Food Security in the Afro-China Cooperation: The Hanging, Untapped ‘Win-Win’ Partnership
Authors: Oluoko-Odingo Alice A. , Ayiemba Elias HO.
Published: March 2023

China-Africa cooperation, is a story of many successes, while also raising many eye-brows, as the world comes into terms with the alternative approach to development aid. The indebted African countries, hitherto considered unsuitable for funding by the west have had a fall-back position with China and successfully applied for development funding to support mainly infrastructure projects. Livelihood sustainability (food security) is therefore neglected, herein referred to as the hanging and untapped ‘win-win’ opportunity for partnership. The article is based on secondary data and adopts the theories of human-ecological system model and the sustainable livelihoods approach. In the discussions, some of the global challenges in the Afro-China cooperation, besides food security, include climate change, trade imbalance, migration and deforestation, which require multidisciplinary approach to handle. The conclusions underlined prioritizing of food security by leveraging on synergies within sustainable development goals for sustainability. Careful evaluation of new future partnerships is recommended.
Cicero’s Philosophical Leadership, an Academic Consideration
Authors: Thomas Charlotte C. S.
Published: March 2023

In Pro Murena, Cicero argues that Cato’s rigid philosophical comportment to politics reflects a mistaken understanding both of philosophy and of politics. By implication, he suggests that there is an approach to philosophy that is compatible with political leadership. Specifically, he argues that a thoroughgoing commitment to the philosophy of the Platonic Academy (i.e., Academic Philosophy) is entirely compatible with a thoroughgoing commitment to political leadership in the late Roman Republic. This essay looks at the most famous treatment of philosophical leadership in the Platonic corpus, the philosopher ruler of the Republic, and asks to what extent Cicero’s depiction of politics and philosophy is consonant with that account.
Nepos, Atticus, and the Quiet Life
Authors: Seal Carey
Published: March 2023

Cornelius Nepos’ Life of Atticus shows its author as living a life of deliberate withdrawal from politics. This paper compares that life to other models of political withdrawal in Greco-Roman thought and finds that it does not cohere very closely with any of them. Nepos, the paper proposes, deviates from these existing models in showing Atticus as avoiding politics not out of a desire to transcend human life, to reorder politics, or to create a substitute politics of his own, but rather to live what the paper calls ‘social life.’ Atticus embraces human interdependence while rejecting the civic forms in which that interdependence was traditionally expressed in Greece and Rome.
Machiavelli’s Catilinarian Oration
Authors: Scott John T.
Published: March 2023

In the Discourses on Livy, Machiavelli claims that writers who are afraid to condemn Caesar instead criticize Catiline. I argue that Machiavelli follows this advice by inverting it. He openly condemns Caesar and the empire he founded while signaling that he has in mind another inimical example: the Church. He signals his intention by echoing Cicero’s fourth Catilinarian oration, imitating Cicero’s image of the ruin of Rome if Catiline’s conspiracy were to succeed through his own vision of the Italy wrought by wicked Roman emperors who succeeded Caesar. The reader of Machiavelli who recognizes this echo is in a position to see Machiavelli’s own Catilinarian oration against another successor of Caesar. In making my argument, I draw on Rex Stem’s treatment of the functions of exemplementarity as employed by authors of texts and as received by their readers.
A New List of the High-Priests of Ptah at Memphis till the End of the Ancient Egyptian History (332 BCE)
Authors: EI-Sharkawy Basem Samir
Published: March 2023

It is well known that the Western coast of the Arabian Gulf in ancient times -3000 BCE and afterwards- has witnessed the establishment of many urban centers, which had some commercial relationships with its counterparts in Mesopotamia in the north, and with Indus civilization - present Indian Peninsula and Pakistan- in the south, in addition to its commercial relationship with the inner parts of the Arabian Peninsula.

This research paper is concerned more with the inscriptions of the urban centers -known as the Dilmun civilization- located on the Western Coast of the Arabian Gul£ Such inscriptions have not been studied before from a national point of view.

