Important drivers for customer satisfaction – a Swedish crisis reflection
Authors: Hallencreutz Jacob , Parmler Johan , Westin Love
Published: May 2024

Purpose

The purpose of this study is to examine crisis effects on customer satisfaction and underlying drivers by adding a new set of data to previous research. The core questions are: are the findings from Hallencreutz and Parmler (2019, 2021) sustained or can new customer demands, needs, expectations and behaviours be traced in the wake of the ongoing crisis?

Design/methodology/approach

A first study covering 2005–2017 was completed in 2018, published online in 2019 and in print in 2021 (Hallencreutz and Parmler, 2021). This new study adds the years 2018–2023 to the data set and reuses the partial least squares (PLS) approach to structural equation models, also known as PLS path modelling.

Findings

This additional study sustains the results from the initial study (Hallencreutz and Parmler, 2019, 2021). The variable product quality has been substituted by service quality as one of the most crucial drivers for customer satisfaction together with brand image, and the current state of permacrisis has not changed that.

Research limitations/implications

The study is built on Swedish data from the EPSI Rating Initiative (Eklöf and Westlund 2002) covering customer perceptions in banking, insurance (life and non-life), telco (mobile operators, broadband and Pay-tv) and energy (trade, distribution and heating) over the years 2005–2023.

Practical implications

The study emphasizes the importance of understanding how customer satisfaction drivers evolve over time in different industries and societal sectors, especially during crises. This additional study sustains the paradigm shift in the studied industries – product quality has been substituted by service quality as one of the most crucial drivers for customer satisfaction, and the current state of economic downturn has not changed that.

Social implications

Society will have to learn to live with political and economic instability and unpredictability for the foreseeable future. To recognize the increasing value deriving from firms’ intangible assets while providing flawless deliveries seems to be a way forward in troublesome times. This is also a catalyst for existing societal trends: the necessary reforms to master sustainable transformations will require an ongoing adaptation process, with both winners and losers across continents.

Originality/value

The world has coped with a global pandemic, and Europe is currently experiencing a humanitarian, political and economic crises caused by a war in Ukraine. This extended period of global instability and insecurity could be called a permacrisis (Collins dictionary, 2022). This study offers a unique quantitative analysis built on Swedish data from EPSI Rating initiative.
Sustaining spontaneous volunteer groups following their response to a disaster
Authors: Shaw Duncan , Zanjirani Farahani Reza , Scully Judy
Published: May 2024

Purpose

This research explores the drivers that determine the ability of spontaneous volunteer groups (SVGs) to sustain their operations. That sustainability aims to support those affected in the community beyond the response phases of a disaster and into the recovery and mitigation phases to build resilience to the next disaster.

Design/methodology/approach

To investigate the sustainability of spontaneous volunteering that takes place in the aftermath of a disaster, we conducted qualitative interviews in three English locations where groups of spontaneous volunteers emerged following major floods. We analysed our qualitative data using thematic analysis.

Findings

Our findings theorise the drivers of SVG sustainability and present these in four themes: (1) assessment of ongoing needs; (2) organisation of resources to address that need; (3) leadership and followership creating a weight of operational capability and (4) influence of political will. Through exploring these drivers, we uncover key factors to developing a sustainable SVG system including trusted leadership and social capital.

Research limitations/implications

We show how the four drivers interact to support the continuity of SVGs and sustain their operations. This has implications for how leaders of SVGs create a volunteering environment that encourages ongoing involvement and has implications for officials to view SVGs as a support rather than a risk.

Originality/value

The novelty of our paper is in rejecting the argument of the temporal limit of SVGs to the response phase by theorising the drivers that make their operations sustainable for recovery and resilience building to mitigate the next disaster. This includes our examination of the interplay between those drivers.
Caring for our planet: a world apart or same difference? A global music collaboration
Authors: Wilson Emily , Black Pauline
Published: May 2024

Purpose

The impact and collective threat of climate change is of key concern to all. Music and arts education can play a role by responding to the ongoing climate crisis through the creation of artworks as activism. This paper discusses a collaborative online international music project and its potential contribution to sustainable development education.

Design/methodology/approach

10,427 miles and 11 hours apart, music education students undertook the project, working in groups with a mix of students from Aberdeen, Scotland and Melbourne, Australia in each group. Each student collected video footage that captured their experience of climate concerns related to their environment. Students combined and edited the footage then collaboratively composed music to accompany the footage. This research was conceived as a collaborative self-study project undertaken by the authors as music teacher educators.

