As in music, stress and accent in natural language are phenomenal prominences. A phenomenal prominence is always the most salient aspect of an acoustic contrast. A stress or accent might consist of a higher pitch, a greater amplitude, or a longer duration. It might also arise from differences in aspiration, vowel quality, or voicing. The primary purpose of stress and accent is to indicate a form’s temporal structure. It does this by indicating the positions of metrical prominences on the metrical grid. When phenomenal prominences correspond to metrical prominences, as they do in both music and language, they indicate the locations of metrical prominences and overall temporal organization. The key difference between metrical patterns in music and metrical patterns in language is that the former are typically more cyclic – or repetitive – than the latter with a more even distribution of prominences. Metrical organization is always rich and constructed automatically. Even when presented with a series of identical isochronous pulses, a hearer will automatically construct an analysis with multiple metrical levels. Stress and accent indicate which metrical analysis a listener should construct. This typically requires minimal information. A single accent per form can distinguish between the four perfect grid patterns, the simplest binary metrical patterns.
Chapter 9 summarizes the main points addressed in previous chapters. The main issues addressed in Chapter 1 are phenomenal prominence, metrical prominence, and the relationship between them. Chapter 2 addresses the Prosodic Hierarchy and structural prominence. Chapter 3 examines the typology of word stress. Chapter 4 examines two correspondence relationships: the relationship between prosodic categories and grid entries and the relationship between syntactic categories and prosodic categories. Directionality effects are addressed in Chapter 5, and grid well-formedness are addressed in Chapter 6. Chapter 7 examines boundary effects, and Chapter 8 focuses on feet.
Stress and accent are central to the study of sound systems in language. This book surveys key work carried out on stress and accent and provides a comprehensive conceptual foundation to the field. It offers an up-to-date set of tools to examine stress and accent from a range of perspectives within metrical stress theory, connecting the acoustic phenomenon to a representation of timing, and to groupings of individual speech sounds. To develop connections, it draws heavily on the results of research into the perception of musical meter and rhythm. It explores the theory by surveying the types of stress and accent patterns found among the world's languages, introducing the tools that the theory provides, and then showing how the tools can be deployed to analyse the patterns. It includes a full glossary and there are lists of further reading materials and discussion points at the end of each chapter.
Previous studies have shown that simply knowing one player moves first can affect behavior in games, even when the first-mover's moves are known to be unobservable. This observation violates the game-theoretic principle that timing of unobserved moves is irrelevant, but is consistent with virtual observability, a theory of how timing can matter without the ability to observe actions. However, this previous research only shows that timing matters in games where knowledge that one player moved first can help select that player's preferred equilibrium, presenting an alternative explanation to virtual observability. We extend this work by varying timing of unobservable moves in ultimatum bargaining games and “weak link” coordination games. In the latter, the equilibrium selection explanation does not predict any change in behavior due to timing differences. We find that timing without observability affects behavior in both games, but not substantially.
Chapter 5 focuses on the different temporalities that are interwoven in the station, feeding into everyday experiences and informing patterns of action. In Accra’s station, just as in most bus stations in Ghana, departures do not follow designated scripts dictated by clock time; instead, they are collectively timed by the inflow of passengers. These inflows follow different rhythmic temporalities co-composed in Accra and in the destinations served by the station. By detailing the daily work activities of an inexperienced and an experienced station worker, it teases out different levels of perceptual attunement to movement and rhythm taking shape hundreds of kilometres away. It argues that the tacit dimension of temporal and kinaesthetic enskilment highlights important qualities needed to make hustle successful, which essentially requires the ability to ‘read’ the different rhythms of eruptive situations and to align and time one’s actions accordingly.
Information on the time spent completing cognitive testing is often collected, but such data are not typically considered when quantifying cognition in large-scale community-based surveys. We sought to evaluate the added value of timing data over and above traditional cognitive scores for the measurement of cognition in older adults.
Method:
We used data from the Longitudinal Aging Study in India-Diagnostic Assessment of Dementia (LASI-DAD) study (N = 4,091), to assess the added value of timing data over and above traditional cognitive scores, using item-specific regression models for 36 cognitive test items. Models were adjusted for age, gender, interviewer, and item score.
