Factors forming consumer willingness to pay a premium for free-range eggs
Authors: Slack Neale J. , Sharma Shavneet , Cúg Juraj , Singh Gurmeet
Published: December 2022

Purpose

Little is known about the external stimuli, which trigger a change in a consumer's cognitive and affective state and lead to a consumer's willingness to pay a premium price (WTPPP) behavioural response. This study aims to close this knowledge gap by providing insight into how a unique combination of antecedents affects consumer attitude toward purchasing free-range eggs and leads to a behavioural response, which is measured by consumer WTPPP for free-range eggs.

Design/methodology/approach

An online questionnaire was developed, with data collected from 392 Australian consumers. This study employs confirmatory factor analysis (CFA) to examine the measurement model before testing the hypothesised relationships using covariance-based structural equation modelling (CB-SEM).

Findings

The study reveals that the tested customer perceived value (CPV) dimensions, animal welfare and source credibility are positive stimuli of consumer attitude towards purchasing free-range eggs, which subsequently promotes consumer WTPPP for free-range eggs.

Research limitations/implications

Findings drawn from Australian consumers may not be generalisable to consumers from disparate contexts, and stimuli beyond those tested may influence consumer attitude and WTPPP.

Originality/value

This is one of the first studies to use the stimulus–organism–response (SOR) theory to investigate and contribute to extant knowledge and understanding of consumer behaviour relating to free-range eggs and specifically of consumer attitude towards purchasing and WTPPP for free-range eggs. This study offers practical implications for free-range egg farmers, retailers and policymakers.
The surplus food donation for retail circular economy transition: the case of Coop Alleanza 3.0
Authors: Di Noia Alfredo Ernesto , Nicoletti Giuseppe Martino , Cappelletti Giulio Mario , Ioppolo Giuseppe
Published: December 2022

Purpose

This study examines the relationships between the sizes of Coop Alleanza 3.0 retail outlets and indicators (in value) of surplus food (SF), real food donation (FD) and potential food waste (FW) from 2013 to 2019.

Design/methodology/approach

Retail outlets were grouped by size class and geographic macro-area. The authors adopt a procedure composed of Kendall's tau-b coefficient with ties (ttest) and the coefficient of determination (R²). The authors studied bread, pastries, fruits and vegetables as representative food categories.

Findings

Among the hypermarket group (Emilia-Romagna Region and those in group with Apulia Region), the study found the t-test with many high negative relationship and related R2 high. Results showed that size significantly influenced the trends of the indicators for the food categories analyzed. This allowed the authors to hypothesize the presence of inefficiencies in these groups.

Originality/value

From a practical point of view, the procedure can provide Coop Alleanza 3.0, with a dashboard to analyze surplus food management (SFM) progress within its retail groups. This can provide a warning signal (WS) to trigger a management control system. If necessary, it can lead to corrective measures, such as internal optimization, by adopting appropriate work procedures. In this sense, the procedure is scalable and transferable at the international middle and micro-scales. This approach facilitates the transition to a retail circular economy transition.
Casualty scheduling optimisation with facility disruptions under grey information in early stage of post-earthquake relief
Authors: Zhou Yufeng , Gong Ying , Hu Xiaoqing , Liu Changshi
Published: December 2022

Purpose

The purpose of this paper is to propose a new casualty scheduling optimisation problem and to effectively treat casualties in the early stage of post-earthquake relief.

Design/methodology/approach

Different from previous studies, some new characteristics of this stage are considered, such as the grey uncertainty information of casualty numbers, the injury deterioration and the facility disruption scenarios. Considering these new characteristics, we propose a novel casualty scheduling optimisation model based on grey chance-constrained programming (GCCP). The model is formulated as a 0–1 mixed-integer nonlinear programming (MINP) model. An improved particle swarm optimisation (PSO) algorithm embedded in a grey simulation technique is proposed to solve the model.

Findings

A case study of the Lushan earthquake in China is given to verify the effectiveness of the model and algorithm. The results show that (1) considering the facility disruption in advance can improve the system reliability, (2) the grey simulation technology is more suitable for dealing with the grey uncertain information with a wider fluctuation than the equal-weight whitening method and (3) the authors' proposed PSO is superior to the genetic algorithm and immune algorithm.

Research limitations/implications

The casualty scheduling problem in the emergency recovery stage of post-earthquake relief could be integrated with our study to further enhance the research value of this paper.

Practical implications

Considering the facility disruption in advance is beneficial to treat more patients. Considering the facility disruption in the design stage of the emergency logistics network can improve the reliability of the system.

