Concision is about more than writing like Hemingway or following Strunk & White’s edict to eliminate unnecessary words. Instead, concision relies on writers recognizing the myriad redundancies in English, a reflection of its evolution from the collision of Latin, French, and Old English in the decades following the Norman Conquest. Moreover, redundancies also litter English in the form of redundant modifiers, throat-clearing, and metadiscourse. By recognizing these words and phrases, writers can quickly pare sentences to their essentials, without fretting over the havoc deletions can wreak on the meaning of their sentences.
We report findings from a corpus-based investigation of three young children growing up in German-English bilingual environments (M = 3;0, Range = 2;3–3;11). Based on 2,146,179 single words and two-word combinations in naturalistic child speech (CS) and child-directed speech (CDS), we assessed the degree to which the frequency distribution of CDS predicted CS usage over time, and systematically identified CS that was over- or underrepresented in the corpus with respect to matched CDS baselines. Results showed that CDS explained 61% of the variance in CS single-word use and 19.3% of the variance in two-word combinations. Furthermore, the bilingual nature of the over or -underrepresented CS was partially attributable to factors beyond the corpus statistics, namely individual differences between children in their bilingual learning environment. In two out of the three children, overrepresented two-word combinations contained higher levels of syntactic slot redundancy than underrepresented CS. These results are discussed with respect to the role that redundancy plays in producing semiformulaic slot-and-frame patterns in CS.
Lie detection research comparing manual and automated coding of linguistic cues is limited. In Experiment 1, we attempted to extend this line of research by directly comparing the veracity differences in manual coding and two coding software programs (Text Inspector and Linguistic Inquiry and Word Count [LIWC]) on the linguistic cue “total details” across eight published datasets. Mixed model analyses revealed that LIWC showed larger veracity differences in total details than Text Inspector and manual coding. Follow-up classification analyses showed that both automated coding and manual coding could accurately classify honest and false accounts. In Experiment 2, we examined if LIWC’s sensitivity to veracity differences was the result of honest accounts including more redundant (repeated) words than false accounts as LIWC—but not Text Inspector or manual coding—accounts for redundancy. Our prediction was supported, and the most redundant words were function words. The results implicated that automated coding can detect veracity differences in total details and redundancy, but it is not necessarily better than manual coding at accurately classifying honest and false accounts.
Text comprehension and picture comprehension can be synthesized into a common conceptual framework which differentiates between external and internal descriptive and depictive representations. Combining this framework with the human cognitive architecture including sensory registers, working memory, and long-term memory leads to an integrated model of text and picture comprehension. The model consists of a descriptive branch and a depictive branch of processing. It includes multiple sensory modalities. Due to a flexible combination of sensory modalities and representational formats, the model covers listening comprehension, reading comprehension, visual picture comprehension, and sound comprehension. The model considers text comprehension and picture comprehension to be different routes for constructing mental models and propositional representations with the help of prior knowledge. It allows us to explain the effects of coherence, text modality, split attention, text–picture contiguity, redundancy, sequencing, and the effects of different types of visualization.
This chapter completes our critical exploration of Popper’s key work, the Logic of Scientific Discovery and how it applies to corpus linguistics. In this chapter we address the question of how easily linguistics may be viewed as a science, in Popper’s terms. We also consider important critiques of Popper’s work and use those to both clarify and, where necessary, adapt the framework.
Sensor placement optimization (SPO) is usually applied during the structural health monitoring sensor system design process to collect effective data. However, the failure of a sensor may significantly affect the expected performance of the entire system. Therefore, it is necessary to study the optimal sensor placement considering the possibility of sensor failure. In this article, the research focusses on an SPO giving a fail-safe sensor distribution, whose sub-distributions still have good performance. The performance of the fail-safe sensor distribution with multiple sensors placed in the same position will also be studied. The adopted data sets include the mode shapes and corresponding labels of structural states from a series of tests on a glider wing. A genetic algorithm is used to search for sensor deployments, and the partial results are validated by an exhaustive search. Two types of optimization objectives are investigated, one for modal identification and the other for damage identification. The results show that the proposed fail-safe sensor optimization method is beneficial for balancing the system performance before and after sensor failure.
