Past surveys are described in the logical sequence of (1) comets visually, (2) asteroids visually, (3) asteroids photographically and (4) comets photographically. Plots show the evolution of asteroid surveys in terms of visual discovery magnitude and ecliptic latitude, and similarities and differences between surveys for the different types of body are discussed. The paper ends with a brief discussion of more recent discovery methods and some thoughts on the future.

This paper is devoted to the participle system in Bulgarian and Greek, presenting in a comparative plan the formation, meanings, functions and use of the different types of participles in the two languages. The paper focuses on the similarities and differences in the different types of participles, giving information about the frequency of their use in both languages. The traditional types of active and passive participles are considered separately. However, for some of the types of participles there are different opinions whether they should be included in the participle systems of the two studied languages, the article presents the relevant views and arguments of researchers. Such are, for example, the past imperfect active participle and the present passive participle in the Bulgarian language, as well as the present active participle and the aorist active participle in Greek. The present study is the first attempt to present the participle system in Bulgarian and Greek, with the comparison made at the system level in both languages. Apart from the theoretical plan, the conclusions formulated as a result of the comparative study of the participle systems of the two languages would be useful in practice in the assimilation of certain types of Greek participles by Bulgarians learning Greek. In the future, the field of study could be expanded into the comparative analysis of the participle system in Bulgarian and Greek at the level of speech (for example, on the basis of a translation corpus).

The design of Pfizer/BioNTech and Moderna mRNA vaccines involves many different types of optimizations. Proper optimization of vaccine mRNA can reduce dosage required for each injection leading to more efficient immunization programs. The mRNA components of the vaccine need to have a 5’-UTR to load ribosomes efficiently onto the mRNA for translation initiation, optimized codon usage for efficient translation elongation, and optimal stop codon for efficient translation termination. Both 5’-UTR and the downstream 3’-UTR should be optimized for mRNA stability. The replacement of uridine by N1-methylpseudourinine () complicates some of these optimization processes because is more versatile in wobbling than U. Different optimizations can conflict with each other, and compromises would need to be made. I highlight the similarities and differences between Pfizer/BioNTech and Moderna mRNA vaccines and discuss the advantage and disadvantage of each to facilitate future vaccine improvement. In particular, I point out a few optimizations in the design of the two mRNA vaccines that have not been performed properly.

This article develops a framework for applying organizational narrative theory to understand project narratives that potentially perform and change the future. Project narratives are temporal but often get repeated throughout the project life cycle to stabilize meaning, and could be about project mission, vision, identity, value creation, and so forth. Project narratives have important implications for organizational identity and image crafting. This article differentiates among different types of project narratives in relation to a project life cycle, providing case studies of project narratives on three major UK rail projects. We then set out the future research agenda into project narrative work.

Much of the present debate about content on the internet revolves around how to control the distribution of different sorts of harmful or undesirable material. Yet there are considerable issues about whether sufficient sorts of desired cultural content will be available, such as ‘national’, ‘Australian’ content. In traditional broadcasting, regulation has been devised to encourage or mandate different types of content, where it is believed that the market will not do so by itself. At present, such regulatory arrangements are under threat in television, as the Productivity Commission Broadcasting Inquiry final report has noted. But what of the future for certain types of content on the internet? Do we need specific regulation and policy to promote the availability of content on the internet? Or is such a project simply irrelevant in the context of gradual but inexorable media convergence? Is regulating for content just as quixotic and fraught with peril as regulating of content from a censorship perspective often appears to be? In this article, we consider the case of Australian content for broadband technologies, especially in relation to film and video, and make some preliminary observations on the promotion and regulation of internet content.

If schools are to prepare students to participate more productively in civic life, schools will need to ensure that they have opportunities to practice the skills of civic reasoning, argues Carol Lee. Yet schools are challenged by the limits in the curriculum and the difficulty of addressing the different types of prior knowledge that students bring to the classroom. Lee suggests that when schools build their content and pedagogy on current understandings of human learning, they will be better able to enable students from all backgrounds to practice building the understandings they need, now and in the future.

