Abstract
Purpose
This study aims to comprehensively address the challenge of delineating traffic scenarios in video footage captured by an embedded camera within an autonomous vehicle.
Design/methodology/approach
This methodology involves systematically elucidating the traffic context by leveraging data from the object recognition subsystem embedded in vehicular road infrastructure. A knowledge base containing production rules and logical inference mechanism was developed. These components enable real-time procedures for describing traffic situations.
Findings
The production rule system focuses on semantically modeling entities that are categorized as traffic lights and road signs. The effectiveness of the methodology was tested experimentally using diverse image datasets representing various meteorological conditions. A thorough analysis of the results was conducted, which opens avenues for future research.
Originality/value
Originality lies in the potential integration of the developed methodology into an autonomous vehicle’s control system, working alongside other procedures that analyze the current situation. These applications extend to driver assistance systems, harmonized with augmented reality technology, and enhance human decision-making processes.

Abstract
Purpose
The purpose of this paper is to know how do early-phase planning of real estate (RE) and facilities management (FM) create value for owners and users of commercial and public sector buildings.
Design/methodology/approach
The data were collected in Norway in 2015 through a national online survey (N = 837). The sample gives a good picture of Norwegian owners’ and even users on tactical-level (customer) perspectives on RE and FM. The data have been analysed through descriptive statistics and exploratory factor analysis. The hypotheses have been tested through analyses of correlations and ordinary least square (OLS) linear regressions.
Findings
Exploratory factor analysis made it possible to establish seven composite variables (constructs). Based on these seven constructs, six hypotheses were derived and tested. Obstacles and financials have no significant effect on buildings’ perceived usability. The most important factors during early-phase planning that influence buildings’ perceived usability and lifetime value creation are measures promoting environment and life-cycle costs (LCC), FM, adaptability and image.
Research limitations/implications
Further empirical and preferably, comparative studies are needed to establish whether the findings can be generalized. The study has shown that a building’s usability and lifetime value creation is largely determined by decisions made during early phase planning.
Practical implications
Well-founded early-phase planning of RE and FM may actually provide very high return on the investments and significantly improve the buildings’ lifetime value creation for owners and users. Early-phase planning is also of great importance both for buildings’ physical design, as well as for successful FM during the buildings’ use phase, and may prevent irreversible blunders.
Originality/value
This is a large N empirical study in Norway. The findings indicate what owner and users of buildings should emphasize during early phase planning.

Abstract
Purpose
Health promotion and disease prevention by means of functional foods have become more popular among consumers due to the rising trend of non-communicable diseases. Driven by the increased demand, the authors aimed to investigate sensorial, nutritional and physicochemical properties of chicken nugget incorporated with unripe Cavendish banana and Flavourzyme® [Control (without banana and Flavourzyme®), F1 (banana only), F2 (Flavourzyme® only), F3 (banana and Flavourzyme®)].
Design/methodology/approach
Sensory evaluation was carried out by means of 9-point hedonic scale among consumer panels (n = 83) to evaluate control, F1, F2 and F3. These were then subjected to chemical (moisture, protein, fat, ash, carbohydrate, total dietary fibre, potassium and antioxidant contents) and physical (texture profile and water activity) analyses.
Findings
Sensory acceptance of control was significantly higher compared to other formulations. Fibre, antioxidant and potassium contents were significantly higher, although moisture, protein and fat contents were significantly lower in F1 and F3 compared to control. Remarkably, F1 and F3 were eligible to be declared as “source of dietary fibre”. Therefore, F1, F2 and F3 can serve as healthier alternatives with high antioxidant activity without compromising consumers' acceptance.
Originality/value
This innovative study generates unique findings pertaining to the nutritional values of novel functional chicken nugget and the formulation enables it to be declared as a source of dietary fibre. Results have contributed knowledge to existing literature as well as benefits food manufacturers in creating healthy functional food to better meet the needs and expectations of health-conscious consumers, healthcare providers, governmental organisations and consumer advocacy groups.

Abstract
Purpose
The Gulf Cooperation Council member countries not only generate the highest quantity of municipal solid waste (MSW) per capita when compared globally, but also in most of these countries, such waste is just dumped at different landfill stations. In Oman, the total quantity of MSW stood at 2.0 million tons per year. The emission from this waste is estimated at 2,181,034 tons/year (carbon dioxide equivalent). This article attempts to develop frameworks that considered landfilling, composting and recycling of MSW.
Design/methodology/approach
To know the composition of the municipal solid waste in Oman, a quantitative research method was employed. The greenhouse gas (GHG) emissions from MSWM in this study focus on three major gases, CO2, CH4 and N2O. The Intergovernmental Panel on Climate Change (IPCC) 2006 model is used to calculate GHG emissions from landfills and composting (IPCC, 2006). Four frameworks – baseline F0, framework F1, framework F2 and framework F3 – are outlined in this paper. The F0 represents the current situation of the MSW in which most of the waste goes to landfills and dumpsites. In F1, improved MSW collection service and landfilling are incorporated and open burning is restricted. The F2 considered landfilling and composting, while F3 is based on landfilling, composting and recycling.
Findings
The framework F2, which proposes the composting process for the organic waste which normally goes to landfills, results in the reduction of emissions by 40% as compared to landfill practice. Similarly, the samples of MSW collected in Oman show a good amount of recycling waste. The framework F3, which considers the landfill, composting and recycling, reduced the total GHG emissions from 2,181,034 tons/year to 1,427,998 tons/year (carbon dioxide equivalent), representing a total reduction of 35% in emissions.
Research limitations/implications
Different values such as CH4 correction factor, the fraction of degradable organic carbon and the fraction of DOC used to determine the GHG emissions from MSW considering landfilling, composting and recycling based on the IPPC model and existing literature review. The actual determination of these values based on the Oman conditions may result in more accurate emissions from MSW in Oman.
Practical implications
Different frameworks suggested in this research have different practical implications; however, the final framework F3, which produces fewer emissions, required a material recovery facility to recycle the MSW in Oman. For framework F3, it is important that the residents in Oman have enough knowledge and willingness to do the waste segregation at the household level. Apparently, such knowledge and willingness need to be determined through a separate study.
Originality/value
The frameworks F2 and F3 are considered to be more suitable solutions compared to the current practices for Oman and other gulf countries to reduce its per capita emissions from MSW and protect its local environment. There is a potential for further work that needs to explore the possible solutions to implement the suggested frameworks.

