The aim of the article was to compare the learning outcomes of the same content in the form of a traditional analogue lesson and in the form of a virtual reality (VR) lesson with the use of head-mounted display (HMD).

The study included one biology lesson conducted in 4 groups of a dozen people and one biology lesson in VR carried out individually on 75 people. The respondents completed the knowledge test, a questionnaire before and after the class regarding the attitude to new technologies, and feelings after the lesson. The researchers used detailed observation sheets (subjects' behaviour and the dynamics of the lesson). The obtained results were analysed statistically through lesson type (traditional/VR), respondent type (technology enthusiast/non-enthusiast) and question type. The Mann–Whitney U test, t-student and chi-squared (?²) test were used.

The average of the overall results in the knowledge test was similar in both groups (16 points; ±SD 2.13), slightly better for the analogue group and for the non-enthusiast group. It was found that VR hinders the acquisition of knowledge by tech enthusiasts, who perceive it primarily in the play paradigm. However, it encourages the learning of technology sceptics, who quickly discover a passion for exploring the virtual world. It was clearly indicated, quantitatively and qualitatively, how the technology modalities directly influenced the learning outcomes.

The article offers fresh insights into how students' perceptions of the educational process can be transformed through the integration of VR. The compelling findings and nuanced analysis provide a robust foundation for exploring new frontiers in educational technology.

Adoption of integrated MOS based pseudo-resistor (PR) structures instead of using off-chip passive poly resistors for analog circuits in complementary metal oxide semiconductor technology (CMOS) is an area-efficient way for realizing larger time constants. However, issue of common-mode voltage shifting and excess dependency on the process and temperature variations introduce nonlinearity in such structures. So there is dire need to not only closely look for the origin of the problem with the help of a thorough mathematical analysis but also suggest the most suitable PR structure for the purpose catering broadly to biomedical analog circuit applications.

In this work, incremental resistance (IR) expressions and IR range for balanced PR (BPR) structures operating in the subthreshold region have been closely analyzed for broader range of process-voltage-temperature variations. All the post-layout simulations have been obtained using BSIM3V3 device models in 0.18 µm standard CMOS process.

The obtained results show that the pertinent problem of common-mode voltage shifting in such PR structures is completely resolved in scaled gate linearization and bulk-driven quasi-floating gate (BDQFG) BPR structures. Among all BPR structures, BDQFG BPR remarkably shows constant IR value of 1 TΩ over −1 V to 1 V voltage swing for wider process and temperature variations.

Various balanced PR design techniques reported in this work will help the research community in implementing larger time constants for analog-mixed signal circuits.

The PR design techniques presented in the present piece of work is expected to be used in developing tunable and accurate biomedical prosthetics.

The BPR structures thoroughly analyzed and reported in this work may be useful in the design of analog circuits specifically for applications such as neural signal recording, cardiac electrical impedance tomography and other low-frequency biomedical applications.

Much of the vocabulary of digital rights have not been translated into Kiswahili. This means that technology experts and digital rights defenders often use English words when they are discussing technology. This contributes to the frailty of efforts to defend digital rights because those who attempt to explain the importance of these issues to the broader societies are forced to rely on English vocabulary that is not rooted in or connected to Kiswahili contexts. This paper aims to discuss the importance of inviting people to use African languages on the internet.

Kiswahili is the most widely spoken African language in the world. Nearly 140 million people in East Africa speak Kiswahili as a first or second language, including in Kenya and Tanzania where it is the national language. There is a long history of Kiswahili writing, publishing and cultural production in Kiswahili. Kiswahili is also the only African language that is an official language at the African Union. Even so, Kiswahili lags behind significantly in the development of a vocabulary and grammar of technology.

Beyond vocabulary, the use of African languages online is important to strengthening democracy on the internet because language is keenly connected to identity. Efforts to translate the vocabulary of technology into Kiswahili are aimed at encouraging societies in East Africa to build communities online that represent their interests keenly. This article therefore looks at the importance of language in building society and the efforts by residents of East Africa to decolonise the internet, so that they are able to exist in their fullness on the internet. The article further examines the semiotics of language in digital innovation, and the importance of representing Kiswahili language communities properly online in efforts to decolonise the internet. This paper does not presume that Kiswahili is the only African language that can decolonise the internet, because even Kiswahili has a history of domination over other language communities in the region. Rather, the article uses the example of Kiswahili to urge the use of indigenous languages to defend digital diversity.

