A comparison of experienced and novice drivers’ rear-end collision avoidance maneuvers under urgent decelerating events

A leading vehicle’s sudden deceleration can lead to a rear-end collision. Due to a lack of driving experience, novice drivers have a greater tendency to be involved in these accidents. Most previous studies have examined driver response time and braking behaviors, but few researchers have focused on what experienced and novice drivers did after their feet touched the braking pedal and their hands turned the steering wheel. These braking and steering parameters are essential in understanding driver avoidance behavior during emergencies. We programmed rear-end crash risk scenarios to examine experienced and novice drivers’ behaviors thoroughly using a driving simulator. Twenty experienced and twenty five novice subjects participated in our experiments, and their braking and steering maneuvers were recorded when leading vehicles ran at 60 km/h, 80 km/h and 100 km/h. The results showed that the two groups of subjects tended to execute two kinds of maneuvers to avoid crashes: braking only (novice 33%, experienced 19%) and the combination of braking with steering (novice 22%, experienced 26%). When the novice drivers executed braking with steering, their response time and steering duration were significantly longer than those of the experienced drivers who executed braking with steering. As the speed increased, the novice drivers’ response time, maximum braking force and maximum steering angle were significantly affected. These results showed that novice drivers should brake only when the leading vehicle suddenly decelerates. The experienced drivers executed steadier maneuvers. Their risk perception time was shorter, and their maximum braking force and the maximum steering angles were smaller. The response time, braking intensity and steering wheel angle should be considered when developing rear-end collision warning systems.     

Theory as a Tool in the Social Scientific Study of Religion and Martin Riesebrodt's The Promise of Salvation

No single paradigm or debate currently orients the social scientific study of religion. Because of this, those engaged in the multidisciplinary study of religion find that a public conversation is often difficult. In this article and the Forum it introduces, we explore Martin Riesebrodt's recently published book, The Promise of Salvation: A Theory of Religion. Responding to the inadequacies of secularization paradigms, rational choice models, and postmodern criticism, Riesebrodt proposes an approach that ideal‐typically reconstructs the subjective meanings of institutionalized religious practices (liturgies). These subjective meanings center on the prevention and management of crises—social, natural, and bodily—through appeal and access to superhuman powers. This pragmatic emphasis on the superhuman defines religion as a distinct sphere of social action transhistorically and transculturally. Riesebrodt's theory creates new analytical possibilities, especially for understanding the modern resurgence of religion under conditions of secularization.     

中医“证概念”符号化的倡议与中医诊疗标量化的探讨

中医学是以“概念为单元”的功能医学,经络是功能网络。中医的“证”是外在的、变化着的、阶段性的。随着病的变化,证也在变化,质在变,量也在变。它有整体可控性,用模糊数学给中医的证候标量化,以便临床选方用药,“以数据治”。概念语言符号化,使中医古老的语形结构换上新衣,方便与当代科技沟通,进入网络传播,这或许是中医逐步走向现代化的一个切入点,一座桥梁。     

Intimate Distance: Rethinking the Unthought God in Christianity

The work of the French philosopher Jean-Luc Nancy shares with the thinkers of the ‘theological turn in phenomenology’ the programmatic desire to place the ‘theological’, in the broad sense of rethinking the religious traditions in our secular time, back on the agenda of critical thought. Like those advocating a theological turn in phenomenology, Nancy’s deconstructive approach to philosophical analysis aims to develop a new sensibility for the other, for transcendence, conceptualized as the non-apparent in the realm of appearing phenomena. This is why Nancy launches a project looking for the ‘unthought’ and unexpected within the Christian traditions, called deconstruction of Christianity. However, the deconstructive approach to the non-apparent differs fundamentally from that of the thinkers of the turn (1) in its being non-apologetic and non-restorative with regard to religion, because it starts from a problematization of the—typically modern, that is romantic—desire to defend and protect what would be ‘lost’ and possibly to restore this, (2) in its focus on the complex difference-at-work (différance) between religion and secularism, a difference that can be termed entanglement and complicity between these two, (3) in its hypothesis that this entanglement is essentially one between (the meaning and experience of, the rituality around) presence and absence in modern culture, (4) in its conviction that the philosophy and history of culture must join, support, complete and maybe even turn around phenomenology when dealing with the difficult task of determining what exactly would be ‘left’ of the ‘theological’ in our time. In this article, both positions are compared and confronted further, leading to an account of Nancy’s re-readings of the Christian legacy (its theology, doctrine, art, rituals etc.), and ending in a more detailed, exemplary inquiry into the tension between distance and proximity, characteristic of the Christian God.

