Pricing and inventory decisions in a manufacturer-Stackelberg supply chain with deteriorating items
Authors: Mahmoodi Anwar 
Published: October 2020

Purpose
Integrated decision of pricing and inventory control for a deteriorating product is known as a good practice in revenue management discipline. The purpose of this paper is to formulate the problem of joint pricing and inventory decision in a manufacturer–retailer supply chain with deteriorating items and backlogging. Furthermore, the other purpose is to develop an efficient algorithm to obtain the equilibrium solution.

Design/methodology/approach
In this study, a manufacturer–retailer supply chain of a deteriorating product is considered. The retailer aims to maximize his profit, for which he jointly determines the retail price and replenishment cycle. In addition, the manufacturer should decide on the wholesale price to maximize her profit. Considering the problem as a manufacturer-Stackelberg game, the equilibrium solution is formulated and analyzed for both the manufacturer and the retailer. Moreover, two different procedures are developed to obtain the equilibrium solution. The first procedure is an exact procedure for the Taylor-approximated model and the second is a simulated annealing (SA)-embedded algorithm for the actual model.

Findings
It is found that Taylor-approximated procedure is more accurate than SA-embedded procedure. However, the latter is more time-efficient. Moreover, it is observed that the obtained solution is highly sensitive to demand parameters, while it is not the case for the cost parameters.

Originality/value
The paper models a real industrial problem, and its results could be used in analyzing any manufacturer–retailer supply chain with deteriorating items. Among others, the fruit and vegetable supply chains are more likely to have a similar setting, and this study’s results are applicable for such chains in food industry.
Antecedents of green supply chain practices in developing economies
Authors: Upadhyay Arvind 
Published: October 2020

PurposeThis paper investigates the current state of green supply chain practices (GSCPs) and also introduces a framework for the implementation of GSCPs in India.Design/methodology/approachA case study approach was used for this research in which semi-structured interviews were conducted with three companies. These companies were automobile component manufacturing companies.FindingsIn the three case studies, there were different antecedents depending upon the specific company structure and organization. The ten GSCPs were used as a base for finding the antecedents.Research limitations/implicationsAlthough every step has been taken to ensure the rigour and reliability of case studies, in a field as complex as GSCPs, there are inevitably some limitations. Due to the limited size of the case study approach, the results can only be generalized to a similar size and types of organization. The scope of data collection for all three case studies was the same, but the quality of information gathered varied. As demonstrated earlier, a good-quality cross-case analysis was still possible, but the relative strengths of the three cases varied.Practical implicationsA double contribution has been made to test the theory of GSCPs from a process and output perspective. From a process perspective, a contribution has been made to methodology by developing a robust approach for conducting supply chain research beyond the dyad. From an output perspective, the author has the empirical results from the three individual case studies and their cross-case comparison for dissemination to an academic audience.Originality/valueThe outputs of this research work will pave a path for other automobile component manufacturing companies in India to address and implement GSCPs.
Research watch: tackling everyday exclusion
Authors: Holttum Sue 
Published: October 2020

Purpose
This paper aims to examine three recent papers on discrimination and exclusion that happen on a day-to-day basis in social interactions, known as micro-aggressions.

Design/methodology/approach
The author searched for recent papers on discrimination in the databases Psyc INFO and ASSIA. Three papers were selected addressing a common theme published within the past 24 months.

Findings
All three papers concern a US context. The first reports experiences of women with physical disabilities in relation to micro-aggressions. Based on focus groups with 30 women, micro-aggressions appear to be common and some cause considerable distress. The second paper reports experiences of 65 mental health peer support workers in a range of mental health services and finds micro-aggressions common for them too. The third paper goes beyond occurrence and type of micro-aggressions. Based on existing research, it proposes how members of marginalised racial groups can tackle micro-aggressions, whether they are the target, an ally or a bystander.

