Context Worldwide, invasive vertebrate eradication campaigns are increasing in scale and complexity, requiring improved decision making tools to achieve and validate success. For managers of these campaigns, gaining access to timely summaries of field data can increase cost-efficiency and the likelihood of success, particularly for successive control-event style eradications. Conventional data collection techniques can be time intensive and burdensome to process. Recent advances in digital tools can reduce the time required to collect and process field information. Through timely analysis, efficiently collected data can inform decision making for managers both tactically, such as where to prioritise search effort, and strategically, such as when to transition from the eradication phase to confirmation monitoring. Aims We highlighted the advantages of using digital data collection tools, particularly the potential for reduced project costs through a decrease in effort and the ability to increase eradication efficiency by enabling explicit data-informed decision making. Methods We designed and utilised digital data collection tools, relational databases and a suite of analyses during two different eradication campaigns to inform management decisions: a feral cat eradication utilising trapping, and a rodent eradication using bait stations. Key results By using digital data collection during a 2-year long cat eradication, we experienced an 89% reduction in data collection effort and an estimated USD42 845 reduction in total costs compared with conventional paper methods. During a 2-month rodent bait station eradication, we experienced an 84% reduction in data collection effort and an estimated USD4525 increase in total costs. Conclusions Despite high initial capital costs, digital data collection systems provide increasing economics as the duration and scale of the campaign increases. Initial investments can be recouped by reusing equipment and software on subsequent projects, making digital data collection more cost-effective for programs contemplating multiple eradications. Implications With proper pre-planning, digital data collection systems can be integrated with quantitative models that generate timely forecasts of the effort required to remove all target animals and estimate the probability that eradication has been achieved to a desired level of confidence, thus improving decision making power and further reducing total project costs.

Objective: To establish feasibility of initiating electrical stimulation treatment of wrist extensors and flexors in patients early after stroke to prevent muscle contractures and pain. Design: Feasibility randomized controlled trial with economic evaluation. Setting: A specialist stroke unit in Nottinghamshire. Subjects: A total of 40 patients recruited within 72 hours post-stroke with arm hemiparesis. Interventions: Participants were randomized to receive usual care or usual care and electrical stimulation to wrist flexors and extensors for 30 minutes, twice a day, five days a week for three months. Initial treatment was delivered by an occupational therapist or physiotherapist who trained participants to self-manage subsequent treatments. Measures: Measures of feasibility included recruitment and attrition rates, completion of treatment, and successful data collection. Outcome data on wrist range of motion, pain, arm function, independence, quality of life, and resource use were measured at 3-, 6-, and 12-months post-randomization. Results: A total of 40 participants (of 215 potentially eligible) were recruited in 15 months (20 men; mean age: 72 (SD: 13.0)). Half the participants lacked mental capacity and were recruited by consultee consent. Attrition at three-month follow-up was 12.5% (death ( n = 2), end-of-life care ( n = 2), and unable to contact ( n = 1)). Compliance varied (mean: 65 (SD: 53)) and ranged from 10 to 166 treatments per patient (target dosage was 120). Data for a valid economic analysis can be adequately collected. Conclusion: Early initiation of electrical stimulation was acceptable and feasible. Data collection methods used were feasible and acceptable to participants. A large definitive study is needed to determine if electrical stimulation is efficacious and cost effective.

Quality Response

Cost effective data collection is an important methodological issue for small and medium enterprise (SME) researchers. There is a generally held view that mail surveys are the most efficient means of collecting empirical data, despite the potential difficulties associated with low response rates. To enhance the usefulness of mail surveys, researchers have suggested a variety of strategies aimed at improving response rates. While previous studies have examined the effect on response rates of many of these strategies, their impact on data quality and on the cost effectiveness of data collection is less well understood. This study evaluates four response–inducing strategies (printing the survey instrument on colored paper, telephone pre–notification, payment of a monetary incentive, and a follow–up mailing) in terms of their effect on data quality, response rates, and cost effectiveness for a population of SMEs.

Loss of subjects during follow-up is a frequent occurrence in outcome research on habit disorders. This attrition may have undesirable effects on statistical power, effect-size estimation, and causal inferences. The present study investigated the effects of offering subjects a monetary incentive of $0.00, $5.00, or $15.00 as a cost effective alternative to normal follow-up procedures for attending a scheduled follow-up meeting. The results indicate that these modest incentives did not significantly enhance attendance at the follow-up visit. Suggestions for future applications of monetary incentives in follow-up data collection are provided.

