Italian wild hop (Humulus lupulus L.): from biodiversity evaluation to varietal selection

Hop (Humulus lupulus L.) is a dioecius perennial plant. The cultivation is specific for female plants, used mainly for brewing and pharmacology. Female inflorescence, known as cone or strobili, contains bitter acids, essential oil and polyphenols. Commercial hop cultivation provides better results in regions between 45 and 55 degrees north or south in latitude, an area that also includes the northern part of Italy, where hop is endemic. Despite several studies have been conducted on the characterization of wild hops biodiversity in the U.S.A. and Europe, a lack in literature concerning the description of Italian wild hops genetic variability is still present. The increasing request of hop varieties improved in important traits, like diseases, resistance and valuable aroma profile, is bringing the hop industry. Moreover, Italian agricultural sector needs new impulse to be competitive in the market. In this view, Italian wild hop biodiversity is a resource, useful for the obtaining of Italian hop varieties, characterized by peculiar aromatic traits and more adaptable to Mediterranean climate, making their cultivation more sustainable. Based on this consideration, the present Ph.D. thesis deals with the evaluation of the Italian hop biodiversity, through the characterization of the wild samples under different point of view. The project started with the recovery of wild hop samples in different areas of north of Italy to consitue a collection field, where 11 commercial cultivars of US and European origin were grown, to have a complete vision of the hop panorama. Ph.D. project followed different research lines, the results of each one contributed to completly characterize the northern Italian hop wild biodiversity: • the morphological description showed a high phenological variability (Study 1); • the genetic characterization confirmed the rich biodiversity of the Italian population and showed a significant genetic distance between Italian genotypes and the commercial cultivars, taken in consideration (Study 2); • the need of an early sex discrimination method leads to an improvement of a genetic marker, developing a more efficient marker (Study 3); • a complete morphologic, genetic and chemical analysis of plants gave results to select the most promising genotypes (Study 4); • the comparison between the performance of wild hops and commercial cultivars in the same collection field indicated that some wild genotypes had a higher environment adaptability (Study 5); • the evaluation of the terroir, obtained comparing commercial cultivars in the collection field and the same genotypes purchased in the market, showed the influence of the northern Italian environment on the aromatic profile (Study 5); • a new analytical method for the revelation of bioactive metabolites and a simple extraction procedure were developed (Study 6). In conclusion, the Ph.D. thesis, contains the first characterization of Italian wild hop, made under field condition. The present study: i) permits to obtain a complete and significative description of the genotypes; ii) allows the identification of the most promising wild Italian genotypes; iii) allows the identification of commercial cultivars more adaptable the northern Italian climate.

O SILÊNCIO ESTÉTICO COMO ELEMENTO COMUNICACIONAL NA DIREÇÃO DE ARTE DO JOGO DIGITAL JOURNEY

Esta pesquisa propõe a abordagem teórica do silêncio como elemento comunicacional, como um elemento ligado a materialidade da linguagem, como um meio capaz de produzir ritmo narrativo e de edificar as bases projetuais destinadas ao desenvolvimento e a implementação da direção de arte em um projeto voltado a criação de Journey, um jogo digital independente para os videogames de sétima geração. O silêncio em Journey foi observado como elemento compositivo de linguagem, isto é, como aquilo que intencionalmente não foi dito, mas que conseguiu produzir algum tipo de efeito comunicacional no percurso da narrativa proposta para a trama. Assim, descobrimos os ambientes e os personagens que compõem o universo lúdico deste jogo digital por meio de um estudo de caso e da metáfora do silêncio, abordando os sistemas narrativos, as técnicas de direção de arte e as relações projetuais estabelecidas a partir deste contexto. Este é o objetivo central deste trabalho, traduzir o silêncio e suas ausências em um elemento comunicador, transformador da percepção e da sensibilidade dos jogadores por meio das narrativas e da direção de arte de uma expressão artística em forma de videogame.

