The Relationship

Three experiments explored the relationship between chroma-salience profiles of individual chords and tone profiles obtained after short chord progressions. Musicians' tone profiles for diatonic progressions of one, two, and three chords were compared with predictions of three models: a bottom- up stimulus model (number of times each chroma occurs in the progression), a top-down or schema-driven key model (best-fitting key profile of C. L. Krumhansl & E. J. Kessler, 1982), and an intermediate pitch model that includes both top-down and bottom-up components (cumulative pitch salience; R. Parncutt, 1989, 1993). For single chords, all predictors significantly matched tone profiles, except the key model applied to the diminished triad. For pairs of chords, the pitch and key models consistently outperformed the stimulus model, consistent with the assumption that a (top- down) key had been established; in the pitch model, the second chord influenced the tone profile more than the first (recency effect). Progressions of three chords comprised forward (e. g., FG-C) and backward (C-G-F) cadences in major and minor keys. The pitch and key models were successful for all progressions, but the key model predicted the tonic of backward cadences in C major and minor to be F. Predictions of the stimulus model were clearly worse than those of the other models, especially for backward cadences. Both primacy and recency effects were observed. In summary, the pitch model was the most consistently successful model over all experiments. To successfully predict tone profiles following chord progressions, it was necessary to account not only for recency (and primacy) but also for variations in pitch salience within chords. Results are consistent with a model of tonality induction in which bottom-up processes interact in real time with top-down processes of two kinds: recognition of harmonic pitch patterns and recognition of key profiles.

The Relationship

An aspect of the relationship between philosophy and computer engineering is considered, with particular emphasis upon the design of artificial moral agents. Top-down vs. bottom-up approaches to ethical behavior are discussed, followed by an overview of some of the ways in which traditional ethics has informed robotics. Two macro-trends are then identified, one involving the evolution of moral consciousness in man and machine, the other involving the fading away of the boundary between the real and the virtual.

The interactive roles of zooplankton grazing (top-down) and nutrient (bottom-up) processes on phytoplankton distribution in a temperate estuary were investigated via dilution and nutrient addition experiments. The responses of size-fractionated phytoplankton and major phytoplankton groups, as determined by flow cytometry, were examined in association with zooplankton grazing and nutrient availability. The summer bloom was attributed to nanoplankton, and microplankton was largely responsible for the winter bloom, whereas the picoplankton biomass was relatively consistent throughout the sampling periods, except for the fall. The nutrient addition experiments illustrated that nanoplankton responded more quickly to phosphate than the other groups in the summer, whereas microplankton had a faster response to most nutrients in the winter. The dilution experiments ascribed that the grazing mortality rates of eukaryotes were low compared to those of the other groups, whereas autotrophic cyanobacteria were more palatable to zooplankton than cryptophytes and eukaryotes. Our experimental results indicate that efficient escape from zooplankton grazing and fast response to nutrient availability synergistically caused the microplankton to bloom in the winter, whereas the bottom-up process (i.e., the phosphate effect) largely governed the nanoplankton bloom in the summer.

<p>Following the 2010 and 2011 Canterbury earthquakes, earthquake strengthening is one of the biggest issues facing heritage buildings in New Zealand. This process is mainly affecting commercial and public buildings; residential buildings are generally exempt from earthquake-prone building policies. However, some homeowners are choosing to do what is often perceived to be an expensive and time-consuming process. This research explores whether there is a heritage relationship between the homeowner and their house that motivates conservation work, such as earthquake strengthening. The central question for this research is: “What makes a heritage house a home? Is “home” a motivation for owners to earthquake strengthen their building? a case study of Dunedin”.  The relationship between homeowners and the heritage of their homes and domestic conservations practices has been underexamined in heritage studies in New Zealand. The current dissertation addresses this problem and contributes to the literature of Museum and Heritage Studies. The theoretical framework employed in this research draws on the field of Critical Heritage Studies in order to explore the relationship between ‘top-down’ and ‘bottom-up heritage’, the notion of ‘peoples-based’ heritage, the value of intangible heritage and a cycle of care. This research utilised qualitative research methods, involving the interviewing three heritage homeowners and two heritage professionals. These provided detailed findings about homeowners’ perceptions of their houses and the interaction between heritage practitioners and homeowners. The southern city of Dunedin was the case study which framed this research, because it has a rich collection of heritage buildings and a council which has been proactive in encouraging earthquake strengthening.  It was found that the heritage homeowner’s relationship with their home played a role in conservation how decisions are undertaken and that there is a lack of outreach from heritage authorities to heritage homeowners. This research provides information about the nature of the interaction between top-down and bottom-up heritage, and how this relationship can lead to positive heritage outcomes. Recommendations include developing open channels of communication between officials and homeowners, increased acknowledgement of the homeowner’s role in the conservation practice, and the establishment of a concept of Domestic Heritage to assist within the development of a cycle of care by heritage homeowners.</p>

