Abstract

Purpose

The aim of this paper is to extend the knowledge of the link between job insecurity and job performance by exploring potential mediating mechanism of psychological strains and moderation role of psychological advantages on the mentioned relationship in the hospitality industry.

Design/methodology/approach

A sample of 288 frontline employees from five and four star hotels in north Cyprus was selected through judgmental sampling. Structural equation modeling was used to investigate the research model, and hierarchal multiple regression was used to test forwarded hypotheses.

Findings

The results showed that Job Insecurity mitigates Job Performance. The results further suggested that anxiety, as a psychological strain, mediates the effect of job insecurity on job performance. Additionally, psychological advantages (supervisor support and intrinsic motivation) play a crucial role as a delimiter against the negative effect of job insecurity on job performance.

Research limitations/implications

Hotel managers need to establish and communicate transparent human resource polices including, win-win-based employee contracts, fair selection, placement, appraisal, compensation, reward and similar human resource systems within hotels. Empowering and developing relations skills between supervisors and employees by providing continued training programs are vital for minimizing organizational stress and anxiety from job insecurity. Keeping in mind high employee turnover rates in the industry and its considerable costs, especially intrinsically motivated employees willing to work long hours should be selected in those organizations. Additionally, buddy-buddy approach in mentoring can be used by well-selected senior employees to help new employees socialize, improve their performance via social support and retain them in the end. By implication, lacking time lag is considered as the limitation.

Originality/value

Empirical research relating to the psychological strains and leverages of job insecurity is sparse in the hospitality industry. Based on job demand-resource and conservation of resource theories, the present research aimed to fill this gap.

Abstract

Purpose

This paper aims to study how the trajectory of fundamental values affects price discovery in an experimental asset market.

Design/methodology/approach

An experiment is conducted with two treatments, in which the time path of fundamentals differs between treatments. In the peak treatment, fundamentals first rise and then fall, while in the valley treatment fundamentals first fall and then recover. The experiment allows market prices to be compared to fundamental values.

Findings

Both peak and valley treatments experience bubbles when traders are inexperienced. However, price discovery is more rapid and complete in the peak than in the valley treatment. In the peak treatment, prices track the value, the direction of the trend, and changes in trend, more closely than in the valley treatment.

Originality/value

This paper documents the first experimental results regarding pricing behavior in markets with non‐monotonic fundamentals. It creates an environment (the valley treatment) in which convergence to close to fundamentals does not occur even with repetition of the market under identical conditions. The results demonstrate that the likelihood that an asset market tracks fundamentals depends on the time path of fundamentals.

Abstract

Purpose

With the rapid development of e-commerce, multi-sourcing with supply contracts and spot buying has become more and more popular in reality. The main purpose of the paper is to explore a loss-averse buyer's optimal procurement policy in a multi-sourcing under e-commerce surroundings.

Design/methodology/approach

The study introduces the loss aversion utility function to characterize the loss aversion effect and derives a loss-averse buyer's optimal procurement policy in a multi-sourcing with a wholesale price contract and spot market.

Findings

A loss-averse buyer could order no items in a wholesale price contract and only needs to replenish commodities from spot market under certain conditions. In addition, the study shows that spot capacity has important influences on a loss-averse buyer's optimal ordering decision in the wholesale price contract.

Originality/value

This is the first paper to study the loss aversion effect on a buyer's procurement decision in a multi-sourcing. The results present important managerial insights for a loss-averse buyer to devise optimal ordering policies in a multi-sourcing under e-commerce surroundings.

Abstract

This study examined the information sources that golfers used to purchase golf clubs. Three personal references (family, friends and salespeople) and five non-personal references (television, newspaper, magazine, product catalogue and the internet) were examined from a total of 626 randomly selected golfers in the US. Approximately 85% of the golfers stated that their primary information sources for purchasing golf clubs were personal references. The results suggest that a marketing strategy should place more emphasis on personal sources than non-personal sources.

Abstract

Purpose

The purpose of this study is to explore a signal processing method to improve the angular rate accuracy of micro-electro-mechanical system (MEMS) gyroscope by combining numerous gyroscopes.

Design/methodology/approach

To improve the dynamic performance of the signal processing method, the interacting multiple model (IMM) can be applied to the fusion of gyroscope array. However, the standard IMM has constant Markov parameter, which may reduce the model switching speed. To overcome this problem, an adaptive IMM filter is developed based on the kurtosis of the gyroscope output, in which the transition probabilities are adjusted online by utilizing the dynamic information of the rate signal.

