Deradicalization in response to social experiences in youth in Hong Kong
Authors: Cheung Chau-kiu
Published: August 2022

Purpose

The study aims to examine the effectiveness of socially available measures such as concessive messaging, deradicalizing messaging, punishment, and reward in deradicalization, which remains theoretically debatable and empirically unclear and concern social policymakers.

Design/methodology/approach

This study surveyed 4,385 Chinese youths in Hong Kong, a special administrative region of China, to clarify the effectiveness.

Findings

Results show that receiving concessive messages about radicalism raised radicalism in 2020. Meanwhile, receiving deradicalization messages and rewards reduced radicalism. Receiving punishments for radicalism reduced radicalism when radicalism in 2019 had been high.

Originality/value

These results support social learning theory and imply its usefulness for deradicalization. That is, deradicalization can rely on messaging countering as opposed to conceding to radicalism and reinforcement for deradicalization and against radicalism.
Women in Latin American family businesses: an institutional logics perspective
Authors: Samara Georges , Lapeira Maria
Published: August 2022

Purpose

The authors conceptually theorize the obstacles and opportunities that women encounter in family businesses embedded in Latin America, by differentiating between two clusters of countries embedded in this continent.

Design/methodology/approach

Using secondary data obtained from various sources, the authors adopted a flexible pattern matching methodology, which involves linking theoretical propositions with actual observed patterns. For each proposition, the authors categorize the comparison with the observed data as either confirming or rivaling the expected patterns in the clusters.

Findings

This study’s findings reveal that women have more leadership and employment opportunities in the first cluster (Brazil, Chile, and Mexico) than in the second (Argentina, Colombia, and Peru). The authors propose that these differences are the result of higher tolerance for women in political leadership positions and of the presence of larger and more internationally expanding corporations in the first cluster. We also find differences between two groups of women: female family members and female nonfamily members, with the former being granted much more opportunities than the latter.

Practical implications

This research increases the understanding of potential avenues for managers and policymakers in Latin America to foster gender diversity as a means to remain competitive in a global market. While actions at the state level may be more long-term oriented, others, such as those taken by small and medium-sized family businesses may have more immediate effects in minimizing gender biases and encouraging a greater participation of females in business.

Originality/value

By differentiating between two clusters of countries in Latin America, and by making careful consideration of whether females have family ties, the authors provide a more realistic and contextualized theoretical map that depicts the situation of women in Latin American family businesses. This contextualization is one of the first that attempts to examine how multiple institutional logics impact women in family businesses in an underexplored region of the world while differentiating between female family members and female nonfamily members. These findings inform policymakers and family business owners in Latin America on the peculiar challenges that women encounter in their context, while calling for more measures promote the active presence of females in Latin American family businesses.
Mitigating seasonality in tourism by attracting young travellers: evidence from Cyprus
Authors: Liasidou Sotiroula , Berjozkina Galina , Pipyros Kosmas
Published: August 2022

Purpose

Generation Z, Millennials, young travellers or iGeneration represent the age range from 18 to 29 with uniquely different characteristics and tourism preferences. This study aims to understand the travel behaviour of young travellers in terms of the travel decisions they make and their involvement in tourism activity.

Design/methodology/approach

Primary data collection was facilitated by a focus group discussion with 12 participants from this age group.

Findings

Study results suggest that young travellers are attracted to technologically advanced destinations that provide multi-purpose experiences. Competitive tourism destinations are those adjusted to the needs of this cohort of travellers' propensity to embrace change and innovation. Considering the needs and expectations of young travellers is key to a destination's long-term survival and sustainability, as the market share of young travellers is rapidly growing.

Originality/value

The study looks at the trends in this emerging market segment and discusses new generational behaviour. Furthermore, the study provides insight into ways to make destinations attractive as year-round experiences and thereby control the problem of seasonality.
Effect of water availability on volatile‐mediated communication between potato plants in response to insect herbivory
Authors: Vázquez‐González Carla , Pombo‐Salinas Laura , Martín‐Cacheda Lucía , Rasmann Sergio , Röder Gregory , Abdala‐Roberts Luis , Mooney Kailen A. , Moreira Xoaquín
Published: August 2022

Airborne plant communication is a widespread phenomenon in which volatile organic compounds (VOCs) from damaged plants boost herbivore resistance in neighbouring, undamaged plants. Although this form of plant signalling has been reported in more than 30 plant species, there is still a considerable knowledge gap on how abiotic factors (e.g. water availability) alter its outcomes.

