The Effect of Range Site and Range Condition on the Growth and Development of Western Wheatgrass

One of the problems confronting the range administrator or ranch manager in making sound grazing management decisions is lack of detailed knowledge about the growth and development of herbage grasses. It is important to know how the desirable grass species in a particular area will respond to the time and frequency of harvesting in order to formulate a grazing management plan that will permit maximum sustained livestock production while maintaining or improving the species composition and the vigor of the important forage plants. Taller and more palatable grasses are replaced by shorter grasses as grazing intensity is increased; thus, foliage production per acre is reduced. Knowledge of the patterns of growth and development of the key management species at various times throughout the growing season is important in the preparation of a grazing management plan. The objectives of the study conducted at the Cottonwood Range Field Station and reported herein were to determine (1) the effect of range site and range condition on: time of shoot emergence, shoot length and leaf number, rate of length increase and leaf development, proportions of shoots producing seedstalks, shoot and leaf condition at various observation dates, height and location of the apical meristem, and total available carbohydrate (TAC) concentration in rhizomes of western wheatgrass; and (2) to determine the effect of emergence date within each site or range condition, and seedstalk production

Analysing Political Biases in Danish Newspapers Using Sentiment Analysis

Traditionally, the evaluation of political biases in Danish newspapers has been carried out throughhighly subjective methods. The conventional approach has been surveys asking samples of thepopulation to place various newspapers on the political spectrum, coupled with analysing votinghabits of the newspapers’ readers (Hjarvard, 2007). This paper seeks to examine whether it ispossible to use sentiment analysis to objectively assess political biases in Danish newspapers. Byusing the sentiment dictionary AFINN (Nielsen et al., 2011), the mean sentiment scores for 360articles was calculated. The articles were published in the Danish newspapers Berlingske andInformation and were all regarding the political parties Alternativet and Liberal Alliance. Asignificant interaction effect between the parties and newspapers was discovered. This effect wasmainly driven by Information’s coverage of the two parties. Moreover, Berlingske was found topublish a disproportionately greater number of articles concerning Liberal Alliance thanAlternativet. Based on these findings, an integration of sentiment analysis into the evaluation ofbiases in news outlets is proposed. Furthermore, future studies are suggested to construct datasetsfor evaluation of AFINN on news and to utilize web-mining methods to gather greater amounts ofdata in order to analyse more parties and newspapers
