Purpose : The aim of this paper is to provide novel insights into how the cosmopolitan mind-set can be fostered at a time of globalization by considering a group of social actors that has received scant attention in the literature on institutional change, notably migrant entrepreneurs. Design/methodology/approach : This is a conceptual study that draws on Bourdieu’s theory of capital to develop a set of testable propositions as to how the economic, cultural, social and symbolic capital endowments of migrant entrepreneurs shape their agency in bringing about cosmopolitan transformation. Findings : Together, migrant entrepreneurs endowed with higher levels of capital may act as institution reformers and promote the cosmopolitan mind-set by influencing the beliefs, incentives and behaviors of those embedded in more entrenched traditional institutions. Research limitations/implications : Our conceptual framework deals with only one of the many agents that may help bring about cosmopolitan change and is particularly well suited to a Western European context. Practical implications This conceptual paper provides a number of testable propositions that can be central to an empirical investigation into how the levels of capital possessed by migrant entrepreneurs affect their engagement in cosmopolitan change. Originality/value : The novelty of this paper lies in the development of a set of propositions that shows how divergent change toward a cosmopolitan vision might be engendered by spatially dispersed actors endowed with varying degrees of economic, cultural, social and symbolic capital.

This paper presents a diagnostic and prognostic condition monitoring method for insulated-gate bipolar transistor (IGBT) power modules for use primarily in electric vehicle applications. The wire-bond-related failure, one of the most commonly observed packaging failures, is investigated by analytical and experimental methods using the on-state voltage drop as a failure indicator. A sophisticated test bench is developed to generate and apply the required current/power pulses to the device under test. The proposed method is capable of detecting small changes in the failure indicators of the IGBTs and freewheeling diodes and its effectiveness is validated experimentally. The novelty of the work lies in the accurate online testing capacity for diagnostics and prognostics of the power module with a focus on the wire bonding faults, by injecting external currents into the power unit during the idle time. Test results show that the IGBT may sustain a loss of half the bond wires before the impending fault becomes catastrophic. The measurement circuitry can be embedded in the IGBT drive circuits and the measurements can be performed in situ when the electric vehicle stops in stop-and-go, red light traffic conditions, or during routine servicing.

In this concluding chapter, we bring together the threads and reflections on the chapters contained in this text and show how they relate to multi-level issues. The book has focused on the world of Human Resource Management (HRM) and the systems and practices it must put in place to foster innovation. Many of the contributions argue that in order to bring innovation about, organisations have to think carefully about the way in which they will integrate what is, in practice, organisationally relevant — but socially distributed — knowledge. They need to build a series of knowledge-intensive activities and networks, both within their own boundaries and across other important external inter-relationships. In so doing, they help to co-ordinate important information structures. They have, in effect, to find ways of enabling people to collaborate with each other at lower cost, by reducing both the costs of their co-ordination and the levels of unproductive search activity. They have to engineer these behaviours by reducing the risks for people that might be associated with incorrect ideas and help individuals, teams and business units to advance incomplete ideas that are so often difficult to codify. In short, a range of intangible assets must flow more rapidly throughout the organisation and an appropriate balance must be found between the rewards and incentives associated with creativity, novelty and innovation, versus the risks that innovation may also bring.

