TRAPPING PROBLEM OF HONEYPOTS ON FRACTAL NETWORKS WITH THE STURMIAN STRUCTURE
Authors: HUANG YUKE , ZENG CHENG , XUE YUMEI
Published: August 2023

This paper studies the average trapping time of honeypots on some evolving networks. We propose a simple algorithmic framework for generating networks with Sturmian structure. From the balance property and the recurrence property of Sturmian words, we estimate the average trapping time of our proposed networks with an asymptotic expression [Formula: see text], where [Formula: see text] is a bounded expression related to word [Formula: see text]. We next consider networks with multi-honeypots and generalize our basic models. Additionally, we give an symmetrical method to create a series of networks with the Sturmian structure, and the average trapping time satisfies [Formula: see text], which is independent of any word [Formula: see text]. The generalized methods may have some illuminating effects on the study of networks with randomness.
BIFURCATION AND EXACT SOLUTIONS OF SPACE-TIME FRACTIONAL SIMPLIFIED MODIFIED CAMASSA–HOLM EQUATION
Authors: MA YANZHI , WANG ZENGGUI
Published: August 2023

In this paper, exact traveling wave solutions of space-time fractional simplified modified Camassa–Holm (mCH) equation are investigated by the bifurcation theory. The phase portraits of the equation are obtained with different parameter conditions. By analyzing different orbits, periodic wave, kink, anti-kink, burst wave, bright and dark solitary solutions of the equation are acquired. Finally, numerical simulation and the effects of fractional order taking on the dynamic behaviors of various forms of solutions are analytically discussed.
Wong–Zakai approximations for quasilinear systems of Itô's-type stochastic differential equations driven by fBm with H > 1 2
Authors: Scorolli Ramiro
Published: August 2023

In a recent paper, Lanconelli and Scorolli 10 extended to the multidimensional case a Wong–Zakai-type approximation for Itô stochastic differential equations (SDEs) proposed by Øksendal and Hu 7 . The aim of this paper is to extend the latter result to system of SDEs of Itô type driven by fractional Brownian motion (fBm) like those considered by Hu 6 . This extension is not trivial since the covariance structure of the fBm precludes us from using the same approach as that used by Lanconelli and Scorolli. Instead we employ a truncated Cameron–Martin expansion as the approximation for the fBm. We are naturally led to the investigation of a semilinear hyperbolic system of evolution equations in several space variables that we utilize for constructing a solution of the Wong–Zakai approximated systems. We show that the law of each element of the approximating sequence solves in the sense of distribution a Fokker–Planck equation and that the sequence converges to the solution of the Itô equation, as the number of terms in the expansion goes to infinite.
A Steklov version of the torsional rigidity
Authors: Brasco L. , González M. , Ispizua M.
Published: August 2023

Motivated by the connection between the first eigenvalue of the Dirichlet–Laplacian and the torsional rigidity, the aim of this paper is to find a physically coherent and mathematically interesting new concept for boundary torsional rigidity, closely related to the Steklov eigenvalue. From a variational point of view, such a new object corresponds to the sharp constant for the trace embedding of [Formula: see text] into [Formula: see text]. We obtain various equivalent variational formulations, present some properties of the state function and obtain some sharp geometric estimates, both for planar simply connected sets and for convex sets in any dimension.
A causal characterization of Spell+(2n)
Authors: Hedicke Jakob
Published: August 2023

We show that the natural bi-invariant cone structure on the linear symplectic group [Formula: see text] is globally hyperbolic in the positively elliptic region [Formula: see text]. This answers a question by Abbondandolo, Benedetti and Polterovich and implies a formula for a bi-invariant Lorentzian distance function defined by these authors for elements in this region. Moreover we give a characterization of the positively elliptic region and of [Formula: see text] in terms of the causality of this cone structure.
Effect of Distributed Loading and Refined Modeling on Wind-Induced Stress Analysis of Long-Span Bridges
Authors: Tan Zhong-Xu , Xu You-Lin , Zhu Le-Dong , Zhu Qing
Published: August 2023

