Shifting responsibility and denying justice: New Zealand’s contentious approach to Pacific climate mobilities
Authors: Neef Andreas , Benge Lucy 
Published: July 2022

Abstract
It is increasingly evident that climate change is intersecting in complex ways with the more traditional drivers of migration, such as poverty and conflict. Yet there remains a startling lack of international agreement on how to address the issue. This article examines the problem climate change-related migration poses in terms of international responsibility and provides a review of two approaches to addressing this challenge. First, the idea that migration in the context of climate change requires the development of a new international protection agreement and, second, the argument that migration should be managed and mitigated through in situ adaptation and development programmes. These approaches differ in terms of how they understand the relationship between migration and climate change and thus differ also in terms of how they situate responsibility and address issues of climate justice. This paper explores these differences and outlines the benefits and challenges of both. Following this, we turn to the case of New Zealand’s immigration tribunal appeals involving claims for climate-refugee status and look at how in situ adaptation, development narratives and arbitrary risk thresholds have been used to legitimise the denial of these claims. Throughout the article, we ask to what extent these approaches acknowledge climate justice, and we conclude by looking at ways that climate (mobility) justice might be better incorporated into solutions that prioritise the needs of migrants in the context of rapid climate change.
Uniqueness of Local, Analytic Solutions to Singular ODEs
Authors: de Jong Thomas Geert , van Meurs Patrick 
Published: July 2022

AbstractWe study local, analytic solutions for a class of initial value problems for singular ODEs. We prove existence and uniqueness of such solutions under a certain non-resonance condition. Our proof translates the singular initial value problem to an equilibrium problem of a regular ODE. Then, we apply classical invariant manifold theory. We demonstrate that the class of ODEs under consideration captures models which describe the shape of axially symmetric surfaces which are closed on one side. Our main result guarantees smoothness at the tip of the surface.

Published: July 2022

AbstractHIV is a manageable chronic illness, due to advances in biomedical management. However, many people living with HIV (PLHIV) continue to experience psychosocial challenges, which have been associated with poorer quality of life (QoL). This study aimed to explore how psychosocial factors contributed to the QoL of PLHIV in Australia; specifically, the relationship between HIV-related stigma, social connectedness, mental health, and QoL. Participants were 122 PLHIV attending The Albion Centre (a tertiary HIV clinic in Sydney, Australia), who completed questionnaires which measured HIV-related stigma, social support, mental health symptomology and QoL. Results indicated that HIV-related stigma predicted poorer QoL, as did mental health symptomology. Conversely, social connectedness improved QoL. Additionally, social connectedness was found to mediate the relationship between HIV-related stigma and QoL, whereas the hypothesized moderating role of mental health symptomology on this model was not significant. These findings provide insight into the impact of psychosocial factors on QoL, offering practitioners various points of clinical intervention.

Abstract
The impact of exercise training and physiotherapy on heart function and pulmonary circulation parameters in heart failure with preserved ejection fraction (HFpEF) patients is uncertain. Hence, we performed a systematic review of published trials studying physical training in HFpEF population, with a focus on exercise and physiotherapy effect on left ventricular (LV), right ventricular (RV) morphological, functional, and pulmonary circulation parameters. We searched Cochrane Library and MEDLINE/PubMed for trials that evaluated the effect of exercise training and/or physiotherapy in adult HFpEF patients (defined as LVEF ≥ 45%), including publications until March 2021. Our systematic review identified eighteen articles (n = 418 trained subjects, 4 to 52 weeks of training) and covered heterogeneous trials with various populations, designs, methodologies, and interventions. Five of twelve trials revealed a significant reduction of mitral E/e’ ratio after the training (− 1.2 to − 4.9). Seven studies examined left atrial volume index; three of them showed its decrease (− 3.7 to − 8 ml/m2). Findings were inconsistent regarding improvement of cardiac output, E/A ratio, and E wave DecT and uncertain for RV function and pulmonary hypertension parameters. For now, no reliable evidence about rehabilitation effect on HFpEF cardiac mechanisms is available. There are some hypotheses generating findings on potential positive effects to parameters of LV filling pressure (E/e’), left atrium size, cardiac output, and RV function. This encourages a broader and more complex assessment of parameters reflecting cardiac function in future HFpEF exercise training studies.
Rethinking polycentricity: on the North–South imbalances in transnational climate change governance
Authors: Kaiser Cille 
Published: July 2022

