Investment strategies and coordination for green food supply chain: a further research considering the inputs of the blockchain-based traceability system
Authors: Liu Pan 
Published: January 2023

PurposeTo study these issues, the authors chose a GFSC with one producer and one material supplier as research object, the supplier will offer green material to the producer and the producer will make green food using green production technology. Then, the authors proposed that consumers' perceived value was determined by the trustworthiness levels of the related green and quality-safety information provided by the supplier and the producer. Then, considering the trustworthiness levels of the green and quality information provided by the supplier and the producer, the authors improved the demand function. Afterwards, we constructed four investment models and their income models are built and then a cost-sharing and revenue-sharing contract (hereafter, CSRS) was adopted to coordinate the GFSC.Design/methodology/approachWith the growth of consumers environmental awareness and life level, consumers' requirements for green and high quality food are growing. In recently years, to increase consumers' perceived trustworthiness on the product greenness and quality levels, stakeholders in green food supply chain (hereafter, GFSC) start to adopt the blockchain-based traceability system (hereafter, BLTS). For investors, they need to know the investment conditions and how to coordinate the GFSC.Findings(1) When the revenue-sharing coefficient is less than three-fourths and higher then a certain vaule, the cost-sharing and revenue-sharing contract can make the GFSC coordinate. (2) The investment cost threshold of the BLTS has a positive relationship with the trustworthiness improvement levels of the green and quality information, the green degree of food products and the quality of food products. (3) In the proposed four investment situations, as the growth of consumers perceived credibility coefficient about the greenness information and the quality information, chain members' revenues will increase. In addition, comparing with co-investing the BLTS, benefits of chain members are lower than them in the sole investment model.Originality/value(1) The demand function we proposed can help chain members forecast market demand to support production or ordering decisions. (2) The investment decision policies can offer a theoretical reference for chain members to use the BLTS. (3) The CSRS will offer the theoretical reference for coordinating the supply chain after using the BLTS. Furthermore, our study method can be referenced by other scholars. (4) The study method can offer a method reference for researchers who do a similar discussion in a manufacturing supply chain. Although, our research cannot guide the industrial practices, it can serve as a reference of the similar research in industry.

Abstract

Most statistical models of microclimate focus on the difference or ‘offset’ between standardized air temperatures (macroclimate) and those of a specific habitat such as forest understorey, grassland or under a log. However, these offsets can fluctuate from positive to negative over a single day such that common practice consists in aggregating data into daily mean, minimum and maximum before modelling monthly offsets for each summary statistic. Here, we propose a more parsimonious and flexible approach relying on just two parameters: the slope and equilibrium. The slope captures the linear relationship between microclimate and macroclimate, while the equilibrium is the point at which microclimate equals macroclimate. Although applicable to other habitats, we demonstrate the relevance of our method by focusing on forest understoreys.

We installed temperature sensors at 1‐m height inside forest stands and in nearby open grasslands equipped with standardized weather stations, across 13 sites in France spanning a wide climatic gradient. From a year of hourly temperatures and for each sensor, we established relationships between microclimate and macroclimate temperatures using two linear mixed‐effects models, during the leaf‐on (May–November) and leaf‐off period (December–April). We extracted the monthly equilibrium and slope for each sensor, and used another set of linear mixed‐effects models to investigate their main determinants.

The slope was chiefly determined by stand structure variables interacting with the leaf‐on/leaf‐off period: stand type (conifer vs broadleaf); shade‐casting ability; stand age; dominant height; stem density; and cover of the upper and lower shrub layer. In contrast, forest structure had no explanatory power on the equilibrium. We found the equilibrium to be positively related to mean macroclimate temperature, interacting with the open/forest habitat.

The method introduced here overcomes several shortcomings of modelling microclimate offsets. By demonstrating that the slope and equilibrium vary in predictable ways, we have established a general linkage between microclimate and macroclimate temperatures that can be applied to any location or time if we know the mean macroclimate temperature (equilibrium) and buffering or amplifying capacity of the habitat (slope). We also warn about methodological biases due to the reference used for macroclimate.

