ABSTRACTFrance Mountain is located within Overton County which is part of the Upper Cumberland region of Middle Tennessee contains only one species of scorpion, also the only species native to the state, Vaejovis carolinianus. This species is poorly researched, and little is known about its life history and ecology. The objectives of this study were to determine if female V. carolinianus prefer to form aggregations under large cover objects or seek out retreat sites where they would be the sole occupant. Based on past research, we hypothesized that females would form aggregations under large cover objects instead of being the sole occupant. A total of 32 scorpions were captured during August and September 2014. During laboratory trials, three scorpions were placed in a plywood tray containing sand substrate and three equally-sized large ceramic tiles. The scorpions were left undisturbed for a 24-hour period, after which the tiles were lifted to check for aggregations. Each group of three scorpions was in the research tray for three consecutive days. Four rounds of aggregation trials were conducted, and t-tests as well as linear regression were used to analyze the data collected. The results of the t-test showed that female V. carolinianus, when given a choice of similarly-sized large cover objects, would select a retreat site where they were the sole occupant; therefore, our initial hypothesis was rejected. Linear regression found relative humidity affected aggregation occurrence, for the largest number of aggregations occurred when the relative humidity was between 67 and 73%.

ANALISIS VARIABEL YANG BERPENGARUH TERHADAP KINERJA PERUSAHAAN DI BURSA EFEK INDONESIAOleh : Suseno STIE SATRIA Purwokerto ABSTRACT The aims of the research are (1) to analyze influence of age, scale, financial leverage, and profitability to performance of firms at The Indonesian Stock Exchange. (2) to determine the most influential variable on the performance of the firms. Hypotheses proposed in this research were: (1) Age, Scales, Financial Leverage, Profitability influences the performance of firms, (2) Age influences the performance of firms, (3) Scales influences the performance of firms, (4) Financial Leverage influences the performance of firms, (5) Profitability influences the performance of firms. Instrument of analysis employed in the research was multiple linear regression with t test and F test.The results of analyses of t test showed that profitability did not influence the performance of the firms. It was indicated by the value of computed t which was smaller than the value of t table. Meanwhile, the t test of age, scale and financial leverage indicated that the value of computed t &gt; t table. It means that these variables (scale and financial leverage) influenced the performance of the firms. The F test showed that the independent variables of age, scale, financial leverage and profitability as a whole significantly influenced the performance of the firms. It was indicated by the calculated F &gt; the value of F table, the value the age computed t which was smaller than the value of -t table..Based on the research results that age and profitability do not influence the performance of the firms, it is suggested that investors should not pay any attention to those variables. On the other hand, they should pay attention to the variables of scale and financial leverage. It is recommended that for further research should include longer periode of the sample.

In the article the author mentions some modern publications on this issue in the era of Alexander I and Nicholas I in connection with the description of the travelling theme in the context of everyday life history. As an example of the Russian Province, the article considers Smolensk Governorate which was located at the crossroads of routes from Europe to the center of Russia through Baltic, Belarusian and Ukrainian Provinces. On the basis of the materials of the State Archive of the Smolensk region (GASO) from the funds of the Chancellery of Smolensk Governor, the Smolensk Oblast Duma, metric books of Roman Catholic Church in Smolensk and published memoirs (Eugene Hess’ diary and E. Montulé’s notes) the author of the article reconstructs foreign hotel owners’ biographies (S.I. Chapa, D.K. Nolchini, V.I. Gaber), masters of carriage business (D.I. Graf, K.B. Weber), a city coachman, the owner of a coffee house (H. Podrut). All these people were united by their origin (they came from European countries) and their involvement (due to their professional activities) in servicing travelers who found themselves in the Russian Province. Life circumstances and development of their own business forced them to settle far away from their homeland; most of them became citizens of the empire, having connected themselves with Russia forever. In the article it is underlined that foreigners’ involvement in «tourist business» of the considered epoch testifies not only to the benefit of their business activity, but also to the importance of the psychological factor – the very possibility of meeting with compatriots and representatives of other European countries.

The halal industry is very developed lately. The halal lifestyle that is currently trending in Indonesia consists of the Islamic financial sector, halal food, halal travel, halal clothing, halal recreation, and halal media, halal medicines, halal medical care (hospital), and halal cosmetics. For example, a pharmaceutical industry such as Sidomuncul. Sidomuncul is a company that has the most halal products at this time. This study aims to partially examine the effect of the halal label and the expiration date on purchasing decisions. Then simultaneously analyze the effect of the halal label and the expiration date on Sidomuncul purchasing decisions. This research is quantitative descriptive research. The method in this research uses multiple linear regression with SPSS 25. The population in this study are all people who buy Sidomuncul products, while the sample in this study was determined by 50 respondents. The results of this study resulted in a significant t-test value of 0,000, which means partially the halal label has a significant effect on purchasing decisions, the expiration date resulted in a significant t-test value of 0,006, which means partially expiration date has a significant effect on the Sidomuncul product purchase decision, and simultaneously the halal label and expiration date affect the Sidomuncul product purchase decision.

Great Circle Distance

In this study, 98 regression models were specified for easily estimating shortest distances based on great circle distances along the U.S. interstate highways nationwide and for each of the continental 48 states. This allows transportation professionals to quickly generate distance, or even distance matrix, without expending significant efforts on complicated shortest path calculations. For simple usage by all professionals, all models are present in the simple linear regression form. Only one explanatory variable, the great circle distance, is considered to calculate the route distance. For each geographic scope (i.e., the national or one of the states), two different models were considered, with and without the intercept. Based on the adjusted R-squared, it was observed that models without intercepts generally have better fitness. All these models generally have good fitness with the linear regression relationship between the great circle distance and route distance. At the state level, significant variations in the slope coefficients between the state-level models were also observed. Furthermore, a preliminary analysis of the effect of highway density on this variation was conducted.

Education In China

Based on the fairness and benefits of the opportunity to accept higher education, tuition should be paid. The average cost of higher education and the ability to pay tuition which is determined by the average income are two fundamental basics for making the standard of tuition. In order to research the standard of tuition, the paper has focused on two issues: What is the acceptable range of tuition for higher education in China? How much is the reasonable tuition for higher education in China? Then we have established a multiple linear regression model on the basis of the reasonable assumption. Using the Eviews Software, we got that the range of average tuition was [4674.4, 7516.1]. Then we made a sensitivity analysis on the state funding and got the conclusion, tuition of colleges and universities all over our country were reasonable, and that the average tuition was negatively correlated to the state funding to some extent. Through the conclusion, we obtained that the state funding accounted for 25% in training costs of students. When the state funding rose by 250 yuan, the average tuition would decrease by 238 yuan.
