title: The Royal Burgh of Peebles in the nineteenth century : the impact of a locally-organised railway on a moribund Scottish county town
Creators: name: Duncan, John Stuart
Publisher: name: The Open University
Year: 2005

description: Peebles, a small burgh in the Scottish Borders, was stagnant at the start of the 1800s, having remained virtually unchanged for 200 years. It was by-passed during the 1840s railway boom, the North British Railway (NBR) having decided that building a railway from Edinburgh to Peebles would be too costly. Local people then planned, built and ran the successful Peebles Railway, opened in 1855 as a 19-mile branch line linked to the NBR Edinburgh-Hawick route. It was an early example ofthe 'Cheap Railway Movement' in Britain.

 Within months, the town's com market had reopened, and the first of four woollen mills had begun production. The NBR and the Caledonian Railway soon provided additional rail links, and, as Peebles was no longer isolated, tourism blossomed because of the town's situation in beautiful countryside that had associations with Sir Walter Scott. The local Burgh and Grammar Schools were rebuilt, and low freight charges for building materials meant that the appearance of Peebles changed. New houses used sandstone instead of the local whinstone, and Welsh slates instead of thatch. A palatial Hydropathic was opened in 1881, which encouraged the' carriage' trade. The Parish Church became too small for the growing population, and was rebuilt in 1887, using expensive materials-an expression of the renewed confidence in the town.

This thesis explores why Peebles was stagnant in the first part of the nineteenth century. It reviews previous attempts to obtain a railway and the efforts of the Town Council to attract industry. The contribution of the Peebles Railway to the town and district is compared with those of a number of similar branch lines in Scotland and northern England. Much of the undoubted rejuvenation of the town is shown to be due to the three progenitors of the Peebles Railway Company, who were prominent members of the community.
Dark matter or correlated errors: Systematics of the AMS-02 antiproton excess

description: Several studies have pointed out an excess in the AMS-02 antiproton spectrum at rigidities of 10-20 GV. Its spectral properties were found to be consistent with a dark-matter particle of mass 50-100 GeV which annihilates hadronically at roughly the thermal rate. In this work, we reinvestigate the antiproton excess including all relevant sources of systematic errors. Most importantly, we perform a realistic estimate of the correlations in the AMS-02 systematic error which could potentially "fake" a dark-matter signal. The dominant systematics in the relevant rigidity range originate from uncertainties in the cross sections for absorption of cosmic rays within the detector material. For the first time, we calculate their correlations within the full Glauber-Gribov theory of inelastic scattering. The AMS-02 correlations enter our spectral search for dark matter in the form of covariance matrices which we make publicly available for the cosmic-ray community. We find that the global significance of the antiproton excess is reduced to below 1 $σ$ once all systematics, including the derived AMS-02 error correlations, are taken into account. No significant preference for a dark-matter signal in the AMS-02 antiproton data is found in the mass range 10-10000 GeV.

description: A thorough analysis of the stability of a coupled version of an inter-hemispheric 3-box model of Thermohaline Circulation (THC) is presented. This study follows a similarly structured analysis on an uncoupled version of the same model presented in Part I. We study how the strength of THC changes when the system undergoes forcings representing global warming conditions. Each perturbation to the initial equilibrium is characterized by the total radiative forcing realized, by the rate of increase, and by the North-South asymmetry. The choice of suitably defined metrics allows us to determine the boundary dividing the set of radiative forcing scenarios that lead the system to equilibria characterized by a THC pattern similar to the present one, from those that drive the system to equilibria where the THC is reversed. We also consider different choices for the atmospheric transport parameterizations and for the ratio between the high latitude to tropical radiative forcing. We generally find that fast forcings are more effective than slow forcings in disrupting the present THC pattern, forcings that are stronger in the northern box are also more effective in destabilizing the system, and that very slow forcings do not destabilize the system whatever their asymmetry, unless the radiative forcings are very asymmetric and the atmospheric transport is a relatively weak function of the meridional temperature gradient. The changes in the strength of the THC are primarily forced by changes in the latent heat transport in the hemisphere, because of its sensitivity to temperature that arises from the Clausius-Clapeyron relation.

