How Do You Build A Community? Developing Community Capacity And Social Capital In An Urban Aboriginal Setting

Previous literature has identified social capital as an important resource for successful community development activities, and there have been some attempts to adapt the concepts of social capital to the particular context of First Nations. However, little information is available about how social capital itself might be developed or improved in Aboriginal communities. Moreover, urban Aboriginal communities are different from rural First Nations, Inuit or Métis communities in structure, composition, activities, and diversity, and deserve specific attention and their own models of community development. This paper presents a framework to guide development initiatives in urban Aboriginal contexts that is drawn from Aboriginal cultural principles and connected to the academic literature on development and social capital. Intended to provide practical advice to community leaders and practitioners, the framework includes five “tenets”: strategic planning; Elders and children; prayers and medicines; responsibility and ownership; and mentoring and role modelling

A molecular dynamics study of the thermal properties of thorium oxide

There is growing interest in the exploitation of the thorium nuclear fuel cycle as an alternative to that of uranium. As part of a wider study of the suitability of thorium dioxide (thoria) as a nuclear fuel, we have used molecular dynamics to investigate the thermal expansion, oxygen diffusion, and heat capacity of pure thoria and uranium doped (1-10%) thoria between 1500K and 3600 K. Our results indicate that the thermal performance of the thoria matrix, even when doped with 10%U, is comparable to, and possibly better than, that of UO2

Collaborative public health system interventions for chronic disease prevention among Urban Aboriginal peoples

Urban Aboriginal peoples are at higher risk to a variety of chronic diseases, compared with other Canadians. Social determinants of health, socio-ecological approaches to health, and life course perspectives can identify some of the various factors that contribute to this excess risk. The complexity of these factors suggests that an effective strategy for reducing this risk might be to focus on improving the capacity of the local public health system that serves Aboriginal people and families, rather than on interventions aimed solely at individual health behaviour change. This article uses the Healthy Weights Connection intervention as an example of one of several systems-focussed and collaborative approaches to improving the health of urban Aboriginal people. Despite their potential utility, we suggest that there are unique considerations for implementing and evaluating such interventions in an urban Aboriginal context

Listeners’ Spectral Reallocation Preferences for Speech in Noise

Modifying the spectrum of recorded or synthetic speech is an effective strategy for boosting intelligibility in noise without increasing the speech level. However, the wider impact of changes to the spectral energy distribution of speech is poorly understood. The present study explored the influence of spectral modifications using an experimental paradigm in which listeners were able to adjust speech parameters directly with real-time audio feedback, allowing the joint elicitation of preferences and word recognition scores. In two experiments involving full-bandwidth and bandwidth-limited speech, respectively, listeners adjusted one of eight features that altered the speech spectrum, and then immediately carried out a sentence-in-noise recognition task at the chosen setting. Listeners’ preferred adjustments in most conditions involved the transfer of speech energy from the sub-1 kHz region to the 1–4 kHz range. Preferences were not random, even when intelligibility was at the ceiling or constant across a range of adjustment values, suggesting that listener choices encompass more than a desire to maintain comprehensibility.Olympia Simantiraki was funded by the European Commission under the Marie Curie European Training Network ENRICH (675324)

ALTERNATIVE COTTON PRODUCTION SYSTEMS

Mississippi cotton farmers are adjusting to the current problem of low cotton price and high cotton production cost by modifying the way(s) they have traditionally grown cotton. This paper compares seven alternative production systems to the costs and returns associated with the conventional or traditional system labeled "solid cotton, 8-row equipment." Systems that combine wider equipment (less labor and machinery time per acre) with reduced tillage technology appear to offer opportunities to increase returns. Specific adjustments on individual farms will probably be dominated by the distribution of soil types.conservation tillage, ultra-narrow, no-till, skip-row, costs, returns, Production Economics,

Non-native consonant acquisition in noise: Effects of exposure/ test similarity

When faced with speech in noise, do listeners rely on robust cues or can they make use of joint speech-plus-noise patterns based on prior experience? Recent studies have suggested that listeners are better able to identify words in noise if they experienced the same word-in-noise tokens in an earlier exposure phase. The current study examines the role of token similarity in exposure and test conditions. In three experiments, Spanish learners of English were exposed to intervocalic consonants during an extensive training phase, bracketed by pre- and post-tests. Distinct cohorts experienced tokens that were either matched or mismatched across test and training phases in one or both of two factors: signal-to-noise ratio (SNR) and talker. Cohorts with fully matching test-training exposure were no better at identifying consonants at the post-test phase than those trained in partially or fully mismatched conditions. Indeed, at more adverse test SNRs, training at more favourable SNRs was beneficial. These findings argue against the use of joint speech-plus-noise representations at the segmental level and instead suggest that listeners are able to extract useful acoustic-phonetic information across a range of exposure conditions.This study was carried with funding from the Basque Government Consolidados grant to the Language and Speech Laboratory at the University of the Basque Country
