A systematic literature review on circular economy practices: challenges, opportunities and future trends

Purpose The circular economy (CE) is an evolving subject transitioning from conceptualization to empirical testing. Over the past decade, researchers have done an exhaustive study to understand the concept of CE and its realized values both financially and environmentally on organizations that have traditional business models based on linear consumption. For understanding the transitional phenomena completely, the paper aims to review the current and emerging research trends in CE to ascertain future direction. Design/methodology/approach The research was conducted on 91 articles published in the study area during the past decade (2016–2021) in renowned peer-reviewed journals. The criteria set to review literature are based on the following assortment: CE drivers, CE barriers, definitions by different authors, yearly distribution of the publication, research publisher and journals, google citation and methodology used in the selected research articles. Findings The study suggests that researchers from the selected years are keen to understand the transition and its critical factors by bringing forward frameworks and incorporating CE with digital technologies. The digital technology implied are Industrial Technology (IR) 4.0, Big Data, Internet of Things (IoT), Artificial Intelligence, Blockchain and Data Analytics to increase organizational and environmental performance. CE researchers need to use empirical testing in different sectors to understand and bring forward more improvised business models and practices according to the dynamics of the industry. Originality/value The literature review suggests gaps exist to integrate the micro, meso and macro levels to get CE implementation's system-wide benefits. The study has also identified that many CE frameworks available in the literature for implementation must be empirically tested to yield performance results.

Emerging Opportunities in Manufacturing Bulk Soft-Magnetic Alloys for Energy Applications: A Review

Soft-magnetic alloys exhibit exceptional functional properties that are beneficial for a variety of electromagnetic applications. These alloys are conventionally manufactured into sheet or bar forms using well-established insgot metallurgy practices that involve hot- and cold-working steps. However, recent developments in process metallurgy have unlocked opportunities to directly produce bulk soft-magnetic alloys with improved, and often tailorable, structure–property relationships that are unachievable conventionally. The emergence of unconventional manufacturing routes for soft-magnetic alloys is largely motivated by the need to improve the energy efficiency of electromagnetic devices. In this review, literature that details emerging manufacturing approaches for soft-magnetic alloys is overviewed. This review covers (1) severe plastic deformation, (2) recent advances in melt spinning, (3) powder-based methods, and (4) additive manufacturing. These methods are discussed in comparison with conventional rolling and bar processing. Perspectives and recommended future research directions are also discussed.

The Gestational Effects of Maternal Appetite Axis Molecules on Fetal Growth, Metabolism and Long-Term Metabolic Health: A Systematic Review

Increased maternal food intake is considered a normal pregnancy adjustment. However, the overavailability of nutrients may lead to dysregulated fetal development and increased adiposity, with long-lasting effects on offspring in later life. Several gut-hormone molecules regulate maternal appetite, with both their orexigenic and anorectic effects being in a state of sensitive equilibrium. The aim of this manuscript is to systematically review literature on the effects of maternal gut-hormone molecules on fetal growth and metabolism, birth weight and the later metabolic health of offspring. Maternal serum ghrelin, leptin, IGF-1 and GLP-1 appear to influence fetal growth; however, a lack of consistent and strong correlations of maternal appetite axis hormones with birth weight and the concomitant correlation with fetal and birth waist circumference may suggest that these molecules primarily mediate fetal energy deposition mechanisms, preparing the fetus for survival after birth. Dysregulated intrauterine environments seem to have detrimental, sex-dependent effects on fetal energy stores, affecting not only fetal growth, fat mass deposition and birth weight, but also future metabolic and endocrine wellbeing of offspring.

An Exploratory Literature Study into Digital Transformation and Leadership: Toward Future-Proof Middle Managers

This study aimed to obtain insight into the influence digital transformation has on future leadership behaviors and management. Up to now, most literature solely focuses on the need for strong strategic leadership to build and lead the transformation. This study was directed at future leadership behaviors and skills needed during and after digital transformation of management below senior level. An exploratory approach to review literature on digital transformation and leadership was used, inspired by the PRISMA protocol. Our findings show that digital transformation is a disruptive process that impacts the whole organization and results in new forms of working. This calls for altro-centric leadership, an other-centered leadership style. Specifically, soft skills such as empathy, humility, integrity and compassion are becoming increasingly important, as is understanding the power of digital technology. The emergence of artificial intelligence offers interesting opportunities. It could be used to handle quantifiable managerial tasks and evaluate the quantifiable part of performance, while managers focus on the soft skills side of management such as coaching, motivating and empowering employees. This study demonstrates the necessity to redefine leadership requirements in an increasingly digitalized world.

