Abstract

Purpose

Solid waste (SW) is the result of rapid urbanization and industrialization, and is increasing day by day by the increasing number of population. This thesis paper emphasizes on the prediction of SW generation in the city of Dhaka and finding sustainable pathways for minimizing the gaps in the existing system.

Design/methodology/approach

In this paper, the survey of different questionnaires of the Dhaka South City Corporation (DSCC) was conducted. The data of SW generation, for few years of each month, in the city of Dhaka were collected to develop a model named Artificial Neural Network (ANN). The ANN model was used for the accurate prediction of SW generation.

Findings

At first, by using the ANN model with the one hidden layer and changing the number of neurons of the layer different models were created and tested. Finally, according to R values (training, test, all) the structure with six neurons in the hidden layer was selected as the suitable model. Finally, six gaps were found in the existing system of solid waste management (SWM) in the DSCC. These gaps are the main barrier for the better SWM.

Originality/value

The authors propose that the best model for prediction is 12-6-3, and its training and testing results are given as 0.9972 and 0.80380, respectively. So the resulting prediction is so much close in comparison with actual data. In this paper, the opportunities of those gaps are provided for working properly and the DSCC will find the better result in the aspect of SW problem.

Abstract

Purpose

Shape memory polymers (SMPs) respond with a change in their shape against a specific stimulus by memorizing their original shape and are reformed after deformation most often by changing the temperature of the surrounding without additional mechanical efforts. In the coming years, these polymers indeed will be in limelight to manufacture textile materials which will retain their shape even after prolonged use under disturbed conditions. This study aims at defining shape memory materials and polymers as well as their technological characteristics and also highlights application in various fields of textiles.

Design/methodology/approach

The methodology used to explain these SMPs have been carried out starting with the discussion on their properties, their physical nature, types, viz., shape memory alloys (SMAs), shape memory ceramics, shape memory hybrid, magnetic shape memory alloy, shape memory composites, shape memory gels and SMP along with properties of each type. Other related details of these polymers, such as their advantages, structure and mechanism, shape memory functionality, thermally responsive SMPs and applications, have been detailed.

Findings

It has been observed that the SMPs are very important in the fields of wet and melt-spun fibers to offer novel and functional properties, cotton and wool fabric finishing, to produce SMP films, foams and laminated textiles, water vapor permeable and breathable SMP films, etc.

Originality/value

The field of SMPs is new, and very limited information is available to enable their smooth production and handling.

Abstract

The change in Malaysian financial environment can be attributed to digitalization as banks are racing to digital maturity by 2020. Historically in Malaysia, the use of credit card was a Fintech development in the 1950s to help Malaysians minimize the burden in carrying cash all the time. The aim of financial technology in the 1990s was to encourage bank customers to use the online banking system instead of only automated teller machine. Fintech services are swiftly interrupting banks' services globally. Similarly, Malaysia's banking sector is experiencing the interruption since as more Fintech organizations are innovating new Fintech service to improve convenience for clienteles. Numerous regulatory agencies in Malaysia and the Malaysian government have set up several initiatives to encourage and provide a vigorous growth in the Malaysian Fintech and digital asset regulatory environment. Expectation Confirmation Model, Technology Acceptance Model, and Cognitive Model are viewed as the most popular frameworks that discuss the continuous intention to use information system. The combination of these three models has led to the creation of Technology Continuance Theory (TCT). TCT postulates that five prominent constructs or antecedents are depicted as key indicators in explaining the users' intentions for continuous use: (1) confirmation, (2) perceived usefulness, (3) perceived ease of use, (4) satisfaction, and (5) attitude. Furthermore, TCT adds to the argument on the consumers' continuance adoptions by assimilating satisfaction and attitude into a single construct.

Abstract

Purpose

This study aims to theoretically explore and examine the possibility of developing an Islamic social welfare function (ISWF) within the Islamic moral economy (IME) frame by going beyond the traditional fiqhī approach. It focuses on issues of preference ordering and utility through the normative dimension of Islamic ontology, as expressed and articulated within the IME.

Design/methodology/approach

Being a theoretical paper, a conceptual and critical discursive approach is used in this paper.

Findings

To establish an ISWF, a narrow juristic approach remains inadequate; there is a need to integrate the substantive morality to complement the juristic approach to achieve the ihsani process as the ultimate individual objective, which makes an ISWF possible. As the scattered debate on the topic concentrates mainly on the juristic approach, the main contribution of this study is to present a model in which juristic and moralist positions endogenized and augmented to constitute ISWF.

