Measuring personality congruency effects on consumer brand intentions in celebrity-endorsed brands
Authors: Arora Nilesh , Prashar Sanjeev , Tata Sai Vijay , Parsad Chandan 
Published: February 2021

PurposeBrand managers frequently use well-known celebrities to position their brands and capture consumers’ attention to improve the brand’s market share. The attachment of a celebrity with a brand creates a human image for a brand and helps in personifying its image. The consumer perceives the brand as an individual and relates his personality, as well as the personality of the celebrity with that of the brand. It becomes pertinent for marketers to understand how brand-celebrity personality congruence and brand-consumer personality congruence affect the brand reputation, uniqueness and purchase intentions. Thus, the purpose of this study is to understand the relationship between the two personality congruence aspects – brand & celebrity personalities and brand & consumer personalities, and their impact on the reputation of the brand and its uniqueness. Further, the paper aims to examine the impact of the brand reputation and brand uniqueness on purchase intentions.Design/methodology/approachThe present study uses Aaker’s five-factor personality scale to study the personality congruence effects on brand reputation, brand uniqueness and purchase intentions. The literature review was carried out to categorize factors related to celebrity personality, brand personality and consumer personality. The data for this study was collected through questionnaires from 1,235 respondents. In the first step, congruencies between celebrity, brand and consumer personality were determined. This was followed by a two-stage structural equation modelling for assessing the model fit and testing the hypotheses.FindingsFrom the study results, it is observed that brand-celebrity congruency influences brand reputation and brand uniqueness. However, brand-consumer congruency had an effect only on brand reputation and not on brand uniqueness. Both brand reputation and uniqueness have favourable impact on consumers purchase intentions.Originality/valueThis study contributes to the existing literature on celebrity endorsement by extending the discussion with personality-based congruence. The research deciphered two aspects of identification, i.e. consumer-brand personality congruence and brand-celebrity congruence. The paper hypothesized the favourable association between brand personality and consumer personality congruence and brand uniqueness. However, it was observed that brand personality-consumer personality identification had an insignificant influence on brand uniqueness. This is contrary to the findings of some studies in the literature. Further investigation of this relationship in the future may add a new dimension to the identification context.
Exploring lack of closure as a brand transgression
Authors: Burgess Jacqueline , Jones Christian 
Published: February 2021

Purpose
This study aims to contribute to research into narrative brands by investigating if the lack of closure in the ambiguous season two’s ending of the Australian television series, Wanted, constituted a brand transgression.

Design/methodology/approach
Comments on posts about Wanted from social media accounts associated with the series were downloaded and analysed using thematic analysis informed by non-participatory netnography.

Findings
Audiences found the ambiguous ending of Wanted season two disappointing and it did not fulfil implied promises and their expectations, which fits the description of a brand transgression, and so they engaged in behaviours indicative of a brand transgression such as spreading negative word of mouth online. The ambiguous ending could have been a cliff-hanger to lead into a third season that was not guaranteed when the final episode aired, or the ending for the entire series. Although a third season was eventually made and positively received by audiences, viewer numbers declined by nearly a third, illustrating the importance of brand management for narrative brands.

Practical implications
This research has implications for the creators of television series, particularly if they do not know if it will be renewed. Not providing audiences with their expected closure can constitute a brand transgression and damage the narrative brand’s residual brand equity and potential earnings from streaming or a revival at a later date.

Originality/value
Prior research has focused on audiences’ responses to definitive endings, rather than ambiguous endings, which is the focus of this research. Furthermore, narrative brands are still an under-researched context.

Published: February 2021

PurposeA key strategy in the policy of saw millers and artisanal millers supplying the domestic market with legal and sustainable lumber is the transformation of chainsaw operators into legal artisanal millers to stop the production of illegal timber and supply only authorized wood to local trade points. The challenge, however, is how to develop the concept of its viability and acceptability to the chainsaw operators. Specifically, existing and potential investors’ knowledge about the possible costs and revenue is non-existent. This study aims to examine the financial and economic viability of the artisanal timber milling (ATM) business in rural Ghana.Design/methodology/approachUsing data from three operational artisanal milling companies in Ghana, net present value, internal rate of return, profitability index and payback period were used in analyzing the viability of artisanal timber milling.FindingsThe results showed that the ATM business is financially and economically viable, attractive and profitable.Social implicationsATM business has the potential to create more jobs in the timber industry, reduce illegalities in the forestry sector and improve the living standard of individuals used by the sector.Originality/valueAs part of ATM’s medium and long-term strategies, the study encourages stakeholders to consider assisting existing and potential actors who have the passion to venture into this business to acquire concessions and financial support from financial institutions.

