Scoping river basin management issues with participatory modelling: The Baixo Guadiana experience

This paper details the design and implementation of a participatory modelling process in the Baixo Guadiana River Basin, in Portugal. A group of stakeholders was involved in a causal mapping exercise that lead to the development of a shared view of the problems, pressures and impacts characterizing the river basin. A simulation model was also developed to support experimentation with alternative management scenarios for the area. The paper looks critically at the evaluation of the participatory modelling outcomes, both at the individual and group levels, discussing the role of this approach in supporting the scoping stages of river basin planning and management processes. On the downside, the unstable group composition seems to have hindered the chances of producing a higher impact in the functioning of the group, and subsequently the capacity to sustain the level of collaboration required to achieve the strategic river basin objectives established during the participatory modelling process. The paper discusses the issue of group stability as well as some options to overcome the limitations of unstable participant groups. The strengths of participatory modelling, as underlined by the Baixo Guadiana experience, include the flexibility to adapt the method to different contexts and participatory designs and the capacity to structure the active involvement of stakeholders, providing an open and shared language for collaborative policy design, fostering learning and knowledge integration.     

Developing cross-cultural competencies through international corporate volunteerism

We propose three features of cross-cultural experiences, contextual novelty, project meaningfulness and social support, facilitate the development of cross-cultural competencies. Using a longitudinal design, the employees in Study 1 participated in an international corporate volunteerism program designed with all three features. These results found a positive change over time in cross-cultural competencies. Results of Study 2, also longitudinal, suggest that the participants’ post-assignment cross-cultural competencies are the highest: (1) when employees with higher baseline cross-cultural competencies work in high contextual novelty (i.e., international location) and (2) when employees with lower baseline cross-cultural competencies work in low contextual novelty (i.e., domestic location).     

Impact of innovation policies on small,medium and large Brazilian firms

This study comprises a comparative examination of the effects of innovation support programmes’ spend on innovative activities in small, medium and large Brazilian firms. The econometric methodology propensity score matching is used to assess the impacts of tax and financial incentives based on. Results show that innovation support programmes stimulate expenditure on innovative activities, especially financial incentives for the acquisition of machinery and equipment.     

The Export Performance of the 2004 EU Enlargement Economies since the 1990s: a Constant Market Share Analysis

This study focuses on the export performance of the 2004 European Union (EU) enlargement economies to the EU15 between 1990 and 2013. The long time span analysed allows to capture different stages in the relationship of these new members with the EU before and after accession. The study is based on the constant market share methodology of decomposing an ex-post country’s export performance into different effects. Two constant market share analyses were selected in order to disentangle (i) the growth rate of exports and (ii) the growth rate of exports relatively to the world. Both approaches are applied to manufactured products grouping products in different classifications of sectors. Results provide information on export performance for the ten economies individually considered, including the importance of each EU15 destination market.     

When transparency pays off: Enticing sceptical consumers with two-sided advertising

It has been generally assumed that higher levels of scepticism towards advertising invariably lead to higher resistance to advertising appeals. The main purpose of the present research was to examine whether highly sceptical consumers' resistance can be overcome by appeals associated with higher credibility. We tested our hypotheses using message sidedness as an advertising variable that has been associated with higher (two-sided) versus lower (one-sided) credibility. In three experimental studies, we examined more versus less sceptical consumers' responses to two- versus one-sided appeals. We found that two-sided messages are more effective in increasing purchase intentions, through enhanced credibility, but only for consumers who are more sceptical of advertising. Less sceptical consumers trust both messages equally and their purchase intentions are not affected by the type of message. Importantly, we also showed that highly sceptical consumers trust two-sided appeals as much as their less sceptical counterparts. The study contributes to the literature on advertising and persuasion knowledge by showing that advertising scepticism does not elicit a single response tendency, as originally conceptualized. Rather, advertising scepticism is more consistent with the underpinnings of the Persuasion Knowledge Model, in that higher knowledge about persuasion tactics aids consumers to better cope with, and not invariably resist persuasion attempts. We conclude that transparency pays off because it may entice a more sceptical audience and, at the same time, it does not harm less sceptical consumers' trust and purchase intentions.     

Reliability performance of fault-tolerant digital control systems

This paper presents the results of a generic reliability analysis of fault-tolerant digital control systems (F-T DCS). This analysis differs from previous efforts at estimating the reliability performance of F-T DCS in the sense that this analysis relies extensively on actual experience with redundant computer systems rather than on theoretical evaluations. The dominant contributors to the frequency of failure of F-T DCS are (1) failures within common or shared equipment, (2) software failures, and (3) inadvertent operator actions. Other contributors include loss of electric power, spurious signals that originate from within the DCS, lack of coverage, common cause failure (CCF) of redundant hardware, CCF of instrument channels, and physical damage from externally initiated events (e.g., high temperature). Much variation is expected in the reliability performance of F-T DCSs. Although some systems may operate for 10 or 15 years without experiencing system failures, other systems may fail several times during the same time interval. This variation is expected among systems of different architectures as well as among systems of the same architecture. Because most failures of DCSs can be traced to some kind of CCF, particularly software failures and inadvertent operator actions, CCFs should probably receive more attention than they are presently given when selecting an F-T DCS.     

The Voluntary Continuation in the Obligatory System of the Social Security Law

The system of obligatory insurance, regulated by the Social Security Law, includes the design of a mixed system, which allows workers to continue contributing to the social security. This mixed system, called voluntary continuation in the obligatory system, contemplates the option for workers who have concluded a work relationship and who wish to continue accumulating weekly contributions necessary to obtain the disability and life insurance rights, such as those of dismissal in old age, and are considered in the Social Security Act of 1973.     

The Wicked Character of Sustainable Supply Chain Management: Evidence from Sustainability Reports

Supply chains are changing their business paradigm as they strive for sustainability and not just for increasing profits. Sustainability, however, is a concept that is open to interpretation since it is based on societal and organizational values. Little is known about what companies actually mean when referring to sustainability, and how this contrasts with the understanding at different echelons of the supply chain. Diverging interpretations and translations of sustainability among stakeholders, termed wicked problems, affect the progress of sustainable supply chain management. This paper aims to contribute to closing the gap between our common sense expectations and the actual evidence from sustainability reports of how sustainability evolves from abstract ideas to operational practices across the supply chain. To this end, this study employs a computer‐aided content analysis of 142 corporate sustainability reports across 12 industries. Building on the findings, and using the lens of wicked problems, this paper provides guidance to practitioners on how to develop strategies that are effective across the whole supply chain.

CEO duality and organizational performance: A longitudinal analysis

All public corporations must make a choice regarding board leadership structure. Advocates of more effective corporate governance argue for independent board leadership; yet many firms choose instead to allow the CEO to serve as board chairperson (CEO duality). This study examines the differential financial implications of these choices for 141 corporations over a 6-year time period. Results indicate significant differences in performance between the two groups along a number of performance measures; more specifically, firms opting for independent leadership consistently outperformed those relying upon CEO duality.     

Getting along long distance: understanding conflict in a multinational team through network analysis

Multinational companies (MNCs) create international teams to pool global talent and meet organizational goals. But the many differences among team members are fertile ground for conflict. While traditional conflict management techniques gather all team members together to resolve or minimize conflicts, geographic dispersion greatly increases the time, money, and disruption to daily workflow activities necessary to bring multinational teams together. We use a social network perspective to identify and prioritize conflicts to increase team effectiveness, allowing management to focus on the most critical conflicts first. Further, we show that the most critical conflict might not be between headquarters and country subsidiaries, but between two country subsidiaries.
