Going green in Thailand: Upgrading in global organic value chains
Authors: Moore Joel D. , Donaldson John A. 
Published: April 2023

AbstractUnder what conditions are some small‐scale agricultural producers able to overcome challenges associated with shifting to organic production, whereas most are not? The answers are vital for the global effort to encourage more sustainable, pro‐poor forms of agriculture—more organic farming, more sustainable production; more smallholders engaged in green production, more income and better livelihoods. Yet, answering this question is challenging in part because previous analyses of global production networks, such as those associated with organic agriculture, focus more on broad governance patterns than the specific factors and actors that help smallholders shift to organic production and link to far‐flung markets. To fill in these gaps, we conducted fieldwork in Isan, Thailand, a major rice‐producing area in which many groups of smallholders have attempted to shift into organic production. Doing so allows us to identify the critical challenges associated with upgrading into organic production and analyse how specific actors enabled some groups to overcome these challenges. Our findings provide a generalizable theoretical approach to understanding how to link small‐scale farmers to global value chains in ways that can potentially enhance smallholders' livelihoods, spark rural development and encourage more sustainable practices in agriculture.
Passion Amid the Pandemic: Applying a Person‐Centered Approach to Examine Cross‐Domain Multi‐Passion Profiles during a Crisis
Authors: Astakhova Marina N. , Ho Violet T. , McKay Alexander S. 
Published: April 2023

AbstractWe examine whether having cross‐domain passion (i.e., harmonious and obsessive passion for work and for non‐work activities) during the COVID‐19 pandemic can help individuals fare better amid the crisis. Drawing from work‐family boundary framework, we develop a provisional theory of cross‐domain multi‐passion, and in two studies, we use latent profile analysis to uncover five passion profiles – Dispassionate at Work and Play; Dispassionate at Work, Ambidextrous at Play; Harmonious at Work, Ambidextrous at Play; Harmonious at Work and Play; and Moderately Harmonious at Work and Play. In Study 1, we inductively explore these profiles and their relationships with life satisfaction. In Study 2, we replicate the number and content of these profiles, and test whether segmentation‐integration preferences and work and non‐work constraints predict the probability of individuals belonging to a certain profile. Overall, these profiles reveal how individuals can co‐host multiple forms of passion simultaneously, and how doing so relate to their life satisfaction during the pandemic.

Published: April 2023

AbstractIn May 2019, a two‐year‐old pomegranate orchard cultivar “Wonderful”, located in Central Italy, showed extensive black pitting and longitudinal cankers on twigs as well as apical leaf wilting. Bacterial isolates were identified by applying biochemical, molecular and pathogenicity assays. All isolates showed identical biochemical characteristics typical of Pseudomonas syringae. In addition, upon artificial inoculations, the isolates caused symptoms in pomegranate twigs and leaves similar to those observed in the field, and in lemon fruit and pear leaves. The isolates possess the syrB gene. An ERIC‐PCR fingerprinting analysis revealed an identical pattern for the strains isolated from pomegranate and other strains previously obtained from lemon and chickpea, in Tunisia and Italy, respectively, as well as a similarity with other strains obtained from different host plants. The 16S rRNA gene analysis showed a very high similarity with other P. s. pv. syringae strains. The study allowed to conclude that the disease was caused by P. s. pv. syringae, reported for the first time as a pathogen for pomegranate. Frost and high humidity could have favoured the outbreak. The year after the outbreak, a formulate that contains zinc, copper, manganese, chitosan and garlic powder, effectively reduced the severity of the disease in the field.

Participants were recruited from the day hospital and/or outpatient services of four hospitals in Northern Portugal, the majority being mothers (87.3%) aged between 31 and 50 years (86.9%). The questionnaire was administered online through the REDCap platform. The hierarchical factor model of the Pediatric Quality of Life Inventory™ Family Impact Module proposed by Varni and colleagues was tested.ResultsConfirmatory Factor Analysis indicated good model fit, with the following indices (χ2/gL = 2.19; comparative fit index [CFI] = 0.90; root mean square error of approximation [RMSEA] = 0.07 immune cell [IC] 90% = 0.06−0.07). Internal consistency values were high (parent quality of life subtotal, α = .96; family functioning subtotal, α = .92; total score, α = .96).Practice ImplicationsThe European Portuguese version of the PedsQL™ FIM is a reliable and valid measurement tool for nurses to assess the impact of the child/adolescent chronic conditions on family's quality of life and to develop interventions to improve their well‐being.
Demographic monitoring of the invasive ladder snake on Formentera (Balearic Islands, Spain)

