Over the past decades, scholars advanced foundational insights about paradox in organization theory. In this double volume, we seek to expand upon these insights through interdisciplinary theorizing. We do so for two reasons. First, we think that now is a moment to build on those foundations toward richer, more complex insights by learning from disciplines outside of organization theory. Second, as our world increasingly faces grand challenges, scholars turn to paradox theory. Yet as the challenges become more complex, authors turn to other disciplines to ensure the requisite complexity of our own theories. To advance these goals, we invited scholars with knowledge in paradox theory to explore how these ideas could be expanded by outside disciplines. This provides a both/and opportunity for paradox theory: both learning from outside disciplines beyond existing boundaries and enriching our insights in organization scholarship. The result is an impressive collection of papers about paradox theory that draws from four outside realms – the realm of belief, the realm of physical systems, the realm of social structures, and the realm of expression. In this introduction, we expand on why paradox theory is ripe for interdisciplinary theorizing, explore the benefits of doing so, and introduce the papers in this double volume.

Interdisciplinary research allows us to broaden our sights and expand our theories. Yet, such research surfaces a number of challenges. We highlight three issues – superficiality, lack of focus, and consilience - and discuss how they can be addressed in interdisciplinary research. In particular, we focus on the implications for interdisciplinary work with paradox scholarship. We explore how these issues can be navigated as scholars bring together different epistemologies, ontologies and methodologies within interdisciplinary research, and illustrate our key points by drawing on extant work in paradox theory and on examples from this double volume. Our paper contributes to paradox scholarship, and to organizational theory more broadly, by offering practices about how to implement interdisciplinary research while also advancing our understanding about available research methods.

Inhibitory control (IC) is a central executive function that shows significant development throughout the preschool years. IC is known as a factor that underlies the ability to self-regulate in daily situations. This ability is challenged when a child faces negative emotions; a challenge that is seen in children’s IC performance and brain activity. This chapter elaborates on the effects that negative emotional experiences have on children’s IC functioning. Moreover, previous studies regarding the way emotional experiences are reflected in brain activity are included. Additionally, this chapter will offer a comprehensive review of the factors affecting individual differences in IC, including the role of children’s temperamental effortful control and negative affectivity. Further, the role of parenting behaviors will be discussed, focusing on the way in which maternal self-regulation influences child inhibitory control, including related educational implications.

This paper gives a review of the finite element techniques (FE) applied in the area of material processing. The latest trends in metal forming, non‐metal forming and powder metallurgy are briefly discussed. The range of applications of finite elements on the subjects is extremely wide and cannot be presented in a single paper; therefore the aim of the paper is to give FE users only an encyclopaedic view of the different possibilities that exist today in the various fields mentioned above. An appendix included at the end of the paper presents a bibliography on finite element applications in material processing for the last five years, and more than 1100 references are listed.

The purpose of this study is to investigate the interaction between magnetotactic bacteria and Fe₃O₄–water nanofluid (NF) in a wavy enclosure in the presence of 2D natural convection flow.

Uniform magnetic field (MF), Brownian and thermophoresis effects are also contemplated. The dimensionless, time-dependent equations are governed by stream function, vorticity, energy, nanoparticle concentration and number of bacteria. Radial basis function-based finite difference method for the space derivatives and the second-order backward differentiation formula for the time derivatives are performed. Numerical outputs in view of isolines as well as average Nusselt number, average Sherwood number and flux density of microorganisms are presented.

Convective mass transfer rises if any of Lewis number, Peclet number, Rayleigh number, bioconvection Rayleigh number and Brownian motion parameter increases, and the flux density of microorganisms is an increasing function of Rayleigh number, bioconvection Rayleigh number, Peclet number, Brownian and thermophoresis parameters. The rise in buoyancy ratio parameter between 0.1 and 1 and the rise in Hartmann number between 0 and 50 reduce all outputs average Nusselt, average Sherwood numbers and flux density of microorganisms.

This study implies the importance of the presence of magnetotactic bacteria and magnetite nanoparticles inside a host fluid in view of heat transfer and fluid flow. The limitation is to check the efficiency on numerical aspect. Experimental observations would be more effective.

In practical point of view, in a heat transfer and fluid flow system involving magnetite nanoparticles, the inclusion of magnetotactic bacteria and MF effect provide control over fluid flow and heat transfer.

This is a scientific study. However, this idea may be extended to sustainable energy or biofuel studies, too. This means that a better world may create better social environment between people.

The presence of magnetotactic bacteria inside a Fe₃O₄–water NF under the effect of a MF is a good controller on fluid flow and heat transfer. Since the magnetotactic bacteria is fed by nanoparticles Fe₃O₄ which has strong magnetic property, varying nanoparticle concentration and Brownian and thermophoresis effects are first considered.

Grounded in Critical Youth Studies and English education scholarship that examines the consequences of conceptions of adolescence on English teachers’ thinking about pedagogy, this chapter highlights two ways English teacher educators can facilitate pre-service English teachers’ interrogation of dominant discourses of adolescence/ts so they might be better positioned to create pedagogical practices aligned with more comprehensive understandings of secondary students. The first focuses on teaching a Youth Lens in the context of a Young Adult Literature course, an approach that helps future teachers learn about adolescence as a construct and the linkages between this idea and English pedagogy. The second focuses on integrating youth into English teacher education coursework as guest speakers on a range of English and schooling practices whereby they are “re-positioned” as experts and contributors to English teacher education. Together, these points of intervention provide ways to re-position youth systemically throughout English teacher education programs.

