Point particle E-models

We show that the same algebraic data that permit to construct the Lax pair and the r-matrix of an integrable non-linear σ-model in 1 + 1 dimensions can be also used for the construction of Lax pairs and of r-matrices of several other non-trivial integrable theories in 1 + 0 dimension. We call those new integrable theories the point particle E-models, we describe their structure and give their physical interpretation. We work out in detail the point particle E-modelsassociated to the bi-Yang–Baxter deformation of the SU(N) principal chiral model. In particular, for each complex flag manifold we thus obtain a two-parameter family of integrable models living on it.

Conceptualizing parenthood: American newspaper discourse analysis

This study aims to elucidate the metaphorical representations of the concept PARENT within American media discourse. By analyzing the conceptual metaphors employed in newspaper discourse, we seek to reconstruct the metaphorically derived understanding of parenthood within English-speaking community. These conceptual metaphors, crafted by media presenters, exert a profound influence on the societal comprehension of this concept, both directly and indirectly. The study draws upon the Conceptual Metaphor theory, Conceptual Integration theory, and Discourse analysis. Within the scope of our investigation, the target domain PARENT encompasses four primary source domains: DUTIES, DIFFICULTIES, OWNER, and BURDEN. Our emphasis lies in scrutinizing the cross-domain mappings, which delineate systematic correspondences between the target and source domains. We investigate novel conceptualizations that emerge from conventional metaphoric patterns, employing cognitive mechanisms such as extension, elaboration, questioning, and combination. We also explore the conceptual blends and emergent structures that introduce additional layers of interpretation of being a parent. They are elucidated using Conceptual Integration Networks, specifically double- and multiple-scope models. Our analysis has unveiled the existence of four metaphorical clusters, each providing unique perspectives on how parenthood is conceptualized within the newspaper discourse.

Developments in event conceptualisation and event integration in language and mind

Abstract This essay is the introduction to the Special Issue ‘Events in language and mind: Theoretical and empirical advances in the event integration theory’. We first review Leonard Talmy’s event integration theory in addition to some critiques of this framework. Following this, we point to some empirical research inspired by this framework, which explores the interaction between language and cognition. We then briefly introduce the papers in this volume and discuss their contributions to the event integration framework. We conclude with some limitations, questions and future directions.

Higher Time-Derivative Theories from Space–Time Interchanged Integrable Field Theories

We compare a relativistic and a nonrelativistic version of Ostrogradsky’s method for higher-time derivative theories extended to scalar field theories and consider as an alternative a multi-field variant. We apply the schemes to space–time rotated modified Korteweg–de Vries systems and, exploiting their integrability, to Hamiltonian systems built from space–time rotated inverse Legendre transformed higher-order charges of these systems. We derive the equal-time Poisson bracket structures of these theories, establish the integrability of the latter theories by means of the Painlevé test and construct exact analytical period benign solutions in terms of Jacobi elliptic functions to the classical equations of motion. The classical energies of these partially complex solutions are real when they respect a certain modified CPT-symmetry and complex when this symmetry is broken. The higher-order Cauchy and initial-boundary value problem are addressed analytically and numerically. Finally, we provide the explicit quantization of the simplest mKdV system, exhibiting the usual conundrum of having the choice between having to deal with either a theory that includes non-normalizable states or spectra that are unbounded from below. In our non-Hermitian system, the choice is dictated by the correct sign in the decay width.

Differences in audiovisual temporal processing in autistic adults are specific to simultaneity judgments.

