John Tzetzes and the pseudo-Aristotelian Peplos in middle-Byzantium. The testimony of the Matritenses 4562 and 4621

Tras mi reciente edición de los pseudo-aristotélicos Pepli Epitaphia, el presente trabajo se centra en los apochrypha a dichos epitafios que compuso Juan Tzetzes en el siglo xii, un conjunto de ocho dísticos elegíacos para los héroes que consideró meritorios de tal tarea, y para quienes no pudo encontrar un epitafio conservado en las fuentes manuscritas a las que tuvo acceso. Para lograr dicho propósito, también se investiga el grado de conocimiento y la transmisión de ese corpus epigramático en la literatura bizantina, además de considerar las lecciones y el sentido mismo de dos códices guardados en la Biblioteca Nacional de España (M y Md). En ellos, Constantino Láscaris copió, directamente a partir de Tzetzes, dos breves antologías de dichos componentes.

Grammar in dictionaries revisited: the case of verbs with se

This paper is a study about the way in which se structures are represented in 20 verb entries of nine dictionaries of Spanish language. There is a large number of these structures and they are problematic for native and non native speakers. Verbs of the analysis are middle-high frequency and, in the most part of the cases, very polysemous, and this allows to observe interconnections between the different se structures and the different meanings of each verb. Data of the lexicographic analysis are cross-checked with corpus analysis of the same units. As a result, it is observed that there is a large variety in the data which are offered in each dictionary and in the way they are offered, inter and intradictionary. The reasons range from the theoretical overall of each Project to practical performance. This leads to the conclusion that it is necessary to further progress in the dictionary model it is being handled, in order to offer lexico-grammatical phenomenon such as se verbs in an accurate, clear and exhaustive way.

The Antibiotic Resistance and Prescribing in European Children Project: A Neonatal and Pediatric Antimicrobial Web-based Point Prevalence Survey in 73 Hospitals Worldwide

BACKGROUND: The neonatal and pediatric antimicrobial point prevalence survey (PPS) of the Antibiotic Resistance and Prescribing in European Children project (http://www.arpecproject.eu/) aims to standardize a method for surveillance of antimicrobial use in children and neonates admitted to the hospital within Europe. This article describes the audit criteria used and reports overall country-specific proportions of antimicrobial use. An analytical review presents methodologies on antimicrobial use.

METHODS: A 1-day PPS on antimicrobial use in hospitalized children was organized in September 2011, using a previously validated and standardized method. The survey included all inpatient pediatric and neonatal beds and identified all children receiving an antimicrobial treatment on the day of survey. Mandatory data were age, gender, (birth) weight, underlying diagnosis, antimicrobial agent, dose and indication for treatment. Data were entered through a web-based system for data-entry and reporting, based on the WebPPS program developed for the European Surveillance of Antimicrobial Consumption project.

RESULTS: There were 2760 and 1565 pediatric versus 1154 and 589 neonatal inpatients reported among 50 European (n = 14 countries) and 23 non-European hospitals (n = 9 countries), respectively. Overall, antibiotic pediatric and neonatal use was significantly higher in non-European (43.8%; 95% confidence interval [CI]: 41.3-46.3% and 39.4%; 95% CI: 35.5-43.4%) compared with that in European hospitals (35.4; 95% CI: 33.6-37.2% and 21.8%; 95% CI: 19.4-24.2%). Proportions of antibiotic use were highest in hematology/oncology wards (61.3%; 95% CI: 56.2-66.4%) and pediatric intensive care units (55.8%; 95% CI: 50.3-61.3%).

CONCLUSIONS: An Antibiotic Resistance and Prescribing in European Children standardized web-based method for a 1-day PPS was successfully developed and conducted in 73 hospitals worldwide. It offers a simple, feasible and sustainable way of data collection that can be used globally.

Pérdida de la biomasa en Eucalyptus camaldulenses dehnh en el proceso de campo, patio de acopio y astillero en el Ingenio San Antonio, Chinandega.

