Abstract

Purpose

The purpose of this paper is to explore the sources of inspiration for active participants in sport events, and the link between inspiration sources and event-related outcomes (i.e. life satisfaction and behavioral intentions).

Design/methodology/approach

Research questions were examined using a Greek (n=264) and a US (n=103) sample of participants of two small-scale running events. Content analysis was used to identify and code the themes of inspiration, while a multivariate analyses of variance was performed to test the inspiration group differences on life satisfaction and behavioral intentions.

Findings

The qualitative findings revealed three categories of inspiration source identified in each sample. The quantitative results showed that the interaction between inspiration source and event type had an overall effect on participants’ life satisfaction and future participation intention. Specifically, findings highlighted the different roles of inspiration on influencing life satisfaction and participation intention of short-distance (i.e. 5 and 10k) event participants than those of long-distance (i.e. marathon) runners.

Research limitations/implications

This study identifies the sources of inspiration in small-scale sport events and provides preliminary empirical evidence where inspiration source and event type jointly influence participants’ life satisfaction and behavioral intentions.

Practical implications

Understanding the sources of inspiration provides event leveraging opportunities to inspire citizens to become more active in sports. Given that the sources of inspiration vary among different segments of event participants, event managers need to adopt differential communication and promotional activities geared to the needs of these targets.

Originality/value

The study provides the first empirical work exploring the sources of inspiration among active participants in small-scale sport events.

Abstract

Purpose

The purpose of this paper is to study the dynamic features of friction coefficient during running-in state based on recurrence analysis, so as to recognize the running-in state of crankshaft journal bearings.

Design/methodology/approach

The friction coefficient was measured in the friction experiments and the dynamic features are analyzed by recurrence plots (RPs), unthreshold recurrence plots (URPs) and recurrence quantification analysis.

Findings

During the running-in process, RPs have gone through disrupted patterns, drift patterns and homogeneous patterns successively. URP shows that the phase trajectory spirals in the disrupted pattern gradually converge in the drift pattern and remain stable in the homogeneous pattern. Three independent measures, recurrence rate, entropy and laminarity, are chosen to characterize friction coefficient from the perspective of point, diagonal line and vertical line structures of the RPs.

Originality/value

The results provide a feasible way to monitor the running-in process and recognize the running-in state.

– The purpose of this paper is to examine some factors that influence the intensity of fertilizer use in Malawi.

Abstract

Purpose

The purpose of this paper is to examine some factors that influence the intensity of fertilizer use in Malawi.

Design/methodology/approach

The study uses Engle-Granger, Engle-Yoo three steps and autoregressive distributed lags (ARDLs) approaches to examine the long-run and the short-run dynamics among the variables using annual data from 1961 to 2006.

Findings

The econometric results indicate that all the variables exert significance influence on the quantity of fertilizer demanded excluding population growth, while the results of the short-run model indicate that the responsiveness of fertilizer demand to all the variables is significant.

Research limitations/implications

Although, this study has provided some helpful results in understanding the major factors responsible for low fertilizer consumption in the study but some time series data on important factors are lacking.

Originality/value

The work is different from already existing literature in Malawi. The authors included subsidy and real gross domestic product to account for the effect of macroeconomic shocks and policies, which has not been accounted for by other related empirical studies. Moreover, this study used ARDLs techniques that can overcome the problem of insufficiently long time series data which is a significant contribution to the existing literature.

Abstract

Purpose

The objective of this paper is to determine fretting parameters of hoisting rope according to the hoisting parameters in coalmine and to explore the effect of contact load on fretting-fatigue behavior of steel wires.

Design/methodology/approach

Based on the mechanical model of hoisting rope in coalmine, the dynamic tension simulation of hoisting rope was performed. Static equations of hoisting rope under tension and torsion and theories of contact mechanics were applied to obtain fretting parameters. Fretting-fatigue tests of steel wires at different contact loads were conducted using a fretting-fatigue test rig. The fretting regime, normalized tangential force and fretting-fatigue life were studied. The morphologies of fretting contact scars and fracture surfaces were observed by scanning electron microscopy and optical microscopy to examine wear and failure mechanisms.

