Breaking down the barriers to firm growth in Europe: The fourth EFIGE policy report. Bruegel Blueprint 18, 28 August 2012

Large firms contribute disproportionately to the economic performance of countries: they are more productive, pay higher wages, enjoy higher profits and are more successful in international markets. The differences between European countries in terms of the size of their firms are stark. Firms in Italy and Spain, for example, are on average 40 percent smaller than firms in Germany. The low average firm size translates into a chronic lack of large firms. In Italy and Spain, a mere 5 percent of manufacturing firms have more than 250 employees, compared to a much higher 11 percent in Germany. Understanding the roots of these differences is key to improving the economic performance of Europe’s lagging economies. So why is there so much variation in firm size in different European countries? What are the barriers that keep firms in some countries from growing? And which policies are likely to be most effective in breaking down those barriers? This policy report aims to answer these questions by developing a quantitative model of the seven European countries covered by the EFIGE survey (Austria, France, Germany, Hungary, Italy, Spain and the UK). The EFIGE survey asked 14,444 firms in those countries about their performance, their modes of internationalisation, their staffing decisions, their financing structure, and their competitive environment, among other topics.

LiDAR mapping of tidal marshes for ecogeomorphological modelling in the TIDE project

The European research project TIDE (Tidal Inlets Dynamics and Environment) is developing and validating coupled models describing the morphological, biological and ecological evolution of tidal environments. The interactions between the physical and biological processes occurring in these regions requires that the system be studied as a whole rather than as separate parts. Extensive use of remote sensing including LiDAR is being made to provide validation data for the modelling. This paper describes the different uses of LiDAR within the project and their relevance to the TIDE science objectives. LiDAR data have been acquired from three different environments, the Venice Lagoon in Italy, Morecambe Bay in England, and the Eden estuary in Scotland. LiDAR accuracy at each site has been evaluated using ground reference data acquired with differential GPS. A semi-automatic technique has been developed to extract tidal channel networks from LiDAR data either used alone or fused with aerial photography. While the resulting networks may require some correction, the procedure does allow network extraction over large areas using objective criteria and reduces fieldwork requirements. The networks extracted may subsequently be used in geomorphological analyses, for example to describe the drainage patterns induced by networks and to examine the rate of change of networks. Estimation of the heights of the low and sparse vegetation on marshes is being investigated by analysis of the statistical distribution of the measured LiDAR heights. Species having different mean heights may be separated using the first-order moments of the height distribution.

Sociodemographic determinants of diet quality of the EU elderly: a comparative analysis in four countries

Objective: To investigate the sociodemographic determinants of diet quality of the elderly in four EU countries. Design: Cross-sectional study. For each country, a regression was performed of a multidimensional index of dietary quality v. sociodemographic variables. Setting In Finland, Finnish Household Budget Survey (1998 and 2006); in Sweden, SNAC-K (2001–2004); in the UK, Expenditure & Food Survey (2006–07); in Italy, Multi-purpose Survey of Daily Life (2009). Subjects: One- and two-person households of over-50s (Finland, n 2994; UK, n 4749); over-50 s living alone or in two-person households (Italy, n 7564); over-60 s (Sweden, n 2023). Results: Diet quality among the EU elderly is both low on average and heterogeneous across individuals. The regression models explained a small but significant part of the observed heterogeneity in diet quality. Resource availability was associated with diet quality either negatively (Finland and UK) or in a non-linear or non-statistically significant manner (Italy and Sweden), as was the preference for food parameter. Education, not living alone and female gender were characteristics positively associated with diet quality with consistency across the four countries, unlike socio-professional status, age and seasonality. Regional differences within countries persisted even after controlling for the other sociodemographic variables. Conclusions: Poor dietary choices among the EU elderly were not caused by insufficient resources and informational measures could be successful in promoting healthy eating for healthy ageing. On the other hand, food habits appeared largely set in the latter part of life, with age and retirement having little influence on the healthiness of dietary choices.