En los años 80 se creó dentro en el Ingenio San Antonio el Proyecto Forestal, en el municipio de Chichigalpa, departamento de Chinandega; y es así como inician las primeras actividades de producir madera de Eucalipto camaldulenses Dehnh. Actualmente en el Proyecto Forestal del Ingenio San Antonio, se carece de datos cuantitativos que representen porcentualmente la pérdida de biomasa que sufre la madera en el lapso de tiempo desde su corta, hasta su fundición en las calderas. El propósito de este estudio es proveer información de las cantidades de biomasa que se pierde en la madera de Eucaliptus camaldulenses Dehnh desde la etapa de corta en la plantación, hasta el patio de acopio y astilladora del Ingenio. En este estudio se establecieron parcelas de 20 m x 10 m (200 m2) dispersas en el lote próximo a aprovechamiento; dentro de estas parcelas se establecieron parcelas útiles de 16 m x 8 m (128 m2), abarcando un total de 8 árboles y seleccionar 2 árboles para seccionarlos en: Follaje, ramas grandes, ramas pequeñas, fuste y sistema radicular, de cada uno se obtuvo el peso verde, se extrajeron muestras de 500 gr de cada sección, con el fin de determinar el contenido de biomasa seca de la madera de Eucaliptus camaldulenses Dehnh. Se pretendió de igual manera, a través de mediciones de peso a los 5, 10, y 20 días evaluar la pérdida de humedad que experimenta la madera durante 20 días que es depositada en el patio de acopio y con el análisis del peso de las trozas después de los 20 días y el peso de los residuos de estas, determinar en contenido de biomasa perdida en la astilladora. En este estudio se encontró que el contenido de biomasa total en promedio sumando el follaje, ramas grandes, ramas pequeñas, fuste y sistema radicular de los árboles estudiados en la plantación fue de 0.07040 ton, lo que equivale a (0.19556 ton/ha). En promedio la pérdida de humedad que sufren las trozas a la entrada al patio de acopio a los veinte días es de 24.59 kg (0.02459 ton), lo que equivale a 28.90 % del peso original de cada troza. La pérdida de biomasa en el astillado, en promedio se encontró que fue de 2 kg (0.002 ton), en porcentaje de biomasa equivale a 5.43 % del peso original.

ASSOCIATION OF SERUM VITAMIN D AND KEY CO-NUTRIENTS IN RELATION TO HYPERTENSION: A CROSS-SECTIONAL STUDY BASED ON NHANES DATA

Observational studies demonstrate strong associations between deficient serum vitamin D (25(OH)D) levels and cardiovascular disease. To further examine the association between vitamin D and hypertension (HTN), data from the 2003-2006 National Health and Nutrition Examination Survey were analyzed to assess whether the association between vitamin D and HTN varies by sufficiency of key co-nutrients necessary for metabolic vitamin D reactions to occur. Logistic regression results demonstrate independent effect modification by calcium, magnesium, and vitamin A on the association between vitamin D and HTN. Among non-pregnant adults with adequate renal function, those with low levels of calcium, magnesium, and vitamin D levels had 1.75 times the odds of HTN compared to those with sufficient vitamin D levels (p = <0.0001). Additionally, participants with low levels of calcium, magnesium, vitamin A, and vitamin D had 5.43 times the odds of HTN compared to those with vitamin D sufficiency (p = 0.0103).

Reproductive performance as affected by lactation status and body fat in beef cows.

Seventy-one mature Brangus cows, 38 nonlactating (NL) and 33 in late stage of lactation (L) were fed for 192 days (Phase I) a low energy diet (L). During Phase II (65 days) 19 NL and 17 L cows were fed a high energy diet (H). The other nonlactating (19) and lactating (16) cows remained on the low energy diet. Energy restriction during Phase I did not affect (P> 0.05) cyclic ovarian activity although losses in body weight and condition were substantial. Rapid changes in body weight, condition, and percent empty body lipe (EBLP) during Phase II did not substantially influencefertility, although a five-fold difference in EBLP was observed (NL0H vs. L-L). Treatment groups did not differ (P> 0.05) in conception rate, days from the beginning of the breeding season to breeding and to conception, conception at first service, and number of services per conception. Values observed for these parameters for NL-H, L-H, NL-L, and L-L groups were respectively: 68,4%, `3,.2, 23.3, 36.8% and 1.68; 82,4% 12.7, 19.5, 58.8% and 1.29; 68.4%, 10.2, 17.4, 47.4%, and 1.41; 68.8%, 12.4, 19.5, 43.7%, and 1.50.

