A data set of comparable estimates of the private rate of return to schooling in the world, 1970–2014
Authors: Montenegro Claudio E. , Patrinos Harry Anthony 
Published: October 2021

PurposeYoung people experience lower employment, income and participation rates, as well as higher unemployment, compared to adults. Theory predicts that people respond to labor market information. For more than 50 years, researchers have reported on the patterns of estimated returns to schooling across economies, but the estimates are usually based on compilations of studies that may not be strictly comparable. The authors create a dataset of comparable estimates of the returns to education.Design/methodology/approachThe data set on private returns to education includes estimates for 142 economies from 1970 to 2014 using 853 harmonized household surveys. This effort holds the constant definition of the dependent variable, the set of controls, sample definition and the estimation method for all surveys.FindingsThe authors estimate an average private rate of return to schooling of 10%. This provides a reasonable estimate of the returns to education and should be useful for a variety of empirical work, including critical information for youth.Originality/valueThis is the first attempt to bring together surveys from so many countries to create a global data set on the returns to education.
Thank you for sharing! How knowledge sharing and information availability affect public employees’ job satisfaction
Authors: Fischer Caroline , Döring Matthias 
Published: October 2021

PurposeThis study aims to examine the impact of job-related knowledge sharing on information availability and job satisfaction for information-receiving employees in the public sector. Following self-determination theory, the study suggests that job satisfaction is only partly affected by knowledge sharing itself, but particularly through the availability of job-related information enabling the information receiver to work effectively.Design/methodology/approachThe hypotheses are tested with data from the US Federal Employee Viewpoint Survey from 2018. Additionally, results are replicated with earlier waves of the survey.FindingsResults show the positive impact of job-related knowledge sharing on job satisfaction, whereby the availability of job-relevant information mediates this relationship partially.Practical implicationsThis study confirms that managers should provide room for social interactions when introducing knowledge management practices.Originality/valueThe results emphasize that knowledge sharing is a highly social process in which support and relatedness play a significant role in success in addition to the diffusion of information itself.
Understanding misinformation and rumors that generated panic buying as a social practice during COVID-19 pandemic: evidence from Twitter, YouTube and focus group interviews
Authors: Naeem Muhammad , Ozuem Wilson 
Published: October 2021

PurposeThe purpose of the study is to understand how socially shared misinformation and rumors can enhance the motivation to protect personal interests and enhance social practices of panic buying.Design/methodology/approachThe study employed a number of qualitative data collection methods for the purpose of triangulation, as it can offer thick interpretation and can help to develop a context specific research framework.FindingsThe shared misinformation and rumors on social media developed into psychological, physical and social threats; therefore, people started panic buying to avoid these negative consequences. People believed that there were differences between the information shared by politicians and government officials and reality, such as “everything is under control,” whereas social media showed people standing in long queues and struggling to buy the necessities of life. The shared misinformation and rumors on social media became viral and received social validation, which created panic buying in many countries.Research limitations/implicationsIt is the responsibility of government, politicians, leaders, media and the public to control misinformation and rumors, as many people were unable to buy groceries due either to socio-economic status or their decisions of late buying, which increased depression among people.Originality/valueThe study merged the theory of rumor (TORT) transmission and protection motivation theory (PMT) to understand how misinformation and rumors shared through social media increased global uncertainty and the desire to panic buy across the world.
Exploring library management support for enhancing self-directed learning: narratives from research-support librarians
Authors: Samah Nazrinda A. , Mohd Tahir Lokman , Wan Mamat Wan Ali @ Wan Yusoff 
Published: October 2021

PurposeThis qualitative study explores the issue of library management support in providing a self-directed learning environment for research-support librarians which is an under-explored feature of librarianship in Malaysian public university libraries.Design/methodology/approachA total of nine research-support librarians purposely selected from these libraries took part in in-depth interview sessions. The responses were analysed using Miles and Huberman's technique, which involves data reduction, data display, conclusion-drawing and verification.FindingsFive emerging themes and 31 sub-themes were identified. There was a general consensus among the respondents that their library management does provide research-support librarians with a self-directed learning environment to enhance their competencies as academic librarians. Nevertheless, these librarians also highlighted some challenges, issues and barriers related to the initiative and support received. Some suggestions are advanced for improvements to support self-directed learning by research-support librarians working in public university libraries.Originality/valueEmpirically, this study attempts to fill the gap in the knowledge that needs to be addressed from the perspective of Malaysian librarians, especially the research-support librarians, who serve in public universities in Malaysia, who have received little attention from local librarianship researchers.
Exploring the critical success determinants for supply chain management in modular integrated construction projects
Authors: Wuni Ibrahim Yahaya , Shen Geoffrey Qiping 
Published: October 2021

