自由飞行是未来空中交通管理系统的设计理念, 会影响管制员的飞行冲突探测绩效, 为其提供自动化的冲突告警是主要的应对思路。已有研究主要围绕冲突告警的通道类型、可靠性、提前呈现时间等单一属性展开, 发现冲突告警的通道类型、可靠性对管制员冲突探测绩效的影响与传统的自动化研究结果存在不一致之处。指出未来在实验中纳入冲突化解任务, 进行冲突告警多属性的整合研究, 有助于解释这些不一致之处、为冲突告警的设计提供更有效的指导。     

Using Social Representations Theory to Examine Lay Explanation of Contemporary Social Crises: The Case of Ireland's Recession

Social actors operate under a basic imperative to construct explanations for the events that surround them. Many issues that dominate the societal agenda today are not available to direct perception, derive from traditionally expert domains and are relatively remote from immediate local experience. This presents a challenge for lay explanation of these issues. Social representations theory offers a useful framework through which the construction of lay explanation for such issues can be examined. The current study recruited this theoretical framework to investigate lay explanations of the recent economic recession in Ireland. Data consisted of semi‐structured interviews with 14 members of the public and a web‐based survey (N = 138). The data suggested that explanations for the recession could be organised into three major themes: Power, Ordinary People and Fatalism. Strictly economic explanations were eschewed; instead, people drew upon a wide range of ideas about society, politics, morality, public spheres and personhood. The implications of these findings for understanding lay explanation of contemporary social crises are discussed. Copyright © 2011 John Wiley & Sons, Ltd.     

Risk perception,illusory superiority and personal responsibility during COVID-19: An experimental study of attitudes to staying home

Little is known about how different government communication strategies may systematically affect people’s attitudes to staying home or going out during the COVID-19 pandemic, nor how people perceive and process the risk of viral transmission in different scenarios. In this study, we report results from two experiments that examine the degree to which people’s attitudes regarding the permissibility of leaving one’s home are (1) sensitive to different levels of risk of viral transmission in specific scenarios, (2) sensitive to communication framings that are either imperative or that emphasize personal responsibility, or (3) creating ‘loopholes’ for themselves, enabling a more permissive approach to their own compliance. We find that the level of risk influences attitudes to going out, and that participants report less permissive attitudes to going out when prompted with messages framed in imperative terms, rather than messages emphasizing personal responsibility; for self-loopholes, we find no evidence that participants’ attitudes towards going out in specific scenarios are more permissive for themselves than for others. However, participants report they are more rigorous in staying home than others, which may cause moral licensing. Additionally, we find that age is negatively associated with permissive attitudes, and that male participants are more permissive to going out. Thus, during phases where it is important to promote staying home for all scenarios, including those perceived to be low-risk, imperative communication may be best suited to increase compliance.     

Inspire but don't interfere: Managerial influence as a double-edged sword for innovation

Managers play a pivotal role in the innovation process; yet, the mechanisms through which managers enhance or undermine innovation are not well understood. Drawing upon self-concordance theory, we argue that managers can augment employees' self-concordance—defined as the congruence of goals and actions with inner values and preferences—through transformational behavior and thereby contribute to innovation. However, transformational behavior is closely coupled to another form of influence, namely, process management, the attempt to directly manage innovation-related activities. This form of managerial influence reduces employees' self-concordance and thereby undermines innovation. We test our conceptual model in a sample of 188 innovation projects using a contextualized method that asked employees to assess their self-concordance and their managers' behavior during each project. Managers evaluated for each project the innovativeness of the outcome. Multilevel path-analysis provided support for our hypotheses. We discuss future research implications to disentangle innovation-facilitating and innovation-undermining facets of managerial influence.     

