Functional selectivity for social interaction perception in the human superior temporal sulcus during natural viewing
Authors: Lee Masson Haemy , Isik Leyla 
Published: March 2021

AbstractRecognizing others’ social interactions is a crucial human ability. Using simple stimuli, previous studies have shown that social interactions are selectively processed in the superior temporal sulcus (STS), but prior work with movies has suggested that social interactions are processed in the medial prefrontal cortex (mPFC), part of the theory of mind network. It remains unknown to what extent social interaction selectivity is observed in real world stimuli when controlling for other covarying perceptual and social information, such as faces, voices, and theory of mind. The current study utilizes a functional magnetic resonance imaging (fMRI) movie paradigm and advanced machine learning methods to uncover the brain mechanisms uniquely underlying naturalistic social interaction perception. We analyzed two publicly available fMRI datasets, collected while both male and female human participants (n = 17 and 18) watched two different commercial movies in the MRI scanner. By performing voxel-wise encoding and variance partitioning analyses, we found that broad social-affective features predict neural responses in social brain regions, including the STS and mPFC. However, only the STS showed robust and unique selectivity specifically to social interactions, independent from other covarying features. This selectivity was observed across two separate fMRI datasets. These findings suggest that naturalistic social interaction perception recruits dedicated neural circuity in the STS, separate from the theory of mind network, and is a critical dimension of human social understanding.Significance StatementSocial interaction perception guides our daily behavior, yet it is unknown how our brain processes real-world social interaction scenes. Here, we demonstrate that social brain areas, including the superior temporal sulcus (STS) and medial prefrontal cortex (mPFC), are sensitive to broad social-affective information in naturalistic movies, replicating prior results with controlled paradigms. We show for the first time however, that the STS, but not mPFC, selectively processes social interactions in natural movies, independent of other co-occurring perceptual and social features, including motion, presence of faces, speech, and mentalizing about others. Our results suggest that social interaction perception is a crucial dimension of social understanding represented in the human brain.

ABSTRACTVaccines that induce potent neutralizing antibody (NAb) responses against emerging variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are essential for combating the coronavirus disease 2019 (COVID-19) pandemic. We demonstrated that mouse plasma induced by self-assembling protein nanoparticles (SApNPs) that present 20 rationally designed S2GΔHR2 spikes of the ancestral Wuhan-Hu-1 strain can neutralize the B.1.1.7, B.1.351, P.1, and B.1.617 variants with the same potency. The adjuvant effect on vaccine-induced immunity was investigated by testing 16 formulations for the multilayered I3-01v9 SApNP. Using single-cell sorting, monoclonal antibodies (mAbs) with diverse neutralization breadth and potency were isolated from mice immunized with the receptor binding domain (RBD), S2GΔHR2 spike, and SApNP vaccines. The mechanism of vaccine-induced immunity was examined in mice. Compared with the soluble spike, the I3-01v9 SApNP showed 6-fold longer retention, 4-fold greater presentation on follicular dendritic cell dendrites, and 5-fold stronger germinal center reactions in lymph node follicles.ONE-SENTENCE SUMMARYWith a well-defined mechanism, spike nanoparticle vaccines can effectively counter SARS-CoV-2 variants.
Governance mechanism alignment at the top and operating levels of alliance hierarchy: reconciling two competing schools of thought
Authors: Bai Xuan , Sheng Shibin , Li Julie Juan 
Published: March 2021

PurposeThis paper aims to examine alliance governance at different hierarchical levels.Design/methodology/approachThe data is collected from both top-level and operating-level managers in 286 strategic alliances in China (a total of 572 managers). Hierarchical moderated regression models are adopted to test the hypotheses and two-stage regression analyzes are used to correct for endogeneity.FindingsThis paper finds that relational governance has a greater impact on alliance performance than contract utilization at the top level. Furthermore, the simultaneous use of relational governance at the top and operating levels have a detrimental impact on alliance performance. Finally, top-level contract utilization has a negative interaction with operating-level relational governance but a positive interaction with operating-level contract utilization.Research limitations/implicationFirst, the cross-sectional nature of the data collection approach provides only a snapshot of how each type of governance mechanism and its interactions affect alliance performance. Second, the sample is limited to firms located in emerging markets.Practical implicationsManagers should realize that the effectiveness of contract and relational governance mechanisms varies across different management levels and they should be cautious about the cross-level governance mechanism alignment.Originality/valueThis study advances the interfirm governance literature in that this paper examined alliance governance at different hierarchical levels and provides new insights into the ongoing debate on whether the contract and relational governance mechanisms function as complements or substitutes by exploring the governance alignment across different alliance hierarchies.
Gender differences in predictors of technology threat avoidance
Authors: Gillam Andrew R. , Waite Alina M. 
Published: March 2021