Originality/value

(1) The authors propose a new casualty scheduling optimisation problem based on GCCP in the early stage of post-earthquake relief. The proposed problem considers many new characteristics in this stage. To the best of the authors' knowledge, the authors are the first to use the GCCP to study the casualty scheduling problem under the grey information. (2) A MINP model is established to formulate the proposed problem. (3) An improved integer-encoded particle swarm optimisation (PSO) algorithm embedded grey simulation technique is designed in this paper.
A dual-lattice hydrodynamic-thermal MRT-LBM model implemented on GPU for DNS calculations of turbulent thermal flows
Authors: Forslund T.O.M. , Larsson I.A.S. , Hellström J.G.I. , Lundström T.S.
Published: December 2022

Purpose

The purpose of this paper is to present a fast and bare bones implementation of a numerical method for quickly simulating turbulent thermal flows on GPUs. The work also validates earlier research showing that the lattice Boltzmann method (LBM) method is suitable for complex thermal flows.

Design/methodology/approach

A dual lattice hydrodynamic (D3Q27) thermal (D3Q7) multiple-relaxation time LBM model capable of thermal DNS calculations is implemented in CUDA.

Findings

The model has the same computational performance compared to earlier publications of similar LBM solvers. The solver is validated against three benchmark cases for turbulent thermal flow with available data and is shown to be in excellent agreement.

Originality/value

The combination of a D3Q27 and D3Q7 stencil for a multiple relaxation time -LBM has, to the authors’ knowledge, not been used for simulations of thermal flows. The code is made available in a public repository under a free license.
Labor misallocation and productivity growth in Vietnamese manufacturing firms
Authors: Nguyen Phuong Thi , Nguyen Hung Viet , Ha Hoa Quynh
Published: December 2022

Purpose

This research identifies the level of labor misallocation in Vietnamese manufacturing sector for the period 2005–2019. The paper also examines the effects of labor misallocation on productivity in Vietnamese manufacturing firms controlled by industry- and firm-level factors.

Design/methodology/approach

The level of labor misallocation and efficiency gains in total factor productivity (TFP) are assessed using Vietnam's annual enterprise survey data for the period 2005–2019 and Hsieh and Klenow (2009) productivity decomposition framework.

Findings

The results indicate four main points. Firstly, labor misallocation tends to increase from 2005 to 2019. Secondly, labor misallocation by firm ownership and technology level is found to be highest in state-owned enterprise and low-tech industries, whereas foreign direct investment and high-tech firms have lowest labor misallocation. Labor misallocation in small- and medium-sized enterprises is higher than in large-sized enterprises and is equivalent to overall sample. Thirdly, labor misallocation decreases productivity in manufacturing firms. The firm-level factors such as bigger technology gap, external capital, firm scale and poor liquidity ratio decrease productivity in manufacturing firms. Whereas firm-level factors such as Vietnam's accession to the WTO, reasonable corporate tax structure, capital intensity, human capital and firm age increase productivity of manufacturing firms. The industry-level factors such as FDI horizontal, forward and supply backward spillovers promote productivity from foreign firms to domestic ones. Meanwhile, only backward linkages reduce productivity of firms. Finally, by difference-in-differences (DID) method, the result indicates foreign firms have higher average labor productivity than domestic firms before or after Vietnam's accession to the WTO. After joining WTO, the average labor productivity of foreign firms is increased by 854 million VND while the average labor productivity of domestic firms is increased by 895 million VND. The DID between the two groups (domestic firms and foreign firms) before and after Vietnam's accession to WTO is 41 million dong.

Research limitations/implications

The main limitation of the study is that the market is assumed perfectly competitive. The model focuses on selective factors affecting labor productivity.

Originality/value

The focus of many previous international research papers was generally to look at the level of labor misallocation in developed countries. However, knowledge about labor misallocation is limited, particularly in the context of developing countries. This paper examines the level of labor misallocation by region, ownership, level of technology and firm size on productivity and the effect of misallocation on productivity in Vietnamese manufacturing firms.

Do family ties and structure matter for ethical and moral values?
Authors: James Jr Harvey S. , Giwa-Daramola Damilola
Published: December 2022

Purpose

This paper seeks to determine whether family ties and structure correlate with the ethical and moral values that are important underpinnings of economic activities.

Design/methodology/approach

The analysis uses data from the World Values Survey (WVS). Given the multilevel nature of the data in a cross-country setting, the paper utilizes a multilevel linear mixed-effects model with maximum likelihood estimation.

Findings

Families with strong ties and those with traditional family structures are less tolerant of unethical conduct and have more restrictive moral values than households where ties are weak and the household is not married. There also appears to be a bi-causal relationship in the data.

Originality/value

This paper considers a broad array of values in a cross-country setting and utilizes a multilevel modeling approach that has not been done in studies linking both family ties and structure.

