Published: March 2023

AbstractSynthetic polymer polyvinyl alcohol (PVA) and Polyvinyl pyrrolidone (PVP) was utilised as a blend with hydrogel and natural plant leaf extract Ormocarpum cochinchinense (OC). Its biodegradability and biocompatibility, have received more attention with regard to the wound dressing applications. In the present work synthesized bio composite film containing Ormocarpum cochinchinense (OC), polyvinyl alcohol (PVA) and polyvinyl pyrrolidone (PVP) was characterized using Fourier transmission infrared spectroscopy (FTIR), X‐ray diffraction spectroscopy (XRD), Field emission Scanning electron microscopy (FESEM) and Energy dispersive X‐ ray spectroscopy (EDS) analysis. Swelling studies and antimicrobial activities were also carried out to ascertain the credibility of the blended mixture. As a result, they offer a promising source of information for studies on wound dressings.

AbstractDevelopment of catalysts using natural feedstock is the need of the current era, and accordingly, we have developed a new ligand N‐(2‐hydroxynapthylidene)‐L‐leucienyl‐4,6‐O‐ethylidene‐β‐D‐glucopyranosylamine using natural occurring D‐glucose and L‐amino acid. It interacts with several bio‐relevant metal ions like iron, copper, zinc, etc., but its association with cupric ions is immune to pH (4.2–9.1) change. In‐situ copper‐catalyzed reactions have been proven to be pivotal in many important organic syntheses, including imidazo[1,2‐a]pyridines, which is one of the important precursors of many drug molecules. Catalytic synthesis of imidazo[1,2‐a]pyridines requires high catalyst loading, hazardous solvent, high temperature, and long reaction time, which are major drawbacks towards green synthetic methodology. Interestingly, our glycoconjugate‐derived cupric complex catalyzes the reactions among aldehydes, 2‐aminopyridines, and terminal alkynes under the solvent‐free condition to afford one‐pot synthesis of imidazo[1,2‐a]pyridines and 23 derivatives have been reported in good to excellent yields (53–93 %) using lower reaction time, temperature, and catalyst loading compared to other reports on similar reactions. Hence, our approach enhances the green methodology towards the catalytic synthesis of imidazo[1,2‐a]pyridine derivatives.

AbstractLithium metal batteries (LMBs) are promising for next‐generation high‐energy‐density batteries owing to the highest specific capacity and the lowest potential of Li metal anode. However, the LMBs are normally confronted with drastic capacity fading under extremely cold conditions mainly due to the freezing issue and sluggish Li+ desolvation process in commercial ethylene carbonate (EC)‐based electrolyte at ultra‐low temperature (e.g., below −30 °C). To overcome the above challenges, an anti‐freezing carboxylic ester of methyl propionate (MP)‐based electrolyte with weak Li+ coordination and low‐freezing temperature (below −60 °C) is designed, and the corresponding LiNi0.8Co0.1Mn0.1O2 (NCM811) cathode exhibits a higher discharge capacity of 84.2 mAh g−1 and energy density of 195.0 Wh kg−1cathode than that of the cathode (1.6 mAh g−1 and 3.9 Wh kg−1cathode) working in commercial EC‐based electrolytes for NCM811‖ Li cell at −60 °C. Molecular dynamics simulation, Raman spectra, and nuclear magnetic resonance characterizations reveal that rich mobile Li+ and the unique solvation structure with weak Li+ coordination are achieved in MP‐based electrolyte, which collectively facilitate the Li+ transference process at low temperature. This work provides fundamental insights into low‐temperature electrolytes by regulating solvation structure, and offers the basic guidelines for the design of low‐temperature electrolytes for LMBs.
Putative hydroid symbionts recorded by bioclaustrations in fossil molluscan shells: a revision and reinterpretation of the cecidogenusRodocanalis

