And Performance

Over the last 20 years, dew harvesting has evolved to fruition because of a better understanding of its physics, thermodynamics, and the radiative cooling process of condensing substrates. Although resultant yields are relatively small, dew positions itself as a viable water resources supplement because it occurs naturally and frequently in many locations globally, particularly in the absence of precipitation or when more traditional water sources are subject to depletion. Moreover, dew water is generally potable, especially in rural locations, where it is most beneficial. This review summarizes dew harvesting research achievements to date including formation processes, collection in various environments, prediction models, water quality, and applications. The paper concludes with outlining existing gaps and future research needs to improve the understanding and performance of dew harvesting in the context of adaptation to climate change.

Market Values

Abstract Although numerous and varied users harvest, trade, and consume nontimber forest products (NTFPs), relatively little is known about the organization of the markets for these products and the market value or contribution to local and regional economies. In this article, we review and synthesize economic research and information on the markets and market values of NTFPs in the United States. We describe formal and informal markets for NTFPs, and the extent to which and reasons why many of the details of these markets remain unknown to researchers and decisionmakers. We provide examples of the market values of various species and identify information gaps and research needs to improve resource management and increase economic development.

With the continuous publication of Guodian bamboo-slip manuscripts, Shanghai Museum bamboo-slip manuscripts and Tsinghua University bamboo-slip manuscripts, the study of Warring States bamboo-slip manuscripts has become a new research focus in recent years. Exegesis study is one of the most important aspects in bamboo-slip manuscripts research. As can be seen from those exegesis study results, it is found that some of them are widely accepted. However, some results are debateable. Furthermore, in many cases it is difficult to provide clear answers in exegesis study. Therefore, it is necessary to summarize the exegesis methods of these accepted and debateable results. Also, theoretical guidance for future research needs to be provided. This article will discuss applying traditional exegesis methods into exegesis study. Then it will discuss applying the special features of Warring States bamboo-slip manuscripts into exegesis study. Finally, it will discuss some problems which should be emphasized in exegesis study.

Research needs for the management of water quality issues, particularly phosphorus and oxygen concentrations, related to salmonid cage aquaculture in Canadian freshwaters

The Difference

A growing awareness of the difference between the supply and demand for fish products is fueling rapid growth of an aquaculture industry in Canada, including a freshwater sector, based mainly on the cage farming of rainbow trout. Cage farms can release relatively large loads of organic matter and nutrients to the environment. In consequence, federal and provincial resource management agencies need to develop regulatory instruments that will foster the growth of the industry while ensuring minimal water quality impacts. Such instruments should be science based, but there are currently key gaps in our understanding of the water quality implications of the operations of freshwater cage aquaculture. Here I review the state of science of the water quality implications of cage aquaculture and identify 11 knowledge gaps that currently hamper the development of sound, science-based cage culture management instruments. Perhaps the most important finding of the review is the recognition that, while aquaculture has produced significant increases in lakewater total phosphorus (TP) levels in some situations, classic phosphorus mass balance models may substantially overestimate the contributions of cage farms to TP concentrations in some lakes. Research on this, and perhaps the other knowledge gaps identified in this review, should aid the development of sound management instruments for freshwater cage aquaculture in Canada and elsewhere. Key words: aquaculture, cage culture, water quality issues, phosphorus, BOD, review, research needs, freshwaters.

Abstract. The major challenge for achieving a sustainable future for water resources and water security is the integration of water availability, water quality and water governance. Water is unevenly distributed on Planet Earth and these disparities are cause of several economic, ecological and social differences in the societies of many countries and regions. As a consequence of human misuse, growth of urbanization and soil degradation, water quality is deteriorating continuously. Key components for the maintenance of water quantity and water quality are the vegetation cover of watersheds, reduction of the demand and new water governance that includes integrated management, predictive evaluation of impacts, and ecosystem services. Future research needs are discussed.

In Infants And Children

The effectiveness of amplification for infants and children can be mediated by how much the child uses the device. Existing research suggests that establishing hearing aid use can be challenging. A wide range of factors can influence hearing aid use in children, including the child's age, degree of hearing loss, and socioeconomic status. Audiological interventions, including using validated prescriptive approaches and verification, performing on-going training and orientation, and communicating with caregivers about hearing aid use can also increase hearing aid use by infants and children. Case examples are used to highlight the factors that influence hearing aid use. Potential management strategies and future research needs are also discussed.

Self Confidence

Locus of control (LOC), safety attitudes, and involvement in hazardous events were studied in 205 Indian Army aviators using a questionnaire-based method. A positive correlation was found between external LOC and involvement in hazardous events. Higher impulsivity and anxiety, and decreased self-confidence, safety orientation, and denial were associated with a greater number of hazardous events. Higher external LOC was associated with higher impulsivity, anxiety, and weather anxiety and with lower self-confidence, safety orientation, and denial. Internal LOC was associated with increased self-confidence, safety orientation, and denial. Hazardous events and self-confidence were higher in those involved in accidents than those not involved in accidents. Future research needs to address whether training can effectively modify LOC and negative attitudes, and whether this would cause a reduction in, and better management of, human errors.
