Objective:

To identify risk factors associated with progression of pancreatic cysts in patients undergoing surveillance.

Summary Background Data:

Previous studies of intraductal papillary mucinous neoplasms (IPMNs) rely on surgical series to determine malignancy risk and have inconsistently identified characteristics associated with IPMN progression.

Methods:

We conducted a retrospective review of 2197 patients presenting with imaging concerning for IPMN from 2010-2019 at a single institution. Cyst progression was defined as resection or pancreatic cancer development.

Results:

Median follow-up time was 84 months from presentation. The median age was 66 years, and 62% were female. Ten percent had a first-degree relative with pancreatic cancer, and 3.2% had a germline mutation or genetic syndrome associated with increased risk of PDAC. Cumulative incidence of progression was 17.8% and 20.0% at 12- and 60-months post-presentation, respectively. Surgical pathology for 417 resected cases showed non-invasive IPMN in 39% of cases and PDAC with or without associated IPMN in 20%. Only 18 patients developed PDAC after 6 months of surveillance (0.8%). On multivariable analysis, symptomatic disease (hazard ratio [HR] 1.58 [95% CI 1.25–2.01]), current smoker status (HR 1.58 [95% CI 1.16–2.15]), cyst size (HR 1.26 [95% CI 1.20–1.33]), main duct dilation (HR 3.17 [95% CI 2.44–4.11]), and solid components (HR 1.89 [95% CI 1.34–2.66]) were associated with progression.

Conclusions:

Worrisome features on imaging at presentation, current smoker status, and symptomatic presentation are associated with IPMN progression. Most patients progressed within the first year of presentation to MSKCC. Further investigation is necessary to develop personalized cyst surveillance strategies.
Analysis of convergence of linkage and association studies in autism spectrum disorders
Authors: Mpoulimari Ioanna , Zintzaras Elias
Published: May 2023

Autism spectrum disorder (ASD) is a clinically and genetically heterogeneous group of pervasive neurodevelopmental disorders with a strong hereditary component. Although genome-wide linkage studies (GWLS) and [genome-wide association studies (GWAS)] have previously identified hundreds of ASD risk gene loci, the results remain inconclusive. In this study, a genomic convergence approach of GWAS and GWLS for ASD was implemented for the first time in order to identify genomic loci supported by both methods. A database with 32 GWLS and five GWAS for ASD was created. Convergence was quantified as the proportion of significant GWAS markers located within linked regions. Convergence was not found to be significantly higher than expected by chance (z-test = 1,177, P = 0,239). Although convergence is supportive of genuine effects, the lack of agreement between GWLS and GWAS is also indicative that these studies are designed to answer different questions and are not equally well suited for deciphering the genetics of complex traits.
Draft genomes, phylogenomic reconstruction and comparative genome analysis of three Xenorhabdus strains isolated from soil-dwelling nematodes in Kenya
Authors: Awori Ryan Musumba , Waturu Charles N. , Pidot Sacha J. , Amugune Nelson O. , Bode Helge B.
Published: May 2023

As a proven source of potent and selective antimicrobials,

Xenorhabdus

bacteria are important to an age plagued with difficult-to-treat microbial infections. Yet, only 27 species have been described to date. In this study, a novel

Xenorhabdus

species was discovered through genomic studies on three isolates from Kenyan soils. Soils in Western Kenya were surveyed for steinernematids and Steinernema isolates VH1 and BG5 were recovered from red volcanic loam soils from cultivated land in Vihiga and clay soils from riverine land in Bungoma respectively. From the two nematode isolates,

Xenorhabdus

sp. BG5 and

Xenorhabdus

sp. VH1 were isolated. The genomes of these two, plus that of

X. griffiniae

XN45 – this was previously isolated from Steinernema sp. scarpo that also originated from Kenyan soils – were sequenced and assembled. Nascent genome assemblies of the three isolates were of good quality with over 70 % of their proteome having known functions. These three isolates formed the

X. griffiniae

clade in a phylogenomic reconstruction of the genus. Their species were delineated using three overall genome relatedness indices: an unnamed species of the genus,

Xenorhabdus

sp. BG5,

X. griffiniae

VH1 and

X. griffiniae

XN45. A pangenome analysis of this clade revealed that over 70 % of species-specific genes encoded unknown functions. Transposases were linked to genomic islands in

Xenorhabdus

sp. BG5. Thus, overall genome-related indices sufficiently delineated species of two new

