Published: June 2020

PurposeThe selection of effective library software not only plays an important role for students, academic staff and the library staff but also helps an institution by having the library management system more centralized. Therefore, the aim of this study is to develop a multiple-criteria decision analysis (MCDA) cause and effect factor model for the implementation of the Greenstone Digital Library (GSDL) software.Design/methodology/approachA thorough review of the literature is conducted to develop an initial list of the appropriate evaluation factors that play a significant role in the implementation of GSDL software. The data were collected from a domain of experts in the library sciences field. A combined approach of Delphi-DEMATEL methods is employed for the definition of these factors and to construct an MCDA cause-effect model which represents their relationships.FindingsThe DEMATEL analysis resulted in the division of all factors into two groups, causes and effects. The results show that content management, having a user-friendly interface and usability, information search and retrieval and authentication and authorization fall into the cause group. These factors directly affect the remaining factors. Content acquisition, classification, access, control and privacy management and metadata submission and support fall into the effect group. The research findings can help library professionals to make effective decisions to facilitate the successful implementation of GSDL software in a library and the enhancement of library technology.Practical implicationsThe results of this study can be useful for library professionals and decision-makers to select the most appropriate software for the implementation of library technology. The study analysis shows that for GSDL, user-friendly interface and usability, information search and retrieval plus authentication and authorization factors have seven positive relationships with other factors. Secondly, content management and classification have six relationships with other factors. Thirdly, access control plus privacy and management have two relationships. Content acquisition has only one relationship with other factors. It is recommended that the user-friendly interface and usability, information search and retrieval, as well as authentication and authorization should be the initial areas of focus if GSDL is to be implemented successfully in digital libraries.Originality/valueThe proposed MCDA cause-effect model can be useful for library professionals or decision-makers in the context of selecting software to be implemented in a library and to minimize implementation costs.

Published: June 2020

PurposeThis study aims to identify the legitimacy issues raised during a sustainable business model innovation, deployed by an Italian company, which was analyzed through the lens of the legitimation theory and the business model innovation theory.Design/methodology/approachA single case study methodology is employed for empirical research. Semistructured interviews, with top and middle management, were conducted together with the analysis of several internal and external documents, to corroborate the case analysis.FindingsResults show how the potentiality of digital technologies allows the development of new sustainable business models, which, though, still need to gain legitimation to be accepted. The study findings allow drawing both on the business model innovation theory and on the legitimation theory, as they show how legitimation is a dynamic concept that involves internal as well as external stakeholders to support business model innovation.Originality/valueThe paper is novel, since it addresses the topic of sustainable business models development, showing how companies can get legitimation. The paper builds on existing theories and provides a practical example.

Published: June 2020

PurposeIn Southeast Asia, the renewable energy produced from hydropower systems has significant potential. Therefore, adequate development is needed to prevent future energy-related crises. This study, therefore, aims to determine the variations effects in geometry and the geometrical factors on turbine performance.Design/methodology/approachThe developed aspects are selected to determine the blade shape, its number and multistage requirements. The study was conducted in 3D simulation, with Ansys software used to calculate a series of computational fluid dynamic problems. The aspect ratio applied in this study utilized the ratio of the overall diameter of the rotor height (D / H), which is 1.FindingsThe results showed that the highest Cp-max value, number of blades and stages were 0.2, two and three, respectively. Furthermore, these attributes combined to improve the performance of hydroturbines.Research limitations/implicationsThe research was fully conducted using numerical simulation, which requires sustainable research in the form of laboratory experiments. Also, pioneer experiments were conducted using benchmarking to ensure the results obtained are reliable.Practical implicationsHydropower is one of the best renewable energy sources in Indonesia with a large potential in the archipelago and tropical countries due to rivers and various water sources. The current generated is a useful reference for Savonius design.Originality/valueThe originality of this study is to examine the three aspects of the geometry of the rotor, such as the number and shape of blades, as well as the stages in the same boundary conditions. Therefore, the comparison of the effects of changes in geometry on turbine performance is more acceptable and complete compared to the pioneer works, which focused on a parameter. This research combines several aspects to determine the effect of rivers and various water sources on the hydroturbine.
Osmo-predried fluted pumpkin (Telfairia occidentalis) leaf and its nutri-economic evaluation
Authors: Ajala Lawrence Olusegun , Igidi John O. , Fasuan Temitope Omolayo , Ominyi Chidinma Emmanuel 
Published: June 2020

Purpose
Leafy vegetables are known to be highly perishable because of high moisture content, which had resulted in applications of different preservative methods. However, these methods were not without certain limitations during storage. Osmotic pre-dehydration had been proved to be a better alternative because of high retention and improvement in nutritional qualities and stability during storage. This study aims to investigate the osmotic pre-dehydration of fluted pumpkin (Telfairia occidentalis) leaves.

