This chapter explains how to design experiments that make AI claims credible. It begins with framing clear experimental questions, then shows how to choose evaluation tasks that actually test the core difficulty your work targets. It discusses selecting baselines and metrics that make comparisons meaningful and exposes trade-offs rather than hiding them. The chapter emphasizes careful analysis of stochastic results, including variability across runs, and warns about pitfalls such as overfitting to benchmarks or rewriting the story after seeing outcomes. Evaluation is presented as an iterative cycle that also generates new ideas.
Creativity in design is assessed based on novelty and value. Existing methods to assess novelty, value and creativity (NVC) in design primarily focus on ideas/concepts. The objectives of this research are as follows: (a) to develop a method to assess novelty and value of prototypes and, from these, calculate their creativity; (b) to demonstrate the use of the method and (c) to evaluate the method’s precision, reliability and effectiveness. The method uses metrics and evaluation aspects pertinent to a given prototype, and these are extracted from requirements in a design task. The method is demonstrated by using it to assess NVC of functional prototypes developed in a course project. The method’s precision is evaluated in terms of variance in NVC values when used to assess a given functional prototype; the coefficient of variation ranges between 0.22 and 0.44. The reliability is evaluated by comparing NVC values of a prototype obtained through the method with those estimated by experienced designers; the normalized RMSE varies between 7% and 16%. The effectiveness is evaluated by comparing NVC values of a prototype assessed with/by: the proposed method, an existing method and experienced designers. The proposed method shows more alignment with experts’ intuitive evaluation compared to the existing method.
This chapter provides a brief account of the languages of early Ireland from the earliest attested forms of Ogham (5th century), Old Irish, and Latin (both 7th century) through developments in the eleventh and early twelfth centuries
Vedic meter, being quantitative, is generally assumed to ignore the language’s lexically distinctive pitch accent. Nevertheless, beyond the obvious absence of any strict requirements, possible preferential interactions between meter and accent have remained unexplored. This article presents a series of word shape- and category-controlled tests, all of which support the conventional wisdom: accent plays no systematic role in meter. (While I do discover an effect of tonal NonFinality, it is not confined to meter.) Moreover, beyond meter, I find no support for other possible roles of accent in poetry, such as responsion, formularity, clash, lapse, or strictness modulation. This work bears on poetic typology (specifically, how prosodic features interact in metrics), on the realization of the Vedic accent as tone vs. stress-and-tone, and on (mixed model and Monte Carlo) methodologies for corpus prosody.
We propose a new approach to metrics based on maxent grammars, which employ weighted constraints and assign well-formedness values to verse lines. Our approach provides an account of metricality and complexity that has a principled mathematical basis and integrates information from all aspects of scansion. Our approach also makes it possible to detect vacuous constraints through statistical evaluation.
We begin with a system built on earlier work that defines the set of possible constraints, following principles of stress matching, bracket matching, and contextual salience. The basic concepts of this system work well in describing our data corpora, taken from Shakespeare’s Sonnets and Milton’s Paradise Lost. However, one well-known type of constraint, based on the principle of the stress maximum (Halle & Keyser 1966 et seq.), emerges as vacuous; testing indicates that the work of such constraints is already done by simpler constraints independently needed in the grammar.
This article explores the relationship between linguistic tone and musical melody in Tommo So, a Dogon language of Mali. Most fundamentally, contrary mappings (rising tone on falling music, or vice versa) are strongly penalized, while oblique mappings (flat tone on changing music, or vice versa) are largely tolerated. Strictness of mapping is further modulated by several factors, including whether the tones straddle a word boundary, whether their source is lexical or grammatical, what the position is in the line, and so forth. We model these conditions using weighted, stringent constraints and conclude that tone-tune setting bears more in common with metrics than previously recognized, setting the groundwork for a more general theory of phonological mapping across modalities.