We performed a greenhouse experiment to test for communication between potato plants Solanum tuberosum in response to herbivory by the generalist insect Spodoptera exigua and whether communication was affected by water availability. We paired emitter and receiver potato plants, with half of the emitters damaged by S. exigua larvae and half serving as undamaged controls. Both emitter and receiver plants were factorially subjected to one of two watering treatments: high (i.e. well‐watered) vs. low (i.e. reduced watering) availability, thus effectively teasing apart water availability effects on the emission and reception components of signalling. After 4 days of herbivore feeding, we collected emitter VOCs and receivers were subjected to feeding by S. exigua to test for effects of signalling on induced resistance.

Herbivory by S. exigua led to increased VOCs emissions as well as changes in VOCs composition in emitter plants. Furthermore, emitters subjected to low water availability exhibited a weaker induction of VOCs in response to herbivory relative to well‐watered emitters. Results from the feeding bioassay indicated that receivers exposed to VOCs from herbivore‐induced emitters showed lower S. exigua damage (i.e. induced resistance) compared to receivers exposed to undamaged emitters. However, we did not observe a significant effect of water availability in either emitters or receivers on plant signalling effects on receiver resistance.

Overall, our study contributes to understanding how the abiotic context affects plant communication by providing evidence of water availability effects on the induction of VOCs that act as airborne signals between plants. The observed changes in induced VOCs due to the water treatment had no detectable consequences for plant communication. Accordingly, the induction of key compounds mediating communication was apparently not compromised by our experimental conditions.

Habitat loss increases seasonal interaction rewiring in plant–pollinator networks
Authors: Lázaro Amparo , Gómez‐Martínez Carmelo
Published: August 2022

Understanding the flexibility of interactions and network rewiring (i.e. reassembly of interactions due to partner‐switching) is necessary to comprehend how future anthropogenic changes will affect interspecific interactions and the functioning of communities. A higher rewiring could be expected in more disturbed landscapes because these landscapes contain fewer and more generalist species with more homogeneous traits.

We sampled pollination interactions in 20 wild Olea europaea communities along a disturbance gradient to evaluate the hypothesis that the loss of natural habitats increases seasonal (within‐year) interaction rewiring in plant‐pollinator communities, influencing their functional structure. For this, we particularly tested whether rewiring frequency was negatively related to the extent of natural habitats surrounding the communities, whether interaction rewiring influenced the static structure of networks (nestedness, network specialization –H2'–), and whether a high generalization (low specialization –d'–) and abundance of species in communities made them more prone to rewiring.

We show that habitat loss increased seasonal interaction rewiring in networks. Changes in rewiring were related to changes in the cumulative static structure of pollination networks. Nestedness decreased and network specialization (H2') also tended to decrease as interaction rewiring increased, suggesting an indirect effect of habitat loss on the robustness of networks through their dynamics. As expected, generalist insect and plant species were more prone to rewiring. However, flower abundance had different effects on the rewiring probability of plant species depending on the extent of habitat loss, with abundant species rewiring more in disturbed communities and rewiring less in more natural communities. Likely, this is related to the context‐dependent foraging behaviour of pollinators, which may switch to more abundant species if the cost of searching for trait‐matching resources is high in disturbed habitats.

Our work shows the role of partner‐switching in generalist species to adapt to new conditions. It also highlights the importance of going beyond general network metrics to understand the underlying processes of community‐level interaction assembly and predict and anticipate the effects of anthropogenic disturbances on pollination services.

Is the world wormier than it used to be? We'll never know without natural history collections
Authors: Wood Chelsea L. , Vanhove Maarten P. M.
Published: August 2022

Many disease ecologists and conservation biologists believe that the world is wormier than it used to be—that is, that parasites are increasing in abundance through time. This argument is intuitively appealing. Ecologists typically see parasitic infections, through their association with disease, as a negative endpoint, and are accustomed to attributing negative outcomes to human interference in the environment, so it slots neatly into our worldview that habitat destruction, biodiversity loss and climate change should have the collateral consequence of causing outbreaks of parasites.

But surprisingly, the hypothesis that parasites are increasing in abundance through time remains entirely untested for the vast majority of wildlife parasite species. Historical data on parasites are nearly impossible to find, which leaves no baseline against which to compare contemporary parasite burdens. If we want to know whether the world is wormier than it used to be, there is only one major research avenue that will lead to an answer: parasitological examination of specimens preserved in natural history collections.

Recent advances demonstrate that, for many specimen types, it is possible to extract reliable data on parasite presence and abundance. There are millions of suitable specimens that exist in collections around the world. When paired with contemporaneous environmental data, these parasitological data could even point to potential drivers of change in parasite abundance, including climate, pollution or host density change.

