Coding ethical behaviour: The challenges of biological weapons

Since 11 September 2001 and the anthrax attacks that followed in the US, public and policy concerns about the security threats posed by biological weapons have increased significantly. With this has come an expansion of those activities in civil society deemed as potential sites for applying security controls. This paper examines the assumptions and implications of national and international efforts in one such area: how a balance or integration can take place between security and openness in civilian biomedical research through devising professional codes of conduct for scientists. Future attempts to establish such codes must find a way of reconciling or at least addressing dilemmatic and tension-ridden issues about the appropriateness of research; a topic that raises fundamental questions about the position of science within society.     

行为科学在中国的回顾与前瞻——为悼念孙友余同志而作

过去因孙友余同志的倡导 ,行为科学曾在中国 80年代盛极一时 ,对管理实践与理论研究 ,都作出了许多成绩 ,并且成立了全国的行为科学学会 ,办了几期厂长经理的培训班 ,为我国的管理工作的科学化成为一种推动作用。后孙友余同志因病离职 ,行为科学学会名存实亡 ,现在已无全国的学会组织。因为下一世纪进入转型时期 ,行为科学在知识经济中的地位更加重要 ,因而提出恢复全国行为科学学会以开展工作 ,兼以此纪念孙友余同志的逝世。     

The man who listens to behavior: folk wisdom and behavior analysis from a real horse whisperer

The popular novel and movie The Horse Whisperer are based on the work of several real-life horse whisperers, the most famous of whom is Monty Roberts. Over the last 50 years, Roberts has developed a technique for training horses that is both more effective and less aversive than traditional training techniques. An analysis of Roberts' methods (as described in his book, The Man Who Listens to Horses) indicates a deep understanding of behavioral principles including positive reinforcement, timeout, species-specific defense reactions, “learned helplessness,” and the behavioral analysis of language. Roberts developed his theory and techniques on the basis of personal experience and folk wisdom, and not as the result of formal training in behavior analysis. Behavior analysts can clearly learn from such insightful yet “behaviorally incorrect” practitioners, just as such practitioners can benefit from the objective science of behavior analysts.     

What is the Thematic Structure of Science?

The paper justifies the concept of “thematic structure” or “order of knowledge” over the traditional “classification of sciences” due to the uncertainty of many classification criteria. The thematic structure of science has, of course, various levels and various dimensions. Arguments against any forms of separating the humanities from sciences in the traditional sense of the term are presented and discussed. Equally unacceptable are attempts at sharp separation of technical disciplines and humanities. The thematic structure of humanities is not created by some material aspects but rather through the interest — or problem-oriented aspects. In addition to the natural sciences and the humanities there exists an important sphere of sciences on artefacts or, using the term by H. Simon, the sciences of the artificial. For the contemporary research activities is typical what could be denoted as “interdisciplinary or multidisciplinary complex.” The paper traces a set of epistemological criteria for the justification of the relative independence of a scientific discipline.

SELECTIVE ASSOCIATIONS PRODUCED SOLELY WITH APPETITIVE CONTINGENCIES: THE STIMULUS-REINFORCER INTERACTION REVISITED

In studies reporting stimulus-reinforcer interactions in traditional conditioning paradigms, when a tone-light compound was associated with food the light gained stimulus control, but when the compound was paired with shock avoidance the tone gained control. However, the physical nature of the reinforcerrelated events (food vs. shock) presented in the presence of the tone-light compound was always confounded with the conditioned hedonic value of the compound's presence relative to its absence. When the compound was paired with shock, its presence was negative relative to its absence (which was shock-free). In contrast, when the compound was paired with food, its presence was positive relative to its absence (which was food-free). The present experiment dealt with this confounding effect by conditioning a tone-light compound to be positive or negative, relative to its absence, solely with food reinforcement. One group of rats received food for responding in the presence of the tone-light compound and no food in its absence. The other group also responded in the presence of the compound, but received food only in its absence. These rats were trained on a chained schedule in which responding in the presence of the tone-light compound produced a terminal link signaled by the absence of the compound; responding ceased in the terminal link because it delayed food delivery. In a test session to assess stimulus control by the elements of the compound, tone and light were presented separately under extinction conditions. Rats that had been exposed to a positive correlation between food and the compound emitted almost double the responses in the presence of the light as in the presence of the tone. In comparison, rats that had been exposed to a negative correlation emitted only two thirds as many responses in the presence of the light as in the presence of the tone. Because this selective association was produced using only food, it appears that the contingencies under which a reinforcer is presented, rather than (or as well as) its physical properties, can generate the selective associations previously attributed to “stimulus-reinforcer interactions.” This could mean that regardless of the class of reinforcer that ultimately maintains responding (appetitive or aversive), the contingency-generated hedonic value of the compound stimulus may influence the dominant modality of stimulus control.     

