A model for understanding new media literacy : epistemological beliefs and social media use

AbstractNew media literacy (NML) skills are regarded as crucial for the 21st century. However, there is limited research on the factors affecting NML skills. A robust model was built for exploring the antecedents of NML. The model incorporated epistemological beliefs and social media use purposes. Individuals’ purposes of social media use were found to have an effect on beliefs about information. Further, interactional and communicational use of social media makes epistemological beliefs more sophisticated. However, it is more likely to have naïve beliefs with the use of social media for making new friends. Also, the purposes of social media use and epistemological beliefs affect NML skills. Accordingly, interactional use of social media might contribute to justifying information, in turn, increasing NML skills. This study indicates that knowledge of social media use and epistemological beliefs enables us to largely understand the NML skills.Abstract New media literacy (NML) skills are regarded as crucial for the 21st century.

PECKING ORDER AND TRADE-OFF THEORIES IN FORMING CAPITAL STRUCTURE: AN IMPLEMENTATION IN TEXTILE INDUSTRY IN THE WEST MEDITERRANEAN REGION OF TURKEY

Increasing competitive environment’s pressure on business organizations during globalization process and after it prompts finance managers to be more cautious about business financing and establishing capital structure. Capital structure decisions change capital components of business organizations and thus become more important in terms of decreasing capital cost and increasing firm value. Modigliani’s and Miller’s approach towards capital structure are the most outstanding ones among the studies related to this issue. It seems that this approach was adopted intensely first and developed by other studies which were done later; even from its drawbacks new capital structure approaches have been suggested. Since bankruptcy and agency cost, arising from excessive borrowing, and asymmetric information problem affect capital cost and firm value, they should be taken into account at least as much as tax advantage provided by the loan for establishing capital structure. In this paper, we tried to form a frame for capital structure at first and then mentioned about trade-off and pecking order theories on establishing capital structure. In the next stage, we referred to previous studies in literature concerning approaches adopted for establishing business organisations’ capital structures. In the last part, a field research, relating to the importance of factors which are taken into account while establishing capital structure in textile businesses, was applied, and analyses regarding the determination of current situation of active business organizations were done. We also applied face-to-face survey method in this study, and the analysis was carried out by subjecting hypotheses to t-test and chi square test with the help of SPSS packaged software

Teachers’ skills to integrate technology in education : Two path models explaining instructional and application software use

AbstractThe purpose of this study was to examine the effect of technology support, teachers’ confidence in using technology, their beliefs about using technology, and their perceived skills on the use of instructional and application software. The data we used were from 1335 K-12 teachers involved in the Technology Uses and Perceptions Survey (TUPS) study. Teachers were located in 40 different institutions across the state of Florida. According to the findings of this study, the most significant factor in the instructional and application software use of teachers was found as perceived technology skills. Therefore, professional development for perceived skills or technology competencies of teachers might contribute to increasing the instructional or application software use of teachers. In terms of confidence and comfort using technology, they both had direct and positive effects on instructional and application software. Also, the total effect of support from technology specialists for instructional software use is more than application software use. As evidenced by the models developed in this research, teachers’ perceived technology skills for instructional and application software use directly and positively affected their beliefs on usefulness. Our effort to provide more emphasis on the combined effect of a collective set of factors to explain teacher use of technology leads us to address the gaps in the literature on technology use (i.e., the effect of demographic factors and technology availability).Abstract The purpose of this study was to examine the effect of technology support, teachers’ confidence in using technology, their beliefs about using technology, and their perceived skills on the use of instructional and application software.

The Promises and Challenges of Artificial Intelligence for Teachers : a Systematic Review of Research

AbstractThis study provides an overview of research on teachers’ use of artificial intelligence (AI) applications and machine learning methods to analyze teachers’ data. Our analysis showed that AI offers teachers several opportunities for improved planning (e.g., by defining students’ needs and familiarizing teachers with such needs), implementation (e.g., through immediate feedback and teacher intervention), and assessment (e.g., through automated essay scoring) of their teaching. We also found that teachers have various roles in the development of AI technology. These roles include acting as models for training AI algorithms and participating in AI development by checking the accuracy of AI automated assessment systems. Our findings further underlined several challenges in AI implementation in teaching practice, which provide guidelines for developing the field.Abstract This study provides an overview of research on teachers’ use of artificial intelligence (AI) applications and machine learning methods to analyze teachers’ data.

A Theoretical Approach for Determining Irregularities of the Bottom of the Tillage Layer Caused by Horizontal Axis Rotary Tillers

Horizontal axis rotary tillers produce irregularities in the tillage depth when they are inappropriately operated and constructed. In such cases, mixing and breaking of soil throughout the tillage layer is not uniform and some untilled ridges will remain at the bottom determining the effect of design and operational characteristics on the height of the resultant ridges at the bottom of the tillage layer. In this study, a method based on the derived geometrical relationships between the rotary tiller operational parameters was developed to determine heights of ridges occurring at the bottom of the tillage layer. The ridge heights can be calculated for various combinations of blade peripheral speed, forward travel speed, rotor radius, and the number of blades on one side of a rotary tiller flange. This method allows for the investigation of effects of rotary tiller operational and constructional properties of horizontal axis rotary tillers on the ridge heights at the bottom of the tillage layers. The results obtained using this method show that the heights of ridges at the bottom of the tillage layer increase with increases in forward travel speed and decrease with increases in blade peripheral speed, rotor radius, and the number of blades on one side of a flange

One-Stage Combined Thoracic Ancient Schwannomas Total Removal and Coronary Artery Bypass

Ancient schwannoma is a rare variant of neural tumors though rarely seen in the thorax. The combination with coronary artery diseases is also rare. Here we describe a 66 year-old male who had undergone one-stage combined surgery for thoracic ancient schwannomas removal and coronary artery disease. The masses were, respectively, 13 cm in the middle mediastinum and 5 cm in diameter originating from the intercostal nerve. The tumors were successfully removed using sternotomy, and then a coronary artery bypass grafting was performed. Here we discuss this rare tumor in relation to the relevant literature

A Reduced Order Model for the Design of Oxy-Coal Combustion Systems

Oxy-coal combustion is one of the more promising technologies currently under development for addressing the issues associated with greenhouse gas emissions from coal-fired power plants. Oxy-coal combustion involves combusting the coal fuel in mixtures of pure oxygen and recycled flue gas (RFG) consisting of mainly carbon dioxide (CO2). As a consequence, many researchers and power plant designers have turned to CFD simulations for the study and design of new oxy-coal combustion power plants, as well as refitting existing air-coal combustion facilities to oxy-coal combustion operations. While CFD is a powerful tool that can provide a vast amount of information, the simulations themselves can be quite expensive in terms of computational resources and time investment. As a remedy, a reduced order model (ROM) for oxy-coal combustion has been developed to supplement the CFD simulations. With this model, it is possible to quickly estimate the average outlet temperature of combustion flue gases given a known set of mass flow rates of fuel and oxidant entering the power plant boiler as well as determine the required reactor inlet mass flow rates for a desired outlet temperature. Several cases have been examined with this model. The results compare quite favorably to full CFD simulation results
