Exploring the role of expedition staff in volunteer tourism

Conservation volunteer tourism (VT) (or nature conservation expedition)‐related organisations can provide a meeting point for both tourists and field‐based scientists. Expedition leaders should be aware of the needs of the volunteer tourists that can be fulfilled through VT. It appears that the role of expedition leaders is central to the successful execution of the VT expedition. This study aimed to understand the expedition leaders' perceptions of VT, their perspective of the expectations of their volunteer tourists and their requirements of the volunteers, and assess how volunteers perform with regard to those requirements. The results suggest that there may be some differences in perceptions between leaders and volunteer tourists that may affect the success of the expedition.

Public Debt,Economic Growth and Inflation in African Economies

We analyse the relationship between public debt, economic growth and inflation in a group of 52 African economies between 1950 and 2012. The results indicate that the limits of public debt are negatively related to economic growth and exhibit, from a given level of debt, an inverted U behaviour regarding the relationship between economic growth and public debt. Briefly, the high levels of public debt are coincident with reduced rates of economic growth and rising levels of inflation. Our results for three specific geographical areas resemble those of the overall analysis, despite some differences. In North African countries, the growth rates of the gross domestic product (GDP) and inflation also show an inverted U behaviour as the ratio of public debt/GDP increases. The highest rate of economic growth is recorded when the ratio of public debt/GDP is below 30% of GDP and corresponds to an average inflation rate of 5.33%. An identical behaviour of the GDP growth rates and inflation also appears in Sub‐Saharan countries until the third interval (60–90%). However, the highest growth rate of the GDP and GDP per capita is registered when the public debt/GDP ratio is in the second interval (30–60%). For the countries of the Southern Africa Development Community, the highest average rate of economic growth (6.8%) is similar to North African countries, when the ratio public debt/GDP is below 30% of GDP, with an average inflation rate of 11%. A number of robustness analyses were performed and the great majority of them confirm the general analysis.     

An examination of the effect of international investors on accounting information quality in Russia

This paper investigates the impact of international investors on the quality of financial accounting information in Russia. I hypothesize that international stock ownership leads to enhanced quality and adoptions or intentions to adopt IFRS by Russian firms. Data was gathered through face-to-face interviews with 100 Saint-Petersburg firms randomly selected from the INFOWAVE data base. The results are consistent with the hypotheses.     

Human Development at Risk: Economic Growth with Pollution-Induced Health Shocks

Risks to human health stemming from polluted air, water, and soil are substantial, especially in the rapidly growing economies. The present paper develops a theoretical framework to study an endogenously growing economy which is subject to pollution-induced health shocks with the health status being an argument of the welfare function. Pollution, arising as a negative externality from production, adversely and randomly affects the regeneration ability of a human body leading to a decline in the overall health status of the population. We include two types of uncertainty surrounding the health status: continuous small-scale fluctuations, driven by the Wiener process, and large-scale shocks or epidemics, driven by the Poisson process. We derive closed-form analytical solutions for the optimal abatement policy and the growth rate of consumption. Devoting a constant fraction of output to emissions abatement delivers the first-best allocation. This fraction is an increasing function of total factor productivity, polluting intensity of production, and damage intensity of both continuous and jump-type shocks. A higher frequency of jumps also calls for more vigorous abatement policies. By contrast, the optimal growth rate of the economy is decreasing in the frequency and intensity of shocks and in the polluting intensity of output. The efficiency of abatement technology has, in general, an ambiguous bearing on both the growth rate and on the abatement share due to the opposing forces of the direct and indirect effects.

Trapped in Informality: The Big Role of Small Firms in Russia’s Statist-patrimonial Capitalism

Manifestations of patrimonialism such as corruption and state predation on business are widespread in many emerging economies. This paper presents the case of Russian political economy, dubbed ‘statist-patrimonial capitalism’, which is marked by state threats to private property rights through bureaucratic extortion or legal harassment. How can we explain the resilience of Russia’s statist-patrimonial capitalism? Predominant accounts focus on the lack of institutional constraints on state predation. The paper offers a different perspective by exploring the often-overlooked contribution of small- and medium-sized enterprises (SMEs). First, statistical data show a steady rise of SMEs in the 2000s despite increasing state predation, suggesting that SMEs are not simply subjugated by the state. Second, in-depth interviews with Russian entrepreneurs reveal that business contributes to the maintenance of the statist-patrimonial system through the mechanism of the ‘informality trap’: firms that choose the informal strategy have difficulties to return to the legal sphere and get stuck in informality. The drivers of informality include firm-specific characteristics, institutional factors and socio-cultural factors dubbed ‘normality’. The mechanism of the ‘informality trap’ highlights the agency of firms in corrupt polities and may be applicable to other emerging economies.     

