The Relationship

Purpose The purpose of this study aims to analyze the dynamic behavior of the relationship between atmospheric carbon emissions and the Organisation for Economic Co-operation and Development (OECD) industrial production index (IPI) in the short and long term by applying multifractal techniques. Design/methodology/approach Multifractal de-trended cross-correlation technique is used for this analysis based on the relevant literature. In addition, it is the most widely used approach to estimate multifractality because it generates robust empirical results against non-stationarities in the time series. Findings It is revealed that industrial production causes long and short term environmental costs. The OECD IPI and atmospheric carbon emissions were found to have a strong correlation between the time domain. However, this relationship does not mostly take into account the frequency-based correlations with the tail effects caused by shocks that are effective on the economy. In this study, the long-term dependence of the relationship between the OECD IPI and atmospheric carbon emissions differs from the correlation obtained by linear methods, as the analysis is based on the frequency. The major finding is that the Hurst coefficient is in the range 0.40-0.75 indicating. Research limitations/implications In this study, the local singular behavior of the time-series is analyzed to test for the multifractality characteristics of the series. In this context, the scaling exponents and the singularity spectrum are obtained to determine the origins of this multifractality. The multifractal time series are defined as the set of points with a given singularity exponent a where this exponent a is illustrated as a fractal with fractal dimension f(α). Therefore, the multifractality term indicates the existence of fluctuations, which are non-uniform and more importantly, their relative frequencies are also scale-dependent. Practical implications The results provide information based on the fluctuation in IPI, which determines the main conjuncture of the economy. An optimal strategy for shaping the consequences of climate change resulting from industrial production activities will not only need to be quite comprehensive and global in scale but also policies will need to be applicable to the national and local conditions of the given nation and adaptable to the needs of the country. Social implications The results provide information for the analysis of the environmental cost of climate change depending on the magnitude of the impact on the total supply. In addition to environmental problems, climate change leads to economic problems, and hence, policy instruments are introduced to fight against the adverse effects of it. Originality/value This study may be of practical and technical importance in regional climate change forecasting, extreme carbon emission regulations and industrial production resource management in the world economy. Hence, the major contribution of this study is to introduce an approach to sustainability for the analysis of the environmental cost of growth in the supply side economy.

Subject Carbon transitions. Significance The EU in May failed to reach an agreement on how to achieve a long-term strategy on reducing carbon emissions. One of the issues underlying the persistent differences among member states was the question of how to achieve a ‘just transition’. This is becoming an increasingly significant element of national and international debates on tackling climate change. Impacts The International Labour Organisation believes a transition limiting heat rises to 2 degrees by 2030 would create 24 million jobs globally. Global coal production may stabilise as reductions in developed economies are offset by increases in Asia. The UK Treasury estimates that achieving carbon neutrality by 2050 will cost 1 trillion pounds (1.26 trillion dollars).

Purpose The purpose of this study is to investigate the effect of the Trans-Anatolian Natural Gas Pipeline Project (TANAP) on industrial production in Turkey. The TANAP is a project which ensures the security of the country’s natural gas supply and encourages a decrease in energy prices. So, this study investigates TANAP’s efforts to decrease gas prices, as well as the effects of gas prices on industrial production. Design/methodology/approach The data include gas prices and industrial production index series. Gas prices are approached for industrial users (nonresidential) in Turkey and industrial production index series have been discussed for whole industries. The Johansen cointegration method has been used to analyze the data, spanning the period from 2005M01 to 2015M11. Findings Results indicate that the decrease in the energy prices has a positive effect on the industrial production index, which is accepted as a basic sign of economic growth. Accordingly, it has been proved that gas priced had a significant effect on industrial production in Turkish economy during the respective periods. Research limitations/implications This study has supported the argument that TANAP helps to decrease gas prices in Turkey. It can be said that a decrease in gas price is expected to have positive effect on industrial production in the long-term. Originality/value The present study shows that projects such as TANAP can help gas importing countries like Turkey to decrease gas prices and increase industrial production. In this context, this study supports projects that decreasing gas prices for energy importing countries in the long term.

