Abstract

Purpose

The purpose of this paper is to examine the career shocks of Red Cross (RC) of Serbia staff and volunteers providing aid during the 2016 migrants’ influx. Specifically, the authors explore what the volatile environment in which RC staff and volunteers work can teach us about career shocks, and what makes a career shock for people whose everyday work entails stressful events.

Design/methodology/approach

This study examined a number of anecdotes that reflect the career shock construct to a greater or lesser extent. These anecdotes were developed by RC staff and volunteers as part of a communications training storytelling exercise.

Findings

The authors analyzed these events from the perspective of recent developments in career shocks research and examined whether the anecdotes contained elements that would enable us to differentiate between career shocks and stressors. Those anecdotes found to be the most prototypical of career shocks, as opposed to stressors, were found to instigate in-depth reflection about the career, were identity related, and had a tangible career impact. Shocking events in the eyes of RC people entailed work demands that go beyond expectations, excessive media scrutiny, and conflicting values. The authors discuss how organizational values, fostering person–organization fit, providing organizational and collegial support, and deploying “weathered” staff, could comprise the “vaccine” that makes the organization immune to career shocks.

Originality/value

By taking a data before theory approach to the study of career shocks, this paper provides a novel perspective on the lived experiences of RC people, and how such experiences may be classified into career shocks or stressors.

Abstract

Purpose

With the ageing global population the demand for nursing jobs and the requirements for complex care provision are increasing. In consequence, nursing professionals need to be ready to adapt, obtain variety of skills and engage in career self-management. The purpose of this paper is to investigate individual, micro-level, resources and behaviors that can facilitate matching processes between nursing professionals and their jobs.

Design/methodology/approach

A survey-based study was conducted among 314 part-time and full-time nursing professionals in Hungary.

Findings

Consistent with the career construction theory, this study offers evidence on career adaptability as a self-regulatory resource that might stimulate nurses’ adaptation outcomes. Specifically, it demonstrates positive relationships between adaptive readiness (proactive personality and conscientiousness), career adaptability, adapting behaviors (career planning and proactive skill development) and adaptation outcomes (employability and in-role performance).

Research limitations/implications

The cross-sectional design limits causal inference. Relatively small sample of full-time professionals for whom supervisory-ratings were obtained yields the need of further replication.

Practical implications

Stimulating development of nurses’ career adaptability, career planning, and proactive skill development can contribute to sustainable career management. It can facilitate the alignment of nurses to performance requirements of their current jobs, preventing individual person-job mismatch.

Originality/value

Zooming into the context of nursing professionals in Hungary, the study elucidates the understudied link between adaptivity and adapting responses and answers the call for more research that employs other-ratings of adaptation outcomes. It demonstrates the value of career adaptability resources for nurses’ employability and in-role performance.

Abstract

Purpose

Natural gas leak from underground pipelines could lead to serious damage and global warming, whose spreading in soil should be systematically investigated. This paper aims to propose a three-dimensional numerical model to analyze the methane–air transportation in soil. The results could help understand the diffusion process of natural gas in soil, which is essential for locating leak source and reducing damage after leak accident.

Design/methodology/approach

A numerical model using finite element method is proposed to simulate the methane spreading process in porous media after leaking from an underground pipe. Physical models, including fluids transportation in porous media, water evaporation and heat transfer, are taken into account. The numerical results are compared with experimental data to validate the reliability of the simulation model. The effects of methane leaking direction, non-uniform soil porosity, leaking pressure and convective mass transfer coefficient on ground surface are analyzed.

Findings

The methane mole fraction distribution in soil is significantly affected by the leaking direction. Horizontally and vertically non-uniform soil porosity has a stronger effect. Increasing leaking pressure causes increasing methane mole flux and flow rate on the ground surface.

Originality/value

Most existing gas diffusion models in porous media are for one- or two-dimensional simulation, which is not enough for predicting three-dimensional diffusion process after natural gas leak in soil. The heat transfer between gas and soil was also neglected by most researchers, which is very important for predicting the gas-spreading process affected by the soil moisture variation because of water evaporation. In this paper, a three-dimensional numerical model is proposed to further analyze the methane–air transportation in soil using finite element method, with the presence of water evaporation and heat transfer in soil.

Abstract

Purpose

This paper aims to describe and investigate the mathematical models and numerical modeling of how a cell membrane is affected by a transient ice freezing front combined with the influence of thermal fluctuations and anisotropy.

Design/methodology/approach

The study consists of mathematical modeling, validation with an analytical solution, and shows the influence of thermal noises on phase front dynamics and how it influences the freezing process of a single red blood cell. The numerical calculation has been modeled in the framework of the phase field method with a Cahn–Hilliard formulation of a free energy functional.

Findings

The results show an influence scale on directional phase front propagation dynamics and how significant are stochastic thermal noises in micro-scale freezing.

Originality/value

The numerical calculation has modeled in the framework of the phase field method with a Cahn–Hilliard formulation of a free energy functional.

Abstract

Purpose

The purpose of this paper is to consider heat and mass transfer on magnetohydrodynamics (MHD) Williamson fluid flow over a slendering stretching sheet with variable thickness in the presence of radiation and chemical reaction. All pertinent flow parameters are discussed and their influence on the hydrodynamics, thermal and concentration boundary layer are presented with the aid of the diagram.