While some accounts of syllable weight deny a role for onsets, onset-sensitive weight criteria have received renewed attention in recent years (e.g. Gordon 2005, Topintzi 2010). This article presents new evidence supporting onsets as factors in weight. First, in complex stress systems such as those of English and Russian, onset length is a significant attractor of stress both in the lexicon and in nonce probes. This effect is highly systematic and unlikely, it is argued, to be driven by analogy alone. Second, in flexible quantitative meters (e.g. in Sanskrit), poets preferentially align longer onsets with heavier metrical positions, all else being equal. A theory of syllable weight is proposed in which the domain of weight begins not with the rime but with the p-center (perceptual center) of the syllable, which is perturbed by properties of the onset. While onset effects are apparently universal in gradient weight systems, they are weak enough to be usually eclipsed by the structure of the rime under categorization. This proposal therefore motivates both the existence of onset weight effects and the subordination of the onset to the rime with respect to weight.
Clinical and Translational Science Award (CTSA) hubs are charged with supporting high-quality, community-engaged clinical research; improving the effectiveness and efficiency of research; and facilitating dissemination and implementation of findings into practice, leading to improved clinical outcomes and public health. Traditional academic outcomes, such as publications, subsequent grant funding, and innovative research methods, have often been cited as evidence of hubs’ impacts. This article describes one CTSA’s approach to extending beyond traditional research outcomes to operationalizing and measuring impacts on health, health care, and public support of research. The approach replaces logic models with key driver diagrams, shifts responsibility for performance indicators to individual programs, consolidates and standardizes impact measures across programs, and adapts existing measures, such as the Translational Science Benefits Model. Measurement challenges include the extended time from supporting a study to its impact, reliance on investigators and partners to provide information, gaining access to organization-wide data, limited validated tools for this purpose, and the limits to documenting breadth of impact. Early lessons learned include the need to embrace various and often imperfect methods and measures, strategically engage partners for mutual benefit, support programs to adopt a continuous improvement mindset, and collaborate with leadership to prioritize and support change.
The objective of this research is to identify and synthesize metrics to assess virtual prototypes in product design. The metrics are identified from literature and practitioners (novice/experienced designers and design faculty members), and evaluation categories are constituted. The identified metrics and constituted evaluation categories from: (a) literature and practitioners, and (b) across various practitioner groups, are compared. 144 and 29 distinct metrics are identified from literature and practitioners, resulting in 15 and 9 evaluations categories, respectively. The metrics from the practitioners is a subset of the metrics from the literature. The differences between: (a) literature and practitioners, and (b) across various practitioner groups, suggest the need for support to help practitioners choose relevant metrics for their prototyping context from an encompassing list.
Indicators of environmental impact can be used to inform the production, promotion and consumption of sustainable diets. Most environmental impacts associated with food production occur on farm; thus, sustainable diets are reliant on sustainable agricultural practices. In this paper, we review the current use of environmental indicators and metrics from global to local scales and highlight the need for locally relevant definitions to inform sustainable diets. Using Australia as a case study, we show that the diversity of food production systems is accompanied by a diversity of environmental issues, including climate change, land scarcity, nutrient pollution, water scarcity and biodiversity loss, each uniquely affecting different systems. However, while global datasets and indicators provide a consistent basis for estimating impacts and enabling country and food product comparisons, they often fail to capture the nuances of food production at national and sub-national scales. For example, land use may be a poor indicator of biodiversity loss when grazing a natural, low-input rangeland. Similarly, water use is only relevant where there is competition for the resource and eutrophication only where there is an adjacent water system to pollute. Thus, reporting frameworks used to inform sustainable diets need to be based on indicators that consider the context of local systems to demonstrate the clear linkage and how specific farming systems can drive sustainable diets. The development of provenance and traceability systems means the tools are already available to track impacts at a regional, or even individual farm, level.
In celebrating the 10th anniversary of BJPsych Open, this editorial review serves as a personal reflection and an overview of the birth, growth, expansion and excellence of the Journal as well as an introduction to the BJPsych Open 10th Anniversary Thematic Series. Specific emphasis is placed on changes and advances in productivity, the editorial board, publishing, thematic series, topical articles and focus on ethics. Further, articles of importance to our stakeholders are noted (top cited/downloaded, highlighted articles, articles of the month). The remit and vision for BJPsych Open remains unchanged: a general psychiatric journal with high-quality, methodologically rigorous and relevant publications, with relevance to the advancement of clinical care, patient outcomes, the scientific literature, research and policy. The Journal’s continued quality, growth and international recognition speak to its place in scientific literature, to the RCPsych mission to disseminate knowledge and to its bright future. As Editor-in-Chief, I note the debt of gratitude owed to an exemplary multidisciplinary team and the honour and privilege of serving in this role.
