The aim of this point of view paper is to discuss the challenges and opportunities in teaching and research in the field of human physiology in Ethiopia. The challenges are seen as low availability of physiology teachers, especially those that have PhDs, low research productivity, absence of grants for basic sciences and brain drain. Opportunity for improvement is seen in the emergency of more medical schools in the country. However, close attention to standards of quality, particularly the provision of the full range of inputs required to support teaching and research, is urged.

Useful attempts to shed light on the nature of gastronomy from a scientific point of view and to unravel the crucial connection between food, eating and well-being are currently underrepresented in the scientific literature. However, several scientific disciplines ranging from the natural to the social sciences offer valuable new perspectives on gastronomy. As one of the key disciplines in natural science, physics offers original and rigorous perspectives on all processes and structures constrained by the laws of nature. The emerging discipline called gastrophysics employs the full range of concepts, techniques and methods from physics to generate useful scientific input to the complex and holistic reflections on gastronomy. Relying on a review of the existing literature, this article illustrates how a science-based gastrophysics emerges, to a large extent from the convoluted history of food science as well as from various recent – and often overlapping – attempts to combine modern scientific methodology to questions from gastronomy. However, the present review also insists on a physics-inspired methodology to handle scale and complexity in food preparation and consumption across length scales from sub-molecular to entire foods. We exemplify how gastrophysics directly helps to develop gastronomy and how it adds to current approaches in traditional food science. We also suggest that gastrophysics may prove relevant in the context of the ongoing food transformation, which focuses strongly on sustainability, but where the importance of gastronomic aspects in this transformation is greatly needed.

Analysis of profiles of minors in social networks shows that teenagers indicate in them information that increases the level of their social desirability. Such information often does not correspond to the real behavior of the teenager. For a full analysis of the level of deviance of a minor need tools covering the full range of indicators. In contrast to the usual approach to clustering objects based on their Association in groups by the criterion of the minimum distance in multidimensional space when clustering features it is advisable to take into account their proximity to the methods of obtaining information and methods of processing of this information by the inspector for minors. In the first phase of the study is the clustering of signs of deviation, the second the determination of the weighting factors of indicator of the degree of deviance within each group of signs, the third uses the method of cluster-hierarchical approach to forming integral indicator of assessment of deviant behavior of minors. The indicator has a considerable flexibility of the correlation between groups of symptoms and partial characteristics through the introduction of appropriate sets of weighting coefficients. The conclusion is made about the preference of methods based on clustering of objects in the two-dimensional space of targets or accounts of the principal components method, as well as the need for additional analysis of the graphical picture of the relative location of objects. From the comparison of different approaches: 1) clustering on the basis of the generalized indicator of quality and the sign of reverse deviance, 2) clustering on two accounts of the principal components method; 3) clustering on all signs of examination, the following conclusions can be drawn. All methods properly allocate the objects to clusters. However, when you save the main totals (highlighting the best and worst features), the results are slightly different. This is due to the different volume and forms of presentation of the source information. The program assigns numbers of active neurons (clusters) arbitrarily, so in order to arrange the cluster numbers by some feature (for example, the quality of objects), you need to use additional graphical information. From a practical point of view, the first two methods are preferred, based on clustering objects in two-dimensional space, the method of principal components and the analysis of the graphical picture of the mutual location of objects.