Palaeobiology of the medieval population of Albano (Rome, Italy): a combined morphological and biomolecular approach

Recent years have seen increased interest in skeletal populations from the Imperial Roman Age in Italy, but much less is known about diet and standards of living in the subsequent medieval period. To fill this gap, we conducted a morphological analysis of human remains from Albano, an Italian town near Rome, as well as a stable isotope analysis of bone collagen to reconstruct diet. The sample was recovered from a Medieval cemetery (1040–1220 cal. yr. BP) located in the gardens of the historical Palazzo Doria Pamphili in Albano. A minimum number of 40 individuals (31 adults and 9 sub-adults) were examined using standard methods. Though the general health status of the population was good, signs of cribra orbitalia and diffuse enthesopathies were noted during the morphological examination. Stable carbon and nitrogen isotope analyses of the bone collagen from 24 adult humans and three faunal bones indicate that the diet of the population may be described as predominantly terrestrial and C3-plant based although the data for some of the individuals suggest a modest consumption of C4-(millet) based or aquatic proteins. No evidence of significant dietary differences between the sexes was found. The comparison of the isotope data from Albano with those from populations recovered in the same region is consistent with a shift from a terrestrial, possibly plant foods-dominated subsistence in the Early Middle Ages to a diet with a higher contribution from animal proteins, both terrestrial and aquatic, in the Later Middle Ages.

People or machines? Assessing the impacts of smart meters and load controllers in Italian office spaces

Government initiatives in several developed and developing countries to roll-out smart meters call for research on the sustainability impacts of these devices. In principle smart meters bring about higher control over energy theft and lower consumption, but require a high level of engagement by end-users. An alternative consists of load controllers, which control the load according to pre-set parameters. To date, research has focused on the impacts of these two alternatives separately. This study compares the sustainability impacts of smart meters and load controllers in an occupied office building in Italy. The assessment is carried out on three different floors of the same building. Findings show that demand reductions associated with a smart meter device are 5.2% higher than demand reductions associated with the load controller.

Mediating culture in the Italian literary field, 1940s-1950s: an introduction

This introduction lays out the scholarly and methodological context where to situate the contributions to this special issue. By combining a rigorous scrutiny of hitherto untapped archival sources with a re-examined application of Pierre Bourdieu’s sociology of culture within the field of periodical studies and publishing history in Italy (1940s-1950s), the studies illuminate the complex ways in which journals, periodical editors, and the connected publishing houses negotiate cultural practice in a literary field increasingly dominated by the polarization of political discourse.

A comparative study of internationalization potential for Italian SMEs in the fashion industry in Brazil and Russia

Este estudo tem como objetivo desenvolver uma análise comparativa do potencial de internacionalização na Rússia e no Brasil para as PME italianas que operam na indústria da moda. Depois de apresentar ao leitor as principais áreas cobertas, tais como, o contexto, a metodologia e revisão da literatura, é fornecido um panorama macroeconômico das áreas geográficas composto, englobando um estudo específico sobre o estado atual da economia e da demanda para os bens italianos. O estudo, introduzindo o leitor na indústria de moda italiana, suas principais características e o desempenho atual, já evidencia a busca pela internacionalização. As conclusões decorrentes das análises macroeconômicas funcionam como introdução à visão geral da indústria de moda italiana, uma indústria que representa, fortemente, o "Made in Italy" no exterior. A breve análise da história desta indústria, principais características e situação atual irão, então, sugerir que a internacionalização é o caminho mais viável às PME, para se recuperarem dos anos turbulentos da crise. Entre o vasto conjunto de opções geográficas que as PME têm para abraçar internacionalização, este estudo tem como objetivo fornecer duas análises sobre a indústria da moda: o mercado russo e o brasileiro. A análise, com base no quadro de capacidade de ‘resposta internacional’ proposto por Bartlet e Ghoshal (1989), apresenta os resultados de um conjunto de pesquisas e entrevistas realizadas no Brasil, na Itália e na Rússia, sob a forma de uma análise comparativa dos dois mercados-alvo. A análise evidenciará os drivers de mercado, custo, competitividade e legislação que justificam o processo de internacionalização em ambos os mercados. Os resultados levam à conclusão e às recomendações que os dois mercados representam duas oportunidades muito diferentes para as PME da indústria da moda italiana.

