The evolutionary development of advanced systems (AS) leads to a necessary rethinking of how they can be supported methodically and in terms of processes in product development. Advanced systems engineering (ASE) offers a novel and holistically adaptive approach to facing such challenges in a structured way. However, many of the ASE use cases relate to the development of systems as products, product networks or individual projects. The additional consideration of entire modular product families within AS offers a further decisive advantage for companies, organisations and the people in ASE. By considering modular product families along the entire life cycle in a product family engineering (PFE), the approaches of ASE can bring their impact and potential to additional system levels occurring when considering product families. The systems, which become complex through variety and collaboration, are broken down into their system elements in a structured way and prepared for a common interdisciplinary understanding, as conveyed by ASE. In this paper, the PFE is presented in excerpts using examples of various aspects and points in time of the product’s life as a complementary approach for ASE.
Chapter 22 introduces the concept of morphology, the study of form which attends to both the uniqueness of individual manifestations of life and the invariable laws which underpin them. Rather than forming a single theory, Goethe’s extensive reflections on morphology emerged in different contexts and run throughout his oeuvre. The chapter examines the most significant stages in Goethe’s engagement with morphology, from his search for the Urpflanze (primeval plant) in Sicily to his development of Anschauung (intuition) as a method, and positions him in relation to other thinkers, above all Wolff and Kant.
A variety is finitely universal if its lattice of subvarieties contains an isomorphic copy of every finite lattice. We show that the 6-element Brandt monoid generates a finitely universal variety of monoids and, by the previous results, it is the smallest generator for a monoid variety with this property. It is also deduced that the join of two Cross varieties of monoids can be finitely universal. In particular, we exhibit a finitely universal variety of monoids with uncountably many subvarieties which is the join of two Cross varieties of monoids whose lattices of subvarieties are the 6-element and the 7-element chains, respectively.
This chapter examines the ways in which pre-war drama explored growing fears over major international conflict. Works considered include Du Maurier’s An Englishman’s Home (1909), Zangwill’s The War God (1911) and a number of less well-known plays and comic skits. The chapter contextualises these works in relation to the fraught geopolitical landscape in which they were produced and the wider cultural phenomenon of ‘invasion fiction’. Both critical and public reactions to these productions are also examined. The chapter concludes by exploring how the pre-war plays established the play-book for propagandistic war-time drama as theatre mobilised for the war effort.
This chapter emphasises the key role that comic revues and music hall acts played in ensuring the British army had a continuous stream of recruits throughout the First World War. Through examining the songs, sketches and characters through which this was achieved, the chapter demonstrates the varied strategies used and the ways they drew on earlier modes of performance such as nineteenth-century melodrama. Particular emphasis is placed on the gendered ideology that was implicit in the performances examined, for example in looking at the dramatization of atrocity stories which were circulating in the press and the treatment of women in these plays and wider narratives. The chapter also focusses on music hall songs and performances by male impersonators such as Marie Lloyd. It encourages us to question the simple alignment of propaganda and popular entertainment and offers a more nuanced understanding of these performances through the lens of satire. By doing so, it demonstrates how satirising and parodying wartime experiences provided a release from anxiety. Stage satire and comedy, it concludes, offer a unique perspective on how modern total war saturated public life.
Yield decline has been the hallmark of Ethiopian sugarcane plantations. However, the extent and causes of the decline have not yet been empirically studied, making it difficult to manage the problem. This study aimed at analyzing the long-term yield data (1954–2022) with respect to variety and soil type. Thus, 8,923 records of yield data were summarized and sorted into decades, varieties, and soil types and then analyzed by applying Mann-Kendall and Tukey’s tests. The fields were classified and mapped using ArcGIS 10.3. The results revealed that 69% of the plantation fields were classified as “yield declining,” and the overall rate of decline has been 8.4 quintals ha−1 year−1 (R2 = 0.76). The rate of decline was higher for older than newer varieties and for vertisols than cambiols. Therefore, the older varieties should be micropropagated or replaced with improved ones, and the vertisols should be amended through practices such as green manuring, improved fallows, etc.