Wind-induced stress analysis is essential for evaluating the local failure and fatigue damage of long-span bridges in wind-prone regions. Nevertheless, the accuracy of stress-level analysis can be affected by the choice of wind loading and structure models. This study formulates three scenarios to calculate the wind-induced response of a long-span bridge, incorporating two types of wind load models (lumped force or distributed force) and two types of finite element (FE) models (spine-beam or substructure). Specifically, Case 1 employs the lumped force and beam model, Case 2 adopts the lumped force and substructure model, and Case 3 utilizes the distributed force and substructure model. The aerodynamic parameters for forces and POD pressure modes are obtained through wind tunnel tests. By comparing the wind-induced structural response in terms of global behavior (displacement, acceleration) and local behavior (stress), the influence of wind loading and structure models is discussed. The findings reveal that employing a simplified beam model underestimates local stress, and neglecting wind load distribution leads to further underestimation. Therefore, the refined FE model and distributed wind load models are recommended for the precise assessment of wind-induced stresses in long-span bridges.
TDACVO: EXPONENTIAL TASMANIAN DEVIL ANTI-CORONAVIRUS OPTIMIZATION-ASSISTED DEEP MODEL FOR MULTI-LEVEL BRAIN TUMOR CATEGORIZATION
Authors: JETLIN C. P. , PUSPHA ANNABEL L. SHERLY
Published: August 2023

Tumors in the brain represent a general and serious disease that leads to small life expectancy. Hence, effective diagnosis preparation is indispensable to enhance the life quality of patients. This paper utilizes MRI for diagnosing the tumor in the brain. However, the MRI thwarts manual classification and poses drawbacks regarding precise quantitative measurements. Thus, automated cataloging of brain tumors is a crucial task. The main aim of this research is to provide an optimized deep model for multi-level classification with the help of MRI. The adaptive Wiener filter and Region Of Interest (ROI) mining are used to perform denoising to make an accurate diagnosis. The first-level classification is accomplished with Shepard Convolutional Neural Network (ShCNN) and its training is done with Tasmanian Devil Anti-Coronavirus Optimization (TDACVO), which categorizes suitably. If an abnormality is found, Deep Q-Network (DQN) and Exponential Tasmanian Devil Anti-Coronavirus Optimization (ETDACVO) are used to execute the second-level classification. The proposed ETDACVO-DQN provided better competence with an utmost accuracy of 93%, precision of 91.8%, and recall of 92.7%.

Authors: Qin Daoling , Zhang Guoteng , Zhu Zhengguo , Chen Teng , Zhu Weiliang , Rong Xuewen , Xie Anhuan , Li Yibin
Published: August 2023

A new method is proposed to control bipedal robots to achieve flexible omni-directional motion and robust locomotion under complex disturbances, called the heuristics-based reinforcement learning (HBRL) framework. HBRL shows great training efficiency in simulation. Heuristic reference trajectories play a crucial role in HBRL, which guide the training process. Exploration rewards, leg-foot reset condition, and command curriculum are three significant components to optimize the training process. An estimator network is utilized to supply linear velocities and foot contact information. We train controllers on flat ground in simulation. To demonstrate robustness and versatility, the trained controllers were tested on BRAVER, a point-foot bipedal robot with three joints on each leg. The controllers enabled BRAVER to perform omni-directional locomotion with the maximum forward speed reaching 2[Formula: see text]m/s. The robot could also maintain balance under external pushing and over uneven terrains.

Authors: Brunner Timo J. J. , Rudolph Katja , Lehmann Claudia
Published: August 2023

This paper seeks to explore innovation in new work practices in the context of the current COVID-19 pandemic and identify which indicators of same lead to workplace attractiveness. From a socio-demographic perspective, service industry employees constituted the focus of this study. The study employed a two-step mixed-methods approach. First, the qualitative component deduced a data structure of innovative new work practices by conducting 21 semi-structured interviews with top- and middle-level managers. Second, hypotheses were formulated based on the qualitative data, and a quantitative survey with 155 employees was used to test the effectiveness and attractiveness of innovative new work practices using psychological empowerment as a mediator. The data structure was conceptualized according to three dimensions: (i) innovating approaches to new work, (ii) innovating leadership attitudes, and (iii) innovating organizational culture. The results of the quantitative study suggest that the innovation in leadership attitude and in organizational culture have a strong influence on psychological empowerment, thereby positively influencing workplace attractiveness. This paper contributes to a uniform understanding of innovative work practices in the context of the COVID-19 pandemic. Through empirical testing, the paper highlights specific indicators of innovation in work that lead to increased workplace attractiveness. Service organizations during such crises as pandemics can concentrate on the three dimensions and the specific indicators to implement innovative work measures while increasing workplace attractiveness for their employees.
How Does Ergo-Functional Value Resonance Enhance Intention to Use? An SDL Perspective
Authors: Rini Gilang Puspita , Ferdinand Augusty Tae
Published: August 2023

This research was conducted to fill the research gap between perceived ease of use and intention to use by exploring the Service-Dominant Logic Theory in the development of ergo-functional value resonance. The process involved surveying 352 MacBook users through Instagram. The data obtained were processed using AMOS 23 and the results showed the possibility of ergo-functional value resonance serving as a mediator between perceived ease of use and intention to use. This research contributes to the perspective of Service-Dominant Logic, which regards the product as a medium for value exchange, with the actual value being the functional aspect of the product.
Particle dynamics around the Einstein–Maxwell–Yang–Mills black hole
Authors: Wang Ruifang , Gao Fabao , Chen Huixiang
Published: August 2023

