Purpose In the backdrop of job demands-resources model, the purpose of this paper is to investigate the effect of selected job resources (job autonomy and rewards and recognition) and job demands (problem with work) on innovative work behaviour through the mediation of employee engagement in the higher education sector of India. Design/methodology/approach The sample consists of randomly selected 275 teachers from higher education institutions from a city in India. This study used PLS-SEM for data analysis. Findings The results suggest that employee engagement associates closely with innovative work behaviour. Job autonomy, one of the resources, affects innovative work behaviour directly and its effect does not move via employee engagement. Further, reward and recognition does not impact innovative work behaviour directly, rather, its effect moves through employee engagement. Finally, the work suggests that employee engagement mediates between selected job resources and job demands and innovative work behaviour. Research limitations/implications This study can be extended to include more demands and resources which are unique to academic institutions. For example, a transparent career path to all teachers or a high-octane research culture can serve as a boon. Additionally, their interaction effect can also be studied. The present study being a cross-sectional study, at best, offers a snap-shot view of relationship among the variables. Practical implications This study shall help organizations to use job resources and job demands to enhance teachers’ engagement and innovative work behaviour. Specifically, results of this study offer a reason to academic institutions to give more autonomy and rewards to their teachers to eke out innovative work behaviour. Social implications Firstly, this study will have a positive outcome for students who will be the prime beneficiaries of innovative work behaviour of teachers. Secondly, broadly the society and its constituents will get benefited by improvement in research outcomes. Originality/value The outcome of this study proposes that job autonomy and reward and recognition do not connect with employee engagement and innovative work behaviour in a known way.

In the present work, the photochemical oxidation of phenol and chlorophenol aqueous solutions in a batch recycle photochemical reactor using ultraviolet irradiation, hydrogen peroxide and Ti02 (as photocatalyst) was studied. The study showed that the combined treatment process was the most effective process under acidic conditions and showed a higher rate of degradation of phenol and chlorophenol at a very short radiation time. The reaction was found to follow the first order kinetics and was influenced by the pH, the input concentration of H202 and the dosing amount of the Ti02 photocatalyst. The results indicate maximum 74.6% and 79.8% degradation of phenol and chlorophenol respectively within 90 minutes of radiation time. The experimental results showed that the optimum conditions were obtained at a pH value of 4, with H202 concentration ranging from 200-550 mIlL, and Ti02 dosing ranging from 1-2 gIL for UVlll 202ITi02 combined system. The reactions were accompanied by the reduction of COD and generation of cr ion, which reached its maximum value at a short reaction time. Finally a rough comparison of energy consumption shows that UVlll 202ITi02 process reduced the energy consumption by 40-50% compared with the UV 111 202 and UV lTi02 processes.

Abstract-The present investigation focuses on testing the adsorptive behaviour of laboratory synthesized titania nanofibers towards Hg(II) and Pb(II) in the aqueous system. The BET analysis confirmed that the electrospinned nanofibers were confirmed to possess a large surface area of 740 m 2 /g. The fiber mats were analysed by EDX, which confirmed the adsorption of the metals on the fiber surface. SEM revealed the smooth morphology and continuous nature of the fibers. The effect of pH, contact time and adsorbent dose is compared for both the metals. At the most optimized conditions, highest uptake of 95.5% was observed for 0.01 mg/L Hg(II) concentration while it was 83.8% for 0.5 mg/L Pb(II) concentration. Since the rate limiting steps in adsorption are of vital importance in order to define the rate parameters for design purposes, the present study takes into account Weber and Morris and Boyd mass transfer diffusion models for both Hg(II) and Pb(II) adsorption on titania nanofibers. The equilibrium data were then analyzed using Langmuir and Freundlich sorption models and the characteristic sorption parameters for each isotherm were determined. The discussion also focuses on few of the recently used adsorbents for heavy metal uptake and their comparison with the present study.Index Terms-Adsorption, heavy metals, isotherm, mass transfer, nano adsorbent.