Design/methodology/approach
Fluted pumpkin (T. occidentalis) leaves were pre-dried using sucrose, corn syrup and sodium chloride solutions as osmotic agents, while unosmo-predried leaves were used as the control. Both osmo-predehydrated and unosmo-predried leaves were dried in a hot air oven, whereas the effect of the osmotic agents on the nutritional qualities was investigated using standard protocols.

Findings
There were significant differences (p-values ranged from 0.001 to 0.030) in the proximate compositions of samples. Osmo-predried leaves recorded higher mineral contents in Ca, Cu, Fe, K, Mg, Mn and Na. Osmotic pre-dehydration by NaCl had a significant effect (p = 0.02) on ascorbic acid. The amino acid profile of the oven-dried leaves (unosmo-predried) showed that histidine and cysteine recorded high amino acid scores of 120.42% and 135%, respectively. Threonine (43.73%) recorded the highest essential amino acid score (without histidine). The economic evaluation indicated the percentage cost index difference of leaves treated with NaCl as 2.08%, sucrose (11.19%) and corn syrup (16.43%).

Originality/value
The high proportion of beneficial elements such as calcium, magnesium, phosphorus, potassium and appreciable chemical compositions of the osmo-predried leaves compared to unpre-dried leaves proved osmotic pre-dehydration as a value-added technique for preservation of leafy vegetables. The best osmotic agent was sodium chloride. This process could be applied on a small scale for the development of self-entrepreneurs and home-scale industries.
Creating operational alpha? Operating models for real estate management
Authors: McAllister Pat 
Published: June 2020

PurposeFocussing on the UK’s institutional real estate universe, this paper analyses variations in the operational management of real estate investment portfolios. For the main categories of institutional investors, the key tasks in real estate operational management, and the ways in which these tasks are typically bundled and categorised by investment managers are reviewed. Three broad operational management models are outlined. Case studies of real estate operational management models in practice are discussed.Design/methodology/approachThe research approach is primarily descriptive, drawing upon illustrative investor case studies.FindingsA range of operating models are identified for managing real estate investment portfolios. Specialists real estate investors tend to have highly vertically integrated operating models viewing most operational management functions as core operational capabilities. Multi-asset owners tend to have a vertically disintegrated operating model outsourcing fund, asset, property and facilities management. Investing institutions such as fund houses and specialist real estate investment advisors seem to have converged upon a common hybrid operating model with high margin, analytical functions such as fund and asset management being insourced and low margin, routine functions such as property and facilities management being outsourced.Originality/valueDespite the size of the global, institutional real estate investment universe (estimated by DTZ to be worth more than USD 13.6 trillion in 2015), the topic of how (and how effectively) these assets are managed by institutional investors has attracted very little attention from the real estate research community. This paper provides some initial analysis and insights into operational management models for real estate investment portfolios in the contemporary real estate investment management landscape.
An evaluation of the effect of interconnectedness and the state of the relationships in a triad: a dynamic approach
Authors: Tjandra Nathalia Christiani , Ensor John , Omar Maktoba , Thomson John R. 
Published: June 2020

PurposeThis study aims to investigate the applicability of Ritter’s (2000) framework of interconnectedness in a triadic relationship between a provider, intermediaries and customers and to extend the framework by considering how the state of the relationships in a triad influences the relationship dynamic.Design/methodology/approachA qualitative case study research method with multiple sources of evidence was adopted in this study. The case study focusses on a triadic relationship of one of the largest UK-based financial services institutions, Provider XYZ, with independent financial advisers and customers.FindingsThe findings confirm that the synergy effect, lack effect, competition effect and by-pass effect exist in the triadic relationship. The findings also acknowledge that the state of the relationships in a triad, whether they are positive (+), negative (−) or neutral (0), combined with the identified interconnectedness effect determine the dynamic of the triadic relationship network.Originality/valueThis paper extends the existing framework of interconnectedness by considering how the change of the relationship state changes the relationship dynamic in a triad. By evaluating both the effect of interconnectedness and the state of the relationships in a triad, managers can identify and manage possible conflicts in a triad and enhance the effectiveness of the triadic relationship.
Can a supplier benefit from investing in transaction-specific investments? A multilevel model of the value co-creation ecosystem perspective
Authors: Huang Ming-Chang , Kang Min-Ping , Chiang Jui-Kun 
Published: June 2020

Purpose
This paper aims to build and empirically test a multilevel framework integrating transaction cost economics and a resource-based view into a value co-creation ecosystem perspective to explain the chain- and firm-level effects of transaction-specific investments (TSIs) on supplier performance.