PurposeModular integrated construction (MiC) projects are co-created by a network of organizations and players providing different roles, information and activities throughout the supply chains. Hence, a successful delivery of MiC projects can hardly be decoupled from effective supply chain management (SCM). This study investigated the critical success determinants of effective SCM in MiC projects.Design/methodology/approachComprehensive literature research and expert review identified 20 candidate success determinants, which formed the basis for a structured questionnaire survey of experts in eighteen countries. The study computed the mean scores, normalized mean values and significance indices of success determinants for SCM in MiC projects.FindingsThe analysis revealed that design for SCM, effective communication and information sharing, organizational readiness and familiarity with MiC, seamless integration and coordination of supply chain, early involvement of critical supply chain stakeholders and extensive supply chain planning are the top five critical success determinants of effective SCM in MiC projects. The 20 success determinants are categorized into five: project strategy, bespoke competencies, process management, stakeholder management and risk management.Research limitations/implicationsThe study has some limitations. The smaller sample size could affect the generalizability of the results. The generalized analysis of the success determinants overlooked their sensitivities to specific contexts, industry climates and project types.Originality/valueThe study established a novel set of critical success determinants for SCM in MiC projects that have not been explicitly discussed in the MiC success literature and described their hypothetical dynamic linkages. It contributes to a better understanding of how best to manage the MiC project supply chain effectively.

Published: October 2021

PurposeThe purpose of this study is to minimize cost and minimize building condition. Weibull distribution approach was employed to generate deterioration curves over time. The third floor of Concordia University’s Engineering And Visual Arts (EV) Complex in Montreal, Canada, served as a case study to test the maintenance model and determine the optimal maintenance activities to be performed.Design/methodology/approachThis research has demonstrated that there is insufficient fund allocation for the maintenance of non-residential buildings. Therefore, this research focused on designing and developing a maintenance optimization model that provides the type of spaces (architectural system) in a building. Sensitivity analysis was used to calculate weights to validate the model. Particle swarm optimization, based explicitly on multiple objectives, was applied for the optimization problem using MATLAB.FindingsFollowing 100 iterations, 13 non-dominant solutions were generated. Not only was the overall maintenance cost minimized, but the condition of the building was also maximized. Moreover, the condition prediction model demonstrated that the window system type has the most rapid deterioration in educational buildings.Originality/valueThe model is flexible and can be modified by facility managers to align with the required codes or standards.
Fluorescence quenching-based bodipy-boronic acid linked viologen dual system for potential glucose sensing applications
Authors: Demirel Topel Seda , Beyaz Mustafa İlker 
Published: October 2021

Purpose
The purpose of this study is to develop a non-enzymatic based glucose-sensing platform composed of Bodipy-BBV dual system which can be monitored by a photodetector under the blue LED excitation.

Design/methodology/approach
The sensor has been developed from a dual system including a fluorescent dye, an aldehyde derivative of boron dipyrromethene (Bodipy) and a quencher, orto-boronic acid linked viologen (o-BBV) where their combination resulted in a ratiometric fluorescence quenching in ethanol: PBS (1:1, pH:7.4) solution under UV light excitation. By glucose addition, o-BBV has been released from the Bodipy and binded to cis-diol groups of glucose, thereby fluorescence emission of Bodipy has been regained. Furthermore, a setup consisting of a light emitting diode (LED) and a photodiode (PD) was used to prove electrical detection of glucose without the need for expensive and bulky optical equipment, enabling the development of a miniaturized and low-cost glucose-sensing platform.

