicator of manufacturing competitiveness. An empirical case study using the proposed method is performed in a sample of apparel maquiladora plants.

Background Autism spectrum disorders (ASD) are a set of neurodevelopmental disorders marked by a lack of social interaction, restrictive interests, and repetitive behaviors. There is a paucity of pharmacological treatments to reduce core ASD symptoms. Various lines of evidence indicate that reduced brain muscarinic cholinergic receptor activity may contribute to an ASD phenotype. Methods The present experiments examined whether the partial M1 muscarinic receptor agonist, 5-(3-ethyl-1,2,4-oxadiazol-5-yl)-1,4,5,6-tetrahydropyrimidine hydrochloride (CDD-0102A), alleviates behavioral flexibility deficits and/or stereotyped motor behaviors in the BTBR mouse model of autism. Behavioral flexibility was tested using a reversal learning test. Stereotyped motor behaviors were measured by eliciting digging behavior after removal of nesting material in a home cage and by measuring repetitive grooming. Results CDD-0102A (0.2 and 0.6 mg/kg but not 1.2 mg/kg) injected prior to reversal learning attenuated a deficit in BTBR mice but did not affect performance in B6 mice. Acute CDD-0102A treatment (1.2 and 3 mg/kg) reduced self-grooming in BTBR mice and reduced digging behavior in B6 and BTBR mice. The M1 muscarinic receptor antagonist VU0255035 (3 mg/kg) blocked the effect of CDD-0102A on grooming behavior. Chronic treatment with CDD-0102A (1.2 mg/kg) attenuated self-grooming and digging behavior in BTBR mice. Direct CDD-0102A infusions (1 µg) into the dorsal striatum reduced elevated digging behavior in BTBR mice. In contrast, CDD-0102A injections in the frontal cortex were not effective. Conclusions The results suggest that treatment with a partial M1 muscarinic receptor agonist may reduce repetitive behaviors and restricted interests in autism in part by stimulating striatal M1 muscarinic receptors.

Klinefelter syndrome is a form of male hypogonadism due to testicular sclerohyalinosis with atrophy and azoospermia, which is the most common cause of male infertility. The syndrome is usually accompanied by metabolic, morphological, and neurobehavioral manifestations; Venous thromboembolic diseases such as deep vein thrombosis and pulmonary embolism. The existence of chronic thromboembolic pulmonary hypertension in patients with Klinefelter syndrome is scarce in the literature. We present the imaging and genetic analysis of a 37 -year-old male with a history of deep vein thrombosis who was admitted for exertional dyspnea.

Consumption of foods can be suppressed by two feeding system defense mechanisms: conditioned taste aversion (CTA) or taste avoidance learning (TAL). There is a debate in the literature about which form of intake suppression is caused by various aversive stimuli. For instance, illness-inducing stimuli like lithium chloride are the gold standard for producing CTA and external (or peripheral) painful stimuli, such as footshock, are the traditional model of TAL. The distinction between CTA and TAL, which have identical effects on intake, is based on differential effects on palatability. That is, CTA involves a decrease in both intake and palatability, whereas TAL suppresses intake without influencing palatability. We evaluated whether lactose, which causes gastrointestinal pain in adult rats, produces CTA or TAL. Using lick pattern analysis to simultaneously measure intake and palatability (i.e., lick cluster size and initial lick rate), we found that pairing saccharin with intragastric infusions of lactose suppressed both the intake and palatability of saccharin. These results support the conclusion that gastrointestinal pain produced by lactose malabsorption produces a CTA, not TAL as had previously been suggested. Furthermore, these findings encourage the view that the CTA mechanism is broadly tuned to defend against the ingestion of foods with aversive post-ingestive effects.

Ingeniería Industrial - Abstract
La globalización ha abierto mercados para que las empresas sean libres de ofrecer sus bienes y servicios o adquirirlos de cualquier proveedor en el mundo. Este paradigma ha fomentado el desarrollo de una industria de ensamblaje intensiva en mano de obra, orientada a la exportación, conocida en América Latina como la Industria Maquiladora, que es uno de los sectores industriales más importantes de América Central y el Caribe. La competencia planteada por la globalización ha obligado a las maquiladoras a buscar aumentar su competitividad para mantenerse en el mercado. El uso de herramientas de manufactura avanzada (AMT) en sus operaciones de fabricación promete ayudarlos a mejorar su rendimiento y competitividad reduciendo costes, mejorando la calidad, aumentando la variedad de sus productos y optimizando la cadena logística Esta tesis propone un método para estimar la competitividad de fabricación de las maquiladoras en la industria de la confección y la influencia que los AMT tienen en esa competitividad. El método propuesto utiliza el análisis experto a través del método Delphi, el análisis no paramétrico, de correlación y factorial, así como el modelado de ecuaciones estructurales para estimar la competitividad de fabricación e identificar la influencia que las herramientas AMT tienen sobre dicha competitividad. Se realizó un estudio de caso empírico utilizando el método propuesto en una muestra de maquiladoras de ropa en Honduras. Los resultados de la prueba empírica muestran un efecto positivo entre el uso de AMT y la competitividad de fabricación, especialmente en el tiempo de entrega, el coste y la protección del medio ambiente. ----------ABSTRACT---------- Globalization has opened markets so that companies are free to offer their goods and services or to acquired them from any supplier in the world. This paradigm has fostered the development of a labor intensive, export-oriented assembly industry known in Latin America as Maquiladora Industry, which is one of the most important industrial sectors in Central America and the Caribbean. The competition posed by globalization has forced Maquiladoras to seek to increase their competitiveness in order to stay in the market. The use of advanced manufacturing tools (AMTs) in their manufacturing operations promises to help them improve their performance and competitiveness by reducing costs, improving quality, increasing the variety of their products and optimizing the logistic chain. This thesis proposes a method for estimating the manufacturing competitiveness of maquiladoras in the apparel industry and the influence that AMTs have on that competitiveness. The proposed method uses expert analysis through the Delphi method, non-parametric, correlation and factor analysis as well as structural equation modelling for estimating manufacturing competitiveness and identifying the influence that AMT has on that competitiveness. An empirical case study using the proposed method was performed in a sample of apparel maquiladora plants in Honduras. The results of the empirical test show a positive effect between AMTs use and manufacturing competitiveness, especially in the delivery time, cost and environmental protection.

La globalización ha creado la necesidad que las industrias maquiladoras replanteen sus estrategias y procedimientos para volverse más competitivas y poder de esta forma mantenerse en el mercado. Para poder lograr esta competitividad, las empresas deben establecer estrategias de manufactura que estén enfocadas en satisfacer las necesidades específicas de los clientes. Las necesidades de los clientes pueden modelarse en base al énfasis que estos colocan a ciertas prioridades que compiten entre sí. Una empresa que logra entender bien cuáles son estas prioridades; y luego trabaja para que su estrategia de manufactura responda a estas necesidades logrará posicionarse positivamente sobre sobre su competencia. Este artículo propone un instrumento y metodología que permita identificar las prioridades competitivas del mercado maquilador, así como un indicador que determine que tan bien alineada esta una empresa con dichas prioridades meta. Para hacerlo se ha hecho un extenso análisis de la literatura y se han realizado entrevistas con expertos para probar la validez de constructo del instrumento diseñado.
