Incidence of Fusarium foot and root rot of cereals under conservation agriculture in north west Tunisia
Get PDFConservation agriculture, based on direct drilling for crop establishment, has emerged in Tunisia since 1999/2000 as an alternative to conventional agriculture based on conventional drilling. The main objective of this approach is to ensure yield stability from crops and replenishment of soil organic matter. Previous research has demonstrated increased risks from pathogens favoured by mulching. The impacts of direct drilling on yields, and Fusarium foot and root rot of durum wheat, oat and barley, were studied over three successive growing seasons (2009/10, 2010/11, 2011/12) in northwest Tunisia. Disease incidence was estimated by the recovery frequency of Fusarium spp. isolates from stem bases and roots of plants of the three cereals. In addition, disease severity was assessed by occurrence of whiteheads that senesced prematurely, and the browning intensity on durum wheat stem bases. Grain yields were recorded at the ripening stages. Fusarium culmorum and F. pseudograminearum were isolated from the three cereals, with F. culmorum being the dominant pathogen. Direct drilling increased the incidence (60%) of these pathogens on stem bases and roots during the warmer seasons of 2009/10 and 2010/11, but less infection (37%) compared to conventional drilling was observed in the wetter season of 2011/12. Direct drilling increased the percentage of whiteheads of durum wheat (73%), but did not affect disease severity, which was estimated by the discolouration on stem bases and grain yield
Bulgaria, anno 1918: delusioni e speranze
Get PDFIn 1918 Bulgaria was supposed to celebrate 40 years from the liberation from Ottoman rule (1878) having gathered, as it was believed, all Bulgarian ethnolinguistic territory under the national flag. The end of the First World War, however, went differently for the Bulgarians and caused a deep hiatus after which nothing was as before. Paradoxically, it is precisely the warlike defeat that led to a total renewal of the Bulgarian culture and, in particular, of the literature to which this article is dedicated. The author takes a quick look at the previous century to better highlight the radical novelties in the Bulgarian post-1918 literature: 1) the denial of realism and patriotism – the two fundamental characteristics of Bulgarian literature after 1878, even when it waved the banner of modernism; 2) the aggressive entry of the expressionist and/or futurist poetics through the literary and editorial work of Geo Milev; 3) the anti-expressionist positions of the promoters of the ‘pansymbolism’ that presented itself as the alternative novelty in the field of art; 4) the romantic-revolutionary poetry of Ch. Smirnenski; 5) other post-war currents: diabolism, imaginism, female poetry, the ‘aestheticism’ of the group around the magazine “Zlatorog”.In 1918 Bulgaria was supposed to celebrate 40 years from the liberation from Ottoman rule (1878) having gathered, as it was believed, all Bulgarian ethnolinguistic territory under the national flag.

An English Island methodology: didactic strategies for learning English in Italian primary schools
Get PDFIn Italian primary schools the educational approach to teaching and learning foreign languages must be increasingly centered on the learner and focused on developing the acquisition of demonstrable competences through learning by doing. Based on a sequence of didactic strategies that form the circular learning path and on the association of three coded languages (mime, visual, oral), the methodology An English Island favours learner centered-instruction, as well as the learner’s active participation and involvement in creating the mental/physical grooves through which the language flows and turns into long-term memory.This paper focuses on the theoretical and methodological foundations of An English Island supported by a set of practical exercises that describe the educational process in which the teacher becomes the coach, observer, and scaffolder in order to train the citizens of the future
Life stories as a formative exercise for old women
Get PDFStarting from the idea that autobiography can be a way of caring-for-oneself – understood as an opportunity to rethink and re-engineer oneself at any age, this contribution will underscore the pedagogical potential of autobiographical narration as an existentially deliberate formative exercise capable of restoring a desire for ulteriority even at an age nearing the end of life.Specifically, an experiment carried out among elderly women was carried out as part of the “places and forms of care” workshop
Pedagogie comparate
Get PDFThe article proposes to present the disciplinary area in which could be placed a research field not studied yet. The name could be “Comparative Pedagogies”. This science is focused on the pedagogical theories and practices in their respective identities and differences, through comparisons of different kinds: (i) historical and geographical; (ii) anthropic, social and psychic; (iii) economic, political and legal; (iv) linguistic, literary and artistic; (v) mythological, esoteric, religious, philosophical and scientific
Gramsci lettore, interprete e diffusore di Marx
Get PDFThe aim of this article is to investigate the Gramsci’s interpretation of Marx, emphasizing both a series of training initiatives promoted by the Sardinian intellectual in order to spread and popularize his thought. Gramsci identifies some pedagogical consequences of the education principle of the “philosophy of praxis”
Sulle comunità di ricerca intellettuale: dal Quattrocento al Novecento. Una breve nota
Get PDFAt the beginning of the Sixteenth century, the Orti Oricellari became a real seedbed for intellectual life, where the ancient Plato’s style of “thinking together” was turned into a new dialogical argumentative model, open, critic, and even more connected to a pragmatically codified style of conversation. Since it developed in a high experience of thinking, it is also highly valuable from a pedagogical and educational point of view today
The assessment of compensation for the electric transmission line easement through a study of land market in Apulia
Get PDFHigh-voltage overhead transmission lines on farmland imply a permanent easement. System operators should compensate for expropriation of land and depreciation of the remaining farm area, but recognize only the former. Therefore, landowners often appeal to the law courts for fairer refunds.This study highlights that the area occupied by plinths and cabins, the height of pylons and the type of intersection are the main sources of depreciation. Moreover, electric transmission lines depreciate the residual farm area, but involving only two narrow strips of land on either side of infrastructures. Finally, the depreciation tends to decrease rapidly as the distance from the transmission line increases
Urban landscape assessment: a perceptual approach combining virtual reality and crowdsourced photo geodata
Get PDFThe paper focuses on the evaluation of the visual quality of the cityscape of Livorno, in Italy. Using an algorithm based on Flickr’s Application Programming Interface, the coordinates of 7,453 shooting points of a shared photo were downloaded. A direct survey was conducted to assess the perception of urban landscape. The geographical spaces to be evaluated were measured using 78 spherical images played in virtual reality through a virtual reality headset.The data were processed with the Principal Components Analysis. A Visual Quality Index (VQI) was developed to spatialise the results. Saliency maps were calculated to survey typical patterns in areas with high VQI. The results demonstrate how subjective visual perception helps identifying the criteria for the design of high-quality public spaces