Findings
The fluorescence intensity of the Bodipy derivative in the solution (2 × 10−6 M) was diminished by 93% in the presence of o-BBV solution (5 × 10−3 M). Upon the glucose addition, 81% of the Bodipy fluorescence intensity has been recovered after introduction of 30 mM of glucose, where the ratio of o-BBV/Bodipy was 35:1. A linear response between 10 and 30 mM glucose concentration was obtained, which covers the biologically significant range. A high correlation between the photodiode current and Bodipy fluorescence intensity was achieved.

Originality/value
Even though Bodipy molecules are known with their superior optical properties and applied to the fluorescence-based detection of glucose, to the best of the authors’ knowledge, no work has been reported on Bodipy-BBV dual system to detect glucose molecules as a non-enzymatic based method. This design enables the dye and the quencher to independently coexist in the solution, allowing for tuning of their individual concentrations to optimize the glucose sensitivity. Furthermore, an electrical light detection scheme consisting of a LED and a photodiode has been implemented to eliminate the bulky optical equipment from the measurement setup and further this work for the development of a compact and inexpensive sensor. The results presented here demonstrate the feasibility of this system for the development of a novel glucose sensor.

It provides in-depth bibliometric analysis of articles and identification of the important research trends.
Macroalgal and mangrove provenances demonstrate their relevance in contributing to the blue carbon pool of a tropical seagrass meadow
Authors: Hidayah Nur , Ng Chiew Tsann , Arina Natasha , Fairoz Mohammad , Rozaimi Mohammad 
Published: October 2021

AbstractMangroves, seagrasses and macroalgae form inter‐connected coastal habitats. They are involved in the direct and indirect sequestration and accumulation of blue carbon and are recognized for their role in climate change mitigation. Macroalgae, though residing within or in close proximity to these ecosystems are, however, not perceived as contributing to blue carbon storage. Such habitat connectivity among the mangrove, seagrass, and macroalgal compartments complicates a straightforward assessment of blue carbon storage. In this study, we assessed the contributions of these macrophytes as endmembers to the bulk organic carbon (OC) stocks in surficial (top 30 cm) and deep (31–100 cm) sediment layers of seagrass beds within the Sungai Pulai estuary (Malaysia). Organic carbon stocks in the seagrass sediments ranged from 14.3 to 21.4 Mg OC ha−1 (surficial depths), and 137.9 ± 23.3 (mean ± SE) Mg OC ha−1 for the deep layer. Mangrove‐derived matter contributed a maximum of 65% to the bulk OC pool. The existence of downcore variability indicated that macroalgae contributed up to 16% and were higher than seagrass sources (12%). Our results suggest that macroalgal‐derived and mangrove‐derived organic matter are important contributors to OC sequestration in the estuary. In view of the heterogeneous OC pool that contributes to bulk OC stocks, placing importance on only one OC source may construe an incomplete profile of habitat‐specific capacity for OC storage. This has wider implications for understanding OC subsidies, the effects of which are particularly relevant when one considers the impacts of coastal land use changes on blue carbon storage.
Massive investments in flowers were in vain: Mass flowering after a century did not bear fruit in the bamboo Phyllostachys nigra var. henonis

Published: October 2021

AbstractPhyllostachys nigra var. henonis (Poales: Poaceae) is a tall, temperate bamboo species that has a long monocarpic life history with a flowering interval of around 120 years that is often conspicuously synchronized across a wide geographical area. Interestingly, observations of the last major flowering event, which was about a century ago, suggested that mature seeds were rarely produced as a consequence. As this bamboo has recently started flowering across Japan after a century of silence, we seek to understand its reproductive strategy by quantifying the following four issues: (1) flowering patterns within stands, (2) the presence or absence of mature seeds, (3) resource allocations to reproductive parts, and (4) asexual regrowth capacity after mass flowering. We conducted field surveys at five flowering bamboo stands in Japan. At each, many spikelets were found, but neither mature seeds nor seedlings. During the mass flowering, large amounts of resources were allocated to reproductive parts, accounting for 57% of the aboveground nitrogen pool and 63% of the aboveground phosphorus pool. These results indicate that the accumulated resources were used for flowers, but not for seed production, and thus apparently in vain. While most of the flowering ramets appeared to die, dwarf ramets (mostly less than 1 m in height) typically regenerated from the remaining belowground rhizomes and seem to be critical for maintaining the bamboo stands. This apparently inefficient sexual reproductive strategy still exists (without local extinction) perhaps due to the vigorous clonal growth system and to human‐assisted distribution.
Paragons, Mavericks and Innovators—A typology of orthopaedic surgeons' professional identities. A comparative case study of evidence‐based practice
Authors: Grove Amy , Pope Catherine , Currie Graeme , Clarke Aileen 
Published: October 2021

