El profesorado universitario ante la e-evaluación del aprendizaje
El artículo se enmarca en el campo de la eevaluación
en la Universidad. Se pretende identificar
cómo se gestiona el proceso de evaluación de los estudiantes
y, a la vez, conocer la actitud de los docentes
universitarios hacia la incorporación de las tecnologías
en el proceso de evaluación de aprendizajes. La metodología
descriptiva-correlacional empleada se basa en
la aplicación de una encuesta electrónica a una muestra
representativa por rama y categoría profesional de
docentes en la Universidad de Salamanca. Los resultados
obtenidos, tras la realización de los contrastes inferenciales
oportunos de “actitud” por rama de conocimiento,
categoría profesional y años de docencia,
muestran diferencias estadísticamente significativas
por rama de conocimiento
STANDARDIZED CATCH RATES OF ALBACORE (THUNNUS ALALUNGA BONNATERRE, 1788) IN THE SPANISH SURFACE LONGLINE FISHERY IN THE WESTERN MEDITERRANEAN IN THE PERIOD 2009-2019
Standardized relative abundance indices of albacore (Thunnus alalunga Bonnaterre, 1788)
caught by the Spanish surface longline (LLALB) in the western Mediterranean Sea were
estimated for the period 2009-2019. Yearly standardized CPUE were estimated through
Generalized Linear Mixed Effects Models (GLMM) under a negative binomial error
distribution assumption. The main factors in the standardization analysis were year and season
(quarter). The index shows an increasing trend from the beginning of the series (2009) to a
maximum in 2011; following a decrease up to 2013, and a relatively stable trend fluctuating
around a level three and a half times lower compared to the maximum abundance for the period
2013-2019.En prens
Autoridad y sentido del humor en la educación familiar
Desde la perspectiva antropológica suscrita en esta monografía el sentido del humor es
un soporte emocional para la felicidad y una disposición afectiva para la alegría, y por lo
tanto expresión natural de dicha virtud. Esto lo hace dependiente la buena orientación
de la inteligencia y la voluntad. En la educación familiar dicha orientación se traduce -
en buena parte- en la adecuada armonización entre afecto y autoridad, un reto que
puede ser facilitado a través del sentido del humor. Como mecanismo natural de
liberación no traumática de las emociones negativas, permite autorregular la propia
dinámica afectiva, promoviendo así competencias emocionales parentales en cuanto a
flexibilidad, mantenimiento de la serenidad, asertividad en la comunicación. Todo lo cual
contribuye a un equilibrado ejercicio de la autoridad parental.From the anthropological perspective endorsed in this monograph sense of humour acts
as an emotional foundation for happiness and is a mood disposition for joy that naturally
expresses the latter. This makes it dependant on the correct exercise of intelligence and
willpower. In the context of family education this ability requires, among others, an
adequate adjustment between parental authority and affection, a challenge that can be
eased by sense of humour. Since it is a natural mechanism of non-traumatic release
from negative emotions, it allows to self-regulate one’s psychological dynamics through
enhancing the emotional competences necessary to maintain serenity, to communicate
more assertively and to behave with more flexibility. All of which contributes to a
balanced exercise of parental authority
Standardized catch rates for Mediterranean swordfish (Xiphias gladius Linnaeus, 1758) from the Spanish longline fishery. 1988-2017.
Standardized relative abundance indices for swordfish (Xiphias gladius Linnaeus, 1758) caught
by the Spanish surface longline in the western Mediterranean Sea were estimated for the period
1988-2017. Standardized CPUEs were estimated through a General Linear Mixed Modeling
(GLMM) approach under a negative binomial (NB) error distribution assumption. The main
factors in the standardization analysis were fishing area and time of the year (quarter). The
standardized index showed notable annual fluctuations without any definite trend for the period
under study
STANDARDIZED CATCH RATES FOR MEDITERRANEAN SWORDFISH (XIPHIAS GLADIUS LINNAEUS, 1758) FROM THE SPANISH LONGLINE FISHERY. 1988-2018
Standardized relative abundance indices for swordfish (Xiphias gladius Linnaeus, 1758) caught
by the Spanish surface longline in the western Mediterranean Sea were estimated for the period
1988-2018. Standardized CPUEs in number were estimated through a General Linear Mixed
Modeling (GLMM) approach under a negative binomial (NB) error distribution assumption.
