This study aims to reduce data bias during human activity and increase the accuracy of activity recognition.

Abstract

Purpose

This study aims to reduce data bias during human activity and increase the accuracy of activity recognition.

Design/methodology/approach

A convolutional neural network and a bidirectional long short-term memory model are used to automatically capture feature information of time series from raw sensor data and use a self-attention mechanism to learn select potential relationships of essential time points. The proposed model has been evaluated on six publicly available data sets and verified that the performance is significantly improved by combining the self-attentive mechanism with deep convolutional networks and recursive layers.

Findings

The proposed method significantly improves accuracy over the state-of-the-art method between different data sets, demonstrating the superiority of the proposed method in intelligent sensor systems.

Originality/value

Using deep learning frameworks, especially activity recognition using self-attention mechanisms, greatly improves recognition accuracy.

Abstract

Purpose

As an advanced manufacturing method, additive manufacturing (AM) technology provides new possibilities for efficient production and design of parts. However, with the continuous expansion of the application of AM materials, subtractive processing has become one of the necessary steps to improve the accuracy and performance of parts. In this paper, the processing process of AM materials is discussed in depth, and the surface integrity problem caused by it is discussed.

Design/methodology/approach

Firstly, we listed and analyzed the characterization parameters of metal surface integrity and its influence on the performance of parts and then introduced the application of integrated processing of metal adding and subtracting materials and the influence of different processing forms on the surface integrity of parts. The surface of the trial-cut material is detected and analyzed, and the surface of the integrated processing of adding and subtracting materials is compared with that of the pure processing of reducing materials, so that the corresponding conclusions are obtained.

Findings

In this process, we also found some surface integrity problems, such as knife marks, residual stress and thermal effects. These problems may have a potential negative impact on the performance of the final parts. In processing, we can try to use other integrated processing technologies of adding and subtracting materials, try to combine various integrated processing technologies of adding and subtracting materials, or consider exploring more efficient AM technology to improve processing efficiency. We can also consider adopting production process optimization measures to reduce the processing cost of adding and subtracting materials.

Originality/value

With the gradual improvement of the requirements for the surface quality of parts in the production process and the in-depth implementation of sustainable manufacturing, the demand for integrated processing of metal addition and subtraction materials is likely to continue to grow in the future. By deeply understanding and studying the problems of material reduction and surface integrity of AM materials, we can better meet the challenges in the manufacturing process and improve the quality and performance of parts. This research is very important for promoting the development of manufacturing technology and achieving success in practical application.

Abstract

After the global financial crisis, many countries deregulated their banking sectors. The banking sector has become the major funding supplier in most emerging countries. Bank in Indonesia has provided an essential role as an intermediary institution in matching up surplus and deficit parties with a relatively concentrated market structure. Moreover, banks should innovate and diversify to provide excellent products and services to their customers and win the market. More diversified banks are expected to have better performance and more resilience, especially during a crisis. This study examines the relationship among bank market power, diversification, and bank stability of listed bank companies in Indonesia from 2008 to 2020. This study employs a two-step system GMM to deal with potential endogeneity. This study finds that banks’ market power and diversification affect bank stability, and the presence of crisis encourages banks to be more prudent. The result of this study provides insightful implications for academics and policy-makers.

Abstract

Purpose

The purpose of this study was to explore potential witnesses' memories for a day that was experienced an unremarkable. There may be instances in an investigation in which all leads have been exhausted, and investigators use a broad appeal for witnesses who may have witnessed something important. Investigators can benefit from knowing the types of information that may be recalled in such circumstances, as well as identifying specific methods that are effective in eliciting useful information.

Design/methodology/approach

The present study explored how the delay to recall and recall method influenced the recollection of a seemingly unremarkable day that later became important. Participants were asked to recall an experienced event that occurred either recently (a few weeks prior) or in the distant past (a year prior). Participants recalled via either a written method, in-person individual-spoken or collaborative-spoken interviews.

Findings

Results suggest an independent benefit for individual-spoken in-person recall (compared to written or collaborative-spoken recall) and recall undertaken closely after an event (compared to delayed recall). Both individual-spoken interviews as well as more recent recollection resulted in a greater number of overall details recalled. The authors further examined the types of details recalled that might be important to progressing an investigation (e.g. other witnesses and records).

Originality/value

The present work provides important implications for interviewing witnesses about a seemingly unremarkable event that later became important.

Abstract

In these uncertain and risky times, the work that educators and educational researchers carry out may feel inconsequential. In preparing young people to live well in a world worth living in, educators must consider, firstly, what roles they can play in a global environment riven by volatile economic, social, and environmental contexts, and secondly, the responsibilities they bear as researchers to produce forms of understanding, modes of action, and ways of relating to one another and this world.

