Abstract

Purpose

Irregular windy loads are loaded for a wind turbine. This paper aims to determine the form of gear failure and the working life of the gear system by assessing the dynamic strength of gears and dynamic stress distribution.

Design/methodology/approach

The helical planetary gear system of the wind turbine growth rate gearbox was investigated, and while a variety of clearance and friction gear meshing processes were considered in the planetary gear system, a finite element model was built based on the contact–impact dynamics theory, solved using the explicit algorithm. The impact stress of the sun gear of the planetary gear system was calculated under different loads. An integrated planetary gear meshing stiffness, and the error of system dynamic transmission error were investigated when the planetary gear meshes with the sun or ring gears.

Findings

The load has little effect on the sun gear of the impact stress which was known. The varying stiffness is different while the planetary gear meshes with the sun and ring gears. There were differences between the planetary gear system and the planetary gear, and with load, the planetary gear transmission error decreases.

Originality/value

This study will provide basis knowledge for the planetary gear system.

Abstract

Purpose

This paper aims to examine the impact of information and telecommunication technologies (ICT-proxied by mobile phone subscription and Internet usage) on carbon dioxide (CO2) emissions in the Organization for Economic Cooperation and Development (OECD) countries from 1990 to 2018.

Design/methodology/approach

The Cross-section Autoregressive Distributed Lag (CS-ARDL) model is employed to address the potential cross-section dependence problem. Common Correlated Effects Mean Group (CCEMG) and Augmented Mean Group (AMG) estimators are used to test for robustness of results.

Findings

Results reveal contrasting effects of mobile phone subscription and Internet usage on CO2 emissions. While mobile phone penetration helps mitigate CO2 emissions, Internet usage tends to increase the emissions. Findings show that renewable energy is beneficial to the environment while economic growth is harmful to the environment. The effects of financial development and trade openness seem negligible.

Practical implications

This study offers practical implications for policymakers. As different proxies of ICT could have contradictory impact on CO2, governments should be cautious against utilizing ICT to mitigate CO2. Findings point to the benefits of renewable energy in alleviating CO2 emissions. Therefore, governments are strongly advised to implement policies facilitating renewable energy consumption.

Originality/value

Previous studies ignored the problem of cross-section dependence which could lead to biased results and cause misleading inferences. This study aims to fill this void in the literature.

Abstract

Purpose

This study aims to examine the effects of industrialization, deindustrialization and financialization on Turkey’s energy insecurity by controlling the impacts of urbanization and alternative energy generation for the 1980–2018 period.

Design/methodology/approach

This study proposed an econometric model relying on the literature. Moreover, based on different financialization variables, this study estimated two specifications of this model using the augmented nonlinear autoregressive distributed lag approach.

Findings

The results are as follows: first, industrialization increased Turkey’s long-run energy insecurity, whereas deindustrialization did not affect Turkey’s energy security. Second, urbanization worsened Turkey’s energy insecurity. Third, financialization aggravated Turkey’s energy insecurity. Last, alternative energy generation improved Turkey’s energy security.

Research limitations/implications

This study identifies the energy security’s drivers in Turkey with a focus on industrialization and financialization. Nonetheless, further research is needed on other emerging economies with high energy insecurity levels, and a disaggregated approach can be followed to examine how various industrial sectors impact energy security.

Practical implications

To combat energy insecurity, quantifiable, innovative and energy-efficient goals should be set for Turkey’s industry sector. Additionally, to achieve these goals, financial opportunities should be provided by reforming the financial sector. This reformative approach can also curb financialization’s negative effect on Turkey’s energy security.

Social implications

Deindustrialization is not a solution to Turkey’s energy insecurity. Also, unless necessary actions are taken, industrialization, financialization and uncontrolled urbanization may continue to threaten Turkey’s energy security. Finally, promoting alternative energy generation seems to be a viable long-run solution to energy insecurity.

Originality/value

Although a significant number of studies investigated industrialization’s and financialization’s impacts on energy demand or environmental damage, only a few studies examined their impacts on energy insecurity. Similar to other developing nations, as Turkey is facing chronic energy security problems, the author believes that the analysis provides important policy insights regarding energy (in)security’s drivers. By differentiating the impacts of industrialization and deindustrialization, this study also shows that deindustrialization may not be a proper solution to deal with energy insecurity.