A műhelytanulmány célja, hogy megalapozzon egy, a lean menedzsment és a szervezeti kultúra kapcsolatát vizsgáló empirikus kutatást. Máig ritka a szűken vett témában született publikációk száma, ezért tanulmányunkban olyan forrásokat dolgozunk fel, amelyek a lean menedzsmenten túl a termelésmenedzsment más koncepcióit, gyakorlatait (minőségmenedzsment és a fejlett termelési rendszerek), az általuk elérhető teljesítmény és a szervezeti kultúra kapcsolatát értelmezi, vagy vizsgálja. A források módszeres áttekintésével azonosítjuk a kutatásokat indokoló tényezőket, az érintett termelésmenedzsment koncepciók értelmezéseit, a szervezeti kultúra értelmezéséket és a kutatási eredményeket. Mindezek alapján bemutatjuk, hogy melyek lehetnek azok a kérdések, melyek egy, a szervezeti kultúra és a lean menedzsment kapcsolatát vizsgáló empirikus kutatás során figyelmet érdemelnek. Bemutatjuk továbbá, hogy milyen egyéb tényezőkre kell figyelemmel lenni egy ilyen kutatás tervezése során. Önmagában a lean menedzsment, mint téma újszerű a szervezeti kultúrával kapcsolatos kutatások területén. Ezen túl a nagymintás és az angolszász területeken kívül eső kutatások kecsegtetnek jelentős új ismerettel. További újdonságot jelente a termelésmenedzsment koncepció és a szervezeti kultúra kapcsolatának megragadásán túl a kapcsolat természetének (a hatás irányának) feltárása. ______ The aim of this paper is to provide a solid base for a study that would examine the relationship between lean management and organizational culture. Since there are only limited number of publications in this topic, in our study we examined publications, which interpreted or examined the relationship among organizational culture, organizational performance and - beyond lean management - any operations management concepts or practices (but mainly quality management and advanced manufacturing technologies). Rigorously reviewing the selected sources, we identified the main questions justifying the researches, interpretations of the involved operations management concepts, interpretations of organization culture, and research results. Based on our review, we highlight those questions that are worth to examine within a research targeting to study the relationship between the organizational culture and lean management. Moreover, we identified other important factors to be considered when designing such research. Lean management by itself a novelty in the research field related to organizational culture. Moreover, large sample studies conducted outside the Anglo-Saxon territory likely to bring notable novelty. Further new knowledge may emerge if beyond capturing the existence of relationship among organizational culture and any operations management concept the nature of the relationship (the direction of the influence) was also investigated.

This article examines social attitudes towards risk-preference and risk-aversion. First, we briefly discuss the theoretical approach to the analysis of risk-preference and risk-aversion that was developed within rational choice theory. Next, we present an approach to operationalise risk-preference using survey data. Our measurement of attitudes towards risk follows the usual strategy: respondents are asked to choose between a small amount of money they get for sure, and a large but risky amount. Drawing on the theoretical models and earlier empirical research, we formulate hypotheses about the social factors that have an impact on actual decision making in the situations under study. The hypotheses are tested using survey data. The article ends with a brief discussion. The novelty of our paper is that – to the best of our knowledge – neither previous Hungarian nor international research has attempted to examine attitudes towards risk using data from large-scale surveys.

The present article assesses agency theory related problems contributing to the fall of shopping centers. The negative effects of the financial and economic downturn started in 2008 were accentuated in emerging markets like Romania. Several shopping centers were closed or sold through bankruptcy proceedings or forced execution. These failed shopping centers, 10 in number, were selected in order to assess agency theory problems contributing to the failure of shopping centers; as research method qualitative multiple cases-studies is used. Results suggest, that in all of the cases the risk adverse behavior of the External Investor- Principal, lead to risk sharing problems and subsequently to the fall of the shopping centers. In some of the cases Moral Hazard (lack of Developer-Agent’s know-how and experience) as well as Adverse Selection problems could be identified. The novelty of the topic for the shopping center industry and the empirical evidences confer a significant academic and practical value to the present article.

The allée is one of the oldest instruments and forms of landscape architecture, which has often been used from the Antiquity for the expression of visual and functional relationships, for the delimitation of space, or for the pictorial creation of movement. The several hundred years old allées of the late baroque age, which still live among us as the witnesses of bygone times, represent a special value throughout Europe. The longevity and the respectable size as such bestow a certain value upon the trees. However, the allées also stand for a garden art, landscape, culture historical and natural value, which in a summarized way are called cultural heritage. Furthermore, the gene pool of the proven longevous, high tolerance tree specimens is a natural and genetic heritage of scientific signification. The age of the trees and allées is finite. Even with a careful and professional care, the renewal is inevitable, which, beyond technical problems of landscape architecture might raise many scientific, nature conservation, yes, esthetical and ethical questions. This is why there is no universal methodology, but there are aspects and examination procedures of general validity with the help of which a renewal can be prepared. The renewal concept of the lime tree allée in Nagycenk aims at the protection and the transmission of the value-ensemble embodied in the allée. One part of the value-ensemble is the spiritual, cultural heritage, the extraordinary value of the landscape-scaled, landscape architectural creation planted and taken care of by the Széchenyis. On the other hand the two and a half centuries old trees represent an inestimable botanical and genetic wealth. Its transmission and preservation is a scientifically important program coming up to the Széchenyi heritage. After the registration of the originally planted old trees, the complete nursery material of the “Széchenyi limes” necessary for the replanting can be produced by vegetative propagation. The gradual replacement of the stand with its own propagation material, by the carefully raised nursery trees of the same age can be a model for the gene-authentic renewal method – a novelty even at an international level.

