Monooxygenases are a class of enzymes that facilitate the bacterial degradation of alkanes and alkenes. The regulatory components associated with monooxygenases are nature’s own hydrocarbon sensors, and once functionally characterised, these components can be used to create rapid, inexpensive and sensitive biosensors for use in applications such as bioremediation and metabolic engineering. Many bacterial monooxygenases have been identified, yet the regulation of only a few of these have been investigated in detail. A wealth of genetic and functional diversity of regulatory enzymes and promoter elements still remains unexplored and unexploited, both in published genome sequences and in yet-to-be-cultured bacteria. In this review we examine in detail the current state of research on monooxygenase gene regulation, and on the development of transcription-factor-based microbial biosensors for detection of alkanes and alkenes. A new framework for the systematic characterisation of the underlying genetic components and for further development of biosensors is presented, and we identify focus areas that should be targeted to enable progression of more biosensor candidates to commercialisation and deployment in industry and in the environment.

This article maps out recent developments in the exegetical investigation of Jesus. It starts with a discussion of the Jesus book by Joseph Ratzinger/Benedict XVI, in which ‘canonical exegesis’ is used to argue that Johannine Christology is also present in the other gospels and that this Christology actually goes back to Jesus. In this way, the book narrows the gap between the historical Jesus and the Christ of faith. The next section argues for maintaining the multiplicity of images of Jesus as a literary figure that is the fruit of relatively recent approaches: redaction criticism, narrative-semantic analysis and intertextuality. The final section contains a sketch of the current state of research on the historical Jesus and its relevance for Christology. The multiplicity in the literary and historical approaches poses challenges to the further development of Christology.

Objective: To provide an overview of concepts of operation for single pilot operations (SPO) and a synthesis of recently published work evaluating these concepts. Background: Advances in technology have made it possible for a commercial aircraft to be flown by a single pilot under normal conditions, and research is being conducted to examine the feasibility of implementing SPO for commercial aviation. Method: Context leading up to the consideration of SPO for commercial flight is provided, including the benefits and challenges. Recent studies examining issues relating to automation, operations, and communications in the SPO context are presented. Results: A number of concepts have been proposed and tested for SPO, and no one concept has been shown to be superior. Single pilots were able to successfully resolve off-nominal scenarios with either the ground-support or cockpit-automation tools examined. However, the technologies developed in support of these concepts are in prototype forms and need further development. Conclusion: There have been no obvious “show stoppers” for moving toward SPO. However, the current state of research is in its initial stages, and more research is needed to examine other challenges associated with SPO. Moreover, human factors researchers must continue to be involved in the development of the new tools and technologies to support SPO to ensure their effectiveness. Application: The research issues highlighted in the context of SPO reflect issues that are associated with the process of reducing crew members or providing remote support of operators and, more generally, human interactions with increasingly autonomous systems.

From 20 to 27 August 2018, the International Slavic Congress took place in Belgrade. The pro-gram of the Commission held meetings that are accredited (affiliated) at the International Committee of Slavists. The congress of researches on emigration provided an opportunity to discuss the current state of research and their prospects for further development. The author of the article discusses the specifics of emigration research, paying particular attention to the achievements of Polish stud-ies, and points out the most important tasks facing the Board and the Bureau of the Commission. An important stage in the activities of the commission is the decision to move its headquarters to Olsztyn, which strengthens the Institute of Eastern Slavic studies as one of the Leading centers of emigration research, not only in Poland, but also in European science.

The current state of research regarding the history of the Polish studies at Czech universities is mainly reflected in collective monographs, published to celebrate the 90th anniversary of their founding. The conducted analyses revealed the current state of the Czech Polish studies, traditionally developing in academic centres in Prague, Brno, Olomouc and Ostrava, and of specific determinants that the entire foreign Polish studies are subject to. Debate on further development of Czech interdisciplinary studies of Poland was held also within the framework of the 1st Congress of the Czech Polish Studies. The authors believe that further research should pay more attention to the genesis of Czech institutionalized Polish studies, especially on the period when their precursors were active. It is also necessary to put the research in the context of the interest in the language, literature, history and culture of the Slavs, which started to emerge in the period of the Czech National Revival.

The review of V.K. Shokhin’s monograph examines the current state of research in practi­cal philosophy. It is noted that practical philosophy today undergoes a deep crisis due the lack of thorough research that would clarify its foundations and structure. The reviewed monograph serves as a timely filling of this apparent gap. The review covers the structure of the monograph, its main ideas, and conclusions to which V.K. Shokhin comes. The positive aspects of the work are examined in detail. Special attention is drawn to the universality and fundamental character of the study, to the scale of the tasks set by the au­thor most of which find their resolution in the course of the study. The thoroughness of the historical part of the study devoted to a discussion of the main representatives of Western philosophy as well as ancient Indian and ancient Chinese philosophical views is emphasized in a special way. Some polemical remarks and wishes regarding the further development of the author's research in this area are expressed. It is noted that the re­search will be of interest not only to the narrow circle of specialists in ethics but also to a general audience.

Purpose: This paper is a thematic literature review to examine the current state of research about Culturally Responsive Pedagogy in mathematics. The main themes are students’ perception, teacher education for pre-service teacher and professional development for teachers. Research methods/ approach: Literature was collected from Eric, which is a research engine of the education field. Also, Google Scholar is used to find articles of major scholars introduced by Dr. Rich Milner, who is the instructor of this course. Findings: Students faced microaggressions in mathematics class, which discouraged them to learn mathematics. The effect of teacher education was inconsistent in terms of the awareness of culturally responsive pedagogy and lesson plans. Research of professional development mentioned that mathematics was cultural. Implications for research and practice: It is more interesting to conduct long term or follow-up research to find the teacher’s practice after a taking professional development program. Also, it is critical to expand research scope besides African American and Latino students. Finally, evidence-based research is needed to change the political situation. Keywords: culturally responsive teaching, mathematics, teacher education, professional development, student’s perception

The expansion of human knowledge in all areas is largely the outcome of the activity of academic institutions and the result of their mission to contribute to the cultural, intellectual and economic development of the society, involving education, research and university extension activities. For many years, the academic community has been organizing itself in all different ways to respond to current and future needs, ensuring research integrity and recognition, and building on successive generations of peers to validate and support the launching and development of novel research streams. We owe the current state of research and development of our society to generations of scholars and scientists that have brought all of us here.(...)
