    Beschreibung: In Colombia, as in other Latin American countries, educational reforms are being carried out with the aim of promoting quality education. Thus, current psychology programs undergo from time to time an evaluation and rethinking of their curricula, content, methods, assessment practices and other aspects in order to improve, redefine and contextualize psychology education. Thus, this book invites us to reflect on how, why and for what purpose to train psychologists today in Colombia and how research training provides spaces for reflection to think about new perspectives and approaches to the social challenges of our country. Moreover, the curriculum, as a reiterative school practice, ends up producing and reproducing unsuspected subjective forms according to the demands of a society, thus producing particular ways of acting and thinking that, among other aspects, are alienating. The proposal, then, is to identify this situation in order to transcend a merely technical curriculum and reproducer of social practices and bet on an emancipating curriculum, autonomizing the subjects and transforming the practices of a social group. Hence, questioning and debating the training in psychology is central both for the discipline and for the context.

    Beschreibung: En Colombia como otros países latinoamericanos, se llevan a cabo reformas educativas con el fin de apostarle a una educación de calidad. Así, los programas en psicología actuales cada tanto tiempo someten a evaluación y replanteamiento su currículo, contenidos, métodos, prácticas evaluativas y demás aspectos con el fin de mejorar, redefinir y contextualizar la formación en psicología. Así, el presente libro invita a reflexionar acerca de cómo, por qué y para qué formar psicólogos hoy en Colombia y de qué manera la formación en investigación propicia espacios de reflexión para pensar nuevas miradas y apuestas ante los desafíos sociales de nuestro país. Además, el currículo en cuanto práctica escolar reiterativa, termina produciendo y reproduciendo insospechadamente formas subjetivas acordes con las demandas de una sociedad, produciendo así formas particulares de actuar y de pensar que, entre otros aspectos, son alienantes. La propuesta estribaría, entonces, en identificar dicha situación para trascender un currículo meramente técnico y reproductor de prácticas sociales y apostar por un currículo emancipador, autonomizador de los sujetos y transformador de las prácticas de un grupo social. De ahí que preguntarse y debatir la formación en psicología resulta central tanto para la disciplina como para el contexto.

    Notizen: We have studied GaxIn1−xAsySb1−y/GaSb heterostructures for x=0.84 and y=0.14 using the photoacoustic technique with the heat transmission configuration. A theoretical model, which includes all the possible nonradiative recombination mechanisms that contribute to heat generation, was developed to calculate the photoacoustic signal for this type of heterostructure. The Auger recombination lifetime τAuger was determined by fitting our experimental results to the calculated frequency dependence of the theoretical photoacoustic signal. The obtained value for τAuger is compatible with those reported in the literature for semiconductors with band-gap energies below and above 0.5 eV, the energy region where there is a lack of experimental τAuger values. © 2001 American Institute of Physics.

    Notizen: The age, growth and reproduction of Leuciscus pyrenaicus (Günther, 1868), an endemic cyprinid from the Iberian Peninsula, was studied from November 1987 to September 1989 in a small seasonal tributary of the Guadalquivir river basin. Maximum fork lengths observed were a 160 mm male with six scale annuli and a 171 mm female aged 7 +. Maximum ages observed were 7 + in males and 8 + in females. There were no significant differences in the annual growth increments between sexes. Seasonal growth period started in March and continued for 5 to 6 months. Mean lengths of 1 + specimens onwards diminished during summer and/or autumn. Males and females matured in their third and fourth year of life respectively. The overall sex ratio (272 males: 310 females) differed significantly from equality. Spawning began in May and ended in July. L. pyrenaicus is a multiple spawner that releases a minimum of two batches of eggs per female each year. Eggs in each batch were similar in both size (egg diameter) and number released. The relationship between fecundity (Fee) and fork length (mm) was represented by the formula: Fec=1.96 10−3 L2.50.

    Notizen: The interaction between the two components of a relativistic binary gas is investigated. Starting from the relativistic Boltzmann equation, general expressions for the rate of energy exchange, the relaxation time, and the coefficient of bulk viscosity are obtained. As a particular example, the formalism is applied to the study of a gas at very high temperatures, T〈∼6×109 °K, assuming that the energy exchange between matter and radiation is caused by Compton scattering; relativistic effects are fully taken into account.

    Notizen: The energy transfer between matter and radiation at very high temperatures is investigated. A previously presented formalism is applied to a mixture of electrons, positrons, and photons interacting through Compton scattering and pair creation and annihilation. The relaxation time toward thermal equilibrium and the bulk viscosity of the mixture are derived, and numerical results are presented for temperatures 3×108 K≤T≤1011 K. For temperatures T(approximately-greater-than)8×108 K pair creation and annihilation is found to be more efficient than Compton scattering in transferring energy between matter and radiation.