AbstractThis longitudinal study modeled children's complex executive function (EF) development using the Groton Maze Learning Task (GMLT). Using a cohort‐sequential design, 147 children (61 males, 5.5–11 years) were recruited from six multicultural primary schools in Melbourne and Perth, Australia. Race/ethnicity data were not available. Children were assessed on the GMLT at 6‐month intervals over 2‐years between 2010 and 2012. Growth curve models describe age‐related change from 5.5 to 12.5 years old. Results showed a quadratic growth trajectory on each measure of error—that is, those that reflect visuospatial memory, executive control (or the ability to apply rules for action), and complex EF. The ability to apply rules for action, while a rate‐limiting factor in complex EF, develops rapidly over early‐to‐mid childhood.

AbstractIt is still controversial whether surgical or nonsurgical treatment approaches are most appropriate for empyema in children, and there are no data regarding the role of medical thoracoscopy in this population. The aim of this study was to describe our experience with medical thoracosocpy in children with multiloculated and organizing pneumonia. We retrospectively reviewed children admitted to our hospital with a diagnosis of empyema from 2011 to 2021 and treated with medical thoracoscopy. A total of six patients with empyema were treated by medical thoracoscopy; empyema was multiloculated in five cases and organized in one case; all children in the study recovered completely with full lung expansion after chest X‐rays, and no disease sequelae were reported after clinical follow‐up. Our small case series suggests that in selected cases, medical thoracoscopy could safely and effectively treat pleural empyema in children, with less invasiveness and reduced psychological consequences.

AbstractAimsTo investigate changes in cardiac repolarisation during exercise‐related hypoglycaemia compared to hypoglycaemia induced at rest in people with type 1 diabetes.Material and methodsIn a randomised crossover study, 15 men with type 1 diabetes underwent two separate hyperinsulinaemic euglycaemic‐hypoglycaemic clamp experiments during Holter‐ECG monitoring. One experiment included a bout of moderate‐intensity cycling exercise (60 min) along with declining plasma glucose (PG; Clamp‐exercise). In the other experiment, hypoglycaemia was induced with the participants at rest (Clamp‐rest). We studied QTc interval, T‐peak to T‐end (Tpe) interval and hormonal responses during three steady‐state phases: (i) baseline (PG 4.0–8.0 mmol/L); (ii) hypoglycaemic phase (PG <3.0 mmol/L); and (iii) recovery phase (PG 4.0–8.0 mmol/L).ResultsBoth QTc interval and Tpe interval increased significantly from baseline during the hypoglycaemic phase but with no significant difference between test days. These changes were accompanied by an increase in plasma adrenaline and a decrease in plasma potassium on both days. During the recovery phase, ΔQTc interval was longer during Clamp‐rest compared to Clamp‐exercise, whereas ΔTpe interval remained similar on the two test days.ConclusionsWe found that both exercise‐related hypoglycaemia and hypoglycaemia induced at rest can cause QTc‐interval prolongation and Tpe‐interval prolongation in people with type 1 diabetes. Thus, both scenarios may increase susceptibility to ventricular arrhythmias.
Teeth outside the mouth: The evolution and development of shark denticles

Published: January 2023

AbstractVertebrate skin appendages are incredibly diverse. This diversity, which includes structures such as scales, feathers, and hair, likely evolved from a shared anatomical placode, suggesting broad conservation of the early development of these organs. Some of the earliest known skin appendages are dentine and enamel‐rich tooth‐like structures, collectively known as odontodes. These appendages evolved over 450 million years ago. Elasmobranchs (sharks, skates, and rays) have retained these ancient skin appendages in the form of both dermal denticles (scales) and oral teeth. Despite our knowledge of denticle function in adult sharks, our understanding of their development and morphogenesis is less advanced. Even though denticles in sharks appear structurally similar to oral teeth, there has been limited data directly comparing the molecular development of these distinct elements. Here, we chart the development of denticles in the embryonic small‐spotted catshark (Scyliorhinus canicula) and characterize the expression of conserved genes known to mediate dental development. We find that shark denticle development shares a vast gene expression signature with developing teeth. However, denticles have restricted regenerative potential, as they lack asox2+ stem cell niche associated with the maintenance of a dental lamina, an essential requirement for continuous tooth replacement. We compare developing denticles to other skin appendages, including both sensory skin appendages and avian feathers. This reveals that denticles are not only tooth‐like in structure, but that they also share an ancient developmental gene set that is likely common to all epidermal appendages.
Sexual conflict and the evolution of monandry: The case of the damselfly Ischnura hastata (Odonata: Coenagrionidae) in the Galápagos Islands

