The proposal is to answer the following question: based on previous studies, which are the new paths and challenges related to the circular economy (CE) and Industry 4.0 (I4.0)? To answer this question, the research objective is to analyze studies approaching the interface between CE and I4.0.

A systematic literature review (SLR) was conducted on previously published studies pertaining to Scopus and Web of Science bases, and 63 articles were found.

The authors present five new paths and challenges amid the relationship between CE and I4.0: applying those technologies to clean production, using blockchain and big data in the circular supply chain, raising additive manufacturing impact on the CE, seek for a better understanding on how I4.0 technologies can properly support the CE in the stakeholders' view and discerning the factors for implementing those theoretical fields onto supply chains.

Previous studies' sample basis is still recent, lacking research depth. Search strings might have minimized the number of selected studies: there could be a bigger sample.

Practical contributions of this study lay on the applicability of the raised propositions into several sectors' industries.

The authors suggest a transition agenda towards CE, using I4.0 technologies for operational, tactical and strategic personnel within organizations, as well as potential utilization strategies in specific study fields, like supply chain management and product manufacturing per se.

The study presents new paths and challenges amid technologies pertaining to I4.0 and its interfaces with the CE. In the result presentation and analysis, the existing interfaces are described.

This paper aims to investigate the reciprocal nonlinear relationship between corporate social responsibility (CSR) and firm performance (FP).

The authors used a sample of 814 European firms over the period 2008–2017. The Panel Smooth Transition Regression (PSTR) model was performed as an econometric approach.

Firstly, results show a threshold effect in the CSR–FP relationships within the two directions. More specifically, the authors found that firms are more likely to engage in CSR by surpassing a threshold of 1.231% for return on assets (ROA) and 0.821% for Tobin’s Q ratio. Secondly, the authors also found that the impact of CSR on FP is positive and significant only if the environment, social and governance score surpasses the threshold of 56.780% when the dependent variable is ROA and 41.02% when Tobin’s Q ratio measures performance.

A significant part of the literature supports the linear relationship between CSR and FP from the unique direction (CSR → FP). This study comes to fill this gap by assessing the possible nonlinear relationship. In addition, this nonlinear relationship is tested under the two directions. Therefore, defining the threshold of FP that allows companies to engage in CSR, on the one hand, and the threshold of engagement in CSR that improves FP, on the other hand, could be an exciting topic.

To get the full benefit from CSR effects, firms should be with better financial performance to be socially responsible.

To the best of our knowledge, few studies have explored the nonlinear relationship between CSR and FP. In addition, this study raises the question of whether this relation is causal. The authors assess the two nonlinear relationships between CSR ? FP and FP ? CSR by determining the optimal thresholds.

本文旨在探究企業社會責任 (以下簡稱企社責) 與公司業績之間的相互非線 性關係。

研究所採用的樣本為814間歐洲公司, 涵蓋期為2008年至2017年。研究人 員使用縱橫平滑轉換模型、作為經濟計量方法和工具去進行研究。

研究結果顯示、在有關的兩個方向內, 企社責與公司業績之間的關聯上是 存在著閾值效應的。更具體地說, 研究人員發現, 若企業的資產報酬率超過1.231%的 水平, 以及托賓的Q比率 (Tobin’s Q Ratio) 0.821%的水平的話, 它們會更願意承擔企 社責。其次, 研究結果亦顯示, 企社責對企業的業績會產生積極的影響; 另外, 只有 當資產報酬率是因變數、而環境、社會和公司治理的分數 (ESGS) 超過56.780%, 以 及當托賓的Q比率用來測量績效、而數值為41.02%時, 企社責對企業的業績所產生的 影響會較為顯著。

過去的學術文獻、大部份都是以唯一的方向 (企社責 ->公司業績) 去確認 企社責與企業業績之間的線性關係。本研究評估了兩者之間可能存在的非線性關係; 而且, 這非線性關係是在有關的兩個方向下而進行測試的; 因此, 本研究一方面給可 讓公司以企社責的精神和理念去營運的企業業績的閾值下了定義; 另一方面, 又給參 與企社責為公司帶來業績的改善的閾值下了定義。這均為令人興奮的課題。

企業若想取得因參與企社責而帶來的完全好處, 它們必須擁有更佳 的財務績效、以能盡其社會責任。

盡我們所知, 探究企社責與企業業績之間的非線性關係的研究實在不 多; 而且, 本研究對這兩者的關係是否是因果關係提出了質疑; 就此, 我們藉著釐定 最佳的相對閾值、來評估企社責 ->企業業績與企業業績 ->企社責之間的兩個非線性的 關係。

In the course of worldwide COVID-19, the phenomenon of corporate social responsibility (CSR) gained more importance and publicity. Many organizations made a significant contribution in dealing with the crisis situation and even increased their spending on the welfare activities. This study aims to evaluate the attitude of community, especially young generation, towards the CSR undertaken by the organization during the pandemic period.