An exploration of treatment burden and patient capacity in people with stroke

Background and aims: Advances in modern medicine have led to improved outcomes after stroke, yet an increased treatment burden has been placed on patients. Treatment burden is the workload of health care for people with chronic illness and the impact that this has on functioning and well-being. Those with comorbidities are likely to be particularly burdened. Excessive treatment burden can negatively affect outcomes. Individuals are likely to differ in their ability to manage health problems and follow treatments, defined as patient capacity. The aim of this thesis was to explore the experience of treatment burden for people who have had a stroke and the factors that influence patient capacity. Methods: There were four phases of research. 1) A systematic review of the qualitative literature that explored the experience of treatment burden for those with stroke. Data were analysed using framework synthesis, underpinned by Normalisation Process Theory (NPT). 2) A cross-sectional study of 1,424,378 participants >18 years, demographically representative of the Scottish population. Binary logistic regression was used to analyse the relationship between stroke and the presence of comorbidities and prescribed medications. 3) Interviews with twenty-nine individuals with stroke, fifteen analysed by framework analysis underpinned by NPT and fourteen by thematic analysis. The experience of treatment burden was explored in depth along with factors that influence patient capacity. 4) Integration of findings in order to create a conceptual model of treatment burden and patient capacity in stroke. Results: Phase 1) A taxonomy of treatment burden in stroke was created. The following broad areas of treatment burden were identified: making sense of stroke management and planning care; interacting with others including health professionals, family and other stroke patients; enacting management strategies; and reflecting on management. Phase 2) 35,690 people (2.5%) had a diagnosis of stroke and of the 39 co-morbidities examined, 35 were significantly more common in those with stroke. The proportion of those with stroke that had >1 additional morbidities present (94.2%) was almost twice that of controls (48%) (odds ratio (OR) adjusted for age, gender and socioeconomic deprivation; 95% confidence interval: 5.18; 4.95-5.43) and 34.5% had 4-6 comorbidities compared to 7.2% of controls (8.59; 8.17-9.04). In the stroke group, 12.6% of people had a record of >11 repeat prescriptions compared to only 1.5% of the control group (OR adjusted for age, gender, deprivation and morbidity count: 15.84; 14.86-16.88). Phase 3) The taxonomy of treatment burden from Phase 1 was verified and expanded. Additionally, treatment burdens were identified as arising from either: the workload of healthcare; or the endurance of care deficiencies. A taxonomy of patient capacity was created. Six factors were identified that influence patient capacity: personal attributes and skills; physical and cognitive abilities; support network; financial status; life workload, and environment. A conceptual model of treatment burden was created. Healthcare workload and the presence of care deficiencies can influence and be influenced by patient capacity. The quality and configuration of health and social care services influences healthcare workload, care deficiencies and patient capacity. Conclusions: This thesis provides important insights into the considerable treatment burden experienced by people who have had a stroke and the factors that affect their capacity to manage health. Multimorbidity and polypharmacy are common in those with stroke and levels of these are high. Findings have important implications for the design of clinical guidelines and healthcare delivery, for example co-ordination of care should be improved, shared decision-making enhanced, and patients better supported following discharge from hospital.

Formulación de estrategias para incentivar el turismo sostenible en Colombia, con énfasis en regiones con un alto nivel de desarrollo económico.

Actualmente el sector turismo se ha ido posicionando como una de las principales fuentes de prosperidad (en términos de empleo, bienestar y riqueza) por encima de grandes industrias como la automotriz y la petrolera, lo cual, es considerado por las Naciones Unidas como una gran oportunidad de desarrollo para los países emergentes. Colombia, es un ejemplo de esta situación por su gran potencial en turismo naturaleza, el cual está comenzando a incluirse en planes de desarrollo turístico como en Villavicencio, actual epicentro comercial de los llanos orientales y líder en el desarrollo turístico del Meta. El trabajo pretende ser un estudio de caso que evidencie los factores que han impedido que el desarrollo sostenible progrese de forma paralela al crecimiento turístico que se está dando en la región, enfocado en los alojamientos urbanos y rurales de la capital del Meta. A partir de esto, se realiza una encuesta a 42 hoteles, una vez vistos los resultados está, se analiza la manera en que es asimilada la sostenibilidad desde un punto de vista práctico. La información recopilada revela que los agentes turísticos presentan carencia de concientización, respecto al movimiento “verde” que se está dando a nivel mundial, no tienen como prioridad los temas sostenibles, desconocen las normas ambientales y no tienen claridad sobre los procesos de certificación

Infección por virus sincitial respiratorio y su relación con valores de IGG en niños críticos

