Perturbations by lower order terms do not destroy the global hypoellipticity of certain systems of pseudodifferential operators defined on torus
Authors: Ferra Igor Ambo , Petronilho Gerson 
Published: April 2023

AbstractWe introduce a new class of smooth pseudodifferential operators on the torus whose calculus allows us to show that global hypoellipticity with a finite loss of derivatives of certain systems of pseudodifferential operators is stable under perturbations by lower order systems of pseudodifferential operators whose order depends on the loss of derivatives. We also present some applications.

AbstractBackgroundBipolar disorder's (BD) potential endophenotypes include neurological soft signs (NSS) and neurocognitive disorders (ND). Few research, meanwhile, has coupled NSS and ND as combined endophenotypes of BD.ObjectThis study intends to investigate NSS and ND and compare their differences in euthymic patients with bipolar disorder (EBP), their unaffected first‐degree relatives (FDR), and healthy controls (HC). Additionally, search for potential endophenotypic subprojects of NSS and ND and construct and verify a composite endophenotypic.MethodsThe subjects were all Han Chinese and consisted of 86 EBP, 81 FDR, and 81HC. Cambridge Neurological Inventory and MATRICSTM Consensus Cognitive Battery tested NSS and ND independently.ResultsAll three groups displayed a trapezoidal distribution of NSS levels and cognitive abnormalities, with EBP having the most severe NSS levels and cognitive deficits, followed by FDR and HC. Among them, motor coordination in NSS and Information processing speed (IPS), Verbal learning (VL), and Working memory (WM) in neurocognitive function are consistent with the traits of the endophenotype of BD. The accuracy in differentiating EBP and HC or FDRs and HC was higher when these items were combined as predictor factors than in differentiating EBP and FDR.ConclusionThese results provide more evidence that motor coordination, IPS, VL, and WM may be internal characteristics of bipolar disease. When these characteristics are combined into a complex endophenotype, it may be possible to distinguish BD patients and high‐risk groups from normal populations.

AbstractThis study aimed to evaluate the effects of donor age on lipid metabolism during in vitro maturation (IVM) of pigs cumulus‐oocyte complexes (COCs). We evaluated transcript levels of genes, the percentage of ooplasm occupied by lipid droplets (LD) and evaluated DNA methylation in COCs from sows and prepubertal gilts. Transcript levels of six genes (ACACA, ACSS2, FASN, FABP3, SLC27A4, PLIN2), which were analyzed in cumulus cells (CCs), increased after 44 h of IVM in the sow group. In the gilt group, only FASN expression increased, while NR3C1 expression decreased after IVM. The measurement of LD in oocytes showed an accumulation of lipids in sow oocytes during IVM, while gilt oocytes showed a decrease in LD. FABP3 and NR3C1 methylation patterns exhibited a demethylation pattern in CCs and oocytes from gilts and sows and showed statistical differences between groups. CCs from sows had a better capacity to change transcription levels of the major genes involved in lipid metabolism during IVM than CCs from gilts. This difference may be involved in accumulation of lipids, acquisition of competence, and maturation of enclosed oocytes. Our results contribute to a better understanding of mechanisms involved in lipid metabolism and acquisition of competence in porcine COCs.
Reflexivity in nonprofit management research: A reflection on the role of self as researcher
Authors: Akingbola Kunle , Brunt Carol 
Published: April 2023

AbstractDrawing on three diverse case studies, the research note illustrates the use of reflexivity as an advantageous research strategy and its implications for nonprofit management and leadership research. Reflexivity is both a product and a process, that highlights a mutuality between researcher and participants in creating collaborative knowledge through intentional information exchange. For nonprofit organizations, reflexivity offers a research method that extends the sector's community‐based participatory approach. On the surface, nonprofit organizations are comfortable with diverse research methodologies. The multifaceted systems, interactions and processes that characterize nonprofit organizations require researchers to incorporate standard methodologies alongside more complex dimensions of participants' lived experiences. This paper highlights why reflexivity is a viable social constructivist research method relevant to the nonprofit management research collaborative approach.

