This paper presents a detailed review of the numerical modeling of inductively coupled air plasmas under local thermodynamic equilibrium and under chemical non‐equilibrium. First, the physico‐chemical models are described, i.e. the thermodynamics, transport phenomena and chemical kinetics models. Particular attention is given to the correct modelling of ambipolar diffusion in multi‐component chemical non‐equilibrium plasmas. Then, the numerical aspects are discussed, i.e. the space discretization and iterative solution strategies. Finally, computed results are presented for the flow, temperature and chemical concentration fields in an air inductively coupled plasma torch. Calculations are performed assuming local thermodynamic equilibrium and under chemical non‐equilibrium, where two different finite‐rate chemistry models are used. Besides important non‐equilibrium effects, we observe significant demixing of oxygen and nitrogen nuclei, which occurs due to diffusion regardless of the degree of non‐equilibrium in the plasma.

The ubiquity of mobile phone use has generated a common phenomenon called phubbing, a reference to snubbing someone in social settings and instead concentrating on one's phone. Despite numerous adverse effects of phubbing argued in previous research, the group of phubbers is growing intensively. The purpose of this study is to investigate the potential transmission of phubbing between marital partners to raise public awareness of the propagation of phubbing.

A two-wave study with a 3-month interval was conducted, using matched husband–wife data from 253 Chinese couples. Husbands and wives separately completed questionnaires about their spouses’ phubbing and their marital quality. The dyadic data analysis method was applied to test the research hypotheses.

The results confirm the transmission of phubbing and show a pronounced gender asymmetry in the process of phubbing transmission. Phubbing could be transmitted from wives to husbands, but not vice versa. Specifically, only wives' phubbing significantly undermine relationship quality, while relationship quality was negatively related to both husbands' phubbing and wives' phubbing.

This study contributes to a better understanding of the mechanism of phubbing transmission and provide support for reciprocity theory and social role theory. Results can cause public attention to the transmissibility of phubbing and provide enlightenment on the management of personal phone behavior and offer insight into research on technology use in other types of interpersonal relationships.

Young people’s attachment to their smartphones is well-documented, with smartphones often described as prostheses. While prior studies typically assume a clear human/machine divide, this paper aims to build on posthuman perspectives, exploring intercorporeality, the blurring of human/technology boundaries, between emerging adults and their smartphones. The paper aims to discuss these issues.

Drawing on assemblage theory, this interpretive study uses smartphone diaries and friendship pair/small group discussions with 27 British emerging adults.

Participants in this study are characterized as homo prostheticus, living with and through their phones, treating them as extensions of their mind and part of their selves as they navigated between their online and offline, private and social lives. Homo prostheticus was part of a broader assemblage or amalgamation of human and non-human components. As these components interacted with each other, the assemblage could be strengthened or weakened by various technological, personal and social factors.

These qualitative findings are based on a particular sample at a particular point in time, within a particular culture. Further research could explore intercorporeality in human–smartphone relationships among other groups, in other cultures.

Although other studies have used prosthetic metaphors, this paper contributes to understanding of smartphones as a prostheses in the lives of emerging adults, highlighting intercorporeality as a key feature of homo prostheticus. It also uses assemblage theory to contextualize homo prostheticus and explores factors strengthening or weakening the broader human–smartphone assemblage.

Prioritizing should be a company’s No. 1 virtue. In the absence of priority, companies flounder, and employees become distracted. This inevitably leads to missed deadlines, over‐extended budgets, and a resulting output different from what was originally intended. This is excruciatingly evident when implementing an information technology (IT) strategy. Few industries can compete with the heap of wasteful, incomplete, and underutilized projects IT has amassed over the past two decades. The core of the problem is not the technology, but a failure clearly to define priorities at all levels in a company.

Educational institutions have a special social responsibility to initiate processes of sustainability transformation in society, nevertheless, activities that effectively address students as well as employees are rather moderate. To initiate change alongside strategic and political decisions, this paper aims to present findings of a gamification intervention (hereafter referred to as climate duel), which was implemented in a field study and tested to assess its potential as a supporting and transformative approach in a university context.