Introduction. In scientific literature dedicated to J. Brahms, much attention has been paid to a song genre. The researches note that J. Brahms’s songs can be regarded as a continuation of genre-specific features of Austro-German Lied, which retains the purity of the generic semantics in the composer’s works, without involving typically operatic means of vocal intoning, or approaching the so-called “poem with music”. J. Brahms’s songs do not allow the singer to demonstrate the full range of his/her voice, to reveal his/her artistic temperament, to show the technical skill. Absorption in a special emotional aura of J. Brahms’s songs requires a variety of timbre-intonational resources of a singer, his/her ability not to lose the sense of the whole while detailing the melodious overture. Of particular interest is the issue of music and words correlation in J. Brahms’s songs. As a rule, the composer is considered to be the immediate successor of F. Schubert rather than R. Schuman in his orientation to musical embodiment of a generalized poetic image. At the same time, this issue requires more detailed study, since the composer was very sensitive to the poetic text, in particular, from the point of view of coordinating the intonation-phonetic features of German language and vocal intonation. Theoretical Background. Recent research and publications analysis. Opus 49 by J. Brahms seems to be in the shadow of musicological thought and performing practice. It should be noted that a very famous opus part is “Lullaby”, which is mentioned in the monographs of K. Tsareva (1986), M. Druskin (1959), and K. Geiringer (1965). In the literature being considered the abovementioned opus is not completely covered, thus determining the relevance of our article. There are references to individual songs in different sources, but incidentally, in the context of different issues. Objective is to study J. Brahms’s opus 49 in the aspect of the interaction of poetic word and music, verbal and musical intoning. Methods: 1) historical method, allowing to comprehend the selected material in the perspective of the development of Austro-German song of the XIX century; 2) intonational method, which involves the study of vocal melody in terms of phonetic-tonic links; 3) genre method, caused by the features of chamber vocal lyrics; 4) stylistic method, corresponding to a specific opus consideration in the general context of the composer’s creative work. Results and Discussion. The composer did not have any tendency to the songs cyclization, however, the vocal miniatures, assembled in one opus, appear to be lyrical notes, self-contained but united by poetic motives and nature of the author’s expression. Many researchers see a cyclic organization of his particular vocal opuses. For example, I. Mykhailov (1987: 19) proves the existence of cyclic principles at different compositional levels in composer’s songs: separate “melodious pairs”, a number of songs with the texts by one poet inside the opus, a whole vocal opus with the texts by different authors. According to I. Mikhailov, the cyclic connection of songs is emphasized by several compositional techniques: thematic one, i.e. the unity of the musical material; the continuity of songs alternation, which is sometimes manifested in the absence of a piano introduction of the next song. In opus 49, the author chooses different poetic sources – poems by P. Heyse, L. Hölty, A. F. Schack, and J. Wenzig. The composer refers to one of the samples of the famous collection by Joachim von Arnim and Clemens Brentano “The Magic Horn of a Boy”. Given the anthological principle of poetic texts selection, no transparent storyline in opus 49, such as “A Beautiful Miller” by F. Schubert or “Poet’s Love” by R. Schumann, there is no reason to regard it as a cycle. However, the opus’ songs are arranged in a certain semantic sequence. Owing to the fact that three songs (“Sunday Morning”, “To a Violet”, “Longing for the Sweetheart”) are united by homogeneous poetic motifs, one can regard them as forming a microcycle within the whole. The second micro-cycle of the opus is represented by No. 4 and No. 5 (“Lullaby” and “Twilight”). In interpreting the poetic text, J. Brahms adheres to the principle of emotional and musical generality, once detailing the text, if at all. Here, he succeeds F. Schubert. However, he uses the technique of keywords, distinguishing them in two ways: rhythmically (with syncope) and through intrinsic chants; the composer also uses different types of intoning. Following the tradition of the 19th-century Austro-German song, the composer regards the genre as an alliance of two full members: the vocalist and the pianist, with the part being an instrumental generalization. The intonational image of the whole in vocal music arises at the crossing of two texts – poetic and musical. German has intonation difficulties owing to a large number of consonants. Problems, encountered by the singers in intoning German language, are compensated by the consonants and vowels, which are most favorable for correct sound formation, allowing to achieve the required quality. The soft consonants and vowels should be regarded as the ideal vocal sound, that is, a model for other phonemes in musical-poetic text. While creating vocal melodies of Opus 49 songs, J. Brahms cares the phonetics of a German text in the singing to be comfortable for the performer. Conclusions. J. Brahms uses such principles and techniques of literary original musical embodiment as preservation of the holistic image, created by the author of the poems, on the one hand, and its detailing on the other. In the second case, the composer resorts to all means of musical expression: motive-thematic, texture-register, rhythmic, harmonious, texture ones. The prospects of the research lie in studying the interaction of verbal and musical intonation in other vocal works of J. Brahms, as well as in chamber-vocal music of late romantics.

The importance of diaspora and transnational knowledge production, innovation, and development is of growing interest, particularly in the developing world. The phenomenal increase in high human capital migration from poor to rich countries has historically led to what is commonly known as brain drain, which has negatively impacted the capacity of such countries to innovate. Yet more recently the emergence of the phenomenon of transnationalism has demonstrated the potential to transform brain drain into brain circulation, for the mutual benefit of both sending and receiving contexts. This article uses the case of Zimbabwe to explore the role of diasporan professionals, scholars, and entrepreneurs in contributing to knowledge production, innovation, and development initiatives in their countries of origin. Zimbabwe is an example of many African countries that have experienced substantial attrition of highly qualified knowledge workers for various reasons. A qualitative approach, involving interviews and documentary evidence, enabled the researchers to engage with the Zimbabwean diaspora to capture their narratives regarding the challenges and opportunities, which were then used to develop successful transnational knowledge production initiatives.

Academic certificates have a significant influence on the job market, proving a particular competence or skill of a recipient. However, the ability to verify the authenticity of certificates does not follow its relevance in the labor market, causing several companies to exploit this inefficiency to falsify information or even to make fake certificates. In this context, several proposals based on blockchain appear as a technological alternative to increase the transparency and the ease of verification of these certificates. This chapter discusses the main proposals toward the handling of academic certificates from a technological point of view, discussing the technical aspects that may influence the relationship between confidentiality and transparency as well as application requirements such as performance and reliability in contrast to the blockchain characteristics. Finally, this chapter summarizes the key challenges and opportunities based on this discussion outlining future directions for academic certificate management.

With the type of ailments increasing and with the methods of diagnosis improving day by day, wearable devices are increasing in number. Many times, it is found to be beneficial to have continuous diagnosis for certain type of ailments and for certain type of individuals. One will feel uncomfortable if a number of needles are protruding out of one's body for having continuous diagnosis. From this point of view, wearable diagnosis systems are preferable. With Internet of Things (IoT), it is possible to have a number of diagnostic sensors as wearable devices. In addition, for a continuous monitoring, the information from these wearable devices must be transferring information to some central location. IoT makes this possible. IoT brings full range of pervasive connectivity to wearable devices. IoT of wearable devices can include additional intelligence of location of the person wearing the device and also some biometric information identifying the wearer.