Young pedestrians' behaviours and risk perception: a pilot study with Italian early adolescents

This study aimed to investigate early adolescents’ mobility, taking into consideration risky pedestrian behaviours around roads and their relationship with independent mobility and risk perception in different traffic situations. The participants were 922 students, males (48%) and females, aged 10–14 and who attended the seventh (51%) and ninth grades in a medium-sized city in southern Italy. They completed an anonymous self-report questionnaire at school, specifically designed for the research. Measures included mode of transport, level of independent mobility, frequency of risky behaviours as a pedestrian and risk perception of these behaviours. Moreover, students were asked to evaluate the risk, their likely behaviour, and likely motives for risky behaviour in a specific traffic scenario concerning a risky road crossing shown on a video. Gender and age differences were taken into consideration, and relationships between risky behaviour as a pedestrian, level of independent mobility and different measures of risk perception (concerning both risk behaviour as a pedestrian and in the video scenario) were investigated. Results showed that risky behaviours while travelling as a pedestrian were more widespread among ninth grade students and those who were more independent. Moreover, a strong relationship between a greater involvement in risky pedestrian behaviours and lower risk perception and a greater tendency to justify risky behaviours were found in the students. Results suggested the implementation of a prevention programme in early adolescence to improve both risk perception in specific traffic situations and the awareness of motives of risky road behaviours.     

Evasive action characteristics of motorcycle riders towards occluded-surprise and expected pedestrians: A pedestrian mock-up study

Evasive action performance of motorcycle riders plays a vital role in the prevention of road crashes. In possible conflicting scenarios, motorcycle riders need to respond quickly and perform evasive actions successfully to prevent collisions with other vulnerable road users such as crossing pedestrians. To study the motorcycle rider behavior in conflicts with occluded and visible pedestrians, we designed four mock-up pedestrian scenarios, which includes, two surprise scenarios, one stationary scenario, and one expected scenario. Riders’ responses to the conflicts were measured using instrumented vehicle’s trajectory. Most riders preferred deceleration over swerving at the beginning of the interaction, followed by swerving at manageable speeds. Further, the analysis of riders’ deceleration rates revealed that a linear relationship existed between the deceleration rates and time to collisions (TTC). The study also analyzed the riders’ responses using repeated-measures analysis of variance (RM-ANOVA) to check for the effect of scenario type on deceleration rates. Results indicated that scenario type significantly affected the mean deceleration rates. Further, RM-ANOVA analysis carried out on the jerk behavior of motorcycle riders indicated that there was a significant effect of scenario type on the jerk behavior. Motorcycle riders’ jerks varied linearly with TTC and motorcyclists employ relatively higher decelerations and jerks when faced with pedestrians emerging suddenly from occluded locations such as from the blind spots formed due to parked vehicles. This study helps in understanding motorcycle rider behavior in critical situations and shows the need for assistive evasive systems for motorcycle riders to mitigate collisions with other vulnerable road users.     

国家内部地域文化差异及其对组织的影响

近年来,跨文化管理研究越来越关注国家内部（次国家层面）地域文化差异。在类似中国这样幅员辽阔历史悠久的多民族国家中,经济发展带来的人口流动和企业的跨地域布局使得员工与管理者都需要面对不同外部地域文化环境和组织内部人员地域多样化的挑战,研究国家内部地域文化差异及其对组织的影响有重要意义。 现有实证研究的一个重要共识是国家内部地域文化差异普遍存在于亚洲、欧洲和南北美洲各国。覆盖的国家类型多样,既有美国、巴西等地理跨度较大或有多民族多宗教历史文化背景的国家,也有日本、德国等地理跨度较小或历史上民族和信仰成分较单一的国家;既包括高度工业化的发达国家,也有发展中国家;既有集体主义倾向的东南亚和南美国家,也有个人主义倾向的北美和西欧国家。差异的内容主要包括霍夫斯泰德和施瓦茨的文化价值观维度,尤其是个人主义-集体主义。此外,不同国家之间内部地域文化差异的程度也显著不同。 聚焦中国大陆的研究主要关注了大陆地域文化区的划分和地域文化差异的内容维度。研究早期主要是从理论上根据影响文化的外部因素（如地理环境特征）讨论了文化差异的存在和文化区域划分,后来直接根据价值观相似度对不同省市或地区进行聚类;近年来,少数研究进一步依据多个指标综合划分地域文化区,并开始假设和验证不同区域价值观对个人和组织的影响。本文整合现有的几种中国大陆地域文化区划,用层次聚类法,获得了有较大共识的8个文化区。现有实证研究结果表明,中国大陆在集体主义、长期导向、风险偏好、儒家价值观等文化价值观维度存在地域差异。 有关国家内部地域文化差异如何影响组织行为和企业经营管理的实证文献仍然非常有限。 从跨地区文化比较的视角看,国家内部不同地区的文化价值观有可能影响当地人群的消费模式、员工行为、管理风格和决策（如投资）,进而影响企业生产效率和创新。从跨地区文化互动研究看,母公司企业文化与子公司所在地文化互动融合的模式有可能影响子公司经营绩效。最后,国家内部地域文化差异的程度不仅有可能影响本国企业跨地区布局的方式,还有可能影响企业跨境投资方式、企业国际化程度和经营绩效。 未来研究应更多的关注个人主义-集体主义以外的文化维度,探索主位视角来丰富研究理论和测量方法,尤其亟需更多对地域文化差异和跨地域互动在个人,团队和组织层面的结果的研究。最后,文化随着经济活动、政治变化、人口流动、对外交流互动而不断演化。在经济持续发展、商业活动地理布局不断拓展、人员流动极大增加、改革开放进一步深化的大背景下,我国大陆各区域及港澳台地区的地域文化价值观的演变,及其组织中不同层面的行为和结果的影响也值得探究。     

