    The aim of this paper is to explore the governance effectiveness of St Anne Marine National Park, Seychelles. By collecting qualitative data through interviews and ethnographic observations from different constituencies in May and June 2018, the Marine Protected Area Governance (MPAG) analysis framework was applied. This case study revealed that the site is governed by a parastatal organisation (SNPA) and its Board through a largely ineffective top-down, government-led approach. The primary threats to the success of the park that fall within the purview of MPA (marine protected area) governance, are poaching, coastal development and unsustainable tourism, with a clear lack of state capacity, political will and capacity for enforcement as the key drivers undermining equitable and effective governance. Additionally, the study revealed a lack of community involvement in decision-making processes, resulting in a lack of sufficient participation and knowledge incentives, which reflects the need for the inclusion of more bottom-up governance approaches. This study contributes to the broader conceptual framework by supporting the understanding that a combination of governance approaches are needed to achieve MPA objectives and resilience. The governance structure coupled with the identified conflicts and many additional driving forces and constraints discussed throughout, are obstructing the achievement of strategic MPA objectives and severely undermining effectiveness. Suggestions for improvement are therefore explored as significant governance modifications are clearly needed. Since the completion of this research, significant advances have been made to the governance of SAMNP and where relevant these have been noted briefly throughout the paper

    Omega-3 Fatty Acids Modify Human Cortical Visual Processing—A Double-Blind, Crossover Study

    While cardiovascular and mood benefits of dietary omega-3 fatty acids such as docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are manifest, direct neurophysiological evidence of their effects on cortical activity is still limited. Hence we chose to examine the effects of two proprietary fish oil products with different EPA∶DHA ratios (EPA-rich, high EPA∶DHA; DHA-rich) on mental processing speed and visual evoked brain activity. We proposed that nonlinear multifocal visual evoked potentials (mfVEP) would be sensitive to any alteration of the neural function induced by omega-3 fatty acid supplementation, because the higher order kernel responses directly measure the degree of recovery of the neural system as a function of time following stimulation. Twenty-two healthy participants aged 18–34, with no known neurological or psychiatric disorder and not currently taking any nutritional supplementation, were recruited. A double-blind, crossover design was utilized, including a 30-day washout period, between two 30-day supplementation periods of the EPA-rich and DHA-rich diets (with order of diet randomized). Psychophysical choice reaction times and multi-focal nonlinear visual evoked potential (VEP) testing were performed at baseline (No Diet), and after each supplementation period. Following the EPA-rich supplementation, for stimulation at high luminance contrast, a significant reduction in the amplitude of the first slice of the second order VEP kernel response, previously related to activation in the magnocellular pathway, was observed. The correlations between the amplitude changes of short latency second and first order components were significantly different for the two supplementations. Significantly faster choice reaction times were observed psychophysically (compared with baseline performance) under the EPA-rich (but not DHA-rich) supplementation, while simple reaction times were not affected. The reduced nonlinearities observed under the EPA-rich diet suggest a mechanism involving more efficient neural recovery of magnocellular-like visual responses following cortical activation

    Epilepsy and Psychiatric Comorbidities: Drug Selection.

    Purpose of review The pharmacological treatment of patients with epilepsy and psychiatric comorbidities may sometimes represent a therapeutic challenge. This review is focused on the pharmacological management of patients with epilepsy and psychiatric problems in terms of rationalization of the antiepileptic drug (AED) treatment and the pharmacological management of the most clinically relevant psychiatric comorbidities, namely mood and anxiety disorders, psychoses, and attention deficit hyperactivity disorder (ADHD). Recent findings Up to 8% of patients with drug-resistant epilepsy develop treatment-emergent psychiatric adverse events of AED regardless of the mechanism of action of the drug and this is usually related to an underlying predisposition given by the previous psychiatric history and the involvement of mesolimbic structures. Careful history taking, periodic screening for mood and anxiety disorders, low starting doses, and slow titration schedules can reduce the possibility of AED-related problems. A pragmatic checklist for the pharmacological management of patients with epilepsy and psychiatric disorders is presented. Summary patients should be informed of potential behavioral effects of AEDs but no drugs should be excluded a priori. Any psychiatric comorbidity should be addressed in the appropriate setting and full remission and recovery should always represent the first goal of any therapeutic intervention. Neurologists should be aware of the side effects of major psychotropic drug classes in order to fully counsel their patients and other health professionals involved