Beyond the manual: Practicing deliberative visioning in a Greek island

Deliberative visioning refers to processes of inclusive, multi-stakeholder deliberation over a desirable future. Methodologies include scenario workshops, future searches and community visioning. This paper looks critically at the assumptions of deliberative visioning benefiting from a case study in Greece. We argue that there are fundamental choices to be made concerning how to frame the process, who to invite and how to facilitate it. These are not just a matter of following manuals' good practice guidance. We emphasize the need for epistemological and methodological awareness of: the assumptions which frame DV itself; the assumptions of the users of DV; and the situation in which DV is deployed. We find that whereas visioning motivates participants to work together and provides a good framework to systematize discussion, it is not necessarily effective for developing systemic perspectives and plan actions. This is especially true in contexts such as that of our case study, where there is lack of a collaborative culture and there are insufficient mechanisms that integrate effectively a deliberative process with other processes of policy or social change.     

Forecasting the Malmquist productivity index

The Malmquist Productivity Index (MPI) suggests a convenient way of measuring the productivity change of a given unit between two consequent time periods. Until now, only a static approach for analyzing the MPI was available in the literature. However, this hides a potentially valuable information given by the evolution of productivity over time. In this paper, we introduce a dynamic procedure for forecasting the MPI. We compare several approaches and give credit to a method based on the assumption of circularity. Because the MPI is not circular, we present a new decomposition of the MPI, in which the time-varying indices are circular. Based on that decomposition, a new working dynamic forecasting procedure is proposed and illustrated. To construct prediction intervals of the MPI, we extend the bootstrap method in order to take into account potential serial correlation in the data. We illustrate all the new techniques described above by forecasting the productivity index of 17 OECD countries, constructed from their GDP, labor and capital stock.     

Networks of queues with infinite servers in each node applied to the management of a two echelons repair system

After a report of results about infinite servers queues, essentially on its busy period, a model is built, using networks of queues with infinite servers in each node, to study a two echelons repair system for example of a fleet of aircraft, shipping or trucks. The customers are the failures, and their service time is the time that goes from the instant at which they occur till they are completely repaired. The failing repairs occur in a base or in a remote station. The whole failures detected in the base are repaired there. Some of the failures detected in the station are repaired there and the others in the base. The results referred above allow the determination of a two echelons repair system performance measures. In this application, models of Carrillo （1991） and Ferreira （1996） are considered, improved and completed. The theory is illustrated with a numerical example.     

The influence of age and gender on food choice: a focus group exploration

With 25% of the UK population predicted to be obese by 2010, the costs to individuals and society are set to rise. Due to the extra economic and social pressures obesity causes, there is an increasing need to understand what motivates and prevents consumers from eating a healthy diet so as to be able to tailor policy interventions to specific groups in society. In so doing, it is important to explore potential variations in attitudes, motivation and behaviour as a function of age and gender. Both demographic factors are easily distinguished within society and a future intervention study which targets either, or both, of these would likely be both feasible and cost‐effective for policy makers. As part of a preliminary study, six focus groups (total n = 43) were conducted at the University of Reading in November 2006, with groups segmented on the basis of age and gender. In order to gather more sensitive information, participants were also asked to fill out a short anonymous questionnaire before each focus group began, relating to healthy eating, alcohol consumption and body dissatisfaction. Making use of thematic content analysis, results suggested that most participants were aware of the type of foods that contribute to a healthy diet and the importance of achieving a healthy balance within a diet. However, they believed that healthy eating messages were often conflicting, and were uncertain about where to find information on the topic. Participants believed that the family has an important role in educating children about eating habits. Despite these similarities, there were a number of key differences among the groups in terms of their reasons for making food choices. Older participants (60+ years old) were more likely to make food choices based on health considerations. Participants between the ages of 18–30 were less concerned with this link, and instead focused on issues of food preparation and knowledge, prices and time. Younger female participants said they had more energy when they ate healthier diets; however, very often their food choices related to concern with their appearance. Older female participants also expressed this concern within the questionnaire, rather than in the group discussions. Overall, these results suggest that consumer motivations for healthy eating are diverse and that this must be considered by government, retailers and food producers.