We explain how to use preserved specimens to address pressing questions in parasite ecology, give a few key examples of how collections‐based parasite ecology can resolve these questions, identify some pitfalls and workarounds, and suggest promising areas for research. Natural history specimens are ‘parasite time capsules’ that give ecologists the opportunity to test whether infectious disease is on the rise and to identify what forces might be driving these changes over time. This approach will facilitate major advances in a new sub‐discipline: the historical ecology of parasitism.

Published: August 2022

Obesity is associated with low‐grade inflammation and increased systemic oxidative stress. Roux‐en‐Y gastric bypass (RYGB) surgery is known to ameliorate the obesity‐induced metabolic dysfunctions. We aimed to study the levels of natural antibodies in feces, before and 6 months after RYGB surgery in obese individuals with and without type 2 diabetes (T2D). Sixteen individuals with T2D and 14 non‐diabetic (ND) individuals were operated. Total IgA, IgG and IgM antibody levels and specific antibodies to oxidized low‐density lipoprotein (oxLDL), malondialdehyde‐acetaldehyde adducts (MAA adducts), Porphyromonas gingivalis gingipain A hemagglutinin domain (Rgp44) and phosphocholine (PCho) were measured using chemiluminescence immunoassay. Total fecal IgA was elevated, while total IgM and IgG were not affected by the surgery. Fecal natural IgM specific to oxLDL decreased significantly in both T2D and ND individuals, while fecal IgM to Rgp44 and PCho decreased significantly in T2D individuals. A decrease in IgG to MAA‐LDL, Rgp44 and PCho was detected. RYGB surgery increases the levels of total fecal IgA and decreases fecal natural IgG and IgM antibodies specific to oxLDL. Natural antibodies and IgA are important in maintaining the normal gut homeostasis and first‐line defense against microbes, and their production is markedly altered with RYGB surgery.
Mud and glee at the crossroads: How can we consider intersectionality more holistically in academic fieldwork?
Authors: Lawrence Anya
Published: August 2022

Almost two decades after its original publication, I revisit Bracken and Mawdsley's ‘Muddy glee’; a landmark paper concerned with the inclusion of women in fieldwork. Whilst ‘Muddy glee’ made great strides towards raising awareness of gender discrimination in field‐based disciplines, I argue that greater understanding of intersectionality is needed to address the exclusion(s) that those with multiple markers of difference – including, but not limited to, gender – continue to face in academic fieldwork.

Authors: Araújo Letycia Monteiro Cavalcanti , Guimarães‐do‐Carmo Vinícius J. , Andrade Tácia Gabriela V. S. , Claudino Sabrina Cavalcanti , Soares Diego Moura , Melo Renato S.
Published: August 2022

Purpose

The purpose of this study is to observe the prevalence and intensity of musculoskeletal pain and the quality of life in mothers of children with microcephaly and also to compare the scores of the quality of life domains between mothers who had or did not have musculoskeletal pain.

Methods

This is a cross‐sectional study that evaluated mothers of children with a clinical diagnosis of microcephaly, due to congenital Zika virus syndrome, in the state of Pernambuco, northeast region, Brazil. To assess musculoskeletal pain, the Nordic Questionnaire of Musculoskeletal Symptoms was used, pain intensity was assessed by the Visual Analogue Scale and quality of life by the SF‐36 Questionnaire.

Results

Of the 63 mothers evaluated, 59 (93.7%) reported currently experiencing musculoskeletal pain. The lumbar spine was the body region with the highest prevalence of pain (77.8%), followed by the thoracic spine (57.1%) and cervical spine (50.8%). Pain intensity was higher in the lumbar spine (6.00 ± 0.47), thoracic spine (4.44 ± 0.52) and shoulders (3.81 ± 0.51). The domains that presented the lowest scores in the quality of life assessment were general health status (49.0 ± 3.19), emotional aspects (49.7 ± 5.88) and pain (49.7 ± 2.50). Mothers who had musculoskeletal pain had lower scores in all domains of quality of life assessment compared to mothers who did not have pain, demonstrating significant differences for functional capacity (P = 0.035), physical aspects (P = 0.047) and pain (P = 0.002).