Over the last two decades, there have been significant investments designed to advance clinical and translational research (CTR) with an emphasis on supporting early career investigators and building a cadre of skilled researchers. Despite the investments, there are no comprehensive measurement tools to track individual-level progress along the research continuum as supports are put in place.
Objective:
The Researcher Investment Tool (RIT) is a novel tool that was created to provide a consistent approach for measuring individual-level changes in the research career trajectory of investigators receiving support from CTR programs.
Methods:
The RIT is a 90-item questionnaire, with eight domains and four sub-domains, designed to measure a researcher’s experiences and perceptions. Several rounds of testing were conducted to assess the tool’s face and content validity as well as the internal consistency and test-retest reliability.
Results:
Psychometric testing revealed strong content validity and good internal consistency with Cronbach’s alpha coefficients ranging from 0.85 to 0.97 across all domains. Test-retest reliability results also revealed stability in the domain measures over time with Pearson’s correlation coefficients ranging from 0.70 to 0.98 for all but one domain (.53).
Conclusions:
This novel RIT may be useful to evaluators when measuring the impact of investments designed to support early career clinical and translational researchers.
The components of a continuous quality improvement (CQI) program, a database, documentation, metrics, benchmarks, protocols, pathways, and standardized order sets are discussed.
The determinants of door-in-door-out metrics (DIDO) at centers referring acute ischemic stroke patients for endovascular thrombectomy (EVT) and the impact of DIDO on functional outcomes are unclear. Our primary objective was to study the association between DIDO and 90-day functional outcomes. Our secondary objective was to investigate the associations between patient clinical and workflow characteristics and DIDO.
Methods:
We conducted a province-wide multicentric retrospective cohort study in Québec, Canada, of adults with acute ischemic stroke who were transferred from a primary stroke center (PSC) to a comprehensive stroke center for EVT between 2017 and 2020. DIDO was calculated as the time spent in the PSC emergency department. Our co-primary outcomes, assessed 90 days after stroke, were a favorable functional outcome (modified Rankin score of 0–2) and death. We estimated associations between DIDO and co-primary outcomes and between patient characteristics and DIDO using logistic mixed models.
Results:
Among 790 included patients, the mean age was 69 (+/–14) years, and 400 (51%) were female. The median DIDO was 102 (80–135) minutes. DIDO was not associated with 90-day favorable functional outcome (aOR: 1.00, 95% CI [0.99–1.00], p = 0.54) or death (aOR: 1.00, 95% CI [0.99–1.01], p = 0.69). Arrival at the PSC outside daytime hours (aOR: 3.28, 95% CI [1.26–8.51], p = 0.01) was significantly associated with DIDO ≥ 60 minutes.
Conclusions:
Although DIDO are long in Québec, they are not associated with 90-day functional outcomes or mortality among patients transferred for EVT. Further research is required to develop strategies to improve modifiable determinants of DIDO, including workflow outside of daytime hours.
Typology establishes three degrees of metrical strength. Foot-based theories designate the intermediate degree as that of unparsed syllables, i.e. syllables that are not part of a foot. However, this denotation of parsing mispredicts massively; moreover, there is no real reason why such unparsed syllables should be of intermediate prosodic strength (as opposed to the weakest or strongest). This paper presents an alternative account in Strict CV metrics (Ulfsbjorninn 2014, Faust & Ulfsbjorninn 2018). The correct three-way hierarchy follows from the basic operation of the theory, namely incorporation, whereby one nucleus becomes prominent by incorporating metrical significance from another nucleus. Examples come first from the more classical cases of Dutch and English and then from three test-cases provided by unrelated languages: St’át’imcets (Lillooet Salish), Burmese, and Tiberian Hebrew. No appeal is made to the notion of parsing.
