Published: December 2021

PurposeForecasting techniques improve supply chain resilience by ensuring that the correct parts are available when required. In addition, accurate forecasts conserve precious resources and money by avoiding new start contracts to produce unforeseen part requests, reducing labor intensive cannibalization actions and ensuring consistent transportation modality streams where changes incur cost. This study explores the effectiveness of the United States Air Force’s current flying hour-based demand forecast by comparing it with a sortie-based demand forecast to predict future spare part needs.Design/methodology/approachThis study employs a correlation analysis to show that demand for reparable parts on certain aircraft has a stronger correlation to the number of sorties flown than the number of flying hours. The effect of using the number of sorties flown instead of flying hours is analyzed by employing sorties in the United States Air Force (USAF)’s current reparable parts forecasting model. A comparative analysis on D200 forecasting error is conducted across F-16 and B-52 fleets.FindingsThis study finds that the USAF could improve its reparable parts forecast, and subsequently part availability, by employing a sortie-based demand rate for particular aircraft such as the F-16. Additionally, our findings indicate that forecasts for reparable parts on aircraft with low sortie count flying profiles, such as the B-52 fleet, perform better modeling demand as a function of flying hours. Thus, evidence is provided that the Air Force should employ multiple forecasting techniques across its possessed, organically supported aircraft fleets. The improvement of the forecast and subsequent decrease in forecast error will be presented in the Results and Discussion section.Research limitations/implicationsThis study is limited by the data-collection environment, which is only reported on an annual basis and is limited to 14 years of historical data. Furthermore, some observations were not included because significant data entry errors resulted in unusable observations.Originality/valueThere are few studies addressing the time measure of USAF reparable component failures. To the best of the authors’ knowledge, there are no studies that analyze spare component demand as a function of sortie numbers and compare the results of forecasts made on a sortie-based demand signal to the current flying hour-based approach to spare parts forecasting. The sortie-based forecast is a novel methodology and is shown to outperform the current flying hour-based method for some aircraft fleets.
GAMES, game theory and artificial intelligence
Authors: Hanley John T. 
Published: December 2021

PurposeThe purpose of this paper is to illustrate how game theoretic solution concepts inform what classes of problems will be amenable to artificial intelligence and machine learning (AI/ML), and how to evolve the interaction between human and artificial intelligence.Design/methodology/approachThe approach addresses the development of operational gaming to support planning and decision making. It then provides a succinct summary of game theory for those designing and using games, with an emphasis on information conditions and solution concepts. It addresses how experimentation demonstrates where human decisions differ from game theoretic solution concepts and how games have been used to develop AI/ML. It concludes by suggesting what classes of problems will be amenable to AI/ML, and which will not. It goes on to propose a method for evolving human/artificial intelligence.FindingsGame theoretic solution concepts inform classes of problems where AI/ML 'solutions' will be suspect. The complexity of the subject requires a campaign of learning.Originality/valueThough games have been essential to the development of AI/ML, practitioners have yet to employ game theory to understand its limitations.

Published: December 2021

PurposeChina's marine economy occupies an important position within the national economy, and its contribution thereto is constantly improving. The overall operation of the marine economy shows positive developmental trends with potential for further growth. The purpose of this research is to analyse the prosperity of China's marine economy, reveal trends therein and forecast the likely turning point in its operation.Design/methodology/approachBased on the periodicity and fluctuation of China's marine economy development, China's marine economic prosperity indicator system is established from five perspectives. On this basis, China's marine economic operation prosperity index can be synthesised and calculated, then a dynamic factor model is constructed. Using the filtering method to calculate China's marine economic operational Stock–Watson index, Markov switching has been used to determine the trend to transition. Furthermore, China's current marine economic prosperity is evaluated through analysis of influencing factors and correlation analysis.FindingsThe analysis shows that, from 2017 to 2019, the operation of the marine economy is relatively stable, and the prosperity index supports this finding; meanwhile it also exposes problems in China's marine economy, such as an unbalanced industrial structure, low marine economic benefits and insufficient capacity for sustainable development.Originality/valueThrough the analysis of the prosperity of China's marine economy, the authors reveal the trends in China's marine economy and forecast its likely future turning point.
Rendering viscose fabric dye-able with anionic dyes using plasma treatment technique and chitosan nanoparticles as an eco-friendly approach
Authors: Mostafa Khaled 
Published: December 2021

Purpose
This paper aims at studying the oxygen plasma treatment and the previously prepared and fully characterized chitosan nanoparticles (CNPs) as a green and eco-friendly strategy for surface modification of viscose fabric. This was done to render viscose fabric dye able with two types of acid dyes that do not have direct affinity to fix on it via improving the fabric wettability.

