Abstract
Purpose
The purpose of this paper is to investigate the effect of materials, three dimensional (3D) structure and number of fabric layers on ultraviolet protection factor (UPF), air permeability and thickness of fabrics.
Design/methodology/approach
Total 24 fabrics samples were developed using two 3D structures and two weft materials. In warp direction cotton (CT) yarn and in weft direction polypropylene (PP) and polyester (PET) were used. Air permeability, thickness and UPF testings were performed and relationship among fabric layers, air permeability, thickness and UPF was developed.
Findings
UPF and thickness of fabrics increases with number of fabric layers, whereas air permeability decreases with the increase in number of fabric layers. Furthermore, change of multilayer structure from angle interlock to orthogonal interlock having same base weave does not give significant effect on UPF. However, change of material from polyester (PET) to polypropylene (PP) has a dominant effect on UPF. Minimum of three layers of cotton/polyester fabric, without any aid of ultraviolet radiation (UV) resistant coating, are required to achieve good. Cotton/polyester fabrics are more appropriate for outdoor application due to their long-term resistance with sunlight exposure.
Originality/value
Long-term exposure to UV is detrimental. So, there is need of proper selection of material and fabric to achieve ultraviolet protection. 3D fabrics have yarns in X, Y as well as in Z directions which provide better ultraviolet protection as compared to two dimensional (2D) fabrics. In literature, mostly work was done on ultraviolet protection of 2D fabrics and surface coating of fabrics. There is limited work found on UPF of 3D woven fabrics.

This paper aims to develop bilayer woven fabrics with different picking sequences with enhanced comfort without any change in the constituent materials.
Abstract
Purpose
This paper aims to develop bilayer woven fabrics with different picking sequences with enhanced comfort without any change in the constituent materials.
Design/methodology/approach
Six bilayer woven fabrics were produced on Dobby loom with 3/1 twill weave using micro-polyester yarn. Three different picking sequences, i.e. single pick insertion (SPI), double pick insertion (DPI) and three pick insertion (3PI), were used in both face and back layers. The effect of picking sequence on air permeability (AP), volume porosity, thermal resistance and overall moisture management capability (OMMC) of the samples were analyzed.
Findings
The results showed that 3PI–3PI picking sequence gives the highest OMMC, AP and thermal resistance in bilayer woven fabrics and the least results exhibited by SPI–SPI picking sequence.
Research limitations/implications
This research uses a bilayer woven system that develops channels and trapes the air causing higher thermal resistance; therefore, applicable for winter sports clothing rather than for summer wear. Developed bilayer woven fabrics can be used in winter sportswear to improve the comfort of the wearer and reduce fatigue during activity.
Originality/value
Authors have developed bilayer fabrics by changing the picking sequences, i.e. SPI, DPI and 3PI of weft yarns in both layers and compared their thermo-physiological comfort properties.

This paper aims to investigate the influence of picking sequence, weave design and weft yarn material on the thermal conductivity of the woven fabrics.
Abstract
Purpose
This paper aims to investigate the influence of picking sequence, weave design and weft yarn material on the thermal conductivity of the woven fabrics.
Design/methodology/approach
This work includes the development of 36 woven samples with two weave designs (1/1 plain and 3/1 twill), three picking sequences (single, double and three pick insertion) and six different weft yarn materials (cotton, polyester having 48 filaments, polyester with 144 filaments, spun coolmax having Lycra in core and coolmax in sheath, filament coolmax and polypropylene). The thermal conductivity was measured using ALAMBETA tester.
Findings
The results showed that weft yarn material, weave design and picking sequence have a meaningful impact on the thermal conductivity of woven fabric. The value of thermal conductivity was lowest for the fabrics with three pick insertion and 3/1 twill weave in all weft yarn materials.
Research limitations/implications
Plain woven fabric with single pick insertion is feasible for summer wear to enhance the comfort of wearer. By changing the warp yarn grouping and material, improved thermal conductivity/resistance can also be achieved.
Originality/value
The authors have studied the combined effect of different weft yarn materials with different picking sequences and different weave designs on thermal conductivity of the woven fabrics.

Abstract
Purpose
Literature on workplace learning emphasizes that learning should be continually generated and negotiated in the workplace. How does this concept unfold in the developing context? This paper aims at understanding teachers' workplace learning and the conditions which influence such learning in a private school of Pakistani context.
Design/methodology/approach
First, a brief review of literature on workplace learning is presented to develop a conceptual framework for the study. Next, the research methodology undertaken to collect data from the studied school is described. The paper then presents the findings, followed by discussion, limitations and suggestions for further studies.
Findings
Drawing upon the data collected through a qualitative case study, this paper reveals that in Pakistani schools, the theoretically powerful concept of learning is not the same in practice. Teachers' work load, lack of awareness about the possibilities and importance of workplace learning, non‐existence of structures for teachers' interactions and lack of rewards are the conditions impeding workplace learning. Since the study has been conducted in the developing context, it also brings forth some fresh findings about cultural aspects of the specific context.
Originality/value
The study suggests that the change agents should concentrate on developing structures and cultures inside schools to facilitate teachers' workplace learning. Moreover, the external courses conducted for teachers should include the concept of workplace learning in their contents to make teachers learn how to learn in the workplace.

