AbstractIndividuals in the early stages of dementia often endure elevated levels of stress and anxiety, which can hinder their ability to adapt to the progression of dementia. To mitigate the negative impacts of dementia more effectively, it is necessary to explore the trajectory of the adaptation process of persons living with dementia. This study aimed to construct a theoretical framework for the adaptation process of individuals in the early stages of dementia. Participants were dyads of persons diagnosed with mild dementia or mild cognitive impairment (≥ 60 years of age) and their primary family caregivers. This longitudinal study used a grounded theory approach to explore the adaptation trajectory changes in persons with mild dementia over a 3‐year period. Data were collected from dyads with face‐to‐face interviews. Analysis of the interview data revealed the core category was ‘Coexisting with anomie: Progressive disappointment and striving’, which was comprised of three categories: awareness of alienation, unsettled feelings, and restorative avoidance coping. Categories changed depending on levels of cognition and constituted progressive and cyclical dynamic processes. Four contextual factors positively or negatively influenced adaptation: level of insight about dementia, personal traits, caregiving style of the caregiver, and level of social interactions. These findings provide a new perspective about the mental health of persons in early‐stage dementia. Understanding coexisting with anomie and related influencing factors could facilitate the development of support interventions by mental health nursing staff, which could improve emotional safety, promote psychological well‐being, and increase quality of life for persons living with dementia.

AbstractBackgroundThe emergence of the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS‐CoV‐2) in early 2020 and subsequent implementation of public health and social measures (PHSM) disrupted the epidemiology of respiratory viruses. This work describes the epidemiology of respiratory syncytial virus (RSV) observed during two winter seasons (weeks 40–20) and inter‐seasonal periods (weeks 21–39) during the pandemic between October 2020 and September 2022.MethodsUsing data submitted to The European Surveillance System (TESSy) by countries or territories in the World Health Organization (WHO) European Region between weeks 40/2020 and 39/2022, we aggregated country‐specific weekly RSV counts of sentinel, non‐sentinel and Severe Acute Respiratory Infection (SARI) surveillance specimens and calculated percentage positivity. Results for both 2020/21 and 2021/22 seasons and inter‐seasons were compared with pre‐pandemic 2016/17 to 2019/20 seasons and inter‐seasons.ResultsAlthough more specimens were tested than in pre‐COVID‐19 pandemic seasons, very few RSV detections were reported during the 2020/21 season in all surveillance systems. During the 2021 inter‐season, a gradual increase in detections was observed in all systems. In 2021/22, all systems saw early peaks of RSV infection, and during the 2022 inter‐seasonal period, patterns of detections were closer to those seen before the COVID‐19 pandemic.ConclusionRSV surveillance continued throughout the COVID‐19 pandemic, with an initial reduction in transmission, followed by very high and out‐of‐season RSV circulation (summer 2021) and then an early start of the 2021/22 season. As of the 2022/23 season, RSV circulation had not yet normalised.
To innovate or not? The optimal innovation strategy choice in a supply chain—from the perspective of the leading supplier
Authors: Qian Qian , Liu Lijun , Yang Yang 
Published: November 2023

AbstractInnovation plays a critical role in shaping market advantages and leading technology competition. Meanwhile, innovations have spillover effects that are beneficial to others, even though they are not involved in the practice of innovation. Innovation is full of uncertainty, which means investment is not guaranteed to pay off for innovators. Therefore, it is essential to choose the appropriate innovation strategy, especially for those leading firms with both innovative ability and bargaining power. In this paper, both uncertainty (including technical uncertainty and market uncertainty) and spillover effect are taken into consideration to explore the innovation strategies adopted by leading firms: non‐innovation, independent innovation, and collaborative innovation (i.e., co‐innovation hereafter). Furthermore, numerical analysis is conducted to explore the integration strategy that a leading firm adopts to control one of the manufacturers. The results are obtained as follows. First, the innovation of a leading supplier is always beneficial to the whole supply chain. Second, the spillover effect of co‐innovation is more significant, compared to other innovation strategies. Last, from the perspectives of profit and innovation efficiency across the supply chain, co‐innovation is the best option for a leading firm.
The effectiveness of nursing interventions in adherence to self‐care for preventing venous ulcer recurrence: A systematic literature review
Authors: Gomes Filipe José Paulo , Henriques Maria Adriana Pereira , Baixinho Cristina Lavareda 
Published: November 2023