The importance of this article is in demonstrating the importance of language in the movement to develop digital rights and especially to remove colonial approaches to technology, an issue that, to the best of the author’s knowledge, has never been discussed in relation to the Kiswahili language.

There is evidence that both hypnotherapy and virtual reality (VR) can be helpful in reducing perceived stress in the general population. This is a feasibility and acceptability trial of an intervention combining hypnotherapy and VR to establish its acceptability in students. This study aims to establish whether students found the experience acceptable, described any adverse effects and whether they reported feeling calmer after the experience.

The study was testing the hypothesis that students would attend the sessions and find the experience acceptable. A secondary hypothesis was that preliminary qualitative and quantitative evaluation of measures of stress and wellbeing would signal potential improvements.

All participants completed all three sessions. No side effects were reported. Visual analogue scales recorded each day assessing the immediate effect improved. At the end of the intervention, there was an increase in wellbeing of 2.40 (95% CI: 1.33, 3.53, p = 0.006), and a decrease in depression of 0.73 (95% CI: 0.40, 1.07, p = 0.010), reflecting large effect sizes of 0.76 and 0.83, respectively. Qualitative feedback was generally very positive.

This study is small with just 15 students and was over a short period of time. The recruitment method meant there was no way to establish whether the volunteer students were representative of the general student population in terms of mental wellbeing. There was no control arm.

The preliminary results suggest that a larger controlled trial is justified.

This VR experience may have benefit to university students and to the wider population.

This described the evaluation of a novel intervention for perceived stress combining hypnotherapy and virtual reality in a group of healthcare students, with promising results suggesting further evaluation is needed.

Maintaining the safety of the human is a major concern in factories where humans co-exist with robots and other physical tools. Typically, the area around the robots is monitored using lasers. However, lasers cannot distinguish between human and non-human objects in the robot’s path. Stopping or slowing down the robot when non-human objects approach is unproductive. This research contribution addresses that inefficiency by showing how computer-vision techniques can be used instead of lasers which improve up-time of the robot.

A computer-vision safety system is presented. Image segmentation, 3D point clouds, face recognition, hand gesture recognition, speed and trajectory tracking and a digital twin are used. Using speed and separation, the robot’s speed is controlled based on the nearest location of humans accurate to their body shape. The computer-vision safety system is compared to a traditional laser measure. The system is evaluated in a controlled test, and in the field.

Computer-vision and lasers are shown to be equivalent by a measure of relationship and measure of agreement. R² is given as 0.999983. The two methods are systematically producing similar results, as the bias is close to zero, at 0.060 mm. Using Bland–Altman analysis, 95% of the differences lie within the limits of maximum acceptable differences.

In this paper an original model for future computer-vision safety systems is described which is equivalent to existing laser systems, identifies and adapts to particular humans and reduces the need to slow and stop systems thereby improving efficiency. The implication is that computer-vision can be used to substitute lasers and permit adaptive robotic control in human–robot collaboration systems.

Both technological and human-centric perspectives need to be acknowledged when combining lean production practices and Industry 4.0 (I4.0) technologies. This study aims to explore and explain how lean production practices and I4.0 technologies may coexist to enhance the human-centric perspective of manufacturing operations in the era of Industry 5.0 (I5.0).

The research approach is an explorative and longitudinal case study. The qualitative data collection encompasses respondents from different job functions and organizational levels to cover the entire organization. In total, 18 interviews with 19 interviewees and five focus groups with a total of 25 participants are included.

Identified challenges bring forth that manufacturing organizations must have the ability to see beyond lean production philosophy and I4.0 to meet the demand for a human-centric perspective in socially sustainable manufacturing in the era of Industry 5.0.

The study suggests that while lean production practices and I4.0 practices may be considered separately, they need to be integrated as complementary approaches. This underscores the complexity of managing simultaneous organizational changes and new digital initiatives.

The research presented illuminates the elusive phenomena comprising the combined aspects of a human-centric perspective, specifically bringing forth implications for the co-existence of lean production practices and I4.0 technologies, in the transformation towards I5.0.

The study contributes to new avenues of research within the field of socially sustainable manufacturing. The study provides an in-depth analysis of the human-centric perspective when transforming organizations towards Industry 5.0.

