(Un)Sanctioned: young adult literature as meaningful sponsor for writing teacher education
Authors: Sams Brandon L. , Cook Mike P. 
Published: April 2019

PurposeThe purpose of this paper is to examine youth literacy and writing practices in select, contemporary young adult literature (YAL), especially how and why literate activity is sponsored, negotiated or occluded by teachers and schools.Design/methodology/approachThe authors position young adult fiction as case studies of youth composing in and out of school. Drawing on Stake's (1995) features of case study research in education, the authors present readings ofGabi, a Girl in Piecesby Isabel Quintero andThe Vigilante Poets of Selwyn Academyby Kate Hattemer that highlight particular problems and insights about youth literacy practices that are worth extended examination and reflection.FindingsBoth novels feature youth engaging in powerful literacy and writing practices across a range of modes to critically read and write their worlds. These particular texts – and other YAL featuring youth composing – offer teacher educators and pre-service teachers opportunities for critical reflection on their evolving stances on literacy instruction; identities as writing and literacy educators; and pedagogies that enable robust literate activity.Originality/valueIn the US educational context, teacher education programs are required to provide pre-service teachers numerous opportunities to observe and participate as teachers in public school classrooms. YAL offers a unique setting of experience that can be productively paired with more traditional field placements to complement pre-service writing teacher education. Reading YAL featuring youth composing can serve as a useful occasion of reflection on pedagogies that limit and/or make possible students’ meaningful engagement with words and the world.

Authors: Rathi Neha , Riddell Lynn , Worsley Anthony 
Published: April 2019

PurposeNutrition education plays a significant role in inculcating lifelong healthy dietary behaviours among adolescents. The purpose of this paper is to understand the opinions of parents and teachers regarding nutrition education in private Indian secondary schools.Design/methodology/approachA cross-sectional, self-administered, paper-based survey comprising both closed- and open-ended questions was completed by 32 teachers and 280 parents who were recruited from five private English-speaking secondary schools in Kolkata, India. Descriptive and cross-tabulation analyses were conducted to compare the responses of teachers and parents. Thematic data analysis informed by template analysis technique was performed to evaluate the qualitative data.FindingsWhile the curriculum was considered interesting and easy to understand, the gendered nature of the curriculum, excessive rote learning and lack of synchrony between the curriculum and school food services were highlighted as shortcomings of the existing curriculum. The need for the dissemination of food skills either through a compulsory food and nutrition curriculum or through extra-mural activities was expressed by most respondents. Both these ideas were indicative of strong support and motivation for modification in the current curriculum.Practical implicationsThese findings emphasise the support for a skills-focussed food and nutrition curriculum to inculcate experiential culinary skills and comprehensive nutrition knowledge in Indian adolescents, thus improving their nutritional and health profiles.Originality/valueThis is the first cross-sectional survey to investigate the views of parents and teachers about the status of food and nutrition education in private Indian secondary schools.

Authors: Biswal Uddhaba , Chakraverty Snehashish , Ojha Bata Krushna 
Published: April 2019

Purpose
The purpose of this paper is to carry out a detailed investigation to study the natural convection of a non-Newtonian nanofluid flow between two vertical parallel plates. In this study, sodium alginate has been taken as a base fluid and nanoparticles that added to it are copper and silver. Maxwell–Garnetts and Brinkman models are used to calculate the effective thermal conductivity and viscosity of nanofluid, respectively.

Design/methodology/approach
The authors used two methods in this study, namely, Galerkin’s method and homotopy perturbation method.

Findings
This paper investigates the velocity and temperature profile of nanofluid and the real fluid flow between two vertical parallel plates. The impacts of physical parameters such as nanofluid volume fraction and dimensionless non-Newtonian viscosity are discussed.

Originality/value
Coupled non-linear differential equations are solved for velocity and temperature. A model is proposed in such a way that the authors may get the solution of real fluid from the nanofluid by neglecting the nano term. The authors do not require a further calculation for real fluid problem.
Natural convection of a hybrid nanofluid subjected to non-uniform magnetic field within porous medium including circular heater
Authors: Izadi Mohsen , Maleki Nemat M. , Pop Ioan , Mehryan S.A.M. 
Published: April 2019

Purpose
This paper aims to numerically investigate the natural convection heat transfer of a hybrid nanofluid into a porous cavity exposed to a variable magnetic field.

