Abstract

Purpose

The purpose of this paper is to identify the relationships between structural empowerment and patient identification behaviors of nurses.

Design/methodology/approach

The present study was a descriptive survey using a self-reported questionnaire, following a quality improvement project at a hospital in South Korea. The participants included 984 registered nurses, who administer medication and transfusions to patients in the hospital. Data were analyzed using the t-test, ANOVA, Scheffé’s test, Pearson correlation coefficients and multiple regression analysis.

Findings

The patient identification behaviors of nurses were significantly correlated with opportunity, support, information, resources, formal power and informal power of structural empowerment. The support, information and informal power of structural empowerment, as well as the age and gender of the participants explained 10.7 percent of the variance in the patient identification behaviors of nurses.

Research limitations/implications

The present study has some limitations. Although the data collected by the cross-sectional survey were analyzed, causal analysis could not have been conducted. Nursing managers can promote safety by creating a work environment that facilitates access to the support, information and resources needed for nurses to perform their duties effectively; providing opportunities for nurses to learn and develop professionally; acknowledging the achievements of nurses; and expanding their duties, so that nurses can demonstrate greater work flexibility. Future studies should investigate structural empowerment in multiple nursing organizations, and particularly the organizational characteristics that affect structural empowerment.

Originality/value

The present study confirms that structural empowerment influences the patient identification behaviors of nurses.

Abstract

Purpose

The purpose of this paper is to empirically test the relationship between the empowering structure and the employees’ innovative behavior and the role of psychological empowerment in mediating this link.

Design/methodology/approach

Structural equation modeling was used to analyze data from 401 female primary school teachers in India. Prior to the main study, the scales were tested on a sample of 288 teachers. While psychological empowerment and structural empowerment were based on the self-reporting by the teachers, the innovative behavior of the teacher was assessed by two to three colleagues for each teacher.

Findings

The results confirmed that structural empowerment leads to innovative behavior and psychological empowerment and partially mediates the relationship between structural empowerment and innovative behavior.

Practical implications

Promising ideas die down because of lack of proper resource support and a free flow of information exchange despite employees’ willingness to carry out innovative tasks. Psychological empowerment affects creative intention in the workplace and can play a critical role for employees at their workplace.

Social implications

In the context of development at the teacher and school levels, it is imperative to address both the psyche of the individual and the existing structure in schools.

Originality/value

This study makes two critical contributions. One, it emphasizes the importance of structural empowerment in ensuring innovative behavior of employees. Two, it also brings forward the importance of psychological empowerment in the relationship between structural empowerment and innovative behavior.

Abstract

In this chapter, we draw on social capital and role theories to develop a theoretical model of global leader initiative and reputational effectiveness in spanning structural holes. We define global leaders as those assigned to work locations outside the borders of their home country. Global leaders (by virtue of their global work assignments) occupy structural holes that span geographical boundaries. By definition, this position provides them with special opportunities to use their social capital to span these structural holes. Our model aims to make two key contributions. First, we focus on firm and individual factors that influence the extent to which global leaders proactively use their social capital. Second, we address local, corporate, and personal factors that influence the relationship between spanning behavior and reputational effectiveness. We discuss research implications for testing our propositions and practical implications for applying the model to work organizations, with an emphasis on the benefits of more effectively leveraging the social capital of global leaders.

Abstract

Purpose

Reinforced concrete structural frames with masonry infills (infill-frames) are commonly used for construction worldwide. While the behavior of such frames has been studied extensively in the context of earthquake loading, studies related to their fire performance are limited. Therefore, this study aims to characterize the behavior of infill-frames under fire exposure by presenting a state-of-the-art literature review of the same.

Design/methodology/approach

Both experimental and computational studies have been included with a special emphasis on numerical modeling (simplified as well as advanced). The cold behavior of the infill-frame and its design requirements in case of fire exposure are first reviewed to set the context. Subsequently, the applicability of numerical modeling strategies developed for modeling cold infill-frames to simulate their behavior under fire is critically examined.

