At the time, 1929, 1939, 1945 and 1968 all seemed important turning points in the track of our civilisation. By contrast, as anyone alive at the time will attest, 1955 seemed like an unexceptional year in the United States at least. Right in the middle of the ‘middle-of-the-road’ years of the Eisenhower presidency, 1955 hardly seemed like the year for a major aesthetic revolution. Yet it was in the brief span between 1954 and 1956 that the rock aesthetic displaced the jazz-based aesthetic in American popular music. Frank Sinatra, Tommy Dorsey, Patty Page, Perry Como, Nat King Cole, Tony Bennett, Kay Starr, Les Paul, Eddie Fisher, Jo Stafford, Frankie Lane, Johnnie Ray and Doris Day gave way on the popular music charts to Elvis Presley, Chuck Berry, The Platters, Bill Haley, Buddy Holly, Little Richard, Carl Perkins and the growing legion of rockers.

The purpose of this research is to propose and test a method for detecting intersections by analysing collectively acquired trajectories of moving vehicles. Instead of solely relying on the geometric features of the trajectories, such as heading changes, which may indicate turning points and consequently intersections, we extract semantic features of the trajectories in form of sequences of <i>stops</i> and <i>moves</i>. Under this spatiotemporal prism, the extracted semantic information which indicates where vehicles stop can reveal important locations, such as junctions. The advantage of the proposed approach in comparison with existing turning-points oriented approaches is that it can detect intersections even when not all the crossing road segments are sampled and therefore no turning points are observed in the trajectories. The challenge with this approach is that first of all, not all vehicles stop at the same location – thus, the stop-location is blurred along the direction of the road; this, secondly, leads to the effect that nearby junctions can induce similar stop-locations. As a first step, a density-based clustering is applied on the layer of stop observations and clusters of stop events are found. Representative points of the clusters are determined (one per cluster) and in a last step the existence of an intersection is clarified based on spatial relational cluster reasoning, with which less informative geospatial clusters, in terms of whether a junction exists and where its centre lies, are transformed in more informative ones. Relational reasoning criteria, based on the relative orientation of the clusters with their adjacent ones are discussed for making sense of the relation that connects them, and finally for forming groups of stop events that belong to the same junction.

Autobiographical Study

This article explores my journey from quantitative to qualitative researcher, including the effects this journey has had on my identity as well as on those whom I previously referred to as “subjects”. “Identity” is examined from both an historical as well as from a self-dialogical, autobiographical perspective. Eleven “twists” that mark turning points and detours describe this journey, and this paper employs “voices” that offer contextual background and contradictory advice on the road towards methodological identity. These twists describe experiences as both teacher and student and readers are invited to join in this retrospective reflection in order to experience insights and new appreciations. The article concludes with a brief integration of the literature and contextual reflection as well as several questions that invite readers to consider issues related to methodological identity and implications for teaching and learning that arose as a consequence of this journey.

Early one bright afternoon, seventeen centuries ago, Constantine stood staring at the sun. According to his self-appointed biographer Eusebius, Bishop of Caesarea, who claimed to have heard the story from Constantine himself, the emperor was on campaign, when, ‘around midday, as the day was declining’ he saw a shining cross of light over the sun, with the attached text ‘By this conquer’. The understandably startled ruler slept on the matter, whereupon Christ appeared in a dream and instructed him to fashion himself a copy of the holy sign, which would protect him against his enemies. He did as he had been told, took Christian clerics as his advisers and, not long afterwards, set off for Italy to fight his rival, Maxentius. The rhetorician Lactantius, writing about twenty years before Eusebius, presented a different tale in hisDe mortibus persecutorum: Constantine, on the eve of his decisive battle against Maxentius ina.d. 312, at the Milvian Bridge to the north of Rome, was instructed in a dream to ‘mark the heavenly sign of God’ on his shields. Constantine's moment of epiphany, sometimes equated with his ‘conversion’, has traditionally been seen both as one of history's great turning-points and as one of its most enduring enigmas. The interpretation of Constantine's vision(s) is further complicated by an anecdote that appears in an anonymous panegyric of the emperor, delivered ina.d. 310. Having turned off from the road to visit ‘the most beautiful temple in the world’, Constantine was greeted by a remarkable sight: ‘For you saw, I believe, Constantine, your Apollo, accompanied by Victory, offering you laurel crowns, which each brought an omen of thirty years [of life or rule]’.

The Way

In the triumvirate of personalities and motives—from Wright and Baldwin to Coates—we encounter the essential elements of the “crisis” that configures black passage in the New World. These lines of kinship, both consanguineous and ineffable, travelling from father to son, from uncle to nephew, from one generation to the next, lend us a figurative rhythm that grasps the notion of the processional—the traversal of time and space that remains fundamentally mysterious, just as we can put our finger directly on the problem—black life is still as endangered and precarious as it ever was. If one regards such passage as a “crisis,” then it is precisely because it is riddled with turning points, sudden ruts and rifts in the road when the way seemed smooth and clear—those moments when decisions must be made—and from that perspective, African-American cultural apprenticeship offers, by definition, crisis not as a state of exception, but rather, as a steady state, given historical pressures that bear in on it and that become, as a result, intramural pressures. What I wish to do in these remarks is to clarify one of the questions engendered by this predicament, and that is to say, the riddle of identity and how it matters, but even more than an inquiry into the identitarian, I am searching for a protocol through intramural space.
