description: Countries, which have problems in the field of economic relations with aboard, usually misapply basic postulates and concepts of international marketing, as modern conceptions for achieving competitive advantage on international scale. Accordingly, this paper work researches the role of international marketing in the process of raising competitiveness of the agricultural and food products. Global marketing is facing a stronger and more complex challenge that needs faster and more subtle strategic responses. Namely, it must expect rapid changes, complex strategic situations, stricter and more unpredictable competition and changing mental maps of management, especially in regard to the affirmation of social awareness about the importance of respecting the environmental, social, political, cultural, and other components of the local market. Because the tastes, needs and consumer habits differ significantly, there is also justification for market segmentation of agri-food products.

description: We study the stability of a collisionless, relativistic, finite-strength, cylindrical layer of charged particles in free space by solving the linearized Vlasov-Maxwell equations and compute the power of the emitted electromagnetic waves. The layer is rotating in an external magnetic field parallel to the layer. This system is of interest to understanding the high brightness temperature of pulsars which cannot be explained by an incoherent radiation mechanism. Coherent synchrotron radiation has also been observed recently in bunch compressors used in particle accelerators. We consider equilibrium layers with a `thermal' energy spread and therefore a non-zero radial thickness. The particles interact with their retarded electromagnetic self-fields. The effect of the betatron oscillations is retained. A short azimuthal wavelength instability is found which causes a modulation of the charge and current densities. The growth rate is found to be an increasing function of the azimuthal wavenumber, a decreasing function of the Lorentz factor, and proportional to the square root of the total number of electrons. We argue that the growth of the unstable perturbation saturates when the trapping frequency of electrons in the wave becomes comparable to the growth rate. Owing to this saturation we can predict the radiation spectrum for a given set of parameters. Our predicted brightness temperatures are proportional to the square of the number of particles and scale by the inverse five-third power of the azimuthal wavenumber which is in rough accord with the observed spectra of radio pulsars.

Publisher: name: Zenodo
Year: 2022

description: Microgravity promotes changes at the cellular level as well as the genomic level. These changes contribute to the risks of abnormal physiological and neurological responses faced by astronauts during prolonged missions, for example, at the International Space Station (ISS). This study aims to investigate the potential effects of microgravity on gene expression levels of genes that are key to the central nervous system (CNS) especially the differentiation of stem cells into neurons. We use transcriptomic data from the Gene Expression Omnibus (GEO) as well as the NASA Gene Lab. We have identified 60 key genes that are important across the four stages of neuronal development. Beside these we identified 55 genes that were observed to be influenced when exposed to real microgravity at International Space Station (ISS). Following the detailed analysis of differentially expressed genes (DEGs) across these datasets, we intend to conduct a systems-level study using interaction network as well in order to study the functional interdependencies of the DEGs. We hope to understand how the CNS changes in response to, and adapts with, microgravity conditions.

title: The marginalisation of racism : a study of a local education authority project on multicultural education
Creators: name: Bagley, Carl Alexander
Publisher: name: The Open University
Year: 1991

description: The study originated from an independent evaluation of a Local Education Authority (LEA) project on multicultural education undertaken by a team of four teachers in two schools; a predominantly white, co-educational rural grammar school and a multi-racial, co-educational urban secondary modern. The thesis examines some key aspects of the conceptualisation, establishment, management and operationalisation of the project. The concepts of multicultural and antiracist education and the related research literature on their initiation in schools are considered. The procedures for the recruitment and selection of the project team are also examined along with the selection of the project schools, their organisation and ethos. The study focuses on the work of the team and their attempt to facilitate and initiate change at departmental and whole-school levels. The difficulty of the team's task and the complexity of racism are highlighted through a senior teacher's life history which examines his perspectives on 'race' and education. The research findings question the adoption of low-key multicultural approaches suggesting that they might marginalise the ability to address the issue of racism in schools and thus be counter-productive. Variables are also identified, in particular the occupational culture of teachers, which might have restricted the team's access to departments, the facilitation of collaborative teaching strategies and the implementation of whole-school policy. It is suggested that a team approach needs to be planned, executed and continually re-evaluated according to clear goals and shared objectives. It is also suggested that it might be advantageous for a team to possess subject-specific expertise and an ability to relate it to racism in the departmental curriculum. Moreover, throughout the process of change the issue of racism needs to remain explicit and, whenever possible, involve the black community in the decision-making process.