This research depends mainly on the Sumerian sources, which made several references to the economic, military and religious relationships with the Dilmun Civilization. This study aims to gather information about the Dilmun civilization in order to understand it more fully, and to shade light on the historical values of those archival sourcesw to the end of the Iron Age in the relevant archaeological sites on the western coast of the Arabian Gulf.
Application of Iron Oxide Nanoparticles in the Surface-Assisted Laser Desorption and Ionization–Mass Spectrometry of Small-Molecule Compounds
Authors: Tang Junchao , Shen Yulin , Xu Xu
Published: March 2023

Iron oxide nanoparticles were applied to the surface-assisted laser desorption and ionization–mass spectrometry (SALDI–MS) of small-molecule compounds, such as oligosaccharides, phytohormones, flavonoids, triglycerides, phospholipids, and amino acids. The spatial distribution
of small-molecule compounds in soybean was further studied by using imaging mass spectrometry. After different preparation methods were compared, iron oxide nanoparticles calcined at 300 °C were selected. Results showed that in SALDI–MS analysis, iron oxide nanoparticles were characterized
by good stability and low background noise. Analysis was performed in the positive ion mode at the laser energy of 70% with the average spectrum accumulated 30 times. The results showed that iron oxide nanoparticles had good repeatability and sensitivity in the analysis of the abovementioned
small-molecule compounds. Four samples, namely, sucrose, abscisic acid, DL-aspartic acid, and 1,2-dipalmitoyl-sn-glycerol-3-phosphorylcholine, were analyzed via SALDI–MS. The spot-to-spot repeatability RSD was less than 2.8%, and the interpoint repeatability RSD was less than 5.2%. The
linear correlation coefficient of the four samples was R2 > 0.993 within the concentration range of 0.05–1.0 mg/mL. On the basis of these results, the distribution of small-molecule components in soybean cotyledon, radicle, and germ was analyzed through SALDI–MSI.
Simulating the Hydrologic Response to Climate Change in Three New Zealand Headwater Basins Using CMIP6 Datasets
Authors: Risley John C. , Zammit Christian
Published: March 2023

Air temperature and precipitation outputs from 10 CMIP6 GCMs were input to the Precipitation-Runoff Modeling System hydrologic model to evaluate water and energy responses in three headwater basins to projected climate change over the twenty-first century. The headwater basins (398–801 km2) are located within the Mataura River basin in the South Island of New Zealand. CMIP6 datasets included two emission scenarios [shared socioeconomic pathways (SSPs) SSP2-4.5 and SSP5-8.5]. Half of the 10 GCMs selected in the study have equilibrium climate sensitivity (ECS) values above 4.5°C, which has been considered the upper end of equilibrium climate sensitivity. Modeling results included increased annual air temperature, evapotranspiration, and precipitation by the end of the twenty-first century for both SSP emissions scenarios, both high- and low-ECS GCMs, and all three headwater basins. Monthly precipitation and evapotranspiration totals also increased for all or most months. Monthly streamflow changes generally corresponded with monthly precipitation changes. Snowpack decreased significantly in depth and seasonal duration in all basins. However, streamflow increased for all SSP and ECS groups and basins because increased precipitation was consistently greater than increased evapotranspiration losses. Sources of uncertainty include the GCMs, climate sensitivity, downscaling, bias adjustment, emission scenarios, and the hydrologic model. Simulated hydrologic responses based on climate data from GCMs with ECS values of greater than 4.5°C could be less plausible since previous studies have suggested true ECS ranges from 1.5° to 4.5°C.
The Use of Ensemble Clustering on a Multimodel Ensemble for Medium-Range Forecasting at the Weather Prediction Center
Authors: Lamberson William S. , Bodner Michael J. , Nelson James A. , Sienkiewicz Sara A.
Published: March 2023

