Abstract
Purpose
In this paper, Yale model was adopted to understand how the characteristics of a green message (goal framing, argument volume and argument consistency), its source (source credibility) and its receivers (environmental consciousness) influence the communication process regarding the receivers' perceptions and attitudes (information value, persuasiveness and communication effectiveness) and their intention to spread the green message.
Design/methodology/approach
Eight scenarios of factorial design were developed to test the effects of a message on receivers' perceptions and attitudes. 1,157 valid questionnaires were used to conduct AMOS-SEM and ANOVA analyses.
Findings
The analytical results showed significant differences between the persuasive effects of Scenarios 1 and 8. A high level of environmental consciousness significantly affected the relationships between the message characteristics, source credibility and information value, leading to a higher intention to share the green messages.
Research limitations/implications
The Yale model was applied to online persuasion to examine the receivers' perceptions of and attitudes toward a green message and their intention to share it on social networking sites (SNSs). Being environmentally conscious can strengthen the perception that the receivers of an online green message have of the source credibility and information value. The Yale model proved to represent the online green message-sharing context and explain how to persuade online users more effectively.
Practical implications
This study suggests that green message providers should present content emphasizing the losses associated with inaction, thus increasing the receivers' acceptance of the message's persuasiveness. Additionally, with the assistance of supportive measures, such as national education programs, government policies and actions showing corporate social responsibility, the environmental awareness of individuals can encourage them to share green message posts on SNSs and engage in green practices.
Social implications
A significant effect of the message characteristics (goal framing × argument volume × argument consistency) was observed on SNS users' perceived source credibility and information value. Therefore, key opinion leaders, governments, and organizations who want to promote green ideas and attract public attention are encouraged to provide messages emphasizing the costs of inaction and contain arguments with a sufficient number of responses strongly supporting the original message. This could arouse the concern for green issues among online communities.
Originality/value
A Yale model research framework was developed to investigate the effect of message characteristics on the intention to share green messages online. Receivers' environmental consciousness played a vital role in this message-sharing process.

Abstract
Purpose
The purpose of this paper is to present a K-band modified hairpin bandpass filter on a planar circuit with harmonic suppression and compact size.
Design/methodology/approach
The inter-connect transmission lines of conventional hairpin filter are replayed by T-shaped open stub to achieve transmission zero for second harmonic. This filter is simulated and optimized by using electromagnetic simulation software and tested on-chip.
Findings
This proposed filter shows the return loss of better than −10dB, the insertion loss of better than 2 dB in pass-band and suppression of more than 40 dB at second harmonic.
Originality/value
The proposed filter can be designed on monolithic microwave integrated circuit, PCB or LTCC and it is useable for microwave and microwave and millimeter-wave systems.

Abstract
Purpose
This paper aims to propose and verify an improved cascade active disturbance rejection control (ADRC) scheme based on output redefinition for hypersonic vehicles (HSVs) with nonminimum phase characteristic and model uncertainties.
Design/methodology/approach
To handle the nonminimum phase characteristic, a tuning factor stabilizing internal dynamics is introduced to redefine the system output states; its effective range is determined by analyzing Byrnes–Isidori normalized form of the redefined system. The extended state observers (ESOs) are used to estimate the uncertainties, which include matched and mismatched items in the system. The controller compensates observations in real time and appends integral terms to improve robustness against the estimation errors of ESOs.
Findings
Theoretical and simulation results show that the stability of internal dynamics is guaranteed by the tuning factor and the tracking errors of external commands are globally asymptotically stable.
Practical implications
The control scheme in this paper is expected to generate a reliable way for dealing with nonminimum phase characteristic and model uncertainties of HSVs.
Originality/value
In the framework of ADRC, a concise form of redefined outputs is proposed, in which the tuning factor performs a decisive role in stabilizing the internal dynamics of HSVs. By introducing an integral term into the cascade ADRC scheme, the compensation accuracy of matched and mismatched disturbances is improved.