Design/methodology/approach
To achieve the goal, viscose fabric was activated with oxygen plasma at optimum conditions and coated with different concentrations of CNPs solution via conventional pad dry cure technique. The untreated and plasma-treated fabrics with CNPs were dyed with two types of acid dyes, namely, Acid Orange 7 and Methyl Red under determined conditions. The color strength (K/S), fastness properties to light, rubbing and perspiration, add on %, tensile strength, wettability and durability of the dyed samples were determined and compared.

Findings
The results divulged that oxygen plasma-treated fabric with CNPs and the aforementioned dyes in question could improve the flowing properties in comparison with untreated fabric: (a) the fabric wettability expressed as wetting area mm2; (b) the dye ability and fastness properties of viscose fabrics expressed as K/S and fastness properties; and (c) the strength properties and add on % of the treated fabric. On the other hand, the durability of the plasma-treated fabric decreased with increasing washing cycles.

Originality/value
The novelty addressed here was using plasma treatment as an eco-friendly pre-treatment approach for attachment of CNPs as a multifunctional green bio-nano polymer onto viscose fabric, which improved the dyeing properties of the fabric with acid dyes that do not have direct affinity to fix onto it.
Role of mall attractiveness in shaping fashion shopping orientation of apparel shoppers: a segmentation approach
Authors: Kumar Ajay , Kashyap Anil Kumar 
Published: December 2021

Purpose
The purpose of this study is to identify distinct segments of apparel shoppers based on their fashion shopping orientation. The difference among the segments based on mall attractive dimension is also examined.

Design/methodology/approach
The data were collected through mall intercept survey from the mall shoppers. Samples of 375 respondents are used for data analysis purpose. Exploratory factor analysis is used to extract the factors of fashion shopping orientation and mall attractive dimensions while K-means cluster analysis is applied to identify the segments.

Findings
This study resulted in three factors of fashion orientation of apparel shoppers, i.e. fashion involvement, variety seeking and economic value, and four factors of mall attractive dimensions: convenience, entertainment, atmosphere and architecture design. Based on these factors, this study came out with three distinct segments of fashion shoppers: pragmatic shoppers, variety seeking shoppers and highly fashioned shoppers. These three segments are attracted towards the mall dimension differently.

Originality/value
This paper presents the three distinct profiles of fashion shoppers based on their fashion shopping orientation and mall attractive dimensions. The findings of this study may help retailers and mall developers to target mall visitors appropriately.
Influence of emotions displayed by employees during service recovery
Authors: Sicilia María , Caro-Jiménez M. Carmen , Fernández-Sabiote Estela 
Published: December 2021

Purpose
While research evidences how customers’ emotions can influence their consumer experience, understanding of how employees’ displayed emotions affect the customer service experience is more limited. Drawing on affect transfer theory, the authors test for the mediating role of attitude towards the employee, which is proposed to mediate the effect of employees’ displayed emotion on customers’ satisfaction with recovery. As service recovery entails a critical service experience in which emotions can easily rise, this paper aims to highlight the pivotal role of employee-displayed emotions during service recovery.

Methodology
A scenario-based experiment in the context of an airline service failure recovery (3 × 2 between-subjects design) manipulates frontline employees’ emotions (anger vs happiness vs no specific emotion) and the quality of the solution (bad vs good).

Findings
Employees’ displayed emotions directly affect attitude towards the employee and indirectly affect service recovery satisfaction. Moreover, attitude towards the employee is affected more by the employee’s displayed emotion when the solution offered is bad compared to good.

Practical implications
Employees’ emotions displayed during service recovery can enhance or damage service recovery strategies. Employees should control for negative emotions in the case of service failure, especially when unable to provide a good solution.

Originality
Emotions displayed by employees can influence the customer’s service recovery evaluations. There is an interesting interaction between the quality of the solution and employees’ displayed emotions. Additionally, the mantra of “service with a smile” may not be valid in the case of service recovery: rather, employees should avoid displaying negative emotions.
A systematic literature review of food sustainable supply chain management (FSSCM): building blocks and research trends
Authors: Palazzo Maria , Vollero Agostino 
Published: December 2021