Results:
Compared to Quintile 3 (median time), taking longer to complete specific items was associated (p < 0.05) with lower cognitive performance for 67% (Quintile 5) and 28% (Quintile 4) of items. Responding quickly (Quintile 1) was associated with higher cognitive performance for 25% of simpler items (e.g., orientation for year), but with lower cognitive functioning for 63% of items requiring higher-order processing (e.g., digit span test). Results were consistent in a range of different analyses adjusting for factors including education, hearing impairment, and language of administration and in models using splines rather than quintiles.
Conclusions:
Response times from cognitive testing may contain important information on cognition not captured in traditional scoring. Incorporation of this information has the potential to improve existing estimates of cognitive functioning.
Rhythm typology seeks to classify languages according to the units on which they base their rhythm. The most used categories are stress-timing, syllable-timing, and mora-timing. Traditional rhythm typology has been questioned by instrumental research, because the claimed isochronous units have not been found. Speech cycling is a method that endeavours to find regular rhythmic units by utilising repeated speech that the speaker produces by accommodating to regularly paced stimuli. This is intended to eliminate the irregularities that would otherwise hide the linguistic rhythm. The present study is a speech cycling experiment on Finnish. The subjects read sentences that were varied in the mora and syllable count. The locations of the stressed syllables were analysed on a relative scale to see if they appear at regular phases. The results show that in Finnish the mora, the syllable, and the quantity pattern all affect the phases.
As children learn more about language, they use it more effectively to achieve their conversational goals. They choose appropriate speech acts, establish joint attention, contribute new information, take up information from others, and take turns. They learn how to enter an exchange among others from as young as age two. Their intrusions in ongoing exchanges typically contain new information. Planning an utterance takes time, and children learn to plan what to say so as to take turns on time. This can be tracked in their answers to yes/no and wh- questions, where they get faster with age. They plan pretend play, assigning roles, assigning actions, and also utterances for each character enacted. They track common ground and design referring expressions for their addressees, and they repeat new words to mark uptake. They distinguish requests from offers, and, on occasion, persist in making repeated requests themselves. They clarify what they mean when asked and offer spontaneous repairs as well. In all this, they track what the others in the exchange say and choose when to enter the exchange themselves.
The best public speakers use a series of tricks to enchant an audience. They are revealed in this chapter and include: incorporating interactions to make a crowd feel part of the performance, signposting to continually refresh interest, the showbusiness of magic moments for truly memorable talks, the use of commanding body language, how to deal with nerves and preparing for the question and answer session.
Muscovite-kaolinite intergrowths found in Albian sandstones of the Basque Cantabrian basin (northern Spain) were studied by optical, scanning and electron microscopy and electron microprobe analysis. Kaolinitization begins at grain edges, forming the characteristic fanned-out textures, and propagates toward the interior along the cleavages of muscovite. Kaolinite and muscovite occur as thick packets, being free of interlayering. Phase boundaries between both minerals show bidimensional crystallographic continuity, and no intermediate phases have been identified. The data obtained suggest that muscovite only supplied a template suitable for the epitactic crystallization of kaolinite, while Al was available in sufficient amounts due to the dissolution of detrital K-feldspar. Very small packets of magnetite or maghemite showing a coherent orientation with the kaolinite crystals have been recognized, and could be responsible for the small Fe contents usually detected in electron microprobe analyses of kaolinite.
Textural relationships between authigenic kaolinite and deformation microstructures in the intergrowths, combined with previous information about burial conditions, show that alteration proceeded during a late stage of the diagenetic history, related to the uplift of the studied materials as a result of the Alpine orogeny.
This chapter introduces the forty-six policy episodes that we study in detail. We present their timing, their politicization, and their substantive focus. The association between politicization and pressure, both problem and political pressures, proves to be rather variable across member states and looser than expected. We account for this finding by taking into account the endogenous political dynamics during the crisis. Policy responses at the national level were not only required by the failure of the CEAS and by the inability of the leaders to adopt joint solutions at the EU level, they were also the result of a series of endogenous factors at the national level, which operated independently of problem pressure and, in part at least, created the political pressure in the first place. The strategies of political entrepreneurs – Orbán, Salvini, Seehofer, and Erdogan – most clearly fit this bill, but anticipation of crisis situations to come, legislative cycles, conspicuous events like terrorist attacks, and sequels of policy decisions made earlier in the crisis all contributed to these endogenous dynamics.
