Synthesis and tribological assessment of oil-based nanolubricants blended with nano-zeolite for steel–steel contact
Authors: Zhu Lin , Sun Yunyun , Wu Shijing
Published: July 2024

This study aims to synthesize zeolite with nano-sized morphology and investigate the tribological performance of nano-zeolite as a lubricating additive dispersed in an oil-based lubricant. Tribological tests were performed and morphologies of wear tracks were characterized to investigate the friction reduction and anti-wear properties of zeolite, respectively. The lubrication mechanism was discussed by illustrating the effects of concentration and particle size on the tribological behavior of zeolite. The optimal concentration of nano-zeolite to improve the tribological performance of the base oil was 2 wt.%, which exhibited a friction reduction of 34.3%. Zeolite particles with larger diameters showed better dispersion stability but worse lubrication performance, which could be concluded from the decrease in the friction reduction ratio. Moreover, the friction coefficient under the lubrication of zeolite at 200°C was 15.8% lower than that of the pure base oil, demonstrating the thermal stability of zeolite. Notably, the application of zeolite resulted in an increase in wear depth due to the occurrence of the three-body abrasion, while the surface asperities of the counterpart were also smoothed in the meantime. This work demonstrates the potential of nano-zeolite to enhance the tribological performance of oil-based lubricants in industrial applications, which could be attributed to their porous structure, lipophilicity, and chemical–thermal stability.
Collectivist Relationality and Individualistic Relationality: Pacific Mothers and Fathers Negotiating Agency and Identity in Post–Separation Care Arrangements for Children
Authors: Keil Moeata
Published: July 2024

The degree to which agency and identity are experienced as individualised or relational constructs have been widely debated in the sociological literature. Yet, at the centre of these debates are Western notions and understandings of individualisation and relationality, including in family research. They have relied on individualised and nuclearised understandings and approaches to being a family that more closely approximate the lives of white Western middle-class nuclear families. Drawing on semi-structured talanoa (akin to interviews) with separated heterosexual Pacific parents, specifically ten mothers and five fathers, living in New Zealand, I contribute to individualisation and relationality debates by examining how agency and identity are enacted following separation. In particular, I examine the way that Pacific mothers and fathers grapple with tenets of individualisation and relationality in terms of how and with whom they organise and negotiate care arrangements for children. My research demonstrates how Pacific gendered norms and values operated in ways that differentially shaped the kinds of decisions that mothers and fathers made about children’s care arrangements. I conclude with a discussion that highlights the significance of integrating cultural relationality into research on family life.
Prison places, foreign prisoners and the Danish welfare state: Towards a conceptualization of prison space as a welfare resource
Authors: Abellan-Almenara Meritxell
Published: July 2024

In December 2021, the government of Denmark entered into a rental agreement with Kosovo whereby 300 non-EU foreign nationals convicted by the Danish criminal justice system would be sent to Kosovo to serve their sentence of imprisonment and await their subsequent deportation. Based on an analysis of the wording of the Agreements on the finances of the Danish Prison Service, the article argues that a conceptualization of prison space as a welfare state's scarce resource makes it possible to explain such rental agreement through the theories of welfare and penal nationalism. In doing so, the article contributes to the growing body of literature that exposes the inherently dual harsh-but-mild nature of the penal regimes of Nordic welfare states. The article concludes with a brief outline of the future challenges that can potentially arise once the Denmark–Kosovo rental agreement enters into force.
The effect of climate change threat on public attitudes towards ethnic and religious minorities and climate refugees
Authors: Shanaah Sadi , Fritsche Immo , Osmundsen Mathias
Published: July 2024

How does climate change threat affect attitudes towards ethnic and religious minorities and climate change refugees? We show that threatening climate change can have deep psychological effects even among social majority groups in relatively prosperous and peaceful societies. Using three survey experiments with self-identified White British participants ( N = 616, N = 587, and N = 535), we demonstrate that social majority members who are exposed to threatening information about climate change (vs. neutral information) and, at the same time, feel little national efficacy over climate change, evaluate more negatively certain ethnic and religious minorities, especially Muslims and Pakistanis. We found the same trend in the evaluation of climate refugees, although it reached statistical significance only in one of the experiments. We explain these reactions as pertaining to groups that are perceived as threatening the salient ingroup and its collective agency. Our research significantly contributes to the literature on the social and political implications of (climate change) threat, especially by focusing on boundary conditions, namely the perception of collective control in case of complex and large threats.
Evaluating shear capacity in reinforced concrete deep beams with web openings strengthened using fiber-reinforced polymer and fiber-reinforced cementitious matrix
Authors: Le Dang Dung , Nguyen Xuan Huy , Nguyen Huy Cuong , Tran Cao Thanh Ngoc
Published: July 2024