description: Nella prima parte del lavoro si definisce il Crowding Out, cioè la riduzione della spesa prevista provocata dall’aumento della spesa pubblica, e si analizzano i molteplici modi del suo operare con l’ausilio dello schema logico offerto dalle curve IS-LM. Nella seconda parte del lavoro si fa un discorso più ampio e realistico, con riferimento alle caratteristiche dell’economia italiana: apertura verso l’estero, impossibilità di influenzare prezzi e tassi del resto del mondo, esistenza di tensioni inflazionistiche. L’analisi è condotta dal punto di vista della Banca centrale, che affronta l’alternativa di finanziare il disavanzo pubblico o con creazione di base monetaria oppure consentendo un rialzo dei tassi tale da permettere il collocamento dei titoli del debito pubblico.

description: In 2013, the production of tractors as well as of majority of farm machines was smaller than a year earlier. Larger production was noted only in case of rototillers, fertiliser spreaders, harvester threshers, potato diggers and poultry facilities. In 2014, the production of tractors increased by 33.8%, but the production of harvester threshers decreased by 22.8% compared to 2013. In 2014, the share of Poland in the EU production of tractors (in units) amounted to 1.9% and in the total value of the means of agricultural mechanisation – 3.7%. The research showed no clear correlation between the domestic sales and production of tractors in Poland.

description: Exact solutions to a nonlinear Schr{ö}dinger lattice with a saturable nonlinearity are reported. For finite lattices we find two different standing-wave-like solutions, and for an infinite lattice we find a localized soliton-like solution. The existence requirements and stability of these solutions are discussed, and we find that our solutions are linearly stable in most cases. We also show that the effective Peierls-Nabarro barrier potential is nonzero thereby indicating that this discrete model is quite likely nonintegrable.

description: The automatic adjustment of earnings to the cost of living usually had two objectives, to protect wages in whole or in part from the effects of inflation and to avoid a spate of destabilising wage claims. Recently, however, in Italy a third aim has been added, that of reducing the differences in remuneration. The present article looks at the experience and prospects of wage indexing in Italy, limiting the analysis to the sliding-scale in industry. The author first considers how wage indexing works in Italian industry. The average effectiveness of wage indexing is then examined. Finally, the specific effectiveness of the method of indexing related to the unified value of the point is analysed. JEL: E31, E24, J31

description: Although even before the end of World War II the world was preparing itself to fight a relapse into stagnation, the harrowing role inflation was to have as a constant in the post-war economic scene was scarcely perceived. This resulted in several countries’ policy makers being caught off guard, with inflation proving to be a most intractable problem. The present article argues for a shift in emphasis in economic policy from monetary and fiscal issues towards growth, its determinants and its relationship to anti-inflation policies. The evolution of thinking on the problem of inflation is first considered. Employment and growth are then analysed in relation to inflation and economic policy. The author points out that full-employment and growth are neither synonymous nor interchangeable. JEL: E31, E24, E52, E62

Catalyst and methodology development for regioselective C-N and C-C bond formation
Creators: name: Lee, Alison Victoria
Publisher: name: University of British Columbia
Year: 2011

description: The related investigations of catalytic hydroamination as a key step in synthetic methodology development and the synthesis of new hydroamination catalysts are reported in this thesis. The first section focuses on methodology development for the application of a bis(amidate)bis(amido) titanium hydroamination precatalyst towards the synthesis of functionalized small molecules via a tandem C-N, C-C bond forming reaction sequence. The development of two tandem sequential reactions will be described, as well as their applications in the synthesis of α-cyanoamines, α-amino acid derivatives, β-amino alcohols, diamines, imidazolidinones, and β-amino acid derivatives. These tandem reactions show an expanded substrate scope and increase synthetic flexibility by allowing for alternative starting materials in the preparation of highly functionalized small molecules. The second section describes progress towards the development of an asymmetric tandem reaction sequence, including investigations into the mode of activation for the tandem reaction. It has been established that a nucleophilic activation mode is required to generate an active species for the C-C bond forming step. Furthermore, it is postulated that the coordination environment and steric congestion about the activator impacts reaction efficiency and stereoselectivity. This information will be valuable in the design of future generations of activators. The final section reports the development of two novel group 4 metal complexes for catalytic hydroamination. The synthesis and full characterization of these complexes will be described, as well as the results of the catalytic investigations. Through this investigation it has been postulated that while a change in the electronic nature of the metal complex does enhance catalytic reactivity, the degree of orbital overlap between the ligand and the metal center is also an important consideration in the design of electrophilic hydroamination precatalysts. Hydroamination catalysis is currently an attractive area of intense research. The work in this thesis has demonstrated the use of hydroamination catalysis in the synthesis of highly functionalized small molecules, and has furthered the fundamental understanding of the hydroamination reaction. This increase in understanding can then be applied towards the rational design of more powerful hydroamination catalysts and further their application in the synthesis of functionalized N-containing compounds.
title: Towards computer supported cooperative design

