Abstract

We consider the problem of assigning ship assembly blocks to storage locations at a ship yard while allowing one-way movement of the blocks. The objective is to minimize the number of blocks obstructing other blocks’ movements. We show that the integer program in a previous study contains errors in identifying obstructive blocks and therefore, suggest another integer program without the error. Also, we suggest construction heuristics and a tabu search algorithm using properties characterizing optimal solutions of subproblems. Computational experiment results indicate that our heuristics outperform the existing algorithm in terms of solution quality.

Abstract

Purpose

While there is ample discussion in management studies and organizational behavior textbooks about the factors that impact organizational outcomes, such as employee retention, this research is focused on exploring the previously unexplored question of how procedural justice, job characteristics and meaningful work influence employees' intentions to leave their organizations. As such, this study aims to investigate the impact of procedural justice on employees' intentions to leave, both independently and in conjunction with job characteristics and meaningful work as mediators.

Design/methodology/approach

This study uses partial least squares structural equation modeling (PLS-SEM) to develop the research model and for hypothesis testing. The path model is assessed using critical model fit indices and measures of goodness of fit.

Findings

The results reveal a negative relationship between procedural justice and employees’ intentions to leave. This negative relationship persists and is strengthened when both job characteristics and meaningful work act as mediators. Although job characteristics only exerted a significant effect through indirect effects, meaningful work demonstrated a significant negative impact on the intentions to leave through both direct and indirect effects.

Originality/value

This study presents a new perspective on employee retention by proposing an original mediation-based path model. Through the testing of eleven hypotheses, the study reveals the intricate relationships between the four constructs examined. The findings provide valuable insights that can serve as a basis for future research in management studies and organizational behavior.

Abstract

Many problems occur when assigning tasks to work centres, especially in determining the required number of workstations for line balancing which requires a minimum theoretical number of workstations. The most common problem is bottleneck. In this paper, a method is proposed to solve floating tasks problem in single-model line when the actual required number of workstations exceeds the minimum theoretical number, and the standard time of the floating task (work center) exceeds the cycle time. The floating task will represent a critical bottleneck activity in line. The proposed method depends on minimizing the standard time of critical bottleneck and non-critical activities by a minimum free-floating time depends on the average of slack times of the non-critical activities, and it will increase the line efficiency from (77%) to (88%), and balance delay is minimized from (23%) to (12%).

Abstract

Purpose

The authors constructed an automatic essay scoring (AES) model in a discussion forum where the result was compared with scores given by human evaluators. This research proposes essay scoring, which is conducted through two parameters, semantic and keyword similarities, using a SentenceTransformers pre-trained model that can construct the highest vector embedding. Combining these models is used to optimize the model with increasing accuracy.

Design/methodology/approach

The development of the model in the study is divided into seven stages: (1) data collection, (2) pre-processing data, (3) selected pre-trained SentenceTransformers model, (4) semantic similarity (sentence pair), (5) keyword similarity, (6) calculate final score and (7) evaluating model.

Findings

The multilingual paraphrase-multilingual-MiniLM-L12-v2 and distilbert-base-multilingual-cased-v1 models got the highest scores from comparisons of 11 pre-trained multilingual models of SentenceTransformers with Indonesian data (Dhini and Girsang, 2023). Both multilingual models were adopted in this study. A combination of two parameters is obtained by comparing the response of the keyword extraction responses with the rubric keywords. Based on the experimental results, proposing a combination can increase the evaluation results by 0.2.

Originality/value

This study uses discussion forum data from the general biology course in online learning at the open university for the 2020.2 and 2021.2 semesters. Forum discussion ratings are still manual. In this survey, the authors created a model that automatically calculates the value of discussion forums, which are essays based on the lecturer's answers moreover rubrics.

Abstract

Purpose

This study aims to identify European positioning on the use of remote customer onboarding solutions in combating financial crime.

Design/methodology/approach

This study is a desktop research that examines European Banking Authority (EBA) policy statements relating to the use of innovative solutions in combating financial crime.

Findings

Technological advancements in biometric data and software tools provide a unique opportunity to address potential paper customer onboarding process deficiencies. Electronic remote customer onboarding solutions equip credit, financial institutions and investment firms with an alternative FTE cost-saving solution, in their pursuit of revenue generation. Whilst the EBA and Financial Action Task Force have provided approval for the utilisation of innovative solutions and AML technologies in combatting financial crime. Hesitancy remains on the ability of credit and financial institutions to use technological solutions as a “magic solution” in preventing the materialisation of money laundering/terrorist financing related risks. Analysis of policy suggests a gravitation towards the increased use of the aforementioned technologies in the interim.