Conclusion

A high prevalence of musculoskeletal pain was observed in mothers of children with microcephaly, with a higher prevalence and intensity in the lumbar spine. The domains related to physical and emotional health presented the worst scores in the quality of life of the evaluated mothers and the presence of musculoskeletal pain reduced the quality of life of the mothers of children with microcephaly in this study.
Rich Screen Reader Experiences for Accessible Data Visualization
Authors: Zong Jonathan , Lee Crystal , Lundgard Alan , Jang JiWoong , Hajas Daniel , Satyanarayan Arvind
Published: August 2022

Current web accessibility guidelines ask visualization designers to support screen readers via basic non‐visual alternatives like textual descriptions and access to raw data tables. But charts do more than summarize data or reproduce tables; they afford interactive data exploration at varying levels of granularity—from fine‐grained datum‐by‐datum reading to skimming and surfacing high‐level trends. In response to the lack of comparable non‐visual affordances, we present a set of rich screen reader experiences for accessible data visualization and exploration. Through an iterative co‐design process, we identify three key design dimensions for expressive screen reader accessibility: structure, or how chart entities should be organized for a screen reader to traverse; navigation, or the structural, spatial, and targeted operations a user might perform to step through the structure; and, description, or the semantic content, composition, and verbosity of the screen reader's narration. We operationalize these dimensions to prototype screen‐reader‐accessible visualizations that cover a diverse range of chart types and combinations of our design dimensions. We evaluate a subset of these prototypes in a mixed‐methods study with 13 blind and visually impaired readers. Our findings demonstrate that these designs help users conceptualize data spatially, selectively attend to data of interest at different levels of granularity, and experience control and agency over their data analysis process.

Effective Use of Likert Scales in Visualization Evaluations: A Systematic Review
Authors: South Laura , Saffo David , Vitek Olga , Dunne Cody , Borkin Michelle A.
Published: August 2022

Likert scales are often used in visualization evaluations to produce quantitative estimates of subjective attributes, such as ease of use or aesthetic appeal. However, the methods used to collect, analyze, and visualize data collected with Likert scales are inconsistent among evaluations in visualization papers. In this paper, we examine the use of Likert scales as a tool for measuring subjective response in a systematic review of 134 visualization evaluations published between 2009 and 2019. We find that papers with both objective and subjective measures do not hold the same reporting and analysis standards for both aspects of their evaluation, producing less rigorous work for the subjective qualities measured by Likert scales. Additionally, we demonstrate that many papers are inconsistent in their interpretations of Likert data as discrete or continuous and may even sacrifice statistical power by applying nonparametric tests unnecessarily. Finally, we identify instances where key details about Likert item construction with the potential to bias participant responses are omitted from evaluation methodology reporting, inhibiting the feasibility and reliability of future replication studies. We summarize recommendations from other fields for best practices with Likert data in visualization evaluations, based on the results of our survey.

SurfNet: Learning Surface Representations via Graph Convolutional Network
Authors: Han Jun , Wang Chaoli
Published: August 2022

For scientific visualization applications, understanding the structure of a single surface (e.g., stream surface, isosurface) and selecting representative surfaces play a crucial role. In response, we propose SurfNet, a graph‐based deep learning approach for representing a surface locally at the node level and globally at the surface level. By treating surfaces as graphs, we leverage a graph convolutional network to learn node embedding on a surface. To make the learned embedding effective, we consider various pieces of information (e.g., position, normal, velocity) for network input and investigate multiple losses. Furthermore, we apply dimensionality reduction to transform the learned embeddings into 2D space for understanding and exploration. To demonstrate the effectiveness of SurfNet, we evaluate the embeddings in node clustering (node‐level) and surface selection (surface‐level) tasks. We compare SurfNet against state‐of‐the‐art node embedding approaches and surface selection methods. We also demonstrate the superiority of SurfNet by comparing it against a spectral‐based mesh segmentation approach. The results show that SurfNet can learn better representations at the node and surface levels with less training time and fewer training samples while generating comparable or better clustering and selection results.
Six methods for transforming layered hypergraphs to apply layered graph layout algorithms
Authors: Di Bartolomeo Sara , Pister Alexis , Buono Paolo , Plaisant Catherine , Dunne Cody , Fekete Jean‐Daniel
Published: August 2022

Hypergraphs are a generalization of graphs in which edges (hyperedges) can connect more than two vertices—as opposed to ordinary graphs where edges involve only two vertices. Hypergraphs are a fairly common data structure but there is little consensus on how to visualize them. To optimize a hypergraph drawing for readability, we need a layout algorithm. Common graph layout algorithms only consider ordinary graphs and do not take hyperedges into account. We focus on layered hypergraphs, a particular class of hypergraphs that, like layered graphs, assigns every vertex to a layer, and the vertices in a layer are drawn aligned on a linear axis with the axes arranged in parallel. In this paper, we propose a general method to apply layered graph layout algorithms to layered hypergraphs. We introduce six different transformations for layered hypergraphs. The choice of transformation affects the subsequent graph layout algorithm in terms of computational performance and readability of the results. Thus, we perform a comparative evaluation of these transformations in terms of number of crossings, edge length, and impact on performance. We also provide two case studies showing how our transformations can be applied to real‐life use cases.

