The relationship between leadership styles and graduate academic majors /

Major conclusions which were supported by the results of this research were that there are statistically significant differences between leadership styles, style range (flexibility), and style adaptability (effectiveness) of applied science graduate students and social science graduate students. The facts that the social science graduate students achieved higher scores on style range and style adaptability, and that they were more inclined toward participating as a leadership style than were applied science graduate students, reinforce the following general conclusion: social science majors are probably more relationship-oriented than are applied science majors. This may suggest the need for applied science majors who aspire to administrative positions to become involved in appropriate training programs designed to help them perform more adequately in administrative positions.The Leader Effectiveness and Adaptability Description (LEAD-Seff) developed by Hersey and Blanchard was used to measure the leader style, style range, and style adaptability. The Demographic Information Questionnaire developed by the investigator was used for the purpose of defining and describing respondents who participated in the study.A number of null hypotheses were developed for the purpose of investigating the problem. Three statistical tests were performed: the chi-square, analysis of variance, and the Pearson correlation coefficient. Two null hypothesis could not be rejected.The purpose of the study was to investigate the relationship between leadership styles and graduate academic majors. The theoretical framework of the study was Hersey and Blanchards' Situational Leadership Theory.The populations from which the samples were drawn consisted of graduate students who were majoring in the areas of applied sciences and in the areas of social sciences, at the University of Oklahoma, during the spring semester of 1982. The 96 respondents consisted of 48 applied science graduate students (15 females; 33 males) and 48 social science graduate students (22 females; 26 males)

Rumor Stance Classification in Online Social Networks: A Survey on the State-of-the-Art, Prospects, and Future Challenges

The emergence of the Internet as a ubiquitous technology has facilitated the rapid evolution of social media as the leading virtual platform for communication, content sharing, and information dissemination. In spite of revolutionizing the way news used to be delivered to people, this technology has also brought along with itself inevitable demerits. One such drawback is the spread of rumors facilitated by social media platforms which may provoke doubt and fear upon people. Therefore, the need to debunk rumors before their wide spread has become essential all the more. Over the years, many studies have been conducted to develop effective rumor verification systems. One aspect of such studies focuses on rumor stance classification, which concerns the task of utilizing users' viewpoints about a rumorous post to better predict the veracity of a rumor. Relying on users' stances in rumor verification task has gained great importance, for it has shown significant improvements in the model performances. In this paper, we conduct a comprehensive literature review on rumor stance classification in complex social networks. In particular, we present a thorough description of the approaches and mark the top performances. Moreover, we introduce multiple datasets available for this purpose and highlight their limitations. Finally, some challenges and future directions are discussed to stimulate further relevant research efforts.Comment: 13 pages, 2 figures, journa

Ground Improvement of Dhu Al-Kifil Minaret Using Micropile and Cement Grouting

The Minaret of Dhu Al-Kifil Nabi (PBUH), located in the city of Kifil with a height of about 25 meters, is one of the historical monuments of Iraq. The 4.5 degree deviation of this Minaret has become a challenge for authorities in recent years. Various reasons, such as the old age of the building and manipulation of the soil of the minaret bed, damage the structure and have caused it to deviate from the vertical direction and form cracks at its height. A temporary metal retaining structure is currently constructed on the site to maintain the building in its current state. Still, in order to remove it and repair the body and foundation of the Minaret, the designs have been carried out by Iranian engineering groups. After that, its strengthening operations have also finished. In this article, after the introduction of the project, the analytical and numerical results of the bed improvement plan using the combination of inclined and vertical micropiles are presented. Finally, the reliability of the plan in controlling the heterogeneous settlement of the Minaret is assessed

Factors Related to Patient Migration from Kerman Province to Yazd for Receiving Inpatient Services

Background: Migration of patients from Kerman province to Yazd city is an old issue that despite Kerman’s health care system improvements is still continuing. The elimination or decrease of probable problems of the health care system and consequently decreasing patients' motivation for receiving health services in other provinces requires studies about the factors related to these migrations. Methods: This was a cross-sectional descriptive and applied study. Data were gathered in January and May 2015 from two private and one public hospital of Yazd. In the quantitative part of the research, using international classification of diseases codes, disease groups with the highest patients' migrations were found; and using Spearman test, the relation between geographical distance and patient migration was investigated. Then, in the qualitative part of the research, migration reasons were asked through phone call interviews. Results: Most migrations occurred in groups of neoplastic, circulatory and digestive diseases. Geographical distance and the number of migrants of each county showed a relatively strong negative significant relation. Migration reasons were classified in 3 main themes including Yazd health care characteristics, Kerman health care characteristics and characteristics of the patients. Conclusion: In order to prevent patients’ migration for the purpose of receiving services that are available in their own province or at least in the province capital, the quality of services should be addressed. Paying attention to health services costs and welfare facilities for patient attendants is important in reducing unjustified migrations