Findings

The results show a range of musical and extra musical outcomes and challenges. Evidence suggests that a collaborative online international music learning experience may contribute to sustainable development education and regenerative practice more broadly. Students began to develop their practice as educators for school and community contexts embedding learning for sustainability and climate consciousness, thus enabling them to develop as active global citizens.

Originality/value

This paper argues for greater attention to the affordances of digital collaborative music technology tools to facilitate creative projects as well as the need to reimagine musical experience, drawing together strands of music, sustainability education, technology and global citizenship. This paper also argues for the importance of embedding the UN Sustainable Development Goals in teaching and learning in Higher Education.
The influence of electronic word of mouth on green cosmetics purchase intention: evidence from young Vietnamese female consumers
Authors: Nguyen Thuy Thi Thu , Limbu Yam B. , Pham Long , Zúñiga Miguel Ángel
Published: May 2024

Purpose

This study aims to examine the direct and indirect influence of electronic word of mouth (eWOM) on green cosmetics purchase intention of young Vietnamese female consumers through health concern, environmental concern and the theory of planned behavior (TPB) factors.

Design/methodology/approach

Data were collected from a survey of Vietnamese young female consumers that were analyzed using a partial least squares structural equation modeling.

Findings

The results reveal that eWOM has a direct effect on consumers’ purchase intention of green cosmetics. Among TPB factors, attitude was a greater influential predictor of purchase intention than subjective norms. However, the influence of perceived behavioral control on purchase intention was not supported. There were significant indirect effects of eWOM on purchase intention through the mediation of health concern, environmental concern and attitude.

Practical implications

Therefore, the findings of this study are relevant for marketers and managers as they provide valuable insights into understanding the motivational factors of consumers’ green cosmetics purchase intention. The results highlighted that eWOM could increase young female consumers’ environmental concern and health concern, which, in turn, influence a positive attitude toward green cosmetics. Hence, eWOM is a powerful vehicle for environmental and health messages; also, it can be an important channel of sensitization toward environmental and health issues and motivation of proenvironmental behavior and healthy lifestyle.

Originality/value

The study contributed to the literature by confirming the utility of the TPB model in predicting young women’s green cosmetics purchases in the context of Vietnam, an emerging market, which has largely been overlooked in the literature. The findings show that eWOM has a direct influence on green cosmetics purchase intentions of young Vietnamese female consumers and indirectly eWOM through health concern, environmental concern and two TPB factors (attitude and subjective norms).
Analyzing the role of social value in megaprojects: toward a new performance framework
Authors: De Nito Ernesto , Caccialanza Andrea , Canonico Paolo , Favari Edoardo
Published: May 2024

Purpose

Megaprojects stimulate and challenge public opinion across countries, generating extensive reactions from citizens. Given their ability to attract public attention, they may also influence public participation in collective choices and political decision-making. These issues are relevant for evaluating projects, but are unfortunately rarely discussed in the managerial literature. This study aims to open up a debate on social issues and how they could be taken into account within management studies.

Design/methodology/approach

This study carried out a systematic review of the literature on the social impact of megaprojects to identify different research areas related to the evaluation of megaprojects from a social perspective.

Findings

This study identified three different research areas related to the evaluation of megaprojects from a social perspective: the role of power and social issues; infrastructure and social space; and stakeholder engagement and endorsement.

Originality/value

This paper underlines the need to go beyond current understanding of the social impacts of megaprojects and calls for a more interdisciplinary research agenda.

Authors: Baig Atif , Mann Robin , Lockhart James , Macpherson Wayne
Published: May 2024

Purpose

The purpose of this study is to address a critical gap in the existing literature on business excellence implementation. While various studies have examined different aspects of business excellence, there is still a lack of comprehensive research on the optimal organizational excellence architecture (OEA) for an award-winning business excellence journey. The absence of a unified framework has led to inconsistent practices across organizations. The aim of this research based on data collected from 50 organizations across 17 countries is to address this gap and present a refined OEA model.

Design/methodology/approach

This study employed quantitative and qualitative data collection methods. Member organizations from the Global Excellence Model (GEM) Council participated through an online survey administered via the Qualtrics software platform. Quantitative data were analyzed using the SPSS and Microsoft Excel software tools, while content analysis techniques were applied to the qualitative data to gain detailed insights.

