Authors: Bilal Muhammad , Meera Ahamed Kameel Mydin , Abdul Razak Dzuljastri 
Published: March 2019

Purpose
This study aims to examine the issues and challenges in contemporary affordable public housing schemes and proposes an alternative affordable public housing model for low- and middle-income households in Malaysia.

Design/methodology/approach
The paper applied qualitative research method. Semi-structured in-depth interviews with four government officials were conducted to understand the provision, framework and working mechanism of selected affordable public housing schemes. A focus group with nine participants was conducted with low- and middle-income households to validate pertaining residential issues and problems in affordable public housing schemes.

Findings
The overall findings reveal that the growing plights of unaffordability, poor maintenance and mismanagement have undermined the performance of affordable public housing schemes in Malaysia. The paper indicates that Islamic Public–Private Housing Co-operative Model (IPHCM) possibly has a comparative advantage in its design and operation and therefore can be implemented as an alternative model to address these issues in contemporary affordable public housing schemes in Malaysia. The findings also offer guidelines to government officials and managers of public housing schemes to implement the IPHCM model that can help in reducing the financial burden on low- and middle-income households, improving maintenance work and enforcing effective management practices with residents’ participation.

Research limitations/implications
The paper is limited to develop a new Shariah-compliant affordable public housing model. The paper presents a design and defines the underlying Shariah concept and contracts and their working mechanisms in the proposed model. The paper has not considered other related areas in the development of IPHCM model including Shariah and subject matter expert’s perspective, consumer behavioural intention, legal and regulatory requirements.

Originality/value
The paper has relevance for policymakers and government institutions offering affordable public housing schemes to ensure successful deliverability of sustainable and affordable public housing for low- and middle-income households in Malaysia.
To stay or not to stay? Discontinuance intention of gamification apps
Authors: Huang Cheng-Kui , Chen Chun-Der , Liu Yu-Tzu 
Published: March 2019

Purpose
As the application of gamification is gaining great attention and has grown increasingly, thousands of these applications can be easily obtained from mobile phone stores, thus causing intensified competition and discontinuance of use accordingly. Besides, though understanding what factors influence the discontinuance of use of information systems (ISs) is critical for theoretical as well as practical reasons, studies pertaining to the saliency of the final phase, termination of an IS, are still limited. As such, the purpose of this paper is to propose a holistic view to fulfill the above-mentioned research gaps based on the expectation-confirmation model with other salient factors such regret, habit and gamification app values.

Design/methodology/approach
The context of a fitness gamification app is investigated. A total of 210 valid responses were received, and structural equation modeling was applied for data analysis.

Findings
The findings of this paper are as follows: among all factors influencing discontinuance intention, regret is the strongest, habit is second and gamification is third; among all factors affecting user satisfaction, gamification app value is the strongest, confirmation is second, perceived usefulness (PU) and perceived ease of use are third and regret is the last one; for factors influencing users’ habits, satisfaction is the strongest, following by PU and frequency of prior use; confirmation negatively influences the degree of regret; and confirmation positively influences PU.

Originality/value
This study highlights the important determinants influencing users’ discontinuance intentions in the context of gamification apps by incorporating two overlooked factors, regret and habit. Besides, this study suggests that app designers can not only increase user’s perceived value through external cooperation with other alternatives, but can be through internal enhancement with diverse services development as well.
Credit ratings and audit opinion: evidence from Tunisia
Authors: Moalla Hanen , Baili Rahma 
Published: March 2019

Purpose
The purpose of this paper is to examine whether credit ratings issued by Fitch predict auditor’s opinion for the Tunisian financial companies. It studies the association between Fitch’s credit rating and the audit opinion.

Design/methodology/approach
The whole population was analyzed. It is composed of 35 banks, leasing companies and factoring companies in Tunisia. The hand-collected data over 11 years (2005–2015) were used and a multiple-ordered logistic regression was performed.

Findings
The findings show that firms with a high short-term grade, a high long-term grade or a positive outlook are more likely to receive an unqualified audit opinion. In addition, companies with a stable outlook are more likely to receive an explanatory paragraph, a qualification or a going-concern opinion.

Originality/value
Studies examining the relationship between credit ratings and audit opinion are rare. This piece of research adds to knowledge about the relationship between different components of agency ratings and the auditor’s opinion in a developing country. Previous studies have investigated the case of developed countries and have been interested in the only impact of the long-term credit rating. This study analyzes three components of credit rating, namely long-term credit rating, short-term credit rating and rating outlook. In addition, it sheds light on the effect of various rating grades issued by rating agencies on the audit opinion. It gives a broader view of the relationship between credit ratings and audit opinion.
Reducing consumer loneliness through brand communities
Authors: Snyder Deirdre G. , Newman Kevin P. 
Published: March 2019

Purpose
The purpose of this paper is to examine the role of belonging to brand communities in improving consumer well-being and brand evaluations.