Xenorhabdus

isolates from Kenya, both of which were closely related to

X. griffiniae

. The functions encoded by most species-specific genes in the

X. griffiniae

clade remain unknown.
Contrasting the open access dissemination of COVID-19 and SDG research
Authors: Larivière Vincent , Basson Isabel , Clark Jocalyn P.
Published: May 2023

This paper examines the extent to which research has been published open access in response to two global threats: COVID-19 and the Sustainable Development Goals (SDGs), including climate change. We compare the accessibility of COVID-19 content versus SDG literature using the Dimensions database between 2000 and 2021, classifying each publication as gold open access, green, bronze, hybrid, or closed. We found that 79.9% of COVID-19 research papers published between January 2020 and December 2021 was open access, with 39.0% published with gold open access licenses. In contrast, just 55.7% of SDG papers were open access in the same time period, with only 36.0% published with gold open access licenses. Papers related to the climate emergency overall had the second-lowest level of open access at just 55.5%. Papers published by the largest for-profit publishers that committed to both the SDG Publishers Compact and climate actions were not predominantly published open access. The paper highlights the need for continued efforts to promote open access publishing to facilitate scientific research and technological development to address global challenges.

One-Sentence Summary

In contrast to COVID-19 papers, research on UN Sustainable Development Goals including the climate emergency have not been made open access by leading global science publishers despite their corporate commitments to sustainability and climate action.

Authors: Costa Caroline dos Santos , dos Santos Francine Silva , Gabe Kamila Tiemann , Steele Eurídice Martinez , Leite Fernanda Helena Marrocos , Khandpur Neha , Rauber Fernanda , Louzada Maria Laura da Costa , Levy Renata Bertazzi , Monteiro Carlos Augusto
Published: May 2023

Background and objectives

The consumption of unprocessed or minimally processed whole plant foods and of ultra-processed foods, as defined by the Nova food classification system, are associated in opposite ways with diet quality and risk of diseases. However, it can be difficult to evaluate and monitor the consumption of these foods in some contexts due to lack of resources and time constraints for data collection. This study aimed to describe two simple and easily derived diet quality scores and evaluate their performance in reflecting the dietary share of unprocessed or minimally processed whole plant foods and ultra-processed foods.

Methods

A total of 812 adults (18 years old or older) answered the Nova24h screener, a 2-minute self-administered questionnaire that measures the consumption of a set of foods on the day before the interview. Food items included in this tool belong to two main groups of Nova classification: unprocessed or minimally processed whole plant foods (WPF, 33 food items) and ultra-processed foods (UPF, 23 food items). Two scores are obtained from this tool by summing the number of items checked - the Nova-WPF and the Nova-UPF. We compared the Nova-WPF and the Nova-UPF scores with the dietary intake (% of total energy) of all unprocessed or minimally processed whole plant foods and all ultra-processed foods, respectively, obtained through a full self-administered web-based 24-hour recall, applied on the same day. We evaluated the relationship between the approximate quintiles or intervals of each score and the corresponding % of energy intake by linear regression, and the agreement between the intervals of each score with the intervals of the corresponding % of energy intake, using the Prevalence-Adjusted and Bias-Adjusted Kappa (PABAK).

Results

Approximate quintiles of each score presented a direct and linear relationship with the corresponding % of energy intake (p-value for linear trend <0.001). We found a substantial agreement between the intervals of each score and of the corresponding % of energy intake (PABAK 0.72, 95% CI 0.64-0.81 for the Nova-WPF score and PABAK 0.79, 95% CI 0.69-0.88, for the Nova-UPF score).

Conclusions

These two scores performed well against the dietary share of unprocessed or minimally processed whole plant foods and ultra-processed foods in Brazil and can thus be used to evaluate and monitor diet quality.
Unsupervised contrastive peak caller for ATAC-seq
Authors: Vu Ha T.H. , Zhang Yudi , Tuteja Geetu , Dorman Karin S.
Published: May 2023

