Fiber Bragg gratings of type I in SMF-28 and B/Ge fibre and type IIA B/Ge fibre under gamma radiation up to 0.54 MGy

The sensitivities of type I and IIA fibre Bragg gratings written to different reflectivities in SMF-28 and B/Ge fibres to ionizing radiation up to 0.54MGy are investigated. The Bragg wavelength shows a small and rapid increase at the start of irradiation followed by either a plateau (type I) or a decrease (type IIA).

A critique of a model for an academic staff activity database developed to aid a department in strategic and operational decision making

This paper discusses the use of a Model developed by Aston Business School to record the work load of its academic staff. By developing a database to register annual activity in all areas of teaching, administration and research the School has created a flexible tool which can be used for facilitating both day-to-day managerial and longer term strategic decisions. This paper gives a brief outline of the Model and discusses the factors which were taken into account when setting it up. Particular attention is paid to the uses made of the Model and the problems encountered in developing it. The paper concludes with an appraisal of the Model’s impact and of additional developments which are currently being considered. Aston Business School has had a Load Model in some form for many years. The Model has, however, been refined over the past five years, so that it has developed into a form which can be used for a far greater number of purposes within the School. The Model is coordinated by a small group of academic and administrative staff, chaired by the Head of the School. This group is responsible for the annual cycle of collecting and inputting data, validating returns, carrying out analyses of the raw data, and presenting the mater ial to different sections of the School. The authors of this paper are members of this steer ing group.

Techonology usage in the supply chain:the case of small 3PLs

In today's supply chain management practices, a successful strategy depends increasingly on the performance of third party logistics (3PLs) providers as they play a key integrative role linking the different supply chain elements more effectively. Information and communications technology (ICT) has become an important element of 3PL competitive capability as it enables higher levels of supply chain integration. Recent industry developments have widened the technological gap between large and small 3PLs. This is critical particularly for those markets populated by a large number of small 3PLs such as the Italian logistics industry. The purpose of this paper is to provide an overview of ICT adoption in small logistics service providers. The focus of the study is the Italian 3PL market. The methodology adopted in this paper is based on the action research framework and it is a combination of theoretical analysis and empirical findings (focus groups and surveys). Firstly, a literature review on ICT dissemination in the international and Italian 3PL industry has been carried out. Then, a field survey has been developed preceded by two focus groups. The empirical investigation examined a sample of 153 small Italian 3PLs on the base of a definition and taxonomy proposed by the authors. The results provide a useful technological profile of the surveyed companies, as well as an analysis of the role of ICT in customising services and of the factors influencing ICT adoption. To give a more robust scientific justification of the survey results, it would be useful to carry out an additional large-scale analysis including other countries with a high presence of small logistics service companies. Furthermore, a complementary case-study analysis would be of help in defining the role of specific factors in different types of 3PL. Further investigations in this field are needed to better understand innovation paths, and how ICT can improve the competitive capabilities of 3PLs and of the wider supply chain. Managers of small 3PLs can use the findings to set-up guidelines for improving a company's technology innovation. Technology vendors can use the findings to better market their service/product into the small logistics service provider segment. Despite the fact that much has been written about the dissemination of ICT, there is still a shortage of research in the field of small 3PLs with little empirical investigation into the usage of ICT by small 3PLs. This paper provides a contribution to filling this void and suggests some possible research directions.

Evaluating the use of IT by the third party logistics in South East Asia to achieve competitive advantage and its future trend

As the number of using 3PL providers are increasing rapidly in recent years, 3PL providers play a major role in the logistics industry. Due to customers demands are raising and changing, it has facilitated 3PL providers to invest IT systems that could meet customer requirements and create competitive advantage. The use of IT systems could assist 3PL providers to achieve supply chain visibility and enhance supply chain collaboration with business partners. In this paper, it is mainly focus on the Europe and Far East 3PL providers in terms of current and future IT systems, IT motivators and barriers, as well as the future supply chain demands that address by IT systems. The common IT system that implemented in both regions is information technology, which is mainly used to collaborate and share information with supply chain partners. Some of the common motivations and barriers were existed and 3PL providers need to be understood. Given the future demands of IT implementation and supply chain collaboration, IT systems such as RFID and integration systems would be strongly focus in the future. The suggestion about the advanced integration system such as business process management (BPM) could be the next key IT systems in the future logistics industry. © 2012 AICIT.