AbstractThe transnational climate change governance (TCCG) landscape, led by sub- and non-state actors including businesses, municipalities, and NGOs, holds legitimate potential for tackling persisting climate injustices, in part by virtue of its polycentric character. However, while in theory polycentric governance systems could serve to correct structural power imbalances, the geography of TCCG remains remarkably uneven. This article explores this puzzle in the context of polycentric governance theory and the allegedly paradoxical relationship between polycentricity and equity. Two interrelated empirical and analytical research questions are addressed: (1) How is TCCG organized geographically along the global North–South divide? And, based on the geography of TCCG, (2) Does its polycentric character contribute toward more equitable governance across the global North and South? Following a large-Nanalysis of a novel dataset containing 174 governance arrangements and 1196 stakeholders with decision-making powers, I argue that the geography of TCCG is remarkably resistant to change, gravitating unmistakably toward the global North and its existing diplomatic hotspots. I argue that the TCCG system currently in place resembles a system of concentrated polycentricity—a product of an overarching system of rules shared with the international regime that could, in turn, potentially explain the persisting North–South inequities in a still seemingly increasingly polycentric climate.
Enhanced bit error rate in visible light communication: a new LED hexagonal array distribution

Published: July 2022

AbstractDue to the exponential growth of mobile devices and wireless services, a huge demand for radio frequency has increased. The presence of several frequencies causes interference between cells, which must be minimized to get the lower bit error rate (BER). For this reason, it is of great interest to use visible light communication (VLC). This paper suggests a VLC system that decreases the BER with applying a new LED distribution with a hexagonal shape using different techniques: on–off keying (OOK), quadrature amplitude modulation, and frequency reuse concept to mitigate the interference between the reused frequencies inside the hexagonal shape. The BER is measured in two scenarios line of sight (LoS) and non-line of sight for each technique that we used. The recommended values of BER in the proposed model for soft frequency reuse in case of LoS at 4, 8, and 10 dB signal to noise ratio, are 3.6 × 10–6, 6.03 × 10–13, and 2.66 × 10–18, respectively.
The epistemic normativity of conjecture
Authors: Simion Mona 
Published: July 2022

AbstractThis paper has two aims: (1) it develops and defends a fully-fledged account of the epistemic normativity of conjecture (2) it goes sharply against orthodoxy, in arguing that conjecture is epistemically more demanding than assertion. According to the view defended here, one’s conjecture thatpis permissible only if one knows that one has warrant, but not sufficient warrant to believe thatp. I argue for my account on three independent grounds: (1) the Bach and Harnish account of the nature of communicative speech acts, (2) the plausible normative relation between assertion and other constatives, and (3) the normativity of belief in conjunction with constatives’ epistemic function.

AbstractThe Lunar Mineralogical Spectrometer (LMS) is one of the main payloads on the Chang’E-5 (CE-5) lunar probe, belonging to the China Lunar Exploration Program. The scientific objective of the LMS is to explore the mineralogical composition and search for evidence of -OH/H2O in the sampling area. The LMS consists of an optomechanism unit, a dustproof calibration unit (DPCU) and an electronic unit. The LMS is installed on the lander about 1.4-m above the lunar surface, the field of view (FOV) is $4.17\times 4.17^{\circ }$

Priority Water Rights for Irrigation at the River Basin Level. Do They Improve Economic Efficiency During Drought Periods?
Authors: Gutiérrez-Martín Carlos , Gómez-Limón José A. , Montilla-López Nazaret M. 
Published: July 2022

