A Bayesian zero-one inflated beta modeling of dairy farmers’ decision to sell nothing or some output through contract farming
Authors: Ng'ombe John N , Kabwela Benny , Kiwanuka-Lubinda Rebecca N , Addai Kwabena Nyarko
Published: April 2022

Smallholder farmers’ preferences for participation in contract farming may take the form of proportional data––whereby farmers only sell some proportions or fractions of their output to contractors. We analyze determinants for preferences for zero (potential corner solution) and proportional amounts of milk that farmers sell through contract farming, using dairy farmers’ data from Zambia. Bayesian linear, linear probability, and hurdle models are compared with a Bayesian zero-one inflated beta regression. Monte Carlo simulations show that alternative models are biased. Meanwhile, empirical findings suggest that gender and marital status of the household head, household size, and delayed payment significantly drive preferences for proportional milk sales in contract farming. Additionally, household size, experience selling through milk collection centers, total livestock units, access to dairy marketing information, and a buyer's milk price, among others, tend to affect zero-inflated outcomes. We recommend a Bayesian zero-one inflated beta regression model for proportional data and also provide strategies to overcome farmer-engagement barriers in contract farming.

Authors: Zhao Xiaozhen , Zhang Junmei , Li Caifeng , Kuang Weiying , Deng Jianghong , Tan Xiaohua , Li Chao , Li Shipeng , Wang Jiang
Published: April 2022

Objective

To find indicators of disease severity and factors of early remission in patients with deficiency of adenosine deaminase 2 (DADA2).

Methods

We enrolled six DADA2 patients from six families. Direct sequencing of adenosine deaminase 2 gene (ADA2) was performed by Sanger analysis. A literature review was conducted for articles regarding paediatric DADA2.

Results

We found that more organs were involved in early-onset (≤1 year of age) than in late-onset (>1 year of age) DADA2 patients had high level inflammatory responses, such as elevated ESR, SF, serum amyloid A and CRP. Disease severity was not significantly different from missense and frameshift mutation. Early administration of TNF inhibitor might result in better remission and reduce recurrence. In the literature, four articles describing 51 paediatric DADA2 patients were identified. We also found that fever, stroke, peripheral nervous system involvement, hypogammaglobulinaemia and hypertension were more frequent in early onset DADA2 patients.

Conclusion

Early-onset DADA2 may be more severe. Early administration of TNF inhibitor can effectively reduce recurrence and quickly alleviate the disease.
Extent of vascular plaque predicts future cardiovascular events in patients with systemic lupus erythematosus
Authors: Bakshi Jyoti , Croca Sara C , Griffin Maura , Farinha Filipa , Isenberg David A , Nicolaides Andrew , Rahman Anisur
Published: April 2022

Objective

Patients with SLE have increased prevalence of clinical cardiovascular disease (CVD) and subclinical atherosclerosis. Although 30–40% of patients with SLE have vascular plaque on ultrasound scanning, this study is the first to consider the relationship between total burden of plaque and subsequent CVD risk.

Methods

One hundred patients with SLE and without any previous clinical CVD underwent vascular ultrasound scans of both carotid and both common femoral bifurcations between 2011 and 2013. Clinical, serological, demographic and treatment data were collected at baseline. Patients were followed till 2020 to identify those who developed new onset coronary disease or stroke. Statistical analysis to identify factors associated with increased risk of developing CVD events was carried out.

Results

Thirty-six patients had plaque at baseline. During follow-up five patients (all had baseline plaque) developed coronary disease and two, without baseline plaque, developed lacunar strokes. Mean (s.d.) age of these patients was 46.5 (4.5) years. Patients with three or more baseline bifurcations with plaque were 10 times more likely to develop CVD than those with 0–2 bifurcations with plaques (OR 9.9, P = 0.009). TPA > 16mm2 was associated with six-fold increased risk of CVD (OR = 6.44, P = 0.028). Patients with disease duration > 14 years were more likely than those with disease duration < 14 years to develop CVD (OR 8.3 P = 0.043)

Conclusions

The number of bifurcations with plaque and TPA in patients with SLE may be valuable in assessing risk of CVD and deciding on clinical measures to reduce this risk.

