Perspectives on Gerhard: Selected Proceedings of the 2nd and 3rd International Roberto Gerhard Conferences

Perspectives on Gerhard expands several papers given at the 2nd and 3rd International Roberto Gerhard Conferences in 2012 and 2013. The book focuses on two aspects of Gerhard. Firstly, the pre-1939 period in which he was a student of Schoenberg and then, on returning to Catalonia, began to establish a reputation as a composer. Secondly, and more generally on the composer's stylistic and aesthetic evolution. This latter focus includes both Gerhard's approach to serialism both harmonically and melodically as well as the pivotal role the USA was to play in his later life. The book concludes with two personal reminiscences given at the conferences by Ferran Gerhard and Mariona Agustí Badia

The History Boys::Critical reflections on our contributions to management learning and their ongoing implications

In this reflective essay, written for the 50th anniversary of Management Learning, we look at the history of the journal from a unique vantage point, our interconnected, academic lived experience of publishing in the journal. Our aim is to undertake an historical review of our publications in Management Learning in order to identify the key themes of our work, to make connections with broader academic and social events of the time and to assert the continuing relevance of these themes for future scholarship. We review 27 papers that we have published in Management Learning since Volume 1 (1971) and identify four main themes from our papers. These are set in the context of the development of critical management education. We highlight the broader dimensions to our themes and suggest two areas with implications for future scholarship in Management Learning. In our conclusion, we use our findings and reflections to identify what we have learned about management learning, as well as making a call for action in relation to what we are labelling historical reflexivity

Mitigating Anxiety:The role of strategic leadership groups during radical organisational change

This paper examines the role of strategic leadership groups in radical organizational change. Previous research has focused on how ‘heroic’ individual leaders guide change. In contrast, we argue that strategic leadership groups are indispensable to understanding and supporting radical organizational change. Building on a longitudinal study in a global European company, our research identifies four phases of ‘negotiated order’ that shape group and organisational responses to change. Our findings reveal that strategic leadership groups help with the management of emotions, and with understanding the shifting authority relations that inevitably arise during periods of change. Drawing upon the psychoanalytic concept of ‘projective identification’, we develop a theoretical framework for understanding the tensions of change. The model shows how emotional coalitions that develop in strategic leadership groups afford a source of political and psychological containment against the anxieties of radical organisational change. These formations offer transitional spaces for change, providing opportunities for progress. The advantage of this new perspective on radical change is that it helps to move the organization beyond periods of ambivalence and conflict, with positive implications for leadership practice.Peer reviewe

Asymmetric Price Adjustment: Are IPO Prices too "Sticky"?

The study of IPO mispricing is salient because it raises important questions concerning market efficiency and the existence of systematic stock patterns that can be employed by investors to generate excess market returns. The purpose of this paper is to investigate the informational efficiency of IPO market prices with respect to the first 3 trading day’s return and to examine the effect of varying investor sentiment on this information efficiency.  Under traditional definitions of market efficiency, asset prices, including IPO prices should fully reflect all available and relevant information (Fama 1970).  An increasing body of empirical evidence, however, suggests that IPO prices are not efficient as evidenced both in the short run and the long run.  The speed of incorporation of new information into stock prices is critical to many central issues in financial research, such as market efficiency, arbitrage, and market structure. This paper analyzes the speed of price adjustment to information events for IPOs. The setting of the immediate aftermarket presents an opportunity to investigate the issue when little or no trading history exists. In such a setting, investors are more exposed to new information because they cannot observe the stock price behavior or the reactions to previous information signals

Shift factor-based SCOPF topology control MIP formulations with substation configurations

Topology control (TC) is an effective tool for managing congestion, contingency events, and overload control. The majority of TC research has focused on line and transformer switching. Substation reconfiguration is an additional TC action, which consists of opening or closing breakers not in series with lines or transformers. Some reconfiguration actions can be simpler to implement than branch opening, seen as a less invasive action. This paper introduces two formulations that incorporate substation reconfiguration with branch opening in a unified TC framework. The first method starts from a topology with all candidate breakers open, and breaker closing is emulated and optimized using virtual transactions. The second method takes the opposite approach, starting from a fully closed topology and optimizing breaker openings. We provide a theoretical framework for both methods and formulate security-constrained shift factor MIP TC formulations that incorporate both breaker and branch switching. By maintaining the shift factor formulation, we take advantage of its compactness, especially in the context of contingency constraints, and by focusing on reconfiguring substations, we hope to provide system operators additional flexibility in their TC decision processes. Simulation results on a subarea of PJM illustrate the application of the two formulations to realistic systems.The work was supported in part by the Advanced Research Projects Agency-Energy, U.S. Department of Energy, under Grant DE-AR0000223 and in part by the U.S. National Science Foundation Emerging Frontiers in Research and Innovation under Grant 1038230.