A fully actuated aerial manipulator system for industrial contact inspection applications
Authors: Hao Shuang , Song Guangming , Mao Juzheng , Gu Yue , Song Aiguo
Published: December 2022

Purpose

This paper aims to present a fully actuated aerial manipulator (AM) with a robust motion/force hybrid controller for conducting contact-typed inspection tasks in industrial plants.

Design/methodology/approach

An AM is designed based on a hexarotor with tilted rotors and a rigidly attached end effector. By tilting the rotors, the position and attitude of the AM can be controlled independently, and the AM can actively exert forces on industrial facilities through the rigidly attached end effector. A motion/force hybrid controller is proposed to perform contact-typed inspection tasks. The contact-typed inspection task is divided into the approach phase and the contact phase. In the approach phase, the AM automatically approaches the contact surface. In the contact phase, a motion/force hybrid controller is used for contact-typed inspection. Finally, a disturbance observer (DOB) is used to estimate external disturbances and used as feedforward compensation.

Findings

The proposed AM can slowly approach the contact surface without significant impact in the contact phase. It can realize constant force control in the direction normal to the contact surface in the contact phase, whereas the motion of the remaining directions can be controlled by the operator. The use of the DOB ensures the robustness of the AM in the presence of external wind disturbances.

Originality/value

A fully actuated AM system with a robust motion/force hybrid controller is proposed. The effectiveness of the proposed AM system for conducting contact-typed industrial inspection tasks is validated by practical experiments.
Impact of additive manufacturing on maritime transportation: a review
Authors: Teweldebrhan Biniam Tekle , Maghelal Praveen , Galadari Abdulla
Published: December 2022

Purpose

Although additive manufacturing (AM; 3D printing/3DP) is presently in its infancy, once it becomes economically viable for mass production, it would revolutionize the operation and supply chain network of traditional businesses and manufacturing industries. To this end, approaches for ensuring a smooth transition of the economy, businesses, manufacturing centers and related services are being investigated. This review paper assesses the existing literature on the impact of AM on the maritime transportation sector.

Design/methodology/approach

This paper provides a systematic literature review through three methodological phases: (1) a comprehensive review of the number of English language literature studies published on the topics of AM or 3DP (1970–2021); (2) a bibliometric analysis of selected keyword combinations and (3) a detailed review on the impact of AM on different sectors.

Findings

The key findings are that existing studies do not attempt to forecast shipping volume and ton-miles that can be affected by the mainstreaming of the technology. Additionally, existing literature that focuses on the impact of the technology on different shipping categories is limited to studies on container ships.

Originality/value

The review identifies some potential areas of research that since maritime transportation will be affected by mainstreaming AM, it will have economic, social and environmental impacts on global trade that require future assessment.

Design/methodology/approach

To do that, the authors will review some of the results of preview risk assessments by selected countries, and based on that, the authors will discuss the Brazilian methodology and the achieved results.

Findings

The authors argue that this methodology can lead to better results than the most common ones and deliver outputs that are important to the development of countries’ anti-ML/TF.

Originality/value

To the best of the authors’ knowledge, this paper is the first to discuss the results and limitations of the current most widely used methodology for legal persons and arrangements money laundering risk assessment and to propose the use of a more efficient one.
Substitute vs permanent teacher job satisfaction: applying MUSA to delineate differences and highlight evidence-based guidelines for decision makers
Authors: Glaveli Niki , Manolitzas Panagiotis , Grigoroudis Evangelos
Published: December 2022

Purpose

The purpose of this paper is threefold. First, to explore the importance of specific work environment facets for the overall job satisfaction (JS) of primary full-time permanent teachers (PTs) and substitute/temporary teachers (STs). Second, to highlight the similarity or difference in JS patterns among PTs and STs. Third, to provide guidelines for effective evidence-based human resource management (HRM) interventions targeting to boost PTs and STs JS levels by considering: (1) the perceived importance of individual work facets for them and (2) the school's performance in providing a satisfactory work environment.

Design/methodology/approach

Data on overall and important JS facets (i.e. satisfaction with opportunities for self-fulfillment, work intensity/load, salary/income, leadership and collegial relations) were collected from a sample of 438 PTs and STs in Greece. Moreover, MUSA, a method that combines Multi-Criteria Decision (MCDA) and Importance-Performance Analysis (IPA), was applied to uncover the critical work environment facets of PTs and STs overall JS that call for interventions.

Findings

The findings suggest that PTs seem to value, more than STs, the transactional and economic aspects of the school environment. More precisely, on the part of PTs, self-fulfillment and salary/income are the main contributors to their JS, whilst leadership is the least important facet of JS. For STs self-fulfillment and collegial relationships are the aspects of work that contribute the most to their overall JS, whilst salary/income is the least important contributor. The study results further indicate that self-fulfillment is the strong attribute of Greek schools' work environment in boosting TJS regardless teachers' status, whilst salary/income and workload are potential threats.

