区块链技术应用于政府采购信用体系建设中的价值与路径

随着政府采购的深入发展，政府采购信用体系逐渐出现政府采购信誉减损、信用信息开放和共享程度较低、信用信息的安全威胁增加、信用监管效果不佳以及失信惩戒政策执行遭遇阻塞等问题。区块链技术应用于政府采购信用体系建设中有利于提供安全的信息环境、有利于多主体参与、有助于多中心协同、能促进信用监管多元化。区块链技术在政府采购信用体系建设中的应用路径:以区块链思维重新架构政府采购信用体系的信用管理基础；以“去中心化”的信任机制完善信用信息公开与共享平台；以分布式账本结构打造多主体监管参与机制；以智能合约机制实现信用评估智能化。     

The National Writing of Shiji (史记) and Sima Qian' s Community Consciousness of the Chinese Nation

《史记》民族书写体现出司马迁已初步产生了将天下各族视为一体的中华民族共同体意识,具体体现在创设少数民族专传的民族传记书写、主张少数民族与华夏族祖出一脉的民族同源书写、倡导和平处理民族纠纷的民族关系书写等三个方面.司马迁的中华民族共同体意识在两汉大一统格局的完成与巩固、家国一体与和合大同的儒家观念以及著家本人的著史意愿与品格三者的交互作用下生成,影响深远,促成了古代中国多民族友好大家庭的建构以及当代中国各民族大团结大融合局面的稳固.     

Predicting the Risk of Biological Invasions Using Environmental Similarity and Transport Network Connectedness

Understanding the risk of biological invasions associated with particular transport pathways and source regions is critical for implementing effective biosecurity management. This may require both a model for physical connectedness between regions, and a measure of environmental similarity, so as to quantify the potential for a species to be transported from a given region and to survive at a destination region. We present an analysis of integrated biosecurity risk into Australia, based on flights and shipping data from each global geopolitical region, and an adaptation of the “range bagging” method to determine environmental matching between regions. Here, we describe global patterns of environmental matching and highlight those regions with many physical connections. We classify patterns of global invasion risk (high to low) into Australian states and territories. We validate our analysis by comparison with global presence data for 844 phytophagous insect pest species, and produce a list of high‐risk species not previously known to be present in Australia. We determined that, of the insect pest species used for validation, the species most likely to be present in Australia were those also present in geopolitical regions with high transport connectivity to Australia, and those regions that were geographically close, and had similar environments.     

External knowledge search,absorptive capacity and radical innovation in high-technology firms

Open innovation and absorptive capacity are two concepts based on the idea that companies can leverage the knowledge generated externally to improve their innovation performance. The aim of this paper is to analyse the joint effect of open innovation and absorptive capacity on a firm's radical innovation. Open innovation is expressed in terms of external search breadth and depth strategies and absorptive capacity is described by distinguishing between potential and realized absorptive capacity. In order to test our hypotheses, we carried out empirical research in firms operating in high-technology industries. The results indicate that internal routines and processes for absorbing external knowledge help explain radical innovation as they show a significant effect of potential and realized absorptive capacity. Also, there is a moderating effect of absorptive capacity on open innovation. Specifically, potential absorptive capacity exerts a positive effect on the relationship between external search breadth and depth and radical innovation. Realized absorptive capacity moderates the influence of external search breadth. These findings confirm the complementary nature of absorptive capacity and open innovation search strategies on radical innovation.     

Managing the Risk of Aggressive Dog Behavior: Investigating the Influence of Owner Threat and Efficacy Perceptions

Aggressive behavior in pet dogs is a serious problem for dog owners across the globe, with bite injuries representing a serious risk to both people and other dogs. The effective management of aggressive behavior in dogs represents a challenging and controversial issue. Although positive reinforcement training methods are now considered to be the most effective and humane technique to manage the risk of aggression, punishment‐based methods continue to be used. Unfortunately, there has been little scientific study into the various factors influencing whether dog owners choose to use positive reinforcement techniques to manage aggression in their dogs. As such, current understanding of how best to encourage and support dog owners to use these methods remains extremely limited. This article uses a survey methodology based on protection motivation theory (PMT) to investigate the factors that influence owner use of positive reinforcement methods to manage aggressive behavior, in an attempt to understand potential barriers and drivers of use. In addition, the article provides an initial exploration of the potential role of wider psychological factors, including owner emotional state, social influence, and cognitive bias. Findings show that the perceived efficacy of positive reinforcement methods and the perceived ability of owners to effectively implement the technique are both key factors predicting future intentions and current reported use. Future interventions should focus on enhancing owner confidence in the effective use of positive reinforcement techniques across multiple scenarios, as well as helping owners manage their own emotional responses when they encounter challenging situations and setbacks.

论共同体观念的语词生成与理论建构

本文运用发生学的方法，揭示共同体观念的语词生成和共同体思想的理论建构。第一部分，作者指出，共同体这个语词在西方语言中源于共善和公共，具有丰富的内涵。第二部分，作者指出，共同体是古希腊罗马哲学和政治学的重要概念，在哲学形上学和伦理学的语境下，共同体与共善的关系密不可分;而在政治学的语境下，共同体是公共的名词化和实体化，共善则是建构人类社会的纲领和目标。把善提升为至善是一条哲学伦理学的理论建构通道，而把善提升为共善，则是哲学政治学的通道，与哲学伦理学的理论建构通道并行不悖。第三部分，作者指出，奥古斯丁批判地吸取了柏拉图和西塞罗的相关思想，然后以公义为纲，建构了他的理想共同体———上帝之城。奥古斯丁对共善的探究，直接导致对理想共同体的理论建构。他的理想共同体以信仰为核心，以伦理为共同体成员的守则，以秩序与和谐为共同体的特色，以普爱为共同体生存与发展的动力。
