Risultati del programma DOCUP-SFOP 2000/2006
No full textObiettivo del presente lavoro è quello di analizzare le attività svolte dalla Regione Emilia Romagna nell’ambito del DOCUP-SFOP 2000-2006 nelle sue differenti iniziative intraprese attraverso la quantificazione delle domande e delle tipologie di intervento previste dai singoli bandi nelle diverse misure attivate. Viene, altresì affrontata la valutazione e il monitoraggio ex-post dei finanziamenti disponibili, impegnati ed erogati nelle differenti misure intraprese dal DOCUP-SFOP e nell’arco temporale in cui si è protratta la programmazione strutturale.
La valutazione è svolta attraverso la costruzione di un data base relativo alle singole domande pervenute e relative liquidazioni effettuate descrivendone le principali caratteristiche di intervento e le procedure adottate. A tale proposito sono stati individuati alcuni indicatori tecnici ed economici, sulla base dei dati disponibili, al fine di valutare le capacità organizzative e di spesa della Amministrazione pubblica e gli effetti prodotti dalle misure adottate sullo sviluppo e capacità competitiva della filiera ittica regionale.
Il lavoro si articola in più capitoli dove nella prima parte si affronta lo stato di attuazione del DOCUP-SFOP, evidenziando gli orientamenti legislativi europei dalla quale questo documento trae origine, per arrivare agli atti regionali con i quali si è dato inizio ai lavori. Il report prosegue con la descrizione delle attività del Programma SFOP e dei finanziamenti ad esso collegati. I capitoli 3, 4 e 5 affrontano, invece, la valutazione per Asse e per singole misure delle domande, dei contributi e dei pagamenti effettuati dalla Pubblica Amministrazione. In particolare, si è proceduto a illustrare le tipologie di investimento che i singoli beneficiari (privati e pubblici) hanno effettuato grazie ai finanziamenti pubblici, quindi ad analizzare gli aspetti finanziari del Programma DOCUP-SFOP attraverso la valutazione della capacità organizzativa e gestionale della Amministrazione regionale nella attivazione delle misure previste

No full textThe ability of Lysiphlebus testaceipes (Cresson) females to discriminate between parasitised and unparasitised Aphis gossypii Glover, and the mechanisms of host discrimination was studied. By comparing the resting time of parasitoid females on leaves with parasitised and unparasitised aphids their ability to host discriminate was evidenced. Y-tube olfactometer tests and direct observations of the searching behaviour of L. testaceipes females showed that the markers released during the parasitisation (at the insertion of the ovipositor and during egg laying) are perceived neither over long nor over short distance, but they are probably responsible of contact host discrimination. However, the parasitoids use their antennae to perceive olfactory cues and thus recognise parasitised hosts. The cues that act over short distance are directly or indirectly induced by the egg or the larva of the parasitoid developing inside the host

Full text linkThe development of improved technology for use of beneficial organisms in greenhouse crops includes mechanical application methods to that can reduce labour costs compared to manual application while preserving the quality of the applied natural ene-mies. A pneumatic distribution system, verified as effective in previous study with mites (Phytoseiulus persimilis Athias-Henriot and Amblyseius swirskii Athias-Henriot), was tested for application of the predatory bug Orius laevigatus (Fieber). Laboratory and field tests were used to assess the efficiency of mechanical distribution of nymphs of O. laevigatus. The efficiency of mechanical distribution was evaluated comparing the biological parameters of the predator (survival, fecundity, fecundity rate and lon-gevity) dispensed mechanically with to those following manual distribution. Nymphal survival immediately after and 10 days after the dispensing was calculated as proportion of nymphs reaching adulthood. We found that mechanical applications caused a reduction of predator survival in comparison to manual sprinkling of 21% and 36% immediately after and 10 days after the dis-pensing, respectively. The causes of the reduced survival from mechanical application were attributed to the combined effect of the extraction system and the velocity of airflow that transports the predator. Moreover, the biological parameters of adult females that survived mechanical distribution as nymphs, showed no significant differences compared to the same following manual dis-tribution. In the greenhouse test, the mechanically released nymphs of O. laevigatus were as effective as those manually released in controlling Frankliniella occidentalis (Pergande) in a cucumber crop. Consistently, the yield and quality of cucumber fruits did not show differences in the mechanical vs. manual application. Mechanical application time was significantly lower compared to manual application, determining a 5.5 higher effective work capacity compared to traditional manual distribution
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
