Consumer perceptions of sustainability labels for alternative food networks
Authors: Teufer Birgit , Waiguny Martin K.J. , Grabner-Kräuter Sonja
Published: July 2023

Purpose

Sustainability labels play a crucial role in providing consumers with quick and easily accessible information to assess the environmental, social and economic impacts of products. This research examines how different sustainability labels influence consumer perceptions and assessments of alternative food networks (AFNs).

Design/methodology/approach

The authors conducted three cross-sectional studies to explore consumer perceptions of sustainability labels for AFNs. The authors tested labels representing the three sustainability dimensions, labels of different graphical quality and different awarding bodies.

Findings

Consumers did not differentiate between sustainability dimensions but assessed labels in a holistic manner. The overall rating of a label positively influenced perceived sustainability. Self-designed and professionally designed labels had a positive effect on the intention to buy from an AFN. Professionally designed labels also enhanced the perceived authenticity of the networks. Notably, the source of the label, whether self-awarded or awarded by an official body, did not significantly impact consumer perceptions. However, interaction effects revealed professionally designed labels had a stronger positive effect on purchase intention when they were self-awarded.

Practical implications

AFNs can derive benefits from using labels. Self-organized, non-profit AFNs are well advised to have labels professionally designed.

Originality/value

This research contributes to the understanding of the effects of sustainability labels for community-based AFNs, diverging from the traditional focus on individual products.
Critical risk factors for construction supply chain in China: a fuzzy synthetic evaluation analysis
Authors: Deng Binchao , Lv Xindong , Du Yaling , Li Xiaoyu , Yin Yilin
Published: July 2023

Purpose

Inefficiency dilemmas in project governance are caused by various risks arising from the characteristic of construction supply chain projects, such as poor project performance, conflicts between stakeholders and cost overrun. This research aims to establish a fuzzy synthetic evaluation (FSE) model to analyze construction supply chain risk factors. Corresponding risk mitigation strategies are provided to facilitate the improvement performance of ongoing construction supply chain projects.

Design/methodology/approach

A literature review is utilized to reveal the deficiencies of construction supply chain risk management. Thus, a total of five hundred (500) questionnaires are distributed to construction professionals, and four hundred and thirty-five (435) questionnaires are recovered to obtain the evaluation data of construction professionals on critical risk factors. Additionally, the FSE is used to analyze and rank the significance of critical risk factors. Finally, this research discusses nine critical risk factors with high weight in the model, and explains the reason for the significance of critical risk factors in the construction supply chain.

Findings

The questionnaire results show that the thirty-one (31) identified critical risk factors are verified by related practitioners (government departments, universities and research institutions, owners, construction units, financial institutions, design units, consulting firms). Thirty-one (31) identified critical risk factors are divided into common risks, risks from contractors and risks from owners. The most significant factors in the three categories, respectively, are “political risks,” “owner's unprofessional” approach and “cash flow.” Managing these risks can facilitate the development of the construction supply chain.

Originality/value

This paper expands the research perspective of construction supply chain risk management and complements the risks in the construction supply chain. For practitioners, the research result provides some corresponding measures to deal with these risks. For researchers, the research result provides the direction of construction supply chain risk treatment.
Developing a framework for higher education institution building maintenance via soft system methodology
Authors: Ebekozien Andrew , Aigbavboa Clinton , Samsurijan Mohamad Shaharudin , Rohayati Mohd Isa , Malek Nor Malina
Published: July 2023

Purpose

Inadequate strategic planning and maintenance budget may undermine the maintenance of the Higher Education Institution Building (HEIB). Studies have shown that a customised maintenance concept such as Soft System Methodology (SSM) can improve public building maintenance operations. There is a paucity of studies regarding public HEIB maintenance in Nigeria via an SSM approach. Therefore, the research investigated the state of public HEIB and developed a framework to improve public HEIB maintenance practices in Nigeria.

Design/methodology/approach

The research adopted SSM to understand Nigeria’s public HEIB maintenance practices. The SSM permitted a substitute approach to improve public HEIB maintenance practices via a developed framework. Data were collated via virtual interviews with experts, and findings were presented in line with the SSM seven steps.

Findings

Findings show that besides the shoddy state of public HEIB maintenance, there is no public digitalised HEIB framework to improve maintenance practices across Nigeria’s higher education institutions. The study developed a digitalised framework with the support of Computerised Maintenance Management System from the findings. It would reposition the public HEIB and stir up various agencies/departments/units managing maintenance for better service delivery via integrated delivery, practical, methodological and managerial aspects.