Élaboration d’une représentation des comportements contre-productifs dans les équipes dirigeantes d’organisations

Despite the important role top management teams play in the success of organizations, counterproductive behaviors taking place in those teams remain unrepresented in literature. This qualitative, inductive, and exploratory study aims to develop a representation of potentially harmful behavior to top management team functioning. Interview has been conducted with eight retreated top management team members. Following a thematic analysis, counterproductive behaviors were identified and organized in seven distinct patterns of behaviors. This study offers a representation of counterproductive behavior specific to top management teams, which was lacking in scientific and professional literature. Interventions from the top management teams’ leaders and consultants are discussed.     

中国内地大学生时间管理倾向的时代变迁：1999~2020

根据社会生态系统理论, 历时系统和宏观系统可能对个体时间管理倾向的发展具有重要意义, 但间接证据表明我国大学生时间管理倾向的发展趋势不明朗, 且相关研究缺乏从社会宏观视角的切入。基于此局限, 运用横断历史元分析的方法对1999到2020年间采用青少年时间管理倾向量表(ATMDI)的215篇文献进行分析(N = 103876)。结果发现：(1)我国大学生时间管理倾向水平总体呈缓慢下降趋势, 其中时间价值感保持稳定, 时间监控观和时间效能感呈下降趋势; (2)来自社会经济因素(GDP、居民消费水平、城镇化率)、就业因素(城镇登记失业率、普通高校毕业生人数)和网络因素(互联网普及率、网民每周互联网使用时长)的7项社会指标能显著预测大学生时间管理倾向的下降; (3)我国大学生时间管理倾向在性别和高校所在地上的差异不显著。研究结果为我国大学生时间管理倾向的时代变迁提供了证据支持, 从社会宏观因素的视角扩宽了大学生时间管理倾向的影响机制模型。     

社交媒体分享线索如何影响消费者的选择：印象管理与自主感缺失

随着社交媒体, 第三方消费点评网站及各类电商平台的蓬勃发展, 消费者能够越来越容易地与他人分享自己的消费和体验。为了适应这一迅猛的发展势头, 企业采取一系列措施加入社交媒体营销刺激消费者分享。如在产品界面添加分享按钮, 在各大社交平台添加主题标签, 或者直接使用带有分享刺激的广告口号。与以往研究关注消费者决策后的分享行为不同, 本研究提出社交媒体分享线索在消费者决策中发挥着重要作用, 影响消费者的判断与选择。具体来说, 本项目认为社交媒体分享线索一方面激发了消费者的印象管理动机, 另一方面也降低了自主感, 在此基础上探究了的两个行为决策结果：产品兴趣和决策终止。本项目具有重要的理论意义, 突破前人研究大多关注决策后分享的局限, 对现有社交媒体分享, 及数字环境如何影响消费行为是有益的补充。在实践上, 对企业如何更好地开展社会化媒体营销有着重要的指导意义。
