Learning Trials

Episodic memory has been studied extensively in the past few decades, but so far little is understood about how it is used to affect behavior. Here we postulate three learning paradigms: one-shot learning, replay learning, and online learning, where in the first two paradigms episodic memory is retrieved for decision-making or replayed to the neocortex for extracting semantic knowledge, respectively. In the third paradigm, the neocortex directly extracts information from online experiences as they occur, but does not have access to these experiences afterwards. By using visually-driven reinforcement learning in simulations, we found that whether an agent is able to solve a task by relying on the three learning paradigms depends differently on the number of learning trials and the complexity of the task. Episodic memory can, but does not always, have a major benefit for spatial learning, and its effect differs for the two modes of accessing episodic information. One-shot learning is initially faster than replay learning, but the latter reaches a better asymptotic performance. We believe that understanding how episodic memory drives behavior will be an important step towards elucidating the nature of episodic memory.

Concrete Action

Narrative-Based Decision Theory (NBDT) describes how narrative thinking leads to concrete action. The first premise is that narratives enable the narrator to make sense of the past and present and allow him or her to make plausible forecasts about the future. The second premise is that the narrator can evaluate the desirability of the forecasted future in light of his or her values and preferences. The third premise is that when the forecasted future is undesirable the narrator can create and implement plans of action aimed at ensuring that the future, when it arrives, is more desirable than what was forecasted. Two kinds of decisions bind these three premises into a unified theory: decisions about the desirability of the forecasted future and decisions about a plan’s potential for remedying things when it is decided that the forecasted future is undesirable — in effect, the plan’s desirability. Both kinds of decisions are made using a single mechanism, the discrepancy test. The NBDT viewpoints on the properties of narratives, on the properties of decisions, and on the properties of the decision mechanism are discussed.

General Conditions

Diplomacy is the third leg of a holistic strategy we propose for managing conflict between America and China. Some general conditions help to make it effective, although its specific operation is always context-dependent. Leadership commitment is often necessary for launching major diplomatic initiatives. Leadership commitment is often the result of internal or external incentives, reinforced by catalysts that highlight pressing challenges and the imperative of diplomacy. Effective diplomacy also requires sound strategic conceptions. A smooth decision-making process capable of coordinating disparate policy preferences and implementing supportive policies is also critical to effective diplomacy. Diplomacy has had major successes and regrettable failures in managing the Sino-American relationship in the past. Looking ahead, it faces both opportunities and constraints in managing competition between the two countries.

The Mind

The ʿUthmānic way of writing (al-rasm al-ʿUthmānī) is a science that specialises in the writing of Qur'anic words in accordance with a specific ‘pattern’. It follows the writing style of the Companions at the time of the third caliph, ʿUthmān b. ʿAffān, and was attributed to ʿUthmān on the basis that he was the one who ordered the collection and copying of the Qur'an into the actual muṣḥaf. This article aims to expound on the two fundamental functions of al-rasm al-ʿUthmānī: that of paying regard to the ‘correct’ pronunciation of the words in the muṣḥaf, and the pursuit of the preclusion of ambiguity which may arise in the mind of the reader and his auditor. There is a further practical aim for this study: to show the connection between modern orthography and the ʿUthmānic rasm in order that we, nowadays, are thereby able to overcome the problems faced by calligraphers and writers of the past in their different ages and cultures.

The story of Lot is one of many shared by the Qur'an and the Torah, and Lot's offer of his two daughters to his people is presented in a similar way in the two books. This article compares the status of Lot in the Qur'an and Torah, and explores the moral dimensions of his character, and what scholars of the two religions make of this story. The significance of the episodes in which Lot offers his daughters to his people lies in the similarities and differences of the accounts given in the two books and the fact that, in both the past and the present, this story has presented moral problems and criticism has been leveled at Lot. Context is crucial in understanding this story, and exploration of the ways in which Lot and his people are presented is also useful in terms of comparative studies of the two scriptures. This article is divided into three sections: the first explores the depiction of Lot in the two texts, the second explores his moral limitations, and the third discusses the interpretations of various exegetes and scholars of the two books. Although there are similarities between the Qur'anic and Talmudic accounts of this episode, it is read differently by scholars from the two religions because of the different contexts of the respective accounts.

This article offers a ‘post-heritage’ reading of both iterations of Upstairs Downstairs: the LondonWeekend Television (LWT) series (1971–5) and its shortlived BBC revival (2010–12). Identifying elements of subversion and subjectivity allows scholarship on the LWT series to be reassessed, recognising occasions where it challenges rather than supports the social structures of the depicted Edwardian past. The BBC series also incorporates the post-heritage element of self-consciousness, acknowledging the parallel between its narrative and the production’s attempts to recreate the success of its 1970s predecessor. The article’s first section assesses the critical history of the LWT series, identifying areas that are open to further study or revised readings. The second section analyses the serialised war narrative of the fourth series of LWT’s Upstairs, Downstairs (1974), revealing its exploration of female identity across multiple episodes and challenging the notion that the series became more male and upstairs dominated as it progressed. The third section considers the BBC series’ revised concept, identifying the shifts in its main characters’ positions in society that allow the series’ narrative to question the past it evokes. This will be briefly contrasted with the heritage stability of Downton Abbey (ITV, 2010–15). The final section considers the household of 165 Eaton Place’s function as a studio space, which the BBC series self-consciously adopts in order to evoke the aesthetics of prior period dramas. The article concludes by suggesting that the barriers to recreating the past established in the BBC series’ narrative also contributed to its failure to match the success of its earlier iteration.

Adaptive Problem

To live well in the present, we take direction from the past. Yet, individuals may engage in a variety of behaviors that distort their past and current circumstances, reducing the likelihood of adaptive problem solving and decision making. In this article, we attend to self-deception as one such class of behaviors. Drawing upon research showing both the maladaptive consequences and self-perpetuating nature of self-deception, we propose that self-deception is an understudied risk and maintaining factor for psychopathology, and we introduce a “cognitive-integrity”-based approach that may hold promise for increasing the reach and effectiveness of our existing therapeutic interventions. Pending empirical validation of this theoretically-informed approach, we posit that patients may become more informed and autonomous agents in their own therapeutic growth by becoming more honest with themselves.

While geologists are still considering whether the Anthropocene should be accepted as a formal geological epoch, it is up to us humanists to search for ways making this human era a good one. In this article, I will examine how we can use historical research to provide such tracks based on past regularities or similarities. Positive success stories from the past can at least provide faith that we can do something about our current environmental problems. This investigation is based on two case studies: the Tesla Model S electric car, and the Swedish pulp and paper industry's transition to chlorine-free bleaching. It argues that the sustainability revolution doesn't just share similarities with the quality movement of the 1970s and 1980s, but is essentially a continuation of it. In concordance with previous megatrends, the major benefit of the sustainability revolution will be reaped by countries and companies running ahead of the curve. A new term, 'trail-blazer dependency' is introduced; by setting an example, the first-movers are opening a trail for late-comers to follow.
