Abstract

Purpose

The purpose of this paper was to investigate how variations in the geometry of silicon chips and the presence of surface defects affect their static bending properties. By comparing the bending radius and strength across differently sized and treated chips, the study sought to understand the underlying mechanics that contribute to the flexibility of silicon-based electronic devices. This understanding is crucial for the development of advanced, robust and adaptable electronic systems that can withstand the rigors of manufacturing and everyday use.

Design/methodology/approach

This study explores the impact of silicon chip geometry and surface defects on flexibility through a multifaceted experimental approach. The methodology included preparing silicon chips of three distinct dimensions and subjecting them to thinning processes to achieve a uniform thickness verified via scanning electron microscopy (SEM). Finite element method (FEM) simulations and a series of four-point bending tests were used to analyze the bending flexibility theoretically and experimentally. The approach was comprehensive, examining both the intrinsic geometric factors and the extrinsic influence of surface defects induced by manufacturing processes.

Findings

The findings revealed a significant deviation between the theoretical predictions from FEM simulations and the experimental outcomes from the four-point bending tests. Rectangular-shaped chips demonstrated superior flexibility, with smaller dimensions leading to an increased bending strength. Surface defects, identified as critical factors affecting flexibility, were analyzed through SEM and atomic force microscopy, showing that etching processes could reduce defect density and enhance flexibility. Notably, the study concluded that surface defects have a more pronounced impact on silicon chip flexibility than geometric factors, challenging initial assumptions and highlighting the need for defect minimization in chip manufacturing.

Originality/value

This research contributes valuable insights into the design and fabrication of flexible electronic devices, emphasizing the significant role of surface defects over geometric considerations in determining silicon chip flexibility. The originality of the work lies in its holistic approach to dissecting the factors influencing silicon chip flexibility, combining theoretical simulations with practical bending tests and surface defect analysis. The findings underscore the importance of optimizing manufacturing processes to reduce surface defects, thereby paving the way for the creation of more durable and flexible electronic devices for future technologies.

Abstract

Purpose

This paper aims to explore how the term “mental health literacy” (MHL) is defined and understand the implications for public mental health and educational interventions.

Design/methodology/approach

An extensive search was conducted by searching PubMed, ERIC, PsycINFO, Scopus and Web of Science. Keywords such as “mental health literacy” and “definition” were used. The publication year ranges from 1997 to 2023.

Findings

In total, 17 papers met the inclusion criteria. Three distinct themes characterise the definitions of MHL: cognitive understanding; affective empowerment; and behavioural change. In the mental health educational context, inspiration, transformation and practice can be viewed as three stages for curriculum development.

Research limitations/implications

Despite conducting a systematic literature review, there remains the possibility that certain relevant studies may not have been identified. Specifically, the selection criteria prioritise papers that explicitly addressed MHL.

Practical implications

Traditional educational approaches prioritise knowledge dissemination and attitude change; integrating MHL into mental health well-being curriculum advocates for action-oriented intervention to address mental health challenges.

Social implications

Understanding different definitions and concepts in a field can be valuable for consolidating shared understandings, highlighting tensions and contradictions, and enhancing communication among researchers. Ironically, perhaps, the process also highlights the provisional nature of these definitions.

Originality/value

The exploration of MHL with three themes of definitions sheds light on the understanding of this concept. Three core themes in MHL definitions guide future curriculum development. This study underscores the importance of prioritise action-oriented intervention in mental health education, emphasising the need to move beyond knowledge dissemination towards transformative practices that promote holistic mental well-being.

Abstract

Purpose

The persistence and virality of conspiracy theories online have raised significant concerns. This study revisits Rogers’ Diffusion of Innovations theory to examine the spread of conspiracy theories on social media, specifically focusing on how factors influencing their diffusion evolve over time.

Design/methodology/approach

The study analyzes over 1.18 million COVID-19-related tweets using a combination of natural language processing, social network analysis and machine learning techniques. It explores the dynamic roles of novelty, content negativity, influencers, echo chamber members and social bots in the diffusion of conspiracy theories.

Findings

The results indicate that novelty, influencers, echo chamber members and social bots are positively associated with the spread of conspiracy theories. The initial dissemination of conspiracy theories is primarily driven by content novelty and influencer involvement. Over time, the perpetuation of these theories becomes increasingly influenced by content negativity and the involvement of echo chamber members and social bots. Social bots serve as important connectors within echo chambers and their removal significantly reduces network cohesion.

Practical implications

The findings provide practical guidance for social media platforms and policymakers in monitoring diffusion patterns and applying targeted interventions.