Design/methodology/approach
This paper investigates cross-level network effects using survey data from the List of Taiwanese Central Satellite Production Systems. A total of 34 buyers (hub firms) and 106 suppliers (satellite firms) from 34 supply chains responded to the survey.

Findings
Findings confirm that individual firms’ TSIs can foster co-specificity at the supply chain level, thereby improving supply chain integration (SCI). SCI can have a positive cross-level moderating effect on the TSI–performance relationship.

Research limitations/implications
These two key concepts, value co-creation and co-specificity, extend the theoretical application of transaction cost theory and the resource-based view to cross-level study by contributing to the research on the TSI–performance relationship.

Practical implications
This study’s framework is a counter to the buyer–supplier–supplier relationships in which each actor who may have different goals can create value jointly and share benefits from their TSIs.

Social implications
Owing to high co-specificity, being embedded in a well-integrated supply chain can be a threat when the environment is turbulent; for losing strategic flexibility, co-specificity and embeddedness may result in a collective adaptation concern. High degrees of SCI may slow the reaction to environmental turbulence for both buyers and suppliers.

Originality/value
Individual firms’ TSIs can foster co-specificity at the supply chain level, subsequently enhancing SCI. An integrated supply chain can be a collective asset that facilitates value co-creation. Individual firms can benefit from the sharing of collective value. SCI can also increase switching costs, thus reducing the likelihood of individual firm engaging in opportunistic behavior and cost safeguarding.
Accurate profile measurement method for industrial stereo-vision systems
Authors: Zhang Yang , Liu Wei , Lu Yongkang , Cheng Xikang , Luo Weiqi , Di Hongtu , Wang Fuji 
Published: June 2020

Purpose
Profile measurement with boundary information plays a vital role in the detection of quality in the assembly of aviation parts. The purpose of this paper is to improve the evaluation accuracy of the aerodynamic shapes of airplanes, the profiles of large-sized parts need to be measured accurately.

Design/methodology/approach
In this paper, an accurate profile measurement method based on boundary reference points is proposed for the industrial stereo-vision system. Based on the boundary-reference points, the authors established a priori constraint for extracting the boundary of the measured part. Combining with the image features of background and the measured part, an image-edge compensation model is established to extract the boundary of the measured part. The critical point of a laser stripe on the edge of the measured part is extracted corresponding to the boundary constraint. Finally, as per the principle of binocular vision, the profile of the measured part is reconstructed.

Finding
Laboratory experiments validate the measurement accuracy of the proposed method which is 0.33 mm. In the analysis of results between the measured data and the theoretical model, the measuring accuracy of the proposed method was found to be significantly higher than that of the other traditional methods.

Practical implication
An aviation part was measured in the part-assembly shop by the proposed method, which verified the feasibility and effectiveness of this method. The research can realize the measurement of smooth surface boundary which can solve existing profile reconstruction problems for aviation parts.

Originality/value
According to the two-dimensional contour constraint, critical points of the laser strip sequence at the edge of measured part are extracted and the accurate profile reconstruction with the boundary is realized.
Thinking with theory in a civil rights center
Authors: Adams Erin C. , An Sohyun 
Published: June 2020

PurposeThe purpose of this theoretical paper is to propose that museums can be useful sites in intervening the theory–practice divide in teacher education. The authors draw from their visit to the Center for Civil and Human Rights (CCHR or Center hereafter) to explore the potential of a local museum as a powerful intervention in the preservice teacher education theory/practice divide.Design/methodology/approachThe authors’ theoretical framework draws off of “thinking with theory,” a method of using concepts to make sense of data by “plugging” a concept “into” data (Jackson and Mazzei, 2011). The authors believe that everyone, even their preservice teachers think with theories in an attempt to make sense of information and events. In their social studies methods courses, the authors offer readings, texts, videos and experiences that present ideas and concepts that are new to their preservice teachers in order to expose underlying theories that frame worldviews.FindingsThe authors provide four “snapshots” or findings. These include: heroification and villainification, White–Black binary and messianic meta-narratives, empathy and simulation and critical Black patriotism. Each of these snapshots is grounded in theories from scholars in the field of social studies, demonstrating one way to put theory to work.Originality/valueAs the aforementioned snapshots show, the authors found a place like CCHR that can serve as important space to think with theory and deconstruct presented narratives. The authors “plugged” concepts from social studies scholarship “into” the narratives presented at the CCHR. Specifically, the authors used villainification (van Kessel and Crowley, 2017), AsianCrit (Chang, 1993), Black Patriotism (Busey and Walker, 2017) and messianic narratives and martyrdom (Alridge, 2006).
Sensory co‐evolution: The sex attractant of a gall‐making fly primes plant defences, but female flies recognize resulting changes in host‐plant quality

Published: June 2020

Abstract

Tall goldenrod plants Solidago altissima appear to eavesdrop on the communication of a specialist gall‐inducing fly Eurosta solidaginis by detecting the volatile emissions of male flies and priming anti‐herbivore defences. However, the effects of defence priming on fly fitness have not previously been demonstrated, despite some evidence that female flies avoid ovipositing on primed plants in the field.