This research systematically compares the effectiveness of Carbon Fiber-Reinforced Polymer (FRP) and Fabric-Reinforced Cementitious Matrix (FRCM) in shear strengthening of reinforced concrete (RC) deep beams featuring web openings. Through a comprehensive experimental program, six RC beams were subjected to shear tests, considering variations in the number of layers for both FRCM and FRP, employing a U-wrapping configuration. Recorded parameters include load-deflection curves, ultimate strength, cracking patterns, failure modes, and strains in steel bars, allowing a comprehensive comparison between strengthened and un-strengthened RC beams. The study compares observed shear strengths from experiments with shear capacities predicted by proposed models for RC beams strengthened with FRCM and FRP, following codes such as ACI 440.2R-17, CSA S806-12, Eurocode 2, and ACI 549.4R-20. Increasing layers enhanced shear strengths and post-elastic stiffness. The presence of substantial openings led to early shear cracks and reduced strength. CFRP improved shear strength by 13.99% (1-layer) and 18.12% (2-layer), while FRCM strengthened layers by 20.2% (1 layer) and 29.3% (2 layers). FRCM outperformed in strength and stiffness, while FRP excelled in ductility and concrete confinement. Experimental and calculated results varied based on ACI, CSA, and Eurocode, with ACI providing consistent and accurate results. CSA’s calculation surpassed experiments, emphasizing its consideration of effective fabric design strain.
Justice behind the virtual mask: The influence of race of the virtual influencer and the creator on promoting the Black Lives Matter movement
Authors: Hong Joo-Wha , Cruz Ignacio Fernandez , Kim Donggyu
Published: July 2024

The rise of virtual influencers is reshaping the landscape of social media, extending even to the promotion of social causes. Yet, lingering doubts persist regarding the authenticity of their motives. This research delves into the impact of both the racial identities of virtual influencers and those of their creators when linked to the support of racial movements. In terms of source credibility, results find that a creator’s racial background, but not that of a virtual influencer, plays a substantial role, and an interaction effect between these factors was identified. The results also show that individuals’ assessments of a virtual influencer and their message are influenced by the perceived social agency. We discuss the theoretical and practical implications of these findings.
Performance of polyvinyl chloride-based E-glass reinforced isophthalic and orthophthalic polyester sandwich composites: A comparative study
Authors: Ojha Somanath , Bisaria Himanshu , Mohanty Smita , Kanny Krishnan
Published: July 2024

This study investigates the performance of sandwich composites composed of polyvinyl chloride cores reinforced with E-glass fibers and bonded with isophthalic and orthophthalic polyester skins. The aim is to comparatively assess the mechanical and morphological characteristics of these composite structures. The comparative analysis also included variations in the skin thickness of the sandwich composite. Mechanical tests such as compressive, impact, and hardness were carried out. Moreover, fracture tests specifically focusing on single-edge notched beam fracture (mode I) were conducted under different temperature conditions, low (−10 °C), ambient (25 °C), and high (100 °C) temperatures. Comparative analysis of the mechanical properties indicated that the isophthalic-based sandwich composites exhibited superior mechanical characteristics when compared to their orthophthalic counterparts. Fracture properties of both types of sandwich composites demonstrated higher values at lower temperatures, followed by room temperature, and then high temperatures. In both types of sandwich composites, using two layers of E-glass on both sides of the polyvinyl chloride foam resulted in superior properties. This improvement can be attributed to the increased skin thickness. The interfacial properties were identified using Fourier transform infrared spectroscopy and scanning electron microscopy, revealing distinct spectroscopic features such as CH-stretching, C–O–C, CH bend, CN stretching, and NH stretching. Examination of the fractured surfaces through scanning electron microscopy revealed distinct features such as crushed fiber, fiber pull-out, honeycomb, riverline patterns, matrix-fiber delamination, and debonding, providing valuable insights into the composite's structural integrity.