Findings

The major hurdles in developing generic numerical models for analyzing thermo-mechanical behavior of infill-frames are identified as: lack of temperature-dependent material properties, scarcity of experimental studies for validation and idealizations in coupling between thermal and structural analysis.

Originality value

This study presents one of the most popular research problems connected with practical and reliable utilization of numerical models, as a good alternative to expensive traditional furnace testing, in assessing fire resistance of infill-frames. It highlights major challenges in thermo-mechanical modeling of infill-frames and critically reviews the available approaches for modeling infill-frames subjected to fire.

Abstract

Purpose

Despite recognizing the significance of risk-based frameworks in fire safety engineering, the usual approach in structural fire design is largely member/component level, wherein effect of uncertainties influencing the fire resistance of structures are not explicitly considered. In this context, a probabilistic framework is presented to investigate the vulnerability of a reinforced concrete (RC) members and structure under fire loading scenario.

Design/methodology/approach

The RC structures exposed to fire are modeled in a finite element (FE) platform incorporating material and geometric nonlinearity, in which the transient thermo-mechanical analysis is carried out by suitably incorporating the temperature variation of thermal and mechanical properties of both concrete and steel rebar. The stochasticity in the system is considered in structural resistance, thermal and fire model parameters, and the subsequent fragility curves are developed considering threshold limit state of deflection.

Findings

The fire resistance of RC structure is reported to be significantly lower in comparison to the RC members, thereby illustrating the current prescriptive design approaches based on studies of structural member behavior to be crucial from a safety and reliability point of view.

Practical implications

The framework developed for the vulnerability assessment of RC structures under fire hazard through FE analysis can be effectively used to estimate the structural fire resistance for other similar structure to enhance safety and reliability of structures under such extreme threats.

Originality/value

The paper proposes a novel methodology for vulnerability assessment of three-dimensional RC structures under fire hazard through FE analysis and provides comparison of the structural fragility with fragility developed for structural members. Moreover, the research emphasizes to assume 3D behavior of the structure rather than the approximate 2D behavior.

Abstract

Purpose

This paper aims to provide a parametric investigation into the behaviour of steel, concrete and composite beams exposed to fire. This investigation gives insight into the structural behaviour of elements experiencing thermal and mechanical loading illustrating reasons for observed global structural behaviour, and identifying how selected design parameters influence results obtained. Non-linear heating/thermal bowing behaviour is specifically considered.

Design/methodology/approach

Cross-sectional stresses and strains, resultant thermal forces, bending stiffness, axial stiffness and deflections are plotted for beams subjected to different fire regimes or input values. The impact of changes in input parameters on beam section properties is illustrated. Unusual structural responses, localised effects and general trends are identified in relation to variations in thermal gradients, concrete tensile capacity, standard fire exposure time and the assumed concrete flange widths of composite beams.

Findings

Stress-strain plots highlighting cross-sectional structural behaviour, trends in beam properties and the influence of design parameters are provided. Some counter-intuitive behaviour is explained, such as increased member stiffness being offset by increased thermal effects, leading to this parameter having negligible impact on global behaviour but a significant effect on local stresses and strains. Increased concrete strengths may lead to increased thermal deformations, whilst the inclusion of concrete tensile capacity typically has a minimal influence.

Research limitations/implications

The research focusses on cross-sectional properties, although results generated illustrate how global behaviour is affected.

Practical implications

Design engineers are made aware of how selected input values influence predicted structural response. Also, localised stress and strain behaviour relative to imposed loads and thermal effects can be identified.

Originality/value

This paper provides novel insight into the (sometimes counter-intuitive) behaviour of beams exposed to fire, highlighting trends and the influence of important input parameters on predicted response.

Abstract

Purpose

The purpose of this paper is to investigate a dissipative reinforced concrete structural wall that can improve the behavior of a tall multi-storey building. The main objective is to evaluate the damage of a dissipative wall in comparison with that of a solid wall.