Published: April 2023

AbstractThe ladder snake Zamenis scalaris was first reported in 2006 in Formentera (Balearic Islands, Spain), until then a snake‐free Mediterranean island. Since 2016, intense control campaigns have been carried out and, for the first time, snake captures over 2017–2020 have been used to analyze the sex ratio, age, fat percentage, population density, and seasonality of this invasive population. The male‐biased sex ratio found in the present work could be the result of capture biases caused by different detection probabilities between sexes. A reduction of snake body length over time was observed, which could indicate a depletion of the larger snakes due to intense snake capture. The highest capture frequencies of both sexes were reported in May and June, coinciding with the mate searching period in the species native range and indicating that snakes increase their movements during this period. Size‐specific survivorship curves indicated a drop in survivorship at medium sizes, which suggested a survival cost associated with reproduction, presumably due to increased mortality during the mating season. Population density decreased from 1.812 snakes/ha in 2017 to 0.669 snakes/ha in 2020. Evidence obtained in the present work has allowed to evaluate the main ecological aspects of Z. scalaris and the current state of the population of this invasive snake on the island of Formentera. Results showed that the population is well established in Formentera, but prolonged control campaigns have caused its decline. This study becomes a starting point to improve the management and control programs of invasive snake populations in the Balearic Islands. Long‐term control as well as the improvement of the detection and capture of adult females are strongly recommended to attempt the eradication of Z. scalaris in Formentera.
Technical change, constant rate of exploitation and falling rate of profit in linear production economies
Authors: Basu Deepankar , Orellana Oscar 
Published: April 2023

AbstractCan cost‐reducing technical change lead to a fall in the long run rate of profit if class struggle manages to keep the rate of exploitation constant? In this paper, we derive three results that, taken together, answer this question in the affirmative. First, we identify three properties that new real wage bundles must satisfy to keep the rate of exploitation constant and lead to a falling rate of profit. Second, we derive sufficient conditions for existence of an infinite number of such real wage bundles. Third, we show that, if the initial real wage bundle is such that the maximum price‐labor value ratio is larger than 1 plus the rate of exploitation, then starting from any configuration of technology, there always exists a viable, capital‐using labour‐saving technical change that satisfies the sufficient conditions of the previous result. These results vindicate Marx's claim that if the rate of exploitation remains unchanged then technical change in capitalist economies can lead to a fall in the long run rate of profit.
Synergistic effects of calcium and melatonin on physiological and phytochemical attributes of Dracocephalum kotschyi genotypes under salinity stress
Authors: Vafadar Farinaz , Ehsanzadeh Parviz 
Published: April 2023

AbstractSince regulatory roles of calcium (Ca) and melatonin (MT) in physiological responses of plants to salinity stress are lacking, various Dracocephalum kotschyi genotypes (Bojnord, Urmia, Fereydunshahr, and Semirom) were pretreated with exogenous Ca (5 mM), MT (100 μM), and Ca + MT in the presence of salt (75 mM NaCl). In addition measuring the concentration of phenolic compounds by high‐performance liquid chromatography (HPLC), histochemical evaluations of essential oils and phenolic compounds in glandular trichomes of leaf samples was performed by light microscope. Salt stress reduced shoot fresh (SFW) and dry weight (SDW), leaf area (LA), relative water content (RWC), and maximum efficiency of photosystem II (Fv/Fm), but enhanced total phenolic content (TPC) and total flavonoids content (TFC), phenolic compounds concentrations, 2,2‐diphenylpicrylhydrazyl (DPPH) radical scavenging capacity, electrolyte leakage (EL), proline, and hydrogen peroxide (H2O2) concentrations, and Na+/K+ and essential oils and TPC of the glandular trichomes of leaves in all D. kotschyi genotypes. Foliar spraying of Ca, MT, and particularly Ca + MT on D. kotschyi seedlings improved SFW, SDW, RWC, TPC, TFC, proline, and phenolic compounds concentrations, Fv/Fm, and DPPH radical scavenging capacity, but reduced H2O2, EL, and Na+/K+ in the leaves and essential oils and TPC in the glandular trichomes of all genotypes under both nonstress and salt stress conditions. These findings indicate that the crosstalk between MT and Ca synergistically improves salt tolerance, TPC and TFC, phenolic compounds concentration, and essential oils accumulation in glandular trichomes of different D. kotschyi genotypes.
Sharing

Published: April 2023

AbstractThis paper addresses the status of the act of sharing a message in a social network. Scholars do not agree on what kind of act sharing is and what kind of communicative and illocutionary act is performed when a post is shared. We defend the view that sharing is an act similar to photocopying and distributing a document. Such an act is a basic act that can be used for communicative aims in certain contexts but that is not necessarily communicative. One can repost for several reasons—to manifest agreement or derision, to inform, to please the author, to show activity on social networks, to have an economic return—and only some of them are communicative. However, even when reposters do not perform a communicative act, they are not relieved of every responsibility; in fact, the responsibilities of reposters are like those of the persons who copy and distribute something.

