This chapter explores the question, posed by Svetlana Boym in The Future of Nostalgia, ‘How can one be homesick for a home that one never had?’ Its focus is Woody Allen’s 2011 film Midnight in Paris, the director’s most overt and sustained meditation on nostalgia, and the most wooing. The film concerns a twenty-first-century Hollywood screenwriter, Gil Pender, who stumbles effortlessly through the space-time continuum to find himself (in both senses) among Gertrude Stein’s Lost Generation, a world he has always believed to be his spiritual home. Through Gil’s time-travelling odyssey, Allen probes the allure and the perils of nostalgia; he shows how nostalgia relies on impossibility or absence to feed it, to lend it piquancy and artistic efficacy. The chapter also examines the Lost Generation’s propulsive nostalgia which was spawned by a tremendous sense of rootlessness and flux, and why the Odyssey was a guiding text for expatriates like Joyce, Hemingway, and Fitzgerald.

Block Universe

Heraclitus declares the being (that which exists, nature) but identifies it with becoming, but Parmenides declares just the Being; only what is, is, what is not, is not. All “follows” from that: change, he argues, is logically impossible and so what is, is one and unchangeable! This dazzling absolute monism is in daring disagreement with sense perception, but curiously it has found a well-known genius as a supporter. Emboldened by his theory of relativity, Einstein considers the universe as a four-dimensional “block” (a space-time continuum like a loaf of bread) which, remarkably, contains all moments of time (of past, present, and future) always, and where change is an illusion. He said, “For we convinced physicists, the distinction between past, present, and future is only an illusion, however persistent.” In the block universe, the past is not gone, it is present; and the future, like the present, is, well, present, too.

AbstractProxy signature and group signature are two basic cryptographic primitives. Due to their valuable characteristics, many schemes have been put forward independently and they have been applied in many practical scenarios up to the present. However, with the development of electronic commerce, many special requirements come into being. In this article, we put forward the concept of group–proxy signature, which integrates the merits of proxy signature and group signature for the first time. We also demonstrate how to apply our scheme to construct an electronic cash system. The space, time, and communication complexities of the relevant parameters and processing procedures are independent of group size. Our demonstration of the concrete group–proxy signature scheme shows that the concepts brought forward by us are sure to elicit much consideration in the future.

For the traditional data cleaning algorithms mainly fill up the data based on the space-time relevance in the data level, they are not suitable for RFID application scenarios with track information based on multi-logical areas. This paper proposed a track data filling algorithm based on movement recency by studying the characteristics of RFID track data. This algorithm maintains a track event tree according to the historical data, to predict the future data and guide the data cleaning. Also it considers the effect on the movement rules from time factor and brings in the ageing factor for maintaining the track event tree, which improved the predict accuracy of the tree and raise the veracity of the filling algorithm.

Temporal Focus

AbstractAccording to the Temporal Focus Hypothesis (TFH), people’s implicit spatial conceptions are shaped by their temporal focus. Whereas previous studies have demonstrated that people’s cultural or individual differences related to certain temporal focus may influence their spatializations of time, we focus on temporal landmarks as potential additional influences on people’s space-time mappings. In Experiment 1, we investigated how personally-related events influence students’ conceptions of time. The results showed that student examinees were more likely to think about time according to the past-in-front mapping, and student registrants, future-in-front mapping. Experiment 2 explored the influence of calendar markers and found that participants tested on the Chinese Spring Festival, a symbol of a fresh start, tended to conceptualize the future as in front of them, while those tested on the Tomb Sweeping Day, an opportunity to remember the ancestors, showed the reversed pattern. In Experiment 3, two scenarios representing past or future landmarks correspondingly were presented to participants. We found that past-focused/future -focused scenarios caused an increase in the rate of past-in-front/future-in-front responses respectively. Taken together, the results from these three studies suggest that people’s conceptions of time may vary according to temporal landmarks, which can be explained by the TFH.

The Future

Let S be a spacelike slice (defined formally in Section 2) in a space-time M. We will say that S is future causally complete in M if for each p ε J+(S) the closure in S of the set J-(p) ∩ S is compact. Define past causal completeness time-dually. Then S is causally complete if it is both future and past causally complete. A compact spacelike slice is necessarily causally complete, as is any Cauchy surface, but the concept of causal completeness is much broader than either of these two conditions. For example the slices t = const. ≠ 0 in the space-time obtained by removing the origin from Minkowski space are causally complete, although they are neither Cauchy nor compact. The slice t = 0 in the previous example and the hyperboloid in Minkowski space (where (t, x1, …, xn) are standard inertial coordinates) are examples of slices which are not causally complete. Physically speaking, an edgeless slice S is future causally complete if the information from S which reaches a point in the future of S comes from a finite nonsingular region in S. The Maximal Reissner-Nordstrom space-time is a well-known example in which this finiteness condition is not fulfilled by any of its asymptotically flat partial Cauchy surfaces. Indeed for any such partial Cauchy surface S, J-(p) ∩ S is non-compact for any p ε H+(S). However, as has been discussed in the literature (e.g. [17], p. 625 f), it is believed that the Cauchy horizon in this situation is unstable with respect to perturbations of the initial data on S.

Comparative Capitalisms

This review essay on the books New Directions in Comparative Capitalisms Research and The Future of Capitalism After the Financial Crisis uses the prism of ‘travelling theory’ to appraise whether both edited volumes meet their proclaimed aim to challenge the alleged reductionisms inherent in the Comparative Capitalisms (CC) research and reinvigorate the CC agenda's radical potential to analyse contemporary capitalism in critical and global perspectives. The verdict is affirmative as both volumes (i) introduce new as well as forgotten approaches to combined inter-spatial and inter-temporal comparisons into the CC literature, which then (ii) allows for the rediscovery of a multitude of roads to (knowledge about) really existing capitalisms. However, the essay urges some of the authors to avoid tracing capitalism only at its worst, which leads to an exaggerated intellectual pessimism and fatalism. Finally, putting both volumes into the context of post-socialist Central and Eastern European (CEE) capitalism, the review documents the continuing relevance of empirical discoveries in CEE for developing an expanded critical-global CC scholarship.