Abstract
Purpose
Despite being a significant public health problem, teen dating violence and related risk behaviors are yet to be examined in Nicaragua. This study aims to examine the prevalence of in-person dating violence and cyber dating abuse and to test the associations between teen dating violence and substance use (i.e. alcohol, cigarette, marijuana and e-cigarette) as well as externalizing behaviors.
Design/methodology/approach
Survey responses were collected from a school-based sample of 1,799 Nicaraguan early adolescents (average age = 13.04 years).
Findings
The prevalence was 41% for in-person dating violence victimization, 39% for in-person dating violence perpetration, 30% for cyber dating abuse victimization and 26% for cyber dating abuse perpetration. The majority (56%) of the adolescents reported engagement in externalizing behaviors, but substance use prevalence was relatively low, ranging from 1–9% depending on the substance type. Multivariate regression analyses suggest that in-person dating violence perpetration was positively associated with all types of substance use and externalizing behaviors, while victimization was only associated with externalizing behaviors.
Originality/value
Despite the descriptive nature, the study is the first to examine the prevalence of teen dating violence and its relationships with other risk behaviors in Nicaraguan adolescents and have important health implications.

Abstract
Purpose
Communication plays an important role in health decisions and behaviors. Friends and family exert influence through communication and, when considering smoking, this is particularly salient among those friends and family who smoke. Guided by primary socialization theory and integrated behavioral model, the present study examined the effects of having smoking friends and family on smoking beliefs (e.g. negative consequences, positive reinforcement and negative reinforcement), cultural normative beliefs, pro-smoking injunctive norms, smoking intentions and recent smoking behaviors.
Design/methodology/approach
Cross-sectional online survey data were collected from college students (N = 227). Multivariate analysis of covariance and path analysis were performed.
Findings
College students who reported having smoking friends were more likely to report higher levels of positive reinforcement, cultural normative beliefs, pro-smoking injunctive norms, positive attitudes, smoking intentions and recent smoking behaviors than those without smoking friends. Frequent communication with smoking friends was significantly related to cultural normative beliefs, pro-smoking injunctive norms, positive attitudes and smoking intentions. The analysis, however, did not yield statistical support for the associations between frequent communication with smoking family and smoking perceptions, norms and behaviors.
Originality/value
The present study highlights the vital roles of friends' influence for college students' smoking behaviors. Communication-based intervention can help better equip college students with communication strategies that prevent tobacco use by promoting more effective conversations with friends.

Abstract
Purpose
The current study identifies successes and limitations of sustaining Dale se Real (DsR) as a school-based educational intervention program related to drugs and violence for 7th and 8th grade students in Nicaragua, Central America. As evidence-based interventions are transported and imported across national borders, issues surrounding their adaptation and sustainability become important targets for investigation.
Design/methodology/approach
Interviews were conducted with nine key informants (e.g. school directors, implementers) from seven institutions, four of which sustained DsR and three of which did not. This study explores DsR's fit with the institutions' missions and routines, program adaptability, broader community support and sustainability planning.
Findings
Findings demonstrate two emerging views of sustainability within the Nicaraguan schools: a deficit approach and an empowerment approach. These two approaches imply different motivational structures for institutions and also led to the practical finding that developers and trainers need to provide structured or formal ways of empowering schools to continue implementing a program after staff no longer routinely contact them.
Originality/value
This study contributes a particular case on what facilitates and impedes sustainability of school-based interventions that can inform future intervention research in Latin American countries.

This paper aims to address the spacecraft attitude regulation problem in the presence of extrinsic disturbances and actuator faults.
Abstract
Purpose
This paper aims to address the spacecraft attitude regulation problem in the presence of extrinsic disturbances and actuator faults.
Design/methodology/approach
Based on adaptive backstepping design technique, a new concise adaptive dual-mode control scheme is proposed, which can either use the fault information detected by fault diagnosis mechanisms or switch to the fault-unknown mode when the fault diagnosis information is non-existent for control signal generation. These two modes share an adaptive mechanism that reduces the complexity of the algorithm.
Findings
The new fault-tolerant attitude control algorithm can accommodate both modes with and without fault diagnosis mechanisms.
Originality/value
The proposed algorithm in this paper can be applied to both cases when the attitude control system is equipped with or without fault diagnosis capability. This also enhances the robustness of attitude control algorithm. This study performs numerical simulations and verifies that the algorithm could effectively adapt to both modes.

