Pretest Exposure

The present research investigates the effects of top-down information on 12-month-olds’ representations of physical events, focusing on their ability to detect an object change across different events. Infants this age typically fail to detect height changes in events with tubes even though they successfully do so in events with covers. In Experiment  1, infants who saw a tube event in which objects did not interact successfully detected a change in an object’s height, suggesting that object interaction affects infants’ categorization of physical events. Experiments 2 and 3 examined the fine-grained process of event representation. In Experiment  2, infants detected the change in the tube event if they were led by pretest exposure to believe that the event was conducted with a cover. In Experiment  3, infants who initially believed so updated their representation if shown a tube before object interaction occurred (but not after). Together, these findings provide new evidence that infants, like older children and adults, actively construct physical events. Whether they notice a change depends on their existing knowledge and the current representation of the event.

General Capacity

Mental time travel (MTT) is defined as projecting the self into the past and the future. Despite growing evidence of the similarities of remembering past and imagining future events, dominant theories conceive of these as distinct capacities. I propose that memory and imagination are fundamentally the same process – constructive episodic simulation – and demonstrate that the ‘simulation system’ meets the three criteria of a neurocognitive system. Irrespective of whether one is remembering or imagining, the simulation system: (1) acts on the same information, drawing on elements of experience ranging from fine-grained perceptual details to coarser-grained conceptual information and schemas about the world; (2) is governed by the same rules of operation, including associative processes that facilitate construction of a schematic scaffold, the event representation itself, and the dynamic interplay between the two (cf. predictive coding); and (3) is subserved by the same brain system. I also propose that by forming associations between schemas, the simulation system constructs multi-dimensional cognitive spaces, within which any given simulation is mapped by the hippocampus. Finally, I suggest that simulation is a general capacity that underpins other domains of cognition, such as the perception of ongoing experience. This proposal has some important implications for the construct of ‘MTT’, suggesting that ‘time’ and ‘travel’ may not be defining, or even essential, features. Rather, it is the ‘mental’ rendering of experience that is the most fundamental function of this simulation system, enabling humans to re-experience the past, pre-experience the future, and also comprehend the complexities of the present.

Learning Techniques

Fine-grained change detection in sensor data is very challenging for artificial intelligence though it is critically important in practice. It is the process of identifying differences in the state of an object or phenomenon where the differences are class-specific and are difficult to generalise. As a result, many recent technologies that leverage big data and deep learning struggle with this task. This review focuses on the state-of-the-art methods, applications, and challenges of representation learning for fine-grained change detection. Our research focuses on methods of harnessing the latent metric space of representation learning techniques as an interim output for hybrid human-machine intelligence. We review methods for transforming and projecting embedding space such that significant changes can be communicated more effectively and a more comprehensive interpretation of underlying relationships in sensor data is facilitated. We conduct this research in our work towards developing a method for aligning the axes of latent embedding space with meaningful real-world metrics so that the reasoning behind the detection of change in relation to past observations may be revealed and adjusted. This is an important topic in many fields concerned with producing more meaningful and explainable outputs from deep learning and also for providing means for knowledge injection and model calibration in order to maintain user confidence.

AbstractLeading accounts of tort law split cleanly into two seams. Some trace its foundations to a deontic form of morality; others to an instrumental, policy-oriented system of efficient loss allocation. An increasingly prominent alternative to both seams, Civil Recourse Theory (CRT) resists this binary by arguing that tort comprises a basic legal category, and that its directives constitute reasons for action with robust normative force. Using the familiar question whether tort’s directives are guidance rules or liability rules as a lens, or prism, this essay shows how considerations of practical reasoning undermine one of CRT’s core commitments. If tort directives exert robust normative force, we must account for its grounds—for where it comes from, and why it obtains. CRT tries to do so by co-opting H.L.A. Hart’s notion of the internal point of view, but this leveraging strategy cannot succeed: while the internal point of view sees legal directives as guides to action, tort law merely demands conformity. To be guided by a directive is to comply with it, not conform to it, so tort’s structure blocks the shortcut to normativity CRT attempts to navigate. Given the fine-grained distinctions the theory makes, and with the connection between its claims and tort’s requirements thus severed, CRT faces a dilemma: it’s either unresponsive to tort’s normative grounds, or it’s inattentive to tort’s extensional structure.

AbstractSince the early 1990s, China has come a long way in legislating the foundational rules for its reformed economy. Virtually all of the important areas – contracts, business organizations, securities, bankruptcy and secured transactions, to name a few – are now covered by national legislation as well as lower-level regulations. Yet an important feature of a legal structure suited to a market economy is missing: the ability of the system to generate from below solutions to problems not adequately dealt with by existing legislation. The top-down model that has dominated Chinese law reform efforts to date can only do so much. What is needed now is a more welcoming attitude to market-generated solutions to the gaps and other problems that will invariably exist in legislation. The state's distrust of civil-society institutions and other bottom-up initiatives suggests, however, that this different approach will not come easily.