Collecting research data through traditional approaches (face-to-face, postal or telephone survey) can be costly and time consuming. The emerging data collection approach based on internet/e-based technologies (e.g. online platforms and email), is a relatively cost effective survey alternative. These novel data collection strategies can collect large amounts of data from participants in a short time frame. Similarly, they also seem to be feasible and effective in collecting data on sensitive issues or with samples they are generally hard to reach, for example, men who have sex with men (MSM) or migrants. As a significant proportion of the population currently in the world are digitally connected, the shift from postal (paper-pencil) or telephone towards online survey use in research is in the interests of researchers in academia as well as in the commercial world. However, compared to designing and executing paper version of the questionnaire, there is limited literature to help a starting researcher with the design and a use of online questionnaires. This short paper highlights issues around: a) methodological aspect of online questionnaire survey; b) online survey planning and management; and c) ethical concerns that may arise while using this option. We believe that this paper will be useful for researchers who want to gain knowledge or apply this approach in their research.

This study assessed the effectiveness of participatory video and drama in enhancing learning of climate-smart push-pull technology in western Kenya. A total of 80 farmers who had no knowledge of push pull technology were exposed to participatory drama and video that had been developed by farmers who are adopting push pull technology. Validated questionnaires were used for data collection where sampled non push pull farmers were interviewed before and after exposure to push pull knowledge using participatory video and drama. Data obtained was analyzed using chi square at 0.05 confidence level set a priori and also presented using frequency tables, percentages, charts and averages relevant. Results show that the effectiveness of participatory video and drama in disseminating   push pull content is significantly differentiated by the type or component of the push pull knowledge being disseminated. For instance, among farmers exposed to drama, 38.4% were rated as average and good in their understanding of Push Pull concepts, descriptions and definitions compared 19.2% for farmers exposed to participatory video (χ^2=15.949, p0.05). This is completely different for push pull knowledge contents of “establishment and management of Push pull fields”, where among farmers exposed to video,46.1% were rated as good and average compared to 28.2% who were exposed to drama (χ^2=10.1921, p=5). The study concludes that while both methods are cost effective, drama is more effective in  the attraction of larger crowd ,ignition of initial  interest  and educating farmers  on  minimum basics of push pull technology .Participatory video does better in explaining deeper details of push pull knowledge where farmers need not only to hear of the technology but also to adopt it .However no single dissemination method can work perfectly alone, whereas drama can be used as an introductory in attracting the crowd and teaching the basic technological knowledge of push pull technology, this knowledge can be affirmed for purposes of actual adoption by other dissemination methodologies like   participatory video.

AbstractEngineering of microbial cells to produce high value chemicals is rapidly advancing. Yeast, bacteria and microalgae are being used to produce high value chemicals by utilizing widely available carbon sources. However, current extraction processes of many high value products from these cells are time- and labor-consuming and require toxic chemicals. This makes the extraction processes detrimental to the environment and not economically feasible. Hence, there is a demand for the development of simple, effective, and environmentally friendly method for the extraction of high value chemicals from these cell factories. Herein, we hypothesized that atomically thin edges of graphene having ability to interact with hydrophobic materials, could be used to extract high value lipids from cell factories. To achieve this, array of axially oriented graphene was deposited on iron nanoparticles. These coated nanoparticles were used to facilitate the release of intracellular lipids from Yarrowia lipolytica cells. Our treatment process can be integrated with the growth procedure and achieved the release of 50% of total cellular lipids from Y. lipolytica cells. Based on this result, we propose that nanoparticles coated with axially oriented graphene could pave efficient, environmentally friendly, and cost-effective way to release intracellular lipids from yeast cell factories.

Huanglongbing, or citrus greening, is a global citrus disease occurring in almost all citrus growing regions and causing substantial economic burdens to individual growers, citrus industries and governments. Successful management strategies to reduce disease burden are desperately needed but with so many possible interventions and combinations thereof, it is difficult to know which are worthwhile or cost-effective. We review how mathematical models have yielded useful insights into controlling disease spread for other vector-borne plant diseases, and the small number of mathematical models of Huanglongbing. We adapt a malaria model to Huanglongbing, by including temperature-dependent psyllid traits and economic costs, to show how models can be used to highlight which parameters require more data collection or which should be targeted for intervention. We analyze the most common intervention strategy, insecticide spraying, to determine the most cost-effective spraying strategy. We found that fecundity and feeding rate of the vector require more experimental data collection, for wider temperatures ranges. The best strategy for insecticide intervention was to spray for more days rather than pay extra for a more efficient spray. We conclude that mathematical models are able to provide useful recommendations for managing Huanglongbing spread.