Published: April 2023

AbstractAimWe explored the performance of demographic characteristics, physiological state, cognitive function, sensory function, and biomarkers when used as predictors of frailty for patients with schizophrenia.DesignA cross‐sectional study design was adopted.MethodsDemographic data and data on physiological state, cognitive function, sensory function, biochemical indices, and frailty status of patients with schizophrenia were collected. The data were analysed using descriptive statistics, a chi‐square test, one‐factor analysis of variance, and logistic regression.ResultsThe results revealed that frailty was prevalent among patients with lower educational attainment, longer hospital stay, higher skeletal muscle mass, higher basal metabolic rate, lower cognitive function, the use of tranquillisers and sleeping pills, and the use of assistive equipment as well as having fallen in the past year. In addition, cognitive function (p < 0.05), use of a wheelchair (p < 0.05), and use of an assistive walker (p < 0.001) were used as predictors of frailty condition of patients with schizophrenia.Patient ContributionPatients with schizophrenia have higher risk of having complications than patients with other chronic illnesses. Therefore, medical staff should regularly assess the levels of frailty risk to help patients with schizophrenia.
Synthetic polymers as bone engineering scaffold

Published: April 2023

AbstractDamage or loss of the bone tissue leads to mobility decline contributing to one of the major issues of human well‐being. Tissue engineering is used to recover fractures and damaged parts of the bone tissue. Various biomaterials and scaffolds have been evaluated for regeneration of hard tissues, however, polymers are the most frequently required biomaterials for the improvement of synthetic bone scaffolds due to their suitable mechanical properties and similar degradation rates to the proteins in hard and soft tissues. Synthetic polymeric materials in bone replacement have several advantages because their physical characteristics can be designed according to their application and their composition can be changed easily. On the other hand, the high adaptability, tenability, and biocompatibility of synthetic materials have received considerable acceptance in the field of tissue engineering. This article presents an update on materials for the fabrication of scaffolds in bone tissue engineering; in addition, we provide information of different kinds of scaffolds and their application usage for hard tissue regeneration.
An equivalent RBDO method under the hybrid of fuzzy and interval variables in the worst case

Published: April 2023

AbstractIn the reliability‐based design optimization (RBDO) problems of structures or systems, only a single type of variable involving is rare, and most of time are hybrid variables. Random variables are often used to describe uncertainty, and these random variables can usually be described by certain probability distributions. However, in practice, the probability distributions of some random variables are difficult or even impossible to be obtained, or the obtained probability distributions may be inaccurate, and can only be roughly described by fuzzy values or intervals. Therefore, this paper is committed to solving RBDO problems under the hybrid of fuzzy variables and interval variables. Firstly, the RBDO model of the structure under the hybrid variables is established. Secondly, the fuzzy variables are transformed to random variables according to entropy invariance. Finally, RBDO is carried out based on sequential single‐loop method in the worst case. A numerical example is presented to illustrate the feasibility of the proposed method.
Conceptualising Indigenous Law

Published: April 2023

AbstractLaw is the most immersive of concepts in an Indigenous cultural context. It is a nuanced schema for human existence, and goes beyond a system of justice or governance as might be the conventional and western understanding of law, to shape and give meaning to all aspects of life. Indigenous Law provides the logic and rationale for life, as inclusive of ancestral and creator beings, humans and non-humans, the place world and all types of natural phenomena. Law instates the relations between all emplaced elements and beings.This opening chapter serves to establish the context and scene for a sensitive and respectful discussion of Indigenous Law, acknowledging the varied language that is used around the world to describe and analyse different iterations of Indigenous Laws, ranging from Law, customary law, knowledge, tradition, religion and spiritualism.
Testimonies of Yanyuwa Law and Kincentric Order

Published: April 2023

AbstractIn this chapter we present a demonstration of Indigenous Law in practice at a local level, a detailed account of an oral testimony given by Yanyuwa elder Old Arthur Narnungawurruwurru (Old Arthur). This example demonstrates how key individuals within the Yanyuwa community would come together to make collectively agreed-upon decisions, in alignment with the practice and continuation of Law. The story as outlined in this chapter was shared with one of the authors (Bradley) by Old Arthur himself, at the request of his niece, and co-author Annie a-Karrakayny, a senior Yanyuwa Law woman. The testimony relates to matters of the Dreaming, kinship, succession, land and sea rights and political decision-making processes. In the first part of this chapter, we present this account of Law piece by piece, first in Yanyuwa language and then in translated English.This chapter shows the many ways in which Law has complexity. This is a vision of Indigenous cultures and their Laws as highly adept at accommodating, resisting and negotiating internal pressures, but even more so the external pressures that distinguish settler colonial and Indigenous relations.
Introduction: The Myth of Protection
Authors: Spitka Timea 
Published: April 2023