The analysis of potentiostatic transients applied to the corrosion of steel in concrete

Potentiostatically induced current transients obtained on a range of reinforced concrete specimens were analysed to give estimates of the polarisation resistance and interfacial capacitance. The polarisation resistance was compared with the values obtained using more conventional DC methods of analysis and, while it was consistently lower, it was within the error normally attributed to the polarisation resistance method of corrosion rate determination. The interfacial capacitance values determined increased from 0.44 F m -2 for passive steel (polarisation resistance of 132 Ω m 2) to 26.5 F m -2 for active steel (polarisation resistance of 0.34 Ω m 2). This has a dominant effect on the time required for potentiostatically induced current transients to reach a steady state with a longer time being required by actively corroding steel. By contrast the potential decay time constants describing galvanostatically or coulostatically induced potential transients decrease with an increase in corrosion rate and values less than 25 s for active specimens and greater than 40 s for passive specimens were determined in this work. © 1997 Elsevier Science Ltd.

GUIDE@HAND: Digital GPS Based Audio Guide that Brings the Past to Life

In the digital age the internet and the ICT devices changed our daily life and routines. It means we couldn't live without these services and devices anywhere (work, home, holiday, etc.). It can be experienced in the tourism sector; digital contents become key tools in the tourism of the 21st century; they will be able to adapt the traditional tourist guide methodology to the applications running on novel digital devices. Tourists belong to a new generation, an "ICT generation" using innovative tools, a new info-media to communicate. A possible direction for tourism development is to use modern ICT systems and devices. Besides participating in classical tours guided by travel guides, there is a new opportunity for individual tourists to enjoy high quality ICT based guided walks prepared on the knowledge of travel guides. The main idea of the GUIDE@HAND service is to use reusable, and create new tourism contents for an advanced mobile device, in order to give a contemporary answer to traditional systems of tourism information, by developing new tourism services based on digital contents for innovative mobile applications. The service is based on a new concept of enhancing territorial heritage and values, through knowledge, innovation, languages and multilingual solutions going along with new tourists‟ “sensitiveness”.

modern foreign languages classroom:is inclusion of all exclusion in disguise?

The past decade has seen a drive to give all pupils the opportunity to study a Modern Foreign Language (MFL) in schools in England, making the teaching and learning of foreign languages part of the primary school curriculum. The Languages for All: Languages for Life (DfES, 2002) policy was introduced through the National Languages Strategy with an objective to increase the nation’s language capability. Raising the educational standard for all pupils is another government initiative with a strong emphasis on inclusion. As the Languages for All policy stresses the importance and benefits of language learning, and inclusion suggests equality and provision for all, this study examines the inclusion of all key stage 2 pupils in foreign language learning and describes perceptions and experiences of pupils, particularly those identified as having special educational needs (SEN) in their performances and negotiations in learning French. As a small scale, qualitative and ethnographically informed, this research is based on participant observation and semi-structured interviews with pupils, teachers of French, teaching assistants and parents. This study draws upon Nussbaum’s capabilities approach and Bourdieu’s concepts as theoretical foundations to analyse the ‘inclusive’ French classroom. As the capabilities approach takes people as ends not means, and goes beyond a focus on resources, it lends itself to critical thinking on issues around inclusion in education. In this context, this researcher investigates the experiences of pupils who struggle with foreign language learning because of their abilities or disabilities, and frames the discussion around the capabilities approach. The study also focuses on motivation and identity in foreign language learning, and draws upon Bourdieu’s concepts of capital, habitus and field to analyse how the participants make sense of and respond to their own circumstances in relation to their performances in the language learning process. This research thus considers Bourdieu’s concepts for a deeper understanding of issues of inequality in learning French and takes up Nussbaum’s insight that pupils may differ in what learning French means to them, and it is not how they differ, but the difference between their capability to choose and achieve what they value that should matter. The findings indicate that although, initially, the French classroom appears ‘inclusive’ due to the provision and practices of inclusion, a closer look shows it to be exclusionary. In addition, responses from the participants on the usefulness and benefits of foreign language learning are contradictory to the objectives of the Languages for All policy, illustrating the complexity of the ‘inclusive’ MFL classroom. This research concludes that structural and interpersonal practices of inclusion contribute to the disguising of exclusion in a classroom deemed ‘inclusive’. Implications are that an understanding and consideration of other aspect of life such as well-being, interests, needs and values should form a necessary part of the language policy.

