The purpose of this paper is to find the event memory characteristics hidden in trade data.

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.

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.

Accessibility and availability of data are the main limitations affecting where the method can be applied.

The method is helpful for traders when judging the current trade situation from historical memory.

The paper presents a new episodic memory modeling method based on trade data.

Reliability of RAM memory systems is impaired by environmental disturbances, causing soft errors, whereby one data bit is transformed to another bit. Single‐error correcting codes with memory scrubbing offer the most effective method to recover from such errors. This paper analyzes the reliability and determines the MTTF for simplex and duplex memory systems with single‐error correction and/or soft‐error scrubbing recovery. It extends previous work on the deterministic scrubbing recovery of simplex memory systems by using a more general model that takes into account cancelling soft errors. In the duplex memory system an additional level of static redundancy is proposed by employing a decoding algorithm at the memory module level. The reliability analysis of the duplex system with soft‐error scrubbing takes into account the decoder output which upon scrubbing transforms words with a number of multiple errors to words with a different number of errors. Computer results show that this combination of data and system redundancy provides more reliability than either data or system redundancy alone.

This paper aims to develop a novel grey Bernoulli model with memory characteristics, which is designed to dynamically choose the optimal memory kernel function and the length of memory dependence period, ultimately enhancing the model's predictive accuracy.

This paper enhances the traditional grey Bernoulli model by introducing memory-dependent derivatives, resulting in a novel memory-dependent derivative grey model. Additionally, fractional-order accumulation is employed for preprocessing the original data. The length of the memory dependence period for memory-dependent derivatives is determined through grey correlation analysis. Furthermore, the whale optimization algorithm is utilized to optimize the cumulative order, power index and memory kernel function index of the model, enabling adaptability to diverse scenarios.

The selection of appropriate memory kernel functions and memory dependency lengths will improve model prediction performance. The model can adaptively select the memory kernel function and memory dependence length, and the performance of the model is better than other comparison models.

The model presented in this article has some limitations. The grey model is itself suitable for small sample data, and memory-dependent derivatives mainly consider the memory effect on a fixed length. Therefore, this model is mainly applicable to data prediction with short-term memory effect and has certain limitations on time series of long-term memory.

In practical systems, memory effects typically exhibit a decaying pattern, which is effectively characterized by the memory kernel function. The model in this study skillfully determines the appropriate kernel functions and memory dependency lengths to capture these memory effects, enhancing its alignment with real-world scenarios.

Based on the memory-dependent derivative method, a memory-dependent derivative grey Bernoulli model that more accurately reflects the actual memory effect is constructed and applied to power generation forecasting in China, South Korea and India.

This study aims to explain the evaluation of a training programme for older adults to make them facilitators of a memory training project. Older adults were trained as facilitators to respond to the need to continue training memory and promote the active role of adults in the community.

The Kirkpatrick model was used to comprehensively evaluate the training programme. The participants were 89 older adults from the city of Barcelona, with an average age of 73.1 years old. To evaluate the training programme, six instruments were administered, adapted to the four levels established in Kirkpatrick’s model.

The results obtained show that the programme to train facilitators enables older adults to become facilitators in a memory training project.

Two limitations have been identified. The first is to analyse the extent to which the participants learned from the facilitator’s memory training project. The second is the methodological improvement for future research on two issues: strengthening the validity of the instruments and incorporating a control group.

The implications for practice, presented in this article, are twofold. One is the importance of lifelong learning as a resource for remaining healthy. Another implication is the active role of older adults in the community.

This research enables older adults to become involved in responding to their own needs such as memory training. In turn, it contributes to promoting active ageing and community participation.

The purpose of this study is to clarify the role of various levels of modality richness [text-visual, audiovisual and augmented reality interactive technology (ARIT)] on vivid memories (visual sensory detailed, emotionally intense, first-person perspective and coherent) and exploratory behavior. To clarify which modality richness online retailers use is more appropriate to create a virtual reality simulation experience to fill a significant gap in the sensory interactive marketing paradigm.

A task-based laboratory study was conducted to provide users with private try-on space. A total of 429 valid questionnaires were collected, and partial least squares path modeling was adopted to test hypotheses.

The results indicate that various levels of modality richness (text-visual, audiovisual and ARIT) positively affect vivid memories (visual sensory detailed, emotionally intense, first-person perspective and coherent), and vivid memories successfully induce exploratory behavior.

The study results could also help retailers and brands with clear guidance in designing and creating simulation experience services and choosing the best way to present products. With the results of this research, retailers will also be able to grasp better the critical points of introducing innovative technology into the service experience and then create the benefits of digital economic growth.