Descriptive research design has been employed using purposive sampling for data collection through a structured questionnaire. A sample of 550 was taken, and pilot survey was conducted among 100 respondents before administering it at full scale. A model has been proposed and tested by using structural equation modelling in AMOS.

The results of the study show that compulsory provisions of CSR have enhanced the trust of community and made the organizations more responsive towards philanthropic, legal, ethical and economic responsibility. The respondents were found to be aware about the welfare activities carried out by the organizations and developed a positive attitude towards them.

First, the study is limited to examining the attitude of community towards CSR, especially young generation. Second, it is difficult to say whether outcomes of this study can be generalized for such other potential global crisis. Third, the study is based on the Carroll’s “CSR Pyramid” framework when other such frameworks and approaches could be available to analyse the impact of COVID-19-related CSR initiatives. Last, this study has been conducted only in the state of Maharashtra, and results may not be applicable to other states as well other countries.

The findings of the study may help the organizations to plan their activities in line with the amendments made time to time. This shall also help the regulating agencies to monitor and catch the wrongdoers and take appropriate action. Findings of such studies, based on public opinion, can also help the governments to make further amendments, time to time, in related acts. It can also be said that with the involvement of public/society, more transparency can be brought in the functioning of the organizations, especially in the context of CSR.

Earlier, most of the organizations were falsely recording the CSR expenditure in their balance sheets without actually spending it, but the amendment in act has made it compulsory for the organizations to follow it honestly. The pandemic period gave an opportunity to the society to evaluate the organizations on these parameters and to make their opinion about them in real time. Therefore, it is concluded that pandemic has created awareness in the society and significantly influenced their attitude about CSR activities. This shall also help the organizations feel a pressure in future while planning and implementing the activities under CSR.

The results of the study show contribution of the corporate towards social welfare during pandemic. The results would help the policymakers to monitor the execution of practices more closely and organizations to execute their strategies in a more effective manner.

This study aims to facilitate consistency of information in building information modelling (BIM) and address the current BIM gaps through the perspectives of the productization concept and product structure (PS).

The study follows a conceptual research approach in conjunction with a single case study. First, the previous studies on BIM implementation, productization and PS are reviewed. Further, a case study is used to analyse the current state of productization in the construction sector and develop a functional PS for construction.

A Part-Phase-Elements Matrix is proposed as a construction-specific PS to facilitate consistency in information and to enhance BIM. The proposed matrix provides new avenues to facilitate consistent information exchange through the interconnection between conceptual PS and standard building objects library, and encourage collaborative communication between stakeholders.

This study explores the core of the productization concept and PS as means to facilitate consistency of information and thus address the current gaps in BIM. This as building projects progressively move towards systematic modular and prefabricated construction where the flow of reliable information about product and construction offerings becomes increasingly important.

This paper aims to provide a typical example of accounting for the carbon dioxide equivalent (CO₂e) in underdeveloped cities, especially for the Poyang Lake area in China. The accounting can increase public understanding and trust in climate mitigation strategies by showing more detailed data.

The paper uses the “Global Protocol for Community-scale greenhouse gas emission inventories (GPC)” method, a worldwide comparable framework for calculating urban CO₂e emission (CE). The empirical case is an underdeveloped city, Nanchang, in China.

The results show the total CE of Nanchang, containing the electricity CE of Scope 2, grew rapidly from 12.49 Mt in 1994 to 55.00 Mt in 2014, with the only recession caused by the global financial crisis in 2008. The biggest three contributors were industrial energy consumption, transportation and industrial processes, which contributed 44.71-72.06, 4.10-25.07 and 9.07-22.28 per cent, respectively, to the total CE. Almost always, more than 74.41 per cent of Nanchang’s CE was related to coal. When considering only the CEs from coal, oil and gas, these CEs per unit area of Nanchang were always greater than those of China and the world. Similarly, these CEs per gross domestic product of Nanchang were always bigger than those of the world. Thus, based on these conclusions, some specific countermeasures were recommended.

This paper argues that the CO₂e accounting of underdeveloped cities by using the GPC framework should be promoted when designing climate mitigation policies. They can provide more scientific data to justify related countermeasures.