Originality/value

It is one of the few studies that provide insights into the differing JS patterns of STs and PTs through the application of a MCDA/IPA method. Therefore, it offers evidence-based guidelines that take into consideration both the school's performance (overall and facet JS) and importance of core aspects of the work experience for STs and PTs.
A psychometric evaluation of the applicability of LibQUAL+® in a developing country perspective in Bangladesh
Authors: Ahmed S.M. Zabed , Shoeb Md. Zahid Hossain
Published: December 2022

Purpose

The purpose of this paper is to assess the psychometric validity of the LibQUAL+® instrument in a developing country context in Bangladesh.

Design/methodology/approach

This study adopted a paper-version of the original LibQUAL 22 core-items to survey library users' perceptions of minimum, desired and perceived levels of service quality of university libraries in Bangladesh. The survey accumulated a total of 544 valid responses over a period of two weeks. The means and standard deviations for each service item were computed for the three service levels. The confirmatory factor analysis (CFA) was used to test the original three-factorial structure and to assess the psychometric validity of the LibQUAL instrument. A one-factor CFA and separate CFAs by gender and user group on perceived services were conducted to determine the original three-factor structure of LibQUAL scale. Exploratory factor analyses (EFAs) were also performed on the perceived scores to examine the potential factor structure of the scale. The descriptive statistics including EFAs and the CFA models were performed through IBM® SPSS® Statistics and IBM® SPSS® Amos, respectively.

Findings

The findings of this paper showed that all perceived services fell below the minimum scores. The confirmatory factor analyses found poor model fits for the original three-factor solution of the LibQUAL scale. The EFA results also showed no factorial structure similar to the original LibQUAL dimensions. The findings exhibited a low psychometric quality of LibQUAL in academic library settings in Bangladesh.

Originality/value

This study is the first of its kind to empirically examine the psychometric validity of the LibQUAL scale in a developing country perspective in Bangladesh.
An interactive assessment framework for residential space layouts using pix2pix predictive model at the early-stage building design
Authors: Mostafavi Fatemeh , Tahsildoost Mohammad , Zomorodian Zahra Sadat , Shahrestani Seyed Shayan
Published: December 2022

Purpose

In this study, a novel framework based on deep learning models is presented to assess energy and environmental performance of a given building space layout, facilitating the decision-making process at the early-stage design.

Design/methodology/approach

A methodology using an image-based deep learning model called pix2pix is proposed to predict the overall daylight, energy and ventilation performance of a given residential building space layout. The proposed methodology is then evaluated by being applied to 300 sample apartment units in Tehran, Iran. Four pix2pix models were trained to predict illuminance, spatial daylight autonomy (sDA), primary energy intensity and ventilation maps. The simulation results were considered ground truth.

Findings

The results showed an average structural similarity index measure (SSIM) of 0.86 and 0.81 for the predicted illuminance and sDA maps, respectively, and an average score of 88% for the predicted primary energy intensity and ventilation representative maps, each of which is outputted within three seconds.

Originality/value

The proposed framework in this study helps upskilling the design professionals involved with the architecture, engineering and construction (AEC) industry through engaging artificial intelligence in human–computer interactions. The specific novelties of this research are: first, evaluating indoor environmental metrics (daylight and ventilation) alongside the energy performance of space layouts using pix2pix model, second, widening the assessment scope to a group of spaces forming an apartment layout at five different floors and third, incorporating the impact of building context on the intended objectives.
Differences in preferences for appreciation across various work settings
Authors: White Paul
Published: December 2022

Purpose

Previous research has documented the distribution of preferences of various appreciation languages by employees in general work settings. This paper aims to explore if employee preferences for appreciation vary across different types of workplace settings.

Design/methodology/approach

The Motivating By Appreciation Inventory assesses individuals’ preferred ways of receiving appreciation from their workplace colleagues, determining each person’s primary language of appreciation in one of four appreciation languages. Results for 114,827 individuals were examined across the general workforce and in six work settings (government agencies, medical settings, military personnel, nonprofit organizations, remote employees and schools).

Findings

Preferences within four work settings (government, nonprofits, remote, schools) were consistent with those from general work settings. But employees in medical settings and in the military choose Acts of Service more frequently than other employees. Quality Time is more valued by school and remote employees. Tangible Gifts are chosen at lower rates by government employees and military personnel.

Research limitations/implications

The subjects are all English-speaking and predominately in the USA. The results may not be generalizable to other cultures and language speakers.

