Objective: Clock variance is an important statistic in many clinical and developmental studies. Existing methods require a large number of trials for accurate clock variability assessment, which is problematic in studies using clinical or either young or aged participants. Furthermore, these existing methods often implicitly convolute clock and memory processes, making it difficult to disentangle whether the clock or memory system are driving the observed deviations. Here we assessed whether twenty repeated productions of a well-engrained interval (1 second), a task (...) that does not incorporate memory updating nor the processing of feedback, could provide an accurate assessment of clock variability. Method: Sixty-eight undergraduate students completed two tasks: a 1-second production task in which they were asked to produce a 1-second duration by ending a tone by a keypress, and a multi-duration reproduction task. Durations presented in the reproduction task were tones lasting 1.17, 1.4 and 1.68 seconds. No feedback was presented in either task, and the order of presentation was counterbalanced between participants. Results: The observed central tendency in the reproduction task was better explained by models including the measures of clock variability derived from the 1-second production task than by models without it. Three clock variability measures were calculated for each participant (standard deviation, root mean squared residuals (RMSR) from an estimated linear slope, and RMSR scaled by mean production duration). The model including the scaled RMSR was prefered over the alternative models, and no notable effects of the order of presentation were observed. These results suggest that (1) measures of variability should account for drift, (2) the presentation of another timing task before a 1-second production task did not influence the assessment of the clock variability, and (3) the observed variability adheres to the scalar property and predicts temporal performance, and is thus a usable index of clock variability. Conclusion: This study shows that just 20 repeated productions of 1 second provide a reliable index of clock variability. As administering this task is fast and easy, it could prove to be useful in a large variety of developmental and clinical populations. (shrink)

Fustel de Coulanges' thesis that ancient society was founded upon the cult of ancestral tombs has had, for a thoroughly self-contradictory argument, a remarkably successful career. Neither Fustel himself nor the many subsequent scholars who have quoted his views with approval faced clearly the difficulty of deriving a social structure dominated by corporate descent groups from the veneration of tombs placed in individually owned landed property. On the whole, historians have tended to play down Fustel's insistence on the relation between (...) ancestor-cult and property and to exaggerate the role of the corporate kin group. This tendency, which assimilates Fustel to Sir Henry Maine and other lawyers interested in the reconstruction of Indo-European institutions has in my view considerably impeded understanding of the role of kinship in early Greek society; it also obscures one of the most individual aspects of Fustel's work which, thanks to the researches of Philippe Ariès on the development of the modern tomb-cult in the nineteenth century, can now be placed in its historical context.

Three experiments explored online recognition in a nonspeech domain, using a novel experimental paradigm. Adults learned to associate abstract shapes with particular melodies, and at test they identified a played melody’s associated shape. To implicitly measure recognition, visual fixations to the associated shape versus a distractor shape were measured as the melody played. Degree of similarity between associated melodies was varied to assess what types of pitch information adults use in recognition. Fixation and error data suggest that adults naturally recognize (...) music, like language, incrementally, computing matches to representations before melody offset, despite the fact that music, unlike language, provides no pressure to execute recognition rapidly. Further, adults use both absolute and relative pitch information in recognition. The implicit nature of the dependent measure should permit use with a range of populations to evaluate postulated developmental and evolutionary changes in pitch encoding. (shrink)

Two recent books consider the future of trade governance.Consent and Tradeproposes reforms to trade agreements so that states can consent more freely to their terms.On Trade Justicedefends reforms to the World Trade Organization, arguing that multilateralism is the foundation for a “new global deal” on trade. Each book describes trade's distinctive features and proposes a principle to regulate both trade and trade governance.Consent and Tradedefends a principle of respect for state consent in trade agreements.On Trade Justiceoffers a theory of trade (...) justice that requires nonexploitation. Consent and nonexploitation are important principles for economic exchanges. However, trade governance and trade itself are different forms of cooperation, with different agents and different interests at stake. Consent and nonexploitation are less compelling as principles for trade governance than for trade itself. Both books understate the conflict between their principles for trade governance and liberal justice. (shrink)

