Authors: Tejedor Tejada Eduardo , De la Fuente Marcos Domiciana , Cuesta Lozano Maria Jesus , Benedí González Juana , Moro Aguado Jesús , Tejedor Muñoz Jesús Miguel 
Published: February 2021

Purpose
This study aims to assess the potency and dose of Δ-9-Tetrahidrocannabinol (THC) and Cannabidiol (CBD) in cannabis joints. This will enable better estimates of the degree of exposure in a user and contribute towards a better understanding of potential harmful effects.

Design/methodology/approach
Analysis of intact joints confiscated by law enforcement on the street in the autonomous region of Castilla y León (Spain) during the years 2017–2019.

Findings
This study analysed THC, CBN and CBD in marijuana joints (N = 744). Joints contain cannabis and tobacco (N = 729), had a median net weight 0.69 g (IQR = 0.28); concentration THC median was 6.30%(IQR = 4.51) and THC median dose 42 mg (IQR = 32.75). A total of 35.5% mixed joints contained CBN – median percentage 0.61% (IQR = 0.51). CBD was detected 10.3% of mixed joints – median percentage 0.13% (IQR = 0.12) and median dose 1 mg (IQR = 0.92). CBD/THC ratio presented median value of 0.02 (IQR = 0.02). The samples analysed comprised pure cannabis joints (N = 15), with THC median 11.86% (IWR = 6.30) or median dose of 118 mg.

Originality/value
The study found high values for concentration and dose of THC and CBD in cannabis joints, warning of high exposures for the user and associated potential consequences. The results obtained contribute new perspectives on the definition of a standard cannabis unit.
Learning styles in the digital library and their application in academic communities in the biomedical and health areas
Authors: Méndez-Govea Silvia , Mireles-Cárdenas Celia , Tarango Javier 
Published: February 2021

Purpose
This paper aims to confirm the importance of developing knowledge, skills and attitudes in the permanent use of digital scientific information, which complements the training of professionals in the biomedical and health areas, considering that this type of user communities require up-to-date and truthful information for future decision-making which will directly affect the health of patients.

Design/methodology/approach
The study started from the elaboration of a diagnosis on learning styles in a student community at the undergraduate level in the area of biomedical and health sciences of the Autonomous University of San Luis Potosí (Mexico) (UASLP), through the application of the Honey-Alonso Learning Styles questionnaire (CHAEA), and by using such results it was possible to derive learning strategies for the achievement of digital information competencies that were effective in practice.

Findings
According to the diagnostic results, the learning styles with the greatest presence in students in the area of Biomedical and Health Sciences were identified and from this, precise didactic strategies were derived to enhance information skills in the use of digital sources. For this case, the Big6 Model was used and its implementation was combined (face-to-face and virtual) in the academic community studied, integrating an information skills development program in the digital library of the Center for Information in Biomedical Sciences (CICBI) from the university itself.

Originality/value
A practical experience is presented, which also offered concrete solutions, based on particular characteristics of the users. There is a low presence of studies of digital libraries’ users that consider aspects related to learning styles, especially applied from the perspective of information sciences and the digital library.
Optimum design of composite structures with ply drop-offs using response surface methodology
Authors: Diniz Camila Aparecida , Méndez Yohan , de Almeida Fabrício Alves , da Cunha Jr Sebastião Simões , Gomes G.F. 
Published: February 2021

Purpose
Many studies only take into account the ply stacking sequence as the design variable to determine the optimal ply drop-off location; however, it is necessary to optimize other parameters that have a direct influence on the ply drop-off site such as which plies should be dropped and in which longitudinal direction. That way, the purpose of this study is to find the most significant design variables relative to the drop-off location considering the transversal and longitudinal positions, seeking to achieve the optimal combination of ply drop-off locations that provides excellent performance for the laminate plate.

Design/methodology/approach
This study aims to determine the optimal drop-off location in a laminate plate using the finite element method and an approach statistical with design of experiments (DOE).

Findings
The optimization strategy using DOE revealed to be satisfactory for analyzing laminate structures with ply drop-offs, demonstrating that not all design factors influence the response variability. The failure criterion response variable revealed a poor fit, with an adjusted coefficient of determination lower than 60%, thus demonstrating that the response did not vary with the ply drop-off location. Already the strain and natural frequency response variables presented high significance. Finally, the optimization strategy revealed that the optimal drop-off location that minimizes the strain and maximizes the natural frequency is the ply drop-off located of the end plate.

