Abstract
Purpose
The purpose of this paper is to examine the efficacy of microbial elimination using different sanitizers in raw vegetables (cherry tomatoes, spring onions, Chinese chives, and chicory) and to analyze the efficacy of Escherichia coli O157:H7 reduction by type of sanitizer and vegetable.
Design/methodology/approach
To assess the sanitizing effects of microbial elimination by variety of vegetable, the samples were grouped into four different washing methods: control (no sanitizer), 100 ppm chlorine, 100 ppm electrolyzed water, and 200 ppm electrolyzed water after prewashing. Subsequently, quantitative microbiological experiments were conducted to assess aerobic mesophilic plate count (APC), coliform, E. coli, and Bacillus cereus, and sensory changes of the sanitized vegetables were tested. Thereafter, measurement of the sanitizing effects on bacterial reduction after inoculation with E. coli O157:H7 was conducted.
Findings
The microbial levels of four types of vegetables ranged from 3.37 to 5.24 log CFU/g for APC, 2.41 to 5.57 log CFU/g for E. coli, 0.25 to 5.40 log CFU/g for coliform, and 0.83 to 5.44 log CFU/g for B. cereus. After three types of sanitizing treatments, microbial reduction effects showed 0.94-1.84 log CFU/g for APC, 0.56-1.00 log CFU/g for E. coli, 0.18-1.26 log CFU/g for coliform, and 0.56-1.23 log CFU/g for B. cereus (p<0.05). In sensory evaluation, there were no significant differences in taste and flavor between with and without sanitizing treatments. Regarding bacterial reduction after inoculation with E. coli O157:H7, the microbial reduction on vegetables was shown to be in the range of 0.27-1.57 log CFU/g with 100 ppm sodium hypochlorite, 0.66-3.07 log CFU/g with 100 ppm electrolyzed water, and 0.79-2.55 log CFU/g with 200 ppm electrolyzed water. Chicory, cherry tomato, and spring onion showed significant reduction levels of E. coli O157:H7 after sanitation (p<0.05).
Originality/value
This study revealed that different sanitization methods are required for different types of vegetables. Electrolyzed water treatment (100 ppm) is a more effective and safe method of washing raw vegetables. Given that the main purpose of sanitizing fresh-cut produce is to maximally reduce microorganism levels, different methods of sanitizing fresh-cut produce with an adequate washing method should be used according to vegetable type.

Abstract
Purpose
The purpose of this paper is to contribute to a better, empirically grounded and theoretically informed understanding of data analytics (DA) use and nonuse in accounting for decision-making. To that end, it explores the links between accounting logic, commercial logic and DA use in financial due diligence (FDD).
Design/methodology/approach
The paper reports the findings of a case study of DA use in the FDD practice of a Big Four accounting firm in Sweden (Pseudonym: DealCo). The primary data comprises semistructured interviews, observations and additional meetings. Institutional logics is mobilized as method theory.
Findings
First, accounting logic and commercial logic both drove and hindered DA use in DealCo’s FDD practice in different ways. Second, conflicting prescriptions for DA use existed mostly within commercial logic rather than between accounting logic and commercial logic. Third, accounting logic and commercial logic, as perceptual and conceptual filters, seemed to shape DealCo’s advisors’ understanding of DA and give rise to an efficiency-centric DA logic. This logic, in turn, as a high-level model of how to use DA in the context of FDD, governed DA use broadly.
Originality/value
The paper draws attention to direct and indirect links between accounting logic and commercial logic, on the one hand, and DA conceptions and use, on the other hand. It, thereby, advances prior theorization of DA use in accounting for decision-making.