Published: April 2023

AbstractObjectiveTo describe the successful use of endoscopy to visualize and place a soft canine ureteral stent to relieve a chronic nasolacrimal duct (NLD) obstruction in a horse.Animal StudiedA 7‐year‐old, Quarter horse gelding.ProcedureUnder general anesthesia, retrograde nasolacrimal endoscopy was performed using an 8.5 Fr Storz Flex XC ureteroscope through the nasal punctum (NP). An obstructive web of fibrous tissue was visualized approximately 20 cm proximal to the NP. A 0.035″/150 cm hydrophilic guidewire was passed normograde from the ventral lacrimal punctum and used to puncture the stenotic tissue. Then, a 5.0Fr/70 cm open‐end ureteral catheter was threaded normograde over the guidewire and NLD patency was re‐established. The catheter confirmed a NLD length of 30 cm and was then removed. A 5.0Fr/22–32 cm Universa© Soft Ureteral Stent was threaded normograde over the guidewire until the loops of the stent were exposed at each end. The guidewire was removed and the stent loops were sutured in place.ResultsThe stent was withdrawn 1 month after the procedure. Telephone follow‐up with the client reported significant improvement in the amount of ocular discharge and decreased sensitivity around the face and ears.ConclusionEndoscopy is a safe and effective procedure allowing for definitive diagnosis of NLD obstruction and to assist in interventional procedures. Placement of a canine indwelling ureteral stent seems to be an effective alternative treatment option for equine NLD obstruction compared to conventional invasive surgical procedures.

AbstractPurposeThe aim of this study was to bibliometrically analyze the 100 most‐cited articles published in the Veterinary Ophthalmology (VO) journal.MethodsWeb of Science was searched for citations of VO articles published in 1998–2022. Tissue and species studied, and first and last author domicile and affiliation were recorded for the 100 most‐cited articles and descriptively analyzed.ResultsAltogether, the 100 most‐cited VO articles have cited a total of 5483 times. Most commonly, these were devoted to the cornea (23%), multiple tissues (19%), and glaucoma (16%). Studies on dogs (36%), horses (17%), and multiple species (15%) were most often cited. Most first/last authors were from the USA (n = 113), Brazil (n = 13), and France and Germany (n = 7 each), and most frequently affiliated with the University of Florida (n = 36), University of Wisconsin‐Madison (n = 15), and Animal Health Trust, North Carolina State University, and Ohio State University (n = 6 each). KN Gelatt (n = 9), DE Brooks (n = 6), and FJ Ollivier and EO MacKay (n = 5 each) were the most frequent first or last authors. The greatest number of citations was for articles with KN Gelatt (n = 555), FJ Ollivier (n = 411), and DE Brooks (n = 372) as first or last authors. “The comparative morphology of the tapetum lucidum” by FJ Ollivier et al. (2002) is the most frequently cited article in VO history (n = 178).ConclusionsThis study provides insight into the impact of publishing in VO and a more comprehensive understanding of trends and the most influential contributions to VO.
Barosensory vessel mechanics and the vascular sympathetic baroreflex: Impact on blood pressure homeostasis
Authors: Hughes Guto W. , Moore Jonathan P. , Lord Rachel N. 
Published: April 2023

AbstractAn age‐associated increase in arterial blood pressure is evident for apparently healthy humans. This is frequently attributed to stiffening of the central arteries and a concurrent increase in sympathetic outflow, potentially mediated by a reduced ability of the baroreceptive vessels to distend. This is supported, in part, by a reduced mechanical component of the vascular sympathetic baroreflex (i.e., a reduction in distension for a given pressure). Previous characterization of the mechanical component has assessed only carotid artery distension; however, evidence suggests that both the aortic and carotid baroreflexes are integral to blood pressure regulation. In addition, given that baroreceptors are located in the vessel wall, the change in wall tension, comprising diameter, pressure and vessel wall thickness, and the mechanics of this change might provide a better index of the baroreceptor stimulus than the previous method used to characterize the mechanical component that relies on diameter alone. This brief review summarizes the data using this new method of assessing barosensory vessel mechanics and their influence on the vascular sympathetic baroreflex across the lifespan.
Adapting to a new environment: postnatal maturation of the human cardiomyocyte
Authors: Salameh Shatha , Ogueri Vanessa , Posnack Nikki Gillum 
Published: April 2023