AbstractVenous ulcers affect up to 3% of the global population, with a high impact on economies and quality of life. This is exacerbated by its recurrence rates, which reach 70% at 12 months after healing. The perpetuation of these cycles of healing and recurrence is not interrupted or even attenuated by the self‐care activities recommended and directed toward their prevention. In this context, we sought to identify the effectiveness of interventions that promote adherence to self‐care to prevent venous ulcer recurrence. In August 2022, we conducted a literature search via EBSCO in the following databases: CINAHL Complete, MEDLINE Complete, Cochrane Database of Systematic Reviews, Scopus, and Web of Science. The inclusion criteria were researched in the form of randomised controlled trials or systematic literature reviews, and 99 studies were identified. During the different times of selection, four studies met the defined inclusion criteria and were included. As the main conclusions, the emphasis goes to the importance of the use of compression and the greater effectiveness of higher compression classes for the prevention of recurrence. Different educational methodologies seem to be important to increase knowledge about prevention, specifically regarding the aetiology of recurrence and the implementation of prevention measures.

AbstractNear‐infrared (NIR) broadband emitting phosphors regarded as ideal miniaturized NIR light sources, have recently received considerable attention. Nevertheless, the lack of appropriate substitutes for poisonous Cr3+ still poses a significant obstacle. Here, by selecting double perovskite‐type antimonates compound Ca2LuSbO6 (CLSO) and Ca2YSbO6 (CYSO) as the hosts, the broadband NIR‐emitting CLSO: 0.008Fe3+ and CYSO: 0.01Fe3+ phosphors are firstly reported. The above materials exhibit a rare long‐wavelength NIR emission band peaking at 927 and 938 nm, respectively. Accordingly, their full widths at half maximum are 128 and 135 nm, respectively. Moreover, the mechanism of their concentration quenching and thermal quenching effect are discussed. The IQEs of CLSO: 0.008Fe3+ is measured to be 69%, which is superior to many available Fe‐activated phosphors. Integrating the bond valence theory analysis with electron paramagnetic resonance measurement, Fe3+ only substitutes the lattice site of the Sb atom to generate a [FeO6] octahedron accompanying lattice distortion. Significantly, the as‐fabricated phosphor‐converted light emitting diodes device shows substantial applications in night vision and NIR spectroscopy detection. This work contributes to novel insights into the photoluminescence and site occupancy of Fe3+, thereby paving a new avenue for exploring next‐generation environmentally‐friendly and nontoxic NIR light‐emitting materials.

AbstractAim(s)To understand the experiences of HIV nurses in the context of ambivalence between biomedical treatment advancements and the continuing burden for people living with HIV and negative representations of HIV.DesignAn interpretative phenomenological study was conducted using in‐depth interviews.MethodsTwenty‐one interviews with nurses were conducted between November 2021 and March 2022. A thematic analysis was performed.ResultsSix themes related to the nurses' experiences emerged. Despite effective treatment for most people with HIV, nurses identify patient populations that require additional care. Nurses are flexible in making extra appointments to accommodate complex issues in these patients. Nurses develop a unique relationship with their patients based on trust and empathy, linked to patient's experiences with stigma and discrimination for people with HIV. Nurses perceive their tasks as becoming increasingly complex. There is explicit awareness about the changes in HIV care from acute to chronic care and how this affects nurses' tasks. Nurses continue to differentiate HIV from other chronic conditions.ConclusionBiomedical advancements change the organization of HIV care while public health concerns remain and patient population has particular needs due to negative social representations of HIV. Nurses navigate these issues in their everyday care.Implications for the Profession and/or Patient CareA potential re‐evaluation of the role of nurses in providing chronic HIV care.ImpactOur study addresses the roles of HIV nurses as care is shifting towards chronic care models. The unique relationship between nurses and patients is key in understanding the importance of nurses in the care trajectory.

Published: November 2023

AbstractAimNatural disturbances are key drivers of forest ecosystem dynamics and are highly sensitive to global change. Despite their importance, central disturbance characteristics remain unknown for many forests worldwide. Here, we quantified an important component of the forest disturbance regime—the distribution of patch sizes—in strictly protected areas by asking: (i) How are patch sizes of naturally occurring disturbances distributed across the Alps and how can they best be quantified? (ii) Are patch size distributions stochastic or can they be explained by environmental drivers? (iii) What are the return periods of extreme disturbance events?LocationEuropean Alps.MethodsWe analysed satellite‐based disturbance maps for the period 1986–2020 across a network of 12 strictly protected areas, modelling patch sizes of all observed disturbance patches as well as of annual extreme events. We tested the influence of temperature, precipitation, topographic complexity and forest type on patch size distributions.ResultsDisturbance patch sizes across the Alps (median 0.36 ha, 5th percentile 0.18 ha and 95th percentile 1.71 ha) as well as their annual extremes (0.72 ha, 0.18–7.11 ha) are best described by a Fréchet distribution. The size of annual extreme events significantly increased with intra‐annual temperature amplitude (+0.98 ha with a one standard deviation increase) and the share of evergreen trees (+0.63 ha). On average, disturbance patches of 5.5 ha (95% credible interval 2.6–17.5 ha) occur once every 30 years, whereas patches of 2.6 ha (1.2–7.0 ha) occur once every 10 years.Main ConclusionsDisturbances caused by natural agents are generally small and stochastic across the Alps. Extreme events are driven by climate, suggesting sensitivity of disturbance patch sizes to climate change. Our results provide a baseline for monitoring climate‐induced changes in forest disturbance regimes, and provide important information for the management and conservation of forest ecosystems.
Untying the Gordian knot: A systematic review and integrative framework of supply network complexity
Authors: Ateş Melek Akın , Luzzini Davide 
Published: November 2023