The presence of matter in general relativity can cause spacetime to curve. This paper investigates the spacetime properties of the Einstein–Maxwell–Yang–Mills (EMYM) black hole by discussing the geodesic motion of neutral and charged particles. By studying the Lagrangian of these particles, equations of motion and effective potential are obtained in the asymptotic flat and (A)dS spacetimes. Moreover, for the motion of a neutral particle, it is found that there exist stable elliptic/hyperbolic orbits and unstable orbits with different energies by discussing the effective potential and the phase-plane analysis. However, for the motion of a charged particle, there exists an equilibrium point that separates these orbits. In addition, the effects of the system parameters on the potential are analyzed, including the masses of the black hole and charged particles, charges, the cosmological constant, and the strength of the external magnetic field.
Venture Capital Exits and Investments: The Influences of Market Run-up, Market Timing, and Media Attention
Authors: Chung Y. Peter , Liu Yun , Smith Richard
Published: August 2023

In this paper, we address the question of whether venture capital (VC) firms are able to add value through exit and investment timing. Considering all venture-backed exits, we find that VCs are able to time the initial public offerings (IPOs) to occur after market run-ups. However, we find no evidence that VCs can time IPOs to precede low or negative market returns. Focusing on the biotech sector, we do find evidence of successful market timing in that IPO activity is highest following market run-ups and before periods of low market returns. Controlling for leading and lagging market returns, we find little evidence that media attention influences IPO exit timing. As to new VC investments in biotech, we find that when market returns are low (high), VCs focus their investments in the sector on earlier (later) investment rounds with longer (shorter) times to anticipated harvesting.
Insight with Crystallization, Quantum Computation, Hirshfeld, ELF/LOL and Molecular Docking of Syringic Acid Nicotinamide Cocrystal as Potent Mycobacterium Tuberculosis Inhibitor
Authors: Zochedh Azar , Shunmuganarayanan Athimoolam , Sultan Asath Bahadur
Published: August 2023

Tuberculosis (TB) is a recurring and progressive illness with a high global death rate. MycobacteriumTB drug resistance is a serious impediment to allelopathy therapy. Contemplating combinatorial drug delivery (pharmaceutical cocrystal) as anti-TB medicines targeting Mycobacterium tuberculosis’s active site can be an alternative strategy. The syringic acid nicotinamide (SYNI) cocrystal was synthesized in this work through slow evaporation technique and was examined based on quantum chemical calculations, Hirshfeld analysis, electron localization analysis and molecular docking. The intended vibrational wavenumbers were allocated a PED value and related with experimental frequencies. The UV–Visible absorption spectra of the cocrystal in the liquid phase (ethanol) were revealed as [Formula: see text]* electronic transitions. The HOMO–LUMO values, band gap, molecular electrostatic potential and Mulliken atomic charge distribution of the molecule were evaluated to estimate its stability and molecular reactivity. The molecule’s second-order perturbation energy [Formula: see text] standards were determined by means of natural bond orbital analysis, and potential reactive site was assessed using local reactivity descriptors. Hirshfeld analysis revealed that H…H (44.9%), O…H/H…O (39.3%), C…H/H…C (6.1%), N…H/H…N (5.3%) and C…C (2.4%) have the major percentage contributions from the most significant interactions. The topological features of the SYNI cocrystal were assessed through electron localization function based on color gradient. The binding ability of SYNI cocrystal with the Mycobacterium tuberculosis associated proteins was evaluated through docking and their binding scores fall between the range of −9.1 kcal/mol and −10.8 kcal/mol, which confirms the better binding ability and makes SYNI cocrystal a potent medication against TB.
Effect of Nurses’ Professionalism, Work Environment, and Communication with Health Professionals on Patient Safety Culture (AHRQ 2.0.): A Cross-Sectional Multicenter Study
Authors: Lee Won , Jang Insil
Published: August 2023

