Abstract

Purpose

Unlike multinational companies, small and mid-size enterprises (SMEs) have budget constraints and, thereby, cannot invest heavily in improving the creativity of employees. They look for alternative budget-friendly ways to do the same. The authors of the current paper attempt to identify two psychological-based constructs which positively influence creativity among employees. Both these psychological constructs may be improved among the employees using suitable interventions from the human resource (HR) professionals and line managers working in the organization. This study is an attempt to test the influence of organization-based self-esteem (OBSE) and psychological capital (PC) (both malleable) on creative performance behaviour (CPB) among SME employees.

Design/methodology/approach

Validated instruments were used to collect data. Structural equation model (SEM) was used to evaluate the 377 responses collected from the employees working in three SME's in India. All three SMEs work in the area of innovative process design and require a high level of creativity among employees.

Findings

PC fully mediates the relationship between OBSE and the CPBs of employees. Employees experiencing higher levels of OBSE will develop higher self-esteem, and these employees will exhibit more creative behaviours, increasing the likelihood of achieving creative results.

Research limitations/implications

This study provides valuable inputs to the creativity literature as it describes the process of how self-esteem influences the creativity of an employee. HR professionals working in SMEs can work on enhancing the OBSE and PC (both malleable) of employees to improve creativity among employees.

Originality/value

To the best of the researcher's knowledge, this is the first attempt to identify frugal ways to improve creativity, especially in SMEs.

Abstract

Purpose

This study aims to describe the design and synthesis of two novel azo and imine chromophores-based dyes derived from two different aldehydes with intramolecular colour matching that are pH sensitive.

Design/methodology/approach

The visible absorption wavelength (λmax) was extended when azo chromophore was included in imine-based systems. The dyed patterns created sophisticated colour-changing paper packaging sensors with pH-sensitive chromophores using alum as a mediator or mordant. Due to the tight adhesive bonding, the dyes on paper’s cellulose fibres could not be removed by ordinary water even at extremely high or low pH, which was confirmed by scanning electron microscopy analysis. The dyed patterns demonstrated an evident, sensitive and fast colour-changing mechanism with varying pH, from pale yellow to red for Dye-I and from pale yellow to brown-violet for Dye-II.

Findings

The λmax for colour changing was recorded from 400 to 490 nm for Dye-I, whereas from 400 to 520 for Dye-II. The freshness judgement of food was checked using actual experiments with cooked crab spoilage, where the cooked crab was incubated at 37 oC for 6 h to see the noticeable colour change from yellow to brown-violet with Dye-II. The colour-changing mechanism was studied with Fourier transform infrared (FTIR) spectra at different pH, and thin layer chromatography, nuclear magnetic resonance and FTIR spectroscopy studied the desired structure formation of the dyes. Potential uses for smart packaging sensors include quickly detecting food freshness during transportation or right before consumption.

Originality/value

1. Two novel azo-imine dyes have been synthesized with a pH-responsive effect. 2. The pH-responsive mechanism was studied. 3. The study was supported by computational chemistry using density functional theory. 4. The obtained dyes were used to make pH-responsive sensors for seafood packaging to judge the freshness.