Standardized CPUEs in biomass were estimated through a General Linear Mixed Modeling
(GLMM) approach under a log-normal error distribution assumption. The main factors in the
standardization analysis were fishing area and time of the year (quarter). The standardized
indices showed notable annual fluctuations without any definite trend for the period under studyEn prens
STANDARDIZED CATCH RATES OF ALBACORE (THUNNUS ALALUNGA BONNATERRE, 1788) IN THE SPANISH RECREATIONAL FISHERY IN THE WESTERN MEDITERRARREAN IN THE PERIOD 2005-2019
Catch and effort data from the Spanish recreational fishery in the Balearic Sea (Western
Mediterranean) were analysed to estimate an index of relative abundance for albacore for the
years 2005-2019. Standardized catch per unit effort (CPUE) in number were estimated through
a General Linear Mixed Modeling (GLMM) approach under a negative binomial (NB) error
distribution assumption. Nominal catch rates and a standardized abundance index are
presented along with estimates of 95% confidence limits of the predicted means. These indices
show an upward trend from the start of the series 2005 peaking in 2013; followed by a decrease
until 2015. For the latest four-year period (2016-2019), the index shows a relatively stable
trend fluctuating around a level two times lower than the maximum abundance recorded in the
time series.En prens
Information and community for mothers on the Internet: An analysis of the principal Spanish baby websites
The four baby websites with most users in Spain (www.mibebeyyo.com, www.bebesymas.com, www.parabebes.com and www.elbebe.com) are at the centre of the present study. The sites have been analysed from the perspective of the social web, or Web 2.0, focusing on their structure and content throughout one year (from October 2010 to October 2011), as well as on their presence on Facebook and Twitter. Also, user preferences and the levels of user activity and participation were studied. The purpose was to determine how the potential of Web 2.0 is materialised in the very concrete segment of the population that is the target of the websites, mothers and mothers-to-be.---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------El análisis de las cuatro webs de bebés con mayor audiencia en España (www.mibebeyyo.com, www.bebesymas.com, www.parabebes.com y www.elbebe.com) centra la presente investigación.

Biological aspects of little tunny Euthynnus alletteratus from Spanish and Portuguese waters.
This study provides information on some biological aspects of Euthynnus alletteratus from the
western Mediterranean (Spanish coast) and in the Atlantic Ocean (south of Iberian Peninsula).
A total of 1266 individuals were measured between 2003 and 2017. The L-W relationship was
calculated with W equal to 0.01242 FL3.058
. Histological analysis of the ovaries and the monthly
variation of the gonadosomatic index for both sexes suggested that the spawning season for
Euthynnus alletteratus in the western Mediterranean Sea takes place from June to August. The
lengths at first maturity (L50) were estimated to be 50.1 cm and 43.4 cm FL for female and
male, respectively. Age at first maturity (A50) was calculated
EFFECTS OF ICCAT Rec [2016-05] SIZE REGULATION ON THE DISCARDS OF THE SPANISH LONGLINE FISHERY TARGETING SWORDFISH (Xiphias gladius Linnaeus, 1758) IN THE WESTERN MEDITERRANEA
The ICCAT Commission, at its meeting on November 2016, approved a multi-annual recovery
plan for the Mediterranean swordfish starting in 2017 and continuing through 2031 (ICCAT Rec
[2016-05]). Among other provisions, the recovery plan proscribed a minimum landing size (MLS)
of 100 cm (lower-jaw fork length- LJFL), which is 10 cm higher than the previously implemented
(ICCAT Rec [2013-04]). The aim of this study is to assess the effect of the recently implemented
MLS on the swordfish discarding activities by the Spanish surface longline fishery operating in
the western Mediterranean for the period 2015-2017. Our results show that: i) as compared to
the former MLS (ICCAT Rec [2013-04]), a higher percentage of undersized dead fish is now
discarded at sea, with the additional risk that does not be reported and taken into consideration
during the assessment of the stock; ii) the amount of fishing effort (number of hooks) for fulfilling
the allocated quota has increased; iii) the fishing season must be longer to achieve the allocated
quota. Both the increase in fishing effort and the lengthening of the fishing season have an
adverse effect on the economic profitability of the surface longline fleet without achieving the
intended reduction in the fishing mortality exerted on the juvenile fraction of the Mediterranean
swordfish stock
Macroscopic and microscopic maturity stages. living working document for small tuna species.
Maturity ogives are usually estimated using different methods, including macroscopical and
microscopical maturity data. Differences in maturity ogives estimations are found for species and
by area/stock. So those differences may be a consequence of the use of different methodological
techniques (criteria) or due to different spawning tactics. Taking this into account is essential to
guarantee that the maturity criteria for each species are consistent across the laboratories and
countries involved in stock assessment. The objective of this document is to show a large amount
of detailed photos (macro and microphotographs) of the different gonad stages of Auxis rochei,
Sarda sarda and Euthynnus alletteratus, for females and males, which will be an enhancement to
the descriptions of maturity stages given in the maturity tables