Publisher: name: The Open University
Year: 1999

description: This thesis first reviews the literature about the nature of cooperative design activity and its technological support. It is noted that knowledge of how designers work together in real-world settings is less than complete. Moreover, after over a decade of developments in Computer Supported Cooperative Work, the state-of-the-art in collaborative technology does not fully support such activities. Two substantial case studies are presented. The first draws upon fieldwork with designers at a large, distributed engineering design company, where a pilot study of collaborative technologies was carried out, focusing on the organisational context for such interventions and the reasons behind the qualified success of the experimental technology. In the light of the lack of use of synchronous tools in particular, a second case study was carried out. This was a complementary analysis of face-to-face co-working in a series of meetings held by a small design group. The results of both pieces of fieldwork are analysed in the context of existing studies of designers in both real-world and laboratory settings. This leads to the identification of a number of important characteristics of cooperative design, some newly identified, others confirming or extending the results of existing work. They include the identification of tension between traditional engineering design culture and the underlying assumptions of new technology; the intrinsic difficulties in sharing some types of design artefacts; and the way in which design entails an interweaving of individual and group activity, with consequences for resource exploitation, distributed cognition and workspace navigation in group sessions. The findings are integrated into an organising framework for cooperative design, with emphasis on the support of coworking designers distributed across multiple sites. Current technologies are reviewed against scenarios based on the framework and recommendations are made for further work.

title: The application of the planetarium as an education tool
Creators: name: Firniss, Kurt Paul
Publisher: name: The Open University
Year: 1981

description: "Planetariums are considered to be educationally valuable Teaching Tools and there seems to exist a Demand for them; but for a Variety of Reasons Planetariums are underused in Education." The study was stimulated by the fact that the planetarium as a theme has been completely neglected by educational research in the very country of its origin, Germany. Limited research done elsewhere is focussed on themes concerned with the selected application of the planetarium but no survey has been undertaken on its wider acceptance and its apparent underuse. A broad spectrum investigation has therefore been conducted, guided by the general hypothesis printed at the head of this abstract. The thesis is presented in 3 chapters: I Introduction with one essay on the "Science of Astronomy" and one essay on the "History , Purpose and Design of the Planetarium"; II The Educational Value and the Educational Potential of the Planetarium and Demand for School Planetariums; III The Underuse of the Planetarium. Actual work was preceded by initial exploratory and pilot surveys which established the relevance of the research problem, the validity of the hypothesis and the feasibility of the project. 6 opinion polls including tests with 535 planetarium visitors were conducted both internationally and nationally and also literature was evaluated in order to determine opinions and attitudes about the educational value and the educational potential of the planetarium and the demand for planetariums. All those concerned with the planetarium in one capacity or other were involved. The planetarium's intrinsic value was assessed from a study of the scope and quality of its functions as a teaching tool. Experiments performed in the planetarium confirmed the planetarium's effectiveness in both the cognitive and affective domains. Demand was also established on the level of the Ministries of Education but could not be confirmed as being known to the manufacturers. The underuse of the planetarium and many reasons responsible for it were confirmed by 9 further surveys. 20 surveys and 5 experiments involving the participation of N = 1187 subjects were conducted, and an advertising campaign with 2420 schools for school planetariums has been evaluated. The hypothesis was essentially supported by the results of the surveys conducted.

description: We compute the higher ramification groups and the Artin conductors of radical extensions of the rationals. As an application, we give formulas for their discriminant (using the conductor-discriminant formula). The interest in such number fields is due to the fact that they are among the simplest non-abelian extensions of the rationals (and so not classified by Class Field Theory). We show that this extensions have non integer jumps in the superior ramification groups, contrarily to the case of abelian extensions (as prescribed by Hasse-Arf theorem).