Findings

The findings refine and extend the OEA model. These contributions lead to a refined OEA definition and open avenues for future research, enriching the current understanding of BE implementation.

Originality/value

This study introduces a novel concept of OEA to the literature on business excellence implementation. The refined OEA model provides a fresh perspective on the critical components necessary for an award-winning business excellence journey. This research offers significant value to both practitioners and academics by presenting a unified approach to BE implementation, effectively addressing the previously identified gap in BE research.

Analyzing social media reactions to the FTX crisis: Unraveling the spillover effect on crypto markets
Authors: Lee Chunsik , Lee Suan , Kim Junga , Lim Joon Soo
Published: May 2024

In this study, we analyzed social media conversations during the unfolding of the FTX crisis, the biggest cryptocurrency scandal in United States history. Drawing on the accessibility‐diagnosticity framework, we examined the negative spillover effect of the crisis using a natural language processing approach. We specifically assessed whether there was a negative spillover from FTX to other crypto entities with different levels of diagnostic attribute similarity. We collected a large corpus of Twitter conversations related to the FTX collapse in 2022 and used the association rule analysis to determine the association between FTX and other crypto entities. Our analysis revealed that the number of tweets mentioning FTX and other crypto entities changed in line with a series of real‐world events during the FTX crisis. The negative spillover of the FTX crisis occurred primarily during the first 10 days as the FTX scandal unfolded. The results indicated that the FTX crisis spilled over to highly accessible and diagnostic crypto entities, such as Binance, Bitcoin, and the cryptocurrency industry in general. On the other hand, less accessible and less diagnostic crypto entities/currencies like Ethereum and Coinbase did not experience negative spillover from the scandal.
The influence of rehydration on decomposition in the Highveld region of South Africa—Using a pig model
Authors: du Toit Claire Lynne , Myburgh Jolandie , Brits Desiré
Published: May 2024

Researchers have observed that rainfall may re‐initiate decomposition in desiccated tissue; however, no conclusive research‐based evidence exists on the specific effects of rehydration on decomposition. Therefore, this study aimed to assess the effects of artificial rehydration on the progression of decomposition following the advanced stage of decomposition. Twelve adult pig cadavers (8 experimental; 4 controls) were placed in the central Highveld of South Africa during cooler (April–July 2021) and warmer (August–November 2021) months. Decomposition was scored approximately biweekly to obtain the total body score, and accumulated degree days (ADD) were calculated for each pig. All pig cadavers were covered by chicken wire cages with transparent tarps to control for natural rehydration and scavenging. Once the experimental pig cadavers reached a three‐visit stasis in the advanced phase of decomposition, they were artificially rehydrated, and changes in the progression of decomposition between the control and experimental groups were plotted (ADD against TBS) for observation. The rehydrated experimental pig cadavers showed re‐initiation of decay and insect re‐colonization, while the control cadavers mainly remained in a state of stasis with insect activity ceased altogether. Greater cadaver decomposition islands and a color change post‐rehydration were also noted in some experimental cadavers. This supports the need for future research on the impact of rehydration, including associated soil moisture on decomposition rates, progression, and invertebrate colonization, which will enhance our understanding of the effects these environmental factors have on the accuracy of post‐mortem interval estimation.
Hypoxia differently regulates the proportion of ALDHhi cells in lung squamous carcinoma H520 and adenocarcinoma A549 cells via the Wnt/β‐catenin pathway
Authors: Liu Ni , Zheng Qi , Zhang Yuqing , Wang Huimin , Zhang Zhihui , He Long , Wei Chenxi , Xia Handai , Liu Yanguo , Wang Xiuwen
Published: May 2024

Background

Cancer stem cells (CSCs) are a specific subpopulation of cancer cells with the ability of self‐renewal, infinite proliferation, multidifferentiation and tumorigenicity, and play critical roles in cancer progression and treatment resistance. CSCs are tightly regulated by the tumor microenvironment, such as hypoxia; however, how hypoxia regulates CSCs in non‐small cell lung cancer (NSCLC) remains unclear.

