Following principles derived from self-regulated learning and self-determination theory, good feedback practice should provide feedback on the subject and learning practice. However, large groups and lack of time prevents the teacher from providing individual written feedback. In a qualification course in mathematics, we have implemented an assessment practice with immediate feedback that aims to create a dialogue between the lecturer and the students. The feedback is combined with selfevaluation. We also ask the students to reflect on the learning process. Common challenges appearing in the written reflections are then addressed in a subsequent intervention. Today, learners have access to online video lectures that can support learning or in some cases replace lectures. In these online videos, they can watch experts explain a subject and perform calculations with ease. However, watching these instructions or lectures alone might create the illusion of having acquired the skills without having spent the effort. What we see from the students’ self-evaluations and reflections is that they often fail to recognize the difference between understanding a subject and being able to apply the knowledge. Through these assessments, students experience the difference between doing calculations with a textbook or a guide available compared to working on their own. Using what the students write after such assessments are used to introduce what interventions are needed. “I don’t know what happened today, because I know this!” represents an experience that was used to initiate a discussion with the students on the concept illusion of learning.

The study proves the significance of emotional intelligence and self-presentation tactics for the development of personal and professional qualities of a competitive university student. The research pioneers the interconnection between the components of emotional intelligence (the N. Hall test and the D. V. Lyusin questionnaire test Emln) and self-presentation tactics (the S. Lee, B. Quigley scale). The analysis of various points of view on the subject of the study allows us to define emotional intelligence as a combination of cognitive and non-cognitive skills, given the personal characteristics of the individual. Based on this view we can determine the following structural components: perceiving and understanding emotions, managing emotions and using emotions in thinking and other cognitive activities. These components of emotional intelligence influence the optimization of professional training of future psychologists in modern university, whereby they involve the formation of students' professional core competencies enabling them to be competitive in their professional activities. General intelligence is a factor of academic achievements, whereas developed emotional intelligence and self-presentation contribute to the success in life and profession. This research deals with modern educational paradigms, wherein a series of general and specific competencies are translated into particular requirements a professional psychologist is to meet. However, it does not include the students' EI formation and self-presentation abilities necessary for future competitive professionals. The Institute of Psychology and Pedagogy, (Tyumen, Russia) provides the evidence base of the research. The study involves 147 students aged from 17 to 22 (I-IV years of education) majoring in psychology. The research includes three objectives: • to review theoretical and empirical studies in this area; • to diagnose the structural components of emotional intelligence, as well as the students’ selfpresentation tactics; • to carry out a comparative analysis of empirical data and draw conclusions. The survey of the students has shown that the subjects with high and low levels of emotional awareness tend to resort to intimidation and managing emotions as well as such assertive selfpresentation tactics as entitlement and blasting. The students with developed abilities to manage their emotions more frequently manifest their strengths and past achievements. The subjects with low and high abilities to control their emotional states tend to provide negative and critical evaluations of others. The authors emphasize the research prospects of individual human resources where emotional intelligence, as one of the components of the behavioral control, is seen as a predictor of various self-presentation tactics, protective and assertive in particular.

The most recent advancements in cloud computing, highlight the need for supporting deployments on virtualised resources bounded to the dataintensive application requirements and not limited by the strict boundaries of each available cloud provider. Towards this direction, one important challenge is the appropriate protection of the software infrastructure used for automatically performing application components deployment over multiclouds. Specifically, we discuss the requirements and introduce a novel attribute-based access control mechanism, able to cope with potential cybersecurity threats that may compromise the deployment of multi-cloud applications. We attempt to tackle the authorization issues from two different perspectives; namely, coping with the “access control” to various platform components and the “pre-authorization” of application deployment and data placement actions using multiple cloud providers.