Practical implications

Human resource professionals should be aware that employees in different types of workplaces vary in their appreciation preferences. Adjusting appreciation programs and practices should mirror these differences.

Originality/value

To the best of the author’s knowledge, this research is the first known to document differences in preferences for appreciation across various types of workplaces.
Politics and the sustainable development goals: Tourism Agenda 2030 perspective article
Authors: Hall Colin Michael , Seyfi Siamak , Koupaei Sara Naderi
Published: December 2022

Purpose

The 2030 Agenda provides the normative framework for much contemporary thinking on sustainable tourism. This viewpoint paper aims to discuss the inherently political nature of the sustainable development goals (SDGs) and the implications for tourism and sustainability.

Design/methodology/approach

This is a paper that highlights the political dimensions of positioning tourism within the SDGs.

Findings

This paper highlights continuing challenges in the broader politics of sustainable development in terms of the development of the 2030 Agenda and its implementation. It finds that the SDGs function as a form of metagovernance for sustainable development and sustainable tourism in particular.

Originality/value

This paper reinforces the importance of understanding the politics of the 2030 Agenda by locating sustainable tourism and the SDGs in the broader political context and the significance of metagovernance. In so doing, this paper contributes to continued theoretical debates on the framing of sustainable tourism that are key to understanding the politics of sustainable development and the winners and losers in the politics of tourism.
Immunoadsorption and plasmapheresis at the ICU – A description of the frequencies and indications in a single center experience and a case report
Authors: Koball Sebastian , Rogge Johannes , Frimmel Silvius , Hinz Michael , Mitzner Steffen
Published: December 2022

Immunologically mediated diseases can lead to severe courses that have to be treated in an intensive care unit. The use of extracorporeal organ support systems (ventilation, ECMO) is common. A therapeutic principle for these diseases is the removal of disease‐causing antibodies. This can be done nonspecifically by plasmapheresis or specifically by immune adsorption. While most intensive care units have the facilities for plasmapheresis (membrane plasma filtration), immunoadsorption is much less common. Over a period of 10 years, the numbers of immunoadsorption and plasmapheresis treatments performed in a single center intensive care unit are shown according to their indication (IA: 18 Pts, 58 treatments. PA: 54 Pts, 148 treatments). A case study of a patient with granulomatosis with polyangiitis shows the successful treatment with immunoadsorption. The advantages of immunoadsorption in patients with complex coagulation disorders and a critical clinical picture in terms of SIRS and ARDS are shown.
Regulating humanity's impact on the earth: The promise of transnational environmental law
Authors: Webster Emily
Published: December 2022

Transnational environmental law (TEL) is a relatively new field of research that is agitated by the concept of the Anthropocene. Like environmental law, TEL suffers from certain methodological challenges which are exacerbated by the sheer ammount of activity involved in the generation of transnational legal norms and regulation. This article argues that, despite some of these challenges, TEL is well placed to evolve further to better regulate human activity in the Anthropocene. It argues that to better reflect on what the Anthropocene means for TEL and how it may develop in practice, it must engage further with power, the problem of erasure of weaker actors, and the legacies of colonialism on the one hand, and the sciences – particularly Earth system science and ecology ‐ on the other. By doing so it would offer a more robust analysis of TEL and insights into its further development in practice.
Risk of accidents and unintentional injuries in men and women with attention deficit hyperactivity disorder across the adult lifespan
Authors: Libutzki Berit , Neukirch Benno , Kittel‐Schneider Sarah , Reif Andreas , Hartman Catharina A.
Published: December 2022

Introduction

Attention deficit hyperactivity disorder (ADHD) is associated with risk‐taking behavior, leading to accidents and unintentional injuries (summarized here as incidents). Main aim of this study is to determine if men and women with and without ADHD differ in the risk of mild (treated outpatient) and severe (treated inpatient) incidents across the adult lifespan (age groups: 18–29; 30–59, and ≥60 years). Secondary aim: investigate the role of comorbid mental disorders and drugs for the treatment of these comorbidities, and ADHD‐medication.

Methods

Using anonymized German claims data (N = 4,575,027), adults with ADHD diagnosis during 2016–2019 (N = 17,041) were compared with a 1:4 age and sex‐matched group without ADHD diagnosis. Regression analyses statistically tested group differences.

Results

Incidents occur in a U‐shaped form across the adult lifespan. Individuals with ADHD show the same pattern but at a substantially increased risk of both mild and severe incidents throughout the lifespan. Women without ADHD are at lower risk in young adulthood than men but at higher risk in older adulthood. Women with ADHD show the same pattern for severe incidents, but for mild incidents they have the highest risk throughout the lifespan. Co‐occurring anxiety disorder and the use of psycholeptics and ADHD‐medication decreased the incident risk.