This chapter contains four parts. To some, questions of time and politics may appear extraneous – they may be valid issues to study but not a central concern for contemporary IR, much less a necessary one. For them, it is just another area of study and deciding whether to pursue it is a matter of personal choice. The first section shows how international politics and time are already intertwined and argues that time impacts the main issues of concern for IR. The second shows how IR is “stuck in the past” – even as it furiously gestures toward the future – because it theorizes temporality and time as universal and linear, privileging the past, all while resisting thinking about the present. The third section briefly introduces what I call presentism, an alternative temporal imaginary for IR that explicitly values the present, thinks in time, and resists naturalizing the contemporary political dominance of universal, linear time. The final section outlines the rest of the book, identifying theoretical and conceptual implications, concretizing both by showing how it enables a different perspective on war, American foreign policy during the Trump administration, and IR’s primary theoretical architectures.
The concept of superposed fracture networks consisting of different generations, and often types, of fractures that have developed sequentially is discussed. Superposed networks can consist of different types of extension or shear fractures, and each fracture may abut, cross or follow (reactivate) earlier fractures. An example of a superposed fracture network in Liassic limestones in Somerset, UK, is presented, which comprises two sets of veins and a later joint network. The veins develop as damage zones around faults, with veins of the later set crossing or trailing along the earlier set. The later joints either cross-cut the earlier veins or reactivate them, the latter being common for the thicker (more than about 5 mm) veins. The veins and joint networks have markedly different geometries and topologies. The veins are spatially clustered and are typically dominated by I-nodes, while the joints are more evenly distributed and tend to be dominated by Y-nodes. The combined network of veins and joints at Lilstock is dominated by X-nodes because so many joints cross-cut the earlier veins. Understanding the development of superposed fracture networks leads to better understanding of the kinematic, mechanical, tectonic and fluid flow history of rocks.
Although diagnostic instability in first-episode psychosis (FEP) is of major concern, little is known about its determinants. This very long-term follow-up study aimed to examine the diagnostic stability of FEP diagnoses, the baseline predictors of diagnostic change and the timing of diagnostic change.
Methods
This was a longitudinal and naturalistic study of 243 subjects with FEP who were assessed at baseline and reassessed after a mean follow-up of 21 years. The diagnostic stability of DSM-5 psychotic disorders was examined using prospective and retrospective consistencies, logistic regression was used to establish the predictors of diagnostic change, and survival analysis was used to compare time to diagnostic change across diagnostic categories.
Results
The overall diagnostic stability was 47.7%. Schizophrenia and bipolar disorder were the most stable diagnoses, with other categories having low stability. Predictors of diagnostic change to schizophrenia included a family history of schizophrenia, obstetric complications, developmental delay, poor premorbid functioning in several domains, long duration of untreated continuous psychosis, spontaneous dyskinesia, lack of psychosocial stressors, longer duration of index admission, and poor early treatment response. Most of these variables also predicted diagnostic change to bipolar disorder but in the opposite direction and with lesser effect sizes. There were no significant differences between specific diagnoses regarding time to diagnostic change. At 10-year follow-up, around 80% of the diagnoses had changed.
Conclusions
FEP diagnoses other than schizophrenia or bipolar disorder should be considered as provisional. Considering baseline predictors of diagnostic change may help to enhance diagnostic accuracy and guide therapeutic interventions.
A robust association has been reported between childhood adverse life events (ALEs) and risky substance use in adolescence. It remains unclear, however, what the impact of type and timing of these ALEs is. We investigated the association between ALEs and substance use in adolescents. ALEs were operationalized as broad (e.g., moving, parental divorce, family sickness) or physically threatening (physical and/or sexual abuse). First, we examined lifetime ALEs, followed by an investigation into their timing. The sample consisted of 909 adolescents (aged 12–18 years) from a cohort oversampled on high levels of emotional and behavioral problems. The primary caregiver indicated which ALEs each adolescent experienced across their lifetime. Adolescents self-reported on number and frequency of substances used. Poisson and ordinal regression models were used to model the associations. The associations between lifetime ALEs and a substance used were observed only for physical ALEs (incidence rate ratio 1.18 [1.03, 1.35], p = 0.02). When investigating timing, physical ALEs after the age of 12 predicted number of substances used (IRR 1.36 [1.13, 1.63], p < .001). Recent ALEs (occurring after age 12) seem to have considerable impact on substance use. Alcohol and drugs as a coping mechanism were considered a plausible explanation for the results.
