Abstract

Purpose

The purpose of this study is to create a knowledge base for decision-making in healthcare design by seeking, analyzing and discussing the preferences of facility managers of healthcare facilities regarding floor finishes and their selection criteria. The goal is to enable a simplified and holistic selection of floor finishes based on multiple criteria. The authors studied floor finish selection in three healthcare units: emergency, surgery and in-patient units.

Design/methodology/approach

The authors completed a literature review to identify types of floor finishes currently used in healthcare facilities and the criteria applied for their selection. Using the literature survey results, a questionnaire was designed and administered to healthcare facility managers. The descriptive statistical analysis and the Friedman and Wilcoxon signed-ranks tests were used for reporting and analyzing the survey data.

Findings

The top five floor finishes used in the healthcare sector were identified as vinyl flooring, vinyl composite tile (VCT), rubber, linoleum and ceramic flooring. The top five selection criteria for floor finishes were durability, infection control, ease of maintenance, maintenance cost and user safety. The non-parametric test results show that the floor finish rankings and selection criteria were similar in the three healthcare units under study.

Originality/value

The most significant contribution of this research is to the design decision-making process of healthcare facilities. These results offer an understanding of what floor finishes are preferred by healthcare facility managers and why. This knowledge is crucial for designers and facility managers to make informed choices and floor finish manufacturers to keep their product line relevant to the industry.

Abstract

Purpose

The purpose of this paper is to discuss the results of the first four years of implementation of a quality program called “Quality Contest” (QC). This program was implemented from 2007 onward to improve the quality of hospital services by the Moroccan Ministry of Health. The peculiarity of this intervention, held every 18 months, is that it combines several approaches (self-evaluation, external audits with feedback, hospital ranking, awards and performance disclosure) and focuses on the quality of management.

Design/methodology/approach

The assessment tool used to evaluate the quality of hospital management consists of 80 items. In each contest, a score is attributed to each item based on the score given for self-evaluation and the score given by external auditors. The sum of these scores allows the global performance score of the hospital to be obtained. To compare the performances over time and among hospitals, Wilcoxon signed-rank, Wilcoxon–Mann–Whitney and Kruskal–Wallis statistical tests were used.

Findings

The results of the QC organized between 2007 and 2010 revealed that the hospitals participating in all the three contests had significantly improved their performance levels in terms of the quality of management. There was also a significant association between the number of times hospitals participated in the QC and the performance scores attained.

Originality/value

The paper reports an original quality improvement approach in a developing country that succeeded in triggering sustainable improvement dynamics by combining support (feedback) with reward (prizes) and pressure measures (ranking, performance disclosure).

Abstract

Purpose

Cataract surgery is a highly successful, high‐volume surgery, hence reducing surgical complications are imperative for organizations to deliver cost‐effective, high‐quality services that meet the needs of patients. This paper aims to describe 18‐month results of a sustainable program to maximize the safety of cataract surgery training.

Design/methodology/approach

Modifications to the comprehensive cataract‐training program and tested were developed in a controlled, interventional case series to evaluate their effect on trainee complication rates. Data collection and interpretation were performed in a prospective and blind manner.

Findings

Prior to intervention, PCR rates for trainee‐surgeons averaged 3.34 per cent cf international published figures of 4.6‐10 per cent. This compared with 1.89 per cent PCR rate for trained cataract surgeons (p<0.002, Mann Whitney test). Multiple interventions were introduced and enforced to maximize cataract surgery training safety. After 18 months follow‐up data were consistent with a statistically significant reduction in trainee PCR rates (1.53 per cent, p<0.007, Wilcoxon Signed Ranks test) compared with trained cataract surgeons (1.23 per cent, p<0.074, Wilcoxon Signed Ranks test). Parameters of training efficacy were improved or maintained during this period.

Research limitations/implications

Limitations included using trained cataract surgeons as controls as apposed to a similar group of trainee surgeons. In addition, multiple interventions were simultaneously instituted, making identification of a single influential factor impossible to identify.

Practical implications

Maximally safe and effective cataract surgery training is achieved in Singapore without compromising service and quality markers. Similar training goals can be extrapolated to other surgical disciplines.

Originality/value

This is the first study to demonstrate maximally safe and effective cataract surgery training in a large patient group, over sustained periods.

