Purpose This research describes and evaluates the co-creation of a programme called “A Healthy Choice”. Underpinned by design thinking (DT), this study aims to improve healthfulness food choices in supermarkets among consumers promote their well-being. Design/methodology/approach The features two studies. Study 1 included five co-design workshops with staff ( n = 32) develop consumer-centred programme. findings supported implementation evaluated 2 (an ecological trial). modified supermarket...

This research proposes a new non-parametric approach to pairs trading based on renko and kagi constructions which originated from Japanese charting indicators were introduced academic studies by Pastukhov. The method exploits statistical information about the variability of tradable process. does not find long-run mean process trade towards it like other methods trading. only assumption we need is that properties spread volatility remain reasonably constant. theoretical profitability has...

Increasing demand for hospital services has resulted in more arrivals to emergency department (ED), increased admissions, and, quite often, access block and ED congestion, along with patients' dissatisfaction. Cost constraints limit an increase the number of beds, so alternative solutions need be explored.To propose test different discharge strategies, which, potentially, could reduce occupancy rates hospital, thereby improving patient flow minimising frequency duration congestion...

Pairs trading is a market neutral investment strategy that attracts attention of academics and practitioners. Despite that, very little testing on the real data has been published. This research considers three most cited methods pairs trading, two them had never tested data. Clear rules have defined for all their performance empirically assessed using daily covering 12 years history Australian stock exchange.

Significance of the research paper Time is one resources shoppers bring to a store (along with money). Enabling complete their grocery shopping more efficiently, that spend less time buy desired number items, could result in higher shopper satisfaction and continued patronage. This proposes novel way measuring efficiency by distinguishing “fixed” vs “per item” times for trip. We then analyse differences across different sub-groups offering insights into heterogeneity benchmarks. Research...

When purchasing packaged products within a supermarket, consumers choose between proprietary or private label brands. However, when fresh fruits and vegetables, non-branded produce is the dominant option—with brands only recently becoming available. Previous fast-moving consumer goods (FMCG) research finds that affect loyalty—however, no exists for categories. This first to determine effect of emerging in categories on buying behavior. Our examines consumers’ loyalty toward proprietary,...

In this study, we define a hospital congestion episode as situation where the number of new patients needing admission is greater than available beds in hospital, and investigate likelihood that current day's midnight occupancy will exceed any specified threshold level. We demonstrate measure risk exhibits characteristic sensitivity phenomenon have named hospital's instability wedge. particular, it seen frequently even small changes numbers admitted or discharged can dramatically change...

Traditionally, arbitrage refers to simultaneously buying and selling the same financial assets by taking advantage of a price difference in two or more markets. However, strict sense is hardly obtained after consideration issues concerning transaction costs time value money. By using identical such as Chinese ADRs their underlying securities traded different markets Hong Kong HK dollar New York US constructing very simple trading strategy, this study demonstrates that profits are still...

Combat mission studies are critical for developing an understanding of combat behaviour as part informed decision-making.Combat simulators commonly used this purpose, with the goal complex relationships, such evaluating competing options, force design and operational requirements.As simulation process, a collection event series is recorded to capture progression over time provide insight into causal relationships space.In work we modelled using Markov chains, unfolding pattern events within...

Hospitals come in different sizes and operate under conditions.The problem confronting healthcare planners for a long time has been: How does hospital efficiency relate to its size?Due their complex organisational structures, it would be unrealistic, costly risky hospitals conduct field experiments test the effects of any major change.Mathematical modelling computer simulations offer an effective risk-free approach assess likely impacts proposed change.This study replicates extends "Hospital...

'Avocado lover,' 'banana or 'berry lover' – these words are starting to dominate the contemporary marketing campaigns for fresh fruit and vegetable categories. Such assume that there sizable buyer segments who purchase a particular category more frequently, contributing larger portion of sales, will continue do so into future. Yet, an established body empirical evidence from consumer packaged goods (CPG) categories suggests assumptions could be false. The current study empirically examines...

We discuss several regression-based methods for simulation meta-modelling and illustrate these using combat simulator data.Since the use of common random numbers (CRNs) as a variance reduction technique induces correlations in outputs generated by different inputs, it is crucial to accommodate possibility heterogeneity, heteroskedasticity, correlation when building metamodels.Furthermore, mainstream simulators produces variety output types, including continuous, binary, count data.While...
