Strategic bidding in network constrained electricity markets using FAPSO
Authors: Bajpai Prabodh , Niwas Singh Sri 
Published: June 2008

PurposeThe purpose of this paper is to develop an optimal bidding strategy for a generation company (GenCo) in the network constrained electricity markets and to analyze the impact of network constraints and opponents bidding behavior on it.Design/methodology/approachA bi‐level programming (BLP) technique is formulated in which upper level problem represents an individual GenCo payoff maximization and the lower level represents the independent system operator's market clearing problem for minimizing customers' payments. The objective function of BLP problem used for bidding strategy by economic withholding is highly nonlinear, and there are complementarity terms to represent the market clearing. Fuzzy adaptive particle swarm optimization (FAPSO), which is a modern heuristic approach, is applied to obtain the global solution of the proposed BLP problem for single hourly and multi‐hourly market clearings. Opponents' bidding behavior is modeled with probabilistic estimation.FindingsIt is very difficult to obtain the global solution of this BLP problem using the deterministic approaches, even for a single hourly market clearing. However, the effectiveness of this new heuristic approach (FAPSO) has been established with four simulation cases on IEEE 30‐bus test system considering multi‐block bidding and multi‐hourly market clearings. The joint effect of network congestion and strategic bidding by opponents offer additional opportunities of increase in payoff of a GenCo.Practical implicationsFAPSO having dynamically adjusted particle swarm optimization inertia weight uses fuzzy evaluation to effectively follow the frequently changing conditions in the successive trading sessions of a real electricity market. This approach is applied to find the optimal bidding strategy of a GenCo competing with five GenCos in IEEE 30‐bus test system.Originality/valueThis paper is possibly the first attempt to evaluate an optimal bidding strategy for a GenCo through economic withholding in a network constrained electricity market using FAPSO.
The role of the sommeliers and their influence on US restaurant wine sales
Authors: Ben Dewald B.W.A. 
Published: June 2008

PurposeThe purpose of this paper is to examine how sommeliers influence wine sales in US restaurants and to understand how US restaurant sommeliers sell wine to customers, select for the wine list, and keep current on wines.Design/methodology/approachData from 250 telephone interviews among people at fine restaurants who were in charge of the selection and recommendation of wines for customers was reviewed. Fine restaurants were selected from wine spectator's “Gold Medal Winners” list and supplemented by Zagat's top 2,000 restaurants. The interviews averaged 29 minutes in length.FindingsOn an average, customers ask a sommelier to provide wine recommendations 38 per cent of the time and sommeliers volunteer wine recommendations 42 per cent of the time. While wine is becoming increasingly popular and consumers are more knowledgeable, sommeliers play an important role in identifying best products available to meet restaurant customers' expectations.Practical implicationsSommeliers play an important role in influencing the sale of wine in restaurants, in particular, in smaller restaurants and in fine dining restaurants. Focusing on value for money, winery reputation, type of variety and tracking customer preference are all critical factors that respondents considered when selecting wines and when recommending wines to customers.Originality/valueThis paper addresses the advantage of employing a sommelier in fine dining restaurants, given that when there is a designated sommelier more parties order wine (an average 76 per cent vs an average 70 per cent), the average check is higher ($62 vs $55) and the wine list is updated more frequently. Fine dining restaurant managers, owners and sommeliers will find value in this paper.
Market orientation of French and Hungarian small and medium‐sized wineries
Authors: Durrieu François , Toth Hofmeister Agnes 
Published: June 2008

PurposeThe purpose of this paper is to analyse the impact of market orientation on strategy orientation (communication, target and image strategy). This impact is studied by using a multicultural approach (Hungarian and French wineries).Design/methodology/approachA questionnaire was completed by 131 French wineries – châteaux and 66 Hungarian wineries. French wineries are located in the Bordeaux region. Participants were obtained by sending questionnaire to wineries lists provided by wine‐related organizations. Market orientation and strategy orientation scales were constructed by using confirmatory factor analysis and this impact confirmed by using structural equation modelling. To measure the differences of this impact between French and Hungarian wineries, multigroup analysis is practiced.FindingsMarket orientation as information gathering, and difficulties involved in searching and planning are defined. Concerning the impact of market orientation on strategy orientation, the main finding is that information gathering and planning impacts positively on the development of communication and target strategies; and the difficulties involved in searching for information impact positively on image strategy. Two main differences appear between French and Hungarian wineries: information gathering and difficulties in searching for information.Research limitations/implicationsOne main limit concerns the characteristics of Hungarian and French wineries that are not similar especially in terms of area size. So these cultural differences could be also explained by structural differences of the wineries.Practical implicationsThe majority of wineries do not have organized and large information gathering systems and marketing strategies are defined by communication objectives because they have some difficulties in defining their target.Originality/valueThe paper shows how image and communication strategies are implemented in Hungarian and French wineries.
An exploration of managerial expertise in the Western Australian wine industry
Authors: Charters Steve , Clark‐Murphy Marilyn , Davis Nicole , Brown Alan , Walker Elizabeth 
Published: June 2008