Mapping the nexus of transitional justice and peacebuilding

This paper explores the convergences and divergence between transitional justice and peace-building, by considering some of the recent developments in scholarship and practice. We examine the notion of ‘peace’ in transitional justice and the idea of ‘justice’ in peacebuilding. We highlight that transitional justice and peacebuilding often engage with similar or related ideas, though the scholarship on in each field has developed, largely, in parallel to each other, and of-ten without any significant engagement between the fields of inquiry. We also note that both fields share other commonalities, insofar as they often neglect questions of capital (political, social, economic) and at times, gender. We suggest that trying to locate the nexus in the first place draws attention to where peace and justice have actually got to be produced in order for there not to be conflict and violence. This in turn demonstrates that locally, ‘peace’ and ‘justice’ do not always look like the ‘peace’ and ‘justice’ drawn up by international donors and peace-builders; and, despite the ‘turn to the local’ in international relations, it is surprising just how many local and everyday dynamics are (dis)missed as sources of peace and justice, or potential avenues of addressing the past.

Fenton chemistry-based detemplation of an industrially relevant microcrystalline beta zeolite. Optimization and scaling-up studies

A mild template removal of microcrystalline beta zeolite, based on Fenton chemistry, was optimized. Fenton detemplation was studied in terms of applicability conditions window, reaction rate and scale up. TGA and CHN elemental analysis were used to evaluate the detemplation effectiveness, while ICP, XRD, LPHR-Ar physisorption, and 27Al MAS NMR were applied to characterize the structure and texture of the resulting materials. The material properties were compared to calcination. By understanding the interplay of relevant parameters of the Fenton chemistry, the process can be optimized in order to make it industrially attractive for scale-up. The H2O2 utilization can be minimized down to 15 mL H2O2/g (88 °C, 30 ppm Fe), implying a high solid concentration and low consumption of H2O2. When Fe concentration must be minimized, values as low as 5 ppm Fe can be applied (88 °C, 30 mL H2O2/g), to achieve full detemplation. The reaction time to completeness can be reduced to 5 h when combining a Fe-oxalate catalyst with UV radiation. The protocol was scaled up to 100 times larger its original recipe. In terms of the material's properties, the scaled material is structurally comparable to the calcined counterpart (comparable Si/Al and XRD patterns), while it displays benefits in terms of texture and Al-coordination, the latter with full preservation of the tetrahedral Al

A származtatott termékek árazása és annak problémái az egyensúlyelmélet szempontjából (Pricing of derived products and problems with it in terms of equilibrium theory)

A szerző röviden összefoglalja a származtatott termékek árazásával kapcsolatos legfontosabb ismereteket és problémákat. A derivatív árazás elmélete a piacon levő termékek közötti redundanciát kihasználva próbálja meghatározni az egyes termékek relatív árát. Ezt azonban csak teljes piacon lehet megtenni, és így csak teljes piac esetén lehetséges a hasznossági függvények fogalmát az elméletből és a ráépülő gyakorlatból elhagyni, ezért a kockázatsemleges árazás elve félrevezető. Másképpen fogalmazva: a származtatott termékek elmélete csak azon az áron képes a hasznossági függvény fogalmától megszabadulni, ha a piac szerkezetére a valóságban nem teljesülő megkötéseket tesz. Ennek hangsúlyozása mind a piaci gyakorlatban, mind az oktatásban elengedhetetlen. / === / The author sums up briefly the main aspects and problems to do with the pricing of derived products. The theory of derivative pricing uses the redundancy among products on the market to arrive at relative product prices. But this can be done only on a complete market, so that only with a complete market does it become possible to omit from the theory and the practice built upon it the concept of utility functions, and for that reason the principle of risk-neutral pricing is misleading. To put it another way, the theory of derived products is capable of freeing itself from the concept of utility functions only at a price where in practice it places impossible restrictions on the market structure. This it is essential to emphasize in market practice and in teaching.

A szovjetológiától az új intézményi közgazdaságtanig - töprengések két évtized távlatából = From Sovietology to the new institutional economics - meditations from a distance of two decades

A következőkben arra teszünk kísérletet, hogy összegezzük a közép- és a kelet-európai rendszerváltozások és az ezt tanulmányozók fordulatos történetét az elmúlt két évtizedben. Bemutatjuk, hogy a közgazdaságtan egy kevéssé fejlett ága miképp szembesült a tudományág egésze szempontjából is talán legnehezebb értelmezési és alkalmazási kérdéseket fölvető történelmi folyamattal. Megpróbáljuk feloldani azt a rejtvényt, hogy a főáramú megközelítés megismerése és alkalmazása miért nem hozott átütő eredményt sem a térség gazdaságainak, sem magának a tudományszaknak. Megvizsgáljuk a fokozatosság és a reformok kritikus tömege viszonyát. Végül kísérletet teszünk arra, hogy e sajátos szakterület elemzéséből adódó, tartósnak bizonyuló tételeket beépítsük a fenntartható fejlődés szélesebben értelmezett, immár főáramú megközelítéseibe. ___________ The article attempts to give an account of the changes of system in Central and Eastern Europe and of those who studied them in the last two decades. It shows how a less devel-oped branch of economics faced a historical process that posed possibly the most difficult questions of interpretation and application for the whole discipline. An attempt is made to discover why recognition and application of the mainstream approach failed to bring resounding success for the economies of the region or for economics itself. The author examines the relation between continuity and the critical weight of reforms. Finally, an attempt is made to advance durable propositions based on analysis of this specific field through now mainstream approaches in terms of sustainable development.