Originality/value

This study introduces a time-sensitive approach to understanding the spread of conspiracy theories on social media. By identifying the key drivers at different stages of the diffusion process, this study offers valuable insights for developing effective strategies to counteract the proliferation of conspiracy theories at various points in their lifecycle.

Abstract

Purpose

The study aims to understand the phenomenon of workplace ostracism from multiple perspectives (target, perpetrator and observer). The understanding of the phenomenon is used to thematically analyse the antecedents of workplace ostracism and identify appropriate strategies for each antecedent.

Design/methodology/approach

The study findings are based on face-to-face semi-structured interviews with thirty-three senior and medium-level employees from various public and private sector organizations in India. The interview transcripts were systematically analyzed to identify antecedents of ostracism, which were inductively grouped together based on similarity.

Findings

The antecedents of workplace ostracism were grouped into four major heads: perceived non-alignment with organizational needs; emotional reaction; unconscious social processes and structural and demographic differences. Based on interview transcripts, strategies to reduce the effect of each of the broad antecedents of ostracism were identified.

Practical implications

Workplace ostracism has been linked with multiple negative outcomes including increased stress and turnover intention. The study provides managers with a framework that enables them to evaluate and understand incidences of ostracism among their subordinates. The study also equips managers with the knowledge of specific strategies for dealing with specific antecedents of ostracism.

Originality/value

The study answers the need to look at the phenomenon of ostracism through multiple perspectives. It identifies multiple potentially new antecedents and strategies to deal with workplace ostracism and groups them in a coherent manner. It is among the few studies on ostracism in India and extends the generalizability of the construct.

Abstract

Purpose

This study conducts an analysis of the interplay between governance quality, environmental expenditure of the government, and pollution emissions (measured as CO2 emissions) within the BRIC economies.

Design/methodology/approach

Utilizing the FMOLS model and marginal effects, we investigate the influence of governance quality and environmental expenditure on environmental quality (CO2 emissions) over the period 1996–2020. We took data for Brazil, Russia, India and China. We excluded South Africa due to its due to its small economic size relative to other BRIC economies, sluggish industrial growth and deteriorating foreign trade which gives contrast outliers to our data.

Findings

Results indicate that government investments in environmental protection contribute to a reduction in CO2 emissions. However, the effectiveness of these expenditures is contingent upon the quality of governance. This underscores the significance of robust governance for realizing meaningful reductions in air pollution through environmental spending. Further, increase in GDP per capita and the industrial sector's share of GDP are associated with a significant rise in CO2 emissions across BRIC economies. Conversely, FDI and trade openness exhibit a negative impact on CO2 emissions, with this effect gaining greater resilience when accounting for governance factors.

Research limitations/implications

Like any other studies, the present study also suffers from some limitations. First, besides air quality, environmental quality encompasses multiple dimensions and various characteristics such as water purity, noise pollution, open space access, visual effects of buildings etc. But the present study included only CO2 (air quality) as a proxy of environmental quality due to various problems of data and methods. Second, CO2 (carbon dioxide) emission, which is the dependent variable in our model, is actually influenced by various quantitative and qualitative (both natural and man-made) factors. We included only nine independent variables. However, we could not include many variables due to lack of consistent data. Third, this study included only four countries – Brazil, Russia, India and China (BRIC) and excluded South Africa which is a member of the BRICS block due to its economic size, sluggish industrial growth and deteriorating foreign trade which gives contrast outliers to our data set of the four BRIC countries. Therefore, the future research may be carried out by addressing those issues for better understanding of the environmental problems, governance and policies thereon.

Practical implications

(i) Establish environmental governance committees – The four BRIC countries including South Africa should form a committee comprising government, civil society, and private sector representatives for comprehensive oversight and collaboration in environmental governance. (ii) Invest in capacity building for environmental institutions – Allocate resources to enhance environmental institutions' capacity through training, data improvement, and enforcement strengthening. (iii) Implement green procurement policies – Encourage green procurement in government agencies to drive demand for eco-friendly products and services, promoting sustainable practices. (iv) Incentivize green technology development – Offer tax credits or subsidies to stimulate green technology adoption, including renewable energy and sustainable agriculture. (v) Promote sustainable urban development – Prioritize sustainable urban strategies like public transportation investment and green space promotion to mitigate urbanizations' environmental impacts. (vi) Enhance cross-border cooperation – Foster collaboration on transboundary environmental issues among four BRIC nations including South Africa, including joint research and policy responses. (vii) Promote green finance and investment – Mobilize green finance to support sustainable development projects through instruments like green investment funds and bonds.

Originality/value

This study distinguishes itself by offering a unique analysis of both individual and combined effects of governance and environmental expenditure on environmental quality. Additionally, it encompasses various dimensions of governance, an aspect rarely explored in the BRIC countries.
