AbstractAimsThe purpose of this study was to investigate the status of self‐management behaviour and illness perceptions and to examine illness perceptions in relation to self‐management behaviour in elderly patients with chronic obstructive pulmonary disease (COPD).MethodsA cross‐sectional study was conducted, and 152 elderly COPD patients were recruited via the convenience sampling method. The COPD Self‐Management Scale and the Revised Illness Perception Questionnaire for COPD patients were used to examine self‐management behaviour and illness perceptions. Pearson correlation analysis, univariate analysis and hierarchical linear regression analysis were used to explore illness perceptions in relation to self‐management behaviour.ResultsThe mean overall score for self‐management behaviour was 2.90 ± 0.39. Among the subscales of self‐management behaviour, information management had the lowest score of 2.20 ± 0.76. Patients' demographic and clinical characteristics, including educational level, smoking status, type of primary caregiver, home oxygen therapy and COPD duration, were found to be significant determinants of self‐management behaviour. After controlling for these variables, several illness perception subscales, including treatment control, personal control, coherence, timeline cyclical and identity, were significantly correlated with self‐management behaviour.ConclusionsThis study confirmed that elderly COPD patients' self‐management behaviour was unsatisfactory and that illness perceptions were significant determinants of self‐management behaviour. The findings may contribute to the development of self‐management interventions for elderly COPD patients.

AbstractSuicide management skills are essential for nursing students, as they are often the initial healthcare contact for individuals at risk of suicide. Recognising signs of suicidal ideation and behaviour is critical for initiating timely interventions. This study aimed to develop and access the psychometric evaluation of the Suicide Management Competency Scale (SMCS) for nursing students. A first draft of the SMCS was initially developed following literature and focus group, and a scale containing 28 items was constructed. We recruited 216 participants from two nursing schools. Construct validity was evaluated with exploratory factor analysis (EFA). Internal consistency reliability was determined with Cronbach's alpha, and test–retest reliability was examined with intra‐class correlation. After four rounds of EFA and item analysis, we reduced the number of items to 16. We deleted 12 items, including 4 items for communalities less than 0.40, 3 items for cross‐loading, 3 items for factor loading less than 0.40, and 2 items for low corrected item–total correlation. The final 16‐item SMCS resulted in three subscales, which explained 55.813% of the total variance: emotional challenges in suicide risk assessment, delivering suicide interventions, and suicide risk nursing competence and confidence. Cronbach's alpha was 0.854 for the total score and 0.748 to 0.847 for the subscales. The newly developed SMCS was found to have good reliability and validity, suggesting that this scale could be used to evaluate nursing students' perceived competency in managing suicide, which might help cultivate competence in nurses' ability to effectively manage and prevent suicide, thus contributing to saving lives.

AbstractBackgroundThe measurement of internal states of people with an intellectual disability is challenging. Given these difficulties, proxy respondents are sometimes used. However, the literature provides some caution about the validity of the use of proxy respondents.AimsThis review aims to identify the available evidence regarding the use of proxy respondents in the measurement of internal states of people with intellectual disabilities.MethodThe Arksey and O'Malley scoping review framework was used for this review, refined with the Joanna Briggs Institute Methodology.ResultsResults indicate there are some differences in the findings reported with respect to the efficacy of the use of proxy respondents. These may be due to a number of inconsistencies and weaknesses in examinations of their utility.ConclusionsIf proxy‐reports are to be useful in understanding the internal states of people with intellectual disability, researchers need to address the shortcomings revealed by this review.
“Theory will take you only so far” (Nolan, 2023): In search of greater insight through quantitative, observation‐based research

AbstractTheories developed for understanding the general management or economic phenomena are increasingly ineffective for explaining logistics/SCM‐specific phenomena, despite the best efforts of LSCM researchers to utilize them for those purposes. Unfortunately, the hierarchies and infrastructure in place to ensure LSCM research is theoretically grounded and conducted with scholarly rigor have not advanced to a point where the use of alternative methods to explore such questions is common. The key objective of this paper is to guide where empirical LSCM research could evolve if it took its relationship with theory a step further. Our thesis is that inductive research using empirical data can yield additional insightful answers to relevant questions. We hope that discussion of these topics from a 2024 perspective can spur more research that uses empirical analysis as a starting point to create new theory in LSCM and, importantly, to persuade members working in our field to respect and accept rigorous empirical research conducted outside the traditional deductive, logical positivist paradigm.

