Understanding lead-time implications for financial performance: a qualitative study
Authors: Tiedemann Fredrik , Wikner Joakim , Johansson Eva 
Published: June 2021

PurposeThe purpose of the study is to describe the implications of strategic lead times (SLTs) for return on investment (ROI).Design/methodology/approachThis study was part of an interactive research project and is based on the logic of theory application leading to theory building. It uses a multiple case study with five holistic single cases. Empirical data (ED) have mainly been collected from interviews and focus groups.FindingsThe length of and uncertainty in SLTs have implications for companies' financial performance. These implications vary in strength and can be either direct or indirect. These findings are incorporated into a framework on SLTs' implications for ROI.Research limitations/implicationsThe presented array of SLTs' implications for ROI could be further investigated, focussing on their strength. Additionally, it would be interesting to substantiate the findings in the context of environmental and social sustainability (i.e. the triple bottom line).Practical implicationsThe findings offer practitioners a rich description and understanding of SLTs' actual implications for financial performance in terms of ROI. This knowledge can support practitioners in analysing supply chain designs based on financial performance.Originality/valueUsing a combination of a relative financial performance measure (ROI) and a set of SLTs (systems perspective), this study focuses on SLTs' actual implications for ROI. The findings provide evidence that different sections of a supply chain can have different implications for revenue, cost and investment (i.e. the three absolute measures related to ROI).

Published: June 2021

PurposeIndustry 4.0 and Lean Production are a successful match in terms of performance improvement. While we understand the combined potential, there is still poor understanding of how companies should embrace digital transformation to make it successful and sustainable, and the role that lean plays in it. In this paper, we investigate how manufacturing companies embark upon digital transformation and how being lean might affect it.Design/methodology/approachWe conducted multiple case studies with 19 manufacturing companies. We identified two clusters of companies according to their Lean maturity, and we assessed digital transformation patterns by analyzing insights coming both from cases and from the literature. Integrating cross-case analysis results, we developed a framework that shows two different digital transformation patterns according to companies’ commitment to Lean.FindingsOur findings first and foremost show the significant role of lean in driving digital transformation. We identify two patterns, namely Sustaining digital transformation pattern, characterized by the pervasive role of lean culture with small and horizontal digital changes, involvement of people and willingness to maintain continuous process improvement, and Disruptive digital transformation pattern, characterized by few and large digital steps that imply a disruptive and radical change in the company system.Practical implicationsEmpirical evidence supports the relevance of the proposed model and its practical usefulness. It can be used to design digital transformation, prepare properly the introduction of Industry 4.0 through a lean approach, and plan the future desired state, identifying the Industry 4.0 technologies that should be implemented.Originality/valueIt is widely recognized that the relationship between Industry 4.0 and lean is significant and positive, yet little evidence was presented to back that. We aim at bringing this debate forward by providing initial empirical evidence of the significant role that lean has on digital transformation, showing how lean drives the digital transformation pattern of companies.
Market structure of short sea shipping in northeast Asia
Authors: Park So-Young , Woo Su-Han , Lai Po-Lin 
Published: June 2021

Purpose
Short-sea shipping (SSS) plays an important role in regional transportation networks by supporting regional trade and improving inter-modality. In particular, countries in north-east Asia, such as China, South Korea and Japan have been served well by local SSS services. While SSS markets in Northeast Asia (NEA) have been developed by bilateral routes with sub-markets, the market structure of each sub-markets varies depending on concentration and competition levels as well as government intervention. The purpose of this paper is to analyse the market structure of SSS markets in the Northeast Asia.

Design/methodology/approach
Herfindahl–Hirschman Index (HHI) and concentration ratio are adopted to measure the market concentration from 2013 to 2017 for SSS markets in NEA. Additionally, the balance between supply and demand is investigated by measuring the capacity utilisation factor (CUF) based on slot capacity.

Findings
The market structure in the NEA SSS markets is influenced by firms’ behaviour under different levels of governmental intervention. Shipping firms in a market with more governmental intervention in market entry tend to focus on balancing supply and demand rather than increasing market share, whereas firms in a market with less intervention (and more competition) tend to increase their market share by pursuing efficient capacity management.

Research limitations/implications
The period of data set is limited to 2013–2017. Furthermore, prices or revenue for specific routes are not available.