AbstractPhenology serves as a major indicator of ongoing climate change. Long-term phenological observations are critically important for tracking and communicating these changes. The phenological observation network across Germany is operated by the National Meteorological Service with a major contribution from volunteering activities. However, the number of observers has strongly decreased for the last decades, possibly resulting in increasing uncertainties when extracting reliable phenological information from map interpolation. We studied uncertainties in interpolated maps from decreasing phenological records, by comparing long-term trends based on grid-based interpolated and station-wise observed time series, as well as their correlations with temperature. Interpolated maps in spring were characterized by the largest spatial variabilities across Bavaria, Germany, with respective lowest interpolated uncertainties. Long-term phenological trends for both interpolations and observations exhibited mean advances of −0.2 to −0.3 days year−1 for spring and summer, while late autumn and winter showed a delay of around 0.1 days year−1. Throughout the year, temperature sensitivities were consistently stronger for interpolated time series than observations. Such a better representation of regional phenology by interpolation was equally supported by satellite-derived phenological indices. Nevertheless, simulation of observer numbers indicated that a decline to less than 40% leads to a strong decrease in interpolation accuracy. To better understand the risk of declining phenological observations and to motivate volunteer observers, a Shiny app is proposed to visualize spatial and temporal phenological patterns across Bavaria and their links to climate change–induced temperature changes.

Purpose The purpose of this paper is to examine the relationships between supplier development practices (SDPs) and supplier-buyer relationship practices from the supplier’s perspective (SBRSP), and seek to understand how specific SDPs may impact a buyer’s operational performance as well as supplier-buyer relationship practices. Design/methodology/approach The authors conducted a survey of 512 respondents from the different manufacturing firms in India and applied structural equation modelling to test a structural model that proposes the impacts of various efforts of SDPs on a buyer’s performance as well as SBRSP. Findings The study concludes that SDPs and SBRSP together improve the relationship between a buyer and supplier, and this improved relationship leads to competitive advantages (CAs) followed by profitability. Results indicate that supplier perspective of buyer-supplier relationship can be improved under the condition of SDPs and SBRSP together. SDPs are driven by productive measure and competitive pressure, whereas customer uncertainty is found to be statistically insignificant. Research limitations/implications The study was carried out in North Maharashtra Industrial Zone of India, where the auto sector and machine/components manufacturing firms have been established for a considerable period of time. Results of the study are limited to manufacturing organizations predominantly focussing on the automobile sector and machine/components manufacturing firms. Practical implications This study provides significant insights into the specific impact of various SDPs and SBRSP for both academics and practitioners. SDPs along with SBRSP practices lead to improvement in the relationship leading to CAs. SBRSP suggests that trust, long-term commitments and the supplier’s perspective are important practices for relationship improvement. Originality/value The current study attempts to identify what are the success factors for the supplier-buyer relationship from the supplier’s perspective and SDPs and how the supplier-buyer relationship can be improved under the condition of SDPs and SBRSP. Hence, the aim is to develop a more thorough understanding of the outcomes of a supplier-buyer relationship improvement from both buyer’s and supplier’s perspective, under the conditions of supplier development to achieve CAs leading to profitability. Furthermore, the study analyses the effect of the improved supplier-buyer relationship for achieving CAs leading to profitability.

Abstract The importance of estuarine seagrass beds as nurseries for juvenile fish has become a universal paradigm, especially for estuaries that are as important as the Chesapeake Bay. Yet, scientific tests of this hypothesis were equivocal depending on species, location, and metrics. Moreover, seagrasses themselves are under threat and one-third of seagrasses have disappeared worldwide with 65% of their losses occurring in estuaries. Although there have been extensive studies of seagrasses in the Chesapeake Bay, surprisingly few studies have quantified the relationship between seagrass as nurseries for finfish in the Bay. Of the few studies that have directly evaluated the use of seagrass nurseries, most have concentrated on single species or were of short duration. Few landscape-level or long-term studies have examined this relationship in the Bay or explored the potential effect of climate change. This review paper summarizes the seagrass habitat value as nurseries and presents recent juvenile fish studies that address the dearth of research at the long term and landscape level with an emphasis on the Chesapeake Bay. An important conclusion upon the review of these studies is that predicting the effects of climate change on fishery production remains uncertain.