Building up from first principles and simple scenarios, this comprehensive introduction to rigid body dynamics gradually introduces readers to tools to address involved real-world problems, and cutting-edge research topics. Using a unique blend of conceptual, theoretical and practical approaches, concepts are developed and rigorously applied to practical examples in a consistent and understandable way. It includes discussion of real-world applications including robotics and vehicle dynamics, and over 40 thought-provoking fully worked examples to cement readers' understanding. Providing a wealth of resources allowing readers to confidently self-assess – including over 100 problems with solutions, over 400 high quality multiple choice questions, and end-of-chapter puzzles dealing with everyday situations – this is an ideal companion for undergraduate students in aerospace, civil and mechanical engineering.
The SVCs have a cluster of grammatical traits not derivable exclusively from UG, some of which have been misrepresented/misunderstood in the UG literature. The first functional void of UG is proposed which limits the lexicalization of a semantic relation R to only those cases where R connects first-order entities. All the characteristic properties of SVCs result from this functional void collaborating with the proposed Serial Verb Parameter (SVP) in the theory of the UG–iconicity interface. It also explains a wide range of related cross-linguistic facts, from phrasal SVCs to compounds, the parametric variations between Chinese and Gbe languages in (dis)allowing ditransitive V1, why the resultative SVC acts in a particular set of ways different from other types and the subtle disparities between head-initial and head-final SVCs, as well as the full range of variations among Kwa languages in object- and verb-fronting. The relation between the linearization pattern of UG and the iconicity-induced word order of SVCs is shown to pattern with the “high” and “low” neural pathways underlying fear, with implications on the nature of redundancy in biologically based systems and suggestive of an evolutionary connection between these two linearization mechanisms in language.
Synthesising different collapse mechanisms for indeterminate beams and frames is considered via the prospect of their salient bending moments (without solving for their exact values) as candidate positions for the formation of plastic hinges. The method of Instantaneous Centre is introduced for calculating the relative motion of sub-structures within frames, including those with pitched roofs under distributed loading.
Maxwell's Rule conveys a statement of rigidity for a given truss framework. When the number of bars or supports is reduced, the truss will inevitably lose rigidity and collapse as a mechanism. This consequence can also be captured by Maxwell's Rule in a modified statement, which leads to a discussion about its interplay with states of self-stress, illustrated using the simplest pin-jointed arch.
We suggest (Proposition 5) that a community is functionally assembled when there is at least one species representing each functional type that is adapted to the habitat. We suggest (Proposition 6) that a community is fully assembled when each functional type has the maximum number of species that can coexist. Much biological diversity lies in the lower tail of the log-normal distribution, yet ecologists frequently trim this tail of rare species to construct models. The rising tide of species extinctions requires us to revisit this procedure, and to consider how to include conservation of rare species in models for community assembly. This requires us to recognize that there are two types of “rare” species in ecological data sets: those that are merely rare in samples and those that are designated as globally rare and at risk of extinction. Most communities arise from pre-existing communities, so when filters change there is often inertia in community response, and this inertia is related to traits. The principles laid out in this book provide a guide not only to theoretical understanding but for the challenges of ecological restoration.
A sequence
$\left \{g_k\right \}_{k=1}^{\infty }$
in a Hilbert space
${\cal H}$
has the expansion property if each
$f\in \overline {\text {span}} \left \{g_k\right \}_{k=1}^{\infty }$
has a representation
$f=\sum _{k=1}^{\infty } c_k g_k$
for some scalar coefficients
$c_k.$
In this paper, we analyze the question whether there exist small norm-perturbations of
$\left \{g_k\right \}_{k=1}^{\infty }$
which allow to represent all
$f\in {\cal H};$
the answer turns out to be yes for frame sequences and Riesz sequences, but no for general basic sequences. The insight gained from the analysis is used to address a somewhat dual question, namely, whether it is possible to remove redundancy from a sequence with the expansion property via small norm-perturbations; we prove that the answer is yes for frames
$\left \{g_k\right \}_{k=1}^{\infty }$
such that
$g_k\to 0$
as
$k\to \infty ,$
as well as for frames with finite excess. This particular question is motivated by recent progress in dynamical sampling.
We give a short introduction to some classical information-theoretic quantities: joint entropy, conditional entropy and mutual information. We then interpret their exponentials ecologically, as meaningful measures of subcommunities of a larger metacommunity. These subcommunity and metacommunity measures have excellent logical properties, as we establish. We also show how all these quantities can be presented in terms of relative entropy and the value measures of the previous chapter.