Originality/value

As there is a limited amount of research available on the subject matter, this paper will be an important theoretical contribution. In addition, this study develops an IME approach rather than fiqh-based approach used in the available research, which makes it novel.

Abstract

Purpose

The purpose of this paper is to identify social entrepreneurship dimensions that emphasize the specific personal characteristics of social entrepreneurs (SPCSE) and social entrepreneurship organization (SEO) among students in higher education institutions who are active participants of the Students in Free Enterprise (SIFE) program in Malaysia.

Design/methodology/approach

Quantitative approaches and instruments were used to analyze the profile of social entrepreneurship in this cross-sectional survey study, which involved 394 active SIFE students in Malaysia in 2011. The Statistical Package for Social Sciences (SPSS) was used to analyze the data and describe the SIFE student's SPCSE and SEO.

Findings

The social entrepreneurship of the SIFE students was high, with a dominant SEO. However, the dimensions of SPCSE need to be applied effectively to the students involved, whose social entrepreneurship was merely moderate. There was a strong positive relationship between SPCSE and SEO of SIFE students, with a Pearson correlation coefficient of 0.73.

Research limitations/implications

It is recommended that further longitudinal research be conducted to assess the depth of the impact of social entrepreneurship on SIFE students. In this manner, more useful information related to the impact can be leveraged to improve the pattern of the social entrepreneurship program.

Practical implications

The SIFE participants’ social entrepreneurship profile can be used by the Ministry of Higher Education in formulating social entrepreneurship policy for higher education institutions. The Malaysia SIFE Foundation and the administrators of higher education institutions should encourage more university students to participate in SIFE program to increase the number of social entrepreneurs who will help solve social, economic, and environmental problems.

Originality/value

There has been no discussions of the social entrepreneurship programs in Malaysia. This paper attempts to fill the current gap.

Abstract

Purpose

This study aims to investigate the effects of incorporating seaweed composite flour on soft roll dough rheological characteristics and quality.

Design/methodology/approach

In this study, wheat flour was substituted with seaweed powder obtained from red seaweed (Kappaphycus alvarezii) at varying proportions (100:0; 99:1; 98:2; 97:3; 96:4; 95:5, 94:6, 93:7 and 92:8) and applied in soft roll production. The effects of seaweed composite flour were evaluated in terms of rheological characteristics, proximate composition and physical properties. The sensory characteristics of the soft rolls was evaluated by 40 untrained panellists by using a hedonic scale.

Findings

Farinograph analysis of the soft roll doughs showed that the incorporation of seaweed powder promoted an increase in water absorption, development time and mixing tolerance index, whereas it decreased stability time. Analysis of the proximate composition of the soft rolls showed that protein and carbohydrate contents decreased, but moisture, ash and crude fibre contents substantially increased. Dietary fibre increased with the increase in the proportion of seaweed powder added. The specific volume, bulk density and firmness of the soft rolls ranged from 3.01 to 5.48 cm3/g, 0.18 to 0.33 g/cm3 and 1.86 to 20.63 N, respectively. Sensory evaluation results showed that the mean score of sensory attributes decreased as the proportion of seaweed powder added was increased in the formulations. With regard to the overall acceptability, the panellists preferred the soft rolls with the least amount of seaweed powder added. The results of hedonic tests revealed that the panellists' acceptance decreased as higher amounts seaweed powder were added in the formulations.

Originality/value

This study showed that the seaweed powder of K. alvarezii can be utilised as an ingredient to improve the nutrient composition of baked products.

Abstract

Purpose

The purpose of this paper is to investigate service quality, patient satisfaction and loyalty in Bangladesh’s healthcare sector. It identifies healthcare quality conformance, patient satisfaction and loyalty based on demographics such as gender, age and marital status. It examines the differences between public and private healthcare sectors regarding service quality, patient satisfaction and loyalty.

Design/methodology/approach

The authors distributed 450 self-administered questionnaires to hospital patients resulting in 204 useful responses (45.3 per cent response rate). Data were analysed based on reliability analysis, exploratory factor analysis, independent samples t-tests, ANOVA and discriminant analysis using SPSS version 23.

Findings

Findings indicate that single patients perceive tangibles, reliability, empathy and loyalty higher compared to married patients. Young patients (⩽20 years) have a higher tangibles, empathy and loyalty scores compared to other age groups. The authors observed that private hospital patients perceive healthcare service quality performance higher compared to patients in public hospitals.

