The Municipality of Anchorage (MOA) is required to better manage, operate and control municipal solid waste (MSW) after the Anchorage Assembly instituted a Zero Waste Policy. Two household curbside recycling programs (CRPs), pay-as-you-throw (PAYT) and single-stream, were compared and evaluated to determine an optimal municipal solid waste diversion method for households within the MOA. The analyses find: (1) a CRP must be designed from comprehensive analysis, models and data correlation that combine demographic and psychographic variables; and (2) CRPs can be easily adjusted towards community-specific goals using technology, such as Geographic Information System (GIS) and Radio Frequency Identification (RFID). Combining resources of policy-makers, businesses, and other viable actors are necessary components to produce a sustainable, economically viable curbside recycling program.

Purpose: To examine a single-optic accommodating intraocular lens (IOL) visual performance by correlating IOL implanted eyes’ defocus curve with the intraocular aberrometric profile and the impact on the quality of life (QOL). Methods: Prospective consecutive case series study including a total of 25 eyes of 14 patients with ages ranging between 52 and 79 years old. All cases underwent cataract surgery with implantation of the single-optic accommodating IOL Crystalens HD (Bausch & Lomb). Distance and near visual acuity outcomes, intraocular aberrations, the defocus curve and QOL (NEI VFQ-25) were evaluated 3 months after surgery. Results: A significant improvement in distance visual acuity was found postoperatively (p = 0.02). Mean postoperative LogMAR uncorrected near visual acuity was 0.44 ± 0.23 (20/30). 60% of eyes had a postoperative addition between 0 and 1.5 diopters (D). The defocus curve showed an area of maximum visual acuity for the levels of defocus corresponding to distance and intermediate vision (−1 to +0.5 D). Postoperative intermediate visual acuity correlated significantly some QOL indices (r ≥ 0.51, p ≤ 0.03; difficulty in going down steps or seeing how people react to things that patient says) as well as with J0 component of manifest cylinder. Postoperative distance-corrected near visual acuity correlated significantly with age (r = 0.65, p < 0.01). Conclusions: This accommodating IOL seems to be able to restore the distance visual function as well as to provide an improvement in intermediate and near vision with a significant impact on patient's QOL, although limited by age and astigmatism. Future studies with larger sample sizes should confirm all these trends.

A clear majority of Poles voted to end eight years of Civic Platform (PO) government on October 25th when they brought the national-conservative Law and Justice Party (PiS) back to power. This outcome might be difficult to understand for Poland’s West European partners and may also confuse some EU officials who have observed developments in Poland since it joined the EU in 2004. The implications of these elections for relations with Germany and France, and for Poland’s own EU policy, are a source of concern. Do the results herald a return to the country Poland was during its early years as EU member? In this EPIN commentary the author attempts to throw light on the reasons behind the return to power of Law and Justice Party and considers the wider implications for the EU and European cohesion.

Sporocarps of macrofungi have been recorded in two neighbouring pure stands of Norway spruce (Picea abies) of different age due to a wind-throw in the subalpine zone of the Alps. The still open young stand of 30 years with trees up to 6 m displayed 80 species, the mature closed forest stand 90 species. Species richness of mycorrhizal fungi is higher in the mature stand than in the younger one, however, with an almost doubled sporocarp production in the latter one. The opposite is found with saprotrophic fungi. Several fungi appeared only in one forest type confirming the concept of early stage versus late stage fungi. Wind-throws as irregular events in subalpine forests, create gaps and add considerably to the species diversity of macrofungi.
