Founders' human capital and the performance of UK new technology based firms

This paper investigates the role of entrepreneurs' general and specific human capital on the performance of UK new technology based firms using a resource based approach to the entrepreneurship theory. The effect of entrepreneurial human capital on the performance of NTBFs is investigated using data derived from a survey of 412 firms operating in both high-tech manufacturing and the services sectors. According to the resource based theory it is found that specific human capital is more important for the performance of NTBFs in relation to general. More specifically individual entrepreneurs or entrepreneurial teams with high levels of formal business education, commercial, managerial or same sector experience are found to have created better performing NTBFs. Finally it is found that the performance of a NTBF can improve through the combination of heterogeneous but complementary skills, including, for example, technical education and commercial experience or managerial technical and managerial commercial experience. © 2010 Springer Science+Business Media, LLC.

Sub-critical regime of femtosecond inscription

We apply well known nonlinear diffraction theory governing focusing of a powerful light beam of arbitrary shape in medium with Kerr nonlinearity to the analysis of femtosecond (fs) laser processing of dielectric in sub-critical (input power less than the critical power of selffocusing) regime. Simple analytical expressions are derived for the input beam power and spatial focusing parameter (numerical aperture) that are required for achieving an inscription threshold. Application of non-Gaussian laser beams for better controlled fs inscription at higher powers is also discussed. © 2007 Optical Society of America.

Extended Networks of Evolutionary Processors

This paper presents an extended behavior of networks of evolutionary processors. Usually, such nets are able to solve NP-complete problems working with symbolic information. Information can evolve applying rules and can be communicated though the net provided some constraints are verified. These nets are based on biological behavior of membrane systems, but transformed into a suitable computational model. Only symbolic information is communicated. This paper proposes to communicate evolution rules as well as symbolic information. This idea arises from the DNA structure in living cells, such DNA codes information and operations and it can be sent to other cells. Extended nets could be considered as a superset of networks of evolutionary processors since permitting and forbidden constraints can be written in order to deny rules communication.

Systemological Bases of Business Intelligence

Sustainable development support, balanced scorecard development and business process modeling are viewed from the position of systemology. Extensional, intentional and potential properties of a system are considered as necessary to satisfy functional requirements of a meta-system. The correspondence between extensional, intentional and potential properties of a system and sustainable, unsustainable, crisis and catastrophic states of a system is determined. The inaccessibility cause of the system mission is uncovered. The correspondence between extensional, intentional and potential properties of a system and balanced scorecard perspectives is showed. The IDEF0 function modeling method is checked against balanced scorecard perspectives. The correspondence between balanced scorecard perspectives and IDEF0 notations is considered.

The possibilities and limits of contestation in times of 'urban austerity'

This paper seeks to provide a conceptual framework in which to examine the social practices of contemporary austerity programmes in urban areas, including how these relate to different conceptions of crisis. Of current theoretical interest is the apparent ease with which these austerity measures have been accepted by urban governing agents. In order to advance these understandings we follow the recent post-structuralist discourse theory ‘logics’ approach of Glynos and Howarth (2007), focusing on the relationship between hegemony, political and social logics, and the subject whose identificatory practices are key to understanding the form, nature and stability of discursive settlements. In such thinking it is not only the formation of discourses and the mobilisation of rhetoric that are of interest, but also the manner in which the subjects of austerity identify with these. Through such an approach we examine the case of the regeneration/economic development and planning policy area in the city government of Birmingham (UK). In conclusion, we argue that the logics approach is a useful framework through which to examine how austerity has been uncontested in a city government, and the dynamics of acquiescence in relation to broader hegemonic discursive formations.

Viability Theory and Economic Modeling

A brief introduction into the theory of differential inclusions, viability theory and selections of set valued mappings is presented. As an application the implicit scheme of the Leontief dynamic input-output model is considered.

The mission and culture of the corporation

The economic crisis has brought a new situation also for the Hungarian economic policy, as neoliberalism as the main trend in economic thought is no longer valid. This phenomenon cannot be reduced to be a mere macroeconomic course shift, as an entire economic philosophy and approach has lost its relevance. One consequence of this is the need for a thorough revision of the theory and practice of business management, along with the re-evaluation of the notion and position of the corporation. Our study aims to contribute to this theoretical reformation, presenting that social values derived from psychological and sociological findings such as human motivational theories or trust are fundamental elements of the 21st century corporate model. To point to this, we use the ideological correspondences, while proving that our national research on corporate theory and even rather its application are far behind the 21st century requirements and lack even the Western view of the 20th century.

