The Role of Entrepreneurial Climate in Rural Tourism Development : A Factorial Analysis

Masoud Ghorban Hosseini 세계문화관광학회 2011 Conference Proceedings Vol.12 No.-

Tourism development has been embraced in the last decade as an economic development tool for rural areas. A parallel movement has recently swelled emphasizing entrepreneurship as a viable strategy for economic sustenance. This study combines the two areas and in particular examines the entrepreneurial climate of a community and its contribution to tourism Development. Schimla City in Himachal Pradesh State was the research area. It is a deprived and Beautiful state which is settled in North West of India. The research design was a descriptive and correlation surveying method. Exploratory factor analysis was used to reveal seven subscales of entrepreneurial climate (e-climate). The seven subscales were labeled Community Culture Training & Assistance Institutional Support Quality of Life Amenities Business Services Economic Development-Infrastructure Support and Natural Resources-Tourism Business Support. These e-climate subscales along with additional county-based descriptors were included as independent variables in a multiple regression analysis to determine their importance in explaining the dependent variable Tourism Expenditures. County-based descriptors included the economic health of a county (Economic Tier) the population and remoteness of the county (Rural-Urban Continuum Code) the level of tourism support in the county (Tourism Support) and the potential for tourism development (Tourism Opportunity). This study contributes to the measurement of entrepreneurial climate as well as to the understanding of its impact on tourism development. Implications for management and policy are also suggested.

The Role of Uniconazole in Improving Physiological and Biochemical Attributes of Bean (Phaseolus vulgaris L.) Subjected to Drought Stress

Keshavarz, Hamed,Ghorban Khodabin 한국작물학회 2019 Journal of crop science and biotechnology Vol.22 No.2

Adverse environmental conditions such as drought are among the major factors limiting the growth and productivity of land plants. Plant growth regulators are defined as naturally occurring or synthetic compounds that affect the development or metabolism of higher plants, mostly in abiotic stress conditions. Two varieties of common bean, Talash (Sensitive) and Dehghan (Tolerant) were used to examine the influences of uniconazole on the photosynthetic traits, antioxidant activities, and morphological parameters of bean leaves and root under drought stress conditions. Results showed that drought stress considerably depressed the plant growth. However, the drought-stressed plants treated with uniconazole showed significantly higher biomass than in plants without uniconazole. Uniconazole treatments on Dehghan showed superior results to those on Talash. The leaves of uniconazole plants exhibited an increased leaf greenness content, photosynthetic rate, transpiration rate, and stomatal conductance but lower lipid peroxidation content and relative electrical conductivity compared to those of drought-stressed plants. Soluble sugar, soluble protein content, and the activities of superoxide dismutase, peroxidase, and catalase in the leaves were increased by uniconazole in drought stress and under well-watered conditions. Finally, the findings indicated that uniconazole can effectively alleviate the adverse effects caused by drought stress; these unwanted changes are partially attributable to the modifications in morphology and physiological characteristics resulting in yield increase in drought bean.

Bahman Ramavandi,Ghorban Asgari,Javad Faradmal,Soleyman Sahebi,Babak Roshani 한국화학공학회 2014 Korean Journal of Chemical Engineering Vol.31 No.12

Taguchi orthogonal design was applied for multivariate optimization of Cr (VI) abatement by canta-loupe peel powder (CPP), as a novel adsorbent, from industrial wastewater in a batch mode. Effective factors in theadsorption process, such as temperature, CPP dose, Cr (VI) concentration, wastewater pH, and contact time, were con-sidered using an L16 orthogonal array design. The best conditions for adsorbing of Cr (VI) were determined by the Taguchimethod and desirability approach as pH of 2, chromium concentration of 100 mg/L, contact time of 5 min, CPP dosageof 0.5 g/L, and wastewater temperature of 25 oC. Analysis of variance results indicated that the pH was the most im-portant variable influencing the chromium removal percentage, and its contribution value was obtained 45.01%. TheLangmuir model proved best fit for the experimental data and maximum adsorption capacity of Cr (VI) onto CPP wasobtained 166.25 mg/g. The final part of the study includes an examination of the CPP through an analysis of the removalof chromium from real industrial wastewater. It can be concluded that the CPP presents a promising and efficient al-ternative for eliminating of Cr (VI) from industrial wastewaters.

