Estudio morfológico y taxonómico de los ampulláridos de la República Argentina: Maria Isabel Hylton Scott. [tomado de la Revista del Museo Argentino de Ciencias Naturales “Bernardino Rivadavia”, Ciencias Zoologicas, Tomo III, nº 5, 1957.]

Corría 1968. Yo era un estudiante enamorado de las ampularias, y alguien me regaló una separata del trabajo de María Isabel Hylton Scott titulado “Estudio morfológico y taxonómico de los ampulláridos de la República Argentina”. Hoy soy un profesor e investigador jubilado, … enamorado de las ampularias ¿Qué pasó en el medio? Por diversas circunstancias de mi vida comencé mi carrera estudiando roedores. Pero como canta un tango, “siempre se vuelve al primer amor” y dos décadas después (hacia 1990) conseguí algo de financiación para estudiar uno de estos extraordinarios animales: Pomacea canaliculata. Esto fue para m�� un nuevo comienzo: poco a poco fui dejando mis estudios en ratones silvestres, y formando un grupo dedicado a esta ampularia ¡Fue un cambio de phylum! Pecado difícilmente perdonable en un ambiente científico cada vez m��s competitivo, pero que me llenó de satisfacción, por lo que me felicito de haberlo cometido. Desde entonces he dirigido a siete doctorandos en distintos aspectos de la morfología y la ecofisiología de este animal (Albrecht, 1998; Vega, 2005; Gamarra-Luques, 2007; Koch, 2008; Giraud-Billoud, 2009; Cueto, 2011; Giraud-Billoud, 2011), y sus tesis tienen al menos dos cosas en com��n: P. canaliculata casi siempre en el título, y el trabajo de Hylton Scott (1957) siempre citado en la bibliografía. Ella, “la doctora”, la “decana de los zoólogos argentinos” (como escribió Cazzaniga, 1991) fue para nosotros, atrevidos que no la conocimos personalmente, a quien llam��bamos por sobrenombre “Doña Marisa”, y lo seguimos haciendo. Lo sigo haciendo yo, porque aunque jubilado “en los papeles”, sigo trabajando detrás de sus pasos. Hoy tengo un doctorando (C. Rodríguez) trabajando en P. canaliculata , el octavo de mis tesistas en esta especie, y deseo que no sea el último. Una revisión de la biología de ampuláridos actualmente en prensa en Malacologia (Hayes et al., 2015) cita repetidas veces el trabajo que hoy reedita ProBiota. Los autores provienen de un amplio “mundo”, porque “el mundo” de los ampuláridos se ha extendido antropocóricamente a lo que hoy es Estados Unidos, Europa, China y Japón. Esto no lo podría haber soñado Doña Marisa cuando comenzó sus pacientes estudios de la embriología de P. canaliculata hace ochenta años (Hylton Scott, 1934). Y si algún cientómetra quisiera calcular la vida media de sus citas, se encontraría con algo sorprendente: que la curva temporal de éstas no va decayendo ¡sino creciendo! Hoy no puedo imaginarme a m�� mismo, como investigador, si no me hubiera topado con esa separata de cien páginas, escritas en un castellano elegante y hoy amarillentas, a las que guardo como un tesoro (porque las que usamos son sus fotocopias). Por eso, al acercarse los 25 años de la muerte de esta gran cordobesa (y platense por adopción) le propuse a mi amigo Hugo L. López esta reedición, que el aceptó con entusiasmo. Y también le propuse a mi alumno G. I. Prieto, excelente dibujante, que le diera nueva vida a una vieja foto de Doña Marisa que fue publicada por Cazzaniga (1992). Los que conocieron a “la doctora” personalmente, podrán decir si Prieto logró revivir su penetrante mirada. Creo que sí. Alfredo Castro-Vazquez

Contribución al estudio biológico de Loligo brasiliensis Bl

A total of 592 individuals of Loligo brasiliensis from the Mar del Plata coastal fishing area (Buenos Aires prov., Argentina) have been studied during the 1961-1964 period. From a morphological point of view the population appears to be uniform and homogeneus. A brief description of this species is given in this paper since references in the literature are scarce from the time at which Blainville (1923) first described it. The only further references are found in D'Orbigny (1835), and Ferrusac (1839), and in Hoyle (1886), and Tyron Pilsbry (1879). In this paper the species was mentioned only as a bibliographical reference on morphological or biological conditions has been found in the literature. The distribution of this species ranges from Cuba, Brazil, Uruguay to the Argentine coast, probably down to the Gulf of San Jorge. The samples had been studied with respect to various body measurements by classifing the individuals in total length classes, since body length was considered the most significant measurement. The condition factor K has been calculated for different sexes and ages, for the various length classes. The results lead to the conclusion that the smaller the length the higher is the value obtained for K and viceversa. This is due to the fact that the length of the tentacle increases considerably with increasing size. Since the tentacle are quite light the factor K diminishes accordingly. The condition factor increases considerably from December to April with an average of 0.42, decrease and becomes stable from March to October, with an average of 0.30. This is a consequence of the ripening of the sex glands. The sex-ratios are as following: year 1961, 42 % female, 42 % male; year 1962, 51 % female, 45 % male; year 1963, 46 % female, 53 % male; year 1964, 26 % female, 42 % male, 32 % indif. The great percentage of 72 undifferentiated young individuals in the 1964 (March) sampling increases the ratio of undifferentiation. A short morphological description of both ovules and spermatozoos is given. An examination of the sex glands leads to the following conclusions: a) male and female sex gland in a preparatory stage during the whole year; b) the highest percentage of ripe glands is found through, November-March; e) the spawning appears to precede rather slowly, but this certain since the spawning environment does not coincide with the natural habitat of the species. Few spawning individuals were found; d) sexual differentiation begins at body lenght from 30 to 40 mm; i.e. a total length of approximately 145 mm. At a body length of 70 mm. the hectocotilication (sexual character) begins to appear. In June 1962, a sample gathered at Rawson (Chubut) was analyzed. The conclusion was reached that the sex glands in this population are in an earlier stage of development in comparison with those from the Mar del Plata area. Also the average for the factor K which were found to be 0.17 for females and 0.19 for male, are rather low for that date. These physiological facts are possibly related to morphological differences which will be pointed out in a forthcoming publication. Some very typical associations with Artemesia longinaris and Percophis brasiliensis were found. Cannibalism has been observed.

