Visitors’ acceptance of negative ecological impacts in national parks: comparing the explanatory power of psychographic scales in a Norwegian mountain setting

Even in protected areas, it is inevitable that any human use will produce some impact on natural resources. This study identifies visitors’ tolerance of potential negative ecological impacts from tourism activities and facilities in a Norwegian national park context, based on park visitors’ expressed degree of acceptance of negative effects on particular species of wildlife (wild reindeer and raptors) and on vegetation. Attitudes were analysed using psychographic scales, reflecting respondents’ nature orientations, their specific facility desires, their preferences in a wilderness setting and their concerns about human interaction with the natural environment. Fourteen research hypotheses were tested. Findings demonstrated that the psychographic scales explained more variation in attitudes than most social background and trip characteristics. Higher levels of education among visitors were strongly associated with increased ecological concern; age and gender were not. There was generally strong ecological awareness and eco-centrism among park visitors in general, with a small proportion of wilderness purists. Better trail conditions, signposting and interpretation were sought. But park visitors were also found to possess a complex mixture of needs and drivers. The study found significant potential for strategic alliances between tourism and conservation interests, and key value issues for park governance systems.     

Expatriate or local bosses? HCN subordinates' preferences in leadership behaviour

This article explores host-country national subordinates’ preferences in leadership behaviour comparing expatriate bosses and local bosses. From a sample of 240 middle managers in Hong Kong with experience with both local Chinese bosses and expatriate bosses from a broad spectrum of Western and Asian countries, it was found that the subordinate managers assessed the leadership behaviour of their expatriate bosses to be significantly closer to that of their perceived ideal boss. American leadership behaviour was the most preferred and Japanese leader style was the least preferred, with British leadership style comprising a middle group. Implications of these findings for international business firms and future academic research are discussed.     

MULTIVARIATE METHODS FOR MONITORING STRUCTURAL CHANGE

Detection of structural change is a critical empirical activity, but continuous ‘monitoring’ for changes in real time raises well‐known econometric issues that have been explored in a single series context. If multiple series co‐break then it is possible that simultaneous examination of a set of series helps identify changes with higher probability or more rapidly than when series are examined on a case‐by‐case basis. Some asymptotic theory is developed for maximum and average CUSUM detection tests. Monte Carlo experiments suggest that these both provide an improvement in detection relative to a univariate detector over a wide range of experimental parameters, given a sufficiently large number of co‐breaking series. This is robust to a cross‐sectional correlation in the errors (a factor structure) and heterogeneity in the break dates. We apply the test to a panel of UK price indices.

The System of Rice Intensification (SRI): a challenge for science,and an opportunity for farmer empowerment towards sustainable agriculture

Increasing demand for cereals produced from limited natural resources stimulated the Green Revolution in grain crops like wheat and rice. But the gap between potential and actual production continues. Concerns about sustainability, and the social and technical shortcomings of the Green Revolution, have triggered a number of alternative crop production strategies. One, in particular, the so-called System of Rice Intensification (SRI), is attracting attention by governments, civil society organizations and farmers in Asia and elsewhere.     

Beyond the world of packaged goods: assessing the relevance of integrated marketing communications for retail and consumer service marketing

Product and packaged goods marketers have responded to changing consumer and media environments by adopting integrated approaches to marketing communication. The value and utility of such approaches likely extend to a wide range of marketers, but there have been few published attempts to examine the viability of the integrated marketing communication concept in retail and service marketing. This study addresses this void by using a seven-stage model of integrated marketing communications to examine the media and message delivery practices of national and regional retailers and consumer service marketers. The results of a national mail survey found many of these marketers using such key integrated marketing communication elements as multiple media, databases, individual-level consumer information and behavioural response measures in their media and message delivery practices. Few, however, were using these elements in a strategic or coordinated fashion. Integrated approaches thus appear to have much value in retail and service marketing, particularly as a means for coordinating media and message delivery elements in a fashion that provides a way to link behavioural responses to media vehicles and advertising messages.     

The value contribution of strategic foresight: Insights from an empirical study of large European companies

This paper focuses on exploring the potential and empirically observable value creation of strategic foresight activities in firms. We first review the literature on strategic foresight, innovation management and strategic management in order to identify the potential value contributions. We use survey data from 77 large multinational firms to assess how much value is generated from formalized strategic foresight practices in these firms. We show that it is possible to capture value through (1) an enhanced capacity to perceive change, (2) an enhanced capacity to interpret and respond to change, (3) influencing other actors, (4) and through an enhanced capacity for organizational learning.
