Human factors evaluation of an in-vehicle active traffic and demand management (ATDM) system

This research study focused on the evaluation of an emulated in-vehicle Active Traffic and Demand Management (ATDM) system on Interstate 66 in Northern Virginia. Traditional ATDM systems rely on infrastructure-mounted variable message signs (VMS) to provide information (speed limits, lane availability, etc.) to the traveling public. By providing information about dynamic roadway conditions on an in-vehicle device, the ATDM may improve driving safety and performance by allowing drivers to remain consistently aware of forthcoming traffic conditions and roadway requirements; even when external signage is inaccessible. This study represents an initial investigation of an emulated in-vehicle ATDM to provide developers with design guidance and ensure that unintended consequences, such as distraction, do not undermine the potential benefits.Twenty younger and 20 older participants, accompanied by a member of the research team, experienced the following ATDM features on an in-vehicle device (IVD) mounted to the dashboard: (1) dynamic speed limits, (2) dynamic lane use/shoulder control, (3) High Occupancy Vehicle (HOV) restrictions, and (4) roadway information from variable message signs. The IVD was equipped with auditory and visual alerts notifying the driver when relevant visual information was updated. Research questions addressed distraction and driver behavior associated with use of the system. Qualitative and quantitative participant data was acquired from the instrumented vehicle, various questionnaires, and researcher observation.Several key findings were uncovered: (1) The IVD, as tested, did not warrant classification as a source of distraction according to the NHTSA guidelines; v2) There was a significant difference in eye-glance durations to the IVD when comparing the VMS alerts to both the speed limit and lane management alerts; and (3) The speed limit alert motivated participants to alter their speed (per survey results and participant speed data).     

The moral basis of liberal education

The moral right to liberal education involves issues of distribution and of content. The former issue bears on the distribution of educational resources. The latter issue bears on the issue of multiculturalism. Both issues are discussed from the standpoint of equal rights.Presented as the first Distinguished Lecture to the Association for Philosophy of Education at its meeting in New York, 28 December 1991.     

The Endorsement of Minority Rights: The Role of Group Position, National Context, and Ideological Beliefs

The present research was conducted in the Netherlands and used an experimental design to examine the endorsement of minority rights among Turkish and Kurdish participants in two framed, national contexts: the Netherlands and Turkey. In the Dutch context, each group is a minority, whereas in the Turkish context the Kurds are an oppressed national minority and the Turks are the national majority. The results showed that the Turks were less in favor of minority rights in the Turkish context than in the Dutch context, whereas the Kurds were more in favor of minority rights in the Turkish than in the Dutch context. In addition, the endorsement of minority rights was related to beliefs about majority rule, state unity, and ingroup identification, as well as to cultural diversity and perceived pervasive discrimination. The associations with the former three measures differed between the two groups and the two national contexts, whereas the latter two measures had main effects on the endorsement of minority rights.     

Terrorist Suspect Religious Identity and Public Support for Harsh Interrogation and Detention Practices

Does the U.S. public's support for the use of harsh interrogation and detention practices against terrorism suspects depend upon the religious identity of the alleged perpetrators? Some scholarly research indicates greater public acceptance for abridging the rights of Muslims after 9/11. This is consistent with literature suggesting that heightened perception of threat decreases popular tolerance for racial, ethnic, and religious outgroups. This study executes a survey experiment and finds respondents to be more permissive of the use of extraordinary detention practices, such as indefinite detention and denying suspects access to legal counsel and civilian criminal courts, against terror suspects identified as Muslims. Furthermore, the study reveals that respondents are significantly less likely to treat domestic, right‐wing terrorist suspects with extraordinary detention, suggesting ingroup leniency.     

Generation Units and the Student Protest Movement in the United States: An Intra- and Intergenerational Analysis

The American student protest movement provides exceptional opportunities to observe how formative political experiences can affect intragenerational cleavages over the adult life span and how they may reflect on intergenerational continuities. Long-term national panel data from the high school class of 1965 and data from their parents and offspring are used here to exploit these opportunities. The results show that a sharp rift in political participation and attitudes emerged between protesters and non-protesters during the protest era, a rift that persists into mid-life and one that testifies to the conceptual utility of generation units. Continuities across the three lineage generations are demonstrated by the moderate similarities in the ideological and participative orientations that are associated with the protest status of the student generation.     