Published: March 2023

AbstractThe fossil record yields a peculiar phenomenon in different kinds of molluscan shells: bioclaustrations formed around (epi)symbionts during growth of the hosts' shell margin. Four morphologies, two of them formerly considered bioerosion traces, are here united in the parataxonomy of bioclaustration structures under the revised cecidogenusRodocanalis. These are: (1) simple linear grooves (Rodocanalis lineariscsp. nov.) formed below the periostracum in Pleistocene to Recent endobenthic bivalves; (2) series of distally ramifying grooves (Rodocanalis runicus) in Silurian orthoconic nautiloids; (3) irregular networks of grooves (Rodocanalis reticulatus) in Jurassic to Cretaceous bivalves and gastropods; and (4) regular reticulate networks (Rodocanalis geometricuscsp. nov.) in Jurassic to Cretaceous gastropods. The linear grooves might be associated with commensal worms, while multiple lines of reasoning point towards hydrozoan symbionts in the case of the branched and anastomosing grooves. After the hydrozoan larva settles and the first polyp becomes fixed on the calcareous ostracum at the shell margin, the process of bioclaustration commences when the periostracum surrounds the base of the polyp, which moves towards the external shell surface, while the hydrorhizae develop in the only possible direction: towards the shell growth margin. This enables new polyps to originate at the shell edge by budding, while the bioclaustration of the stolonial hydrorhizae advances. We consider the nature of this symbiotic relationship as mutualism, with the hydrozoan symbiont taking advantage of the host's feeding current or food debris, and the molluscan host profiting from the defensive capability of the hydrozoan's cnidocysts.
Understanding the technical and social paradoxes of learning management systems usage in higher education: A sociotechnical perspective
Authors: Ali Mohammed , Wood‐Harper Trevor , Wood Bob 
Published: March 2023

AbstractThe recent COVID‐19 pandemic has created an unprecedentedly complex situation and wicked problem in the education domain. This has forced educators and learners to study from home using unfamiliar pedagogical typologies and technologies in order to adapt to the new work routine. This research contributes to theory and practice by adopting a sociotechnical approach (STS) to understand the technical and social implications of learning management systems (LMS) to inform pedagogical development. A qualitative approach is adopted, and semi‐structured interviews are conducted across two university cases with 40 academics and students to capture their perceptions of LMS usage. We found that technical paradoxes present a barrier to pedagogical development in the transition from blended learning environments to remote ones, where many wicked and unprecedented challenges emerge from learning remotely during a pandemic, while social paradoxes arise from cultural issues such as user resistance that impede the university's pedagogical goals and visions.
Distribution and straying of minijack Chinook Salmon released from a captive broodstock hatchery program
Authors: Pearsons Todd N. , Graf Peter J. , Taylor Timothy N. 
Published: March 2023

Abstract

Objective
Production of Chinook Salmon Oncorhynchus tshawytscha in hatcheries can unintentionally produce large numbers of age-1 males, termed "minijacks," which pose ecological and genetic risks to target and nontarget populations. We evaluated the postrelease distribution of minijacks produced in a hatchery captive broodstock program targeting the White River in the Columbia River basin between 2010 and 2015.

Methods
Fish were passive integrated transponder (PIT)-tagged in the hatchery (n = 218,555), and databases were searched to determine movement behavior and final detections on fixed PIT tag antenna arrays during the year in which they were released.

Result
Two main movement behaviors were detected: (1) residuals, which moved solely within the subbasin of release; and (2) migrants, which moved downstream into the Columbia River and then reascended the Columbia River in the year of release. Minijacks that reascended fish ladders in the Columbia River were most often detected at Rock Island and Bonneville dams, the nearest and furthest detection locations downstream of the Wenatchee River. Minijacks were last detected in all locations where spring Chinook Salmon spawn in the Wenatchee River subbasin (seven tributaries and one main-stem area) and also in the Entiat River (an adjacent watershed); minijacks in eight of the nine locations were considered strays. Estimates of minijacks that strayed outside of the White River were between 61% and 100% annually and were influenced by release location. Minijacks were also more abundant than males of all older ages in some of the tributaries during some years. In addition, they were detected in these tributaries during periods when anadromous adults migrate into spawning areas and when spring Chinook Salmon spawn.