Originality/value
It was also noted that many researchers prefer evolutionary algorithms for optimizing composite structures with ply drop-offs, being scarce to the literature studies involving optimization strategies using response surface methodology. In addition, many studies only take into account the ply stacking sequence as the design variable to determine the optimal ply drop-off location; however, in this study, the authors investigated other important parameters that have direct influence on the ply drop-off site such as which plies should be dropped and in which longitudinal direction.
A numerical method of lower bound dynamic shakedown analysis for 3D structures
Authors: Zhang Guichen , Peng Heng , Zhang Hongtao , Tang Juzhen , Liu Yinghua 
Published: February 2021

Purpose
The safety assessment of engineering structures under repeated variable dynamic loads such as seismic and wind loads can be considered as a dynamic shakedown problem. This paper aims to extend the stress compensation method (SCM) to perform lower bound dynamic shakedown analysis of engineering structures and a double-closed-loop iterative algorithm is proposed to solve the shakedown load.

Design/methodology/approach
The construction of the dynamic load vertexes is carried out to represent the loading domain of a structure under both dynamic and quasi-static load. The SCM is extended to perform lower bound dynamic shakedown analysis of engineering structures, which constructs the self-equilibrium stress field by a series of direct iteration computations. The self-equilibrium stress field is not only related to the amplitude of the repeated variable load but also related to its frequency. A novel double-closed-loop iterative algorithm is presented to calculate the dynamic shakedown load multiplier. The inner-loop iteration is to construct the self-equilibrated residual stress field based on the certain shakedown load multiplier. The outer-loop iteration is to update the dynamic shakedown load multiplier. With different combinations of dynamic load vertexes, a dynamic shakedown load domain could be obtained.

Findings
Three-dimensional examples are presented to verify the applicability and accuracy of the SCM in dynamic shakedown analysis. The example of cantilever beam under harmonic dynamic load with different frequency shows the validity of the dynamic load vertex construction method. The shakedown domain of the elbow structure varies with the frequency under the dynamic approach. When the frequency is around the resonance frequency of the structure, the area of shakedown domain would be significantly reduced.

Research limitations/implications
In this study, the dynamical response of structure is treated as perfect elastoplastic. The current analysis does not account for effects such as large deformation, stochastic external load and nonlinear vibration conditions which will inevitably be encountered and affect the load capacity.

Originality/value
This study provides a direct method for the dynamical shakedown analysis of engineering structures under repeated variable dynamic load.
Understanding how social responsibility drives social innovation: characteristics of radically innovative projects
Authors: Turker Duygu , Ozmen Y. Serkan 
Published: February 2021

PurposeThis study aims to analyze how corporate social responsibility (CSR) initiatives address sustainability challenges by focusing on the congruence between process and outcome variables of CSR.Design/methodology/approachFollowing a theory-driven model, a content analysis was conducted on 63 award-winning social responsibility projects.FindingsThe study reveals that the adoption of a proactive approach during environmental assessment, which manifests itself in a focus on emerging sustainability challenges with a deeper interest, affects the centrality of social responsibility initiative by increasing its learning and partnership potential and leads organizations to produce radical innovations.Practical implicationsThe findings provide a valuable understanding for practitioners on organizing the decision making process of CSR initiatives in order to unlock its learning potentials.Social implicationsRadically innovative projects with their higher levels of proactivity, centrality and generalizability are better than incremental ones at transferring and integrating company resources and capabilities to address emergent sustainability challenges.Originality/valueThe impact of CSR on society and nature has been a neglected area of literature. To reduce this gap, this study analyzes how the configuration of process variables shapes the outcomes of socially responsible initiatives on sustainability. It also provides a new typology on the relevance of CSR initiatives to company mission/model that can show how CSR can unlock organizational learning and innovation potentials.
Well-being in times of ill-being: how AMO HRM practices improve organizational citizenship behaviour through work-related well-being and service leadership
Authors: Salas-Vallina Andres , Pasamar Susana , Donate Mario J. 
Published: February 2021