description: This study investigates whether coupling crop modeling and machine learning (ML) improves corn yield predictions in the US Corn Belt. The main objectives are to explore whether a hybrid approach (crop modeling + ML) would result in better predictions, investigate which combinations of hybrid models provide the most accurate predictions, and determine the features from the crop modeling that are most effective to be integrated with ML for corn yield prediction. Five ML models (linear regression, LASSO, LightGBM, random forest, and XGBoost) and six ensemble models have been designed to address the research question. The results suggest that adding simulation crop model variables (APSIM) as input features to ML models can decrease yield prediction root mean squared error (RMSE) from 7 to 20%. Furthermore, we investigated partial inclusion of APSIM features in the ML prediction models and we found soil moisture related APSIM variables are most influential on the ML predictions followed by crop-related and phenology-related variables. Finally, based on feature importance measure, it has been observed that simulated APSIM average drought stress and average water table depth during the growing season are the most important APSIM inputs to ML. This result indicates that weather information alone is not sufficient and ML models need more hydrological inputs to make improved yield predictions.

Children's environmental knowing : a case study of children's experiences during an environmental education programme
Creators: name: Scott, Sandra Anne
Publisher: name: University of British Columbia
Year: 2011

description: This study explores children's experiences during WaterWorlds (pseudonym) a field-based environmental education programme at a marine science centre. The study objectives were to investigate how children understand and interpret their experiences, and how these experiences foster their environmental knowing. To address these objectives, I carried out a case study at a marine science centre in British Columbia. I examined children's WaterWorlds experiences and explored their environmental understandings and commitment to environmental action. I analysed the experiences of children in four separate classes and carried out an in-depth examination of four individual children. Data were collected using informal semi-structured interviews, observations, conversations, researcher journal logs, and student documents including their writing and illustrations. My findings indicate that the WaterWorlds programme experience fosters children's environmental knowing. Participation in WaterWorlds activities led to connection, caring, and concern for other species and in some cases, for the marine environment as a whole. During the programme, children chose the ways they interpreted and expressed their environmental knowledge, ethic of care, advocacy, and commitment to action. This development of each child's self-expression resulted in motivational and powerful learning experiences that inspired and nurtured their connections to the earth. This research provides evidence and examples of how educators can foster children's environmental knowing through multi-disciplinary environmental education experiences. It illustrates that activities such as observing and documenting the lives of other animal species, collecting data and conducting research on those species, and working and learning alongside experts in the field of environmental education are powerful experiences that motivate concern and care for the earth among children.
La politica monetaria e il problema delle aperture di credito. (Overdrafts and monetary policy)

subject: E51, E52, G21

description: The article analyses the overdraft system of bank lending and its potentially harmful effects on monetary policy. From the point of view of the economy as a whole, and for the purposes of monetary policy, three features characterise a banking system which uses the overdraft, as contrasted with the fixed loan, method of lending. First, a different significance attaches to “money supply” as an indicator of liquidity. Secondly, a different significance attaches to bank advances as an indicator of the volume of bank credit and of its effects on the level of spending. Finally, and most importantly, the monetary authorities face an additional difficulty in their efforts to keep the economy on an even keel. The author examines each of these features in turn.