Conclusion

We extend available knowledge which has hitherto focused on young adult males and traffic accidents. ADHD is associated with increased incidents across the adult lifespan, with distinct patterns regarding age, sex, and incident severity. An accurate diagnosis of ADHD in adulthood provides the first step towards prevention of accidents and unintentional injuries.
Benefits of protected area networks for breeding bird populations and communities
Authors: Sanderson F. J. , Wilson J. D. , Franks S. E. , Buchanan G. M.
Published: December 2022

Protected areas are a cornerstone of international conservation. The EU Natura 2000 network is the largest coordinated network of protected areas in the world, but its impact on biodiversity at the landscape scale is largely unknown. Here, we use data from Breeding Bird Survey (BBS) survey squares across Britain to test whether species abundance and population trends and levels of bird community specialisation are correlated with protected area coverage of BBS survey squares or 5‐km buffers around BBS squares. We compared area coverage by Natura 2000 protection and by the less strict protection of Sites of Special Scientific Interest protection alone. The abundance of birds of higher conservation concern and an index of community specialisation were positively correlated with coverage by protected area within survey squares and in a 5‐km buffer around squares. Population trends of species of higher conservation concern were positively correlated with the coverage of squares by Sites of Special Scientific Interest and the coverage of Natura 2000 within a 5‐km buffer around squares. The results suggest that Natura 2000 protection, in particular has positive conservation benefits for birds of higher conservation concern and community specialisation. This highlights the importance of protected areas, especially those with strictest protection, for maintaining biodiversity. Post‐Brexit, the UK should adopt legislation that results in the maintenance and strengthening of the current protected area network, as enforcing protection at a level of that provided by the Nature Directives is essential. As currently around half of Natura 2000 sites are not in favourable condition, even greater conservation benefits might be accrued if protected area management were improved.

Eurasian Grey and White wolf ancestors—800,000 years evolution, adaptation, pathologies and European dog origins
Authors: Diedrich Cajus G.
Published: December 2022

The oldest known wolf appears 800,000 years ago (Marine Isotope Stage 21) in Eurasia with the unspecialized short‐legged old Mammoth steppe wolfCanis lupus bohemicanov. spec. From this species, about 600,000–420,000 years ago (MIS 15‐11), the interglacialCanis lupus mosbachensis(Soergel, 1925) short‐legged Mosbach grey wolf subspecies roamed Eurasia. In the late Middle Pleistocene, there are two lineages, the southern interglacial grey and northern glacial White wolves in Eurasia. Since 320,000 (MIS 8), the short‐legged White wolfCanis lupus spelaeus(Goldfuss, 1823) was the glacial Mammoth steppe‐adapted wolf. Parallel to the “cave wolf” (found in the German Zoolithen Cave), the warm climate grey wolfCanis lupus brevisKuzmina and Sablin, 1994 existed.C.l.spelaeusrelates to the Holocene (MIS 1) extant Holarctic GreenlandCanis lupus arctosand SiberianCanis lupus albus(Kerr, 1792). The Late Palaeolithic (MIS 2) “Gravettian Goyet dogs” fall into the DNA pool ofC.l.spelaeusand are identified herein as pathological bite trauma individuals, which braincase shortened during the healing process. European prehistoric Neolithic dogs seem to have been imported from Central Asia with the Bandkeramik people (approx. 7000 BP) first, which have the stepped frontals originating from grey wolves.
Transforming the Quality Maternal Newborn Care Framework into an index to measure the quality of maternity care
Authors: Cummins Allison , Symon Andrew
Published: December 2022

Background

The Quality Maternal and Newborn Care (QMNC) Framework describes the care that childbearing women and newborn infants need in all settings. It comprises five components and was designed for use in planning, workforce development, and resource allocation, aimed at improving the quality and cost effectiveness of maternal and newborn care globally. The purpose of this paper is to describe the first phase of a project designed to transform the Framework into a quantitative tool for service user assessment of the quality of maternity care.

Methods

Each component of the original Framework content was developed into a draft service user questionnaire and distributed to an expert panel, drawn from a range of low‐, middle‐, and high‐resource countries. The panel consisted of five Framework authors, nine midwife researchers, six midwives, and five service user (consumer) advocates. Two rounds of discussion and revision were undertaken with the expert panel who commented on the importance, relevance and clarity of questions, and then on their necessity, wording, and order. A third round involved two experts in survey design.

Results

Following 24 responses in the first round, the questions were refined and returned to the panel. After incorporating the second‐round comments from 16 experts, the survey was then sent to two experts in questionnaire design and construction. Face validity was affirmed through this consultative process.

