Operations-based classification of the bullwhip effect
Authors: Gupta Sachin , Saxena Anurag 
Published: September 2020

Purpose
Present study deals with the most discussed rather than addressed yet still an unsolved problem of supply chain known as the bullwhip effect. Operational variables affecting the bullwhip effect are identified and their role in causing the bullwhip effect has been explored using artificial neural networks. The purpose of this study is to analyze the impact of identified operational reasons that affect the bullwhip effect and to analyze the bunch of variables that are more prominent in explaining the phenomenon of the bullwhip effect.

Design/methodology/approach
Ten major sectors of the Indian economy are analyzed for the bullwhip effect in the present study, and the operational variables affecting the bullwhip effect in these sectors are identified. The bullwhip metric is developed as the ratio of variance in production to the variance in the demand. The impact of identified operation variables on the bullwhip effect has been discussed using the artificial neural network technique known as multilayer perceptron. The classification is also performed using neural network, logistic regression and discriminant analysis.

Findings
The operation variables are found to be varying with respect to sectors. The study emphasizes that analyzing the right set of operation variables with respect to the sector is required to deal with the complex problem, the bullwhip effect. The operational variables affecting the bullwhip effect are identified. The classification result of the neural network is compared with those of the logistic regression and discriminant analysis, and it is found that the dynamism present in the bullwhip effect is better classified by neural network.

Research limitations/implications
The study used 11 years of observations to analyze the bullwhip effect on the basis of operational variables. The bullwhip effect is a complex phenomenon, and it is explained on the basis of an extensive set of operational variables which is not exhaustive. Further, the behavioral aspect (bullwhip because of decision-making) is not explored in the present study.

Practical implications
The operational aspect plays a gigantic role to explain and deal with the bullwhip effect. Strategies to mitigate the bullwhip effect must be in accordance with the operational variables impacting the sector.

Originality/value
The study suggests a novel approach to study the bullwhip effect in supply chain management using the application of neural networks in which operational variables are taken as predictor variables.
Quality of life among patients with common mental disorders attending monk healers and primary care clinics in Thailand
Authors: Pengpid Supa , Peltzer Karl 
Published: September 2020

Purpose
Common mental disorders are not only highly prevalent in primary health-care settings but also negatively affect patients’ quality of life (QoL). This study aims to assess the levels of QoL among patients with common mental disorders seeking care from a monk healer or primary care setting and to determine the comparative QoL of users in two different types of care settings in Thailand.

Design/methodology/approach
Consecutively attending clients or patients (N = 1251) of three faith healing or three health centres were assessed with measures of depression, anxiety and somatization disorder and QoL.

Findings
The overall QoL was 67.8 and among the four QoL domains, social QoL was the highest (72.3), followed by physical QoL (69.4), environmental QoL (64.8) and psychological QoL (64.6). In adjusted linear regression analyses, sociodemographic factors, such as higher educational level, being employed, having high debt and consulting a health centre, were associated with higher overall QoL. Compared to being a client with a monk healer, patients at a health centre had a higher overall QoL, environmental and psychological QoL. Having a general anxiety or major depressive disorder was negatively associated with overall QoL and all four QoL sub-domains, whereas somatization disorder was not associated with any QoL sub-domains.

Originality/value
To the best of the authors’ knowledge, this is the first study to investigate QoL in common mental disorder attenders with a monk healer in comparison with primary care patients. Primary care patients with a common mental disorder had significantly higher overall QoL (p<0.01), higher psychological QoL (p<0.001) and higher environmental QoL (p<0.001) than clients with a common mental disorder attending monk healers. This study extends previous research showing a negative association between anxiety and depressive disorders and QoL calling for integration of QoL in the management of common mental disorders in both complementary and public primary care in Thailand.

Opening Up the “Black Box” of Audit Firms: The Effects of Audit Partner Ownership on Audit Adjustments
Authors: LENNOX CLIVE , WANG CHUNFEI , WU XI 
Published: September 2020

ABSTRACTAudit firms need to provide high‐quality audits but they also need to please their clients. We argue that these conflicting incentives become manifest when comparing the incentive effects of equity ownership on engagement quality (EQ) reviewers and audit engagement partners. We predict that EQ reviewers monitor audit quality more closely when they hold greater ownership. In contrast, we expect that equity ownership has conflicting effects on the incentives of engagement partners because they need to please their clients as well as provide high‐quality audits. Consistent with these predictions, we find that the associations between audit adjustments and partner equity ownership are (1) significantly positive for EQ reviewers, (2) significantly negative or insignificant for audit engagement partners, and (3) significantly more positive for EQ reviewers than engagement partners. Our findings suggest that larger ownership stakes motivate EQ reviewers to monitor audit quality more closely, whereas larger ownership stakes do not motivate engagement partners to deliver higher quality audits.

