New concepts of the power received by ideal energy storage elements: the instantaneous complex power approach

This paper presents some definitions and concepts of the Instantaneous Complex Power Theory [1] which is a new approach for the Akagi's Instantaneous Reactive Power Theory [2].The powers received by an ideal inductor are interpreted and the knowledge of the actual nature of these powers may lead to changes of the conventional electrical power concepts.

Essays On CEO Compensation: New Evidence On The Managerial-Power Vs. Optimal Contracting Debate

This dissertation analyzes the effect of market analysts’ expectations of share prices (price targets) on executive compensation. It examines how well the estimated effects of price targets on compensation fit with two competing views on determining executive compensation: the arm’s length bargaining model, which assumes that a board seeks to maximize shareholders’ interests, and the managerial power model, which assumes that a board seeks to maximize managers’ compensation (Bebchuk et al. 2005). The first chapter documents the pattern of CEO pay from fiscal year 1996 to 2010. The second chapter analyzes the Institutional Broker Estimate System Detail History Price Target data file, which that reports analysts’ price targets for firms. I show that the number of price target announcements is positively associated with company share price’s volatility, that price targets are predictive of changes in the value of stocks, and that when analysts announce positive (negative) expectations of future stock price, share prices change in the same direction in the short run. The third chapter analyzes the effect of price targets on executive compensation. I find that analysts' price targets alter the composition of executive pay between cash-based compensation and stock-based compensation. When analysts forecast a rise (fall) in the share price for a firm, the compensation package tilts toward stock-based (cash-based) compensation. The substitution effect is stronger in companies that have weaker corporate governance. The fourth chapter explores the effect of the introduction of the Sarbanes-Oxley Act (SOX) in 2002 and its reinforcement in 2006 on the options granting process. I show that the introduction of SOX and its reinforcement eliminated the practice of backdating options but increased “spring-loading” of option grants around price targets announcements. Overall, the dissertation shows that price targets provide insights into the determinants of executive pay in favor of the managerial power model.

Strategic information systems at the Colombian President's Office (1990-1992) : a managerial cybernetic approach

This research studies the issue of using strategic information technology for improving organisational effectiveness. It analyses different academic approaches explaining the nature of information systems and the need organisations feel of developing strategic information systems planning processes, to improve organisational effectiveness. It chooses Managerial Cybernetics as the theoretical foundation supporting development of a "Strategic Information Systems Planning" Framework, and uses it for supporting the analysis of a documented story about the process lived by the Colombian President's Office, in 1990-1992. It argues that by analysing the situation through this new analysis framework we may enlighten some previously unclear situations lived, and not yet properly explained through other approaches to strategic information systems planning. The documented history explains the organisational context and strategic postures of the Colombian President's Office and the Colombian Public Sector, at that time, as well as some of the strategic information systems defined and developed. In particular it analyses a system developed jointly by the President's Office and the National Planning Department, for measuring results of the main national development programmes. Then, it reviews these situations, in the light of the new framework and presents the main findings of the exercise. Finally, it analyses the whole research exercise, the perceived usefulness of the chosen frameworks and tools to enlighten the real situations analysed that were not clear enough, and some open research paths to follow for future researchers interested in the issue.

Hur påverkar ägarbilden hos svenska företag den rörliga ersättningen till den verkställande direktören?

Bakgrund Det diskuteras mycket idag om ersättningar till verkställande direktörer (Vd) och storleken på dessa. Många har synpunkter på den enligt dem väldigt höga ersättningen och framförallt är många kritiska till de stora bonusar som tilldelas till företagsledare. Samtidigt är det ägarna som genom representation i styrelse och på bolagstämma bestämmer ersättningen. Syfte Syftet med studien är att undersöka om det föreligger ett samband mellan ägarbilden och andel rörlig lön till den verkställande direktören. Metod I studien tillämpas en deduktiv forskningsansats där vi utgått från existerande teorier och tidigare empirisk forskning för att skapa en hypotes som sedan kan bekräftas eller förkastas. Hypotesen testas genom en kvantitativ metod där data samlats in över 56 stycken svenska bolag för att sedan testas med statistisk regressionsanalys. Slutsats Undersökningen visar att det finns ett negativt samband mellan ett större ägande och andel rörlig ersättning till verkställande direktör.