PurposeThe purpose of this paper is to explore the increased research attention gained by sustainability in food supply chain management. Although previous review studies have focused on aspects such as traceability, food safety, and performance measurement, sustainability has rarely been considered as a means of integrating these issues.Design/methodology/approachThe paper presents a comprehensive review of the literature on food sustainable supply chain management (FSSCM). Using systematic review methods, relevant studies published from 1997 to early 2021 are explored to reveal the research landscape and the gaps and trends.FindingsThe paper shows the building blocks and the main research directions in FSSCM, particularly considering the opportunities in “neglected” emerging countries. Insights are provided into the various elements of the sustainability supply chain in the food industry, which have previously been analysed separately.Originality/valueOnly a few researchers have systematically reviewed the literature or taken a bibliometric approach in their analyses to provide an overview of the current trends and links between sustainability and food supply chain management.
Momentary associations between stress and alcohol craving in the naturalistic environment: differential associations for Black and White young adults
Authors: Pedersen Sarah L. , Kennedy Traci M. , Holmes Jordan , Molina Brooke S. G. 
Published: December 2021

AbstractBackground and AimsBlack drinkers compared with White drinkers experience more alcohol‐related problems. Examination of social determinants of inequities in alcohol problems is needed. The current study measured (1) associations between acute stress and alcohol craving in the naturalistic environment for self‐identified Black and White individuals who drink alcohol and (2) whether a history of attention deficit hyperactivity disorder (ADHD) moderated these associations.Design and SettingObservational study using ecological momentary assessment (EMA) to collect data from participants at six semi‐random time‐points throughout the day during a 10‐day period. A series of three‐level multi‐level models examined between‐ and within‐person associations for stress and alcohol and tested if these associations differed for Black and White adults.ParticipantsParticipants were 229 adult drinkers (aged 21–35 years) who completed a larger study examining alcohol response for Black and White adults with and without a history of childhood ADHD.MeasurementsMomentary stress and alcohol craving, ADHD history and socio‐demographic characteristics (i.e. racial identity, sex, age, current education level, household income) were assessed. Participants were required to self‐identify as either ‘African American or Black’ or ‘European American or White’.FindingsSignificant racial identity × stress interactions indicated that associations between stress and craving were stronger for Black compared with White adults across the 10‐day period (between‐person: B = 0.14, P = 0.007), concurrently within a given EMA time‐point (within‐person: B = 0.04, P = 0.001) and prospectively from time‐point to time‐point (within‐person: B = 0.05, P = 0.001). Results remained while accounting for income × stress interactions.ConclusionsAcute stress appears to be more strongly related to alcohol craving in self‐identified Black compared with self‐identified White individuals. This provides support for policy changes to eliminate structural inequities that increase stress exposure and the development of just‐in‐time culturally responsive interventions focused on coping with acute stress for Black individuals.

AbstractBackground and AimsSobriety checkpoints are an effective strategy to reduce alcohol‐impaired driving, motor vehicle crashes, injuries and fatalities. The aim of this study was to identify the geographic extent over which individual sobriety checkpoints affect alcohol‐impaired driving.Design, Setting, ParticipantsSpatial ecological panel analysis using geolocated breath test data from the Queensland Police Service, Australia, for January 2012 to June 2018. Data were aggregated over 338 weeks within 528 Statistical Area level 2 (SA2) units (n = 178 464 SA2‐weeks) and 84 Statistical Area level 3 (SA3) units (n = 28 392 SA3‐weeks). SA2 units in Queensland contain a mean population of 8883.5 (SD = 55 018.3) and encompass 468.9 roadway kilometers (SD = 1490.0); SA3 units contain a mean population of 57 201.6 (SD = 29521.6) and encompass 2936.0 roadway kilometers (SD = 7025.0).MeasurementsIndependent measures were the density of sobriety checkpoints conducted per 500 roadway kilometers within local and spatially adjacent space–time units. The dependent measure was the rate of tests that detected breath alcohol concentration (a proxy for blood alcohol concentration [BAC]) greater than the legal maximum value of 0.05% for fully licensed drivers in Queensland. Bayesian hierarchical spatial negative binomial models‐related sobriety checkpoints to the rate of breath tests with BAC ≥ 0.05% within and between space–time units.FindingsOne additional sobriety checkpoint conducted per 500 roadway kilometers was associated with 2.5% reduction in the rate of breath tests with BAC ≥ 0.05% within local SA2 units (incidence rate ratio [IRR] = 0.975; 95% credibility interval (CrI): 0.973–0.978), and with 5.5% reduction in the rate of breath tests with BAC ≥ 0.05% within local SA3 units (IRR = 0.945; 95%CrI: 0.937–0.953). Associations were attenuated towards null in spatially adjacent units and in temporally lagged units (e.g. SA3‐weeks; adjacent lagged 1 week: IRR = 0.969; 95%CrI: 0.937–1.003).ConclusionsIndividual sobriety checkpoints appear to be associated with reductions in nearby alcohol‐impaired driving. Relationships decay after approximately 1 week and beyond local areas containing approximately 60 000 residents and 3000 kilometers of roadway.
Establishing the Queensland Pelvic Mesh Service: Preliminary experience
Authors: Tan Yu Hwee , Frazer Malcolm I. 
Published: December 2021