AbstractAimThe oral microenvironment contributes to microbial composition and immune equilibrium. It is considered to be influenced by dietary habits. Phenylketonuria (PKU) patients, who follow a lifelong low‐protein diet, exhibit higher prevalence of oral diseases such as periodontitis, offering a suitable model to explore the interplay between diet, oral microbiota and oral health.Materials and MethodsWe conducted 16S rDNA sequencing on saliva and subgingival plaque from 109 PKU patients (ages 6–68 years) and 114 age‐matched controls and correlated oral microbial composition and dental health.ResultsPKU patients exhibited worse dental health, reduced oral microbial diversity and a difference in the abundance of specific taxa, especially Actinobacteriota species, compared to controls. PKU patients with poor periodontal health exhibited higher alpha diversity than the orally healthy ones, marked by high abundance of the genus Tannerella. Notably, the observed taxonomic differences in PKU patients with normal indices of decayed/missing/filled teeth, plaque control record, gingival bleeding index and periodontal screening and recording index generally differed from microbial signatures of periodontitis.ConclusionsPKU patients' reduced microbial diversity may be due to their diet's metabolic challenges disrupting microbial and immune balance, thus increasing oral inflammation. Higher alpha diversity in PKU patients with oral inflammation is likely related to expanded microbial niches.
The role of existing shareholders in private equity placements in China

Published: May 2024

AbstractIn this article, we investigate how the participation of firms’ existing shareholders affects the pricing and valuation of private investments in public equity (PIPEs). Using a large sample of PIPEs issued by Chinese listed firms from 2006 to 2019, we find that the effective discount and long‐term buy‐and‐hold abnormal stock returns of PIPEs with existing shareholder participation are significantly higher than those with only new investor participation, after controlling for heterogeneous types of PIPE investors. However, the superior post‐PIPE stock performance of deals with existing shareholders is not driven by improved operating performance but by tunneling activities such as frequent dividend announcements, related‐party transactions, and positive earnings management during the lock‐up period. Our findings suggest that the effect of existing shareholders’ participation in private equity placements is more consistent with the tunneling hypothesis than the certification hypothesis. We document that the tunneling incentives are stronger when firms face greater financial constraints and can be mitigated when the firm's corporate governance is stronger.

Published: May 2024

AbstractFrom 2000 to 2022, all and serious notifications of the EU Rapid Alert System for Food and Feed (RASFF) on herbs and spices were examined to identify the most notified products, their associated hazards and origin countries, as well as the consequent notification classification and actions taken. The data reveals that 3741 notifications were transmitted for herbs and spices during the last 23 years, accounting for 5.3% of the RASFF total notifications of all product categories (70630). Border rejection and serious risk decisions represented 37.9% and 39.5% of the total herbs and spices notifications, respectively. In the last 5 years, serious notifications ranged from 76.6% to 87.2% of all herbs and spices notifications. India was the most notified origin country (23.6%), followed by Brazil (8.7%), Thailand (7.2%), Turkey (5.8%), and China (4.6%). The top 10 notified herbs and spices were chili, black pepper, curry, paprika, nutmeg, spice mix, basil, mint, ginger, and cumin, while the top 10 hazards were Salmonella, aflatoxin, Sudan 1, Sudan 4, ethylene oxide (EtO), ochratoxin A, chlorpyrifos, Escherichia coli, pyrrolizidine alkaloids, and color E 160b. Approximately 96.3% of black pepper, 71% of chili, and almost all nutmeg serious notifications were related to Salmonella, aflatoxins, and mycotoxins, respectively. Strict measures to minimize the risk associated with such contaminants in herbs and spices must be implemented.
When Does a Firm Fail to Walk the Talk? Decoupling in International Expansion