Methods

The proportion of ALDHhi cells was examined using the Aldefluor assay. Tankyrase inhibitor XAV939 and siRNA were used to inhibit β‐catenin while pcDNA3‐β‐catenin (S33Y) plasmid enhanced the expression of β‐catenin. Western blot was administered for protein detection. The mRNA expression was measured by quantitative real‐time PCR.

Results

We found that hypoxia led to an increase in the proportion of ALDHhi cells in lung squamous carcinoma (LUSC) H520 cells, while causing a decrease in the ALDHhi cell proportion in lung adenocarcinoma (LUAD) A549 cells. Similarly, β‐catenin expression was upregulated in H520 cells but downregulated in A549 cells upon exposure to hypoxia. Mechanically, the proportion of ALDHhi cells in both cell lines was decreased by β‐catenin inhibitor or siRNA knockdown, whereas increased after β‐catenin overexpression. Furthermore, hypoxia treatment suppressed E‐cadherin expression in H520 cells and enhanced N‐cadherin and β‐catenin expression, while this effect was completely opposite in A549 cells.

Conclusion

The hypoxia‐EMT‐β‐catenin axis functions as an important regulator for the proportion of CSCs in NSCLC and could potentially be explored as therapeutic targets in the future.
Unexpected effect of geographic origin on post‐translocation survival in a long‐lived reptile, the gopher tortoise
Authors: Loope K. J. , Cozad R. A. , Breakfield D. B. , Aresco M. J. , Hunter E. A.
Published: May 2024

Mitigation translocations move wildlife from specific areas due to conflict with humans over land use at the site. A critical decision when carrying out mitigation translocation is the acceptable distance across which animals can be moved. This decision trades off logistical expediency of unrestricted translocation with the risk of reducing translocation success due to environmental mismatch between origin and translocation site conditions. In this study, we used a large dataset of 502 individually identifiable carcasses to examine the role of geographic origin and translocation distance in the relative survival of 2822 translocated subadult and adult gopher tortoises (Gopherus polyphemus), a species experiencing large‐scale mitigation translocation, at a recipient site in the Florida panhandle, USA. We hypothesized that if climate or habitat differences between the origin and translocation site influenced survival, tortoises translocated from within the Florida panhandle would have the highest survival. To the contrary, we found that survival slightly increased with increasing climatic difference between origin and recipient site, driven by higher survival of tortoises coming from central Florida sites compared to those from the panhandle and north Florida. This suggests that environmental mismatch due to long‐distance translocation is not a main driver of mortality. These models also indicated an effect of season, with a survival advantage to tortoises translocated in the spring and late fall, relative to summer translocations, and a negative effect of initial density on survival. Finally, we also estimated the upper bound on annual survival in three well‐monitored groups to be quite low (92–95%) for several years following release, suggesting caution when considering large translocated populations to be viable without first assessing adult survival. Our unexpected results highlight the importance of investigating species‐specific sensitivities to translocation distances and indicate the limitations of assumed linear effects of translocation distance on outcomes.
Rainfall variability and welfare of agricultural households: Evidence from rural Niger
Authors: Gansonré Soumaïla
Published: May 2024

Variable weather continues to be the major source of vulnerability to chronic hunger and poverty in many developing countries due to the strong dependency of livelihood strategies on rainfed farming. Quantifying the effect of climatic parameters on agricultural households is, therefore, necessary to help policymakers understand the benefits of climate policies, improve the allocation of the scarce resources dedicated to adaptation and prioritize among adaptation strategies. This article investigates the empirical relationship between the welfare of rural households and rainfall variability in the semi‐arid tropics, using household panel data and high‐resolution remotely sensed rainfall data from Niger. We find that a standard deviation increase in rainfall variability is associated with a reduction of real food consumption by 11.13%. Results also indicate that a standard deviation increase in rainfall variability reduces expenditures for cereal‐based products, animal‐based products and processed foods by 11.96%, 21.31%, and 16.23%, respectively. Our results are consistent across a battery of robustness checks. Finally, we find geographical‐based differences in terms of the effect and that access to cereal banks cushions the negative effect of rainfall variability. Policy interventions aiming at improving the well‐being of rural households should therefore emphasize improving climate adaptation strategies.