Originality/value

The research investigated Nigeria’s public HEIB maintenance practices via SSM to identify the required document and propose a feasible framework to improve Nigeria’s HEIB maintenance practices. Besides the developed conceptual framework, Nigeria’s HEIB maintenance practitioners and higher institution chief executives can use the recommended framework as guidelines to improve HEIB maintenance practices.
What does “sustainable supply chain management” really mean? A contribution to bridging the gap between research, education and practice
Authors: Fritz Morgane M.C. , Ruel Salomée
Published: July 2023

Purpose

This study explores practitioners' perspectives on and definitions of sustainable supply chain management (SSCM), which are then compared to academic definitions to identify new implications for researchers, educators and practitioners.

Design/methodology/approach

An abductive, explorative and qualitative approach was followed in the form of a review and classification of 31 academic definitions of SSCM as well as 30 interviews with supply chain (SC) practitioners.

Findings

The practitioners' answers show a lack of awareness of upstream and downstream challenges as the practitioners' focus on practices within the practitioners' firms, where the economic and environmental dimensions prevail. However, the practitioners highlighted understudied topics in SSCM: human resources policies, leadership for sustainability and ethics.

Research limitations/implications

This research stimulates discussion on how to teach an SSCM course and which directions to follow to ensure that research has an impact on practices. Practitioners' focus on the practitioners' everyday practices confirms that practice-based theories, amongst others, are relevant in the field and that more interdisciplinary research is needed to highlight the contributions of human resource management (HRM) and business ethics to SSCM.

Practical implications

The proposed framework clearly defines the scope of the practices and research (upstream or downstream of the SC or within the firm), which will allow practitioners to contribute to SSCM more holistically.

Social implications

Educators and researchers have a crucial role to play in clarifying the meaning of SSCM for students who are future practitioners and consumers. Interacting more with practitioners could help.

Originality/value

This research is targeted not only to researchers and practitioners but also educators.

Authors: Gupta Himani , Gupta Ayushi
Published: July 2023

Purpose

The devastating acute COVID-19 epidemic crippled the global economy in 2020. Within a month of the COVID-19 epidemic, every industry saw its stock prices plummet the most. Ending the COVID-19 pandemic will need equitable access to safe and effective vaccinations. This study aims to look at the link between COVID-19 vaccination and the stock markets for health and pharmaceutical sector.

Design/methodology/approach

The researchers used a mean-adjusted return model and event research approach to figure out how the first dose of the COVID-19 vaccine affects health and pharmaceutical sector stock market returns.

Findings

The evidence-based outcome indicates that immunisation announcement affects health and pharmaceutical company returns. Furthermore, the study concludes that the health and pharmaceutical industry is inefficient for a short period of time, but after 41 days, the sector absorbs the noisy information.

Originality/value

Since the outbreak, the development of COVID-19 vaccines has been a key focus of shareholders and investors. This study is unique in that it investigates the effect of the first dosage of SARS-CoV-2 vaccination on equity returns in the health and pharmaceutical industries, and it is likely to make a substantial contribution to the capital market literature on event methodology.
Effect of the sliding-rolling ratio on the force chain properties of granular flow lubrication interfaces
Authors: Cheng Pengfei
Published: July 2023

Purpose

To further understand the granular flow lubrication mechanism in metal contact pairs, the effect of sliding-rolling ratio on the force chain properties was investigated.

Design/methodology/approach

The parallel inter-plate model of the granular flow lubrication was established with discrete element method. Then, the correlation law between sliding-rolling ratio and force chain evolution properties was calculated and analyzed with PFC2D software platform.

Findings

Numerical calculation results show that the dynamic fluctuation property of force chain is existed, and the shock frequency of it is increased with the increase of sliding-rolling ratio. The same evolution law is also occurred for the bearing rate of strong force chain in the initial expansion and final compression phases, and the opposite phenomena is obtained for the overall expansion phase. Moreover, the directivity of strong force chain is changed by the sliding-rolling ratio. With the increase of sliding-rolling ratio, the directivity of strong force chain is first tended to y-axis, and then inclined to the x-axis in the whole phases. The basic reason is that a clamping up and downward movement impact for the neighbor particles are the essence of the above phenomenon.

Originality/value

The main contribution of this work is to lay a theory foundation of interfacial lubrication mechanism with granular flow.