Nitrogen fertilizer and water are two major nutrients required for the optimal production of rice worldwide. The utilization of different irrigation techniques to save water and fertigation to maximize rice production has been the main focus. A field experiment was conducted to explore the responses of 16 rice varieties to different irrigation and nitrogen fertilizer regimes. Two nitrogen treatments, 270 kg ha−1 and 225 kg ha−1 (urea N ≥ 46.4%), and two irrigation regimes, 8.7 t ha−1 and 5.22 t ha−1, were applied three times. Plant height and the soil and plant analyser development (SPAD) values were measured throughout the growth period. The total yield and quality characteristics of the rice varieties were also determined. Based on the yield, the 16 rice varieties were divided into three groups: high yield (I), middle yield (II) and low yield (III) using cluster analysis. A positive correlation was found between the growth period and yield of these 16 rice varieties. In the water-deficient regime, the growth period of the 16 varieties was reduced by 1.68–2.93%. Furthermore, nitrogen- and water-deficient regimes had significant effects on the polishing rate, protein content and taste values of all varieties. At maturity stage under these regimes, plant height and chlorophyll SPAD values were decreased by 1.25–6.05% and 1.60–31.48%, respectively. Deficient nitrogen fertilization, along with appropriate irrigation, is an effective method for the efficient utilization of irrigation and fertilizer resources in rice-growing areas.
Seven varieties of forage oats from China were evaluated in the temperate environment of Bhutan for morphological traits, dry matter production, and forage quality. The oat variety Qingyin No. 1 provided a greater plant height (61 cm) and the largest number of tillers per plant (five tillers per plant). The leaf-stem ratio (LSR) was highest for Longyan No. 2 (LSR 0.73). During harvest in late winter, Longyan No. 2 had a greater plant height (64 cm) and the highest number of tillers per plant (seven tillers per plant), followed by Qingyin No. 1. The top three varieties with high LSRs of 1.49, 1.31, and 1.35 were Longyan No. 1, 2, and 3, respectively. In both summer and winter, Longyan No. 2 had the highest forage yields of around 5.00 and 4.00 DM t/ha, respectively. Qingyin No. 1 was the second largest forage producer, with under 5.00 DM t/ha in summer and under 3.00 DM t/ha in winter. For forage quality, Longyan No. 2 and Longyan No. 3 had the highest levels of crude protein (15%) in summer. However, during late winter, the Linna variety had the highest crude protein content (13%). The overall results of the field experiments suggest that Longyan No. 2 and Qingyin No. 1 are promising new oat varieties for winter fodder production in the temperate environments of Bhutan.
Is variety of the spice of life? The present research suggests that the answer depends on the rate of consumption. In three experiments, we find that, whereas a variety of stimuli is preferred to repetition of even a better-liked single stimulus when consumption is continuous, this preference reverses when the satiation associated with repetition is reduced by slowing down the rate of consumption. Decision makers, however, seem to under-appreciate the influence of consumption rate on preference for (and satisfaction with) variety. At high rates of consumption, they correctly anticipate their own, high, desire for variety, but at low rates of consumption people tend to overestimate their own desire for variety. These results complicate the picture presented by prior research on the “diversification bias”, suggesting that people overestimate their own desire for variety only when consumption is spaced out over time.
As Darwin recollects and writes his experience of teeming variety in the Brazilian rainforest, he conflates the roles of descrying natural historian and person of aesthetic sensibility. Thinking and feeling under the influence of eighteenth-century theories of the sublime and beautiful, Darwin writes his way into a dynamic that confounds object and subject and destabilizes the chronology of looking. Beginning with Darwin’s pretheoretical working through of the temporality of aesthetic experience, particularly the aesthetic experience of variety, this chapter illuminates the ways that Darwin’s theorization of variation, as a scene of distributed agency, was entangled with the processes of experiencing, reading and writing about variety—and impacted by the anticipation and reality of being read. The temporality of this multifaceted experience anticipates Darwin’s later conclusions about the place of anticipation itself in evolutionary processes that hinge on aesthetic phenomenology.