The assay for transposase-accessible chromatin with sequencing (ATAC-seq) is a common assay to identify chromatin accessible regions by using a Tn5 transposase that can access, cut, and ligate adapters to DNA fragments for subsequent amplification and sequencing. These sequenced regions are quantified and tested for enrichment in a process referred to as “peak calling.” Most unsupervised peak calling methods are based on simple statistical models and suffer from elevated false positive rates. Newly developed supervised deep learning methods can be successful, but they rely on high quality labeled data for training, which can be difficult to obtain. Moreover, though biological replicates are recognized to be important, there are no established approaches for using replicates in the deep learning tools, and the approaches available for traditional methods either cannot be applied to ATAC-seq, where control samples may be unavailable, or are post hoc and do not capitalize on potentially complex, but reproducible signal in the read enrichment data. Here, we propose a novel peak caller that uses unsupervised contrastive learning to extract shared signals from multiple replicates. Raw coverage data are encoded to obtain low-dimensional embeddings and optimized to minimize a contrastive loss over biological replicates. These embeddings are passed to another contrastive loss for learning and predicting peaks and decoded to denoised data under an autoencoder loss. We compared our replicative contrastive learner (RCL) method with other existing methods on ATAC-seq data, using annotations from ChromHMM genomic labels and transcription factor ChIP-seq as noisy truth. RCL consistently achieved the best performance.
The impact of COVID-19 on parents of autistic children with a particular focus on access to respite care
Authors: Cooke Emma , Brenner Maria , Smith Valerie
Published: May 2023

Purpose

This study aims to explore how the COVID-19 pandemic has impacted parents of autistic children and their families in Ireland.

Design/methodology/approach

A qualitative thematic analysis methodology was applied using semi-structured interviews. A total of 12 parents (ten mothers, one father and one grandfather speaking on behalf of a mother) of autistic children were asked how the COVID-19 pandemic impacted them and their autistic child with a particular focus on how it has impacted their access to respite care. Interviews were completed remotely from July 2021 to October 2021.

Findings

Data analysis identified four themes that reflect an adverse pandemic impact. These were: world gone; alone and isolated; constantly fighting for help; and negative and positive impact of COVID-19 on child and family. Two parents reported positive outcomes of the pandemic such as social distance requirements. Five parents (42%) reported an increase in the amount of respite received. Three parents (25%) reported a decrease and four (33%) parents reported no change in their access to respite.

Research limitations/implications

COVID-19 has turned a spotlight on mental health for politicians, policymakers and the public and provides an opportunity to make mental health a higher public health priority for autistic children and their families.

Originality/value

This study highlights the need for access to respite for autistic children and for respite services to be responsive to the ongoing needs, in particular, the mental health needs of autistic children and their family, particularly in a crisis situation.
The perceived value of oat milk and the food-choice motives of young, urban people
Authors: Halme Merja , Pirttilä-Backman Anna-Maija , Pham Trang
Published: May 2023

Purpose

Both governments and the food industry are interested in plant-based products. New products are advertised as climate-friendly, with plant-based materials increasingly replacing animal-based content. In Finland, oat milk dominates the plant-based milk market. The authors studied what features young and urban users of plant-based and cow's milk value in oat milk for coffee and how the preferences of the users relate to ethical food-choice motives.

Design/methodology/approach

In total, 308 students filled in an e-questionnaire. The survey used best-worst scaling (BWS), a discrete choice approach, to measure the perceived values related to oat milk characteristics. The ethical motives were measured by a version of the Lindeman and Väänänen scale. Also the respondents' diets were asked. Preference clusters were identified and viewed with the ethical food-choice motives and diets.

Findings

The respondent group that exclusively used cow's milk attached more value to taste, added nutritional elements, discounts and recommendations by friends. The rest of the respondents attached more value to origin and sustainability-related features of oat milk. In the six-cluster solution, one extreme cluster was valuing taste and the other was valuing sustainability-related issues. All the ethical food-choice motives: ecological welfare, political values and religion were (roughly) the higher the cluster valued sustainability-related items. The respondents eating meat were more likely to belong to the clusters valuing taste than non-meat eaters that belong more likely to clusters valuing sustainability-related features.

Originality/value

Very few earlier studies have explored the heterogeneity of valuations of plant-based products and the products' relationship with ethical food-choice motives.
Marketing organic products: challenges and opportunities for a sustainable living
Authors: Attri Rekha , Bairagi Rahul
Published: May 2023

Learning outcomes

After reading and discussing the case, the participants would be able to:▪ articulate the challenges associated with retailing of organic products.▪ suggest paid, owned and earned digital marketing tools to Manav Chetna Vikas Kendra (MCVK);▪ suggest a digital marketing budget;▪ discuss essential elements of a good website design; and▪ discuss various website analytics metrics.