Why is it so hard to provide a faithful representation? The impact of indirectly evoked incentives on the accounting policy decision and the accountant’s subsequent post-decision distortion
Authors: Maruszewska Ewa Wanda , Niesiobędzka Małgorzata , Kołodziej Sabina
Published: July 2023

Purpose

The study aims to investigate the impact of indirectly evoked incentives, in the form of supervisor’s preferences, on the decision about accounting policy regarding depreciation method selection and to examine subsequent post-decision distortion by evaluating the depreciation method.

Design/methodology/approach

The authors conducted two experiments with control and treatment groups, manipulating the supervisor’s indirectly evoked preferences. In Study 2, the authors also measured the evaluation of both depreciation methods to investigate post-decisional distortion regarding the assessment of the depreciation method chosen in a decision task. Study 1 was conducted among 85 accounting students, while Study 2 consisted of 200 accountants.

Findings

Both studies revealed the significant impact of supervisor’s indirectly evoked preferences on accounting policy decisions. Participants who were aware of supervisors’ preferences were more likely to choose the depreciation method that was consistent with those preferences. The authors also found that those participants attached a higher value to the depreciation method, providing evidence that adherence to the supervisor’s preferences results in a distorted assessment of the depreciation methods.

Originality/value

First, this study shows that indirectly evoked supervisors’ preferences may lead to a departure from substantive criteria resulting in low-quality accounting outcomes. Second, the assessment of the depreciation method is inseparable from the situational context, as the evaluation of the depreciation method is interdependent upon the preferences of the choice of a depreciation method and the fulfillment of those preferences.
Understanding health misinformation sharing among the middle-aged or above in China: roles of social media health information seeking, misperceptions and information processing predispositions
Authors: Tang Yulong , Luo Chen , Su Yan
Published: July 2023

Purpose

The ballooning health misinformation on social media raises grave concerns. Drawing upon the S-O-R (Stimulus-Organism-Response) model and the information processing literature, this study aims to explore (1) how social media health information seeking (S) affects health misinformation sharing intention (R) through the channel of health misperceptions (O) and (2) whether the mediation process would be contingent upon different information processing predispositions.

Design/methodology/approach

Data were collected from a survey comprising 388 respondents from the Chinese middle-aged or above group, one of China's most susceptible populations to health misinformation. Standard multiple linear regression models and the PROCESS Macro were adopted to examine the direct effect and the moderated mediation model.

Findings

Results bolstered the S-O-R-based mechanism, in which health misperceptions mediated social media health information seeking's effect on health misinformation sharing intention. As an indicator of analytical information processing, need for cognition (NFC) failed to moderate the mediation process. Contrarily, faith in intuition (FI), an indicator reflecting intuitive information processing, served as a significant moderator. The positive association between social media health information seeking and misperceptions was stronger among respondents with low FI.

Originality/value

This study sheds light on health misinformation sharing research by bridging health information seeking, information internalization and information sharing. Moreover, the authors extended the S-O-R model by integrating information processing predispositions, which differs this study from previous literature and advances the extant understanding of how information processing styles work in the face of online health misinformation. The particular age group and the Chinese context further inform context-specific implications regarding online health misinformation regulation.

Technology infiltration: permeable boundaries and work–life spillover experiences among academics in the United Kingdom during the COVID-19 pandemic
Authors: Mordi Chima , Ajonbadi Hakeem Adeniyi , Adekoya Olatunji David
Published: July 2023

Purpose

This study explored the challenges academics faced with work structures during the COVID-19 pandemic and their implications for their work–life balance (WLB).

Design/methodology/approach

Relying on the interpretative paradigm and the qualitative research method, the dataset consists of semi-structured interviews with 43 academics in the United Kingdom.

Findings

This study’s findings indicate that academics in the UK experience issues around increased boundary permeability between work and nonwork domains and role overlap, which engender the transfer of negative rather than positive spillover experiences and exacerbate negative consequences to the well-being of academics. ICTs also reinforced gendered work-family boundaries and generated more negative work–life/family spillover for women than for men.

Practical implications

Higher Education Institutions (HEIs) need to address ICT-related health issues through better work designs and HR initiatives that respond to the health requirements of academics. Policymakers should be futuristic and ensure comprehensive work–life policies for academics, which are necessary for humanising overall organisational well-being.

Originality/value

Although COVID-19 challenges are common to all workers, the experiences and effects on specific workers (in this case, UK academics) within specific national jurisdictions play out differentially, and they are often experienced with different levels of depth and intensity.

