Abstract

Purpose

The purpose of this study was to explore the potential benefits of Coriandrum sativum (C. sativum) on anxiety, depression, sleep quality and memory among students.

Design/methodology/approach

This randomized controlled trial involved university students aged 18–25 years, who had no known allergies to C. sativum or were using psychotropic medication. After giving informed consent, participants were randomly assigned using a computer-generated random sequence to either 500 mg C. sativum seeds or a placebo. Primary outcomes measured changes in memory (prospective and retrospective memory questionnaire [PRMQ]), anxiety and depression (Hospital Anxiety and Depression Scale), while secondary outcomes assessed sleep quality (Pittsburgh sleep quality inventory [PSQI]).

Findings

A sample of 86 students with a mean age of 20.05 ± 1.6 years was selected for the study. Initial assessments ensured no significant differences in demographic or study variables between the control and intervention groups. Statistical analysis revealed significant improvements in memory (PRMQ: p = 0.006), anxiety (Hospital Anxiety Scale: p = 0.04) and depression (Hospital Depression Scale: p = 0.002), as well as in sleep quality (PSQI: p = 0.03) in the group receiving C. sativum compared to the control group.

Originality/value

This research offers initial insights into the potential benefits of C. sativum intake, specifically its role in enhancing memory performance and mitigating anxiety among student populations. The results present a compelling case for further research in this domain to solidify these preliminary conclusions.

Abstract

Purpose

Although research analyzing the consequences of salesperson social media use in driving sales behaviors and performance outcomes has proliferated in the recent past, there are significant research gaps in the domain. Grounded in task-technology fit theory, this paper aims to propose a conceptual framework that integrates between previously disjointed areas of research and analyzes the relationships between salesperson social media use, brand awareness, creativity, manager empowerment and company performance.

Design/methodology/approach

Survey responses were collected from a multi-industry sample of 158 business-to-business salespeople. Structural relationships were tested using partial least squares structural equation modeling.

Findings

The analysis shows that salesperson social media use positively affects brand awareness. The relationship between social media and brand awareness is magnified with the increase in salesperson creativity. Findings also show that manager empowerment increases salesperson creativity. Finally, brand awareness positively affects company performance.

Practical implications

Sales organizations should focus on developing digital strategies, especially focusing on salesperson social media use to enhance company’s brand awareness, which in turn increases company performance. Moreover, sales managers should also follow empowering leader behaviors to enhance creativity.

Originality/value

The authors amalgamate salesperson social media use literature and branding literature by proposing salesperson social media use’s positive effects on brand awareness. This study also expands the knowledge by exploring the moderating effect of individual-level variables such as salesperson creativity on driving the effects of salesperson social media use.

Abstract

Purpose

This study examines the contextual variables that can curb the negative effects of role conflict on job satisfaction and enhance the positive effect of job satisfaction on creativity and service performance. More specifically, adopting the job demands-resources theory, the authors explore the interactive effect of frontline employee (FLE) self-monitoring and FLE-manager trust on the relationship between role conflict and job satisfaction. Extending this line of inquiry, the authors adopt social identity theory and analyze the moderating effect of FLE-manager identification on the relationship between job satisfaction and creativity and between job satisfaction and service performance.

Design/methodology/approach

Dyadic data utilizing 122 responses from FLEs and their managers were obtained from FLEs working with a major financial services firm in India. Structural equation modeling and PLS were used to assess the hypothesized relationships.

Findings

The negative relationship between role conflict and job satisfaction is reduced at higher levels of FLE self-monitoring and FLE-manager trust. Furthermore, FLE manager identification accentuates the effect of job satisfaction on creativity and service performance.

Practical implications

Organizations should invest in developing FLEs' personal and job-related resources to reduce the deleterious effects of role conflicts on FLEs' job outcomes. Specifically, managers should hire FLEs who are high in self-monitoring while enhancing FLE-manager trust and FLE-manager identification.

Originality/value

Role conflict is inevitable in a service job and can have serious negative downstream consequences. Hence, the study explores the important contextual factors that can help an organization develop policies to reduce the negative effects of role conflict.
