Authors: Hu Qinfang , Yu Haowei , Wu Huirong , Chen Jing 
Published: March 2023

PurposeThis study aims to examine how implicit distance (cognitive and social) impacts supply chain capabilities, and the roles of information technology (IT) utilization and supply chain flexibility in this process.Design/methodology/approachThe authors designed a conceptual model including the implicit distance, supply chain flexibility, supply chain capability and IT utilization and verified the relationships among variables through a survey that collected data from 104 manufacturing enterprises in China.FindingsThe results show that cognitive and social distances positively and negatively affect supply chain flexibility, respectively. Furthermore, IT utilization strengthens the positive effect of cognitive distance and the negative effect of social distance on supply chain flexibility. Additionally, supply chain flexibility has a positive effect on supply chain capability and mediates the effects of cognitive and social distances on supply chain capability.Practical implicationsEnterprises should prioritize cooperation with different types of partners with whom the enterprises have established good collaborative working experiences. Moreover, if enterprises cooperate with new partners, enterprises should communicate and handle things face to face instead of frequently utilizing IT.Originality/valueThis study links the implicit distance between enterprises with supply chain capability and newly applies social network theory to explain the mechanism. Further, the authors' data confirm the moderating role of IT utilization in this process, supplementing the research on implicit distance. Moreover, this study employs dynamic capability theory to better understand how firms can improve supply chain capabilities.

Published: March 2023

PurposeRecently, the popularity of software has grown significantly in the market. Enhancement of software is needed to decrease the burden of getting high-quality and reliable software. To achieve this, the software is upgraded by adding new features to the previous version. Therefore, adding new features in the last version to be consistent with the earlier version is challenging. This paper aims to discuss the optimal software enhancement and customer growth model.Design/methodology/approachThis paper discusses a model when new features are added to the software, and the customers' adoption of the software is presented as a customer growth model. An optimal control problem is introduced to maximize the profit obtained from the software system over the system's lifetime period. Total gain is calculated by the value generated from selling the software over the total expenditure during the software development process. The closed-form solution and some theoretical results are presented using the optimal control-theoretic approach. The theoretical results are supported by a numerical example.FindingsThis paper gives several substantive insights during sensitivity analysis and provides essential results. The results discussed here are compatible with the actual scenario and useful in software enhancement.Originality/valueThe authors have proposed a new feature growth and customer growth model to maximize the total profit using optimal control theory.
On quality and complexity: non-conformance failures, management perspectives and learning outcomes on a highways megaproject

Published: March 2023

PurposeThe construction industry continues to struggle to deliver a right first time culture, seeking a panacea for improvement whilst maintaining project milestones. Complex construction projects demand stringent programmes, however, (un)foreseen changes, political influences and human behaviours all have significant impacts on delivering schemes without error. Previous studies have questioned the ability of the construction industry to successfully learn from errors. A major barrier has been the sharing of sensitive data from failed outcomes. Hence, this paper investigates non-conformance on an existing scheme and suggests avenues for improvement.Design/methodology/approachA mixed-method approach was adopted whereby 1,260 non-conformance reports (NCRs) from a highways megaproject were interrogated using root cause analysis (RCA) techniques to uncover the most frequent and costly areas. This was followed by a survey to industry professionals within a tier 1 principal contractor to gain insight into their perceptions of non-conformance and rework on construction projects.FindingsUsing Pareto analysis, the authors find that materials management, workmanship (poor quality execution) and supervision issues are the most frequently occurring and costly root causes of non-conformance on a major highways scheme. Furthermore, the authors link corresponding viewpoints of two project professional groups to the posed, achieving a high degree of consensus for the areas requiring development. Lastly, the authors suggest avenues for improvement via lessons learnt. These include greater emphasis on quality culture via a strong leadership mandate, enhanced vetting of workforce competence and improving the way materials are managed by embracing technology to drive efficiency.Originality/valueThis paper interrogates a current highways scheme using a uniquely rich, sensitive dataset to determine how the construction sector may improve efforts to achieving right first time outcomes.

