AbstractIntroduction:This paper presents the results of a survey on excellent teachers conducted in Hungary in 2018. The main question of the study was how pedagogical talents can be characterised by competences and personality traits according to effective teachers and their colleagues. Furthermore, what effective teachers think about their own competences and characteristics, as well as how that is related to their beliefs of pedagogical talents was tested.Methods:The online questionnaire method was applied in the research. The sample involved effective teachers (N=92) of high-risk students (N=25) and of gifted students (N=43), as well as supervisor teachers (N=24) who were selected by judgment sampling. The control group of teachers (N=76) had similar characteristics to the sample as they were matched by the type of institution and geographical location. The data was processed using SPSS software.Results:The excellent teachers’ beliefs about pedagogical talents showed differences in many ways. Excellent teachers of high-risk students had the most child-centred view. Not only did they pay attention to students’ needs while planning and organizing lessons, but they also found the students’ feedback important, much more than other subsamples. They also said in high proportion they can handle the challenges related to the societal level of their work. Among all the sub-samples, they indicated most frequently that excellent teachers should be happy, initiative and practical. Supervisor teachers unanimously indicated that good teachers should be highly cooperative and also that excellent teachers should be friendly and flexible. It turned out from the research that excellent teachers of gifted children used significantly fewer teaching methods than the other group. Among all sub-samples, they were the ones who found the competences of “developing student groups and communities” the least important. The data showed that the teachers in this sub-group felt less able to adapt to the changes related to the societal level of their work. The words “theoretical”, “isolated”, “serious”, „distant” appeared in a significantly higher proportion among these teachers when speaking about pedagogic talents in general. These words were frequently used when spoking about their own characteristics.Discussion:The results of the excellent teachers of high-risk students and supervisor teachers showed similarity in many regards. Both groups seemed to be methodologically well-prepared, and able to give varied enjoyable lessons, as well as to develop student communities; and to carry out continuous reflective practice. Excellent teachers of gifted students focused on academic knowledge much more than other sub-groups. They also planned and managed their lessons differently. The background of this phenomena could be that their students’ knowledge and motivation is more homogenous.Limitations:Although the size of the sample was not representative, the study confirmed and complemented former relevant research.Conclusion:The results showed that pedagogical talents can have multiple manifestations., which can be caused by the wide range of pedagogical work and the related roles. On the other hand, there are different teachers’ characteristics and competences. The study also showed that teachers’ views about excellent teachers are closely connected to the particularities of the taught student group. The researchers hope that these results can be an inspiration for further studies in this field.

A video-based method of instruction was introduced to develop students academically as well as to implement parallel medium instruction. An action research approach was followed Lectures were video-taped beforehand and worked through with the students by a tutor in scheduled Afrikaans or English periods. Simultaneously a live class situation was handled by the lecturer in the other language. Over and above these methods additional video-based support sessions were conducted by tutors for high risk students. A survey indicated that 85% of students were satisfied with this method of instruction. The perceptions of high risk students to VSI were positive and they passed the examinations. Video lectures need to be carefully planned in order to be acceptable as one of a number of possible instruction methods at a multi-cultural university.

Ultrasonic Thickness

Ultrasonic thickness gauges are easy to operate and reliable, and can be used to measure a wide range of thicknesses and inspect all engineering materials. Supplementing the simple ultrasonic thickness gauges that present results in either a digital readout or as an A-scan with systems that enable correlating the measured values to their positions on the inspected surface to produce a two-dimensional (2D) thickness representation can extend their benefits and provide a cost-effective alternative to expensive advanced C-scan machines. In previous work, the authors introduced a system for the positioning and mapping of the values measured by the ultrasonic thickness gauges and flaw detectors (Tesfaye et al. 2019). The system is an alternative to the systems that use mechanical scanners, encoders, and sophisticated UT machines. It used a camera to record the probe’s movement and a projected laser grid obtained by a laser pattern generator to locate the probe on the inspected surface. In this paper, a novel system is proposed to be applied to flat surfaces, in addition to overcoming the other limitations posed due to the use of the laser projection. The proposed system uses two video cameras, one to monitor the probe’s movement on the inspected surface and the other to capture the corresponding digital readout of the thickness gauge. The acquired images of the probe’s position and thickness gauge readout are processed to plot the measured data in a 2D color-coded map. The system is meant to be simpler and more effective than the previous development.