Published: July 2024

In the area of plant engineering, steel components are provided with a wear protection coating for efficient use to protect them against corrosive, tribological, thermal and mechanical stresses. The use of innovative ultrasound-assisted milling processes and plasma-welded nickel- and cobalt-based wear protection coatings are being investigated to determine how more favourable machinability can be achieved while retaining the same wear protection potential. The focus is on the NiCrSiFeB alloy, which is intended to replace CoCr alloys in the area of screw machines. The utilization of ultrasonic-assisted milling for the machining of coating materials is a novel approach. The modification of hard facing layers in terms of microstructure and precipitation morphology as well as suitability for machining is investigated and compared with the CoCr alloy. The alloy modifications are generated by a PTA process by systematically adjusting the preheating and interpass temperatures, a crack-free wear-resistant layer can be generated, which is subsequently machined by a milling process. In addition to the crack-free properties, the microstructure, the bonding as well as the mixing between the NiCrSiFeB alloy and a 1.8550 as well as between the CoCr alloy and a 1.4828 are analysed and compared in the joining areas. In addition, heating and cooling rates are determined and a chemical analysis of the weld metals is performed. Furthermore, it was found that the build-up layers of NiCrSiFeB alloy are more difficult to machine using the milling process than the CoCr alloy, as higher milling forces are required.
Social work with Irish Travellers: Findings from a national evaluation
Authors: Campbell Jim , Kelleher Joanne , Norris Michelle , Palmer Angela
Published: July 2024

This article reports on the findings from a national evaluation of a specialist, Irish, social work service for Traveller families and communities. It begins with an historical overview of the service which was established in the 1960s but which has evolved and developed over the past few decades at a time of changing patterns of Traveller lives and social and economic conditions. It was also a period when the role of social work was changing, most notably with the introduction of state regulation of the profession. The article then critically analyses national and international literature on the role of social workers with Travellers. It then describes the mixed research method used to evaluate the service.

Findings

The findings highlight various, sometimes competing perspectives on the social work role, drawn from administrative data, a survey of social workers interviews with social workers and Traveller representatives. These include views about how the social work role was viewed by social workers and Traveller representatives, informed by theories on anti-oppressive practice, systems approaches and forms of advocacy.

Applications

The article concludes with a discussion of ways in which the lessons learned from the evaluation can be used to further develop the social work service in ways that can enhance the lives of Travellers, through forms of continuous professional development and the created of a national policy and practice framework.
Following the sounds of children’s “voices”: A researcher’s portfolio
Authors: Dyson Anne Haas
Published: July 2024

Herein, I explore the meanings of the oft-used phrase “children’s voices.” The phrase is seldom defined in the literature on children’s language, oral and written. And yet, studying those voices has been fronted as a key methodological tool allowing insights into concerns about equity and the erasure of “nonmainstream” children’s communicative resources. Thus, this essay examines the professional use of “children’s voices” by taking readers on a voice-filled journey through time and space as I consider literally how this unstable but valuable phrase (e.g., “children’s voices”) is used to index some quality of children’s language use, especially their multimodal composing. First, I report on a literature analysis, focused on a relatively recent decade of articles from the National Council of Teachers of English (NCTE)’s journal focused on children, Language Arts (the decade beginning in 2010). Although it proved to be a relative rarity to identify an author defining “children’s voices,” this project phase was invaluable for developing a taxonomy of non-rigidified but still differentiated categories for the meaning of “children’s voices.” Next, to clarify this unstable but useful taxonomy, I examined my ethnographic reports written over 46 years of studying children’s talk and writing, selecting excerpts from four chronologically organized reports, which were undergirded by different stances toward “children’s voices.” Together they illustrate how going deeper into children’s voices meant expanding the nature of the sociopolitical and cultural worlds enacted, sustained, or interrupted by children’s contextualized voices. As Hymes said many years ago, to understand voice and how it figures into equity issues in education, one needs ethnographic context. I aim to suggest why clarity about voice matters theoretically, politically, and pedagogically if we are to understand children’s composing of both texts and themselves as participants in a shared world.
Joyriding Among Young First Nations Australians: Assessing Police Trust and Confidence Through the Lens of Youth and Key Stakeholders
Authors: Morgan Matthew M. , Dodd Shannon
Published: July 2024

