Influence of elevated temperature on alkali-activated ground granulated blast furnace slag concrete
Authors: Kumar Virendra , Kumar Amit , Prasad Brajkishor 
Published: January 2020

Purpose
This paper aims to present an experimental investigation on the performances of alkali-activated slag (AAS) concrete and Portland slag cement (PSC) concrete under the influence of elevated temperature. In the present study, the alkali-activated binder contains 85% of ground granulated blast furnace slag (GGBFS) and 15% of powder blended as chemical activators.

Design/methodology/approach
For the purpose, standard size of cube, cylinder and prism have been cast for a designed mix of concrete. The AAS concrete specimens were kept for water as well as air curing. After attaining the maturity of 28 days, the samples were first exposed to different elevated temperatures, i.e. 100°C, 200°C, 300°C, 400°C, 500°C, 600°C, 700°C and 800°C. Later on, the tests were conducted on these samples to find the change in weight and the residual strength of the concrete.

Findings
After 500°C exposure, a considerable amount of the strength loss has been observed for AAS concrete. It has been evaluated that the performance of AAS concrete is better than that of the PSC concrete at elevated temperature.

Research limitations/implications
The present research work is being applied on the material for which the experimental result has been obtained.

Practical implications
The author has tried to develop a new type of binder by using steel industry waste material and then tested at elevated temperature to sustain at high temperatures.

Social implications
This research may give a social impact for developing mass housing project with a lower cost than that of using a conventional binder, i.e. cement.

Originality/value
A new type of binder material is being developed.
Can senior management sustain engagement and identification to support learning? Designing communities and defining goals
Authors: Macpherson Allan , Kiersch Christa , Antonacopoulou Elena 
Published: January 2020

Purpose
The purpose of this paper is to explore the premise that organizationally defined communities of practice can be a valuable strategic learning tool for management.

Design/methodology/approach
It is a quantitative study in a single organization. The authors analyzed data from 1,082 employees using hierarchical (multi-level) linear modeling.

Findings
Management can support learning and influence engagement and identification by defining communities of practice and establishing goals, but this is not always successful. Engagement may be a short-term phenomenon, dependent significantly on the type of practice or project in which community members are allowed or decide, to participate. Identification, on the other hand, may need practices that support longer-term individual development aims allowing and supporting the achievement of personal ambition or competence.

Research limitations/implications
Future studies of organizationally defined communities of practice could use established scales to measure leadership, engagement and identification.

Practical implications
When implementing this type of organizationally defined community of practice, attention to the types of practices or projects to which the employees can contribute seems to be most important.

Originality/value
The authors show that: the dynamics within communities of practice (CoP) designed by top management teams have an impact on CoP members’ identification and engagement; organizationally defined CoP may be part of a broader landscape of professional practice (LoP); engagement, objectives and practices, and not only identification and knowledgeability, are key to the dynamics of CoP and LoP; senior management’s leadership role in setting up successful CoP is equivocal.

Published: January 2020

PurposeThe purpose of this paper is to explore the perceptions of women working in the commercial real estate industry to assess how they approach mentoring relationships and take steps to maximize the value derived therefrom.Design/methodology/approachThrough thematic analysis of 39 interviews conducted with women serving as local chapter presidents of CREW Network, the paper offers insights as to how women position themselves to receive mentorship throughout their careers and engage with mentors to address their evolving needs. In particular, three themes of commitment, reciprocity in the mentoring relationship and mentee motivation emerged.FindingsThe results suggest that this is a strategic process and one in which many women are proactively engaging to ascend to leadership positions in the corporate world. While the study is limited to those working in commercial real estate, clear implications exist for other industries.Originality/valueBy identifying and exploring these themes, the paper serves as a starting point for future research considering how women inside and outside of the commercial real estate industry can more strategically pursue mentorship and use it to attain leadership roles.
Organizations and sustainability: a field of knowledge
Authors: Borim-de-Souza Rafael , Zanoni Beatriz Lima , Jan-Chiba Jacques Haruo Fukushigue , Borinelli Benilson 
Published: January 2020