Exploring Multivariate Event Sequences with an Interactive Similarity Builder
Authors: Xu Shaobin , Sun Minghui , Zhang Zhengtai , Xue Hao
Published: August 2022

Similarity‐based exploration is an effective method in knowledge discovery. Faced with multivariate event sequence data (MVES), developing a satisfactory similarity measurement for a specific question is challenging because of the heterogeneity introduced by numerous attributes with different data formats, coupled with their associations. Additionally, the absence of effective validation feedback makes judging the goodness of a measurement scheme a time‐consuming and error‐prone procedure. To free analysts from tedious programming to concentrate on the exploration of MVES data, this paper introduces an interactive similarity builder, where analysts can use visual building blocks for assembling similarity measurements in a drag‐and‐drop and incremental fashion. Based on the builder, we further propose a visual analytics framework that provides multi‐granularity visual validations for measurement schemes and supports a recursive workflow for refining the focus set. We illustrate the power of our prototype through a case study and a user study with real‐world datasets. Results suggest that the system improves the efficiency of developing similarity measurements and the usefulness of exploring MVES data.
A Flip‐book of Knot Diagrams for Visualizing Surfaces in 4‐Space
Authors: Liu Huan , Zhang Hui
Published: August 2022

Just as 2D shadows of 3D curves lose structure where lines cross, 3D graphics projections of smooth 4D topological surfaces are interrupted where one surface intersects itself. They twist, turn, and fold back on themselves, leaving important but hidden features behind the surface sheets. In this paper, we propose a smart slicing tool that can read the 4D surface in its entropy map and suggest the optimal way to generate cross‐sectional images — or “slices” — of the surface to visualize its underlying 4D structure. Our visualization thinks of a 4D‐embedded surface as a collection of 3D curves stacked in time, very much like a flip‐book animation, where successive terms in the sequence differ at most by a critical change. This novel method can generate topologically meaningful visualization to depict complex and unfamiliar 4D surfaces, with the minimum number of cross‐sectional diagrams. Our approach has been successfully used to create flip‐books of diagrams to visualize a range of known 4D surfaces. In this preliminary study, our results show that the new visualization and slicing tool can help the viewers to understand and describe the complex spatial relationships and overall structures of 4D surfaces.
LOOPS: LOcally Optimized Polygon Simplification
Authors: Amiraghdam Alireza , Diehl Alexandra , Pajarola Renato
Published: August 2022

Displaying polygonal vector data is essential in various application scenarios such as geometry visualization, vector graphics rendering, CAD drawing and in particular geographic, or cartographic visualization. Dealing with static polygonal datasets that has a large scale and are highly detailed poses several challenges to the efficient and adaptive display of polygons in interactive geographic visualization applications. For linear vector data, only recently a GPU‐based level‐of‐detail (LOD) polyline simplification and rendering approach has been presented which can perform locally‐adaptive LOD visualization of large‐scale line datasets interactively. However, locally optimized LOD simplification and interactive display of large‐scale polygon data, consisting of filled vector line loops, remains still a challenge, specifically in 3D geographic visualizations where varying LOD over a scene is necessary. Our solution to this challenge is a novel technique for locally‐optimized simplification and visualization of 2D polygons over a 3D terrain which features a parallelized point‐inside‐polygon testing mechanism. Our approach is capable of employing any simplification algorithm that sequentially removes vertices such as Douglas‐Peucker and Wang‐Müller. Moreover, we generalized our technique to also visualizing polylines in order to have a unified method for displaying both data types. The results and performance analysis show that our new algorithm can handle large datasets containing polygons composed of millions of segments in real time, and has a lower memory demand and higher performance in comparison to prior methods of line simplification and visualization.
Misinformed by Visualization: What Do We Learn From Misinformative Visualizations?
Authors: Lo Leo Yu‐Ho , Gupta Ayush , Shigyo Kento , Wu Aoyu , Bertini Enrico , Qu Huamin
Published: August 2022