PurposeThe purpose of this research is to examine the effect of ability, motivation and opportunity (AMO) practices on organizational citizenship behaviour (OCB), in medical staff working in specialized units. In addition, we check the mediating role of work-related well-being, understood as engagement, trust and exhaustion, in the relationship between AMO practices and OCB. Furthermore, the moderating role of service leadership is analysed in the relationship between AMO practices and work-related well-being.Design/methodology/approachUsing the AMO framework under the job demands-resources (JD-R) model, and based on a sample of 214 employees from public healthcare, a time-lagged moderation-mediation model was performed.FindingsResults provide evidence that AMO practices have a positive effect on OCB. Further, work-related well-being mediated the effect of AMO practices on OCB. In addition, service leadership exerted a moderating role between AMO practices and work-related well-being.Originality/valueBuilding on recent research which has emphasized the knowledge gap regarding how human resource practices might positively affect both employees and organizations, this is the first study that indicates that said practices positively affect both employee well-being and OCBs in the public healthcare context.
Human capital neurodiversity: an examination of stereotype threat anticipation
Authors: Priscott Tamsin , Allen Robert Anthony 
Published: February 2021

PurposeThe purpose of the study was to test the assumption of similarities between neurodivergents and other minority groups regarding their reaction to stereotype threat. In addition, it aimed to identify the source of stereotype threat and the neurodivergent's response to it.Design/methodology/approachTwo studies were conducted. Study 1 employed three exercises consisting of brochures, learning sets and posters to test organisational cues, notions of intelligence and situational cues. It collected data from 53 participants to establish whether stereotype threat observed in visible difference such as race, gender and intelligence is equally relevant to neurodiversity. Study 2 consisted of interviews with 44 participants to establish stereotype threat source, reaction and effect on declaration of invisible difference.FindingsNeurodivergents, defined by their invisible difference, react similarly to those with a visible difference with respect to organisational cues and stereotype threat. They will cognisantly define their behaviours depending upon those cues and stereotype threat. In doing so, they draw upon previous personal and work experiences. After the event, they will make a comparison to their assessment. If it is similar to their assessment, it reinforces it; however, if it is dissimilar, the neurodivergent will make an adjustment to the assessment. In both cases, the experience will form part of a future threat assessment.Research limitations/implicationsThe research is limited by its interpretivist nature and sample comprising personnel within a UK government organisation.Practical implicationsThe research has practical implications for employers, providing managers with a model to understand the impact a neurodivergents' previous experiences can have on their ability to interact within the workplace. Such understanding can provide insight into how best to utilise human capital.Originality/valueThis study makes a contribution to theory by expanding knowledge of neurodiversity in the workplace and by identifying the neurodivergents' reaction to the anticipation of a stereotype threat. In addition, it offers the stereotype threat anticipation conceptual model as a representation of the cognitive decisions made by neurodivergents to conceal or reveal their invisible difference.
Postgraduate students' experiences and perspectives on transformation of teaching and learning in tertiary education
Authors: David Solomon Arulraj , Hill Christopher 
Published: February 2021

PurposeTertiary education has been going through dramatic transformation in recent times. Such transformation is seen in teaching and learning at tertiary education. This study, therefore, aims to understand the transformation of teaching and learning in tertiary-level education, particularly by accounting the experiences and perspectives of postgraduate learners.Design/methodology/approachThe study narrowed higher education transformation into four key drivers such as expansion, excellence, extension, external and explored their dynamics and impacts for teaching and learning in tertiary education. The data was gathered from 25 doctoral students from three different cohorts, who shared their critical reflection on their experiences and perspectives on the transformation of teaching and learning in a reflective journal. The 25 reflective journals were used as the qualitative transcripts for analysis. Standard required ethical protocols were followed in the research. The results were analysed using thematic analysis.FindingsThe findings indicate that teaching and learning in the higher education are transformed largely using technology, by engaging various stakeholders, several pedagogic methods, a range of assessments and numerous contents and materials. The findings suggest that higher education transformation has affected teaching and learning in tertiary education positively in the UAE, while identifying some relevant areas for improvement.Research limitations/implicationsSingle data and small sample size (although suitable for the study) are the limitations. The experiences and perspectives of the postgraduate scholars on teaching and learning offer relevant insights for postgraduate learners, academic, researchers, curriculum developers, policymakers. The study asserts that accounting student's experiences and perspectives supports the understanding on the transformation of teaching and learning in tertiary education.Originality/valueThe study contributes to the ongoing debate on how students are helping shape teaching and learning practices in tertiary education, particularly from the UAE context using informed critical reflection. The study contends and concludes that teaching and learning in tertiary education are continued to be shaped by emerging trends and development.
Research evaluation of computer science publications using Altmetrics: a cohort study of Indian Central Universities
Authors: Lamba Manika , Kashyap Neha , Margam Madhusudhan 
Published: February 2021