Young First Nations Australians typically distrust and are reluctant to cooperate with the police. This article discusses data from a pilot intervention programme regarding First Nations young people’s involvement in car theft and joyriding. We conducted seven in-depth interviews with young Australians – most of whom identified as First Nations Australians – and six key community stakeholders who helped to deliver the programme. Our findings indicate that both sample groups held negative and distrusting perceptions of the police which, for the young people, were often precipitated by perceived discriminatory and procedurally unjust encounters with the police. We argue that heavy-handed and discriminatory policing of young First Nations Australians may perpetuate youth offending and joyriding behaviours among this group. The article argues that the police should adopt more community-oriented policing approaches to build trust with young First Nations Australians.
Early Indicators of Study Delay and Dropout: Test Anxiety and its Link to Exam Participation and Performance

Published: July 2024

This study examined the relationship between test anxiety and early indicators of dropout at the largest distance university in Germany. Specifically, we examined how test anxiety correlated with first-year students’ intention to take their first exam, the postponement of it and their performance in it ( N = 542). Results indicated a negative association of (motivational) test anxiety with students’ intention to sit the exam. The postponement of the exam did not correlate with test anxiety. However, our results suggest that male students and students with a migration background were more likely to postpone the exam when test anxiety was high. Furthermore, we observed a strong negative association between (motivational) test anxiety and performance. Additionally, there was a negative association of the intention to sit the exam and exam postponement. Participation intention weakened the negative association between test anxiety and performance. Our findings provide insights for developing interventions aimed at reducing dropout.
Subnational Investments in Mitigation and Adaptation to Climate Change: Some Financing and Governance Issues
Authors: Mello Luiz de , Ter-Minassian Teresa
Published: July 2024

Meeting climate change goals requires steadfast action at all levels of government in terms of both mitigation (measures to reduce greenhouse gas emissions) and adaptation (measures to reduce the impacts of climate change on economies and societies). Against this background, this paper discusses the role of subnational investment, including funding and financing options, as well as governance arrangements. It fills a gap in scholarly work on the principles guiding subnational investment in climate change mitigation and adaptation, identifies areas for future work, and underscores the need for cross-country comparable information on policy instruments and outcomes at the subnational levels of administration that could be used in more systematic hypothesis testing in this area.

Male breast cancer (MBC), one of the rare types of cancer among men where the global incidence rate is 1.8% of all breast cancers cases with a yearly increase in a pace of 1.1%. Since the last 10 years, the incidence has been increased from 7.2% to 10.3% and the mortality rate was decreased from 11% to 3.8%. Nevertheless, the rate of diagnoses has been expected to be around 2.6% in the near future, still there is a great lack in studies to characterize the MBC including the developed countries. Based on our search, it is evidenced from the literature that the number of risk factors for the cause of MBC are significant, which includes the increase in age, family genetic history, mutations in specific genes due to various environmental impacts, hormonal imbalance and unregulated expression receptors for specific hormones of high levels of estrogen or androgen receptors compared to females. MBCs are broadly classified into ductal and lobular carcinomas with further sub-types, with some of the symptoms including a lump or swelling in the breast, redness of flaky skin in the breast, irritation and nipple discharge that is similar to the female breast cancer (FBC). The most common diagnostic tools currently in use are the ultrasound guided sonography, mammography, and biopsies. Treatment modalities for MBC include surgery, radiotherapy, chemotherapy, hormonal therapy, and targeted therapies. However, the guidelines followed for the diagnosis and treatment modalities of MBC are mostly based on FBC that is due to the lack of prospective studies related to MBC. However, there are distinct clinical and molecular features of MBC, it is a need to develop different clinical methods with more multinational approaches to help oncologist to improve care for MBC patients.

Published: July 2024

Spinal cord astrocytoma (SCA) is a rare subtype of astrocytoma, posing challenges in diagnosis and treatment. Low-grade SCA can achieve long-term survival solely through surgery, while high-grade has a disappointing prognosis even with comprehensive treatment. Diagnostic criteria and standard treatment of intracranial astrocytoma have shown obvious limitations in SCA. Research on the molecular mechanism in SCA is lagging far behind that on intracranial astrocytoma. In recent years, huge breakthroughs have been made in molecular pathology of astrocytoma, and novel techniques have emerged, including DNA methylation analysis and radiomics. These advances are now making it possible to provide a precise diagnosis and develop corresponding treatment strategies in SCA. Our aim is to review the current status of diagnosis and treatment of SCA, and summarize the latest research advancement, including tumor subtype, molecular characteristics, diagnostic technology, and potential therapy strategies, thus deepening our understanding of this uncommon tumor type and providing guidance for accurate diagnosis and treatment.