AbstractTraditional notions of security have focused on the protection of the state or ethno-religious groups. To what extent does national or group security provide protection for all civilians? To what extent is the international community responsible for protection of civilians? International protection norms namely Responsibility to Protect (R2P) have given precedence to human security and civilian protection over state sovereignty. Although human security is part of today’s discourse and has evolved into an international norm, it has not been operationalized into protection of civilians in a divisive context. This introductory chapter examines the dichotomies of national and international protection related to civilian vulnerabilities, including war atrocities, apartheid and exploitation. It examines the protection of civilians in a single conflict-ridden case; Israel/Palestine, to illuminate on the gaps in the current analysis of security and protection. The chapter analyses Israeli, Palestinian and international security strategies as they apply to the protection of civilians. Examining protection versus national security strategies, this study reveals some of the realities and myths about national and international protection within contested spaces.
Children as Victims and Activists in the Israeli/Palestinian Conflict
Authors: Spitka Timea 
Published: April 2023

AbstractPalestinian and Israeli children and teenagers play centre stage in the conflict as victims, activists, perpetrators of violence and as tools used in national propaganda campaigns. This chapter focuses on the national protection principles and practices of Palestinian and Israeli children and teenagers. Teenagers are commonly caught up in national campaigns, trained in using weapons, exploited for risky activism, vigilantism and acts of terror. Palestinian children and teens, particularly those living in Gaza, East Jerusalem and West Bank are not only vulnerable during escalations but are subject to exploitation, detentions and severe security measures. This chapter explores the safety and well-being of children and teens under the Israeli and Palestinian authorities.
Inclusive Protection: Gender and Resilience
Authors: Spitka Timea 
Published: April 2023

AbstractDespite the appearance of gender sensitivity and the efforts of NGO’s and INGO’s, gendered human security remains superficial without true inclusive participation in peace process, security efforts, with marginal impact on the protection of the most vulnerable populations particularly in Gaza, East Jerusalem and the West Bank. This chapter analyses the implementation of UNSC Resolution 1325 and causes behind the absence of operationalization of priorities of Women, Peace and Security (WPS) within the Israeli/Palestinian conflict. Focusing on gender, this chapter examines the gaps in the operationalization of protection norms under Israeli, Palestinian and international authority and provides a potential roadmap for inclusive protection.
Merleau-Ponty and Standpoint Theory
Authors: Harrison Rebecca 
Published: April 2023

AbstractOver the course of its history, feminist standpoint theory has encountered a number of problems which reveal divisions among its supporters over certain fundamental philosophical commitments. This chapter sketches a phenomenological account of perception that can begin to address these problems, drawn largely from Maurice Merleau-Ponty’s Phenomenology of Perception. Merleau-Ponty can help us resolve these issues by providing an account of perspectival perception wherein a multiplicity of different perceptual standpoints all nonetheless put us in touch with a single external world, and in which some standpoints may be better than others when it comes to accessing certain features of this world. For Merleau-Ponty, the proliferation of standpoints need not lead us into an unacceptably relativistic framework, as long as we are able to conceive of each of these standpoints as giving whoever occupies it access to some particular aspect of a singular, real, shared world.
The Life and Afterlife of Phenomenology in Archaeological Theory and Practice
Authors: Moyes Holley 
Published: April 2023

AbstractIn 1994, Christopher Tilley published his treatise, A Phenomenology of Landscape: Places, Paths and Monuments, that stimulated what has been referred to as the phenomenological “moment” in archaeology. Invoking Heideggerian phenomenology and following Merleau-Ponty, Tilley’s methods met with harsh criticism among many in the archaeological community. To some, Tilley’s hyper-interpretive methods lacked rigor and had the problem of imposing one’s own feelings and observations onto the people of the past without considering the cultural contexts and symbolic meanings imbued in past perceptions of landscapes. Tilley’s work leans heavily on embodiment, taking a humanistic approach that relies on the investigator’s own perceptions as the central source of data used for archaeological interpretation. Despite heavy criticism, his work prompted numerous revisions of his ideas and generated more nuanced approaches. Under criticism, explicitly phenomenological approaches soon gave way to the “Archaeology of the Senses,” which rests heavily on idealist approaches and the role of memory in sensorial experience. Still, the instigator’s own embodied experience with an emphasis on self-reflexivity remains the most important tool for interpretation. Though this is rarely made explicit in sensory studies, it is the underlying assumption in archeological reconstructions, virtual reality simulations, and thick descriptive narratives, all methods employed in these works. The question is, can a more rigorous methodology be developed that legitimizes the use of self as a tool for archaeological interpretations without being construed as ahistorical, homogenizing, or as a Western modernist universalism? Can we hope to understand the life experiences of people from the past using the only available tool at our disposal—ourselves? Cognitive science offers us a way forward in creating a more grounded phenomenological approach.
Anthropological Phenomenology and the Eventive Ground
Authors: Stephan Christopher , Throop C. Jason 
Published: April 2023