Abstract
Purpose
In recent years, global demand for functional foods grew tremendously due to the rising trend of health-conscious consumers. Driven by increased awareness of probiotic products, consumption of yogurt drink is gaining popularity across all age groups. In the present study, the authors aimed to assess sensorial, nutritional and technological properties of synbiotic yogurt drink enriched with prebiotic inulin.
Design/methodology/approach
Sensory analysis, proximate compositions, viscosity, viable count and DPPH radical scavenging activity were examined in control (without inulin) and 3 variants of inulin-supplemented synbiotic yogurt drink, namely F1 (4%, inulin), F2 (4.5% inulin) and F3 (5% inulin).
Findings
Evaluated by 75 consumer panellists on 9-point hedonic scales, F3 showed significantly (p < 0.05) higher overall acceptability (5.79 ± 1.94) compared to control. In addition to lower calorie content (36.52 kcal/100 ml), nutritional and technological properties of F3 [total dietary fibre content (4.03 ± 0.04 g/100 ml), viscosity (28 ± 6.93 cP), viable count (87.00 ± 4.00 × 106 CFU/ml S. thermophilus; 14.67 ± 3.51 × 106 CFU/ml L. bulgaricus) and antioxidant activity (50.40 ± 1.80%)] were significantly (p < 0.05) improved compared to control. Remarkably, the new formulation complied with nutrient criteria for Healthier Choice Logo Malaysia in addition to meeting requirements for “low fat” and “high dietary fibre” contents according to Malaysia Guide to Nutrition Labelling and Claims. Hence, we conclude that 5% inulin improved nutritional and technological characteristic in synbiotic yogurt drink without compromising consumers' acceptance.
Originality/value
This novel study showcases the incorporation of prebiotic inulin in the development of synbiotic yogurt drink. Remarkably, this new formulation complied with the nutrient criteria for Healthier Choice Logo Malaysia in addition to meeting the requirements for “low fat” and “high dietary fibre” contents according to Malaysia Guide to Nutrition Labelling and Claims. More importantly, results have contributed knowledge to existing literature as well as benefits food manufacturers in creating healthy yogurt drinks to better meet the needs and expectations of health-conscious consumers without compromising hedonic perceptions.

Abstract
Purpose
The purpose of this study is to identify organisational homeostasis factors in the context of healthcare organisations and to develop a conceptual model for green transformation.
Design/methodology/approach
The organisational homeostasis factors were determined by review of literature study and the opinions of healthcare experts. Scheduled interviews and closed-ended questionnaires are employed to collect data for this research. This study employed “TISM methodology” and “MICMAC analysis” to better comprehend how the components interact with one another and prioritise them based on their driving and dependence power.
Findings
This study identified 10 factors of organisational homeostasis in healthcare organisation. Recognition of interdependence, hormesis, strategic coalignment, consciousness on dependence of healthcare resources and cybernetic principle of regulations are the driving or key factors of this study.
Research limitations/implications
The study's primary focus was on the organisational homeostasis factors in healthcare organisations. The methodological approach and structural model are used in a healthcare organisation; in the future, these approaches can be applied to other industries as well.
Practical implications
The key drivers of organisational homeostasis and the identified factors will be better comprehended and understood by academic and important stakeholders in healthcare organisations. Prioritizing the factors helps the policymakers to comprehend the organisational homeostasis for green transformation in healthcare.
Originality/value
In this study, the TISM and MICMAC analysis for healthcare is proposed as an innovative approach to address the organisational homeostasis concept in the context of green transformation in healthcare organisations.

Abstract
We investigate producers’ choice between geographical indications (GI) and brand advertising (BA) as pure marketing strategies to convey information to consumers. Producers also decide whether or not to select an effort level for improving the quality of their products. We identify conditions under which GI and BA emerge with and without quality effort, depending on the relative costs and effectiveness of marketing strategies and quality improvement. Beyond the conventional equilibrium cases of GI-no-quality-effort and BA-with-quality-effort, we identify several other equilibrium strategies. Under plausible parameter characterization, and in spite of the free-riding problem of collective reputation, producers choose GI and quality improvement efforts at equilibrium. This occurs when the cost of marketing is high, the relative cost of quality effort is low relative to the former, and when the effectiveness of marketing promotions is low. BA without quality improvement also emerges as an equilibrium strategy for the opposite cost structure (low cost of promotion, high cost of effort relative to promotion, and higher effectiveness of promotion). Finally, the joint selection of both instruments BA and GI is examined. We motivate and illustrate our analysis with the European and New-World wine industries.
