Literature Review of the Measurement in the Innovation Management
Organizations create innovation strategies to improve their productivity and the competitive advantage. In this sense, innovation management facilitates the realization of innovation. It is known that measurement is important in the management processes; however, there is no classification of the contributions in these subjects. Therefore, in this study we identify publications that involve measurement and analysis in the management of innovation. Our study used a systematic mapping of the literature and it shows that in recent years there has been an increase in research on measurement, however, there are few studies and only for certain industrial sectors, sizes of companies and countries. Hence, there is a little worked research space which can be more developed

Evaluación teórica de la capacidad de procesos de Rational Unifi ed Process respecto del MoProSoft
Determining the processes capabilities in companies that develop software is an issue that has gained interest because through them they can be classifi ed at a certain level of capability or maturity, depending on the model used. In addition, some companies have a set of established practices and working methods, in the case of Peru is often based on Rational Unifi ed Process (RUP). This paper presents the theoretical evaluation of the processes capabilities in the operation category of software processes model Moprosoft under the assumption that an organization has properly implemented a set of minimal elements of RUP.La determinación de la capacidad de los procesos en empresas que desarrollan software es un tema que ha cobrado interés, pues a través de ellas se las puede califi car en un determinado nivel de capacidad o madurez, según el modelo usado. Además, algunas empresas cuentan con un conjunto de prácticas y metodologías de trabajo establecidas, que en el caso del Perú es frecuente que se basen en Rational Unifi ed Process. En este trabajo, se presenta la evaluación teórica de las capacidades de los procesos en la categoría de operación del modelo de procesos de software MoProSoft bajo el supuesto que una organización tenga implementado de manera adecuada un conjunto mínimo de elementos de RUP
Boletín MOMENTO ECONÓMICO, año 2, núms. 25-26, Septiembre-Octubre 2012.
El regreso del Partido Revolucionario Institucional (PRI) a la Presidencia de la República, sin lugar a dudas, se trata de un cambio político que los expertos en la materia deberán precisar su magnitud e impacto; en cuanto a las expectativas del momento económico, el futuro inmediato y mediato de la economía mexicana, lo cual es materia de este Boletín (a principios de diciembre y antes de ser enviado el presupuesto) todavía es muy pronto para tener una evaluación completa y estricta, ya que se están planteando un conjunto de reformas con el objetivo de “mover al país”. En principio se habla de tres iniciativas (Reformas
Educativa, de Telecomunicaciones y a la Ley Nacional de Responsabilidad Hacendaria y Deuda Pública para entidades federativas y municipios). Asimismo, se ha insistido en Reformas a PEMEX para su apertura a la inversión priva-
da en refinación, petroquímica y transporte de hidrocarburos, además de la puesta en marcha de la Reforma Laboral, vigente a partir del pasado 1° de diciembre
Problemas en la adopción de modelos de gestión de servicios de tecnologías de información. Una revisión sistemática de la literatura
Ante el creciente uso de las tecnologías de información se han desarrollado modelos de gestión de servicios de tecnología de información (GSTI) con la finalidad que las organizaciones puedan ofrecer servicios de manera eficaz y con mayor nivel de calidad. Sin embargo, el cumplimiento de estos modelos no ha representado un trabajo fácil y las organizaciones han encontrado diversos problemas logrando adopciones parciales. El objetivo del estudio es analizar los problemas que las organizaciones han tenido en la adopción de un modelo de GSTI y para ello se ha realizado una revisión sistemática de la literatura. En la revisión se encontró que sólo algunos procesos fueron adoptados como parte de la implementación de los modelos y del análisis realizado podemos mencionar que las dificultades más recurrentes son: la falta de compromiso de la alta dirección y la falta de conocimiento sobre los modelos de GSTI y sus beneficios.Information technologies service management (ITSM) models have developed due to the increasing use of information technologies in order that organizations can deliver services efficiently and with a higher level of quality. However, models’ compliance has not been an easy job and the organizations have found problems achieving partial adoptions. The aim of this study is to analyze the problems that organizations had in the adoption of an ITSM model. To achieve this goal a systematic literature review was performed. The review confirmed that only some processes had adopted by the companies. The analysis shows us that more recurrent difficulties are lack of commitment from senior management and lack of knowledge about the ITSM model and its benefits