AbstractThis chapter theorizes the phenomenological potential of anthropology through an examination of what we will call the “eventive ground” of ethnographic knowledge. Though anthropologists and phenomenologists have reacted to one another’s work, including the now famous early correspondence between Husserl and Levy Bruhl (see Sato, 2014; Throop, 2018), it has only been over the past few decades that some anthropologists began to distinguish a genre of a distinctively ‘phenomenological anthropology’ (Desjarlais & Throop, 2011; Katz & Csordas, 2003; Ram & Houston, 2015). Anthropologists have applied and extended phenomenological theory in several respects. By attending to the cultural and social contexts—the conditions of possibility—within which phenomena variously disclose themselves, anthropologists have significantly contributed to research in intersubjectivity and genetic phenomenology. Likewise, anthropologists have frequently drawn from and contributed to the phenomenology of perception, the senses, self-experience, embodiment, emotion, affect, mood, politics, and ethics.
Bibliometric Analysis of the Phenomenology Literature
Authors: Contreras Kallens Pablo , Yoshimi Jeff 
Published: April 2023

AbstractMore has been written about phenomenology than could possibly be read in a single person’s lifetime, or even in several lifetimes. Despite its unwieldy size, this vast “horizon” of literary output has a tractable structure. We leverage the tools of bibliometrics to study the structure of the phenomenology literature, and test several hypotheses about it. We create an author-wise co-citation network, a graph of nodes and connections, where each node corresponds to an author who has written a document with the word “Phenomenology” in it, and where two nodes are connected if the corresponding authors have cited each other. By applying clustering algorithms and other techniques to this network, certain structural features of the field emerge. The main areas of research since 1970 conform fairly well to an intuitive understanding of the literature, though there are some surprises.
Heideggerian Phenomenology
Authors: Zangeneh Hakhamanesh 
Published: April 2023

AbstractWas Heidegger a phenomenologist? Can his work be considered phenomenological? Can he be affiliated with phenomenology in some way beyond biographical contingencies? The answer to these questions is neither obvious nor uncontroversial. In the following, I propose to address these questions by starting from a typology of the literature on Heidegger. My hope is that with such an overview it will become easier to identify a specifically phenomenological (as opposed to hermeneutical, deconstructionist, etc.) development in and of his work.
Archery Rites: Remaking Confucian Rites
Authors: Kenderdine Sarah , Hibberd Lily , Shaw Jeffrey , Chang Tsong-Zung , Hou Yumeng 
Published: April 2023

AbstractRitual archery has a long and vital history in Chinese civilization. This chapter examines the current reenactment and digital reconstruction of the specific tradition of the Archery Rites embedded in the Confucian tradition, ritual practice and cosmology ofli, which suffered major decline in the twentieth century with modern China’s political upheaval and social shifts. In recent decades, scholars and practitioners in China have sought to revive the lost art of the Archery Rites. The most significant endeavor to date is the “Re-Making of Confucian Rites (RCR),” a major reenactment project based on the renewed philological study of theBook of Etiquette and Rites(Yili), which describes rituals recorded by disciples of Confucius in fifth century BCE. The RCR project is forging the fundamental means to reconstruct and build new archives for the embodied knowledge systems of Confucian rites, through the coupling of reenactment with advanced digital documentation forms, in conjunction with novel interactive and immersive media art experiences for their affective transmission. The approaches arising from this work are building a foundation for the renewed scholarship and societal practice of the Archery Rites, as well as a cohesive framework to address the challenges facing the wider revival of intangible cultural heritage in China today.
On a Recent Conjecture by Z. Van Herstraeten and N. J. Cerf for the Quantum Wigner Entropy
Authors: Dias Nuno Costa , Prata João Nuno 
Published: April 2023

AbstractWe address a recent conjecture stated by Z. Van Herstraeten and N. J. Cerf. They claim that the Shannon entropy for positive Wigner functions is bounded below by a positive constant, which can be attained only by Gaussian pure states. We introduce an alternative definition of entropy for all absolutely integrable Wigner functions, which is the Shannon entropy for positive Wigner functions. Moreover, we are able to prove, in arbitrary dimension, that this entropy is indeed bounded below by a positive constant, which is not very distant from the constant suggested by Van Herstraeten and Cerf. We also prove an analogous result for another conjecture stated by the same authors for the Rényi entropy of positive Wigner functions. As a by-product we prove a new inequality for the radar-ambiguity function (and for the Wigner distribution) which is reminiscent of Lieb’s inequalities.