Abstract

Purpose

This study aims to investigate and explore the impact of big data analytics (BDA) as a mechanism that could develop the ability to measure customers’ performance. To accomplish the research aim, the theoretical discussion was developed through the combination of the diffusion of innovation theory with the technology acceptance model (TAM) that is less developed for the research field of this study.

Design/methodology/approach

Empirical data was obtained using Web-based quasi-experiments with 104 Egyptian accounting professionals. Further, the Wilcoxon signed-rank test and the chi-square goodness-of-fit test were used to analyze data.

Findings

The empirical results indicate that measuring customers’ performance based on BDA increase the organizations’ ability to analyze the customers’ unstructured data, decrease the cost of customers’ unstructured data analysis, increase the ability to handle the customers’ problems quickly, minimize the time spent to analyze the customers’ data and obtaining the customers’ performance reports and control managers’ bias when they measure customer satisfaction. The study findings supported the accounting professionals’ acceptance of BDA through the TAM elements: the intention to use (R), perceived usefulness (U) and the perceived ease of use (E).

Research limitations/implications

This study has several limitations that could be addressed in future research. First, this study focuses on customers’ performance measurement (CPM) only and ignores other performance measurements such as employees’ performance measurement and financial performance measurement. Future research can examine these areas. Second, this study conducts a Web-based experiment with Master of Business Administration students as a study’s participants, researchers could conduct a laboratory experiment and report if there are differences. Third, owing to the novelty of the topic, there was a lack of theoretical evidence in developing the study’s hypotheses.

Practical implications

This study succeeds to provide the much-needed empirical evidence for BDA positive impact in improving CPM efficiency through the proposed framework (i.e. CPM and BDA framework). Furthermore, this study contributes to the improvement of the performance measurement process, thus, the decision-making process with meaningful and proper insights through the capability of collecting and analyzing the customers’ unstructured data. On a practical level, the company could eventually use this study’s results and the new insights to make better decisions and develop its policies.

Originality/value

This study holds significance as it provides the much-needed empirical evidence for BDA positive impact in improving CPM efficiency. The study findings will contribute to the enhancement of the performance measurement process through the ability of gathering and analyzing the customers’ unstructured data.

Abstract

Purpose

Generator maintenance scheduling (GMS) is an essential task for electric power utilities as the periodical maintenance activity enhances the lifetime and also ensures the reliable and continuous operation of generating units. Though numerous meta-heuristic algorithms have been reported for the GMS solution, enhancing the existing techniques or developing new optimization procedure is still an interesting research task. The meta-heuristic algorithms are population based and the selection of their algorithmic parameters influences the quality of the solution. This paper aims to propose statistical tests guided meta-heuristic algorithm for solving the GMS problems.

Design/methodology/approach

The intricacy characteristics of the GMS problem in power systems necessitate an efficient and robust optimization tool. Though several meta-heuristic algorithms have been applied to solve the chosen power system operational problem, tuning of their control parameters is a protracting process. To prevail over the previously mentioned drawback, the modern meta-heuristic algorithm, namely, ant lion optimizer (ALO), is chosen as the optimization tool for solving the GMS problem.

Findings

The meta-heuristic algorithms are population based and require proper selection of algorithmic parameters. In this work, the ANOVA (analysis of variance) tool is proposed for selecting the most feasible decisive parameters in algorithm domain, and the statistical tests-based validation of solution quality is described. The parametric and non-parametric statistical tests are also performed to validate the selection of ALO against the various competing algorithms. The numerical and statistical results confirm that ALO is a promising tool for solving the GMS problems.

Originality/value

As a first attempt, ALO is applied to solve the GMS problem. Moreover, the ANOVA-based parameter selection is proposed and the statistical tests such as Wilcoxon signed rank and one-way ANOVA are conducted to validate the applicability of the intended optimization tool. The contribution of the paper can be summarized in two folds: the ANOVA-based ALO for GMS applications and statistical tests-based performance evaluation of intended algorithm.

Abstract

Purpose

Companies that adopt lean operations and lean accounting ultimately should achieve better profitability and cash flows than similarly situated companies that do not adopt lean operations and lean accounting.

Methodology

Archival data is analyzed through Wilcoxon signed-ranks, matched-pairs tests.