This study aims to examine whether the disclosure tone in earnings announcements is related to a firm’s corporate social responsibility (CSR) performance.
Abstract
Purpose
This study aims to examine whether the disclosure tone in earnings announcements is related to a firm’s corporate social responsibility (CSR) performance.
Design/methodology/approach
Considering the lower likelihood of earnings management conducted by CSR-conscious firms, and the significant market impact of the tone of disclosure in the earnings announcements, the study investigates whether firms with good CSR performance attempt to influence investors’ judgements through “soft information” and, thus, produce earnings announcements with more positive tone. Specifically, it examines whether CSR performance is positively related to the optimistic disclosure tone in earnings announcements.
Findings
The study finds that more socially responsible firms exhibit a more optimistic tone in earnings announcements. The findings are robust to a variety of sensitivity tests and data from different years. Furthermore, the study finds that the positive association between CSR performance and disclosure tone in the earnings announcement is particularly apparent in the manufacturing industry.
Research limitations/implications
This study contributes to the literature in multiple ways.
Practical implications
These findings should assist regulators in better understanding the verbal components in earnings announcements.
Social implications
It is possible that firms might opportunistically engage in CSR activities to enhance their social image to exaggerate financial performance and influence investors’ 2019 decisions.
Originality/value
These results show that CSR performance is positively associated with the optimistic tone in earnings announcements. The findings are consistent with two alternative interpretations. First, even though CSR-conscious firms are unlikely to engage in earnings management, they may engage a more subtle form of impressions/tone management. Second, firms with better CSR performance may have better financial performance, and thus are more confident and optimistic, resulting in a more positive tone in their earnings announcements. As the study controls for financial performance and find a positive relation between CSR concerns and optimism in earnings announcements, it favors the previous explanation.

Abstract
Purpose
This study investigates the impact of supply chain governance (SCG, which includes relational governance and contractual governance) on supply chain resilience (SCR) using the information processing theory. Moreover, the study also examines the mediating role of information processing capability and the moderating role of digital technology (DT) deployment.
Design/methodology/approach
A total of 288 questionnaires were collected from the Chinese manufacturing industry, and hierarchical regression was used to empirically test the proposed model.
Findings
This study reveals that SCG positively impacts SCR. Moreover, information processing capability plays a mediating role between SCG and SCR. Furthermore, the breadth of DT deployment positively moderates the effect of relational governance on information processing capability, and the depth of DT deployment positively moderates the effects of both relational governance and contractual governance on information processing capability.
Originality/value
This study offers a novel perspective that helps to understand the importance of the supply chain-wide information acquired by SCG in respect of improving SCR. Furthermore, this article extends the application of information processing theory by providing empirical evidence of the mediating role of information processing capability and elucidating the moderating role of DT deployment.

Abstract
Purpose
Supply chain resilience (SCR) has attracted much attention in the context of the high uncertainty caused by the coronavirus disease 2019 (COVID-19), local regional conflicts and natural disasters. Based on information processing theory (IPT), this study investigates the role of supply chain information processing capability in enhancing SCR through supply chain governance (SCG), under different conditions of environmental uncertainty.
Design/methodology/approach
The hypothetical model is tested by using hierarchical regression on the primary samples collected from the Chinese manufacturing industry.
Findings
The results indicate that supply chain information processing capability has a significant positive effect on SCR. Also, SCG plays a mediating role between supply chain information processing capability and SCR. Furthermore, environmental uncertainty positively moderates the effect of supply chain information acquisition and supply chain information analysis on relational governance. However, environmental uncertainty only positively moderates the effect of supply chain information analysis on contractual governance.
Originality/value
This is the first study to explain the effect of information processing capability on SCR from the supply chain perspective, while also exploring the mediating role of SCG between SCR and supply chain information processing capacity, based on IPT.