AbstractThis paper assesses the potential efficiency gains of reforming the water rights regime in the Spanish agricultural sector by replacing current allocation procedures based on the proportional rule with a priority allocation procedure based on two tiers of security-differentiated water rights. This assessment is useful for evaluating whether said change in water rights can be considered a suitable policy instrument to improve water management during droughts events. For this purpose, a mathematical programming model is built to simulate the performance of the proposed reform. The empirical analysis is implemented at the basin scale, where water rights holders are highly heterogeneous, considering different climate scenarios accounting for changes in water supply reliability. The Guadalquivir River Basin (GRB) in southern Spain is used as a case study. The results obtained show that this change in the water allocation regime would yield only modest economic efficiency gains under the current climate scenario. However, it is also evidenced that this policy instrument could play a more relevant role as an efficiency enhancer in a climate change scenario, given that more frequent and intense drought episodes are expected. Moreover, priority rights represent an interesting risk management instrument for farmers, allowing the most vulnerable farmers to reduce income volatility. These findings suggest that the combined implementation of the proposed shift in the allocation regime with spot or allocation water markets would lead to successful outcomes, significantly improving drought management in the irrigation sector.
Training surgical skills on hip arthroscopy by simulation: a survey on surgeon’s perspectives

Published: July 2022

Abstract
Purpose
The purpose of this study is to investigate the importance of general and specific surgical skills for hip arthroscopy from the perspective of surgeons in China. Concurrently, we intend to identify the preferred type of simulation that would facilitate competency of surgical trainees in performing arthroscopy and reinforce their preparation for carrying out the actual surgical procedure.

Methods
An online survey comprising 42 questions was developed by experts in hip arthroscopy and sent to 3 online communities whose members are arthroscopic surgeons in China. The responses collected were based on a 5-point Likert scale, with an open-ended comment section. Data were analyzed using one-way AVOVA and post hoc Tukey’s test.

Results
A total of 159 valid responses from 66 junior specialist surgeons, 68 consultant surgeons, and 25 senior consultant surgeons (from 130 institutions in 27 out of 34 provincial administrative districts in China) were collected. Cognitive ability was identified as the overall most important attribute for hip arthroscopic trainees to possess, while skills relevant to the treatment of femoroacetabular impingement (FAI) were considered as the most important specific skills by the surgeons surveyed. In addition, simulation using cadaveric specimens was considered the most favorable method for surgeons to practice their surgical skills.

Conclusion
In designing a training program for hip arthroscopy, it is essential to incorporate features that evaluate cognitive skills. It would be helpful for trainees to specifically practice skills that are often used in the treatment of some very common diseases of the hip joint, such as FAI. Using high-fidelity physical models for simulation to train skills of hip arthroscopy could be an ideal alternative and effective way to overcome problems arising from the lack of accessibility to cadaveric specimens.
Multivariate tempered stable additive subordination for financial models
Authors: Semeraro Patrizia 
Published: July 2022

AbstractWe study a class of multivariate tempered stable distributions and introduce the associated class of tempered stable Sato subordinators. These Sato subordinators are used to build additive inhomogeneous processes by subordination of a multiparameter Brownian motion. The resulting process is additive and time inhomogeneous and it is a generalization of multivariate Lévy processes with good fit properties on financial data. We specify the model to have unit time normal inverse Gaussian distribution and we discuss the ability of the model to fit time inhomogeneous correlations on real data.
Getting fit for the Mathematical Olympiad: positive effects on achievement and motivation?

Published: July 2022

AbstractAll around the world, there are numerous academic competitions (e.g., “Academic Olympiads”) and corresponding training courses to foster students’ competences and motivation. But do students’ competences and motivation really benefit from such courses? We developed and evaluated a course that was designed to prepare third and fourth graders to participate in the German Mathematical Olympiad. Its effectiveness was evaluated in a quasi-experimental pre- and posttest design (N = 201 students). Significant positive effects of the training were found for performance in the academic competition (for both third and fourth graders) as well as mathematical competences as measured with a curriculum-oriented test (for fourth graders only). Differential effects across grade levels (with more pronounced positive effects in fourth-grade students) were observed for students’ math self-concept and task-specific interest in mathematics, pointing to possible social comparison effects.
Compositional testing of management conformance for multi-component enterprise applications
Authors: Soldani Jacopo , Luthmann Lars , Gottwald Nicolas , Lochau Malte , Brogi Antonio 
Published: July 2022

AbstractThe management of modern enterprise applications is automated by coordinating the deployment, configuration, enactment, and termination of their components. Choosing among different candidate implementations for a specified application component requires such implementations to conform to the specified management behaviour. This holds especially if we wish to ensure that the overall application management can continue as planned, or that no additional (potentially undesired) management activity gets enabled. To this end, we introduce a formal framework for testing “management conformance”, i.e., to test whether a candidate implementation can be managed according to the management protocol specifying the allowed management for a component. We also illustrate how our framework enables to run four different conformance tests, each providing a different trade-off between implementation freedom and guarantees on the overall application management. We formally prove that testing management conformance with constraints reducing implementation freedom results in preserving all already allowed management activities when implementing a specification by choosing a conforming implementation and that no additional (potentially undesired) management activity gets enabled. Finally, we assess our framework by means of a prototype implementation and its use in an experimental evaluation.

