Wheat is the most imperative crop for man feeding and is planted in numerous countries under rainfed conditions in semiarid zones. It is necessary for decision-makers and governments to predict the yield of rainfed wheat before harvest and to determine the effect of the major factors on it. Different methods have been suggested for forecasting yield with various levels of accuracy. One of these approaches is the statistical regression model, which is simple and applicable for regions with scarce data available. (...) Since the weather is the most important factor affecting the production of wheat, particularly in rainfed cultivation, regression models using weather parameters are very common. However, the coefficients of these models are location based and should be determined locally. Therefore, in this research, backward multiple linear regression technique based on relative importance metrics was used to determine the most important effective weather parameters on rainfed wheat productions in Fars Province, south of Iran, during 2006–2013. The influence of each parameter in the final model was analyzed using the values of LMG relative importance metric. The result indicated that sunshine hours had the biggest LMG and, therefore, was the most effective parameter. Also, among the other considered parameters, rainy days, minimum relative humidity, and average relative humidity with LMG values of 21.97%, 21.69%, and 21.62%, respectively, had the most effects on rainfed wheat yield in the studied area. All parameters except for the sunshine hours positively affected rainfed wheat yield. The most important reason for the significance of these parameters can be the prevailing dry and semidry climate in the southern areas of Iran. The proposed model for determination of weather parameters effects on rainfed wheat could be a great guidance and aid for different stakeholders such as farmers, decision-makers, and governments.

This study investigates ethical decision-making by considering the differences in ethical judgments between undergraduate business and MBA students on selected ethical issues facing employees and managers of today's businesses. The study further investigates differences in ethical judgments between undergraduates and MBAs in terms of a perceived position as an employee or as a manager. The findings indicate that undergraduate students tend to be more ethical than MBA students and that both groups tend to be more ethical when they perceive themselves (...) as managers rather than employees. The authors discuss the implications for both business practitioners and educators. (shrink)

Background When nurses face ethical challenges, they attempt to accept responsibility for their actions and start moral reckoning. Moral reckoning is the personal evaluation of one’s behaviors or others’ behaviors during ethically challenging situations. Research Aim This study aimed at exploring the concept of moral reckoning and its stages among Iranian nurses using Nathaniel’s moral reckoning Theory. Research Design This descriptive qualitative study was conducted in 2022 using directed content analysis. Participants and Research context Eighteen nurses were purposively recruited from (...) three teaching hospitals affiliated to Golestan University of Medical Sciences, Gorgan, Iran. Data were collected via in-depth semi-structured interviews which lasted 50 minutes on average and were concurrently analyzed via the three-step directed content analysis method proposed by Elo and Kyngas. Ethical considerations This study earned the ethical approval of the Ethics Committee of Golestan University of Medical Sciences, Gorgan, Iran (code: IR.GOUMS.REC.1400.171). Findings During data analysis, 157 final codes were developed and categorized into 23 subcategories, 10 categories, and four themes. The themes of the study are ease (with the two categories of becoming and interacting), upset (with the two categories of mental upset and behavioral upset), resolution (with the two categories of making a stand and giving up), and reflection (with the four categories of remembering, telling the story, examining conflicts, and living with consequences). Conclusion Ethically challenging situations alter the ease stage of moral reckoning among nurses, cause them mental and behavioral upset, and thereby, require them to make stand or give up. Then, they continuously examine events in their mind and finally, live with the positive and negative consequences of the events. (shrink)