Sex. We walk the reader through why it matters to generate variation in a species. The mixing of genes from two sexes will be familiar to most readers as the reason for the uniqueness of each of us, right from the moment of conception. But we give insight on the other, less widely understood, ways that the differences between us come about. This leads to explanation of the early ‘conversations’ between the mother and her embryo that take place, and why they matter. We give some current and long-standing examples of mankind’s attempts to control conception or to encourage it, including the eugenic sterilisation agenda, artificial insemination and pregnancy termination after fetal sex determination. We explore one of the most hotly debated areas of medicine, assisted reproductive technologies, to which many people will relate. We encourage the reader to challenge the way they think about the preconception period, and consider why the responsibility seems to fall on girls and women, with its consequences for gender equality. This leads to the next chapter.
Dual-purpose sorghum response to anthracnose disease, growth, and yield was undertaken in Derashe and Arba Minch trial sites during March–June 2018 and 2019. Five sorghum varieties and Rara (local check) were arranged in a randomized complete block design with four replications. Variety Chelenko exhibited the tallest main crop plant height (430 cm) while Dishkara was the tallest (196.65 cm) at ratoon crop harvesting. Rara had a higher tiller number (main = 6.73, ratoon = 9.73) among the varieties. Dishkara and Chelenko varieties produced 50 and 10% more dry biomass yield (DBY) than the overall mean DBY, while Konoda produced 40% less. Although the anthracnose infestation was highest on the varieties Konoda (percentage severity index [PSI] = 20.37%) and NTJ_2 (PSI = 32.19%), they produced significantly (p < .001) higher grain yield (3.89 t/ha) than others. Under anthracnose pressure, Chelenko and Dishkara varieties are suggested for dry matter yield while NTJ_2 for grain yield production in the study area and similar agroecology.
To examine demographic and dietary correlates of consumption of a variety of fruits and vegetables (FV) among Texas adolescents. Different types of FV are needed for adequate dietary intake of vitamins and phytochemicals for proper development and functioning throughout the lifespan.
Design:
Cross-sectional analysis from the Texas Surveillance of Physical Activity and Nutrition (Texas SPAN) data comparing consumption of a variety of fruit and vegetables by gender, race/ethnicity and region (Texas-Mexico border/non-border).
Setting:
Middle, high schools in Texas.
Participants:
8th, 11th grade Texas adolescents (n 9056 representing n 659 288) mean age 14·8 years.
Results:
Within this sample, mean fruit and vegetable variety scores (0–7) ranged from 2·47 to 2·65. Boys consumed a significantly greater variety of fruit than girls (mean = 1·12 compared with 1·04). Adolescents in non-border regions consumed a greater variety of vegetables and FV compared with those in border regions. FV variety was associated with healthier eating in the full sample, particularly in the highest socio-economic status (SES) tertile. Within the highest SES tertile, a one-unit increase in variety of fruit, vegetable and FV was associated with significant increases (P < 0·001) in a healthy eating measure, the SPAN Healthy Eating Index: Fruit variety (β = 1·33, se = 0·29), vegetable variety (β = 0·90, se = 0·28) and FV variety (β = 0·81, se = 0·19).
Conclusions:
Consumption of a greater variety of FV appears to be associated with a healthier overall diet. Associations of FV variety with healthy eating were most significant in the highest SES tertile. These findings support the need to further examine consuming a variety of FV within healthy eating behaviour.
The paper discusses whether easy-to-read (ETR) German can be classified as a ‘variety’ and/or a ‘register’. It appears to be very difficult to capture the variational status of ETR German within the system of language variation due to its rather artificial, rule-based character. On the other hand, the question of whether the notion of variety or register, or any other notion modelling language variation, is suitable for the linguistic classification of ETR German very much depends on how these notions are defined. Thus the article reveals general difficulties in capturing the functioning of language variation with clear-cut definitions and concepts due to the dynamics and complexity of language variation as such. Nevertheless, the explanatory frameworks of concepts such as variety and register prove to be useful for describing the special variational status of ETR German.
Focusing on the big data elements of cybersecurity, this chapter looks at the landscape of the big data technologies and the complexities of the different types of data, including spatial and graph data. It outlines examples in these complex data types and how they can be evaluated using data analytics.