Background: Tuberculosis laboratories play an imperative role to achieve the global goal for case detection of smear-positive pulmonary cases. However, tuberculosis laboratories in a low resource setting face numerous quality bottlenecks and hence, achieving the desired case detection target would only be a dream unless continuous monitoring and quality improvement mechanisms are put in place. Therefore, the objective of this study was to assess the quality of tuberculosis laboratory at public health facilities, Sidama zone, southern Ethiopia. Method: A facility based descriptive cross-sectional study was conducted in fifty-six health facilities performing Acid-Fast Bacilli (AFB) microscopy. Data were collected using structured questionnaire and observation checklist. SPSS version 20.0 software was used for data entry and analysis. Descriptive summaries were used to describe the study variables. Results: The overall performance of the tuberculosis laboratories was 48.9%. The lowest score was recorded on training status (19.7%) and the highest score was recorded on biosafety and waste disposal (69.4%). Inadequate performance also identified in infrastructure (28.1%), Standard Operating Procedure’s (49.5%), reagents and equipment (43.5%), maintenance of microscope (42.9%), External Quality assessment (46.8%), internal quality control (25.6%) and data management (57.1%). Conclusion and recommendations: The present study revealed a number of underperformance in the quality of tuberculosis laboratories. To ensure sustainable preventive maintenance of microscope, attention should be given for training and deployment of personnel trained in biomedical equipment maintenance. Laboratory technician should filter Carbol-fuchsin before use and check the quality of stains and staining technique. Training of the laboratory technicians on quality assurance of microscopy would be a good first step to enhance Standard Operating Procedure practice of tuberculosis laboratories.

: This work presents a double asymmetric data hiding technique. The first asymmetry is created by hiding secret data in the complex region of the cover image and keep the smooth region unaffected. Then another asymmetry is developed by hiding a different number of secret bits in the various pixels of the complex region. The proposed technique uses the ant colony optimization (ACO) based technique for the classification of complex and smooth region pixels. Then, the variable least significant bits (VLSB) data hiding framework is used to hide secret bits in the complex region of the cover image. A distance-based substitution technique, namely increasing distance increasing bits substitution algorithm, is used to ensure the asymmetry in the number of hidden bits. The double asymmetric framework enhances the security of the hidden secret data and makes the retrieval of hidden information difficult for unauthorized users. The algorithm results in high-quality stego images, and the hidden information does not attract the human visual system (HVS).

Centro Ciência Viva do Algarve (CCVAlg) is an Interactive Science Museum located in southern Portugal, which mission is to promote scientific and technological culture among the population and especially the youth community. Besides the interactive modules in the permanent exhibition, we design and deploy a wide range of science activities inside and outside our facilities. However, as we are nowadays facing a society (and a science environment) more and more “digital”, the use of technological tools and channels to carry out this mission cannot be ignored, otherwise it will give a biased and obsolete view of today´s reality regarding the techniques and methodologies that the XXI century scientific community uses. On this basis, CCVAlg´s strategy for the last couple of years has been to try to overcome such technological gap introducing and developing new methodologies for our activities. Having this in mind, we approached a Portuguese hardware manufacturer and achieved to forge a partnership that granted 10 detachable tablets with several specific sensors and add-ons that allowed us to design new and innovative outreach activities. The integration of the received devices into the Center´s educational offer allowed us to diversify the pedagogical offer and to involve cerca 3300 participants in the new activities. This type of collaboration reinforces the fact that Science museums should play a key role as strategic partners in the implementation of Information and Communication Technologies (ITC) pilot projects.

: Waveform distortions are an important issue in distribution systems. In particular, the assessment of very wide spectra, that include also components in the 2–150 kHz range, has recently become an issue of great interest. This is due to the increasing presence of high-spectral emission devices like end-user devices and distributed generation systems. This study proposed a new sliding-window wavelet-modified estimation of signal parameters by rotational invariance technique (ESPRIT) method, particularly suitable for the spectral analysis of waveforms that have very wide spectra. The method is very accurate and requires reduced computational effort. It can be applied successfully to detect spectral components in the range of 0–150 kHz introduced both by distributed power plants, such as wind and photovoltaic generation systems, and by end- user equipment connected to grids through static converters, such as fluorescent lamps.

—Software visualization helps software engineers to understand and manage the size and complexity of the objectoriented source code. The tag cloud is a simple and popular visualization technique. The main idea of the tag cloud is to represent tags according to their frequency in an alphabetical order where the most important tags are highlighted via a suitable font size. This paper proposes an original approach to visualize software code using a tag cloud. The approach exploits all software identifier names to visualize software code as a tag cloud. Experiments were conducted on several case studies. To validate the approach, it is applied on NanoXML and ArgoUML. The results of this evaluation validate the relevance and the performance of the proposed approach as all tag names and their frequencies were correctly identified. The proposed tag cloud visualization technique is a helpful addition to the software visualization toolkit. The extracted tag cloud supports software engineers as they filter and browse data.