A beosztás és a nemek hatása a változások érzékelésére egy lean projekt tapasztalatai egy magyar autóipari beszállítónál (Efficient possibilities of the customer complaints: compensation and apology)

Tanulmányukban a szerzők egy magyar tulajdonú autóipari beszállító lean (továbbiakban karcsú) átalakulását vizsgáljuk. Bár az új rendszer bevezetése alig több mint egy éve kezdődött el a vállalatnál, mégis a rövid idő ellenére komoly eredményekről számolhatnak be. Különösen látványos a pénzügyi mutatók és a vevői elégedettség területén elért javulás. Kutatásuk célja kettős volt: (1) megvizsgálni, hogyan érzékelik a vezetők és a beosztottak a változásokat, valamint (2) összehasonlítani a vállalat két üzemében dolgozó nők és férfiak átalakítással kapcsolatos reakcióit és érzeteit. Az eredmények alapján elmondható, hogy a vezetők és a beosztottak, csakúgy, mint a két nem képviselői, nagyon eltérően gondolkodnak a változásokról és az átalakítás sikerének hátteréről. Eredményeik tükrében megállapítható, hogy a vizsgált szervezetnél a női munkavállalóknál a hit, a férfiaknál az elkötelezettség az a tényező, amely leginkább hatással van a sikerérzetre. A kutatás tapasztalatait felhasználva tanácsokat fogalmaznak meg a karcsú menedzsment sikeres bevezetésével kapcsolatosan. ______________ Relatively little research attention has been given to what happens after service failure, how the organizations respond to the failure and how this response affects customers’ subsequent behaviours and attitudes. This article proposes to take an in-depth look at the different organizational responses to customer complaints. On the basis of the equity theory the concept of justice has been used that involves distributive, procedural and interactional justice. Using 2x2x2 factorial design experiment based on scenarios the main findings of the research is that interactional justice (explanation and apology) is as important as distributive justice (compensation). On the other hand the result is dependent on the failure type: different recovery effort is efficient in the case of outcome or process failure.

A hatékony panaszkezelés lehetőségei: kompenzáció és bocsánatkérés (Efficient possibilities of the customer complaints: compensation and apology)

A szerzők cikkükben a panaszkezelés hatékonyságát vizsgálják, kutatási módszerük a szcenáriókon alapuló kísérleti módszertan. Eredményeik alapján elmondható, hogy a panaszkezelés hatásaként vizsgált elégedettség és lojalitás – előzetes hipotéziseiknek megfelelően – nemcsak a kompenzáció nagyságától függ, hanem lényeges az is, hogy a folyamat során milyen hangnemben történik a hiba kiigazítása. Elemzéseik azt is alátámasztják, hogy a hiba típusától is függ, hogy a kompenzáció vagy az őszinte bocsánatkérés-e a célravezetőbb. ____________ Relatively little research attention has been given to what happens after service failure, how the organizations respond to the failure and how this response affects customers’ subsequent behaviours and attitudes.

What is the Future of Strategic Management?

The history of planning and creating strategies has a past of over half a century. Throughout this lifetime period we have witnessed both the evolution of theory and practice. The MBA study books in the last-third of the 20th century have with predilection exhibited this very process as a complex of monetary centered budget planning, forecast-based planning, strategic planning and strategic management. There might be a controversy existing about the naming, characteristics and timing of these different sections but there is an accordance that the changes that we have taken place in the last decade as a whole without a doubt can be derived from these very changes in the business environment or in some outstanding cases (like 9/11) they can be acknowledged as the ability of corporate foreseeing and the ability to adapt to the vision of the future. The main purposes of the research is to provide a summarized picture about the changing process of this procedure during last decades as far as the planning and creating strategies are concerned and also their milestones and periods. Try to explore and systemize the very aspects of these changes. The happenings of the first decade of the new millennium are outstandingly interesting if we consider their real effect on the theory and practice of strategic management. Let us remember the euphoria around the year 2000, the predictions of „new technologies”, „new economy”, „new organization” and „new leadership”. We have implied before on the destruction of the twin towers of the World Trade Center which meant a new era, a new quality of international terrorism and its consequences (Afghanistan, Iraq). But the „product” of this decade is the strategic aim that companies focus on, which is the social responsibility regarding the unavoidance of the effects of climate change on the long run. During the research the big question has risen concerning how did the science of strategic management do as far as the predictions of the global monetary and economic crisis are concerned? And also its solutions this very science has to offer in order to handle and get over the crisis. Does it conclude from the answers given to the questions that a change in paradigms are necessary, a new quality is needed or may be we have come to a new crossroad of the development process that will take over strategic management?