Published: May 2024

This research examined religious engagement and subsequent antibody responses to the COVID‐19 vaccine. Using publicly available data from the Understanding Society survey, we employed a longitudinal design. Between January 2016 and May 2018, respondents completed measures of religious belonging, frequency of attending religious services (i.e., extrinsic religiosity), and the difference religion made to their lives (i.e., intrinsic religiosity). A COVID‐19 survey wave was collected in March 2021 and measured antibody responses to the COVID‐19 vaccine via blood draw. A final sample of 746 adults [462 (61.9%) females, Mage = 61.94, SD = 19.07] was achieved. Mediation analyses (PROCESS, Model 4; Hayes, Introduction to mediation, moderation, and conditional process analysis: A regression‐based approach, The Guildford Press, 2022; Introduction to mediation, moderation, and conditional process analysis: A regression‐based approach; The Guildford Press) revealed one pathway through which religion and antibody responses to the COVID‐19 vaccine are associated, namely via extrinsic factors—attendance at religious services. In contrast, intrinsic religious factors which is the difference religion can make to one's life, was not a significant mediator. Overall, this analysis provides evidence that behavioural enactment of religion matters to the effectiveness of vaccination and the management of public health crises. It also highlights the value of social resources associated with engagement in valued social groups—and in particular religious social groups—for public health.

Published: May 2024

Background

This study aims to establish and validate a predictive nomogram for the short‐term clinical outcomes of myasthenia gravis (MG) patients treated with low‐dose rituximab.

Methods

We retrospectively reviewed 108 patients who received rituximab of 600 mg every 6 months in Huashan Hospital and Tangdu Hospital. Of them, 76 patients from Huashan Hospital were included in the derivation cohort to develop the predictive nomogram, which was externally validated using 32 patients from Tangdu Hospital. The clinical response is defined as a ≥ 3 points decrease in QMG score within 6 months. Both clinical and genetic characteristics were included to screen predictors via multivariate logistic regression. Discrimination and calibration were measured by the area under the receiver operating characteristic curve (AUC‐ROC) and Hosmer–Lemeshow test, respectively.

Results

Disease duration (OR = 0.987, p = 0.032), positive anti‐muscle‐specific tyrosine kinase antibodies (OR = 19.8, p = 0.007), and genotypes in FCGR2A rs1801274 (AG: OR = 0.131, p = 0.024;GG:OR = 0.037, p = 0.010) were independently associated with clinical response of post‐rituximab patients. The nomogram identified MG patients with clinical response with an AUC‐ROC (95% CI) of 0.875 (0.798–0.952) in the derivation cohort and 0.741(0.501–0.982) in the validation cohort. Hosmer–Lemeshow test showed a good calibration (derivation: Chi‐square = 3.181, p = 0.923; validation: Chi‐square = 8.098, p = 0.424).

Conclusions

The nomogram achieved an optimal prediction of short‐term outcomes in patients treated with low‐dose rituximab.
IRE1α pathway: A potential bone metabolism mediator
Authors: Yu Chengbo , Zhang Zhixiang , Xiao Li , Ai Mi , Qing Ying , Zhang Zhixing , Xu Lianyi , Yu Ollie Yiru , Cao Yingguang , Liu Yong , Song Ke
Published: May 2024

Osteoblasts and osteoclasts collaborate in bone metabolism, facilitating bone development, maintaining normal bone density and strength, and aiding in the repair of pathological damage. Endoplasmic reticulum stress (ERS) can disrupt the intracellular equilibrium between osteoclast and osteoblast, resulting in dysfunctional bone metabolism. The inositol‐requiring enzyme‐1α (IRE1α) pathway—the most conservative unfolded protein response pathway activated by ERS—is crucial in regulating cell metabolism. This involvement encompasses functions such as inflammation, autophagy, and apoptosis. Many studies have highlighted the potential roles of the IRE1α pathway in osteoblasts, chondrocytes, and osteoclasts and its implication in certain bone‐related diseases. These findings suggest that it may serve as a mediator for bone metabolism. However, relevant reviews on the role of the IRE1α pathway in bone metabolism remain unavailable. Therefore, this review aims to explore recent research that elucidated the intricate roles of the IRE1α pathway in bone metabolism, specifically in osteogenesis, chondrogenesis, osteoclastogenesis, and osteo‐immunology. The findings may provide novel insights into regulating bone metabolism and treating bone‐related diseases.

Published: May 2024

Aim

To establish the scope of the literature on modified sports interventions for children and adolescents with disabilities.