Some recent trade decisions, such as the U.S.’s imposition of protectionist measures against China, have attracted fervent popular support as well as outrage. Critics of these trade policies argue that they fail to promote society’s own interests. This paper catalogues the different ways that trade decisions can hinder and facilitate a society’s pursuit of social justice. I adopt a simple description of trade liberalization: a society forgoes the use of certain policy options, in order to pursue greater economic productivity through (...) increased trade flows. Using this simple descriptive account, the paper identifies two pathways for a society’s trade policies to shape its pursuit of social justice. First, greater economic productivity improves a society’s capacities to realize justice, especially distributive justice. I will argue that the value of greater economic capacities depends upon the society’s existing capacities and its inclinations to pursue justice. When a society has greater capacities and fails to extend their benefits to its worse-off citizens, these citizens have more serious grounds for complaint. Second, a society forgoes certain policy options when it liberalizes trade, and some of these options may be instrumentally valuable or even necessary for the society’s pursuit of justice. I will argue that, under non-ideal conditions, it can be desirable for a society to limit its own policy space so it cannot feasibly select policies that are unjust. Certain protectionist policies have taken on the expressive meaning that some groups are inferior in social and moral status. (shrink)

The Scourge of God: The Umman-manda and Its Significance in the First Millennium BC. By Selim Ferruh Adali. State Archives of Assyria Studies, vol. 20. Helsinki: The Neo-Assyrian Text Corpus ProJect, 2011. Pp. xviii + 218. $62.

In her recent book, Svärd uses theories of hierarchical and heterarchical power to reveal how women wielded power within the highest echelons of the Assyrian Empire. Svärd determines that the queen occupied a distinct position in the state hierarchy, separate from the king, and that only one woman at a time could be queen. The queen could retain her post even after the king died, though the new king could replace her if he deemed it necessary. The king decided the (...) queen mother’s role, depending on political circumstances. Both queens and queen mothers ran large, lucrative estates and participated in religious ceremonies. During the Sargonid period, military units were attached to their households. In some official spheres of action, their power could be qualitatively similar to that of the king, and in a crisis, they could even act for him. Other women associated with the palace, such as royal daughters, female administrators, and workers, were more apt to develop power heterarchically, through petitions, negotiation, or communication networks. Wishing to expand upon her theoretical approach, Svärd has studied diachronic changes in Assyrian queenship, concluding that the office developed to meet the needs of family and dynasty. In addition, I argue here that the demands of an expanding empire required the king to delegate authority to trusted relatives. Thus, as the empire reached its peak under the Sargonid kings, royal women naturally gained power and prominence, and kings benefited. For example, the queen’s prosperous estates and business ventures allowed her to help fund the military as well as some temples and building projects, and so defray the costs to the throne. All of this shows that Assyrian women had individual agency and authority, and could influence the king’s decisions. Despite the value of theory, it is also necessary to consider women individually, in the context of their times, and as they responded to unique circumstances. (shrink)

Much research has explored developing sound representations in language, but less work addresses developing representations of other sound patterns. This study examined preschool children's musical representations using two different tasks: discrimination and sound–picture association. Melodic contour—a musically relevant property—and instrumental timbre, which is less musically relevant, were tested. In Experiment 1, children failed to associate cartoon characters to melodies with maximally different pitch contours, with no advantage for melody preexposure. Experiment 2 also used different-contour melodies and found good discrimination, whereas (...) association was at chance. Experiment 3 replicated Experiment 2, but with a large timbre change instead of a contour change. Here, discrimination and association were both excellent. Preschool-aged children may have stronger or more durable representations of timbre than contour, particularly in more difficult tasks. Reasons for weaker association of contour than timbre information are discussed, along with implications for auditory development. (shrink)

Shortages of life-saving medical resources caused by COVID-19 have prompted hospitals, healthcare systems, and governmentsto develop crisis standards of care, including 'triage protocols' to potentially ration medical supplies during the public health emergency. At the same time, the pandemic has highlighted and exacerbated racial, ethnic, and socioeconomic health disparities that together constitute a form of structural racism. These disparities pose a critical ethical challenge in developing fair triage systems that will maximize lives saved without perpetuating systemic inequities. Here we review (...) alternatives to 'utilitarian' triage, including first-come first-served, egalitarian, and prioritarian systems of allocating scarce medical resources. We assess the comparative advantages and disadvantages of these allocation schemes. Ultimately, we argue that while triage protocols should not exacerbate disparities, they are not an adequate mechanism for redressing systemic health inequities. Entrenched health disparities must be addressed through broader social change. (shrink)

