Letter from the Editor

The Motley has arrived! Let us welcome it as a peer, a friend, a colleague and a liberator! Why liberator? Because it comes to liberate the best academic work that our undergraduate students do from the obscurity of professors’ drawers and hard drives, from the secretive passwords of university servers. It comes to bring that work out into the light of day. Yes, there are personal blogs and social media platforms where students could have published their papers before, but the Motley is different. Papers appearing in it have passed muster, and a tough one for that matter. It is not the “likes” of like-minded friends that raise these papers to the top of visibility. It is the vetting performed by people who may agree or disagree with each other, peers and professors alike, and where knowledge, talent and good argument win the day. That is why the Motley is the opposite of an echo chamber. It is after all a motley of topics, views and forms of expression, all of which have only one thing in common – the high standards of quality that they have met. In our present day of fake news, false theorizing, and vacuous influencing, we have learned how important it is to have a steady intellectual anchor like that.   The liberatory mission of the Motley includes taking down the walls that conceal from the eyes of the community what we learn, create and discuss in our classrooms. It will showcase the gems of original analysis and creativity that our undergrads produce. Where else will your grandma get the chance to revel in your brilliant argument illuminating the major communication and cultural issues of society? How else will your future boss learn about your superior powers as analyst, artist and wordsmith? And maybe, just maybe, your opinionated neighbour or your younger cousin will come to understand some of those complex issues in a new way.   While opening our academic spaces to the outside world, the Motley will also work to bring us, their inhabitants, closer to each other. It will reveal what we collectively value, what we find important and for which we strive. It will compel us to work together – as it already has – by creatively combining the efforts of undergraduate and graduate students, faculty, club leaders, librarians, administrators… It will be our collaborative effort, our joint achievement, and our shared pride and joy. We are in it together and we all have a stake to keep it bright, honest, fair and vibrant.  The Motley is marching into the limelight today in shining colour thanks to the tireless work that numerous champions and supporters performed on the backstage for months. Starting a project like this from scratch takes faith, dedication and perseverance. The authors, reviewers and editors of this first issue did not have an established publication outlet to hang their labour and hopes on. They had to take a bold step over the gorge that separates an idea from its realization. And they did a gorgeous job at that! The Motley knows it was all these contributors who breathed life into it, and it is their example that will inspire and instruct others down the road.   Of all those to whom the Motley will remain forever grateful, one name should be flashed across its first page – Melissa Morris. As its first managing editor, Melissa managed the Motley Undergraduate Journal into existence. She brought together people and computer systems, navigated publication formats and citation styles, wooed, nudged and nagged. She convinced all of us that the Motley was possible, and sure enough, it is here – to stay.   Now, it is your turn, the Motley’s first readers. The Motley team expects you to do your job diligently and devotedly. Read, view, discuss, criticize! Then come and join us as authors, reviewers and editors - a motley of powers, all in your hands! &nbsp

Social Media Tools on the Eve of E-Learning 3.0

In the present paper, we2019;ll explore how social media tools provide an opportunity for new developments of the e-Learning in the context of managing personal knowledge. There will be a discussion how social media tools provide a possibility for helping knowledge workers and students to gather, organize and manage their personal information as a part of the e-learning process. At the centre of this social software driven approach to e-learning environments are the challenges of personalization and collaboration. We2019;ll share concepts of how organizations are using social media for e-Learning and believe that integration of these tools into traditional e-Learning is probably not a choice, but inevitability. Students2019; Survey of use of web technologies and social networking tools is presented. Newly developed framework for semantic blogging capable of organizing results relevant to user requirements is implemented at Varna Free University (VFU) to provide more effective navigation and search

Some aspects of application of software agents in information retrieval in virtual– based educational environments

The problem of information retrieval has attracted increasing attention in recent years. The amount of information sources via networks has grown and is still rapidly growing. Although existing search engines provide rapid retrieval systems, they give limited assistance to consumers in finding the relevant information they need. Intelligent software agents prove to be the necessary tool in improving the effectiveness and efficiency of retrieval. The paper presents concepts about software agents and discusses their advantages in optimizing the retrieval process. This study explores the application of software agents in information retrieval processes in web-based applications for online learning systems. The research was done at Technical University of Varna, and an interactive system new for Bulgaria is proposed.Education for the 21 st century - impact of ICT and Digital Resources ConferenceRed de Universidades con Carreras en Informática (RedUNCI

The personalization of engagement: the symbolic construction of social media and grassroots mobilization in Canadian newspapers

This article explores the symbolic construction of civic engagement mediated by social media in Canadian newspapers. The integration of social media in politics has created a discursive opening for reimagining engagement, partly as a result of enthusiastic accounts of the impact of digital technologies upon democracy. By means of a qualitative content analysis of Canadian newspaper articles between 2005 and 2014, we identify several discursive articulations of engagement: First, the articles offer the picture of a wide range of objects of engagement, suggesting a civic body actively involved in governance processes. Second, engagement appears to take place only reactively, after decisions are made. Finally, social media become the new social glue, bringing isolated individuals together and thus enabling them to pressure decision-making institutions. We argue that, collectively, these stories construct engagement as a deeply personal gesture that is nevertheless turned into a communal experience by the affordances of technology. The conclusion unpacks what we deem as the ambiguity at the heart of this discourse, considering its implications for democratic politics and suggesting avenues for the further monitoring of the technologically enabled personalization of engagement

Proteolytic system of blood flukes of the genus Schistosoma

Krevničky rodu Schistosoma jsou parazitické motolice způsobující onemocnění zvané schistosomóza, které postihuje přes 200 milionů lidí v tropech a subtropech. Dospělé krevničky žijí v cévách člověka a živí se krví. Pro růst, vývoj a rozmnožování krevniček jsou zásadní živiny získané degradací hlavního krevního proteinu hemoglobinu. Za jeho trávení zodpovídá proteolytická výbava trávicího traktu kevniček, která je tvořena sadou enzymů z tříd cysteinových a aspartátových proteáz a metaloproteáz, které mají komplementární specifitu. Proteolytické enzymy hrají důležitou roli i při dalších procesech jako je průnik krevniček do hostitele, migrace tkáněmi, překonání imunitního systému a modulace zánětu. Mezi významné proteázy, které se účastní těchto procesů patří enzymy ze třídy serinových a cysteinových proteáz. Vzhledem k tomu, že proteolytický systém je nezbytný pro životaschopnost krevniček, je v současné době předmětem intenzivního výzkumu zaměřeného na vývoj nových vakcín a chemoterapeutik pro léčbu schistosomózy.

Adult schistosomes live in human blood vessels and feed on blood. Critical nutrients required for growth, development and reproduction of schistosomes are obtained from the major blood protein haemoglobin. Its digestion is mediated by the proteolytic arsenal of the schistosome digestive tract, which includes enzymes with complementary specificity belonging to the classes of cysteine and aspartic proteases, and metalloproteases. Proteolytic enzymes also play an important role in other processes, such as host penetration, tissue migration, immune evasion and modulation of inflammation. Here, serine and cysteine proteases importantly participate. The proteolytic system is essential for the viability of schistosomes and is a current topic of intense research focused on the development of new vaccines and chemotherapeutics for the treatment of schistosomiasis.