Authors: Yadav Vishwas , Kumar Vimal , Gahlot Pardeep , Mittal Ankesh , Kaswan Mahender Singh , Garza-Reyes Jose Arturo , Rathi Rajeev , Antony Jiju , Kumar Abhinav , Owad Ali Al
Published: July 2023

Purpose

The study aims to identify Green Lean Six Sigma (GLSS) barriers in the context of Higher Education Institutions (HEIs) and prioritize them for executing the GLSS approach.

Design/methodology/approach

A systematic literature review (SLR) was used to identify a total of 14 barriers, which were then verified for greater relevance by the professional judgments of industrial personnel. Moreover, many removal measures strategies are also recommended in this study. Furthermore, this work also utilizes Gray Relational Analysis (GRA) to prioritize the identified GLSS barriers.

Findings

The study reveals that training and education, continuous assessment of SDG, organizational culture, resources and skills to facilitate implementation, and assessment of satisfaction and welfare of the employee are the most significant barriers to implementing this approach.

Research limitations/implications

The present study provides an impetus for practitioners and managers to embrace the GLSS strategy through a wide-ranging understanding and exploring these barriers. In this case, the outcomes of this research, and in particular the GRA technique presented by this work, can be used by managers and professionals to rank the GLSS barriers and take appropriate action to eliminate them.

Practical implications

The ranking of GLSS barriers gives top officials of HEIs a very clear view to effectively and efficiently implementing GLSS initiatives. The outcomes also show training and education, sustainable development goals and organizational culture as critical barriers. The findings of this study provide an impetus for managers, policymakers and consultants to embrace the GLSS strategy through a wide-ranging understanding and exploring these barriers.

Social implications

The GLSS barriers in HEIs may significantly affect the society. HEIs can lessen their environmental effect by using GLSS practices, which can support sustainability initiatives and foster social responsibility. Taking steps to reduce environmental effect can benefit society as a whole. GLSS techniques in HEIs can also result in increased operational effectiveness and cost savings, which can free up resources to be employed in other areas, like boosting student services and improving educational programs. However, failing to implement GLSS procedures in HEIs could have societal repercussions as well. As a result, it is critical for HEIs to identify and remove GLSS barriers in order to advance sustainability, social responsibility and operational effectiveness.

Originality/value

GLSS is a comprehensive methodology that facilitates the optimum utilization of resources, reduces waste and provides the pathway for sustainable development so, the novelty of this study stands in the inclusion of its barriers and HEIs to prioritize them for effective implementation.
Ecological impacts of invasive ecosystem engineers: A global perspective across terrestrial and aquatic systems
Authors: Rilov Gil , Canning‐Clode João , Guy‐Haim Tamar
Published: July 2023

In both terrestrial and aquatic ecosystems, invasive species are a major driver of global change that is increasing in scope and impact due to the increase in global trade, habitat modification and climate change. Among invasive species, those that are known as ‘ecosystem engineers’ are considered a specific, highly influential, type of invaders, where an invader significantly alters the new environment, either physically or chemically. In this context, this perspective review discusses the different types of possible impacts of invasive ecosystems engineers (IEE) in terrestrial, freshwater, and marine ecosystems.

Scanning the relevant literature on the topic, we find a 12‐year lag in the use of terms relevant to the concept of ecosystem engineers in invasion‐related publications since the first publication of the concept in 1994, with a steep increase in use between 2006 and 2014. A bibliometric mapping showed a high level of connectedness between related terms and clusters, suggesting an ample flow of concepts, ideas and knowledge between realms, ecosystems and regions, and researchers that study them.

Throughout this essay, we illustrate with recent examples the context‐dependency of their (positive and negative) impacts in the three realms. We review the distinction between autogenic (altering the environment for other species with their body) and allogenic (altering the environment for other species with their actions) ecosystem engineering in the context of alien species. We also put a spotlight on the well‐studied engineering effects of IEE plants and macroalgae, terrestrial and aquatic bioturbators and burrowers as well as highly effective consumers.

We finalize with discussing how IEE can strongly affect ecosystem services for human wellbeing and explore the possible contribution of IEE in restoring functions and services in the face of climate change in highly invaded and fast‐warming systems like the southeastern Mediterranean Sea or areas that face frequent fires for example. We claim that the last topic has received little attention from the scientific community and should be given priority in future studies.