Findings

Lean companies had greater returns on net operating assets (RNOA), returns on total assets (ROA), operating cash flows, and cash-adequacy ratios than Non-Lean companies. These results were driven by the larger Lean companies. The profit margins and financing-assets ratios also were marginally better for the Lean companies than the Non-Lean companies.

Implications

Lean companies have achieved benefits proposed by the proponents of lean operations. The present study provides a starting point for further research on the financial performance of Lean companies using archival data.

Originality/value

There is limited research on the financial performance of Lean companies that is based on archival data. The present study fills a void in the academic literature. This study measures RNOA, which does not confound operating and financing activities. Additionally, this study utilized a methodology that provides reasonable assurance of the identification of both Lean companies and Non-Lean companies from publicly available data.

Abstract

Purpose

The aim of this paper was to compare university students’ preferences for searching the library catalogue via the library’s Koha online public access catalogue (OPAC) or its discovery tool VuFind.

Design/methodology/approach

A total of 175 students responded to a questionnaire-based survey through which their demographic data, duration (years) of computer use and their self-reported levels of computer skills were obtained. Students were asked what interfaces they use for catalogue searching and to rate their opinion on the relevant interfaces on a seven-point Likert scale. Mann–Whitney and Kruskal–Wallis tests were conducted to statistically compare the differences between students’ demographic/individual characteristics and their ratings on the respective interfaces. For those students who used both systems, differences between their Likert ratings were assessed using a one-tailed Wilcoxon signed rank test.

Findings

The results showed that there were no significant differences among students in terms of their ratings on either the OPAC or VuFind interfaces. Wilcoxon signed ranks test indicated that significantly more students thought that VuFind was more usable than the Koha OPAC.

Originality/value

This is a pioneering study of the current use of the OPAC and discovery tools by university students and their preferences for searching catalogue information through these systems. It is hoped that the findings of this study will encourage researchers to conduct task-based usability studies with various cataloguing tools and this could yield new and improved interaction designs for library catalogue searching.

Abstract

Purpose

The main purpose of this paper is to describe the use of e-resources at Jawaharlal Nehru University (JNU), those are being offered through the University Grant Commission – Information and Library Network (UGC-INFONET) consortium. Statistical techniques are applied on usage reports generated by e-resources vendors/publishers to understand trend and seasonality in usages of e-resources in academic libraries. The researchers evaluated gain in popularity of e-resources and drew a comparison in use of various databases of e-resources in terms of volume of downloads over a period of three years. The study would help in designing an instrument to evaluate utilization of e-resources. The cross comparison of databases helps in identifying e-resources, which have been optimally used.

Design/methodology/approach

The present study used quantitative approach to express utilization of e-resources in terms of number of downloads of full text research papers from Project Muse, Cambridge University Press, Oxford University Press, Springer Links, Taylor and Francis and JSTOR databases, accessible through the UGC-INFONET consortium. The investigation is based on secondary data of usage statistics made available by the UGC-INFONET consortium. The descriptive statistics techniques have been used in the initial phase of the investigation to understand trend in utilization of e-resources and examine robustness of various statistical tests to identify most appropriate tests for the latter phase of the investigation. The robustness analysis has been recommended for graphical and non-parametric tests for advanced investigation, in the latter phase of the study. The with-in cohort analysis techniques investigates numbers of monthly downloads from each database for a period of three years, i.e. 2008-2010 to explain seasonality in volume of downloads of e-resources.

Findings

e-Resources have been gaining popularity gradually in academic libraries; this trend is in tune with gaining of popularity of web-based intellectual resources in other sectors. The study established need of library consortium for sharing resources and subscription fee. The investigation proves significant association between numbers of downloads of e-resources from different databases in the same period; thus gain in popularity of one database encourages readers to explore other databases. The study indicates seasonality effect in the usages of e-resources in academic libraries. This seasonality effect is contemporary to the academic calendar. There are large numbers of downloads just before the examinations, which are held twice in a year and negligible number of downloads during and around long summer study breaks. Thus, the bandwidth rendered to the university is not consistently used during the academic session. The coverage of databases in terms of disciplines and numbers of journals varies to great extent. There is overlapping in the coverage of databases. The strength of students and their demands for scholarly works also vary across disciplines, thus cross comparison of numbers of downloads from databases has little meaning until impact of these three parameters are not controlled in the investigation of utilization of e-resources.

Originality/value

The literature shows that no study has been carried out for the use of e-resources by researchers of JNU.