Intrinsic And Extrinsic Motivations

The aim of the current study is to examine the intrinsic and extrinsic motivations of the gifted students from Hadhramout Gifted Center HGC in Yemen, and to investigate the impact of these intrinsic and extrinsic motivations on their giftedness development. A qualitative approach was adopted; data has been collected through an open- ended questionnaire that was prepared by the researcher and distributed among a sample of gifted students who were chosen purposively from HGC. The interpretative phenomenological method has been used to analyze the data using, Atlas ti. The results indicate that the majority of the participants consider it interesting to explore new things, and experience curiosity and desire to achieve their goals as their intrinsic motivations. Whereas, the minority consider preference to serve the community, competition preference and self-confidence as their intrinsic motivations. On the other hand, half of the participants consider rewards as their extrinsic motivation, whereas 40 % of them consider exams scores, verbal praise, parents and environment as their extrinsic motivations. Regarding the impact of intrinsic and extrinsic motivations on the development of giftedness, the majority of the participants believe that intrinsic and extrinsic motivations affect positively the development of their giftedness development. Finally, based on the findings, some recommendations were provided.

: Metal-free organocatalysts are becoming an important tool for the sustainable developments of various bioactive heterocycles. On the other hand, during last two decades, calix[n]arenes have been gaining considerable attention due to their wide range of applicability in the field of supramolecular chemistry. Recently, sulfonic acid functionalized calix[n] arenes are being employed as an efficient alternative catalyst for the synthesis of various bioactive scaffolds. In this review we have summarized the catalytic efficiency of p-sulfonic acid calix[n]arenes for the synthesis of diverse biologically promising scaffolds under various reaction conditions. There is no such review available in the literature showing the catalytic applicability of p-sulfonic acid calix[n]arenes. Therefore, we strongly believe that this review will surely attract those researchers who are interested about this fascinating organocatalyst.

Dramatic changes in recent years in the audit market suggest the timeliness of an investigation of trends in auditor concentration and an extension of prior research (e.g., Danos and Eichenseher 1982). In recent press, large audit firms have claimed that specialization is a goal of increasing importance. Peat Marwick, for example, has restructured along industry lines, claiming to be recruiting professionals for national teams of multidisciplinary experts organized to “focus on the same industry to serve clients optimally.” On the other hand, litigation concerns might prompt auditors to diversify their risks by diversifying their clientele. In this study, we examine trends in industry specialization from 1976 to 1993 and the industry factors which may affect specialization; whether market share increases are greater for audit firms classified as specialists; and whether the nation's largest audit firms have increased their market share in the industries which they have identified as their focus industries. We find evidence that concentration levels have increased over this period, consistent with the claims of the large audit firms. We find that auditor concentration levels are higher in regulated industries, in more concentrated industries and in industries experiencing rapid growth, but lower in industries with a high risk of litigation. Levels of concentration have increased over time in nonregulated industries providing evidence that scale economies or superior efficiencies of heavy-involvement auditors are not limited to regulated industries but extend to nonregulated industries as well. We also find that for the audit firms classified as market leaders at the beginning of the year, market share has increased over time, whereas market share has declined for firms with a smaller share at the beginning of the year. This suggests that there are returns to investing in specialization.