This article introduces an ensemble clustering tool developed at the Weather Prediction Center (WPC) to assist forecasters in the preparation of medium-range (3–7 day) forecasts. Effectively incorporating ensemble data into an operational forecasting process, like that used at WPC, can be challenging given time constraints and data infrastructure limitations. Often forecasters do not have time to view the large number of constituent members of an ensemble forecast, so they settle for viewing the ensemble’s mean and spread. This ignores the useful information about forecast uncertainty and the range of possible forecast outcomes that an ensemble forecast can provide. Ensemble clustering could be a solution to this problem as it can reduce a large ensemble forecast down to the most prevalent forecast scenarios. Forecasters can then quickly view these ensemble clusters to better understand and communicate forecast uncertainty and the range of possible forecast outcomes. The ensemble clustering tool developed at WPC is a variation of fuzzy clustering where operationally available ensemble members with similar 500-hPa geopotential height forecasts are grouped into four clusters. A representative case from 15 February 2021 is presented to demonstrate the clustering methodology and the overall utility of this new ensemble clustering tool. Cumulative verification statistics show that one of the four forecast scenarios identified by this ensemble clustering tool routinely outperforms all the available ensemble mean and deterministic forecasts.

Significance Statement

Ensemble forecasts could be used more effectively in medium-range (3–7 day) forecasting. Currently, the onus is put on forecasters to view and synthesize all of the data contained in an ensemble forecast. This is a task they often do not have time to adequately execute. This work proposes a solution to this problem. An automated tool was developed that would split the available ensemble members into four groups of broadly similar members. These groups were presented to forecasters as four potential forecast outcomes. Forecasters felt this tool helped them to better incorporate ensemble forecasts into their forecast process. Verification shows that presenting ensemble forecasts in this manner is an improvement on currently used ensemble forecast visualization techniques.
Low Self-Control, Peer Risk Factors, and Adolescent Vaping Activity
Authors: Boccio Cashen M.
Published: March 2023

Recent research has identified several risk factors for adolescent vaping. However, limited research has directly explored how low self-control and peer vaping activity are related to adolescent vaping. This study addresses these gaps in the literature by examining relationships between low self-control, peer risk factors for vaping, and adolescent nicotine vaping using a sample of Florida adolescents collected in 2019. In addition, this study examines whether peer risk factors moderate the relationship between low self-control and nicotine vaping. The findings suggest that low self-control and peer nicotine vaping are linked with adolescent nicotine vaping. The findings also provide evidence that peer risk factors may moderate the relationship between low self-control and adolescent nicotine vaping.
Capturing the Growth of Chinese Investment in India
Authors: Choudhury Rahul Nath
Published: March 2023

Chinese foreign direct investment inflows in India increased from just US $1 million in 2010 to the US $173 million in 2019, while the total private equity investment was US $3,423 million in the same period. Chinese companies emerged as majority shareholders in several Indian start-ups, particularly in the technology sector. In contrast to this economic development, there has been a constant clash among the borders, noticeably in the Dokhlam and Galwan valleys with a few other minor clashes in different areas. Both nations are experiencing a booming economic alliance and shrinking political and diplomatic relations at the same time. In this background, the current article attempts to explore the key factors influencing the Chinese to invest in India. This article also attempts to analyse the nature of Chinese investment and explain why many countries look at Chinese investment with suspicion. Applying the regression model, the study finds that various policy variables played a significant role in attracting Chinese investors to India.

Evaluating the Reasons for India’s Withdrawal from RCEP: A General Equilibrium Analysis
Authors: Sharma Sachin Kumar , Narayanan G. Badri , Dobhal Adeet , Akhter Raihan
Published: March 2023

This study identifies and rationalises some of India’s issues and concerns with the signing of the RCEP. By analysing the existing trade balance, import surge trends, dumping and agricultural sensitivities, among other factors, the study justifies India’s decision to remain outside of this mega-FTA. Further, it predicts the impact of tariff elimination under RCEP on various macroeconomic variables of the RCEP member countries by using the GTAP model under two scenarios: (i) India does not join the RCEP and (ii) India joins the RCEP. Results show that India’s GDP would be adversely affected if it joins this agreement, and its overall trade deficit may further deteriorate after joining the RCEP. In terms of the bilateral trade balance, India’s trade deficit with ASEAN and China will grow steeply if it joins the agreement. The study also finds that an RCEP without India may lose its shine as the GDP of most of the other members of the RCEP would be negatively impacted by India’s decision to stay out.

