Setting socially mediated engagement parameters: A topic modeling and text analytic approach to examining polarized discourses on Gillette’s campaign

Opinions on social and political issues can be easily polarized in socially mediated contexts. Using an inductive topic modeling and text analytical approach, the study analyzes more than 100,000 original tweets on polarized discussions on Gillette’s controversial campaign addressing toxic masculinity. Results suggest that influencers serve as ideological hyper-prototypes that attract significant attention equally from supporters and detractors, while hashtags and users’ reference of current events span the conversations across multiple contexts. Study results also indicate that horizontal information cascades from external ideologically centered sources that serve users’ identity and ideological signaling are a potential contributor of discourse polarization. Based on the study results, an identity- and representation-based approach to understanding socially mediated discourses is proposed, and four parameters of socially mediated engagement identified to further theorize engagement for public relations research in digital contexts.     

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.     

The Politics of Conversion: Religious Change,Materiality and Social Hierarchy in Central Upland Borneo

Contrary to the assumption that religious conversion is strongly influenced by the hegemony of global forces (colonialism and modern state formation) over local communities, this paper argues that internal class antagonisms and material conditions also play an important role in the dynamics of adoption of or resistance to Christianity. By taking narratives of inter-class contestation between aristocrats (paren) and commoners (panyin) and ritual changes among the Kayan-Kenyah in upland Central Borneo during periods of religious conversion, this paper shows the significance of social hierarchy on people’s decisions to change or retain their religious practices.     

动词复制句中的附加语控制

动词复制句（Verb－Copying Construction，VCC）是一种在汉语口语中经常使用的结构，用符号可以简单地表示为S＋VP1＋VP2，动词V2是动词V1的拷贝。这种结构本身具有独特的句法语义特征，也具有不同的句法变体。在其进行句法运算时，两个动词性结构首先独立运算，VP1作为附加语，VP2作为主句成分进入句法推导。通过附加语侧向移位、附加合并以及主题化特征核查等句法操作形成语言表达式。其句法变体的不同构型是因为不同的控制类型造成的。     

中国经济增长均衡与非均衡的转换机制——基于Markov机制转换自回归模型的实证分析

通过使用三状态三阶滞后的Markov机制转换自回归模型,笔者分析了1991年第1季度到2010年第1季度我国季度GDP增长的非线性特征,以及不同状态之间的转换机制问题。研究发现:1991年第1季度到2010年第1季度的中国季度GDP增长可以分为低增长状态、高增长状态和均衡增长状态三种情况;处于低增长状态和均衡增长状态的季度GDP增长率具有振荡收敛于其平均增长率的趋势,而处于高增长状态的季度GDP增长率具有振荡远离其平均增长率的趋势;低增长状态的平均持续期大约为46个季度,高增长状态的平均持续期为1个季度,均衡增长状态的平均持续期大约为3个季度。     

皈依与反叛——解读艾米莉·狄金森的宗教意识

艾米莉·狄金森诗歌的魅力在于文笔的简洁,字里行间流露出的思想更耐人寻味。从艾米莉.狄金森的思想世界入手,探讨艾米莉.狄金森的宗教意识。从她儿时的宗教氛围和宗教启蒙开始追溯,到她对宗教的思考、依赖和反抗,可以看出,无论在哪个阶段,不管上帝的形象在她心中是清晰的还是模糊的,诗人对上帝是皈依还是反叛,都对艾米莉.狄金森的宗教意识的形成进行了铺垫和产生了影响。     

Inventory model for convertible item with deterioration

Abstract

In this article, we developed a model for a convertible item (or product) where initial form of the item converts into another product by consuming conversion cost and time both. After duration, it converts again into a new product of a different nature. It is a sequential-type conversion from initial into two other products over states. The demand pattern and deterioration rate differ at each converted state. An inventory model is developed for such a kind of sequential convertible item. Expressions for total cost and other related costs (as per states) are derived and optimal time to convert the product in different states are calculated under model assumptions. A numerical example is incorporated in support of the theoretical findings and it validates the strength of the model.
