Social and organisational implications of CAD usage: a grounded theory in a fashion company

This paper focuses on the process of Computer Aided Design (CAD) diffusion into a group engaged in the development of innovative products. Adopting an ethnographic approach, we build a grounded theory for interpreting CAD usage in terms of the interplay between variables such as management orientation, training, actors' specialisation and deskilling, availability of shared archives, technological discontinuities between organisational areas.     

DS-optimal designs in one way ANOVA

Characterization and construction of optimal designs using the familiar optimality criteria, for example A-, D- and E-optimality are well studied in the literature. However the study of the Distance Optimality (DS-) criterion introduced by Sinha (1970) has very recently drawn attention of researchers. In the present article, we consider the singularly estimable full rank problem of estimating the full set of elementary treatment contrasts using the DS optimality criterion in the set up of a one way ANOVA model. Using a limit argument it turns out that a CRD in which difference between any two allocation numbers is at the most unity is uniquely DS-optimal. Acknowledgement. We are thankful to Prof. B. K. Sinha for suggesting the problem to us and many helpful discussions with him. We are also thankful to the referees for drawing our attention to the reference of Bischoff (1995) and many helpful comments.     

Executives’ Orientations as Indicators of Crisis Management Policies and Practices*

ABSTRACT The paper examines effects of executives’ orientations on crisis management awareness and practices, drawing on the simplicity and paradox management theories. It is suggested that a focus on single‐sided management constitutes an antecedent of crisis proneness. Employing a set of key corporate domains and based on a holistic organizational approach, the study aims at assessing the extent to which companies are crisis prone or prepared. In a sample of 82 Istaeli business and not‐for‐profit organizations it was found that human resource management, strategy, structure, and unlearning factors significantly predicted crisis preparedness. These results suggest that unlearning, despite a mere allusion to this correlate in the simplicity and paradox management theories, correlates better with crisis preparedness. By contrast, traditional strategy‐related and structural effects were marginally related to crisis management policies. Implications and suggestions for further research are proposed.     

How should charitable organisations motivate young professionals to give philanthropically?

One hundred and fifty‐eight bankers, accountants and corporate lawyers, aged under 40 years, earning more than £50,000 annually and working in the City of London were questioned about their attitudes and behaviour in relation to charitable giving. A conjoint analysis of the respondents' preferences revealed strong predilections for certain types of charitable organisation; for ‘social’ rewards in return for donating (invitations to gala events and black tie dinners for example); and for well‐known charities with established reputations. ‘Planned giving’ whereby donors receive tax breaks and other financial incentives to donate (as increasingly practised in the USA) did not represent a significant inducement to give so far as this particular sample was concerned. Overall the results suggest that young affluent male City employees constitute a distinct market segment for charity fundraisers, with unique characteristics that need to be addressed when developing donor products.

Testing the significance and the non-linearity of the Phillips trade-off in the Euro Area

This paper tests the significance and the non-linearity of the Phillips trade-off in the aggregate Euro Area, in an unobserved components model of stochastic NAIRU and trend output featuring the Phillips equation and the Okun law as main identifying equations, with quarterly data for 1970:I-2002:III. The Phillips curve turns out to be linear and its trade-off statistically significant, while non-linearity shows up in the Okun relation. The results prove to be robust to alternative lag length structures of the model, and to alternative non-linear functional forms. The trend-cycle decompositions estimated with the model capture the main features of the Euro Area’s recent macroeconomic record.First version received: 1 September 2003 / Final version received: June 2004CEMPRE - Centro de Estudos Macroeconómicos e Previsão - is supported by the Fundação para a Ciência e a Tecnologia, Portugal, through the Programa Operacional Ciência, Tecnologia e Inovação (POCTI) of the Quadro Comunitário de Apoio III, which is financed by FEDER and Portuguese funds.We thank comments on earlier versions by Fabio Canova, Miguel St Aubyn, Alvaro Almeida, Pete Richardson, Kevin Ross, and two anonymous referees.

Measuring financial risks with copulas

This paper is concerned with the statistical modeling of the dependence structure of multivariate financial data using the concept of copulas. We select some special copulas and identify the type of dependency captured by each one. We fit copulas to daily returns and simulate from the fitted models. We compare the effect of the choice of copula on risk measures and assess the variability of one-step-ahead predictions of portfolio losses. We analyze extreme scenarios and fit extreme value copulas to the block maxima and minima from daily returns. The stress scenarios constructed are compared to those obtained using models from the extreme value theory. We illustrate the usefulness of the copula approach using two stock market indexes.     

Incubation matters: Measuring the effect of business incubators on the innovation performance of start‐ups

This article explores the role of business incubators on the innovation performance of start‐ups; in addition, we also investigate how the incubation effect moderates other important factors driving their innovation performance. The empirical evidence comes from a sample of firms located in Northern Italy belonging to the manufacturing (mechanical engineering firms) and service sectors (knowledge‐intensive business services). The results suggest that the incubation effect is very important in shaping the innovation performance of new ventures (measured as a percentage of sales of new‐to‐market innovations). Moreover, it positively moderates the impact of (1) the internal technical capabilities and (2) the adoption of a limited portfolio of collaborations for innovation.     

The 2012 Olympic Ambassadors and sustainable tourism legacy

This paper examines the capacity of the London (2012) Olympic Ambassador volunteer programmes to create a sustainable tourism legacy. It contributes to the literature on event legacies, particularly the role of volunteers promoting tourism in their home destination. Using an exploratory inductive approach, semi-structured in-depth interviews were conducted, in 2012 and 2013, with managers of all 11 Ambassador volunteer programmes associated with London and the 10 other regional venues that hosted London Olympic and Paralympic Games events. These show that volunteer Ambassadors enhanced tourist experiences during the Games through the Ambassadors’ pride in their home city, enthusiasm and local knowledge. However, although the Ambassador programmes had aspirations to create a sustainable legacy, in the form of a pool of experienced volunteers to support future events and further tourist visits, this was severely constrained by cuts in local government budgets. The Government Olympic Executive provided a coordinating role leading up to the Games, but neither they nor the London Organising Committee for the Olympic Games provided practical assistance for legacy development. This was a missed opportunity to channel the enthusiasm of mega-event volunteers into further volunteering to promote tourism.     

Can teaching social dilemmas make people more prosocial? An experiment

Economics and business students regularly behave less prosocially than others. Can ethics training reverse this tendency? Results from a repeated public goods experiment reveal that it can. Students who attend an interactive lecture on social dilemmas show significantly more cooperation than others. However, the lecture does not appear to increase the incidence of reciprocal behavior. As many current social problems qualify as social dilemmas, this result stresses the importance of ethics training for policy makers and curriculum designers alike in overcoming the incentive structure of social dilemmas.     

Mix between Satisfaction and Attributes Destination Choice: A Segmentation Criterion to Understand the Ski Resorts Consumers

This study examined the attributes prioritized by tourists when choosing a winter sports destination and their degree of satisfaction with the services provided by Portugal's only ski resort. Two hundred tourists completed a questionnaire with factor analysis then deployed to extract the data that served as the basis for cluster analysis. Our results report discrepancies between the attributes valued by tourists when choosing winter sports destinations and their degree of satisfaction with the ski resort's services. Moreover, the combination between attributes/motivations prevailing in destination selection and the subsequent satisfaction with the services provided may generate information of relevance to evaluating organizational competitiveness.
