Industry's Response to the Green Movement
Little, Barry F.P. 한국분석과학회 1995 분석과학 Vol.8 No.4
This paper describes how industry has responded to the environmental challenge. Benefits include compliance with environmental legislation; genuine reductions to environmental impact; sustainable improvements to profitability in the face of increased competitive pressure. National and international Standards for environmental management offer security and direction for a company wishing to improve environmental performance and coupled with a waste minimisation strategy many financial and environmental benefits can be achieved. Introduction of new technical skills, techniques and worker understanding to aid motivation is an essential component of such a strategy. Monitoring and targeting has a key role to play in the establishment of improved environmental performance.
Antibacterial compounds in green microalgae from extreme environments: a review
Little, Shannon M.,Senhorinho, Gerusa N.A.,Saleh, Mazen,Basiliko, Nathan,Scott, John A. The Korean Society of Phycology 2021 ALGAE Vol.36 No.1
Increased proliferation of bacterial resistance to antibiotics is a critical issue that has increased the demand for novel antibacterial compounds. Antibacterial activities have been evaluated in extracts from photosynthetic green microalgae, with varying levels of subsequent potential for development based on the strain of algae, strain of bacterial pathogen, and solvent used to extract the metabolites. Green microalgae from extreme environmental conditions have had to adapt to conditions that exclude many other organisms. The production of antibacterial compounds aids directly or indirectly in the survival of green microalgae in these extreme environments, as well as potentially serve other roles. This review investigates antibacterial activities of green microalgae from both extreme in-situ environmental conditions and induced extreme laboratory conditions and highlights.
Risk, Challenge and Safety in Outdoor Play: Pedagogical and Regulatory Tensions
Helen Little 환태평양유아교육연구학회 2010 Asia-Pacific journal of research in early childhoo Vol.4 No.1
Early Childhood services are becoming an increasingly significant part of children’s lives. As such they offer vital opportunities for children to engage in physically challenging active play in a safe and secure environment. However, in an increasingly ‘risk averse’ society an over-emphasis on safety has seen such play opportunities eroded. This qualitative study explored Early Childhood practitioners’ (n = 17) beliefs about risk-taking and their provision of ‘risky’ play opportunities in the outdoor environment. The findings suggest that from a pedagogical perspective, practitioners believe opportunities for risk-taking are important for all aspects of children’s development however the regulatory environment places constraints on their ability to provide sufficiently challenging experiences. The research findings support the call for more flexible enforcement of regulations to allow practitioners to use their professional knowledge to make informed decisions in risk situations.

Background: Cancer survivors have a high rate of participation in cigarette-smoking cessation programs but their smoking-abstinence rates remain low. In the current study, we evaluated the readiness to quit smoking in a cancer-survivor population. Methods: Cross-sectional data survey conducted among 112 adult cancer survivors who smoked cigarettes in Tennessee. Analyses were conducted using a two-sample t-test, χ2 test, Fishers Exact test, and multivariable logistic regression with smoker’s readiness to quit as the dependent variable. We operationally defined a smoker not ready to quit as anyone interested in quitting smoking beyond the next 6 months or longer (or not at all), as compared to those that are ready to quit within the next 6 months. Results: Thirty-three percent of participants displayed a readiness to quit smoking in the next 30 days. Smokers ready to quit were more likely to display high confidence in their ability to quit (OR = 4.6; 95% CI, 2.1-9.7; P < 0.0001) than those not ready to quit. Those ready to quit were nearly five times more likely to believe smoking contributed to their cancer diagnosis (OR = 4.9; 95% CI, 1.1-22.6; P = 0.0432). Those ready to quit were also much more likely to attempt smoking cessation when diagnosed with cancer (OR = 8.9; 95% CI, 1.8-44.3; P = 0.0076) than smokers not ready to quit. Finally, those ready to quit were more likely to endorse smoking more in the morning than other times of the day, compared to those not ready to quit (OR = 7.9; 95% CI, 1.5-42,3; P = 0.0148), which increased odds of readiness to quit within the next 6 months. Conclusions: Despite high participation in smoking-cessation programs for cancer survivors, only one-third of participants were ready to quit. Future research is needed to develop programs targeting effective strategies promoting smoking cessation among cancer survivors who are both ready and not ready to quit smoking.

A REVIEW OF EJECTOR TECHNOLOGY FOR REFRIGERATION APPLICATIONS
ADRIENNE B. LITTLE,SRINIVAS GARIMELLA 대한설비공학회 2011 International Journal Of Air-Conditioning and Refr Vol.19 No.1
This paper provides a comprehensive review of ejector technology for refrigeration applications, combining an understanding of basic fluid flow fundamentals within the ejector with application in cycle-level development. An ejector is a passive device that requires no external mechanical input or moving parts. A high-velocity motive stream produces a low-pressure region into which a suction flow is entrained, resulting in a pressure rise of the suction flow and mixing between the two streams to provide a pumping effect. The first part of this review addresses the progression from experiment-based analytical models to computational modeling of the ejector itself from the early 1950s to 2009. Included is an assessment of the most recent work in CFD modeling, and an exploration into what is needed to develop these models further. Suggestions for future research include better modeling of shock phenomena and the effects of two-phase flow in ejectors. The second part of this review focuses on ejector applications in refrigeration cycles with special emphasis on the vapor-jet refrigeration cycle. Important connections are made between ejector component and system level studies, an understanding of which would enable improvement of system level performance to the extent where they could be used in some niche applications instead of conventional refrigeration systems.