Governance in the European Union - Applying the "trilemma of global politics"

The European Union with its sophisticated institutional system is the most important regional integration on Earth. This tight form of economic integration converges to the level that Dani Rodrik calls hyperglobalization in his model, the political trilemma of globalisation. In our paper we develop the mentioned model and then we apply it to the case of the European Integration. We argue that if we want to maintain the deep integration among member states in the EU we have to pass more and more functions of the nation states to the federation level. In case of the EMU that means that federal fiscal policy is needed which could lead to multi-speed Europe considering new member states’ reluctance to give up their specific institutions.

Gazdasági kormányzás a gazdasági és monetáris unióban - a globális politika lehetetlen szentháromsága szemszögéből (Economic governance in the economic and monetary union – applying the trilemma of global politics)

Az Európai Unió a világgazdaság egyik legfontosabb integrációja. A benne megvalósuló gazdasági integráció szorossága megfelel annak a szintnek, amit Rodrik hiperglobalizációnak nevez. Az elmélet szerint a politika szintjén egyszerre nem megvalósítható a demokratikus politikai döntéshozatal, a teljes világgazdasági integráció, illetve a nemzetállam. A trilemma a globalizáció útjában álló intézményi különbségeken alapszik. Megoldása három módon lehetséges: a demokrácia kiiktatásával a megoldás az arany kényszerzubbony, ahol a piaci mechanizmusok veszik át az állami gazdaságpolitika szerepét; a globális kormányzás megvalósulása esetén a szuverén nemzetállamok tűnnek el a nemzetközi rendszerből; végül a Bretton Woods kompromisszum esetében a globalizáció útjába állítunk akadályokat. Írásunkban a modellt az európai integrációra, egészen pontosan a Gazdasági és Monetáris Unióra alkalmazzuk. Érvelésünk szerint, ha fent kívánjuk tartani az integráció szorosságát, erősíteni kell az integráció szintjén a gazdasági kormányzást, ami pedig csak a tagállami szuverenitás rovására mehet. Ez, mely a GMU esetében leginkább a fiskális föderáció erősítését jelenti ugyanakkor, megnövelve az integráció költségeit, egy többsebességes Európa kialakulása irányába hathat. _____ The European Union with its sophisticated institutional system is the most important regional integration on Earth. This tight form of economic integration converges to the level that Dani Rodrik calls hyperglobalization in his model, the political trilemma of globalisation. In this model Rodrik assumes that from the three desired element of world politics (deep economic integration, the nation state, and democratic politics) only two can be chosen. We can either choose deep integration and the nation state but then we have to abandon democracy; or we can choose deep integration and democracy, but then we have to forfeit the nation state; or we have to circumscribe globalisation to maintain democracy and the nation state. In our paper we develop the mentioned model and then we apply it to the case of the European integration. We argue that if we want to maintain the deep integration among member states in the EU we have to pass more and more functions of the nation states to the federation level. In case of the EMU that means that federal fiscal policy is needed which could lead to multi-speed Europe considering new member states reluctance to give up their specific institutions.

Do institutions matter in business strategy? – The changing focus of strategic management to institutions: a literature review

The post-crisis managerial literature emphasizes the roles of institutional factors in any disruption of the ecosystem of market capitalism and puts it in the middle of its analytical framework. It has become clear that nowadays, scientific discussions about the measure of increase of direct state involvement in certain economic areas has become more relevant. The socio-economic model based on market coordination was no doubt shaken by the crisis in 2008 across the world and inspired various representatives of the scientific and political community to revise their theses on coordination mechanisms that support the way out of an economic downturn. This paper intends to give a brief summary of the two leading strategic management approaches (Porter’s five forces and the resource-based view of the firm) on institutions. The author’s aim is to demonstrate that incorporation of the institution-based view into the mainstream theories can enrich the analytical framework of strategic management by providing deeper understanding of the contextual factors that underpin interactions between institutions and organizations.