The development effort involved the study of aircraft dynamics and translating the equations of motion into MATLAB code. The authors also developed several auxiliary functions, so that the tool could trim the aircraft about a steady state, linearize the dynamic equations to produce a model that could be used for control systems design and carry out flight simulation.

Findings

MMC proved to be of good accuracy, producing results similar to those of other software such as AcuSolve, Overflow and the Rensselaer Multicopter Analysis Code (RMAC), which served as the motivation for this study.

Originality/value

The tool presented here provides an alternative to the aforementioned software, which are not freely available, programmed in MATLAB, a language well known to engineers and scientists.
“Same, same but different”: insights on ageing consumers and their expectations of institutional food
Authors: Andreassen Hanne , Gjerald Olga , MyrnesHansen Kai Victor
Published: April 2022

Purpose

Societies are experiencing a rapidly ageing population, which puts pressure on health services and institutions for the elderly. Ageing baby boomers have unique characteristics compared to previous generations, yet very little is known about these consumers' expectations of institutional food. The importance and issues with institutional food are well-recognized, and new approaches to improving institutional food offerings are warranted. The purpose of this study was to identify various segments of ageing consumers based on individual characteristics (entitlement, subjective food knowledge, disconfirmation sensitivity and age) and investigate differences in expectations between the groups.

Design/methodology/approach

Data were collected using a cross-sectional survey (n = 300) of ageing consumers (50–80 years old). A two-step cluster analysis was used to identify meaningful clusters.

Findings

A four-cluster solution was reached, with clusters (1) “Uninvolved oldies”, (2) “Humble old foodies”, (3) “Entitled youngsters” and (4) “Food experts”. This study found significant differences in expectations of institutional food between the clusters.

Practical implications

Recommendations for public policy implications for each segment are provided. This study contributes to preparing healthcare services and institutions to meet the institutional food expectations of various types of ageing consumers.

Originality/value

This paper measures ageing consumers' normative expectations of institutional food and concludes that expectations of food quality, freedom of choice, servicescape and sustainability differ by segments of ageing consumers.
Know your guests’ preferences before they arrive at your hotel: evidence from TripAdvisor
Authors: Rahimi Roya , Thelwall Mike , Okumus Fevzi , Bilgihan Anil
Published: April 2022

Purpose

Toward achieving a better guest experience, the current study aims to use the word frequency comparison technique to evaluate the types of attributes and services that are used most frequently in guests’ five- and one-star reviews on TripAdvisor. The working-paper also aims to investigate the differences between reviews written by men and women.

Design/methodology/approach

A combined sentiment and text analysis was applied to 329,849 UK hotel reviews from UK TripAdvisor to identify factors that influence customer satisfaction, including those with gender differences.

Findings

The present findings reveal important differences between the male- and female-produced terms. The results show that female travelers pay more attention to the hotel’s core products and their comfort compared to male travelers. In terms of food and beverage, men’s comments tended to focus on pubs, beer and certain types of food. In contrast, women’s comments were more likely to be related to healthy eating, such as homemade, vegan and vegetarian foods, as well as fruits and healthy breakfasts. Women also pay more attention to the soft skills of staff such as friendliness, helpfulness and welcoming messages.

Practical implications

While core attributes of a hotel stay remain crucial for all guests, disparities exist between the language men and women use to describe them. For core products, women pay more attention to the room’s cleanliness, comfort and features such as bed, pillow, blanket, towel, toiletries and decoration, whereas men pay more attention to the layout, size and type of room. Hotels may use gender as a segmentation variable and use these findings in their marketing campaigns.

Originality/value

This is one of the first studies offering insights into the differences between the male and female reactions to and preferences for hotel services at a national level. Following a novel method, this study has listed and ranked attributes and differentiated them based on gender.
The impact of project manager’s emotional intelligence on project performance: a meta-analysis
Authors: Zhang Qi , Hao Shengyue , Chung Kon Shing Kenneth
Published: April 2022

Purpose

A project manager’s (PM) emotional intelligence (EI) is essential for project performance (PP). However, the cause and effect and the potential moderators of the relationship between EI and PP remain disputed. Some scholars found a positive association between PMs’ EI and project outcomes, while some other studies showed non or negative relation. This paper aims to find the relationship between PMs’ EI and PP and the factors that influence this relationship based on diverse prior research.

