More autonomy, more proactive? The (in)congruence effects of autonomy on proactive behaviour
Authors: Yang Chang , Bao Yuanjie , Zhang Zixu 
Published: January 2024

PurposeBased on person-job fit and self-determination theory, this paper examined the effects of (in)congruence between autonomy expectation and perceived autonomy on proactive behaviour, and the moderating role of humble leadership in this relationship among Chinese public employees.Design/methodology/approachData were collected from a two-wave survey, and the research model was tested using polynomial regression and response surface methodology.FindingsResults suggested that employees' proactive behaviour will be highest when autonomy congruence was achieved, while autonomy incongruence led to different levels of proactive behaviour based on the specific situations. Furthermore, the moderating effect of humble leadership was proved such that it accentuated the positive influence of autonomy congruence on proactive behaviour.Practical implicationsManagers should be fully aware of the benefits and importance of person-job fit and strive to reduce autonomy incongruence. Meanwhile, humble leadership should be considered in the context of granting autonomy to boost proactivity.Originality/valueThis paper re-emphasises the importance of autonomy by utilising a congruence perspective to understand the effects of autonomy on proactive behaviour. Meanwhile, it incorporates an important boundary condition, humble leadership, on the effects of autonomy congruence and thus offers a more nuanced understanding. Further, this paper not only highlights the significance of underexplored concepts among public employees, but also extends autonomy (in)congruence study to a new context and culture.
Fish gill surface area can keep pace with metabolic oxygen requirements across body mass and temperature
Authors: Skeeles M. R. , Clark T. D. 
Published: January 2024

Abstract

Climate warming is driving the maximum attainable size of many fish species to decrease, yet the mechanisms underlying this ‘shrinking’ phenomenon are not well understood. The gill oxygen limitation (GOL) hypothesis is perhaps the most prominent mechanistic proposition, asserting that, as fish grow, the two‐dimensional gill surface area (GSA) progressively fails to supply enough oxygen to support the continued growth of the three‐dimensional body—a process exacerbated by increased metabolism associated with warming. However, these ideas have been hotly debated owing to limited empirical understanding of how GSA develops with respect to a fish's body mass and oxygen requirements.

For the first time, we addressed this knowledge gap by rearing Galaxias maculatus for 5 months at normal (15°C) and elevated (20°C) summer temperatures, with (hyperoxia) or without (normoxia) supplementary oxygen. Quantifying individual metabolic rate and GSA traits across body sizes encompassing most of the species' ontogeny, we found little evidence for a change in the proportion of GSA available per unit of metabolic rate (termed the S metric) and no improvements under hyperoxia.

Importantly, at the elevated temperature where gill oxygen limitation should be most pronounced, the S metric did not change across body mass in either oxygen treatment (allometric exponents were no different from 0).

These results indicate that the gills can grow in ways that support an individual's oxygen requirements, contrasting with the suggestion that size reductions of fish in response to climate warming are driven by an insurmountable geometric constraint at the gills.

Abstract

Ecological processes such as environmental filtering and biotic interactions that shape species' traits and community diversity often vary with geographic distance, potentially generating spatial structures in trait variation, covariation and biodiversity data. Understanding spatial structures of trait, environment and biodiversity, or the spatial link between those factors, is fundamental to identifying spatially explicit assembly processes or biodiversity distributions in spatially heterogeneous landscapes but remains unclear.

To address the issue, we gathered individual‐level leaf and diameter traits data paired with environmental data from a 4.8 ha subtropical Chinese forest and divided the forest into 25, 100, 400 and 1936 m2 grids representing contrasting spatial grains. Using Moran's correlograms, we quantified the spatial structures of trait variation and covariation, environmental conditions and biodiversity. We assessed the links between those variables using path analyses.

Most variables were spatially positively autocorrelated. However, trait mean was more autocorrelated than trait variation or covariation, and intraspecific trait variation was more autocorrelated than interspecific variation. Autocorrelations in those community properties were generally weak at the large grain.

Path analyses indicated positive associations between interspecific trait variation and species diversity at a very small to medium scale and a positive association between intraspecific variation and small‐scale functional diversity. Trait covariation constrained biodiversity, and multi‐trait means were negatively linked to very small‐ to medium‐scale species diversity but positively to medium‐ and large‐scale functional diversity. Patterns regarding multi‐trait community structure–environment–biodiversity associations were generally held for individual traits. However, depending on the trait, spatial scale and plant ontogenic stage, the pattern's strength changed, or occasionally, their sign reversed.

We attribute spatial patterns in multi‐trait mean and covariation to scale‐dependent variation in environmental heterogeneity and trait variation to scale‐dependent competition.