PurposeVehicle lightweight design has positive implications for reducing energy consumption and abating greenhouse gas emissions. The traditional trailer axle design mainly focuses on the overall performance of the trailer axle. Only when the local performance does not meet the requirements will local performance optimization be done, such as local heat treatment to improve local strength. Such a design results in an uneven distribution of axle performance and excess performance in some local structures. The purpose of this study is to investigate the weight reduction on the premise of ensuring the structural dimensions of the outer surface of the axle remain unchanged and the reliability of the axle.Design/methodology/approachThe axle is parameterized by computer aided design, and the optimized axle finite element model based on computer aided engineering is established and verified by taking the eight dimensions of the axle cavity structure which affect the performance as parameters. A genetic algorithm is used to optimize the axle cavity structure size and axle weight based on multiobjective optimization, and eight optimized size parameters of axle cavity structure are obtained.FindingsThe total weight of the optimized axle of TM1314 is reduced by 10.2 kg, and the weight reduction ratio reaches 10.7%. According to the optimized structural size of the axle, the specimen was trial-manufactured, and the bench tests of stiffness, strength and fatigue life were carried out according to the test requirements of the trailer axle standard (JT/T 475-2002). The test results show that the maximum deformation of the specimen is 2.46 mm, the strength safety factor of the specimen body and the steel plate spring seat are 6.71 and 6.86 and bear the alternating load more than 1.05 × 106 times, which meets the standard of the trailer axle and is better than the original design requirements of the trailer axle.Originality/valueIn this study, the multiobjective optimization model of the axle is established, the response surface is constructed by the Latin hypercube sampling design method and the optimal solution set is obtained by the multiobjective genetic algorithm. It has been verified by bench tests that it can achieve a weight reduction of 10.7% under the premise of the same structure and size of the outer surface of the axle. The lightweight method based on multiobjective optimization proposed in this paper can provide a reference for the lightweight design of other key vehicle components.
Multi‐decadal stability of fish productivity despite increasing coral reef degradation
Authors: Yan Helen F. , Bellwood David R. 
Published: March 2023

Abstract

Under current trajectories, it is unlikely that the coral reefs of the future will resemble those of the past. As multiple stressors, such as climate change and coastal development, continue to impact coral reefs, understanding the changes in ecosystem functioning is imperative to protect key ecosystem services.

We used a 26‐year dataset of benthic reef fishes (including cryptobenthic fishes) to identify multi‐decadal trends in fish biomass production on a degraded coral reef. We converted fish abundances into estimates of community productivity to track the long‐term trend of fish biomass production through time.

Following the first mass coral bleaching event in 1998, the abundance, standing biomass and productivity of fish communities remained remarkably constant through time, despite the occurrence of multiple stressors, including extreme sedimentation, cyclones and mass coral bleaching events. Species richness declined following the 1998 bleaching event, but rebounded to prebleaching levels and also remained relatively stable.

Although the species composition of the communities changed over time, these new community configurations still maintain a steady level of fish biomass production. While these highly dynamic and increasingly degraded systems can still provide some critical ecosystem functions, it is unclear whether these patterns will remain stable over future decades.

Patterns of host–parasite coinvasion promote enemy release and specialist parasite spillover
Authors: Schatz Annakate M. , Park Andrew W. 
Published: March 2023

Abstract

Species invasion and redistribution, driven by climate change and other anthropogenic influences, alter global biodiversity patterns and disrupt ecosystems. As host species move, they can bring their associated parasites with them, potentially infecting resident species, or leave their parasites behind, enhancing their competitive ability in their new ranges. General rules to predict why invading hosts will retain some parasites but not others are relatively unexplored, and the potential predictors are numerous, ranging from parasite life history to host community composition.

In this study, we focus on the parasite retention process during host invasion. We used the Global Mammal Parasite Database to identify terrestrial mammal hosts sampled for parasites in both native and non‐native ranges. We then selected predictors likely to play a role in parasite retention, such as parasite type, parasite specialism, species composition of the invaded community, and the invading host's phylogenetic or trait‐based similarity to the new community.

We modelled parasite retention using boosted regression trees, with a suite of 25 predictors describing parasite and host community traits. We further tested the generality of our predictions by cross‐validating models on data for other hosts and invasion locations.

Our results show that parasite retention is nonrandom and predictable across hosts and invasions. It is broadly shaped by parasite type and parasite specialism, with more specialist parasites that infect many closely related hosts more likely to be retained. This trend is pronounced across parasite types; helminths, however, show a more uniform likelihood of retention regardless of specificity.