Authors: Qin Rong , Yin Liang , Wang Deqian , Cao Xuan , Shaibu Zakari , Wang Xiangyang , Chen Peiqin , Sui Danjuan , Qiu Xiaoxi , Liu Dan
Published: July 2024

Background

Mastectomy (MT) and breast conservation surgery (BCS) are two common surgical options for the treatment of locally advanced breast cancer (LABC). Neoadjuvant chemotherapy (NACT) is frequently administered before surgery to shrink tumors and improve surgical outcomes. However, there is a lack of consensus on the optimal surgical approach after NACT and its impact on survival outcomes.

Objective

This meta-analysis aims to compare the survival outcomes between MT and BCS in patients treated with NACT.

Method

A PRISMA selection was used to identify studies across electronic database such as PubMed, and Cochrane Library from inception until 11th July, 2023. A total of 10 comparative studies involving a total of 5018 patients were included. Among them, 2898 patients underwent MT while 2120 underwent BCS after receiving NACT. The outcomes assessed were the 5-year overall survival (OS) and 5-year disease-free survival (DFS). The data from the included studies were pooled, and odds ratios (OR) with 95% confidence intervals (CI) were calculated to evaluate the differences between MT and BCS in terms of survival outcomes. Prospero: CRD42024496831.

Result

The meta-analysis revealed that patients who underwent MT after NACT had a higher 5-year OS compared to those who underwent BCS (OR 2.68, 95% CI [2.19-3.28; p < 0.00001]). Additionally, the 5-year DFS was significantly better for patients who underwent MT (OR 3.11, 95% CI [1.80-5.38; p < 0.0001]).

Conclusion

MT after NACT may be associated with better 5-year OS and DFS compared to BCS.

Published: July 2024

Objective: In external radiotherapy, dose boluses and compensators are used for treatment of irregular facial topography surfaces. In such cases, skewed isodose curves need to be addressed using a bolus that gives the deep dose distribution a shape adapted to the anatomical structures to be protected or irradiated. The combination of 3D modeling and printing technologies is a promising alternative to the conventional inaccurate and uncomfortable bolus fabrication technique. In this work, the proposed technologies will be used in the design and fabrication of high-performance and high-accuracy boluses that respond to the main constraints on metrology, adhesion to the patient's surface, comfort, and dose delivery. Methods: As a first phase in the implementation of the proposed solution, 3D printing materials, to be used in the fabrication of radiotherapy boluses, were selected and characterized to check how they respond to the required criteria on functionality, safety, and quality. Results: The obtained results show that among the studied materials, thermoplastic polyurethane (TPU) was found to be slightly more suitable than polylactic acid (PLA) for the fabrication of 3D printing boluses but for some kinds of treatments, PLA may be preferred despite its relative rigidity. Conclusion: In this work, procedures for dose bolus fabrication were proposed, and necessary data were obtained for some available 3D printing materials (TPU and PLA) that can be used for targeted applications. This achievement is a major step toward the final implementation of 3D modeling and printing technologies for the efficient fabrication of radiotherapy dose boluses.

Authors: Chun Yung , Jabbari Jason , Foell Andrew , Nandan Pranav , Chen Yi , Grinstein-Weiss Michal
Published: July 2024

Leveraging novel case management data, we present the first comprehensive investigation into the role of case management services in housing relocation and return decisions within the framework of the Choice Neighborhoods Initiative (CNI), the current place-based public housing revitalization program. Our study employs multinomial logistic (MNL) regression models to demonstrate that a higher level of involvement in case management services is correlated with an increased probability of moving to a higher-income neighborhood during the redevelopment process, as well as a greater likelihood of returning to the revitalized neighborhood afterward. By achieving these outcomes, case management services play a crucial role in enhancing the chances for original CNI residents to reap the benefits of neighborhood redevelopment—a matter of enduring concern among social scientists. These findings are contextualized with both sociodemographic and neighborhood characteristics associated with relocation and return decisions.
Charles Darwin, Percy Grainger, and John Blacking: Reflections on the Historical Emergence of Music as a Human Universal
Authors: Bannan Nicholas
Published: July 2024

Music from every culture throughout history is now available at the click of a mouse. Prior to the development of recording, the unfamiliar largely separated musical cultures. This paper sets out a narrative to illustrate the framework through which a universalist approach to music emerged over the period 1871–1970, derived from placing in relation to one another accounts of the influence of three historical figures. The first is Darwin, whose theories of evolution embraced speculation on the origin and purpose of music, and who himself wrote about the effect on him of encountering unfamiliar musical styles in the Southern Hemisphere. The second is Grainger, influenced by Darwin’s work and persuasively concerned to open musical contact between all cultures. The third is Blacking, a pioneer in ethnomusicology and commentator on Grainger’s ideas. Tracing the links between these authors inevitably represents an English-language historical perspective on the issues of colonization, cultural appropriation, and the educational influence of a dominant culture. In offering such a historical account of fluctuating experience of ‘the other’ in music, the aim is to illustrate these authors’ contribution towards convergence on an open, informed position consistent with viewing musical exchange from a universalist perspective.