A small-scale study was conducted to qualitatively explore the “lived experiences” of persons who remarried between the ages of 55 and 75. Improved life expectancy, high divorce rates, increased odds of being widowed over time, and the need for intimate relationships across the lifespan are some of the factors associated with a recent increase in remarriage rates of older adults. While demographic trends indicate that repartnering in the later years will likely become more common, little is known about remarriage in the “young-old” years.

The study included in-depth, semistructured interviews with 11 newlyweds (seven females, four males) who had remarried between the ages of 55 and 75. Word-for-word transcripts were qualitatively analyzed through a process of open coding and constant comparison to identify salient themes related to the original research question “What is the transition to remarriage experience like for adults aged 55–75?”

Five themes emerged from the analysis of participant interviews: positive orientation toward remarriage, practical/pragmatic view of the union, desire for companionship, recognition of others’ feelings, and willingness to adapt.

The findings were salient to a small group of “young-old,” white, middle-class males and females from the Midwest and are not meant to be generalizable. The results can serve as a basis for further research and understanding of romantic relationships and repartnering across the life course.

This study helps to fill the gap that exists in the current literature related to romantic relationships and remarriage in the “young-old” years of life.

This research highlights the scenarios that might serve as a strategic vision to describe a future beyond the current library, one which both guides provosts and creates a map for the transformation of human resources and technology in the university research libraries. The scenarios offer managerial leaders an opportunity to envision new roles for librarians and staff which brings a much needed focus on the development of human resources as well as a thought-stream to understand decisions which effectively and systematically move the organization toward a strategic vision.

These scenarios also outline possible future directions research libraries could take by focusing on perspectives from library directors, provosts, and administrators for human resources. The four case study scenarios introduce potential future roles for librarians and highlight the unsustainability of the current scholarly communications model as well as uncertain factors related to the political, social, technical, and demographic issues facing campuses. Given the changes institutions face, scenarios allow directors to include more uncertainty when developing and articulating a vision. These scenarios may start a discussion, before a strategic planning process, to sharpen the evaluations and measures necessary to monitor achievements that define the value of the library.

The present numerical investigation examines the magnetohydrodynamic (MHD) double diffusion natural convection of power-law non-Newtonian nano-encapsulated phase change materials (NEPCMs) in a trapezoidal cavity.

The governing Navier-Stokes, energy and concentration equations based on the Cartesian curvilinear coordinates are solved using the collocated grid arrangement’s finite volume method. The in-house FORTRAN code is validated with the different benchmark problems. The NEPCM nanoparticles consist of a core-shell structure with Phase Change Material (PCM) at the core. The enclosure, shaped as a trapezoidal hollow, features a warmed (T_h) left wall and a cold (T_c) right wall. Various parameters are considered, including the power law index (0.6 ≤ n ≤ 1.4), Hartmann number (0 ≤ Ha ≤ 30), Rayleigh number (10⁴ ≤ Ra ≤ 10⁵) and fixed variables such as buoyancy ratio (Br = 0.8), Prandtl number (Pr = 6.2), Lewis number (Le = 5), fusion temperature (Θ_f = 0.5) and volume fraction (ϕ = 0.04).

The findings indicate a decrease in local Nusselt (Nu) and Sherwood (Sh) numbers with increasing Hartmann numbers (Ha). Additionally, for a shear-thinning fluid (n = 0.6) results in the maximum local Nu and Sh values. As the Rayleigh number (Ra) increases from 10⁴ to 10⁵, the structured vortex in the streamline pattern is disturbed. Furthermore, for different Ra values, an increase in n from 0.6 to 1.4 leads to a 67.43% to 76.88% decrease in average Nu and a 70% to 77% decrease in average Sh.

This research is for two-dimensioal laminar flow only.

PCMs represent a class of practical substances that behave as a function of temperature and have the innate ability to absorb, release and store heated energy in the form of hidden fusion enthalpy, or heat. They are valuable in these systems as they can store significant energy at a relatively constant temperature through their latent heat phase change.

As per the literature review and the authors’ understanding, an examination has never been conducted on MHD double diffusion natural convection of power-law non-Newtonian NEPCMs within a trapezoidal enclosure. The current work is innovative since it combines NEPCMs with the effect of magnetic field Double diffusion Natural Convection of power-law non-Newtonian NEPCMs in a Trapezoidal enclosure. This outcome can be used to improve thermal management in energy storage systems, increasing safety and effectiveness.

With the help of multi-body dynamics software UM, the paper uses Kik–Piotrowski model to simulate wheel-rail contact and Archard wear model for rail wear.

The CRH5 vehicle-track coupling dynamics model is constructed for the wear study of rails of small radius curves, namely 200 and 350 m in Guangzhou East EMU Depot and those 250 and 300 m radius in Taiyuan South EMU Depot.

Results show that the rail wear at the straight-circle point, the curve center point and the circle-straight point follows the order of center point > the circle-straight point > the straight-circle point. The wear on rail of small radius curves intensifies with the rise of running speed, and the wearing trend tends to fasten as the curve radius declines. The maximum rail wear of the inner rail can reach 2.29 mm, while that of the outer rail, 10.11 mm.

With the increase of the train passing number, the wear range tends to expand. The rail wear decreases with the increase of the curve radius. The dynamic response of vehicle increases with the increase of rail wear, among which the derailment coefficient is affected the most. When the number of passing vehicles reaches 1 million, the derailment coefficient exceeds the limit value, which poses a risk of derailment.