Design/methodology/approach

This paper conducts a meta-analysis of 5,229 observations based on 24 independent studies from 1990 to 2021.

Findings

Results show that PMs’ EI has a significant positive influence on PP, and the project complexity and measurement of PP are two critical moderators explaining inconsistencies in existing research.

Practical implications

The current study proposes suggestions for construction companies on PMs’ selection and training. This study also offers suggestions for PMs in management practice.

Originality/value

To the best of the authors’ knowledge, this study is the first to explore the inconsistencies in prior research results on the relationship between PMs’ EI and PP at the meta-analytic level. This research extends the current literature by revealing the factors leading to existing consistencies that are not explored before. This study implies that the meta-analysis method could help reach a balanced conclusion based on inconsistent results.
Determination of maximum power point from photovoltaic system using genetic algorithm
Authors: Najdoska Angela , Cvetkovski Goga Vladimir
Published: April 2022

Purpose

The purpose of this paper is to present a novel approach to the determination of the maximum power point (MPP) in the photovoltaic system using genetic algorithm (GA). The optimization is realised on two types of photovoltaic (PV) modules: monocrystalline and polycrystalline solar modules, with the same rated peak power (400 Wp) but different electrical output data.

Design/methodology/approach

The proposed algorithm is a nature-based algorithm that uses genetic operators such as reproduction, crossover and mutation to realise the search through the investigated area of solutions. To determine the MPP of the PV modules, a two-diode model of a PV cell is used. Based on the input electrical data for the analysed PV module, as well as the mathematical model of the PV, the algorithm can estimate the current and voltage at the MPP for given solar irradiation and cell temperature. The analysis is made for several different irradiations, but in work, the results are presented for irradiations of: 100, 500 and 1,000 W/m2 and cell temperatures of 0, 25 and 40 °C.

Findings

From the presented results and performed analysis, it can be concluded that GA gives adequate results for both modules and for all working conditions. From the obtained results, it can be concluded that the optimization algorithm performs better when applied to the monocrystalline module works better especially in conditions with larger cell temperature, in comparison with the performance of the optimization algorithm applied to the polycrystalline module. On the other hand, the optimization algorithm applied to the polycrystalline module works better for the other working scenarios with smaller cell temperatures.

Practical implications

From the performed analysis, it can be concluded that the use GA as an optimization tool for the determination of the MPP can be successfully implemented. In addition, to improve the overall performance of the PV system, it is also necessary to forecast the weather conditions of the location where the PV system would be installed to forecast the cell temperature and the solar irradiation. This is necessary to choose the right PV module and inverter for the given location.

Originality/value

An optimization technique using GA as an optimization tool has been developed and successfully applied in the determination of the MPP for a PV system. The results are compared with the analytically determined values as well as with the values given by the producer, and they show good agreement.

Authors: Hadley Heidi Lyn
Published: April 2022

Purpose

This paper aims to examine how evangelical teachers’ religious identities influence their interpretation and teaching of texts in high school English Language Arts classrooms. Further, this paper examines how evangelical teachers make choices about how to balance the demands of their religious and teacher identities as they interact with texts in their own classrooms.

Design/methodology/approach

Using Derridean deconstruction of the concept of ethical decision-making, the author uses critical discourse analysis to examine a conversation between two evangelical teachers as they talk about the tensions they feel as they teachThe Cruciblewith their high school–aged students.

Findings

The findings show evangelical teachers’ religious and teaching identities were in tension across three themes: literary analytic frameworks, authorial intent and eternal truths and evangelism and fellowship.

Originality/value

By highlighting how evangelical teachers’ religious and teaching identities influence their classroom decisions, teaching practices and textual interpretations, this study offers another pathway through which teacher educators and researchers might examine the connection between teachers’ religious and teaching identities with the intent to invite more complexity into literary analysis.
Housing market price movements under tech industry expansion during COVID-19
Authors: Jiao Junfeng , Bhat Mira R. , Azimian Amin , Mandalapu Akhil , Farahi Arya
Published: April 2022

Purpose

This study aims to analyze the impact of technology-based corporation relocation on housing price indices during COVID-19 within the metropolitan areas of Austin, Texas and Seattle/Bellevue, Washington.The corporations under observation were Tesla and Amazon, respectively. The analysis intends to understand economic drivers behind the housing market and the radius of its effect while including fixed and random effects.