Aims. To identify nurses’ professionalism, work environment, and communication with healthcare professionals as factors influencing clinical nurses’ perception of patient safety culture. Background. Patient safety is a representative indicator of the quality of nursing care. A multidisciplinary approach, including individual and organizational components, is needed to improve patient safety culture. Methods. A cross-sectional study was conducted in January 2021 involving a total of 271 nurses in six tertiary hospitals. Data were collected from participants on nurse professionalism, work environment, communication, and patient safety culture. A multiple regression model was used to analyze variables influencing patient safety culture. Results. Factors affecting patient safety culture were nursing foundations for quality of care (β = 0.230,

p
<
0.001

), nurse manager ability, leadership, support of nurses (β = 0.294,

p
<
0.001

), and collegial nurse-physician relations (β = −0.138,

p

), and timeliness (β = 0.239,

p
<
0.001

) of communication between healthcare professionals and nurses have a significant impact on patient safety culture. All these predictors accounted for 59% (R2) of patient safety culture awareness (

p
<
0.001

). Conclusions. Enhancing patient safety culture requires a systematic and organizational approach that considers individual characteristics. Nurse managers play a crucial role in promoting patient safety by employing various communication channels and leading team education and training initiatives to foster collaboration among healthcare professionals. Implications for Nursing Management. The provision of patient safety education directly influences patient safety culture, and continuous education enables nurses to grow within the institution. To ensure effective communication in healthcare settings, nurse managers should prioritize shift communication, evaluate the accuracy of information exchange, and establish diverse communication channels, including social media platforms or business messengers, for internal hospital communication.

Published: August 2023

Seromucinous hamartoma is a rare benign glandular proliferation arising from the respiratory epithelium of the sinonasal tract and nasopharynx. It was described for the first time in 1974 by Baillie and Batsakis. Since then, few cases have been reported in the literature with most of them occurring in the posterior nasal septum. We report the case of a 52-year-old woman that presented to our department with left periorbital edema, pain, and dacryorrhea due to seromucinous hamartoma arising from the left inferior turbinate and extending through the lateral nasal wall into the maxilla, the nasolacrimal duct, and the orbit. Endoscopic medial maxillectomy and endoscopic transnasal orbital tumor resection were performed. The patient remains symptom-free for 16 months, till her most recent follow-up. Seromucinous hamartoma of the nasal cavity is an exceedingly rare diagnosis, especially in the lateral nasal wall. It should be included in the differential diagnosis of nasal tumors. According to the literature review, this is the first case report of seromucinous hamartoma with orbit infiltration. Endonasal endoscopic resection is the treatment of choice.

Herbal treatment augments immune and antioxidant responses and suppresses stress in fish. Ginger (Zingiber officinale) is a popular plant with medicinal uses because of its immunostimulant, antimicrobial, and antioxidant characteristics. This study aimed to investigate the effects of ginger (Z. officinale) on growth, digestive enzymes activity, antioxidant and immune response, and salinity stress resistance of Caspian roach (Rutilus caspicus). Fish (0.98 ± 0.09 g) were divided into four treatment-fed diets containing 0 (control, Z0), 10 (Z10), 20 (Z20), and 30 (Z30) g/kg ginger powder for 56 days and then subjected to 2 g/L salinity stress for 48 hr. The highest final weight of specific growth rate (SGR), superoxide dismutase (SOD), and catalase activity and the lowest final weight of feed conversion ratio (FCR) and malondialdehyde (MDA) were observed in fish-fed diets containing 10 and 20 g/kg ginger inclusion. Intestinal protease activity significantly increased in Z10 treatment, and the highest amylase and lipase activities were related to control, including 10 g/kg ginger in the diet compared to the control group had a significant effect on immune indices such as immunoglobulin M (IgM) and ACH50 (

p
<
0.05

). The highest lysozyme was obtained in Z20 treatment, which had a significant difference in the control (

p
<
0.05

). Cortisol and glucose levels were significantly lower in ginger treatments than the control before and/or after salinity stress. Histopathologic results showed that hyperplasia, edema, expansion of secondary lamella, epithelial cells, and necrosis of gills were most common lesions. However, the results of this study demonstrate that using ginger powder in addition to improving of growth, it can be also effective in survival rate of Caspian roach fingerling as an endangered species exposed to salinity stress.

Published: August 2023

Objective. To evaluate the safety and efficacy of adrenal venous sampling (AVS) via the cubital vein and femoral vein synchronously. Methods. A total of 200 patients with primary aldosteronism admitted to the First Hospital of Fujian Medical University were enrolled and randomly divided into a single-path AVS group (SP, N = 108) and a multipath AVS group (MP, N = 92). We analyzed the clinical characteristics, intubation success rate, procedure cost, total fluoroscopy time, complications, contrast dosage, and the number of catheters selected during AVS. A planar quadrant system was established to mark the direction of the adrenal opening, with the intersection of the right renal vein and the inferior vena cava defined as the origin. In digital subtraction angiography images, the RAV opening located in the 0–3 o’clock direction was the first quadrant (I), and the 3–6 o’clock direction was the third quadrant (III). Results. There was no statistical difference between the two groups at baseline. Multipath AVS had a significantly higher success rate of right-sided intubation than single-path AVS (success rate of right-sided intubation/%: SP 87.96 vs MP 95.65,

