Chapter 6 delves deeply into the subject of communications in groups. We discuss the factors that hamper effective communications. We also explore the effects that gender and more broadly, member diversity can have on the nature of our communications. We include a section on factors and techniques that improve the quality of member communication in a diverse society.
Now in its fourth edition, this textbook provides a chronological account of first language acquisition, showing how young children acquire language in their conversational interactions with adult speakers. It draws on diary records and experimental studies from leaders in the field to document different stages and different aspects of what children master. Successive chapters detail infants' and young children's progression from attending to adult faces, gaze, and hand motions, to their first attempts at communicating with gaze and gesture, then adding words and constructions. It comprehensively covers the acquisition of the core areas of language – phonetics and phonology, lexicon, grammar and sentence structure, and meaning – as well as how children acquire discourse and conversational skills. This edition includes new sections on how children build 'common ground' with adults and other children, individual differences in children's language development, how they collaborate with adults in constructing utterances, and how they qualify beliefs.
In an article in this issue of BJPsych Advances a courageous psychiatrist describes judicial criticism of his expert testimony in a case before the UK's Upper Tribunal (Immigration and Asylum Chamber). This commentary reflects on the value of criticism and feedback on expert witness work, contrasting the psychiatrist's positive response to the judge's words with the reaction of an expert witness in clinical negligence case, who rejected criticism of his evidence.
This chapter focuses on how governments, public organizations, and public sector employees and managers can be more innovative. In other words, the motivating question is: What are the drivers and conditions for innovations in the public sector? Conditions for innovation are also essential because public sector employees, employees’ work groups, public organizations, countries, and international and supranational organizations must innovate. Thus, an important question becomes how and why individuals, groups, organizations, countries, and international organizations achieve innovations. What are the conditions for innovation? Answering this question is vital because it explains how governments (at national, regional, state, and local levels), organizations, groups, and individuals can innovate when there are the right conditions. In other words, based on the context and actors’ involvement, public organizations may require different conditions to innovate. This chapter discusses drivers and conditions of innovations at the national, organizational, workgroup, and individual levels.
Using data from direct observations, experimental mesocosms, field experiments, and complex computer models, the IPCC has made a very strong case supporting the hypothesis that human behavior is leading to rapid and substantial climate change. One important anthropogenic effect is changes to the carbon cycle, primarily greater CO2 export into the atmosphere from industrial activity. In recent years, both oceans and terrestrial sources have taken up some of this excess CO2, but ocean uptake is particularly problematic, because it leads to acidification. There are many other important greenhouse gases that influence Earth’s surface temperatures, including methane, nitrous oxide, ozone, and a diverse group of halocarbons. Though less abundant, these gases have a much greater global warming potential than CO2, on a per molecule basis. Many effects of greenhouse gases on global climate are complex; for example, a particular halocarbon can increase and decrease surface temperatures via different mechanisms. There are many different types of climate models that use the movement of the atmosphere around Earth, and the interaction of the atmosphere with the oceans and with biological processes, to project future climate. Though there are quantitative differences between the projections of each model, these models all project a much warmer and wetter global climate over the next century, with northern latitudes experiencing the greatest impact of climate change.
This chapter looks at early interactions between parent and infant, from joint looking at faces, gaze following, and attention to hands and gestures, to later interactions where infants and adults readily capture each other’s attention. It examines the ways adults modify their speech to infants and young children, e.g., with short, grammatical utterances, formulaic routines, repetitions in variation sets, higher pitch, slower rate, and pausing at the ends of utterances. Adults adjust their speech to what their children understand and provide feedback on children’s errors, checking up to make sure they have understood them and so offering them a conventional way to say what they appear to intend. Adults establish joint attention and engage with infant and child activities, anchoring their conversational contributions to what is physically present and visible, and talking about the child’s current activities. And infants become adept at attracting adult attention and enlisting their help in different activities. In child-directed speech, adults focus on what is physically and conversationally present, and respond to the topics children introduce. They choose short, high-frequency words, with high neighborhood density, many with concrete referents present in the here and now. Conversational interactions provide the setting for acquisition.
Language use is a skill that requires exposure to language, feedback on usage, and practice. So children need exposure from expert speakers, feedback on the language being acquired, and on any errors children produce, and practice along the way. Languages differ, so the paths children follow within and across languages may vary, and some constructions may be harder to acquire in one language, easier in another. The goal is to learn to use language for communication. Language is essentially social, relying on common ground. Part I (Chapters 2-6) focusses on how adults talk with children; children’s analysis of the speech stream; their first production of words; and how they assign meanings to words. Part II (Chapters 7-11) focusses on children’s acquisition of structure: elaborations of information inside clauses, and combinations of clauses. They also rely on structure when coining new words. Part III (Chapters 12-14) looks at turn-taking, learning to be polite, persuasive, and informative, and how to tell stories. Children who hear two languages have two such systems to learn. Part IV (Chapters 15-16) summarizes evidence for biological specialization for language and considers how continuity and change are reflected in language processing.