Institutional Choices

There are two ways of thinking about institutional choice in the context of multilateral investment law reform. One starts from abstract principles, asking what policy goal investment law is supposed to achieve and what institutional choice most effectively advances that goal. The other draws on practical experimentation, asking what institutional choices states are making and how these choices perform in real life. Sergio Puig and Gregory Shaffer present a compelling analytical framework for the former, top-down approach to investment law reform. In this essay, I will scrutinize their analysis and argue that the latter, bottom-up approach is more promising.

Abstract. Real-time, single-particle fluorescence instruments used to detect atmospheric bioaerosol particles are increasingly common, yet no standard fluorescence calibration method exists for this technique. This gap limits the utility of these instruments as quantitative tools and complicates comparisons between different measurement campaigns. To address this need, we have developed a method to produce size-selected particles with a known mass of fluorophore, which we use to calibrate the fluorescence detection of a Wideband Integrated Bioaerosol Sensor (WIBS-4A). We use mixed tryptophan–ammonium sulfate particles to calibrate one detector (FL1; excitation  =  280 nm, emission  =  310–400 nm) and pure quinine particles to calibrate the other (FL2; excitation  =  280 nm, emission  =  420–650 nm). The relationship between fluorescence and mass for the mixed tryptophan–ammonium sulfate particles is linear, while that for the pure quinine particles is nonlinear, likely indicating that not all of the quinine mass contributes to the observed fluorescence. Nonetheless, both materials produce a repeatable response between observed fluorescence and particle mass. This procedure allows users to set the detector gains to achieve a known absolute response, calculate the limits of detection for a given instrument, improve the repeatability of the instrumental setup, and facilitate intercomparisons between different instruments. We recommend calibration of single-particle fluorescence instruments using these methods.

The Relationship

Background: While investigating the real-time impedance at acupuncture points (acupoints), it was found that regular sinusoidal waves were present that corresponded to the pulsing of certain organs, such as respiration and duodenal waves, the stomach&rsquo;s slow waves, and also the heart&rsquo;s beating.Methods: This study investigated such respiration waves at lung-related acupoints to clarify their relation to the respiration pacesetter mechanism. The impedance at key acupoints was monitored in real time while the patients&rsquo; breathing slowed after exercise.Results: In all 7 patients studied, the respiration and heart-beat waves matched the rates in the corresponding organs at rest, and did not vary markedly due to exercise. In 3 of the 7 patients, their post-exercise respiration rate exactly matched that of their duodenal waves, but then dropped, stepwise, back to their usual respiration rate. In the other 4 patients, their post-exercise respiration rate did not reach that of their duodenal waves, so this pattern was not triggered.Conclusion: The results suggested that as well as the brainstem respiration pacesetter, there was also a separate &ldquo;pace signal&rdquo; present which remained constant and seemed to define the respiration rate when at rest. It is currently unknown what mechanism causes the respiration rate to increase due to exercise. But these results suggest that the brainstem pacesetter is sometimes guided by the duodenal pace signal instead of the lung pace signal, which may explain how the pacesetter is able to jump to a higher rate, even though its chemoreceptor inputs may be unchanged.

