Over Time

This book examines how language works in democratic politics and how it impacts the effectiveness of policy. Using evidence from the first computer-assisted analysis of all 41.5 million words of legislation enacted from 1900 to 2015, it tracks the major changes in form and function that Parliament's use of language has undergone over time and the reasons for such changes. More importantly, it explores the policy and social implications of changes in legislative language as well as the issue of legislative indeterminacy. This introductory chapter discusses the questions, arguments and aims of the book and reviews the literature on the operation of language in British politics, along with the impact of legislative language on policy effectiveness. It also explains what specifically the book contributes to the existing literature, describes the research design, and provides an overview of the chapters that follow.

Insufficient Number

Users of Web search engines report two main problems: an insufficient number of relevant results and the mixing of relevant results with irrelevant results. Therefore, this research investigates the effects of query ambiguity and three forms of sorting search results on user performance and preference. Forty-eight Web search engine users evaluated three forms of sorting results. For each task, the query was a single term that had one, two, or three meanings. The results indicated that the preferred results sorting method was affected by the page number of the correct results. When the correct results were all located on the same page (i.e., the first page), the participants preferred the Ranking, Disambiguating, and Categories methods when the query term had one, two and three meanings, respectively. When the correct results were not on the first page, the test participants preferred the Categories sorting method for all number of query meanings.

ABSTRACTThe study characterizes developmental trends in early Hebrew clause-combining (CC) by analyzing the interplay between linguistic form and communicative function in different interactional settings. Analysis applied to all utterances produced by three children aged 2;0–3;0 who combined two or more clauses, either self-initiated or on the basis of adult input. Ten types of CC were analyzed for marking by connectives (e.g. the Hebrew equivalents of ‘and’, ‘that’, ‘so’). Four shared consecutive developmental phases emerged: non-marking; partial marking by ‘and’ and ‘that’; use of ‘but’ and ‘because’, favored significantly in interlocutor-supported contexts; marking of adverbial relations and more varied use ofše-‘that’. These CC processes are interpreted as reflecting general properties of language development, in the form of gradually increasing specification of form–function relations under the impact of interlocutor–child interactive support combined with Hebrew-particular typological factors.

<p>Skin injuries are a health problem and can lead to serious, significant deterioration in the quality of life and, consequently, even illness and disability. Therefore, after wounding, immediate regeneration of the tissue is necessary to avoid further complications and pathogenesis. Consequently, many wound healing strategies have been developed, leading to the progress in constructing of multifunctional tissue substitutes for the skin, biomembranes, scaffolds and intelligent dressings. The field of science focusing on the creation of the above-mentioned products is tissue engineering (TE). Its main goal is to find a system that is able to replace or be a model that perfectly mimics the form and function of the skin. Research carried out on such constructs is mainly based on the analysis of mechanical properties (porosity, elasticity), as well as the assessment of the impact of individual components on processes related to the formation of new tissue as cell proliferation and differentiation, proliferation, angiogenesis - through <em>in vivo</em> studies (using animal models: mice, New Zealand rabbits) and <em>in vitro</em> (most often using mouse fibroblasts - L929). Skin constructions may have potential applications as wound dressings or skin substitutes in cases of severe skin damage.</p>

This article discusses the Keyboard Augmentation Toolkit (KAT), which supports the creation of virtual keyboards that can be used both for standalone input (e.g., for mid-air text entry) and to augment physically tracked keyboards/surfaces in mixed reality. In a user study, we firstly examine the impact and pitfalls of visualising shortcuts on a tracked physical keyboard, exploring the utility of virtual per-keycap displays. Supported by this and other recent developments in XR keyboard research, we then describe the design, development, and evaluation-by-demonstration of KAT. KAT simplifies the creation of virtual keyboards (optionally bound to a tracked physical keyboard) that support enhanced display —2D/3D per-key content that conforms to the virtual key bounds; enhanced interactivity —supporting extensible per-key states such as tap, dwell, touch, swipe; flexible keyboard mappings that can encapsulate groups of interaction and display elements, e.g., enabling application-dependent interactions; and flexible layouts —allowing the virtual keyboard to merge with and augment a physical keyboard, or switch to an alternate layout (e.g., mid-air) based on need. Through these features, KAT will assist researchers in the prototyping, creation and replication of XR keyboard experiences, fundamentally altering the keyboard’s form and function.

ABSTRACT Microbes live in complex microniches within host tissues, but how symbiotic partners communicate to create such niches during development remains largely unexplored. Using confocal microscopy and symbiont genetics, we characterized the shaping of host microenvironments during light organ colonization of the squid Euprymna scolopes by the bacterium Vibrio fischeri. During embryogenesis, three pairs of invaginations form sequentially on the organ’s surface, producing pores that lead to interior compressed tubules at different stages of development. After hatching, these areas expand, allowing V. fischeri cells to enter and migrate ∼120 μm through three anatomically distinct regions before reaching blind-ended crypt spaces. A dynamic gatekeeper, or bottleneck, connects these crypts with the migration path. Once V. fischeri cells have entered the crypts, the bottlenecks narrow, and colonization by the symbiont population becomes spatially restricted. The actual timing of constriction and restriction varies with crypt maturity and with different V. fischeri strains. Subsequently, starting with the first dawn following colonization, the bottleneck controls a lifelong cycle of dawn-triggered expulsions of most of the symbionts into the environment and a subsequent regrowth in the crypts. Unlike other developmental phenotypes, bottleneck constriction is not induced by known microbe-associated molecular patterns (MAMPs) or by V. fischeri-produced bioluminescence, but it does require metabolically active symbionts. Further, while symbionts in the most mature crypts have a higher proportion of live cells and a greater likelihood of expulsion at dawn, they have a lower resistance to antibiotics. The overall dynamics of these distinct microenvironments reflect the complexity of the host-symbiont dialogue. IMPORTANCE The complexity, inaccessibility, and time scales of initial colonization of most animal microbiomes present challenges for the characterization of how the bacterial symbionts influence the form and function of tissues in the minutes to hours following the initial interaction of the partners. Here, we use the naturally occurring binary squid-vibrio association to explore this phenomenon. Imaging of the spatiotemporal landscape of this symbiosis during its onset provides a window into the impact of differences in both host-tissue maturation and symbiont strain phenotypes on the establishment of a dynamically stable symbiotic system. These data provide evidence that the symbionts shape the host-tissue landscape and that tissue maturation impacts the influence of strain-level differences on the daily rhythms of the symbiosis, the competitiveness for colonization, and antibiotic sensitivity.

Shield Design

This article seeks to elucidate the form and function of decorative designs on Nuaulu parrying shields from Seram, Indonesia. It builds on earlier work focusing on the shield as a sacred anthropomorphized entity with its own life-cycle, the reproduction of which mirrors the reproduction of sacred houses. It has previously been suggested that diversity in design elements is deliberately cultivated as part of a general aesthetic, connecting individuality, personhood and effervescence as features of living entities. Here the author examines the materiality of shields, documenting variation in design – especially patterns of ceramic and shell discs – and asks what significance should be attached to these. He concludes that the attribution of specific meanings to individual elements is of limited application, while the impact of the shields lies in variation itself, the perceptual affects shields have on viewers, and in abstract geometric characteristics that make them fit for ritual purpose.