Abstract
Sexual selection favours the evolution and maintenance of polygamy, which is the dominant reproductive strategy in insects. Monogamy can evolve in very short‐lived species due to time constraints. Here we study adult activity and mating behaviour of a population of the damselfly Ischnura hastata, a species rarely seen mating, and which has been suggested to be monandric, in wetlands of Isabela Island, Galápagos.
By means of mark‐recapture methods, we estimated that the daily survival rate was low, ranging from 0.385 to 0.876, yielding average life expectancies of mature individuals of only 1.2–3.2 days. Adults showed very low activity before 7:00, indicating that mating does not occur early. The number of male–female interactions and mating attempts was extremely low, with only 44 copulations recorded on over 230 h of observations.
Copulations were brief, with a mean duration of 11 min (but only two were observed from the start). Males showed clear preference to attempt to grasp in tandem females of intermediate age (in 94.3% of cases), rather than young (31.3%) or mature females (24.0%). Males were very persistent once a tandem was achieved, retaining females for up to 139 min, but most females resisted and did not copulate.
We conclude that females of I. hastata show a very short time window to mate, exactly when they change colour from juvenile to mature, and live only enough to mate once. Short lifespan has selected for female monandry in I. hastata, creating an intense sexual conflict over mating rates.
The process of organizational identification in social enterprises: The role of coalitions
Authors: Godfroid Cécile , Labie Marc 
Published: January 2023

AbstractThis paper offers a detailed and systemic representation of the process of organizational identification in social enterprises, and a better understanding of how individuals position themselves in these organizations. We highlight that identification in social enterprises is the result of the interplay between the multiple identities of the individuals who take part in coalitions defending different institutional logics. Identification will depend on whether or not it is easy for the individual to find a coalition that corresponds to him or her, and on whether or not the ideas of this coalition are dominant. The relative size of the various coalitions among the staff and the way they evolve will have a clear impact on what the dominant logic of the social enterprise will be.

Published: January 2023

AbstractDiabetic nephropathy is the leading cause of end‐stage renal failure, but the effectiveness of currently available strategies for preventing diabetic nephropathy remains unsatisfactory. This study was designed to evaluate the changes in adipokines levels caused by dipeptidyl peptidase‐4 inhibitor sitagliptin therapy as one of the possible mechanisms of sitagliptin's amelioration of diabetic nephropathy. Twenty‐four male Wistar rats weighing 180–200 g were taken and divided into three groups, that is, control, diseased, and treatment group. High‐fat diet and streptozotocin‐induced Type 2 diabetic rats were divided into diseased and treatment groups. The treatment group was given sitagliptin orally, 10 mg/kg per day for 6 weeks. Serum glucose, serum insulin, serum blood urea nitrogen, serum creatinine, and 24‐h urinary protein levels were measured in serum and urine samples. mRNA expression levels of podocin, nephrin, and adipokines in renal tissues were determined. Results showed that sitagliptin treatment effectively reduced serum glucose, serum creatinine, serum blood urea nitrogen, and 24‐h proteinuria, along with partial prevention of insulinopenia, in the treatment group as compared to the diseased group. The renal mRNA expression levels of podocin, nephrin, and adiponectin were significantly upregulated, while those of leptin and resistin were significantly downregulated in the diabetic rats receiving sitagliptin therapy compared to the non‐treated diabetic rats. Based on these findings, it is suggested that sitagliptin, via mediating the modulation of adipokines levels, upregulates renal nephrin and podocin expression, which leads to the amelioration of diabetic nephropathy.

