Remote sensing technologies have been advanced continuously to a certain level for multi-scale applications to ease social and political concerns resulting from food security. In this study, an integrated monitoring, sensing and modeling system for estimating CO2 fixation and grain yields using a photosynthetic sterility model was developed. Input data for model computation include observed meteorological data, numerical prediction reanalysis data, and satellite data such as solar radiation, land-cover and Normalized Difference Vegetation Index (NDVI) on a continental scale. Model validation requires crop yields and the Crop Situation Index (CSI) was provided by the Japanese government. It also demonstrates the application potential of this system to grain fields of paddy rice, winter wheat, and maize in Southeast Asia. The carbon hydrate in grains has the same chemical formula as that of cellulose in grain vegetation. The partition of sequestered CO2 into grain, straw, and root portions of plant biomass weight was computed. The present photosynthesis model was evaluated using the mass of carbon included in the harvested grains of provincial crop production. Results indicate that the proposed system successfully estimates the photosynthesis fixation of rice reasonably well in Japan and China through the analysis of carbon in grains. However, the model tends to underestimate the photosynthesis rates for winter wheat and maize. The parameterization of radiation response function and the temperature response functions for low-temperature sterility need to be improved in the future. © 2010 Elsevier B.V.

Sustainability of world crop production and food security has become uncertain. The authors have developed an environmental research system called Remote Sensing Environmental Monitor (RSEM) for treating carbon sequestration by vegetation, grain production, desertification of Eurasian grassland, and CDM afforestation/ reforestation to a background of climate change and economic growth in rising Asian nations. The RSEM system involves vegetation photosynthesis and crop yield models for grains, including land-use classification, stomatal evaluation by surface energy fluxes, and daily monitoring for early warning. This paper presents a validation method for RSEM based on carbon partitioning in plants, focusing in particular on the effects of area sizes used in crop production statistics on carbon fixation and on sterility-based corrections to accumulated carbon sequestration values simulated using the RSEM photosynthesis model. The carbonhydrate in grains has the same chemical formula as cellulose in grain plants. The method proposed by partitioning the fixed carbon in harvested grains was used to investigate estimates of the amounts of carbon fixed, using the satellite-based RSEM model. © 2010 Copyright SPIE - The International Society for Optical Engineering.

As the proliferation of e-commerce leads to ever greater numbers of on-line transactions, transportation planners are interested in the impacts of e-shopping on our strained transportation systems. Although the substitution effect of e-shopping is appealing, previous studies provided mixed results on its impact. Using 539 adult internet users in the Minneapolis-St Paul metropolitan area, this study applied a structural equations model to investigate the interactions among online purchases, in-store shopping, and product information search via internet. We found that online searching frequency has positive impacts on both online and in-store shopping frequencies and online buying positively affects in-store shopping. In particular, the marginal effects of online-buying frequency and online-searching frequency on in-store shopping frequency were estimated at 0.153 and 0.189, respectively. Since the internet as a shopping channel tends to have a complementary effect on in-store shopping, the rise of e-shopping is not likely to be a solution but a challenge to travel reduction. © 2011 Springer Science+Business Media, LLC.

The author regards fundamental root functions as underpinning photosynthesis activities by vegetation and as affecting environmental issues, grain production, and desertification. This paper describes the present development of monitoring and near real-time forecasting of environmental projects and crop production by approaching established operational monitoring step-by-step. The author has been developing a thematic monitoring structure (named RSEM system) which stands on satellite-based photosynthesis models over several continents for operational supports in environmental fields mentioned above. Validation methods stand not on FLUXNET but on carbon partitioning validation (CPV). The models demand continuing parameterization. The entire frame system has been built using Reanalysis meteorological data, but model accuracy remains insufficient except for that of paddy rice. The author shall accomplish the system that incorporates global environmental forces. Regarding crop production applications, industrialization in developing countries achieved through direct investment by economically developed nations raises their income, resulting in increased food demand. Last year, China began to import rice as it had in the past with grains of maize, wheat, and soybeans. Important agro-potential countries make efforts to cultivate new crop lands in South America, Africa, and Eastern Europe. Trends toward less food sustainability and stability are continuing, with exacerbation by rapid social and climate changes. Operational monitoring of carbon sequestration by herbaceous and bore plants converges with efforts at bio-energy, crop production monitoring, and socio-environmental projects such as CDM A/R, combating desertification, and bio-diversity. © 2013 SPIE.

So much of conversion rate optimization relies on testing. “Test everything, test often” is a good mantra to keep in mind and will do you no end of good. But you can’t always test everything. In this post I discuss a few ways you might be able to uncover some of those conversion leaks that you might not even have been aware of before. This is often a hidden issue with sites which receive traffic from multiple languages/countries. Even if you have multiple language websites or multi-lingual sections on your site to help users, you need to check that visitors are using the right language section pages on your site. If they’re not then you might run into troubles. For example, take a look at this screenshot of analytics data from an international company. This is their UK, 100% English content: In this situation there’s a very strong business case for not letting those little language selection links at the top of the page do all the work—you should consider investing in some geo-based redirection technology to take your non-English users straight to the correct language content. Email marketing is a big topic, and an important component of many online marketing campaigns. Often overlooked is that you shouldn’t just consider email marketing as a once/month push (or once/week etc)—you should consider setting up an auto-schedule of emails for new sign-ups to your site. As soon as a new user enters onto your email list they should enter a cycle of emails which get sent out—above and beyond the initial email. I’m not talking about spamming but some helpful emails can really help users convert. Pingdom does this very well—I signed up for a free trial of their tool and after a week or so I received an email asking if I was ok with everything on the service, asking if I had any questions etc. This kind of thing will help turn those passive users into active users and hopefully customers. This is web best practice anyway but you should always keep an eye on website issues, whether they’re 404 errors, site downtime (Pingdom has a good tool for this, see above!) or something else. Analytics packages don’t always monitor these things by default so this kind of traffic can often be overlooked. Imagine the (nonexistent) conversion rate of users who see a 404 page! So cleaning up these 404 errors and taking users to a better page can help to increase conversions. If you don’t have big development resources, Google Webmaster Central can help identify 404 errors on your site. If Google is seeing these errors then there’s a good chance that users are too. If you’re running a dynamic site that runs off an ever-changing database then you should also monitor carefully for situations where a user hits a sub-optimal page. It might not be a true 404 error but if for example you have a dynamic product database then you should look out for any visits to category pages with zero products on. These kinds of hidden errors can often be a source of lost conversions. In the land of the blind the one-eyed man is king, but in the land of the internet the man with most data is king. So alongside testing your website consider adding some extra data collection to inform your next test. A great place to start is with tracking how far users get through forms. My colleague Duncan Morris wrote a great post on how to easily do this using Google Analytics events. The best thing about that post? It works on any form using auto-binding!
