Published: December 2021

Purpose
The purpose of this study is to explore the association between intake of different types of dietary fats with breast cancer (BC) risk in Iranian women.

Design/methodology/approach
A total of 540 women (180 women with BC and 360 healthy women) were recruited from Shohadaye Tajrish hospital, Tehran, Iran. Data on anthropometric measurements, physical activity, smoking and alcohol consumption were collected. The food frequency questionnaire was used to assess the intake of fatty acids including saturated fatty acids, mono unsaturated fatty acids, poly unsaturated fatty acids, macronutrients, total fat, cholesterol, and calorie.

Findings
The cases had significantly higher BMI (29.19 ± 3.2 vs 27.27 kg/m2 ± 2.8) and higher intake of calorie (2737 ± 925 vs 2315 ± 1066 kcal/d, P = 0.01), carbohydrate (402 ± 125 vs 312 ± 170 kcal/d, P = 0.01) and ω−6 fatty acids (5.45 ± 6.9 vs 3.39 ± 0.59 g/d, P = 0.001) compared to the control group . Higher consumption of ω−6 fatty acids was related with higher risk of BC (OR = 5.429, CI95%:2.5–11.79, P = 0.001) The association between BC and intake of omega-6 fatty acids remained significant after adjustments for age, BMI, for using alcohol drinks, smoking, physical activity, calorie intake, protein intake and carbohydrate intake.

Originality/value
There are insufficient studies to investigate the association of different types of fatty acids with BC. This study found that higher omega-6 fatty acids intake was associated with increased risk of BC in women.
Does the expertise of outsourced IAF providers affect audit efficiency? Empirical evidence from an emerging market

Published: December 2021

PurposeThis study aims to examine the effect on audit efficiency of outsourced internal audit function (IAF) providers with industry and/or firm-specific expertise. Drawing on relevant studies from external and internal audit literature, the authors assume that such IAF providers are associated with greater audit efficiency as proxied by audit report lag and audit fees.Design/methodology/approachBased on a sample of firms listed on the Omani capital market during 2005–2019, the pooled regressions are used to test the developed hypotheses. The authors use the market share approach to identify outsourced IAF industry expertise providers and tenure to measure the firm-specific expertise of outsourced IAF providers.FindingsThe authors find that industry outsourced IAF providers are not associated with shorter audit report lag and lower audit fees. The authors also find that firm-specific expertise outsourced IAF providers are associated with a greater reduction in audit report lag and audit fees. These conclusions are robust under a battery of analyses. The significant contribution of firm-specific expertise outsourced IAF providers to audit efficiency is incremental when abnormal audit report lag and audit fees analysis is conducted.Originality/valueThe results are the first to attest to the contribution of outsourced IAF with firm-specific expertise. They also show that industry expertise held by outsourced IAF providers does not contribute to audit efficiency.
Bridging the employability skills gap: going beyond classroom walls
Authors: Tan Lin Mei , Laswad Fawzi , Chua Frances 
Published: December 2021

PurposeEmployability skills are critical for success in the workplace, even more so in this era of globalisation of economies and advancement in technologies. However, there is ample evidence of the gap between the skills acquired by graduates at universities and the skills expected by employers in the workplace. Applying the modes of grasping and transforming the experience embodied in Kolb’s experiential learning theory (ELT) (1976, 1984), the purpose of this paper is to examine the development of employability skills of accountancy students through their involvement in two extracurricular activities: community accounting and an accountancy club.Design/methodology/approachUnderpinned by Kolb’s (1976, 1984) four modes of ELT and work-integrated learning to develop professional competencies required for future work, an online survey of accounting students was conducted to assess their reflections on involvement in these two aforementioned extracurricular activities over a two-year period.FindingsThe findings indicate that the students had developed useful cognitive and behavioural skills from their participation in these extracurricular activities. These findings are consistent with the literature on internships and service-learning, both of which have been associated with transferable skills development.Originality/valuePrior studies focused on in-classroom learning activities or internships to help students develop various essential skills required in the workplace. However, extracurricular activities have received little attention in the accounting education literature. This study provides insights into skills accounting students can gain from extracurricular participation in community accounting and an accountancy club.
How can logistics service providers foster supply chain collaboration in logistics triads? Insights from the Italian grocery industry
Authors: Prataviera Lorenzo Bruno , Creazza Alessandro , Dallari Fabrizio , Melacini Marco 
Published: December 2021