Case overview/synopsis

This case describes the challenges faced by the founder, Ajay Dayama, and members of MCVK, who believed in the concept of sustainable community living through the production and marketing of organic food products. They believed that they would be able to share their philosophy of sustainable living through their products reaching out to a larger population rather than just being consumed by community members. This paved the way for the creation of a brand by the name SATT offering products under the lifestyle, nutriment and wellness categories. Marketing and sales of SATT products came with a bundle of challenges, and it was not easy to convince customers about the authenticity, quality and pricing of these products. Many organic products sold by competitors were available on e-commerce platforms, while SATT relied on direct marketing. Low customer acceptance for SATT products would weaken the sustainability dream of the community. How MCVK could increase awareness and acceptance of SATT products was a big area of concern for Ajay.

Complexity academic level

This case is suitable for students enrolled for full credit course on Digital Marketing at postgraduate level. The case can be discussed towards the middle of the course.

Public trust in government doctors and hospitals in India
Authors: Panda Sitakanta
Published: May 2023

Purpose

The author studies the determinants of public trust in government doctors and hospitals (DH) – a crucial indicator of the quality of a country's healthcare system – in India by analyzing the India Human Development Survey (IHDS) 2011–2012.

Design/methodology/approach

The author uses descriptive statistics and a set of ordered probit regression models controlling for a set of individual-specific, household-level and other covariates and analyze across heterogeneous contexts (national/rural/urban/male heads/female heads/social groups).

Findings

Across contexts, people reporting a great deal of trust in private DH (PDH) are significantly more likely to report a great deal of trust in government DH. Those people with a great deal of trust in government schools to provide good education (vis-à-vis people with only some trust in government school) have significantly higher likelihood of reporting a great deal of trust in government DH. Visiting a private doctor last time (vis-à-vis a government doctor) makes reporting higher trust levels in government DH less likely.

Practical implications

India's healthcare system is afflicted with several resource allocation problems and low public trust issues are indicative of misgovernance. In presence of limited state capacity, ubiquitous corruption and underwhelming institutional trust, understanding the factors influencing public trust in healthcare providers is critical to designing appropriate trust-enhancing public health policies.

Originality/value

Given the sparse empirical literature on public trust in healthcare systems in the developing countries such as India, this study is a pertinent contribution as the study explains the determinants of public trust in DH using a comprehensive unit-recorded household survey dataset.
Disentangling the relationship between omnichannel integration and customer trust: a response surface analysis
Authors: Li Yang , Fang Jie , Yuan Shuai , Cai Zhao
Published: May 2023

Purpose

This study aims to examine whether customer trust is influenced by the congruence and incongruence between customers' perceptions of two types of omnichannel integration—perceived transactional integration (PTI) and perceived relational integration (PRI). The authors further considered the perceived effectiveness of e-commerce institutional mechanisms (PEEIM) as the boundary condition of omnichannel integration's effect.

Design/methodology/approach

Drawing upon the stereotype content model, this study hypothesizes the influences of PTI and PRI on customer trust wherein PEEIM moderates the relationships. The research model was empirically examined based on the responses surface analysis of survey data collected from 311 omnichannel customers.

Findings

Results showed that when PTI and PRI are congruent, customers are inclined to trust brands that have high levels of PTI and PRI rather than low levels of PTI and PRI. Moreover, the incongruence between PTI and PRI is positively related to customer trust. PEEIM was found to weaken the congruence effect while strengthening the incongruence effect. The authors also examined customer distrust as another relational outcome to provide a robust check.

Originality/value

This study uncovers customer cognition of omnichannel integration and examines the influences on customer trust, therefore contributing to our understanding of omnichannel integration's effect from the customer perspective. Findings from this research provide insights for brand managers on deploying channel integration strategies and institutional mechanisms to manage customer trust.
Revisiting the relationship between idiosyncratic risk and stock returns: a quantile regression analysis in the context of an emerging market
Authors: Ullah Saif , Jabeen Mehwish , Farooq Muhammad , Hamayun Asad Afzal
Published: May 2023

Purpose

The relationship between idiosyncratic risk and stock return has been debated for decades; this study reexamined this relationship in the Pakistani stock market by using the quantile regression approach along with the prospect theory.

Design/methodology/approach

The present study is quantitative, and secondary data obtained from an emerging market are used. The quantile regression method allows the estimates of idiosyncratic risk to vary across the entire distribution of stock returns, i.e. the dependent variable. In this study, the standard deviation of regression residuals from the Fama and French three-factor model was used to measure idiosyncratic risk. Convenience sampling is employed; the sample consists of 82 firms listed on the KSE-100 index, with 820 annual observations for the ten years from 2011 to 2020. After computing results by using quantile regression, the study's findings, ordinary least squares (OLS) and least sum of absolute deviation (LAD) regression techniques are also compared.