Design/methodology/approach
The non-linear elliptical governing equations have been solved numerically using control volume based finite element method. The effects of different governing parameters including Rayleigh number (Ra = 103 − 106), Hartman number (Ha = 0 − 50), volume fraction of nanoparticles (φ = 0 − 0.02), curvature of horizontal isolated wall (a = 0.85 − 1.15), porosity coefficient (ε = 0.1 − 0.9) and Darcy number (Da = 10−5 − 10−1) have been studied.

Findings
The results indicate that at low Darcy numbers close to 0, the average Nusselt number Nua enhances as porosity coefficient increases. For a = 1 and a = 1.15 in comparison with a = 0.85, the stretching of the isothermal lines is maintained from the left side to the right side and vice versa, which indicates increased natural convection heat transfer for this configuration of the top and bottom walls. In addition, at higher Rayleigh numbers, by increasing the Hartmann number, a significant decrease is observed in the Nusselt number, which can be attributed to the decreased power of the flow.

Originality/value
The authors believe that all the results, both numerical and asymptotic, are original and have not been published elsewhere.
Simulations of flame propagation during the ignition process in an annular multiple-injector combustor
Authors: Zhao Dongmei , Xia Yifan , Ge Haiwen , Lin Qizhao , Zou Jianfeng , Wang Gaofeng 
Published: April 2019

Purpose
Ignition process is a critical issue in combustion systems. It is particularly important for reliability and safety prospects of aero-engine. This paper aims to numerically investigate the burner-to-burner propagation during ignition process in a full annular multiple-injector combustor and then validate it by comparing with experimental results.

Design/methodology/approach
The annular multiple-injector experimental setup features 16 swirling injectors and two quartz tubes providing optical accesses to high-speed imaging of flames. A Reynolds averaged Navier–Stokes model, adaptive mesh refinement (AMR) and complete San Diego chemistry are used to predict the ignition process.

Findings
The ignition process shows an overall agreement with experiment. The integrated heat release rate of simulation and the integrated light intensity of experiment is also within reasonable agreement. The flow structure and flame propagation dynamics are carefully analyzed. It is found that the flame fronts propagate symmetrically at an early stage and asymmetrically near merging stage. The flame speed slows down before flame merging. Overall, the numerical results show that the present numerical model can reliably predict the flame propagation during the ignition process.

Originality/value
The dedicated AMR method together with detailed chemistry is used for predicting the unsteady ignition procedure in a laboratory-scale annular combustor for the first time. The validation shows satisfying agreements with the experimental investigations. Some details of flow structures are revealed to explain the characteristics of unsteady flame propagations.
Effects of internal marketing on job satisfaction in the banking sector
Authors: Mainardes Emerson Wagner , Rodrigues Lázaro Silva , Teixeira Aridelmo 
Published: April 2019

PurposeThe purpose of this paper is to verify the relationship of job satisfaction in the banking sector with its antecedent constructs (financial rewards and psychological rewards) and the mediating role of internal marketing in this relationship and to verify the relationship between job satisfaction in the banking sector and its consequent constructs (work engagement and the intention to leave) and the moderating effect of internal marketing on this relationship.Design/methodology/approachThe paper adopts a quantitative, descriptive, cross-sectional research methodology. Data are collected through an online questionnaire, which involves 355 bank employees. Partial least squares–structural equation modeling is used to verify the predicted relationships.FindingsThe results show that internal marketing tends to mediate the relationship between financial rewards and job satisfaction and the relationship between psychological rewards and job satisfaction. Internal marketing presents a moderating effect on the relationship between job satisfaction and work engagement, but internal marketing does not moderate the relationship between job satisfaction and the intention to leave the bank.Originality/valueThis study expands the understanding of the scope of internal marketing by exploring its mediating and moderating effects on the interactions among the behaviors of banking sector employees.
Gender gap in entrepreneurial growth ambition
Authors: Wang Jing , Li Yaokuang , Long Dan 
Published: April 2019