Purpose: In order to keep the acceptable level of the radiation oncology linear accelerators, it is necessary to apply a reliable quality assurance (QA) program. Materials and Methods: The QA protocols, published by authoritative organizations, such as the American Association of Physicists in Medicine (AAPM), determine the quality control (QC) tests which should be performed on the medical linear accelerators and the threshold levels for each test. The purpose of this study is to increase the accuracy and precision of the selected QC tests in order to increase the quality of treatment and also increase the speed of the tests to convince the crowded centers to start a reliable QA program. A new method has been developed for two of the QC tests; optical distance indicator (ODI) QC test as a daily test and gantry angle QC test as a monthly test. This method uses an image processing approach utilizing the snapshots taken by the CCD camera to measure the source to surface distance (SSD) and gantry angle. Results: The new method of ODI QC test has an accuracy of 99.95% with a standard deviation of 0.061 cm and the new method for gantry angle QC has a precision of $0.43^{\circ}$. The automated proposed method which is used for both ODI and gantry angle QC tests, contains highly accurate and precise results which are objective and the human-caused errors have no effect on the results. Conclusion: The results show that they are in the acceptable range for both of the QC tests, according to AAPM task group 142.

Banafsheh Beheshti Monfared,Ghorban Noormohamadi,Amir Hossein Shirani Rad,Eslam Majidi Hervan 한국작물학회 2020 Journal of crop science and biotechnology Vol.23 No.1

Changes in the environment that are associated with different sowing dates can be expected to alter canola (Brassica napus L.) growth and development. The objective of this work was to study the effect of sowing date and chitosan on some characters of canola genotypes. Five genotypes (RGS003, Sarigol, Zafar, Dalgan, and Julius) were sown in three sowing dates (October 7, 17, and 27), for two years (2014-2015 and 2015-2016). A factorial split-plot experiment was conducted in a complete randomized blocks design with three replications, where the sowing dates and the two levels of chitosan (0 [control] and 0.2% concentrations) were allotted to main plots and the genotypes were allotted to subplots. The ANOVA revealed that the main effects of sowing date, chitosan and genotype were significant for almost all measured characters. In addition, the interaction effect of sowing date and genotype was significant for plant height, number of silique in shoots, number of seeds per main silique, 1000-seed weight and oil yield. The seed and oil yields in the third sowing date were reduced by 0.46 and 0.49%, respectively, compared to the first sowing date. The results of the present study indicated that early sowing date and chitosan application had positive effects on the measured characters. Cluster analysis divided the cultivars into two groups. Also, the PCA revealed that the three first PC confirmed about 98% of the total variance among the studied genotypes.

WHEN SHAKESPEARE TRAVELS ALONG THE SILK ROAD: TARDID, AN IRANIAN ADAPTATION OF HAMLET

GHANDEHARION, AZRA,JAGHRAGH, BEHNAZ HEYDARI,SABBGH, MAHMOOD GHORBAN Academia Via Serica 2017 Acta Via Serica Vol.2 No.1

Media has become an inseparable companion of $21^{st}$ century culture, exerting immense influence on our daily lives. This article aims to reveal how cultural aspects and media in a particular part of the Silk Road have adapted Western cannons. Iran has redefined and transformed Western culture through the modern Silk Road by the method of cinematic adaptation. Karim-Masihi employs the general plot of Hamlet, the well-known drama by William Shakespeare (1564-1616), in his movie Tardid (Doubt 2009); however, he transforms some of the characters to reflect the current socio-cultural aspects of Iranian society. One of the characters is named Siavash, whose life is similar to Hamlet. In passivity, he awaits his imminent death and other tragic consequences. Yet, the movie ends differently. It is not an Elizabethan tragedy in a strict sense, although the final scenes abound with corpses. This article aims to find the similarities and differences between the two works, while reasoning the significance of the alterations. It concludes with how different cultures react to the same themes.