Research has shown that children on the autism spectrum and adults with high levels of autistic traits are less sensitive to audiovisual asynchrony compared to their neurotypical peers. However, this evidence has been limited to simultaneity judgments (SJ) which require participants to consider the timing of two cues together. Given evidence of partly divergent perceptual and neural mechanisms involved in making temporal order judgments (TOJ) and SJ, and given that SJ require a more global type of processing which may be impaired in autistic individuals, here we ask whether the observed differences in audiovisual temporal processing are task and stimulus specific. We examined the ability to detect audiovisual asynchrony in a group of 26 autistic adult males and a group of age and IQ-matched neurotypical males. Participants were presented with beep-flash, point-light drumming, and face-voice displays with varying degrees of asynchrony and asked to make SJ and TOJ. The results indicated that autistic participants were less able to detect audiovisual asynchrony compared to the control group, but this effect was specific to SJ and more complex social stimuli (e.g., face-voice) with stronger semantic correspondence between the cues, requiring a more global type of processing. This indicates that audiovisual temporal processing is not generally different in autistic individuals and that a similar level of performance could be achieved by using a more local type of processing, thus informing multisensory integration theory as well as multisensory training aimed to aid perceptual abilities in this population.

On torsion of FG elastic nanobeams on nonlocal foundations

A plethora of challenging nanomechanical applications deals with ultrasmall composite structures interacting with nonlocal media. To capture size dependent behaviors, effective tools of Nonlocal Continuum Mechanics can be conveniently adopted, provided that the relevant structural problem is well-posed. A crucial improvement in modeling of nanobeams on nanofoundations is provided in the present work with respect to the formulation based on the Eringen–Wieghardt nonlocal approach. Scale effects on FG nanobeams under torsion are effectively captured by exploiting the consistent stress-driven integral theory of elasticity. A novel formulation of size dependent elastic foundations is here introduced. Notably, the constitutive behavior describing interaction between twisted nanobeams and surrounding media is modeled by spatial convolution driven by the torsional rotation field. It is shown that the governing structural problem is mathematically represented by an integro-differential formulation. An equivalent simpler differential problem is then proven to reduce computational burdens. Exemplar case-studies are finally examined to show efficacy of the developed nonlocal methodology.

Principles of surgery according to the Integral Theory Paradigm (ITP).

A core concept of the Integral Theory System is that "ligaments are for structure; vagina is for function". The vagina and uterus should be conserved. Because the vagina is an organ, its collagen and elastin, which are so necessary for its function, cannot regenerate once they are removed. Removing the uterus involves severing the descending uterine artery, which is the principal blood supply of the proximal part of the uterosacral ligaments (USLs), and so may cause atrophy, which can cause future incontinence problems because of collagen loss after menopause. The diagnostic algorithm guides which of the five pelvic ligaments need repair. Native ligament plication can be adequate for prolapse/symptom cure, but only in premenopausal women. Postmenopausal women are usually collagen deficient and require collagen-creating tapes or wide-bore polyester sutures to restore structural collagen in the ligaments. Of extreme importance, vaginal tissue excision should be avoided, as consequent scarring may cause "tethered vagina syndrome" (TVS). TVS can cause massive uncontrolled urine loss because the scar tissue in the bladder neck area of the vagina can link the more powerful posterior muscles to the anterior, so the posterior urethra wall is forcibly pulled open, when given the signal to close. Instead of vaginal excision, a "concertina" suture technique re-assigns and shrinks excess vaginal tissue to normal anatomy by 6 weeks. In conclusion, the five key surgical principles of the Integral Theory System are: ligaments are for structure, vagina is for function; structure (prolapse) and function (symptoms) are related; repair the structure and you will restore the function; avoid vaginal excision and hysterectomy; create new collagen to reinforce the damaged ligaments.

Facebook usage by students in higher education

In this paper I measure first year student Facebook usage as part of a broader PhD study into the influence of social media usage on the success of students in higher education. A total of 906 students were asked to complete 3 surveys on Facebook usage with their peers, for two consecutive years (2011-2012 and 2012-2013). The different purposes for Facebook usage, in addition to whether or not students used (self-created) Facebook-groups, were measured and the relationship between the use of pages compared to the purpose of Facebook usage. This resulted in significant correlations between the purpose of Facebook usage and the use of different pages, as well as correlations between the purpose and use of different pages. This study hereby explores the variation in student Facebook usage and provides valuable insight into the potential value of Facebook for students in an educational setting, without the interference of teachers. It is also the next logical step in revising existing integration and engagement theories that predict student success in higher education in contemporary society.