BackgroundTransvaginal mesh (TVM) has been used for treatment of pelvic organ prolapse (POP) and stress urinary incontinence (SUI). Mesh‐related complications are reported in 3% of women receiving mid‐urethral sling surgery for SUI and in up to 20% of women who receive TVM for POP. The Australian Senate Enquiry report in March 2018 recommended that each Australian state establish specialist multidisciplinary units for management of TVM complications.AimsThe aims of this study are to report on the setting up of the Queensland Pelvic Mesh Service (QPMS) and summarise its first 24 months to provide a potential framework for the establishment of similar service models within Australia and internationally.Materials and methodsThe planning and implementation of QPMS was a complex two‐stage co‐design process involving clinicians and consumers representing women with TVM complications. Consumer input in planning was important for the optimal establishment of QPMS to meet women’s holistic needs.ResultsFrom April 2019 to April 2021, 484 women had been treated by the medical team; 257 women had undergone cystoscopy and examination under anaesthesia; 91 patients had undergone mesh revision surgery – 65 complete excision and 25 partial excision and one sling division; and 180 women had been discharged from QPMS.ConclusionsProviding a comprehensive multidisciplinary service for managing TVM complications requires careful planning with consumer involvement before initiation. Addition of these patients to an existing service may not succeed. Emphasis on surgery may be misplaced for many. QPMS patients, as in sufferers with chronic pain conditions, benefit from psychological support and allied healthcare.

SummaryOur aim was to determine differences in the prevalence of mental health disorders between Black Americans living with sickle cell disease (SCD) and Black Americans with other, non‐heritable medical conditions, or no medical conditions. We examined the prevalence of mental health disorders among a non‐institutionalized, community sample of Black adults in the US from the National Survey of American Life. We compared the odds of mental health disorders between Black American adults with SCD and those with other medical conditions, or no medical condition. Among the SCD group, 38·8% reported at least one mental health disorder: 17·6% endorsed a mood disorder, 24·7% an anxiety disorder, 2·4% an eating disorder, and 11·8% a childhood disorder. Compared to those with other medical conditions, Black Americans with SCD had greater poverty, more children in the household, and were less likely to be married/cohabitating (all P < 0·05). Yet, Black Americans with SCD were not at greater odds of having a mental health disorder compared to those with other medical conditions. When compared to the group with no conditions, however, individuals with SCD had 2·57 greater odds of mood disorder (95% confidence interval: 1·43–4·65; P = 0·002). The effect remained when controlling for socioeconomic status, marital status, and perceived physical health. In this study, almost 40% of Black American adults with SCD presented with a mental health disorder. Prevalence of mental health disorders was similar among those with non‐heritable medical conditions, but those without a medical condition had a lower prevalence than in SCD. Among Black Americans, there appear to be unmeasured factors, common across medical conditions, that are linked to mental health disorders.

Published: December 2021

AbstractBackgroundAlthough children with spastic cerebral palsy (CP) commonly present with restricted passive range of motion (PROM) and contractures, knowledge about the child's characteristics that increase the risk of development of restricted PROM is limited. Identifying children who are more likely to develop contractures is important for early detection and the provision of appropriate medical management. This study aims to identify the most commonly restricted PROM of children with spastic CP and (2) to examine the combined effect of a child's age, gender, gross motor functional classification level and CP subtype on the development of restricted PROM in children with spastic CP.MethodsThe PROM of 233 children diagnosed with CP was extracted from the national registry of CP in Jordan (CPUP‐Jordan) in addition to information about children's age, gender, level of Gross Motor Function Classification System‐Expanded and Revised (GMFCS‐E&R) and subtype of CP. The mean age of the participants was 3.73 years (SD = 3.14), 57.5% were males and 80.3% had bilateral spastic CP. Point biserial correlations were calculated between the PROM and the child's variables. Multiple binary logistic regressions were conducted to identify the predictors of PROM.ResultsHip abduction was the most common restricted PROM (57.9%), whereas the hip extension was the least (2.1%). Children with older ages demonstrated more restrictions in knee extension and ankle dorsiflexion; males demonstrated more restriction in hip abduction than females; children with lower GMFCS‐E&R levels had more restrictions in hip internal rotation but fewer restrictions in hip abduction and ankle dorsiflexion; and children with bilateral spastic CP had more restrictions in hip abduction than children with unilateral spastic CP.ConclusionsPROM of the hip, knee and ankle joints of children with spastic CP was predicted by different sets of child characteristics. Implications for health professionals and follow‐up registries of children with CP are provided.