PurposeThe purpose of this paper is to examine gender differences in predictors of technology threat avoidance motivation and behavior among working US adults. Implications were considered in regard to cybersecurity awareness training motivation and perceptions of need for protective cybersecurity behavior in the workplace.Design/methodology/approachA single-shot regression-based study used ordinal regression supported by K-means clustering to evaluate the moderating effects of gender on predictors of technology threat avoidance motivation and behavior on a sample ofn = 206 US adult workers.FindingsThe regression model explained 47.5% of variance in avoidance motivation and 39% of avoidance behavior variance. Gender moderated predictive associations between several independent variables and avoidance motivation: perceived susceptibility, perceived effectiveness, perceived cost and self-efficacy. Gender also moderated the association between avoidance motivation and avoidance behavior.Research limitations/implicationsThe predictive impact of gender extends beyond the main effects in technology threat avoidance. Data frequency distributions and inter-variable relationships should be routinely considered in threat avoidance studies, especially if sample variables exhibit non-normal frequency distributions and nonlinear associations.Practical implicationsGender was significantly associated with threat avoidance motivation and avoidance behavior and exhibited notable associations with antecedents of avoidance motivation. Related insights can inform the design and delivery of training content relating to technology threat avoidance as organizations strive to more effectively leverage information technology end-users as protective assets for the enterprise.Originality/valueThe uniqueness of this study derives from its focus and findings regarding the moderating effects of gender on technology threat avoidance factors and techniques used to measure and evaluate the associations between them.
Users’ attitude on perceived security of enterprise systems mobility: an empirical study
Authors: Palanisamy Ramaraj , Wu Yang 
Published: March 2021

Purpose
This study/ paper aims to empirically examine the user attitude on perceived security of enterprise systems (ES) mobility. Organizations are adopting mobile technologies for various business applications including ES to increase the flexibility and to gain sustainable competitive advantage. At the same time, end-users are exposed to security issues when using mobile technologies. The ES have seen breaches and malicious intrusions thereby more sophisticated recreational and commercial cybercrimes have been witnessed. ES have seen data breaches and malicious intrusions leading to more sophisticated cybercrimes. Considering the significance of security in ES mobility, the research questions in this study are: What are the security issues of ES mobility? What are the influences of users’ attitude towards those security issues? What is the impact of users’ attitude towards security issues on perceived security of ES mobility?

Design/methodology/approach
These questions are addressed by empirically testing a security model of mobile ES by collecting data from users of ES mobile systems. Hypotheses were evolved and tested by data collected through a survey questionnaire. The questionnaire survey was administered to 331 users from Chinese small and medium-sized enterprises (SME). The data was statistically analysed by tools such as correlation, factor analysis, regression and the study built a structural equation model (SEM) to examine the interactions between the variables.

Findings
The study results have identified the following security issues: users’ attitude towards mobile device security issues; users’ attitude towards wireless network security issues; users’ attitude towards cloud computing security issues; users’ attitude towards application-level security issues; users’ attitude towards data (access) level security issues; and users’ attitude towards enterprise-level security issues.

Research limitations/implications
The study results are based on a sample of users from Chinese SMEs. The findings may lack generalizability. Therefore, researchers are encouraged to examine the model in a different context. The issues requiring further investigation are the role of gender and type of device on perceived security of ES mobile systems.

Practical implications
The results show that the key security issues are related to a mobile device, wireless network, cloud computing, applications, data and enterprise. By understanding these issues and the best practices, organizations can maintain a high level of security of their mobile ES.

Social implications
Apart from understanding the best practices and the key issues, the authors suggest management and end-users to work collaboratively to achieve a high level of security of the mobile ES.

Originality/value
This is an empirical study conducted from the users’ perspective for validating the set of research hypotheses related to key security issues on the perceived security of mobile ES.
Integrating professional sustainability literacy into the master of public administration curriculum
Authors: Kinzer Kirsten 
Published: March 2021

Purpose
Public administration, or the implementation of public policies by civil servants, will be central to implementing the Agenda 2030 Sustainable Development Goals. And yet, few American master of public administration (MPA) programs explicitly focus on sustainable development or sustainability literacy. This study asks whether it is possible to build professional sustainability literacy within a general MPA course, specifically in a course on quantitative methods.