PurposeSince the limited growth of enterprises has been identified as a deliberate choice of women entrepreneurs, the purpose of this paper is to illustrate how the institutional environment of an entrepreneurial ecosystem (EE) fosters the gender gap in entrepreneurial growth intention. The mediating role of the perceived institutional environment in the gender effect on entrepreneurial growth intention is tested in the Chinese context. As individuals’ cognitions are usually influenced by their cultural orientations, the gender difference in perceptions of the institutional environment is considered to be contingent on entrepreneurs’ self-construal.Design/methodology/approachUsing a multiregional sample of 206 Chinese entrepreneurs who completed the questionnaire, the study obtained results by adopting a structural equation modelling analysis with a partial least squares approach.FindingsThere are significant gender gaps in perceptions of the institutional environment and growth intention among Chinese entrepreneurs. Due to their limited political ties and lower legitimacy in economic activities in the country, Chinese women entrepreneurs have more negative perceptions of the regulative and cognitive institutional environment than their male counterparts, which accounts for the lack of growth ambition among Chinese women entrepreneurs. Independent self-construal enlarges the difference in environmental perceptions between male and female entrepreneurs.Originality/valueThis research enriches the discussion in the emerging area of EEs by adequately responding to the highlighted target to advance ambitious entrepreneurship and offering an interpretation of its evolutionary thinking. Given the increasing calls for a focus on high-growth women’s entrepreneurship, this study provides an explanation for how the institutional environment engenders the absence of women in growth-oriented entrepreneurial activities. It also uncovers the overlooked deficiency in institutional practice by highlighting the gender inequality in the implementation process of entrepreneurial support policies and the distribution of entrepreneurial capabilities in society.
Senior public leaders’ perceptions of business intelligence
Authors: Hellström Mikael , Ramberg Ulf 
Published: April 2019

Purpose
The purpose of this paper is to address the perceptions senior public leaders in local government have regarding the need for business intelligence and their perceptions of the extent to which their organizations are capable of effectively assimilating business intelligence.

Design/methodology/approach
The data are from a survey on local governments’ need for and capability to use business intelligence, with a response rate of 50.5 percent, and semi-structured interviews. The survey method originates from private sector research but is adapted to local government conditions in Sweden.

Findings
The leaders’ perceptions about the need for business intelligence were fragmented. Their perceptions regarding its use were even more fragmented, both between different municipalities and within municipalities.

Research limitations/implications
The survey is adapted to local government conditions in Sweden and may need further changes to fit other settings. The adaptation and renewal of questions can lead to summation errors in relation to the original survey.

Practical implications
The paper highlights some of the strategic areas where senior public leaders need to advance their business intelligence and prioritize specific organizational capabilities. The dominant logic, enhancing an inward-looking approach, seems to prevent a more thoroughgoing business analysis.

Originality/value
The adaptation of a method that is mainly used in the private sector can give new perspectives to senior public leaders regarding the need for and use of business intelligence and can help them identify the factors that can affect the complexity and volatility in local government settings.
Influence of positive texturing on friction and wear properties of piston ring-cylinder liner tribo pair under lubricated conditions
Authors: P. Venkateswara Babu , Syed Ismail , Beera Satish Ben 
Published: April 2019

Purpose
In an internal combustion engine, piston ring-cylinder liner tribo pair is one among the most critical rubbing pairs. Most of the energy produced by an internal combustion engine is dissipated as frictional losses of which major portion is contributed by the piston ring-cylinder liner tribo pair. Hence, proper design of tribological parameters of piston ring-cylinder liner pair is essential and can effectively reduce the friction and wear, thereby improving the tribological performance of the engine. This paper aims to use surface texturing, an effective and feasible method, to improve the tribological performance of piston ring-cylinder liner tribo pair.

Design/methodology/approach
In this paper, influence of positive texturing (protruding) on friction reduction and wear resistance of piston ring surfaces was studied. The square-shaped positive textures were fabricated on piston ring surface by chemical etching method, and the experiments were conducted with textured piston ring surfaces against un-textured cylinder liner surface on pin-on-disc apparatus by continuous supply of lubricant at the inlet of contact zone. The parameters varied in this study are area density and normal load at a constant sliding speed. A comparison was made between the tribological properties of textured and un-textured piston ring surfaces.

Findings
From the experimental results, the tribological performance of the textured piston ring-cylinder liner tribo pair was significantly improved over a un-textured tribo pair. A maximum friction reduction of 67.6 per cent and wear resistance of 81.6 per cent were observed with textured ring surfaces as compared to un-textured ring surfaces.

Originality/value
This experimental study is helpful for better understanding of the potency of positive texturing on friction reduction and wear resistance of piston ring-cylinder liner tribo pair under lubricated sliding conditions.
The trials and tribulations of JTH Inc.
Authors: Jaiswal Mayank , Maxwell Robert 
Published: April 2019

Theoretical basis
The theoretical linkages are with dynamic nature of PESTEL analysis, Porter’s five forces, resource-based view of the firm and characteristics of an entrepreneur.