PurposeThe purpose of this paper is to analyze the relationship between organizations and sustainability as a field of knowledge possible to be accessed by descriptive and thematic representations extracted from administration area published papers about the subject.Design/methodology/approachThis paper consists in a bibliometric study. It was considered five bases of journals indexation: AOM, Emerald, Elsevier, Sage and Wiley. By judgmental sampling, 11 journals were selected, in which, at the end of data collection, 192 papers were eligible to be analyzed by content and thematic analysis techniques.FindingsIn quantitative data analysis, it was implied that the field of knowledge identity was colonized by the Euro-American axis. In qualitative analysis, it was found that the investigated field of knowledge was built by 15 thematic representations, understood by three forms of comprehensions, enabled by four different debates.Practical implicationsIn a political and ideological perspective of sustainability, the socioenvironmental interests are silenced by a dominant power. Along these lines, the theme is managed, instrumentalized and commercialized by a dominant power. This paper aims to make these relations between organizations and sustainability public. The investigated field of knowledge houses a dominant discursive representation interest in respect to the investigated relations.Originality/valueThis paper innovates by considering conceptual frameworks of sustainable development and sustainability developed from contributions extracted from organizational theories, sociological reflections and political science orientations. The selection was necessary to ensure the theoretical viability of the discussion proposed by this paper.
Bitmap generation from computer-aided design for potential layer-quality evaluation in electron beam additive manufacturing
Authors: Wong Hay 
Published: January 2020

Purpose
Electron beam additive manufacturing (EBAM) is a popular additive manufacturing (AM) technique used by many industrial sectors. In EBAM process monitoring, data analysis is focused on information extraction directly from the raw data collected in-process, i.e. thermal/optical/electronic images, and the comparison between the collected data and the computed tomography/microscopy images generated after the EBAM process. This paper aims to postulate that a stack of bitmaps could be generated from the computer-aided design (CAD) at a range of Z heights and user-defined region of interest during file preparation of the EBAM process, and serve as a reference image set.

Design/methodology/approach
Comparison between that and the workpiece images collected during the EBAM process could then be used for quality assessment purposes. In spite of the extensive literature on CAD slicing and contour generation for AM process preparation, the method of bitmap generation from the CAD model at different field of views (FOVs) has not been disseminated in detail. This article presents a piece of custom CAD-bitmap generation software and an experiment demonstrating the application of the software alongside an electronic imaging system prototype.

Findings
Results show that the software is capable of generating binary bitmaps with user-defined Z heights, image dimensions and image FOVs from the CAD model; and can generate reference bitmaps to work with workpiece electronic images for potential pixel-to-pixel image comparison.

Originality/value
It is envisaged that this CAD-bitmap image generation ability opens up new opportunities in quality assessment for the in-process monitoring of the EBAM process.
Dimensional analysis of 3D-printed acetabular cups for hip arthroplasty using X-ray microcomputed tomography
Authors: Dall’Ava Lorenzo , Hothi Harry , Henckel Johann , Di Laura Anna , Bergiers Sean , Shearing Paul , Hart Alister 
Published: January 2020

Purpose
Three-dimensional (3D) printing is increasingly used to produce orthopaedic components for hip arthroplasty, such as acetabular cups, which show complex lattice porous structures and shapes. However, limitations on the quality of the final implants are present; thus, investigations are needed to ensure adequate quality and patients safety. X-ray microcomputed tomography (micro-CT) has been recognised to be the most suitable method to evaluate the complexity of 3D-printed parts. The purpose of this study was to assess the reliability of a micro-CT analysis method comparing it with reference systems, such as coordinate measuring machine and electron microscopy.

Design/methodology/approach
3D-printed acetabular components for hip arthroplasty (n = 2) were investigated. Dimensions related to the dense and porous regions of the samples were measured. The micro-CT scanning parameters (voltage – kV, current – µA) were optimised selecting six combinations of beam voltage and current.

Findings
Micro-CT showed good correlation and agreement with both coordinate measuring machine and scanning electron microscopy when optimal scanning parameters were selected (130 kV – 100 µA to 180 kV – 80 µA). Mean discrepancies of 50 µm (± 300) and 20 µm (± 60) were found between the techniques for dense and porous dimensions. Investigation method such as micro-CT imaging may help to better understand the impact of 3D printing manufacturing technology on the properties of orthopaedic implants.

Originality/value
The optimisation of the scanning parameters and the validation of this method with reference techniques may guide further analysis of similar orthopaedic components.

Authors: Lochab Anshu , Nath Vishnu 
Published: January 2020

Purpose
The purpose of this paper is to examine the relationship between proactive personality (PP), goal orientation (GO), meta-skills and the underlying dimensions of protean (self-directed and value-driven) and boundaryless (boundaryless mobility and mobility preference) career attitudes among Indian IT professionals.

Design/methodology/approach
Data were collected from 600 IT professionals working in six IT companies in the Delhi-NCR (National Capital Region) in India. Structural equation modeling was used to validate the measures of the selected constructs and for testing the hypothesis.