description: Photo-induced edge states in low dimensional materials have attracted considerable attention due to the tunability of topological properties and dispersion. Specifically, graphene nanoribbons have been predicted to host chiral edge modes upon irradiation with circularly polarized light. Here, we present numerical calculations of time-resolved angle resolved photoemission spectroscopy (trARPES) and time-resolved resonant inelastic x-ray scattering (trRIXS) of a graphene nanoribbon. We characterize pump-probe spectroscopic signatures of photo-induced edge states, illustrate the origin of distinct spectral features that arise from Floquet topological edge modes, and investigate the roles of incoming photon energies and finite core-hole lifetime in RIXS. With momentum, energy, and time resolution, pump-probe spectroscopies can play an important role in understanding the behavior of photo-induced topological states of matter.
Composizione merceologica, distribuzione geografica e competitività nel commercio estero italiano nel periodo 1955-1963. (Developments in the commodity composition, market distribution, and competitiveness of Italy’s foreign trade, 1955-1963)

subject: F10, O52

description: Italy’s foreign trade increased spectacularly in the decade ending in 1963, a major factor contributing to its rapid economic growth in this period. However, following this period a new set of conditions emerged, resulting in an easing in the external payments situation. 1963 thus appears to mark a turning point in the rate and pattern of Italy’s economic growth. The present paper analyses this shift by reviewing the major developments that have occurred in foreign trade in the preceding years. The author determines the contributions to changes in total Italian exports which may be attributable to changes in the commodity composition, market distribution, and competitiveness of these exports. In addition, imports are examined with particular reference to changes in their commodity composition and regions of origin. JEL: F10, O52

title: Synthesis and characterisation of metal oxides and fluorinated perovskite-related oxides
Creators: name: Ren, Xiaolin
Publisher: name: The Open University
Year: 2005

description: Perovskite-related materials of composition LaFe1-xCoxO3 prepared by conventional calcination methods and mechanical milling are shown by temperature programmed reduction to be more susceptible to reduction in a flowing mixture of hydrogen and nitrogen by the incorporation of cobalt. X-ray powder diffraction and Mossbauer spectroscopy show that in iron-rich systems the limited reduction of iron and cobalt leads to the segregation of discrete metallic phases without destruction of the perovskite structure. In cobalt-rich systems, the reduction of Co3+ to Coo precedes complete reduction of Fe3+ and the segregation of alloy and metal phases is accompanied by destruction of the perovskite structure. Phases made by milling techniques were of smaller particle size and are more susceptible to hydrogen reduction than their counterparts made by conventional techniques. Materials of the type La0.5Sr0.5MO3 (M= Fe, Co) made by calcination methods are more susceptible to reduction when the transition metal M is cobalt as compared to iron.

 Perovskite-related oxides of composition La1-xSrxFe1-yCoyO3 have been fluorinated by reaction with poly(vinylidene fluoride). The materials have been characterised by X-ray powder diffraction and Mossbauer spectroscopy. Fluorination induces a reduction in the oxidation state of iron from Fe4+ to Fe3+. The fluorinated materials were magnetically ordered at 298 K.

 Compounds of the type SrFe1-xSnxO3 were found to contain Fe5+ and Fe3+. Fluorination resulted in reduction of the transition metal to Fe3+ and, in iron-rich systems, magnetic order. The compound Ba2SnO4 which adopts the K2NiF4-type structure has also been fluorinated by reaction with zinc fluoride. X-ray powder diffraction shows an enlargement of the unit cell of the fluorinated phase along the c-axis. Small particle iron- and vanadium- antimonate have been prepared by mechanical milling methods. The phases have been examined by M6ssbauer spectroscopy and can be formulated M3+Sb5+O4 (M = Fe, V). Thermal analysis suggests that the vanadium animonate formed by milling V2O5 and Sb2O3 in an inert atmosphere may be oxygen deficient. X-ray powder diffraction shows that milling also induces the phase transformation of the cubic senarmontite Sb2O3 form to the orthorhombic valentinite Sb2O3 form and of a-Sb2O4 to B-Sb2O4.

title: Anti-malaria drug treatment in Vietnam
Creators: name: Hien, Tran Tinh
Publisher: name: The Open University
Year: 2005

description: Resistance to antimalarial drugs is increasing nearly everywhere in the tropical world, confounding global attempts to "Roll Back Malaria". Antimalarial treatment with artemisinin, artesunate, or artemether has proved rapidly effective in the treatment of non complicated and complicated malaria and remarkably nontoxic. However there is a number of important questions that still need urgent attention: Should artemisinin be deployed alone or in combination with other antimalarial drugs such mefloquine or other compound (s); which is the best regimen (s); can artemisinin and its derivatives (artesunate or artemether) reduce the mortality in severe malaria and which is the best drug(s); are there important neurotoxic side effects in patients treated with this group of antimalarial drugs.