Recently transposition became the issue of many research papers for being a complicated and sophisticated language phenomenon, and its definition has been broadened. The issue of transposition and the degrees of verb transitivity are the most controversial and difficult ones both in Hungarian and Russian linguistics. This issue may be investigated on different language levels: lexical, syntactic, morphological and on the level of word formation. Taking into account the mobility of parts of speech boundaries in the compared languages we attempt to find the cause of words transitioning from one lexico-grammatical class into another, investigate transposition as a natural phenomenon both for the Hungarian and Russian languages, differentiate transition in parts of the speech system from other language phenomena, solve some contentious issues regarding parts of speech, for example ‘noun-adjective’ relations, and others. Despite having extensive literature concerning nominalization in Russian linguistics and some works in Hungarian linguistics, some aspects are not comprehensively covered in them. For example, different types of transitions from other parts of speech into nouns, thorough semantic and thematic categorization of substantivized words, characteristics of their functioning in texts of different functional styles, principles of creating lexicography, etc. In this article we compare the process of substantivation amidst the system of parts of speech in languages of such different structure as Hungarian and Russian. Comprehensive and comparative study of the process of transition of other parts of speech into nouns allows us to conduct a deeper investigation of each of these languages’ structure and also to reveal typological similarities and differences between them. These languages have not been explored this way so it provides scientific novelty to the research. For the first time we define the main conditions of a systematic process of transposition in Hungarian and Russian and reveal both specific and universal opportunities for transition in the compared languages. We use comparative analysis for researching semantic models of substantivized words, distinguish different types of transitions into nouns and describe structural and stylistic features. Thus, the topic of the research is the grammatical, semantic, structural and stylistic features of substantivized words in Hungarian and Russian. The objective of the study is to discover linguistic nature of substantivation of adjectives, verbs and verbal formations, numerals and pronouns, to find out specific and universal features caused by typological differences of the researched languages. To achieve this goal we need to solve the following problems: determining the place of substantivation in the system of word formation in Hungarian and Russian, discovering how much substantivation and conversion being productive ways of word formation are identical in Russian and Hungarian, distinguishing semantic models of substantivized words and compare them, comparing models of usual and occasional substantivation and determine its productivity, studying their structure which means showing peculiarities of substantivized words’ grammatical structure in Hungarian and Russian, discovering similarities and differences between them and finding adequate models. The research is based on data of dictionaries of Russian and Hungarian languages, examples of fictional texts, live speech and not the least on the idioms. Theoretical importance lies in the following: 1) the research develops the theory of transitivity as we study transposition in two languages of different structures using comparative analysis of substantivized words and taking into account grammatical, semantic and functional aspects; 2) using the materials of two languages of different structures we discover the main conditions of systematic transposition and distinguish its universal and specific features; 3) for the first time the problem of transposition is studied on the basis of Russian and Hungarian from a theoretical point of view (on the example of transition of other parts of speech into nouns); 4) we develop the methodology of a comprehensive approach to study substantivation in Hungarian and Russian which can be used when describing this phenomenon in other languages of different structures.

This paper examines major Swedish school digitalization curriculum reforms over the past 50 years by analyzing similarities and differences between the late 1960s, mid-1990s, and early 2010s curricular reforms. By drawing on Jasanoff’s (2015) socio-technical imaginary concept, we examine how digitalization reforms are constituted discursively and materially in struggles over curricular knowledge content, preferred citizenship roles, and infrastructural investments and especially by relating curricular reforms to governance transformations. One recurrent strategy of reform is what we call the back to the future argument, where curricula address an ideal citizenship of future societies, politically used to support change. We suggest that in the more than 50 years of school digitalization issues, it has been surrounded by strong and shifting struggles over the curriculum content and governance transformations. This pendulum movement (Englund, 2012) has taken place partly through central, state-led or new monopolized technology governance and infrastructures and partly through decentralized forms of governing (e.g., in municipal contexts and via IT-supported networks).

The aesthetics of fashion can be regarded as the aesthetics of novelty since constant changes make novelty the core of fashion. Based on Colin Campbell’s theory, novelty is a judgment about our subjective experiences, indicating something we never experienced before. In the early stage of the fashion system, designers led fashion trends by creating brand-new items or borrowing foreign elements. Then, as the pace of fashion circulation increased, designers started to produce novelty by modifying details, or by repeating what was in fashion long before. Hence, fashion became cyclical. And the cycle duration would become shorter and shorter as the repetition sped up. At this stage, novelty is not based on whether the item is brand-new, but whether we still remember it. In the future, maybe the repeating of the old cannot maintain the feeling of novelty any more since the pace of fashion change is too quick to give enough time for the new to become old and forgotten. At that time, the novelty will not be based on whether we still remember it, but whether we want to forget it. Therefore, with the acceleration of fashion change, the method of how fashion produces novelty has gone through a logical sequence as follows: creating something brand-new, borrowing foreign elements, modifying details, repeating the forgotten old, and forgetting what is still new. Novelty has gone through a process from ‘externally determined’ to ‘internally determined’, moving to the direction of ‘self-deception determined’. Article received: April 20, 2019; Article accepted: June 15, 2019; Published online: September 15, 2019; Original scholarly paperHow to cite this article: Ruhan, Liao.