Design/methodology/approach

The governing partial differential equations are reduced into a system of ordinary differential equations with the help of suitable similarity variables. A discrete version of the homotopy analysis method (HAM) called the spectral homotopy analysis method (SHAM) was used to solve the transformed equations. SHAM is efficient, and it converges faster than the HAM. The SHAM provides flexibility when solving linear ordinary differential equations with the use of the Chebyshev spectral collocation method.

Findings

The findings revealed that an increase in the variable thermal conductivity hike the temperature and the thermal boundary layer thickness, whereas the reverse is the case for velocity close to the wall.

Originality/value

The uniqueness of this paper is the exploration of combined effects of heat and mass transfer on MHD Williamson fluid flow over a slendering stretching sheet. The Williamson fluid term in the momentum equation is expressed as a linear function and the viscosity and thermal conductivity are considered to vary in the boundary layer.

Abstract

Purpose

There are a number of different approaches for calculating creep-fatigue (CF) damage for design, such as the French nuclear code RCC-MRx, the American ASME III NH and the British R5 assessment code. To acquire estimates for the CF damage, that are not overly conservative, both the cyclic material softening/hardening and the potential changes in relaxation behavior have to be considered. The data presented here and models are an initial glimpse of the ongoing European FP7 project MATISSE effort to model the softening and relaxation behavior of Grade 91 steel under CF loading. The resulting models are used for calculating the relaxed stress at arbitrary location in the material cyclic softening curve. The initial test results show that softening of the material is not always detrimental. The initial model development and the pre-assessment of the MATISSE data show that the relaxed stress can be robustly predicted with hold time, strain range and the cyclic life fraction as the main input parameters. The paper aims to discuss these issues.

Design/methodology/approach

Engineering models have been developed for predicting cyclic softening and relaxation for Gr. 91 steel at 550 and 600°C.

Findings

A simple engineering model can adequately predict the low cycle fatigue (LCF) and CF softening rates of Gr. 91 steel. Also a simple relaxation model was successfully defined for predicting relaxed stress of both virgin and cyclically softened material.

Research limitations/implications

The data are not yet complete and the models will be updated when the complete set of data in the MATISSE project is available.

Practical implications

The models described can be used for predicting P91 material softening in an arbitrary location (n/Nf0) of the LCF and CF cyclic life. Also the relaxed stress in the softened material can be estimated.

Originality/value

The models are simple in nature but are able to estimate both material softening and relaxation in arbitrary location of the softening curve. This is the first time the Wilshire methodology has been applied on cyclic relaxation data.

Abstract

Purpose

To introduce the presumed cultural similarity paradox as a possible explanation for the findings that adjusting to a culturally similar country is just as difficult as adjusting to a culturally dissimilar country. We provide a conceptual framework, enabling further understanding and research into this phenomenon.

Design/methodology/approach

Expatriates moving to a country that shares common characteristics may presume more cultural similarity and easier adjustment than is actually the case. During their stay abroad, expatriates may find that these expectations are not met. While the smaller cultural distance may facilitate adjustment, the undermet expectations inhibit adjustment and performance.

Findings

A first preliminary test compared Dutch expatriates in Belgium (culturally similar) and in China (culturally dissimilar). The expectations of cultural similarity and adjustment difficulty of the expatriates in Belgium were significantly more undermet than those of the expatriates in China and this had a negative influence on affective adjustment. The larger cultural distance of China was negatively related to intercultural adjustment. Better adjustment, both affective and intercultural, led to better job performance.

Research limitations/implications

Future research should try to replicate and extend our findings to other cultural contexts.

Practical implications

Expatriates and their employers must consider and prepare for the increased chance of undermet expectations and the negative consequences this can have on adjustment and job performance, when moving to a culturally similar country.

Social implications

Expatriates and their employers must consider and prepare for the increased chance of undermet expectations and the negative consequences this can have on adjustment and job performance, when moving to a culturally similar country.

Originality/value

This paper conceptualizes and provide a theoretical framework that should allow future research to empirically test the psychological process that occurs in this paradox, accommodate the contrasting effects of cultural distance and met expectations of cultural similarity and investigate which characteristics of countries lead expatriates to presume more cultural similarity than is the case.

Abstract

Presents a new method for the numerical simulation of diffusion with phase‐change. The method is able to handle hysteresis and finite‐rate kinetics in the phase‐change reaction. Such phenomena are frequent in solid‐solid phase transitions. The model problem discussed concerns hydrogen migration and hydride precipitation in zirconium and its alloys, a problem of interest to the nuclear industry. With respect to previous ones, our method is the first to incorporate an implicit treatment of diffusion, thus avoiding mesh‐dependent stability limits in the time step. The CPU time can in this way be reduced by a factor of 10–20 in applications. Addresses, through numerical studies, convergence with respect to mesh refinement and reduction of the time step. Also reports on an application of the method to the simulation of laboratory experiments. Shows that the method is a powerful tool to deal with general phase‐change problems, extendable to other physical systems.