A brief physiology and pathophysiology of the anorectum based on the Integral Theory paradigm.

The remit of this review is confined to the experimental scientific works and surgeries based on the Integral Theory paradigm. The video abstract summarizes the anorectal function, how ligaments cause dysfunction and cure of fecal incontinence and obstructed defecation by ligament repair. Anorectal function is reflex and binary, with cortical and peripheral components. The same three oppositely acting reflex muscle forces which open and close the bladder, contract against the pubourethral (PUL) and uterosacral (USL) ligaments: (I) to close the anorectum for continence when the puborectalis muscle (PRM) contracts forwards; (II) to open the anorectum prior to evacuation when the PRM relaxes; (III) to stretch the rectum in opposite directions to support the anorectal stretch receptors "N" to prevent premature activation of the defecation reflex, (fecal urgency). Weak or loose PULs or USLs may cause dysfunction of closure, of evacuation, and inability to control the defecation reflex (fecal urgency). Repair of the PUL and USL can improve or cure these dysfunctions. The perineal body (PB) acts as an anatomical support for the distal vagina, anorectum and external anal sphincter (EAS). It serves as an anchoring point for the forward action of the pubococcygeus muscle (PCM), which tensions the anterior rectal wall during closure and defecation. Bladder and bowel dysfunction have a similar pathogenesis, ligament laxity, mainly pubourethral and uterosacral, with added PB damage for anorectal dysfunction. PB damage can cause obstructive defecation and descending perineal syndrome (DPS). Repair of damaged PUL and USL can restore the closure and evacuation functions of both bladder an anorectum. DPS can be cured by repair of the PB's suspensory ligaments, deep transversus perinei.

Wide-bore polyester sutures may create sufficient collagen for cure of prolapse/incontinence: a work in progress.

The main thrust of the Integral Theory Paradigm (ITP) is that inadequate ligament collagen causes pelvic organ prolapses (POP) and pelvic symptoms, a concept validated by multiple publications which cured POP and bladder/bowel/pain dysfunctions by collagen-creating slings. Sling surgery for surgical cure of these conditions was eliminated in the United States, Europe and other regulatory jurisdictions by banning all mesh products (including tapes) in about 2017. The aim of this work was to inform of the progress of a highly promising alternative method for collage creation for ligament repair: wide-bore polyester sutures accurately applied to weak ligaments. The scientific rationale for the wide-bore polyester plication method was a revisit and analysis of prior Instron testing data from a rejected polyester aortic graft from a doctoral thesis. The analysis indicated that the collagen produced by No. 2 polyester sutures would be sufficient to repair weakened pelvic ligaments. The surgical methodology consisted of application of wide-bore No. 2 or No. 3 polyester sutures to existing vaginal surgical techniques such as cardinal/uterosacral ligament (CL/USL) repair in the Fothergill operation, deep transversus perinei (DTP) ligamentous supports of the perineal body (PB) and uniquely, pubourethral ligament (PUL) repair for stress urinary incontinence (SUI). No vaginal tissue was excised. These operations are now being performed in several centres around the world. Because of this, the results detailed below are indicative only, and necessarily incomplete, as they are only from these units. Twelve month data (n=35) for SUI cure (83%) following PUL repair by the urethral ligament plication (ULP) operation has been submitted for publication; POP quantification (POPQ) points Ba, C, Bp, D were significantly improved at 6 weeks postoperative review following repair of CLs (cystocele) and USLs (uterine/apical prolapse) (n=56): deep transverse perinei ligament repair (descending perineal syndrome "DPS") (n=4) were cured at 6-12 months review. Though numbers are few, in the context of DPS being considered incurable, these numbers are significant. Except for the ULP operation, the techniques for cystocele, uterine prolapse, perineocele were essentially evolved versions of the Fothergill and standard PB repairs without any vaginal or ligament excisions. Though promising, more extensive and longer-term results are clearly required before this wide-bore polyester ligament repair method can become mainstream.