Design/methodology/approach

This study used a difference-in-difference (DID) method to evaluate changes in housing price index near and further away from Tesla’s and Amazon’s new corporate locations. The DID method allows for the capture of unique regional characteristics, as it requires a treatment and control group: housing price index and 5-mile and 10-mile search radii centered from the new corporate location.

Findings

The results indicated that corporate relocation announcements had a positive effect on housing price index post-pandemic. Specifically, the effect of Tesla’s relocation in Austin on the housing price index was not concentrated near the relocation site, but beyond the 5- and 10-mile radii. For Seattle/Bellevue, the effect of Amazon’s relocation announcement on housing price index was concentrated near the relocation site as well as beyond a 10-mile radius. Interestingly, these findings suggest housing markets incorporate speculation of prospective economic expansion linked with a corporate relocation.

Originality/value

Previous literature assessed COVID-19 housing market conditions and the economic effects of corporate relocation separately, whereas this study analyzed the housing price effects of corporate relocation during COVID-19. The DID method includes spatial and temporal analyses that allow for the impact of housing price to be observed across specified radii rather than a city-wide impact analysis.

Authors: Ascarya Ascarya , Husman Jardine A. , Tanjung Hendri
Published: April 2022

Purpose

This study aims to determine the characteristics of waqf-based Islamic financial institution (IFI) and subsequently propose some waqf-based IFIs.

Design/methodology/approach

This study uses the Delphi method, combined with the Likert scale, to determine and validate the agreed characteristics of waqf-based IFI models. Subsequently, based on the agreed characteristics, the authors propose waqf-based IFI models.

Findings

The results show that there are 28 important characteristics of waqf-based IFI, which respondents agree on 24 characteristics with significant Kendall’s concordance or rater agreement (W). The type of waqf-based IFI could be a bank, venture capital or cooperative; the business orientation should be a combination of commercial-social, and it could be implemented in the national, community or micro level. Based on the agreed characteristics, the authors propose several waqf-based IFI, including integrated commercial-social waqf-based bank, integrated commercial-social waqf-based venture capital and integrated commercial-social waqf-based cooperative.

Research limitations/implications

Respondents of this study comprise experts and practitioners who reside in Indonesia so that the results of proposed waqf-based IFIs are most suitable to be implemented in Indonesia.

Practical implications

The conceptual framework and method used in this study could be applied to determine the characteristics of waqf-based IFI and propose the most suitable waqf-based IFI models in other countries.

Optimization lubrication performance of journal bearings with microtexture
Authors: Wang Lili , Zhang Wei , Zhao Xingtang , Ge Xue
Published: April 2022

Purpose

Researchers have not reached an agreement on which biomimetic shape has the best lubrication performance. This paper aims to study the influence of microtexture size, shape and direction on bearing capacity, end leakage, friction coefficient and wear of oil film.

Design/methodology/approach

Different oil film thickness equations considering the microtexture of bearing surface are gained. The two-dimensional finite difference equation and the calculation equation of wear are established.

Findings

The theoretical research shows that the wear value and the wear ratio when long side is perpendicular to the axial direction of the bearing are generally lower than when the long axis is parallel to the axial direction of bearing. The theoretical and experimental results show that the appropriate microtexture shape, such as circular dimple, crescent-shaped dimple, triangular dimple and fish-shaped dimple can improve effectively the lubrication performance of journal bearing and reduce the friction coefficient.

Originality/value

The research has great significance to reduce friction and improve the wear resistance of equipment.

Authors: Schiavon Olívia Prado , May Márcia Ramos , Mendonça Andréa Torres Barros Batinga de
Published: April 2022

Purpose

The study aims to understand how dynamic capabilities (DCs) contribute to business model innovation (BMI) in sustainable family farming. The agrifood sector has been seeking solutions for the development of agroecological markets. Thus, the authors have analyzed the challenges imposed to innovation and sustainability strategic management and the value proposition to sustain the business over the years.