P
=
0.043

). Total fluoroscopy time was significantly reduced (fluoroscopy time/min: SP 9.80 ± 4.07 vs MP 7.42 ± 3.48,

P
=

) and the cost of the procedure was markedly lower (cost/yuan: SP 3,900.93 ± 1,191.12 vs MP 3,378.26 ± 399.40,

P
<
0.001

). There was no significant difference in postoperative complications between the two groups. In the group I, the procedure was completed mainly with an MPA catheter (catheter selection/%: MPA 98.19 vs TIG 17.65,

P
<
0.001

). In the group III, TIG catheters were used more frequently (catheter selection/%: MPA 1.81 vs TIG 82.35,

P
<
0.001

). Conclusion. Multipath AVS via the cubital vein and femoral vein improves the success rate of AVS with comparable safety compared to single-path AVS. When the RAV is opened in the III quadrant, the TIG catheter improves the cannulation success rate. The multipath AVS method provides more catheter options. Patients diagnosed with PA at the First Hospital of Fujian Medical University from December 2019 to December 2021 were included. The collection of medical records of the included population was approved by the ethics committee (approval number: [2021] 311). This was a cross-sectional study in which some patients were treated surgically and some were treated with superselective adrenal artery embolization (SAAE). We conducted a cohort study of patients treated with SAAE. ClinicalTrials.gov Protocol Registration and Results System (PRS) receipt release date: January 11, 2022.

Published: August 2023

Intravascular large B-cell lymphoma, an extranodal large B-cell lymphoma, is a rare hematological malignancy with only a few reports of lung involvement. We report a case of intravascular large B-cell lymphoma with acute hypoxic respiratory failure and interstitial lung disease diagnosed via random skin biopsies. A 54-year-old woman presented with fever, cough, and dyspnea. Computed tomography imaging revealed findings concerning interstitial lung disease. The patient’s respiratory status worsened despite the treatment with antibiotics and steroids. Generalized edema and thrombocytopenia also developed. Intravascular large B-cell lymphoma was clinically suspected and ultimately diagnosed by skin biopsy, although she had no apparent skin lesions. The patient’s condition considerably improved after chemotherapy. Intravascular large B-cell lymphoma should be considered in patients with acute respiratory failure and interstitial lung lesions.

Introdução: As teleconsultas só foram permitidas pelos conselhos de classe no Brasil após o início da pandemia de Covid-19. A Atenção Primária (AP) de Florianópolis reunia as condições necessárias para realizar teleconsultas e foi a primeira capital a adotar esse modelo de atendimento em grande escala. Objetivo: Comparar as condições de atendimento e as características dos profissionais de saúde nas consultas realizadas na AP de Florianópolis por médicos e enfermeiros entre as teleconsultas e consultas presenciais. Metodologia: Estudo retrospectivo com todas as consultas realizadas por médicos e enfermeiros da AP no período de 15/04/2020 a 27/07/2020. Resultados: Analisamos 225.507 consultas realizadas por 436 médicos e enfermeiros. Profissionais, médicos e enfermeiros, que realizaram ao menos uma teleconsulta apresentaram maiores números de consultas, tempo médio de consulta pouco maior, bem como média de encaminhamentos e de exames solicitados por consulta discretamente maiores. Porém, as teleconsultas foram mais rápidas, tiveram menos exames solicitados, medicamentos prescritos e encaminhamentos realizados. As condições menos avaliadas por teleconsulta foram: rastreamento de câncer de colo uterino, cerume impactado, amigdalite e puericultura. As condições mais avaliadas, por médicos e enfermeiros, nas teleconsultas foram: hipotireoidismo, dispepsia, contracepção e dor não classificados. Conclusões: A teleconsulta é uma ferramenta útil para realização de atendimentos na AP e permite o atendimento de uma ampla gama de condições. É importante a realização de estudos dessa tecnologia neste período de exceção para embasar decisões futuras quando a sua manutenção após a pandemia.

Spotlights on the Amended Jordanian Arbitration Law of 2018: Is There Room for Further Amendments?
Authors: Ababneh Hisham
Published: August 2023

This article analyses some of the recent amendments made to the Jordanian Arbitration Law which came into effect in 2018. It highlights the Law’s degree of success in achieving the aspirations of both academics and practitioners in the field of arbitration. While this article concedes that the 2018 amendments were indeed a step forward to a more modern and up-to-date arbitration legal framework in Jordan, it takes the position that there remains some room for further development to overcome the shortcomings and issues that have not been addressed. This article concludes that the Jordanian legislature should aim at adopting the most recent trends and developments in international arbitration through feedback from all stakeholders in the arbitral process to achieve Jordan’s main goals of attracting foreign investment, stimulating the economy, and enhancing the use of arbitration as a tool for the settlement of disputes.
Privacy and the Standing to Hold Responsible
Authors: Radzik Linda
Published: August 2023