Method

For this scoping review, articles were screened and the characteristics of studies were extracted. The modified sports interventions were described in terms of their structure, using the items of the Template for Intervention Description and Replication. Components of intervention treatment were described by using the language of the Rehabilitation Treatment Specification System. Results were analysed and validated by a group of professionals, using the Public and Patient Involvement strategy.

Results

Twelve studies were eligible for inclusion, investigating interventions for children with autism spectrum disorder, cerebral palsy, and other conditions. Most studies presented a moderate level of evidence. Active ingredients were repeated sports‐related motor training and introduction to the sport through a ‘learning by action’ mechanism. The intervention target was gross motor skills performance, and intervention aims (indirect outcomes) were physical activity participation and different body functions.

Interpretation

The inclusion of stakeholders in this review helped to validate our findings about the characteristics and structure of modified sports interventions, to identify research gaps, and to provide a step process for clinical implementation. Future investigations are warranted of the effectiveness of modified sports investigations with better quality studies, including participation outcomes and studies with non‐ambulant children.

What this paper adds

Modified sports interventions target sport‐related skills performance and aim to achieve physical activity participation and body functions.

These interventions included group‐based, sports‐related motor skills training and introduction to sports in real‐world environments.

They are offered mostly for ambulant children with autism spectrum disorder and cerebral palsy.

Most studies of modified sports interventions presented moderate level of evidence.
Taking sides: Corporate social responsibility and political ideology
Authors: Gur Volkan Tibet , Tomashevskiy Andrey
Published: May 2024

In the United States and other countries, large private firms are increasingly more likely to take public political stances on controversial issues. Firms behave as ideological actors when they take sides in large public debates on social and economic issues. These stances may involve public speech, changes in the terms of service, or in internal reorganization and intrafirm actions. Despite the increase in firms' political actions, firms' ideological orientations remain unexamined. To answer this question, we collect corporate social responsibility statements from Fortune 1000 firms. Using semisupervised topic models, we identify topics that reflect stances on environmental and social issues. We then examine if firms are more likely to take stances on political issues due to pragmatic or ideological factors. We find that while pragmatic considerations play a role, firms' political stances are more driven by the ideological orientation of employees and managers. This research contributes a novel measure of firm ideology and sheds new light on the determinants of corporate political activity.

Published: May 2024

Aim

Integrated youth services (IYS) have been identified as a national priority in response to the youth mental health and substance use (MHSU) crisis in Canada. In British Columbia (BC), an IYS initiative called Foundry expanded to 11 physical centres and launched a virtual service. The aim of the study was to describe the demographics of Foundry clients and patterns of service utilization during this expansion, along with the impact of the COVID‐19 pandemic.

Methods

Data were analysed for all youth (ages 12–24) accessing both in‐person (April 27th, 2018‐March 31st, 2021) and virtual (May 1st, 2020‐March 31st, 2021) services. Cohorts containing all clients from before (April 27th, 2018‐March 16th, 2020) and during (March 17th, 2020‐March 31st, 2021) the COVID‐19 pandemic were also examined.

Results

A total of 23 749 unique youth accessed Foundry during the study period, with 110 145 services provided. Mean client age was 19.54 years (SD = 3.45) and 62% identified as female. Over 60% of youth scored ‘high’ or ‘very high’ for distress and 29% had a self‐rated mental health of ‘poor’, with similar percentages seen for all services and virtual services. These ratings stayed consistent before and during the COVID‐19 pandemic.

Conclusions

Foundry has continued to reach the target age group, with a 65% increase in number of clients during the study period compared with the pilot stage. This study highlights lessons learned and next steps to promote youth‐centred data capture practices over time within an integrated youth services context.
Prodromal questionnaire (PQ‐16) dimensionality among Colombian adolescent school students
Authors: Campo‐Arias Adalberto , Herazo Edwin , Caballero‐Domínguez Carmen Cecilia
Published: May 2024

Aims

The study aimed to determine the dimensionality of the Spanish version of the PQ‐16 among Colombian adolescent school students.

Methods

A validation study was designed with the participation of 334 Colombian adolescent students aged between 13 and 17 (M = 15.2, SD = 1.1); 171 (52.1%) were girls, and 163 (47.9%) were boys, 229 (68.6%) were ninth‐grade students and 105 (31.4%) were tenth‐grade students. Confirmatory factor analysis was performed, internal consistency was calculated with the Kuder‐Richardson and McDonald's omega tests, and correlation with suicide ideation was computed with the Kendall correlation (r).