Findings

The quantile regression estimation results indicate that idiosyncratic risk is positively correlated with stock returns and that this relationship is contingent on whether prices are rising or falling. Consistent with the prospect theory, the finding suggests that stock investors tend to avoid risk when they anticipate a loss but are more willing to take risks when they anticipate a profit. The results of the OLS and LAD regressions indicate that the method typically employed in previous studies does not adequately describe the relationship between idiosyncratic risk and stock return at extreme points or across the entire distribution of stock return.

Originality/value

These empirical findings shed new light on the relationship between idiosyncratic risk and stock return in Pakistani stock market literature.
How do business educators prepare students better about ethical decision-making?
Authors: Do Hau Thi Kim
Published: May 2023

Purpose

This paper aims to identify predictors that affect business student perceptions on ethical decision-making. This paper also investigates how those predictors impact the decision-making related to ethical matters among Vietnamese business students.

Design/methodology/approach

A survey was conducted to collect data for testing the hypotheses. Questionnaires were administered to 500 Vietnamese business students from four public and private universities. The independent t-test was applied to the usable sample to analyze and derive relationships.

Findings

The empirical results showed that idealism and relativism significantly predict the perception of ethical decision-making. Idealism and relativism were found to influence high ethical decision-making significantly.

Originality/value

The study contributes to the literature on ethical decision-making in a transitional economy. New findings and insights from the research serve as a foundation for future research with ethics and decision-making topics. The results offer some insights to business schools in improving their ethical teaching courses and to businesses in their recruitment.
Talent management and performance in the public sector: the mediating role of line managerial support
Authors: Semaihi Saeed Obaid , Ahmad Syed Zamberi , Khalid Khalizani
Published: May 2023

Purpose

This study investigates the relationship between talent management and individual work performance in public sector organizations and evaluates the influence of line managerial support on mediating the link between talent management and individual work performance.

Design/methodology/approach

Data were collected from 128 respondents working in public sector organizations in the United Arab Emirates. SPSS was used to perform multiple regression analysis to analyze direct relationships between talent management and line managerial support on individual work performance. Using PROCESS mediation analysis, this study also investigates the mediating effects of line managerial support.

Findings

The present study reveals that line managerial support insignificantly influence the individual work performance. Moreover, the findings indicate a substitution effect between talent management and line managerial support, suggesting that public sector organizations may spend their money on relieving line managers of their responsibilities for talent development so that they may focus on other duties.

Practical implications

More dynamic perspectives on TM in the public sector are necessary to understand better how the TM agenda changes in response to changes in the strategic trajectories of public sector organizations and the interconnection between TM and performance in the public sector.

Originality/value

This study contributes to talent management research in the public sector domain of developing nations by emphasizing the crucial role of line managers in applying TM practices.
The dark side of leadership: abusive supervision and its effects on Employee's behavior and well-being
Authors: Santos Célia , Coelho Arnaldo , Filipe Ana , Marques Alzira Maria Ascensão
Published: May 2023

Purpose

The aim of this study is to examine the impact of abusive supervision on employees' emotional and work-related outcomes, using a theoretical framework that integrates affective events theory (AET) and self-determination theory (SDT). The research sought to explore the effects of abusive supervision on subordinates' positive and negative affect, and the subsequent impact on customer orientation and life satisfaction.

Design/methodology/approach

The data for this study were collected cross-sectionally through a structured questionnaire completed by employees who have experienced abusive supervision in their current or previous jobs. Structural equation modeling (SEM) was used to analyze the data.

Findings

The results indicated that when subordinates experienced abusive supervision, they reported lower levels of positive affect and higher levels of negative affect. These emotions, in turn, impacted their customer orientation and life satisfaction. Positive affect was found to positively influence both customer orientation and life satisfaction, while negative affect had a negative effect on life satisfaction. Surprisingly, customer orientation was positively impacted by negative affect.

Originality/value

Therefore, the findings of this study suggest that positive and negative affects mediate the relationship between abusive supervision and life satisfaction, but not with customer orientation. This study advances prior research by linking the impact of an abusive supervisor to employees' customer behavior and life satisfaction, using positive and negative affects as mediators, and building upon the theories of AET and SDT.
Knowledge, attitudes and experiences of menopause among “early” and “on-time” women
Authors: Córdoba Iñesta Ana Isabel , Ortí Notari Pilar , Gfellner Barbara M.
Published: May 2023

Purpose

Attitudes, experiences and knowledge about menopause are relevant, especially when menopause starts earlier than expected. This study aims to examine women who underwent this transition “early” and “on-time” according to these factors.