    Notizen: SUMMARY. 1. Age, growth and reproduction in an Atlantic population of the small fish, Aphanius iberus (Cuv. & Val., 1846), from the estuary of the Guadalquivir river were studied.2. The growth period was from April to September and the annulus on the scales was formed in April.3. The life-span was short with a winter age-structure of 95.9% 0+ fish, 3.9% 1+ and 0.2% 2+.4. The fecundity of this stock, before the beginning of reproduction, is represented by the formula: Fec=0.907 TL (cm)4.099. During the reproductive period 1+ females contained more, smaller eggs g−1 of gonad than 0+ fish.5. Males matured before females, but females were larger than males. The overall sex ratio did not differ from 1:1 but males dominated significantly during most of the spawning period.6. Aphanius iberus spawned intermittently during the reproductive period. From April to July, 1+ group specimens (7–12 months old) reproduced. Their offspring (0+ group; 3–4 months old) reproduced from July to September. Very few of the 1+ group specimens survived to spawn the following year.7. Mean gonadosomatic indices were much higher in the 1+ group than in the 0+ group and in females compared to males.8. The loss of condition and the disappearance of the 1 + group during spawning, may indicate the cost of a prolonged high level of reproductive effort.9. In this productive environment, the life history of Aphanius iberus is similar to that of Gambusia affinis (Baird & Girard, 1853) and Fundulus heteroclitus (Linnaeus) found in the same area.

    Notizen: The present paper assesses the fertilization and hatching rates of an artificial fertilization series (n=1153) using fresh and cryopreserved sperm from 49 specimens of turbot Scophthalmus maximus (L.), carried out to confirm the results of a previous study, with the ultimate aim of transferring these cryo-preservation techniques to commercial hatcheries. No significant differences were found between the fertilization rates of the two groups (fresh and cryopreserved sperm) when their respective fertility rates were 〉69.2%, which was the case in 75% of all fertilizations. Likewise, no significant differences in hatching rates were found. In order to use the cryopreserved sperm more efficiently, a key concern for commercial use of this technique, we also experimented with a lower sperm:diluent ratio (1:1) than used previously at our centre. We also compared the traditional 0.5-mL straws with 2-mL cryotubes able to contain a higher volume of sperm, finding no significant differences in the resulting fertilization and hatching rates. In conclusion, the use of cryopreservation for turbot sperm presents major advantages for broodstock management in commercial hatcheries.

    Notizen: The age, growth and reproduction of Chondrostoma polylepis willkommi, an endemic cyprinid from the Iberian Peninsula, was studied for 2 years in a seasonal stream in the Guadalquivir River basin. Annual growth was low. Maximum ages observed were 5+ in males and 7+ in females. There was no significant difference in growth between sexes. Seasonal growth period started in May and continued for 2 to 6 months depending on age. The mean lengths of 1 + and 2+ age-groups decreased once the growth period had finished, probably related to reproductive stress and adverse ecological conditions, and this could explain the occurrence of Rosa Lee's phenomenon. Both sexes matured at the end of their second year of life (1+). There was a significant difference from 1: 1 in the overall sex ratio of 334 males to 464 females. Reproductive period started in March and lasted until May. Ch. p. willkommi was a multiple spawner that released two batches of eggs per female each year. The regression between fecundity (F) and fork length (l., mm) was: F=6.20 103 L.2.78. In females from age 2 + onwards, relative annual investment in somatic growth and reproduction was equivalent, implying that the same energy was allocated to reproduction as to maintenance/growth. Compared with other Ch. polylepis populations, the life-history patterns of this population, located in a small and seasonal stream in a southern latitude, were characterized by a low annual growth, a trade-off between reproduction and growth/maintenance, early maturity, low number of age-groups and high fecundity from multiple spawnings.

    Notizen: A total of 1068 eels were examined from a population located in the Guadalquivir river estuary (37°N, 6°25′W). Maximum ages recorded were 4 + (males) and 7+ (females), and maximum lengths were 39-1 cm (males) and 54.1 cm (females). No growth was recorded between November and April, most occurring in May and, to a lesser extent, in June-October. Females grew to be larger than males. A classification analysis, based on 17 different European eel populations revealed that populations in brackish waters grew faster than those in fresh waters, but latitude also had an influence. Length-weight relationships obtained for three eel categories (males, females and undifferentiated) were used to estimate relative condition: condition cycles were similar between sexes, with increases in autumn and decreases in winter. There were monthly fluctuations in the sex ratio, and females dominated significantly in the combined catch (234 males/276 females).