心理学文化转向中的方法论难题及整合策略

近20多年来心理学的文化转向研究基本上扫清了许多外围障碍,但也暴露出了一些深层次的发展难题,如心理学的文化研究在实现科学观的转变过程中如何避免限制与泛化之问的矛盾：人类文化心理的普适性与差异性关系难以在实践操作层面上得到有效实现;后现代及全球化文化背景下加剧了心理学的对立与分歧。求得这一难题有效解决之关键在于改变滞后的科学观．深化阐述性与规范性心理文化层面研究的理论力度。     

Reinforcement of inhibition

A differential-reinforcement-of-other-behavior (DRO) schedule with trials and delayed reinforcement was investigated. Periodically a wheel was briefly available to rats, followed six seconds later by brief availability of a bar. Variable-ratio food reinforcement of wheel turns was adjusted to give 95% turns. After variable-ratio-five reinforcement of bar presses produced 100% pressing, then separate ratio schedules were used for presses following turns (turn presses) and presses following nonturns (nonturn presses). Increasing nonturn-press reinforcements decreased turns, even though total reinforcements increased. Reversal by decreasing nonturn-press reinforcements raised turns, though with hysteresis. Thus food reinforcement increased nonturns even though delayed six to ten seconds after nonturns, a delay that greatly reduces response reinforcement. Those and other results indicate that the turn decrease was not due to reinforcement of competing responses. Evidence against other alternatives, and the reduction of responding by increased reinforcement, indicate that the term inhibition is appropriate for the phenomenon reinforced. Response-specific inhibition appears appropriate for this particular kind, since its effects are more specific to particular responses than Pavlovian conditioned-inhibition. Response-specific inhibition seems best considered a behavioral output comparable to responses (e.g., both reinforcible) but with important properties different from responses (e.g., different reinforcement-delay gradients).     

Phrasal Unit Boundaries and Organization of Turns and Sequences in Korean Conversation

This paper examines an aspect of the grammar-interaction interface with respect to how participants orient to intra-turn phrasal unit boundaries as a locus that has interactional import for turn and sequence organization in Korean conversation. Phrasal unit boundaries in Korean serve as a space within a turn in which the speaker of the turn in-progress invites the recipient to acknowledge the speaker's point expressed up-to-that-point and collaboratively display his/her understanding thereof. In a sequentially and topically 'ripe' context, such unit boundaries often constitute places where more active participation on the part of the recipient is invited in the form of collaborative completion in which the recipient co-constructs the primary speaker's on-going turn. Phrasal unit boundaries also provide interactional resources which the speaker may exploit to sequentially delete out a problem in talk, e.g., by a sort of tying operation in which a subsequently added phrasal unit ties back to the speaker's previous utterance to the effect that the intervening talk containing a problem is canceled out by way of being shown to have been an interruption of the speaker's turn in-progress. This practice points to an aspect of the way in which the 'agglutinative' grammatical process involving the use of phrasal units shapes interactional patterns as observed in the course of organizing turns/sequences and managing problems in talk.     

There's a certain slant of light: Three attitudes toward the political turn in analytic philosophy

There has been a growing interest within analytic philosophy in addressing political and social issues, which has been referred to as the “political turn” in the discipline. The aim of this paper is twofold. First, it discusses the very characterization of the political turn. In particular, it introduces the definition proposed by Bordonaba-Plou, Fernández-Castro, and Torices, suggests that we should not consider the turn a form of activism, and explores an additional benefit of the ideal/nonideal distinction for characterizing the turn. Second, it addresses the concern of what attitude we should take in the face of the different sensitivities we might have with respect to what constitutes an injustice. Which philosophical works should count as part of the political turn? The paper explores three different attitudes toward this dilemma, and favors what it calls the revisionist attitude, which emphasizes the fact that our perception of injustice is subject to error.     

Exclusive preference develops less readily on concurrent ratio schedules with wheel-running than with sucrose reinforcement

Previous research suggested that allocation of responses on concurrent schedules of wheel‐running reinforcement was less sensitive to schedule differences than typically observed with more conventional reinforcers. To assess this possibility, 16 female Long Evans rats were exposed to concurrent FR FR schedules of reinforcement and the schedule value on one alternative was systematically increased. In one condition, the reinforcer on both alternatives was .1 ml of 7.5% sucrose solution; in the other, it was a 30‐s opportunity to run in a wheel. Results showed that the average ratio at which greater than 90% of responses were allocated to the unchanged alternative was higher with wheel‐running reinforcement. As the ratio requirement was initially increased, responding strongly shifted toward the unchanged alternative with sucrose, but not with wheel running. Instead, responding initially increased on both alternatives, then subsequently shifted toward the unchanged alternative. Furthermore, changeover responses as a percentage of total responses decreased with sucrose, but not wheel‐running reinforcement. Finally, for some animals, responding on the increasing ratio alternative decreased as the ratio requirement increased, but then stopped and did not decline with further increments. The implications of these results for theories of choice are discussed.