Design/methodology/approach

The sample included 117 women, 69 with “on-time” and 48 with premature menopause. Participants completed three questionnaires.

Findings

Women with premature menopause had a better understanding of it but more negative attitudes and a higher incidence of physical and psychological symptoms, although they indicated greater feelings of control over their symptoms. Moreover, “early” menopause women appeared to exhibit greater anxiety.

Practical implications

Results underscore the need to inform women about menopause as a natural developmental process.

Originality/value

This paper shows the menopause as a difficult transition especially for women with early menopause.
On-campus accommodation service quality: the mediating role of students' satisfaction on word of mouth
Authors: Gabbianelli Linda , Pencarelli Tonino
Published: May 2023

Purpose

Based on the main studies presented in the literature, this work aims to examine the level of student satisfaction towards the on-campus accommodation service provided by an Italian university. Notably, the objectives of the study are twofold: (1) to examine the mediating role of student satisfaction on the relationship between university on-campus accommodation service quality and word-of-mouth and (2) to determine whether there is any significant difference in students' satisfaction towards on-campus accommodation in terms of gender and the halls of residence.

Design/methodology/approach

The study is based on the results of a survey carried out through an online questionnaire by 381 students living on campus at the University of Urbino.

Findings

The findings revealed that the quality perceived by university students in relation to individual services had a positive impact on their general satisfaction towards the halls of residence experience.

Research limitations/implications

The study presents some limitations such as lack of temporal comparisons, a focus on specific service quality items and the fact that it refers to a single Italian university.

Practical implications

The findings of this study will help the management of public universities to improve the quality of services in their halls of residence for the satisfaction of their students.

Originality/value

To the authors' knowledge, there have been no previous studies about on-campus accommodation service quality conducted in Italy. The study contributes to enrich the service quality literature, confirming both that the sum of the quality of individual elements is not as the overall satisfaction and the outcome intention of positive WOM depends not only on service quality attributes, but also from an overall evaluation of satisfaction.
Public services in island sub‐districts: Towards geography‐based governance
Authors: Madubun Jusuf
Published: May 2023

This study proposes a form of governance of sub‐district public services based on the geography of the Maluku archipelago in Indonesia. Using qualitative research, data were collected using in‐depth interviews, focus group discussions, documentation, and field observations, involving informants from local and sub‐district government elements and community leaders. This study revealed that the governance of public services in the islands is not optimal because it cannot meet the challenges that are unique to the islands, such as minimal authority, inadequate organisation and management capacity of the sub‐district, lack of human resources and facilities support, and limited transportation facilities. This study found two primary causal factors, namely: first, internal factors, (1) implementation of the concept of symmetrical decentralisation in various local contexts, (2) disproportionate fiscal policies, and (3) weak political commitment of mayors regarding delegation of authority and discretion. Second, external factors are related to the difficulty of accessing services.

Points for practitioners

The non‐optimal governance of public services in the islands cannot meet the challenges.

The uniqueness of the islands includes minimal authority, inadequate organisation and management (O&M) capacity of the sub‐district, lack of human resources and facilities support, and limited transportation facilities.

The Islands Sub‐District Governance Model (ISGov‐Model) proposes attributive and discretionary authority, increased O&M capacity, financial support, and adequate staff and facilities.

The ISGov‐Model leads the archipelagic sub‐district to become the epicentre of public services.
Hydrothermal Systems Characterized by Crustal Thermally‐dominated Structures of Southeastern China
Authors: WANG Guiling , GAN Haonan , LIN Wenjing , YUE Gaofan , YAN Xiaoxue , LI Tingxin , ZHANG Wei , MA Feng
Published: May 2023

Southeastern China (SE China) is located in the Pacific tectonic domain and has experienced a series of tectonomagmatic events induced by the subduction of the Paleo‐Pacific Plate since the late Mesozoic. The subduction formed a series of NE‐NNE oriented faults under a NW–SE regional stress field, along which a number of thermal springs occur. Previous studies have focused on the genesis mechanism of specific geothermal fields in SE China, but the general characteristics of hydrothermal systems in SE China remains unclear. In this study, we investigate the correlation between geothermal activity, hydrochemical type and regional faults by studying the distribution of hydrothermal activity and geochemical properties of typical hydrothermal systems in SE China. The hydrothermal systems in SE China have a crustal thermally‐dominated structural origin unique to the specific geological and tectonic conditions of the Eurasian Plate margin. The upwelling of the asthenosphere and the widespread granitoids with high radiogenic heat production in SE China provide major heat sources for regional geothermal anomalies. The NE‐oriented crustal thermally‐dominated faults are critical for the formation of geothermal anomalies and NW‐oriented extensional faults have created favorable conditions for meteoric water infiltration, transportation and the formation of thermal springs.
An Early Paleozoic Ultramafic Complex in the North Wulan Metamorphic Complex, North Qaidam: Contraints on the Nature of the Alaskan‐type Continental Arc Root
Authors: SHAN Jinming , NIU Manlan , LI Xiucai , LI Chen , WANG Lei , ZHANG Shuai
Published: May 2023