Antecedente: La infección por el virus sincitial respiratorio (VSR) representa una elevada morbimortalidad, y en algunos casos necesidad de manejo en unidades de cuidado intensivo pediátrico (UCIP). La respuesta inmunológica influye de manera directa en la expresión de la severidad y pronóstico de los pacientes con infección respiratoria. Metodología: Estudio de una cohorte retrospectiva de pacientes con infección respiratoria grave secundaria a VSR, sin historia de inmunodeficiencia, atendidos en la UCIP del Hospital Universitario Clínica San Rafael. Se realizó análisis descriptivoglobaly de acuerdo a la categorización de las prueba de IgG. Resultados: De 188 pacientes que ingresaron a la UCIP, 13% presentaron infección por VSR (24), con una edad promedio de 7,3 (DE=3,6) meses. Pertenecían al sexo masculino79,83%. Se encontró que 12,5% tenían un valor de IgGbajo para su edad, 58,33% tenían valores en límite inferior y el 29,17% dentro de rangos normales para su edad. En los pacientes con IgG baja, fue mayor la presentación de choque séptico que no responde a líquidos (100 vs 92 vs 86%), la mediana de días de ventilación mecánica fue mayor (8 vs 6 vs 5 respectivamente), así como la mortalidad (67 vs 7,1 vs 0%). Conclusión: Nuestra serie encontró que aquellos pacientes con niveles bajos o valores en el límite inferior de IgG sérica tuvieron mayor compromiso sistémico, mayor duración de ventilación mecánica y mayor mortalidad. Se necesitan estudios prospectivos que relaciones niveles bajos de IgG con severidad y pronostico en estos pacientes con infección grave por VSR.

Entre el terrorismo y el terrorismo en red, un debate a propósito de los lobos solitarios en Estados Unidos (2001-2014)

El interés de esta disertación es otorgar una respuesta a la fenomenología del Lobo Solitario, que se alza como amenaza frente a los Estados, y es necesaria su correcta comprensión para poder contrarrestar sus efectos sobre la sociedad. De esta manera, se propone un debate entre los conceptos de terrorismo expuesto por un lado por Bruce Hoffman, y por el otro por Luis de la Corte Ibáñez, quienes aportarán herramientas de análisis para lograr entender la fenomenología. Para terminar proponiendo la teoría de redes, expuesta por Arquilla y Ronfeldt y Charles Perrow, como mecanismo de solución a la brecha conceptual existente, definiendo a los lobos solitarios a nivel operacional como nodos sin red, y a nivel de adoctrinamiento como redes de débil acople.

Study of heterostructures of Cu3BiS3–buffer layer measured by Kelvin probe force microscopy measurements (KPFM)

The interface formed between Cu3BiS3 thin films and the buffer layer is a potentially limiting factor to the performance of solar cells based on Al/Cu3BiS3/buffer heterojunctions. The buffer layers of ZnS and In2S3 were grown by coevaporation, and tested as an alternative to the traditional CdS deposited by chemical bath deposition. From the Kelvin probe force microscopy measurements, we found the values of the work function of ZnS, In2S3, and CdS, layers deposited into Cu3BiS3. Additionally, different electronic activity was found for different grain boundaries (GBs), from studies under illumination, we also found the net doping concentration and the density of charged GB states for Cu3BiS3 and Cu3BiS3/CdS.

Sexual Activity of Indigenenous Ram Base on Ear Type

Research was conducted to know of sexual activity of indigeneous ram in experimental station, Animal Research Institute, Ciawi-Bogor. Twelve ram were roundly mated with two ewes for fiveteen minutes. All ram were allocated into two groups base on ear type (long and short). The variable observed were time of climbing, time and sum of ejaculation interval with time of climbing, and mating efficiency. Data analyses were used t test. The result of analyses showed that first time of ejaculation in ram of long ear type (4,92 ± 2,61 m) was longer than short ear type (1 ± 0,68 minute) (P<0,01). Sum of ejaculation in long ear type (1,33 ± 0,81 time) was leaster than short ear type (3 ± 1,09 time) (P<0,05). Ejaculation interval with to follow climbing in long ear type (5,43 ± 3,23 minute) was longer than short ear type (2,29 ± 1,76 minute) (P<0,05). Mating efficiency showed that highly significantly (P<0,01). In ram of short ear type (3,6 time) was more efficient than ram of long ear type (1,38 time). The first time of climbing, sum of climbing, and ejaculation interval were has not significantly (P>0,05). It was concluded that the mating rate in indigeneous ram of short ear type was higher than long ear type.