Design/methodology/approach

Considering the complexity of organizations and through an exploratory multiple case study of initiatives identified in the Organic Fair of Curitiba’s Passeio Público, it was possible to analyze the evolution of the business models (BMs) and the fair itself. Furthermore, it was possible to identify the DCs within the influence of agroecosystem elements on the innovation development.

Findings

Analyzing each case individually, the authors understood the different dimensions of the evolution of BMs considering the organizational complexity. The authors conclude that the balance between organizational practices and changes in the environment, engagement and learning plays a significant role in the developing competitive advantage. The same applies to the patterns that precede the development of DCs and BMs.

Originality/value

The article investigates innovation in agroecological BMs from a dynamic capability perspective. The agroecological BM is a subject that is still little discussed in the literature. In addition, the authors chose a context that includes socioenvironmental aspects and a few specificities of family farming in Brazil.

Authors: Fan Yunfei , Zhang Yilian , Jie Huang , Yue Tang , Bi Qingzhen , Wang Yuhan
Published: April 2022

Purpose

This paper aims to propose a novel model and calibration method to improve the absolute positioning accuracy of a robotic drilling system with secondary encoders and additional axis.

Design/methodology/approach

The enhanced rigid-flexible coupling model is developed by considering both kinematic parameters and link flexibility. The kinematic errors of the robot and the additional axis are considered with a model containing 27 parameters. The elastic deformation errors of the robot under self-weight of links and end-effector are estimated with a flexible link model. For calibration, an effective comprehensive calibration method is developed by further considering the coordinate systems parameters of the drilling system and using a two-step process constrained Levenberg–Marquardt identification method.

Findings

Experiments are performed on the robotic drilling system that contains a KUKA KR500 R2830 industrial robot and an additional lifting axis with a laser tracker. The results show that the maximum error and mean error are reduced to 0.311 and 0.136 mm, respectively, which verify the effectiveness of the model and the calibration method.

Originality/value

A novel enhanced rigid-flexible coupling model and a practical comprehensive calibration method are proposed and verified. The experiments results indicate that the absolute positioning accuracy of the system in a large workspace is greatly improved, which is conducive to the application of industrial robots in the field of aerospace assembly.

Expatriates' adjustment and performance in risky environments: the role of organizational support and rewards, risk propensity and resilience
Authors: Sarfraz Muhammad , Nisar Qasim Ali , Raza Ali
Published: April 2022

Purpose

Drawing upon the social exchange and psychological capital literature and applying a multilevel perspective, this paper examines how personal and organizational factors contribute to expatriates' adjustment and performance of international assignments in a terrorism-induced risky environment.

Design/methodology/approach

Data were collected using a non-probability sampling approach (e.g. purposive and subsequent snowball sampling). The authors tested the hypotheses using survey data of 138 expatriates with current international assignments in Pakistan.

Findings

Expatriates' perceived organizational and risk-taking propensity influences their performance through improved adjustment. Moderating effects suggest that an individual's satisfaction with the received organizational rewards strengthens the risk-taking propensity to adjustment relationship; resilience strengthens the adjustment to performance relationship.

Originality/value

This study extends existing expatriation literature by focusing on a specific type of risk factor pertinent to international assignments, i.e. terrorism. Integrating individual and organizational factors that influence adjustment and subsequent performance provides a clear picture rather if such factors are operationalized separately in the terrorism-induced risky environment context.
A review of knowledge hiding in team: evaluation of critical research streams
Authors: Fauzi Muhammad Ashraf
Published: April 2022

Purpose

The purpose of this paper is to systematically review knowledge hiding (KH) behaviors in the team context. KH behavior is regarded as unethical and antisocial behavior, detrimental to team development and performance. The nature of its existence should not be allowed in team activities.

Design/methodology/approach

Applying a systematic literature review, this study investigated 39 related quantitative studies on KH behavior of employees in team and group contexts. This study discusses the fundamental concept of KH, analyzes current research findings, identifies relevant gaps in the team and group context and sheds light on future direction.

Findings

Findings observed that the KH phenomena had gained the interest of scholars since the year 2010. Five main research streams identified in this systematic review are role of leadership, team creativity and innovation, underlying theory, multilevel modeling and KH scale.

