Abstract

Purpose

There is a strong inducement to develop new inorganic materials to substitute the current industrial pigments, which are known for their poor ultraviolet absorbent and low photoluminescence (PL) properties. The purpose of this paper is to invent a better rare-earth-based pigment material as a spectral modifier with good luminescence properties to enhance the spectral response for photovoltaic panel application.

Design/methodology/approach

Different phosphor samples made of nano-calcium carbonate (CaCO3) with varied wt.% of the dopant Dysprosium doped calcium borophosphate (CBP/Dy) as (W0 – 0%, W1 – 3,85%, W2 – 7.41%, W3 –10.71% and W4 –13.79%) were prepared via the solid-state diffusion method at 600 °C for 6 h using a muffle furnace. The structural, morphological and luminescence properties of the CaCO3:CBP/Dy powder samples were examined using scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and PL test.

Findings

The XRD, SEM and FTIR results verified the crystalline formation, morphological behaviour and vibration bonds of synthesized CBP/Dy-doped CaCO3 powder samples. XRD pattern revealed that the synthesized powder samples exhibit crystalline structured materials, and SEM results showed irregular shape and porous-like structured morphologies. FTIR spectrum shows prominent bands at 712, 874 and 1,404 cm−1, corresponding to asymmetric stretching vibrations of CO32− groups and out-of-plane bending. PL characterization of CBP/Dy-doped CaCO3 (sample W) shows emission at 427 nm (λmax) under the excitation of 358 nm. The intensity of PL emission spectra drops due to the concentration quenching effect, while the maximum PL intensity is observed in the W3 phosphor powder system.

Research limitations/implications

This phosphor powder is expected to find out the potential application such as a spectral modifier which is applied to match the energy of photons with solar cell bandgap to improve spectral absorption and lead to better efficiency.

Originality/value

The introduction of a nano-CaCO3:CBP/Dy hybrid powder system with good luminescence properties to be used as spectral modifiers for solar cell application has been synthesized in the lab, which is a novel attempt.

Abstract

Purpose

The design process of a bio-model involves multiple factors including data acquisition technique, material requirement, resolution of the printing technique, cost-effectiveness of the printing process and end-use requirements. This paper aims to compare and highlight the effects of these design factors on the printing outcome of bio-models.

Design/methodology/approach

Different data sources including engineering drawing, computed tomography (CT), and optical coherence tomography (OCT) were converted to a printable data format. Three different bio-models, namely, an ophthalmic model, a retina model and a distal tibia model, were printed using two different techniques, namely, PolyJet and fused deposition modelling. The process flow and 3D printed models were analysed.

Findings

The data acquisition and 3D printing process affect the overall printing resolution. The design process flows using different data sources were established and the bio-models were printed successfully.

Research limitations/implications

Data acquisition techniques contained inherent noise data and resulted in inaccuracies during data conversion.

Originality/value

This work showed that the data acquisition and conversion technique had a significant effect on the quality of the bio-model blueprint and subsequently the printing outcome. In addition, important design factors of bio-models were highlighted such as material requirement and the cost-effectiveness of the printing technique. This paper provides a systematic discussion for future development of an engineering design process in three-dimensional (3D) printed bio-models.

Abstract

Purpose

The purpose of this paper is to determine the safety of substituting the first day post-operative review after routine cataract surgery (phacoemulsification) with a telephone survey.

Design/methodology/approach

Prospective non-randomised cohort study. A standardised questionnaire of five common ocular symptoms (general condition, vision, eye pain, headache, nausea or vomiting) was administered by a trained nurse on the first post-operative day. The patients were reviewed in clinic two to 14 days later. Patient charts were retrospectively reviewed for complications (endophthalmitis, raised intra-ocular pressure, wound leaks and uveitis) requiring deviation from standard treatment.

Findings

Over 13 months, 256 eyes of 238 patients underwent uncomplicated phacoemulsification by four consultant surgeons. Only one patient reported poor general condition, blurred vision and eye pain. She was subsequently found to have corneal oedema and raised intra-ocular pressure when recalled for an earlier review. Best corrected visual acuity better than 20/40 was achieved in 80.5 per cent of patients. There were no other post-operative complications noted from medical records review.

Research limitations/implications

Non-randomised nature, skewed surgical expertise, lack of a control group and patient experience data. In all, 22 patients (9.2 per cent) were also uncontactable for the telephone interview.

Practical implications

A nurse-administered telephone survey seemed to be a safe and effective alternative to first day post-operative review after routine phacoemulsification. The survey also enabled the detection of serious post-operative complications. The first day post-operative hospital visit may be safely substituted in a selected patient population with greater patient convenience achieved and liberation of clinic resources.

Originality/value

This is the first study which utilises a standardised questionnaire as a form of post-operative review in an Asian population.