Design/methodology/approach
Through a natural experiment conducted in three sections of the graduate course Quantitative Methods in Public Administration at UNC Wilmington, the study explores the relationship between student growth in professional sustainability literacy and a student’s level of foundational sustainability literacy, pro-environmental behavior, background knowledge in statistics and their interest in sustainable development within public administration.

Findings
The study finds that there is a statistically significant relationship between growth in a student’s professional sustainability literacy and two variables: above average foundational sustainability literacy and a high level of interest in sustainability policies and programs.

Originality/value
This study is the first to consider an embedded approach to sustainability education in the field of public administration.

Authors: Xie Xianyi , Jin Lisheng , Baicang Guo , Shi Jian 
Published: March 2021

Purpose
This study aims to propose an improved linear quadratic regulator (LQR) based on the adjusting weight coefficient, which is used to improve the performance of the vehicle direct yaw moment control (DYC) system.

Design/methodology/approach
After analyzing the responses of the side-slip angle and the yaw rate of the vehicle when driving under different road adhesion coefficients, the genetic algorithm and fuzzy logic theory were applied to design the parameter regulator for an improved LQR. This parameter regulator works according to the changes in the road adhesion coefficient between the tires and the road. Hardware-in-the-loop (HiL) tests with double-lane changes under low and high road surface adhesion coefficients were carried out.

Findings
The HiL test results demonstrate the proposed controllers’ effectiveness and reasonableness and satisfy the real-time requirement. The effectiveness of the proposed controller was also proven using the vehicle-handling stability objective evaluation method.

Originality/value
The objective evaluation results reveal better performance using the improved LQR DYC controller than a front wheel steering vehicle, especially in reducing driver fatigue, improving vehicle-handling stability and enhancing driving safety.

Authors: Kasri Rahmatina Awaliah , Chaerunnisa Syafira Rizma 
Published: March 2021

PurposeThis study aims to determine the role of knowledge, trust and religiosity in influencing the intention to donate cash waqf online among Muslim millennials in Indonesia.Design/methodology/approachUsing a framework based on the theory of planned behavior, primary data was collected from 418 Muslim millennials who domiciled in large cities in Indonesia and subsequently analyzed using the structural equation modeling method.FindingsThe main findings suggest that knowledge, trust and religiosity play a positive role in explaining the intention to donate cash waqf online among Indonesia’s millennials. Religiosity is found to be the most powerful factor in influencing attitude, while knowledge is the least significant factor influencing the attitude, which subsequently influences the intention to engage in online cash waqf. Social norms and perceived behavioral control are also positively influencing such intention.Practical implicationsThese results imply that it is important for waqf institutions to reflect strong Islamic values in their cash waqf products and to more strongly communicate religious messages about the benefits of giving cash waqf to the millennials. It is also crucial to increase waqf literacy through appropriate campaigns. Moreover, they need to be more transparent and accountable to establish, maintain and enhance trust in their organizations. Overall, these findings are expected to provide insights enabling waqf institutions to devise effective marketing strategies for raising the level of online cash waqf donation in Indonesia.Originality/valueThis is thought to be one of the first studies to investigate the factors influencing online cash waqf donations among Muslim millennials in Indonesia.
The halal tourism – alternative or mass tourism? Indications of traditional mass tourism on crescent rating guidelines on halal tourism
Authors: Rhama Bhayu 
Published: March 2021

Purpose
This study aims to identify whether halal tourism, as advocated by Mastercard-Crescent Rating guidelines on halal tourism can be considered as supporting sustainable tourism.

Design/methodology/approach
Three Mastercard-CrescentRating 2019 Reports which are Global Muslim Travel Index, Indonesia Muslim Travel Index and Halal Travel Frontier were evaluated using a qualitative method supports by NVivo software to analyze text and images. Eight indicators (number of tourists, main motivations, main values, interaction with the community, interaction with the environment, most possible destinations, infrastructure and visitor monitorings) are used to classify halal tourism items into mass tourism (traditional, experiential and sensational) and non-mass (alternative) tourism. The qualitative analysis is supported by correlation analysis of GMTI scores with environmental performance index and the global sustainable competitiveness index scores.

Findings
The results showed that halal tourism has unique characters compared with mass and non-mass tourism types. However, halal tourism advocated by CrescentRating unlikely shows similarity with non-mass tourism. It tends to be traditional mass tourism, especially on the perspective of the type of activity, interactions with the environment and local communities, as well as the main values.