Abstract
Purpose
The purpose of this paper is to appraise methodological rigor in the application of discriminant analysis (DA) in export-focused research and to offer guidelines for future studies.
Design/methodology/approach
The sample includes 89 empirical peer-reviewed studies, comprising 102 models published over the period 1979-2014. Content analysis and vote counting are used to evaluate each of these studies.
Findings
This review highlights major flaws in the application of DA in export research. The shortcomings are self-evident particularly concerning suitability of DA for research context, completeness in the reporting of descriptive results, and validity and reliability of predictive results.
Practical implications
The study takes the position that the lack of methodological rigor may be undermining the eminence of knowledge in exporting, and this has extensive implications for both researchers and practitioners.
Originality/value
This review outlines steps to assess methodological rigor associated with DA and offers guidelines for scholars seeking to enhance rigor in future research.

Abstract
Purpose
This paper aims to investigate the efficiency and effectiveness of alternative credit‐scoring models for consumer loans in the banking sector. In particular, the focus is upon the financial risks associated with both the efficiency of alternative models in terms of correct classification rates, and their effectiveness in terms of misclassification costs (MCs).
Design/methodology/approach
A data set of 630 loan applicants was provided by an Egyptian private bank. A two‐thirds training sample was selected for building the proposed models, leaving a one‐third testing sample to evaluate the predictive ability of the models. In this paper, an investigation is conducted into both neural nets (NNs), such as probabilistic and multi‐layer feed‐forward neural nets, and conventional techniques, such as the weight of evidence measure, discriminant analysis and logistic regression.
Findings
The results revealed that a best net search, which selected a multi‐layer feed‐forward net with five nodes, generated both the most efficient classification rate and the most effective MC. In general, NNs gave better average correct classification rates and lower MCs than traditional techniques.
Practical implications
By reducing the financial risks associated with loan defaults, banks can achieve a more effective management of such a crucial component of their operations, namely, the provision of consumer loans.
Originality/value
The use of NNs and conventional techniques in evaluating consumer loans within the Egyptian private banking sector utilizes rigorous techniques in an environment which merits investigation.

Abstract
Purpose
The purpose of this paper is to examine whether Malaysian HR professionals emotions regulation strategy mediates the relationship between their personality and burnout. To date few studies have examined such issues, especially among emerging Asian economies such as Malaysia.
Design/methodology/approach
A model linking the Big Five personality to emotions regulation (deep and surface acting (SA)) and burnout was tested using data from 136 employees from a large Malaysian financial institution.
Findings
Results indicate that the Big Five had different effects on burnout and emotion regulation. Only SA mediated the relationship between extroversion, emotional stability and openness on personal-related burnout and between extroversion and openness on work-related burnout.
Originality/value
The study represents one of the first attempts in the literature to explore how individual differences and emotions influence burnout among HR professionals. The study also addresses calls in the literature to further explore the role of emotions in the workplace in non-Western contexts.

Abstract
Human performance, particularly that of the warfighter, has been the subject of a large amount of research during the past few decades. For example, in the Medline database of medical and psychological research, 1,061 papers had been published on the topic of “military performance” as of October 2003. Because warfighters are often pushed to physiological and mental extremes, a study of their performance provides a unique glimpse of the interplay of a wide variety of intrinsic and extrinsic factors on the functioning of the human brain and body. Unfortunately, it has proven very difficult to build performance models that can adequately incorporate the myriad of physiological, medical, social, and cognitive factors that influence behavior in extreme conditions. The chief purpose of this chapter is to provide a neurobiological (neurochemical) framework for building and integrating warfighter performance models in the physiological, medical, social, and cognitive areas. This framework should be relevant to all other professionals who routinely operate in extreme environments. The secondary purpose of this chapter is to recommend various performance metrics that can be linked to specific neurochemical states and can accordingly strengthen and extend the scope of the neurochemical model.

