An analysis of “dignity”

The word dignity is frequently used both in clinical and philosophical discourse when referring to and describing the ideal conditions of the patient's treatment, particularly the dying patient. An exploration of the variety of meanings associated with the word dignity will note dignity's ambiguous usage and reveal instrumental concepts needed to better understand the discourse of the dying. When applied to a critique of recent and contemporary criticisms of the medical community's handling of the dying, such concepts might provide a more coherent notion of dignity. Rather than a separate construct, a death with dignity might be viewed as an interactive process among the dying and their caretakers. Together, this interdependent amalgam engages in humanizing communication aimed toward understanding the final needs and wants of the patient.     

Long-term rod dark adaptation in man. Threshold measurements, rhodopsin regeneration and allosteric sensitivity regulation. An evaluation

Recent evidence strongly suggests that the relationship between threshold elevation ( T ) and fraction of bleached rhodopsin ( B ), obtained during a major, middle period of long-term rod dark adaptation in man, is well described by a power function, i. e., T = k · Bⁿ , where k is a multiplicative constant and n is the exponent. Due primarily to the low reliability of measurements of rhodopsin regeneration, however, the exponent n of the power function cannot, at present, be given an exact value. Available information indicates that the value of the exponent ranges between 2.4 and 4. Implications of this uncertainty are discussed within the framework of the allosteric, tetrameric model of rod dark adaptation. It is concluded that this model in its simplest form may only offer a first approximation of the real system implicated in the process.     

THREE COMPARATIVE MAPS OF THE HUMAN

Abstract. This article is a response to the 1994 Star Island conference on the "Decade of the Brain" from a Jewish perspective. After a brief introduction about the logical function of models and maps, I compare and contrast three models of the human: Ezekiel's vision of the chariot in the Hebrew Scriptures, Franz Rosenzweig's geometry of the human face in Der Stern der Erlosung (the Star of Redemption), and a standard anatomical picture of the human brain. Whereas Rosenzweigs face is seen to be compatible with Ezekiel's chariot, both are seen to be radically distinct from the implicit conception of what a human being is in modern medical science. I conclude with a suggestion that the differences are to be understood in terms of their different intended functions and express my hope for some new kind of model that will incorporate the functional advantages of both.     

Integrating basic and applied research and the utility of Lattal and Perone's Handbook of research methods in human operant behavior

Lattal and Perone's Handbook of methods used in human operant research on behavioral processes will be a valuable resource for researchers who want to bridge laboratory developments with applied study. As a supplemental resource, investigators are also encouraged to examine the series of papers in the Journal of Applied Behavior Analysis that discuss basic research and its potential for application. Increased knowledge of behavioral processes in laboratory research could lead to innovative solutions to practical problems addressed by applied behavior analysts in the home, classroom, clinic, and community.     

Talking about race in a scientific context

There are at least two approaches that assist students in understanding complexity and differing interpretations about human diversity and race. Because differing perspectives emerge from data perceived at different levels, different scales provide a tool for understanding relationships among perspectives and understanding the differential importance of specific factors. Constructivist listening, which assists students in examining their own experiences, feelings and understanding, provides a tool for digesting complex new material and learning emotional literacy. It can be applied to dialogue about race and to classroom situations. These approaches can help students master the conceptual and interpersonal skills needed for successful scientific practice. This article was adapted from a presentation made at the “Communicating Science Conference” held at Hamilton College, Clinton, NY, October 1998.     

自动驾驶汽车与行人交互中的沟通界面设计：基于行人过街决策模型的评估

自动驾驶汽车要进入人车混行的普通道路, 需确保与过街行人之间的交互安全和效率。为解决这一问题, 高等级自动驾驶汽车往往在车辆外部装置显示设备, 即外部人机界面(eHMIs)以和行人沟通信息。在具体设计上, 已有研究主要采用文字、图形、投影等视觉沟通形式, 传达车辆状态(是否在自动驾驶模式)、意图和对行人的过街建议等沟通信息, 并在真实路段实验、虚拟场景及实验室实验等情境中评估了界面的使用对行人过街意向、速度和准确性等指标的影响。然而, 以行人为中心的外部界面设计需系统地支持行人过街决策前各阶段的信息加工需求。因此, 我们结合行人过街决策过程和情境意识理论, 提出行人与自动驾驶汽车交互中的动态过街决策模型, 从行人认知加工视角评估各种界面的沟通效果。评估的结果启示, eHMIs应促进行人对车辆信息的感知、理解和预测。在感知阶段, 应采用多种类型界面、多呈现载体相结合, 增强信息的可识别性。在理解阶段, 需结合文字说明、合理选择沟通视角、信号标准化和培训提高可理解性。在预测阶段, 应结合车辆内隐运动信息, 帮助行人快速准确获取车辆未来行动意图。更重要的是, 未来研究应关注在多行人、多车辆混行情境下的信息沟通设计及其对行人的影响。理论方面, 未来研究也需要关注外部界面如何通过自下而上的通路影响情境意识和心智模型的形成。     

社会排斥类型对求助行为意愿的影响

从心理需求威胁的视角切入,探讨不同类型的社会排斥对求助行为意愿的影响及其作用机理。两个实验研究的结果表明,相较于被忽略,被拒绝会促使人们在后续困境中产生更高的求助行为意愿。该效应产生的心理机制在于被拒绝会威胁归属需求,被忽略会威胁控制需求,而求助行为本身能够满足人们的归属需求,但同时会降低控制感,因此归属需求和控制需求在社会排斥类型对求助行为意愿的影响中均起着显著的中介作用。     

Scaling the Security Staircase

Building on the U.N. human security taxonomy of 1994, this article aims to explore the constructability of a reliable, valid, parsimonious, useful measure of human security that is relevant to contemporary environments and situations? A seminal 1994 U.N. report, Human Security in Theory and Practice, outlined seven types of human security (personal, health, food, community, economic, environmental, political). A quarter-century on, we added two more, cyber and national security, and tested if a single measure could capture all nine security concerns. A national sample of N = 1033 New Zealanders completed a brief online measure in which participants reported yes or no to experiencing each type of security and basic demographics. Guttman scaling placed these needs in an ascending order of difficulty. Analogous to a staircase, security may be scaled from personal up to political security (coefficient of reproducibility = .88), with three distinct but interrelated flights: (1) proximal (personal, health, food security); (2) social (cyber, community, economic, environmental); and (3) distal (national, political). We confirmed this nine-step, three-flight measure in our sample (Χ² = 81.72; df = 24; RMSEA = .048, 90%CI [.037, .06]; CFI = .976; TLI = .964; SRMR = .028). The measure showed configural, metric, scalar, and factorial invariances (across random-split subgroups). Ethnic groups and the precariously employed scored significantly differently, in coherent ways, on the security staircase scale.