Exposure pathways matter: Aquatic phototrophic communities respond differently to agricultural run‐off exposed via sediment or water
Authors: Polst Bastian H. , Allen Joey , Hölker Franz , Hilt Sabine , Stibor Herwig , Gross Elisabeth M. , Schmitt‐Jansen Mechthild
Published: July 2023

Small shallow ponds are widespread but understudied water bodies in agricultural landscapes. Agricultural run‐off (ARO) transports pesticides and nutrients into adjacent aquatic ecosystems where they occur dissolved in the water column or are bound to sediments. Consequently, aquatic communities are affected by ARO via different exposure pathways. We hypothesize that sediment‐bound ARO mainly affects submerged rooted macrophytes, while phytoplankton and periphyton are more prone to ARO in water. These primary producers compete for resources resulting in a regime shift between alternative stable states of macrophyte or phytoplankton dominance. We hypothesize that warming increases nutrient release from sediments and thereby facilitates the occurrence of phytoplankton dominance.

Using a full‐factorial microcosm design, we exposed aquatic primary producers to either sediment or water application of a mixture of common pesticides (terbuthylazine, pirimicarb, tebuconazole and copper) and nitrate at two concentrations and two temperatures (22°C and 26°C) for 4 weeks. Initial and final concentrations of pesticides and nitrate, final biomass of macrophytes, periphyton and phytoplankton, pesticide accumulation in macrophytes and changes in carbon, nitrogen and phosphorus content and selected exoenzyme activities in the sediment were measured.

We found lower final macrophyte biomass for both ARO treatments compared to controls, indicating a prevalence of negative effects by herbicides and competition for light with other phototrophs. In contrast, phytoplankton and periphyton biomass increased, but only when exposed to ARO via the water column, indicating a prevalence of positive effects by nutrient supply. Microbial carbon and nutrient cycling in sediments was not affected by ARO. Higher temperature mitigated ARO‐related effects on macrophytes under sediment exposure.

Synthesis and application. ARO poses a strong risk of submerged macrophyte loss and establishment of turbid conditions with phytoplankton dominance in aquatic ecosystems. In conclusion, exposure pathways as well as indirect and interacting effects of multiple stressors need to be considered when designing appropriate mitigation measures. Under climate change, we suggest to prioritize local measures as buffer strips a reduced use of pesticides and fertilizers, and sediment removal as appropriate measures to protect these vulnerable but widespread aquatic systems, which are highly relevant for biodiversity in agricultural landscapes.
Financial openness, financial sector development, and income inequality: With an extensive set of pull and push factors
Authors: Ashenafi Biruk Birhanu , Dong Yan
Published: July 2023

This paper investigates the impact of financial openness on financial sector development and income inequality. We use the de jure and de facto measures of financial openness across 78 countries from 1980 to 2019. By employing a system generalized method of moments (GMM) with 5‐year averaged data and a novel push and pull modeling framework, we obtain three key results. First, the de jure measure of financial openness exacerbates income inequality and is sensitive to banking crises and conflict intensity. Second, the de facto measure spurs stock value traded in emerging market economies (EMEs) and declines domestic credit in Africa. Third, the interaction between de facto measures with schooling and governance factors affects financial sector development and income inequality. We highlighted that the mere usage of the de jure measure and their interaction is incorrect. The key implication is that valuable information about the real impact of openness can be obtained from the de facto measures and their interaction with favorable macroeconomic fundamentals, governance factors, and adverse nonpolicy factors.
Changing Nature of Patents in Australia
Authors: Bakhtiari Sasan
Published: July 2023

Recent decades have seen substantial changes to the innovation systems of major economies, not least due to a paradigm shift caused by the digital revolution. Whether smaller advanced economies such as Australia have undergone a similar shift or moved to fill the void left by other countries is unclear. This issue is important as it sets the long‐term growth path of these economies. I use Australian patent data and show that there has been a similar surge in Australia in patenting, mainly driven by medical and digital technologies. Australia, however, is showing more strength in a few niche areas. At the same time, the scope of patents, as one measure of basicness, narrowed over the years. This has been driven by private companies opting for applied research and also refocusing their innovation efforts away from chemical and material technologies and onto digital technologies and other applied areas.
Reciprocity in Corporate Tax Compliance—Evidence from Ozone Pollution
Authors: CHOW TRAVIS , FAN ZHONGWEN , HUANG LI , LI OLIVER ZHEN , LI SIMAN
Published: July 2023