Research methodology
The names of the institutions and individuals involved have been disguised. However, the material facts of the case are authentic.

Case overview/synopsis
This case discusses strategy in the context of a crisis situation in a small business. JTH Inc. was a computer subcontract manufacturing (SCM) firm serving the New England region of the USA. The influx of international competition (mainly from China) due to recession led to significant challenges for JTH and the SCM industry. JTH was struggling and the situation was further complicated by the founder’s (Robert Maxwell) personal and emotional situation. Robert had to decide whether to keep the business running, close it down, merge with/be acquired by a competitor, innovate the business model or do something else.

Complexity academic level
This case is designed to target undergraduate students of Strategic Management; it may also include Entrepreneurship students. It should most probably be taught in the first half of the course after concepts such as PESTEL, Porter and resource-based view of the firm have been taught.
Plant species richness elicits changes in the metabolome of grassland species via soil biotic legacy

Abstract

Species‐rich plant communities can induce unique soil biotic legacy effects through changing the abundance and composition of soil biota. These soil legacy effects can cause feedbacks to influence plant performance. In addition, soil biota can induce (defensive) secondary metabolites in shoots and roots and thus affect plant–herbivore interactions. We hypothesize that plant diversity‐driven soil biotic legacy effects elicit changes in the shoot and root metabolome.

We tested this hypothesis by establishing an experiment with four plant species. We grew plants in a sterile substrate inoculated with soil conditioned by different plant species communities: (a) monocultures of either of the four species, (b) the four species in a mixture, (c) an eight species mixture including all four species or (d) a sterile inoculum. After at least 8 weeks in the field, we estimated shoot herbivory. At the same time, we took root and shoot samples for metabolomics analyses by liquid chromatography quadrupole time‐of‐flight mass spectrometry.

We found that shoot and root metabolomes of all plants grown in sterile soil differed significantly from those grown in living soil. The plant metabolomes in living soils differed by species and tissue. Across all species, shoots displayed a greater richness of secondary metabolites than roots. The richness of secondary metabolites differed by species and among living soils. The conditioning species richness significantly affected the Shannon diversity of secondary metabolites in Centaurea jacea. Shoot herbivory positively correlated with the richness and Shannon diversity of secondary metabolites in Leucanthemum vulgare. We detected multiple metabolites that together explained up to 88% of the variation in herbivory in the shoots of C. jacea and Plantago lanceolata.

Synthesis. Our findings suggest that plant diversity‐driven shifts in soil biota elicit changes in the composition and diversity of shoot and root secondary metabolites. However, these plant responses and their effect on shoot herbivores are species‐specific. Tracking changes in plant secondary chemistry in response to soil biotic legacy effects will help to understand the mechanisms that govern species‐specific plant–plant and plant–herbivore interactions.

Published: April 2019

BackgroundThe lung is one of the most common target organs for malignant tumor metastasis. The existence of lung metastasis may have a decisive effect on the choice of treatment regimen. Minute pulmonary meningothelial‐like nodules (MPMNs) usually present as ground‐glass opacity or solid nodules, mimicking the imaging findings of malignant pulmonary nodules. This study summarizes the clinical, radiological, and pathological features of MPMNs to distinguish them from malignant pulmonary nodules.MethodsThe Guangdong Lung Cancer Institute Pathology Information System was searched using the key words “minute meningothelioid nodules” and “lung.” Patients who underwent pulmonary resection from 23 February 2009 to 31 May 2017 were included in the study. The 11th edition of Rosai and Ackerman's Surgical Pathology was used to confirm the diagnosis. The clinical, imaging, and pathological characteristics of MPMNs were recorded.ResultsTwelve patients had MPMNs. MPMNs were associated with cancerous or precancerous lesions (10/12), female gender (11/12), and non‐smokers (11/12). Four patients were misdiagnosed with malignant pulmonary nodules before surgery. Positron emission tomography‐computed tomography revealed an increased maximum standardized uptake value in one patient. Immunohistochemistry identified eight specimens positive for vimentin, EMA, and PR and negative for TTF‐1 and CK.ConclusionsMPMNs tend to coexist with malignant tumors, mimicking the imaging findings of malignant pulmonary nodules, thus resulting in misdiagnosis. Dynamic monitoring or an invasive examination may help to distinguish MPMNs from malignant lesions.
