Researching a Local Heroin Market as a Complex Adaptive System

This project applies agent-based modeling (ABM) techniques to better understand the operation, organization, and structure of a local heroin market. The simulation detailed was developed using data from an 18-month ethnographic case study. The original research, collected in Denver, CO during the 1990s, represents the historic account of users and dealers who operated in the Larimer area heroin market. Working together, the authors studied the behaviors of customers, private dealers, street-sellers, brokers, and the police, reflecting the core elements pertaining to how the market operated. After evaluating the logical consistency between the data and agent behaviors, simulations scaled-up interactions to observe their aggregated outcomes. While the concept and findings from this study remain experimental, these methods represent a novel way in which to understand illicit drug markets and the dynamic adaptations and outcomes they generate. Extensions of this research perspective, as well as its strengths and limitations, are discussed.     

基于概念外延的用户认知表达-——以智能冰箱的用户认知研究为例

--用户认知具有主观性、模糊性、进化性及多维性等不确定性特点,难以编码与度量。提出以概念外延表达的集合论方法与模糊数学把研究用户认知转换成研究代表它的因素集合;提出用数据驱动的互联网文本挖掘获取因素集,采用TF-IDF与模糊统计求解因素的隶属度,完成用户认知的数学表达,为进一步研究提供数学基础;最后以海信智能冰箱项目进行论证。由于用户认知属于典型的不确定性复杂对象,论文所用方法适用于所有复杂对象的建模与求解。     

Role of Working Memory in Typically Developing Children’s Complex Sentence Comprehension

The influence of three mechanisms of working memory (phonological short-term memory (PSTM capacity), attentional resource control/allocation, and processing speed) on children's complex (and simple) sentence comprehension was investigated. Fifty two children (6-12 years) completed a nonword repetition task (indexing PSTM), concurrent verbal processing-storage task (indexing resource control/allocation), auditory-visual reaction time (RT) task (indexing processing speed), and a sentence comprehension task that included complex and simple sentences. Correlation and regression analyses were run to determine the association between the memory variables and sentence comprehension accuracy. Results revealed: (1) none of the memory variables correlated with simple sentence comprehension, (2) resource control/allocation and processing speed correlated significantly with complex sentence comprehension, even after covarying for age, and (3) attentional functioning and processing speed predicted complex sentence comprehension (after accounting for age). Results were interpreted to suggest that working memory is significantly involved in school age children's comprehension of familiar complex sentence structures.     

A logical expression of reasoning

A non-monotonic logic, the Logic of Plausible Reasoning (LPR), capable of coping with the demands of what we call complex reasoning, is introduced. It is argued that creative complex reasoning is the way of reasoning required in many instances of scientific thought, professional practice and common life decision taking. For managing the simultaneous consideration of multiple scenarios inherent in these activities, two new modalities, weak and strong plausibility, are introduced as part of the Logic of Plausible Deduction (LPD), a deductive logic specially designed to serve as the monotonic support for LPR. Axiomatics and semantics for LPD, together with a completeness proof, are provided. Once LPD has been given, LPR may be defined via a concept of extension over LPD. Although the construction of LPR extensions is first presented in standard style, for the sake of comparison with existing non-monotonic formalisms, alternative more elegant and intuitive ways for constructing non-monotonic LPR extensions are also given and proofs of their equivalence are presented.     

Space and time in psychoanalytic listening1

The analytic situation is by definition traumatic because it evokes hilflosigkeit, the state of helplessness of the newborn infant, which is the prototype of the traumatic situation, and at the origin of the experience of anxiety. The author addresses the chain of associations between the state of helplessness, repetition compulsion, trauma, infantile sexuality, pleasure and displeasure, which lie at the core of the transference experience, and which find their ultimate expression in the analyst's listening. The discovery of the compulsion to repeat instituted a paradigmatic shift in Freud's formulations, emphasizing the process of repetition of trauma, and instituting a link between the network of concepts indicated above. In the clinical example discussed, the author defines the psychoanalytic process by the primacy of sexuality, the erotic passivation in the transference that evokes the traumatic childhood sexual scene. Sexuality and sexual phantasies are at the centre of the elaboration of meaning. Furthermore, the author distinguishes between two types of interpretations, namely ‘open’ and ‘closed’.     

High‐Stakes Decision‐Making Within Complex Social Environments: A Computational Model of Belief Systems in the Arab Spring

People experiencing similar conditions may make different decisions, and their belief systems provide insight about these differences. An example of high‐stakes decision‐making within a complex social context is the Arab Spring, in which large numbers of people decided to protest and even larger numbers decided to stay at home. This study uses qualitative analyses of interview narratives and social media addressing individual decisions to develop a computational model tracing the cognitive decision‐making process. The model builds on work by Abelson and Carroll (1965), Schank and Abelson (1977), and Axelrod (1976) to systematically trace the inferences connecting beliefs to decisions. The findings show that protest decisions were often based on positive emotions such as pride, hope, courage, and solidarity, triggered by beliefs about successful protest and self‐sacrifice. By contrast, decisions to stay at home were triggered by beliefs about safety, state approval, and living conditions. As one participant said, “When I heard about the revolution in Tunisia, my heart was filled with solidarity for the people.” In the words of a non‐participant: “When people are killed, we must be careful. There are more important things than protest: safety and stability.” This study of individual explanations about events identifies the role of emotions in high‐stakes decision‐making within complex social environments.     

The Little Mermaid: Hans Christian Andersen's Feminine Identification

While verbally transmitted fairy tales express universal human concerns, the literary fairy tale, the written creation of an individual author, permits a psychodynamic understanding of the writer. The little mermaid's willingness to undergo the pain and mutilation involved in the loss of both her tail and was voice in order to become a mortal and marry a prince has been regarded as illustrating problems in female sexual development. However, a review of Hans Christian Andersen's biographical data indicates that the story also represents his unconscious homosexual conflicts and supports Freud's concept of the role of castration anxiety in the negative Oedipus complex.     

Bruno Bettelheim and the Chazon Ish: Toward a New Jewish Psychotherapy

Jeremiah is quoted and cited to show the basic optimism of Judaism. Why did Freud create an “Oedipus Complex,” rather than a “Joseph Phenomenon”?—especially since Freud had such a great knowledge of the Bible, including the Joseph story; and the Biblical Joseph made frequent appearances in Freud's dreams. Many of the advances in psychology and psychiatry were made in part as a rebellion against the ideology of psychoanalysis—this includes family therapy, behavioral therapy, and psychopharmacology. Bettelheim saw the shortcomings of psychoanalysis, both as a theory to explain human behavior and as a cure for psychological problems. The experiences of Bettelheim and of The Chazon Ish can give us new hope. The Chazon Ish and Bettelheim both sought to help in the context of a type of community. Reading of the Bible throws light on people's problems; and people can be helped by identification with Biblical characters. There is often specific advice in the Bible. Bible therapy can strengthen the bond between the therapist and the patient, which is important for patient improvement. There is a need for this type of psychotherapy.