Published: February 2021

PurposeAlthough there is a large body of literature available on the foundations of workplace learning (WPL), little is known about designated research methods that systematically combine intervention, design and learning at work. The purpose of this study is to propose action design research as an alternative method for organizing WPL in general and facilitating pedagogically rich activities in particular.Design/methodology/approachThis research used a case study approach to focus the action design research method and exemplify its utility through two case studies that emphasize WPL in general and how the method can be used to facilitate pedagogically rich activities in particular.FindingsThe results of the case studies indicate that the action design research method had a significantly positive effect on organizing WPL in organizations systematically, as well as creating a narrative that structures the research process and its outcomes.Originality/valueThe findings help scholars that are in need of organizing WPL research in a systematic way. The findings do also help practitioners in organizations to solve real-world problems and develop new knowledge jointly together with scholars. Consequently, the findings contribute to the existing literature by exemplifying how to facilitate pedagogically rich activities and disseminate the outcomes of doing so in a formalized way.

PurposeThe purpose of this study was to prepare water-based binders, which aimed to avoid printhead blockage and to improve dimensional accuracy of inkjet 3D printing (3DP) technology, and a feasible algorithm of full-color printing was realized.Design/methodology/approachA self-developed color 3D printer was made by using a piezoelectric printhead of Epson Dx-5. Several water-based binders and corresponding gypsum composite powders were prepared, and the optimum binder-powder assembly was then determined through elementary adhesive testing and roller paving testing. Full-color printing was implemented based on halftoning algorithms that used different threshold matrices for different ink channels, and the performances of various algorithms were evaluated in terms of both subjective and objective indices.FindingsThe optimum binder-powder assembly can solve the jamming problem of printhead and realize agreeable dimensional accuracy with the relative error less than 2.5% owing to the satisfying boundary diffusion control ability. And the determined halftone algorithm was verified to be agreeable for 3D color printing.Originality/valueThe prepared approach of water-based binders and gypsum composite powders can be applied to similar 3DP systems even if different materials are introduced. And the used halftone algorithms provide feasible guidelines to the implementation of 3D full-color printing.
Challenges and opportunities concerning Environmental Goods (EGs): a case study and business perspective
Authors: Ahsan Md Rajibul 
Published: February 2021

PurposeGiven the current global climate change concerns, environmental goods (EGs) exported from developing countries have been declining in recent years despite the growing economic importance of these nations. Researchers believe that the problem lies in the nature of technology and border-related constraints.Design/methodology/approachThis research work considers a relatively modern approach known as the “stochastic frontier gravity-type model” to examine opportunities and challenges involving Bangladesh EGs exports.FindingsIt is evident that Bangladesh, despite its close links to the other East Asian economies, has not realized the true potential of EGs exported between 2001 and 2015.Originality/valueThis study highlights the removal of border-related constraints that will improve the country’s exports. The findings will make it possible to explain the constraints of the export of environmental goods.

Authors: Kumar Navin , Walia Ravinderjit Singh , Angra Surjit 
Published: February 2021

Purpose
The purpose of this study is to develop jute-glass hybrid fibre reinforced polyester-based bio-composites using an indigenously developed pultrusion set-up and to present a detailed discussion on their mechanical characterization.

Design/methodology/approach
The work was carried out to observe the hybridization effect of natural and synthetic fibres in combination with hybrid fillers loading mainly on strength and other properties. The used hybrid fillers were a combination of 9 Wt.% of carbon black%, 6 Wt.% of eggshell ash powder and 6 Wt.% of coconut coir ash powder. A lab-based developed pultrusion set-up was used to develop these hybrid GJFRP composites of 1,500 mm length. The developed composites were tested for tensile strength, compressive strength and impact strength.

Findings
The maximum tensile, compressive and impact strength obtained are 88.37 MPa, 56.13 MPa and 731.91 J/m from 9 Wt.%, 9 Wt.% and 0 Wt.% of hybrid fillers loading, respectively. Breaking energy was found maximum as 7.31 J in hybrid glass-jute hybrid fibre reinforced plastic composites with no filler loading and it was observed that filler loading was decreasing the impact strength of developed hybrid composites. Shrinkage and its variations in the diameter of the finally developed cylindrical shape composites were observed after cooling and solidification. Scanning electron microscopy was used to observe the internal cracks, bonding of fibres and resin, voids, etc.