Published: May 2024

AbstractNeo‐institutional theory predicts that when adaptations to institutional pressures contradict a firm's efficiency needs, decoupling may arise. This study systematically investigates the drivers of heterogeneous decoupling in the context of international expansion. We propose that specific configurations – awareness of peers’ decoupling, a strong motivation to obtain legitimacy through ceremonial conformity, and a weak capability to couple stated policies with practices – will lead to a high occurrence of decoupling. An empirical analysis of 8918 annual reports of 1974 Chinese‐listed companies from the period 2013–17 suggests that the ‘Go Global’ initiative undertaken by the Chinese government has created high institutional pressure for all Chinese firms to expand globally. However, when the implementation of that move is perceived as too costly or risky for a firm, the firm is likely to choose to decouple its international expansion from its stated commitment to expand under certain configurations of awareness, motivation, and capability conditions. Our theory and empirical findings extend decoupling research and international business research by providing a holistic configurational analysis of firms’ decoupling in an international expansion context.

AbstractThe objective of this research was to compare the sensory and cognitive performance of generations of consumers using artisanal tortillas. Four groups of generational consumers were evaluated (baby boomers, generation X, Y, and Z; n = 100 consumers per generational group). Three experiments were conducted: (1) use of the intensity scale, (2) determination of dominant attributes via TDS and (3) elicited emotions and memories. The results of the first experiment showed that baby boomers, generation X and Y had the best performance in terms of discrimination and consensus. The second experiment demonstrated that generation Z consumers identified dominant attributes of texture in mouth and the other generations identified corn flavor, nixtamal flavor, and sour taste attributes as dominant. Regarding the evaluation of emotions and memories, it was observed that as generations progress, more emotions, and memories were used. In this sense, generation Z was the one that used the most negative emotions and memories.Practical ApplicationsAnalyzing the generational effect can help researchers and tortilla manufacturers to the selection of generational consumer for the evaluation of artisanal, cross‐cultural, or industrialized foods.

AbstractEndothelial‐to‐mesenchymal transition (EndMT) is a complex biological process of cellular transdifferentiation by which endothelial cells (ECs) lose their characteristics and acquire mesenchymal properties, leading to cardiovascular remodeling and complications in the adult cardiovascular diseases environment. Melatonin is involved in numerous physiological and pathological processes, including aging, and has anti‐inflammatory and antioxidant activities. This molecule is an effective therapeutic candidate for preventing oxidative stress, regulating endothelial function, and maintaining the EndMT balance to provide cardiovascular protection. Although recent studies have documented improved cardiac function by melatonin, the mechanism of action of melatonin on EndMT remains unclear. The present study investigated the effects of melatonin on induced EndMT by transforming growth factor‐β2/interleukin‐1β in both in vivo and in vitro models. The results revealed that melatonin reduced the migratory ability and reactive oxygen species levels of the cells and ameliorated mitochondrial dysfunction in vitro. Our findings indicate that melatonin prevents endothelial dysfunction and inhibits EndMT by activating related pathways, including nuclear factor kappa B and Smad. We also demonstrated that this molecule plays a crucial role in restoring cardiac function by regulating the EndMT process in the ischemic myocardial condition, both in vessel organoids and myocardial infarction (MI) animal models. In conclusion, melatonin is a promising agent that attenuates EC dysfunction and ameliorates cardiac damage compromising the EndMT process after MI.
Solid as a rock: The main drivers of changes in natural, rocky plant communities