Introduction

Age is often used as a predictor in determining outcomes in large vessel occlusions treated with mechanical thrombectomy. However, limited data exist for octo/nonagenarian outcomes compared to younger individuals in acute basilar artery occlusions treated with thrombectomy.

Methods

Patient data were obtained from the PC-SEARCH Thrombectomy Registry which consists of 444 acute basilar artery occlusions treated with mechanical thrombectomy. Individuals were dichotomized based on age (>80 and ≤80 years old). Primary outcome was defined as modified Rankin Scale of 0–3 at 90 days. Logistic and multivariate regression, as well as control-matched analysis, were performed.

Results

There were 373 and 71 patients in the younger and older cohorts, respectively. Gender, ethnicity, smoking status, atrial fibrillation, and coronary artery disease were noted to be significantly different between cohorts. At 90 days, 178 (47.7%) and 23 (32.4%) patients achieved primary outcome at 90 days (p = 0.02), however, after controlling for potentially confounding factors this association lost significance (OR 0.50 95% CI 0.24–1.05; p = 0.07). There were 84 patients included in the control matched analysis and demonstrated no significant differences on multivariate analysis between cohorts (OR 0.68 95% CI 0.25–1.84; p = 0.45).

Interpretation

Octa/nonagenarians presenting with an acute basilar artery occlusion treated with mechanical thrombectomy can achieve acceptable rates of favorable functional outcomes compared to younger individuals with similar baseline demographic and stroke characteristics.

Effect of colored noise on precursors of thermoacoustic instability in model gas turbine combustors
Authors: Vishnoi Neha , Gupta Vikrant , Saurabh Aditya , Kabiraj Lipika
Published: July 2024

In this work, we numerically investigate the dynamics of a prototypical thermoacoustic system, the generalized Van der Pol oscillator, in the presence of additive noise of varying color (correlation time) and intensity while the system undergoes supercritical and subcritical Hopf bifurcation. We specifically investigate the influence of noise color on trends in the coherence factor and the Hurst exponent in the subthreshold region to assess their reliability as instability precursors. The Hurst exponent is found reliable only for correlation times much larger than the time scale of the instability while the coherence factor is found to be reliable for the entire range of noise color investigated. These inferences are found to hold for both supercritical and subcritical bifurcation cases.
Authoritarian Nostalgia and Democratic Decline in Contemporary Indonesia

Published: July 2024

This paper investigates the phenomenon of authoritarian nostalgia in Indonesian politics. Drawing on data from a Populi Center public opinion survey, we explore the characteristics, patterns and workings of authoritarian nostalgia. On the one hand, we find authoritarian nostalgia prevalent in the survey data and also anecdotally. Many in the public remember the New Order era fondly and have positive impressions of President Soeharto despite 32 years of military authoritarian rule. At the same time, we find that much of the nostalgia revolves around economic issues. Furthermore, our study shows that key age cohorts who lived during the New Order period have the most support for the authoritarian era. This paper also contributes to our understanding on how Indonesian people perceive and behave to their current Indonesian political development.
The Business of Governing Penang: Workarounds as Remedy?
Authors: Chan Xin Ying , Weiss Meredith L. , Yeoh Tricia
Published: July 2024

The state of Penang, including city councils for island Pulau Pinang (with urban-core George Town) and mainland Seberang Perai, has negotiated at least a degree of political marginalisation since independence. Ruled previously by a secondary partner in the ruling Barisan Nasional (National Front), and since 2008, by the Democratic Action Party and its coalition partners, the economically powerful state has negotiated constrained autonomy and resources. While to some extent, these governing challenges are common to all states in Malaysia's highly centralised federation, in other ways, they reflect Penang's specific political position. Penang's leadership has sought in particular ways to circumvent inertia or divided loyalties among bureaucrats from the federal, rather than a state-level, civil service. Central to that solution has been reliance on an array of state government-linked corporations, facilitating administration, but at possible cost to clear accountability, transparency, and promised empowerment of civil society.
Pharmacodynamic Materials and Mechanisms of Compound Scutellariae Radix Granules for Colorectal Cancer: A Network Pharmacology, Molecular Docking and Cell Experiments Study
Authors: Xing Yadong , Wu Min , Zhong Shijie , Zhang Hui , Zheng Aiping
Published: July 2024