In this paper, I explore socio-spatial segregation from a particular perspective, which may probably be considered a novelty in the investigation of spatial social patterns, as it focuses on questions such as: What kind of distinction occurs between socio-spatial patterns designated by statistical data and the cognitive representations of those patterns in people's minds? and What explains these diff erences, and what kind of impact can they generate?

Stylization is a common method of ornamental plant use that imitates nature and evokes the scenery. This paper discloses a not yet proposed aspect of stylization, since the method offers the possibility of preserving the physiognomy of those habitats that seem to vanish due to future climate change. In addition, novelty of the method is founded also on that vulnerability of the Hungarian habitats has been examined by the researchers only from the botanical and ecological point of view so far and not in terms of its landscape design value. In Hungary, acidofrequent mixed forests appear to be highly sensitive to climate change according to ecological models. We are going to discuss the methodology of stylization of climate sensitive habitats and briefly refer to acidofrequent mixed forests as a case study. Those coniferous and deciduous tree species of the studied habitat that are water demanding are proposed to be substituted by drought tolerant ones with similar characteristics, and an optionally expandable list of these taxa is presented. Based on this the authors suggest experimental investigations of those of the proposed taxa for which the higher drought tolerance is based on observations only.

This paper investigates the impact of state subsidy on the behavior of the entrepreneur under asymmetric information. Several authors formulated concerns about state intervention as it can aggravate moral hazard in corporate financing. In the seminal paper of Holmström and Tirole (1997) a two-player moral hazard model is presented with an entrepreneur initiating a risky scalable project and a private investor (e.g. bank or venture capitalist) providing outside financing. The novelty of our research is that this basic moral hazard model is extended to the case of positive externalities and to three players by introducing the state subsidizing the project. It is shown that in the optimum, state subsidy does not harm, but improves the incentives of the entrepreneur to make efforts for the success of the project; hence in effect state intervention reduces moral hazard. Consequently, state subsidy increases social welfare which is defined as the sum of private and public net benefits. Also, the exact form of the state subsidy (ex-ante/ex-post, conditional/unconditional, refundable/nonrefundable) is irrelevant in respect of the optimal size and the total welfare effect of the project. Moreover, in case of nonrefundable subsidies state does not crowd out private investors; but on the contrary, by providing additional capital it boosts private financing. In case of refundable subsidies some crowding effects may occur depending on the subsidy form and the parameters.

The paper analyzes a special corporate banking product, the so called cash-pool, which gained remarkable popularity in the recent years as firms try to centralize and manage their liquidity more efficiently. The novelty of this paper is the formalization of a valuation model which can serve as a basis for a Monte Carlo simulation to assess the most important benefits of the firms arising from the pooling of their cash holdings. The literature emphasizes several benefits of cash-pooling such as interest rate savings, economy of scale and reduced cash-flow volatility. The presented model focuses on the interest rate savings complemented with a new aspect: the reduced counterparty risk toward the bank. The main conclusion of the analysis is that the value of a cash-pool is higher in case of firms with large, diverse and volatile cash-flows having less access to the capital markets especially if the partner bank is risky and offers a high interest spread. It is also shown that cash-pooling is not the privilege of large multinational firms any more as the initial direct costs can be easily regained within a year even in the case of SMEs.

The concept of a global civil society is gaining greater acceptance among International Relations (IR) scholars, yet few studies exist that look at the role of fraternal organizations and their influence in constructing this realm. Freemasonry, one of the oldest fraternal orders, exerts a powerful influence on its membership through its symbolism, architecture and ritual, based on the tenets of mutual respect and tolerance towards all human beings. Such principles helped in creating a body of practices and institutions as early as the eighteenth century which two hundred years later were identified and conceptualized as global civil society. ^ The allegations of anti-Masons and conspiracy theorists offer a continuous account of Masonry's influence on the political scene since its modern founding in 1717 Great Britain. Conspiracy theorists portray the coming of a New World Order, orchestrated and directed by a secret hierarchy of Masons/Illuminati. Even though the lens of conspiracy theories paints a distorted view of reality, it does focus attention to Freemasonry's activities as a major player in politics over the span of three centuries. Not only do such theories challenge the novelty of practices that make up a global civil society, but also the notion that it is an inclusive and growing sector that unites people across the globe. They also provide a valuable critique by pointing out the inconsistencies and discriminatory practices of Masonry as contrasted with the lofty ideals and aims for humanity. ^ The Masonic influence in the social world is perceived as one that reflects the liberal worldview where the nation-state and power structures are in pursuit of human progress, or profit. The symbolism of Masonry, however, carries a message that can be characterized as representing republican ideals. Masonic symbolism and ritual create spaces of meaning where the contradictions between the ideals and the structures of inequality and elitism can be resolved. Freemasonry as a symbolic system proclaiming their inherent republican values does have a global reach. However, the effectiveness of these values is bounded by the constraints that are inherent in a liberal world dominated by nation-states. ^