Findings

The experimental results indicate that the precision of the gyroscope array composed of six gyroscopes increases significantly and the kurtosis-based adaptive Markov parameter IMM filter (K-IMM) performs better than the baseline methods, especially under dynamic conditions. These experiments prove the validity of the proposed fusion method.

Practical implications

The proposed method can improve the accuracy of MEMS gyroscopes without breakthrough on hardware, which is necessary to extend their utility while not restricting the overwhelming advantages.

Original/value

A K-IMM algorithm is proposed in this paper, which is used to improve the angular rate accuracy of MEMS gyroscope by combining numerous gyroscopes.

Abstract

Purpose

The purpose of this paper is to propose an integrated fuzzy approach to determine important universal usability problems (UUPs) by providing experts who behave like real users and to establish a work plan to correct the most important ones.

Design/methodology/approach

In this study, a fuzzy multi-criteria decision-making approach with three stages is proposed for the evaluation of universal usability. At the first stage, UUPs are identified by performing modified heuristic evaluation, and severity rating of each problem is determined by experts. At the second stage, critical problems are specified by applying the fuzzy Delphi considering these severity ratings. At the third stage, Fuzzy Decision Making Trial and Evaluation Laboratory approach is applied to prioritize critical problems as sub and main criteria. An illustrative example related to emergency service is performed to apply the proposed approach.

Findings

Results showed that the elevator button design, the elevator emergency button design and the position of the floor signboard are the first three problems that should be primarily improved as sub-criteria. In terms of main criteria, equitable use, simple and intuitive use, and perceptible information are the first three main criteria that should be improve in emergency service.

Originality/value

This study is original in terms of methodology and providing a new perspective for building design evaluation. The results can help the designers to see the UUPs in buildings, to focus the most important UUPs and to establish improvement ranking. These advantages provide time and cost-effective design improvement actions.

Abstract

Purpose

Optimal ordering decision for a retailer in a dual-sourcing procurement is an important research area. The main purpose of this paper is to explore a loss-averse retailer’s ordering decision in a dual-sourcing problem.

Design/methodology/approach

For a loss-averse retailer, the study obtains the optimal ordering decision to maximize expected utility. Based on sensitivity analysis, the properties of the optimal ordering decision are well discussed.

Findings

Under the optimal ordering quantity that maximizes expected loss aversion utility, the relevant expected profit of a retailer turns to be smaller under a bigger loss aversion coefficient. For this point, a retailer needs to balance between expected loss aversion utility maximization and expected profit maximization in deciding the optimal ordering policy in a dual-sourcing problem.

Originality/value

This paper reveals the influence of loss aversion on a retailer’s ordering decision in a dual-sourcing problem. Managerial insights are suggested to devise the optimal ordering policy for retailers in practice.

Abstract

This chapter is concerned with the estimation of spillover effects when outcomes arise as a consequence of bilateral interactions instead of from individual actions. In this type of environments, outcomes are generated on links instead of on nodes of a network, like bilateral prices in over-the-counter markets. The author proposes a link-based spatial autoregressive (SAR) model and discusses identification conditions and a two step least square estimation procedure. The author shows analytically that using a standard node-based SAR, which models nodes instead of links’ outcomes, produces misleading results when the data generating process is link-based. The methodology is illustrated using Monte Carlo experiments and real data from an interbank network.

Abstract

Purpose

The objective of this work is to develop a model that can be used for simulation of different parameters including price, subjected to different control strategies.

Design/methodology/approach

The entire supply chain can be modelled by combining the transfer function into a closed loop system. The transfer function of each entity in the supply chain can be obtained by using the control theory tools. The model can be approximated as a linear discrete system with various operating constants, like lead time, price, order policy and supply.

Findings

The continuous replenishment ordering policy for a distribution node in a supply chain was analyzed using the z-transform. Characteristic equations of the closed loop transfer function are obtained. The bullwhip (BW) effect is analyzed. Study proves that the BW effect is in evitable if the standard heuristic ordering policy is employed with demand forecasting; also the paper analysed price supply trade-off for dynamic demand and supply. Simulation results show that BW is less in PI and simple p-only with cascade control. Robust control and PD, PID control results are not shown in this literature, and it is subject to further research.

Originality/value

Research is original, it can be applicable in today's dynamic world, due to globalization, it is necessary to have a automated machine that can handle most of supply chain decision.