Large-scale and complex issues tend to require a system of interconnected teams (i.e., multiteam systems) that offer more manpower, resources, and flexibility to meet more challenging demands. However, multiteam systems often work within “extreme environments” that can be very stressful, and the impact of this stress can deplete team members’ Well-Being and hinder team performance. Current research on multiteam systems does not address the need to understand how environmental stressors may impact component teams and overall team functioning and how multiteam systems in these environments can regulate stress to overcome these problems. NASA’s spaceflight multiteam system provides a unique example that organizational researchers can look at to understand how the Mission Control team helps regulate stress in the spaceflight team operating within an isolated, confined, and extreme environment. This chapter articulates how NASA’s spaceflight multiteam system stress regulation practices can inform organizational psychologists and advance our understanding of multiteam system functioning.

Gillette’s historically successful “razor and blade” business model (RBM) has been a promising benchmark for multiple businesses across diverse industries worldwide in the past several decades. The extant literature deals with very few nuances of this business model notwithstanding the fact that there are several variants of this business model being put to practical use by firms in diverse industries in grossly metaphorically equivalent situations.

This study adopts the 2 × 2 truth table framework from the domains of mathematical logic and combinatorics in fleshing out all possible (four logical possibilities) variants of the razor and blade business model for further analysis. This application presents four mutually exclusive yet collectively exhaustive possibilities on any chosen dimension. Two major dimensions (viz., provision of subsidy and intra- or extra-firm involvement in the making of razors or blades or both) form part of the discussion in this paper. In addition, this study synthesizes and streamlines entrepreneurial wisdom from multiple intra-industry and inter-industry benchmarks in terms of real-time firms explicitly or implicitly adopting several variants of the RBM that suit their unique context and idiosyncratic trajectory of evolution in situations that are grossly reflective of the metaphorically equivalent scenario of razor and recurrent blades. Inductive method of research is carried out with real-time cases from diverse industries with a pivotally common pattern of razor and blade model in some form or the other.

Several new variants of the razor and blade model (much beyond what the extant literature explicitly projects) have been discovered from the multiple metaphorically equivalent cases of RBM across industries. All of these expand the portfolio of options that relevant entrepreneurial firms can explore and exploit the best possible option chosen from them, given their unique context and idiosyncratic trajectory of growth.

This study has enriched the literature by presenting and analyzing a more inclusive or perhaps comprehensive palette of explicit choices in the form of several variants of the RBM for the relevant entrepreneurial firms to choose from. Future research can undertake the task of comparing these variants of RBM with those of upcoming servitization business models such as guaranteed availability, subscription and performance-based contracting and exploring the prospects of diverse combinations.

Smart entrepreneurial firms identify and adopt inspiring benchmarks (like razor and blade model whenever appropriate) duly tweaked and blended into a gestalt benchmark for optimal profits and attractive market shares. They target diverse market segments for tied-goods with different variants or combinations of the relevant benchmarks in the form of variegated customer value propositions (CVPs) that have unique and enticing appeal to the respective market segments.

Value-sensitive customers on the rise globally choose the option that best suits them from among multiple alternatives offered by competing firms in the market. As long as the ratio of utility to price of such an offer is among the highest, even a no-frills CVP may be most appealing to one market segment while a plush CVP may be tempting to yet another market segment simultaneously. While professional business firms embrace resource leverage practices consciously, amateur customers do so subconsciously. Each party subliminally desires to have the maximum bang-to-buck ratio as the optimal return on investment, given their priorities ceteris paribus.

Prior studies on the RBM have explicitly captured only a few variants of the razor and blade model. This study is perhaps the first of its kind that ferrets out many other variants (more than ten) of the razor and blade model with due simplification and exemplification, justification and demystification.

This study aims to examine member attachment in hybrid identity organizations (HIOs), assessing the distinct effects of identification with respect to two elements (normative and utilitarian) of a hybrid’s identity. Specifically, the author explored how such dual identifications influence commitment and exit/voice/loyalty.

To distinguish the effects of the two identities, the author used the mechanism of identity congruence – the gap between identity perceptions and expectations – as an analog of identification. The models of identity gap, commitment and exit/voice/loyalty were examined via a survey of agricultural cooperative members.

Both the social and economic forms of identity gap were significantly related to commitment and exit/voice/loyalty. In addition, commitment mediated the relationship between identity gap and exit/voice/loyalty.

The results demonstrate the distinctive effects of the dual identities and reinforce the importance of delineating such differences when examining identification in hybrid organizations.

Managers should recognize the duality inherent in hybrid organizational identification and understand the potential for different outcomes stemming from the separate identities.

This study represents the first quantitative examination of an integrated model of dual identification and commitment in HIOs. It is also unique in exploring the exit/voice/loyalty framework as a consequent of identification.
