As technology becomes more widely accessible, there is a growing concern about internet gaming disorder (IGD) around the world. The aim of this study is to evaluate the prevalence of IGD and also assess the effects of depression, anxiety, stress and insomnia levels on the IGD of youths in Bangladesh.

A cross-sectional quantitative study design was used to collect data from the youths of different locations in Bangladesh between October 21, 2023 and January 15, 2024. A total of 501 samples were collected using the convenience sampling technique. The following measurement scales were Internet Gaming Disorder Scale short form, depression, anxiety and stress scales and insomnia severity index, which were used to assess scores for IGD, psychological distress and insomnia, respectively.

The study found that the prevalence of IGD was 9.8%. IGD was shown to be significantly associated with depression, anxiety and stress. Aside from that, IGD and insomnia had a significant association, as did a friendly family environment.

The generalizability of the results could be improved by conducting additional studies with a more diverse sample, such as the general population or a different age group.

The study will help the government reduce the prevalence of IGD, improving the mental and physical health of youth.

No research has been conducted on youth and different professions in Bangladesh. There has also been very little research on the prevalence of gaming addiction and mental health.

This case study aims to simulate the learners’ thoughts about the earnest comprehension of sustainable brands with zero waste policy. It will further prompt them to anatomize the growth strategy of a sustainable brand, as it delineates the challenges faced by a woman ecopreneur. In response to these causative conundrums, the incumbent would be able to develop an understanding on the evolving landscape in context to the association between meeting consumer expectations, brand positioning and its channelization towards growth and revenue generation. Furthermore, the learners will be able to analyse the stages of product life cycle of a sustainable product and recommend an effective strategic plan to meet the consumer expectations and achieve desired growth by the application of Kano model.

Thenga was a home-grown brand from Kerala (God’s own country) founded by Maria Kuriakose, a native of Kerala in 2019. Unlike other brands, which were using coconut as a source of flesh, water and oil, Kuriakose came up with an idea of using the tossed shells of coconuts which eventually used to end up at landfills. These shells were crafted into aesthetics by the team of Thenga while adhering to the zero-waste policy. The brand gained momentum with the overwhelming positive response from the natives of Kerala and carved a way across the boundaries of Kerala, gradually reaching to every corner of India. Kuriakose thought of scaling the brand in the international boundaries as well. Within no time, the brand was a success. However, over the time, the brand was confronted with two broad dilemmas. First, non-uniformity in the sizes of the products, especially in bulk orders where maintaining uniformity was essential. The customers complained that there was no uniformity in the size of the products because for gifting purposes, they wanted all the products to look alike. And second, selecting the stringent quality shells because the ones exposed to sun for a very long time were not ideal for crafting the products due to the cracking of the shells, thereby affecting their durability. It became difficult addressing to these complex issues because the shells were nature’s creations. These issues were very different from the managerial dilemmas. Would the perspectives of management provide a solution? Kuriakose had to find a way out in the long term for the survival of the brand especially during its growth phase.

The case study is relevant for students in disciplines of entrepreneurship, green marketing, brand management, corporate social responsibility and strategy. It is designed for advanced MBA/PGDM and capstone courses. The case study also addresses the elements of customers’ perceptions towards innovative products and can be used as an addition for marketing courses dealing with strategies to improve the awareness and adoption of sustainable products.

The purpose of this paper is to develop a familiarity analysis of resistive-capacitive (RC) network active circuit operating with unfamiliar low-pass (LP) type negative group delay (NGD) behavior. The design method of NGD circuit is validated by simulation with commercial tool and experimental measurement.

The present research work methodology is structured in three main parts. The familiarity theory of RC-network LP-NGD circuit is developed. The LP-NGD circuit parameters are expressed in function of the targeted time-advance. Then, the feasibility study is based on the theory, simulation and measurement result comparisons.

The RC-network based LP-NGD proof of concept is validated with −1 and −0.5 ms targeted time-advances after design, simulation, test and characterized. The LP-NGD circuit unity gain prototype presents NGD cut-off frequencies of about 269 and 569 Hz for the targeted time-advances, −1 and −0.5 ms, respectively. Bi-exponential and arbitrary waveform signals were tested to verify the targeted time-advance.

The performance of the unfamiliar LP-NGD topology developed in the present study is limited by the parasitic elements of constituting lumped components.

The NGD circuit enables to naturally reduce the undesired delay effect from the electronic and communication systems. The NGD circuit can be exploited to reduce the delay induced by electronic devices and system.

As social impacts of the NGD circuit application, the NGD function is one of prominent solutions to improve the technology performances of future electronic device in term of communication aspect and the transportation system.