description: Recent research in the area of body image and body-image disturbance has increasingly examined cognitive information-processing models. The focus of the current study was on the processing of appearance-related and nonappearance-related information in appearance-schematic versus appearance-aschematic women. As a modified and extended replication of a study by Labarge, Cash, and Brown (in press), information processing was investigated using a computerized Stroop-type task. Participants were 128 Old Dominion University women who had previously completed the Appearance Schemas Inventory (ASI). They were divided into two groups based on their above median (appearance-schematic) or below-median (appearance-aschematic) ASI scores, Then, at designated times, these women individually completed two Stroop tasks, with an intervening task serving as either an appearance priming condition or a neutral control condition. The first Stroop task always used nonappearance words. The second Stroop task either used appearance words for the experimental group, or a second set of nonappearance words for the control group. After the second Stroop task, participants completed a verbal distractor task, and then a recognition task involving the Stroop words. It was hypothesized that appearance-schematic (versus appearance-aschematic) individuals, particularly those exposed to the appearance prime, would take longer to
color-name the words in the appearance-related matrix than in the nonappearance matrix. Further, it was hypothesized that primed appearance-schematic individuals would show faster, more accurate recognition of the appearance than nonappearance words to which they were exposed. Neither hypothesis was supported, although there was a trend in the predicted direction for primed schematics to be slower than the other three groups on Matrix 2 in relation to Matrix I. Possible explanations for these results are discussed. Finally, primed appearance-schematic individuals were expected to "inaccurately recognize" (i.e,, say they were exposed to a word when they really were not) more appearance than nonappearance words. This hypothesis was partially supported in that appearance-schematic individuals (though regardless of priming condition) were found to "inaccurately recognize" more appearance words than nonappearance words, g & .05. This may indicate that appearance-schematic individuals are hypersensitive to appearance relevant cues, and imagine that they receive more appearance-related input than they actually do. Implications for body-image therapy are discussed.

description: Let $z=(z_1, ..., z_n)$ and $Δ=\sum_{i=1}^n \fr {\p^2}{\p z^2_i}$ the Laplace operator. The main goal of the paper is to show that the well-known Jacobian conjecture without any additional conditions is equivalent to the following what we call {\it vanishing conjecture}: for any homogeneous polynomial $P(z)$ of degree $d=4$, if $Δ^m P^m(z)=0$ for all $m \geq 1$, then $Δ^m P^{m+1}(z)=0$ when $m>>0$, or equivalently, $Δ^m P^{m+1}(z)=0$ when $m> \fr 32 (3^{n-2}-1)$. It is also shown in this paper that the condition $Δ^m P^m(z)=0$ ($m \geq 1$) above is equivalent to the condition that $P(z)$ is Hessian nilpotent, i.e. the Hessian matrix $\Hes P(z)=(\fr {\p^2 P}{\p z_i\p z_j})$ is nilpotent. The goal is achieved by using the recent breakthrough work of M. de Bondt, A. van den Essen \cite{BE1} and various results obtained in this paper on Hessian nilpotent polynomials. Some further results on Hessian nilpotent polynomials and the vanishing conjecture above are also derived.

Subjects: subject: Inflation, Euro-currency market, credit
subject: E31, E44, E51

description: The inflationary implications of the Euro-currency market continue to be a source of contention and misunderstanding. One view on the matter is that the market, having some potential for net credit creation, adds dangerously to the rate of world credit expansion. As a challenge to this view, there are others who caution that the case for joint action is not yet well-founded. The author sides with the latter argument, arguing that considerable evidence can be found to show that the growth of the Euro-currency market represents to a significant extent a substitution for, rather than an addition to, credit expansion in other forms. Euro-currency credits appear to be substitutes for four alternative types of accommodation: domestic credit to non-banks, domestic “monetary base” creation, foreign money markets and forward exchange markets.

title: Artificial intelligence, education and music : the use of artificial intelligence to encourage and facilitate music composition by novices
Creators: name: Holland, Simon
Publisher: name: The Open University
Year: 1989

description: The goal of the research described in this thesis is to find ways of using artificial intelligence to encourage and facilitate music composition by musical novices, particularly those without traditional musical skills. Two complementary approaches are presented. We show how two recent cognitive theories of harmony can be used to design a new kind of direct manipulation tool for music, known as "Harmony Space", with the expressivity to allow novices to sketch, analyse, modify and compose harmonic sequences simply and clearly by moving two-dimensional patterns on a computer screen linker to a synthesizer. Harmony Space provides novices with a way of describing and controlling harmonic structures and relationships using a single, principled, uniform spatial metaphor at various musical levels; note level, interval level, chord level, harmonic succession level and key level. A prototype interface has been implemented to demonstrate the coherence and feasibility of the design. An investigation with a small number of subjects demonstrates that Harmony Space considerably reduces the prerequisites required for novices to learn about, sketch, analyse and experiment with harmony - activities that would normally be very difficult for them without considerable theoretical knowledge or instrumental skill. The second part of the thesis presents work towards a knowledge-based tutoring system to help novices using the interface to compose chord sequences. It is argued that traditional, remedial intelligent tutoring systems approaches are inadequate for tutoring in domains that require open-ended thinking. The foundation of a new approach is developed based on the exploration and transformation of case studies described in terms of chunks, styles and plans. This approach draws on a characterisation of creativity due to Johnson-Laird (1988). Programs have been implemented to illustrate the feasibility of key parts of the new approach.