Originality/value
Previous research suggested the needs of halal tourism and its relations to sustainability. This research fills the gap by showing the halal tourism, in the perspective of Mastercard-CrescentRating is not prioritized toward sustainable tourism by qualitative and quantitative evidences. This study contributes to the knowledge of sustainability from Islamic perspectives and practices and provides a way to the theory of Islamic sustainable tourism. It also suggests improvements to halal tourism guidelines such as the transparency and guarantees that the profit will be used for social welfare, promotion of sustainability using Qur’anic verses and promotion on environmental and social empowerment activities.
A dynamic performance management approach to frame corruption in public procurement: a case study
Authors: Gnoffo Salvatore 
Published: March 2021

Purpose
The purpose of this paper is to frame the causal relationships between corruption in public procurement and performance of local governments.

Design/methodology/approach
An outcome-based dynamic performance management approach is adopted to explore a representative case study of a small Italian municipality. The model is based on three sources: qualitative primary data generated by face-to-face convergent interviews; secondary data retrieved from documents describing legal cases linked to procurement and open-access repositories; and an extensive literature review.

Findings
Emphasizing the role of community civic morality systemically may help to understand some counterintuitive results in the past research and support decision-makers and policymakers in setting effective strategies to curb the associated negative implications.

Social implications
A dynamic approach of performance management aimed at framing corruption in public procurement may guide policymakers and decision-makers in keeping their “cognitive radar” constantly active, in a way to detect emerging corruptive phenomena that could be otherwise ignored by normal diagnostical approaches. It may also help to promote organizational ethical learning and improve community outcomes.

Originality/value
This research provides a causal and systemic framework of relationships involving local government performance and wrongdoings in public procurement, by including performance risk indicators linked to structural and individualistic causes of corruption.

Authors: Soni Manjari , Jain Kokil , Jajodia Isha 
Published: March 2021

Purpose
The emergence of mHealth applications has led to the rise of health-based services delivered over smartphones. Younger people are often found to be more innovative toward technology, especially related to smartphones (Rai et al., 2013). Most mHealth application downloaders are continually shifting between applications because of the hyper-competition making achieving loyal consumers challenging (Racherla et al., 2012). The purpose of this paper is to study the determinants that help increase young consumers mHealth application loyalty. This study integrates self-determination theory (SDT), gamification elements and engagement to examine loyalty.

Design/methodology/approach
A valid sample of 263 college student’s data was obtained for data analysis from a survey conducted in multiple campuses of the Delhi University in India.

Findings
The three psychological needs: need for autonomy, need for competence and need for relatedness, showed a positive impact on intrinsic motivation. From the gamification factors; perceived playfulness, the level of challenge and social interaction, only the first two showed a positive impact on extrinsic motivation. Both motivation factors influence engagement, showing a frequent interaction with the application, leading to loyalty.

Originality/value
Previous studies examined the adoption of mHealth services, this study is one of the first to examine young consumers’ loyalty in using mhealth apps. It sheds light on the existing literature and contributes to research on mHealth applications by determining the factors that lead to loyalty by the young consumers.
Galactocerebroside biosynthesis pathways of Mycoplasma species: an antigen triggering Guillain–Barré–Stohl syndrome
Authors: Gaspari Erika , Koehorst Jasper J. , Frey Joachim , Martins dos Santos Vitor A.P. , Suarez‐Diez Maria 
Published: March 2021

SummaryInfection by Mycoplasma pneumoniae has been identified as a preceding factor of Guillain–Barré–Stohl syndrome. The Guillain–Barré–Stohl syndrome is triggered by an immune reaction against the major glycolipids and it has been postulated that M. pneumoniae infection triggers this syndrome due to bacterial production of galactocerebroside. Here, we present an extensive comparison of 224 genome sequences from 104 Mycoplasma species to characterize the genetic determinants of galactocerebroside biosynthesis. Hidden Markov models were used to analyse glycosil transferases, leading to identification of a functional protein domain, termed M2000535 that appears in about a third of the studied genomes. This domain appears to be associated with a potential UDP‐glucose epimerase, which converts UDP‐glucose into UDP‐galactose, a main substrate for the biosynthesis of galactocerebroside. These findings clarify the pathogenic mechanisms underlining the triggering of Guillain–Barré–Stohl syndrome by M. pneumoniae infections.