This book explores how English sentences are constructed. In this introduction, we explain our approach. We describe the current status of English as a global language, why it holds this status, and why it might not be the best choice. We characterize Standard English as a large dialect cluster, mentioning the British and American subvarieties, along with other dialects, while deploring dialect prejudice. Differences between spoken & written English, formal & informal style, and the grammarian’s purposes of describing & advising are addressed.
In the book, we introduce and define many technical terms for grammatical concepts, and here we justify some of our terminological decisions, noting that even familiar terms like noun and verb will be clearly defined, though often in ways new to the reader. We provide examples to show why.
Though many think language is about words, we focus on sentences and the discoverable constraints about how English sentences can and can’t be structured, constraints that every English speaker recognizes. The most interesting thing about grammar is that these constraints aren’t stipulated rules. They can be discovered through investigation.
The transatlantic circulation of circus acts during the late-nineteenth and early-twentieth centuries created opportunities for circus’s somatically spectacular acts to appear on pantomime and variety theatre stages. This chapter assesses a neglected aspect of circus scholarship: understanding how and why circus acts appeared in other popular entertainment forms. Circus, pantomime, and variety cultivated unity through their reliance on novelty. By tracing the performance engagements of a major circus-style act, Lockhart’s Elephants, in iconic variety venues in London, Paris, and New York City, I demonstrate the deep interrelatedness of modern circus and music hall/vaudeville. Performers frequently established and sustained their reputations in these economically powerful cosmopolitan centres, where heightened competition in the leisure marketplace increased circulation of circus performers. Nineteenth-century industrialisation and changing theatre regulations had transformed genres, allowing audiences more opportunity for leisure activities and theatres more opportunity to blur spoken drama and spectacle. The somatic spectacularity of circus acts provided essential counterpoints to pantomime and variety’s dominant performance modes. This dynamic relationship complicates our understanding of circus, pantomime, and variety as distinct genres, pressing scholars to reconsider the relative stability with which we deploy the terms and write their histories.
Built around two visits to Westminster Abbey, this short coda compares early eighteenth-century attitudes to theatrical transitions to William Hazlitt's and Charles Lamb's writing about actors. Both Lamb and Hazlitt emerge as hostile to what I have called the art of transition, as they each denigrate the performance of a character in favour of the study of that figure’s psychological constitution.
Variety was the hallmark of miscellanism, and Clement draws attention to his participation in this miscellanistic aesthetic in programmatic passages on the literary form of his work. He privileges the vocabulary of poikilia,which not only captured the miscellanistic aesthetic of variety but was also a key term in reflection on the problems and possibilities of variety in aesthetic, ethical, theological and pedagogical spheres. Plato and Philo had also given it prominence in their own engagement with ethical and theological problems of variety. Clement addresses the challenge of variety in shaping his project: his three works, Protrepticus, Paedagogus and Stromateis,organise a pattern of Christian formation that cultivates ethical simplicity with a view ultimately to discerning God’s poikilic wisdom and even in the poikilia of Clement’s own text. Whereas previous studies of Clement have wrestled with the philosophical problem of the ‘many and the one’, this chapter shows that that problem also had a significant literary, aesthetic and ethical dimension, better captured by the terminology of poikilia.
‘Miscellany’ is not an ancient genre name. When scholars use the term, they are often vague about the definition and boundaries of the genre, and rely on well-known ‘examples’ that are treated as paradigmatic. Two scholars have sought to define the ‘miscellany’ more closely: Teresa Morgan gave a broad, inclusive definition grounded in the history of educational praxis; William Fitzgerald gave a narrower definition, focusing on the rhetorical characteristics of an elite, literary strand of miscellany-making. Fitzgerald's approach shall be our starting point as we investigate how and why Clement artfully deployed rhetorical tropes, imagery and metatextual observations to thematise his intentional participation in a wider discourse of learned literary miscellanism. But we must also situate his work in relation to particular examples of early imperial prose miscellanies, otherwise we risk lapsing into generalities about an irreducibly diverse group of texts. Plutarch’s Table Talk; Pliny’s Natural History; Gellius’ Attic Nights and Athenaeus’ Deipnosophists are introduced alongside Clement’s Stromateis,as appropriate for comparative study.