The standard of living is a conceptual object of great concern to governments, social scientists, and the public. How people lived in the past is likewise of much interest to historians. There is wide (if not universal) agreement that a higher standard of living is preferable to a lower one. Congruence ends there, however, as what constitutes the appropriate measure of people’s well-being is subject to a wide range of parallel, overlapping, and sometimes even conflicting opinions. How to collect the evidence necessary to calculate whatever measure we settle on, from both the contemporary world and the historical record, is equally contested. Indeed, in the case of efforts to measure well-being in the past, the evidence we might want may not exist at all. The question is too important though to settle for narrow and often misleading metrics that capture material wealth alone. Measures of our lifespan, the expansion of our mental capabilities, and our ability to feel secure and to participate in our collective governance make essential contributions. Finally, we need measures that are sensitive to the requirements for shared human sociability in different historical contexts. The insights of historians and other observers of human societies will be essential to complement the theorizing of social scientists.
This chapter takes up a final source of constraint, specifically the norms of the profession and judging. The idea that unarticulated, and often inarticulable, shared understandings serve as a source of discipline and constraint has a long history. Among the labels for it are situation sense, craft values, professional norms, and tacit knowledge. For such norms to exert force, they must be shared, and the chapter explores ways in which the scope of shared professional understandings has diminished. The polarization present in our society has made its way into the profession. More broadly, our culture has developed in ways that privilege the tangible and quantifiable, which has led to a collective preference for metrics over more traditional forms of expertise.
Usage data on research outputs such as books and journals is well established in the scholarly community. Yet, as research impact is derived from a broader set of scholarly outputs, such as data, code, and multimedia, more holistic usage and impact metrics could inform national innovation and research policy. While usage data reporting standards, such as Project COUNTER, provide the basis for shared statistics reporting practice, mandated access to publicly funded research has increased the demand for impact metrics and analytics. In this context, stakeholders are exploring how to scaffold and strengthen shared infrastructure to better support the trusted, multistakeholder exchange of usage data across a variety of outputs. In April 2023, a workshop on Exploring National Infrastructure for Public Access and Impact Reporting supported by the United States (US) National Science Foundation (NSF) explored these issues. This paper contextualizes the resources shared and recommendations generated in the workshop.
What if formularity, meter, and Kunstsprache in Homer weren't abstract, mechanical systems that constrained the poet's freedom, but rather adaptive technologies that helped poets to sustain feats of great creativity? This book explores this hypothesis by reassessing the key formal features of Homer's poetic technique through the lenses of contemporary linguistics and the cognitive sciences, as well as by drawing some unexpected parallels from the contemporary world (from the dialects of English used in popular music, to the prosodic strategies employed in live sports commentary, to the neuroscience of jazz improvisation). Aimed at Classics students and specialists alike, this book provides thorough and accessible introductions to the main debates in Homeric poetics, along with new and thought-provoking ways of understanding Homeric creativity.
Mass gatherings are events where many people come together at a specific location for a specific purpose, such as concerts, sports events, or religious gatherings, within a certain period of time. In mass-gathering studies, many rates and ratios are used to assess the demand for medical resources. Understanding such metrics is crucial for effective planning and intervention efforts. Therefore, this systematic review aims to investigate the usage of rates and ratios reported in mass-gathering studies.
Methods:
In this systematic review, the PRISMA guidelines were followed. Articles published through December 2023 were searched on Web of Science, Scopus, Cochrane, and PubMed using the specified keywords. Subsequently, articles were screened based on titles, abstracts, and full texts to determine their eligibility for inclusion in the study. Finally, the articles that were related to the study’s aim were evaluated.
Results:
Out of 745 articles screened, 55 were deemed relevant for inclusion in the study. These included 45 original research articles, three special reports, three case presentations, two brief reports, one short paper, and one field report. A total of 15 metrics were identified, which were subsequently classified into three categories: assessment of population density, assessment of in-event health services, and assessment of out-of-event health services.
Conclusion:
The findings of this study revealed notable inconsistencies in the reporting of rates and ratios in mass-gathering studies. To address these inconsistencies and to standardize the information reported in mass-gathering studies, a Metrics and Essential Ratios for Gathering Events (MERGE) table was proposed. Future research should promote consistency in terminology and adopt standardized methods for presenting rates and ratios. This would not only enhance comparability but would also contribute to a more nuanced understanding of the dynamics associated with mass gatherings.