Abstract
Purpose of Review
This review aims to emphasize interesting and important new findings with a focus on the spectrum of spondyloarthritis (SpA) in China.

Recent Findings
Over the past decade, significant advances have been made in the investigation of SpA epidemiology, the exploration of genetic and environmental risk factors, the identification of clinical features, and the updating of treatment protocols in the Chinese population. The prevalence of ankylosing spondylitis (AS) in China is 0.20–0.42%, and the prevalence of HLA-B27 in AS patients is 88.8–89.4%. HLA-B*2704 is the most common subtype in Chinese AS patients, followed by HLA-B*2705. HLA-A*01, more precisely HLA-A*01:01, may be associated with psoriatic arthritis (PsA). Tumor necrosis factor inhibitors and IL-17A inhibitors have been shown to be effective and safe for AS patients in China. Juvenile-onset AS is relatively rare, accounting for only 9.1% of the AS population. The prevalence of arthritis related to inflammatory bowel disease is 6.9 to 7.2%. A Chinese study showed that the most frequently prescribed medication was methotrexate (66.4%). Biological agents were prescribed in only16.4% of patients with PsA.

Summary
This review summarizes the latest research in the epidemiology, pathogenesis, clinical manifestations, and management of SpA among Chinese populations. Multiple HLA associations with SpA have also been described, and it is hoped that discoveries of such ethnic-specific risk factor(s) and understanding of their pathological mechanisms may potentially lead to newer targeted therapies for the Chinese populations worldwide.
RETRACTED ARTICLE: Financial risk assessment to improve the accuracy of financial prediction in the internet financial industry using data analytics models
Authors: Du Guansan , Elston Frank 
Published: July 2022

AbstractA sound credit assessment mechanism has been explored for many years and is the key to internet finance development, and scholars divide credit assessment mechanisms into linear assessment and nonlinear assessment. The purpose is to explore the role of two important data analytics models including machine learning and deep learning in internet credit risk assessment and improve the accuracy of financial prediction. First, the problems in the current internet financial risk assessment are understood, and data of MSE (Micro small Enterprises) are chosen for analysis. Then, a feature extraction method based on machine learning is proposed to solve data redundancy and interference in enterprise credit risk assessment. Finally, to solve the data imbalance problem in the credit risk assessment system, a credit risk assessment system based on the deep learning DL algorithm is introduced, and the proposed credit risk assessment system is verified through a fusion algorithm in different models with specific enterprise data. The results show that the credit risk assessment model based on the machine learning algorithm optimizes the standard algorithm through the global optimal solution. The credit risk assessment model based on deep learning can effectively solve imbalanced data. The algorithm generalization is improved through layer-by-layer learning. Comparison analysis shows that the accuracy of the proposed fusion algorithm is 25% higher than that of the latest CNN (Convolutional Neural Network) algorithm. The results can provide a new research idea for the assessment of internet financial risk, which has important reference value for preventing financial systemic risk.
The impact of non-harmonious goals on partner support and taking on opportunities

Published: July 2022

AbstractRomantic partners often support each other to progress toward goals. However, at times partners’ goals are not in harmony and conflict with partner or relationship needs, leading to negative consequences for couple members. The present study examined whether non-harmonious opportunities were associated with support provider’s and recipient’s behavior, perceived partner support, and goal outcomes. We further examined whether these effects were moderated by attachment styles. Findings from two experimental (n1= 296, n2= 117) and one dyadic daily diary (n3= 267) showed how having non-harmonious goals lead to problematic goal pursuit. Partners are less likely to behave positively toward the support provider, provide partner support, view their partners as supportive, and report less commitment to partners, and make less goal progress when goal non-harmony is present. Importantly, we did not find moderation effects of attachment styles for these processes. The findings highlight the importance of managing goal non-harmony in couples.