Conclusion
The large amount of minijack production and the spatial and temporal overlap could pose genetic and ecological risks to both target and nontarget populations and particularly high straying poses risks to the maintenance of between-population genetic variability.
Dynamic Changes in Pre‐Service Language Teacher Well‐Being in the Classroom Ecology: A Micro Approach
Authors: Sak Mehmet , Gurbuz Nurdan 
Published: March 2023

AbstractAlthough language teacher well‐being has been the focus of growing attention in recent years, there is little known of its dynamic and contextually dependent nature. Integrating the complex dynamic view of well‐being with an ecological orientation, this classroom‐based study examined the micro‐scale changes in pre‐service language teacher well‐being and the reasons for such changes using data from three pre‐service English‐as‐a‐foreign‐language (EFL) teachers in Türkiye. The individual trajectories of well‐being were tracked in a particular class over 4 weeks through self‐ratings of well‐being at 10‐minute intervals during the lectures, journal entries, interviews, and stimulated recall sessions on individual microteachings. The findings suggest that the experience of pre‐service language teacher well‐being in the classroom ecology remains subject to inter and intraindividual variability over time, displaying nonlinear trajectories not only within sequences of single lessons but also from one lesson to another in response to a host of personal and contextual factors. These findings imply that pre‐service language teacher well‐being is not static, but instead is enhanced and reduced at particular moments in the classroom as a result of the interplay of a myriad of variables. We end with a call for more research into micro‐scale changes in teacher well‐being within applied linguistics and beyond.

Published: March 2023

AbstractHalf‐sandwich iridium complexes of the type [(η5‐C5Me5){(NHC)E}IrCl] (E=P, As) were prepared by the reactions of N‐heterocyclic carbene (NHC) adducts of trimethylsilylphosphinidene and trimethylsilylarsinidene, (IDipp)ESiMe3 and (IMes)ESiMe3, with [(η5‐C5Me5)IrCl2]2 (IDipp=bis(2,6‐diisopropylphenyl)imidazolin‐2‐ylidene; IMes=1,3‐bis(2,4,6‐trimethylphenyl)imidazolin‐2‐ylidene). The molecular structure of [(η5‐C5Me5){(IDipp)As}IrCl] was established by X‐ray diffraction analysis, affording the first structurally authenticated NHC‐arsinidenide complex with a short Ir−As bond length that reveals a significant degree of metal‐arsenic π‐interaction as also confirmed by theoretical calculations.
Consciousness as the Source of Purposeful Leadership
Authors: Nader Tony , Maheshwari Anil K. 
Published: March 2023

AbstractStrong, focused, and inclusive leadership is of the essence in articulating and solving the overwhelming problems of climate change, social inequality, bio-extinction, and more. Many researchers have highlighted the need to design new integrative approaches to gather the collective energies of humanity to face those challenges (Datar et al., Rethinking the MBA: Business education at a crossroads. Harvard Business Press, 2010). Purposeful Leadership based on a higher purpose (Quinn & Thakor, The economics of higher purpose: Eight counterintuitive steps for creating a purpose-driven organization. Berrett-Koehler Publishers, 2019), a deep purpose (Gulati & Adam, Deep purpose: The heart and soul of high-performance companies. Harper Business Press, 2022), a sustainable purpose (Polman & Winston, Net positive: How courageous companies thrive by giving more than they take. HBS Press, 2021), and total interconnectedness (Tsao & Laszlo, Quantum Leadership, Stanford University Press, 2019) is another way proposed to harness the integrative self-awareness of people in organizations. We propose that purposeful leadership emerges from the higher consciousness of leaders and managers (Maheshwari, Journal of Management, Spirituality & Religion 18:77–91, 2021; Nader, One Unbounded Ocean of Consciousness. Aguilar, 2021). The foundational Vedic message ofYogasthah kuru karmani, or “Established in Consciousness, perform action” (Maharishi Mahesh Yogi, The science of being and art of living, 1963) from Bhagavad Gita, implies that highly developed consciousness of individuals leads to more evolutionary leadership (Harung et al., Leadership Org Dev J, 16:44–59, 1995). This chapter will discuss purpose-driven leadership and purpose-driven organizations (Quinn, & Thakor, The economics of higher purpose: Eight counterintuitive steps for creating a purpose-driven organization. Berrett-Koehler Publishers, 2019) in the context of developing a theory of organizational purpose (Morrison & Rota, Academy of Management Review, 2021), which describes the principal values and drivers of purpose-driven organizations, and how such organizations may be better positioned for solving the problems facing humanity. It will also describe how regular practice of transcending can help develop the consciousness of leaders and managers and help clarify their deeper purposes.
Sexual Aspects of the Female Pelvic Floor
Authors: Westerik-Verschuuren Liesbeth , Lutke Holzik-Mensink Marjolijn , Wieffer-Platvoet Marleen , van der Velde Minke 
Published: March 2023