Research limitations/implications

The value of this paper is subjected to the specific notion of KH in team background where knowledge sharing should have been promoted instead of KH. This systematic review serves as insight and recognition on the importance of mitigating KH in team. Existing current literature, future research work and trends of KH in the organization may benefit from this new and anticipated behavior within the knowledge management field.

Originality/value

To the best of the authors’ knowledge, this review is the first to review KH behavior in the team context.
Absorptive roots drive a larger microbial carbon pump efficacy than transport roots in alpine coniferous forests
Authors: Wang Qitong , Zhang Ziliang , Zhu Xiaomin , Liu Zhanfeng , Li Na , Xiao Juan , Liu Qing , Yin Huajun
Published: April 2022

Root activity creates a unique microbial hotspot in the rhizosphere and profoundly regulates soil carbon (C) dynamics, but empirical assessments of the soil microbial carbon pump (MCP, the iterative accumulation of necromass after microbial anabolism) and associated ecological consequences on soil C storage based on insight of the rhizosphere are still neglected, especially for different root functional modules.

We assessed the soil MCP efficacy (i.e. the contribution of microbial necromass to SOC) by investigating the divergent contribution of microbial necromass based on amino sugar extrapolations to soil organic C (SOC) in the rhizosphere of two root functional modules (i.e. absorptive roots and transport roots) and the bulk soil in an alpine coniferous forest.

The results showed that the MCP efficacy in both rhizosphere and bulk soil was more than 50%, suggesting that microbial necromass plays a key role in SOC formation. More importantly, absorptive roots drove a greater rhizosphere MCP efficacy (56%) than transport roots (51%).

Synthesis. These observations suggest that the microbial necromass is a major contributor to SOC storage in both rhizosphere and bulk soil in alpine coniferous forests. The magnitude of the contribution of microbial necromass to rhizosphere SOC depends on root functional differentiation. Our study provides novel and direct empirical evidence for the active soil MCP functions in SOC sequestration from the perspective of the rhizosphere.
Quantifying the economy‐wide returns to innovation for Australia
Authors: Wynn Katherine , Liu Mingji , Cohen Jasmine
Published: April 2022

Innovation plays a vital role in driving Australia's economic growth, and the desire to quantify this relationship is ever present. This article quantifies the relationship between domestic gross expenditure on research and development (R&D) and gross domestic product (GDP) per capita growth to estimate the return on investment (ROI) to innovation for Australia. This article adopts the Jones and Summers (2020) approach to quantify the ROI of gross R&D spending for Australia. This novel yet simple macroeconomic approach complements other existing methodologies. It quantifies only economic benefits, excluding non‐monetary societal and environmental benefits. The baseline results state that $1 of R&D investment creates an average of $20.8 in economy‐wide benefits in today's dollars, and investment in R&D creates an average annual return of 104% for Australia. Importantly, this baseline result can be recalculated with adjustments to account for specific features of innovation activity. Incorporating a 10‐year delay between R&D and payoffs, combined with a correction for building R&D into new capital inputs (known as embodied capital deepening) to account for the additional time and costs associated with R&D expenditure yields lower results of $3.5 of economy‐wide benefits and 10% average annual return for every dollar spent on R&D. Even when corrections are applied to the baseline for conservative estimates, the economy‐wide returns to innovation are comparable to historical private investment returns in Australia.
Cost‐effectiveness of an app‐based treatment for urinary incontinence in comparison with care‐as‐usual in Dutch general practice: a pragmatic randomised controlled trial over 12 months
Authors: Loohuis Anne M. M. , Van Der Worp Henk , Wessels Nienke J. , Dekker Janny H. , Slieker‐Ten Hove Marijke C. Ph. , Berger Marjolein Y. , Vermeulen Karin M. , Blanker Marco H.
Published: April 2022

Objective

To assess the cost‐effectiveness of app‐based treatment for female stress, urgency or mixed urinary incontinence (UI) compared with care‐as‐usual in Dutch primary care.

Design

A pragmatic, randomised controlled, superiority trial.

Setting

Primary care in the Netherlands from 2015 to 2018, follow‐up at 12 months.

Population

Women with ≥2 UI‐episodes per week, access to mobile apps, wanting treatment.