Purpose
Collaborative solutions are increasingly being proposed to generate value in supply chains. Concurrently, firms have progressively outsourced logistics operations to logistics service providers (LSPs). However, many questions remain unsolved regarding the role played by LSPs in supporting supply chain collaboration (SCC) in triadic rather than dyadic contexts. This study aims to explore the relational mechanisms that LSPs can leverage to foster value creation through collaboration, elaborating on an existing theory about SCC by focussing on logistics triads.

Design/methodology/approach
By leveraging the view of the network theory, a multiple case study approach was adopted. Seven cases having logistics triads as units of analysis were identified and analysed within the Italian grocery supply chain, allowing for empirical investigation with a middle-range approach to extend the previous theory.

Findings
LSPs are pivotal actors that can actively promote SCC. LSPs can exploit large volumes and asset availability to increase efficiency while improving logistics flexibility and developing regular and trustworthy relationships with the other triad members. Building upon their logistics capabilities and the relational mechanisms in place, LSPs can help manufacturers collaborate with retailers by improving mutual trust and communication, acting as trust builders or trust conductors within the triad.

Originality/value
The study explores the role of LSPs in logistics triads, extending the previous literature. It highlights that LSPs facilitate not only supply and demand integration but also relational integration between firms. Trust emerges as a fundamental building block for SCC, as LSPs can look beyond economic benefits to foster partnerships that empower the co-development of original collaborative solutions.
Do pop-up ads in online videogames influence children’s inspired-to behavior?
Authors: Abbasi Amir Zaib , Rehman Umair , Ting Ding Hooi , Quraishi Muhammad Ali 
Published: December 2021

Purpose
Advertising through the videogame has become one of the most effective and prevalent channels of advertisement, especially via pop-up ads – appearing on the screen that interrupts children’s gaming activity. Despite its importance, the effectiveness of pop-up ads and its advertising value in online videogames (O-VGs) to predict children’s inspired-to behavior remains scant. This study aims to investigate the underlying factors that explain the relationship between the four dimensions of pop-up ads and perceived advertising value, which further predicts children’s inspired-to behavior.

Design/methodology/approach
Data from 196 parents who observed their children while playing O-VGs, were analyzed using Smart-PLS. As the respondents are parents, the authors took extra precautions to ensure that the findings are valid.

Findings
Results showed that perceived irritation and incentives of pop-up ads do not affect children’s advertising value, whereas perceived informativeness and entertainment of pop-up ads positively impact perceived advertising value among children. Besides, children’s perceived advertising value of pop-up ads in O-VGs predict their inspired-to behavior.

Originality/value
This study contributes to children’s inspired-to behavior via empirically studying the perceived advertising value as a potential deriving source of inspiration. Finally, the study provides information for developers/advertisers about why and under what circumstances children perceived advertising value affect inspired-to behavior.

Abstract

Dryland soils consistently exhibit a low capacity for the long‐term accumulation and storage of organic matter, which has been primarily attributed to low plant biomass inputs under drought suppression. Whether, and how, soil organic matter (SOM) compositions contribute to the consistently low SOM storage have been puzzling. A fundamental understanding of this mechanism is particularly essential to achieve the aspiration of ‘4 per mille Soils for Food Security and Climate’.

By screening the molecular composition of dissolved organic matter (DOM), the gatekeeper of SOM decomposition, we explored the transformation processes among the pools of SOM, DOM and microbial biomass carbon (MBC) in soils along a precipitation gradient on dryland grasslands of the Tibetan Plateau.