Abstract

Purpose

The purpose of this paper is to examine the impact of preparation level of heirs and the relationship between family and business members on the performance of family business in small- and medium-sized enterprises (SMEs) in Malaysia.

Design/methodology/approach

A quantitative research design involving the use of a survey questionnaire was implemented to investigate the influences of succession planning factors on the performance of family business in SMEs. The survey was conducted on 50 family business successors in Malaysian SMEs.

Findings

The result showed that the two studied factors – preparation level of heirs and the relationship between family and business members – have a positive impact on the performance of family business.

Research limitations/implications

The research concentrated on the performance of family business in SMEs in Malaysia’s southern region. The generalization therefore must be made very cautiously to the overall Malaysian SMEs.

Practical implications

The findings help family businesses to better understand the importance of the preparation level of heirs and the relationship between family and business members on business performance. This study shows the importance of key factors influencing succession planning so that the successor to the family business can bring the family firm to the next stage of success.

Originality/value

This study serves as a reference or guide for the management of family businesses to better understand the important factors for effective succession planning. It considers the best possible preparation and family-related factors affecting the end results of business, particularly in Malaysian SMEs.

Abstract

Purpose

Mango seed, an agricultural food (agri-food) waste obtained during mango processing is generally discarded and causes environmental stress. In the present study, mango kernel was processed into flour and incorporated into macaron formulation. This study aimed to investigate the antioxidant potential, physicochemical properties, and sensory qualities of macaron after substitution of almond flour (AF) with 0% (control, MC-0), 20% (MC-20), 40% (MC-40), 60% (MC-60), 80% (MC-80) and 100% (MC-100) (w/w) of mango kernel flour (MKF).

Design/methodology/approach

Sensory evaluation was conducted using a nine-point hedonic scale (n = 90 young adults) to evaluate the acceptance towards MC-0 (control), MC-20, MC-40, MC-60, MC-80 and MC-100 macaron shells (without mango-flavoured ganache). The most preferred formulated and control macarons were subjected to proximate analyses according to the methods of Association of Official Analytical Chemists for moisture, ash, and protein, and American Oil Chemists' Society for fat. Carbohydrate content was estimated by difference. Physical analyses such as colour, pH and water activity (aw) were performed using various instrumental techniques. Antioxidant activity of all macaron shell formulations was accessed using 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity (DPPH-RSA). Sensory evaluation was repeated using a five-point hedonic scale to determine the acceptance of the most preferred macaron (with mango-flavoured ganache) among consumer panels of all age groups (n = 80).

Findings

The first sensory acceptance test revealed that macaron shell with 40% MKF substitution (MC-40) was the most preferred formulation among young adults aged 18–35 years old. Moisture and ash contents between MC-0 and MC-40 were found to be similar (p > 0.05), while significant differences (p < 0.05) were observed for the fat and protein contents. Antioxidant activity increased proportionally with increasing MKF substitution and exhibited significant improvement (p < 0.05) in MC-40. Approximately 93% of the panellists expressed their liking towards MC-40 in the second sensory acceptance test. Overall, this study demonstrated that 40% MKF substitution in macaron improved its antioxidant performance without compromising consumers' acceptance.

Originality/value

This innovative research features the incorporation of MKF in the development of an economical and healthier macaron. The results constitute industrial relevant findings pertaining to its application feasibility and nutritional properties. This research has contributed knowledge to the existing literature as well as benefitted food manufacturers to develop value-added products that could meet the needs and expectations of interested parties, including consumers, governmental organisations, health-cautious advocates and healthcare providers.

Abstract

Purpose

The purpose of this paper is to investigate the interaction effect of placement characteristics and emotional experiences on consumers’ recognition of placed brands. Brand recognition is a fundamental step in the consumer’s decision-making journey.

Design/methodology/approach

The authors developed a research model based on emotional process theory and cognitive capacity theory incorporating placement characteristics, emotional experiences and brand recognition. An experimental study of 110 young Chinese consumers was conducted to test the research model.

Findings

The findings indicated that all three placement characteristics (prominence, serial positions and plot connection) had significant effects on brand recognition, as suggested in previous research. The effect of emotional experiences on brand recognition was comparatively less prominent. Placement characteristics and emotional experiences also interacted to influence the recognition of placed brands.

Originality/value

This study shows the role of emotional experiences and their interaction with placement characteristics on brand recognition, which has yet to be examined. The conceptual model contributes to the product placement literature by suggesting that both cognitive and emotional processing are important for brand recognition. The findings provide useful insights for marketers in designing effective product placement strategies.

Abstract

Purpose

This study aims to extend the literature on marketing communications by exploring the effect of placing products in humorous scenes. It aims to ascertain the prevalence of placement scenes associated with humor in television programs and the effect of humor on brand persuasiveness.

Design/methodology/approach

The study used a two-phase research process. A content analysis of prime-time television programing was conducted to map the relative prevalence of brands placed in humorous contexts and for the selection of research stimuli. This was followed by a large-scale experimental study of 1,100 television viewers in Hong Kong with real stimuli that had been digitally manipulated.