Abstract

Purpose

The purpose of this paper is to investigate the impact of financial development, economic growth and energy consumption on environment degradation for Indian economy by using the time series data for the period 1971-2011.

Design/methodology/approach

The stationary properties of the variables are checked by ADF, DF-GLS, PP and Ng-Perron unit root tests. The long-run relationship is examined by implementing the Autoregressive Distributed Lag bounds testing approach to co-integration and error correction method (ECM) is applied to examine the short-run dynamics. The direction of the causality is checked by VECM framework and variance decomposition is used to predict exogenous shocks of the variables.

Findings

The empirical evidence confirms the existence of long-run relationship among the variables. Financial development appears to increase environmental degradation in India. The main contributors to environmental degradation are: economic growth, energy consumption financial development and urbanization. The results also lend support to the existence of environmental Kuznets curves for Indian economy.

Research limitations/implications

The present study suggests that environmental degradation can be reduced at the cost of economic growth or energy efficient technologies should be encouraged to enhance the domestic product with the help of financial sector by improving environmental friendly technologies from advanced economies.

Originality/value

This paper proposes to make a contribution to the existing literature through examining the relationship between financial development and environmental degradation in Indian economy during 1971-2011 by employing modern econometric techniques.

Abstract

Purpose

This research investigates the threshold effects of the interplay between finance, development and carbon emissions across 97 countries, including 50 low-income and 47 high-income countries, during the period from 1991 to 2019.

Design/methodology/approach

Employing various econometric modeling techniques such as dynamic linear regression, dynamic panel threshold regression and in/out of sample splitting, this study analyzes the data obtained from the World Bank's world development indicators.

Findings

The results indicate that low-income countries require a minimum financial development threshold of 0.354 to effectively reduce carbon emissions. Conversely, high-income countries require a higher financial development threshold of 0.662 to mitigate finance-induced carbon emissions. These findings validate the presence of a finance-led Environmental Kuznet Curve (EKC). Furthermore, the study highlights those high-income countries exhibit greater environmental concern compared to their low-income counterparts. Additionally, a minimum GDP per capita of US$ 10,067 is necessary to facilitate economic development and subsequently reduce carbon emissions. Once GDP per capita surpasses this threshold, a rise in economic development by a certain percentage could lead to a 0.96% reduction in carbon emissions across all income levels.

Originality/value

This study provides a novel contribution by estimating practical financial and economic thresholds essential for reducing carbon emissions within countries at varying levels of development.

Abstract

Purpose

The purpose of this study is to validate the impact of economic and financial development along with energy consumption on environmental degradation using dynamic panel data models for the period 1980-2010. The study uses three sub-panels constructed on the basis of income level to make panel data analysis more meaningful.

Design/methodology/approach

Larsson et al. panel cointegration technique, fully modified ordinary least squares and vector error correction model causality analysis are applied for empirical estimation.

Findings

Main empirical findings demonstrate that financial development reduces environmental degradation in the high-income panel and increases environmental degradation in the middle- and low-income panels. Hypothesis of the environmental Kuznets curve is accepted in all income panels. Granger causality results show the evidence of bidirectional causality between financial development and CO2 emission in the high-income panel, and unidirectional causality from financial development to CO2 emission in the middle- and low-income panels.

Originality/value

In empirical literature, only a few studies explain the effect of financial development on environment. The present study is an effort to fill this gap by exploring the effect of economic and financial development on environmental degradation.

Abstract

Purpose

This paper investigates the (a)symmetric effects of financial development in the presence of economic growth, energy consumption, urbanization and foreign direct investment on environmental quality of South Africa between 1980 and 2017.

Design/methodology/approach

A robust measure of financial development is generated using banking institutions and non-banking institutions market-based financial development indicators, while environmental quality is measured using carbon footprint, non-carbon footprint and ecological footprint. The objectives of the study are captured using linear and non-linear autoregressive distributed lag.

Findings

The result from the symmetric analysis suggests that financial development stimulates carbon footprint and ecological footprint in the short run; however, financial development abates non-carbon footprint. In the long run, financial development has a significant negative effect on carbon footprint and ecological footprint. However, the asymmetric analysis established strong asymmetric effect in the short run, while no asymmetric effect is found in the long run. The short run asymmetric analysis reveals that positive shock in financial development increases carbon footprint and ecological footprint; however, positive changes in financial development reduce non-carbon footprint. Negative shocks in financial development, on the other hand, have a positive impact carbon footprint, non-carbon footprint and ecological footprint.

