Land plants host a vast and diverse virome that is dominated by RNA viruses, with major additional contributions from reverse-transcribing and single-stranded (ss) DNA viruses. Here, we introduce the recently adopted comprehensive taxonomy of viruses based on phylogenomic analyses, as applied to the plant virome. We further trace the evolutionary ancestry of distinct plant virus lineages to primordial genetic mobile elements. We discuss the growing evidence of the pivotal role of horizontal virus transfer from invertebrates to plants during the terrestrialization of these organisms, which was enabled by the evolution of close ecological associations between these diverse organisms. It is our hope that the emerging big picture of the formation and global architecture of the plant virome will be of broad interest to plant biologists and virologists alike and will stimulate ever deeper inquiry into the fascinating field of virus–plant coevolution.

The Relationship

Colleges and universities have begun using the language of vocation and calling to help undergraduates think about the future direction of their lives. This language has been employed in both secular and religious contexts, but it has deep roots in a specific theological tradition. Given the increasingly multi-faith context of undergraduate life, many have asked whether this originally Christian terminology can truly become a new vocabulary for higher education. This volume’s 13 contributing scholars identify with a wide variety of faith traditions, including Buddhism, Christianity, Hinduism, Islam, Judaism, and Sikhism. Some claim more than one tradition; others would claim none. Rather than seeking to “translate” Christian language into other perspectives, they reflect on various facets of vocation from the standpoint of their own traditions. Both individually and collectively, they seek to expand the range of vocational reflection and discernment well beyond its traditional Christian origins, addressing themes such as religious pluralism and difference, the importance of multiple voices, the role of affective learning, the relationship between process and result, and the development of an integrated life. The authors recognize that all undergraduate students—regardless of their academic field, religious background, or demographic identity—need to make space for reflection, to overcome obstacles to vocational discernment, and to consider the significance of their own narratives, beliefs, and practices. Accomplishing these goals will require college campuses to reimagine their curricular and co-curricular programming in order to support their students’ interfaith reflections on issues of meaning and purpose, as well as personal identity.

Past Experiences

Immersed in the flow of activities, diplomats and other international practitioners are simultaneously influenced by past experiences and constantly innovating in response to situations that are never exactly the same. The conceptual tools of International Relations scholars must be capable of capturing this practical reality. To that end, I introduce in this article a relational approach to agency that can make sense of practitioners’ innovative ways of doing things in practice. Practice theorists in IR often emphasize hierarchies, struggle, and the role of habitus in shaping practices. Both building on and departing from them, I dig into the logic of practical sense and discuss Pierre Bourdieu’s concepts of regulated improvisations, virtuosos/amateurs, and illusio to grasp agency in practice. I develop the idea that international actors are primarily practical and put improvisations and virtuosity — rather than rationality, cognitive processes, emotions, norm-compliance, path-dependency or even habits/habitus — in the foreground. I contend that this approach holds broader promise for the analysis of international politics than existing conceptions. We have much to gain by focusing on how international practitioners in their local contexts actually improvise in the moment. These improvisations in specific sites are constitutive of the ‘big picture’ of international politics. I take diplomatic practices in embassies and in permanent representations as an illustration.

The article deals with the main issues of the process of transforming of onomastic units into figurative words in the poetic language. Here, the possibility of creating onomastic units, based on concrete examples derived from Kurgoglu's poems, has been analyzed. The linguistic basis of the image created by the onomastic units in the poetry language has been studied in a wide aesthetic system. The role of onomastic materials in poetic thinking in a certain direction in the activity of national sources and deep roots of poetic language was paid attention.

Abstract Background Several DNA viruses are highly suspicious to have oncogenic effects in humans. This study investigates the presence of potentially oncogenic viruses such as SV40, JCV, BKV and EBV in patient-derived colorectal carcinoma (CRC) cells typifying all molecular subtypes of CRC. Methods Sample material (gDNA and cDNA) of a total of 49 patient-individual CRC cell lines and corresponding primary material from 11 patients, including normal, tumor-derived and metastasis-derived tissue were analyzed for sequences of SV40, JVC, BKV and EBV using endpoint PCR. In addition, the susceptibility of CRC cells to JCV and BKV was examined using a long-term cultivation approach of patient-individual cells in the presence of viruses. Results No virus-specific sequences could be detected in all specimens. Likewise, no morphological changes were observed and no evidence for viral infection or integration could be provided after long term CRC cell cultivation in presence of viral particles. Conclusions In summary, the presented data suggest that there is no direct correlation between tumorigenesis and viral load and consequently no evidence for a functional role of the DNA viruses included into this analysis in CRC development.