Real Objects Can Impede Conditional Reasoning but Augmented Objects Do Not

In this study, Knauff and Johnson‐Laird's (2002) visual impedance hypothesis (i.e., mental representations with irrelevant visual detail can impede reasoning) is applied to the domain of external representations and diagrammatic reasoning. We show that the use of real objects and augmented real (AR) objects can control human interpretation and reasoning about conditionals. As participants made inferences (e.g., an invalid one from "if P then Q" to "P"), they also moved objects corresponding to premises. Participants who moved real objects made more invalid inferences than those who moved AR objects and those who did not manipulate objects (there was no significant difference between the last two groups). Our results showed that real objects impeded conditional reasoning, but AR objects did not. These findings are explained by the fact that real objects may over‐specify a single state that exists, while AR objects suggest multiple possibilities.     

Victims' Stories: A Call to Care

In her book Victims' Stories and the Advancement of Human Rights, Diana Meyers offers a careful analysis of victims' stories as a narrative genre, and she argues that stories in this genre function as a call to care: they both depict a moral void and issue a moral demand, thereby fostering the development of a culture of human rights. This article, while finding Meyers's articulation of this idea compelling, questions Meyers's account of how victims' stories do their moral work. Whereas Meyers argues that victims' stories are complete narratives, characterized by a distinctive form of closure, it suggests that the moral power of victims' stories may lie in part in their open‐endedness or lack of closure. In telling their stories, victims engage their audiences in a new moral relationship and implicitly give them a role to play in bringing about the moral (and narrative) closure they seek.     

罗尔斯“分配的正义观”与诺齐克“持有的正义观”对照研究

分配正当性的根据是什么 ?人的基本权利与平等的要件如何分配才是符合正义的 ?罗尔斯和诺齐克从两个向度上对此作了深入研究。罗尔斯从平等的权利出发 ,主张用“公平正义的两个原则”来取代功利主义 ,认为除非有充足理由证明应当不平等 ,否则就应当平等。并要求依据“公平的正义原则”分配公共资源和自由体系 ;诺齐克从人的不可剥夺的权利出发 ,认为除非有充足理由证明应当平等 ,否则就应当不平等 ,通过“资格”理论确立“持有”的正当性。在功利主义、财产权、国家的作用、自由平等、分配模式和社会稳定的意义等方面 ,罗尔斯与诺齐克的观点也各有契合与对立。     

国民公正观的结构

对429名被调查者的研究发现,最为公众赞同的公正观依次为:(1)公正体现在法律面前人人平等;(2)公正体现为人们在求学、就业、投资、参政等方面的机会平等;(3)公正体现在程序公平合理。因素分析表明,国民的公正观是多元的,可分为6个维度,分别为权利、衡平、救济、报应、平等、平均。聚类分析的结果表明,公正内隐观的6个维度最终可聚为"均等"和"对等"2类。     

The Institute on Human Values in Medicine: Its Role and Influence in the Conception and Evolution of Bioethics

For ten years, 1971–1981, the Institute onHuman Values in Medicine (IHVM) played a keyrole in the development of Bioethics as afield. We have written this history andanalysis to bring to new generations ofBioethicists information about the developmentof their field within both the humanitiesdisciplines and the health professions. Thepioneers in medical humanities and ethics cametogether with medical professionals in thedecade of the 1960s. By the 1980s Bioethics wasa fully recognized discipline. We show the rolethat IHVM programs played in defining thefield, training faculty and helping schools todevelop programs. We review the beginnings ofthe IHVM in the crucible of social andtechnological change that led to theestablishment of the IHVM's parentorganization, the Society for Health and HumanValues. We then turn to the IHVM programsthrough which Faculty members receivedfellowships to explore new crossovers betweenthe humanities and the health professions. Wehave not only described the Fellows Program asit existed in 1973–1980, but have completed asurvey of the fellows a quarter of a centuryafter they held their fellowships. We describeother IHVM programs designed to facilitate theinitiation and development of new humanitiesprograms, to explore conceptual issues betweenmedicine and five humanities fields, to conductissue driven or educational method conferencesand to advance humanities programs intograduate education through the Directors ofMedical Education.
