Trust and community building in the Doñana (Spain) toxic spill disaster

Appeals to public participation and, more generally, to a wider involvement of civic networks in the management of environmental conflicts are becoming more common after the difficulties that both the Market and the State appear to have in regulating these conflicts. The concern of this paper is with how central elements in civic society, such as interpersonal trust and community-building mechanisms, are influenced by environmental catastrophes. The case of the toxic spill disaster in Doñana, Spain, is presented in order to examine whether this accident had any effect on interpersonal trust and the mobilization of civic networks in the area. From the analysis, it can be concluded that involvement of civic networks in the management of these situations depends on the magnitude (real or perceived) of the disaster but also on the performance of public institutions regarding the event.     

Sustainability reporting and stakeholder engagement in Spain: Different instruments,different quality

The purpose of this paper is to compare the quality of the sustainability information issued following the three most common reporting models: annual report (addressed to shareholders), sustainability report (addressed to stakeholders), and integrated report (addressed to shareholders). To this aim, we create a quality index based on previous literature, analyzing the content of the sustainability information disclosed by Spanish listed companies during the years 2013 to 2015. We find that companies issuing sustainability reports or integrated reports provide higher quality information than companies including their sustainability information within the annual report. We also find that sustainability reports are issued with higher quality than integrated reports. Both findings indicate that companies in Spain are engaged in a dialogue with all stakeholders, not only shareholders. Our results offer insights on the need to improve the framework of the integrated report in order to achieve the objectives of the International Integrated Reporting Council and to get a speed up in the adoption of this new reporting tool.     

Exploring the Relationship between Sustainability Reporting and Sustainability Management Practices

There has been a dramatic uptake of sustainability reporting (SR) and sustainability management practices over the last two decades, in turn raising questions about the relationship between external disclosure and internal practice of corporate sustainability. Previous literature has emphasized the role of external pressures in driving SR adoption. However, as recent practitioner surveys also identify the existence of internal motives for SR, a more comprehensive analysis of this relationship is needed. In order to address this issue, we develop a framework accounting for four company‐level SR configurations, resulting from different levels of importance of external and internal motives for SR. Then, four exploratory cases serve to illustrate these configurations and to describe the respective roles of SR at the company level. As considerable diversity among these SR practices is found, our findings point to the relevance of both external and internal motives in understanding SR contribution to corporate sustainability.

Bottom-up framework for cost allocation to services in telecommunication networks

Communications service providers (CSP) supply information, transport and passive infrastructure services that rely on the deployment of multiservice networks. To attain service cost reductions, the planning and design of those networks is essential, so that the total cost of the network ownership (TCO) is minimized. In this paper, we propose a bottom-up calculation framework for the allocation of the TCO cost components (i.e. capital and operational expenditures) to the services supplied by a CSP. For this, the framework is formulated within the context of the network life-cycle. Our method provides the level of abstraction required for the calculation of the three basic service cost contributors, namely, direct, shared and common costs. Moreover, it outlines the role of network planning in the design of an efficient network infrastucture, and in the calculation of the TCO. Based on this, we show how the stand alone, fully allocated and long-run incremental costs of a service can be calculated. Besides the determination of service cost drivers, the framework is useful to evaluate the cost-efficiency of competing technologies. To illustrate this, we study the allocation of the infrastructure costs for a CSP offering transport services with an optical network. By designing the infrastructure with fixed-grid and flex-grid technologies, it is shown that in both cases the main service cost driver is determined by the transponders installed. The results show that fixed-grid fits well for the provisioning of high speed constant bit-rate transport services, whereas flex-grid is a good candidate for transport services with bursty traffic patterns.     

GOAL PROGRAMMING AND MULTIPLE CRITERIA DECISION-MAKING IN FARM PLANNING: SOME EXTENSIONS

This paper is the sequel to a previous article by Romero and Rehman on the role of multiple criteria decision-making (MCDM) techniques, particularly goal programming (GP), in farm planning. This assessment of the potential usefulness of the MCDM paradigm is carried further and now covers the extensions to GP and other related methodologies such as multiobjective programming, compromise programming, multigoal programming and generalised GP. Later analysis is focused on methods of dealing with uncertainty and risk in farm planning models, by demonstrating how game theoretic principles and the MOTAD approach (along with its main variant, target MOTAD) can be incorporated within the MCDM framework.     

Dynamics of smallholder participation in horticultural export chains: evidence from Ecuador

We study the dynamics of smallholder participation in export value chains focusing on the example of small‐scale broccoli producers in the highlands of Ecuador. Combining cross‐sectional data from a household survey with 11‐year longitudinal data on export market transactions, we explain the hazards of dropping out of a high‐value export chain. We apply a multispell cox duration model that allows us to consider multiple entries and exits from the supply chain. We also provide evidence on the welfare impacts associated with participation. The results suggest that small‐scale farmers’ exit from the export sector is accelerated by high transaction risks experienced in the past. While we find no particular evidence for the exclusion of small‐scale farmers from the export sector, we do find that poorer households and female‐headed households tend to drop out faster, especially as long as the sector is still prospering. Finally, when considering welfare effects, we do not find evidence that participation translates into tangible benefits for broccoli farmers. We discuss some measures that could help improve the long‐term sustainability of smallholder integration in high‐value chains.     

Interviewing and surveying over the phone: a reflexive account of a research on parenting

This paper is on the role that the phone plays in a mixed-methods empirical research. In the current sociological literature, the phone is a methodological object associated with quantitative fieldwork, while little is said on the phone as a tool for qualitative research. We reflect here on a case study on the use of parental leaves by fathers in Spain, which included the phone as the only communication tool between researchers and subjects. We collect out own experience as interviewers in the qualitative phase of the research project, and interviewed surveyors working in the field. We analyze the discursive data following grounded theory principles and compare the use of both techniques in the data gathering process, including sampling and design. Thus, we consider interviewing and surveying as mediated communication situations. Our findings show that the value of the phone as a tool for research is a matter of adequacy to a given methodology, rather than an issue of validity, reliability, or credibility.     

Multinational Corporations,Property Rights,and Legitimization Strategies: US Investors in the Argentine and Peruvian Oil Industries in the Twentieth Century

Multinational corporations in the extractive sector have historically faced challenges to their property rights, particularly in oil. International business scholars argue that firms can decrease these challenges by approaching domestic legitimating actors or seeking home government support. Through a study of the operations of Standard Oil of New Jersey in Peru and Argentina in the twentieth century, we find that these legitimating strategies can backfire due to two main elements: first, the multinational might approach actors with a different agenda from those defining, delineating, and enforcing property rights. Second, host countries can use home government support to multinationals to delegitimise foreign firms' operations.     

COMPROMISE-RISK PROGRAMMING FOR AGRICULTURAL RESOURCE ALLOCATION PROBLEMS: AN ILLUSTRATION

This paper presents a novel approach for dealing with risk in agricultural resource allocation decisions by synthesising the conventional Markowitzean, or MOTAD, methods within a compromise programming model to generate ‘best-compromise’ solutions which come closest to an ideal point defined in terms of risk minimisation. This approach can be regarded as the compromise-risk programming model. The purpose here is to show how this ‘hybridisation’ of Markowitz/MOTAD and compromise programming approaches overcomes some of the weaknesses of the traditional approach to handling risk in resource allocation models.