PurposeThe purpose of this paper is to identify the key management skills for running a successful winery business, which in the Australian industry is predominately a small to medium sized business, and explores the existence of such skills within the industry.Design/methodology/approachThe information was obtained through structured interviews with a range of winery owners and managers in the four main wine regions of Western Australia.FindingsWhilst a set of universal management skills are identified by the industry participants, these are not universally held. The study examines skills and training issues highlighting the diversity of winery owners and managers.Research limitations/implicationsThe study was conducted using qualitative methodology in one state of Australia only.Practical implicationsThe findings require further quantitative testing, but strongly imply that managerial skills in the wine industry are limited, and most managers are more focused on technical expertise than financial, strategic, marketing or HR planning and management.Originality/valueThe paper has benefit for the wine industry showing the strengths and weaknesses of its managers, and also for theorists who seek to understand management processes in a specific sector predominantly comprising small and medium sized enterprises.
Beyond the cluster: how wine drives regional economy to success
Authors: Larreina Mikel , Aguado Ricardo 
Published: June 2008

PurposeThis paper aims to analyse how the economic impact of wine in producing regions can be measured. It also seeks to show the relationship between wine cluster performance and regional economic development, through the study of Rioja's recent success in both wine market and distribution of wealth.Design/methodology/approachThe paper uses the input‐output analyses to estimate the economic impact of the wine cluster and its role in regional economy. The case of Rioja is taken as example of regions where wine is the driving economic force.FindingsThe paper finds that Rioja wine cluster specificities may be the cause of the recent outperformance of Riojan economy, in which the wine cluster accounts for a fifth of regional GDP. The increase in wine sales in this region is simultaneous to the spread of welfare among the local population.Originality/valueThe paper shows the extremely deep impact that changes in wine market may arise in wine producing regions' welfare, thus enabling wine sector's main actors to measure wine impact on regional economy.
Capital structure determinants: an empirical study of French companies in the wine industry
Authors: Viviani Jean‐Laurent 
Published: June 2008

PurposeThe purpose of this paper is to explain the leverage of French wine companies (410 companies) in the wine industry during the period 2000‐2004.Design/methodology/approachDifferent classical capital structure theories are reviewed (trade‐off theory (TOT), pecking order theory (POT) and dynamic TOT) in order to formulate testable propositions concerning the determinants of debt levels of the French wine companies. A number of regression models (classical and panel techniques) are developed to test the static theory of trade‐off against the POT.FindingsThe results suggest that POT seems to better explain leverage of French wine companies. Significant differences in debt ratio were found between cooperatives and other legal structures. Debt ratios are also different between sub‐sectors (wholesalers, wine growers, wine makers, etc.).Practical implicationsCost of capital is one of the pillars of competitive advantage (or disadvantage) of companies. With the objective to minimize the cost of capital, it seems very important to know the potential determinants of an optimal capital structure.Originality/valueThis is a first study of capital structure determinants in the French wine industry which contributes to the current debate between competitive capital structure theories.
Doing management history: one editor's views
Authors: van Fleet David D. 
Published: June 2008

PurposeCurrently, only a small number of manuscripts dealing with management history are being submitted to journals, and few of those are being accepted for publication. What is needed to change this situation is more high‐quality research that is more interesting to a wider audience. The purpose of this paper is to offer some suggestions for overcoming current deficiencies.Design/methodology/approachThe perspective of one editor about what is being done and what might be done in terms of publishing management history research is presented.FindingsThe unique perspective of an individual who is a past editor of a major management journal and current editor of an online journal each of which has published a variety of management history articles is presented.Originality/valueThe paper stresses that too few management history manuscripts submitted to journals are of high‐enough quality or sufficiently interesting to merit publication and that more good quality research that is interesting to a wider audience is needed. The paper offers suggestions to management history scholars as a means of changing this situation.
W.O. Carpenter and the California Gold Rush: the making of entrepreneurial opportunities
Authors: Fleischman Gary M. , Kidwell Roland E. , Achey Kidwell Linda 
Published: June 2008

