Purpose The purpose of this paper is to empirically examine the mediating role of potential and realized absorptive capacity in intellectual capital (IC) and business performance. It also investigates the direct impact of the components of IC on business performance. Design/methodology/approach Partial least square-structural equation modeling (PLS-SEM) was used to assess the effect of IC dimensions on performance and to analyze the mediating role of absorptive capacity in this relationship. Data were collected from 192 managers using a survey questionnaire with Likert scale items. Findings The findings of the study show that potential absorptive capacity does not intervene in the relationship between the components of IC and those of business performance. However, realized absorptive capacity, measured as the transformation and exploitation of knowledge, played a positive mediating role in the relationship between the dimensions of IC and those of business performance. Social capital was also noted as a weak predictor of business performance, while human capital and organizational capital had a profound positive influence. Originality/value This study contributes to the literature on IC by examining the role of realized and potential absorptive capacity in the relationship between IC components and firm performance. This research also helps practitioners recognize the importance of transformation and the exploitation of knowledge for business performance.

Background Tranexamic acid reduces surgical bleeding and reduces death due to bleeding in patients with trauma. Meta-analyses of small trials show that tranexamic acid might decrease deaths from gastrointestinal bleeding. We aimed to assess the effects of tranexamic acid in patients with gastrointestinal bleeding. Methods We did an international, multicentre, randomised, placebo-controlled trial in 164 hospitals in 15 countries. Patients were enrolled if the responsible clinician was uncertain whether to use tranexamic acid, were aged above the minimum age considered an adult in their country (either aged 16 years and older or aged 18 years and older), and had significant (defined as at risk of bleeding to death) upper or lower gastrointestinal bleeding. Patients were randomly assigned by selection of a numbered treatment pack from a box containing eight packs that were identical apart from the pack number. Patients received either a loading dose of 1 g tranexamic acid, which was added to 100 mL infusion bag of 0•9% sodium chloride and infused by slow intravenous injection over 10 min, followed by a maintenance dose of 3 g tranexamic acid added to 1 L of any isotonic intravenous solution and infused at 125 mg/h for 24 h, or placebo (sodium chloride 0•9%). Patients, caregivers, and those assessing outcomes were masked to allocation. The primary outcome was death due to bleeding within 5 days of randomisation; analysis excluded patients who received neither dose of the allocated treatment and those for whom outcome data on death were unavailable. This trial was registered with Current Controlled Trials, ISRCTN11225767, and ClinicalTrials.gov, NCT01658124.

PurposeThe study aims to examine the mediating role of psychological empowerment and job crafting between servant leadership and innovative work behavior.Design/methodology/approachThe data were collected from 689 knowledge workers employed in Pakistan's service industry. The data collection was done through survey design. The data analysis was done through structural equation modeling using PLS-Smart.FindingsServant leadership was found to be related to psychological empowerment, job crafting and innovative work behavior of the employees. Job crafting was found to be mediating between servant leadership and innovative work behavior. Additionally, psychological empowerment and job crafting were found to be sequential mediators between servant leadership and innovative work behavior.Originality/valueThe study delineated the link mechanism between servant leadership and innovative work behavior.

PurposeThis study aims to ascertain the role of servant leadership in inducing flow at work. The study, along with confirming the relation between flow at work and innovative work behavior (IWB), intends to explore the mediating role flow at work plays in relating servant leadership to IWB.Design/methodology/approachThe data collection was conducted through an interviewee-administered questionnaire in three waves that were four weeks apart. The data were collected from 267 respondents. To run the measurement model and structural model, Smart-PLS was used, and Statistical Product and Service Solutions (SPSS) was used to summarize the demographic information and conduct hierarchal regression.FindingsServant leadership is related to flow at work. Additionally, flow at work is related to IWB. Finally, flow at work mediates the relationship between servant leadership and IWB.Originality/valueThe study found servant leadership is related to flow at work. Moreover, the study unearthed the relation between flow at work and IWB. Finally, the study unveiled that flow at work acts as a mediator between servant leadership and IWB.

PurposeThe purpose of the study is to ascertain the mediating role of meaning between servant leadership and work engagement. The study also explores the relationship between servant leadership and work engagement.Design/methodology/approachThe data were collected from 704 service sector employees working in Pakistan through survey design. The data analysis was done through structural equation modeling using PLS-Smart and hierarchical regression using SPSS.FindingsThe results revealed that servant leadership was related to meaning and work engagement. Moreover, meaning was found to be related to work engagement. Finally, meaning was found to mediate the relationship between servant leadership and work engagement.Originality/valueThe research has ascertained the previously unexplored mediating role of meaning between servant leadership and work engagement.