Critical Issues

Smoldering multiple myeloma (SMM), an asymptomatic plasma cell neoplasm, is currently diagnosed according to the updated IMWG criteria, which reflect an intermediate tumor mass between monoclonal gammopathy of undetermined significance (MGUS) and active MM. However, SMM is a heterogeneous entity and individual case may go from an “MGUS-like” behavior to “early MM” with rapid transformation into symptomatic disease. This wide range of clinical outcomes poses challenges for prognostication and management of individual patients. However, initial studies showed a benefit in terms of progression or even survival for early treatment of high-risk SMM patients. While outside of clinical trials the conventional approach to SMM generally remains that of close observation, these studies raised the question of whether early treatment should be offered in high-risk patients, prompting evaluation of several different therapeutic approaches with different goals. While delay of progression to MM with a non-toxic treatment is clearly achievable by early treatment, a convincing survival benefit still needs to be proven by independent studies. Furthermore, if SMM is to be considered less biologically complex than MM, early treatment may offer the chance of cure that is currently not within reach of any active MM treatment. In this paper, we present updated results of completed or ongoing clinical trials in SMM treatment, highlighting areas of uncertainty and critical issues that will need to be addressed in the near future before the “watch and wait” paradigm in SMM is abandoned in favor of early treatment.

Tensor Data

Dense subregion (subgraph & subtensor) detection is a well-studied area, with a wide range of applications, and numerous efficient approaches and algorithms have been proposed. Approximation approaches are commonly used for detecting dense subregions due to the complexity of the exact methods. Existing algorithms are generally efficient for dense subtensor and subgraph detection, and can perform well in many applications. However, most of the existing works utilize the state-or-the-art greedy 2-approximation algorithm to capably provide solutions with a loose theoretical density guarantee. The main drawback of most of these algorithms is that they can estimate only one subtensor, or subgraph, at a time, with a low guarantee on its density. While some methods can, on the other hand, estimate multiple subtensors, they can give a guarantee on the density with respect to the input tensor for the first estimated subsensor only. We address these drawbacks by providing both theoretical and practical solution for estimating multiple dense subtensors in tensor data and giving a higher lower bound of the density. In particular, we guarantee and prove a higher bound of the lower-bound density of the estimated subgraph and subtensors. We also propose a novel approach to show that there are multiple dense subtensors with a guarantee on its density that is greater than the lower bound used in the state-of-the-art algorithms. We evaluate our approach with extensive experiments on several real-world datasets, which demonstrates its efficiency and feasibility.

This paper proposes an object classification method using a flexion glove and machine learning. The classification is performed based on the information obtained from a single grasp on a target object. The flexion glove is developed with five flex sensors mounted on five finger sleeves, and is used for measuring the flexion of individual fingers while grasping an object. Flexion signals are divided into three phases, and they are the phases of picking, holding and releasing, respectively. Grasping features are extracted from the phase of holding for training the support vector machine. Two sets of objects are prepared for the classification test. One is printed-object set and the other is daily-life object set. The printed-object set is for investigating the patterns of grasping with specified shape and size, while the daily-life object set includes nine objects randomly chosen from daily life for demonstrating that the proposed method can be used to identify a wide range of objects. According to the results, the accuracy of the classifications are achieved 95.56% and 88.89% for the sets of printed objects and daily-life objects, respectively. A flexion glove which can perform object classification is successfully developed in this work and is aimed at potential grasp-to-see applications, such as visual impairment aid and recognition in dark space.

Reduce Emissions

Traffic and transportation are main contributors to the global CO2 emissions and resulting climate change. Especially in urban areas, traffic flow is not optimal and thus offers possibilities to reduce emissions. The concept of a Green Wave, i.e., the coordinated switching of traffic lights in order to favor a single direction and reduce congestion, is often discussed as a simple mechanism to avoid breaking and accelerating, thereby reducing fuel consumption. On the other hand, making car use more attractive might also increase emissions. In this study, we use an agent-based model to investigate the benefit of a Green Wave in order to find out whether it can outweigh the effects of increased car use. We find that although the Green Wave has the potential to reduce emissions, there is also a high risk of heaving a net increase in emissions, depending on the specifics of the traffic system.