Results

The confirmatory factor analysis showed that the PQ‐16 adequately fit a unidimensional structure: RMSEA = 0.05 (90%CI 0.04‐0.06), CFI = 0.91, TLI = 0.90, SRMR = 0.05, chi‐squared = 193.18 (df = 102, p < 0.001) and normalized chi‐squared = 1.89. This factor presented high internal consistency: Kuder‐Richardson test and McDonald's omega of 0.83. The correlation between the PQ‐16 and suicide ideation was r = 0.45 (p < 0.001).

Conclusion

The PQ‐16 is a one‐dimensional tool with high internal consistency and correlation with suicide ideation among schooled adolescents. Further research should explore the PQ‐16 performance against a structured clinical interview.
Systematic review and meta‐analysis of the visual mismatch negativity in schizophrenia
Authors: Mazer Prune , Carneiro Fábio , Domingo Juan , Pasion Rita , Silveira Celeste , Ferreira‐Santos Fernando
Published: May 2024

Mismatch negativity (MMN) is an event‐related potential component automatically elicited by events that violate predictions based on prior events. To elicit this component, researchers use stimulus repetition to induce predictions, and the MMN is obtained by subtracting the brain response to rare or unpredicted stimuli from that of frequent stimuli. Under the Predictive Processing framework, one increasingly popular interpretation of the mismatch response postulates that MMN represents a prediction error. In this context, the reduced MMN amplitude to auditory stimuli has been considered a potential biomarker of Schizophrenia, representing a reduced prediction error and the inability to update the mental model of the world based on the sensory signals. It is unclear, however, whether this amplitude reduction is specific for auditory events or if the visual MMN reveals a similar pattern in schizophrenia spectrum disorder. This review and meta‐analysis aimed to summarise the available literature on the vMMN in schizophrenia. A systematic literature search resulted in 10 eligible studies that resulted in a combined effect size of g = −.63, CI [−.86, −.41], reflecting lower vMMN amplitudes in patients. These results are in line with the findings in the auditory domain. This component offers certain advantages, such as less susceptibility to overlap with components generated by attentional demands. Future studies should use vMMN to explore abnormalities in the Predictive Processing framework in different stages and groups of the SSD and increase the knowledge in the search for biomarkers in schizophrenia.

Objective

The aim of this study was to develop a machine learning algorithm using an off‐the‐shelf digital watch, the Samsung watch (SM‐R800), and evaluate its effectiveness for the detection of generalized convulsive seizures (GCS) in persons with epilepsy.

Methods

This multisite epilepsy monitoring unit (EMU) phase 2 study included 36 adult patients. Each patient wore a Samsung watch that contained accelerometer, gyroscope, and photoplethysmographic sensors. Sixty‐eight time and frequency domain features were extracted from the sensor data and were used to train a random forest algorithm. A testing framework was developed that would better reflect the EMU setting, consisting of (1) leave‐one‐patient‐out cross‐validation (LOPO CV) on GCS patients, (2) false alarm rate (FAR) testing on nonseizure patients, and (3) “fixed‐and‐frozen” prospective testing on a prospective patient cohort. Balanced accuracy, precision, sensitivity, and FAR were used to quantify the performance of the algorithm. Seizure onsets and offsets were determined by using video‐electroencephalographic (EEG) monitoring. Feature importance was calculated as the mean decrease in Gini impurity during the LOPO CV testing.

Results

LOPO CV results showed balanced accuracy of .93 (95% confidence interval [CI] = .8–.98), precision of .68 (95% CI = .46–.85), sensitivity of .87 (95% CI = .62–.96), and FAR of .21/24 h (interquartile range [IQR] = 0–.90). Testing the algorithm on patients without seizure resulted in an FAR of .28/24 h (IQR = 0–.61). During the “fixed‐and‐frozen” prospective testing, two patients had three GCS, which were detected by the algorithm, while generating an FAR of .25/24 h (IQR = 0–.89). Feature importance showed that heart rate‐based features outperformed accelerometer/gyroscope‐based features.

Significance

Commercially available wearable digital watches that reliably detect GCS, with minimum false alarm rates, may overcome usage adoption and other limitations of custom‐built devices. Contingent on the outcomes of a prospective phase 3 study, such devices have the potential to provide non‐EEG‐based seizure surveillance and forecasting in the clinical setting.