Published: January 2023

SummaryThis study aims to evaluate the fat‐substituting feature of the complex of whey protein isolate (WPI) and dextran structure exopolysaccharide (EPS) synthesised by Weissella confusa JCM 1093 strains in mayonnaise samples. The flow behaviour, frequency sweep and three interval thixotropy test properties of the samples were compared with the control groups. Thermal loop test was applied to determine the emulsion stability of the samples. Oxidative stability was tested with OXITEST, and induction period values were compared. K values of the samples varied between 20.05 and 169.13 Pa.sn and the n values vary between 0.133 and 0.383. Samples showed pseudoplastic behaviour (n < 1). G' of all samples is greater than G", meaning that all samples showed a solid‐like behaviour like conventional mayonnaise. The complex of 2% EPS and 5% WPI provided a solid structure and improved the physical stability of low‐fat mayonnaise. The results showed that the samples had high physical stability when they experienced thermal stress at low and high temperatures. As a result, the WPI and EPS complex can be used as a fat replacer for improving the rheological properties, emulsion and oxidative stability in low‐fat mayonnaise samples.
New insight into SiOC atomic structure evolution during early stage of pyrolysis
Authors: Lu Kathy , Chaney Harrison 
Published: January 2023

AbstractThis study focuses on the early stage of polymer‐derived SiOC ceramic conversion. We demonstrate that the perceived SiOC phase separation is nonexistent. Instead, SiO2 and free carbon clusters form first and then carbothermal reduction sets in to induce SiOC formation. Such fundamental understanding is supported by both synchrotron X‐ray diffraction study and reactive force field simulation. This work for the first time unifies the understanding of atomic evolution process of polysiloxane‐based polymer to ceramic conversion.

Published: January 2023

AbstractAimTo evaluate the association between leisure‐time/occupational physical activity (LTPA/OPA) and periodontitis in a nationally representative sample of the U.S. population.Materials and MethodsData from 10,679 adults were retrieved from NHANES 2009–2014 database. Physical activity was assessed through the Global Physical Activity Questionnaire, and accordingly, subjects were classified as performing either high or low LTPA/OPA. Periodontal status was assessed through a full‐mouth periodontal examination, and subjects were classified according to the AAP/CDC criteria (no, mild, moderate, or severe periodontitis). Simple and multiple regression analyses were applied to study the association between LTPA/OPA and periodontitis/severe periodontitis.ResultsMultiple regression analyses identified high LTPA as a protective indicator for periodontitis (odds ratio [OR] = 0.81; 95% confidence interval [CI]: 0.72–0.92), while high OPA was found to be a significant risk indicator (OR = 1.16; 95% CI: 1.04–1.30). The combination low LTPA/high OPA showed a cumulative independent association with periodontitis (OR = 1.47; 95% CI: 1.26–1.72). Moreover, both high LTPA (OR = 0.72; 95% CI: 0.58–0.90) and high OPA (OR = 1.29; 95% CI: 1.09–1.53) were significantly associated with stronger estimates of severe periodontitis; the same was observed for the combination of low LTPA/high OPA (OR = 1.66; 95% CI: 1.29–2.15).ConclusionsLTPA and OPA showed divergent associations with periodontitis.

AbstractObjectiveTo understand the relationship between perceived discrimination, allostatic load, and all‐cause mortality; and to determine whether allostatic load is a mediator in the relationship between perceived discrimination and all‐cause mortality among an older adult US population.MethodsData from the Health and Retirement Study (2006–2012) was analyzed. Cox proportional hazard models were used to investigate the relationship between all‐cause mortality and perceived discrimination, and all‐cause mortality and allostatic load. Linear regression models were used to investigate the relationship between perceived discrimination and allostatic load. A mediation model with perceived discrimination and allostatic loads as independent variables was used to determine the association with all‐cause mortality.ResultsThere were 5062 adults over the age of 50 included in the analysis. The relationship between perceived discrimination and allostatic load was statistically significant (b:0.14, [95%CI 0.10,0.19]; p < 0.001). The relationship between perceived discrimination and all‐cause mortality was statistically significant (HR: 1.12, [95%CI 1.03,1.22]; p = 0.01). The relationship between allostatic load and all‐cause mortality was statistically significant (HR: 1.11, [95%CI 1.08,1.13]; p < 0.001). The mediation model resulted in a decrease in hazard ratio and loss of statistical significance for perceived discrimination (HR: 1.09, [95%CI 0.98,1.21]; p = 0.13) when allostatic load (HR: 1.17, [95%CI 1.10,1.24]; p < 0.001) was added to the Cox regression model, indicating full mediation.ConclusionsAllostatic load fully mediates the relationship between perceived discrimination and all‐cause mortality. Understanding the role of allostatic load in this relationship provides an additional implication for screening and indications for tighter control of the modifiable components of allostatic load by healthcare providers, especially among individuals who experience discrimination.