AbstractThe escalating complexity of supply networks is undeniable, and organizations grapple with myriad globally dispersed suppliers spanning diverse industries and operating amid volatility and uncertainty while having multifaceted interactions. In line with this, scholars have been investigating supply network complexity (SNC) for over two decades, yet the domain is not converging; definitions and operationalizations are varied, a multiplicity of theoretical perspectives exists, performance implications are inconclusive, and supply chain managers are certainly still struggling with the complexity of their supply networks. To address this critical gap, we conducted a rigorous systematic review of 116 articles and synthesized the extant research in a comprehensive nomological network of SNC. Our synthesis encompasses the following key aspects: (i) defining (sub)dimensions of SNC by reconciling diverse conceptualizations, (ii) elaborating on the direct and contingent effects of SNC by highlighting underlying mechanisms and relevant theories, (iii) identifying antecedents of SNC, and (iv) introducing a detailed categorization of SNC management practices and illustrating SNC management capability as an antecedent of such practices. We conclude by presenting an extensive research agenda illustrating the gaps in the literature and charting a path forward in relation to different themes, theories, and methods.
Supply chain visibility types and contextual characteristics: A literature‐based synthesis
Authors: Swink Morgan , Sant’Ana Gallo Igor , Defee Cliff , da Silva Andrea Lago 
Published: November 2023

AbstractExisting literature offers multiple interpretations of how managers might develop and deploy supply chain visibility (SCV). However, current visibility research lacks rigorous definitions of visibility types and their relationships to contextual factors. Our systematic literature review and analysis extends previous studies by identifying visibility objects, potentially important contextual characteristics, and their interrelationships. We highlight research trends and develop a framework that links types of visibility to relational, environmental, and operational characteristics that either support visibility development or moderate its value for a firm. In addition, we offer a synthesis and critique of research questions, theoretical perspectives, and methods researchers have used to address SCV concepts and relationships. The review findings suggest rich opportunities for future research.
Sales‐based compensation and collusion with heterogeneous firms
Authors: Lee Jeongwoo , Turner Douglas C. 
Published: November 2023

AbstractPricing and output decisions are often delegated to managers compensated on the basis of sales. Prior literature has shown that when firms are homogeneous, the delegation of pricing or output decisions to managers, compensated on the basis of sales, does not facilitate collusion. We show that when firms are heterogeneous, either in marginal cost or product quality, sales‐based compensation can facilitate collusion under both price and quantity competition. As a result, compensating managers on the basis of sales can increase firm profits and reduce consumer welfare. Additionally, we find that owners can strategically design managerial compensation structures to incentivize collusion between rival managers.
Use of trophic ecology of omnivorous fish and abiotic factors as supporting tools for assessing environmental impacts in a neotropical river

Published: November 2023

AbstractThe study of diet is one of the mechanisms by which competition for resources between species that cohabit in the same ecosystem can be inferred. Therefore, the relationships of the indices that measure specialization in the diet of fish species are necessary to characterize the nutritional quality of these populations and the ecosystem's environmental health. Three species of catfish were selected: one invasive (Clarias gariepinus) and two natives (Trachelyopterus striatulus and Rhamdia quelen), with similar distribution along the Guapi‐Macacu River, in the Guapimirim Protection Area (Rio de Janeiro). Fifty‐nine catfish of the three species were collected in total, along 32 collection points in the Guapi‐Macacu River in two periods (dry and rainy) in 2018. Non‐parametric statistics showed the partition of resources between species and the influence of abiotic factors (temperature, pH, transparency, and dissolved oxygen) contributing to the selection of available resources in the environment. Diet‐related indices—repletion index (RI), condition factor (K), niche width, and trophic position (TP) of the specimens collected—contributed to measuring the nutritional status of each of these catfish species, showing that R. quelen has a relationship between RI and K, tending to absorb and metabolize nutrients faster than other species. In addition, the invasive species occupies a wide range of TPs compared to native species, confirming its feeding plasticity. On the contrary, T. striatulus needs large amounts of terrestrial insects to maintain its poor condition factor. Also, the RI showed direct influences of abiotic variables, with the temperature being the most prominent. Our results suggest that the invasive species can benefit from this environment that shows signs of environmental degradation.
Escaping malnutrition by shifting habitats: A driver of three‐spined stickleback invasion in Lake Constance