SummaryBackgroundIdentifying predictors of therapeutic response is the cornerstone of personalised medicine.AimTo identify predictors of long‐term healing of severe inflammatory lesions based on magnetic resonance enterography (MRE) findings in patients with Crohn’s disease (CD) treated with tumour necrosis factor alpha (TNF‐α) inhibitors.MethodsThis prospective longitudinal single‐centre study included patients with clinically active CD requiring treatment with TNF‐α inhibitors with at least one intestinal segment with a severe inflammatory lesion detected by MRE (segmental MaRIA ≥11). MRE data were obtained at baseline, and at weeks 14 and 46. The primary endpoint was healing of severe inflammatory lesions (MaRIA <11) in each segment. The secondary endpoint was healing of all severe inflammatory lesions on a per‐patient analysis.ResultsWe included 58 patients with 86 intestinal segments with severe inflammatory lesions. At week 46, healing of severe lesions was found in 51/86 (59.3%) segments, and complete healing of inflammatory lesions in all segments was found in 28/58 (48.6%) patients. Multivariable analysis found baseline‐negative predictors of long‐term healing of severe inflammation were ileal (as opposed to colonic) location (OR 0.00, [0.00‐0.56] P = 0.002) and presence of creeping fat on MRE (OR 0.00 [0.00‐0.57]; P = 0.001). Persistence of segmental MaRIA score >10.6 at week 14 was a negative predictor of healing at week 46 (OR 0.3 [0.04‐‐0.38]; P < 0.001).ConclusionIn patients with CD, the absence of creeping fat detected at baseline MRE and location of severe inflammatory lesions are clinically relevant predictors of long‐term healing of severe inflammation under treatment with TNF‐α inhibitors.

AbstractCardiopulmonary resuscitation (CPR) is a lifesaving emergency procedure. To increase survival rates, it is recommended to increase the number of high school students who know how to perform CPR. We have developed an immersive “Virtual Reality (VR) Resuscitation Training” to train the theoretical knowledge of CPR in which trainees must save the life of the patient in a virtual environment. This paper presents a randomized controlled study with a pre‐posttest design to explore whether a VR enhanced curriculum improves high school students’ theoretical CPR knowledge. Forty students without previous CPR experience in the past year were randomly assigned to either the VR group or the standard group. The VR group had a significant higher increase of correct answers in comparison with the Standard group. More importantly, the gain in score on taking the correct sequence of CPR steps was significant favouring the VR‐enhanced protocol over the Standard protocol. Therefore, the use of a VR training for CPR training appears to be an effective learning method for non‐medical students and may be of great value skilling high school students in becoming adequate CPR providers.
Practitioner NotesWhat is already known about this topic

CPR education leads to an increase in CPR knowledge and increases trainees’ willingness to initiate CPR in a real‐life situation.
Training CPR in a classroom setting has a lack of realism that bystanders experience during an actual life threatening situation. The experienced gap between the classroom and reality has a negative impact on self‐confidence which is known to be an important motive to actually initiate CPR.
Smartphone‐based VR combined with immersive scenarios has the ability to engage trainees in a real‐life setting using immersive interactive scenarios.
What this paper adds

This randomized controlled trial demonstrates that a VR enhanced curriculum results in a higher increase of CPR knowledge in comparison to a standard curriculum featuring an e‐learning with 2D videos.
This study shows that participants report higher self‐confidence in performing CPR.
Implications for practice and/or policy

VR training provides opportunities to keep CPR knowledge up to date to preserve self‐confidence in CPR‐providers.
VR immersive environments improve the learning experience significantly.

Sepsis remains to be a major contributor to mortality in ICUs, and immune suppression caused by immune cell apoptosis determines the overall patient survival. However, diagnosis of sepsis‐induced lymphopenia remains problematic with no accurate prognostic techniques or biomarkers for cell death available. Developing reliable prognostic tools for sepsis‐mediated cell death is not only important for identifying patients at increased risk of immune suppression but also to monitor treatment progress of currently trialed immunotherapy strategies. We have previously shown an important role for endoplasmic reticulum stress (ER stress) in inducing sepsis‐mediated cell death and here report on the identification of a secreted form of the ER chaperone BiP (immunoglobulin binding protein) as a novel circulating prognostic biomarker for immune cell death and ER stress during sepsis. Using biochemical purification and mass spectrometry coupled with an established in vitro sepsis cell death assay, we identified BiP/Grp78 as a factor secreted by lipopolysaccharide‐activated macrophages that is capable of inducing cell death in target cells. Quantitative ELISA analysis showed significantly elevated levels of circulating BiP in mice undergoing polymicrobial sepsis, which was absent in Bim−/− mice that are protected from sepsis‐induced lymphopenia. Using blood serum from human sepsis patients, we could detect a significant difference in levels of secreted BiP in sepsis patients compared to nonseptic controls, suggesting that secreted circulating BiP could indeed be used as a prognostic marker that is directly correlative to immune cell death during sepsis.

