The estrangement between genetic scientists and theologians originating in the 1960s is reflected in novel combinations of human thought (subject) and genes (investigational object), paralleling each other through the universal process known in chaos theory as self‐similarity. The clash and recombination of genes and knowledge captures what Philip Hefner refers to as irony, one of four voices he suggests transmit the knowledge and arguments of the religion‐and‐science debate. When viewed along a tangent connecting irony to leadership, journal dissemination, and the activities of the “public intellectual” and the public at large, the sequence of voices is shown to resemble the passage of genetic information from DNA to mRNA, tRNA, and protein, and from cell nucleus to surrounding environment. In this light, Hefner's inquiry into the voices of Zygon is bound up with the very subject matter Zygon covers.  相似文献

It has been argued that natural language, in the form of inner speech, plays a central role in self-consciousness. However, it is not quite clear why. In this paper, we present a novel answer to the why question. According to the thesis presented in this paper, the brain as a physical system is limited in observing itself and relies on the mediation of natural language for the reconstruction of its phase space trajectory. Drawing on knowledge gathered on the measurement of dynamical systems, we detail the unique properties of natural language that may support this reconstruction.  相似文献

肿瘤组织是人类直接探讨肿瘤发生、发展和转移机制的研究对象,建立肿瘤组织库(tumor tissue bank,TTB),使用一套规范化操作程序(standard operating procedures,SOPs)来收集高质量的组织标本,避免其浪费势在必行。规范化TTB的建设也将涉及TTB的信息化管理及通用数据元素(common data elements,CDEs)的开发。深入探讨这些方面将有助于我国科研机构建立起自己标准化的TTB。  相似文献

This study examines the indirect role of psychological safety in shaping the four cognitions of psychological empowerment (i.e., meaning, competence, self-determination, impact) through three social mechanisms: authentic interactions, spiritual development, and perceived organizational voice. Data were collected from 229 congregation members of a nondenominational church. Preliminary analyses reveal psychological safety is: (a) linked to all four empowerment cognitions, (b) associated with the three proximal social mechanisms, and (c) indirectly predicts three of the four empowerment cognitions through heightened level of authentic interactions, spiritual development, and perceived organizational voice. Moreover, extraversion moderated the relationship of psychological safety with authentic interactions which, in turn, strengthened the size of the indirect effect for the meaning subcomponent of empowerment. Overall, this study suggests empowerment research can draw upon the potential, but frequently untapped, benefits of cultivating a secure space to facilitate member motivation through sincerity, personal development, and perceived voice.  相似文献

An emerging literature highlights the potential for broader dissemination of evidence‐based prevention programs in communities through existing state systems, such as the land grant university Extension outreach system and departments of public education and health (DOE–DPH). This exploratory study entailed surveying representatives of the national Extension system and DOE–DPH, to evaluate dissemination readiness factors, as part of a larger project on an evidence‐based program delivery model called PROSPER. In addition to assessing systems’ readiness factors, differences among US regions and comparative levels of readiness between state systems were evaluated. The Extension web‐based survey sample N was 958 and the DOE–DPH telephone survey N was 338, with response rates of 23 and 79 %, respectively. Extension survey results suggested only a moderate level of overall readiness nationally, with relatively higher perceived need for collaborative efforts and relatively lower perceived resource availability. There were significant regional differences on all factors, generally favoring the Northeast. Results from DOE–DPH surveys showed significantly higher levels for all readiness factors, compared with Extension systems. Overall, the findings present a mixed picture. Although there were clear challenges related to measuring readiness in complex systems, addressing currently limited dissemination resources, and devising strategies for optimizing readiness, all systems showed some readiness‐related strengths.  相似文献

The personality systems framework is a fieldwide outline for organizing the contemporary science of personality. I examine the theoretical impact of systems thinking on the discipline and, drawing on ideas from general systems theory, argue that personality psychologists understand individuals’ personalities by studying four topics: (a) personality’s definition, (b) personality’s parts (e.g., traits, schemas, etc.), (c) its organization and (d) development. This framework draws on theories from the field to create a global view of personality including its position and major areas of function. The global view gives rise to new theories such as personal intelligence—the idea that people guide themselves with a broad intelligence they use to reason about personalities.  相似文献

Implicit measures have become very popular in virtually all areas of basic and applied psychology. However, there are empirical and theoretical arguments that might raise doubts about their usefulness in research on political attitudes. Based on a review of relevant evidence, we argue that implicit measures can be useful to identify distal sources of political preferences in domains where self‐presentation may bias self‐reports (e.g., influence of racial attitudes on voting decisions). In addition, implicit measures of proximal political attitudes can contribute to the prediction of future political decisions by virtue of their capability to predict biases in the processing of decision‐relevant information (e.g., prediction of voting behavior of undecided voters). These conclusions are supported by research showing that implicit measures predict real‐world political behavior over and above explicit measures. The reviewed findings suggest that implicit measures may serve as a useful supplement to improve the prediction of election outcomes. Open questions and potential directions for future research are discussed.  相似文献

The Face-to-Face Still-Face (FFSF) paradigm allows to study the mother–infant dyad as a dynamic system coping with social stress perturbations. The State Space Grid (SSG) method is thought to depict both flexibility and stability of the dyad across perturbations, but previous SSG evidence for the FFSF is limited. The main aims were: (1) to investigate mother–infant dyadic flexibility and stability across the FFSF using the SSG; (2) to evaluate the influence of dyadic functioning during Play on infant Still-Face response and of infant stress response in affecting dyadic functioning during Reunion. Forty 4-month-old infants and their mothers were micro-analytically coded during a FFSF and eight SSG dyadic states were obtained. Dyadic flexibility and attractor states were assessed during Play and Reunion. Infants’ stress response was coded as negative engagement during the Still-Face episode. Two dyadic states, “maternal hetero-regulation” and “affective mismatch”, showed significant changes in the number of visits from Play to Reunion. During Play “maternal positive support to infant play” emerged as attractor state, whereas during Reunion a second attractor emerged, namely “affective mismatch”. Dyadic affective mismatch during Play correlated with infants’ negative engagement during Still-Face, whereas infants’ response to Still-Face resulted in minor social matching during Reunion. Findings provide new insights into the flexible, yet stable, functioning of the mother–infant dyad as a dynamic system. Evidence of a reciprocal influence between dyadic functioning and infant social stress response are discussed.  相似文献

一系列实验发现消费者多样化寻求行为随选择集增大而呈现倒U型变化,这是由于过大选择集情况下消费者倾向于采取启发式信息处理策略导致多样化寻求行为降低。同时,个体的认知需求水平调节选择集大小与多样化寻求行为间的倒U型关系。此外,通过操纵个体认知困难,理论机制进一步得到验证:在认知困难条件下,消费者也会因采用启发式信息处理策略而导致多样化寻求行为显著降低。  相似文献

To function well in an unpredictable environment using unreliable components, a system must have a high degree of robustness. Robustness is fundamental to biological systems and is an objective in the design of engineered systems such as airplane engines and buildings. Cognitive systems, like biological and engineered systems, exist within variable environments. This raises the question, how do cognitive systems achieve similarly high degrees of robustness? The aim of this study was to identify a set of mechanisms that enhance robustness in cognitive systems. We identify three mechanisms that enhance robustness in biological and engineered systems: system control, redundancy, and adaptability. After surveying the psychological literature for evidence of these mechanisms, we provide simulations illustrating how each contributes to robust cognition in a different psychological domain: psychomotor vigilance, semantic memory, and strategy selection. These simulations highlight features of a mathematical approach for quantifying robustness, and they provide concrete examples of mechanisms for robust cognition.  相似文献