Originality/value
These papers show clear examples of micro-aggressions, making them easier to see. While the first two papers are each the first to document micro-aggressions for specific marginalised groups, the third paper is the first to bring together practical ways to tackle micro-aggressions in day-to-day life. There is potential for this to help bring about increased social inclusion and equity for a range of marginalised groups, and for a resultant benefit in the mental and physical well-being of many people.
The UK's largest volume housebuilders and the sustainable development goals
Authors: Jones Peter , Comfort Daphne 
Published: October 2020

PurposeThe sustainable development goals (SDGs) agreed at a United Nations General Assembly in 2015 embrace an ambitious and wide ranging set of global environmental, social and economic issues designed to effect a transition to a more sustainable future. The United Nations called on all governments to pursue these ambitious goals but also acknowledged the important role of the private sector in addressing the SDGs. This paper offers an exploratory review of how some of the UK's largest volume housebuilders publicly claim to be committed to addressing the SDGs.Design/methodology/approachThe paper provides an outline of the characteristics of sustainable development, of the SDGs and of the frame of reference and method of enquiry employed in the study, prior to reviewing the findings from the largest UK housebuilders.FindingsThe findings revealed that seven of the largest housebuilding companies claimed to be committed to contributing to the SDGs, though the scale and the extent of their claimed commitments varied. In reviewing the housebuilders approach to the SDGs, the authors drew attention to three challenges the housebuilders may face in pursuing their claimed commitment to the SDGs, namely, concentrating on specific goals, measurement and reporting.Originality/valueThe paper offers an accessible review of how seven of the UK's largest housebuilders claimed to be committed to addressing the SDGs.
Role stressors and turnover intention among doctors in Malaysian public hospitals: work–family conflict and work engagement as mediators
Authors: Harun Ifrah , Mahmood Rosli , Md. Som Hishamuddin 
Published: October 2020

PurposeThis study aims to investigate the role of work–family conflict (WFC) and work engagement (WE) and its influence on role stressors and turnover intention among medical doctors in Malaysian public hospitals. Doctors who experience higher work stress will inevitably experience WFC, consequently triggering their intention to quit.Design/methodology/approachA total of 202 structured questionnaire responses were collected from medical doctors in four Malaysian public hospitals. The study used partial least squares structural equation modeling (SmartPLS 3.0) for hypotheses testing.FindingsAs hypothesized, WFC encourages turnover intention while WE mitigate the relationship between role ambiguity (RA)-TI. RA is also observed to reduce WE, which, in turn, increases the intention to quit. Findings showed that both role conflict and WFC share a positive relationship with TI while WE and TI are negatively related. Furthermore, it was found that WE and WFC are significant mediators in the RA and TI relationship. WFC is also reported to be a significant mediator between the RC and TI relationship.Research limitations/implicationsThe causality effects remain limited due to the nature of the cross-sectional design. Future studies should use a longitudinal approach to gauge a better understanding of these relationships.Practical implicationsThis study provides insights for policymakers in resolving the increase of turnover issues by providing support and relieving medical doctors’ stress levels. Health directors should be encouraged to focus on the key aspects that may directly affect the well-being of medical doctors and eventually reduced staff turnover.Originality/valueThe study contributes to existing knowledge by measuring variables such as job demand (RS and WFC), personal resources (WE) and job outcomes (TI) in the public health care sector. Additionally, research involving COR theory in Asian countries like Malaysia remains relatively underexplored.
The Role of Value‐Based Payment in Promoting Innovation to Address Social Risks: A Cross‐Sectional Study of Social Risk Screening by US Physicians
Authors: BREWSTER AMANDA L. , FRAZE TARESSA K. , GOTTLIEB LAURA M. , FREHN JENNIFER , MURRAY GENEVRA F. , LEWIS VALERIE A. 
Published: October 2020

Policy Points
One of the most important possibilities of value‐based payment is its potential to spur innovation in upstream prevention, such as attention to social needs that lead to poor health. Screening patients for social risks such as housing instability and food insecurity represents an early step physician practices can take to address social needs.
At present, adoption of social risk screening by physician practices is linked with having high innovation capacity and focusing on low‐income populations, but not exposure to value‐based payment.
Expanding social risk screening by physician practices may require standardization and technical assistance for practices that have less innovative capacity.
ContextOne of the most important possibilities of value‐based payment is its potential to spur innovation in upstream prevention, such as attention to social needs that lead to poor health. However, there is uncertainty about the conditions under which value‐based payment will encourage health care providers to innovate to address upstream social risks.MethodsWe used the 2017‐2018 National Survey of Healthcare Organizations and Systems (NSHOS), a nationally representative survey of physician practices (n = 2,178), to ascertain (1) the number of social risks for which practices systematically screen patients; (2) the extent of practices’ participation in value‐based payment models; and (3) measures of practices’ capacity for innovation. We used multivariate regression models to examine predictors of social risk screening.FindingsOn average, physician practices systematically screened for 2.4 out of 7 (34%) social risks assessed by the survey. In the fully adjusted model, implementing social risk screening was not associated with the practices’ overall exposure to value‐based payment. Being in the top quartile on any of three innovation capacity scales, however, was associated with screening for 0.95 to 1.00 additional social risk (p < 0.001 for all three results) relative to the bottom quartile. In subanalysis examining specific payment models, participating in a Medicaid accountable care organization was associated with screening for 0.37 more social risks (p = 0.015). Expecting more exposure to accountable care in the future was associated with greater social risk screening, but the effect size was small compared with practices’ capacity for innovation.ConclusionsOur results indicate that implementation of social risk screening—an initial step in enhancing awareness of social needs in health care—is not associated with overall exposure to value‐based payment for physician practices. Expanding social risk screening by physician practices may require standardized approaches and implementation assistance to reduce the level of innovative capacity required.