A high frequency physical phase variable electric machine model was developed using FE analysis. The model was implemented in a machine drive environment with hardware-in-the-loop. The novelty of the proposed model is that it is derived based on the actual geometrical and other physical information of the motor, considering each individual turn in the winding. This is the first attempt to develop such a model to obtain high frequency machine parameters without resorting to expensive experimental procedures currently in use. The model was used in a dynamic simulation environment to predict inverter-motor interaction. This includes motor terminal overvoltage, current spikes, as well as switching effects. In addition, a complete drive model was developed for electromagnetic interference (EMI) analysis and evaluation. This consists of the lumped parameter models of different system components, such as cable, inverter, and motor. The lumped parameter models enable faster simulations. The results obtained were verified by experimental measurements and excellent agreements were obtained. A change in the winding arrangement and its influence on the motor high frequency behavior has also been investigated. This was shown to have a little effect on the parameter values and in the motor high frequency behavior for equal number of turns. An accurate prediction of overvoltage and EMI in the design stages of the drive system would reduce the time required for the design modifications as well as for the evaluation of EMC compliance issues. The model can be utilized in the design optimization and insulation selection for motors. Use of this procedure could prove economical, as it would help designers develop and test new motor designs for the evaluation of operational impacts in various motor drive applications.

This dissertation explores the nature of Jose Marti's ethical ideas in relation to the rise of late Nineteenth Century Modernity and in tandem with the deconstruction and subversion of the principal constituencies of colonial and aesthetic discourses. Marti proposes a new paradigm that question the insatiable pursuit of novelty, the hostility towards tradition, the historical perspectivism and a critical stance with regard to social aesthetic Modernity. He also questions the cult of reason, the linear historicism, and the teleological progress framed in philosophical utilitarian pragmatism of bourgeois Modernity. His radical criticism of the structures and institutions of the hegemonic power of the modern state override the ontological and epistemological foundations of Modernity. Marti's deconstruction of the fundamental discourses of euro-centristic Occidental culture leads him, through his ethical writings, to an arqueology of Native American civilizations, thus reinserting, within the false premises of European universalism, his counter-discourse of tradition and the voice of the Other.

An emergency is a deviation from a planned course of events that endangers people, properties, or the environment. It can be described as an unexpected event that causes economic damage, destruction, and human suffering. When a disaster happens, Emergency Managers are expected to have a response plan to most likely disaster scenarios. Unlike earthquakes and terrorist attacks, a hurricane response plan can be activated ahead of time, since a hurricane is predicted at least five days before it makes landfall. This research looked into the logistics aspects of the problem, in an attempt to develop a hurricane relief distribution network model. We addressed the problem of how to efficiently and effectively deliver basic relief goods to victims of a hurricane disaster. Specifically, where to preposition State Staging Areas (SSA), which Points of Distributions (PODs) to activate, and the allocation of commodities to each POD. Previous research has addressed several of these issues, but not with the incorporation of the random behavior of the hurricane's intensity and path. This research presents a stochastic meta-model that deals with the location of SSAs and the allocation of commodities. The novelty of the model is that it treats the strength and path of the hurricane as stochastic processes, and models them as Discrete Markov Chains. The demand is also treated as stochastic parameter because it depends on the stochastic behavior of the hurricane. However, for the meta-model, the demand is an input that is determined using Hazards United States (HAZUS), a software developed by the Federal Emergency Management Agency (FEMA) that estimates losses due to hurricanes and floods. A solution heuristic has been developed based on simulated annealing. Since the meta-model is a multi-objective problem, the heuristic is a multi-objective simulated annealing (MOSA), in which the initial solution and the cooling rate were determined via a Design of Experiments. The experiment showed that the initial temperature (T0) is irrelevant, but temperature reduction (δ) must be very gradual. Assessment of the meta-model indicates that the Markov Chains performed as well or better than forecasts made by the National Hurricane Center (NHC). Tests of the MOSA showed that it provides solutions in an efficient manner. Thus, an illustrative example shows that the meta-model is practical.