Towards the formation of a sustainable South Florida: An analysis of conflict resolution and consensus building in the South Florida Everglades Ecosystem Restoration Initiative

This dissertation examines the sociological process of conflict resolution and consensus building in South Florida Everglades Ecosystem Restoration through what I define as a Network Management Coordinative Interstitial Group (NetMIG). The process of conflict resolution can be summarized as the participation of interested and affected parties (stakeholders) in a forum of negotiation. I study the case of the Governor's Commission for a Sustainable South Florida (GCSSF) that was established to reduce social conflict. Such conflict originated from environmental disputes about the Everglades and was manifested in the form of gridlock among regulatory (government) agencies, Indian tribes, as well as agricultural, environmental conservationist and urban development interests. The purpose of the participatory forum is to reduce conflicts of interest and to achieve consensus, with the ultimate goal of restoration of the original Everglades ecosystem, while cultivating the economic and cultural bases of the communities in the area. Further, the forum aim to formulate consensus through envisioning a common sustainable community by providing means to achieve a balance between human and natural systems. ^ Data were gathered using participant observation and document analysis techniques to conduct a theoretically based analysis of the role of the Network Management Coordinative Interstitial Group (NetMIG). I use conflict resolution theory, environmental conflict theory, stakeholder analysis, systems theory, differentiation and social change theory, and strategic management and planning theory. ^ The purpose of this study is to substantiate the role of the Governor's Commission for a Sustainable South Florida (GCSSF) as a consortium of organizations in an effort to resolve conflict rather than an ethnographic study of this organization. Environmental restoration of the Everglades is a vehicle for recognizing the significance of a Network Management Coordinative Interstitial Group (NetMIG), namely the Governor's Commission for a Sustainable South Florida (GCSSF), as a structural mechanism for stakeholder participation in the process of social conflict resolution through the creation of new cultural paradigms for a sustainable community. ^

The thermodynamics and statistical mechanics of protein folding

The physics of self-organization and complexity is manifested on a variety of biological scales, from large ecosystems to the molecular level. Protein molecules exhibit characteristics of complex systems in terms of their structure, dynamics, and function. Proteins have the extraordinary ability to fold to a specific functional three-dimensional shape, starting from a random coil, in a biologically relevant time. How they accomplish this is one of the secrets of life. In this work, theoretical research into understanding this remarkable behavior is discussed. Thermodynamic and statistical mechanical tools are used in order to investigate the protein folding dynamics and stability. Theoretical analyses of the results from computer simulation of the dynamics of a four-helix bundle show that the excluded volume entropic effects are very important in protein dynamics and crucial for protein stability. The dramatic effects of changing the size of sidechains imply that a strategic placement of amino acid residues with a particular size may be an important consideration in protein engineering. Another investigation deals with modeling protein structural transitions as a phase transition. Using finite size scaling theory, the nature of unfolding transition of a four-helix bundle protein was investigated and critical exponents for the transition were calculated for various hydrophobic strengths in the core. It is found that the order of the transition changes from first to higher order as the strength of the hydrophobic interaction in the core region is significantly increased. Finally, a detailed kinetic and thermodynamic analysis was carried out in a model two-helix bundle. The connection between the structural free-energy landscape and folding kinetics was quantified. I show how simple protein engineering, by changing the hydropathy of a small number of amino acids, can enhance protein folding by significantly changing the free energy landscape so that kinetic traps are removed. The results have general applicability in protein engineering as well as understanding the underlying physical mechanisms of protein folding. ^

Examining the process of regime change in the North Atlantic Treaty Organization: The divide between rhetoric and reality

The North Atlantic Treaty Organization (NATO) is a product of the Cold War through which its members organized their military forces for the purpose of collective defense against the common threat of Soviet-backed aggression. Employing the terminology of regime theory, the creation of NATO can be viewed as the introduction of an international security regime. Throughout the Cold War, NATO member states preserved their commitment to mutual defense while increasingly engaging in activities aimed at overcoming the division of Europe and promoting regional stability. The end of the Cold War has served as the catalyst for a new period of regime change as the Alliance introduced elements of a collective security regime by expanding its mandate to address new security challenges and reorganizing both its political and military organizational structures. ^ This research involves an interpretive analysis of NATO's evolution applying ideal theoretical constructs associated with distinct approaches to regime analysis. The process of regime change is investigated over several periods throughout the history of the Alliance in an effort to understand the Alliance's changing commitment to collective security. This research involves a review of regime theory literature, consisting of an examination of primary source documentation, including official documents and treaties, as well as a review of numerous secondary sources. This review is organized around a typology of power-based, organization-based, and norm-based approaches to regime analysis. This dissertation argues that the process of regime change within NATO is best understood by examining factors associated with multiple theoretical constructs. Relevant factors provide insights into the practice of collective security among NATO member states within Europe, while accounting for the inability of the NATO allies to build on the experience gained within Europe to play a more central role in operations outside of this region. This research contributes to a greater understanding of the nature of international regimes and the process of regime change, while offering recommendations aimed at increasing NATO's viability as a source of greater security and more meaningful international cooperation.^