description: On December 22, 1971, the Commission on Financial Structure and Regulation in the U.S. submitted its report on the structure, operation and regulation of the private financial system. The Commission’s recommendations are intended to make financial markets more competitive and to improve the ability of financial institutions to adapt to economic and technological change. While the present regulatory regime has had a long history and its consequences are reasonably familiar, the proposals for more competition would move the financial system in onto less familiar terrain.

description: Although large-scale commercial onion production began in Barbados about 1970, by 1987 77% of the annual demand was still being imported. Furthermore, exports declined from 7001 in 1972 to zero in 1987. The major factors that led to the decline in the industry were the seasonal production of the crop, 'blast' disease and the short shelf-life of the varieties grown. CARDI has been involved in a National Onion Development Programme, initiated in 1987, with the objective of removing these constraints to development of the onion industry. The other collaborators are the Ministry of Agriculture, onion growers, the University of the West Indies, the Sugar Technology Research Unit, and the Caribbean Meteorological Institute. The study undertaken by CARDI involved the testing of approximately 80 short and intermediate day onion varieties to select suitable high performance cultivars, adapted to climatic conditions in the Caribbean which would store well under ambient conditions. Two Israeli varieties, Grandstand and Arad, and Mercedes, a variety from the USA were selected because of their favourable yield and outstanding storability. These are the only varieties being produced commercially in Barbados at the present time. The period of availability of the local onion has been extended from 5 months in 1980 to 10 months in 1991. Export was restarted in 1995, with favourable response on bulb quality. There have been initiatives in onion production in St Kitts/Nevis, Grenada, St Vincent, Antigua and Montserrat. Transfer of technology from Barbados resulted in the transformation of the commercially grown varieties used in these countries between 1988 and 1993, with at least 9 0 ^ of the acreage cultivated to Grandstand and Arad. Although considerable progress has been made, constraints remain which must be addressed, e.g. the lack of adequate drying and storage facilities in all countries involved, control of weeds and 'blast' disease in the field, and the lack of proper production planning. The search for varieties tolerant to 'blast' continues.

Venusian Habitable Climate Scenarios: Modeling Venus through time and applications to slowly rotating Venus-Like Exoplanets

description: One popular view of Venus' climate history describes a world that has spent much of its life with surface liquid water, plate tectonics, and a stable temperate climate. Part of the basis for this optimistic scenario is the high deuterium to hydrogen ratio from the Pioneer Venus mission that was interpreted to imply Venus had a shallow ocean's worth of water throughout much of its history. Another view is that Venus had a long lived (approximately 100 million year) primordial magma ocean with a CO2 and steam atmosphere. Venus' long lived steam atmosphere would sufficient time to dissociate most of the water vapor, allow significant hydrogen escape and oxidize the magma ocean. A third scenario is that Venus had surface water and habitable conditions early in its history for a short period of time (< 1 Gyr), but that a moist/runaway greenhouse took effect because of a gradually warming sun, leaving the planet desiccated ever since. Using a general circulation model we demonstrate the viability of the first scenario using the few observational constraints available. We further speculate that Large Igneous Provinces and the global resurfacing 100s of millions of years ago played key roles in ending the clement period in its history and presenting the Venus we see today. The results have implications for what astronomers term "the habitable zone," and if Venus-like exoplanets exist with clement conditions akin to modern Earth we propose to place them in what we term the "optimistic Venus zone."

description: There have been notable developments in monetary theory over the last twenty years which have done much to clarify the role of monetary variables in economic activity and the related “transmission mechanism” of monetary policy. Even so, there are still conflicting theories and correspondingly lively debates between their proponents. The present article, within a general framework of the mechanism of monetary policy, looks at the relation between the results of these developments and their successive approximations used in empirical analyses of the effects of monetary policy. The author puts forward an aggregated model of the Italian monetary sector designed for short-term forecasting and policy, and considers the results of the economic estimates, its predictive performance and its policy implications.