Task Content and Job Losses in the Great Lockdown
Authors: Petroulakis Filippos
Published: March 2023

The author examines the short-term labor market effects of the COVID-19 pandemic (aka the Great Lockdown recession) in the United States. Findings show that the task content is an important predictor of job losses; jobs with a high non-routine cognitive content are especially well-protected, even if they are not teleworkable. Teleworkability matters more for low-paying jobs. The importance of task content, particularly for non-routine cognitive tasks, is strong even after controlling for demographics and for differential sector and location shocks, while effects persist in the medium run. Jobs subject to higher structural turnover rates were much more likely to be terminated, suggesting that easier-to-replace employees were at a particular disadvantage, even within sectors. At the same time, labor hoarding may occur for more valuable matches. Individuals in low-skilled jobs fared comparatively better in industries with a high share of high-skilled workers, suggesting complementarities across skill types.
Investigation of compression after impact failure in carbon fiber reinforced polymers using acoustic emission
Authors: Biagini Davide , Pascoe John-Alan , Alderliesten René
Published: March 2023

Although several studies have been performed, the compression after impact (CAI) failure of CFRP is still not entirely understood. It is still unclear what sequence of events determines the onset of failure in CAI tests and how the different damage modes are involved in this process. To experimentally investigate this matter, the present work relies on acoustic emission (AE) monitoring and advanced acoustic signal analysis. A series of preliminary tests was conducted to correlate damage modes with recorded acoustic waveforms. Four types of waveforms were separated and associated to different damage modes. Following the preliminary tests, AE was monitored in actual CAI tests. A damage accumulation study was conducted combining three indicators, namely wavelet packet components, sentry function and energy b-value. The results evidence different phases in the damage accumulation process that were not shown in previous literature. In all specimens, the onset of the unstable damage accumulation appeared to be triggered by an intermediate frequency acoustic event associated to a combination of matrix cracking and fiber-matrix debonding, occurring at 80% of failure displacement.
Exploring the Intersection of Drug Addiction and Mental Ill-Health in Scottish Prisons: A Qualitative Study of Incarcerated Men
Authors: Deuchar Ross , Densley James
Published: March 2023

This article presents insights from small-scale qualitative research exploring the intertwining nature of drug addiction and mental ill-health among men in Scottish prisons. Semi-structured interviews were conducted with 24 men in two Scottish prisons. The men’s narratives suggested that increased tension in prison halls had stimulated a huge surge in the use of New Psychoactive Substances (NPS), in turn increasing and deepening existing mental ill-health and violence. They believed health care in the prisons to be of low quality, and that methadone was prescribed as a mechanism for social control. Implications for future policy, practice and research are outlined.
Art for Humanizing Mental Illness When Teaching Diagnosis
Authors: Sabados Diana , Potash Jordan S.
Published: March 2023

Teaching a class that covers psychiatric diagnoses is essential for graduate students in mental health professions both for the purpose of providing informed therapeutic services for their clients who may have been diagnosed with a mental illness, and, increasingly, for the provision of diagnosis as a licensed clinician in the United States. Art therapy educators designed an experiential learning approach rooted in two frameworks that humanize mental illness (Two Continua Model of Mental Health and Mental Illness, Power Threat Meaning) combined with reflective art viewing and making. A cumulative art assignment based on one-canvas painting fosters students’ critical perspectives through four observed patterns: appreciating impact of layering; understanding mental illness through art materials and processes; empathizing through reflecting on one’s own experiences; and recognizing the wholeness of those living with mental illness. The incorporation of response art in the psychopathology class has had the intended dual impact of instilling a humanizing approach to mental illness and fostering self-reflection.
Impact of Socio-demographic Characteristics on Time in Outpatient Cardiology Clinics: A Retrospective Analysis
Authors: McIntyre Daniel , Marschner Simone , Thiagalingam Aravinda , Pryce David , Chow Clara K.
Published: March 2023