Originality/value
This paper sheds light on the market structure and behaviour of players in SSS market. In addition, the work has value to measure capacity utilisation based on slot capacity.
Student-managed investment funds: a review and research agenda
Authors: Abukari Kobana , Oldford Erin , Willcott Neal 
Published: June 2021

PurposeIn recent years, student-managed investment funds (SMIFs), experiential learning programs at an increasing number of universities, have attracted significant scholarly interest. In this article, we review the academic literature on this pedagogy.Design/methodology/approachWe use the systematic review method to assess a sample of 85 articles published in 30 journals during the period 1975 to 2020.FindingsOur literature review reveals four streams of research: best practices and challenges, investment management, innovation and trends and SMIFs in a research setting. We also propose future research directions, including specific gaps in the literature, a focus on innovations to traditional programs, systematic investment performance and expansion into behavioral finance issues.Originality/valueWe contribute a comprehensive view of the body of scholarship on SMIFs, identifying existing streams of research and future research directions that will help guide the development of SMIF research into a cohesive and productive space.
Agency costs in the market for corporate control: evidence from UK takeovers
Authors: Jones Edward , Xu Bing , Kamp Konstantin 
Published: June 2021

PurposeThis paper aims to examine whether agency costs predict disciplinary takeover likelihood for the UK listed companies between 1986 and 2015.Design/methodology/approachUsing survival analysis, the approach is to identify candidates for disciplinary takeover on the basis of Tobin’s Q (TQ), which is consistent with the approach advocated by Manne (1965). This study then examines how indicators of agency costs affect takeover likelihood within the set of disciplinary candidates.FindingsThis paper provides evidence of the effectiveness of TQ, rather than excess return, in identifying disciplinary takeover candidates. Takeover hazard for disciplinary candidates is higher for companies with higher levels of asset utilization and sales growth in particular. Companies with stronger agency problems are relatively less susceptible to disciplinary takeover.Practical implicationsGiven the UK context of the study, where anti-takeover provisions are disallowed and when compared to findings of US studies, the results imply some support for the effectiveness of an open merger policy.Originality/valueWhile the connection between takeover likelihood and the market for corporate control has been made in previous studies, the study adopts a more explicit agency theory framework than previous studies of takeover likelihood. A key component of the contribution follows from differentiating candidates for disciplinary takeovers from other forms of mergers and acquisitions.
Tilting separation simulation and theory verification of mask projection stereolithography process
Authors: Wu Xiangquan , Xu Chunjie , Zhang Zhongming , Jin Zhongmin 
Published: June 2021

Purpose
This study aims to accurately simulate the tilting separation process of mask projection stereolithography (MPSL) and verify the tilting theory.

Design/methodology/approach
The finite element separation models of MPSL 3D printing process were established. The established models simulated both tilting and pulling-up separation process by changing the constraints and boundary conditions. The bilinear cohesive curves were used to define the separation interface. The stress distribution of the cured part and FEP film at different times during the whole separation process was extracted. Different orientations of pulling-up and tilting were also compared for stress distribution. The stress change was analyzed for the center and edge points of the upper surface of cured part.

Findings
The results showed that the stress increased with the separation speed, and the stress at the edge position of exposure area was greater than the internal position. The tilting traction stress distribution was affected by the exposure area function and the velocity distribution. Alternation of the exposure area function changed the cohesive stiffness. The non-coincidence of the calculated traction stress with the input bilinear cohesive curve reflected the influence of the material properties and the separation methods. The high-speed side of tilting had fast separation and high traction stress.

Originality/value
This study proposes a technical method for simulation tilting separation and verified the tilting theory. The cohesive zone model was proved applicable to the tilting traction stress calculation.
Constructing citations: reviewing chat transcripts to improve citation assistance as a service
Authors: Wilkinson Jaci , Denneler Alyssa , Nay Leanne , Johnson Anna Marie 
Published: June 2021

PurposeUsing chat transcripts from Indiana University Libraries, the authors examined a subset of transcripts involving citations. From this analysis, they propose improvements for citation assistance as a holistic service.Design/methodology/approachTwo years of chat transcripts were examined and questions containing citation-related keywords were segregated for further examination. The authors used a test data set to create a coding scheme for the questions and responses. This scheme was then applied to all the citation-related transcripts.Findings390 of 11,553 transcripts included interactions about citations. In 42% of the transcripts, no specific citation style was mentioned. American Psychological Association and Modern Language Association were the most frequently mentioned citation styles by chat users. Business reports (company data and market research), periodicals (journal, newspaper or magazine articles), websites and government documents were the most often asked about formats, but there was a wide variety of other unusual formats. Questions about EndNote were more common than other types of citation management software. Chat staff utilized a variety of responses including guiding the student by example, directing to an online resource for more information (85% of the responses) or referring to a citation management expert. An unexpected amount of hedging words in the responses indicates the presence of anxiety on the part of chat staff in responding to these types of questions.Originality/valueThis paper goes beyond most existing studies of chat transcripts by using chat transcripts as data to guide service improvements for a commonly asked but not typically discussed set of questions.
Clusters or networks: interorganizational relationships influence on Brazilian hotel performance
Authors: Vieira Daniel Pires , Hoffmann Valmir Emil , Reyes Junior Edgar , Boari Cristina 
Published: June 2021