How do children process language as they get older? Is there continuity in the functions assigned to specific structures? And what changes in their processing and their representations as they acquire more language? They appear to use bracketing (finding boundaries), reference (linking to meanings), and clustering (grouping units that belong together) as they analyze the speech stream and extract recurring units, word classes, and larger constructions. Comprehension precedes production. This allows children to monitor and repair production that doesn’t match the adult forms they have represented in memory. Children also track the frequency of types and tokens; they use types in setting up paradigms and identifying regular versus irregular forms. Amount of experience with language, (the diversity of settings) plus feedback and practice, also accounts for individual differences in the paths followed during acquisition. Ultimately, models of the process of acquisition need to incorporate all this to account for how acquisition takes place.
This chapter introduces structures and structural interconnections for LTI systems and then considers several examples of digital filters. Examples include moving average filters, difference operators, and ideal lowpass filters. It is then shown how to convert lowpass filters into other types, such as highpass, bandpass, and so on, by use of simple transformations. Phase distortion is explained, and linear-phase digital filters are introduced, which do not create phase distortion. The use of digital filters in noise removal (denoising) is also demonstrated for 1D signals and 2D images. The filtering of an image into low and high-frequency subbands is demonstrated, and the motivation for subband decomposition in audio and image compression is explained. Finally, it is shown that the convolution operation can be represented as a matrix vector multiplication, where the matrix has Toeplitz structure. The matrix representation also shows us how to undo a filtering operation through a process called deconvolution.
Learning is a process. It takes time and often involves a degree of challenge. But how do students know that their learning is progressing? How do they identify ways to improve their learning? How do educators know whether the strategies and activities that they are using are helping students? This is the role of assessment – it helps students and educators to gauge progress and identify opportunities for improvement.
In Chapters 5, 6 and 7 we explored how to use digital technologies in the learning and teaching of the three domains of knowledge. In this chapter, we will close the loop by focusing on assessment and how digital technologies can help. We will start by considering the important role of assessment in learning and teaching. Following this, we will explore how to capture evidence of learning, assess learning and provide feedback using digital technologies. The chapter will conclude by exploring how to store and analyse assessment data using digital technologies.
Historically, most intelligence theories include the personal intelligences that encompass apprehension of one’s own experience, the ability to understand and manage people, and insight into the states of other people. Intrapersonal intelligence enables an individual to cultivate self-awareness, which operates during transitions at three progressive levels. Self-knowledge is produced by reflective thinking and is the basis for growth and development. The capacity for self-assessment follows and evaluates strengths and weaknesses during a transition. This supports self-development, which turns awareness into action. Interpersonal intelligence enables an individual to empathize with others, manage relationships in mutually beneficial ways, give and receive feedback, and build collaborative relationships that develop and ultimately lead others. The personal intelligences are investigated through retrospective interviews with twenty-four elite performers in three domains (business, sports, and music) who successfully and repeatedly transitioned to higher positions within their field.
This paper explores the interplay of feedback principles in design and systems science. From their roots in engineering, biology, and economics, it investigates intersections between design, cybernetics and servomechanisms. The synthesis emphasizes the need for considering feedback in anticipating unintended consequences and proposes an integrative view reconciling fundamental assumptions from the different fields through simulation. This holistic approach underscores the pivotal role of feedback in understanding and addressing complex phenomena, such as rebound effects, in design science.
The Canadian League Against Epilepsy initiated a virtual epilepsy education program, conducting 29 webinars from March 2021 to September 2023. We report our experience, with the goal to inspire other groups to develop inclusive, equitable, and free educational spaces with a worldwide reach. Monthly sessions drew a median attendance of 118 participants, predominantly Canadian but also international, including physicians (58.9%) and trainees (22.8%). Post-webinar surveys (average 40% response rate) noted high satisfaction, a strong inclination to recommend the sessions, and an interest in clinical case-based topics. We plan to consider integrating a self-assessment section evaluating knowledge gained after each seminar.
In Chapter 10 we discuss feedback and control as an advanced topic. We introduce how to use the measurement results to control the quantum system, via applying conditional unitary operator. A number of experimental systems are discussed, including active qubit phase stabilization, adaptive phase measurements, and continuous quantum error correction.
