Soil Organic Carbon Density in Hebei Province, China: Estimates and Uncertainty

In order to improve the precision of soil organic carbon (SOC) estimates, the sources of uncertainty in soil organic carbon density (SOCD) estimates and SOC stocks were examined using 363 soil profiles in Hebei Province, China, with three methods: the soil profile statistics (SPS), GIS-based soil type (GST), and kriging interpolation (KI). The GST method, utilizing both pedological professional knowledge and GIS technology, was considered the most accurate method of the three estimations, with SOCD estimates for SPS 10% lower and KI 10% higher. The SOCD range for GST was 84% wider than KI as KI smoothing effect narrowed the SOCD range. Nevertheless, the coefficient of variation for SOCD with KI (41.7%) was less than GST and SPS. Comparing SOCD’s lower estimates for SPS versus GST, the major sources of uncertainty were the conflicting area of proportional relations. Meanwhile, the fewer number of soil profiles and the necessity of using the smoothing effect with KI were its sources of uncertainty. Moreover, for local detailed variations of SOCD, GST was more advantageous in reflecting the distribution pattern than KI.

Principal Features of Building Social Accounts Matrix and Improving Statistical Database for Eco-countries

With common borders of the population, total area, and GDP （PPP-based） of Economic Cooperation Organization （ECO） member states are estimated as 416 million persons, 7.9 million m2, and US$2.7 trillion respectively （2010 data）. Although heterogeneous in the extent, there is economic development, overall, with serious energy and transport-transit relations among countries that is reflected in growing trade turnover year-by-year. However, there are still rather unused resources and capacity in such areas of cooperation among countries as exchange of energy, transport services, agricultural and industrial goods, use of opportunities for tourism, promoting investment and innovation processes and other areas. Certainly, maximum and optimal use of these resources calls for availability of analytical means capable of accounting for relations both within member states and among them. The implementation of computable general equilibrium （CGE） modeling in each member state would thus be of great significance in resolution of these problems both in terms of accounting for input-output linkages within the countries as well as enabling impact of main trading partners and goods and services among countries. The analysis carried out indicates that there are a number of problems in application of CGE model in most of the member states. As such, input-output tables are not compiled in some countries, while in others despite the fact that these tables are compiled, there are no attempts to build the model, yet in other countries, even if the CGE model is implemented, there are difficulties in taking into account the real results in the face of serious problems related to improving national accounts system database. Summarizing these problems, it is possible to conclude that to ensure the application of a CGE model,there is a great need to work out procedures of compilation of a social accounts matrix （SAM） that lies on the basis of this model, for which the relevant statistics of a member state must be improved. Considering the above-mentioned, the presented research, makes procedures and proposals on compilation of SAM, improves statistical data for researching the extent of application of CGE Model in ECO member states, and identifies the degree of availability and organization of relevant data to develop input-output tables and respective SAM.

Assessing the Impact of Year 2012 Drought on Corn Yield in the US Corn Belt Using Precipitation Data

Extreme weather and climate events are likely to cause disastrous consequences for agriculture and food security. This study investigated the impacts of drought in year 2012 on corn yield in the United States Corn Belt by integrating county-level crop yield data from the USDA NASS Quick Stats database and precipitation data from the NCDC GHCN-Daily database. It is found that precipitation over an 8-week period in corn growth stages is critical for corn yield, the logarithm of precipitation during the period explained 55% of corn yield variation. The results indicated the importance of water supply in corn silking stage, and provided an approach to assess the impacts of drought on corn yield quantitatively.

Analysis of Foreign Trade Among Slovakia and the Country V4 After the Changeover

The article presents the situation in foreign trade among Slovakia and the country V4 （Czech Republic, Hungary, Poland, and Slovak Republic） after the changeover in 2009. At a time of economic crisis, Slovakia acceded to the adoption of a common currency--the euro. Prior to the adoption of the euro, apprehensions were raised due to currency decreased export from Slovakia to countries V4. In this article, author analyses the mutual foreign trade of Slovakia with countries of V4 for all commodities in standard international trade classification （SITC） codes. The analysis covers the time before the adoption of the euro from 2004 to 2008 and after the adoption of the euro in the years from 2009 to 2013. It compares the percentage change over the previous year, the balance of foreign trade, and foreign trade turnover. The same analysis is also done for the period prior to the adoption of the euro as a whole and after the adoption of the euro. In the calculations, data from UN Comtrade Database were used, which are indicated in USD. The results indicate that in the transition to the common currency, the euro did not mean for Slovakia worsening trade with V4 countries. Economies of these countries have long been linked and even the possibility of its own monetary policy does not endanger Slovakia＇s export to these countries.