Theories of cognitive development must address both the issue of how children bring their knowledge to bear on behavior in-the-moment, and how knowledge changes over time. We argue that seeking answers to these questions requires an appreciation of the dynamic nature of the developing system in its full, reciprocal complexity. We illustrate this dynamic complexity with results from two lines of research on early word learning. The first demonstrates how the child's active engagement with objects and people supports referent selection (...) via memories for what objects were previously seen in a cued location. The second set of results highlights changes in the role of novelty and attentional processes in referent selection and retention as children's knowledge of words and objects grows. Together this work suggests that understanding systems for perception, action, attention, and memory, and their complex interaction, is critical to understand word learning. We review recent literature that highlights the complex interactions between these processes in cognitive development and point to critical issues for future work. (shrink)

Summary 1. Ecologists and conservation biologists consider many issues when designing a field study, such as the expected value of the data, the interests of the study species, the welfare of individual organisms and the cost of the project. These different issues or values often conflict; however, neither animal ethics nor environmental ethics provides practical guidance on how to assess trade-offs between them. -/- 2. We developed a decision framework for considering trade-offs between values in ecological research, drawing on the (...) field of ecological ethics. We used a case study of the population genetics of three frog species, in which a researcher must choose between four methods of sampling DNA from the study animals. We measured species welfare as the reduction in population growth rate following sampling, and assessed individual welfare using two different definitions: (i) the level of suffering experienced by an animal, and (ii) the level of suffering combined with loss of future life. -/- 3. Tipping the tails of tadpoles ranked as the best sampling method for species welfare, while collecting whole tadpoles and buccal swabbing of adult frogs ranked best for the first and second definitions of individual welfare, respectively. Toe clipping of adult frogs ranked as the worst sampling method for species welfare and the first definition of individual welfare, and equal worst for the second definition of individual welfare. -/- 4. When considering species and individual welfare simultaneously, toe clipping was clearly inferior to the other sampling methods, but no single sampling method was clearly superior to the other three. Buccal swabbing, collecting tadpoles and tail tipping were all preferred options, depending on the definition of individual welfare and the level of precision with which we assessed species welfare. -/- 5.Synthesis and applications. The decision framework we present can be used by ecologists to assess ethical and other trade-offs when planning field studies. A formal decision analysis makes transparent how a researcher might negotiate competing ethical, financial and practical objectives. Defining the components of the decision in this way can help avoid errors associated with human judgement and linguistic uncertainty. (shrink)

In response to the need for a more diverse workforce, our medical school developed new policies and procedures that focus on the recruitment and selection of diverse students with a specific focus on those considered underrepresented in medicine. To understand what these students bring to the practice of medicine, researchers investigated their perception of their cultural assets and how they plan to use these assets as physicians. A cross-section of 23 ethnically, culturally, and geographically diverse medical students were interviewed and (...) data were analyzed through phenomenographical methods. The results indicate that students view themselves as having multiple assets that could be of significant value in their future practice of medicine, including: a) an interest in science and access to family members in medicine, b) personal and familial struggles with health, c) self and family as immigrants, and d) strong family and community orientations. Students perceived these as cultural assets because they could directly identify where these assets could be valuable in medicine but questioned how to maintain them throughout medical school. Now that our institution has identified these assets, next steps include administrators' investigation of ways to leverage them through curricular and educational programs. (shrink)

Patients fit with cochlear implants commonly indicate at the time of device fitting and for some time after, that the speech signal sounds abnormal. A high pitch or timbre is one component of the abnormal percept. In this project, our aim was to determine whether a number of years of CI use reduced perceived upshifts in frequency spectrum and/or voice fundamental frequency. The participants were five individuals who were deaf in one ear and who had normal hearing in the other (...) ear. The deafened ears had been implanted with a 18.5 mm electrode array which resulted in signal input frequencies being directed to locations in the spiral ganglion that were between one and two octaves higher than the input frequencies. The patients judged the similarity of a clean signal presented to their implanted ear and candidate, implant-like, signals presented to their normal-hearing ear. Matches to implant sound quality were obtained, on average, at 8 months after device activation and at 35 months after activation. At Time 1, the matches to CI sound quality were characterized, most generally, by upshifts in the frequency spectrum and in voice pitch. At Time 2, for four of the five patients, frequency spectrum values remained elevated. For all five patients F0 values remained elevated. Overall, the data offer little support for the proposition that, for patients fit with shorter electrode arrays, cortical plasticity nudges the cortical representation of the CI voice toward more normal, or less upshifted, frequency values between 8 and 35 months after device activation. Cortical plasticity may be limited when there are large differences between frequencies in the input signal and the locations in the SG stimulated by those frequencies. (shrink)
