Network resource mobilisation limitations and the alliance portfolio network
Authors: Bolivar Luis Miguel , Castro-Abancéns Ignacio , Casanueva Cristóbal , Gallego Angeles 
Published: March 2021

PurposeThe purpose of this study is to examine how access and mobilisation of network resources influence a firm's performance. It has been established that alliance portfolio (AP) network parameters shape the access to network resources; however, resource access understood as value creation differs from resource mobilisation understood as value capture. Hence, the paper contributes towards the comprehension of AP performance by examining the extent to which a firm's level of network resource mobilisation (NRM) plays a role in improving financial performance and how this strategy conditions the benefits obtained from a firm's AP.Design/methodology/approachThis study employs an interorganisational network approach to describe the APs of firms; subsequently, it examines how AP network parameters and resource mobilisation determine financial performance. To this end, sequential multiple regression models are applied to a sample from the Top International Airlines database, covering 135 portfolios that correspond to 1117 codeshare partnerships.FindingsThe analyses show that the NRM level has an invertedU-shaped relationship with revenue performance, thereby revealing the limitations and considerations in the strategic alliance strategy. In addition, the authors show how the resource mobilisation decision moderates the faculty of AP parameters to influence a firm's financial performance, thereby exposing the nuanced relationship between AP size, diversity and redundancy. The findings convey strategic and practical implications for managers regarding how to capture value from their APs.Practical implicationsThe findings suggest the need for NRM to form part of a firm's AP management capability, so that, by acquiring superior strategic knowledge in NRM, the firm is able to extract value from its AP through the optimal exploitation of complementary assets.Originality/valuePrevious research has highlighted the multidimensional nature of APs at the theoretical level; however, no simultaneous empirical analysis of various AP parameters has yet been produced. The research empirically analyses an AP network and how its parameters affect financial performance in the presence of a resource mobilisation strategy. Not only do the authors introduce the analysis of the curvilinear relationship between the level of NRM and a firm's performance, but also of its role in advancing the AP literature.
Administrative risks challenging the adoption of smart contracts in construction projects

Published: March 2021

PurposeAs a remedy to usually voluminous, complicated and not easily readable construction contracts, smart contracts can be considered as an effective and alternative solution. However, the construction industry is merely known as a frontrunner for fast adoption of recent technological advancements. Numerous administrative risks challenge construction companies to implement smart contracts. To highlight this issue, this study aims to assess the administrative risks of smart contract adoption in construction projects.Design/methodology/approachA literature survey is conducted to specify administrative risks of smart contracts followed by a pilot study to ensure that the framework is suitable to the research question. The criteria weights are calculated through the fuzzy analytical hierarchy process method, followed by a sensitivity analysis based on degree of fuzziness, which supports the robustness of the developed hierarchy and stability of the results. Then, a focus group discussion (FGD) is performed to discuss the mitigation strategies for the top-level risks in each risk category.FindingsThe final framework consists of 27 sub-criteria, which are categorized under five main criteria, namely, contractual, cultural, managerial, planning and relational. The findings show that (1) regulation change, (2) lack of a driving force, (3) works not accounted in planning, (4) shortcomings of current legal arrangements and (5) lack of dispute resolution mechanism are the top five risks challenging the adoption of smart contracts in construction projects. Risk mitigation strategies based on FGD show that improvements for the semi-automated smart contract drafting are considered more practicable compared to full automation.Originality/valueThe literature is limited in terms of the adoption of smart contracts, while the topic is receiving more attention recently. To support easy prevalence of smart contracts, this study attempts the most challenging aspects of smart contract adoption.
The impact of COVID-19 pandemic concerns and gender on mentor seeking behavior and self-efficacy
Authors: van Esch Chantal , Luse William , Bonner Robert L. 
Published: March 2021

PurposeThis study examined the effects of gender and pandemic concerns on mentorship seeking behavior during the pandemic caused by the coronavirus disease (COVID-19) and its relationship to self-efficacy.Design/methodology/approachThis study analyzes the data collected from 253 academics in a quantitative survey administered online.FindingsWomen and those with higher levels of concern about the COVID-19 pandemic were more likely to seek mentorship. During this time of uncertainty role modeling was sought more than career support and psychosocial support. All three functions of mentorship seeking were positively associated with higher levels of self-efficacy.Research limitations/implicationsThe present study finds that individuals turn to mentors when they are concerned about macro-level events (e.g. a global pandemic). Additionally, individuals who self-identify as women sought mentorship to a greater extent than men. In this way, it is not only the situation that matters (like women having fewer resources and more demands than men) but also the perception of a situation (like how concerned individuals were about the COVID-19 pandemic). Additionally, this paper helps to further develop the understanding of the mentorship function of role modeling.Practical implicationsOrganizations and mentors ought to be cognizant of role modeling during times of crisis, especially for women, this may be counterintuitive to the inclination to provide career and psychosocial support for mentees.Originality/valueThis study examines the gendered implications for mentoring during the COVID-19 pandemic. This study specifically examines mentorship seeking behavior and its influence on self-efficacy during uncertain times.
ISO 21500 and success management: an integrated model for project management
Authors: Takagi Nilton , Varajão João 
Published: March 2021

