Errores de consistencia en los valores p informados en las revistas españolas de PsicologĂa
Recent reviews have drawn attention to frequent consistency errors when reporting statistical results. Method: We have reviewed the statistical results reported in 186 articles published in four Spanish psychology journals. Of these articles, 102 contained at least one of the statistics selected for our study: Fisher-F, Student-t and Pearson-Ï2. Results: Out of the 1,212 complete statistics reviewed, 12.2% presented a
consistency error, meaning that the reported p-value did not correspond to the reported value of the statistic and its degrees of freedom. In 2.3% of the cases, the correct calculation would have led to a different conclusion than the reported one. In terms of articles, 48% included at least one consistency error, and 17.6% would have to change at least one conclusion. In metaanalytical terms, with a focus on effect size, consistency errors can be considered substantial in 9.5% of the cases. Conclusion: These results
imply a need to improve the quality and precision with which statistical results are reported in Spanish psychology journalsRecientes trabajos han llamado la atenciĂłn sobre la presencia de frecuentes errores de consistencia al informar de los resultados estadĂsticos. MĂ©todo: hemos revisado los resultados estadĂsticos de 186 artĂculos publicados en cuatro revistas españolas de PsicologĂa, 102 de los cuales contenĂan alguno de los
estadĂsticos seleccionados para nuestro estudio: F de Fisher, t de Student y Ï2 de Pearson. Resultados: de los 1.212 contrastes completos revisados el 12,2% presenta algĂșn tipo de error de consistencia: el valor p informado no se corresponde con el valor del estadĂstico de contraste y sus grados de libertad. En el 2,3% de los casos el error detectado conllevarĂa un cambio en la conclusiĂłn estadĂstica del contraste. En tĂ©rminos del nĂșmero de artĂculos, el 48% de los revisados incluye algĂșn error de consistencia y al menos el 17,6% tendrĂa que cambiar alguna de sus conclusiones. En tĂ©rminos meta analĂticos, los errores de consistencia pueden considerarse importantes en el 9,5% de los casos. Conclusiones: estos resultados señalan la necesidad de mejorar la calidad y precisiĂłn con la que se informa de los resultados estadĂsticos en las revistas españolas de PsicologĂ
A use-side trade margins matrix for the Andalusian economy
According to the National Accounting Systems proposed by United Nations (1993) and Eurostat (1996), use and make (or supply) matrices should be measured before goods and services are conveyed to the markets (basic values). Actually, the make table is defined in basic values (excluding trade and transport margins and net commodity taxes) whereas the use table is in purchasers' values (including them). This paper shows how these margins and taxes can be removed from the use table with the purpose of entering both of them in the so-called material balance equation. With respect to trade margins, our approach is based on the use-side procedure from the ESA-95 Input-Output Manual (Eurostat, 2002) and is also being applied to the forthcoming 2000 Andalusian Input-Output Framework.Input-output analysis, use and make matrices, trade margins, National Accounts
El proemio de la "OlĂmpica VII" de PĂndaro o sobre los problemas de la traducciĂłn de la lĂrica
Los problemas que la traducciĂłn de todo texto entraña, en la medida en que implica que un determinado mensaje sea transferido de un cĂłdigo lingĂŒĂstico a otro diferente, y a los derivados de ser un texto perteneciente a una cultura diferente de la nuestra, se añaden los especĂficos de la traducciĂłn de la poesĂa. Sin soslayar las dificultades que la versiĂłn de cualquier texto griego al español plantea, nos fijaremos especialmente en aquellas que conciernen a las diferencias antropolĂłgicas y culturales.The problems from the translation of a text arise from the fact that a particular message is transferred from one language to a different code. To this we must add the problems of translating a text from another culture, even more if it comes from poetry. Without ignoring the difficulties that the Spanish version of any Greek text raises, we look especially those concerning the anthropological and cultural differences
Cambio en el centro de la distribuciĂłn y en las puntuaciones individuales: relaciĂłn con distribuciones heteroscedasticas pre y post prueba
Background: Although average-based effect size (ES) and percentage of individual changes (PIC) are quite different, they are not independent: larger ESs lead to higher PICs. However, this association has not been sufficiently explored. Method: We analyzed this association based on data simulated in the context of a pre-post design, with and without control groups. We simulated various distributions, sample sizes, degrees of test-retest reliability, effect sizes, and different variances in pre-and post-test. Results: The PIC is closely associated with the ES across a wide variety of empirically frequent scenarios. In the âsingle group pre-post designsâ, the linear regression model shows R2 values above 0.90. In the âcontrol group pre-post designsâ, the linear regression model shows R2 values above 0.80. These results were found even when the post-test variability differed from that of the pre-test, replicating, extending and generalizing the findings in previous studies. Conclusions: (1) In the absence of information about the PIC, the ES may be used to estimate this percentage. (2) The PIC is useful in interpreting the meaning of ES measures.Antecedentes: aunque el tamaño del efecto (ES) y el porcentaje
de cambios individuales (PIC) son cosas distintas, no parecen ser
independientes: mayores ESs conllevan mayores PICs. Pero esta relaciĂłn
todavĂa no ha sido sufi cientemente explorada. MĂ©todo: estudiamos dicha
relación mediante datos simulados en el contexto de un diseño pre-post
con y sin grupo control. En la simulaciĂłn se han utilizado diferentes
distribuciones, tamaños muestrales, niveles de fiabilidad test-retest,
efectos de varios tamaños y distintas variabilidades en el pre- y en el
post-test. Resultados: el PIC estĂĄ estrechamente relacionado con el ES.
En los diseños pre-post, el modelo de regresión lineal ofrece valores R2
por encima de 0,90. En los diseños pre-post con grupo control, valores
R2 por encima de 0,80. Estos resultados se mantienen incluso cuando la
variabilidad del post-test es distinta de la del pre-test. Conclusiones: (1)
cuando no se tiene información sobre el PIC, el tamaño del efecto puede
utilizarse para estimar ese porcentaje; (2) el PIC sirve para precisar el
significado de las medidas del tamaño del efectoThis study was funded by the research project PSI2015-67286-P