AbstractThis chapter is devoted to the pelvic floor (PF). Maternity care has always considered the PF muscles an essential part of the birth and its disturbances. Gradually, the pelvic floor became a vital element for both sexual pleasure and sexual problems. This chapter will start by explaining its role in posture and movement, and sexuality and delineate the differences between the normotonic, the hypotonic, and the hypertonic pelvic floor and their influences on sexuality. The chapter also gives some elementary education on assessing pelvic floor function. After explaining the PF concerning pregnancy and birth, the chapter will address aspects of prevention and prehabilitation. In other words, this chapter will also deal with how to optimally prepare the pregnant woman for a relaxed birth with as low as possible negative consequences regarding vaginal laxity or pelvic floor prolapse. For the severe pelvic floor disturbances and their implications on sexuality and quality of life, the reader is recommended to look at Chap. 16.This chapter is part of ‘Midwifery and Sexuality’, a Springer Nature open-access textbook for midwives and related healthcare professionals.
Sexual Aspects of High-Risk and Complicated Pregnancy
Authors: Simetinger Gabrijela , Gianotten Woet L. 
Published: March 2023

AbstractIn a healthy pregnancy, the best response to sexual insecurity is reassurance and telling the couple that they can continue to be sexually active. When the situation gets complicated, things can be different. This chapter elaborates on the sexual risks in conditions such as premature birth, shortened cervix, placental dysfunction, and multiple gestation. It will delineate the relationship between various sexual activities and their potential influence on the uterus and the pregnancy. The chapter will also address how to communicate when specific sexual acts should be discouraged (or forbidden) and simultaneously give room for other sexual acts, in other words: the sexual do’s and don’ts. Midwives and HCPs must be aware of the cultural taboos between the woman and the couple regarding sexuality and pregnancy. It is a common finding in research that patients have many questions about sex but do not ask them. The consequence is that the professional must anticipate when providing information, as it were, by ‘answering the not-asked questions’. This chapter provides the background information needed to do just that in high-risk and complicated pregnancies.This chapter is part of ‘Midwifery and Sexuality’, a Springer Nature open-access textbook for midwives and related healthcare professionals.
Sexual Aspects of Problematic Lactation
Authors: Uslu Dilek , Debonnet Serena 
Published: March 2023

AbstractLactation can be an extremely beneficial factor in the bonding between mother and baby and can, at the same time, also impair the bond between the woman and her partner. On the other hand, breastfeeding can last longer when the partner is supportive. Therefore, to properly succeed, it is crucial to approach breastfeeding using a couple’s strategy. Good lactation is, for many women, also kind of proof of good motherhood. From that perspective, developments like pain during feeding, mastitis, or early breastfeeding cessation can easily have consequences for female identity and the couple’s sexual relationship.This chapter will elaborate on those areas. It will also provide information on breastfeeding in diseases like multiple sclerosis and spinal cord injury, on breastfeeding after breast surgery and when there has been depression or abuse in the past. A small piece will elaborate on induced lactation in the woman who did not carry the pregnancy.This chapter is part of ‘Midwifery and Sexuality’, a Springer Nature open-access textbook for midwives and related healthcare professionals.
Relevant (Sexual) Aspects of Cultural Differences
Authors: Atallah Sandrine , Redón Aida Martín 
Published: March 2023