Exploring which digital interactive technology online retailers use is more appropriate to create a virtual reality shopping experience to fill a significant gap in the sensory interactive marketing paradigm. Exploring the antecedents of vivid memories in a digital sensory interactive experience contributes to the body schema literature and the script theory. We draw from construal level theory (CLT) to clarify the impact of various levels of modality richness on driving the difference in sensory simulation schema to break through the limited findings of previous studies, namely using CLT to interpret psychological distance.

This article explores memory work and storytelling as an organising tool through family histories, offering theoretical and methodological implications and extending existing conceptualisations of memory work as a feminist method. This approach is termed as impressionist memory work.

To illustrate impressionistic memory work in action, the article presents two family histories set during Second World War and invite the reader to engage in the “undoing” of these stories and dominant ways of knowing through storytelling. This method challenges the taken-for-granted roles, plots and detail of family histories to uncover the obscured or silenced stories within, together with feminine, affective and embodied subjectivities, marginalisation and social inequalities.

This study argues that impressionistic memory work as a feminist method can challenge the silencing and gendering of experiences in co-constructed and co-interpreted narratives (both formal and informal ones).

This study shows that engagement with impressionistic memory work can challenge taken-for-granted stories with prominent male actors and masculine narratives to reveal the female actors and feminine narratives within. This approach will offer a more inclusive perspective on family histories and deeper engagement with the marginalised or neglected actors and aspects of our histories.

The purpose of this study was to investigate cognitive behavior therapists and trainees’s beliefs about various aspects of traumatic memory and to investigate cognitive behavior therapists’ practices in relation to alleged traumatic experiences and whether they are linked with their beliefs about various aspects of traumatic memory.

In the current study, the authors surveyed, by a questionnaire (in Italian), certified Italian cognitive behavioral (CB) therapists and trainees with respect to their beliefs in traumatic memories and whether they discussed about the possibility of repressed memory with their patients.

The majority of participants held strong beliefs about many controversial aspects related to traumatic memory, such as the mind being able to block out of consciousness memories of traumatic experiences. Also, more than half of CB therapists stated that they sometimes discussed about the importance of traumatic events in the genesis of their patient’s disorder and half of them sometimes talked with patients about memories for traumatic events of which they may be unaware. Such practices could lead to false memories of abuse

One particularly novel finding relates to the evidence that therapists reported that they had discussed with patients the importance of traumatic events in the genesis of their illness and frequently noted that they talked about the possibility of repressed memories with them. In turn, patients may be induced to recall traumatic experiences from their lives, thereby producing false memories which may tear families apart and could even lead to wrongful convictions.

To explore the value in reminiscing about past festivals as a potential way of improving wellbeing in socially isolated times.

The paper uses previous research on reminiscence, nostalgia and wellbeing to underpin the analysis of self-recorded memory narratives. These were gathered from 13 pairs of festivalgoers during Covid-19 restrictions and included gathering their individual memories and their reminiscences together. The participant pairs were a mix of friends, family and couples who had visited festivals in the UK, Finland and Denmark.

Four key areas that emerged through the analysis were the emotions of nostalgia and anticipation, and the processes of reliving emotions and bonding through memories.

Future studies could take a longitudinal approach to see how memory sharing evolves and the impact of this on wellbeing. The authors also recommend undertaking similar studies in other cultural settings.

This study findings have implications for both post-festival marketing and for the further development of reminiscence therapy interventions.

The method provides a window into memory sharing that has been little used in previous studies. The narratives confirm the value in sharing memories and the positive impact this has on wellbeing. They also illustrate that this happens through positive forms of nostalgia that centre on gratitude and lead to hope and optimism. Anticipation, not emphasised in other studies, was also found to be important in wellbeing and was triggered through looking back at happier times.

This paper’s main aim is to check the mediating effect of supply chain memory in the relationship between using digital technologies and both supply chain resilience and robustness. In addition, the impact of the COVID-19 disruption was tested as a moderator of the impact of supply chain memory on supply chain resilience and robustness.

Altogether, 257 supply chain managers answered the questionnaire, and data were analysed through structural equation modelling.

This paper contributes to theory and practice by demonstrating that the experience, familiarity and knowledge to deal with disruptions partially mediate the relationship between digital technologies, resilience and robustness. Moreover, our results show that memory is less efficient for the supply chain to maintain an acceptable level of performance in case of a new extreme disruptive event like COVID-19. The full model was able to explain 36.90% of supply chain memory, 41.58% of supply chain resilience and 46.21% of supply chain robustness.

The study helps to understand how to develop supply chain memory, positioning digital technologies as an antecedent of it. The impact of supply chain memory on supply chain resilience and robustness is proved. Knowledge about the impact of industry 4.0 technologies on disruption management is quantitatively improved. It demonstrates that digital technologies impact resilience and robustness mainly through supply chain memory. The study proves that supply chain memory is less efficient for the chain remains effective when a non-routine disruptive event occurs, but it is still imperative to recover from it.