Synthesis. Our study provides novel insights into spatial and scale‐dependent variability in functional community structure, environment and biodiversity, and their relationships. Our results demonstrate the usefulness of spatial trait analyses in identifying scale‐dependent assembly processes or finding the importance of processes to biodiversity distributions in spatially heterogeneous landscapes. A spatially explicit perspective is thus helpful for the progress of trait ecology.
Silent responsiveness: How public opinion affects party discourse on wedge issues
Authors: MALET GIORGIO , THIÉBAUT CYRILLE 
Published: January 2024

AbstractHow does public opinion affect political discourse on issues that parties struggle to deal with? Although scholars tend to analyse party–voter linkages in terms of policy positions, parties can respond to public opinion by changing both the positions and the salience of their policy agenda. Based on original time‐series data of party discourse and voter preferences in France, Italy and the United Kingdom (1992–2016), this paper analyses how mainstream parties have changed their political discourse on European integration in response to an increasingly Eurosceptic public. Results show that mainstream parties have adapted their positions to changes in public opinion and have at the same time deemphasized European Union issues in their discourse as the public grew Eurosceptic. Parties did not talk more about Europe even when they followed the tides of public opinion. These findings challenge our current understanding of party responsiveness, have implications for theories of party competition, and contribute to debates on the legitimacy of the European project.
Disillusionment and hope with transnational mothers: Avenues of change in education through acompañamiento
Authors: Contreras Ana 
Published: January 2024

AbstractThis critical ethnographic study explores a participatory action research group consisting of Latin American immigrant mothers seeking to involve their community in school decision‐making. Drawing from pedagogies of acompañamiento, I describe how the mothers responded to decision‐making challenges and leveraged reflections on their struggles to co‐create knowledge and belonging. I demonstrate how their collective learning highlights transformation outside of formal policy channels, pushing us to consider alternative ways of making social change.
Induced pluripotent stem cell models as a tool to investigate and test fluid biomarkers in Alzheimer's disease and frontotemporal dementia
Authors: McInvale Julie J. , Canoll Peter , Hargus Gunnar 
Published: January 2024

AbstractNeurodegenerative diseases are increasing in prevalence and comprise a large socioeconomic burden on patients and their caretakers. The need for effective therapies and avenues for disease prevention and monitoring is of paramount importance. Fluid biomarkers for neurodegenerative diseases have gained a variety of uses, including informing participant selection for clinical trials, lending confidence to clinical diagnosis and disease staging, determining prognosis, and monitoring therapeutic response. Their role is expected to grow as disease‐modifying therapies start to be available to a broader range of patients and as prevention strategies become established. Many of the underlying molecular mechanisms of currently used biomarkers are incompletely understood. Animal models and in vitro systems using cell lines have been extensively employed but face important translatability limitations. Induced pluripotent stem cell (iPSC) technology, where a theoretically unlimited range of cell types can be reprogrammed from peripheral cells sampled from patients or healthy individuals, has gained prominence over the last decade. It is a promising avenue to study physiological and pathological biomarker function and response to experimental therapeutics. Such systems are amenable to high‐throughput drug screening or multiomics readouts such as transcriptomics, lipidomics, and proteomics for biomarker discovery, investigation, and validation. The present review describes the current state of biomarkers in the clinical context of neurodegenerative diseases, with a focus on Alzheimer's disease and frontotemporal dementia. We include a discussion of how iPSC models have been used to investigate and test biomarkers such as amyloid‐β, phosphorylated tau, neurofilament light chain or complement proteins, and even nominate novel biomarkers. We discuss the limitations of current iPSC methods, mentioning alternatives such as coculture systems and three‐dimensional organoids which address some of these concerns. Finally, we propose exciting prospects for stem cell transplantation paradigms using animal models as a preclinical tool to study biomarkers in the in vivo context.
Perception of beach safety at a destination beach on the Great Lakes
Authors: Houser Chris , Smith Alex 
Published: January 2024

AbstractSurf‐related drowning fatalities are a public health concern in the Great Lakes region of North America, and within Canada there are few beaches with lifeguards and no regional beach safety strategy. This short paper presents the results of a survey completed in the northern hemisphere summer of 2022 to determine the perceptions of beach users at Station Beach in Kincardine, Ontario, a popular tourist beach town on Lake Huron. Results suggest that beach safety knowledge and choice of location to occupy along the beach depend on experience with the beach, with frequent visitors tending to select quieter locations located further from a jetty that can result in a structural rip current. Infrequent visitors tended to be closer to the jetty and selected that location based on convenience (e.g., close to parking), suggesting the need for structural changes to guide behaviour towards safer areas of the beach. Results also highlight the challenges of developing an effective warning system to inform beach users of potentially dangerous surf and currents in the absence of an investment in lifeguards or a regional/provincial beach safety strategy.