In order to be held responsible, it is not enough that you have done something blameworthy; someone else must also have the standing to hold you responsible. But a number of critics have claimed that this concept of ‘standing’ does not hold up to scrutiny and that we should excise it from our analyses of accountability practices. In this paper, I examine James Edwards’ (2019) attempt to define standing. I pose objections to some key features of Edwards’ account and defend an alternative. Reflecting on examples of meddling blame and privacy norms, I argue, helps us see that the concept of standing is useful after all.
The genus Tibicina Kolenati, 1857 in Morocco (Hemiptera: Cicadidae: Tibicininae): taxonomic assessment from integrative research
Authors: PUISSANT STEPHANE , GURCEL KEVIN
Published: August 2023

A new subspecies, Tibicina quadrisignata pilleti Puissant ssp. nov. is described from Morocco. This cicada is similar to Tibicina quadrisignata (Hagen, 1855) but differs mainly in the body color of the males and some acoustic parameters, notably in the courtship song. A complete pipeline is developed for detailed analysis of the morphology and acoustic behavior of the two Tibicina taxa currently known in Morocco, i.e. Tibicina quadrisignata (Hagen, 1855) pilleti Puissant ssp. nov. and Tibicina maldesi Boulard, 1981. Biology, ecology and distribution are presented for the first time for both taxa. Tibicina maldesi emits an abnormally high carrier frequency relative to its size. It could be an adaptation to avoid acoustic interference with a sympatric Tibicina species yet to be discovered or extinct.
A new Moenkhausia (Characiformes: Characidae) from rio Braço Norte, rio Tapajós basin, with comments on the fish endemism of Serra do Cachimbo plateau
Authors: LIMA ARTHUR DE , VITA GEORGE , DUTRA GUILHERME M. , OHARA WILLIAM M. , PASTANA MURILO N. L.
Published: August 2023

A new species of Moenkhausia is described from the rio Braço Norte, a tributary of Rio Teles Pires draining the Serra do Cachimbo, rio Tapajós basin, Pará, Brazil. The new species is diagnosed from all congeners, except M. moisae and M. pirauba, by having a high number of scales in the longitudinal series (43–46 vs. 23–41 in other Moenkhausia species). It can also be distinguished from the aforementioned species based on the combination of the following characters: a single humeral blotch, 21–25 branched anal-fin rays, and a round and symmetrical caudal blotch not continuous anteriorly with the dark midlateral stripe. The new tetra herein described represents an additional, possibly endemic, taxon from the headwaters draining from Serra do Cachimbo, in the Brazilian Shield.
Persecuted Minorities and Defensive Cooperation: Contributions to Public Goods by Hindus and Muslims in Delhi
Authors: Cammett Melani , Chakrabarti Poulomi , Romney David
Published: August 2023

How does intergroup inequality, specifically minority experiences of persecution, affect contributions to local public goods? Based on an original survey experiment and qualitative research in slums in Delhi, we examine how Hindus and Muslims respond to social norms around promoting cooperation on community sanitation. Mainstream theories of development predict greater willingness to contribute to public goods in more homogeneous areas. In contrast to the “diversity-deficit hypothesis,” however, we find that social accountability mechanisms are more effective among Muslims, a group that routinely faces discrimination and violence in India. We propose that this reflects “defensive cooperation,” or a set of coping strategies developed by minorities to navigate a hostile sociopolitical environment. Our findings point to a new mechanism that helps to enforce prosocial norms and, hence, public goods provision in multiethnic contexts.
Beyond institutions: Non-governmental organisations’ beneficiaries’ role in poverty reduction
Authors: Kabonga Itai
Published: August 2023

Studies done before tend to amplify the role of institutions in improving the welfare of individuals and families. Few studies interrogate the role of beneficiaries in micro-social work interventions. Using NGOs’ interventions as a case study, beneficiaries are going the extra mile to reap maximum benefits, and some of their actions are organic, spontaneous and context-specific and are not influenced by NGOs themselves. The findings deepen community practice by appreciating that NGOs’ beneficiaries can organise for social action in pursuit of household welfare. There are better outcomes when micro-social work builds on the potential of clients.
Changes in Perceptions of Border Security Influence Desired Levels of Immigration
Authors: Briggs Ryan C. , Solodoch Omer
Published: August 2023