Conclusions

Despite Covid‐19 pandemic‐related restrictions, this robust iterative consultative process with an international expert panel has resulted in the prototype QMNC Framework index (QMNCFi)—a questionnaire designed for use in diverse settings to assess the quality of maternity care. The QMNCFi's psychometric properties are now being tested in an international online survey.
Do ridesharing services cause traffic congestion?
Authors: Pang Jindong , Shen Shulin
Published: December 2022

This paper uses a difference‐in‐differences strategy and an event‐study analysis to evaluate the effect of Uber entries on vehicle miles travelled in 346 US Metropolitan statistical areas between 2011 and 2017. Empirical results demonstrate that Uber entries have no significant effect on the total vehicle miles travelled in a city. However, Uber is found to decrease the vehicle miles travelled on highways but increase them on collector roads. All these effects come mainly from large metropolitan statistical areas.

Mitral aortic intervalvular fibrosa or aorto‐mitral curtain is a fibrous avascular skeletal structure located between the anterior leaflet of the mitral valve and the non‐coronary and left coronary cusps of the aortic valve. Mitral and aortic valve endocarditis are rarely accompanied by mitral aortic intervalvular fibrosa pseudoaneurysm and left atrial fistula of the aorta. Pseudoaneurysm of mitral aortic intervalvular fibrosa is a fatal complication that can occur after valvular surgery, valvular endocarditis, or blunt trauma. In this article, reconstructive surgical management with the Commando technique of a case who developed mitral‐aortic intervalvular fibrosa pseudoaneurysm to left atrial fistula after aortic and mitral prosthetic valve endocarditis is described. The important feature of this article is that it is a first in the literature as it is accompanied by persistent left superior vena cava.

Background

Intracranial dural arteriovenous fistulas (dAVFs) are pathological anastomoses between meningeal arteries and dural venous sinuses or cortical veins. Diagnosis of dAVFs can be challenging due to their broad range of clinical manifestations and the lack of specificity in their symptoms. We present a rare case of a patient with bilateral dAVFs, who was referred to our department for carotid doppler ultrasonography/transcranial color Doppler.

Case Report

A 67‐year‐old man was referred by his treating physician for neurovascular ultrasonography due to vision impairment associated with papilledema of both eyes. On ultrasound examination both external carotid arteries showed a “pseudo‐internalization” pattern with high end‐diastolic velocities and reduced resistance indices. Subsequent magnetic resonance and digital subtraction angiography revealed dAVF of both transverse sinuses, with occipital and medial meningeal arteries as feeders.

Conclusions

Neurovascular sonography may serve as a screening and follow‐up tool when a DAVF in the transverse sinus/sigmoid sinus is suspected.
Does skilled labor risk matter to suppliers? Evidence from trade credit
Authors: Khoo Joye , Cheung Adrian (Wai Kong)
Published: December 2022

Failure to attract and retain skilled labor exposes firms to skilled labor risk. This paper examines whether and how skilled labor risk affects trade credit offered by suppliers. The empirical analyses show that firms with greater exposure to skilled labor risk are associated with a reduction in trade credit granted by suppliers. It is consistent with the view that the risk arising from the departures of skilled employees is detrimental to firms. A change in employees who are well‐connected with the suppliers undermines firms’ bargaining power with their suppliers. Organization capital, managerial ability, and financial constraint are important moderators.
Atypical lipomatous tumour/well‐differentiated liposarcoma found in the buccal mucosa: A rare case report
Authors: Lee You‐Jung , Choi So‐Young
Published: December 2022

Oral liposarcomas are uncommon diseases, the most predominant histopathological subtype being atypical lipomatous tumour/well‐differentiated liposarcoma. In regard to its clinical aspects in the oral cavity, it is challenging to confirm a diagnosis and develop a treatment plan. In this case report, we present a rare case of atypical lipomatous tumour/well‐differentiated liposarcoma in the right cheek of a 77‐year‐old male patient. Conservative surgery was performed considering the histopathological subtype of the neoplasm. Knowledge of the clinical and histopathological characteristics of this rare disease is essential to maintaining function and aesthetics through conservative treatment in older patients.

Introduction

Current treatment for haemophilia A involves factor VIII replacement or non‐replacement (emicizumab) therapies, neither of which permanently normalise factor VIII levels. Gene therapy using adeno‐associated viral (AAV) vectors is an emerging long‐term treatment strategy for people with severe haemophilia A (PwSHA) that is likely to be available for clinical use in the near future.

Aim

This article proposes practical guidelines for the assessment, treatment, and follow‐up of potential PwSHA candidates for AAV‐based gene therapy.