AbstractPathogenic heterozygous loss of function variants in CTNNB1 are associated with CTNNB1 neurodevelopmental disorder. We report the clinical phenotype of individuals with CTNNB1 neurodevelopmental disorder using both caregiver‐reported data (medical history, adaptive function, quality of life, and behavior issues) and in‐person clinical assessments (neurological, motor, and cognitive function) in 32 individuals with likely pathogenic or pathogenic CTNNB1 variants. Most individuals had truncal hypotonia, muscle weakness, hypertonia, dystonia, microcephaly, and many had a history of tethered cord. Visual problems included strabismus, hyperopia, and familial exudative vitreoretinopathy. Half of individuals walked without an assistive device. The mean Gross Motor Functional Measure‐66 score was 56.6 (SD = 14.8). Average time to complete Nine‐Hole Peg Test was slower than norms. Mean general conceptual ability composite scores from Differential Ability Scales Second Edition were very low (M = 58.3, SD = 11.3). Fifty‐five percent of individuals had low adaptive functioning based on the Vineland Adaptive Behavioral Scales. Based upon the Child Behavior Checklist total problems score, the majority (65%) of individuals had behavioral challenges. The mean overall Quality of Life Inventory‐Disability score was 81.7 (SD = 11.9). These data provide a detailed characterization of clinical features in individuals with CTNNB1 neurodevelopmental disorder.
The impact of COVID‐19 on price transmission and price volatility in the Canadian beef supply chain
Authors: Zheng Yanan , An Henry , Yang Meng , Qiu Feng 
Published: January 2024

AbstractThe COVID‐19 pandemic resulted in disruptions to the Canadian meat and livestock markets. While prices initially decreased, the shutdowns of beef packing plants led to a large reduction in the supply of beef and a corresponding increase in the wholesale price with ramifications along the entire supply chain. This study examines the effect of COVID‐19 on price transmission and price volatility in the Canadian beef supply chain using monthly farmgate, wholesale, and retail price data covering the period from July 2005 to February 2022. We find evidence indicating that COVID‐19 affected long‐run price transmission from farmgate and wholesale markets to the retail market. Specifically, we find that the pandemic resulted in a 94.42 and 81.48% decrease in price transmission from the farmgate and wholesale market, respectively, to the retail market, indicating that higher prices at the wholesale level were not being passed on to consumers to the same extent. In the short run, we find asymmetric price adjustments and both direct and indirect volatility spillovers among the three levels of markets, implying strong market interactions across the beef supply chain. Overall, our results suggest the resiliency of the Canadian beef sector to COVID‐19 shocks.

AbstractAimThe aim was to estimate the 10‐year cost−utility of haemorrhoidectomy surgery with preference‐based measures of health using Canadian health utility measures and costs.MethodsPatients undergoing elective haemorrhoidectomies by general and colorectal surgeons in British Columbia, Vancouver, between September 2015 and November 2022, completed preoperatively and postoperatively the EuroQol five‐dimension five‐level health‐related quality of life questionnaire (EQ‐5D‐5L). Quality‐adjusted life years (QALYs) attributable to surgery were calculated by discounting preoperative and postoperative health utility values derived from the EQ‐5D‐5L. Costs were measured from a health system perspective which incorporated costs of hospital stay and specialists' fees. Results are presented in 2021 Canadian dollars.ResultsOf 94 (47%) patients who completed both the preoperative and postoperative questionnaires, the mean gain in QALYs 10 years after surgery was 1.0609, assuming a 3.5% annual discounting rate. The average cost of the surgery was $3166. The average cost per QALY was $2985 when benefits of the surgery were assumed to accrue for 10 years. The cost per QALY was higher for women ($3821) compared with men ($2485). Participants over the age of 70 had the highest cost per QALY ($8079/QALY).ConclusionsHaemorrhoidectomies have been associated with significant gains in health status and are inexpensive relative to the associated gains in quality of life based on patients' perspectives of their improvement in health and well‐being.