In this article, we improve the efficiency of a turbine blade inspection robotic workcell. The workcell consists of a stationary camera and a 6-axis serial robot that is holding a blade and presenting different zones of the blade to the camera for inspection. The problem at hand consists of a 6-DOF (degree of freedom) continuous optimization of the camera placement and a discrete combinatorial optimization of the sequence of inspection poses (images). For each image, all robot configurations (up to eight) are taken into consideration. A novel combined approach is introduced, called blind dynamic particle swarm optimization (BD-PSO), to simultaneously obtain the optimal design for both domains. The objective is to minimize the cycle time of the inspection process, while avoiding any collisions. Even though PSO is vastly used in engineering problems, the novelty of our combinatorial optimization method is in its ability to be used efficiently in traveling salesman problems where the distances between the cities are unknown and subject to change. This highly unpredictable environment is the case of the inspection cell where the cycle time between two images will change for different camera placements.
Chapter 9 builds on the concepts of effect traits to provide a tool for connecting biodiversity effects to multiple ecosystem processes and services, through species traits. First, an overview of the multiple effects of different traits, and organism types, on different ecosystem processes is provided. Then, two main hypotheses are proposed to explain how traits influence ecosystem processes: the mass ratio hypothesis (the dominant trait in the community, mainly associated to CWM) and the complementarity hypothesis (the variation in trait values in the community, mainly associated to FD). A detailed discussion is provided on how to disentangle the roles of CWM and FD in affecting ecosystem functions, for which specifically designed experiments are often needed (particularly to tease apart the mathematical non-independence between CWM and FD). These tools are further discussed in the light of classical approaches decomposing biodiversity effects into different components (net diversity effect, selection effect and niche complementarity).
Chapter 5 provides concepts and tools to characterize the functional trait structure of communities. Various indices are introduced, mainly community weighted mean (CWM) and various functional diversity (FD) indices. The power and the limitations of CWM are discussed. Various indices of FD, which expresses the extent of trait differences between organisms, are introduced to simplify their use and interpretation. The broad classification into ‘families’ of indices, i.e. functional richness, functional evenness and functional divergence, is discussed. A selection of indices, with their ability to provide a measure of FD at different scales (alpha, beta and gamma diversity), is discussed, together with other emerging components such as functional redundancy and functional rarity. A discussion on existing R tools, with their potential tricks and problems, is provided, also with examples available in the R material accompanying this chapter.
In this chapter we attempt to separate the communal and the individual levels of language representation and explore how linguistic regularities emerge at each of them. We sample one communal and ten individual corpora of language use from the same ELF environment and examine to what extent syntactic structure, priming and chunking influence linguistic choice in each corpus by looking at the variation between contracted and full forms (it is/it’s). We find clear differences in how these three factors work across the corpora and attempt to interpret them in relation to the properties of individual languages, language change and the role of ELF.
People often attribute rumours to an individual in a knowledgeable position two steps removed from them (a credible friend of a friend), such as ‘my friend's father, who's a cop, told me about a serial killer in town’. Little is known about the influence of such attributions on rumour propagation, or how they are maintained when the rumour is transmitted. In four studies (N = 1824) participants exposed to a rumour and asked to transmit it overwhelmingly attributed it either to a credible friend of a friend, or to a generic friend (e.g. ‘a friend told me about a serial killer in town’). In both cases, participants engaged in source shortening: e.g. when told by a friend that ‘a friend told me …’ they shared the rumour as coming from ‘a friend’ instead of ‘a friend of friend’. Source shortening and reliance on credible sources boosted rumour propagation by increasing the rumours’ perceived plausibility and participants’ willingness to share them. Models show that, in linear transmission chains, the generic friend attribution dominates, but that allowing each individual to be exposed to the rumour from several sources enables the maintenance of the credible friend of a friend attribution.
The expansion in subject matter of copyright, design and trade marks has made cumulation of protection a more common occurrence, even if the problem has long been recognised as a challenge for intellectual property law. EU law has no consistent approach to overlapping subject matter. In some cases, cumulation is permitted (and perhaps even mandatory). In others, it is looked upon with disfavour. However, it is clear that when regimes clash and cumulation rejected, trade mark law appears the one most likely to be regarded as pre-empted. This chapter considers reasons why this might be so, and finds most possible reasons wanting. However, this analysis does offer some important insights into the nature and challenges of trade mark law in Europe.