Assessment of Metabolic Phenotypes in Patients with Non-ischemic Dilated Cardiomyopathy Undergoing Cardiac Resynchronization Therapy
Studies of myocardial metabolism have reported that contractile performance at a given myocardial oxygen consumption (MVO2) can be lower when the heart is oxidizing fatty acids rather than glucose or lactate. The objective of this study is to assess the prognostic value of myocardial metabolic phenotypes in identifying non-responders among non-ischemic dilated cardiomyopathy (NIDCM) patients undergoing cardiac resynchronization therapy (CRT). Arterial and coronary sinus plasma concentrations of oxygen, glucose, lactate, pyruvate, free fatty acids (FFA), and 22 amino acids were obtained from 19 male and 2 female patients (mean age 56 ± 16) with NIDCM undergoing CRT. Metabolite fluxes/MVO2 and extraction fractions were calculated. Flux balance analysis (FBA) was performed with MetaFluxNet 1.8 on a metabolic network of the cardiac mitochondria (189 reactions, 230 metabolites) reconstructed from mitochondrial proteomic data (615 proteins) from human heart tissue. Non-responders based on left ventricular ejection fraction (LVEF) demonstrated a greater mean FFA extraction fraction (35% ± 17%) than responders [18 ± 10%, p = 0.0098, area under the estimated ROC curve (AUC) was 0.8238, S.E. 0.1115]. Calculated adenosine triphosphate (ATP)/MVO2 using FBA correlated with change in New York Heart Association (NYHA) class (rho = 0.63, p = 0.0298; AUC = 0.8381, S.E. 0.1316). Non-responders based on both LVEF and NYHA demonstrated a greater mean FFA uptake/MVO2 (0.115 ± 0.112) than responders (0.034 ± 0.030, p = 0.0171; AUC = 0.8593, S.E. 0.0965). Myocardial FFA flux and calculated maximal ATP synthesis flux using FBA may be helpful as biomarkers in identifying non-responders among NIDCM patients undergoing CRT
Decadal analysis of hydrography and in situ nutrient budgets in the western and eastern North Atlantic subtropical gyre
Author Posting. © American Geophysical Union, 2007. This article is posted here by permission of American Geophysical Union for personal use, not for redistribution. The definitive version was published in Journal of Geophysical Research 112 (2007): C07025, doi:10.1029/2006JC003788.The current debate about the mechanisms and magnitude of new nutrient input to the euphotic zone in subtropical gyres calls for studies which consider large and mesoscale perspectives by combining in situ time series and remote observations. We carried out a first of its kind comparative analysis of hydrography and sea level anomaly (SLA) at the oligotrophic time series stations BATS (Bermuda Atlantic Time Series Study) and ESTOC (European Station for Time Series, Canary Islands) using concomitant 10-yr in situ and satellite altimetry data. The stations are located at about the same latitude in the western and eastern boundaries of the subtropical North Atlantic gyre, respectively, and provide the opportunity to study differences that may exist between both regions. Observed SLA was 0.25 m at BATS, compared with 0.12 m at ESTOC, a consequence of the higher eddy kinetic energy in the western compared with the eastern subtropical gyre. We quantified a detailed in situ nutrient budget for both time series stations; ESTOC received about 75% of the nutrients available for new production at BATS (in average 0.28 mol N m−2 yr−1 compared with 0.38 mol N m−2 yr−1, respectively), but the difference was not significant. However, significant differences in input mechanisms existed between both stations; eddy pumping constituted the main new nutrient source BATS, whereas wintertime convection was the main nutrient supply mechanism at ESTOC. In addition, the nutricline was significantly shallower at ESTOC compared with BATS, partly compensating for shallower mixed-layer depths and SLA variability at the western station. We found considerable interannual variability in both eddy pumping and wintertime convection which may be related to NAO-induced changes in the pattern of the subtropical gyre.This work

Global injury morbidity and mortality from 1990 to 2017 : results from the Global Burden of Disease Study 2017
Correction:Background Past research in population health trends has shown that injuries form a substantial burden of population health loss. Regular updates to injury burden assessments are critical. We report Global Burden of Disease (GBD) 2017 Study estimates on morbidity and mortality for all injuries. Methods We reviewed results for injuries from the GBD 2017 study. GBD 2017 measured injury-specific mortality and years of life lost (YLLs) using the Cause of Death Ensemble model. To measure non-fatal injuries, GBD 2017 modelled injury-specific incidence and converted this to prevalence and years lived with disability (YLDs). YLLs and YLDs were summed to calculate disability-adjusted life years (DALYs). Findings In 1990, there were 4 260 493 (4 085 700 to 4 396 138) injury deaths, which increased to 4 484 722 (4 332 010 to 4 585 554) deaths in 2017, while age-standardised mortality decreased from 1079 (1073 to 1086) to 738 (730 to 745) per 100 000. In 1990, there were 354 064 302 (95% uncertainty interval: 338 174 876 to 371 610 802) new cases of injury globally, which increased to 520 710 288 (493 430 247 to 547 988 635) new cases in 2017. During this time, age-standardised incidence decreased non-significantly from 6824 (6534 to 7147) to 6763 (6412 to 7118) per 100 000. Between 1990 and 2017, age-standardised DALYs decreased from 4947 (4655 to 5233) per 100 000 to 3267 (3058 to 3505). Interpretation Injuries are an important cause of health loss globally, though mortality has declined between 1990 and 2017. Future research in injury burden should focus on prevention in high-burden populations, improving data collection and ensuring access to medical care.Peer reviewe
Estimating global injuries morbidity and mortality : methods and data used in the Global Burden of Disease 2017 study
Background While there is a long history of measuring death and disability from injuries, modern research methods must account for the wide spectrum of disability that can occur in an injury, and must provide estimates with sufficient demographic, geographical and temporal detail to be useful for policy makers. The Global Burden of Disease (GBD) 2017 study used methods to provide highly detailed estimates of global injury burden that meet these criteria. Methods In this study, we report and discuss the methods used in GBD 2017 for injury morbidity and mortality burden estimation. In summary, these methods included estimating cause-specific mortality for every cause of injury, and then estimating incidence for every cause of injury. Non-fatal disability for each cause is then calculated based on the probabilities of suffering from different types of bodily injury experienced. Results GBD 2017 produced morbidity and mortality estimates for 38 causes of injury. Estimates were produced in terms of incidence, prevalence, years lived with disability, cause-specific mortality, years of life lost and disability-adjusted life-years for a 28-year period for 22 age groups, 195 countries and both sexes. Conclusions GBD 2017 demonstrated a complex and sophisticated series of analytical steps using the largest known database of morbidity and mortality data on injuries. GBD 2017 results should be used to help inform injury prevention policy making and resource allocation. We also identify important avenues for improving injury burden estimation in the future.Peer reviewe