 In order to answer those questions a series of studies were conducted in Vietnam and these form the basis of this thesis. The conclusion is

 1/ Dihydroartemisinin-piperaquine is an inexpensive, safe, highly efficacious fixeddose antimalarial combination treatment that could make an important contribution to the control of multidrug-resistant fa1ciparum malaria for Vietnan1 and other countries.

 2/ Artemether is a satisfactory alternative to quinine for the treatment of severe malaria in adults. The rectal administration of artemisinin would obviollsly constitute a useful therapeutic advance, in comparing with parenteral drugs such as artemether and artesunate, particularly in areas where parenteral administration is difficult.

 3/ The artemisinin derivatives have an acceptable safety profile.

 4/ Viet Nam has shown that it is possible to "Roll Back Malaria" assuming one has access to good drugs and a willingness to implement change.

 Those studies have helped to confirm that the qinghaosu (artemisinin) group of drugs is the most important new class of antimalarials developed in the last fifty years.

description: The author spent two months in Togo in 1992 under the auspices of the U.S. Agency for International Development's Language, Culture and Professional Development (LCPD) Program. The purpose of this program is to enhance language skills and cultural understanding, and to provide professional development opportunities. As part of the professional development activities, the author attempted to gain an understanding of the dairy industry in Togo, including sources of supply, prices, consumption, industry structure, and government policies affecting the dairy industry. A literature search in the United States and in Togo yielded very limited and incomplete information, especially about the availability of different types of dairy products, their prices, and distribution channels. Therefore, an attempt was made to collect this type of information. However, the author's visit coincided with a period of political and civil unrest which, in combination with improved but scarcely adequate language skills, curtailed some opportunities for travel and information gathering and limited his ability to pursue certain issues and collect data. Consequently, the information presented is limited in scope. The publication begins with a description of Togo and its agricultural sector, to provide the setting for an assessment of the dairy industry. Conditions in Togo are similar to those in other Sub-Saharan countries.

description: Since the end of the Second World War the world economy has, apart from brief interludes of price stability, been in the grip of continuous inflation. No country seems to have managed to escape this world inflation entirely, although a few have made the very greatest efforts to do so. The present article considers why these efforts were in vain and if there really is no defence against “imported” world inflation. The author analyses the four types of policy for avoiding inflation - restrictive monetary and fiscal policy, export of capital, periodic changes in exchange parities and flexible exchange rates. The analysis suggests that the first two are least recommendable in the face of chronic balance of payments surpluses because they do not eradicate the surplus itself and can be sustained for only a relatively short period of time. The latter two do eliminate the external surplus, however, in the face of continuous world inflation, periodic revaluation does so only temporarily while flexible rates represent a permanent solution. The author concludes that world inflation can be checked only if there is an international monetary order which keeps reserves so scarce that no country feels able to allow inflation to proceed.

description: We study the predictive power of Skyrme forces with respect to low lying quadrupole spectra along the chains of Sn, Cd, and Te isotopes. Excitation energies and B(E2) values for the lowest quadrupole states are computed from a collective Schroedinger equation which as deduced through collective path generated by constraint Skyrme-Hartree-Fock (SHF) plus self-consistent cranking for the dynamical response. We compare the results from four different Skyrme forces, all treated with two different pairing forces (volume versus density-dependent pairing). The region around the neutron shell closure N=82 is very sensitive to changes in the Skyrme while the mid-shell isotopes in the region N<82 depend mainly on the adjustment of pairing. The neutron rich isotopes are most sensitive and depend on both aspects.

