No full textPublic Capital, Employment and Total Factor Productivity: Evidence from Italian Transport Sector
No full textThis paper uses time series methodologies to examine the causal relationship among capital stock, total labour force and Total Factor Productivity (TFP) applied to transport sector for Italy, using annual data for the period 1970-2007. After an introduction, a literature review is carried out, before discussing the econometric methodology and data. Stationarity tests show that the series are clearly I(1) processes. Our estimation results indicate that one cointegrating relationship exists among these variables. Moreover, there is a bidirectional Granger causality flow between real public capital and labour force, as well as between public capital and TFP; while productivity Granger-causes labour force but not the other. The Forecast Errors Variance Decompositions (FEVD) show that errors in real public capital are mainly due to uncertainty in labour force and in public capital itself; and the labour force errors also become increasingly due to labour force and public capital; while the forecast errors in productivity are mainly due to TFP itself, although public capital is important as well
Venezia, Milano, Luino. Scambi epistolari tra Diego Valeri e Vittorio Sereni (1957-1976)
No full textDal carteggio intercorso tra Diego Valeri e Vittorio Sereni, oltre che l’amicizia affettuosa che lega i corrispondenti, emergono dei punti di contatto che illuminano una sorprendente affinità intellettuale tra due poeti solitamente ritenuti diversissimi per stile e contenuti. La scelta di lettere che propongo in questa sede desidera offrire a lettori e studiosi un campione significativo di questa corrispondenza
Un vero poeta se non canta canterà. Scambi epistolari tra Diego Valeri e Vittorio Sereni
No full textNon è abituale incontrare affiancati i nomi dei poeti Diego Valeri e Vittorio Sereni; all’uno e all’altro sono sempre assegnati un ruolo e uno spazio assai diversi all’interno della storiografia letteraria. La distanza di poesia che, è innegabile, si pone tra i due è meno ampia di quella che siamo soliti ritenere
Stakeholders Reactions to Urban Freight Policy Innovation
No full textUrbanfreightpolicies aim to minimise negative economic and environmental impact of freight movement in cities. At present, sustainable urbanfreight management is often hampered by a lack of awareness, not only of the local regulatory contexts, but also regarding acceptability and operative constrains of various distribution-chain stakeholders. This paper presents findings from a project investigating innovative freight solutions in a multi-stakeholder setting in Rome’s limited traffic zone focussing on local policy-makers, freight carries and retailers. The paper explores the responses of stakeholders in two consultation stages. Firstly, it examines the problem structure and policy sensitivity using in depth focus groups with stakeholders. Second, a survey with 195 operators is carried out to examine behavioural responses to policyinnovation on behalf of carriers, retailers and own-account operators. Results point towards heterogeneity in policy acceptability and reveal different operator’s stated reactions to innovative freightpolicies. The proposed empirical analysis considering multiple stakeholders points of view provides important inputs to improve freightpolicy design and analysis
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