PurposeProjects are one of the main ways used to develop organisations and turn their strategic initiatives into a reality. To support project management, several entities (e.g. associations, institutes, etc.) provide standards, guides and project management methodologies. However, despite its wide coverage of project management knowledge areas, standards currently have no specific processes focused on planning and evaluating success. The absence of these processes can limit the vision of managers and their teams on what most contributes to the success of a project. Aiming at contributing to fill this gap, this paper proposes the integration of success management processes in the ISO 21500 standard.Design/methodology/approachTo develop the integration model, a Design Science Research approach was adopted for the construction and evaluation of the resulting artefact.FindingsThe result is an integrated model and insights for its application in practice. The model aims to help managers and their teams to identify which success management activities need to carry out and how to integrate them with the other processes of the ISO 21500 standard.Research limitations/implicationsThe integrated model was applied in only one project. Another limitation is the difficulty in comparing the results obtained due to the small number of works focused on success management (namely related to planning, measuring, controlling and reporting success in practice) and its integration with project management standards, guides and methodologies.Originality/valueThe integrated model, based on success management and the ISO 21500 standard, is an important and original contribution to understand and achieve success in projects. This promotes a new vision of balanced management, directing the management effort to the areas that effectively contribute to success in each project.
Construction disability management maturity model: case study within the Manitoban construction industry
Authors: Quaigrain Rhoda Ansah , Issa Mohamed Hassan 
Published: March 2021

PurposeA review of the literature revealed a lack of coherent frameworks for implementing disability management, particularly within the construction industry. This study involved developing the construction disability management maturity model (CDM3) to assess the maturity of disability management (DM) practices in construction organisations.Design/methodology/approachIn its current form, the model assessed twelve indicators using a series of questions representing relevant best practices for each indicator and five different maturity levels. An analytical hierarchical process was conducted using eight construction and DM experts to determine the weights of importance of these different indicators. The model was then applied to evaluate ten construction companies in Manitoba, Canada.FindingsThe results revealed that the indicators of “Return to Work”, “Disability and Injury Prevention”, and “Senior Management Support” practises were the most heavily weighted and, thus, the most important. Companies' DM performance was observed, on average, to be at the quantitatively managed level. “Senior Management Support” and “Disability Injury Prevention” practices were observed to be the most mature indicators on average, revealing a potential relationship between the most important and most mature indicators.Research limitations/implicationsThe sample size of companies evaluated is a key limitation in that it does not permit for the generalisation of the results.Practical implicationsThis study provided a framework for benchmarking the DM performance of construction organisations.Originality/valueNo similar maturity model has been developed to date to assess DM in construction, making the CDM3 the first of its kind to evaluate a construction organisation's existing DM practices against best practises.
Regulating corporate social responsibility practices of adopting codes of conduct through criminal law
Authors: Litor Lilach 
Published: March 2021

PurposeThis paper explores different approaches to regulating corporate social responsibility (CSR) patterns of adopting codes of conduct, and discusses the approach that courts should embrace.Design/methodology/approachCase studies from various legal systems will be examined. The paper presents new typology relating to different patterns of the Corporate Social Performance (CSP) model, based on aspects of the CSR pyramid, namely, legislative CSR and ethical CSR. Legislative CSR includes adoption of thin codes which reflect compliance within current legal standards of the criminal code, while ethical CSR includes codes reflecting ethical norms and corporate social citizenship beyond mere compliance. The paper also includes the interplay of different patterns of CSR and three approaches to regulation regarding these patterns.FindingsBoth the Israeli negative CSR regulatory approach and the American legislative CSR regulatory approach present difficulties.Originality/valueThe paper introduces a theory for regulating CSR within criminal law, drawing on the pyramid of CSR. It presents an original discussion of distinct approaches to regulation of corporate liability, while further developing the institutional theory of CSR and the interplay of regulation and CSR. The paper suggests a novel solution regarding the regulation and acceptance of CSR: the granting of protection from criminal liability to corporations who adopt CSR.
After-sales services, brand equity and purchasing intention to buy second-hand product
Authors: Habib Muhammad Danish , Sarwar Muhammad Arslan 
Published: March 2021

Purpose
This study aims to examine the concept of brand equity and willingness to buy second-hand products in the automobile context. The customer-based brand equity model is used as a theoretical lens to examine after-sales services, brand credibility and brand loyalty as drivers of brand equity and willingness to buy the second-hand product.