Data visualization is powerful in persuading an audience. However, when it is done poorly or maliciously, a visualization may become misleading or even deceiving. Visualizations give further strength to the dissemination of misinformation on the Internet. The visualization research community has long been aware of visualizations that misinform the audience, mostly associated with the terms “lie” and “deceptive.” Still, these discussions have focused only on a handful of cases. To better understand the landscape of misleading visualizations, we open‐coded over one thousand real‐world visualizations that have been reported as misleading. From these examples, we discovered 74 types of issues and formed a taxonomy of misleading elements in visualizations. We found four directions that the research community can follow to widen the discussion on misleading visualizations: (1) informal fallacies in visualizations, (2) exploiting conventions and data literacy, (3) deceptive tricks in uncommon charts, and (4) understanding the designers' dilemma. This work lays the groundwork for these research directions, especially in understanding, detecting, and preventing them.
Haematological changes from conception to childbirth: An indicator of major pregnancy complications
Authors: Patxot Marion , Stojanov Miloš , Ojavee Sven Erik , Gobert Rosanna Pescini , Kutalik Zoltán , Gavillet Mathilde , Baud David , Robinson Matthew R.
Published: August 2022

Background

About 800 women die every day worldwide from pregnancy‐related complications, including excessive blood loss, infections and high‐blood pressure (World Health Organization, 2019). To improve screening for high‐risk pregnancies, we set out to identify patterns of maternal hematological changes associated with future pregnancy complications.

Methods

Using mixed effects models, we established changes in 14 complete blood count (CBC) parameters for 1710 healthy pregnancies and compared them to measurements from 98 pregnancy‐induced hypertension, 106 gestational diabetes and 339 postpartum hemorrhage cases.

Results

Results show interindividual variations, but good individual repeatability in CBC values during physiological pregnancies, allowing the identification of specific alterations in women with obstetric complications. For example, in women with uncomplicated pregnancies, haemoglobin count decreases of 0.12 g/L (95% CI −0.16, −0.09) significantly per gestation week (p value <.001). Interestingly, this decrease is three times more pronounced in women who will develop pregnancy‐induced hypertension, with an additional decrease of 0.39 g/L (95% CI −0.51, −0.26). We also confirm that obstetric complications and white CBC predict the likelihood of giving birth earlier during pregnancy.

Conclusion

We provide a comprehensive description of the associations between haematological changes through pregnancy and three major obstetric complications to support strategies for prevention, early‐diagnosis and maternal care.
Contributors are representative, as long as they agree: How confirmation logic overrides effort to achieve synthesis in applied health research
Authors: Knowles Sarah E. , Walkington Pat , Flynn Jackie , Darley Sarah , Boaden Ruth , Kislov Roman
Published: August 2022

Introduction

The paradox of representation in public involvement in research is well recognized, whereby public contributors are seen as either too naïve to meaningfully contribute or too knowledgeable to represent ‘the average patient’. Given the underlying assumption that expertise undermines contributions made, more expert contributors who have significant experience in research can be a primary target of criticism. We conducted a secondary analysis of a case of expert involvement and a case of lived experience, to examine how representation was discussed in each.

Methods

We analysed a case of a Lived Experience Advisory Panel (LEAP) chosen for direct personal experience of a topic and a case of an expert Patient and Public Involvement (PPI) panel. Secondary analysis was of multiple qualitative data sources, including interviews with the LEAP contributors and researchers, Panel evaluation data and documentary analysis of researcher reports of Panel impacts. Analysis was undertaken collaboratively by the author team of contributors and researchers.

Results

Data both from interviews with researchers and reported observations by the Panel indicated that representation was a concern for researchers in both cases. Consistent with previous research, this challenge was deployed in response to contributors requesting changes to researcher plans. However, we also observed that when contributor input could be used to support research activity, it was described unequivocally as representative of ‘the patient view’. We describe this as researchers holding a confirmation logic. By contrast, contributor accounts enacted a synthesis logic, which emphasized multiplicity of viewpoints and active dialogue. These logics are incompatible in practice, with the confirmation logic constraining the potential for the synthesis logic to be achieved.

Conclusion

Researchers tend to enact a confirmation logic that seeks a monophonic patient voice to legitimize decisions. Contributors are therefore limited in their ability to realize a synthesis logic that would actively blend different types of knowledge. These different logics hold different implications regarding representation, with the synthesis logic emphasizing diversity and negotiation, as opposed to the current system in which ‘being representative' is a quality attributed to contributors by researchers.

