Abstract
Purpose
The purpose of this paper is to find the event memory characteristics hidden in trade data.
Design/methodology/approach
First, historical trade data are analyzed to define the events described by multi‐dimensional characteristic variables. The variables containing information are employed to build the event description patterns. Furthermore, a search engine is developed for calendar events, which can search for events in historical data and produce a collection of events. The search engine also extracts relevant system reaction phenomena described by trend distribution for each event pattern. Finally, both event patterns and system reactions construct the episodic memory model.
Findings
The event patterns and the system reactions are used to define the episodic memory model. The search methods for the episodic memory model obtained from trade data set are given.
Research limitations/implications
Accessibility and availability of data are the main limitations affecting where the method can be applied.
Practical implications
The method is helpful for traders when judging the current trade situation from historical memory.
Originality/value
The paper presents a new episodic memory modeling method based on trade data.

Abstract
Purpose
This study aims to use psychological contract theory to explore the substantial impact of illegitimate tasks on the well-being of hospitality employees. It also examines the mediating role of psychological contract breach and the moderating role of employee emotional intelligence within the proposed moderated mediation model.
Design/methodology/approach
Data were collected from 338 hospitality employees in Guangdong, China, and the hypotheses were examined through hierarchical regression analysis.
Findings
The results revealed that illegitimate tasks could negatively impact employee well-being through psychological contract breach. Furthermore, employee emotional intelligence was confirmed as a critical moderator that buffers the negative impact of illegitimate tasks on psychological contract breach.
Originality/value
This research offers novel insights into the dynamics affecting hospitality employee well-being by framing illegitimate tasks within psychological contract theory. It identifies the critical conditions under which employees’ well-being is impacted, thus broadening the understanding of employee–organization interactions.
