Polymers from renewable resources have been used for a long time in biomedical applications and found an irreplaceable role in some of them.Their uses have been increasing because of their attractive properties,contributing to the improvement of life quality,mainly in drug release systems and in regenerative medicine.Formulations using natural polymer,nano and microscale particles preparation,composites,blends and chemical modification strategies have been used to improve their properties for clinical application.Although many studies have been carried out with these natural polymers,the way to reach the market is long and only very few of them become commercially available.Vegetable cellulose,bacterial cellulose,chitosan,poly(lactic acid)and starch can be found among the most studied polymers for biological applications,some with several derivatives already established in the market,and others with potential for such.In this scenario this work aims to describe the properties and potential of these renewable polymers for biomedical applications,the routes from the bench to the market,and the perspectives for future developments. 展开更多

Black-Scholes Model (B-SM) simulates the dynamics of financial market and contains instruments such as options and puts which are major indices requiring solution. B-SM is known to estimate the correct prices of European Stock options and establish the theoretical foundation for Option pricing. Therefore, this paper evaluates the Black-Schole model in simulating the European call in a cash flow in the dependent drift and focuses on obtaining analytic and then approximate solution for the model. The work also examines Fokker Planck Equation (FPE) and extracts the link between FPE and B-SM for non equilibrium systems. The B-SM is then solved via the Elzaki transform method (ETM). The computational procedures were obtained using MAPLE 18 with the solution provided in the form of convergent series. 展开更多

Tolerance of carrot and red beet to s-metolachlor at three application timings—pre-emergence to crop (PRE), early postemergence (crop at two to four leaf stage-EPOST), and late postemergence (crop at five to seven leaf stage-LPOST) —was determined from 2008 to 2010. LPOST applications of s-metolachlor reduced carrot above ground plant dry weight, marketable yield and grower payment, but did not affect carrot length. PRE and LPOST applications of s-metolachlor reduced red beet above ground plant dry weight, total marketable yield, yield of No. 2 and No. 3 red beet, and grower payment. Our findings indicate that while carrot may be tolerant to PRE applications of s-metolachlor, applications made after the 5 leaf stage reduced plant dry weight enough to impact marketable yield and grower payment. In red beet, the potential reduction in growth, yield and grade would not justify the utility of a PRE or LPOST applica- tion timing. 展开更多

LDL-factorization is an efficient way of solving Ax = b for a large symmetric positive definite sparse matrix A. This paper presents a new method that further improves the efficiency of LDL-factorization. It is based on the theory of elimination trees for the factorization factor. It breaks the computations involved in LDL-factorization down into two stages: 1) the pattern of nonzero entries of the factor is predicted, and 2) the numerical values of the nonzero entries of the factor are computed. The factor is stored using the form of an elimination tree so as to reduce memory usage and avoid unnecessary numerical operations. The calculation results for some typical numerical examples demonstrate that this method provides a significantly higher calculation efficiency for the one-to-one marketing optimization algorithm. 展开更多

This research aims to improve the efficiency in estimating the Hurst exponent in financial time series.A new procedure is developed based on equality in distribution and is applicable to the estimation methods of the Hurst exponent.We show how to use this new procedure with three of the most popular algorithms(generalized Hurst exponet,total triangles area,and fractal dimension)in the literature.Findings show that this new approach improves the accuracy of the original methods,mainly for longer series.The second contribution of this study is that we show how to use this methodology to test whether the series is self-similar,constructing a confidence interval for the Hurst exponent for which the series satisfies this property.Finally,we present an empirical application of this new procedure to stocks of the S&P500 index.Similar to previous contributions,we consider this to be relevant to financial literature,as it helps to avoid inappropriate interpretations of market efficiency that can lead to erroneous decisions not only by market participants but also by policymakers. 展开更多

