Abstract

Purpose

This study was intended to ensure learner-centred pedagogy in an open and distance learning environment by applying scaffolding and positive reinforcement techniques.

Design/methodology/approach

This study critically analysed the context and current instructional practice of Bangladesh Open University (BOU) via document analysis and literature review. The conceptual framework of this study was adapted from the ADDIE model, i.e. the analysis, design, development, implementation and evaluation model.

Findings

The study explored that the instructional practice of BOU was dominated by teacher-centred pedagogy. Hence, to ensure learner-centred pedagogy, the researchers developed three model lesson plans. These lesson plans infused the theoretical directives of scaffolding and positive reinforcement as well as several assessment tasks which can assess the learners’ lower-order and higher-order thinking skills. The researchers also presented possible challenges for the sound implementation of these model lesson plans and suggested pragmatic solutions accordingly.

Originality/value

This study recommended that the combined application of scaffolding and positive reinforcement would effectively ensure learner-centred pedagogy.

Abstract

Purpose

Speech disorder is one of the most common problems found with autistic children. The purpose of this paper is to investigate the introduction of computer‐based interactive games along with the traditional therapies in order to help improve the speech of autistic children.

Design/methodology/approach

From analysis of the works of Ivar Lovaas, it is already known that there are several disadvantages to the “applied behavior analysis” approach to solve the problems of autistic children; so the authors' methodologies were to encourage children with Autism Spectrum Disorders (ASD) to “play,” where playing is mediated through technology. By creating technological methods of interaction (visual displays and physical robots), play and comfortable interactions can be garnered from children with autism. There is a feeling of “safety” in having the main form of interaction occur with non‐humans. Further, these devices allow the child, rather than a third party, to be in control of the interactions.

Findings

From the observations, it could found that the problems of autistic children have a wide range and it is almost impossible to design a single game for a group of children. Instead, each child needs to be treated individually. Hence, the authors are suggesting different types of games for different problems.

Research limitations/implications

The authors have proposed some computer game‐based therapies for two types of autism that are discussed in the paper. Interactive games can be built for other types too. After having a group of these games it can be an experimental topic to determine the order of execution of these therapies. However, the proposed games heavily depend on the instructors. Research should be conducted to minimize the duties of instructor.

Social implications

The autism spectral disorders are defined by the qualitative impairments in social communication. Although the actual reason for autism is still unknown to the medical sciences, it has been proved to be the result of abnormal and irregular growth of cerebral neurons of human brains. People suffering from autism very often demonstrate a poor performance in social interactions and hence find it difficult to communicate with other people. So if vocalization can be encouraged at the age of 3, a pivotal age for children with ASD, this could lead to an increased communicative ability, which makes not only the child's life easier, but also increases their chances of functioning in the world around them.

Originality/value

This paper offers a hierarchy of speaking skills and suggests corresponding games for each stage to achieve a necessary level of efficiency.

Abstract

Purpose

This paper explores the reasons behind the slow uptake of mobile payment (m-payment) from a switching intention (SI) perspective. The antecedents of SI from cash to m-payment were explored using an integrated conceptual model of the push-pull-mooring (PPM) framework and the status quo bias (SQB) perspective.

Design/methodology/approach

A self-administered survey was used to collect data, which are empirically tested using SmartPLS 3.0.

Findings

The push factor was found to have an insignificant effect on SI to m-payment whereas the pull factor was significant. Furthermore, the results revealed that the two mooring variables have contrasting results as trust is not a significant determinant of SI to m-payment while perceived security and privacy (PSP) is. Additionally, all SQB-related relationships were found to be statistically significant

Originality/value

This study determined the factors that play vital roles in the consumers' decision-making to transition from cash to m-payment. This was done via a uniquely developed conceptual model that incorporated the PPM framework with the SQB perspective.

Abstract

Purpose

This work encompasses the various laboratory-based and portable methods evolved in recent times for sensitive and selective detection of ethylene for fruit-ripening application. The role of ethylene in natural and artificial fruit ripening and the associated health hazards are well known. So there is a growing need for ethylene detection. This paper aims to highlight potential methods developed for ethylene detection by various researchers, including ours. Intense efforts by various researchers have been on since 2014 for societal benefits.

Design/methodology/approach

The paper focuses on types of sensors, fabrication methods and signal conditioning circuits for ethylene detection in ppm levels for various applications. The authors have already designed, developed a laboratory-based set-up belonging to the electrochemical and optical methods for detection of ethylene.

Findings

The authors have developed a carbon nanotube (CNT)-based chemical sensor whose performance is higher than the reported sensor in terms of material, sensitivity and response, the sensor element being multi-walled carbon nanotube (MWCNT) in comparison to single-walled carbon nanotube (SWCNT). Also the authors have developed infrared (IR)-based physical sensor for the first time based on the strong IR absorption of ethylene at 10.6 µm. These methods have been compared with literature based on comparable parameters. The review highlights the potential possibilities for development of portable device for field applications.

Originality/value

The authors have reported new chemical and physical sensors for ethylene detection and quantification. It is demonstrated that it could be used for fruit-ripening applications A comparison of reported methods and potential opportunities is discussed.

Abstract

Purpose

This paper focuses on the factors that affect entrepreneurs' performance in small and medium enterprises (SMEs) in the context of a developing nation. Despite the advances in this literature, examination of opportunity recognition in the same model with personal factors and environmental factors on entrepreneurs' performance is lacking.

Design/methodology/approach

A quantitative survey was carried out and the data sample of 198 SMEs entrepreneurs in Bangladesh was collected using quota sampling technique. Partial least squares-based structural equation modeling (PLS-SEM) was employed to test the hypothesized relationships.

Findings

The study found that the direct effect of personal and environmental factors significantly influences entrepreneurs' performance and opportunity recognition, and opportunity recognition significantly influences entrepreneurs' performance. The results further indicated that opportunity recognition mediates the relationships between environmental factors and entrepreneurs' performance, but not on the relationships between personal factors and entrepreneurs' performance.

Practical implications

The findings from the study guide SMEs entrepreneurs' performance by utilizing the opportunity recognition more efficiently and effectively. The study further enhances practitioners' understanding of the drivers and motivations of entrepreneurs within a developing nation context.

Originality/value

Although some previous studies already exist that discuss SMEs entrepreneurs' performance, there have been few studies focusing on opportunity recognition and mediation role of opportunity recognition, and far lesser in the context of a developing nation.
