Regret as Autobiographical Memory

Abstract An autobiographical memory framework for the study of regret is contrasted with traditional decision-making approaches to regret. Based on the autobiographical memory framework a memory-based distinction is introduced between regrets for specific and general events. Across 6 studies the distinction is applied to issues related to the temporal pattern of regret and to survey data showing that long term inaction regrets tend to concern experiences from early adulthood. Studies 1 and 2 examined the temporal distribution of experienced regrets within the context of the “reminiscence bump” phenomenon from autobiographical memory research. Participants regretted proportionally more experiences from early adulthood than from elsewhere in the lifespan, but this pattern obtained for general regrets only: specific regrets were more randomly distributed and tended to concern more recent events. General regrets were more likely to concern inactions than actions, whereas specific regrets were as likely to concern actions as inactions. Consistent with regret surveys, the most frequently reported regrets concerned family, intimate relationships (including marriage and parenting), education, work, character and self-actualisation. These findings were interpreted with reference to life scripts. Studies 3 and 4 assessed the contribution of the life script to the temporal distribution of imagined future regrets. Young adults imagined and dated experiences they anticipated either themselves (Studies 3 and 4a), a peer (Study 4b) or an average person (Study 4c) might regret in life. A preminiscence bump peaking in decade three was found for general regrets. Across Studies 3 and 4 imagined regrets focussed on similar experiences, were described in predominantly general terms and were overwhelmingly associated with inaction. The experienced regrets of young adults (Study 3) were similar in content to the regrets described by older adults about the same period (Studies 1 and 2). The results are interpreted as evidence that a culturally timetabled script deems some events more important and regret-worthy than others. Study 5 examined regret’s relationship with other emotions. Specific regrets more often evoked hot and moral emotions, while general regrets more often evoked wistful emotions, and neither type was more strongly associated with despair emotions. Study 5 also considered a distinction between self- and other-focussed regrets. Self-actualisation and other-focussed regrets were statistically indistinguishable and both were more likely than self-achievement regrets to evoke moral emotions such as guilt, remorse, and shame. Finally, Study 6 showed that general regrets had a broader impact than did specific regrets insofar as they affected more domains and produced more consequences. Across all of the studies in the thesis the domains of family, intimate relationships, character, education, work and self-development are the main source of real and imagined regrets. It is argued that the representation of event knowledge in autobiographical memory combined with culturally determined scripts together shape what people regret in life

Times Taxes and Voting Queues: The Voting Rights Act after Shelby County, Alabama v. Holder (2013)

The United States Supreme Court effectively dismantled the pre-clearance provision of the Voting Rights Act in Shelby County, AL v. Holder (2013). The majority asserts that “times have changed” and the relevant provisions of the VRA are now obsolete. This paper examines whether dismantling preclearance adversely affects how long racial and ethnic voters must wait to vote. The results show that the VRA reduces the time minority voters waited in line by one-half in the covered jurisdictions. After preclearance is dismantled, however, that benefit vanishes. Further, minority voters in covered jurisdictions continue to wait longer to vote compared to white voters and that increment reduces their turnout in small but potentially consequential amounts. We argue that dismantling Section 5 creates an environment where inconvenient voting requirements are now acceptable. Fundamentally, when citizens are not treated similarly with regard to democratic practices such as voting then the country’s democratic culture is threatened

Novel Methods for Fabricating All Solid State Lithium Ion Batteries

To further the advancement of safer, more cost effective lithium ion batteries, the effectiveness of all-solid-state lithium ion battery systems using LiCoO 2 sintered electrodes and LLTO solid state electrolyte was evaluated through electrochemical testing. The rapid advancement of power consumption by mobile devices and the high demand for more efficient electric vehicles calls for a novel battery with higher energy density, longer cycle life, and more dependable safety and construction. The research described here helps to advance the field of solid state lithium ion batteries and provides an avenue for future work and exploration

Genome sequence of canine herpesvirus

Canine herpesvirus is a widespread alphaherpesvirus that causes a fatal haemorrhagic disease of neonatal puppies. We have used high-throughput methods to determine the genome sequences of three viral strains (0194, V777 and V1154) isolated in the United Kingdom between 1985 and 2000. The sequences are very closely related to each other. The canine herpesvirus genome is estimated to be 125 kbp in size and consists of a unique long sequence (97.5 kbp) and a unique short sequence (7.7 kbp) that are each flanked by terminal and internal inverted repeats (38 bp and 10.0 kbp, respectively). The overall nucleotide composition is 31.6% G+C, which is the lowest among the completely sequenced alphaherpesviruses. The genome contains 76 open reading frames predicted to encode functional proteins, all of which have counterparts in other alphaherpesviruses. The availability of the sequences will facilitate future research on the diagnosis and treatment of canine herpesvirus-associated disease
