Abstract

Purpose

The purpose of this study is to present the state of the art for fiber Bragg grating (FBG) acceleration sensing technologies from two aspects: the principle of the measurement dimension and the principle of the sensing configuration. Some commercial sensors have also been introduced and future work in this field has also been discussed. This paper could provide an important reference for the research community.

Design/methodology/approach

This review is to present the state of the art for FBG acceleration sensing technologies from two aspects: the principle of the measurement dimension (one-dimension and multi-dimension) and the principle of the sensing configuration (beam type, radial vibration type, axial vibration type and other composite structures).

Findings

The current research on developing FBG acceleration sensors is mainly focused on the sensing method, the construction and design of the elastic structure and the design of a new information detection method. This paper hypothesizes that in the future, the following research trends will be strengthened: common single-mode fiber grating of the low cost and high utilization rate; high sensitivity and strength special fiber grating; multi-core fiber grating for measuring single-parameter multi-dimensional information or multi-parameter information; demodulating equipment of low cost, small volume and high sampling frequency.

Originality/value

The principle of the measurement dimension and principle of the sensing configuration for FBG acceleration sensors have been introduced, which could provide an important reference for the research community.

Abstract

Purpose

Consumers tend to form their perceptions about a company via two associations: corporate ability (CA) that centers on expertise in producing quality products and corporate social responsibility (CSR) that focuses on societal obligations. To date, investigations on the adoption of such association-based corporate communication strategies are yet to address the interactive and multi-source features of social media. Drawing theoretical insights from corporate associations and the warranting principle, the purpose of this paper is to fill the gap and examine the joint effect of association-based corporate posting strategy and corresponding electronic word-of-mouth (eWOM) comment valence on social media.

Design/methodology/approach

A three (corporate posting strategy: CSR vs CA vs hybrid (CSR + CA)) by two (eWOM comment valence: positive vs negative) between-subjects experiment (n=193) was conducted.

Findings

The effect of corporate posting strategy on consumers’ CSR associations was found to be significant only when eWOM comment valence was positive. Significant main effects of both posting strategy and eWOM comment valence were found on CA associations, perceived corporate reputation, and purchase intention.

Originality/value

This study extends the theoretical framework of corporate associations to the interactive context on social media and provides empirical evidence for the effectiveness of association-based posting strategies when they are jointly presented with eWOM comments at different valence levels. Findings of this study also provide implications for business and communication professionals to communicate with consumers on social media more effectively.

Abstract

Purpose

The purpose of this paper is to adopt the uses and gratifications theory (Katz et al., 1974) to understand the phenomenon of relationship building on Facebook. In addition to company-related uses and gratifications, self-related uses and gratifications – expressing self-concept and seeking social interactions and entertainment – were identified. Company reputation and tribalism were incorporated in the theoretical model as underlying mechanisms to explain the effect of the company Facebook page usage on relationship building and engagement behaviors.

Design/methodology/approach

A survey was conducted in a Southeastern university in the USA with 459 college students. A three-phased model was proposed and analyzed using structural equational modeling.

Findings

The study results demonstrated that the use and gratification of expressing self-concept led to better perceptions of company tribalism and improved relational outcomes (trust and satisfaction). Company-related uses and gratifications, on the other hand, increased trust and satisfaction by increasing perceived company reputation. Satisfaction was found to significantly encourage individuals’ word-of-mouth activities about the company as well as Facebook engagement.

Originality/value

Although extensive research has been conducted on the topic of companies’ social media pages, most prior studies focused on company communication practices and strategies. This study explored this phenomenon from the public’s perspective regarding various usage motivations and patterns. Company tribalism, as a relatively new concept, was introduced to explain how expressing self-concept through companies’ social media pages could benefit relationship building and eventually result in engagement behaviors.

Abstract

Purpose

Narrative comments about dentists on physician review sites have been documented to increasingly influence people's selection of their dentists. From a communication standpoint, these comments are a type of narrative communication that people share their experiences with dentists by telling stories. Based on the frameworks of rhetoric structure theory and extended elaborated likelihood model, this study aimed to examine the effects of such storytelling from two perspectives including narrative structure and narrative focus.