With the increase in hectares planted to auxin-resistant cotton, the number of preplant, at-plant, and postplant applications of dicamba and 2,4-D choline to aid in the control of troublesome broadleaf weeds, including glyphosate-resistant Palmer amaranth, has increased. More dicamba and 2,4-D choline applications mean an increased risk of off-target movement. Field studies were conducted in 2019 to 2021 at the Texas Tech University New Deal Research Farm to evaluate dicamba-resistant cotton response to various rates of 2,4-D choline when applied at four growth stages (first square [FS] + 2 wk, first bloom [FB], FB + 2 wk, and FB + 4 wk). Applications of 2,4-D choline were applied at 1,060 (1X), 106 (1/10X), 21 (1/50X), 10.6 (1/100X), 2.1 (1/500X), and 1.06 (1/1000X) g ae ha−1 to Deltapine 1822 XF cotton. Relative to the nontreated control, yield losses were observed in all years at FS + 2 wk and FB from rates of 2,4-D choline ≥ 1/100X. At the FB + 4 wk application, only the 1X rate of 2,4-D choline resulted in a yield reduction in all three years. Micronaire, fiber length, and uniformity were negatively influenced by the 1/10X and 1X rates of 2,4-D choline at various timings in 2019, 2020, and 2021. In addition, short fiber content, neps, and seed coat neps increased where micronaire, fiber length, and uniformity were negatively impacted.
Physical time refers to five context-independent elements of time: tempo, duration, timing, sequencing, and stages. It makes two contributions. It refines the analysis of historical time by focusing on the rhytms in which it unfolds. It thus supplements the analysis of what changes in content by paying attention to how it changes in rhythm. It also refines causal analysis by treating the elements of physical time that produce distinct causal effects; these are frequently overlooked by linear notions of causality. CHA employs both physical time and historical time, and this distinguishes it from other methodologies. It configures these elements of time in distinct ways, which define the three strands of CHA: eventful, longue durée, and macro-causal analysis.
Legislators must decide when, if ever, to cosponsor legislation. Scholars have shown legislators strategically time their positions on salient issues of national importance, but we know little about the timing of position-taking for routine bills or what this activity looks like in state legislatures. We argue that legislators’ cosponsorship decision-making depends on the type of legislation and the partisan dynamics among the current cosponsors. Members treat everyday legislation as generalized position-taking motivated by reelection, yet for key legislation, legislators are policy-oriented. With a new dataset of over 73,000 bills introduced in both chambers of the Texas state legislature in the 75th to 86th regular sessions (1997–2020), we use pooled Cox proportional hazard models to evaluate the dynamics of when legislators legislate, comparing all bills introduced with a subset of key bills. The results show that legislators time their cosponsorship activity in response to electoral vulnerability, partisanship, and the dynamics of the chamber in which they serve.
Why is birth so dangerous, even today, with modern medicine? Through historical anecdote and a contemporary case history we explore this question, discussing the process of birth and what can go wrong. By thinking about who is in control of labour – is it the mother or her fetus? – we think about how a couple might prepare for birth. The challenge posed by birth makes us look to human evolution for answers, and we describe the insight it gives into birth in some low-resource settings around the world. We tackle the question of the rising numbers of caesarean sections around the world and the possible consequences. Although it may be widely believed that a smaller baby would mean a less difficult birth, we go on to explore the risks of being small for the survival of the baby alongside new research revealing how the mother’s body limits the growth of her baby inside the womb. We discuss whether the growth of the fetus is set by the genes which the mother or the father have passed on, mother’s size, or her environment. This leads to how the fetus develops and what controls this, the focus of the next chapter.
Payne offers an account of the unsettling effects of confessions of violence by armed left guerillas or revolutionary fighters in Argentina in two moments in Argentine history. The chapter considers how the timing of these confessions shaped responses to them. In the years shortly after the transition from authoritarian rule, contentious debate moved toward a full accounting on the left for its role in past violence. In recent years, this proved less possible. As the right reconsolidated its political power, the confessional narratives from the Argentine armed left fueled fears of a backlash against the left, reinforcing a view of the left’s shared responsibility with the authoritarian regime for human rights violations, and a call for its prosecution. This silencing of open debate over the left’s past actions prevented the process of condemning violations regardless of who committed them. The prescriptive dimension to this observation highlights the need for urgency in thinking self-critically, to reflect broadly on the motives and consequences of violence, and to use moments of political advantage to condemn those parts of the (temporarily) dominant power’s past that deserve condemnation.