Background: Compound Scutellariae Radix Granules (CSRG) are used to treat gastrointestinal diseases, including colorectal cancer (CRC), which is the second leading cause of cancer-related deaths. Studies have demonstrated that CSRG have anti-CRC effects; however, the exact molecular mechanisms remain unclear. Methods: This study used network pharmacology and molecular docking to identify the active ingredients in CSRG and assess CRC-related genes and pathways. After that, the effect of CSRG on HT29 cells was observed in vitro. Cell Counting Kit-8 detection, Western blot, and flow cytometry with AnnexinV-FITC/PI double staining experiments were used to observe the effects of CSRG on the proliferation, apoptosis and other effects of HT-29 cells. Moreover, the effects of CSRG and IGF-I (PI3K/AKT agonist) on HT-29 cell biological behaviors were gauged. Results: Naringenin, quercetin, licochalcone A, acacetin, wogonin, baicalein, kaempferol, and isorhamnetin were the key active ingredients in CSRG, which affect CRC through five genes: mitogen-activated protein kinase 3 and 1, tumor protein 53, signal transducer and activator of transcription 3, and RELA proto-oncogene, NF-kB subunit. The molecular docking experiments predicted the activity of the active ingredients in CSRG against their intended target, each of which could stably bind the corresponding CRC target. The enrichment analysis indicate that CSRG played a synergistic effect in regulating the process of apoptosis and cell proliferation, and that multiple pathways were participated in CSRG-related CRC treatment. Cell experiments results demonstrated that the PI3k–Akt pathway may be critical pathways. Besides, Tp53 was found tightly linked to apoptosis. Moreover, the suppressive effect of CSRG on HT29 cell malignant phenotypes was reversed by IGF-I. Conclusion: CSRG are an anti-colon cancer herb containing multiple components, involving multiple target genes and signaling pathways. CSRG inhibited colon cancer cell proliferation and induced apoptosis, which may be related to its inhibition of the PI3K/Akt pathway and activation of the Tp53 pathway.

Objective

Hydroxytyrosol (HT), a polyphenolic component identified in olive oil and leaves, represents one of the most extensively investigated natural phenol due to its diverse beneficial biological properties. Recent studies have shown that HT exhibits protective effects on reproductive function and can improve sperm quality. However, the precise effect and underlying mechanism of HT on oligozoospermia remain unclear. This study aims to investigate the effect and mechanism of HT across varying concentrations on oligozoospermia.

Methods

Oligozoospermia was induced in ICR male mice via intraperitoneal injection of busulfan (BUS, 30 mg/kg). The mice were randomly categorized into five groups as Normal, BUS, HT 10 mg/kg, HT 30 mg/kg and HT 50 mg/kg. The efficacy of HT on oligozoospermia was assessed through sperm concentration and motility using a computer-assisted sperm analysis system. Testicular and epididymal histology was examined via hematoxylin-eosin staining, while cytoskeletal integrity was evaluated by immunofluorescence. Hormone levels, along with reactive oxygen species (ROS) and malondialdehyde (MDA) were examined by ELISA kits. Differentially expressed genes were identified through RNA sequencing, and the expression levels of key genes were validated by qPCR.

Results

The results indicated that HT (50 mg/kg) significantly increased sperm concentration, promoted morphological recovery of testicular tissue, heightened the levels of serum testosterone, follicle-stimulating hormone, luteinizing hormone, as well as decreased the accumulation of ROS and MDA in mice with oligozoospermia. RNA sequencing analysis and RT-qPCR results revealed that HT could restore spermatogenesis and ameliorate oligozoospermia by up-regulating genes related to cilium organization, microtubule-based movement, and spermatid differentiation and development.