Purpose
Although interorganizational relationships are acknowledged as positive for tourism, studies on the subject fail to systematically analyze the joint effects of relationships with different types of organizations. The purpose of this paper is to analyze the influence of the interaction between different types of interorganizational relationships over a hotel firm’s performance.

Design/methodology/approach
A structured questionnaire applied to hotel managers was used to assess hotel relationships. Hotel performance was assessed through Trip Advisor information. Structural equations modeling (SEM) was used for data analysis.

Findings
Results reveal that only relationships with other hotels had a significant influence on performance. The competition had a negative effect on hotel performance, as well as on horizontal and support organization relationships. Relationships with support organizations presented a significant effect on the formation of relationships between companies (horizontal and vertical) and mediated the negative effect of competition over horizontal relations.

Practical implications
Hotel relationships are idiosyncratic and path-dependent, hence monitoring and copying competitors’ relationships is not advisable. Hotels may improve their productive integration by relating with support organizations. From a destination management perspective, results show that support organizations facilitate interfirm relationships and productive integration within a destination.

Originality/value
The paper systematically analyzes the influence of different interorganizational relationships and competition on hotel performance. Empirical results contradict some aspects of networks and clusters. Some relationships may have positive effects on destinations, but not on hotel firms. Additionally, support organizations play a central role on interfirm relationship formation and maintenance.
Imaging complex three‐dimensional structures, applying three‐component vector migration to synthetic vertical seismic profiling data
Authors: Haldorsen Jakob B.U. , Jahren Leif 
Published: June 2021

ABSTRACTBy applying a ray‐based three‐dimensional vector migration process to fully elastic three‐component synthetic Vertical Seismic Profiling data, we are able to demonstrate that the process gives an accurate compressional reflection image of the complex formation without much visible artefacts from spatial aliasing, or from ‘migration smiles’ caused by the limited aperture of the receiver array. We demonstrate that the process reconstructs images of both steeply dipping salt flanks, and the sediments that tend to be dragged along by the moving salt and truncated against the sides of the salt body. The process uses raw unseparated data as input, and the wavefield separation of compressional and shear waves are done by projection operators inside the kernel of the migration process. The compressional reflection image appear to have no visible artefacts from the abundance of converted shear.

Published: June 2021

AimsThe aim of this study was to continually evaluate the association between cardiovascular drug exposure and COVID‐19 clinical outcomes (susceptibility to infection, disease severity, hospitalization, hospitalization length, and all‐cause mortality) in patients at risk of/with confirmed COVID‐19.MethodsEligible publications were identified from more than 500 databases on 1 November 2020. One reviewer extracted data with 20% of the records independently extracted/evaluated by a second reviewer.ResultsOf 52 735 screened records, 429 and 390 studies were included in the qualitative and quantitative syntheses, respectively. The most‐reported drugs were angiotensin‐converting enzyme inhibitors (ACEIs)/angiotensin receptor blockers (ARBs) with ACEI/ARB exposure having borderline association with confirmed COVID‐19 infection (OR 1.14, 95% CI 1.00–1.31). Among COVID‐19 patients, unadjusted estimates showed that ACEI/ARB exposure was associated with hospitalization (OR 1.76, 95% CI 1.34–2.32), disease severity (OR 1.40, 95% CI 1.26–1.55) and all‐cause mortality (OR 1.22, 95% CI 1.12–1.33) but not hospitalization length (mean difference −0.27, 95% CI −1.36–0.82 days). After adjustment, ACEI/ARB exposure was not associated with confirmed COVID‐19 infection (OR 0.92, 95% CI 0.71–1.19), hospitalization (OR 0.93, 95% CI 0.70–1.24), disease severity (OR 1.05, 95% CI 0.81–1.38) or all‐cause mortality (OR 0.84, 95% CI 0.70–1.00). Similarly, subgroup analyses involving only hypertensive patients revealed that ACEI/ARB exposure was not associated with confirmed COVID‐19 infection (OR 0.93, 95% CI 0.79–1.09), hospitalization (OR 0.84, 95% CI 0.58–1.22), hospitalization length (mean difference −0.14, 95% CI −1.65–1.36 days), disease severity (OR 0.92, 95% CI 0.76–1.11) while it decreased the odds of dying (OR 0.76, 95% CI 0.65–0.88). A similar trend was observed for other cardiovascular drugs. However, the validity of these findings is limited by a high level of heterogeneity and serious risk of bias.ConclusionCardiovascular drugs are not associated with poor COVID‐19 outcomes in adjusted analyses. Patients should continue taking these drugs as prescribed.
A systematic review of living kidney donor enhanced recovery after surgery
Authors: Byrne Matthew H. V. , Mehmood Ahmed , Summers Dominic M. , Hosgood Sarah A. , Nicholson Michael L. 
Published: June 2021