The results revealed that the number and mean weight of DOM molecules significantly decreased, and the soil DOM composition gradually shifted to be more labile along the transition from meadow, steppe, to desert with decreasing precipitation, coinciding with the substantial reduction in SOM. Compared with meadow soils, DOM degradability increased by 8.7% in steppe soils and by 23.4% in desert soils. The ratio of soil MBC to total organic carbon was threefold higher in desert than in meadow, and positively correlated with DOM degradability, indicating that labile DOM accelerated microbial growth and SOM decomposition in desert soils. Structural equation model and correlation analyses demonstrated that the DOM degradability was primarily controlled by soil dissolved nitrogen and soil organic C and soil DOC/DN ratio.

Synthesis and application. This study at a molecular level provides a novel insight into the important role of the degradability of dissolved organic matter in carbon accumulation in dryland soils with consistently low organic matter storage. The findings will inform better global managements of soil organic matter under consideration of both food security and climate change.
Complex co‐evolutionary relationships between cicadas and their symbionts

Published: December 2021

SummaryPrevious evidence suggests that cicadas lacking Hodgkinia may harbour the yeast‐like fungal symbionts (YLS). Here, we reinforce an earlier conclusion that the pathogenic ancestor of YLS independently infected different cicada lineages instead of the common ancestor of Cicadidae. Five independent replacement events in the loss of Hodgkinia/acquisition of YLS and seven other replacement events of YLS (from an Ophiocordyceps fungus to another Ophiocordyceps fungus) are hypothesised to have occurred within the sampled cicada taxa. The divergence time of YLS lineages was later than that of corresponding cicada lineages. The rapid shift of diversification rates of YLS and related cicada‐parasitizing Ophiocordyceps began at approximately 32.94 Ma, and the diversification rate reached the highest value at approximately 24.82 Ma, which corresponds to the cooling climate changes at the Eocene–Oligocene boundary and the Oligocene–Miocene transition respectively. Combined with related acquisition/replacement events of YLS occurred during the cooling‐climate periods, we hypothesise that the cooling‐climate changes impacted the interactions between cicadas and related Ophiocordyceps, which coupled with the unusual life cycle and the differentiation of cicadas may finally led to the diversification of YLS in Cicadidae. Our results contribute to a better understanding of the evolutionary transition of YLS from entomopathogenic fungi in insects.

Published: December 2021

AbstractIn most Latin American countries, there are significant numbers of missing people and forced disappearances, over 120,000 in Colombia alone. Successful detection of shallow buried human remains by forensic search teams is difficult in varying terrain and climates. Previous research has created controlled simulated clandestine graves of murder victims to optimize search techniques and methodologies. This paper reports on a study on controlled test site results over four simulated dismembered victims’ clandestine graves as this is sadly a common scenario encountered in Latin America. Multispectral images were collected once post‐burial, electrical resistivity surveys were collected 4 times, and ground penetrating radar (GPR) surveys were collected three times up to the end of the 371 day survey monitoring period. After data processing, results showed that the multispectral data set could detect the simulated clandestine and control graves, with electrical resistivity imaging relative high resistances over some of the simulated graves but not over the empty control graves. GPR results showed good imaging on the Day 8 surveys, medium imaging on the Day 294 surveys, and medium to good imaging on the Day 371 surveys. Study implications suggest that, while clandestine graves of dismembered homicide victims would likely result in smaller‐sized graves when compared to graves containing intact bodies, these graves can still potentially be detected using remote sensing and geophysical methods.
Cost and accessibility of empiric food elimination diets for treatment of eosinophilic oesophagitis
Authors: Sheedy Katherine , Patel Nishaat , Porter Judi , Silva Hannah 
Published: December 2021