Design/methodology/approach
A survey questionnaire based on convenience sampling is used to collect the data from the car owners. A total of 433 survey responses were used to empirically test the measures and propositions by using structural equation modeling (SEM).

Findings
The findings suggest that after-sales services are a key factor in developing brand credibility and brand loyalty. Results are also in support of the positive and significant impact of brand credibility and brand loyalty on brand equity and willingness to buy second-hand products.

Originality/value
Brand equity represents a differential response and preference to marketing efforts that a product obtains as a result of its brand identification. Although practitioners are actively engaged to position themselves as a unique, attractive and strong brand, little is known about the equity of the brand in the case of second-hand products. This study provides an alternate branding view to the academic scholars and to the marketing manager as this study explicitly probes into the effect of after-sales services in developing brand credibility, brand loyalty, brand equity and wiliness to buy second-hand product as an outcome.
The impact of using proportional representation system on the fragmentation of the party system in Algeria. Applied to the elections of the National People’s Assembly (1997–2017)
Authors: Mahgoub Ali Mahmoud 
Published: March 2021

PurposeThe purpose of this study is to examine the impact of using proportional representation system on the fragmentation of the party system in the Algerian political system within the period from 1997 to 2017, in which Algeria has experienced five legislative elections regularly every five years by testing a hypothesis about adopting the proportional representation system on the basis of the closed list during the foregoing legislative elections has obviously influenced the exacerbation of the Algerian party system’s fragmentation, compared to other factors.Design/methodology/approachThe essence of the theoretical framework of this study is to address the effect of the electoral system as an independent variable on the party system as a dependent variable. The starting point for that framework is to reassess the “Duverger’s law,” which appeared since the early 1950s and has influenced the foregoing relationship, and then to review the literature on a new phase that tried to provide a more accurate mechanism for determining the number of parties and their relative weight, whether in terms of electoral votes or parliamentary seats. This means that researchers began to use a measure called the effective number of parties (ENP) for Laakso and Taagepera since 1979. The study elaborates the general concepts of the electoral system and the party system. It used Laakso, Taagepera index of the “ENP” to measure the phenomenon of fragmentation party during the five legislative elections from 1997 to 2017 in Algeria.FindingsThe results of the study reveal that the proportional representation electoral system – beside other factors – had clear impacts on the fragmentation of the Algerian party system by all standards, whether on the level of the apparent rise in the number of the parties represented in the Algerian parliament from 10 parties in 1997 election to 36 parties in 2017 election or according to the index of Laakso and Taagepera (ENP). The average number of effective number of electoral parties in the five elections was around 7.66, and the average number of effective number of parliamentary parties in the five elections was around 4.39, which puts Algeria in an advanced degree of the fragmentation of the party system.Originality/valueThis study about the phenomenon of the fragmentation of the party system, which is one of the new subjects in the field of comparative politics – globally and in the Arab world. Hence, the value of this study aims to shed light on this mysterious area of science, the fragmentation of the party system in the Algerian political system during the period from 1997 to 2017.
Energy pathways modulate the resilience of stream invertebrate communities to drought

Abstract

While climate change is altering ecosystems on a global scale, not all ecosystems are responding in the same way. The resilience of ecological communities may depend on whether food webs are producer‐ or detritus‐based (i.e. ‘green’ or ‘brown’ food webs, respectively), or both (i.e. ‘multi‐channel’ food web).

Food web theory suggests that the presence of multiple energy pathways can enhance community stability and resilience and may modulate the responses of ecological communities to disturbances such as climate change. Despite important advances in food web theory, few studies have empirically investigated the resilience of ecological communities to climate change stressors in ecosystems with different primary energy channels.

We conducted a factorial experiment using outdoor stream mesocosms to investigate the independent and interactive effects of warming and drought on invertebrate communities in food webs with different energy channel configurations. Warming had little effect on invertebrates, but stream drying negatively impacted total invertebrate abundance, biomass, richness and diversity.

Although resistance to drying did not differ among energy channel treatments, recovery and overall resilience were higher in green mesocosms than in mixed and brown mesocosms. Resilience to drying also varied widely among taxa, with larger predatory taxa exhibiting lower resilience.

