Depth Analysis

PurposeManaging stakeholders' reciprocal interdependencies is always a challenging issue. Stakeholders need to find out different ways to communicate information and coordinate material flows during the supply chain processes. Many recent studies have advanced construction supply chain coordination from multiple perspectives. However, the field still lacks a comprehensive analysis to summarize existing research, to explicitly identify all the possible enablers for coordination and to investigate how the enablers can be carried out at the supply chain interfaces. To fill the gap, this study aims to conduct a systematic review in order to examine the relevant literature.Design/methodology/approachA systematic literature review process was conducted to identify and synthesize relevant publications (published in the past 20 years) concerning the coordination of construction supply chain functions. These publications were coded to link main research findings with specific enabler categories. In addition, how these enablers can be used at the interfaces across supply chain processes was reviewed with an in-depth analysis of reciprocal communications between stakeholders at design-to-production, production-to-logistics and production-to-site-assembly phases.FindingsThe coordination enablers were classified into three categories: (1) contractual enablers (including subtopics on relational contracts and incentive models), (2) procedural enablers (including subtopics on multiagent knowledge sharing systems and the last planner system) and (3) technological enablers (including subtopics on linked databases for design coordination, design for manufacturing software platforms and automated monitoring technologies). It was found that interfacing different functions requires a certain level of integration of stakeholders for quick response and feedback processes. The integration of novel contractual forms with digital technologies, such as smart contracts, however, was not adequately addressed in the state of the art.Research limitations/implicationsThe scope of the systematic review is limited to the static analysis of selected publications. Longitudinal studies should be further included to sharpen the inductions of enablers considering organizational changes and process dynamics in construction projects.Practical implicationsDifferent enablers for coordination were summarized in a concise manner, which provides researchers and project stakeholders with a reinforced understanding of various ways to manage reciprocal interdependencies at different supply chain interfaces.Originality/valueThis study constitutes an important input for research on the construction supply chain by illuminating the thematic topic of coordination from inductively developed review processes, which included a holistic framing of the emerging coordination enablers and their use across supply chain functions. Consequently, it closes some identified knowledge gaps and offers additional insights to improve the supply chain performance of construction projects.

Purpose The purpose of this paper is to explore the popularity of Japanese lesson study (JLS) beyond Japan and the challenges this translation might pose. It notes that there is not a universally accepted definition of lesson study (LS) and seeks to identify the “critical components” of JLS through a review of the literature. It then uses a systematic literature review of recent studies of the implementation of LS with in-service teachers beyond Japan to analyse the models of LS used against these seven critical components in order to explore the degree of fidelity to the Japanese model. Design/methodology/approach A broad review of the literature on JLS available in the English language identifies seven “critical components”. A systematic literature review of 200 recent English language studies of the implementation of LS with in-service teachers beyond Japan is then carried out. Articles published between 2005 and 2015 are explored, including peer reviewed articles, scientific journals, book chapters and PhD dissertations. This systematic review enables an analysis of the models of LS used in studies from beyond Japan against the “seven critical components” of JLS. Findings The analysis shows that there is not an internationally shared understanding of Japanese lesson study (JLS) and that many of the missing components are those which distinguish LS as a research process, not simply a collaborative professional development approach. It also reveals that UK LS models seem particularly far from the Japanese model in those critical components which connect teachers’ knowledge and understanding within groups, to knowledge and understanding that exists beyond it. The study discusses whether these differences could be attributed to structural or cultural differences between Japan and other nations. Research limitations/implications The search for descriptions of the JLS is limited to articles available in the English language, which, therefore, represent a quite limited body of authority on the “critical components” of LS. The systematic review is similarly limited to English language articles, and there is a clear bias towards the USA, with the Far East and the UK making up the majority of the remaining studies. The study suggests that future research on LS beyond Japan should consider teachers’ attitudes towards the research elements of the process as well as their skills and confidence in carrying out research into practice. Practical implications The study strikes a note of caution for schools wishing to implement JLS as an approach to teacher professional development in the UK and beyond. Japan’s systemic approach has embedded LS experience and expertise into the education system, meaning a uniform approach to LS is much more likely. In addition, other systemic challenges may arise, for example, UK professional development time and resources is not designed with JLS in mind and may therefore require a significant reworking. Originality/value Whilst several systematic reviews of LS have explored its growth, geographical spread, impact and key features, this study provides a different perspective. It analyses whether and to what degree the “lesson study” models these studies describe align with the literature on JLS, and the implications of this for researchers and practitioners.