Findings

Dynamic tension changes from 0 to 30,900 N. In outer strand layer, contact loads between steel wires in certain wire layers are 60.5 and 38.3 N compared with 378 and 102.7 N between wire layers; relative displacements between wires are 62.5 and 113.2 μm, respectively. Mixed fretting regimes develop in all cases. Increasing contact load decreases the stabilized relative slip and normalized tangential force, reduces the fretting fatigue life, induces accelerated adhesive wear and fatigue wear and results in rougher fracture surface topographies. In all cases, fretting zone induces crack initiation; crack propagation and rupture zones present brittle cleavage and longitudinal splitting, respectively.

Practical implications

This paper presents the systemic study on determination of fretting parameters of hoisting rope according to the hoisting parameters in coalmine and the fretting-fatigue behavior of its internal steel wires. The results of fretting-fatigue tests show that the increase of contact load decreases the stabilized relative slip in mixed fretting regime and normalized tangential force, reduces the fretting fatigue life, induces accelerated adhesive wear and fatigue wear and results in rougher fracture surface topographies.

Originality/value

The authors warrant that the paper is original submission and is not being submitted to any other journal. And the research does not involve confidentiality, copyright infringement, leaks and other issues, all the responsibilities that the authors will take.

The purpose of this paper is to find the event memory characteristics hidden in trade data.

Abstract

Purpose

The purpose of this paper is to find the event memory characteristics hidden in trade data.

Design/methodology/approach

First, historical trade data are analyzed to define the events described by multi‐dimensional characteristic variables. The variables containing information are employed to build the event description patterns. Furthermore, a search engine is developed for calendar events, which can search for events in historical data and produce a collection of events. The search engine also extracts relevant system reaction phenomena described by trend distribution for each event pattern. Finally, both event patterns and system reactions construct the episodic memory model.

Findings

The event patterns and the system reactions are used to define the episodic memory model. The search methods for the episodic memory model obtained from trade data set are given.

Research limitations/implications

Accessibility and availability of data are the main limitations affecting where the method can be applied.

Practical implications

The method is helpful for traders when judging the current trade situation from historical memory.

Originality/value

The paper presents a new episodic memory modeling method based on trade data.

Abstract

Purpose

The purpose of this paper is to examine the following research question in partner selection decisions in business-to-business strategic partnerships/collaborations literature: How do inertia and uncertainty affect partner selection? Explicitly, the paper analyzes how inertia of previous alliance selection routines and uncertainty of entire market movement shape firms’ preferences regarding exploratory partner selection (i.e. selecting new partners who never collaborate with the focal firm).

Design/methodology/approach

Grounded on inter-firm partnerships, partner selection and network theory literature, the study empirically tests a fine-grained sample of 511 open-end funds initiated by 61 fund management firms in China. To do so, it runs Tobit regression for main analysis and applies a variety of sensitivity analyses to check the robustness.

Findings

Results show that inertia in previous partner selection has a negative effect on exploration. Importantly, these inertial forces impact domestic firms but not international firms. Market uncertainty also affects exploratory partner selection: short-term market uncertainty encourages exploration, whereas long-term uncertainty inhibits it. These effects also depend on firms’ type: long-term market uncertainty has a negative effect on exploration for international firms but not for domestic firms. Both types of firms exhibit a stronger tendency toward exploration when they encounter short-term uncertainty. However, this inclination is stronger in international firms.

Originality/value

Earlier research has examined how inertia affects exploitation but largely overlooked its effect on exploration. A critical examination of firm and environment level factors provides a deeper understanding of why and when firms have inconsistent preferences for specific partner selection strategies. Thus, this study offers a unique perspective for understanding firms’ exploratory partner selection by focusing on two important characteristics of focal firms: one internal (inertia) and one external (market uncertainty) in nature.

Abstract

Purpose

The purpose of this study is to develop and test a theoretical framework to examine business purchase decisions using the concept of “values” (personal values (PV), organizational values (OV) and values-congruency).

