Urban agriculture and city development in Bologna (Italy): Notes in historical perspective
No full textIn the history of green spaces, in reference to horticulture and to other types of urban green, lives a constant relationship with the general history of urban development. Bologna (Italy) is an important case study: in this town, urban gardens and other green spaces have characterized large areas of the historic city from the Middle Ages to the Renaissance and onwards. Urban gardens are related (at least in a first historical phase) to subsistence agriculture; at the same time, the role of private gardens in several residential areas of the city should not be forgotten. The presence of large green areas - inside the city centre - remains considerable until the early 20th century, as shown also in many pictures and maps, some of which are currently available also on the internet. The history of the city's green crosses a more complex phase with the urban dynamics after the Italian Risorgimento
Green spaces in Italy from subsistence agriculture to public parks: The city of Bologna from 13th to 20th century
No full textAs many other European cities, Bologna has wide green spaces inside the city walls, especially in the Middle Ages, when the role of subsistence agriculture is really important; during the Renaissance, this scenario partially changes; and in the Modern Era the importance of gardens and public parks is growing. After Italian unification (1861), urban development enters into dialectical relationship with the protection of public green; new public gardens are built within the historic city and a large public park is inaugurated immediately outside the Renaissance walls. These events prelude to the urban development of Bologna outside its historical borders, according to a process that unites Bologna with several other cities of central and northern Italy, although with some differences with regard to policies for the protection of public green during the 20th century
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
La gramática: instrumento clásico profundamente renovado
Full text linkEn este capítulo se ofrece una visión de conjunto sobre la función, las peculiaridades, las clases y la estructura de los libros llamados “gramática” con la finalidad de facilitar su comprensión como instrumento y mejorar su uso. Para ello se abordan algunos pares de conceptos previos como la diferencia entre adquisición y aprendizaje, entre gramaticalidad y corrección, entre normativismo y descriptivismo. Se analiza, asimismo, los distintos tipos de gramáticas (pedagógicas, contrastivas, etc.) y los componentes estructurales del género textual denominado gramática
Effects of probiotic administration upon the composition and enzymatic activity of human fecal microbiota in patients with irritable bowel syndrome or functional diarrhea
No full textIn a clinical trial, 10 patients suffering from irritable bowel syndrome or functional diarrhea were administered the probiotic preparation VSL-3. Preliminary results indicated that administration of VSL-3 improved the clinical picture and changed the composition and biochemistry of fecal microbiota. Titer variations of intestinal bacterial groups were evaluated by culture and PCR techniques. A significant increase in lactobacilli, bifidobacteria and Streptococcus thermophilus was observed as a consequence of probiotic treatment, while enterococci, coliforms, Bacteroides and Clostridium perfringens did not change significantly. The strains Bifidobacterium infantis Y1 and Bifidobacterium breve Y8, included in VSL-3, were specifically detected in feces of patients treated with the probiotic by using strain-specific PCR primers. In addition, fecal β-galactosidase increased and urease activities decreased as a result of changes in the intestinal microbiota induced by VSL-3 administration. © 2001 Éditions scientifiques et médicales Elsevier SAS
Effects of temperature and host on the pre-imaginal development of the parasitoid Diglyphus isaea (Hymenoptera: Eulophidae)
No full textThe development of Diglyphus isaea (Walker), a parasitoid of leafminers, was studied under laboratory conditions at four constant temperatures (15, 20, 25, and 30degreesC on the hosts Liriomyza trifolii (Burgess) and Liriomyza huidobrensis (Blanchard) (Diptera: Agromyzidae). Parasitoid developmental time was found to be inversely related to temperature. At 15 degreesC, D. isaea took about 28 days to complete its development on L. huidobrensis and about 27 days on L. trifolii. In comparison, at 20degrees C developmental time dropped to half on both species and the same happened fro m 20 to 30degreesC. At 25degreesC, parasitoid development was complete after about 10 days. At all tested temperatures and on both host species, the length of pupal stage of the parasitoid was slightly shorter than the egg + larva period. Linear regression and the Logan model were used to describe the relationship between developmental rate and temperature. For egg to adult development, female D. isaea required 161.8 degree-days (DD) above the theoretical threshold of 9.2degreesC-on L. trifolii and 165.0 DD above 9.3degreesC on L. huidobrensis,and males required 151.4 DD above 9.5degreesC on L. trifold and 157.4 DD above 9.3degreesC on L. huidobrensis. Optimum temperatures for total female and male development on L. trifolii were 33.3 and 32.3degreesC, and on L. huidobrensis 32.6 and 31.0degreesC, respectively. The effects of host, sex, and temperature on parasitoid size were studied. Significant sex-temperature, host-temperature, and host-sex-temperature interactions were found. The host species was found to affect female parasitoid size differently based on temperature. (C) 2002 Elsevier Science (USA). All rights reserved