To explore how priming affects female preferences and galling success, we manipulated exposure to the priming cue in multiple genotypes of S. altissima and assessed rates of oviposition and gall development.

Priming reduced gall formation overall; however, its effect varied across plant genotypes, as well as by the age of the male flies used for priming, possibly reflecting dosage effects (older flies produce lower emissions). Priming by younger males significantly reduced galling success, while priming by older males slightly improved it. Remarkably, female flies accurately assessed host‐plant quality by avoiding plants primed by young males while preferring those primed by older males.

Synthesis. Our results suggest that defence priming in S. altissima in response to the volatile emissions of E. solidaginis males does affect fly fitness; however, the effect of priming varied by plant genotype, suggesting that there may be variation in defensive strategies against the fly. Female flies have, in response to this defence, evolved a sophisticated ability to evaluate the quality of primed plants.

AbstractA widely used indicator for cultural class is strongly related to a lower body mass index (BMI): cultural capital measured as ‘highbrow' taste. This study’s objective was to theorise and measure aspects of cultural class that are more plausibly linked to low BMI, and subsequently explore their relevance. Building on Bourdieusian theory we derive four of those aspects: ‘refinement’ (valuing form and appearance over function and substance), ‘asceticism’ (self‐imposed constraints), ‘diversity’ (appreciation of variety in and of itself) and ‘reflexivity’ (reflexive deliberation and internal dialogue). Using standardised interviews with 597 participants in the Dutch GLOBE study in 2016, we subsequently demonstrate: (i) newly developed survey items can reliably measure four aspects of cultural class: ‘asceticism’, ‘general refinement’, ‘food refinement’ and ‘reflexivity’ (Cronbach’s alphas between 0.67–0.77); (ii) embodied/objectified cultural capital (i.e. ‘highbrow’ taste) was positively associated with general refinement, food refinement and reflexivity, whereas institutionalised cultural capital (i.e. education) was positively associated with asceticism and reflexivity; (iii) asceticism, general refinement, reflexivity, but not food refinement, were associated with a lower BMI; (iv) asceticism, general refinement and reflexivity together accounted for 52% of the association between embodied/objectified cultural capital and BMI, and 38% of the association between institutionalised cultural capital and BMI.
Prelabour uterine rupture: characteristics and outcomes
Authors: Al‐Zirqi I , Vangen S 
Published: June 2020

ObjectiveTo describe the characteristics and outcomes of prelabour uterine ruptures.DesignDescriptive study based on population data from the Medical Birth Registry of Norway, the Patient Administration System and medical records.SampleMaternities with uterine rupture before start of labour in Norway during the period 1967–2008 (8 complete ruptures among 2 334 712 women with unscarred uteri, and 22 complete and 45 partial ruptures among 121 085 women with scarred uteri).MethodWe measured the rate of perinatal deaths and peripartum hysterectomy following ruptures. In addition, we studied the characteristics of ruptures.ResultsThe eight complete ruptures in women with unscarred uteri were associated with trauma from traffic accidents (n = 3; 37.5%), previous curettage (n = 3; 37.5%) and congenital uterine malformations (n = 2; 25%), resulting in seven perinatal deaths and two hysterectomies. The 22 complete ruptures in scarred uteri were mostly outside the lower uterine segment (n = 17; 72.7%). Abnormally invasive placenta (AIP) and previous rupture were present in four (18.2%) and three women (13.6%), respectively. They resulted in nine perinatal deaths (39.1%) and two hysterectomies (9.1%). The 45 partial ruptures involved mostly scars in the lower uterine segment (n = 39; 86.7%). None of them resulted in perinatal death or hysterectomy. Perinatal deaths have decreased dramatically in recent years, despite increasing prelabour rupture rates.ConclusionAlthough complete uterine ruptures before labour start were rare, they often resulted in catastrophic outcomes, such as perinatal death. Scars outside the lower segment were associated with a higher percentage of catastrophic prelabour ruptures compared with scars in the lower segment (Video S1).Tweetable abstractComplete prelabour uterine ruptures were rare, but resulted in high perinatal deaths, especially if they were in scars outside the lower segment.