Abstract
Purpose
Drawing on cultural intelligence and social exchange theories, this study examines cultural intelligence and its effects on proactive service performance and the mediating role of leader's collaborative nature and the moderating role of cultural training and emotional labor, particularly deep acting and surface acting, in the relationship between cultural intelligence and proactive service performance.
Design/methodology/approach
The study sample comprised 510 healthcare practitioners. Structural equation modeling was used to examine the hypotheses.
Findings
The results show that cultural intelligence positively influences proactive service performance. Additionally, leadership's collaborative nature influences proactive service performance. The moderating effect of cultural training and deep acting positively influences the relationship between cultural intelligence and proactive service performance. In contrast, surface acting reveals a reverse effect, thus exhibiting a positive effect on this relationship.
Research limitations/implications
These findings suggest that public healthcare organizations should pay more attention in improving deep acting, cultural training and leadership's collaborative nature for optimal service performance.
Originality/value
The novelty of this study lies in its presentation of an integrated framework based on cultural intelligence and social exchange theories that can solve the contemporary challenges facing healthcare firms operating in emerging markets in integrating cultural intelligence and service performance.

Abstract
Purpose
The importance of cybernetic controls (CC) in the context of accounting information systems (AIS) in increasing data accuracy (DA) and improving decision-making (DM) has attracted much attention. In this study, the paper analyses the moderating role of CC on the relationship between DA and DM in AIS, which is supposed to be a case of construction projects in Iraq.
Design/methodology/approach
Data were collected using a questionnaire-structured interview targeted at construction site managers and project managers, employing probability sampling on the 253 valid responses, which was analysed using the partial least squares structural equation modelling (PLS-SEM) method.
Findings
CC significantly reduced the role of the moderating aspect of the DA and positively influenced DM in AIS. These results provided a base for the research postulates, including integrating CC in AIS to offer an overdue solution to challenges in construction project DM.
Practical implications
Empirical outcomes of the study demonstrated that the implementation of CC in AIS can be applied successfully to the accounting of exact data and precision decisions in construction projects. Such lessons are strategically important to practitioners needing optimal AIS performance with a view to industry satisfaction.
Originality/value
The work has a breakthrough quality in the study at hand by stressing that CC moderate the link of DA to the DM approach in AIS. This area lacks exposition when construction projects in Iraq are the case. The findings of the research are aligned with the criteria of good governance in the context of the use of electronic systems to make decisions in AIS.

Abstract
Purpose
The purpose of this paper is to assess impact of destination brand experience (DBE) on destination advocacy (DA) and to assess the role of trust and loyalty as moderators in the relationship.
Design/methodology/approach
Data was collected from a sample of 595 tourists from destinations in India. This study used structural equation modeling and moderated regression analysis to test the hypotheses.
Findings
Results confirm the impact of all four dimensions of DBE (sensory, behavioral, affective and intellectual) on DA. Furthermore, the moderating role of loyalty and trust is established.
Research limitations/implications
The study sample is drawn from only few Indian destinations. India boasts of several different types of destinations (wildlife, adventure, heritage, etc.). Future studies may do a comparative analysis of the influence of DBE dimensions across diverse destination types.
Originality/value
Although past studies have examined the association between DBE and outcomes such as visit intentions, intention to recommend a destination, there is paucity of research that explores the direct association between DBE and DA. The uniqueness of the study lies in associating loyalty and trust as moderators in the relationship of DBE and DA.

Abstract
Purpose
This study develops and tests a comprehensive model that examines whether dimensions of supervisors’ job demands and resources influence their work motivation through their job strain levels while managing disability accommodation (DA).
Design/methodology/approach
The proposed model leverages the assumptions of established job demand and resources theories, including demand-ability fit, job demand-control, job demand-control-support, and effort-reward balance models. Then, we tested with the quantitative data from 335 British, Canadian, American, Australian, Dutch, and German supervisors with recent DA experience.
Findings
This study found support for the proposed model. Job control and social support directly affected work motivation, while job strain did not mediate the relationship between job control and social support and work motivation. The results suggest that employers looking to improve the likelihood of DA success should focus on providing adequate job control, social support, and rewards to supervisors responsible for accommodating employees with disabilities.
Practical implications
This research enhances our understanding of how additional DA responsibilities impact supervisors and aids in the development of effective DA management policies and interventions, providing robust support for practitioners.
Originality/value
This study contributes to extending the DA literature by testing the applicability of different theoretical models to explain the effect of the additional DA responsibility on supervisors’ job demand, strain, and motivation levels and identify the resources to mitigate them.