Design/methodology/approach

A 4 (narrative structure) × 2 (narrative focus) between-subjects experiment was conducted to examine the proposed hypotheses and research questions

Findings

The results showed that a one-sided comprehensive comment focusing on technical competence generated the strongest persuasion effects measured by attitude and behavioral intention. These effects were mediated by perceived narrative credibility and enjoyment.

Originality/value

This study contributes to the extant literature in two ways. First, it extends previous studies of online narrative comments by showing which narrative structure and focus are deemed to be more persuasive when selecting a dentist. Second, it offers a test of two routes of information processing (i.e. cognitive and experiential) to understand the mechanism underlying the effects of narrative comments.

Abstract

Purpose

As the epidemic of online fake news is causing major concerns in contexts such as politics and public health, the current study aimed to elucidate the effect of certain “heuristic cues,” or key contextual features, which may increase belief in the credibility and the subsequent sharing of online fake news.

Design/methodology/approach

This study employed a 2 (news veracity: real vs fake) × 2 (social endorsements: low Facebook “likes” vs high Facebook “likes”) between-subjects experimental design (N = 239).

Findings

The analysis revealed that a high number of Facebook “likes” accompanying fake news increased the perceived credibility of the material compared to a low number of “likes.” In addition, the mediation results indicated that increased perceptions of news credibility may create a situation in which readers feel that it is necessary to cognitively elaborate on the information present in the news, and this active processing finally leads to sharing.

Practical implications

The results from this study help explicate what drives increased belief and sharing of fake news and can aid in refining interventions aimed at combating fake news for both communities and organizations.

Originality/value

The current study expands upon existing literature, linking the use of social endorsements to perceived credibility of fake news and information, and sheds light on the causal mechanisms through which people make the decision to share news articles on social media.

Abstract

Purpose

This paper studies the lateral stability regulation of intelligent electric vehicle (EV) based on model predictive control (MPC) algorithm.

Design/methodology/approach

Firstly, the bicycle model is adopted in the system modelling process. To improve the accuracy, the lateral stiffness of front and rear tire is estimated using the real-time yaw rate acceleration and lateral acceleration of the vehicle based on the vehicle dynamics. Then the constraint of input and output in the model predictive controller is designed. Soft constraints on the lateral speed of the vehicle are designed to guarantee the solved persistent feasibility and enforce the vehicle’s sideslip angle within a safety range.

Findings

The simulation results show that the proposed lateral stability controller based on the MPC algorithm can improve the handling and stability performance of the vehicle under complex working conditions.

Originality/value

The MPC schema and the objective function are established. The integrated active front steering/direct yaw moments control strategy is simultaneously adopted in the model. The vehicle’s sideslip angle is chosen as the constraint and is controlled in stable range. The online estimation of tire stiffness is performed. The vehicle’s lateral acceleration and the yaw rate acceleration are modelled into the two-degree-of-freedom equation to solve the tire cornering stiffness in real time. This can ensure the accuracy of model.

Abstract

Purpose

This study examines the effects of employees' personal social media posts on external publics' online engagement and offline word-of-mouth (WOM) intentions about a company. Specifically, it investigates how employee post characteristics including valence and content and employer reputation jointly influence publics' online and offline behaviors.

Design/methodology/approach

A 2 (post valence: positive vs. negative) × 2 (post content: organization-related vs. job-related) × 2 (employer reputation: good vs. bad) between-subjects experiment was conducted. Participants were asked to view a stimulus social media post created by a fictitious company employee, reflecting one of the eight experimental conditions on a random basis. After viewing, they were requested to report their online engagement intentions (i.e., “like,” “share” and “comment”) with the post and offline WOM intentions about the company.