Overall, we see that most parasites are not retained (11% retained), meaning many invasive species may benefit from enemy release. However, species redistribution does have the potential to spread parasites, and this also has great relevance to understanding conservation implications of species invasions. We see that specialist parasites are most likely to coinvade with their hosts, which suggests that species closely related to the invasive hosts are most likely to be affected by parasite spillover.
Misunderstandings and misinterpretations: Antimicrobial use and resistance in salmon aquaculture

Published: March 2023

AbstractThe exponential growth of aquaculture over the past 30 years has been accompanied by a parallel increase in the use of antimicrobials. This widespread use has had negative effects on animal, human and environmental health and affected the biodiversity of the environments where aquaculture takes place. Results showing these harmful effects have been resisted and made light of by the aquaculture industry and their scientific supporters through introduction of misunderstandings and misinterpretations of concepts developed in the evolution, genetics, and molecular epidemiology of antimicrobial resistance. We focus on a few of the most obvious scientific shortcomings and biases of two recent attempts to minimise the negative impacts of excessive antimicrobial use in Chilean salmon aquaculture on human and piscine health and on the environment. Such open debate is critical to timely implementation of effective regulation of antimicrobial usage in salmon aquaculture in Chile, if the negative local and worldwide impacts of this usage are to be avoided.

AbstractTragocephala nobilis (Fabricius) (Coleoptera:Cerambycidae), an insect pest (herbivorous insect), was recently found on a multipurpose tropical tree species, Tetrapleura tetraptera (Schum and Thonn.) Taub, in Ghana. Although the pest has been previously reported on other tree crops such as cocoa and Coffea arabica, this is the first report on T. tetraptera. T. tetraptera is a deciduous tree crop with numerous nutritional and medicinal benefits. The pest, a long‐horned beetle is found to attack T. tetraptera tree and damage is first observed as die‐back of twigs and branches leading to the formation of a witches broom in the crown. This is followed by a series of tunnels created by the larvae on the main stem resulting in branch death and/or tree mortality. In view of the threat posed by the pest to T. tetraptera, a broader study is needed urgently to develop an integrated pest management strategy for T. nobilis pest in T. tetraptera plantations as the interest in its domestication as a tree crop is burgeoning in response to increasing herbal medicine and food supplements demand.

Published: March 2023

AbstractThe name “miombo” is a vernacular term for the forests in central, southern, and eastern Africa that are dominated by the closely related legume family genera Brachystegia, Julbernardia and/or Isoberlinia. Prescribed burning is a common management practice in most miombo woodland in protected areas that highly influences vegetation structure and composition which in turn influences small mammals' distribution and abundance. This practice if not checked might significantly affect the ecosystems. We investigated the effects of prescribed burning on rodent's ecology in the miombo woodland ecosystem in the Selous game reserve, Tanzania, between July 2018 and June 2020. A total of 473 individuals comprising six rodent species; Acomys ngurui (31.50%), Aethomys chrysophilus (28.96%), Mastomys natalensis (18.82%), Lemniscomys rosalia (14.16%), Mus minutoides (2.33%), Paraxerus flavovittis (0.85%) and two insectivorous shrew species; Petrodromus tetradactylus (3.17%) and Crocidura hitra (0.21%) were captured during 14,112 trap nights. There were no statistically significant differences in the abundance of A. ngurui between burnt and unburnt areas but its abundance was statistically significantly different between seasons. M. natalensis abundance was not statistically significantly different between burnt and unburnt areas or across seasons. The burnt sites had the highest species diversity than the unburnt in both wet and dry seasons. A. ngurui and M. natalensis survival and recruitment between burnt and unburnt sites were not statistically significantly different. The study shows that prescribed burning has an effect on specific species and demographic characteristics both positive and negative.