When community change theory meets practice: Exploring some of the challenges to information sharing networks for community change

Networked community change (NCC) efforts focus on building and supporting networks of stakeholders in communities to address complex problems, with a particular focus on tie formation among stakeholders and organizer facilitation of an information-sharing network (Lawlor & Neal, 2016). NCC approaches include, for example, systemic action research (Burns, 2007), Collective Impact (Kania & Kramer, 2011), and network action research (Foth, 2006) and can be understood as community-level interventions supporting change (Bess, 2015). Previous research demonstrates the promising nature of NCC efforts under ideal circumstances for efficient information sharing in community change efforts. However, these efforts frequently operate in non-ideal conditions, needing to adapt to a variety of community challenges. This article extends the agent-based simulation model presented in Lawlor and Neal (2016) to reflect the challenges that arise when stakeholders implement these approaches to community change and identify how they can impact information-sharing networks. First, we review literature to establish common challenges that arise in these efforts. Second, we employ the Lawlor and Neal (2016) model to examine these challenges and report on the resulting structure of the information-sharing networks that emerge from implementing them in the simulation model. We conclude with implications of common networked community change challenges on network formation and future directions for addressing these real-world challenges as communities work on complex problems.

Siting of Healthcare Care Facilities Based on the Purpose of Their Operation, Demographic Changes, Environmental Characteristics, and the Impact on Public Health

A contemporary approach to the spatial design of healthcare care facilities faces numerous challenges at the crossroads of multidisciplinary topics of architecture and urbanism, healthcare, security, and organisational sciences. Due to the unique combination of uses, users and architectural expression, they are defined as urban nodes. With their inclusion, architects facilitate a better placing of healthcare facilities, indirectly improving human health. The purpose of the article is to seek guidelines for the siting of healthcare facilities to provide suitable and equal healthcare to different social structures, and for the optimal and fair spatial distribution of healthcare services. The descriptive method was used to review literature on the siting of healthcare facilities based on the purpose of their operation, demographic changes, environmental characteristics, and the impact on public health. This method was selected as it facilitates data acquisition from various sources and a comprehensive understanding of the topic discussed. The results of the research show how important the impact of the healthcare care facilities siting on human health and the wider social significance of the topic discussed is. The findings may provide guidelines and proposals for future spatial decisions.

Lean and agile metrics. Literature review and framework for measuring leagile supply chain

PurposeThe aim of this paper is to review metrics and develop a framework for measuring leagile supply chain. Metrics that are applicable in the lean, agile and leagile strategies are identified in the literature and are then combined into a framework that can reflect both agile and lean strategies – the leagile supply strategy.Design/methodology/approachThis work is based on the systematic literature review. Literature was collected, then lean and agile metrics were extracted, analysed, counted and grouped into the framework. Findings are compared against literature on leagile supply chain.FindingsFindings indicate that there are sets of metrics specific to lean strategy, such as are process-focused, cost, productivity, inventory and delivery-based metrics, and specific to agile such as flexibility, responsiveness, information sharing and cooperation. There are also metrics common for both strategies; they are related to time, quality and customer satisfaction. Lean measures are tangible and focused on internal processes and products, while agile measures are targeted at external environment.Practical implicationsThe framework could be used by practitioners as a starting point for performance system design.Originality/valueThere is a need to stop looking at lean and agile as separate and distinct supply strategies. Results of this research indicate that lean and agile are interlinked, both are focusing on customer satisfaction and quality. Applying a proposed set of metrics enables to design supply chain measurement system that reflects both strategies to measure leagile supply chain. The framework could be used by practitioners as a starting point for performance system design.