A three-month field study was conducted with two universities of applied sciences. The study included an environmental impact analysis of the two participating university departments, the conception and testing of the intervention and associated surveys to evaluate the effectiveness of the intervention in order to and to obtain feedback that would allow the duel to be scaled up at other universities or institutions.

Three hundred seventy-five people took part and saved 2.6 tons of greenhouse gas emissions through their participation in the climate duel and their corresponding behavioural changes. In addition, feedback from the participants yielded positive results in terms of behavioural changes and generated valuable evidence for future implementations. Nevertheless, there is still room for improvement, especially in terms of supporting communication activities that promote social relatedness to motivate each other, share experiences or deal with implementation difficulties in everyday life.

Building on the promising effects of gamification, the study is a showcase for applied science. With the possibility of testing a theory-based intervention in practice, an implementable, effective and scalable measure for universities that helps to accelerate the transformation process is available.

This study aims to understand the association between the fear of missing out (FOMO) and its impact on psychological well-being (PWB). The mediating effect of anxiety and moderating effects of social media engagement (SME) and resilience on the association mentioned above are also examined.

The study used a mix of attachment theory and cognitive-motivational-relational theory to understand the hypothesized relationship using a diverse sample of international respondents from South Asia, South East Asia and the Middle East. The data from 612 respondents was collected using SurveyMonkey. The authors have used Hayes’ PROCESS Macro to test the hypothesised relationships.

The results revealed that anxiety acts as a mediator between FOMO and PWB, while SME and resilience act as moderators in reducing the impact of FOMO on anxiety and the impact of anxiety on PWB, respectively.

The work extends the existing theorization and points out the merits of using SME and resilience as moderators and anxiety as a mediator for understanding the association between FOMO and PWB.

Emergent research suggests that compulsive social media usage (CSMU) has a correlational link with well-being. Previous research in this area primarily focused on the prevalence, dynamics and consequences of social media usage. However, the knowledge of these occurrences among school and university students is still in its infancy stage. This research study addresses the knowledge gap by investigating the nexus between fear of missing out (FOMO), phubbing, CSMU and well-being.

Cross-sectional surveys were conducted for collecting the data of school students and university students during COVID-19 when the exposure to the Internet and social media among the students had increased tremendously. Multivariate analysis and Moderated Mediated analysis techniques were performed to analyze the data using the structural equation modeling approach.

The results indicated that while on one side, students experience “FOMO”, on the other, they phone snub the individuals available to them to interact. FOMO significantly influences well-being; phubbing also has a significant impact on well-being; phubbing partially mediates the relationship between CSMU and well-being. However, for university students, the full mediation of phubbing in the relationship between CSMU and well-being was confirmed. It was also found that sleep fully mediated the relationship between CSMU and well-being.

This study provides novel highlights of the differential effects of FOMO, phubbing, sleep hygiene and well-being among the university and school-attending cohorts.

The key concern nowadays is smartphone addiction and user profiles. Following the risk and protective factors framework, the authors aim to characterize smartphone users according to two levels: (1) individual: referred to the use (i.e. boredom proneness, compulsive app downloading smartphone addiction) and (2) microsystem: referred to family and peers (i.e. family harmony and phubbing). Besides, the authors will derive useful managerial implications and strategies.

First, an extensive literature revision and in-depth interviews with experts were employed to identify the addiction-related variables at the individual and microsystem level. Second, information was collected from a sample of 275 Spanish smartphone users, and a K-means clustering algorithm was employed to classify smartphone users.

The proposed traffic lights schema identifies three users’ profiles (red, yellow and green) regarding their smartphone addiction and considering individual and microsystem critical variables.

This study proposes a practical and pioneer traffic lights schema to classify smartphone users and facilitate each cluster's strategies development.