Abstract
Purpose
This paper argues that teachers’ promotion should also have an impact on turnover intention. The purpose of this paper is to determine the relationship between promotion and turnover intention of advance learning institutions of the Khyber Pakhtoon Khwa Province of Pakistan and the moderating effect of the analytical cognitive style.
Design/methodology/approach
A quantitative approach is used predominantly. A questionnaire survey research design is used to collect the data from the entire province and 502 completed questionnaires were collected from the respondents. The questionnaire included the Job Descriptive Index consisting of seven items on job satisfaction, the turnover intention questionnaire consisting of three items and a five-point Likert scale used to determine cognitive style index (CSI); the CSI was used. The fourth section included an open-ended questionnaire and the fifth section included demographic variables. Hierarchical multiple regressions were used to check how much variance promotion occurs upon turnover intention and it also determined how much variance analysis cognitive style occurs upon promotion and turnover intention of advance learning institutions of the KPK province of Pakistan. The correlation results from a bivariate Pearson correlation showed significant results, which were later strengthened by the regression results.
Findings
The findings suggested that a negative relationship was found between promotion and turnover intention, whereas a weak correlation was found between promotion and analytical. Moderating results show that analytical cognitive style does act as a moderator between the promotion and turnover intention.
Research limitations/implications
This research was only carried out on advance learning institutions; thus, the findings can only be generalized to higher education institutions in the Khyber Pakhtoon Khwa state.
Practical implications
This extended model of job satisfaction will be useful to lead to changes in job satisfaction and turnover intention of academicians of the Khyber Pakhtoon Khwa province of Pakistan. The findings of this study could be used to guide the management of advance learning institutions and professional academicians to build targeted learning activities around key components of the academician’s promotion, determine where individuals are in their journey, set personalized goals and provide feedback to the management in the process of the development of policies for academicians of advance learning institutions.
Social implications
The findings of this study will help the higher education commission of Pakistan to make policies that will enable higher education institutions to formulate flexible promotion policies for teachers in order to retain them.
Originality/value
The findings of this study are a valuable extension of the relevant research as this is the first empirical study to examine the effects of cognitive style on promotion policies and turnover intention in advance learning institutions of Pakistan. In the context of an efficient and effective educational policy, a greater understanding of an academician’s promotion could facilitate the development of a more effective policy practice that would increase not only the job satisfaction of the academicians but decrease the turnover intention of the academicians.

Abstract
Purpose
This paper aims to investigate the influence of corporate social responsibility (CSR) on employee engagement (EE) through mediating effect of personal environmental norms (PEN) and employee green behavior (EGB).
Design/methodology/approach
The proposed model was validated using 360 employees data from manufacturing and service industries.
Findings
The findings confirmed that CSR is the positive and significant driver of EE. The results also demonstrated PEN and green employee behavior partly mediate this relationship.
Practical implications
The finding of this study enriches the existing literature and social outcomes of CSR. Theoretical and practical contributions have been discussed in detail.
Originality/value
The study demonstrates CSR is significantly related to EE, mediated via PEN and EGB, highlighting the necessity for micro-level CSR research. To the best of the authors’ knowledge, this is the first and foremost empirical research that establishes the mediating effects of PEN and EGB between CSR and EE in the Indian context.

Abstract
Purpose
Taking an evidence from social exchange theory, this research examines the mediating role of affective commitment in the correlation between internal branding, employee engagement and job satisfaction. The moderating role of work environment on the link between internal branding and affective commitment is also studied in this research.
Design/methodology/approach
The data were collected by using well-structured research measures from 215 employees working in the BPO sector of India (Punjab and Chandigarh). The hypotheses were developed, and the conceptual model was validated by applying structural equation modeling. The data were analyzed by using two statistical packages, namely SPSS and AMOS.
Findings
The findings suggest that internal branding has a significant positive relationship with employee engagement, job satisfaction and affective commitment. The mediating effect of affective commitment on the relationship between internal branding and employee engagement was full, whereas on the relationship between internal branding and job satisfaction, it was partial. Work environment also moderated the relationship of internal branding with affective commitment.
Research limitations/implications
The current study offers significant lessons to management thinkers, human resource (HR), organizational branding and marketing manager. However, BPO sector should be aware about the critical role played by internal branding to enhance affective commitment, employee engagement and job satisfaction of the employees. The role of affective commitment is also taken into account to study the effect of internal branding on employee engagement and employee's job satisfaction. For itself, internal branding cannot be considered as in isolation and is doubtful to be efficacious if the work environment is not encouraging to an employee as well as to the brand values.
Practical implications
This study offers significant lessons to management thinkers, HR, organizational branding and marketing manager. However, BPO sector should be aware about the critical role played by internal branding to enhance employee engagement, job satisfaction and affective commitment of the employees. An important role of affective commitment is also taken into account to study the effect of internal branding on employee engagement and employee's job satisfaction. For itself, internal branding cannot be considered as in isolation and is doubtful to be efficacious if employees are not provided an encouraging work environment.
Originality/value
Existing researches on internal branding are theoretical in nature and overlook the empirical impact of internal branding on employee engagement, job satisfaction and affective commitment from the BPO employees' perspective. The study also offers an empirical examination of potential mediator and moderator for internal branding.