Findings

The study found that a humorous context did enhance recall of placed brands but its effect on brand attitudes was mediated by audience involvement in the viewing and moderated by psychological trait reactance. Interestingly, and in contrast to conventional advertising, placing brands in a humorous context led to lower involvement in the viewing, which, in turn, resulted in lower brand attitudes. Individuals with low trait reactance were more positive toward brands placed in a non-humorous context than individuals with high trait reactance while individuals with high trait reactance were more positive toward brands placed in a humorous context, though the difference was less prominent.

Research limitations/implications

The findings help to illustrate when and how a humorous context contributes to the recall of and attitudes toward placed brands.

Practical implications

The results also facilitate marketers and program producers to choose the best placement context and design more effective placement strategies.

Originality/value

This research is the first to empirically examine the effect of a humorous context on the unaided recall of and attitudes toward brands placed in television programs.

Abstract

Purpose

The purpose of this study contributes to literature on marketing communications by empirically contrasting the effectiveness of a new form of covert promotions (product placement in recipes) and an overt promotion (traditional advertisement). The mediating role of perceived believability of promotional materials and the moderating roles of advertising skepticism and brand awareness were examined based on a conceptual model.

Design/methodology/approach

A Web-based experiment with 2 (form of promotion: overt versus covert) × 2 (brand awareness: low versus high) between-subjects full factorial design was used. A public sample of 537 participants had participated in the study. The conceptual model was further tested on 106 participants using stimuli of a fictitious brand.

Findings

A two-stage moderated mediation analysis shows that the perceived believability of promotional materials was a significant mediator of the form of promotion and brand evaluations. Consumers showed a higher level of believability toward covert promotion, which, in turn, led to more positive evaluations of the promoted brand. Advertising skepticism and brand awareness were found to significantly moderate the relationship between form of promotion and attitudes toward the promoted brands. A similar pattern of results was obtained when stimuli of a fictitious brand were used.

Originality/value

This research addresses an important issue in marketing communication and extends the understanding of the perception of overt and covert promotions by examining the underlying mediating and moderating variables, which have rarely been explored before. The results guide marketers in developing effective marketing communication strategies for well-known, less well-known and even new brands. It also directs policymakers to consider whether integrated branded content in recipes should be disclosed to protect consumers from surreptitious promotions, which may help to lower consumers’ skepticism toward advertising in the long run.

Abstract

Purpose

Expenditures on beauty, fitness and body shaping by females have increased significantly in recent years. Most previous studies examined this from the psychological perspective of self-acceptance and self-liking. However, this phenomenon may also have social implications. This study aims to provide a profound understanding of the social environment for female professionals as well as actionable insights for the government and social institutions.

Design/methodology/approach

A research model was developed based on impression management and social identity theories incorporating impression management motives, impression construction consumption and social identity. A survey study of 419 Chinese female professionals was conducted to test the research model.

Findings

This study surveyed 419 Chinese female professionals and found that impression management motives significantly drove female professionals to spend on their faces and bodies for impression construction, which in turn contributed to the enhancement of their social identities in three dimensions: relational identity, public identity and collective identity.

Originality/value

In a male-dominated society, it has become a norm that females should be cautious about their facial appearance and body shape. Females are often forced to consume to attain physical attractiveness and to construct a favorable social image. This study shows that consumption for impression construction has become a frequently used strategy for impression management and identifies key areas of societal concern.

Abstract

Purpose

This study aims to offers a deeper insight into bank selection of Ghanaian students so as to offer bank managers the opportunity to tailor‐measure programmes aimed at attracting and retaining customers.

Design/methodology/approach

The study employed both qualitative and quantitative methods to investigate the problem. The “drop and pick” convenience sampling method adopted resulted in 223 completed questionnaires. The mean ranking and factor analysis methods were employed to identify the major factors that influence the respondent bank selection.

Findings

Over all, student customers consider image, attitude and behaviour of staff, core service delivery and technology‐related factors as the major issues that influence consumers' decision to open and maintain an account.

Research limitations/implications

The limitation of the study relates to the student population used for the study, which limits the generalisability of the findings. The study, however, contributes to the academic knowledge of bank selection and provides insights into the critical factors considered by sample students in their bank selection decisions.

Practical implications

In a market where consumers respond differently to a marketing offer, market segmentation becomes a necessity and therefore differences in male and female consumers' selection criteria emanating from this study provide an excellent opportunity for the banks to adopt segmentation‐based strategies to serve the customers.

Originality/value

In this paper, gender and educational level provide a deeper understanding of bank selection criteria among the Ghanaian bank customers. The four constructs can be used by bank management as bases for designing marketing strategies to deliver efficient service, and engage in relationship marketing practices to attract and retain customers.