Originality/value
Development of hybrid filler based novel eco-friendly bio-composites and its experimental investigation on the impact strength, tensile strength and compressive strength has not been attempted yet.

Abstract

Transmission is a key component of a pathogen's life history, but it is often difficult to obtain reliable ecological estimates of the dominant mode(s) of transmission and how host traits, such as sex, influence transmission dynamics.

Here, we have developed a robust system pairing the use of semi‐natural populations of house mice Mus musculus with modern molecular viral titering approaches to evaluate the transmission dynamics of Friend Virus Complex (FVC).

Semi‐natural populations were founded with female and male mice that were either ‘index’ (initially infected via intraperitoneal injection) or ‘contact’ (uninfected at the start of experiment). Three experimental population designs were implemented: female index only, male index only and both female and male index.

Utilizing these enclosures, we found male–male transmission to be the predominant mode of transmission, with low rates of horizontal female transmission and no evidence of vertical transmission. Additionally, contact males that became infected harbour higher titres than females while suffering a similar amount of spleen enlargement; this, paired with a strong correlation between titre and spleen size in males, and no correlation in females, indicates FVC viral dynamics differ between the sexes.

Lastly, natural transmission may be an impediment to FVC replication as infected contact animals have a lower viral titre than index animals. These results illuminate the complex life history of murine leukaemia viruses and demonstrate the important role of host sex on pathogen transmission dynamics.

Published: February 2021

Policy Points
Several intergovernmental organizations (Organisation for Economic Co‐operation and Development, World Health Organization, United Nations) are urging countries to use well‐being indicators (e.g., life satisfaction) in addition to traditional economic indicators when making important policy decisions.
As the number of governments implementing this new approach grows, so does the need to continue evaluating the health and well‐being outcomes we might observe from policies aimed at improving life satisfaction.
The results of this study suggest that life satisfaction is a valuable target for policies aiming to enhance several indicators of psychosocial well‐being, health behaviors, and physical health outcomes.
ContextSeveral intergovernmental organizations (Organisation for Economic Co‐operation and Development, World Health Organization, United Nations) are urging countries to use well‐being indicators (e.g., life satisfaction) in addition to traditional economic indicators when making important policy decisions. As the number of governments implementing this new approach grows, so does the need to continue evaluating the health and well‐being outcomes we might observe from policies aimed at improving life satisfaction.MethodsWe evaluated whether positive change in life satisfaction (between t0;2006/2008 and t1;2010/2012) was associated with better outcomes on 35 indicators of physical, behavioral, and psychosocial health and well‐being (in t2;2014/2016). Data were from 12,998 participants in the University of Michigan's Health and Retirement Study—a prospective and nationally representative cohort of US adults over age 50.FindingsParticipants with the highest (versus lowest) life satisfaction had better subsequent outcomes on some physical health indicators (lower risk of pain, physical functioning limitations, and mortality; lower number of chronic conditions; and higher self‐rated health) and health behaviors (lower risk of sleep problems and more frequent physical activity), and nearly all psychosocial indicators (higher positive affect, optimism, purpose in life, mastery, health mastery, financial mastery, and likelihood of living with spouse/partner; and lower depression, depressive symptoms, hopelessness, negative affect, perceived constraints, and loneliness) over the 4‐year follow‐up period. However, life satisfaction was not subsequently associated with many specific health conditions (i.e., diabetes, hypertension, stroke, cancer, heart disease, lung disease, arthritis, overweight/obesity, or cognitive impairment), other health behaviors (i.e., binge drinking or smoking), or frequency of contact with children, family, or friends.ConclusionsThese results suggest that life satisfaction is a valuable target for policies aiming to enhance several indicators of psychosocial well‐being, health behaviors, and physical health outcomes.
Encapsulation of oyster protein hydrolysates in nanoliposomes: Vesicle characteristics, storage stability, in vitro release, and gastrointestinal digestion