Retrobulbar Hemorrhage

Decreasing visual acuity secondary to orbital trauma may be caused by sudden space-occupying or expanding intraorbital lesions, including retrobulbar hemorrhage (RBH), herniation, or swelling. RBH must be diagnosed and treated immediately. This article addresses the efficacy of transcutaneous transseptal orbital decompression in a combination with a systematic review of the literature for a comparison of this method with existing treatment options. For this study the department's database was retrospectively screened for patients with acute RBH who were treated between 2009 and 2011 using the authors’ approach. Patients presenting with RBH were classified into RBH classes I to III according to three different clinical and radiological manifestations of acute RBH. The efficacy of transcutaneous transseptal orbital decompression was assessed by postoperative visual acuities. The literature review was performed by using the MEDLINE database. The time period for the study was between 2009 and 2011 during which 10 patients were diagnosed with suspected RBH and 9 were treated with the authors’ technique. Visual acuities were reconstituted or maintained in almost 86% of patients who were diagnosed and treated according to the authors approach and who survived initial trauma. It was concluded that transcutaneous transseptal orbital decompression provides an efficient and rapid approach for treating patients with acute RBH. By distinguishing three different manifestations of acute RBH, the authors present a diagnostic tool that may facilitate classification of RBH and determination of treatment options.

This paper presents a systematic literature review (SLR) about realistic simulators that can be applied in an educational robotics context. These simulators must include the simulation of actuators and sensors, the ability to simulate robots and their environment. During this systematic review of the literature, 559 articles were extracted from six different databases using the Population, Intervention, Comparison, Outcomes, Context (PICOC) method. After the selection process, 50 selected articles were included in this review. Several simulators were found and their features were also analyzed. As a result of this process, four realistic simulators were applied in the review’s referred context for two main reasons. The first reason is that these simulators have high fidelity in the robots’ visual modeling due to the 3D rendering engines and the second reason is because they apply physics engines, allowing the robot’s interaction with the environment.

The European Commission’s strategic long-term vision for 2050, “A Clean Planet for All”, identifies the bioeconomy and the circular economy as key strategic areas for achieving a climate-neutral economy. Focus is given to the sustainability of biomass and the circularity of materials. However, in order to facilitate the transition toward a sustainable bio-based circular economy and to unlock its potential, strong accompanying measures are required. These should be designed based on a systematic understanding of transition drivers and barriers. This paper, after providing a systematic review of transition research on the circular bioeconomy, focuses on the identification and classification of transition barriers, clustering them into relevant categories. Moreover, it provides a comparison of the barriers identified by various frameworks.

Purpose of the study: This article intends to review the literature on living hadith issues as a social-cultural phenomenon of Indonesia. Methodology: For this article, Systematic Literature Review (SLR) has been used to discuss the data from documents based on the living hadith issues, such as books, journals, and other related materials which had been reviewed and referred to Hadith as the main source. Main Findings: This article found that living hadith is a religious phenomenon that is turned on by society. The phrase living hadith in Indonesia as a term that refers to the contextual practice of hadiths or sunnah that are spelled out of ijma and ijtihad which agreed upon in a Muslim community. In other words, living hadith is an understanding of the meaning of hadith that applied in everyday practices. Applications of this study: This article can be useful for humanity, especially for Muslims when the term of living hadith takes place in society in the form of practices based on the understanding of the hadith of Prophet Muhammad as a second source of Islamic law. Novelty/Originality of this study: The phrase of Living Hadith is not similar among the Muslim community in Malaysia, so it is a new discovery and should be enlightened.

This paper aims to present the quality and its direct influence on important characteristics that dominate the Design of the Supply Network, demonstrating the main aspects involved and the strategy developed to achieve a better performance.  The study is based on a literature review and the main objective of this systematic review of the literature was to identify and classify all previous studies that examined some aspect of network analysis in the context of the supply chain since so far. It provides a detailed description of the most of the subject and contributes with a set of findings that capture the current state of art of the topic. Quality in the supply chain is a new subject and little studied, but it is observed that its influence is present in all sectors of the economy. The classification of Supply Chains has been highlighted as a flow of materials and information that go from suppliers to final customers in the best possible way. With the development of a management that addresses the Supply Chain in a relevant way, the organization can achieve benefits that put it in a competitive position in the market.

Abstract This paper presents a review of the literature on the measurement of creativity. Creativity definitions are discussed as a starting point for understanding the nature of this construct. The four major approaches to measuring creativity (process, person, product and press) are reviewed, pointing out commonly used instruments as well as the advantages and weaknesses of each approach. This review reveals that the measurement of creativity is an unsettled issue, and that the existing instruments purporting to measure creativity suffer from serious conceptual and psychometric shortcomings. Research gaps and suggestions for future research are discussed.
