Abstract

Purpose

The purpose of this study is to predict the probability and duration of “Buying Intention Survival” (BIS) and to propose a conceptual framework illustrating its determinants. More specifically, it aims to determine the likelihood of buying intention abandonment (BIA) and the time frame in which the intention abandonment might occur.

Design/methodology/approach

The data for this study were collected using an online survey of a sample of 573 Tunisian consumers. The data were then subjected to a survival analysis. This method is used for the first time in this context.

Findings

Results show that the average duration of the BIS could extend over 162 months. Findings also suggest that involvement, anticipated regret linked to a no-purchase decision and social influence have a positive effect on BIS, whereas anticipated regret linked to purchase influences BIS negatively.

Practical implications

Accurately anticipating the date of BIA is of paramount importance for marketers as it allows them to implement strategies that reduce the risk of abandonment and encourage customers to promptly fulfill their purchasing intentions.

Originality/value

This paper introduces a new concept, namely, BIS, and applies a survival analysis method to determine whether purchase intention disappears over time, how soon it may disappear, and possible reasons this may occur.

Abstract

Purpose

Chatbots emerge as a prominent trend within the context of evolving communication settings and enhancing customer experience to improve firms' total quality management strategies. Specifically, users’ initial trust in such chatbots is critical for their adoption. Under the realm of technology acceptance theories, the present research aims to investigate drivers (perceived ease of use, performance expectancy, compatibility, social influence and technology anxiety) and impacts (customer experience and chatbot usage intention) of chatbot initial trust, among Generation Z considered as the more tech-savvy generation, in the particular telecommunication services context.

Design/methodology/approach

Research data were collected using an online questionnaire-based survey to test research hypotheses. A sample of 385 students was selected in Tunisia using a convenience sampling technique. Data were then analyzed through structural equation modeling by AMOS 23.

Findings

The results highlighted that, except for perceived ease of use and performance expectancy, all determinants have a significant influence on chatbot initial trust (positive impact of social influence and compatibility and negative impact of technology anxiety). Furthermore, chatbot initial trust positively stimulates customer experience with chatbots and chatbot intention of use.

Practical implications

Our results provide particular insights to chatbot developers seeking to enhance trust-building features in these systems and telecommunication operators to better understand user adoption and improve chatbot-based customer interactions among Generation Z in emergent markets.

Originality/value

This paper attempts to consolidate and enrich the existing body of chatbot initial trust literature by emphasizing the role of customer experience with chatbots and technology anxiety, as two pivotal consumer-related factors that have not yet been treated together in one research.

Abstract

Purpose

The purpose of this paper is to explore how ISO 26000 inter-marries with millennium development goals (MDGs) with a view to demonstrate and recommend how businesses can successfully use this intermarriage to solve society problems.

Design/methodology/approach

Case methodology was used to investigate how a company can use the social responsibility standard, ISO 26000, to guide its corporate social responsibility (CSR) aimed at contributing to MDGs. The paper focussed on the CSR dimension of community involvement and development (CI&D) interventions in health-related MDGs (4, 5 and 6). Data collection was by semi-structured interviews with CSR managers of the studied company, plus non-participant observation of CSR activities and projects. In order to develop a framework within which the collected data could be analyzed, the authors employed pattern-matching, explanation building and time series analysis. For generalization purposes of findings, the authors were guided by the “adaptive theory approach.”

Findings

The intermarriage is much revealed in health and wellness. This intermarriage also reveals cross-cutting issues which support universal access to health care and prevent illnesses. Lastly, the intermarriage is symbiotic in nature, that is, MDGs contribute what to achieve while ISO 26000 contributes how to achieve.

Research limitations/implications

The case study (Uganda Baati Ltd, - UBL) that informed this research is a subsidiary company of a multinational, SAFAL Group. This provided an indication that global or trans-national forces drive CSR/CI&D at UBL. Thus, the findings may not fit directly with a company that has a local/national focus of its CSR/CI&D.

Practical implications

The paper presents guidelines to use and localize this intermarriage so as to focus CSR on global socio-economic development priorities, identify strategic stakeholders, and pathways to solutions for complex CI&D issues.

Originality/value

This research advances the Post-2015 MDG Development Agenda suggested during the United Nations MDG Summit in 2010 which called for academic contributions on how MDGs can be realized even after 2015.

Abstract

Purpose

Lactobacillus rhamnosus GG, a probiotic of human origin, known to have health beneficial effects can be exposed to osmotic stress when applied in food production as important quantities of sugars are added to the food product. The aim of this study is to assess the mode of action of non‐electrolytes stress on its viability.

Design/methodology/approach

Investigations were carried out on stationary phase cells treated with 0‐1.5M sugars, by means of flow cytometric method (FCM) and plate enumeration method. Osmotically induced changes of microbial carboxyfluorescein (cF)‐accumulation capacity and propidium iodide‐exclusion were monitored. The ability of the cells to extrude intracellularly accumulated cF upon glucose energization was ascertained as an additional vitality marker, in which the kinetics of dye extrusion were taken into consideration as well. Sugar analysis by HPLC was also carried out.

Findings

The results of FCM analysis revealed that with sucrose, only cells treated at 1.5M experienced membrane perturbation but there was a preservation of membrane integrity and enzymatic activity. There was no loss of viability as shown by plate counts. In contrast, the majority of trehalose‐treated cells had low extent of cF‐accumulation. For these samples a slight loss of viability was recorded on plating (logN/No ∼ −0.45). At 0.6M, cells had similar extrusion ability as the control cells upon glucose energization. However, 20 per cent of sucrose‐treated cells and 80 per cent of trehalose‐treated cells extruded the dye in the first 10min.