Findings

The experimental results showed that participants expressed more “like” intentions when they viewed a positive post than a negative post. Further, they were more likely to “comment” on a job-related post as opposed to an organization-related post. In addition, a significant interaction effect between post valence and employer reputation on publics' online engagement was found, which in turn influenced their offline WOM intentions about the company.

Originality/value

This study is among the first empirical attempts to examine the effectiveness of employees' personal social media posts on external publics' online and offline behaviors. The experimental findings highlight the importance of managing employee relations from a corporate reputation perspective.

Abstract

Purpose

The purpose of this paper is to introduce an improved nearest‐neighbor collaborative filtering algorithm based on rough set theory to alleviate the sparsity problem of collaborative filtering. With experimentations, the new algorithm is thereafter evaluated.

Design/methodology/approach

Nearest‐neighbor algorithm is the earliest proposed and the main collaborative filtering recommendation algorithm, and its recommendation quality is seriously influenced by the sparsity of user ratings. By using rough set theory, the nearest‐neighbor collaborative filtering algorithm can be improved in the sparsity data situation. The union of user rating items is used as the basis of similarity computing among users, and then a rating predicting method based on rough set theory is proposed to estimate missing values in the union of user rating items for decreasing sparsity.

Findings

The sparsity problem of collaborative filtering can be alleviated by using the union of user rating items and estimating missing values based on rough set theory. The experimental results show that the new algorithm can efficiently improve recommendation quality of collaborative filtering.

Originality/value

The union of user rating items was used as the basis of similarity computing among users. A rating prediction method based on rough set theory with an assistant method was proposed to complete the missing values in the union of user rating items. Orthogonal list was used to storage user‐item ratings matrix.

Abstract

Purpose: Despite the significance of filial piety in intergenerational relationships and its important influence on parental health and well-being, few studies have explored the personal meaning of filial piety to older parents. This qualitative study aims to address this question.

Design: Responses to an open-ended question of “What makes a filial child in your view?” from a sample of 432 older parents in a rural Chinese county were collected face-to-face and analyzed using content analysis.

Findings: The personal meaning of filial piety varies. Seven broad themes emerged. These include widely persistent traditional filial piety beliefs (Be obedient, Respect, and Maintain frequent contact and show emotional care), filial piety values similar to filial obligations described in Western cultures (Help older parents when in times of need and Be a good citizen and take good care of themselves and their families), and traditional filial piety norms in the absolute form (Take care of every aspect of the parents’ life and Provide financial and material support to parents). Themes were also compared with dimensions of the intergenerational solidarity model.

Originality: Findings reflect the coexistence of traditional and modern filial values in relation to participants’ interpretation of filial piety, indicating that traditional filial piety beliefs are fading even in one of the least developed areas in China. Implications for interventions enhancing offspring’s filial performance are discussed.

Research limitations: Future studies on the understanding of filial piety from the perspective of offspring are warranted to draw a holistic picture of this topic.

The purpose of this paper is to consider the use and application of the “wire‐beam electrode” method to evaluate the effectiveness of corrosion inhibitors used in concrete.

Abstract

Purpose

The purpose of this paper is to consider the use and application of the “wire‐beam electrode” method to evaluate the effectiveness of corrosion inhibitors used in concrete.

Design/methodology/approach

The corrosion behavior of reinforcing bars in concrete was studied by simulating the 4×4 wire‐beam electrode array. Different inhibitors, such as NaNO2, NaNO2 + Na2CO3 and NaNO2 + aniline, were added to reinforced concrete. By measuring the open‐circuit potential of an iron wire, the impact of different inhibitors on the corrosion of rebar in the concretes was studied after immersion in 3 percent NaCl solution.

Findings

Best protection was achieved by adding NaNO2 and aniline as inhibitors jointly to the concrete, as this combination maintained the open‐circuit potential within the passivation range at all times, so ensuring the integrity of the passive membrane.

Originality/value

By addition of this combination of the inhibitors, the compactibility of the cement concrete structure can be increased, thereby protecting the reinforcing bar against the external corrosive media. It is a technical approach that can deliver long‐term protection of the steel, with the best practical and economic advantage.