In this contribution a number of procedural issues related to the sentencing of child offenders and emanating from the Child Justice Act 75 of 2008 are considered in some detail. As a general rule, the Act requires pre-sentence reports to be obtained from probation officers before sentencing any child offender, with only a limited number of exceptions. The article argues that the peremptory nature of the Act means that a probation report is always required, even if reports by other experts are also available. The exceptions are limited to instances other than those where the child offender is sentenced to any form of imprisonment or to residence in a care centre. The article addresses the question of whether or not the reference to imprisonment includes alternative imprisonment which is imposed only as an alternative to a fine. It suggests that alternative imprisonment should, generally, not be imposed on child offenders. When an exception is not prevented because of the sentence, a pre-sentence report may be dispensed with only when the offence is a schedule-1 offence (the least serious class of offences) or when obtaining a report would prejudice the child. It is argued that these exceptions are likely to occur rather rarely. A final aspect of the Act’s provisions on pre-sentence reports is the requirement that reasons be given for a departure from the recommendations in a pre-sentence report. This requirement merely confirms the status quo. The Act permits the prosecutor to provide the court with a victim impact statement. Such a statement is defined in the Act. It is a sworn statement by a victim or someone authorised by the victim explaining the consequences to the victim of the commission of the crime. The article also addresses the issue of whether or not the child justice court might mero motu obtain a victim impact statement when the prosecution does not do so. Finally, the article addresses appeals against and reviews of the trial courts’ sentences. It notes that appeal by the child offender is made somewhat easier, as some child offenders need not obtain leave to appeal. These include children under the age of 16, or older children sentenced to imprisonment. Again, the meaning of “imprisonment” is at least somewhat ambiguous. The provisions on automatic review have attracted considerable judicial attention already. The majority of these judgments confirmed the apparently clear wording of the Act, in terms of which the cases of all child offenders under the age of 16 should be reviewed regardless of whether they were legally represented or of the sentence imposed. In the case of child offenders aged 16 or 17, only custodial sentences are reviewable. The judgments which found this to be an incorrect interpretation are dealt with in some detail, with the conclusion that they were incorrectly decided.

The City

As urban renewal agendas are fortified in cities globally, ‘creativity’ – as contained within discourses of the creative industries, the Creative City and the creative economy – is circulated as the currency of secure post-industrial urban futures. Using the nexus between creativity and the urban as a starting point, the authors investigate how local enterprises visually communicate the urban in a neighbourhood that is characterized by the interface between manufacturing and creative industries. This research takes a fine-grained approach to the notion of creativity through an audit and qualitative analysis of the visual presentation, material attributes and semiotic meaning of street numbers. The authors do this by collecting data on and analysing how street numbers have been made, selected, used, replaced and layered in a contested industrial precinct in Australia’s largest city, Sydney. They contend that street numbers, as a ubiquitous technology within the city that is both operational and creative, are metonyms for what they understand to be urban. In arguing for vernacular readings of the city, they make use of a top-down, governmental mode of reading the city – the operational legibility of street numbering – as an intervention in current discourses of the urban and of creativity in the city.

Abstract The winner–loser electoral status may affect citizens’ perceptions of the national economy. In the context of Europe, this issue has aroused little interest as multi-party competition makes it difficult to study. We look at the 2016 Italian constitutional referendum, a top-down national referendum, which approximates second-order elections and divides voters in two groups, allowing the study of the effects of elections on opinions. Using a pre-post referendum panel survey, results show that losers—relying on motivated reasoning—radically change their retrospective and prospective economic evaluations after the referendum, and that this effect is conditional on party identification. The article provides new evidence on the role of partisan loyalties in the adjustment of economic perceptions.

In this study, we build on the foundational observations of Selznick and Stinchcombe that organizations bear the lasting imprint of their founding context and explore how characteristics shaped during founding are coherently carried forward through time. To do so, we draw on an ethnography of a social venture where the entrepreneurs left soon after founding. In examining how an initial organizational imprint evolves beyond a venture’s founding phase, we focus on the actions and interactions of organizational members, the founders’ imprint, the venture’s new leadership, and the external environment. The process model we develop shows how the organizational imprint evolves as a consequence of the interplay between top-down and bottom-up forces. We first find that the initial imprint is transmitted through a bottom-up mechanism of imprint reinforcement, and second, that the venture is reimprinted after the founding period through two processes which we call imprint reforming and imprint coupling. The result of this is the formation of a sedimented imprint. Our findings further illuminate that, although the initial imprint sticks, its function and manifestation changes over time.

Purpose This study aims to examine the clear speaking strategies used by older children when interacting with a peer with hearing loss, focusing on both acoustic and linguistic adaptations in speech. Method The Grid task, a problem-solving task developed to elicit spontaneous interactive speech, was used to obtain a range of global acoustic and linguistic measures. Eighteen 9- to 14-year-old children with normal hearing (NH) performed the task in pairs, once with a friend with NH and once with a friend with a hearing impairment (HI). Results In HI-directed speech, children increased their fundamental frequency range and midfrequency intensity, decreased the number of words per phrase, and expanded their vowel space area by increasing F1 and F2 range, relative to NH-directed speech. However, participants did not appear to make changes to their articulation rate, the lexical frequency of content words, or lexical diversity when talking to their friend with HI compared with their friend with NH. Conclusions Older children show evidence of listener-oriented adaptations to their speech production; although their speech production systems are still developing, they are able to make speech adaptations to benefit the needs of a peer with HI, even without being given a specific instruction to do so.