Published: October 2020

AbstractBackgroundRheumatoid arthritis (RA) is an autoimmune disease with varied articular and extra‐articular manifestations. In developing countries such as India patients with RA often delay seeking medical advice which may impact prognosis and disease burden.AimTo explore perceptions and experiences of patients living in India in seeking medical help for their RA symptoms.MethodsClinician‐diagnosed RA participants from different socioeconomic backgrounds were interviewed using a semi‐structured topic guide. Participants were purposively selected and interviewed following an iterative approach. All interviews were recorded and transcribed by an independent company and analyzed using a thematic framework. Findings were reported in accordance with consolidated criteria for reporting qualitative research guidelines.ResultsTwenty participants (13 male, 7 female) with median age 40 years (35.7‐46.5) were recruited. Three overarching themes demonstrating participants’ experiences and reasons for delay in seeking medical help were identified. (1) “Symptoms perspectives and delay in participants’ journey” narrated participants’ experiences of having RA symptoms, how these were perceived, rationalized and led to delay. (2) “Participants’ experience of the healthcare system” illustrated delay in referral, reaching diagnosis and treatment initiation highlighting their experiences with the health system. (3) “Recommendations for improving care” where participants made recommendations for reducing the delay at local and national levels.ConclusionThis is the first qualitative study which explored perceptions and experiences of RA patients in India resulting in delay. Improved provision of rheumatology care, effective referral system and greater involvement of government at local and national levels are needed to improve the delay in seeking medical help for Indian patients.
Quantifying the impact of an inference model in Bayesian phylogenetics
Authors: Bilderbeek Richèl J. C. , Laudanno Giovanni , Etienne Rampal S. 
Published: October 2020

Abstract

Phylogenetic trees are currently routinely reconstructed from an alignment of character sequences (usually nucleotide sequences). Bayesian tools, such as MrBayes, RevBayes and BEAST2, have gained much popularity over the last decade, as they allow joint estimation of the posterior distribution of the phylogenetic trees and the parameters of the underlying inference model. An important ingredient of these Bayesian approaches is the species tree prior. In principle, the Bayesian framework allows for comparing different tree priors, which may elucidate the macroevolutionary processes underlying the species tree. In practice, however, only macroevolutionary models that allow for fast computation of the prior probability are used. The question is how accurate the tree estimation is when the real macroevolutionary processes are substantially different from those assumed in the tree prior.

Here we present pirouette, a free and open‐source r package that assesses the inference error made by Bayesian phylogenetics for a given macroevolutionary diversification model. pirouette makes use of BEAST2, but its philosophy applies to any Bayesian phylogenetic inference tool.

We describe pirouette’s usage providing full examples in which we interrogate a model for its power to describe another.

Last, we discuss the results obtained by the examples and their interpretation.