PurposeThe purpose of this paper is to trace the entrepreneurial opportunity identification process of William Oscar Carpenter (WOC), a nineteenth century farmer, who went to California in 1850 to make his fortune in gold mining and ended up starting several new business ventures. The paper seeks to recount WOC's experiences and then apply them to similar issues faced by entrepreneurs in a modern‐day developing economy.Design/methodology/approachUsing qualitative inquiry through archival research, the paper examines a compilation of WOC's letters to his future wife in New York. The letters provide a detailed account of the hardships and poor living conditions faced by gold seekers. The letters are examined and interpreted in the context of opportunity identification and the California Gold Rush, then applied to contemporary entrepreneurs.FindingsWOC's letters elucidate the difficulties encountered making the trip from the East Coast to California, give later generations an historical viewpoint on a variety of social issues, and detail WOC's entrepreneurial activities in California. After a brief period as a successful miner, WOC's business career developed and branched out in different directions as he perceived entrepreneurial opportunities associated with the California Gold Rush. His story is an excellent example of opportunity recognition that has implications for current entrepreneurial activity.Originality/valueWOC's awareness, anticipation, and timely action regarding business opportunity can be related, compared and contrasted with entrepreneurial activity today. The paper discusses these implications in light of opportunity recognition research and developing entrepreneurial economies.
Fifty years of influence in the workplace
Authors: Elias Steven 
Published: June 2008

PurposeWhile focusing on the renowned bases of social power put forth by French and Raven in 1959, this paper aims to address the history and future of this taxonomy within organizational settings. Topics include the evolution of the power taxonomy, the power/interaction model, and matters relevant to future research and practice.Design/methodology/approachFirst, a historical overview of the French and Raven power taxonomy is provided. Second, ways in which the taxonomy has been updated over the past several decades are discussed. Third, an overview of Raven's power/interaction model (1993) is presented. Lastly, implications for future research and practice within organizations are offered.FindingsA review of the historic and contemporary writings dedicated to social power would indicate that the advances made to the original French and Raven power taxonomy have not been incorporated into the management and organizational behavior literatures.Practical implicationsPractitioners and scholars interested in issues related to influence in organizational settings would benefit from an understanding of the historical developments that have occurred to the power taxonomy over the past half‐century, as well as the formation of the power/interaction model.Originality/valueThis paper provides readers with a historical overview of the development of the French and Raven social power taxonomy, in addition to addressing the field's more recent developments. As such, the paper will be of value to anyone interested in influence within organizational settings.
An historical perspective on the Sarbanes‐Oxley Act
Authors: Govekar Paul L. 
Published: June 2008

PurposeThe purpose of this paper is to provide an historical perspective to help understand the forces that resulted in the Sarbanes‐Oxley Act. It aims to provide an historical vindication of the taxonomy developed by Charles Conrad in 2003.Design/methodology/approachThe paper applies a framework developed by Charles Conrad in 2003 to explain the events that led to the corporate meltdown in 2002‐2003 and compare it to a similar scandal in the insurance industry at the beginning of the twentieth century.FindingsA number of parallels were found between the two incidents. Additionally, the framework developed by Charles Conrad in 2003 was vindicated by the historical comparison. Lessons for practicing managers, domestic and international, are presented along with avenues for possible future research.Practical implicationsRecent changes in the political landscape, particularly in the USA, may indicate that Sarbanes‐Oxley will, indeed, be with us for a longer, rather shorter time. However, the real lesson for managers and scholars of management may be to concentrate on the three trends that foreshadow scandals and meltdowns to prevent similar problems, with their inevitable legal backlash in the future.Originality/valueThis paper uses the framework developed by Charles Conrad in 2003 to explore to different corporate meltdowns separated by a century in the USA. Lessons learned from these incidents as well as a perspective on the probable effective life of the Sarbanes‐Oxley Act are suggested.
The Fred Taylor baseball myth: a son goes to bat for his father
Authors: Taylor Shannon G. , Bedeian Arthur G. 
Published: June 2008

PurposeThe purpose of this paper is to refute allegations from various sources that, as a pitcher for the Phillips Exeter Academy baseball team, Frederick W. Taylor cheated by using an illegal overhand delivery.Design/methodology/approachDrawing on archival research, including a recently discovered letter by his son, Robert, this paper dispels the “myth” surrounding Taylor's alleged cheating as a member of the Phillips Exeter Academy baseball team.FindingsThis research suggests that the “myth” of Fred's purported cheating may be traced to a January 1934 Esquire Magazine article by American Novelist John R. Dos Passos.Originality/valueAs a consequence, of the information only a son could have provided, this paper sets the record straight concerning Taylor's alleged cheating, and in doing so, demonstrate how a reliance on “myth” rather than “fact” stands in the way of capturing the elusive past.
F.W. Taylor's lecture on management, June 4, 1907: an introduction
Authors: Wrege Charles D. 
Published: June 2008