Determination of buprofezin, pyridaben, and tebufenpyrad residues by gas chromatography mass-selective detection in clementine citrus

A gas chromatography-mass-selective (GC-MS) detection method to determine buprofezin, pyridaben, and tebufenpyrad on the pulp, peel, and whole fruit of clementines is described. The extraction/partition procedure was performed in one step and no cleanup was necessary with the GC-MS in the SIM-mode pesticide determination. Recovery ranged from 75 to 124% with coefficients of variance ranging between 1 and 13%. The limit of determination was 0.01 mg/kg for all pesticides. The field trials showed a similar degradative behavior for all active ingredients (AI), with a great residue decrease during the first week and stability in the second. Just after treatment buprofezin and tebufenpyrad showed lower residues than the maximum residue limit (MRL) fixed in Italy, while pyridaben was below the MRL after a week.

Sul rinforzo di elementi in C.A.: confronto tra varie normative

Il documento pre-normativo italiano sul rinforzo di strutture in c.a. mediante l’uso di materiale fibrorinforzato. 1.1 INTRODUZIONE La situazione unica dell’Italia per quanto riguarda la conservazione delle costruzioni esistenti, è il risultato della combinazione di due aspetti, come primo, il medio-alto rischio sismico di una gran parte di territorio, come testimoniato dalla zonizzazione sismica recente, e come secondo aspetto, l'estrema complessità di un ambiente edilizio che non ha confronto nel mondo. Le tipologie della costruzione in Italia si distinguono a quelle stimate come patrimonio storico, che in alcuni casi risalgono a circa 2000 anni fa, a quelle che sono state costruite in ultimi cinque secoli, durante e dopo il Rinascimento, che sono considerate come patrimonio culturale ed architettonico dell' Italia (e del mondo!), infine a quelle fatte in tempi recenti, considerevolmente durante e dopo il boom economico del l960 ed ora visti come antiquate. Le due prime categorie in gran parte sono composte dalle edilizie di muratura, mentre agli ultimi principalmente appartengono le costruzioni di cemento armato.

Indagine sull’influenza di differenti sistemi d’allevamento sui connotati nutrizionali, tecnologici, sensoriali e di freschezza dell’orata (Sparus aurata) allevata in Italia

On account of the commercial importance of gilthead sea bream (Sparus aurata) in Italy the aim of the present study is the evaluation of the quality of nutritional, technological, sensory and freshness aspects. Sea bream production is growing in the Mediterranean and the evaluation of its quality concerns both producers and consumers alike. The culture system greatly influences final product quality. In Italy most of sea bream culture is carried out in cages but there is also a production in land based facilities and in lagoons. In this study external appeareance differentiations are pronounced. Different results were found for nutritional aspects, for fatty acids and for mineral content. Some differences in the freshness indices are also found. Furthermore, organoleptic differences have been described between culture system.

Il cinema in missione. La pratica cinematografica dei missionari italiani lungo il XX secolo tra apostolato e antropologia

The thesis reconstructs the cinema’s experience of Italian missionaries during the XX century in a historical-pragmatic key. Italian missionaries, who started producing movies around the Twenties, have used cinema as a helpful instrument for religious propaganda. They have considered the rules of the Catholic Church, the political and social context and the audience’s expectations. Each chapter (1-4) analyses the phenomenon inside the context constituted by the Italian colonial experiences, the relationship between Catholic Church and images during the Evangelization, the history of cinema and the history of missions. A specific chapter (chapter 5) is dedicated to the archives of missionary’s cinema and to the value to be assigned to this film production (in terms of social memory and archive’s memory). At the end of the first part, the thesis presents a proposal about the relationship between missionary’s cinema and visual anthropology. The second part of the thesis includes the film cards of the missionary’s movies preserved in Italy: 339 cards of Italian movies and 149 cards of foreign movies placed in different archives and bureaus.