In a tax—public goods reciprocity framework between citizens and the state, managers view taxes as a payment to the government in exchange for public goods, and hence they adjust their willingness to pay taxes as public good quality changes. We show that corporate tax planning intensity increases with ground‐level ozone pollution. Revisions in ozone pollution regulations cause counties that failed the revised and more stringent standards to reduce ozone pollution. Consequently, firms headquartered in these counties reduced corporate tax planning intensity relative to firms in other counties. The ozone‐tax link varies in the predicted directions with public attention to pollution, potential welfare loss due to ozone, managers’ stakeholder orientation, taxpayers’ polluting status, political preferences, and civic norms. We also find consistent results for Superfund cleanups of hazardous waste sites. Our research sheds light on reciprocity as a potential mechanism influencing corporate tax compliance.
C‐reactive protein as an early predictor of anastomotic dehiscence in various types of reconstruction in elective abdominal surgery
Authors: Scepanovic Milena , Randjelovic Tomislav , Karamarkovic Aleksandar , Cuk Vladimir , Stanojevic Goran , Kovacevic Bojan
Published: July 2023

Objective

The most important factor in abdominal surgery is the successful healing of the intestinal anastomosis performed. This study aims to evaluate the role of C‐reactive protein (CRP) in predicting anastomotic dehiscence in the first week following surgery.

Methods

The study included 100 patients surgically treated over a period of 1 year. Postoperative (p/o) values of CRP, leukocyte (white blood cells [WBCs]) and body temperature (BT) were measured in relation to the development of p/o complications.

Results

CRP p/o values were significantly higher in patients with complications and proved helpful in predicting p/o complications, while WBC and BT were not. For the development of anastomotic leakage, receiver operating characteristic curve shows the earliest diagnostic accuracy on the third p/o day with the cut‐off value of 115.1 mg/L; however, the largest area under the curve was on the fifth p/o day with a cut‐off value of 59.2 mg/L, a sensitivity of 89%, a specificity of 61%, a positive predictive value (PPV) of 21.9 and a negative predictive value (NPV) of 100.

Conclusions

Measurement of p/o CRP values may indicate problematic healing of digestive tract anastomosis before the appearance of clinical signs. High sensitivity and high NPV allow us to rule out p/o complications and anastomotic dehiscence with great certainty and safely discharge these patients from the hospital.
Revolutionary possibilities of love in a time of disaster, decolonisation, and diffraction
Authors: Mouat Clare M.
Published: July 2023

Representations of love appear across many disciplines and discursive fields that are and should be in conversation with geography. It is imperative that geographers engage in formidable but worthy tasks to distil diverse renderings of love into the regenerative interventions we urgently need. Those interventions require geographically minded interpretations of love to drive radical research, pedagogies, policies, and practices in ways that have direct and indirect effects across the life course and life worlds. Such labours are mediated by state and law, by intersectional relations, or by neuroscience, and involve asking how love underwrites critical infrastructures—of place (making), care and entanglements, colonialism, and human‐nature relations in the Anthropocene and posthuman—that lead to the flourishing futures we seek. Rich geographical studies oriented to those tasks still face charges of flattening difference. This commentary picks up one aspect of this agenda: a blind spot in geographical research relating to the ethical imperative to love based on benevolence. Instead, I champion the revolutionary possibilities for geography to inform policies, pedagogies, and practices by using a love based on alterity aligned with social weight, reasserting accessible science as an effective driver of social and system transformative changes. Specifically, I argue for a regenerative socio‐political analytic of love in a time of disaster, decolonisation, and diffraction.
The core genome evolution of Lactobacillus crispatus as a driving force for niche competition in the human vaginal tract

Published: July 2023

The lower female reproductive tract is notoriously dominated by Lactobacillus species, among which Lactobacillus crispatus emerges for its protective and health‐promoting activities. Although previous comparative genome analyses highlighted genetic and phenotypic diversity within the L. crispatus species, most studies have focused on the presence/absence of accessory genes. Here, we investigated the variation at the single nucleotide level within protein‐encoding genes shared across a human‐derived L. crispatus strain selection, which includes 200 currently available human‐derived L. crispatus genomes as well as 41 chromosome sequences of such taxon that have been decoded in the framework of this study. Such data clearly pointed out the presence of intra‐species micro‐diversities that could have evolutionary significance contributing to phenotypical diversification by affecting protein domains. Specifically, two single nucleotide variations in the type II pullulanase gene sequence led to specific amino acid substitutions, possibly explaining the substantial differences in the growth performances and competition abilities observed in a multi‐strain bioreactor culture simulating the vaginal environment. Accordingly, L. crispatus strains display different growth performances, suggesting that the colonisation and stable persistence in the female reproductive tract between the members of this taxon is highly variable.
Delayed formation of neural representations of space in aged mice
Authors: McDermott Kelsey D. , Frechou M. Agustina , Jordan Jake T. , Martin Sunaina S. , Gonçalves J. Tiago
Published: July 2023