The originality of the paper concerns the theoretical approach of the RC-network parameters in function of the targeted time-advance and the input signal bandwidth. In addition, the experimental results are also particularly original.

Wellness has moved beyond its original emancipatory roots to become a mechanism for self-optimisation. In this chapter, the authors examine how wellness transforms or ‘wellness washes’ pleasurable practices into rationalised and instrumentalised ones. The authors argue that one of the key drivers of ‘wellness washing’ is the entanglement of wellness with and in contemporary workplaces. In advance of this analysis, the authors examine digital pleasures, ASMR and digital drugs to examine how pleasures mediated and afforded by the screen are ‘wellness washed’ to better position them as normative cultural practices.

Drones will become part of daily lives similar to smartphones becoming a staple of modern living. Nonetheless, only several past studies investigated the intention to utilise drones for parcel delivery however, the intention to use drones among online shoppers was not fully explored. The study attempts to investigate the factors influencing the intention to use drones for last-mile delivery.

A total of 292 data were gathered via an online survey among online shoppers applying a snowball sampling method. Since the study operationalised the measures as composites, a combination of reflective and formative measurement, and the study focusses on predictive purposes, partial least squares structural equation modelling with SmartPLS 4 was applied to test the model developed based on the stimulus-organism-response model.

The analysis found that all the direct hypotheses were found supported. Moreover, Green support, green desire and pro-environmental behaviour positively and sequentially mediated future orientation and intention, whereas technology anxiety and perceived safety moderated the relationship between pro-environmental behaviour and intention.

The respondents only limit to the online shoppers in Malaysia which based on purposive sampling method, thus the findings cannot be generalized to another countries.

Besides enriching the literature on drone studies, the findings provided practical insights to online platforms and drone operators to develop an effective strategy to encourage online shoppers to shift from conventional delivery to drone delivery.

The study developed a new model for drone delivery studies using the S-O-R model in introducing orientation towards the future and green support as the stimulus, green desire as an organism and pro-environmental behaviour and usage intention as a response. The study introduced multiple sequential mediators, also contributing to the S-O-R model to predict online shoppers' behaviour towards drones as a tool for last-mile delivery. Another important contribution, technology anxiety and perceived safety were confirmed to have a moderation effect for the relationship between pro-environmental behaviour and intention to use drones for last-mile delivery.

Dietary components have been mentioned as modifiable risk factors in the development of gallstone disease (GSD), but it has been less addressed. The present study aimed to investigate the potential association between different types of dietary carbohydrate and the risk of gallstone.

In this case-control study 189 patients diagnosed with GSD as a case group and 342 people as a control group were enrolled. Dietary intake of the participants was collected through a 168-item semi-quantitative food frequency questionnaire. Total intakes of calories, macronutrients and different types of carbohydrate were estimated. Crude and multivariable-adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to assess the association between carbohydrate intake and GSD.

Patients with gallstone consumed significantly more fructose and sucrose and less fiber. After fully adjustment, the logistic regression indicated significant association between GSD with dietary intake of total carbohydrate (OR = 1.65, 95% CI: 1.1–2.4, p = 0.009), sugar (OR = 1.23, 95% CI: 0.8–1.7, p = 0.014), fructose (OR = 2.5, 95% CI: 1.7–3.9, p < 0.001), glucose (OR = 1.9, 95% CI: 1.3–2.9, p = 0.002) and sucrose (OR = 1.37, 95% CI: 0.9–1.6, p = 0.042). Also, increasing intakes of lactose, galactose and maltose were associated with a decrease in the risk of GSD, but not statistically significant, although lactose was close to significance (OR = 0.71, 95% CI: 0.48–1, p = 0.051).

There is a positive and significant relationship between total carbohydrate, sugar, fructose, glucose and sucrose intake and the occurrence of gallstone.

This correlational study conducted at Ban Phaeo Hospital, Thailand, aimed to assess the health literacy levels of 105 older adult stroke survivors from November 2021 to February 2022.

The study uncovered a moderate level of health literacy among participants, as indicated by a mean score of 66.85 (SD = 8.151).

Significant positive correlations were observed between health literacy and several key factors, including patient-provider relationships (r = 0.550, p < 0.001), social support (r = 0.548, p < 0.001) and perceived health status (r = 0.484, p < 0.001). These findings emphasize the interconnectedness of health literacy with critical elements of healthcare engagement and well-being.

To advance stroke prevention in the older adult population, future research should focus on evaluating nurse-led interventions designed to enhance health literacy.

Raising awareness about the influence of patient-provider relationships, social support networks and perceived health status represents the initial stride toward a successful strategy for elevating health literacy and preventing recurrent strokes in this demographic.

This work is entirely original, all authors listed contributed to the project and have approved the final draft for submission.
