Can imageability help us draw the line between storage and composition?

Language requires both storage and composition. However, exactly what is retrieved from memory and what is assembled remains controversial, especially for inflected words. Here, “imageability effects” is introduced as a new diagnostic of storage and a complement to frequency effects. In 2 studies of past-tense morphology, more reliable imageability and frequency effects were found on irregulars than on regulars. An interaction with sex was also observed: Males but not females showed more reliable frequency and imageability effects for irregulars than for regulars; females but not males showed signs of storage for regulars, particularly among higher frequency forms. Overall, the findings validate imageability effects as another diagnostic of storage and suggest that the line between storage and computation is not a simple function; rather, it depends upon the interplay of both item- and subject-specific factors.

Coal-Bed Methane Provides Less-Invasive Production Method

If the twenty-first century has done anything, it's allowed the extrapolation of “personalization” on a global scale. Once limited to purchasing items during set business hours from a local store's inventory, consumers now acquire everything from tailored clothing to kits of gourmet food every minute of the day—sometimes delivered to their doorsteps within hours. This revolution has redefined what it means to “provide” and “consume.”     

Defecting From the Gutenberg Legacy: Employing Images to Test Knowledge Gaps

Education‐based knowledge gaps are well‐documented across countries, media platforms, and content. Without exception, knowledge is measured through words not images. Given the centrality of sight in the natural history of Homo sapiens, the extraordinary visual acuity of humans, and the proliferation of screen‐based visual media environments in contemporary life, an experiment was conducted to test the knowledge gap visually. Participants watched 8 audiovisual news stories. Simple recognition of story details and comprehension of that information were tested in verbal and visual modalities. Results offered the first confirmation of the knowledge gap in visual terms. Yet, gaps were significantly smaller employing visual than verbal measures, pointing to the need for continued efforts to develop visual measures for future memory studies.     

Landscapes of Challenge and Change: Contested Views of the Cairngorms National Park

The Scottish model of national parks reflects wider changes in the management of special or protected landscapes. This paper uses Ingold's dwelling conceptualisation of landscape to reflect on how material and cultural processes affect stakeholders' perceptions of the Cairngorms National Park in Scotland, UK. Important to understanding different views, is the separation, unique to the Cairngorms, of ‘the park’ from its management organisation. The paper argues that this separation creates a conceptual space for the negotiation of contested claims regarding the park. Such claims reflect not only the relationship between people and place, or as Ingold (2000) puts it, the landscape as it is known to those who dwell in it; they also represent vested interests and regimes of power concerning what happens in specific places. These claims do not reproduce simple splits between, for example, public/private or conservation/development but show a more complex picture.     

Wind characteristics and energy potential assessment in Akure,South West Nigeria: econometrics and policy implications

This paper analysed 11 years of daily mean wind-speed data, measured at Akure, Ondo State, Nigeria, using Weibull and Rayleigh distribution functions. While both distributions showed good agreements in extreme-value estimation patterns, investigation of their wind-speed characteristics modelling criteria, using goodness-of-fit statistics, revealed that the wind data followed the Weibull more than Rayleigh. Monthly wind-speed of Akure city ranged from 1.41 to 4.24 m/s by the Weibull fittings and from 1.40 to 4.16 m/s by the Rayleigh fittings. Overall results, of 2.71 m/s (Weibull) or 2.70 m/s (Rayleigh) mean wind-speed and 18.51 W/m² (Weibull) or 22.26 W/m² (Rayleigh) mean power density, indicated Akure a low wind-speed site, requiring low wind-speed turbine for generating wind energy. Econometric analyses of power output simulations using such turbine system resulted in affordable wind energy cost. These bear policy implications for sustainable wind energy usage in this and similar regions of the world.     

Planning for population ageing: Ensuring enabling and supportive physical-social environments – Local infrastructure challenges

Ensuring enabling and supportive environments is a key global priority in planning for population ageing. This paper examines the challenges local governments face in creating age-friendly physical-social environments. Findings from a recent study of local government and ageing in New South Wales, Australia and subsequent research are reported. The analysis reveals that local councils have differing abilities to provide age-friendly local infrastructure. Challenges are greater overall for regional, rural and fringe councils compared to metropolitan. Timely provision is greatly constrained by insufficient resources, the large scale of the task and the low priority accorded, despite the immediate need for action. A pressing requirement is demonstrated for local councils to give primacy to population ageing in their long-term strategic, asset and financial planning, and to engage in reform measures to assist in financing the cost.     

Functionalized galactoglucomannan‐based hydrogels for the removal of metal cations from aqueous solutions

New types of hydrogels derived from O‐acetyl galactoglucomannan (AcGGM) hemicellulose have been synthesized and characterized. The objective of this work was to analyze the sorption capacity (S) of three types of hydrogels containing AcGGM derivatives incorporated into the carboxylic groups of the polymer chain in the AA hydrogel, sulfonic groups in the APA hydrogel, and amide groups in the acrylamide (Aam) hydrogel. These hydrogels are capable of interacting and removing ions such as cadmium [Cd(II)], copper [Cu(II)], lead [Pb(II)], nickel [Ni(II)], and zinc [Zn(II)]. The results show that AA and Aam hydrogels had a lower sorption capacity of ions compared to the APA hydrogel, which had a high sorption capacity. The maximal sorption capacity was determined by the successive enrichment method, obtaining Pb(II) amount of 48.3 mg/g of AA hydrogel, 65.8 mg/g of APA hydrogel, and 40.8 mg/g of Aam hydrogel. Hence, Pb(II) ions are greatly retained by the three hydrogels. These results are promising for the development of new materials with potential applications in metal ion removal. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016 , 133, 44093.