AbstractBackground and aimsNot all people experiencing opioid dependence benefit from oral opioid agonist treatment. The aim of this study was to examine perceptions of (supervised) injectable opioid agonist treatment (iOAT) (described as ‘an opioid similar to heroin self‐injected at a clinic several times a day’) among people who regularly use opioids and determine how common iOAT eligibility criteria accord with interest in iOAT.DesignCross‐sectional surveySettingSydney, Melbourne and Hobart, AustraliaParticipantsA total of 344 people (63% male) who use opioids regularly and had ever injected opioids, interviewed December 2017–March 2018. The mean age of participants was 41.5 years [standard deviation (SD) = 8.5].MeasurementsPrimary outcome measures were interest in iOAT, factors associated with interest and the proportion of participants who would be eligible using common criteria from trials and guidelines. We examined willingness to travel for iOAT, medication preferences and perspectives on whom should receive iOAT.FindingsOverall, 53% of participants (n = 182) believed that iOAT would be a good treatment option for them. Participants who believed that iOAT was a good treatment option for them were more likely to be male [adjusted odds ratio (aOR) = 1.76, 95% confidence interval (CI) = 1.10–2.82], have used heroin in the past month (aOR = 6.03, 95% CI = 2.86–12.71), currently regularly inject opioids (aOR = 1.84, 95% CI = 1.16–2.91) and have met ICD‐10 criteria for opioid dependence (aOR = 3.46, 95% CI = 1.65–7.24). Those interested in iOAT had commenced more treatment episodes (aOR =1.06, 95% CI = 1.00–1.12). Among those interested in iOAT (n = 182), 26% (n = 48) met common eligibility criteria for iOAT.ConclusionsInterest in injectable opioid agonist treatment does not appear to be universal among people who regularly use opioids. Among study participants who expressed interest in injectable opioid agonist treatment, most did not meet common eligibility criteria.
Spatial distribution, sampling efficiency and Taylor's power law. 2. Interpreting density‐dependent sampling efficiency
Authors: Taylor R. A. J. 
Published: October 2020

AbstractThe intimate relationship between sampling efficiency and Taylor's power law (TPL) was investigated with gypsy moth sample data. The data were used to compute sampling efficiency directly and indirectly by TPL.
Comparison of TPLs and efficiency plots of male and female pupae confirmed the identities linking TPL with sampling efficiency. Divergence of sex‐specific TPL plots indicated local scale density‐dependent sex ratio.
Egg mass sample data confirmed the sampling efficiency and TPL identities provided the same variance and mean vectors were used to compute TPLs. Small differences in sample numbers destroy the identities but approximate efficiency estimates are still obtainable from the TPLs. Sampling efficiency of timed walks, fixed area and variable area surveys were estimated and ranked.
Rescaling moth catches per trap to number per unit volume changes slope, intercept and correlation coefficient while stretching the pattern of data points. Comparison of absolute density estimates over two different time intervals showed density‐dependent variation declining with increasing sample interval.
Fitting power laws by ordinary dependent regression is less efficient than fitting by geometric mean regression and produces biased regression parameters. The significance of this for the analysis and interpretation of ecological sample data generally is discussed.
What Motivates Reasoning? A Theory of Goal‐Dependent Political Evaluation
Authors: Groenendyk Eric , Krupnikov Yanna 
Published: October 2020

AbstractRather than exhibiting bias or open‐minded reasoning at baseline, we argue that information processing is motivated by whatever goals a context makes salient. Thus, if politics feels like debate, people will be motivated to argue for their side. If politics feels like deliberation, they will be motivated to seek consensus through open‐minded processing. Results from three experiments demonstrate: (1) Politics evokes thoughts similar to conflictual contexts and dissimilar from deliberative contexts. (2) Consequently, information labeled “political” primes the motivation to counterargue, leading to opinion polarization. Absent such labeling, no such motivation is evident, explaining why bias is common but not inherent to politics. (3) Despite this capacity for bias, people can be motivated to actively process and accept counterattitudinal information by simply making the value of open‐mindedness salient. This suggests open‐minded discourse is possible even absent motivation to evaluate information accurately. We conclude by discussing the implications of our research for political discourse.

Published: October 2020

ObjectivesConsistent with behaviour observed in prior crises, individuals are stockpiling supplies during the novel coronavirus (COVID‐19) pandemic. The goal of this study was to describe stockpiling behaviour in response to COVID‐19 and investigate individual predictors of stockpiling.MethodsWorkers (N = 363, 54.72% male, 44.65% female, 0.63% other; Mage = 38.41, SD = 12.48, range = 18‐78) were recruited from Amazon’s Mechanical Turk and completed a survey about their stockpiling of 13 items, as well as behaviours and opinions surrounding the COVID‐19 pandemic and their political affiliation.ResultsParticipants stockpiled, on average, approximately 6 items, and toilet paper was the item most commonly procured. Approximately 25% of the sample acquired a gun or other weapon in response to the pandemic and approximately 20% of participants stockpiled gold or other precious metals. Stockpiling was more commonly observed among individuals who were more conservative, worried more about the pandemic, and social distanced less.ConclusionsIndividual, societal, and ideological implications are discussed.