AbstractClinical guidelines, as vehicles for evidence‐based practice (EBP) attempt to standardize health‐care practice, reduce variation and increase quality. However, their use for surgery has been contested, and often resisted. This article examines professional responses to EBP in hip replacement surgery using data from case study observations and interviews in three English orthopaedic departments. A professional identity perspective is adopted to explain how standardization through EBP, represents an empirical phenomenon around which surgeons enact their identities as Paragons, Mavericks or Innovators, to enhance legitimacy and stratify themselves in their response to EBP. Attention is drawn to variation between Paragon surgeons working in university (teaching) hospitals and Maverick and Innovator types located in general hospitals, and the ways this interacts with adoption of EBP. The typology shows how practice variation is related to surgeons' tendencies to align to characteristic types, with distinct social processes, power and prestige, and which are in turn influenced by organizational context. The dynamics of EBP and professional identity continues to limit attempts to standardize surgical practice. The typology contributes to the understanding of failures to follow EBP, as associated with the identities individuals create and negotiate, and with identity narratives used to legitimize differing responses to EBP.

AbstractObjectiveTo report the arrival ionised calcium (iCa) and fibrinogen concentrations in trauma patients treated with packed red blood cells by the road‐based high‐acuity response units of a metropolitan ambulance service.MethodsA retrospective review of trauma patients treated with packed red blood cells by high‐acuity response units between January 2012 and December 2016. Patients were identified from databases at southeast Queensland adult trauma centres, Pathology Queensland Central Transfusion Laboratory, Gold Coast University Hospital blood bank and the Queensland Ambulance Service. Patient characteristics, results of laboratory tests within 30 min of ED arrival were analysed.ResultsA total of 164 cases were analysed. The median injury severity score was 33.5 (interquartile range 22–41), with blunt trauma the commonest mechanism of injury (n = 128, 78.0%). Fifty‐eight of the 117 patients (24.4%) with fibrinogen measured had a fibrinogen concentration ≤1.5 g/L; 79 of the 123 patients (64.2%) with an international normalised ratio (INR) measurement had an INR >1.2; 97 of 148 patients (63.8%) with an iCa measured, had an iCa below the Pathology Queensland reference range of 1.15–1.32 mmol/L. Arrival fibrinogen concentration ≤1.5 g/L and arrival iCa ≤1.00 were associated with in‐hospital mortality with odds ratio 11.90 (95% confidence interval 4.50–31.65) and odds ratio 4.97 (95% confidence interval 1.42–17.47), respectively.ConclusionsHypocalcaemia and hypofibrinogenaemia on ED arrival were common in this cohort. Future work should evaluate whether outcomes improve by correction of these deficits during the pre‐hospital phase of trauma care.
A standardized effect size for evaluating and comparing the strength of phylogenetic signal
Authors: Collyer Michael L. , Baken Erica K. , Adams Dean C. 
Published: October 2021

AbstractMacroevolutionary studies frequently characterize the phylogenetic signal in phenotypes; however, analytical tools for comparing the strength of that signal across traits remain largely underdeveloped.We developed a non‐parametric, permutation test for the log‐likelihood of an evolutionary model, plus a standardized statistic,, from this test, which can be considered a phylogenetic signal effect size. This statistic can be used in two‐sample tests to compare the strength of phylogenetic signal for multiple traits.We performed simulation experiments that revealed thathad a linear association with Pagel's, which could be predicted by tree size, plus could be quickly interpreted as a hypothesis for phylogenetic signal based on a standard normal distribution. We additionally found that the permutation test had greater statistical power for detecting phylogenetic signal than parametric likelihood ratio tests, especially for small trees.The analytical framework we present extends the phylogenetic comparative methods toolkit, allowing for statistical comparison of phylogenetic signal in multiple traits. Future studies could also consider this framework for the comparison of different evolutionary models, especially in light of different null processes.