La comunicazione chimica in Blattaria: contributo al miglioramento della lotta

CHEMICAL COMMUNICATION IN BLATTARIA: CONTRIBUTION TO THE IMPROVEMENT OF THE CONTROL TECNIQUES The management of cockroach infestations in urban environment has undergone some changes in recent years by moving to the predominant use of baits, thanks to the awareness of the risks connected with the use of spray insecticides. The effectiveness of a bait is determined by the collective performance of its components, including active and inert ingredients, the food attractant and any other attractive odour. This research has focused on the behavioral responses of Italian sinanthropic cockroaches to semiochemicals and food attractants, for the purpose of evaluating a possible practical application and of contributing to the improvement of control techniques. Behavioral and morphological studies have been carried out on Supella longipalpa (F.), a small cockroach that is spreading in Italy. Behavioral assays showed that the fourth and fifth tergites of females are significantly more attractive than other region of the body. Cuticular pores and ducts ending in glandular structures (observed with a S.E.M. = Scanning Electron Microscope) are present in large number on these tergites, suggesting that they could be involved in the production and the release of sexual pheromone. Cockroaches produce an aggregation pheromone that is excreted along with their frass and that consists of volatile and non-volatile compounds, mainly amines and steroidal glycosides. The effectiveness of faecal extracts obtained from excrements of Blattella germanica (L.), Blatta orientalis L., Periplaneta americana (L.) and S. longipalpa was evaluated, both at intraspecific and interspecific level, using a "Y" tube olfactometer. Bioassays showed that faecal extracts obtained with methanol have a good intraspecific attractiveness and, in some cases, they showed also interspecific behavioral responses. A gel was prepared, having physical characteristics that could give a good resistance to dehydration, as a potential basis for a new bait; the gel was then added faecal extracts, obtained with methanol from B. germanica and S. longipalpa frass. Arena-tests showed that the new gel containing faecal extracts is more attractive than some commercial gel formulations used as comparison: it was the only product that could attract 100% of insects placed in the arenas in 4-5 days. In conclusion, the substances involved in chemical communication of Blattaria may be able to effectively increase the attractiveness of products for monitoring and controlling cockroaches.

Strutture a pareti portanti in C. A. caratterizzate da elevate prestazioni sismiche