Imre Magyar, the last great representative of the Korányi School, who was appointed as the director and professor of the Internal Medicine Clinic I of the Budapest University of Medicine in 1965, emphasised in his inaugural address that from the three closely intertwined functions of the university clinic, i.e. patient care, research and medical training and education, he considers the latter the most important. The study intends to present that Imre Magyar, as an absolute educator, pursued this objective until his retirement in 1980. In his inaugural address he regarded lectures given by teachers of higher calibre with the intention to teach students medical thinking as one of the most important components of education. He even looked at lectures rather as seminars, never forgetting to make presentations on patients. Textbooks were meant for home education. Magyar, however, also “provided assistance” with this for medical students. His functional holistic thinking made it possible that medicine as specialised sciences be once again summarised as a uniform internal medicine dealing with the whole individual in his textbooks co-written by Petrányi and used in medical training for decades. Making a concrete connection with the patient, appropriate verbal and metacommunications, empathy, understanding and showing appropriate medical behaviour were, in his view, prerequisites for becoming a doctor. That is why he was concerned about the function of the doctor’s character in healing, and conducted investigations also described in this study on several occasions in relation with the cultivation of medical students. That is why Imre Magyar, who saw the big picture of education, emphasised the vital role of literature, arts and music in a doctor’s life.

Core Value

Across the country, American mosques are struggling with dwindling attendance and/or stagnancy. The causes generally come back to four interconnected points: a lack of governing principles, the politics of control by personalities, little focus on social integration, and a scarcity of properly trained and empowered imams. The imam, the community’s leading inspirational motivating force, is governed by scripture and both supported as well as held accountable by a community rooted in scriptural values. These values are a broad realm of massive differences subject to an array of cultures that can be a cause for division. Given this reality, Muslims must establish a mission, vision, and core value system for a clear cohesive divinely guided community. This system must priori-tize the community’s relevant needs with a strong focus on the big picture of Islam as it relates to the broader society. The administrative management of mosques should support their imam to lead them accordingly.

Green Lineage

Streptophytes are one of the major groups of the green lineage (Chloroplastida or Viridiplantae). During one billion years of evolution, streptophytes have radiated into an astounding diversity of uni- and multicellular green algae as well as land plants. Most divergent from land plants is a clade formed by Mesostigmatophyceae, Spirotaenia spp. and Chlorokybophyceae. All three lineages are species-poor and the Chlorokybophyceae consist of a single described species, Chlorokybus atmophyticus. In this study, we used phylogenomic analyses to shed light into the diversity within Chlorokybus using a sampling of isolates across its known distribution. We uncovered a consistent deep genetic structure within the Chlorokybus isolates, which prompted us to formally extend the Chlorokybophyceae by describing four new species. Gene expression differences among Chlorokybus species suggest certain constitutive variability that might influence their response to environmental factors. Failure to account for this diversity can hamper comparative genomic studies aiming to understand the evolution of stress response across streptophytes. Our data highlight that future studies on the evolution of plant form and function can tap into an unknown diversity at key deep branches of the streptophytes.

This chapter will explore the similarities and differences between late nineteenth-century debates on the British settler Empire and more recent visions of the Anglosphere. It suggests that the idea of the Anglosphere has deep roots in British political thought. In particular, it traces the debates over both imperial federation and Anglo-American union from the late nineteenth century onwards into the post-Brexit world. I examine three recurrent issues that have shaped arguments about the unity and potential of the ‘English-speaking peoples’: the ideal constitutional structure of the community; the economic model that it should adopt; and the role of the United States within it. I conclude by arguing that the legacy of settler colonialism, and an idealised vision of the ‘English-speaking peoples’, played a pivotal role in shaping Tory Euroscepticism from the late 1990s onwards, furnishing an influential group of politicians and public intellectuals, from Thatcher and Robert Conquest to Boris Johnson and Andrew Roberts, with an alternative non-European vision of Britain’s place in the world.

This article describes the development of a trans-disciplinary framework for creative teaching using technology. In recent years, the authors of this paper (and collaborators) have sought to better understand the role of creativity in educational technology. Our approach seeks to inform theory, research, and practice. In this piece we step back to provide a big-picture view of the process of developing a theoretical framework for creative, transformational teaching with digital technology. We describe the development of our ideas over time, through research projects focused on highly creative teachers and their practices. We describe how we have applied these ideas in teacher education courses devoted to creativity and technology, and developed rubrics for evaluating creative products. At a meta-level we aim to provide a rich example of the reciprocal nature of theory, research, and practice in educational technology. Through this we hope to provide one example of how such a theory/research/practice development process works, with the goal of informing future work of this type.