Security concerns about immigration are on the rise. Many countries respond by fortifying their borders. Yet little is known about the influence of border security measures on perceived threat from immigration. Borders might facilitate group identities and spread fear of outsiders. In contrast, they might enhance citizens’ sense of security and control over immigration. We test these claims using survey experiments run on a quota sample of over 1000 Americans. The findings show that allocating more government resources to border security increases desired levels of immigration. This effect is likely driven by a sense of control over immigration, induced by border security measures even when the number or characteristics of immigrants remain unchanged. Our findings suggest that border controls, which are widely considered as symbols of closure and isolation, can increase public support for immigration.
Measuring Morality: An Examination of the Moral Foundation Questionnaire’s Factor Structure

Published: August 2023

Moral foundations theory proposes five domains of morality—harm, fairness, loyalty, purity, and authority. Endorsement of these moral domains is assessed by the Moral Foundations Questionnaire (MFQ), a 30-item scale that has undergone intense measurement scrutiny. Across five samples ( N = 464,229), we show greatly improved model fit using a Bifactor model that accounts for two kinds of items in the MFQ: judgment and relevance. We add to this space by demonstrating how using this improved measurement structure changes the strength of correlations of the moral foundations with numerous attitudes, cognitive styles, and moral decision-making. Future research should continue to identify what, if anything, the relevance and judgment factors might substantively capture over and above the substantive domains of moral foundations. In the meantime, we recommend that researchers use the Bifactor model for its improved model structure, rather than dropping the relevant items as some have proposed.
Attention, ambivalence and algorithms: Publishers in the era of ubiquitous connectivity and expanding platforms
Authors: Spjeldnæs Kari , Karlsen Faltin
Published: August 2023

This article scrutinizes how digitalization influences fiction and non-fiction literature publishers in the era of ubiquitous digital connection. The analysis states how a lack of attention is triggering a sense of urgency for the future of literary reading. Further, the digital transition entails an overarching ambivalence. Key stakeholders in literary publishing are experiencing how media on platform-based streaming services is competing with traditional reading. They perceive a battle for time and question the future of reading. From the perspectives of Bourdieu’s theory, the article reveals how penetrating connectivity is leading to a change in the professional habitus. Continuous busyness and increased professional presence are triggering ambivalence between work-related duties and personal well-being. Moreover, the publishing stakeholders reveal an ambivalence in voicing future expectations. While worried about the future of reading, the professional habitus leans on a promising future for the industry.
Re-meme-bering Tiananmen? From collective memory to meta-memory on TikTok
Authors: Seet Seth , Tandoc Edson C
Published: August 2023

The 1989 Tiananmen Square Massacre has been enshrined in the collective memory of different social groups globally in various ways, while the Chinese government enforces its own memory of Tiananmen through censorship and revisionism. These result in numerous memories of Tiananmen. Through a qualitative analysis of 27 TikToks posted on 3–5 June 2022, this study examines how Tiananmen is commemorated on TikTok on Tiananmen’s anniversary and what is remembered about Tiananmen. This study found that commemoration posts on TikTok remember the protests, casualties, the Chinese Communist Party leaders’ role, and the historical contexts, oft using the Tank Man image. The posts also remember the remembrance and memory formation of Tiananmen. Through commemorations, memes, and humor, some posts remember the Chinese government’s attempts to recreate the collective memory and other commemoration events. This is best described as meta-memories, where people remember the remembering and possess memory of the memory of events.

Contact planning is crucial to the locomotion performance of robots: to properly self-propel forward, it is not only important to determine the sequence of internal shape changes (e.g., body bending and limb shoulder joint oscillation) but also the sequence by which contact is made and broken between the mechanism and its environment. Prior work observed that properly coupling contact patterns and shape changes allows for computationally tractable gait design and efficient gait performance. The state of the art, however, made assumptions, albeit motivated by biological observation, as to how contact and shape changes can be coupled. In this paper, we extend the geometric mechanics (GM) framework to design contact patterns. Specifically, we introduce the concept of “contact space” to the GM framework. By establishing the connection between velocities in shape and position spaces, we can estimate the benefits of each contact pattern change and therefore optimize the sequence of contact patterns. In doing so, we can also analyze how a contact pattern sequence will respond to perturbations. We apply our framework to sidewinding robots and enable (1) effective locomotion direction control and (2) robust locomotion performance as the spatial resolution decreases. We also apply our framework to a hexapod robot with two back-bending joints and show that we can simplify existing hexapod gaits by properly reducing the number of contact state switches (during a gait cycle) without significant loss of locomotion speed. We test our designed gaits with robophysical experiments, and we obtain good agreement between theory and experiments.
Nomogram for predicting survival of patients with gastric cancer and multiple primary malignancies: a real-world retrospective analysis using the Surveillance, Epidemiology and End Results database

Published: August 2023

Objectives

Gastric cancer combined with multiple primary malignancies (GCM) is increasingly common. This study investigated GCM clinical features and survival time.