Published: February 2021

AbstractIn this study, oyster protein hydrolysates (OPH) were obtained from oyster meat by hydrolysis using animal complex proteases and then encapsulated in nanoliposomes. The physicochemical properties, stability, and digestive characteristics of OPH‐loaded nanoliposomes were evaluated. The average size and zeta potential ranged from 95.64 to 102.39 nm and from −47.36 to −36.43 mV, respectively. Liposomes containing 4 mg/mL OPH had the highest encapsulation efficiency (74.53%). Fourier transform infrared spectroscopy analysis showed that effective ionic complexation and hydrogen bonding existed between phospholipid and peptides. The liposomes exhibited the highest stability when stored at 4 °C. Liposomal encapsulation may protect the antioxidant peptides in OPH during storage and simulated digestion. The nanoliposomes were not hydrolyzed and the structural integrity was maintained in gastric digestion, but exhibited lower stability in the intestinal phase. A prolonged release of OPH from nanoliposomes was also observed as compared with free OPH. Liposome containing protein hydrolysates may be used as a formula in functional foods.Practical ApplicationThis study provides some useful information on the application of oyster protein hydrolysates or peptides in functional foods. The incorporation into liposomes may protect the hydrolysates against harsh conditions during storage and digestion, and also prolong the release time.
Studies on functional properties of wheat starch in the presence of Lepidium perfoliatum and Alyssum homolocarpum seed gums
Authors: Rahimi Ghazale , Hedayati Sara , Mazloomi Seyed Mohammad 
Published: February 2021

AbstractThis study was performed to investigate the influence of Lepidium perfoliatum seed gum (LPSG) and Alyssum homolocarpum seed gum (AHSG) on functional properties of wheat starch. Various concentrations of gums (0.25%, 0.5%, 0.75%, and 1% dry starch weight basis) were added to wheat starch, and their influences on water absorption, pasting properties, gel strength, freeze–thaw stability and color parameters were investigated. The results showed that both gums improved water absorption, freeze–thaw stability, pasting parameters, gel hardness, gumminess, and chewiness whereas springiness was not affected and cohesiveness was decreased by the incorporation of gums and LPSG more effective than AHSG. Color parameters were also affected by the concentration of gums. The L value decreased whereas a value and b value increased in the presence of both gums. However, the changes were more obvious in samples containing LPSG.Practical ApplicationStarch is one of the most important carbohydrate materials in the food industry. However, native starch has shortcomings, such as sensitivity to shear or syneresis that limit its applications in food processing. Incorporation of hydrocolloids is an effective strategy to improve functional properties of starch. LPSG and AHSG are two novel sources of hydrocolloids which can be used to modify the properties of starch in food products.
Impact of polymerized whey protein/pectin thickening (PP) system on physical properties and volatile compounds of goat milk kefir mild and kefir

Published: February 2021

AbstractPolymerized whey protein and low‐methoxyl pectin were used as thickening agents in fermented dairy food formulations. Effects of polymerized whey protein and pectin (PP) system on particle size distributions, rheological properties, molecular weight distributions of polysaccharides, microstructures, and volatile compounds of goat milk kefir mild and kefir were investigated. Clustering analysis indicated that the PP system addition could increase the particle size distributions and rheological properties of both kefir products. Molecular weight distributions of polysaccharides shown that an intermolecular aggregation occurred between pectin and exopolysaccharides (produced by microorganisms from starter cultures). Micrographs suggested that polymerized whey protein interacted with casein network to form a dense structure. Meanwhile, PP system did not change the characteristics flavor of goat milk kefir mild and kefir. Results indicated that the PP system may be a good combination to improve the physical properties of kefir products.Practical ApplicationGoat milk kefir has gained more and more attention due to its specific flavor and functional properties. However, poor texture of milk curd limits the consumption of fermented goat milk. As a new combination of thickening agents, PP system could specifically improve the particle size distributions and rheological properties of fermented goat milk. And the characteristic flavor of goat milk kefir was not changed. Results indicated that PP system can be used as thickening agents for formulations of different fermented goat milk products.
A model for analyzing clustered occurrence data
Authors: Hwang Wen‐Han , Huggins Richard , Stoklosa Jakub 
Published: February 2021

AbstractSpatial or temporal clustering commonly arises in various biological and ecological applications, for example, species or communities may cluster in groups. In this paper, we develop a new clustered occurrence data model where presence–absence data are modeled under a multivariate negative binomial framework. We account for spatial or temporal clustering by introducing a community parameter in the model that controls the strength of dependence between observations thereby enhancing the estimation of the mean and dispersion parameters. We provide conditions to show the existence of maximum likelihood estimates when cluster sizes are homogeneous and equal to 2 or 3 and consider a composite likelihood approach that allows for additional robustness and flexibility in fitting for clustered occurrence data. The proposed method is evaluated in a simulation study and demonstrated using forest plot data from the Center for Tropical Forest Science. Finally, we present several examples using multiple visit occupancy data to illustrate the difference between the proposed model and those of N‐mixture models.