AbstractCulture is one of the most important elements influencing the sexual lives of people. Factors like traditionalism, religion, polygamy, machismo, and feminism influence sexuality and cultural ideas about motherhood and sex roles. This chapter focuses on those cultural aspects. Cultural differences exist not only by merit of geographical distance since cultures get intermingled through economic migration, political refugees, and global traffic. Even in midwifery, there are significant cultural differences between one country and another. In some countries, midwives independently guide childbirth at home, whereas, in other countries, the law prohibits such an approach. In some countries, the midwife provides postpartum contraception, whereas, in others, they don’t.This book is written in English and focuses relatively strongly on Western maternity care. It certainly has a European touch since most authors work in Europe. An advantage of Western and Northwestern Europe is the more open and pragmatic approach to discussing sexuality. While sexuality is essential everywhere, some basic health and luxury seem needed before it becomes relevant to tackle the problematic aspects of sexuality. We believe this book to be precious to midwives in middle- and high-income countries (Atallah et al., J Sex Med 13:591–606, 2016). On the other hand, much of the information will also be handy for urban midwives in low-income countries.This chapter is part of ‘Midwifery and Sexuality’, a Springer Nature open-access textbook for midwives and related healthcare professionals.
Sexual Aspects of Pregnancy
Authors: Polona Mivšek Ana , Tomai Xuan-Hong 
Published: March 2023

AbstractEspecially during the first pregnancy, many changes occur in the woman and in the relationship with her partner. This chapter will describe the wide range of elements influencing sexuality and intimacy in pregnancy, according to the pregnancy trimesters. It will start with the physical changes and continue with psychological issues.Sexual desire can change in different directions and is influenced by physical and psychological factors like fear (for miscarriage, pre-term birth, etc.), changing appearance and sense of self. Both pregnancy and sexual arousal are characterised by hypercongestion of the internal and external genital organs and the breasts. The pregnancy’s physiology can, on the one hand, facilitate sexual arousal. The accumulating effect of sexual arousal and the existing hypercongestion can, on the other hand, cause pain in the breasts and the vulvar area and therefore diminish arousal. In the last trimester of pregnancy, the quality of orgasm can change from clonic contractions to tonic (and can therefore be painful).Moreover, also partners deal with pregnancy and change differently, depending on their personal experiences, earlier quality of this relationship, upbringing and cultural context. The chapter focusses on the couple, not just the woman.This chapter is part of ‘Midwifery and Sexuality’, a Springer Nature open-access textbook for midwives and related healthcare professionals.
The Markov gap in the presence of islands
Authors: Lu Yizhou , Lin Jiong 
Published: March 2023

Abstract
The Markov gap [1], namely the difference between reflected entropy and mutual information, is explicitly computed in the defect extremal surface model, JT gravity, and the generic 2d extremal black holes, in vacuum states. The phases that contain various island contributions are considered, and their existence is carefully checked. Moreover, we show explicitly how the Markov gap originates from the OPE coefficient of the boundary CFT. And, as a generalization of [1], the lower bound of the Markov gap is given by $$ \frac{C}{3} $$

C
3

log 2 times the number of EWCS boundaries on minimal surfaces. We propose a boundary way of counting the lower bound for the Markov gap, which states that the lower bound is given by $$ \frac{C}{3} $$

C
3

log 2 times the number of gaps between two boundary regions in vacuum states. We discuss the limitation and possible generalization of the boundary counting, and its relation to tripartite entanglement.