Methods

The standalone app included conservative management for UI with motivation aids (e.g. reminders). Care‐as‐usual delivered according to the Dutch GP guideline for UI.

Main outcome measures

Costs and cost‐effectiveness and ‐utility were assessed from a societal perspective, based on incontinence impact adjusted life years (IIALYs), quality adjusted life years (QALYs) and medical, non‐medical and productivity costs. Information on costs was obtained with the iMCQ and iPCQ questionnaires (medical consumption and productivity cost questionnaires).

Results

In all, 262 women were andomised equally to app or care‐as‐usual; 89 (68%) and 83 (63%) attended follow‐up, respectively. Costs were lower for app‐based treatment with € −161 (95% confidence interval [CI −180 to −151) per year. Cost‐effectiveness showed small mean differences in effect for IIALY (0.04) and QALY (−0.03) and thus larger incremental cost‐effectiveness ratios (ICER: −€3696) and incremental cost‐utility ratios (ICUR: €6379).

Conclusion

App‐based treatment is a cost‐effective alternative to care‐as‐usual for women with UI in Dutch primary care.

Tweetable abstract

App‐treatment for female urinary incontinence cost‐effective compared to care‐as‐usual in general practice after 12 months.
Impact ofDNAdamage response defects in cancer cells on response to immunotherapy and radiotherapy
Authors: Czajkowski Daniel , Szmyd Radosław , Gee Harriet E
Published: April 2022

The DNA damage response (DDR) is a complex set of downstream pathways triggered in response to DNA damage to maintain genomic stability. Many tumours exhibit mutations which inactivate components of the DDR, making them prone to the accumulation of DNA defects. These can both facilitate the development of tumours and provide potential targets for novel therapeutic interventions. The inhibition of the DDR has been shown to induce radiosensitivity in certain cancers, rendering them susceptible to treatment with radiotherapy and improving the therapeutic window. Moreover, DDR defects are a strong predictor of patient response to immune checkpoint inhibition (ICI). The ability to target the DDR selectively has the potential to expand the tumour neoantigen repertoire, thus increasing tumour immunogenicity and facilitating a CD8+ T and NK cell response against cancer cells. Combinatorial approaches, which seek to integrate DDR inhibition with radiotherapy and immunotherapy, have shown promise in early trials. Further studies are necessary to understand these synergies and establish reliable biomarkers.

Field beans (Vicia faba L.) are the most extensively grown grain legume in the UK but their contribution to farming and food systems could be improved if their yields were enhanced. Average on‐farm bean yields have varied between 3 and 4 t ha−1 for four decades but with much variation between individual crops. A “Bean Yield Enhancement Network” (Bean YEN) was initiated in 2019, supported by industry sponsors, to promote crop monitoring, sampling, and sharing of data between farms, thus learning about key yield‐affecting factors. Bean YEN continues, gathering new data annually; data from crops harvested in 2019 to 2021 are reported here. For each crop entered, data were collated on agronomy, soil, and weather, samples were analysed for height, nutrient content, yield components, and seed quality, and accurate yields were recorded. A localised biophysical yield potential (Ybp) was also estimated based on the best (repeatedly observed) resource capture and conversion coefficients and harvest index for beans, after accounting for costs of nitrogen (N) fixation. Over the three seasons, yields were collated from 26 winter bean and 63 spring bean crops, all well dispersed across the British Isles, with sufficient supporting information to make 87 estimates of Ybp. Average winter bean yields were 5.1 t ha−1 (range 1–8 t ha−1) and spring bean yields were 4.9 t ha−1 (range 1–7 t ha−1), respectively 38 and 43% of Ybp (13.7 & 11.2 t ha−1); yield shortfalls from Ybp averaged 7.2 t ha−1 (range 2.4–12.6 t ha−1). Yields correlated positively with plant height, thousand seed weight, total biomass shoot−1, seeds pod−1, harvest index and total straw biomass (t ha−1) in both winter and spring crops. In spring crops, the number of pods shoot−1 was also positively correlated with yield. Correlations suggested that growers could enhance yields by favouring an ideotype with deep roots, tall, multi‐noded stems, and prolonged canopy survival. This ideotype will be subject to modification and improvement after data are collected through future seasons of Bean YEN. The accumulating Bean YEN dataset is enabling benchmarks to be derived for crop attributes that should guide growers in their quest for sustained yield enhancements.
Why Fintech Is Not Changing Japanese Banking
Authors: Iwashita Naoyuki
Published: April 2022