Journey to work:exploring difficulties, solutions and the impact of aging

A study was conducted in the UK, as part of the New Dynamics of Ageing Working Late project, of the journey to work among 1215 older workers (age groups 45-49, 50-55, 56-60 and 60 + ). The aim was to identify problems or concerns that they might have with their commute, strategies that have been adopted to address them, and the role that employers can play to assist them. Follow-up interviews with 36 employees identified many strategies for assisting with the problems of journeys to work, ranging from car share and using public transport to flexible working and working some days from home. Further interviews with a sample of 12 mainly larger companies showed that employers feel a responsibility for their workers’ commute, with some offering schemes to assist them, such as adjusting work shift timings to facilitate easier parking. The research suggests that the journey to work presents difficulties for a significant minority of those aged over 45, including issues with cost, stress, health, fatigue and journey time. It may be possible to reduce the impact of these difficulties on employee decisions to change jobs or retire by assisting them to adopt mitigating strategies. It does not appear that the likelihood of experiencing a problem with the journey to work increases as the employee approaches retirement; therefore, any mitigating strategy is likely to help employees of all ages. These strategies have been disseminated to a wider audience through an online resource at www.workinglate.org.

The journey towards cultural competence

Graduates increasingly need to operate across national and cultural boundaries. This paper discusses the need to ensure that all students are equipped to operate within complex and diverse multicultural environments. The work builds on three earlier studies. Using these, the author has created a new theoretical framework and designed an intervention which aimed to increase diverse students' awareness of intercultural differences and their ability to function effectively in multicultural learning (and thus work) environments. The paper evaluates this highly innovative training. It concludes that it was effective in making a wide range of students aware of issues around cultural difference and competence. The training significantly changed the outlook of students who took part in it. Whilst the framework was robust, effective, and generalisable to other contexts, there are a number of issues which will be addressed in the re-running the programme.

The journey towards cultural competence: first interventions

Graduates worldwide are increasingly entering a global workplace which will require them to operate across national and cultural boundaries. This paper discusses the need to ensure that all students are equipped to work within this increasingly complex multi-cultural environment. It examines the issues which occur in preparing students within a UK Higher Education environment so that they are able to operate effectively within the international work situations in which they find themselves. This research builds on earlier research, which found that the effectiveness of an individual to work across cultural boundaries, in terms of work and communication, was increased by the number of international or intercultural experiences that a person has. Using this as a premise, an intervention was designed which aimed to increase students’ awareness of intercultural differences and their ability to function effectively in multicultural groups. This paper analyses the effectiveness of this highly innovative training intervention. It concludes that it was an effective way of making students aware of some of the issues around cultural competence is groups. In fact, the training was seen as most effective by students in addressing issues round group dynamics. The training obviously changed the outlook of a number students who took part it. There are, however, a number of issues which need to be addressed the re-running the training. These are notably, at what time in a student’s academic career such intervention is given, its integration into the curriculum and managing of student expectations.

Is competition really bad news for cooperatives? Some empirical evidence for Italian producers' cooperatives

In this paper, we analyse the nature of the relationship between market power and technical efficiency for producers' cooperatives. More specifically we test two hypotheses: first, we evaluate the extent to which increasing market pressure may help producers' cooperatives to improve technical efficiency to guarantee positive profits; second, we test whether higher technical efficiency induces producers' cooperatives to have a larger market share. These hypotheses are tested on a sample of Italian conventional and cooperative firms for the Wine Production and Processing sector, using both frontier analysis and dynamic panel techniques. The results support the hypothesis that increasing market pressure can affect positively the cooperativeś efficiency, while gains in technical efficiency do not seem to have any impact on the cooperatives' market share. © 2008 Springer Science+Business Media, LLC.

Patterns of corporate governance and technical efficiency in Italian manufacturing

The purpose of this paper is to analyse the relationship between the corporate governance system and technical efficiency in Italian manufacturing. We use a non-parametric frontier technique (DEA) to derive technical efficiency measures for a sample of Italian firms taken from nine manufacturing industries. These measures are then related to the characteristics of the corporate governance system. Two of these characteristics turn out to have a positive impact on technical efficiency: the percentage of the company shares owned by the largest shareholder and the fact that a firm belongs to a pyramidal group. Interestingly, a trade-off emerges between these influences, in the sense that one is stronger in industries where the other is weaker. Copyright © 2007 John Wiley & Sons, Ltd.