While studies have shown the importance of listener feedback in dialogue, we still know little about the factors that impact its quality. Feedback can indicate either that the addressee is aligning with the speaker (i.e. ‘positive’ feedback) or that there is some communicative trouble (i.e. ‘negative’ feedback). This study provides an in-depth account of listener feedback in task-oriented dialogue (a director–matcher game), where positive and negative feedback is produced, thus expressing both alignment and misalignment. By manipulating the listener’s cognitive load through a secondary mental task, we measure the effect of divided attention on the quantity and quality of feedback. Our quantitative analysis shows that performance and feedback quantity remain stable across cognitive load conditions, but that the timing and novelty of feedback vary: turns are produced after longer pauses when attention is divided between two speech-focused tasks, and they are more economical (i.e. include more other-repetitions) when unrelated words need to be retained in memory. These findings confirm that cognitive load impacts the quality of listener feedback. Finally, we found that positive feedback is more often generic and shorter than negative feedback and that its proportion increases over time.
Chapter 3 presents a variety of feedback methods that practitioners and researchers alike use to support learners’ linguistic development. Building on the belief that errors are a normal and even beneficial part of language learning, this chapter shares how and why feedback is a critical component of language teaching. Examples of oral corrective feedback are provided, along with a description of when teachers may choose to use what type of feedback over another.
An important tool of the mind for analysing sustainability issues is systems thinking -- that is, interpreting observations in causal relationships between elements. I present some of the key features of system dynamics: stock-flow, feedbacks, inertia, delays, change processes, causal loop diagrams (CLDs) and archetypes. Systems modelling is an art: which problems are addressed, which elements and relationships are identified as relevant, which hypotheses about system behaviour are explored? Such acts of modelling tend to be worldview-biased by nature. The appearance of powerful IC-tools has broadened the domain of (formal) modelling. I present three novel approaches, with examples: Cellular Automat (CA), network analysis and agent-based modelling (ABM).
Cosmological simulations fail to reproduce realistic galaxy populations without energy injection from active galactic nuclei (AGN) into the interstellar medium (ISM) and circumgalactic medium (CGM); a process called ‘AGN feedback’. Consequently, observational work searches for evidence that luminous AGN impact their host galaxies. Here, we review some of this work. Multi-phase AGN outflows are common, some with potential for significant impact. Additionally, multiple feedback channels can be observed simultaneously; e.g., radio jets from ‘radio quiet’ quasars can inject turbulence on ISM scales, and displace CGM-scale molecular gas. However, caution must be taken comparing outflows to simulations (e.g., kinetic coupling efficiencies) to infer feedback potential, due to a lack of comparable predictions. Furthermore, some work claims limited evidence for feedback because AGN live in gas-rich, star-forming galaxies. However, simulations do not predict instantaneous, global impact on molecular gas or star formation. The impact is expected to be cumulative, over multiple episodes.
Limited data exist on how trainees in paediatric cardiology are assessed among countries affiliated with the Association of European Paediatric and Congenital Cardiology.
Methods:
A structured and approved questionnaire was circulated to educationalists/trainers in 95 Association for European Paediatric and Congenital Cardiology training centres.
Results:
Trainers from 46 centres responded with complete data in 41 centres. Instructional design included bedside teaching (41/41), didactic teaching (38/41), problem-based learning (28/41), cardiac catheterisation calculations (34/41), journal club (31/41), fellows presenting in the multidisciplinary meeting (41/41), fellows reporting on echocardiograms (34/41), clinical simulation (17/41), echocardiography simulation (10/41), and catheterisation simulation (3/41). Assessment included case-based discussion (n = 27), mini-clinical evaluation exercise (mini-CEX) (n = 12), directly observed procedures (n = 12), oral examination (n = 16), long cases (n = 11), written essay questions (n = 6), multiple choice questions (n = 5), and objective structured clinical examination (n = 2). Entrustable professional activities were utilised in 10 (24%) centres. Feedback was summative only in 17/41 (41%) centres, formative only in 12/41 (29%) centres and a combination of formative and summative feedback in 10/41 (24%) centres. Written feedback was provided in 10/41 (24%) centres. Verbal feedback was most common in 37/41 (90 %) centres.
Conclusion:
There is a marked variation in instructional design and assessment across European paediatric cardiac centres. A wide mix of assessment tools are used. Feedback is provided by the majority of centres, mostly verbal summative feedback. Adopting a programmatic assessment focusing on competency/capability using multiple assessment tools with regular formative multisource feedback may promote assessment for learning of paediatric cardiology trainees.
Drawing on my own background as an aspiring writer, I highlight the core difference between little-c (everyday creativity) and Big-C (genius) before talking about the creation (with Ron Beghetto) of the four Cs model of creativity. Mini-c is creativity that is personally meaningful to the creator, even if it does not resound with others. Indeed, there are many reasons why creative work may not reach an audience, which is the topic of the CASE (Capital Awareness Spark Exceptionality) model. How does mini-c advance to little-c? One key is getting, and responding to, good feedback and critiques of one’s work. Another is improving creative metacognition, which has two parts: understanding your own creative strengths and weaknesses and knowing when (or when not) to be creative.