Published: November 2023

AbstractFatty acids, and especially long‐chain polyunsaturated fatty acids, are biologically important components in the metabolism of vertebrates, including fish. Essential fatty acids (EFA) are those that in a given animal cannot be synthesized or modified from precursors and must therefore be acquired via the diet. Because EFAs are often unevenly distributed in nature, this requirement may drive species to make behavioral or ecological adaptations to avoid malnutrition. This is especially true for fish like the three‐spined stickleback (Gasterosteus aculeatus L.) of Upper Lake Constance (ULC), whose recent marine ancestors evolved with access to EFA‐rich prey, but which found themselves in an EFA‐deficient habitat. An unexpected and unprecedented ecological shift in the ULC stickleback population from the littoral to pelagic zones in 2012 might be linked to EFA availability, triggering ecological release and enabling them to build a hyperabundant population while displacing the former keystone species, the pelagic whitefish Coregonus wartmanni. To test this hypothesis, sticklebacks from the littoral and pelagic zones of ULC were sampled seasonally in two consecutive years, and their stomach contents and fatty acid profiles were analysed. Pelagic sticklebacks were found to possess significantly higher values of an important EFA, docosahexaenoic acid (DHA), especially during autumn. Evaluation of the DHA supply suggests that sticklebacks feeding in the littoral zone during autumn could not meet their DHA requirement, whereas DHA availability in the pelagic zone was surplus to demand. During autumn, pelagic sticklebacks consumed large amounts of DHA‐rich prey, that is, copepods, whereas littoral sticklebacks relied mainly mostly on cladocerans, which provide much lower quantities of DHA. Access to pelagic zooplankton in 2012 was possibly facilitated by low densities of previously dominant zooplanktivorous whitefish. The present study offers a convincing physiological explanation for the observed expansion of invasive sticklebacks from the littoral to the pelagic zones of Lake Constance, contributing to a phase shift with severe consequences for fisheries.
CTmax in brook trout (Salvelinus fontinalis) embryos shows an acclimation response to developmental temperatures but is more variable than in later life stages

AbstractCritical thermal maximum (CTmax) is widely used to measure upper thermal tolerance in fish but is rarely examined in embryos. Upper thermal limits generally depend on an individual's thermal history, which molds plasticity. We examined how thermal acclimation affects thermal tolerance of brook trout (Salvelinus fontinalis) embryos using a novel method to assess CTmax in embryos incubated under three thermal regimes. Warm acclimation was associated with an increase in embryonic upper thermal tolerance. However, CTmax variability was markedly higher than is typical for juvenile or adult salmonids.

Published: November 2023

AbstractBesides COVID‐19, two of the most critical outbreaks of our day are insulin resistance, type 2 diabetes mellitus (T2DM), and Alzheimer's disease (AD). Each disease's pathophysiology is well established. Furthermore, a substantial overlap between them has coexisted. Uncertainty remains on whether T2DM and AD are parallel illnesses with the same origin or separate illnesses linked through violent pathways. The current study was aimed at testing whether the insulin resistance in the brain results in AD symptoms or not. Insulin resistance was induced in the brains of rats using a single intracerebroventricular streptozotocin (STZ) dose. We then measured glucose, insulin receptor substrate 2 (IRS‐2), amyloid β (Aβ) deposition, and tau phosphorylation in the brain to look for signs of insulin resistance and AD. The results of this study indicated that a single dose of STZ was able to induce insulin resistance in the brain and significantly decline IRS‐2. This resistance was accompanied by obvious memory loss, Aβ deposition, and tau phosphorylation, further visible diminishing in neurotransmitters such as dopamine and acetylcholine. Furthermore, oxidative stress was increased due to the antioxidant system being compromised. Interestingly, the pancreas injury and peripheral insulin resistance coexisted with brain insulin resistance. Indeed, the antidiabetic metformin was able to enhance all these drastic effects. In conclusion, brain insulin resistance could lead to AD and vice versa. These are highly linked syndromes that could influence peripheral organs. Further studies are required to stabilize this putative pathobiology relationship between them.
