AFN-1252, a FabI Inhibitor, Demonstrates a Staphylococcus-Specific Spectrum of Activity

open access: yesAntimicrobial Agents and Chemotherapy, 2009
AFN-1252, a potent inhibitor of enoyl-acyl carrier protein reductase (FabI), inhibited all clinical isolates of Staphylococcus aureus (n 502) and Staphylococcus epidermidis (n 51) tested, including methicillin (meti-cillin)-resistant isolates, at ...

How to avoid the tragedy of alternative food networks (AFNs)? The impact of social capital and transparency on AFN performance

British Food Journal, 2020
PurposeAlternative food networks (AFNs) have recently emerged in the food landscape as new ways of food production, distribution and consumption which are alternatives to the traditional food system. Drawing on the tragedy of the commons, this paper aims to test the role played by social capital and transparency in reducing customer's lethargy and thus

Determinants of Farmers’ Participation in AFNs

2018
In this chapter Corsi, Novelli, and Pettenati analyse the reasons that lead farmers to adopt direct selling or more generally AFNs, distinguishing between on-farm and off-farm direct sales. The issue is discussed first from a theoretical perspective. Next, empirical evidence is presented, using both quantitative and qualitative approaches. Using census

Quality and Price Setting by Producers in AFNs

2018
This chapter deals with the problem of setting prices and quality conventions among small-scale agro-food producers. Barbera, Dagnes, and Di Monaco first show how producers decide sales prices for their products and, more precisely, how relational mechanisms (e.g., imitation) mix with the moral economy (e.g., legitimate price thresholds) and economic ...

ZD, ZG and IOL Controllers for AFN System

2020
In this chapter, by following the ZG method, a ZD controller and a ZG controller are presented for the tracking control of AFN system, which may encounter the DBZ problem. For comparison, the conventional IOL controller is also presented. The ZD, ZG and IOL controllers are compared in different relative-degree cases, i.e., the standard relative-degree ...

Determinants of Participation in AFNs and Its Value for Consumers

2018
In this chapter Corsi and Novelli discuss consumers’ motivations for participating in AFNs. Some consumers are self-interested and look for healthier food, lower prices, better quality, and food freshness and taste. Others have social, political, and environmental concerns. Lastly, personal relationships can count in the decision to join AFNs.

Introduction to Part IV: Environment, Territory, and AFNs

2018
This chapter deals with AFNs’ relationship with the territory and the environment. Two sub-chapters address the environmental implications of AFNs and their territorial implications. The first sub-chapter examines the claims of AFNs’ superiority over conventional chains and presents empirical tests of the different chains’ environmental impact.

GD-Aided IOL Tracking Control of AFN System

2020
IOL may encounter the knotty DBZ problem when applied to the tracking control of affine-form nonlinear (AFN) system, which may not have a well-defined relative degree. In this chapter, we incorporate the GD into IOL, which leads to the GD-aided IOL method for conquering the DBZ problem encountered in the AFN system, with the proposition of the loose ...

Introduction to Part III: AFNs from the Producers’ Viewpoint

2018
After illustrating the long-term trends that led to the birth of AFNs, this chapter discusses producers’ participation in AFNs, their motivations and behaviour. The most obvious motivation for producers’ participation in AFNs is arguably income, but subjective preferences and social and environmental motivations can play a role.
