Learn A Robust Representation For Cover Song Identification Via Aggregating Local And Global Music Temporal Context

We tend to mentally segment a series of events according to perceptual contextual changes, such that items from a shared context are more strongly associated in memory than items from different contexts. It is also known that temporal context provides a scaffold to structure experiences in memory, but its role in event segmentation has not been investigated. We adapted a previous paradigm, which was used to investigate event segmentation using visual contexts, to study the effects of changes in temporal contexts on event segmentation in associative memory. We presented lists of items in which the inter-stimulus intervals (ISIs) ranged across lists between 0.5 and 4 s in 0.5 s steps. After each set of six lists, participants judged which one of two test items were shown first (temporal order judgment) for items that were either drawn from the same list or from consecutive lists. Further, participants judged from memory whether the ISI associated to an item lasted longer than a standard interval (2.25s) that was not previously shown. Results showed faster responses for temporal order judgments when items were drawn from the same context, as opposed to items drawn from different contexts. Further, we found that participants were well able to provide temporal duration judgments based on recalled durations. Finally, we found temporal acuity, as estimated by psychometric curve fitting parameters of the recalled durations, correlated inversely with within-list temporal order judgments. These findings show that changes in temporal context support event segmentation in associative memory.

Ways Of Thinking

This chapter reviews the history of green entrepreneurship, arguing that green entrepreneurship was shaped by four different temporal contexts between the mid-nineteenth century and the present day. Although there were significant achievements over the entire period, it was only in the most recent era that green business achieved legitimacy and scale. Green entrepreneurs often had religious and ideological motivations, but they were shaped by their institutional and temporal context. They created new markets and categories through selling their ideas and products, and by imagining the meaning of sustainability. They faced hard challenges, which encouraged clustering which provided proximity advantages and higher trust levels. Combining profits and sustainability has always been difficult, and the spread of corporate environmentalism in recent decades has not helped. Although commercial success often eluded pioneers, by a willingness to think outside of traditional boxes, they have opened up new ways of thinking about sustainability.

Level Analysis

The field of pre-1830 South African history has been subject to periodic interrogations into conventional narratives, sources, and methods. The so-called mfecane debates of the 1980s and 1990s marked a radical departure from characterizations of warfare in the interior, generally regarded in earlier decades as stemming solely or mostly from the Zulu king Shaka. Efforts to reframe violence led to more thorough considerations of political elites and statecraft from the late eighteenth to the early nineteenth century but also contributed to new approaches to ethnicity, dependency, and to some extent gender. A new wave of historiographical critique in the 2010s shows the work of revision to be ongoing. The article considers the debates around the wars of the late precolonial period, including unresolved strands of inquiry, and argues for a move away from state-level analysis toward social histories of women and non-elites. Though it focuses on the 1760s through the 1830s, the article also presents examples highlighting the importance of recovering deeper temporal context for the South African interior.