AbstractAimThis study aimed to investigate and compare the cost, affordability, and accessibility of three elimination diet approaches for the treatment of patients with eosinophilic esophagitis: the two‐, four‐ and six‐food elimination diets and with comparison to a standard diet.MethodsAn evidence‐based modelling process was undertaken for costing and accessibility, including the development of three hypothetical reference families; four food baskets were modified from an established benchmark for each diet. Baskets were costed across eastern Melbourne, Australia. Affordability was modelled using two incomes: the equivalised disposable household income and welfare payments for reference families. Affordability was defined as <30% of the median weekly household income and food stress defined as >25% of a median weekly household income.ResultsAll elimination diets were significantly more expensive than a standard diet and may be unaffordable for those receiving welfare. Prices significantly increased as the number of food allergens eliminated increased. Most items for a two‐food elimination diet were available at major supermarkets; however, items for nutritionally complete four‐ and six‐food elimination diets required a visit to a second store.ConclusionA step‐up approach, commencing with a two‐food elimination diet, instead of starting with a six‐food elimination diet, may alleviate affordability barriers for most family types, which may enhance compliance. Clinicians should consider family type, financial situation, as well as accessibility of allergen‐free foods in the patient's residential area when deciding on the most appropriate dietary or therapeutic treatment approach for eosinophilic oesophagitis.

AbstractBackgroundThis study aimed to establish a predictive nomogram integrating epidermal growth factor receptor (EGFR) mutation status for 3‐ and 5‐year overall survival (OS) in unresectable/inoperable stage III non‐small cell lung cancer (NSCLC) treated with definitive chemoradiotherapy.MethodsA total of 533 stage III NSCLC patients receiving chemoradiotherapy from 2013 to 2017 in our institution were included and divided into training and testing sets (2:1). Significant factors impacting OS were identified in the training set and integrated into the nomogram based on Cox proportional hazards regression. The model was subject to bootstrap internal validation and external validation within the testing set and an independent cohort from a phase III trial. The accuracy and discriminative capacity of the model were examined by calibration plots, C‐indexes and risk stratifications.ResultsThe final multivariate model incorporated sex, smoking history, histology (including EGFR mutation status), TNM stage, planning target volume, chemotherapy sequence and radiation pneumonitis grade. The bootstrapped C‐indexes in the training set were 0.688, 0.710 for the 3‐ and 5‐year OS. For external validation, C‐indexes for 3‐ and 5‐year OS were 0.717, 0.720 in the testing set and 0.744, 0.699 in the external testing cohort, respectively. The calibration plots presented satisfying accuracy. The derivative risk stratification strategy classified patients into distinct survival subgroups successfully and performed better than the traditional TNM staging.ConclusionsThe nomogram incorporating EGFR mutation status could facilitate survival prediction and risk stratification for individual stage III NSCLC, providing information for enhanced immunotherapy decision and future trial design.
The age factor in optic nerve regeneration: Intrinsic and extrinsic barriers hinder successful recovery in the short‐living killifish

Published: December 2021

AbstractAs the mammalian central nervous system matures, its regenerative ability decreases, leading to incomplete or non‐recovery from the neurodegenerative diseases and central nervous system insults that we are increasingly facing in our aging world population. Current neuroregenerative research is largely directed toward identifying the molecular and cellular players that underlie central nervous system repair, yet it repeatedly ignores the aging context in which many of these diseases appear. Using an optic nerve crush model in a novel biogerontology model, that is, the short‐living African turquoise killifish, the impact of aging on injury‐induced optic nerve repair was investigated. This work reveals an age‐related decline in axonal regeneration in female killifish, with different phases of the repair process being affected depending on the age. Interestingly, as in mammals, both a reduced intrinsic growth potential and a non‐supportive cellular environment seem to lie at the basis of this impairment. Overall, we introduce the killifish visual system and its age‐dependent regenerative ability as a model to identify new targets for neurorepair in non‐regenerating individuals, thereby also considering the effects of aging on neurorepair.