Method

Using the Delphi method, a working group of Italian stakeholders with expertise in and knowledge of the care of adults with haemophilia A analysed literature for AAV‐based gene therapy and drafted a list of statements that were circulated to a panel of Italian peers. During two rounds of voting, panel members voted on their agreement with each statement to reach a consensus.

Results

The Delphi process yielded 40 statements regarding haemophilia A gene therapy, across five topics: (1) organisational model; (2) multidisciplinary team; (3) patient engagement; (4) laboratory surveillance; and (5) patient follow‐up and gene therapy outcomes. The consensus was reached for all 40 statements, with the second round of voting needed for five statements.

Conclusion

Use of the hub‐and‐spoke organisational model and multidisciplinary teams are expected to optimise patient selection for gene therapy, as well as the management of dosing and patient follow‐up, patient engagement, laboratory surveillance, and patient expectations regarding outcomes. This approach should allow the benefits of AAV‐based gene therapy for haemophilia A to be maximised.
Survey of recurrent diagnostic challenges in breast phyllodes tumours
Authors: Tan Benjamin Yongcheng , Fox Stephen B , Lakhani Sunil R , Tan Puay Hoon
Published: December 2022

Background

Breast phyllodes tumours (PTs) are graded as benign, borderline, or malignant by analysis of multiple histological features. PT grading is often inconsistent, likely due to variation in the weighting of grading criteria by pathologists.

Design

The hierarchy of use of diagnostic criteria was identified using a 20‐question survey.

Results

In all, 213 pathologists from 29 countries responded. 54% reported 10–50 PT cases per year. Criteria considered key to PT diagnosis were: increased stromal cellularity (84.3%), stromal overgrowth (76.6%), increased stromal mitoses (67.8%), stromal atypia (61.5%), stromal fronding (59.0%), periductal stromal condensation (58.0%), irregular tumour borders (46.3%), and/or lesional heterogeneity (33.7%). The importance of grading parameters were: mitotic activity (55.5%), stromal overgrowth (54.0%), stromal atypia (51.9%), increased stromal cellularity (41.7%), and nature of the tumour border (38.9%). 49% would diagnose malignant PT without a full array of adverse features. 89% used the term “cellular fibroepithelial lesion (FEL)” for difficult cases; 45% would diagnose an FEL with stromal fronding (but lacking other PT features) as fibroadenoma (FA), 35% FEL, and 17% PT. 59% deemed clinico‐radiological findings diagnostically significant; 68% considered age (≥40 years) important in determining if an FEL was a FA or PT. In FELs from young patients, increased stromal cellularity (83%), fronding (52%), and mitoses (41%) were more common. 34% regarded differentiating cellular FA from PT as a specific challenge; 54% had issues assigning a borderline PT grade.

Conclusion

Criteria for grading PT lie on a spectrum, leading to interpretive variability. The survey highlights the criteria most used by pathologists, which do not completely align with WHO recommendations.
Refining the Lorenz‐ranking of rules for claims problems on restricted domains

Published: December 2022

The comparison of the central rules for claims problems, according to the Lorenz order, has been studied not only on the entire set of problems but also on some restricted domains. We provide new characterizations of the adjusted proportional rule as being Lorenz‐maximal or Lorenz‐minimal within a class of rules on the half‐domains. Using this result, we rank the adjusted proportional, the minimal overlap, and the average‐of‐awards rules by analyzing whether or not these rules satisfy progressivity and regressivity on the half‐domains. We also find that the adjusted proportional rule violates two well‐known claim monotonicity properties.
Anti‐hypercholesteraemic and antioxidative activities of camel skin gelatin hydrolysate: effect of enzyme type, enzyme: substrate ratio and time of hydrolysis

Published: December 2022

Camel skin gelatin hydrolysate (CSGH) was prepared using different proteolytic enzymes [alcalase (A), protease (P) and their combination (AP (1:1))], hydrolysis time (2, 4 and 6 h) and enzyme: substrate (E/S) ratio (1%, 3% and 5%). In general, the degree of hydrolysis (DH) increased with increasing hydrolysis time for all enzyme treatments. CSGHs generated with alcalase showed significantly higher lipase (LP) inhibitory activity compared with protease‐derived CSGH at all hydrolysis conditions (P < 0.05). Whereas higher cholesterol esterase (CE) inhibitory activity was observed with CSGH produced by protease (P < 0.05). However, when CSGHs were produced using AP, the highest LP and CE inhibitory activity were recorded at 3 and 1% E/S ratio during 2 and 4 h of hydrolysis, respectively (P < 0.05). Antioxidant assays revealed that CSGHs showed improved radical scavenging activities compared with native CSG (P < 0.05). Overall results indicated that CSGHs with higher in vitro anti‐hypercholesteraemic and antioxidant activities could be obtained by enzymatic hydrolysis.
