Italian guidelines for primary headaches: 2012 revised version

The first edition of the Italian diagnostic and therapeutic guidelines for primary headaches in adults was published in J Headache Pain 2(Suppl. 1):105–190 (2001). Ten years later, the guideline committee of the Italian Society for the Study of Headaches (SISC) decided it was time to update therapeutic guidelines. A literature search was carried out on Medline database, and all articles on primary headache treatments in English, German, French and Italian published from February 2001 to December 2011 were taken into account. Only randomized controlled trials (RCT) and meta-analyses were analysed for each drug. If RCT were lacking, open studies and case series were also examined. According to the previous edition, four levels of recommendation were defined on the basis of levels of evidence, scientific strength of evidence and clinical effectiveness. Recommendations for symptomatic and prophylactic treatment of migraine and cluster headache were therefore revised with respect to previous 2001 guidelines and a section was dedicated to non-pharmacological treatment. This article reports a summary of the revised version published in extenso in an Italian version

Behaviours Associated with Acoustic Communication in Nile Tilapia (Oreochromis niloticus)

Sound production is widespread among fishes and accompanies many social interactions. The literature reports twenty-nine cichlid species known to produce sounds during aggressive and courtship displays, but the precise range in behavioural contexts is unclear. This study aims to describe the various Oreochromis niloticus behaviours that are associated with sound production in order to delimit the role of sound during different activities, including agonistic behaviours, pit activities, and reproduction and parental care by males and females of the species.Sounds mostly occur during the day. The sounds recorded during this study accompany previously known behaviours, and no particular behaviour is systematically associated with sound production. Males and females make sounds during territorial defence but not during courtship and mating. Sounds support visual behaviours but are not used alone. During agonistic interactions, a calling Oreochromis niloticus does not bite after producing sounds, and more sounds are produced in defence of territory than for dominating individuals. Females produce sounds to defend eggs but not larvae.Sounds are produced to reinforce visual behaviours. Moreover, comparisons with O. mossambicus indicate two sister species can differ in their use of sound, their acoustic characteristics, and the function of sound production. These findings support the role of sounds in differentiating species and promoting speciation. They also make clear that the association of sounds with specific life-cycle roles cannot be generalized to the entire taxa

Total economic value, ecosystem services and the role of public policy instruments in the creation and destruction of forest values

Established frameworks such as the Millennium Ecosystem Assessment (MEA) and the Total Economic Value (TEV) recognize how forest ecosystems have extrinsic and intrinsic value to society. We critically discuss the appropriateness of attempting to adapt a service-dominant logic (S-D logic) framework to meet the unique characteristics of forest ecosystems by incorporating elements from the MEA and TEV. This chapter enriches the current discussion related to S-D logic and forests by including inherent values in-neglect, no-use and no-trade. These categories highlight how the value of forests can be created or destroyed when forest owners neglect values to their wellbeing or when absence of transactions fail to clearly define beneficiaries. Within an overview of Services in Family Forestry we argue and illustrate how the process of participation in public policy programs can influence individual and collective value co-creation and co-destruction. Moreover, institutions can play a critical role in the value creation process as brokers between beneficiaries