AbstractEnhanced recovery after surgery (ERAS) reduces complications and shortens hospital stay without increasing readmission or mortality. However, its role in living donor nephrectomy (LDN) has not yet been defined. Medline, Embase, CINAHL, PsycINFO, and Cochrane Central were searched prior to 08/01/21 for all randomized controlled and cohort studies comparing ERAS to standard of care in LDN. The study was registered on PROSPERO (CRD: CRD42019141706). One thousand, three hundred seventy‐seven patients were identified from 14 studies (698 patients with ERAS and 679 patients without). There were considerable differences in the protocols used, and compliance with general ERAS recommendations was poor. Meta‐analysis of laparoscopic procedures (including hand‐ and robot‐assisted) revealed that duration of stay was significantly reduced by 0.98 days with ERAS (95% CI = 0.36–1.60, P = .002) and opiate requirement by 32.4 mg (95% CI = 1.1–63.7, P = .04). There was no significant difference n readmission rates or complications. Quality of evidence was low to moderate assessed using the GRADE tool. This review suggests there is a positive benefit of ERAS in laparoscopic LDN. However, there was considerable variation in ERAS protocols used, and the quality of evidence was low; as such, a guideline for ERAS in LDN should be developed and validated.
Quantifying potential effect of 2019 fires on national parks and vegetation in South‐East Queensland
Authors: Smith Isabella , Velasquez Eleanor , Pickering Catherine 
Published: June 2021

SummaryFire is a major type of ecological disturbance shaping plant communities and species distributions. Fires in the spring and summer of 2019/2020 in Australia burnt large areas where this type of disturbance was rare in the past, including in the South‐East Queensland region. To assess the potential impacts of these fires, online GIS data layers were used to map where the fires occurred and which protected areas, plant communities and threatened plants were likely burnt. Based on clustering of Visible Infrared Imaging Radiometer Suite sensor fire points, 3% (240,000 ha) of the region may have burnt including 107,606 ha of National Parks, sections of 18 Broad Vegetation Groups and 74 Regional Ecosystems and potential habitat of 74 threatened plant species. This included 16% of wet open forests and 13% of rainforests. The results provide preliminary insights into the potential scale of the fires and impact on biodiversity from mapping based on online data, but we also that more detailed mapping including of fire intensity and perimeter combined with ground truthing and ongoing monitoring would be required to better understand changes in fire regimes in the region.

AbstractObjectivesTo compare the efficacy and patient‐reported outcome measures of oral hygiene instruction methods for calibrated interdental brush.Materials and MethodsA total of 60 participants, with 30 each in control and test group, participated in the study. Clinical examination included gingival index, full mouth bleeding scores and approximal plaque index. Supragingival scaling was performed. Interdental access probe was used to assess the size of interdental brush and corresponding interdental brush were given to the participants. For the control group, oral hygiene instructions were given through demonstration with model and video. For the test group, oral hygiene instructions were given through ‘Touch‐to‐Teach’ method. At 4‐week follow‐up, oral hygiene instructions were repeated to respective groups. After 3 months, clinical examination was done and exit survey on patient‐reported outcome measures was administered. Statistical analysis was done.ResultsIntergroup comparison of gingival index, full mouth bleeding index and approximal plaque index showed statistically significant difference between test and control group. ‘Touch‐to‐Teach’ method of oral hygiene instruction was found to be ‘Good’. Acceptance of interdental brush was regarded to be ‘Good’.ConclusionWithin limitations of the study, Touch‐to‐Teach method of oral hygiene instruction method was found to be effective and more acceptable and participants used the interdental brush regularly.