Our results suggest that the effects of drought on stream communities may vary regionally and depend on whether food webs are fuelled by autochthonous or allochthonous basal resources. Communities inhabiting streams with large amounts of organic matter and more complex substrates that provide refugia may be more resilient to the loss of surface water than communities inhabiting streams with simpler, more homogeneous substrates.
Contrast‐enhanced ultrasound assessed renal microvascular perfusion may predict postoperative renal complications following colorectal surgery

Published: March 2021

AbstractColorectal surgery is associated with an above‐average mortality rate of approximately 15%. During surgery, maintenance of vital organ perfusion is essential in order to reduce postoperative mortality and morbidity, with renal perfusion of particular importance. Oesophageal Doppler monitors (ODM) are commonly used to try and provide accurate measures of fluid depletion during surgery; however, it is unclear to what extent they reflect organ perfusion. In addition, it is not known whether macro‐ and/ or microvascular perfusion indices are associated with renal complications following colorectal surgery. Thirty‐two participants scheduled for colorectal surgery had three measures of macro‐ and microvascular renal blood flow via contrast enhanced ultrasound (CEUS), and simultaneous measures of cardiac output indices via ODM: (i) pre‐operatively; (ii) intra‐operatively at the mid‐point of operation, and (iii) after the conclusion of surgery. The Postoperative Morbidity Survey (POMS) was used to assess postoperative complications. Intra‐operatively, there was a significant correlation between renal microvascular flow (RT) and renal macrovascular flow (TTI) (ρ = 0.52; p = 0.003). Intra‐operative TTI, but not RT, was associated with cardiac index (ρ = −0.50; p=0.0003). Intra‐operative RT predicted increases in renal complications (OR 1.46; 95% CI 1.03–2.09) with good discrimination (C‐statistic, 0.85). Complications were not predicted by TTI or ODM‐derived indices. There was no relationship between RT and TTI before or after surgery. ODM measures of haemodynamic status do not correlate with renal microvascular blood flow, and as such are likely not suitable to determine vital organ perfusion. Only CEUS‐derived measures of microvascular perfusion were predictive of postoperative renal complications.
Time‐course in attractiveness of pheromone lure on the smaller tea tortrix moth: A generalized additive mixed model approach
Authors: Sudo Masaaki , Sato Yasushi , Yorozuya Hiroshi 
Published: March 2021

AbstractLong‐term pest insect monitoring in agriculture and forestry has advanced population ecology. However, the discontinuation of research materials such as pheromone lure products jeopardizes data collection continuity, which constrains the utilization of the industrial datasets in ecology. Three pheromone lures against the smaller tea tortrix moth Adoxophyes honmai Yasuda (Lepidoptera; Tortricidae) were available but one was recently discontinued. Hence, a statistical method is required to convert data among records of moths captured with different lures. We developed several generalized additive mixed models (GAMM) separating temporal fluctuation in the background male density during trapping and attenuation of lure attractiveness due to aging or air exposure after settlement. We collected multisite trap data over four moth generations. The lures in each of these were unsealed at different times before trap settlement. We used cross‐validation to select the model with the best generalization performance. The preferred GAMM had nonlinear density fluctuation terms and lure attractiveness decreased exponentially after unsealing. The attenuation rates varied among lures. A light trap dataset near the pheromone traps was a candidate for a male density predictor. Nevertheless, there was only a weak correlation between trap yields, suggesting the difficulty of data conversion between the traps differing in attraction mechanisms.
The health effects of wage setting institutions: How collective bargaining improves health but not because it reduces inequality
Authors: Reeves Aaron 
Published: March 2021

AbstractDo wage‐setting institutions, such as collective bargaining, improve health and, if so, is this because they reduce income inequality? Wage‐setting institutions are often assumed to improve health because they increase earnings and reduce inequality and yet, while individual‐level studies suggest higher earnings improve well being, the direct effects of these institutions on mortality remains unclear. This paper explores both the relationship between wage‐setting institutions and mortality rates whether income inequality mediates this relationship. Using 50 years of data from 22 high‐income countries (n ~ 825), I find mortality rates are lower in countries with collective bargaining compared to places with little or no wage protection. While wage‐setting institutions may reduce economic inequality, these institutions do not appear to improve health because they reduce inequality. Instead, collective bargaining improves health, in part, because they increase average wage growth. The political and economic drivers of inequality may not, then, be correlated with health outcomes, and, as a result, health scholars need to develop more nuanced theories of the political economy of health that are separate from but in dialogue with the political economy of inequality.