In this chapter, we introduce the pedagogy, education, and praxis (PEP) network and how it is that we, as researchers from around the world, came together to discuss our researching practices in coming to know and explore educational research problems concerning equity, diversity and social justice within and across different cultural settings. We share short stories of ourselves to reveal how it is that we have come to know, be, and act as researchers in our projects and how working alongside each other – our mutual relatings – have generated further understanding about our own and each other’s researching practices.

This chapter establishes the purpose of the book, where we share empirical work through the lens of practice architectures. For instance, what is considered to be an educational equity problem across international or cross-cultural sites? What are considered acceptable forms of evidence of coming to understand educational inequity in its diverse forms in different sites? How are taken-for-granted research practices enabling and/or constraining different forms of understandings about educational inequity, including the issues to be researched and/or the direction of the research project? We then provide an overview of the remaining chapters.

Abstract

Purpose

This study aims to test and analyze the effect of continuous commitment, task complexity, competence and personal value on employee performance millennial intervening job satisfaction.

Design/methodology/approach

This research method is quantitative with a sequential explanatory design, then data collection through a questionnaire, with a sample of 205 respondents—data analysis using Structural Equation Model (SEM) with the software Linear Structural Relationship (LISREL).

Findings

The results of research on the performance of millennial employees with intervening work satisfaction showed that continuous commitment (2.49), task complexity (2.74) and professional competence (2.0) had a significant effect. This means that the performance of millennial employees will increase if they get job satisfaction. With satisfaction, the commitment and competence of millennial employees are high. While the research results for the performance of millennial employees have a direct influence, only professional competence (2.27) and task complexity (4.06) are significant. This means that as high as professional competence is characterized by intellectual, emotional mood and attitude, owned by millennial employees, the resulting performance is increased even with complex tasks.

Research limitations/implications

The findings of this study have significance for enhancing organizational performance so that businesses can maximize the performance of millennial employees by paying attention to job satisfaction, professional competence and personal values.

Originality/value

This research's contribution to millennial workers is to help them improve and develop their performance, allowing them to compete more effectively. The findings of this study have significance for enhancing organizational performance so that businesses can maximize the performance of millennial employees by paying attention to job satisfaction, professional competence and personal values.

This study aims to show the factors that influence the intention of Generation Z Muslims to buy halal food products through ShopeeFood.

Abstract

Purpose

This study aims to show the factors that influence the intention of Generation Z Muslims to buy halal food products through ShopeeFood.

Design/methodology/approach

This study used quantitative methods. The analytical technique used is partial least square-structural equation modeling with 230 respondents as a sample of Generation Z Muslims in West Java, Indonesia. This research was conducted in June 2022 by distributing questionnaires via Google Forms and social media.

Findings

The results showed that perceived ease of use, perceived usefulness, attitudes, subjective norms, perceived behavioral control, religiosity and intention to buy halal food through ShopeeFood in Generation Z Muslims in West Java were in the high category. However, subjective norms and perceived behavioral control are the only ones that positively and significantly affect purchase intention.

Practical implications

ShopeeFood is expected to be able to identify and take advantage of the high level of intention of Generation Z Muslims to buy halal food through ShopeeFood. ShopeeFood can socialize and increase consumer attention that ShopeeFood is different from other online food delivery services. ShopeeFood can require merchants to display transparency in the composition of food products.

Originality/value

To the best of the authors’ knowledge, this study is perhaps the first study in the context of Generation Z Muslims in West Java, Indonesia, that deals with the perceived ease of use, perceived usefulness, attitudes, subjective norms, perceived behavioral control and religiosity on the intention to buy halal food through ShopeeFood. The study’s findings are essential in Islamic marketing and technological acceptance (ShopeeFood Apps).

Abstract

Purpose

This study aims to empirically explore several factors that encourage muzakki (zakat payers) to pay their zakat through institutions by elaborating on their extrinsic and intrinsic motivations as the composite factors regarding the attitude and intention improvement of muzakki. This study specifically studies zakat payment via digital means and categorizes the muzakki groups into two (urban and suburban) to be considered in the results.

Design/methodology/approach

Overall, this study gathers the data from 298 muzakki using a partial least squares technique the multigroup analysis to compare the analysis.

Findings

This study found that different sociodemographic aspects will result in varied performances of motivation in using technology between the two groups. Furthermore, positive preference aspects, such as muzakki’s attitude, can be a catalyst in improving their motivation to pay zakat through institutions.

Practical implications

The findings of this study can be used as a foundation to improve the technology-based services that will be more accessible and reachable. Provision of technical follow-ups regarding the utilization of technology, including community-based digital platform socializations, availability of online customer service that will respond to muzakki’s needs and synergy between stakeholders, are the primary obligations that a zakat institution must fulfill.

Originality/value

As far as the researchers are concerned, the studies focusing on the motivational factors and attitude of muzakki as an intervention in paying zakat via institutions are limited in numbers, especially studies on digital payment. In this study, however, classifying the groups into two will help gain a deeper understanding of this topic.