AbstractBackgroundDupilumab‐associated ocular surface disease (DAOSD) is frequently reported as side effect in atopic dermatitis (AD) patients. Therefore, the aim of this study was to investigate the frequency and severity of DAOSD, ophthalmic treatment response and to learn more about the effect of dupilumab on conjunctival goblet cells (GC).MethodsThis prospective study included dupilumab‐treated AD patients between February 2020 and June 2022 from the University Medical Centre Utrecht. Patients were examined by an ophthalmologist and a dermatologist before start (baseline), and after 4 and 28 weeks of dupilumab treatment. Ophthalmological examination was assessed by the Utrecht Ophthalmic Inflammatory and Allergic disease (UTOPIA) score. DAOSD was defined as an increase in UTOPIA score of ≥3 points from baseline. To quantify conjunctival GCs and to investigate the percentage of Cytokeratin 19 (CK19)‐CD45‐Mucin 5 AC (MUC5AC)+ cells, conjunctival impression cytology samples were analysed.ResultsOcular surface disease (OSD) was present in 91.3% (n = 63/69) patients at baseline. DAOSD was observed in 28.9% (n = 20/69) patients, in whom GC numbers remained stable and the percentage of CK19‐CD45‐MUC5AC+ cells decreased at onset of DAOSD compared with baseline. After 28 weeks of dupilumab treatment, DAOSD was seen in 14.5% (n = 10/69) patients. Of the 85.5% (n = 59/69) patients without DAOSD or with controlled DAOSD at Week 28, 40.7% (n = 24/59) patients received anti‐inflammatory ophthalmic drugs.ConclusionsOcular surface disease is common in moderate‐to‐severe AD patients before starting dupilumab. During treatment with dupilumab DAOSD severity improves with early ophthalmic treatment. The decrease in percentage of CK19‐CD45‐MUC5AC+ cells during dupilumab treatment suggests an impairment of the GC function due to dupilumab treatment.

Published: March 2023

AbstractBackgroundIn the United States, there are significant health inequities in perinatal care. This study examined differences in perinatal care provided to women based on the birthing person's designated race, within a large and diverse cohort of women.MethodsThis retrospective electronic medical record review identified patients receiving perinatal care within a large hospital system between January 2012 and September 2018 and examined associations between maternal designated race/ethnicity (Hispanic or non‐Hispanic [NH] Black, Asian or White) and various provider treatment decisions.ResultsThe study sample (N = 7056) was comprised of 36% Hispanic, 34% NH White, 21% NH Black, and 4% NH Asian women, aged 29.7 ± 6.3 years; 53% of the sample had private insurance, and 45% had Medicaid. Few differences by race were seen in perinatal care based on guidelines or expert recommendations (nondiscretionary care). Discretionary care, however, varied by race: Compared with NH White women, NH Black women were less likely to receive a prenatal depression screen (OR 0.8 [95% CI: 0.7, 0.9]) and more likely to have a urine drug test when denying drug use (OR 1.6 [95% CI 1.3, 2.0]), whereas Hispanic (OR 0.6 [95% CI: 0.5, 0.8]) and NH Asian (0.4 [95% CI 0.2, 0.9]) women were less likely to have a urine drug test completed when denying drug use.DiscussionPerinatal care differs by maternal race/ethnicity, particularly when guidelines or expert recommendations are absent. Greater efforts need to be made to identify and mitigate providers' implicit and explicit biases; expanded professional guidelines may offer some protections against inequitable, discretionary care.

AbstractIntroductionCannabis messaging on digital media may include sexualised portrayals. We examined whether exposure to and perceptions of cannabis posts that included sexual objectification impacted two types of sex‐related cannabis expectancies—sexual risk and sexual enhancement—and whether body appreciation moderated these relationships.MethodsWe conducted an online experiment with college students in Washington state. Participants viewed three brand‐generated cannabis Instagram posts that either included sexually objectified women or recreational appeals (e.g., sitting by a firepit). We conducted regressions, using the PROCESS macro, to examine the hypothesized model and potential mediation and moderation.ResultsExposure to sexualised advertisements was associated with increased perceptions of cannabis sex enhancement scripts (b = 0.34, p < 0.01), which was associated with increased cannabis sex enhancement expectancies (b = 0.34, p < 0.001) and decreased cannabis sexual risk expectancies (b = −0.16, p < 0.001); exposure to such advertisements were also associated with increased perceptions of cannabis sexual risk scripts (b = 0.61, p < 0.001), which was associated with increased cannabis sexual risk expectancies (b = 0.53, p < 0.001). Body appreciation was associated with increased cannabis sex enhancement expectancies (b = 0.13, p < 0.01) and moderated the relationship between exposure to sexualised ads and cannabis sex enhancement expectancies (b = −0.21, p < 0.01).Discussion and ConclusionsPractitioners may want to consider how to increase critical consumption of cannabis content on digital media. Researchers should consider the possible role of body appreciation as it relates to cannabis and sex enhancement expectancies.