Aging is associated with cognitive deficits, with spatial memory being very susceptible to decline. The hippocampal dentate gyrus (DG) is important for processing spatial information in the brain and is particularly vulnerable to aging, yet its sparse activity has led to difficulties in assessing changes in this area. Using in vivo two‐photon calcium imaging, we compared DG neuronal activity and representations of space in young and aged mice walking on an unfamiliar treadmill. We found that calcium activity was significantly higher and less tuned to location in aged mice, resulting in decreased spatial information encoded in the DG. However, with repeated exposure to the same treadmill, both spatial tuning and information levels in aged mice became similar to young mice, while activity remained elevated. Our results show that spatial representations of novel environments are impaired in the aged hippocampus and gradually improve with increased familiarity. Moreover, while the aged DG is hyperexcitable, this does not disrupt neural representations of familiar environments.
“Say something in your language”: Lived experiences of Asian Americans during the COVID‐19 pandemic
Authors: Karandikar Sharvari , Munshi Additti , Cho Hyunyi
Published: July 2023

This paper explores anecdotes about and experiences of implicit and explicit acts of racism experienced by 16 Asian Americans living in the United States, who narrate stories about incidents of race‐based verbal, physical, or emotional violence. In addition, the participants detail hardships and experiences before COVID‐19, at the onset of COVID‐19, and most importantly, during the COVID‐19 pandemic. The results of the study build on the growing literature on the experiences of racism, othering, and invisibility among Asian communities. Further research is needed to capture the diversity of experiences of the Asian American communities and to identify interventions and practices that will best support their needs.
The Role of Early Trauma in the Formation of Belief in Reptilian Conspiracy Theories: A Psychoanalytic Perspective
Authors: Dixon Agnieszka M.
Published: July 2023

This paper investigates whether conspiracy theories arising during the COVID‐19 pandemic are linked to early trauma or a specific organization of the mind. Using the Reptilian conspiracy theory as an example, the paper proposes that belief in conspiracy theories can activate unresolved memories of trauma and serve as a mediator between the psyche and intrusive content. Classic psychoanalytic concepts, as well as more modern ideas from Britton and Steiner, are explored to understand the role of early trauma and inner object relations dynamics in the development of Belief in Reptilian Conspiracy Theories (BiCT). The concept of après‐coup is introduced to explain how newer responses to familiar psychic experiences may shape beliefs in conspiracies. Additionally, the paper proposes that belief in conspiracy theories can function as a psychic retreat. Two clinical cases are presented to illustrate these ideas while maintaining anonymity.

Published: July 2023

This study aimed to compare fetal myocardial performance index (MPI) between fetuses of pregnant women with gestational diabetes mellitus (GDM) and healthy controls and to evaluate the relationship between MPI and maternal glucose levels. This was a prospective study of 90 pregnant women, including 50 pregnancies with GDM (27 pregnancies with insulin‐regulated GDM and 23 pregnancies with diet‐regulated GDM) and 40 healthy controls. Isovolumetric contraction time (ICT) + isovolumetric relaxation time (IRT)/ejection time (ET) were used to calculate the MPI (MPI = [ICT + IRT]/ET). Fetal MPI, PR interval, E/A ratio, maternal plasma glucose levels on the day of MPI measurement, and neonatal outcomes were compared. The fetal left‐MPI was significantly higher in the GDM group than healthy controls (0.43 ± 0.04 vs. 0.40 ± 0.06, p = 0.007). The best cut‐off level for MPI was >0.41 to predict adverse perinatal outcomes (sensitivity: 70%, specificity: 68%, area under the curve: 0.715, 95% confidence interval: 0.5143–0.8205, p < 0.001). The fetal MPI values showed no correlation with maternal plasma fasting, postprandial glucose, and hemoglobin A1c (HbA1c) levels. Reduced E/A ratio, higher neonatal intensive care unit admissions, and the need for cesarean delivery were detected in the GDM group. Fetal MPI is impaired in women with GDM, and the need for insulin therapy is associated with higher MPI values and adverse neonatal outcomes. Fetal MPI can help detect fetuses with potential adverse outcome risks, owing to impaired fetal cardiac function.