title: The role of apoptosis in in vitro and in vivo models of amyotrophic lateral sclerosis
Creators: name: Bigini, Paolo
Publisher: name: The Open University
Year: 2005

description: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease leading to motor neurons death. Although many studies were performed, the aetiology and the features of cellular death occurring in ALS are poorly understood, and studies carried out from autoptic samples do not allow to clarify early events occurring in ALS. To understand the basic mechanisms leading to motor neuronal death in ALS and to detect the different steps involved in motor neuron degeneration, alternative models are required. The wobbler mouse is one of the most reliable models of human motor neurodegenerative diseases. In the wobbler mouse neuromuscular deficits that are related to a selective vulnerability of cervical spinal cord motor neurons have an early onset and progress rapidly.

 In my project of thesis I first characterized apoptosis in primary cultures of motor neurons exposed to detrimental stimuli, and then I evaluated the possible involvement of apoptosis in the cervical spinal cord neurons of early symptomatic wobbler mice.

In primary cultures of motor neurons I found that: I) BDNF deprivation produced apoptotic cell death, II) AMPA and kainate induced apoptotic or non apoptotic cell death depending on the experimental conditions utilized, III) EPO selectively protected motor neurons committed to dye apoptically.

 In wobbler mice I found that: I) mitochondrial activity is reduced but caspase9 -mediated apoptosis does not seem involved, II) glutamate induced excitotoxicity does not seem involved in motor neuron degeneration, III) markers of neuroinflammation, such as activated microglia and TNF-a, appeared highly increased in the cervical region of early symptomatic wobbler mice but this process does not seem to induce the activation of caspase 8-mediated apoptosis.

 Pharmacological treatments confirmed that an antiglutamatergic agent (RPR 119990) and an antiapoptotic agent (EPO) were ineffective, while riluzole showed protective effects.

Although alternative cell death pathways should be investigated, my study excludes apoptosis as the mechanism of death in cervical motor neurons of wobbler mice.

description: Transition metal dichalcogenides are promising candidates to show long-range ferromagnetic order in the single-layer limit. Based on ab initio calculations, we report the emergence of a charge density wave (CDW) phase in monolayer 1T-CrTe$_2$. We demonstrate that this phase is the ground state in the single-layer limit at any strain value. We obtain an optical phonon mode of $1.96$ THz that connects CDW phase with the undistorted 1T phase. Localization of the $a_{1g}$ orbital of CrTe$_2$ produces an out-of-plane orientation of the magnetic moments, circumventing the restrictions of the Mermin-Wagner theorem and producing ferromagnetic long-range order in the two-dimensional limit. This orbital-localization is enhanced by the CDW phase. Tensile strain also increases the localization of this orbital driving the system to become ordered. CrTe$_2$ becomes an example of a material where the CDW phase produces the stabilization of the long-range ferromagnetic order. Our results show that both strain and phase switching are mechanisms to control the 2D ferromagnetic order of CrTe$_2$.

description: In recent years, Blockchain technology has been introduced with great success and has aroused the interest of the people to a great extent. Nowadays a big issue that concerns the society but also the scientists are the innovations that must be developed in the field of health and medical care. The purpose of this thesis is to first make a detailed analysis of technologies related to Blockchain technology, in order to fully understand its value. Then a very important part is the analysis of the benefits and weaknesses that such technology can bring to the medical field, since significant social, ethical, and other issues are raised. Reference will be made to some of the applications that have been implemented by various organizations and companies worldwide and are of considerable interest to be studied. Finally, a personal health file for the patient will be implemented where all the information will be stored. The user will be able to accept or reject requests from third parties requesting access but will also be able to access at any time to monitor the state of his data but also the answers he receives from doctors to his requests. More specifically, a private chain of nodes will be implemented with the use of appropriate software so that there is communication through the internet platform that will be developed and the private chain, in order to be user-friendly and easily accessible.
title: Creativity : psychological and evolutionary perspectives
Creators: name: Clegg, Helen Tarm