A model of gender prejudice, power, and discrimination: How hierarchy-enhancing factors predominate over hierarchy-attenuating factors

Gender inequalities remain an issue in our society and particularly in the workplace. Several factors can explain this gender difference in top-level managerial positions such as career ambitions but also biases against women. In our chapter, we propose a model explaining why gender inequalities and particularly discrimination against women is still present in our societies despite social norms and existing legislation on gender equality. To this purpose, we review research on discrimination through two different approaches, (a) a prejudice approach through the justification-suppression model developed by Crandall and Eshleman (2003) and (b) a power approach through the social dominance theory (Pratto, Sidanius, Stallworth, & Malle, 1994; Sidanius & Pratto, 1999). In our work, we integrate these two approaches and propose a model of gender prejudice, power and discrimination. The integration of these two approaches contributes to a better understanding of how discrimination against women is formed and maintained over time.

Emotional Intelligence As A Determinant Of Conflict Style Adoption Of Managers: A Theoretical Perspective

Successful management is dependent heavily on the manager’s ability to handle conflict effectively. The workforce has been increasingly becoming diversified vis-à-vis the gender, culture and ethnicity. The present work environment has in itself contributed to sowing seeds of conflict with greater diversity, hostility, complexity and newer business competencies in the work context.The classic study of Mintzberg’s Managerial roles approach (1973) also says that a manager has to spend sufficient time and energy in solving conflict as he has to take roles as a negotiator, and dispute handler. An understanding of the conflict and role that it plays in influencing employee behavior constructively or destructively is immense. Therefore conflict when left unmanaged can lead to diminished cohesiveness amongst employees, productivity and reduced organizational fitness. To manage conflict effective conflict resolution strategies that have constructive outcomes is called for. Conflict resolution style theorists opine that collaborative or integrative style, where there is high concern for task and people is considered to give positive individual and organizational outcomes, while the withdrawing /avoidance style and forcing / dominating style are considered to be ineffective in managing conflict. Though managers have typical preferences in the styles followed it need not necessarily be the typical response as it depends on the context, power relationships, emotions etc. The adoption of conflict styles of managers however is dependent on variables like gender orientation, cultural values, personality orientation, underlying relationships – public/private. The paper attempts to draw the importance of managing conflicts at workplace positively and the need for effective conflict resolution strategies. The conflict style adopted and the variables that affect the adoption of each style are discussed and possible interventions at the workplace are suggested

New perspectives on the governance of executive compensation:an examination of the role and effect of compensation consultants

We develop a multi-theoretic approach, drawing on economic, institutional, managerial power and social comparison literatures to explain the role of the external compensation consultant in the top management pay setting institutional field. Taking advantage of recent disclosure requirements in the UK, we collect data on compensation consultant use in 232 large companies. We show that consultants are a prevalent part of the CEO pay setting scene, and document evidence of all advisor use. Our econometric results show that consultant use is associated with firm size and the equity pay mix. We also show that CEO pay is positively associated with peer firms that share consultants, with higher board and consultant interlocks, and some evidence that where firms supply other business services to the firm, CEO pay is greater. © 2009 Springer Science+Business Media, LLC.

Asiakasomisteisten osuuskauppojen omistajaohjauksen erityispiirteistä ja haasteista