For the last two decades, there has been an ongoing research concerning the international new ventures (INV) or born global (BG) companies which are rapidly entering foreign markets. They face challenges connected with their marketing activity, because they launch relatively more product innovations in a shorter time than the gradually internationalized companies (GRAD). The entrepreneurial marketing (EM) concept could become a solution to some of these challenges, because of a greater entrepreneurial intensity (EI) and different decision-making approach than "classical" marketing concept. This study's aim is to analyze the EM concept and application of its elements by the INVs originating from Poland. Based on two computer-aided telephone interview (CATI) studies of INVs from the Polish industrial processing sector, the central elements of EM, applied by them, are explored, together with their relationship to INV performance. As it is shown, the INVs introduce significantly more product innovations than the gradually internationalized small and medium sized enterprises (SMEs). They often exceed competitors in the speed of launching innovations and are flexible in entering new markets. The entrepreneurial orientation (EO) indicators are at low to medium levels in all studied SMEs. However, the propensity to risk is slightly stronger in the INVs and correlated moderately with the financial performance. As the study shows, lack of emphasis on marketing planning and information gathering is the characteristic of the Polish INVs, which may testify to their effectual approach to decision making. Furthermore, similar as in the foreign-based INVs, there may exist a relationship between the application of the EM concept and performance of the Polish INNs, which, however, requires further study with respect to some mediating factors. It has been concluded that innovativeness of the product offering and propensity to risk seems to be the characteristic EM concept elements accompanying the rapid internationalization of INVs. The future research should focus on other elements of the EM-mix applied by INVs originating from emerging economies. 展开更多

Often, the word "community" and "sustainability" are interlinked in 21st century development approaches. Most development communicators have focused on top-down communication strategies and used various means to diffuse the message to the target community. However, with the change in media landscape today, the challenge is how to select the "right" communication application to foster the behavioral and cognitive sustainable changes in their own community. This research aims to investigate theatrical performance as sustainable communicative means demonstrating environmental issues and the concepts of sustainable development among high school students and Chiang Mai University students. With the application of "Devised Theatre", the process provides a space to investigate the attributes, characteristics and development of community theatre on how it reflects the concept of communication for social change. The research, therefore, examines the outcome of this creative social application tool and utilizes Practice as Research (PAR) a research methodology. The result will reveal the following: (1) how dramatic arts can be an effective means of social marketing to raise "awareness" on environmental issues; (2) how the performance raises environmental awareness in not only physical and psychological phases, but also spiritual dimension as a learning process among the participants, and (3) the sustainability of theatrical social application tool in which the participants of devised theatre project (devisees) can become the devisors in order to form new generation of the devisees--the teenage audience. 展开更多

The global economic crisis that blew up at the end of 2006 in the United States has had extremely negative impacts on the social, political, and economic fields. The countries operating in the most affected macro areas---the United States and Europe---have put through the wringer the domestic trade relationships as well as the international ones, by injecting a chain reaction into the global economic scenario. However, there are countries that seem to be free from the economic and financial contagion overflowing over the past years, as they are moved by an "invincible projection toward the growth". The present study aims to analyze how much the main emerging market of China has been effectively involved in this vicious circle. More specifically, the study intends to propose an empirical analysis on the real connection between the macroecnnomic data and the strong structure of the Chinese publicly listed companies. This paper investigates the prediction of failure among 3,220 Chinese publicly traded companies (listed companies) during the global crisis period. By analysing the financial accounting data over the past seven years (2008 to 2014), the emerging market score (EMS) has been adopted in order to investigate the impact of the crisis on financial distress in the main emerging market of China. The results confirm the following hypotheses: On one hand, the great majority of companies have not been suffering the downturn, since 71.93% of the entire samples present no risk of financial distress during the global crisis; on the other hand, only 6.18% have a reasonable risk of financial distress. 展开更多

The reformation of the economy system has led the f un ctional department and status of the enterprises into a variable state. Under th e condition of the market economy, the kernel of the enterprises’ functional dep artment has diverted to that of marketing decision-making, which face to market and meet with the need of consumption. Assuredly, the kernel of marketing decis ion-making is to prognosticate the future market demand of the production of en terprises accurately, so that it can ensure and realize the maximum of the enter prises’ profit increase. Using empirical research and the multi-regression technique, this paper ana lyzes the enterprises’ production demand forecast of the GMC (Global Management Challenge, held every year globally) and changes most of uncontrollable factors of demand forecast to the controllable ones of the enterprises. The method we us ed to forecast demand by using the multi-regression technique is as follows: 1. Look for the main factors which influence the demand of productions; 2. Establish the regression model; 3. Using the historical data, find the resolution of the correlative index an d do the prominent test; 4. Analyze and compare, regression, adjust parameter and optimize the regress ion model. Our method will make the forecast data closer to the actual prices of the future market requirement quantity in the production marketing decision-making of the enterprises and realize the optimizing combination and the working object w ith the minimum of the cost and the maximum of the profit. And it can ensure the realization of the equity maximum of the enterprises and increase the lifecycle of the production. 展开更多