Orogenic peridotite is an important component of orogenic belts and retains crucial information on mantle magmatic activity, slab subduction, and melt or fluid metasomatism. To determine the source of the mantle‐derived parental magma of the peridotite and to investigate the metasomatism that it experienced, we undertook an integrated study of the petrography, whole‐rock major‐ and trace‐element compositions, in situ zircon U‐Pb geochronology, and mineral major‐and trace‐element compositions of an early Paleozoic ultramafic complex in the North Wulan area of North Qaidam. The Halihatu ultramafic–mafic complex is composed of dunite, pyroxene peridotite, and gabbro, which are characteristic of Alaskan‐type complexes. The dunite yields a weighted mean 206Pb/238U age of 479 ± 5 Ma (MSWD = 0.7), which reflects the age of the metasomatism rather than the crystallization age of the ultramafic magma. The peridotites have high Mg# (89.8–91.8) and Cr contents (2419–5190 ppm), low Al2O3 (0.20–1.68 wt%) and Ni (289–1012 ppm) contents, and high olivine Fo contents (87–91), suggesting a large degree (∼15%–22%) of partial melting of lithospheric ultramafic rocks followed by variable degrees of fractional crystallization of olivine and pyroxene. This is consistent with estimates of 15%–22.3% partial melting calculated using the Cr# of spinel crystals and with the low Yb (0.04–0.33 ppm) and Y (0.72–1.29 ppm) contents of clinopyroxene crystals. Whole‐rock trace‐element patterns show enrichment in large ion lithophile elements and depletion in high field strength elements, along with high Al2O3 (2.10–6.47 wt%) and low TiO2 (0.01–0.21 wt%) contents of clinopyroxene crystals, suggesting an arc magma cumulate trend. These features, along with the high olivine Fo contents (87–91 ppm), imply that the Halihatu peridotite is an Alaskan‐type crustal cumulates derived from Mg‐rich hydrous basaltic melts. The high estimated fO2 (FMQ +1.97 to FMQ +3.81) further supports the idea that they formed in an arc setting. The Ni/Co and Ni/Mn ratios and cumulate textures of the olivine, quenched boundaries between mafic and felsic melts, and the occurrence of tremolite and phlogopite reflect interactions between the Halihatu peridotite and injected silicate and carbonatitic melts in the lower crust. Therefore, we propose a new cumulate‐infiltration model for the petrogenesis of Alaskan‐type ultramafic complexes, which improves our understanding of the nature of Alaskan‐type continental arc root.

Mask‐wearing, social distancing, and vaccination remain effective ways to mitigate the spread of COVID‐19. Yet, many hesitate to enact some or all these preventive behaviors. We created three persuasive messages—framed to promote benefits to either (1) oneself, (2) close‐others, or (3) distant‐others—to determine whether the effectiveness of these messages varied based on personality differences (specifically independent/interdependent self‐construal and chronic construal level). In two online experiments (N = 862), we measured individual differences and showed participants one of the three messages. Consistent interactions between interdependent self‐construal and message conditions showed that those high in interdependent self‐construal responded most positively to the self‐focused messages promoting mask‐wearing, social distancing, and COVID‐19 vaccination. Those low in interdependent self‐construal responded most negatively to the self‐focused messages. Although no interaction effect was observed for independent self‐construal, and inconsistent evidence emerged for construal level, other‐focused messages performed either better or equally well to the self‐focused messages for most participants and may thus be promising for future public health communication efforts.
Happy thoughts: The role of communion in accepting and sharing (mis)beliefs

The negativity bias favours the cultural diffusion of negative beliefs, yet many common (mis)beliefs—naturopathy works, there's a heaven—are positive. Why? People might share ‘happy thoughts’—beliefs that might make others happy—to display their kindness. Five experiments conducted among Japanese and English‐speaking participants (N = 2412) show that: (i) people higher on communion are more likely to believe and share happier beliefs, by contrast with people higher in competence and dominance; (ii) when they want to appear nice and kind, rather than competent and dominant, people avoid sharing sad beliefs, and instead prefer sharing happy beliefs; (iii) sharing happier beliefs instead of sad beliefs leads to being perceived as nicer and kinder; and (iv) sharing happy beliefs instead of sad beliefs fleads to being perceived as less dominant. Happy beliefs could spread, despite a general negativity bias, because they allow their senders to signal kindness.