Published: August 2022

This study aims to investigate how the predeposition machining processes such as magnetic grinding, turning machining, and wire electrical discharge machining can influence the surface properties including electrochemical and tribological behavior of TiCrN nanostructured coating applied on Mo40 steel substrate. A physical vapor deposition technique using cathodic arc evaporation was used to apply the coating. The crystallographic phases and the microstructure of the coating were studied by X‐ray diffraction and scanning electron microscope, respectively. Rockwell‐C, electrochemical impedance spectroscopy and potentiodynamic polarization, and pin‐on‐disk wear tests were employed to evaluate the adhesion strength, corrosion behavior, and tribological property of specimens, respectively. The electrochemical results after 24 h of exposure to 3.5 wt% NaCl solution showed that TiCrN coating pretreated with a turning process with polarization resistance of about 3525.32 Ω.cm2 had the best corrosion resistance among all specimens. This was because of the improvement of the smoothness, surface quality, and adhesion after the turning process. On the other, the friction coefficient of the grounded sample is less than that of other ones. This is probably due to its higher adhesion strength and higher surface smoothness.

Published: August 2022

Background

Sporotrichosis is a subcutaneous mycosis caused by dimorphic fungi of the genus Sporothrix. The route of entry of the causative agent is direct inoculation by skin trauma, generally with decaying wood and other vegetation. However, cat‐transmitted sporotrichosis has become more relevant in recent decades especially in South America. Until now, there are no case reports of cat‐transmitted sporotrichosis in Colombia.

Case report

We present three cases of cutaneous sporotrichosis after the scratches of an ill cat, in the feline's owners and its veterinarian, confirmed by culture and PCR, where S. schenckii sensu stricto was isolated and typified.

Conclusions

Cat‐transmitted sporotrichosis is becoming more relevant in recent decades due to its potential to generate epidemics and become a public health problem. In addition, since the associated species are more virulent, the disease has more aggressive behavior. In Colombia, this is the first case series of cat‐transmitted cutaneous sporotrichosis.
Effects of iron supplementation on microcytic and hypochromic red blood cells during the third trimester of pregnancy
Authors: Schoorl Margreet , Schoorl Marianne
Published: August 2022

Introduction

Mild anaemia often occurs in the third trimester of pregnancy. Particularly in the Hb range between 101–110 g/L it is difficult to determine whether the decreased haemoglobin concentration is physiological or pathological and whether supplementation is required.

The aim of this study was to gain insight into the added value of measuring the percentages of microcytic RBCs (%MicroR) and hypochromic RBCs (%Hypo‐He) for monitoring effects of iron supplementation in case of suspected iron‐deficient erythropoiesis (IDE) in the third trimester of pregnancy.

Methods

After assessing haematological parameters and zinc protoporphyrin/heme ratio as marker for IDE, subjects were classified into a group with symptoms of IDE (n = 39) or without IDE (n = 106). The subjects with IDE (n = 39) were treated with iron supplementation. After 4 weeks effects of treatment were evaluated.

Results

In the group of pregnant women with IDE results of %MicroR and %Hypo‐He were increased (p = <.001), compared to the group without haematological symptoms of IDE, whereas RET‐He, RBC‐He and delta‐He were decreased (p = <.001).

A significant positive correlation to increased values of %MicroR (r = .75,p = <.001) and %Hypo‐He (r = .77,p = <.001) with ZPP was established. However, in the ZPP interval 75–100 μmol/mol heme a slight overlap was demonstrated between subjects with and without symptoms of IDE.

After iron supplementation, %Hypo‐He decreased (p = .002) while %MicroR remained stable. RET‐He, delta‐He and RDW‐SDincreased (p = <.001).

Conclusion

The added value of %MicroR and %Hypo‐He as a single marker for IDE is poor. However, combined interpretation of %MicroR, %Hypo‐He, Ret‐He and delta‐He has added value in monitoring erythropoiesis during pregnancy.

Developmental theories have proposed caregiver reactions, in particular caregivers' moral reasoning with their children, as crucial factors in children's developing morality. Yet, empirical evidence is scarce and mainly restricted to laboratory contexts. Here, we used the ambulatory assessment method to investigate how caregiver responses to moral transgressions longitudinally relate to children's emerging moral agency. On the first measurement point, mothers (N = 220) reported on nine consecutive evenings on a moral transgression of their 5‐ to 46‐month‐olds', their emotional and verbal reactions, and how in turn their child reacted. Five months later, mothers reported on their child's aggressive and prosocial (helping, sharing, comforting) behavior. Our results demonstrated that (1) caregiver reasoning supported children's sharing and comforting behavior and was related to lower levels of children's aggressive behavior half a year later, that (2) caregiver reasoning reactions supported children's negative evaluations of their own transgressions while compliance‐based caregiver reactions (e.g., physical interventions, reprimands) were predictive of children's subsequent emotional distress and anger, and that (3) caregiver social conformity and reflective functioning abilities emerged as determinants of caregiver negative moral emotions. Thus, this study uses an innovative methodological approach to uncover key characteristics of caregiver moral reactions supporting the development of morality.