Several years have passed since fintech first attracted attention in Japan. Although various new fintech services have emerged due to deregulation and policies to promote fintech's development and adoption, the overall composition and functioning of Japan's financial industry has not changed significantly despite fintech advances in other economies. The industry in Japan continues to be dominated by face‐to‐face interactions and has experienced little digitization. In Japan, sophisticated financial services were available before the widespread use of the internet, and most people have resisted conducting financial transactions using their smartphones. In addition, there has been almost no progress in digitizing accounting work in corporations. However, this stagnation in digitization on the demand side of financial services is changing for several reasons. Digitization in the government sector and the introduction of a new invoice system in 2023 will provide an opportunity for change. This time, Japan's financial services should undergo a significant digital transformation.

Published: April 2022

Low‐flow vascular malformations are rare congenital anomalies due to errors in vascular development and may be associated with known pathogenic genetic variants. Slow flow through the blood vessels can lead to localized intralesional thromboses, which can cause debilitating pain and impair quality of life. We present a case of venous malformation due to a variant in the TEK gene in a 38‐year‐old woman in whom treatment with low dose rivaroxaban was successful in controlling symptoms of chronic localized intravascular coagulation.
It's a guy thing: Sex as a moderator of the relationship between social anxiety and perception of interpersonal warmth in initial heterosexual interactions
Authors: Goh Pei Hwa , Ong Jonathan Z.
Published: April 2022

Social anxiety or the fear of being evaluated by others in social settings has been shown to contribute to impairments in interpersonal functioning. One way in which such impairments may arise is through biased perceptions of others during social interactions. The present study examined how social anxiety relates to the perception of interpersonal warmth from others within a relationship initiation context, and whether this relationship differs in men and women. Participants were 69 men and 69 women, aged 20.62 years on average (SD = 1.97), who identified as heterosexual. After completing a questionnaire pack online, participants engaged in a laboratory‐based interaction with a previously unacquainted participant of the other sex. After the interaction, participants reported their perception of their partner's warmth. Results revealed a negative association between men's degree of social anxiety and their perception of their partner's warmth. This association was not found in women. The moderation of sex on the role of social anxiety in interpersonal perceptions may reflect sex differences in social cognitive abilities.
Ultrasound‐guided caudal blockade and sedation for paediatric surgery: a retrospective cohort study

Data on safety and success rates of ultrasound‐guided caudal blockade, performed on sedated children with an uninstrumented airway, are scarce. We performed a retrospective observational study of validated data from April 2014 to December 2020 in a paediatric cohort where the initial plan for anaesthetic management was sedation and caudal epidural without general anaesthesia or airway instrumentation. We examined success rates of this approach and rates of block failure and block‐related complications. In total, 2547 patients ≤ 15 years of chronological age met inclusion criteria. Among the 2547 cases, including 453 (17.8%) former preterm patients, caudal‐plus‐sedation success rate was 95.1%. The primary anaesthesia plan was abandoned for general anaesthesia in 124 cases. Pain‐related block failure in 83 (3.2%) was the most common cause for conversion. Complications included 39 respiratory events and 9 accidental spinal anaesthetics. Higher odds of pain‐related block failure were associated with higher body weight (adjusted OR 1.063, 95%CI 1.035–1.092, p < 0.001) as well as with mid‐abdominal surgery (e.g. umbilical hernia repair) (adjusted OR 15.11, 95%CI 7.69–29.7, p < 0.001), whereas extreme (< 28 weeks) former prematurity, regardless of chronological age, was associated with higher odds (adjusted OR 3.62, 95%CI 1.38–9.5, p = 0.009) for respiratory problems. Ultrasound‐guided caudal epidural, performed under sedation with an uninstrumented airway, is an effective technique in the daily clinical routine. Higher body weight and mid‐abdominal surgical procedures are risk factors for pain‐related block failure. Patients who, regardless of chronological age, had been born as extreme preterm babies are at the highest risk for respiratory events.