Excavation Support and Foundation Ground Improvement Using Jet Grouting Method – A Case Study

One of the soil improvement methods is using soil-cement columns, and one of the most common methods of implementing these columns is the Jet grouting method. In this article, the performance of Jet grouting columns in soil improvement and excavation wall stabilization is investigated in a project located in Chalous, north of Iran, by implementing several experimental soil-cement columns in real scale at depths of 4, 8, and 15 meters and diameter of 80 cm. By comparing the soil settlement before and after the improvement, it was found that the average settlement, which was in the range of 186 mm before the improvement, reached about 68 mm after the improvement using the jet grouting method. It has been observed that the settlement of the foundation has been significantly reduced after improving the ground with soil-cement columns. On the other hand, the results of this study showed that this method has also been very effective in stabilizing the excavation walls. The maximum displacement of the crest of the wall is about 3.4 cm, and the maximum settlement behind the wall is limited to 12 mm

Factors Affecting Health Care Utilization in Tehran

Introduction: Successful health system planning and management is dependent on well informed decisions, so having complete knowledge about medical services’ utilization is essential for resource allocation and health plans. The main goal of this study is identification of factors effecting inpatient and outpatient services utilization in public and private sectors. Methods: This study encompasses all regions of Tehran in 2011 and uses Urban HEART questionnaires. This population-based survey included 34700 households with 118000 individuals in Tehran. For determining the most important factors affected on health services consumption, logit model was applied. Results: Regarding to the finding, the most important factors affected on utilization were age, income level and deciles, job status, household dimension and insurance coverage. The main point was the negative relationship between health care utilization and education but it had a positive relationship with private health care utilization. Moreover suffering from chronic disease was the most important variable in health care utilization. Conclusions: According to the mentioned results and the fact that access has effect on health services utilization, policy makers should try to eliminate financial access barriers of households and individuals. This may be done with identification of households with more than 65 or smaller than 5 years old, people in low income deciles or with chronic illness. According to age effect on health services usage and aging population of Iran, results of this study show more importance of attention to aged population needs in future years

Polyurethane composite adsorbent using solid phase extraction method for preconcentration of metal ion from aqueous solution

Polyurethane composite adsorbent polymeric material was prepared and investigated for selected solid-phase extraction for metal ions, prior to its determination by inductively coupled plasma optical emission spectrometry. The surface characterisation was done using Fourier transform infrared spectroscopy. The separation and preconcentration conditions of the analytes investigated includes influence of pH, sample loading flow rate, elution flow rate, type and concentration of eluents. The optimum pH for the highest efficient recoveries for all metal ions, which ranged from 70 to 85 %, is pH 7. The metal ions were quantitatively eluted with 5 mL of 2 mol/L HNO3. Common coexisting ions did not interfere with the separation. The percentage recovery of the metal ions ranged between 70 and 89 %, while the results for the limit of detection and limit of quantification ranged from 0.249 to 0.256 and 0.831 to 0.855, respectively. The experimental tests showed good preconcentration results of trace levels of metal ions using synthesised polyurethane polymer adsorbent composite

The Comparison of Quality of Life among Hem Dialysis and Peritoneal Dialysis Patients in Kerman

Abstract Introduction: When severe kidney failure happens and kidneys do not work properly, alternative treatments such as transplantation and dialysis, including hemodialysis and peritoneal dialysis can be done. This study is to help physicians and patients in choosing an appropriate therapeutic method in terms of the impact on quality of life comparing different dimensions of hemodialysis and peritoneal dialysispatients'quality of life. Method: In this cross-sectional descriptive analytical study, 143 patients with hem dialysis and peritoneal dialysis have been studied in a hospital in Kerman at the second six months of 2011. In order to survey thepatients' quality of life and comparing it from various dimensions, the EQ5D quality of life questionnaire was used. Data analysis was done by SPSS software version 19, and also using descriptive statistics such as frequency tables, mean, and standard deviation statistics, chi-square and Mann-Whitney analysis. Results: The average scores for quality of life in patients with hem dialysis and peritoneal dialysis were 0.61 vs. 0.69, respectively and the difference was meaningful. The highest average score in the hemodialysis patients quality of life was related to depression and anxiety (0.95) and in peritoneal dialysis patients was related to personal care (0.96). In this study, there were not any statistically significant relationships between any of the studied variables and the quality of life except age variable in two groups of patients. Conclusion: This study revealed that peritoneal dialysis patients had higher quality of life particularly in the personal care and pain and had better life quality compared to hemodialysis patients.