Findings
The results of the study revealed that PP significantly affects individuals’ protean and boundaryless career attitudes. Moreover, GO significantly affects protean career attitudes, and meta-skill significantly affects boundaryless mobility, respectively.

Practical implications
The study serves as a guide for the HR managers to devise the company’s strategies keeping in mind the employees’ requirements in parallel with the policies for IT industries in India.

Originality/value
The study enriches the protean and boundaryless career literature by identifying and empirically establishing the relationship between various personality traits and career patterns opted in the context of the Indian IT industry.
Professional learning and development initiatives for postdoctoral scholars
Authors: Nowell Lorelli , Ovie Glory , Kenny Natasha , Hayden K. Alix , Jacobsen Michele 
Published: January 2020

Purpose
Postdoctoral scholars are increasingly pursuing diverse career paths requiring broad skill sets. This study aims to create a more comprehensive understanding of current approaches and strategies for postdoctoral scholars professional learning and development.

Design/methodology/approach
This literature review is a systematic examination and synthesis of the current literature describing professional learning and development pertaining to postdoctoral scholars. The objectives and components of initiatives were extracted and narratively synthesized to identity important patterns and themes across the literature.

Findings
Commonalities amongst professional learning and development initiatives for postdoctoral scholars included skills development in the following areas: teaching and learning, mentorship, academic careers, academic writing, industry careers, networking, career planning, project management, time management, communication, leadership and balancing work-life demands.

Originality/value
In synthesizing the literature that describes professional learning and development opportunities for postdoctoral scholars, it is apparent that opportunities look different in every setting with no empirical evidence that one strategy is more effective than another. Given the significant resources often required to support professional learning and development initiatives, a deeper understanding of the benefits and deficiencies of various components is needed to ensure scarce resources are invested in the most effective strategies.
So tall within: sojourner truth’s long walk to freedom
Authors: Brodey Sari , Tidd La Wanda , Serriere Stephanie 
Published: January 2020

Purpose
The purpose of this paper is to support teachers in utilizing the 2019 National Council for the Social Studies (NCSS) Notable Tradebook, “Sojourner Truth’s Long Walk to Freedom” (Schmidt, 2018). The authors found this book to be useful, beautiful and well-written but with several complex and dense literary aspects. Thus, this lesson offers supports for students in decoding similes and metaphors within “juicy sentences” (Fenner and Snyder, 2017, p. 131). These tools are especially important for English language learners’ (ELLs) unlocking the meaning of a book. Through this lesson, learners are supported in understanding Schmidt’s “So Tall Within” retelling the life of an extraordinary citizen, Sojourner Truth, who worked for the enforcement of emancipation promised in the 13th amendment.

Design/methodology/approach
In this lesson, students learn to recognize similes and metaphors in texts as a tool to decode a text’s meaning. In the beginning of the lesson, students listen to a rap about Sojourner Truth’s life to initially recognize in-text similes and metaphors. Then, students apply this new skill to unlock the meaning of metaphors and similes in the “So Tall Within” book to better understand the author’s message about Sojourner’s life. Last, students each make an illustrated and written postcard to Sojourner Truth called “Walking Tall Postcards” with their given metaphor or simile and add reflections on how they do or can “walk tall.” Finally, students chronologically re-construct the postcard statements and create a class book called, “Postcards of Walking Tall.”

Findings
Students, especially ELLs, must be given supports to unlock the meaning of dense texts (Fenner and Snyder, 2017). To promote equity in the classroom, the lesson was created to make this text more understandable for all learners.

Originality/value
Like many NCSS Tradebooks that are beautiful in illustrations and lyrical prose, this book requires supports for young learners to decode and understand. This lesson plan scaffolds students’ understanding, especially ELLs’ understanding, of simile and metaphor as a tool to unlock a text’s meaning toward increased historical understanding of Sojourner’s life. Understanding the legacy of Sojourner Truth is evermore important to teach today – she was a woman empowered with knowledge of the law to recognize human rights violations and act on behalf of others.
Digitalization in practice: the fifth discipline advantage
Authors: Hoe Siu Loon 
Published: January 2020

Purpose
The purpose of this paper is to provide advice to organizations on how to become successful in the digital age. The paper revisits Peter Senge’s (1990) notion of the learning organization and discusses the relevance of systems thinking and the other four disciplines, namely, personal mastery, mental models, shared vision and team learning in the context of the current digitalization megatrend.

Design/methodology/approach
This paper is based on content analysis of essays from international organizations, strategy experts and management scholars, and insights gained from the author’s consulting experience. A comparative case study from the health and social sector is also included.