Public capital and total factor productivity:new evidence from the Italian regions, 1970-98

This paper analyses the relationship between industrial total factor productivity and public capital across the 20 Italian administrative regions. It adds upon the existing literature in a number of ways: it analyses a longer period (1970-98); it allows for the role of human capital accumulation; it tests for the existence of a long-run relationship between total factor productivity and public capital (through previously suggested panel techniques) and for weak exogeneity of public capital; and it assesses the significance of public capital within a non-parametric set-up based on the Free Disposal Hull. The results confirm that public capital has a significant impact on the evolution of total factor productivity, particularly in the Southern regions. This impact is mainly ascribed to the core infrastructures (road and airports, harbours, railroads, water and electricity, telecommunications). Also, core infrastructures are weakly exogenous. © 2005 Regional Studies Association.

Organizational capital, product market competition and technical efficiency in Italian cooperatives

This paper tries to identify under which conditions increasing market competition may help cooperatives to improve technical efficiency to guarantee positive profits. This hypothesis is first formalized in a partial equilibrium framework and then is tested on a sample of Italian conventional and cooperative firms, using frontier analysis. Technical efficiency indexes are computed by using the one-stage approach as suggested by Battese and Coelli (1995), where proxies for competition are introduced as determinants of efficiency, along with other exogenous factors accounting for the firms’ heterogeneity. However, the overall impact of increasing competition on efficiency is negative.

Making a journey in knowledge management strategy

This paper reports results from an ongoing project examining what managers think about knowledge management in the context of their organisation. This was done in a facilitated computerassisted group workshop environment. Here we compare the outcomes of workshops held for two relatively large UK organisations, one public sector and the other private. Our conclusions are that there are relatively few differences between the perceptions of these two groups of managers, and that these differences stem more from the stage of the knowledge management life cycle that the two organisations have reached, rather than from the difference in context between public and private sector. © iKMS & World Scientific Publishing Co.

Journey making group workshops as a research tool

Problem-structuring group workshops can be used in organizations as a consulting tool and as a research tool. One example of the latter is using a problem-structuring method (PSM) to help a group tackle an organizational issue; meanwhile, researchers collect the participants' initial views, discussion of divergent views, the negotiated agreement, and the reasoning for outcomes emerging. Technology can help by supporting participants in freely sharing their opinions and by logging data for post-workshop analyses. For example, computers let participants share views anonymously and without being influenced by others (as well as logging those views), and video-cameras can record discussions and intra-group dynamics. This paper evaluates whether technology-supported Journey Making workshops can be effective research tools that can capture quality research data when compared against theoretical performance benchmarks and other qualitative research tools. © 2006 Operational Research Society Ltd.

Italian validation of the team climate inventory:a measure of team climate for innovation

Innovation has long been an area of interest to social scientists, and particularly to psychologists working in organisational settings. The team climate inventory (TCI) is a facet-specific measure of team climate for innovation that provides a picture of the level and quality of teamwork in a unit using a series of Likert scales. This paper describes its Italian validation in 585 working group members employed in health-related and other contexts. The data were evaluated by means of factorial analysis (including an analysis of the internal consistency of the scales) and Pearson’s product moment correlations. The results show the internal consistency of the scales and the satisfactory factorial structure of the inventory, despite some variations in the factorial structure mainly due to cultural differences and the specific nature of Italian organisational systems.

The Generalized Malmquist index and capacity utilization change: an application to the Italian manufacturing, 1989-1994

Several indices of plant capacity utilization based on the concept of best practice frontier have been proposed in the literature (Fare et al. 1992; De Borger and Kerstens, 1998). This paper suggests an alternative measure of capacity utilization change based on Generalized Malmquist index, proposed by Grifell-Tatje' and Lovell in 1998. The advantage of this specification is that it allows the measurement of productivity growth ignoring the nature of scale economies. Afterwards, this index is used to measure capacity change of a panel of Italian firms over the period 1989-94 using Data Envelopment Analysis and then its abilities of explaining the short-run movements of output are assessed.