Abstract We examine the relationship between financial inclusion and carbon emissions. For this purpose, we develop a composite indicator of financial inclusion based on a broad set of attributes through principal component analysis (PCA) for 26 countries in the Asia region. Our robust panel regression analysis reveals a significant positive long-term impact of financial inclusion on carbon emissions. The pairwise causality test reveals unidirectional long-term causality running from financial inclusion to carbon emissions. The study suggests that policy makers may design policies that integrate accessible financial systems into climate change adaptation strategies in order to neutralize the side effect of financial inclusion deteriorating environmental quality and inclusive sustainable economic growth.

Purpose This study aims to address the absence of a thorough understanding of commitment in tourism public-private partnerships (PPP) by exploring antecedents of PPP commitment and their underpinning relationships in regard to the destination management system (DMS). Design/methodology/approach An empirical investigation of the case of the Egyptian DMS, a PPP which was forsaken by the government partner and which subsequently failed. Qualitative and quantitative approaches are used for a comprehensive overview of the researched phenomena pertaining to external and internal stakeholders. Findings The results indicated that stakeholder management, relational capital, perceived benefits and stakeholder capabilities could influence intentions to commit to a tourism PPP project. Also, the latter three factors were found to mediate the relationship between stakeholder management and long-term PPP commitment. The results also shed light on the important aspects of non-contractual, interpersonal relationships between internal and external PPP stakeholders. Originality/value This research pioneers inquiries on the commitment of Tourism PPP/DMS projects and its possible drivers in a non-Western context. Also, this study contributes to knowledge by exploring the relationship within and between internal (partners) and external (e.g. local service providers) stakeholder groups and provided evidence on the crucial role of both on long-term PPP commitment and success. The current study has a few significant contributions to the PPP literature regarding the commitment and success of PPP in the complicated environments in which tourism PPP projects are operated. Moreover, this study offers essential information and practices for improving partner relationships with external stakeholders.

Purpose – The purpose of this paper is to analyse the relationship between the environmental management of purchases and firm performance. The authors examine the moderating role played by two variables: the establishment of long-term relationships with suppliers and the strategic integration of the purchasing function. Design/methodology/approach – The authors conduct an empirical study on a sample of 100 Portuguese firms. Findings – Evidence reveals that green purchasing management improves the performance of the purchasing function, although the impact is greater when the organisation forges lasting alliances with its suppliers. Originality/value – This paper contributes to the study of the consequences of introducing environmental practices into the purchasing function, especially with regards to the formation of a panel of sustainable suppliers. Specifically, this research provides evidence to show that the implementation of those practices has positive impacts on the operating performance of the purchasing function and that the said effect is greater when a firm establishes long-term relationships with its suppliers.

Purpose The purpose of this paper is to examine the relationship between levels of human capital and financial performance of firms that use two distinct human resource management (HRM) strategies. Design/methodology/approach A survey of 128 HRM managers was conducted to assess differences in human capital between firms using different HRM strategies. A multiple regression analysis was used to investigate the relationship between firms’ human capital and financial performance. Findings The results show that companies employing a make-organic strategy have a higher level of human capital than companies employing a buy-bureaucratic strategy. There was no relationship between the level of human capital and long term financial performance of firms with both make-organic and buy-bureaucratic strategies. Research limitations/implications This research contributes toward understanding the effect of HRM strategy and facilitates an optimal strategy choice depending on the organization. However, this study did not consider the lead time between changes in human capital and the effect on financial performance. Practical implications The research encourages firm managers to understand the value of human capital, preparing them for changes in the future. Originality/value This study is among the first to investigate the relationship between human capital and financial performance considering different HRM strategies.