Design/methodology/approach
Two studies were conducted. Study 1 manipulates the framing of a brand to be either socially- or product-oriented and measures brand community joining intentions based on underlying levels of consumer loneliness and need to belong. Study 2 manipulates feelings of belongingness with a brand community and measures its impact on relatedness satisfaction, state loneliness and brand evaluations.

Findings
Study 1 finds that lonely consumers with a high need to belong are more likely to express intentions to join a brand community when it is socially-oriented. Study 2 finds that belonging to a brand community improves relatedness satisfaction which, in turn, reduces state loneliness and improves brand evaluations.

Practical implications
This research has significant implications for marketing practitioners who are looking to foster relationships among consumers in the form of brand communities, especially given the positive impact of these communities on consumer well-being. These findings suggest that marketers should create brand communities that foster a social (rather than product) focus to create a sense of belongingness with the brand and among its community members, and that doing so can improve relatedness satisfaction needs and reduce consumer loneliness.

Originality/value
This research contributes to the growing literature on consumer loneliness and is among the first to identify the positive psychological outcomes of socially-oriented brand communities on loneliness.
Triggers of positive eWOM: exploration with web analytics
Authors: Amed Sultan , Mukherjee Srabanti , Das Prasun , Datta Biplab 
Published: March 2019

Purpose
The purpose of this paper is to determine the triggers of positive electronic word of mouth (eWOM) using real-time Big Data obtained from online retail sites/dedicated review sites.

Design/methodology/approach
In this study, real-time Big Data has been used and analysed through support vector machine, to segregate positive and negative eWOM. Thereafter, using natural language processing algorithms, this study has classified the triggers of positive eWOM based on their relative importance across six product categories.

Findings
The most important triggers of positive eWOM (like product experience, product type, product characteristics) were similar across different product categories. The second-level antecedents of positive eWOM included the person(s) for whom the product is purchased, the price and the source of the product, packaging and eagerness in patronising a brand.

Practical implications
The findings of this study indicate that the marketers who are active in the digital forum should encourage and incentivise their satisfied consumers to disseminate positive eWOM. Consumers with special interest for any product type (mothers or doctors for baby food) may be incentivised to write positive eWOM about the product’s ingredients/characteristics. Companies can launch the sequels of existing television or online advertisements addressing “for whom the product is purchased”.

Originality/value
This study identified the triggers of the positive eWOM using real-time Big Data extracted from online purchase platforms. This study also contributes to the literature by identifying the levels of triggers that are most, more and moderately important to the customers for writing positive reviews online.
Overcoming over-identification
Authors: Vieira Valter Afonso , da Silva Juliano Domingues , Gabler Colin 
Published: March 2019

PurposeThe purpose of this paper is threefold: first, to determine the impact of interpersonal identification on sales performance; second, to uncover whether or not that relationship changes direction based on levels organizational prestige; and third, to test the antecedent of managerial support on salesperson interpersonal identification. Ultimately, the authors want to provide sales managers with tangible ways to nurture the self-concept of their sales force while optimizing sales performance.Design/methodology/approachThe authors test the hypotheses using a data set of 196 B2C retail salespeople in the shoe industry. Respondents answered a printed questionnaire, which was analyzed using multiple linear regression and response surface analysis.FindingsThe authors find that managerial support does positively influence interpersonal identification among salespeople which, in turn, increases sales performance. However, the relationship is curvilinear, becoming negative when over-identification occurs. This inverted U-shaped relationship is moderated by organizational prestige such that the negative influence is overcome by employees who have pride and confidence in their organization.Practical implicationsManagers should balance the level of support that they provide their employees. While this mentorship generally leads to positive results, too much can lead to over-identification, and consequently reduce sales performance. However, this negative effect can be overcome if the salesperson perceives his organization as prestigious. Therefore, a mix of guidance and autonomy may foster the strongest self-concept among the sales team and generate the most positive outcomes. Further, managers should monitor their employees’ perceptions of the company, communicating its strong reputation internally to generate organizational prestige.Originality/valueThe authors extend social identity theory in a sales context to provide a better understanding of how self-concept can be altered – for better or worse – by the sales manager. The authors also show the importance of communicating your company’s social value to employees. While over-identification in the manager–employee dyad can create a “tipping point” where sales performance begins to decrease, organizational prestige may be able to overcome this effect, demonstrating the power of prestige. Together, the authors present the importance of contextual and external influences on individual sales performance.
A review on nutritional profile of the food from enset
Authors: Fanta Solomon Workneh , Neela Satheesh 
Published: March 2019

Purpose
This paper is a systemic review on enset plant’s role in Ethiopian people’s life as the source of food. This paper aims to summarize the traditional processing and preparation methods of enset-based foods and their nutritional composition.