description: The most commonly cited explanation for the evolutionary emergence of creative ability is sexual selection. This suggests that the ability to produce creative products arose to advertise the qualities of the artist and thereby attract sexual partners. Thus the higher the quality of the product the greater the number of mates the artist will attract. The first study considered the definition of creativity by a general population and developed a measure of self-perceived creative ability. From the 344 participants it was found that creativity was predominantly considered to encompass Arts based activities. It was also considered by over 80% of the participants that creative products communicated something about the creative individual. The second study investigated whether artworks act as fitness indicators by accurately conveying the qualities of the artists. Six male artists each made an artwork and completed a personality inventory and an intelligence test. Fifty-one females rated the artists on creativity, intelligence and personality traits. Whilst intelligence was the only variable that was found to be significantly accurately assessed, qualitative analysis suggested that the raters were able to assess levels of personality traits but not to make subtle distinctions between these levels. Furthermore, these ratings were used in mate choice decisions when choosing which artist they would most like to go out on a date with. The final study was an online questionnaire asking artists about their artistic behaviours and attitudes, their and their partner's personality and their reproductive success. Results demonstrated that more professional male artists gained greater numbers of sexual partners and used a more short-term mating strategy. Moreover, both male and female professional artists had significantly greater potential fertility than less professional artists. These results strongly support the sexual selection theory for the emergence of creativity.
An analysis of gender and performance for students writing the British Columbia grade 12 provincial exams

description: Research on gender performance generally focuses on how boys and girls perform on standardized tests. Recent trends indicate that boys are doing worse than girls statistically in the areas of literacy and to a certain degree in the sciences. In British Columbia, students write provincial exams (standardized tests) at the end of a course. The exams count as 40% of their final grade. This study focuses on assessing whether there are significant differences in the mean scores of boys and girls over ten school years, from 1995-2005, in six provincial exam subjects: Biology 12, Communications 12, English 12, History 12, Principles of Mathematics 12, and Physics 12. Data were obtained from the Ministry of Education through Edudata. Independent t-tests were chosen to assess whether there were significant differences between male scores and female scores for each of the exams written for each school year. Findings from these analyses indicated that there were significant differences on mean scores in exams between males and females. Female students perform higher in Physics 12, Principles of Mathematics 12, English 12, and Communications 12 while male students perform higher in History 12. In Biology 12, there were years where males performed higher and other years where females performed higher.

description: Az Európai Unió bővítése számos területen eredményez merőben új helyzetet a tagállamok és az EU viszonyában. A közös politikák működési mechanizmusa 2004. május 1-től, egy az eddigiektől eltérő gazdasági közegben valósul meg. A megváltozó környezet a regionális politikát is érinti, mert az egyes területek közötti eddigi fejlettségbeli különbségek megváltoznak, és így a regionális fejlesztési források elosztása is megváltozik az Unióban. A jelenlegi tagországok között várhatóan lesznek olyan régiók, amelyek elveszíthetik fejlesztési forrásokra való jogosultságukat. A bővítés nyomán kialakuló helyzet a regionális gazdaságfejlesztés eszközrendszerének módosítását teheti szükségessé. ---------------- The expansion of the European Union will create a new situation in the field of mutual relation between member states and EU in several fields. After 1 May 2004 the mechanism of operation of common policies will be realised in an economic environment totally differing from the previous one. Changing environment affects also regional policy, since former differences in the degree of development between different regions will change as well, and the same will take place also in respect of the amounts allocated for regional development within EU having already 25 members instead of 15. As for the present member states, they will be likely to have regions which may loose their eligibility for development resources. Thus, the situation coming into being after EU expansion may necessitate a modification of the system of tools of regional economic development.
Lanczos recursion on a quantum computer for the Green's function and ground state
Creators: name: Baker, Thomas E.
Publisher: name: arXiv