Conclusions

HT demonstrates therapeutic efficacy against busulfan-induced oligozoospermia. The mechanism of HT on oligozoospermia may be related to its influence on cilium and microtubule-based movement, along with the differentiation and development of spermatids. HT shows potential as a prospective therapeutic intervention for the treatment of oligozoospermia.
When Information Subsidies Go Live: Conceptualizing the Strategic Role of Personal Storytelling
Authors: Thorbjørnsrud Kjersti
Published: July 2024

This conceptual article argues that the strategic use of personal storytelling to attract public attention and gain political impact is insufficiently theorized in political communication, journalism studies, and lobbying research. Claiming the need to study backstage relations among interest groups, professional communication workers, journalists, and decision-makers, it conceptualizes how lay personal stories, with strong moral appeal and claim to authenticity, constitute a powerful form of live information subsidy in both indirect and direct communication strategies to influence decision-makers. Extending the classic theory of information subsidies, the article unpacks the particular value of personal storytelling regarding credibility, legitimacy, and appeal and hypothesizes how and when interest groups select, craft, exchange, and communicate lay personal stories to create public support and influence political decisions. The theorization of strategic personal storytelling is based on the synthesis of distinct research literatures and abductive multi-sited field studies of Norwegian interest groups, government communication, and journalistic source relations, heading the calls for more mixed-method, cross-disciplinary research to advance political communication overall.

Exploring the performance of bio-based PLA/PHB blends: A comprehensive analysis
Authors: Gao Luyao , D Drozdov Aleksey
Published: July 2024

Poly(lactic acid) (PLA) is a bio-based linear aliphatic polyester that is broadly used in biomedical applications. A shortcoming of PLA is its brittleness and low toughness. Poly(hydroxybutyrate) (PHB) is a microbial bioprocessed and biodegradable polyester. To enhance toughness of PLA, it was melt-blended with PHB-based thermoplastic elastomer in various proportions by using a twin-screw extruder. Scanning electron microscope images reveal that PLA forms a continuous phase in PLA/PHB blends reinforced with inclusions of PHB. Fourier transform infrared spectroscopy measurements demonstrate strong intermolecular interactions between PLA and PHB chains. Differential scanning calorimeter thermogramms show that PHB reduces the glass transition temperature of PLA and affects its crystalline structure. When the mass fraction of PHB was 20, the glass transition temperature of the blend decreased to 33.9°C. Rheological measurements demonstrate that blending of PLA with PHB changes qualitatively the dependence of its viscosity on shear rate. Quasi-static (uniaxial tension) and dynamic (impact) tests confirm that blending of PLA with PHB results in a noticeable (by a factor of three) increase in its impact toughness and causes transition from the brittle to ductile regime of fracture. When the mass fraction of PHB was 40, the impact toughness reached to 0.40 kJ/m2, almost 3 times to neat PLA.
Buddha's ear illusion: Immediate and extensive earlobe deformation through visuotactile stimulation
Authors: Kodaka Kenri , Sato Yutaro
Published: July 2024

The classical body ownership illusion, such as the rubber hand illusion, is achieved through appropriate proprioceptive displacement within temporal and spatial constraints that do not exceed the limits of proprioceptive flexibility. In the 2023 Best Illusion of the Year Contest, we introduced Buddha's ear illusion (BEI), which creates the illusion of owning a dramatically deformed earlobe through immediate visuotactile stimulation and seemingly challenges classical proprioceptive boundaries. The laboratory experiment examined the mechanics of this illusion, revealing a significant interaction between tactile earlobe pulling and visual miming that contributed to the enhanced perception of earlobe stretch. Importantly, 88% of the participants confirmed the illusory earlobe stretch (a rating of +4 or higher on a 7-point scale). More than half reported an earlobe descent of >10 cm within a 10-s visuotactile stimulation. The findings suggest that BEI operates on a distinct principle separate from proprioceptive modulation in contrast to classical ownership illusions.

The Chinese Origin of Xue (Learning)
Authors: Huang (黄晓珠) Xiaozhu
Published: July 2024

Highlights

The concept of xue (学) played a central role in Chinese education. Through the analysis of this key concept, we can further explain the internal differences between Chinese and Western educational cultures and systems. By mastering numerical divination techniques, shi (historians, 史) recast their role from that of sorcerers to that of civil officials. Such a shift laid the foundation necessary for xue to transform from a venue for military decision-making into a place for cultural and educational engagement after the Western Zhou Dynasty. In addition to shaping its core philosophical spirit, the origin of xue established its significance in traditional Chinese social and cultural contexts. It has contributed to the formation and transformation of the concept of de (virtue, 德) and continues to exert a great influence on contemporary Chinese education.