A Stylistic Analysis of Hemingway＇s News and Fiction Writing

Literature about Hemingway＇s writing style has been fully explored in the past 80 years, while his style has not yet been well probed into from the perspective of corpus-based stylistics. This paper focuses on the analysis of his writing style as a news reporter and as a literary writer in order to investigate whether there exists some links between the two or whether his training as a reporter has any effect on his writing as fiction writer. By employing a corpus-based stylistic approach, the paper analyzes in great details Hemingway＇s early news writing in Kansas City Star （ 1917-1918） and his later fiction writing in the novella The Old Man and the Sea （1952）. The stylistic features at lexical level are explored quantitatively in both writings via statistical data. The paper concludes that Hemingway＇s writing style has his own heritage. The style in his early news articles does find its way into his later fiction writing. There do exist certain similarities in the choices of lexical items and phrasal expressions. It also indicates that a further exploration on their syntactic, rhetorical, and discourse levels is needed ira fuller picture of Hemingway＇s writing style is to be unveiled.

Comparative Analysis of Modal Auxiliary Verbs in English and in Chinese

The study of modal auxiliary verbs has been done by comparing modal auxiliary verbs in English with the ones in Chinese qualitatively and quantitatively. The modals in English and in Chinese are statistically analyzed through their forms and meanings. The data consists of 50 pieces of Chinese prose with their 50 English translation versions called corpus A and 50 pieces of English prose with their Chinese translation versions called corpus B, altogether 200 articles, which represent a type of discourse that is rich in modal auxiliary verbs both in English and in Chinese The major findings are as follows： （1） The three criteria： inversion, negation, and the use of pro-forms can be used to define both English and Chinese auxiliaries; （2） the modals of both languages can be analyzed within the same semantic categories： volition, probability, and necessity; （3） Chinese epistemic modals can have inversion patterns; （4） the negative forms of Chinese modals are more complex than those of English modals; and （5） the statistic analysis shows that the modals in probability category both in English and in Chinese are used much more often compared to the other two categories： volition and necessity and that deontic modals are used much fewer in both languages to express necessity

Multi-Level Cryptographic Functions for the Functionalities of Open Database System

The purpose of this paper is to design and implement a secure open database system for organizations that are increasingly opened up their information for easy access by different users. The work proposed some functionalities such as open password entry with active boxes, combined encryption methods and agent that can be incorporated into an open database system. It designed and implemented an algorithm that would not allow users to have free access into open database system. A user entering his password only needs to carefully study the sequence of codes and active boxes that describe his password and then enter these codes in place of his active boxes. The approach does not require the input code to be hidden from anyone or converted to place holder characters for security reasons. Integrating this scheme into an open database system is viable in practice in term of easy use and will improve security level of information.

Vaccination Statistics and Reality： How Many Horses Are Really Vaccinated against Equine Influenza？

Standard schedules for equine influenza vaccinations have been published in Finland. However, no knowledge about the actual number of vaccinations has been available. Based on previous preliminary studies in slaughterhouses and among horse owners, it was suspected that vaccination recommendations are not always followed. The aims were to investigate vaccination status against equine influenza among Finnish racehorses in regional competitions. Vaccination status was investigated： （1） by utilizing database vaccination information of show jumping and dressage horses and （2） by carrying out a survey among horse industry experts. A total of 400 horses were selected at the beginning of the Finnish competition season in 2012 and five experts （key persons） were invited to a repeated survey implemented by Delphi techniques. Overall, 50%-100% of horses were properly vaccinated depending on the source available. Thirty-four percent （34%） of the horses had the competition license but no vaccination markings in the database. Differences between types of competition （show jumping and dressage） and between Southern and Northern parts of Finland were found. Vaccinations of show jumping horses were registered more often than vaccinations of dressage horses. Ninety percent （90%） of unvaccinated horses in the database were eight years or older. It can be concluded that equine influenza vaccination registry coverage among racehorses in Finland is incomplete. This poses a risk of misunderstanding, and the growing responsibility of competition organizers.