Because of its involvement in breathing control and neuronal excitability, dysregulation of the serotonin (5‐HT) 2C receptor (5‐HT2C) might play a key role in sudden unexpected death in epilepsy. Seizure‐induced respiratory arrest is thus prevented by a 5‐HT2B/C agonist in different seizure model. However, the specific contribution of 5‐HT2C in chronic epilepsy‐related respiratory dysfunction remains unknown. In a rat model of temporal lobe epilepsy (EPI rats), in which we previously reported interictal respiratory dysfunctions and a reduction of brainstem 5‐HT tone, quantitative reverse transcriptase polymerase chain reaction showed overexpression of TPH2 (5‐HT synthesis enzyme), SERT (5‐HT reuptake transporter), and 5‐HT2C transcript levels in the brainstem of EPI rats, and of RNA‐specific adenosine deaminase (ADAR1, ADAR2) involved in the production of 5‐HT2C isoforms. Interictal ventilation was assessed with whole‐body plethysmography before and 2 h after administration of SB242084 (2 mg/kg), a specific antagonist of 5‐HT2C. As expected, SB242084 administration induced a progressive decrease in ventilatory parameters and an alteration of breathing stability in both control and EPI rats. However, the size of the SB242084 effect was lower in EPI rats than in controls. Increased 5‐HT2C gene expression in the brainstem of EPI rats could be part of a compensatory mechanism against epilepsy‐related low 5‐HT tone and expression of 5‐HT2C isoforms for which 5‐HT affinity might be lower.

Data‐driven fatigue strength predictions are gaining popularity. Nevertheless, many machine learning models lack trustworthiness due to their limited decision‐making transparency which often hinders their practical application. In this investigation, we assess the expressiveness of the model‐agnostic explainable AI method known as SHapley Additive exPlanations (SHAP) for data‐driven fatigue strength prediction. Our study demonstrates that the SHAP feature sensitivity analysis underpins known physical relations from materials processing and fatigue theory. This even applies in view of the high‐dimensional, cross‐correlated fatigue feature space and despite data heterogeneity (different steels, component designs, and loads). For instance, SHAP indicates a fatigue strength increase with higher solid solution‐strengthening element concentrations, such as chromium and nickel. SHAP identifies correlations rather than causality. Thus, data science and domain knowledge should be closely linked during the SHAP assessment. If this is satisfied, plausible causal relations can be inferred, and spurious ones arising from confounding variables can be discarded.

Published: May 2024

In the present work, the influence of defects on the compressive response of octet‐truss AlSi10Mg lattice structure specimens produced with a selective laser melting process is investigated. The defect population in one cell, in two cells, and cubic specimens composed of 27 cells has been assessed with micro‐computed tomography (micro‐CT) analyses. The statistical distributions of the characteristic defect sizes, i.e., the equivalent diameter, the volume, and the surface, assessed in the lattice structure specimens and in volumes randomly extracted from a rectangular bar have been compared. Finally, the compressive behavior of lattice structure specimens has been simulated with a simplified damage‐tolerant finite element model accounting for the influence of defects and compared with experimental results. The analyses have proven that the defect population in volumes extracted from a rectangular bar can provide reliable simulated results, even if micro‐CT inspections of a unit cell or specimens made of several cells are suggested.

The pyramid lattice sandwich structure, characterized by high load‐bearing capacity, lightweight nature, and fully open internal space, is considered an extremely promising super‐strong structure. Stereolithography technology was utilized to achieve the monolithic formation of single‐layer multi‐cell pyramidal lattice sandwich structures. Quasi‐static compression tests and finite element simulations were conducted to characterize the compressive properties and failure modes. Results indicate that the compressive strength, compressive modulus, specific strength, and specific stiffness of the single‐layer multi‐cell pyramidal lattice sandwich structure increase as the relative density increases. Moreover, fracture failure was observed in the structures with various relative densities. Additionally, the compressive failure of multi‐layer density gradient pyramidal lattice sandwich structures was investigated. Experimental and numerical findings indicate that the optimal density gradient scheme for the ZCMLG structure is I‐III‐II, resulting in a peak compression force that is 342.14% and 288.55% higher than that of the ZAMLG and ZBMLG structures, respectively.