Published: May 2024

AbstractQuestionChanges caused by climate warming and nitrogen pollution are observed in forest, grassland and alpine ecosystems worldwide. However, still little is known about the impact of these globally influencing factors on natural rocky plant communities. Has species composition of natural rocky communities changed over time? What is the role of large‐scale and fine‐scale environmental factors in shaping the compositional, functional and habitat patterns in studied plant communities over time?LocationSudetes Mountains, southwestern Poland.MethodsWe used 214 pairs of replots (collected between 1989 and 2022) of rocky plant communities, with a mean timespan of 14.2 years. The changes in species composition, environmental conditions and functional traits were analysed using ordination techniques and generalised additive models (GAMs) and with reference to large‐scale factors (mean maximum temperatures, actual evapotranspiration, N deposition) and fine‐scale factors (light availability, bedrock type, initial site conditions) for each locality.ResultsSpecies composition of the studied communities has not changed significantly over time. Only for 11 out of 258 species, statistically significant increases (from 2% to 8%) in their proportion were recorded. The changes in environmental conditions were significantly influenced mainly by fine‐scale factors such as changes in light availability and baseline site conditions. Plots that were initially less thermophilic or nitrophilic showed stronger signals of thermophilisation and eutrophication in the resurvey. The influence of large‐scale factors was considerably less pronounced. Similarly, the key role in explaining changes in plant traits for the data set under study falls to local factors, particularly changes in light availability.ConclusionsOur study confirms the validity of considering both large‐ and fine‐scale factors as well as initial site conditions in research on long‐term changes in plant communities. Rocky plant communities respond to global changes in a different way than other types of phytocoenose, showing high stability of species composition and functional traits over time.
Effects of growing season and individual growth rates on the occurrence of larval overwintering in Otton frog tadpoles
Authors: Iwai N. 
Published: May 2024

AbstractThe timing and size of metamorphosis are crucial for the future fitness of organisms with complex life cycles, such as amphibians. In some amphibian species, a portion of tadpoles will metamorphose in their natal year whereas others from the same cohort overwinter as tadpoles. Low temperature and food availability were previously assumed to be the underlying reasons; however, the factors influencing the decision to overwinter as tadpoles or metamorphose in the natal year have not been extensively studied. This study investigated these factors by conducting laboratory‐rearing experiments on Babina subaspera tadpoles. The tadpoles were individually reared under controlled temperature and light conditions that simulated five different growing seasons (i.e., the start month) observed in the field. Four different food quantity levels were set to induce different growth rates, which were measured individually. The results revealed that 33 tadpoles metamorphosed within their natal year, whereas 52 tadpoles were overwintered as tadpoles and metamorphosed the following spring. The size at metamorphosis was larger in tadpoles that metamorphosed after winter than in those that metamorphosed before winter. Whether tadpoles metamorphosed before or after winter was influenced by the individual growth rate and growing season. Tadpoles with slower growth rates were more likely to metamorphose after winter, possibly because slower growth prevented them from reaching the critical size threshold required for metamorphosis before winter. The threshold for the occurrence of larval overwintering varied with the growing season; tadpoles that spawned later in the year were more likely to overwinter, even with a high growth rate. The results suggested that slow‐growing B. subaspera tadpoles with insufficient time until the onset of winter would gain a higher fitness by metamorphosing after winter. This would be advantageous due to the tadpoles' potentially high survival rate during dormancy as well as their larger size at metamorphosis in the following year.

AbstractRegolith samples returned from asteroid 162173 Ryugu by the Hayabusa2 mission provide direct means to study how space weathering operates on the surfaces of hydrous asteroids. The mechanisms of space weathering, its effects on mineral surfaces, and the characteristic time scales on which alteration occurs are central to understanding the spectroscopic properties and the taxonomy of asteroids in the solar system. Here, we investigate the behavior of the iron monosulfides mineral pyrrhotite (Fe1−xS) at the earliest stages of space weathering. Using electron microscopy methods, we identified a partially exposed pyrrhotite crystal that morphologically shows evidence for mass loss due to exposure to solar wind ion irradiation. We find that crystallographic changes to the pyrrhotite can be related to sulfur loss from its space‐exposed surface and the diffusive redistribution of resulting excess iron into the interior of the crystal. Diffusion profiles allow us to estimate an order of magnitude of the exposure time of a few thousand years consistent with previous estimates of space exposure. During this interval, the adjacent phyllosilicates did not acquire discernable damage, suggesting that they are less susceptible to alteration by ion irradiation than pyrrhotite.