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: A state-preserving quantum counting algorithm is used to obtain coefficients of a Lanczos recursion from a single ground state wavefunction on the quantum computer. This is used to compute the continued fraction representation of an interacting Green's function for use in condensed matter, particle physics, and other areas. The wavefunction does not need to be re-prepared at each iteration. The quantum algorithm represents an exponential reduction in memory over known classical methods. An extension of the method to determining the ground state is also discussed.

description: Il progetto di programma di sviluppo economico del paese tende sostanzialmente a stabilire le linee di evoluzione che la nostra struttura produttiva deve seguire per realizzare determinate finalità di ordine sociale e politico. La redazione del programma governativo ha perciò risposto non solo ad un’esigenza di ordine logico, ma anche ad un impegno democratico. I rilievi esposti nell’articolo non hanno mirato a porre in discussione quella finalità, ma semplicemente a collegare i mezzi e i fini e cioè a stabilire la conseguenza fra le previste modifiche nell’impiego delle risorse disponibili e le finalità politiche da conseguire.

title: Valuing bi- and multi-lingualism : a challenge to the monolingual framework for initial teacher training in secondary schools in England
Creators: name: Pearse, Valerie Sanchia
Publisher: name: The Open University
Year: 2006

description: This research investigates the perceived problem in initial teacher training of learning to teach bilingual pupils (TTA, 2004) in state secondary schools in England. It challenges the emphasis, within the national Standards for initial teacher training, on English as an additional language (EAL) (TTA, 2002), rather than the full spectrum of bilingual pupils. The thesis postulates that the national Standards privilege a monolingual perspective. This perspective maintains English as the dominant language within the education system rather than drawing on a more dynamic multilingual framework.

The data emanate from a multiple-site case study involving interviews in four schools and four Higher Education Institutions (HEIs) working in partnership to provide initial teacher training. The research examines underlying policies, beliefs and strategies.

The thesis concludes that the monolingual framework underpinning educational policy in England encourages a deficit model of bilingualism which determines the focus and discourse of policy and practice in initial teacher training. Few schools know how many bilingual pupils they have. This omission, combined with the focus on EAL in the Standards, means that trainees receive limited input on bilingualism from schools and HEIs. Trainers lack specific training in the benefits of bilingualism and rely on personal experience rather than theoretical knowledge. Consequently, trainees fail to draw on theories of language acquisition in their approach to teaching.

The research found that some schools and individual HEI trainers offered positive models. These encouraged trainees to place language learning at the heart of teaching and learning. Working directly with bilingual pupils helped. trainees to appreciate the potential of teaching within a multilingual framework. Future research could concentrate on bilingual pupils' perspectives and positive strategies employed in schools.

 This research advocates that economic and social benefits, including the promotion of global citizens who can appreciate other worldviews and be flexible in their thinking, could emerge from a multilingual framework.

description: A társaságnál központi szerepet játszik a likviditás és a pénzgazdálkodás javítása. Megállapítható, hogy a vizsgálatomba bevont vállalkozás helyzete kedvezőbb a mezőgazdasági átlagnál, mivel a nagyobb támogatottságú ágazatok (szarvasmarha, tej) meghatározóak a termelési szerkezetében. A társaság a mezőgazdasági átlagnál magasabb mértékű állami támogatással önfinanszírozó képességét növelte. Látható, hogy a mezőgazdaság kedvezőtlen jövedelmezőségi helyzete ellenére létezik átlagon felüli, jól működő vállalat. Ezek számának növelése kívánatos a további években. -------------- Liquidity and the improvement of finances play a central role in case of farming companies. The situation of the farming company investigated by the author is more favourable than the average in Hungarian agriculture, because sectors more heavily supported (i. e. the beef and dairy cattle sector) are decisive within its production structure. Due to state subsidies higher than the agricultural average the farming company was capable of raising its self-financing ability. It is obvious that, in spite of the unfavourable situation of Hungarian agriculture in terms of profitability, there are still farms more prosperous than the average. It is desirable to increase their number also in years to come.