Calculation method and analysis of residual stress in the strip bending roller straightening process

Taking thin gauge strip as an example, the deformation process of metal strip in bending roll straightening was studied. Based on the theory of discrete, curvature integral and elastic–plastic mechanics, the strip travel trajectory of the bending roll straightening process is analyzed, and the numerical analytical calculation method of the continuous straightening process of the strip bending roll is established. The results are verified by establishing MARC finite element simulation and designing straightening experiment. The effects of yield strength, plastic rate and bending amount on residual stress after straightening were studied. In the straightening process, with the increase of the amount of bending roll, the residual strain converges to the region Γ, and with the increase of the yield strength, the region Γ decreases. With the increase of the yield strength, the amount of bending roll and the plastic rate, the wave height increases. The results of the calculation of residual stress, finite element simulation and experiment are close and the trend is consistent. The results show that the logic of the calculation method is reasonable, and the prediction error is within the scope of engineering application, which is helpful to the realization of process intelligence in the process of bending roller straightening.

A Roadmap for Applying the Contextual Integrity Framework in Qualitative Privacy Research

Privacy is an important topic in HCI and social computing research, and the theory of contextual integrity (CI) is increasingly used to understand how sociotechnical systems-and the new kinds of information flows they introduce-can violate privacy. In empirical research, CI can serve as a conceptual framework for explaining the contextual nature of privacy as well as an analytical framework for evaluating privacy attitudes and behaviors. Analytical applications of CI in HCI primarily employ quantitative methods to identify appropriate information flows but rarely engage with the full CI framework to evaluate such flows. In this paper, we present a roadmap to guide HCI and social computing researchers on how to apply the full CI framework to qualitative projects. To help researchers envision what such an analysis can look like, each step includes an example analysis using interview data from projects on privacy and fitness tracking. We conclude by discussing how harnessing the full CI framework can address critiques of CI and identify opportunities for further theory development.

Should sacrouterine plication be added to lateral suspension surgery? A prospective study.

Laparoscopic lateral suspension is a novel approach for repairing anterior and apical pelvic organ prolapse (POP). According to integral theory, urinary symptoms and pelvic pain are believed to originate from suspensory ligaments. We aimed to investigate the objective and subjective outcomes of adding sacroterine plication to apical prolapse surgery. Sixty patients with Grade 2 or higher symptomatic apical POP were included in the study. The study sample was categorized into two groups: Group 1 underwent lateral suspension and Group 2 underwent lateral suspension and sacroterine plication. Anatomical cure was defined separately for the apical and anterior compartments as POP-Q scores for sites C and Ba of less than -1 cm for each compartment. A subjective cure was defined as the absence of bulge symptoms. Patient satisfaction, sexual function, prolapse-related quality of life, voiding dysfunction, nocturia, and constipation were assessed. In Group 1, anatomical cure rates for apical and anterior prolapse were 100% and 70%, respectively (p <0.001). In Group 2, these rates were 100% for apical prolapse and 73.3% for anterior prolapse (p <0.001). The subjective cure was 96.6% in both groups. Furthermore, improvement in sexual and urinary symptoms was more significant in the group that underwent sacroterine plication (p <0.001). The additional sacroterine plication (shortening) procedure with lateral suspension proved to be an effective and successful surgical approach for apical prolapse. Its routine addition to existing lateral suspension surgery can contribute significantly to the improvement of urinary and prolapse symptoms.

Investigating factors influencing the intention to revisit Mount Semeru during post 2022 volcanic eruption: Integration theory of planned behavior and destination image theory