Published: January 2024

AbstractAimChronotype reflects a circadian rhythmicity that regulates endothelial function. While the morning chronotype (MORN) usually has low cardiovascular disease risk, no study has examined insulin action on endothelial function between chronotypes. We hypothesized intermediate chronotypes (INT) would have lower vascular insulin sensitivity than morning chronotype (MORN).Materials and MethodsAdults with obesity were classified per Morningness‐Eveningness Questionnaire (MEQ) as either MORN (n = 27, 22 female, MEQ = 63.7 ± 4.7, 53.8 ± 6.7 years, 35.3 ± 4.9 kg/m2) or INT (n = 29, 23 female, MEQ = 48.8 ± 6.7, 56.6 ± 9.0 years, 35.7 ± 6.1 kg/m2). A 120 min euglycaemic‐hyperinsulinaemic clamp (40 mU/m2/min, 90 mg/dl) was conducted to assess macrovascular insulin sensitivity via brachial artery flow‐mediated dilation (%FMD; conduit artery), post‐ischaemic flow velocity (resistance arteriole), as well as microvascular insulin sensitivity via contrast‐enhanced ultrasound [e.g. microvascular blood volume (perfusion)]. Fasting plasma arginine and citrulline, as well as fasting and clamp‐derived plasma endothelin‐1 and nitrate/nitrite, were assessed as surrogates of vasoconstriction and nitric oxide‐mediated vasodilation. Aerobic fitness (VO2max) and body composition (dual‐energy X‐ray absorptiometry) were also collected.ResultsMORN had a higher VO2max compared with INT (p < .01), although there was no difference in fat mass. While fasting FMD was similar between groups, insulin lowered FMD corrected to shear stress and microvascular blood volume in INT compared with MORN after co‐varying for VO2max (both p ≤ .02). INT also had a lower fasting nitrate (p = .03) and arginine (p = .07). Higher MEQ correlated with elevated FMD (r = 0.33, p = .03) and lower post‐ischaemic flow velocity (r = −0.33, p = .03) as well as shear rate (r = −0.36, p = .02) at 120 min.ConclusionWhen measured during the morning, INT had a lower vascular insulin sensitivity than MORN. Additional work is needed to understand endothelial function differences among chronotypes to optimize cardiovascular disease risk reduction.
Evolution of realized niche breadth diversity driven by community dynamics
Authors: Kyogoku Daisuke 
Published: January 2024

AbstractWhy many herbivorous insects are host plant specialists, with non‐negligible exceptions, is a conundrum of evolutionary biology, especially because the host plants are not necessarily optimal larval diets. Here, I present a novel model of host plant preference evolution of two insect species. Because habitat preference evolution is contingent upon demographic dynamics, I integrate the evolutionary framework with the modern coexistence theory. The results show that the two insect species can evolve into a habitat specialist and generalist, when they experience both negative and positive frequency‐dependent community dynamics. This happens because the joint action of positive and negative frequency dependence creates multiple (up to nine) eco‐evolutionary equilibria. Furthermore, initial condition dependence due to positive frequency dependence allows specialization to poor habitats. Thus, evolved habitat preferences do not necessarily correlate with the performances. The model provides explanations for counterintuitive empirical patterns and mechanistic interpretations for phenomenological models of niche breadth evolution.

Published: January 2024

AbstractA molecular tool has been set up for the unambiguous molecular identification of the ambrosia beetle, Xyleborinus saxesenii (Ratzeburg, 1837) (Coleoptera Curculionidae Scolytinae), the cosmopolitan fruit‐tree pinhole borer, widely distributed in temperate regions of the five continents, where it infests a wide range of hardwoods and softwoods. The test was based on real‐time PCR with TaqMan probe technology and was developed on whole insect bodies (adults) as well as on frass produced by the beetle. The test was shown to meet the criteria established by EPPO for the harmonization of molecular diagnostic methods. In particular, the test gave good results in terms of analytical specificity (inclusivity and exclusivity) and analytical sensitivity, and was fully repeatable and reproducible. Since X. saxesenii is one of the most commonly intercepted ambrosia beetles during phytosanitary controls worldwide, this practical diagnostic tool will be useful for its rapid identification of the beetle in biological material (frass, body fragments). The test can be useful in countries where X. saxesenii is a quarantine species, as well as in the EPPO region.
Beyond accuracy: The development of syntactic complexity in middle school Spanish immersion
Authors: Menke Mandy R. 
Published: January 2024

AbstractLanguage immersion programs seek to develop multilingual, multiliterate individuals able to engage with academic content. Studies of immersion students' language development provide details regarding language proficiency and accuracy, yet they generally do not address how features of written, academic language, for example, syntactic and lexical complexity, develop. To this end, this study seeks to understand if and how the syntactic complexity of written texts produced by middle school Spanish immersion students differs across grades. It examines discipline‐related, persuasive texts written by 186 Grade 6–8 Spanish immersion students from five programs, analyzing syntactic complexity at the phrasal, clausal, and supraclausal levels and considering both length‐based and subordination measures. Findings suggest that syntactic complexity does not change significantly in middle school for immersion students unlike findings with nonimmersion students. Explanations for and implications of the findings are explored.