Aims

In this study, we sought to determine the pathogenic ability of endophytic fungi recovered from the spines of Calamus castaneus, a common rattan palm growing in the forests of Peninsula Malaysia.

Methods and Results

Ten endophytic fungal isolates were selected for pathogenicity tests: Colletotrichum boninense, Colletotrichum fructicola, Colletotrichum cliviae, Diaporthe hongkongensis, Diaporthe arengae, Diaporthe cf. nobilis, Neopestalotiopsis saprophytica, Neopestalotiopsis formicarum, Fusarium solani and Fusarium oxysporum. These endophytes were tested against leaves of bertam (Eugeissona sp.), oil palm (Elaeis guineensis) and mango (Mangiferae indica) and the fruits of chilli (Capsicum annum), tomato (Solanum lycopersicum) and banana (Musa acuminata). The fungal isolates showed infectivity against bertam, oil palm and mango leaves with degrees of virulence ranging from low to moderate, whereas infectivity against chilli, tomato and banana ranged from low to very high.

Conclusions

Fungal endophytes isolated from the spines of C. castaneus are pathogenic to different crop plants with differing degrees of virulence or aggressiveness.

Significance and Impact of the Study

Spines of C. castaneus can harbour fungal pathogens of a number of different crops as endophytes. The ability of the fungal endophytes to colonize and infect different crops demonstrate their importance towards agricultural crops. There is a possibility the endophytes behave as latent pathogen. When conditions become favourable, the fungal endophytes transform to pathogenic form and potentially infect other plants.

Aim

To explore clinical supervisors' perceptions and use of the Fundamentals of Care framework in supervising nursing students in clinical placement in hospital settings.

Design

A qualitative study using focus group interviews. Reported in accordance with Consolidated Criteria for Reporting Qualitative Research.

Methods

Twelve clinical nurse supervisors working in medical, surgical or psychiatric wards in hospitals in Denmark participated in four focus groups conducted from September to November 2020. Data were analysed using thematic analysis.

Results

Clinical supervisor's perceptions and use of the framework are described in three themes: structuring students' clinical learning, supporting tool for learning what nursing care is and developing own supervision practice.

Conclusion

Supervisors perceive the Fundamentals of Care framework positively and use it as a supporting tool to structure and facilitate students' reflection on what nursing is and requires. They perceive that having a shared framework across school and clinical setting contributes to a safe and positive learning environment. Furthermore, using the framework develops their own practice as clinical supervisors.

In three experiments, we examine the role of motives underlying goal pursuit and the metacognitive strategy of mental contrasting with implementation intentions (MCII) to predict the strategic use of self‐regulation responses (persistence, disengagement, and reengagement) when faced with attainable, unattainable, or multiple goals. We trained half of the participants to use MCII and treated the rest as control. Experiment 1 (N = 261) underscored the role of autonomous motivation in nurturing adaptive cognitive appraisals and coping mechanisms, which facilitated persistence and progress with a difficult but attainable goal. In contrast, controlled motives undermined striving by predicting threat appraisals and giving up coping. MCII training ameliorated the negative impact of controlled motivation on goal striving by reducing threat appraisals. In Experiment 2 (N = 391), we manipulated the task to make the initial goal unattainable. Strategic goal striving (disengagement from the unattainable goal followed by reengagement with an alternative goal) was facilitated by MCII and autonomous goal motives, and culminated in increases in positive affect. In Experiment 3 (N = 432), we extended these findings to a multiple‐goal setting. The research further develops the literatures on self‐regulation and self‐determination, while having implications for life domains where individuals pursue multiple and/or difficult goals.
Power at work: Linking objective power to psychological power

Experimental research conducted with student participants has documented that feeling powerful or powerless (psychological power) affects outcomes with high practical relevance for organizations. However, it is unclear how results from these studies can be generalized to organizational settings in which individuals have various roles that imply more or less objective power. To address this gap, we present a theoretical framework to aid in the understanding of how objective power in organizations affects psychological power. We assume that stable differences in organizational rank (i.e., structural power) determine the likelihood of interactions with superiors, subordinates, or peers. These interactions give rise to within‐person variation in situational power which should lead to dynamic fluctuations of psychological power and eventually its outcomes. Results of a preregistered experiment (n = 190 participants) and a preregistered experience sampling study (n = 129 participants) conducted with working adults support our key predictions: Structural power was associated with the likelihood of being in a high power versus low power situation. Within‐person differences in situational power were related to feelings of power such as judgments about (1) one's own ability to influence others in a given social situation (i.e., interpersonal power) and (2) one's own competence, agency, autonomy, and independence (i.e., personal power).