Paleopopulations and ecological connectivity in the Natura 2000 Network: proposal for the serpentineâsoil Spanish firs of Sierra Bermeja (SerranĂa de Ronda)

tional Programme in Andalusia (EU regional programme): ForestMed
(A-RNM-688-UGR20).One of the conservation priorities of the Natura 2000 Network is the ecological connectivity of forests and species of com-
munity interest to facilitate compliance with the obligations of the EU Habitats Directive. The location of paleo-populations
and past distribution areas is a first step towards creating an ecological corridor which, with the protection enjoyed by
Special Areas of Conservation, could positively impact the resilience of forest species in the face of Climate Change. The
endangered relict forests of Spanish fir (Abies pinsapo) are endemic in the SerranĂa de Ronda (Baetic Cordillera, Southern
Spain) and form a highly fragmented habitat of community interest. Amongst these forests, the Spanish fir forests that grow
on serpentine soils are particularly interesting. This ultramafic mountain range has suffered the highest recurrence of forest
fires in all the SerranĂa de Ronda, and as a result, the Spanish fir forests have been subject to processes of local extinction
throughout history. In this research, we used pedoanthracology to uncover ancient locations of Abies pinsapo; in this way,
forest fires are the main cause of the disappearance of this emblematic species in Sierra Bermeja, and their charcoal remains
allowed us to make a precise reconstruction of its past distribution area. On the basis of the data obtained, an ecological
corridor linking these relict forests was proposed. This corridor has now begun to be implemented with the participation of
public and private social agents.Universidad de Granada/CBUASpanish Ministry of Education, Culture and Sports (Ministerio de Educacion, Cultura y Deportes del Gobierno de Espana)

(Spanish fir) in the SerranĂa
de Ronda region, southern Spain, during the Holocene. The main method was pedoanthracological analysis, the study of
non-archaeological charcoal found in natural soils. In this research a total of 37 soil excavations were done in several mountain
ranges with potentially favourable places for firs to have grown in the past. Specific sites and places such as hillsides,
endorheic basins (with no outflow), sinkholes, summits and mountain passes were selected on the basis of evidence from a
range of different sources including ancient documents, pollen studies and species distribution models. The soil samples collected
from these sites were prepared in the laboratory and the charcoal was identified and radiocarbon dated. Statistical and
cartographic analyses were also done. The study revealed evidence of past populations of Abies sp. in places where it is no
longer found today. A total of 47 different chronologies were obtained from these sites with ages ranging between 9,931 cal bp
and 78 cal bp. In addition, the wide variations in the charcoal values enabled us to make an initial estimate of the importance
of ancient forest fires in different places in the SerranĂa de Ronda. When this information has been considered with all the
other available data sources, it will be an essential resource for the efficient management of relict fir woods in southern Spain.Ministerio de Educacion del Gobierno de Espana (Ministry of Education of the Government of Spain) 18/03023dependents on the Ministerio de Economia y Competitividad del Gobierno de Espana y la Junta de Andalucia (Ministry of the Economy) CSO2017-83576-P

Purification and characterization of a hygromycin B phosphotransferase from Streptomyces hygroscopicus
4 pages, 4 figures, 1 table, 20 references.A hygromycin B phosphotransferase activity from Streptomyces hygroscopicus has been highly purified by ammonium sulphate fractionation followed by affinity column chromatography through Sepharose-6B- hygromycin-B.The combined active fractions showed a singleprotein band (41 kDa) when subjected to polyacryl- amide gel electrophoresis in the presence of sodium dodecyl sulphate. When gel electrophoresis was performed under non-denaturing conditions, the single protein band promoted in situ phosphorylation of hygromycin B, indicating that this protein corresponded to the purified hygromycin B phosphotransferase. The enzyme has been purified 236-fold and approximate Km values of 0.56 pM and 36.4 pM for hygromycin B and ATP, respectively, were deduced.This research was supported by grants from the ComisiĂłn Asesora de InvestigaciĂłn CientĂfica y TĂ©cnica (6131165 and 497) and by an institutional grant from the Fondo de Investigaciones Sanitarias to the Centro de BiologĂa Molecular.

Transcranial ultrasound simulation with uncertainty estimation
Transcranial ultrasound simulations are increasingly used to predict in situ exposure parameters for ultrasound therapies in the brain. However, there can be considerable uncertainty in estimating the acoustic medium properties of the skull and brain from computed tomography (CT) images. This paper shows how the resulting uncertainty in the simulated acoustic field can be predicted in a computationally efficient way using linear uncertainty propagation. Results for a representative transcranial simulation using a focused bowl transducer at 500âkHz show good agreement with unbiased uncertainty estimates obtained using Monte Carlo