Objective

To assess topographic concordance between the histopathological features of patients’ radical prostatectomy (RP) specimens and the location of the prostate‐specific membrane antigen positron emission tomography (PSMA PET) local recurrences, qualitatively and quantitatively.

Patients and Methods

Our cohort was selected from the 100 men who received a 18F‐DCFPyL PET scan in the IMPPORT trial (Australian New Zealand Clinical Trials Registry Number: ACTRN12618001530213), a prospective non‐randomised study completed by GenesisCare Victoria. Eligibility included patients with a rising prostate‐specific antigen (PSA) level (>0.2 ng/mL) after RP and PSMA PET detected local recurrence. Histopathological parameters collated included the location of tumour, extraprostatic extension (EPE), and positive margins. Criteria for the location and ‘concordance’ between histopathological features and local recurrences were pre‐defined.

Results

A total of 24 patients were eligible; the median age was 71 years, the median PSA level was 0.37 ng/mL, and the time between RP and PSMA PET was 2.6 years. In all, 15 patients had recurrences within the vesicourethral anastomotic region and nine within the lateral surgical margins. There was 100% concordance in the left–right plane between tumour location and local recurrence, with 79% of these lesions concordant three‐dimensionally; across craniocaudal, left–right, and anterior–posterior planes. In all, 10 of the 16 (63%) patients with EPE and five of the nine patients with positive margins had three‐dimensional concordance between their pathology and their local recurrence. In quantitative assessment, 17 of the 24 patients, had local recurrences that correlated with the location of their original tumour in the craniocaudal plane.

Conclusion

Local recurrence is highly concordant with the position of the tumour within the prostate. Predicting the location of local recurrence using the location of the EPE and positive margins is less helpful. Further investigation into this field, could impact surgical technique and salvage radiotherapy clinical target volume.
Dynamiques hydrogéomorphologiques historiques et actuelles d'une rivière perturbée par les activités de la drave et analyse des impacts d'un démantèlement de barrage
Authors: Bouchard Marianne , Boivin Maxime
Published: May 2023

Au Québec, la dynamique fluviale de la rivière des Escoumins a été perturbée par l'industrie forestière pendant plus d'un siècle. Un barrage a notamment été construit près de l'embouchure en 1846, puis démantelé en 2013. Ces perturbations ont entraîné des répercussions importantes sur l'équilibre du cours d'eau et sur l'habitat du saumon atlantique. Cette étude propose donc de caractériser la dynamique fluviale de la rivière des Escoumins et d'analyser les impacts du démantèlement du barrage dans une perspective de restauration des processus hydrogéomorphologiques et d'amélioration de l'habitat du saumon atlantique. Les résultats suggèrent que la trajectoire de la rivière a évolué différemment en fonction du style fluvial et de la composition granulométrique de chacun de ses segments homogènes. Toutefois, ce sont les activités de la drave et le démantèlement du barrage qui semblent avoir été les facteurs de contrôle les plus importants sur l'évolution de la trajectoire du cours d'eau. Le démantèlement a notamment permis la restauration de processus hydrogéomorphologiques et la libre circulation des salmonidés. Une meilleure procédure entourant le démantèlement des barrages et leur suivi devrait donc être mise en place au Canada afin de favoriser cette pratique.
Getting the bugs out of AI: Advancing ecological research on arthropods through computer vision

Deep learning for computer vision has shown promising results in the field of entomology, however, there still remains untapped potential. Deep learning performance is enabled primarily by large quantities of annotated data which, outside of rare circumstances, are limited in ecological studies. Currently, to utilize deep learning systems, ecologists undergo extensive data collection efforts, or limit their problem to niche tasks. These solutions do not scale to region agnostic models. However, there are solutions that employ data augmentation, simulators, generative models, and self‐supervised learning that can supplement limited labelled data. Here, we highlight the success of deep learning for computer vision within entomology, discuss data collection efforts, provide methodologies for optimizing learning from limited annotations, and conclude with practical guidelines for how to achieve a foundation model for entomology capable of accessible automated ecological monitoring on a global scale.