Prestaciones ocupacionales/laborales para personas con enfermedad mental. Estudio comparativo por CCAA

El estigma y la discriminación que sufren las personas con enfermedad mental y discapacidad dan como resultado dificultades de incorporación socio-laboral, situaciones de vulnerabilidad y exclusión social. En este documento se recogen, visualizan y comparan las diferentes prestaciones del ámbito ocupacional y laboral destinadas a las personas con enfermedad mental y discapacidad derivada de ésta de las siguientes Comunidades Autónomas uniprovinciales de España: Asturias, Cantabria, La Rioja, Madrid, Murcia y Navarra. A través del mismo, se puede conocer la situación laboral de las personas con enfermedad mental y discapacidad derivada de ésta y aclarar los tipos de Centros y programas específicos que hay para este colectivo en las diferentes Comunidades estudiadas. Se elaboran y aportan al trabajo tablas comparativas de síntesis de resultados para obtener una visión global de la situación estudiada.

Teaching Crossroads: 11th IPB Erasmus Week

In the wake of the latest news regarding IPB’s award for best Polytechnic Institute in Portugal, we would like to congratulate the IPB community who has always striven for the quality of the institution within the national and international academic milieu. We are, undoubtedly, bowled over by the 1st place in the national context (out of the 27 national institutions under evaluation) and the 7th position in the international scope. In fact, it is worth mentioning that the IPB has won this award, three years in a row, being in a leading position in the ranking promoted and sponsored by the European Union. This year’s edition has selected and evaluated over 1300 world higher education institutions. Teaching Crossroads intends thus to give a watershed contribution to the IPB’s successful and most valued pathway. Numbers indicate that Teaching Crossroads has had over 2550 downloads since it first came out. But let’s cut to the chase. Once again, we are delighted to present the 5th number of Teaching Crossroads. This wholly calculated and well-sustained editorial adventure started in 2012 when the first number of Teaching Crossroads first saw the light. This year’s publication includes the areas of Human Geography/anthropology, Information Technology and Forensics and Language and culture, focusing on minority languages. Alongside this, as in the two last previous numbers, we’ve included the specific area for International mobility, Intensive Programmes and Erasmus+ Mobility of Individuals, being the latter financed by the European Union within the Erasmus+ Programme, whereas the former is sponsored uniquely by the foreign partner institution, in this case, Lillebaelt Academy in Denmark. These types of programmes convey very positive and overarching ideas, resonant in cross-cultural and educational benefits, valuable for all the involved partners. We would very kindheartedly like to thank the authors for having contributed with much enlightening and serious articles on a wide array of areas. Pablo M. Orduna Pórtus’s article focuses on border culture and heritage management. The author’s study is placed on two borderlands of the Iberian Peninsula: Roncal Valley (Navarre) and Riverbanks of Douro. Going beyond the linear or physical conception of the border, the author centres his study on the metaphysical and symbolic ideas of the frontier that sustain his anthropological analysis. Michal Popdora manages to find evidence for his proposal of a new conception of teaching Image Processing, based on the student-centered approach. A hands-on experience on a Project-based Learning methodology sustains the teaching project. Grounded on “a forensic-flavored style”, using the author’s own words, he shows how students can become engaged in a highly effective learning process. Cláudia Martins is already a confirmed habitué of this publication, as in every Erasmus Week she delivers a lecture on Portuguese language and culture to visiting teaching and non-teaching staff. This time, the author decided to delve into a Portugal’s official language, Mirandese, spoken in a small designated area in the northeastern part of Portugal, Miranda do Douro and its surrounding area. The author gives account of some thought-provoking facts about the language, from the origin and the survival of the language, however still a minority language, up to the moment when it was acknowledged Portugal’s second official language, together with the challenges that nowadays faces. Luís Frölen Ribeiro, João Eduardo Ribeiro, Carlos Casimiro Costa, António Duarte, Carlos Andrade from the Polytechnic Institute and Arne Svinth, John Madsen, Morten Thomsen, Kent Smidstrup, Carsten John Jacobsen from the Lillebaelt Academy, in Denmark, participate in a joint project which they describe, outlining the main goals and gains of the project. To overcome teaching difficulties regarding the engineering degrees, a 12-ECTS joint course from Lillebaelt Academy and Polytechnic Institute of Bragança was created based on the Danish model. The course Product Development and Industrial Processing was hence created. Rui Pedro Lopes presents an insightful and acute account of the Internationalization programmes in Higher Education in Europe. At one go, the author describes his own experience as a visiting lecturer, within the Erasmus+ programme, to Università Politecnica delle Marche in Ancona, Italy, in a Master’s degree in computer science, bringing to light a personal reflection on the goals and benefits of the mobility for both students and teachers. Finally, the author puts forth some suggestions that would improve the whole mobility process. We sincerely hope to have stimulated you to keep on reading, upholding the belief that these texts can represent valuable sources for both teachers and students in their research work.