Per quanto riguarda le costruzioni in conglomerato cementizio armato gettato in opera, i sistemi strutturali più comunemente utilizzati sono quelli a telaio (con trasmissione di momento flettente), a setti portanti o una combinazione di entrambi. A partire dagli anni ’60, numerosissimi sono stati gli studi relativamente al comportamento sismico di strutture in c.a. a telaio. Lo stesso si può affermare per le costruzioni costituite da pareti miste a telai. In particolare, l’argomento della progettazione sismica di tali tipologie di edifici ha sempre riguardato soprattutto gli edifici alti nei quali, evidentemente, l’impiego delle pareti avveniva allo scopo di limitarne la elevata deformabilità. Il comportamento sismico di strutture realizzate interamente a pareti portanti in c.a. è stato meno studiato negli anni, nonostante si sia osservato che edifici realizzati mediante tali sistemi strutturali abbiano mostrato, in generale, pregevoli risorse di resistenza nei confronti di terremoti anche di elevata intensità. Negli ultimi 10 anni, l’ingegneria sismica si sta incentrando sull’approfondimento delle risorse di tipologie costruttive di cui si è sempre fatto largo uso in passato (tipicamente nei paesi dell’Europa continentale, in America latina, negli USA e anche in Italia), ma delle quali mancavano adeguate conoscenze scientifiche relativamente al loro comportamento in zona sismica. Tali tipologie riguardano sostanzialmente sistemi strutturali interamente costituiti da pareti portanti in c.a. per edifici di modesta altezza, usualmente utilizzati in un’edilizia caratterizzata da ridotti costi di realizzazione (fabbricati per abitazioni civili e/o uffici). Obiettivo “generale” del lavoro di ricerca qui presentato è lo studio del comportamento sismico di strutture realizzate interamente a setti portanti in c.a. e di modesta altezza (edilizia caratterizzata da ridotti costi di realizzazione). In particolare, le pareti che si intendono qui studiare sono caratterizzate da basse percentuali geometriche di armatura e sono realizzate secondo la tecnologia del cassero a perdere. A conoscenza dello scrivente, non sono mai stati realizzati, fino ad oggi, studi sperimentali ed analitici allo scopo di determinare il comportamento sismico di tali sistemi strutturali, mentre è ben noto il loro comportamento statico. In dettaglio, questo lavoro di ricerca ha il duplice scopo di: • ottenere un sistema strutturale caratterizzato da elevate prestazioni sismiche; • mettere a punto strumenti applicativi (congruenti e compatibili con le vigenti normative e dunque immediatamente utilizzabili dai progettisti) per la progettazione sismica dei pannelli portanti in c.a. oggetto del presente studio. Al fine di studiare il comportamento sismico e di individuare gli strumenti pratici per la progettazione, la ricerca è stata organizzata come segue: • identificazione delle caratteristiche delle strutture studiate, mediante lo sviluppo/specializzazione di opportune formulazioni analitiche; • progettazione, supervisione, ed interpretazione di una estesa campagna di prove sperimentali eseguita su pareti portanti in c.a. in vera grandezza, al fine di verificarne l’efficace comportamento sotto carico ciclico; • sviluppo di semplici indicazioni (regole) progettuali relativamente alle strutture a pareti in c.a. studiate, al fine di ottenere le caratteristiche prestazionali desiderate. I risultati delle prove sperimentali hanno mostrato di essere in accordo con le previsioni analitiche, a conferma della validità degli strumenti di predizione del comportamento di tali pannelli. Le elevatissime prestazioni riscontrate sia in termini di resistenza che in termini di duttilità hanno evidenziato come le strutture studiate, così messe a punto, abbiano manifestato un comportamento sismico più che soddisfacente.

Dalla Francia all'Italia: impegno politico, inchiesta e transfers culturali alle origini della sociologia del lavoro in Italia

Sociology of work in Italy revived at the end of WWII, after thirty years of forced oblivion. This thesis examines the history of discipline by considering three paths that it followed from its revival up to its institutionalization: the influence of the productivity drive, the role of trade unions and the activity of early young researchers. European Productivity Agency's Italian office Comitato Nazionale per la Produttività propagandised studies on management and on the effects of the industrialization on work and society. Academicians, technicians, psychologists who worked for CNP started rethinking sociology of work, but the managerial use of sociology was unacceptable for both trade unions and young researchers. So “free union” CISL created a School in Florence with an eager attention to social sciences as a medium to become a new model union, while Marxist CGIL, despite its ideological aversion to sociology, finally accepted the social sciences lexicon in order to explain the work changes and to resist against the employers' association offensive. On the other hand, political and social engagement led a first generation of sociologists to study social phenomenon in the recently industrialized Italy by using the sociological analysis. Finally, the thesis investigate the cultural transfers from France, whose industrial sociology (sociologie du travail) was considered as a reference in continental Europe. Nearby the wide importance of French sociologie, financially aided by planning institutions in order to employ it in the industrial reconstruction, other minor experiences such as the social surveys accomplished by worker-priests in the suburbs of industrial cities and the heterodox Marxism of the review “Socialisme ou Barbarie” influenced Italian sociology of work.
