Abstract

Purpose

This study aims to examine the current state of literature on structural equation modeling (SEM) studies in “cloud computing” domain with respect to study domains of research studies, theories and frameworks they use and SEM models they design.

Design/methodology/approach

Systematic literature review (SLR) protocol is followed. In total, 96 cloud computing studies from 2009 to June 2018 that used SEM obtained from four databases are selected, and relevant data are extracted to answer the research questions.

Findings

A trend of increasing SEM usage over years in cloud studies is observed, where technology adoption studies are found to be more common than the use studies. Articles appear under four main domains, namely, business, personal use, education and health care. Technology acceptance model (TAM) is found to be the most commonly used theory. Adoption, intention to use and actual usage are the most common selections for dependent variables in SEM models, whereas security and privacy concerns, costs, ease of use, risks and usefulness are the most common selections for causal factors.

Originality/value

Previous cloud computing SLR studies did not focus on statistical analysis method used in primary studies. This review will display the current state of SEM studies in cloud domain for all future academics and practical professionals.

Abstract

Purpose

The purpose of this paper is to create a textile material which shows antibacterial activity with resistance to environmental conditions by using volatile active agent inclusion complex and self-assembly method.

Design/methodology/approach

An inclusion complex of carvacrol and β-CD is generated by kneading method and deposited on the cotton fabrics by using a nanofabrication method named as layer-by-layer (LbL) deposition method. Three different concentration of CD and CD:Car aqueous solutions were deposited on cotton fabrics. Attenuated total reflectance Fourier transform infrared spectroscopy (FTIR-ATR), scanning electron microscopy (SEM), antimicrobial efficacy test of fabrics against washing and some physical tests (water vapor permeability, air permeability) were performed on the fabrics before and after the treatment with CD to evaluate the effect of the LbL process on cotton fabric properties.

Findings

The results showed that the coated fabrics with CD/CD:Car multilayer films enhanced the antimicrobial efficacy of cotton fabrics against to Klebsiella pneumonia and Staphylococus aureus bacteria. Air and water vapor permeability properties of the cotton fabric effected after the LbL deposition process sure enough. With SEM and FTIR-ATR analysis the CD:Car complex presence were verified. The durability of antibacterial properties were analyzed after one and ten washing (40°C and 30 min) cycles.

Originality/value

This work provides a novel and simple method for CD and inclusion complex of carvacrol film deposition by self-assembly method on cotton fabrics and their application onto cotton fabrics to gain antibacterial property.