Originality/value

Capitalisation of European banking authority.

Abstract

Background: Geostatistics focuses on spatial or spatiotemporal datasets. Geostatistics was initially developed to generate probability distribution predictions of ore grade in the mining industry; however, it has been successfully applied in diverse scientific disciplines. This technique includes univariate, multivariate, and simulations. Kriging geostatistical methods, simple, ordinary, and universal Kriging, are not multivariate models in the usual statistical function. Notwithstanding, simple, ordinary, and universal kriging techniques utilize random function models that include unlimited random variables while modeling one attribute. The coKriging technique is a multivariate estimation method that simultaneously models two or more attributes defined with the same domains as coregionalization.

Objective: This study investigates the impact of populations on traffic volumes as a variable. The additional variable determines the strength or accuracy obtained when data integration is adopted. In addition, this is to help improve the estimation of annual average daily traffic (AADT).

Methods procedures, process: The investigation adopts the coKriging technique with AADT data from 2009 to 2016 from Montana, Minnesota, and Washington as primary attributes and population as a controlling factor (second variable). CK is implemented for this study after reviewing the literature and work completed by comparing it with other geostatistical methods.

Results, observations, and conclusions: The Investigation employed two variables. The data integration methods employed in CK yield more reliable models because their strength is drawn from multiple variables. The cross-validation results of the model types explored with the CK technique successfully evaluate the interpolation technique's performance and help select optimal models for each state. The results from Montana and Minnesota models accurately represent the states' traffic and population density. The Washington model had a few exceptions. However, the secondary attribute helped yield an accurate interpretation. Consequently, the impact of tourism, shopping, recreation centers, and possible transiting patterns throughout the state is worth exploring.

Abstract

Purpose

The aim of this study was to compare the defined indicators of tuberculosis (TB) control program in the intervention and control prisons, after implementation of the national clinical protocol for TB and HIV management in Iranian prisons, suggesting active health service provision in all steps of service provision.

Design/methodology/approach

This was quasi-experimental study conducted among inmates of two prisons in Iran. Great Tehran prison was purposively chosen as the intervention prison and Karaj prison was purposively chosen as control prison as well. Intervention and control prisons were compared in terms of the TB indicators within three periods (before intervention, during implementation and follow-up period) from October 2013 to June 2014.

Findings

Number of inmates with TB symptoms who underwent TB workup was four times more in intervention prison compared to control prison (9.3 vs 2.5 cases out of 1,000 inmates per month in the case prison compared to the control prison). Such difference was also significant in the intervention prison, comparing before and during the intervention period. The patient finding in case prison increased significantly after the intervention (223.6 vs 81.8 cases out of 100,000 inmates per year). The number of TB cases who received HIV testing increased from 50 to 100%.

Originality/value

Active health service provision has significantly improved indicators in the intervention prison. The authors recommend implementation of this guideline in all prisons of Iran. Integration of other diseases with high burden among prisoners is also recommended in the active health services provision.

Abstract

Purpose

The purpose of this study is to develop and test the causal relationships between alcohol consumption, social support, illness perception, fatigue and functional status among persons with liver cirrhosis. The hypothesized model was developed based on the theory of unpleasant symptoms.

Design/methodology/approach

A cross-sectional study was conducted among 400 persons with liver cirrhosis by stratified random sampling. Data were collected at outpatient departments from four public hospitals across three regions in Thailand. Six self-report questionnaires were utilized to collect data from March to August 2020. The developed model was verified via a structural equation modeling analysis.

Findings

The proposed model fit with the empirical data considering from χ2/df = 2.397 (p = 0.061), root mean square error of approximation (RMSEA) = 0.056, comparative fit index (CFI) = 0.985, Tucker–Lewis index (TLI) = 0.981, and standardized root mean square residual (SRMR) = 0.048. The model explained 71.30% of the total variance in functional status. Social support was the most influential factor affecting functional status both directly and indirectly through illness perception. Illness perception had a negative direct effect on functional status and a positive indirect effect on functional status through fatigue. Fatigue had a negative direct effect on functional status. Alcohol consumption was found as the lowest influential factor affecting functional status.

Originality/value

This is the first study that explores the characteristics of functional status among persons with liver cirrhosis comprehensively. A causal relationship among various variables found in this study would shed light as important fundamental data for developing interventions to enhance functional status among this population.