Precomputed Radiance Transfer (PRT) remains an attractive solution for real‐time rendering of complex light transport effects such as glossy global illumination. After precomputation, we can relight the scene with new environment maps while changing viewpoint in real‐time. However, practical PRT methods are usually limited to low‐frequency spherical harmonic lighting. All‐frequency techniques using wavelets are promising but have so far had little practical impact. The curse of dimensionality and much higher data requirements have typically limited them to relighting with fixed view or only direct lighting with triple product integrals. In this paper, we demonstrate a hybrid neural‐wavelet PRT solution to high‐frequency indirect illumination, including glossy reflection, for relighting with changing view. Specifically, we seek to represent the light transport function in the Haar wavelet basis. For global illumination, we learn the wavelet transport using a small multi‐layer perceptron (MLP) applied to a feature field as a function of spatial location and wavelet index, with reflected direction and material parameters being other MLP inputs. We optimize/learn the feature field (compactly represented by a tensor decomposition) and MLP parameters from multiple images of the scene under different lighting and viewing conditions. We demonstrate real‐time (512 x 512 at 24 FPS, 800 x 600 at 13 FPS) precomputed rendering of challenging scenes involving view‐dependent reflections and even caustics.

Image stylization has seen significant advancement and widespread interest over the years, leading to the development of a multitude of techniques. Extending these stylization techniques, such as Neural Style Transfer (NST), to videos is often achieved by applying them on a per‐frame basis. However, per‐frame stylization usually lacks temporal consistency, expressed by undesirable flickering artifacts. Most of the existing approaches for enforcing temporal consistency suffer from one or more of the following drawbacks: They (1) are only suitable for a limited range of techniques, (2) do not support online processing as they require the complete video as input, (3) cannot provide consistency for the task of stylization, or (4) do not provide interactive consistency control. Domain‐agnostic techniques for temporal consistency aim to eradicate flickering completely but typically disregard aesthetic aspects. For stylization tasks, however, consistency control is an essential requirement as a certain amount of flickering adds to the artistic look and feel. Moreover, making this control interactive is paramount from a usability perspective. To achieve the above requirements, we propose an approach that stylizes video streams in real‐time at full HD resolutions while providing interactive consistency control. We develop a lite optical‐flow network that operates at 80 Frames per second (FPS) on desktop systems with sufficient accuracy. Further, we employ an adaptive combination of local and global consistency features and enable interactive selection between them. Objective and subjective evaluations demonstrate that our method is superior to state‐of‐the‐art video consistency approaches. maxreimann.github.io/stream‐consistency
LoCoPalettes: Local Control for Palette‐based Image Editing

Palette‐based image editing takes advantage of the fact that color palettes are intuitive abstractions of images. They allow users to make global edits to an image by adjusting a small set of colors. Many algorithms have been proposed to compute color palettes and corresponding mixing weights. However, in many cases, especially in complex scenes, a single global palette may not adequately represent all potential objects of interest. Edits made using a single palette cannot be localized to specific semantic regions. We introduce an adaptive solution to the usability problem based on optimizing RGB palette colors to achieve arbitrary image‐space constraints and automatically splitting the image into semantic sub‐regions with more representative local palettes when the constraints cannot be satisfied. Our algorithm automatically decomposes a given image into a semantic hierarchy of soft segments. Difficult‐to‐achieve edits become straightforward with our method. Our results show the flexibility, control, and generality of our method.

Objectives

The primary aim of this in vitro study was to assess the effect of alveolar residual bone height in the posterior maxilla on the accuracy of the final implant position via free‐handed and static Computer‐Assisted Implant Placement (sCAIP). The secondary aim was to evaluate the influence of the maxillary sinus morphology on the accuracy of final implant position.

Materials and Methods

Partially edentulous standardized maxillary models simulating three different residual bone heights and different sinus floor morphologies were investigated. One‐hundred eighty equally distributed implants, which were placed either free‐handed or sCAIP, constituted the study sample. 3D digital deviations were obtained by superimposing the post‐surgical scans on the initial treatment plan.

Results

Angular and linear deviation assessment demonstrated higher implant position accuracy in the sCAIP group. sCAIP revealed similar outcomes independently of the alveolar bone height and sinus floor morphology. Contrarily, in the free‐handed group, alveolar bone height and sinus morphology statistically affected the final implant position. Non‐parametric three‐way ANOVA showed significance for implant placement protocol (p < .0001) and alveolar bone height (p ≤ .02) when angular, and linear deviations were evaluated. Sinus morphology was statistically significantly associated with angular deviation (p = .0009).

Conclusions

sCAIP demonstrated higher 3D implant position accuracy. Alveolar bone height (strongly) and sinus morphology are associated with the accuracy of final implant position when the free‐handed implant protocol is followed. However, these anatomical factors did not affect final implant position during sCAIP.
