Around 10 - 14% of the general population (USA & Northern Europe) suffer from a noticeable degree of hearing loss and would benefit from some form of hearing assistance or deaf aid. Disability legislation and requirements in many countries mean that many more hearing assistive systems are being installed - yet there is continuing evidence to suggest that many of these systems fail to perform adequately and provide the benefit expected. In particular Assistive Listening Systems (ALS) provided in many theatres, concert halls and similar auditoria are often not primarily designed with the hearing impaired in mind but rather are an adjunct to a show relay, back of house communications system. Even where Assistive Listening is the primary function many systems still fail to deliver an appropriate signal or adequate intelligibility. The paper reviews current practice and puts forward a number of guideline proposals that will hopefully help improve the situation. In particular, speech intelligibility requirements are addressed. ©(2012) by the Audio Engineering Society.

Purpose: The purpose of this paper is to explore differences in wine preferences between Generation Y and older cohorts in the USA. Design/methodology/approach: A total of 260 US consumers participated in a web-based survey that took place in April 2010. The best-worst scaling method was applied measuring the level of importance given by participants to a list of most common attributes used in choice of wine. Independent sample t-tests were applied to compare the best-worst scores between Generation Y and older cohorts. Findings: Differences were found in the level of importance that Generation Y gives to wine attributes in comparison to older cohorts. Generation Y was found to attach more importance to attributes such as "Someone recommended it", "Attractive front label" and "Promotional display in-store", whereas older cohorts gave more importance to attributes such as "I read about it" and "Grape variety". This suggests that Generation Y preferences for wine are driven by marketing added-value activities such as promotions and labelling, whereas limited importance is given to information about wine, reflecting lack of subjective knowledge, experience and involvement about wine. Research limitations/implications: This research adds to generation-based research in wine marketing and contributes towards a better understanding of the differences between generation cohorts in relation to their preferences towards wines. Originality/value: This study is among the first to compare wine preferences of Generation Y with older cohorts using the best-worst scaling method. © Emerald Group Publishing Limited.

Crab larval dispersal and, thus, adult population size can be influenced by oceanographic conditions, especially in highly dynamic and variable environments such as high-latitude estuaries. This study's primary goal was to understand larval timing, abundance, and distribution in relation to oceanographic effects between the more estuarine inner and more oceanic outer part of the subarctic estuary of Kachemak Bay (south-central Alaska, USA). Temperature and salinity measurements and plankton tows were taken along the boundary between the two bay parts from 31 March to 28 October 2008 on spring and neap tides. Summer water flow and stratification in Kachemak Bay were chiefly buoyancy driven, and predominant flow patterns were not affected by the large tidal range in the region. Larvae of seven brachyuran species were found over the sampling period, with seasonally different peak abundances. Larval spatial distribution patterns, presence of most larval stages for each species, and their seasonal timing and persistence within the water column suggest that most species are locally transported within or close to Kachemak Bay. The larval assemblage was correlated with seasonal changes in water temperature, and peak abundances of some species coincided with spring tides and/or frontal systems between the in- and outflow regions of the bay. The strong influence of freshwater on the local circulation pattern in the summer indicates that larval transport will likely be strongly affected by future changes in glacial melt and precipitation. © 2013 Coastal and Estuarine Research Federation.
