再议规模经营中的粮食安全问题:争议回应与政策启示

在既定资源约束下实现粮食产出最大化是粮食生产安全的核心。而今旨在提升粮食竞争力的农业规模经营虽得到政府力推,却并非保障国家粮食安全的充分条件。在梳理规模经营与粮食安全保障相关争论的基础上,结合调研资料,依次回应了规模经营后农地是否大概率用于种粮、规模经营是否可持续以及规模经营能否保障粮食产量三个焦点问题。研究发现,与小农经营相比,规模经营与种植结构“非粮化”虽无必然联系,却存在规模经济不显著及单产提升乏力等问题。对此,一方面应强化小农扶持力度,巩固维系小农群体的粮食保障功能;另一方面应调整规模经营主体的政策干预结构,除非在规模经济与土地产出率不一致的情形下,应最大化避免对规模经营主体的直接干预,降低政策的扭曲效应,推动规模经济实现。     

Government Intervention in Public Sector Industrial Relations: Lessons from the Alberta Teachers’ Association

In the public sector, Canadian governments intervene frequently in labor disputes by suspending collective bargaining and curtailing legal strikes. Previous research has focused on the contours of government intervention, such as its overall effects on collective bargaining and strikes. The discussion highlights one actor, a government, restricting the behavior of another actor, a union, using legislation and policy making. As a result, we know less about more micro-level elements and implications of the process of government intervention. I address these themes using a detailed case study of the Alberta Teachers’ Association and the strikes it coordinated in 2002.

How publics react to situational and renewing organizational responses across crises: Examining SCCT and DOR in social-mediated crises

The prevalence of social media among networked publics calls for more research regarding how organizations can conduct effective crisis communication on social networking sites. Based on the situational crisis communication theory (SCCT) and the discourse of renewal (DOR) theory, this study examined how social media publics’ sentiments were affected by situational and renewing organizational responses in various clusters of crises. Twitter data of six crises representing three crisis clusters varying in the responsibility attribution (i.e., ambiguous, accidental, and preventable) were collected. We conducted a content analysis on organizations’ official tweets during crises (N = 59) and sentiment analysis on publics’ replies on Twitter (N = 4,340). The results showed that publics’ positive sentiments toward organizations were affected by organizational crisis responses that included instructing information, sympathy, systemic organizational learning, and effective organizational rhetoric. We recommend that crisis managers express sympathy toward publics as well as organizational learning that prevents a crisis from happening again.     

Narrative persuasion,identification, attitudes,and trustworthiness in crisis communication

The purpose of this study is to test the effects of narratives in crisis communication. This research assesses how organizations benefit from using stories in their media responses, relative to sharing nonnarrative information. The theory of crisis response narratives (Heath, 2004) holds that ethical narratives are effective because they enhance trustworthiness, attitudes toward the spokesperson, and identification with the spokesperson. Normative crisis communication theory exhorts disclosing truthful information rather than spinning. In an online experiment, participants (N = 365) watched a news interview in which a scandalized company’s spokesperson responded to a journalist’s questions with (a) ethical narratives, (b) unethical (spin) narratives, or (c) nonnarrative information. Multiple mediator modeling assessed identification with the spokesperson, attitudes toward the spokesperson, and perceived trustworthiness of the spokesperson. Results indicate ethical narratives are more effective than unethical narratives. However, nonnarrative information most effectively enhances trustworthiness and bolsters identification.     

Effective elements of care-physical activity initiatives for adults with a low socioeconomic status: A concept mapping study with health promotion experts

In care-physical activity (care-PA) initiatives, primary care and sports are combined to stimulate PA among adults at risk of lifestyle related diseases. Preliminary results from Dutch care-PA initiatives for adults with a low socioeconomic status (SES) indicate a decrease in participants’ body weight and an improved quality of life, however, the elements that make these initiatives successful are yet to be identified. In total, 19 Dutch health promotion experts participated in our concept mapping (CM) of the effective elements of care-PA initiatives for adults with a low SES. The experts identified 111 effective elements of these initiatives, which were grouped into 11 clusters, focusing on: 1) approaching participants within the care-PA initiative, 2) barriers experienced throughout the initiative, 3) long-term implementation, 4) customizing the care-PA initiative to the target population, 5) social support, 6) structure and guidance, 7) the professionals within the care-PA initiative, 8) the accessibility of the care-PA initiative, 9) targeted behaviour and progression, 10) recruitment and administration, and 11) intersectoral collaboration. CM was useful for creating a valuable overview of these effective elements. Our results could be used to improve the development and implementation of future care-PA initiatives for adults with a low SES.

公共政策价值合法性危机探析

公共政策价值指向是政策科学的元范畴,是理解与研究公共政策的阿基米德点。公共政策作为政治系统的输出,其自身蕴藏着社会共同的善(common good)、正义(公正)和效率三重价值向度和价值指归。然而,日常的政策活动往往隐藏着一定的政策价值合法性危机,作为政策价值危机的降解途径,善治、多中心公众参与和竞争性政策体制不失为降解乃至消解公共政策价值合法性危机的一剂良方。     

Underlying processes of SCCT: Mediating roles of preventability,blame, and trust

Despite the prevalence of the situational crisis communication theory (SCCT; Coombs, 2007) in crisis communication research, few SCCT-based studies have examined how different crisis types affect post-crisis reputation. This study, therefore, attempts to uncover the underlying processes of SCCT. Specifically, this study examined preventability, blame, and trust as potential mediators of crisis type and organizational post-crisis reputation. A between-subjects experimental study (crisis type: victim vs. accidental vs. preventable) was conducted with 329 college students. The results revealed that crisis type had no direct effects on reputation, but it did affect preventability, blame, and trust. More significantly, the results showed that crisis type indirectly affected reputation in two distinct ways: (1) via a sequence of preventability and blame and (2) via trust. The study includes a discussion of theoretical and practical implications.     

Crisis perceptions,relationship, and communicative behaviors of employees: Internal public segmentation approach

This study examines when and why employees engage in external communicative behaviors during the periods of a corporate crisis. Combining a cross-situational factor (i.e., pre-crisis relationship quality) and a situational factor (i.e., crisis-specific perceptions), this study segments internal publics to understand employees’ motivations of becoming advocates for or adversaries of their organization. The results of an online survey demonstrated that employees’ pre-crisis relationship to their organization plays a critical role in encouraging them to advocate for their company; meanwhile, their crisis-perception—whether they feel fewer constraints in solving a crisis—is more likely to make them share negative information externally. Segmented groups of employees with high levels of both relationship and activeness are most likely to engage in both positive and negative external communication behaviors. Theoretical and practical implications for public relations and internal crisis communication are suggested.