description: A programme to increase the production of onion (Allium cepa) was initiated by the Caribbean Agricultural Research and Development Institute (CARDI) and the ministries of agriculture in 1990. The task force approach was the methodology adopted for the development of onion production. The task force included members from CARDI, the Ministry of Agriculture, the marketing agency and the onion growers. Through this interdisciplinary approach, production has increased from 7.5 ι in 1990 to 128 t in 1995. Average yield increased from 7,000 to 20,000 kg/ha, while average plot size increased from less than 100 m2 to 0.4 ha. The number of fanners involved in commercial onion production increased from five in 1990 to 24 in 1994. Two trial shipments to Dominica were completed in 1994 and 28 t were exported to Dominica in 1995. The use of the task force approach in expanding onion production in St Kitts and Nevis is examined.
title: Reservoirs of dignity and pride : schoolteachers and the creation of an educational alternative in Franco's Spain
Creators: name: O'Malley, Pamela
Publisher: name: The Open University
Year: 1990

description: This thesis consists, in the first place, of a social history of education in Spain, centred on the decade of the sixties which led up to the 1970 Education Act and the economic, political and social processes involved in the passing of this Act. At this time, Spain was still dominated by a fascist dictatorship but was emerging from its state of isolation created by Franco's victory in the Spanish Civil War and undergoing a process of great social and economic change. As a result a unique process of 'modernisation' full of contradictions and restraints owing to the fascist nature of the Regime took place. The thesis maintains that the education system was ill prepared for this challenge and indeed played a minor role in the social transformation produced by an important industrialising process and large migration to the industrial centres. The main part of the thesis is centred on teachers themselves and how they responded to the objective conditions analysed in the first part. Teachers found themselves immersed in a changing society and in an antiquated institution incapable of adapting to the changes. Even the so called reform proposed by the Regime was an attempt at apparent reform without change. Those teachers who developed politically and became active anti Regime militants, offered and aspired to a quite different educational solution expressed in the democratic 'Alternative. The development of a broad teachers' movement, of pedagogic groups and of a parents' movement, within the area of preschool, primary and secondary schooling is the main subject of this thesis. This study shows the difficulties of their activities under severely repressive conditions, and how their methods of struggle, the influence of its nature had on its content and the fact that their very opposition to the Regime represented a political advance in anti fascist resistance gave place to the development of a democratic 'Alternative' shared by all progressive teachers of the epoch.

description: Onions (Allium cepa L.) are a very popular, culinary, import commodity in the US Virgin Islands. Local production is minimal. Therefore, a large market exists for onions grown locally. Six short-day onion cultivars, 'Contessa', 'Granex 33*, 'Granex 429', 'Texas Grano 502', 'Texas Grano 1015' and 'Texas Grano 1025' were field evaluated during the 1994 and 1995 growing seasons. Parameters measured were bulb diameter, bulb height and yield. In 1994, Granex cultivars produced bulbs with the largest (Granex 429,77.4 mm) and smallest (Granex 33, 69.6 mm) diameters. Bulb height varied from 60.4 to 76.0 mm with the Texas Grano cultivars producing bulbs that were taller than the other cultivars. Mean yields of onions were significantly higher for Texas Grano 1015 (32.4 t/ha) compared to Texas Grano 502 and Granex 33 with yields of 25.1 and 18.6 t/ha, respectively. Granex 33, the earliest maturing of all the cultivars, produced the lowest yield and the smallest bulbs. In 1995, Texas Grano 1015 produced the largest bulbs (diameter and height) and also the highest yield. Increases in yields were observed for all cultivars in 1995 when compared with 1994. The time taken for cultivars to reach maturity was also longer during the second year.

description: Il documento analizza il processo di internazionalizzazione del settore bancario dal punto di vista delle strategie delle imprese in condizioni di oligopolio. Il caso italiano è interessante da questo punto di vista per la sua simultanea dinamica di ingresso di diversi attori stranieri nel mercato e internazionalizzazione di gruppi nazionali. Il lavoro discute la politica industriale appropriata in termini di armonizzazione della legislazione sovranazionale e delle esigenze di sviluppo del mercato interno. The paper analyses the process of internationalisation of the banking sector from the perspective of firms' strategies under conditions of oligopoly. The Italian case is interesting from this point of view for its simultaneous dynamics of entry of several foreign players in the market and internationalisation of domestic groups. The work discusses the appropriate industrial policy in terms of armonization of the supernational legislation and the development needs of the domestic market.
