How is a global sensitivity analysis of a catchment-scale, distributed pesticide transfer model performed? Application to the PESHMELBA model

Pesticide transfers in agricultural catchments are responsible for diffuse but major risks to water quality. Spatialized pesticide transfer models are useful tools to assess the impact of the structure of the landscape on water quality. Before considering using these tools in operational contexts, quantifying their uncertainties is a preliminary necessary step. In this study, we explored how global sensitivity analysis could be applied to the recent PESHMELBA pesticide transfer model to quantify uncertainties on transfer simulations. We set up a virtual catchment based on a real one, and we compared different approaches for sensitivity analysis that could handle the specificities of the model: a high number of input parameters and a limited size of sample due to computational cost and spatialized output. After a preliminary screening step, we calculated Sobol' indices obtained from polynomial chaos expansion, Hilbert–Schmidt independence criterion (HSIC) dependence measures and feature importance measures obtained from random forest surrogate model. Results from the different methods were compared regarding both the information they provide and their computational cost. Sensitivity indices were first computed for each landscape element (site sensitivity indices). Second, we proposed to aggregate them at the hillslope and the catchment scale in order to get a summary of the model sensitivity and a valuable insight into the model hydrodynamic behaviour. Conclusions about the advantages and disadvantages of each method may help modellers to conduct global sensitivity analysis on other such modular and distributed hydrological models as there has been a growing interest in these approaches in recent years.</p

A new research agenda for managing socio-cultural integration

Post-acquisition socio-cultural integration has received increasing attention from both scholars and practitioners since the early 1990s. During the past decade, research has increasingly focused on emotions and identity in mergers and acquisitions. This chapter introduces the reader to the vibrant research field and its relevance. This section sets the scene for the book, which provides a deeper understanding of how emotions—both positive and negative—as well as values and identity enable a deeper socio-cultural integration after a merger or acquisition, and how leadership plays a crucial role in making it all happen. This chapter also highlights how the Nordic approach to post-acquisition socio-cultural integration refers to a large community of Nordic academics focusing on the softer social and human side of acquisition, often relying on a huge variety of qualitative methods, and to Nordic companies that are not afraid of adopting a more collaborative approach to post-acquisition integration

Family Business Restructuring:A Review and Research Agenda

Although business restructuring occurs frequently and it is important for the prosperity of family firms across generations, research on family firms has largely evolved separately from research on business restructuring. This is a missed opportunity, since the two domains are complementary, and understanding the context, process, content, and outcome dimensions is relevant to both research streams. We address this by examining the intersection between research on business restructuring and family firms to improve our knowledge of each area and inform future research. To achieve this goal, we review and organize research across different dimensions to create an integrative framework. Building on current research, we focus on 88 studies at the intersection of family firm and business restructuring research to develop a model that identifies research needs and suggests directions for future research

Sales and Marketing Integration : A Proposed Framework

International audienceIn this paper, we identify sales and marketing activities, and common impediments to their integration. We then discuss the concept of sales-marketing integration, and distinguish it from related concepts such as involvement and communication. Following this, we discuss approaches businesses can use to improve sales-marketing integration as well as their potential costs and drawbacks. The paper concludes with a set of propositions identifying the conditions under which sales-marketing integration has the greatest impact on firm performanc