PurposeSocial interaction applications and reference tools are actively used by researchers to share and manage their research publications. Thus, this paper aims to determine the scholarly impact of selected Indian central universities.Design/methodology/approachThis study analyzed 669 articles having both Dimensions citations and Altmetric attention scores published by 35 Indian central universities for 4 subfields of Computer Science using Altmetric Explorer. This paper determined each university’s contribution in the studied subfields of Computer Science and the correlation among Altmetric attention score (aggregated and individual), Dimensions citation, and Mendeley readership counts for all 669 articles and stratified percentile sets of top 25%, and top 50% of the overall number of articles.FindingsThe findings showed that Jawaharlal Nehru University had the maximum Altmetric attention score, Banaras Hindu University received the maximum Dimensions citation, and University of Hyderabad (UoH) received the maximum number of Mendeley readers. Each central university was examined individually and then ranked based on their median values of Dimensions citations and Altmetric attention scores. Further, Twitter had the maximum Altmetric coverage, followed by Google+, Patent and Facebook for the retrieved articles. A significant strong positive correlation was observed between the Dimensions citation and Mendeley readership counts for all the three categories.Research limitations/implicationsBoth Altmetric attention scores and Dimensions citations can help funding agencies to assess and evaluate the research productivity of these universities, thus, making important decisions such as increasing, decreasing, re-distributing their funds.Originality/valueThe current body of research is focused mostly on relationships between citations and individual Altmetric indicators predominantly. For most of the studies, the citations were retrieved from Scopus, Web of Science or Google Scholar database. It was observed that by far, no study had examined the relationship between citations retrieved from Dimensions database, Altmetrics scores (both aggregated and individual) and Mendeley readership counts.
Ontology, sovereignty, legitimacy: two key moments when history curriculum was challenged in public discourse and the curricular effects, Australia 1950s and 2000s
Authors: Keynes Matthew R. , Marsden Beth 
Published: February 2021

PurposeThe purpose of this paper is to examine the ways that history curriculum has worked to legitimise dispossession through narratives that elide questions of Indigenous sovereignty, and which construct and consolidate white settler identity and possession.Design/methodology/approachThe paper uses two case studies to compare history education documentation and materials at key moments where dominant narratives of settler legitimacy were challenged in public discourse: (1) the post-war humanitarian agenda of fostering “international understanding” and; (2) the release and educational recommendations of the 1997 Bringing them Home Report.FindingsThe paper shows that in two moments where narratives of settler legitimacy were challenged in public discourse, the legitimacy of settler possession was reiterated in history curricula in various ways.Practical implicationsThis research suggests that the prevailing constructivist framework for history education has not sufficiently challenged criticisms of the representation of Aboriginal history and the history of settler-colonialism in the history syllabus.Originality/valueThe paper introduces two case studies of history curriculum and shows how, in different but resonant ways, curricular reforms worked to bolster the liberal credentials of the settler state.
The homotopy perturbation method for fractional differential equations: part 1 Mohand transform
Authors: Nadeem Muhammad , He Ji-Huan , Islam Asad 
Published: February 2021

Purpose
This study aims that very lately, Mohand transform is introduced to solve the ordinary and partial differential equations (PDEs). In this paper, the authors modify this transformation and associate it with a further analytical method called homotopy perturbation method (HPM) for the fractional view of Newell–Whitehead–Segel equation (NWSE). As Mohand transform is restricted to linear obstacles only, as a consequence, HPM is used to crack the nonlinear terms arising in the illustrated problems. The fractional derivatives are taken into the Caputo sense.

Design/methodology/approach
The specific objective of this study is to examine the problem which performs an efficient role in the form of stripe orders of two dimensional systems. The authors achieve the multiple behaviors and properties of fractional NWSE with different positive integers.

Findings
The main finding of this paper is to analyze the fractional view of NWSE. The obtain results perform very good in agreement with exact solution. The authors show that this strategy is absolutely very easy and smooth and have no assumption for the constriction of this approach.

Research limitations/implications
This paper invokes these two main inspirations: first, Mohand transform is associated with HPM, secondly, fractional view of NWSE with different positive integers.

Practical implications
In this paper, the graph of approximate solution has the excellent promise with the graphs of exact solutions.

Social implications
This paper presents valuable technique for handling the fractional PDEs without involving any restrictions or hypothesis.

Originality/value
The authors discuss the fractional view of NWSE by a Mohand transform. The work of the present paper is original and advanced. Significantly, to the best of the authors’ knowledge, no such work has yet been published in the literature.