Response Habituation

The repetition of nociceptive stimuli of identical modality, intensity, and location at short and constant interstimulus intervals (ISIs) determines a strong habituation of the corresponding EEG responses, without affecting the subjective perception of pain. To understand what determines this response habituation, we (i) examined the effect of introducing a change in the modality of the repeated stimulus, and (ii) dissected the relative contribution of bottom–up, stimulus-driven changes in modality and top–down, cognitive expectations of such a change, on both laser-evoked and auditory-evoked EEG responses. Multichannel EEG was recorded while participants received trains of three stimuli (S1–S2–S3, a triplet) delivered to the hand dorsum at 1-sec ISI. S3 belonged either to the same modality as S1 and S2 or to the other modality. In addition, participants were either explicitly informed or not informed of the modality of S3. We found that introducing a change in stimulus modality produced a significant dishabituation of the laser-evoked N1, N2, and P2 waves; the auditory N1 and P2 waves; and the laser- and auditory-induced event-related synchronization and desynchronization. In contrast, the lack of explicit knowledge of a possible change in the sensory modality of the stimulus (i.e., uncertainty) only increased the ascending portion of the laser-evoked and auditory-evoked P2 wave. Altogether, these results indicate that bottom–up novelty resulting from the change of stimulus modality, and not top–down cognitive expectations, plays a major role in determining the habituation of these brain responses.

AbstractBackgroundPeople with schizophrenia process language in unusual ways, but the causes of these abnormalities are unclear. In particular, it has proven difficult to empirically disentangle explanations based on impairments in the top-down processing of higher level information from those based on the bottom-up processing of lower level information.MethodsTo distinguish these accounts, we used visual-world eye tracking, a paradigm that measures spoken language processing during real-world interactions. Participants listened to and then acted out syntactically ambiguous spoken instructions (e.g. ‘tickle the frog with the feather’, which could either specify how to tickle a frog, or which frog to tickle). We contrasted how 24 people with schizophrenia and 24 demographically matched controls used two types of lower level information (prosody and lexical representations) and two types of higher level information (pragmatic and discourse-level representations) to resolve the ambiguous meanings of these instructions. Eye tracking allowed us to assess how participants arrived at their interpretation in real time, while recordings of participants’ actions measured how they ultimately interpreted the instructions.ResultsWe found a striking dissociation in participants’ eye movements: the two groups were similarly adept at using lower level information to immediately constrain their interpretations of the instructions, but only controls showed evidence of fast top-down use of higher level information. People with schizophrenia, nonetheless, did eventually reach the same interpretations as controls.ConclusionsThese data suggest that language abnormalities in schizophrenia partially result from a failure to use higher level information in a top-down fashion, to constrain the interpretation of language as it unfolds in real time.

'Eliamani's Homestead' was shot as a result of long-term anthropological research in Tanzania and the translations were created in close cooperation with the Maasai research participants. Originally recorded for research purposes for a project on the relationship between images of and interactions with ‘the other’, the 20-minute single-shot includes jerky camera movements, but was left uncut and without voiceover in order to give the viewer a real-time experience of 'being there'. Within anthropology, the documentary invites to reflect on parallels between anthropology and tourism, and spurs debates regarding reflexivity. It addresses elements of the 'observer paradox' through the almost complete invisibility of the researcher’s camera, which stands in stark contrast with the obtrusive tourist cameras. That is, until Eliamani looks straight into the lens and dismissively comments upon the researcher’s camera too, making researcher and the documentary’s public part of the voyeuristic 'problem' as well. Outside anthropology, it invokes debates about how we see and interact with 'the other' in (cultural) tourism as well as in wider contexts. It thus addresses the question whether and how audiovisual data segments could be used to share anthropological knowledge inside and outside the discipline and academia.

Purpose of the study: To answer the two existing controversies regarding attention and consciousness as brain processes. 1) Can one be aware of objects or events without attending to it? 2) Can one attend to objects or events without being aware of it? And also how top-down attention and awareness have opposing functions. Methodology: This article is a systematic review of the relationship between visual attention and awareness. An extensive elaborate study on concepts relating to attention and consciousness dissociation has been done. In this article we also narrow it down to experimental design that requires independent manipulation of each. Which include top-down attention and awareness aspect of consciousness? Main Findings: Many researches have been put forward supporting the independent nature of attention from awareness using sophisticated experimental and physiological shreds of evidence. On the other hand, some researches still stick to the contemporary common-sense notion of no awareness no attention. Our evaluation suggests an independent nature of attention and awareness. Application: This article intends to give a clear perspective of the ongoing debate on the relationship between attention and consciousness. Simplification of both umbrella terms will give basis for building more empirical evidence. Novelty: Further, this article put forward studies on both sides of debate aiming to bridge the gap to get a conclusive outlook in the future.