Design/methodology/approach
Available scientific articles were collected and reviewed for enset plant evaluation, description, enset plant’s role in Ethiopian people’s food security, post harvesting and traditional processing of enset plants, microbiology of the fermented enset foods, different foods reported from enset, nutritional profile of the three food from enset base (kocho, bulla and amicho) and other non-food applications of enset plant.

Findings
Enset plant has a predominant role in people living in the southern part of Ethiopia. This plant is drought-tolerant and provides many non-food applications. Harvesting of the enset plant, preparing for fermentation and food preparations follow the traditional route by using the indigenous knowledge and practices. Limited studies have been reported on the microbiology of the enset fermentation, but various types of microbes have been reported. In case of nutritional composition, foods from enset are reported to contain high carbohydrate and minerals content, such as calcium, potassium and zinc, but limited protein content; they are also the best source of the essential amino acids such as lysine and leucine. Limited data are available on vitamins, anti-oxidant and fatty acids profiles of enset-based foods. The existing data indicate variations, and the reasons for variability are discussed in this paper.

Originality/value
Scientific reviews on enset food nutrition profile and related issues are scarce; this paper will compile information about enset plant-based foods for researchers for their future research.

Abstract

Despite great interest in metrics to quantify the structure of ecological networks, the effects of sampling and scale remain poorly understood. In fact, one of the most challenging issues in ecology is how to define suitable scales (i.e., temporal or spatial) to accurately describe and understand ecological systems.

Here, we sampled a series of ant–plant interaction networks in the southern Brazilian Amazon rainforest in order to determine whether the spatial sampling scale, from local to regional, affects our understanding of the structure of these networks.

To this end, we recorded ant–plant interactions in adjacent 25 × 30 m subplots (local sampling scale) nested within twelve 250 × 30 m plots (regional sampling scale). Moreover, we combined adjacent or random subplots and plots in order to increase the spatial sampling scales at the local and regional levels. We then calculated commonly used binary and quantitative network‐level metrics for both sampling scales (i.e., number of species and interactions, nestedness, specialization and modularity), all of which encompass a wide array of structural patterns in interaction networks.

We observed increasing species and interactions across sampling scales, and while most network descriptors remained relatively constant at the local level, there was more variation at the regional scale. Among all metrics, specialization was most constant across different spatial sampling scales. Furthermore, we observed that adjacent assembly did not generate more variation in network descriptor values compared to random assembly. This finding indicates that the spatially aggregated distribution of species/individuals and abiotic conditions does not affect the organization of these interacting assemblages.

Our results have a direct impact on our empirical and theoretical understanding of the ecological dynamics of species interactions by demonstrating that small spatial sampling scales should suffice to record some patterns commonly found in ant–plant interaction networks in a highly diverse tropical rainforest.
Lignin catabolic pathways reveal unique characteristics of dye‐decolorizing peroxidases in Pseudomonas putida
Authors: Lin Lu , Wang Xiaopeng , Cao Lanfang , Xu Meiying 
Published: March 2019

SummaryLignin is one of the largest carbon reservoirs in the environment, playing an important role in the global carbon cycle. However, lignin degradation in bacteria, especially non‐model organisms, has not been well characterized either enzymatically or genetically. Here, a lignin‐degrading bacterial strain, Pseudomonas putida A514, was used as the research model. Genomic and proteomic analyses suggested that two B subfamily dye‐decolorizing peroxidases (DypBs) were prominent in lignin depolymerization, while the classic O2‐dependent ring cleavage strategy was utilized in central pathways to catabolize lignin‐derived aromatic compounds that were funnelled by peripheral pathways. These enzymes, together with a range of transporters, sequential and expression‐dose dependent regulation and stress response systems coordinated for lignin metabolism. Catalytic assays indicated these DypBs show unique Mn2+ independent lignin depolymerization activity, while Mn2+ oxidation activity is absent. Furthermore, a high synergy between DypB enzymes and A514 cells was observed to promote cell growth (5 × 1012 cfus/ml) and lignin degradation (27%). This suggested DypBs are competitive lignin biocatalysts and pinpointed limited extracellular secretion capacity as the rate‐limiting factor in bacterial lignin degradation. DypB production was, therefore, optimized in recombinant strains and a 14,141‐fold increase in DypB activity (56,565 U/l) was achieved, providing novel insights for lignin bioconversion.