AimTo predict nurses’ intent to stay on the job as a function of organizational culture.BackgroundOrganizational climate significantly contributes to retention of nurses. Communication by conflict and organizational control over problem‐solving has not thoroughly been studied.MethodsA cross‐sectional design was used with a randomly selected final sample of 367 nurses from regional hospitals in Hungary. Organizational climate, perceived stress, locus of control and self‐esteem were assessed as main measures. Nurses indicated their intent to stay for the next 5 years. Spearman correlation coefficients were calculated to evaluate associations. Bivariate logistic regression was performed to predict intent to stay in nursing.FindingsOrganizational climate was negatively correlated with perceived stress and personal locus of control and positively with personal self‐esteem. Organizational level internal locus of control (belief that employees have control over problem‐solving) doubled the probability of staying on the job. Conflictual communication and perceived stress both decreased intent to stay by 50%.Discussion and conclusionsOrganizational internal locus of control, stress and conflictual communication were main predictors of intent to stay. The belief that nurses had collective control over problem‐solving capabilities had a positive and greater impact on nurse retention compared to other measures.Implication for nursing policyHealthcare organizations should routinely scan workplace culture for conflictual communication, stress and organizational problem‐solving capacities. Graduate nurse and nurse manager training should include practices that enable developing positive work atmospheres. Hospital managements should allocate training budget to stimulate and achieve cultural change.Implications for nursing practiceNurse managers should promote internal trainings to help staff nurses adopt techniques that minimize conflict and emphasize positive impact of collaborative problem‐solving.
The relationship among enterprise clustering, prices, and productivity in Ethiopia’s manufacturing sector

Published: September 2020

AbstractWe use census panel data on Ethiopian manufacturing firms to analyze how enterprise clustering in local markets covaries with firm‐level output prices and physical productivity. We find a negative and statistically significant relationship between the density of firms that produce a given product in a given location and the local price of that product. We also find a positive and statistically significant relationship between the density of firms that produce a given product in a location and the physical productivity of same‐product firms in the location. These results are consistent with the notion that increased clustering of firms generates higher competitive pressure and positive externalities. Across firms that produce different products, we find no statistically significant relationship between enterprise clustering and firm‐level output prices and productivity. We also find no clustering effects across towns. Our results suggest that while clustering can impact firm performance, the advantages are narrow in scope.

Published: September 2020

Abstract
Nitrate molten salt concentrating solar power (CSP) systems are currently deployed globally and are considered state-of the art heat transfer fluids (HTFs) for present day high-temperature operation. Although slightly higher limits may be possible with molten salt, to fully realize SunShot efficiency goals of $15/kWhth HTFs and an LCOE of 6¢/kWh, HTF technologies working at higher temperatures (e.g., 650 °C to 750 °C) will require an alternative to molten salts, such as with alkali metal systems. This investigation explores the development of a 2.0 MWth sodium receiver system that employs a sodium receiver as the HTF, as well as with a ternary chloride (20%NaCl/40%MgCl/40%KCl by mol wt.%) salt as a thermal energy storage (TES) medium to facilitate a 6-hr. storage duration. A sodium-to-salt heat exchanger model as well as a salt-to-sCO2 primary heat exchanger model are employed and evaluated in this investigation. A thermodynamic system design model was developed using Engineering Equation Solver (EES) where state properties were calculated at inlets and outlets along both hot and cold legs of the pilot-scale plant. This investigation assesses receiver performance as well as system efficiency studies for the pump and system operational ranges. Results found that high efficiency sodium receivers were found to have higher heat transfer coefficients and required far less spreading of incident flux. The system performance model results suggest that for a pump speed of 2400 RPM, respective hot and cold pump TDH values were determined to be 260.1–307 ft. and 260.1–307 ft for pump flow rates of 90–120 GPM.
High-Temperature Particle Flow Testing in Parallel Plates for Particle-to-Supercritical CO2 Heat Exchanger Applications

Published: September 2020

Abstract
Realizing cost-effective, dispatchable, renewable energy production using concentrated solar power (CSP) relies on reaching high process temperatures to increase the thermal-to-electrical efficiency. Ceramic based particles used as both the energy storage medium and heat transfer fluid is a promising approach to increasing the operating temperature of next generation CSP plants. The particle-to-supercritical CO2 (sCO2) heat exchanger is a critical component in the development of this technology for transferring thermal energy from the heated ceramic particles to the sCO2 working fluid of the power cycle. The leading design for the particle-to-sCO2 heat exchanger is a shell-and-plate configuration. Currently, design work is focused on optimizing the performance of the heat exchanger through reducing the plate spacing. However, the particle channel geometry is limited by uniformity and reliability of particle flow in narrow vertical channels. Results of high temperature experimental particle flow testing are presented in this paper.