Originality/value

This finding pointed out the importance of trehalose to enhance the dye extrusion activity, which is regarded as an analogue of the capability of cells to extrude toxic compounds. Sugars exert different effects on the physiological and metabolic status of LGG but none caused a significant viability loss. LGG can be a choice probiotic bacterium in sugar‐rich food production e.g. candies, marmalade etc., in which exposure to high osmotic pressure is be expected.

Abstract

Purpose

This is the first part of a two-part paper. The purpose of this paper is to report on methods that use the Response Surface Methodology (RSM) to investigate an Evolutionary Algorithm (EA) and memory-based approach referred to as McBAR – the Mapping of Task IDs for Centroid-Based Adaptation with Random Immigrants. Some of the methods are useful for investigating the performance (solution-search abilities) of techniques (comprised of McBAR and other selected EA-based techniques) for solving some multi-objective dynamic resource-constrained project scheduling problems with time-varying number of tasks.

Design/methodology/approach

The RSM is applied to: determine some EA parameters of the techniques, develop models of the performance of each technique, legitimize some algorithmic components of McBAR, manifest the relative performance of McBAR over the other techniques and determine the resiliency of McBAR against changes in the environment.

Findings

The results of applying the methods are explored in the second part of this work.

Originality/value

The models are composite and characterize an EA memory-based technique. Further, the resiliency of techniques is determined by applying Lagrange optimization that involves the models.

Abstract

Purpose

This paper aims to examine the relationship between workplace incivility and the intention to self-initiate expatriation and whether this relationship is mediated by affective organizational commitment. It also explores the moderating role of career commitment in this proposed model.

Design/methodology/approach

The data were collected using a questionnaire among 145 young physicians from Tunisian hospitals. Hypotheses are tested using the PROCESS macro (models 4 and 7) in SPSS.

Findings

Workplace incivility is negatively related to affective organizational commitment, which in turn is related to the intention to self-initiate expatriation. Furthermore, career commitment moderates the indirect effect of workplace incivility on expatriate intention through affective organizational commitment. Specifically, when career commitment is high, the indirect effect on the intention to self-initiate expatriation is stronger.

Originality/value

This is one of the first studies to examine the indirect influence of workplace incivility on the intention to self-initiate expatriation. Moreover, it furthers our understanding of a contingent factor that influences this indirect effect.

Abstract

Purpose

This paper aims to evaluate hematological parameters, blood glutathione (GSH), serum glucose-6-phosphate dehydrogenase (G6-PD) and liver function in favism animals' models after oral intake with a mixture of pickled olives and Vicia faba (V. faba) seeds.

Design/methodology/approach

Favism is a life-threatening hemolytic crisis. It results from the ingestion of V. faba by the individuals. The hemoglobin (Hb), hematocrit (Hct), red blood cells (RBCs), white blood cells (WBCs), serum glucose, blood GSH, serum G6-PD, serum thiobarbaturic acid reactive substances (TBARS), liver protein and liver function were evaluated after oral administration with a mixture of pickled olives with V. faba seeds in favism animals' models.

Findings

The favism-, vicine- and convicine-treated animals showed a significant decrease (p < 0.01) in Hb (6.42, 7.23 and 5.96 g/dl), Hct (25.4, 26.4 and 25.1%), RBCs (2.56, 2.45 and 2.60 106 cells/mm3, WBCs (4.35, 4.25 and 4.30 103 cells/mm3), serum glucose (95.8, 97.1 and 96.5 mg/dl), blood GSH (24.7, 26.6 and 23.8 mg/dl), serum G6-PD (15.8, 15.9 and 15.7 U/L), serum aspartate aminotransferase (6.35, 6.59 and 5.97 U/L), alanine aminotransferase (4.49, 4.61 and 4.50 U/L), total protein (6.54, 6.59 and 6.40 g/dl), albumin (3.84, 3.91 and 3.75 g/dl), globulin (2.70, 2.48 and 2.65 g/dl) and liver protein (3.37, 3.10 and 3.42 g/g tissue) but a significant increase (p < 0.01) in serum TBARS (38.7, 38.9 and 39.4 nmol/dl), alkaline phosphatase (275, 271 and 281 U/L) and total bilirubin (0.93, 0.89 and 0.91 mg/dl) compared to Hb (16.3 g/dl), Hct (45.3%), RBCs (5.80 106 cells/mm3), WBCs (9.45 103 cells/mm3), serum glucose (96.5 mg/dl), blood GSH (39.7 mg/dl), serum G6-PD (36.1 U/L), serum TBARS (18.0 nmol/dl), serum aspartate aminotransferase (19.8 U/L), alanine aminotransferase (9.23 U/L), alkaline phosphatase (214 U/L), total bilirubin (0.57 mg/dl), total protein (8.76 g/dl), albumin (4.85 g/dl), globulin (3.91 g/dl) and liver protein (6.28 g/g tissue) in control group. The oral administration with pickled olives + V. faba, pickled olives + vicine and pickled olives + convicine into favism animals' models, vicine-treated animals and convicine-treated animals, respectively pushed all the above-mentioned parameters to near the control levels.

Originality/value

V. faba contains vicine and convicine glycosides. Vicine and convicine glycosides in V. faba are hydrolyzed by intestinal microflora to aglycones divicine and isouramil, respectively. Divicine and isouramil are highly reactive compounds generating free radicals where divicine and isouramil are the main factors of favism. The ß-glucosidase in pickled olives converts both vicine and convicine glycosides into aglycones divicine and isouramil, respectively, in aerobic condition outside the human body (in inactive forms) and prevent these glycosides to cause favism.