Findings
With the current digitalization megatrend sweeping across the globe, the practice of systems thinking would certainly become more crucial for organizations seeking to develop new digital ecosystems. In addition, the application of the other four disciplines of the learning organization would also help to nurture a digital culture for organizations to stay ahead of the competition.

Practical implications
Organizations and digitalization practitioners could benefit from applying systems thinking to develop digital ecosystems, and the other four disciples to nurture a digital culture.

Originality/value
This paper contributes to the existing literature by offering a relook and justifications on the relevance of the five disciplines, in particular systems thinking, in the present times. It offers advice to organizations on how to become successful as part of the digital transformation journey.
Facilitated personhood
Authors: Wolf‐Meyer Matthew 
Published: January 2020

AbstractAnthropological models of personhood suggest that the individual is produced through relational ties to others, including humans and nonhumans. American ideas about the individual are deeply ideological, obscuring the human relations that make ‘personhood’ a possible, desirable concept that motivates subjection. Attending to neurological disorders and the technologies that attempt to remedy communication impairments shows that not only is the labour of other humans obscured in producing the individual, but so are the facilitating capacities of technologies and institutions. This article focuses on memoirs of disability and ethnographic and historiographic research on neuroscience to show how personhood is facilitated and produced through engagements with people, technologies, and institutions that attempt to render particular forms of subjection through communicative practices.
Changes in emergency department dental visits after Medicaid expansion
Authors: Elani Hawazin W. , Kawachi Ichiro , Sommers Benjamin D. 
Published: January 2020

AbstractObjectivesTo estimate the effect of Medicaid expansion under the Affordable Care Act (ACA) on the frequency and payment source for Emergency Department (ED) visits for dental care.Study DesignRetrospective, quasi‐experimental study.Data Sources/Study SettingWe used the State Emergency Department Database to compare changes in ED visit rates and payment source for dental conditions among patients from 33 states. These states represent four distinct policy environments, based on whether they expanded Medicaid and whether their Medicaid programs provide dental benefits. We first assessed the number of ED dental visits before (2012) and after (2014) the ACA. Then, we used differences‐in‐differences regression to estimate changes in insurance for dental visits by nonelderly adults.Principal FindingsOur sample contained 375 944 dental ED visits. In states that expanded Medicaid and offered dental coverage, dental ED visits decreased by 14.1 percent (from 19 443 to 16 709, for a net difference of 2734). By contrast, in the remaining three state groups, dental ED visits rose. Meanwhile, the expansion significantly increased Medicaid coverage and decreased the rate of self‐pay for ED dental visits.ConclusionsMedicaid expansion, combined with adult dental coverage in Medicaid, was associated with a reduction in ED utilization for dental visits.
Estimation of the proportion of population cannabis consumption in Australia that is accounted for by daily users using Monte Carlo Simulation
Authors: Chan Gary C. K. , Hall Wayne 
Published: January 2020

AbstractAimTo estimate the proportion of cannabis consumed in Australia by daily cannabis users.DesignMonte Carlo simulation using parameters estimated from nationally representative and repeated cross‐sectional household surveys in 2007, 2010, 2013 and 2016.SettingAustraliaParticipantsAdult samples (mean age = 49.9; 55% females) from four National Drug Strategy Household Surveys (n = 92 243).MeasurementFrequency of cannabis use (daily/weekly/about once a month/every few months/once or twice a year). The weighted estimated prevalence of users in each of these frequency levels was multiplied by population size to estimate the total number of users. Quantity of cannabis use was measured as number of joints consumed. The consumption of those who reported using bongs was converted into joints based on the bong to joint ratio estimated from the survey data. We estimated the proportion of cannabis consumed by daily users by Monte Carlo simulation using parameters estimated from the household surveys. We conducted 10 000 simulation trials, and in each trial we [1] simulated the number of users at each consumption level (stratum) based on estimated prevalence and population size[2], for each simulated individual, we simulated the number of days of cannabis use in a year based on frequency data[3], for each consumption day, we simulated the quantity consumed [4] and lastly we calculated the total joints consumed at each consumption level and estimated the proportion of joints consumed by daily users out of the total consumption.FindingsThe prevalence of past‐year cannabis use increased from 8.9% [95% confidence interval (CI) = 8.5–9.4] in 2007 to 10.5% (95% CI = 10.0–11.1) in 2016, 16% of whom were daily users. Between 2007 and 2016, daily users accounted for between 81.6 and 85.7% of all cannabis consumed. Weekly users accounted for an additional 12.1–15.9%.ConclusionBetween 2007 and 2016, only one in six Australian cannabis users were daily users, but they accounted for more than 80% of the estimated cannabis consumed in Australia.