Practical implications

The study's outcome implies that the concept of “more finance, more growth” could also be applied to “more finance, better environment” in South Africa. The study offers vital policy suggestions for the realization of sustainable development in South Africa.

Originality/value

This empiric adds to the body of knowledge on the influence of financial development on various components of environmental quality (carbon footprint, non-carbon footprint and ecological footprint) in South Africa.

Abstract

Purpose

This study aimed to explore the effects of the satisfaction of employees' need for autonomy, relatedness and competence on their voice behavior through the mediation of self-efficacy for voice and perceived risk for voice.

Design/methodology/approach

The theoretical model is tested using survey data collected from 209 employees of information technology (IT) firms located in five major cities in China.

Findings

The study found that satisfaction of employees' need for autonomy, relatedness and competence facilitated their self-efficacy for voice and inhibited perceived risk for voice. Self-efficacy for voice was positively related to voice, whereas perceived risk for voice was negatively related to it. Perceived risk for voice hampered self-efficacy for voice.

Practical implications

The findings indicate that organizations can boost employees' voice behavior by making them feel that they have autonomy in their work, by helping them maintain good relationships with others in the workplace and by enabling their competence in accomplishing their job.

Originality/value

This study highlights that satisfying employees' psychological needs plays a pivotal role in facilitating their voice behavior. The authors provide new insights into the relationship between need satisfaction and voice behavior and into the mediating roles of self-efficacy for voice and perceived risk for voice.

Abstract

Purpose

The purpose of this study is to examine the relationship between pollutant emissions, financial development and IFRS in developed and developing countries between 1998 and 2022.

Design/methodology/approach

Data were obtained from World Development Indicators and World Governance Indicators of the World Bank.

Findings

Using FGLS and GMM estimators, the results provide evidence that financial development has a significant positive impact on a variety of pollutant emissions. However, this positive impact is moderated by IFRS for the overall sample and country income groups.

Practical implications

Governments and regulatory organizations should support companies’ investments in clean energy and technologies to slow down environmental degradation. Tax credits and subsidies may be helpful to achieve this goal. Also, governments may encourage companies to cooperate with universities and research institutions to develop environment-friendly production and distribution methods to reduce pollution. Although stakeholders may obtain information about environmental issues in financial statements that are prepared in accordance with IFRS, there is a need for standardization of their contents.

Social implications

Greenhouse gases are major contributors to climate change and global warming. In addition to private costs borne by producers, the production and consumption of products have social costs arising from pollution that affects air, water, and soil. Pollution adversely affects people's physiological and psychological health, which decreases labor productivity, thereby leading to a decrease in economic growth.

Originality/value

According to the author’s knowledge, this is the first study that examines the impact of IFRS on the relationship between financial development and pollutant emissions.

Abstract

Purpose

The purpose of this paper is to explore how social value orientation and domain knowledge affect cooperation levels and transcription quality in crowdsourced manuscript transcription, and contribute to the recruitment of participants in such projects in practice.

Design/methodology/approach

The authors conducted a quasi-experiment using Transcribe-Sheng, which is a well-known crowdsourced manuscript transcription project in China, to investigate the influences of social value orientation and domain knowledge. The experiment lasted one month and involved 60 participants. ANOVA was used to test the research hypotheses. Moreover, inverviews and thematic analyses were conducted to analyze the qualitative data in order to provide additional insights.

Findings

The analysis confirmed that in crowdsourced manuscript transcription, social value orientation has a significant effect on participants’ cooperation level and transcription quality; domain knowledge has a significant effect on participants’ transcription quality, but not on their cooperation level. The results also reveal the interactive effect of social value orientation and domain knowledge on cooperation levels and quality of transcription. The analysis of the qualitative data illustrated the influences of social value orientation and domain knowledge on crowdsourced manuscript transcription in detail.

Originality/value

Researchers have paid little attention to the impacts of the psychological and cognitive factors on crowdsourced manuscript transcription. This study investigated the effect of social value orientation and the combined effect of social value orientation and domain knowledge in this context. The findings shed light on crowdsourcing transcription initiatives in the cultural heritage domain and can be used to facilitate participant selection in such projects.