Research limitations/implications

The authors focussed solely on the Bangladesh health sector, so the results might not be applicable to other countries.

Originality/value

The findings provide guidelines for enhancing service quality, patient satisfaction and loyalty in the Bangladesh healthcare sector and other countries.

Abstract

Purpose

This empirical analysis tries to examine determinants of private foreign direct investment (FDI) in Pakistan using the bounds test approach. Main determinants of FDI among them are the size of the market (Q) macroeconomic stability (r), political stability (PRS), real exchange rate (REX) and institutional quality (INQ).

Design/methodology/approach

This study used annual time-series data set starting from 1980 to 2016. This study has used time-series data with ARDL and error-correction model (ECM) and examined main determinants of FDI for Pakistan. The study used the Granger causality test (modified WALD test) to identify the causality among the variables.

Findings

Moreover, empirical findings indicate the long-run relationship between GDP, trade openness and institutional quality toward FDI. However, political instability, inflation and real exchange rate harm FDI in Pakistan. Furthermore, results of Granger causality indicate that the bidirectional causality running from FDI and Q toward FDI is significant, providing evidence of FDI-led growth hypotheses in Pakistan. This study determines the correlation between FDI and Q (GDP growth) related to the “feedback hypothesis” in the short and long run. This study also concludes that the short-run causal connection among FDI, REX, PRS, r and Q follows the “feedback hypothesis.” This describes that FDI, REX, PRS, r and Q variables are jointly determined and affected together.

Originality/value

This study also explores the causal association between FDI and its significant determinants, by using methods of Granger causality test and the approach of Toda-Yamamoto-DoladoLutkephol (TYDL) to examine the causal relationship and its directions among these variables.

Abstract

Purpose

The most commonly used approaches for cluster validation are based on indices but the majority of the existing cluster validity indices do not work well on data sets of different complexities. The purpose of this paper is to propose a new cluster validity index (ARSD index) that works well on all types of data sets.

Design/methodology/approach

The authors introduce a new compactness measure that depicts the typical behaviour of a cluster where more points are located around the centre and lesser points towards the outer edge of the cluster. A novel penalty function is proposed for determining the distinctness measure of clusters. Random linear search-algorithm is employed to evaluate and compare the performance of the five commonly known validity indices and the proposed validity index. The values of the six indices are computed for all nc ranging from (nc min, nc max) to obtain the optimal number of clusters present in a data set. The data sets used in the experiments include shaped, Gaussian-like and real data sets.

Findings

Through extensive experimental study, it is observed that the proposed validity index is found to be more consistent and reliable in indicating the correct number of clusters compared to other validity indices. This is experimentally demonstrated on 11 data sets where the proposed index has achieved better results.

Originality/value

The originality of the research paper includes proposing a novel cluster validity index which is used to determine the optimal number of clusters present in data sets of different complexities.

Abstract

Purpose

This paper aims to explore the potential of the awareness and knowledge of Islamic social finance (zakat, waqf and Islamic microfinance) to alleviate poverty during the COVID-19 pandemic with the moderating effect of ethical orientation.

Design/methodology/approach

The data were collected through the administration of paper-based and electronic questionnaires to 400 respondents out of which only 277 were found valid for analysis.

Findings

The study showed that by direct relationship, the awareness and knowledge of Islamic social finance instruments have a potentially significant positive contribution to poverty alleviation during the COVID-19 pandemic except for zakat that has an insignificant positive contribution. Ethical oriental has also a significant positive contribution. Contrary to expectation, the moderating effect of ethical orientation has changed zakat and waqf to have significant negative and insignificant positive contributions, respectively. Only Islamic microfinance has endured the moderating effect to continue contributing significantly and positively to the reduction of poverty.

Research limitations/implications

The study explored only the potential impact of the awareness and knowledge of Islamic social finance to mitigate the extreme poverty caused by the COVID-19 pandemic in Nigeria.

Practical implications

This study clearly showed the need to create enabling laws and policies to support the operations of zakat and waqf institutions to achieve their objectives effectively and efficiently. These two institutions should be integrated with Islamic microfinance for the possibility of getting better outcomes.

Social implications

There should be massive campaigns to restore religious, social and political ethics to enhance the socio-economic development of Nigerians based on the principles of brotherhood.

Originality/value

This study provides unexpected and unusual results showing the inability of zakat and waqf institutions to alleviate poverty due to poor ethical orientation.