Methods

Patients with GCM and GC only (GCO) were selected from the Surveillance, Epidemiology and End Results (SEER) database. Survival was compared between GCM and GCO groups using propensity score matching. Then, the GCM group was divided into a training cohort and a validation cohort. These cohorts were used to establish a nomogram for survival prediction in patients with GCM.

Results

Survival time was significantly longer in the GCM group than in the GCO group. All-subsets regression was used to identify four variables for nomogram establishment: age, gastric cancer sequence, N stage, and surgery. The concordance index and time‐dependent receiver operating characteristic curve indicated that the nomogram had favorable discriminative ability. Calibration plots of predicted and actual probabilities showed good consistency in both the training and validation cohorts. Decision curve analysis and risk stratification showed that the nomogram was clinically useful; it had favorable discriminative ability to recognize patients with different levels of risk.

Conclusions

Compared with GCO, GCM is a relatively indolent malignancy. The nomogram developed in this study can help clinicians to assess GCM prognosis.
Private Worlds by Jeremy Seabrook: a response
Authors: Pelz Peter
Published: August 2023

This year, 2023, marks the sixtieth anniversary of Jeremy Seabrook’s authorial career as one of our finest and most impassioned writers on the nexus of the personal, the political and the global. And, it is just over three decades since he first wrote in Race & Class. With a depth and range that spans the life situation of the poor in Britain, the underprivileged and precariat of the Asian sub-continent, the impact of imperialism and consumerism on the psyche, the meaning of work, the impact of environmental disaster and the essence of what it is to be human – and a gift for striking prophecy – Seabrook’s career has been marked by the telling of beautifully expressed but often deeply uncomfortable and challenging truths. Yet always with immense feeling for the other at their heart. As expressed in his seminal piece, ‘The soul of man under globalism’ ( Race & Class 43, no. 4, 2002), ‘There are many macro-economic accounts of globalisation, but we rarely learn how it affects the psyche and sensibility of lives uprooted and radically reshaped by the penetration of their world by the market economy.’ We are therefore delighted to publish in this issue and this anniversary year, not only Jeremy Seabrook’s latest article for us, ‘The present imperium’, but also this response, by a contemporary, to his recently published autobiography, Private Worlds: growing up gay in post-war Britain (Pluto Press, 2023) which raises not only fundamental themes relating to the gay community in the UK and its history, but also profound, wider societal issues.

Authors: El Moghazy Hazem , Mahmoud Tarek , Mamdoh Ahmed , Rashed El Nisr , Eissa Mohamed
Published: August 2023

Objective:

To evaluate the functional and cosmetic outcomes of using the mini-laparotomy technique In Situ pyeloplasty to repair UPJ obstruction in young infants less than 6 months.

Materials and methods:

Between January 2014 and March 2020, 150 young infants (less than 6 months) diagnosed with unilateral ureteropelvic junction obstruction (UPJO) and treated by mini-laparotomy In Situ pyeloplasty were included in this analysis. Once the UPJ has been identified, it was grasped by an Allis forceps for gentle traction. Two facing transverse incisions were made in the dilated pelvis facing the upper ureter. The transverse ureteric incision was then opened longitudinally. An anastomosis was done between the most dependent part of the lower lip of the pelvis and the apex of ureteric spatulation using 6/0 polyglactin (Vicryl®) sutures in the direction of “out-in-in-out.” Follow-up was scheduled for 1 month and then every 3 months for a year with abdominal ultrasonography. DTPA was done for all patients 1 year after repair.

Results:

The mean age was 3 ± 0.5 months, and the mean follow-up was 1.5 ± 0.3 years. Our technique was done in all included patients with a functional success of 96% (all patients restored normal function, and no obstruction was reported). Parents were satisfied with the cosmetic appearance of the wound in 91% of cases. Major complications occurred in 4% of cases.

Conclusion:

Successful repair of ureteropelvic junction obstruction in young infants can be achieved by using mini-laparotomy In Situ pyeloplasty technique with satisfactory functional and cosmetic outcomes.
Kaleidoscopic Preaching: Incorporating Multiple Voices into an Evangelical Sermon
Authors: Redwood Christine
Published: August 2023

The sermon still dominates in many evangelical churches. Evangelical preachers seek to capture and communicate the author’s intention in the biblical text. This can be challenging because the Bible is multi-faceted. How can evangelical preachers acknowledge this multiplicity? Preachers need to be willing to play in both the text and the way they communicate. In this article, I propose a strategy I have named the kaleidoscopic approach. I draw on the feminist scholar Mieke Bal and her work on the song in Judges 5 and bring some of her ideas to preaching. I believe a kaleidoscopic approach can help to amplify marginal (often female) voices in the text and bring fresh thinking on how we can continue to preach in the future.