AbstractObjectivesTo report on the safety and efficacy of transvenous cardiac pacing wire insertion outside a tertiary hospital by a medical retrieval service.MethodsSAAS MedSTAR Emergency Medical Retrieval Service transports symptomatic bradycardic patients in rural South Australia to Adelaide on transvenous pacing for ongoing management. This is a retrospective case review of all transvenous cardiac pacing wires inserted by SAAS MedSTAR between January 2015 and October 2017.ResultsThis study demonstrated successful insertion of cardiac transvenous pacing wires and cardiac capture in 10 of 11 cases (91%) by pre‐hospital and retrieval doctors. There were no immediate or long‐term complications from insertion. All of the patients were successfully transferred by helicopter or fixed wing to their receiving facility, with nine of the 11 patients (82%) surviving to hospital discharge.ConclusionThis paper demonstrates that transvenous cardiac pacing can be safely and successfully implemented for symptomatic patients by pre‐hospital and retrieval physicians in the aeromedical retrieval setting.
Biochemistry, genetics and biotechnology of glycerol utilization in Pseudomonas species
Authors: Poblete‐Castro Ignacio , Wittmann Christoph , Nikel Pablo I. 
Published: March 2019

SummaryThe use of renewable waste feedstocks is an environment‐friendly choice contributing to the reduction of waste treatment costs and increasing the economic value of industrial by‐products. Glycerol (1,2,3‐propanetriol), a simple polyol compound widely distributed in biological systems, constitutes a prime example of a relatively cheap and readily available substrate to be used in bioprocesses. Extensively exploited as an ingredient in the food and pharmaceutical industries, glycerol is also the main by‐product of biodiesel production, which has resulted in a progressive drop in substrate price over the years. Consequently, glycerol has become an attractive substrate in biotechnology, and several chemical commodities currently produced from petroleum have been shown to be obtained from this polyol using whole‐cell biocatalysts with both wild‐type and engineered bacterial strains. Pseudomonas species, endowed with a versatile and rich metabolism, have been adopted for the conversion of glycerol into value‐added products (ranging from simple molecules to structurally complex biopolymers, e.g. polyhydroxyalkanoates), and a number of metabolic engineering strategies have been deployed to increase the number of applications of glycerol as a cost‐effective substrate. The unique genetic and metabolic features of glycerol‐grown Pseudomonas are presented in this review, along with relevant examples of bioprocesses based on this substrate – and the synthetic biology and metabolic engineering strategies implemented in bacteria of this genus aimed at glycerol valorization.
Occurrence and diversity of the oxidative hydroxyhydroquinone pathway for the anaerobic degradation of aromatic compounds in nitrate‐reducing bacteria
Authors: Pacheco‐Sánchez Daniel , Rama‐Garda Ramón , Marín Patricia , Martirani‐Von Abercron Sophie‐Marie , Marqués Silvia 
Published: March 2019

AbstractThe nitrate‐reducing betaproteobacteria Azoarcus anaerobius and Thauera aromatica AR‐1 use an oxidative mechanism to anaerobically degrade resorcinol and 3,5‐dihydroxybenzoate (3,5‐DHB), respectively, rendering hydroxyhydroquinone as intermediate. The first pathway step is performed by a dimethylsulphoxide‐reductase family hydroxylase. The gene cluster coding for the pathway is homologous in these strains. Only these two Rhodocyclales are known to follow this anaerobic pathway, and nothing is known about its distribution in prokaryotes. To determine the relevance and diversity of this strategy in nature, we enriched for bacteria able to oxidize resorcinol or 3,5‐DHB under denitrifying conditions. Nitrate‐reducing bacteria able to degrade these compounds were present in soil, aquifer and marine sediments. We were able to isolate a number of strains with this capacity from soil and aquifer samples. Amplicon libraries of rehL, the gene encoding the first step of this pathway, showed an overall low diversity, most sequences clustering with either pathway enzyme. Isolates belonging to the Beta‐ and Gammaproteobacteria able to grow on these substrates revealed rehL homologues only in strains belonging to Thauera and Azoarcus. Analysis of sequenced genomes in the databases detected the presence of highly similar clusters in two additional betaproteobacteria and in the gammaproteobacterium Sedimenticola selenatireducens, although anaerobic growth on a dihydroxyaromatic could only be confirmed in Thauera chlorobenzoica 3CB‐1. The presence of mobile elements in the flanking sequences of some of the clusters suggested events of horizontal gene transfer, probably contributing to expand the pathway to a broader host range within the Proteobacteria.
