The present study explores the antecedents and outcome of job embeddedness. The antecedents are: level of control over work hours and felt obligation. The outcome is proactive customer service performance. Using self-administered questionnaires, 163 paired responses were gathered from frontline employees and their supervisors/managers in 16 hotels/resorts with a rating of four and five stars in Malaysia. Frontline employees responded to the questions on level of control over work hours, felt obligation and job embeddedness (on-the-job and off-the-job). Supervisors/managers responded to the questions on their employees' proactive customer service performance. The salient findings are: (1) Level of control over work hours and felt obligation have significant relationships with on-the-job embeddedness; (2) On-the-job embeddedness has a significant relationship with proactive customer service performance; (3) On-the-job embeddedness mediates the relationship between felt obligation and proactive customer service performance; and (4) Off-the-job embeddedness has a significant relationship with on-the-job embeddedness.

Nishanth Chemmangattuvalappil (2015): Luffa acutangula peel as an effective natural biosorbent for malachite green removal in aqueous media: equilibrium, kinetic and thermodynamic investigations, Desalination and Water Treatment, A B S T R A C TLuffa acutangula peel (LAP) was evaluated as an inexpensive natural biosorbent for the removal of malachite green (MG), a cationic dye, in batch mode. The effects of process parameters including initial pH, dosage, initial concentration, temperature and contact time on MG biosorption were assessed. Experimental data were analysed by the Langmuir, Freundlich, Temkin and Dubinin-Radushkevich models. The results showed that MG biosorption was well represented by the Langmuir model with a maximum sorption capacity of 69.64 mg/g. The pseudo-first-order and pseudo-second-order kinetic models were used to establish the biosorption kinetic. A good correlation of data with the pseudosecond-order model suggested the involvement of chemisorption in the process. Further kinetic analysis indicated intraparticle diffusion as one of the rate limiting steps. The biosorption process was endothermic (ΔH˚= 0.332-12.64 kJ/mol) and spontaneous (ΔG˚= −20.81 to −14.28 kJ/mol). Overall, the findings suggested that LAP can be an effective biosorbent for the removal of MG in aqueous solution.