This study aims to examine whether sport companies that promote gender equality through femvertising, an advertising trend that empowers women and confronts gender stereotypes, actually support women’s rights with institutionalized approaches to challenge gender issues. Some sport brands even have won awards for their femvertising efforts, however, not all of them have modified their policies and programs to support gender equality. Sport femvertising can be a new area for CSR-washing and this study investigated this potential.

Utilizing a content analysis, this study compared sport brands' (award-winning vs non-award-winning) level of engagement in internal and external CSR activities regarding gender equality. Sport brands’ CSR attempts and number of women in leadership positions were analyzed through companies’ CSR reports, annual reports and websites.

Only few differences between two groups (award-winning vs non-award-winning) of sport brands were observed regarding their gender equality CSR engagement. In some cases, non-award-winning sport brands had a greater percentage of women in leadership and practiced more internal gender equality CSR.

This paper provides valuable information about the potential of femvertising as an advertisement, as well as CSR strategy. Results of this study broaden our understanding of how sport companies embraced this advertising/CSR technique and the repercussions. Findings provide guidance for sport marketers who seek to improve their brand image through femvertising.

This study aims to bridge a gap in literature by exploring the impact of art and culture projects on primary internal stakeholders (i.e. employees), focusing on the micro-foundations of corporate social responsibility (CSR).

The analysis uses a qualitative approach, using a single-case study and semi-structured interviews. The single-case study focuses on art and culture projects developed by companies participating in the public contest promoted by Parma City of Culture 2020. The analysis relies on the information gathered from interviews with the employees who were involved in the projects of seven of the winning companies.

The results suggest that employees positively assess their participation in CSR activities based on art and culture projects. Specifically, through their direct involvement in the competition employees manage to experience meaningfulness and they attribute intrinsic motives to these types of activities.

This study analyses the effectiveness of a publicly endorsed CSR initiative oriented towards internal social enhancement based on art and culture projects, leveraging the unique case of Parma City of Culture 2020. The findings might be beneficial to both companies and regulators aiming to achieve internal social enhancement. This study contributes to existing literature on the social dimension of CSR by emphasising the key role of art and culture projects in the organisational context and by opening new avenues for future research.

This study examines the osteoconductive and healing capabilities of locally implanted synthetic hydroxyapatite (sHAp) derived from eggshells in the central incisor sockets of rats.

Toxicity experiments were conducted in vitro and in vivo, to testify the safety dosage of sHAp. Around 24 mature male Sprague–Dawley (SD) rats had their upper central incisors extracted. The rats were placed into three groups of eight rats each: Group 1: the sockets of extracted central incisors were left unfilled (control), Group 2: filled up with commercially available hydroxyapatite (HAp) and Group 3: implanted with sHAp locally retrieved from eggshells. After extraction, four rats from each group were sacrificed at 2nd and 4th weeks. Maxillary tissue sections were obtained and stained with hematoxylin and eosin (H&E) and Masson’s trichome (MT) staining. Anti-osteocalcin (OCN) and proliferating cell nuclear antigen (PCNA) were used primary antibodies for immunohistochemistry (IHC) special labeling.

The results showed that the locally implanted sHAp was non-toxic and safe in cell lines (human osteoblast and fibroblast) and animals. Histological analysis of H&E, MT and IHC showed that the sockets treated with locally implanted sHAp from eggshells were filled with new bone tissue of comparable thickness to other groups.

This unique technique uses locally implanted eggshell-derived sHAp with osteoconductive characteristics. In an in vivo model, sHAps increased OCN and PCNA expression to improve bone repair.

With the increasing acclaim of Wireless Sensor Networks and its diverse applications, research has been directed into optimising and prolonging the network lifetime. Energy efficiency has been a critical factor due to the energy resource impediment of batteries in sensor nodes. The proposed routing algorithm therefore aims at extending lifetime of sensors by enhancing load distribution in the network. The scheme is based on the chain-based routing technique of the PEGASIS (Power Energy GAthering in Sensor Information Systems) protocol and uses Ant Colony Optimisation to obtain the optimal chain. The contribution of the proposed work is the integration of the clustering method to PEGASIS with Ant Colony Optimisation to reduce redundancy of data, neighbour nodes distance and transmission delay associated with long links, and the employment an appropriate cluster head selection method. Simulation results indicates proposed method’s superiority in terms of residual energy along with considerable improvement regarding network lifetime, and significant reduction in delay when compared with existing PEGASIS protocol and optimised PEG-ACO chain respectively.