Mount Semeru is one of the most popular tourist destinations in East Java, Indonesia. However, its 2022 volcanic eruption has caused devastating impacts on the surrounding area, particularly on its tourism; considering that the livelihood of nearby communities heavily relies on its tourism. Nonetheless, the lack of studies on the revisit intention of tourists after the post-recovery period of Mount Semeru urged the researchers to address this issue. The objective of this study is to investigate the factors that influence the intention of tourists to revisit Mount Semeru during post 2022 volcanic eruption by utilizing an integrated extended Theory of Planned Behavior (TPB) and Destination Image. A total of 326 Indonesian mountaineers voluntarily answered a self-administered online survey that was distributed by utilizing a purposive sampling method. Structural Equation Modeling (PLS-SEM) revealed that past disaster experiences had significant effects on perceived behavioral control, destination image, and perceived value which subsequently led to subjective norm and revisit intention. In addition, Government support also had a significant effect on perceived value which also subsequently led to subjective norm and revisit intention. Interestingly, media had a significant direct effect on revisit intention. This study is one of the first studies to highlight the 2022 Mount Semeru volcanic eruption. Moreover, the findings of this study could be used to develop effective promotional strategies and track tourist behavior during their subsequent visits to Mount Semeru. Furthermore, the theoretical framework of this study could be extended and applied to various destinations during post disaster period.

Could marriage be a glorified transactional relationship? A cognitive blending approach to analogies of marriage in Dholuo

The last few decades have seen declining marriage rates as people prioritize other life goals over marital commitments. While the explanations for this shifting tide are multifaceted, scholarly evidence suggests that portrayal of marriage in a negative light scares many young adults from the institution. Every community equips its people with experiences, attitudes and linguistic resources to conceptualize abstract phenomena such as marriage. Against this background, this study seeks to analyze analogies of marriage in Dholuo to reveal how cultural resources and experiences influence the conceptualization of marriage. The study adopts a descriptive research design. Data for the study was collected through interviews. Forty (40) speakers of the Kisumu South Nyanza (KSN) dialect were asked to provide analogies used to describe marriage in Dholuo. A total of 66 analogies were collected. Four annotators used the synectic method of analogy identification to verify the collected expressions. One analogy which implies that marriage is a transactional relationship was selected for analysis using the Conceptual Integration Theory (CIT). The study found that analogies pervade daily conversations but they are unconsciously used to describe abstract phenomena such as marriage. Additionally, the study found that in some marriages in the Luo community, love chemistry, compatibility and emotional investment take a backseat and partners see each other as a means to satisfy their selfish interests. The findings also indicate that conceptual mental spaces as a tenet of the CIT provide a plausible model for interpreting marriage as an abstract concept in Dholuo. The study concludes that analogy is culture-specific and should be investigated through the lenses of a cognitive linguist.

Fubini’s theorem for Daniell integrals

We show that in the theory of Daniell integration iterated integrals may always be formed, and the order of integration may always be interchanged. By this means, we discuss product integrals and show that the related Fubini theorem holds in full generality. The results build on a density theorem on Riesz tensor products due to Fremlin, and on the Fubini–Stone theorem.

A multimesh finite element method for integral nonlocal elasticity using mesh-decoupling technique

This study presents a generalized multimesh nonlocal finite element method (M2-FEM) that addresses several long-standing challenges in the numerical simulation of Eringen’s integral elasticity theories, often used to model nonlocal effects. The major challenges in the numerical simulation of integral boundary value problems are primarily rooted in the coupling of the spatial discretization of the global (parent) and integral (child) domains, which severely restricts both the applicability and the computational efficiency of existing algorithms by imposing an implicit trade-off between the accuracy of the child domain and the resources required by the overall parent domain. One of the defining contributions of this study consists in the development of a mesh-decoupling technique that generates isolated sets of meshes such that the parent and child domains can be discretized and approximated independently. This mesh-decoupling has multi-fold advantages on the simulation of integral theories such that, when compared to existing state-of-the-art techniques, the proposed algorithm achieves a greater ability to adopt generalized integral kernel functions, the ability to handle non-regular (non-rectangular) domains via unstructured meshing, and simultaneously better numerical accuracy and efficiency (hence allowing greater flexibility in both mesh size and computational cost trade-off decisions). Both benchmark studies and several case studies are conducted to assess the effectiveness of M2-FEM. Simulation results confirm that M2-FEM can accurately simulate integral nonlocal problems and demonstrate its multi-fold computational advantages over existing mesh-coupling-based nonlocal finite element methods. Overall, the proposed M2-FEM algorithm is very general and it can be applied to a variety of integral theories, even beyond nonlocal elasticity.