AbstractThe postnatal mammalian heart undergoes remarkable developmental changes, which are stimulated by the transition from the intrauterine to extrauterine environment. With birth, increased oxygen levels promote metabolic, structural and biophysical maturation of cardiomyocytes, resulting in mature muscle with increased efficiency, contractility and electrical conduction. In this Topical Review article, we highlight key studies that inform our current understanding of human cardiomyocyte maturation. Collectively, these studies suggest that human atrial and ventricular myocytes evolve quickly within the first year but might not reach a fully mature adult phenotype until nearly the first decade of life. However, it is important to note that fetal, neonatal and paediatric cardiac physiology studies are hindered by a number of limitations, including the scarcity of human tissue, small sample size and a heavy reliance on diseased tissue samples, often without age‐matched healthy controls. Future developmental studies are warranted to expand our understanding of normal cardiac physiology/pathophysiology and inform age‐appropriate treatment strategies for cardiac disease.

Materials Informatics Tools in the Context of Bio-Inspired Material Mechanics
Authors: Luu Rachel K. , Buehler Markus J. 
Published: April 2023

Abstract
The analysis and design of materials is often a slow process that may take weeks, months, or years, and many current material platforms rely on expensive raw material sources that fail to achieve sustainability goals. Meanwhile, bio-inspired Materials Informatics—fueled by emerging techniques such as multiscale modeling, machine learning, and autonomous experimentation—is transforming the way materials are understood, discovered, developed, and selected. The impact of these tools is particularly noteworthy since they can be used to develop materials with fewer resources and with greater societal impact. A field that would strongly benefit from the use of Materials Informatics tools is that of structural biological materials, where mechanical properties are crucial for biological and engineering properties for species survival such as fracture-resistant armor against predators, elastic recovery for repeated loadings, or mechanical actuation capacity. Generations of researchers have studied biological materials for their fascinating structure–property relationships that make up their impressive properties, including mechanical resilience. Despite the accumulation of scientific knowledge, relatively little has been translated to generating engineered bio-inspired materials. Addressing this gap, emerging Materials Informatics tools can now be used to make use of legacy data, newly collected empirical observations, and predictive models to make significant advances in this field.
Numerical Research on the Heat-Transfer Enhancement of Printed Circuit Heat Exchanger in the Presence of Pulsating Flow
Authors: Lu Peng , Wei Jian , Yan Xiaodie , Yang Qinshan 
Published: April 2023

Abstract
This paper presents a numerical investigation on the flow and heat-transfer characteristics of liquid lithium and helium in printed circuit heat exchanger (PCHE) channels with pulsating flow introduced. The effects of the mass flowrate of helium, frequency, and amplitude of pulsating flow were examined, respectively. The findings indicate that the introduced pulsating flow has a positive effect on heat transfer at a lower Reynolds number. With the increase of pulsating frequency, the heat-transfer enhancement may decline, and the pressure drop is reduced, with Colburn factor (j) and Fanning friction factor (f) varying marginally. In the flow state with enhanced heat transfer, keeping a lower pulsating frequency, the heat-transfer enhancement ratio E(h) exhibits an approximately linear increase with the pulsating amplitude. Meanwhile, the average pressure drop, Colburn factor (j) and Fanning friction factor (f) also increase with the amplitude, with the fluctuation amplitude of each parameter directly proportional to the amplitude.
A Compressible, Coupled Three-Dimensional/One-Dimensional Flow Solution Method for the Seamless Simulation of Centrifugal Pumps and Their Piping
Authors: Munsch Pascal , Lehr Christian , Brümmer Andreas , Skoda Romuald 
Published: April 2023

Abstract
A compressible finite volume Navier–Stokes flow solver is coupled to a method of characteristics for the seamless turbulent flow simulation of entire pump systems. For the pump, three-dimensional (3D) simulations including cavitating flow conditions are performed, and the piping is treated one-dimensional (1D) by a method of characteristics. Thus, classical boundary conditions at the suction and pressure pipe of the 3D computational domain of the pump are substituted by a two-way coupled 1D piping simulation method. Particular emphasis has been placed on the non-reflecting properties of the 3D–1D coupling interface. For validation, in-house experiments are performed on a low specific speed centrifugal pump in a closed-loop facility. For cavitating flow conditions, excitation on the pump's pressure side by rotor–stator interaction is enhanced over a broad frequency spectrum due to collapsing voids. The suction side piping is shielded by void regions within the blading from the excitation on the pump's pressure side, leading to an acoustic decoupling of the suction side. These experimental observations are reproduced by the new seamless simulation method. In particular, the measured pressure amplitudes are well reproduced for a broad frequency spectrum, at several piping positions, and for a variation of the flow rate and the cavitation intensity. Remaining deviations to experimental data are traced back to the omission of structural compliance and uncertainties regarding the pressure side piping modeling, which will be addressed in future studies.