Design/methodology/approach

The data for the study were collected from members of the Supply Chain Management Association of Canada. The relationships between perceived PV/OV/ values-congruency (IVs) and perceived role values played in business purchase decisions (DV) were hypothesized. Three factors, namely, humanity, bottomline and convention were identified using exploratory factor analysis. The hypotheses were tested using polynomial regression, which is a preferred method for measuring congruency or fit (Edwards, 1994).

Findings

Perceived humanity (humaneness or benevolence) values of an organization were found to have a positive relationship with the perceived role that humanity and convention (risk aversion or compliance) values played in business purchase decisions. Perceived purchase function formalization within buying organizations was also found to have a positive relationship with the perceived role of humanity, bottomline and convention values played in business purchase decisions.

Research limitations/implications

The study drew a relatively small convenience sample from a single industry association/country with a low response rate. It used the perceived role of values instead of behavioral intention or actual behavior to measure business purchasing behavior. McDonald and Gandz’s (1991; 1993) list of values may be more suitable to measure OV than PV. The study only considered the buyer side of purchase decisions and values to have positive characteristics.

Practical implications

Buying organizations may consider formalizing their purchase functions, clarifying their humaneness/benevolence and risk aversion/compliance values to their employees and vendors and incorporating them in the purchasing criteria/process. Similarly, selling organizations may benefit from considering these values of customers to position their products and services for better sales outcomes and business relationships.

Originality/value

The study explores the role of values in business purchase contexts by proposing and testing a theoretical framework. The study has implications for practitioners and academics in the field and identifies several areas for future research.

Abstract

Purpose

This paper aims to investigate the effects of various heat treatments on microstructure, hardness, porosity and corrosion properties of the parts.

Design/methodology/approach

Hot isostatic pressing (HIP) process, various heat treatments and their combinations were applied to the AlSi10Mg parts produced by direct laser metal sintering (DMLS).

Findings

It has been found that the HIP process, which is a post-processing process, reduces the amount of porosity in DMLS-AlSi10Mg material, thus improves corrosion resistance significantly.

Originality/value

In this study, the HIP process and subsequent T6 heat treatments were applied to AlSi10Mg parts produced by the DMLS technique. The study aims to increase the corrosion resistance of AlSi10Mg parts by reducing porosity with the HIP process and by altering the microstructure with the T6 process.

Abstract

Purpose

This study aims to analyze the dynamic performance of aerostatic thrust bearing for different geometries of recess. Different geometries of recess of equal recess area, i.e. circular, elliptical, rectangular and annular, have been considered in analysis. The work also analyzes the influence of tilt angle on the performance of thrust bearing. To compute the unknown pressure field, the Reynolds equation governing the flow of compressible lubricant (air) has been solved using finite element formulation. Further, separate finite element formulations have been carried out to compute fluid film stiffness and damping coefficients directly. This method provides quick computation of stiffness and damping coefficients of aerostatic thrust bearing than the usual approach.

Design/methodology/approach

As the Reynolds equation governing the flow of compressible lubricant is nonlinear partial differential equation, the computation of the stiffness and damping coefficient follows an iterative procedure. It requires a lot of computational energy. Therefore, in the present work, a novel technique based on finite element formulation is suggested to compute air film stiffness and damping coefficient in aerostatic thrust bearing.

Findings

A novel technique based on finite element formulation is illustrated to simulate the performance of tilted pad aerostatic thrust bearing. On the basis of simulated results, following key conclusions may be drawn. The static and dynamic performance of a circular aerostatic tilted thrust pad bearing is significantly affected with a change in the value of tilt parameter and the shape of the recess.

Research limitations/implications

Implications are as follows: direct computation of air film damping coefficient is performed without perturbation method in finite element method (FEM); influence of tilt on aerostatic thrust bearing is studied; influence of recess shape on aerostatic thrust bearing is observed; and finite element formulation of aerostatic thrust bearing is performed.

Originality/value

The present work will be quite useful for bearing designer and academicians.