动、静态视觉信息在真实世界视觉搜索中的作用

真实环境中的视觉搜索是人和动物赖以生存的重要能力。目前的视觉搜索研究多使用静态的观察者和静止的二维搜索对象, 侧重于探究注意在搜索中的作用; 现有的视觉搜索理论模型主要概括了影响搜索的自上而下的注意因素, 而将自下而上影响因素简单归结为影像显著性, 然而在真实环境中, 观察者或搜索对象是可以运动的, 搜索时可利用的视觉信息包括动态光流和静态影像结构信息。已有的视觉识别研究发现这两种信息相结合可以使观察者准确持久地识别场景、事件和三维结构。在现有视觉搜索理论模型中引入两种视觉信息可以较好还原真实环境中的搜索任务。我们提出研究构想和实验方案,探究利用动、静态视觉信息的视觉搜索过程, 从而完善现有的视觉搜索模型。我们认为充分利用环境信息可以提高搜索效率, 且在视觉搜索训练和智能搜索设计等方面有重要的应用价值。     

Aviation with fraternal twin wings over the Asian context: Using nomothetic epistemic and narrative design paradigms in social psychology

The present study proposes the future trends of Asian social psychology by taking into account its possible contribution to broad cultural and historical contexts of Asia. First, I locate social psychology in a two (nomothetic vs narrative) by two (epistemic vs design) paradigm of sciences. Second, I propose that different research perspectives in social psychology (i.e. so-called mainstream and narrative-design social psychology) may be considered as fraternal twins of the same mother, classic social psychology, and describe where each of the twins is heading. Third, I introduce two modes of research activities, Mode I and Mode II, based on previous research, and examine each twin in both modes of research. Finally, I focus on the broad context of Asia and propose that we should expand two wings, especially, the second wing over the context of the region.     

FIRST PERSON PLURAL: SELF‐UNITY AND SELF‐MULTIPLICITY IN THEOLOGY'S DIALOGUE WITH PSYCHOLOGY

In contradistinction to the contemporary human sciences, recent theological accounts of the individual‐in‐relation continue to defend the concept of the singular continuous self. Consequently, theological anthropology and the human sciences seem to offer widely divergent accounts of the sense of self‐fragmentation that many believe pervades the modern world. There has been little constructive interdisciplinary conversation in this area. In this essay I address the damaging implications of this oversight and establish the necessary conditions for future dialogue. I have three primary objectives. First, I show how the notion of personal continuity acquires philosophical theological significance through its close association with the concept of personal particularity. Second, through a discussion of contemporary accounts of self‐multiplicity, I clarify the extent of theological anthropology's disagreement with the human sciences. Third, I draw upon narrative accounts of identity to suggest an alternative means of understanding the experiential continuity of personhood that maintains the tension between self‐plurality, unity, and particularity and thereby reconnects philosophical theological concerns with human‐scientific analyses of the human condition. Narrative approaches to personhood are ideally suited to this purpose, and, I suggest, offer an intriguing solution to understanding and resolving the problem of self‐fragmentation that has caused recent theological anthropology so much consternation.     

现代世界观中的意识及其哲学难题

人是具身心智的存在者,其存在方式独特性在于:他既依赖于物理形态的身体,又有存在论上不可还原性的主观性。因此如何在现代世界观中一致且完备地解释和理解人遂成了心智哲学的大问题。如果坚持现代世界观的基本立场一致性,那么对意识的解释和理解不可避免存在着"难问题"所界定的不完备性。人们大致从三个进路来处理不完备性的局面。然而,原则上它们都无法实现一致且完备的要求,因为这里存在一个根本的局限,即不可能通过认识论的方法在两种存在论形式(无和有)之间实现等价转换。尽管在认识论上这是一个悲观的结局,但另一方面它又是积极的,因为它显示了个体经验在存在论上是独一无二的。