PurposeThe purpose of this paper is to introduce Frederick W. Taylor's lecture on his “task” system of management, given at his home in “Boxley” in 1907.Design/methodology/approachThe paper summarizes the lecture's contents, and details its background.FindingsThe paper emphasizes the critical importance of primary sources to the work of management scholars, not just management history.Originality/valueThe paper provides further evidence of the import that needs to be attached to sound historical method as a basis for scholarship in management in general, and management history, in particular.
Report of a lecture by and questions put to Mr F.W. Taylor: a transcript
Authors: Taylor F.W. 
Published: June 2008

PurposeThe purpose of this paper is to provide a transcript of Fredrick W. Taylor's 1907 lecture on his “task” system of management.Design/methodology/approachThe paper shows its advantages over traditional personal initiative styles, suggesting that managers should not allow employees to think for themselves but make sure they simply carry out tasks as instructed. Demonstrated this by using as an example pig‐iron handlers at Bethlehem Steel Company. Relates how he established scientific principles to ascertain the maximum load a man could carry and the optimum wage.FindingsInstead of asking if workers felt able to move heavier loads, by telling them he only employed “high‐priced men”, he found plenty of willing employees.Originality/valueThe paper offers an example of how primary sources can be of critical importance to management scholars, not just management historians.
The association of worker productivity and mental health: a review of the literature
Authors: Burton Wayne N. , Schultz Alyssa B. , Chen Chin‐Yu , Edington Dee W. 
Published: June 2008

PurposeDepression and other mental health disorders have a large impact on the quality of life and productivity of millions of individuals worldwide. For employers, mental health disorders are associated with increased health care costs as well as productivity losses in the form of absenteeism, short‐term disability absences and reduced on‐the‐job productivity‐known as presenteeism. The purpose of this paper is to review the association of worker productivity and mental health.Design/methodology/approachThis review summarizes the literature on the prevalence of mental health conditions among working adults, and the association between these disorders and productivity. Finally, the impact of interventions or workplace policies on the productivity of those suffering with mental health conditions is covered and recommendations for employers are suggested.FindingsDepressive disorders are relatively common in most workforces compared to other mental health conditions. The majority of studies on mental health and productivity have been conducted as part of nationwide surveys or in patient populations rather than worksites. The majority of studies show associations between mental health conditions and absenteeism (particularly short‐term disability absences). When presenteeism is measured by a validated questionnaire, results show that depression significantly impacts on‐the‐job productivity (presenteeism). Studies also indicate that the treatment expenditures for employees with depression may be offset by reductions in absenteeism, disability and on the job productivity losses.Originality/valueWorkplace policies and benefits which support employees suffering with mental health disorders and provide access to evidenced‐based care adhering to best practice guidelines may improve the quality of life of employees and lead to reduced absenteeism, disability and lost productivity.
Employer integration of health promotion and health protection programs
Authors: Goetzel Ron Z. , Ozminkowski Ronald J. , Bowen Jennie , Tabrizi Maryam J. 
Published: June 2008

PurposeThe paper seeks to describe the evolution of an integrated approach to health and productivity management that combines the disciplines of worksite health promotion and occupational safety and health, and to offer advice on how to implement such an integrated approach.Design/methodology/approachThe paper takes the form of a review of the literature, focusing on the psychological, organizational, and human capital models that must be integrated for successful health and productivity management.FindingsThe first integrated health, safety, and productivity model was presented by DeJoy and Southern in 1993. However, occupational safety and health and worksite health promotion professionals view the workplace in different ways (from psychological and public health orientations, respectively) that may result in siloed work environments. Better communication and collaboration across these disciplines is essential for success. That can be fostered by adopting a human capital framework that views the health and safety of employees as essential ingredients for a healthy and productive work force. A practical approach for successful health and productivity management uses integrated data to investigate where challenges to worker health and safety can be found. This is followed by strategic and tactical planning to address these challenges. Programs that address problems at all levels (individual, organizational, environmental) are then adopted, followed by formal, rigorous, and continuous monitoring and evaluation.Originality/valueThe concept of integrated health and productivity management is new but is now being adopted by many organizations. Worksite health promotion and occupational safety and health professionals can work together to make substantial improvements to the quality of employees' lives and the economic and social health of the organizations where they practice.
