绩效与不足:成都会展业现状分析

近年,成都会展业发展迅速,多种会展经济形态得到全面发展,展览场馆数量较足,政府主导大型展会以及多层次的会展人才培养体系对会展业快速发展提供了必要的保障。然而,成都会展业仍然存在着品牌化和国际程度不高、场馆规模小和利用率较低、政府管理理念仍需创新、"产学研"结合不紧密等问题。本文通过分析当下成都会展业的绩效与不足,希望能为优化成都会展经济的产业结构、促进会展产业的转型和品牌升级提供有益的参考。     

民族地区特色小镇发展评价体系研究——广西中渡镇的实证

本文以民族地区特色小镇发展为目标层,针对其“重申报、轻发展”问题,选取环境资源、资本资源、基础设施、特色产业发展、政府支持和民生改善作为准则层,再细分为14个中间指标和45个执行指标,构建“目标层-准则层-指标层”评价体系。接着,运用模糊综合评价将这一评价体系应用于广西中渡镇。研究表明,中渡镇依托“一体两翼”资源,主推“旅游+”复合发展模式,特色产业亮点突出,但淡、旺季明显,特色产业效益有待提升,可优化游客结构和来源地,打造一体化“旅游带”,提振区域知名度。民族地区特色小镇发展评价体系的应用,要强化特色,避免同质性发展,结合政策优势构建更“接地气”的评价体系。     

稀土对水生生物的作用效应

研究了稀土对３种水生动物的毒性及对浮游植物光合作用产氧的影响。结果表明：水蚯蚓、枝角类的４８ｈ中间忍受限度（ＴＬｍ）值分别为４６４８ｍｇ／Ｌ和１３３６ｍｇ／Ｌ,安全浓度分别为１１０８ｍｇ／Ｌ和３０８ｍｇ／Ｌ。鳙乌仔在１５５ｍｇ／Ｌ浓度时,９６ｈ全部存活。稀土还有明显的促进浮游植物光合产氧的作用,水中喷洒１２ｍｇ／Ｌ的稀土可提高光合产氧量４６０８％。     

侨乡研究:对华侨、华人与中国关系的不同解读

在对华侨、华人的研究中,华侨、华人与中国的关系一直是基本的出发点和主要的关注点。在考察华侨、华人与中国的关系时,侨乡是考察和理解华侨、华人“特殊性”的一个重要方面和参照坐标。这不仅因为侨乡是华侨、华人与中国进行经济合作的主要区域,是海外移民影响祖籍地社会、文化的“独特风景线”,还因为侨乡研究是透视华侨、华人与中国关系的实证性研究。①虽然海外移民并非中国特有的现象,但侨乡却是具有中国特色的海外移民的产物。一、侨乡的“特殊”意义:正、反两方面的解读华侨、华人与中国的关系属于移民与移出地的关系,是一种互动的…     

Benevolence-dominant,authoritarianism-dominant,and classical paternalistic leadership: Testing their relationships with subordinate performance

We propose a new typology of paternalistic leadership styles based on how leaders demonstrate authoritarianism and benevolence, the two essential components of this type of leadership. Benevolence-dominant paternalistic leadership refers to leaders' sole dependence on the use of benevolence without their strong assertion of authority, whereas authoritarianism-dominant paternalistic leadership is based mainly on authoritarianism itself; classical paternalistic leadership, which best fits early observations of paternalistic leaders, refers to the salient combination of both leadership components. We used two distinct samples and methods to test this typology and the association with subordinate performance. Across the two studies, a field investigation with Taiwanese military supervisor-subordinate dyads and a hypothetical scenario experiment with U.S. working adults, we found a positive relationship between classical paternalistic leadership and subordinate performance as strong as that between benevolence-dominant paternalistic leadership and performance. Our findings echo the phenomenon that paternalistic leaders tend to combine benevolence with authoritarianism to affect subordinate performance.     

A continuous characterization of the maximum vertex-weighted clique in hypergraphs

For a simple graph G on n vertices with adjacency matrix A, Motzkin and Strauss established a remarkable connection between the clique number and the global maximum value of the quadratic programm: \(\textit{max}\{ \mathbf {x}^T A \mathbf {x}\}\) on the standard simplex: \(\{\sum _{i=1}^{n} x_i =1, x_i \ge 0 \}\). In Gibbons et al. (Math Oper Res 122:754–768, 1997), an extension of the Motzkin–Straus formulation was provided for the vertex-weighted clique number of a graph. In this paper, we provide a continuous characterization of the maximum vertex-weighted clique problem for vertex-weighted uniform hypergraphs.     

五河民歌的传承机制研究

民歌作为劳动人民最直接、最本真的情感表达和文化传承方式之一,其内在的传承机制是它能穿越历史传承至今的重要因素。通过对当下仍然存活在五河区域的五河民歌的实地考察,及对具有代表性的五河民歌的本体分析,试图找到五河民歌在传承和发展过程中所体现出的内在轨迹。     

Examining multiplicity and dynamics of publics’ crisis narratives with large-scale Twitter data

The new reality of networked publics on social media calls for crisis communication practitioners and researchers to understand the narratives generated by publics on social media during organizational crises. As social media publics possess diverse, unique characteristics and communicative needs during a crisis, they form interpretative communities and co-create various symbolic interpretations of the crisis. Extending the public-centric and narrative perspective to the context of social media crises, we examined what crisis narratives were constructed by social media publics (i.e., multiplicity) and how these narratives changed by crisis stages (i.e., dynamics). Using topic modelling based on large-scale Twitter data of the Chipotle E. coli crisis (N?=?40,610), we identified ten narratives subsumed under two themes (i.e., sharing-based and conversation-based) based on publics’ social constructions of their perceived risks and crisis experience. On the one hand, sharing-based narratives, heavily impacted by publics’ shared media coverage, reflected media crisis narratives and salient risk perceptions aligning with the news agenda. On the other hand, conversation-based narratives, fueled by publics’ opinion expression and emotional venting, demonstrated publics’ interpretations of their experience with the organization in the crisis with less salient but more diversified risk perceptions. Crisis managers are recommended to produce and deliver compelling narratives resonating with different groups of social media publics during crises.