Design/methodology/approach

In this paper, a comparative nonlinear dynamic analysis between a dissipative wall and a solid wall is performed by means of SAP2000 software and using a layer model. The solution to increase the seismic performance of a reinforced concrete structural wall is to create a slit zone with short connections. The short connections are introduced as a link element with multi-linear pivot hysteretic plasticity behavior. The behavior of these short connections is modeled using the finite element software ANSYS 12. In this study, the authors propose to evaluate the damage of reinforced concrete slit walls with short connections using seismic analysis.

Findings

Using the computational model created in the second section of the paper, a seismic analysis of a dissipative wall from a multi-storey building was done in the third section. From the results obtained, the advantages of the proposed model are observed.

Originality/value

A simple computational model was created that consume low processing resources and reduces processing time for a dynamic pushover analysis. Unlike other studies on slit walls with short connections, which are focussed mostly on the nonlinear dynamic behavior of the short connections, in this paper the authors take into consideration the whole structural system, wall and connections.

Abstract

Purpose

Due to the enormous increase in economic development, structural steel material gives an advantage for the construction of stadiums, factories, bridges and cities building design. The purpose of this study is to investigate the behaviour of bending, buckling and torsion for I-beam steel section with and without web opening using non-linear finite element analysis.

Design/methodology/approach

The control model was simulated via LUSAS software with the four main parameters which included opening size, layout, shape and orientation. The analysis used a constant beam span which is 3.5 m while the edge distance from the centre of the opening to the edge of the beam is kept constant at 250 mm at each end.

Findings

The analysis results show that the optimum opening size obtained is 0.65 D while optimum layout of opening is Layout 1 with nine web openings. Under bending behaviour, steel section with octagon shapes of web opening shows the highest yield load, yield moment and thus highest structural efficiency as compared to other shapes of openings. Besides, square shape of web opening has the highest structural efficiency under buckling behaviour. The lower buckling load and buckling moment contribute to the higher structural efficiency.

Originality/value

Further, the square web opening with counter clockwise has the highest structural efficiency under torsion behaviour.

Abstract

This chapter introduces the Person-in-Environment (PIE) framework, a research design and a nationwide empirical study, developed by the author, to measure the relative impacts of socio-structural and personal factors on individual-level information behaviours (IB) and outcomes. The IB field needs to tackle two questions: (1) In a particular situation, how much of an individual's IB is influenced by personal characteristics? and (2) How much of this behaviour is shaped by one's environment, such as socio-structural barriers? PIE is a beginning effort to address this agency–structure debate, which is a topic that confronts many social scientists. This chapter first outlines IB research relevant to agency–structure integration. It then presents six principles of the PIE framework. Personal characteristics (e.g. cognitive and affective factors) and socio-structural factors (e.g. information resources distribution) are conceptualised as interrelated. Thus, these need to be tested simultaneously. Previously, it was difficult to link individual- and societal-level datasets because their units of observation often vary. To overcome these methodological challenges, this author purposed a research design that employs secondary analysis, geographic information systems techniques and structural equation modelling. An empirical study of the library usage by 13,000 American 12th graders is presented to demonstrate PIE's applicability. Discussions on the future directions of PIE studies conclude the chapter. The PIE framework can contribute to conceptual and methodological development in IB research. It also offers scholars and policymakers a way to empirically assess the contributions of information services on an individual's life, while taking personal differences into account.

Abstract

Purpose

The purpose of this paper is to set up a comprehensive numerical approach to estimate the 3D structural vibration and noise radiation of an induction machine.

Design/methodology/approach

The rotating force waves, acting in the air gap of an induction machine and obtained by an electromagnetic finite element multi‐slice simulation, are applied to the 3D structural finite element model and a structural harmonic simulation is performed. The sound emission due to the vibration of the surface of the machine is computed with a 3D boundary element model.

Findings

The paper outlays problematic issues when setting up the numerical models, i.e. the structural finite element model. The material properties strongly affect the structural behaviour and therefore the radiated noise.

Originality/value

The 3D force distribution in the air gap and the resulting vibrations are computed. The structural behaviour, i.e. the different vibrational behaviour of stator and surface is discussed. The correlation of the structural vibrations and the noise radiation is investigated.
