STRATEGIES DEVELOPED BY LEADING EU AGRI-FOOD COOPERATIVES IN THEIR GROWTH MODEL

The rationale for this paper is the problem relating to the growth of agricultural cooperatives in Spain in recent years in comparison to increasingly concentrated food distribution, which captures most of the value added. This paper analyses the evolution and status of other countries within Europe where the need for business consolidation has been successfully addressed. For this purpose, there have been identified 7 cases to be studied: Kerry group, Irish Dairy Board, Arla Foods, The Greenery BV, Danish Crown, Agrifirm and DLG. The specific results of interviews with the senior management of this cooperatives were analyzed and organized into four blocks in which the issues raised are grouped (legal and institutional framework, strategic vision, business growth models and market standing). A number of specific aims are also pursued:  Identify the main barriers and problems faced by this type of cooperatives.  Show the strategies developed by leading cooperatives in their sector within the current comparative context.  Become familiar with the different growth models these cooperatives use to achieve and maintain their market standing.Agribusiness,

Does post merger financial performance improve after agrifood mergers of cooperatives? An empirican analysis

This study was carried out to characterize the mergers and acquisitions undertaken in the Spanish agrifood sector during the period 1995-2005 and has two objectives. Firstly, it aims to determine the manner in which economic-financial factors influence the type of merger carried out (merger by formation of a new legal person and merger by acquisition), and the role played by cooperatives (acquirer, acquired or cooperative involved in a merger by formation). Secondly, it aims to determine whether these mergers have contributed to reaching any of the objectives they were set out to achieve: improving the economic-financial situation of the companies involved, increasing income and reducing relative costs. The results obtained show that on average, following a merger, there were no statistically significant improvements in the economic-financial indicators studied.Agribusiness, Agricultural Finance,

Representational organization of novel task sets during proactive encoding

Recent multivariate analyses of brain data have boosted our understanding of the organizational principles that shape neural coding. However, most of this progress has focused on perceptual visual regions (Connolly et al., 2012), whereas far less is known about the organization of more abstract, action-oriented representations. In this study, we focused on humans{\textquoteright} remarkable ability to turn novel instructions into actions. While previous research shows that instruction encoding is tightly linked to proactive activations in fronto-parietal brain regions, little is known about the structure that orchestrates such anticipatory representation. We collected fMRI data while participants (both males and females) followed novel complex verbal rules that varied across control-related variables (integrating within/across stimuli dimensions, response complexity, target category) and reward expectations. Using Representational Similarity Analysis (Kriegeskorte et al., 2008) we explored where in the brain these variables explained the organization of novel task encoding, and whether motivation modulated these representational spaces. Instruction representations in the lateral prefrontal cortex were structured by the three control-related variables, while intraparietal sulcus encoded response complexity and the fusiform gyrus and precuneus organized its activity according to the relevant stimulus category. Reward exerted a general effect, increasing the representational similarity among different instructions, which was robustly correlated with behavioral improvements. Overall, our results highlight the flexibility of proactive task encoding, governed by distinct representational organizations in specific brain regions. They also stress the variability of motivation-control interactions, which appear to be highly dependent on task attributes such as complexity or novelty.SIGNIFICANCE STATEMENTIn comparison with other primates, humans display a remarkable success in novel task contexts thanks to our ability to transform instructions into effective actions. This skill is associated with proactive task-set reconfigurations in fronto-parietal cortices. It remains yet unknown, however, how the brain encodes in anticipation the flexible, rich repertoire of novel tasks that we can achieve. Here we explored cognitive control and motivation-related variables that might orchestrate the representational space for novel instructions. Our results showed that different dimensions become relevant for task prospective encoding depending on the brain region, and that the lateral prefrontal cortex simultaneously organized task representations following different control-related variables. Motivation exerted a general modulation upon this process, diminishing rather than increasing distances among instruction representations

Advancing medicine one research note at a time: the educational value in clinical case reports

A case report—a brief written note that describes unique aspects of a clinical case—provides a significant function in medicine given its rapid, succinct, and educational contributions to scientific literature and clinical practice. Despite the growth of, and emphasis on, randomized clinical trials and evidenced-based medicine, case reports continue to provide novel and exceptional knowledge in medical education. The journal BMC Research Notes introduces a new “case reports” section to provide the busy clinician with a forum in which to document any authentic clinical case that provide educational value to current clinical practice. The aim is for this article type to be reviewed, wherever possible, by specialized Associate Editors for the journal, in order to provide rapid but thorough decision making. New ideas often garnered by and documented in case reports will support the advancement of medical science — one research note at a time

Weak ergodicity breaking of receptor motion in living cells stemming from random diffusivity

Molecular transport in living systems regulates numerous processes underlying biological function. Although many cellular components exhibit anomalous diffusion, only recently has the subdiffusive motion been associated with nonergodic behavior. These findings have stimulated new questions for their implications in statistical mechanics and cell biology. Is nonergodicity a common strategy shared by living systems? Which physical mechanisms generate it? What are its implications for biological function? Here, we use single particle tracking to demonstrate that the motion of DC-SIGN, a receptor with unique pathogen recognition capabilities, reveals nonergodic subdiffusion on living cell membranes. In contrast to previous studies, this behavior is incompatible with transient immobilization and therefore it can not be interpreted according to continuous time random walk theory. We show that the receptor undergoes changes of diffusivity, consistent with the current view of the cell membrane as a highly dynamic and diverse environment. Simulations based on a model of ordinary random walk in complex media quantitatively reproduce all our observations, pointing toward diffusion heterogeneity as the cause of DC-SIGN behavior. By studying different receptor mutants, we further correlate receptor motion to its molecular structure, thus establishing a strong link between nonergodicity and biological function. These results underscore the role of disorder in cell membranes and its connection with function regulation. Due to its generality, our approach offers a framework to interpret anomalous transport in other complex media where dynamic heterogeneity might play a major role, such as those found, e.g., in soft condensed matter, geology and ecology.Comment: 27 pages, 5 figure
