Brand engagement in self-concept (BESC), value consciousness and brand loyalty: a study of generation Z consumers in Malaysia Ahmed Rageh Ismail, Bang Nguyen, Junsong Chen, T.C. Melewar, Bahtiar Mohamad Young Consumers ISSN: 1747-3616 Publication date: 31 March 2020 Reprints & Permissions PDF (616 KB) Abstract Abstract Purpose This study aims to examine the relationship between brand engagement in self-concept (BESC), value consciousness (VC) and brand loyalty among Generation Z consumers. In addition, the study aims to segment the Generation Z consumers based on BESC and VC and examine the differences between the segments. Design/methodology/approach A self-administered questionnaire was developed and administered to a sample of 346 undergraduate students in Malaysia. The hypothesized structural models are tested using partial least squares structural equation modeling. The study also uses cluster analysis to segment the Generation Z consumers. Findings The results reveal that among Generation Z consumers both BESC and VC have a positive effect on brand loyalty. Additionally, the mediation analysis established that BESC plays a mediating role in the relationship between VC and brand loyalty. The study also identified four consumer groups – attentive group, dedicated group, prospective group and switchers group. Furthermore, consumer classification according to BESC can be used by marketers and managers in marketing strategy development. Originality/value The study has originality and value in developing and testing a new model linking BESC with VC and brand loyalty. Further, market segmentation on the basis of BESC and VC has been rarely studied. Even less, has been studied among Generation Z consumers and this study fills this important gap.
A model for malaysian work value to improve level of work value among Malaysian graduate
(Hampstead Psychological Associates, 2020-02) Mohamad, B.a; Zulkepli, J.b; Ismail, A.R; Bakar, H.A
Work values are the beliefs and ideas that are related to one’s occupation. These values are eventually used as guiding principles in career choice. Previous research examined work values and its impact or some relevant constructs such as affective commitment, organizational identification and self-efficacy. However, those relationships haven’t been collectively integrated and empirically tested in a theoretical model, nor have they been empirically tested. Therefore, this study aims to assess the influence of Malaysian Work Value Model (MWVM) on cooperative communication, affective commitment, organizational identification and self-efficacy. Latent composite structural equation modeling was used to test the hypothesized model. Finally, recommendations will be provided for the public and private universities to help them in developing their course learning outcome in order to enhance student’s work values and increase the employability rate. © 2020, Hampstead Psychological Associates
Rotor–stator hydrodynamic cavitation reactor for intensifcation of castor oil biodiesel production

Nowadays, the intensifcation of the production of biodiesel from non-edible oil crops is mandatory to overcome petrol-fuel depletion and environmental pollution. For the frst time, enhanced biodiesel production from castor oil via rotor–stator hydrodynamic cavitation has been studied in this work. Response surface methodology based on one-factor-at-a-time design of experiments was employed for modelling and optimizing the biodiesel yield and the decrease in feedstock viscosity, density, and total acid number (TAN). The predicted optimum parameters of 8.15:1 methanol:oil (M:O), 1499 rpm, 29.38 min, 48.43 °C, and a KOH catalyst concentration of 0.74 wt.% resulted in a 96% biodiesel yield with a concomitant decrease in viscosity, density, and TAN of approximately 95%, 5.12%, and 90.02%, respectively. According to the results of the breakthrough kinetic calculations, the reaction is pseudo-second order, with the activation energy, frequency factor, and reaction rate constant being 0.23 M−1 min−1, 18.77 kJ/mol, and 6.32 M−1 min−1, respectively. The fuel properties of the produced biodiesel and bio-petro-diesel blends were good, comparable to international standards and the marketed Egyptian petro-diesel.