Omistajalähtöisen kulttuurin voimistumisen myötä omistajaohjausjärjestelmät ovat nousseet merkittävään asemaan yritysten toiminnassa. Tämä tutkielma osallistuu omistajaohjauksesta käytävään akateemiseen ja liikkeenjohdolliseen keskusteluun. Tutkimuksen tavoitteena on kuvata ja ymmärtää asiakasomisteisten osuuskauppojen omistajaohjaukseen liittyviä erityispiirteitä ja haasteita. Tutkimuksen tavoitteisiin pyritään vastaamaan analysoimalla tutkimusta varten kerättyä S-ryhmän alueosuuskauppojen hallintoneuvostojen puheenjohtajien haastatteluista (22 kpl) ja S-ryhmän julkaisemasta kirjallisesta materiaalista koostuvaa laadullista aineistoa. Tutkimuksen mukaan osuuskauppojen omistajaohjaus poikkeaa sijoittajaomisteisten yritysten omistajaohjauksesta paitsi hallintotapaan, rahoitukseen ja omistusoikeuksiin liittyvissä kysymyksissä, myös siinä, että osuuskaupoissa omistajakunta on passiivista, eikä aina edes tiedosta omistajuuttaan. Haasteita osuuskauppojen omistajaohjaukseen tuovat luottamushenkilöiden edustavuuteen ja osaamistasoon, tiedonkulkuun, omistajien lyhyen ja pitkän tähtäimen etujen tasapainottamiseen sekä liikkeenjohdon vallan korostumiseen liittyvät tekijät.

Designed Extension of Survival Studies: Application to Clinical Trials with Unrecognized Heterogeneity

It is well known that unrecognized heterogeneity among patients, such as is conferred by genetic subtype, can undermine the power of randomized trial, designed under the assumption of homogeneity, to detect a truly beneficial treatment. We consider the conditional power approach to allow for recovery of power under unexplained heterogeneity. While Proschan and Hunsberger (1995) confined the application of conditional power design to normally distributed observations, we consider more general and difficult settings in which the data are in the framework of continuous time and are subject to censoring. In particular, we derive a procedure appropriate for the analysis of the weighted log rank test under the assumption of a proportional hazards frailty model. The proposed method is illustrated through application to a brain tumor trial.

The European Union and global governance:a handbook

The role of the European Union in global politics has been of growing interest over the past decade. The EU is a key player in global institutions such as the World Trade Organization (WTO) and NATO. It continues to construct an emerging identity and project its values and interests throughout contemporary international relations. The capacity of the EU to both formulate and realise its goals, however, remains contested. Some scholars claim the EU’s `soft power’ attitude rivals that of the USA’s `hard power’ approach to international relations. Others view the EU as insufficiently able to produce a co-ordinated position to project upon global politics. Regardless of the position taken within this debate, the EU’s relationship with its external partners has an increasingly important impact upon economic, political and security concerns on an international level. Trade negotiations, military interventions, democracy promotion, international development and responses to the global economic crisis have all witnessed the EU playing a central role. This has seen the EU become both a major force in contemporary institutions of global governance and a template for supranational governance that might influence other attempts to construct regional and global institutions. This volume brings together a collection of leading EU scholars to provide a state-of-the-art overview covering these and other debates relating to the EU’s role in contemporary global governance. The Handbook is divided into four main sections: Part I: European studies and global governance – provides an overview and critical assessment of the leading theoretical approaches through which the EU’s role in global governance has been addressed within the literature. Part II: Institutions – examines the role played by the key EU institutions in pursuing a role for the EU in contemporary international relations. Part III: Policy and issue areas – explores developments within particular policy sectors, assessing the different impact that the EU has had in different issue areas, including foreign and security policy, environmental policy, common commercial policy, the Common Agricultural Policy, development policy, accession policy, the Neighbourhood Policy and conflict transformation. Part IV: The global multilevel governance complex and the EU – focuses on the relationship between the EU and the institutions, regions and countries with which it forms a global multilevel governance complex, including chapters on the EU’s relationship with the WTO, United Nations, East Asia, Africa and the USA.

Introduction

The role of the European Union in global politics has been of growing interest over the past decade. The EU is a key player in global institutions such as the World Trade Organization (WTO) and NATO. It continues to construct an emerging identity and project its values and interests throughout contemporary international relations. The capacity of the EU to both formulate and realise its goals, however, remains contested. Some scholars claim the EU’s `soft power’ attitude rivals that of the USA’s `hard power’ approach to international relations. Others view the EU as insufficiently able to produce a co-ordinated position to project upon global politics. Regardless of the position taken within this debate, the EU’s relationship with its external partners has an increasingly important impact upon economic, political and security concerns on an international level. Trade negotiations, military interventions, democracy promotion, international development and responses to the global economic crisis have all witnessed the EU playing a central role.