Inequitable access to health services influences health outcomes. Some studies have found patients of lower socio-economic status (SES) wait longer for surgery, but little data exist on access to outpatient services. This study analyzed patient-level data from outpatient public cardiology clinics and assessed whether low SES patients spend longer accessing ambulatory services. Retrospective analysis of cardiology clinic encounters across 3 public hospitals between 2014 and 2019 was undertaken. Data were linked to age, gender, Indigenous status, country of birth, language spoken at home, number of comorbidities, and postcode. A cox proportional hazards model was applied adjusting for visit type (new/follow up), clinic, and referral source. Higher hazard ratio (HR) indicates shorter clinic time. Overall, 22 367 patients were included (mean [SD] age 61.4 [15.2], 14 925 (66.7%) male). Only 7823 (35.0%) were born in Australia and 8452 (37.8%) were in the lowest SES quintile. Median total clinic time was 84 min (IQR 58-130). Visit type, clinic, and referral source were associated with clinic time (R2 = 0.23, 0.35, 0.20). After adjusting for these variables, older patients spent longer in clinic (HR 0.94 [0.90-0.97]), though there was no difference according to SES (HR 1.02 [0.99-1.06]) or other variables of interest. Time spent attending an outpatient clinic is substantial, amplifying an already significant time burden faced by patients with chronic health conditions. SES was not associated with longer clinic time in our analysis. Time spent in clinics could be used more productively to optimize care, improve health outcomes and patient experience.
Shared Festival Tourism Experiences: The Power and Purpose of Remembering Together
Authors: Wood Emma Harriet , Kinnunen Maarit , Moss Jonathan , Li Yanning
Published: March 2023

Although there is much discussion of what makes travel experiences memorable there is less on how remembering those experiences together then makes us feel and act. This empirical paper builds upon recent conceptual work in shared emotional memory, and explores the processes through which memories are negotiated and how these then affect our attitudes and behavioral intentions. Using an innovative qualitative methodology, we analyze individual and shared memories from six pairs of festival tourists. The findings highlight how wellbeing increases, through a shared reality and sense of belonging, as we negotiate an agreed memory of a past experience. The agreed memory is formed through negotiation, attunement, and emotional synchrony. This desire to agree and the wellbeing benefits that accrue strongly influence attitudes, behavioral intentions, and word-of-mouth. There are important implications for tourism practitioners in the design of experiences and in post-trip marketing activities informed by and influencing consumer memory sharing.
“Water Pays for Water”: Sonora, An Affluent of National Privatization
Authors: Ibarra Fernanda , Centeno Ramón I.
Published: March 2023

A status quo has been structured in Mexico that prioritizes the commercial value of water over its socio-environmental value. Sonora is a typical case of the transfer of a common good to the private sphere. The communities historically linked to the two major affluents in the region, the Río Yaqui and the Río Sonora, have experienced this trend firsthand. There, as in the rest of Mexico, a water market has emerged that has led to de facto privatization benefiting the bourgeoisie.

En México se ha estructurado un status quo que prioriza el valor comercial del agua sobre su socioambiental. Sonora es un caso típico de transferencia de un bien común a la esfera privada. Las comunidades históricamente vinculadas a los dos principales afluentes de la región, el Río Yaqui y el Río Sonora, han experimentado esta tendencia de primera mano. Allí, como en otras partes de México, ha surgido un mercado del agua que ha llevado a una privatización de facto que beneficia a la burguesía.
Academic resilience and test anxiety: The moderating role of achievement goals
Authors: Lim May Li , Chue Kah Loong
Published: March 2023

The present study examined the associations of academic resilience and achievement goals with test anxiety, and the moderating role of achievement goals in the relation between academic resilience and test anxiety among 1632 secondary one students from eight secondary schools in Singapore. Results showed that students who reported lower levels of academic resilience also reported higher levels of cognitive test anxiety, and those who reported higher levels of avoidance-goal endorsement reported higher levels of cognitive test anxiety. Importantly, the relationship between academic resilience and test anxiety was moderated by avoidance-based goals endorsement level. Specifically, this relationship was stronger for those who endorsed higher levels of avoidance-based goals. Approach-based achievement goals did not significantly interact with academic resilience to influence test anxiety. Implications of the findings are discussed.
Nasal Acinic Cell Carcinoma Misdiagnosed as Hemangioma of the Nasal Septum
Authors: Liu Yanan , Peng CongLi , Long Ping
Published: March 2023

Acinic cell carcinoma (AciCC) is a low-grade, slow-growing malignant tumor that commonly originates from the parotid gland and occasionally from the minor gland of the oral cavity, but rarely from the nasal cavity. Here, we present a 57-year-old woman who presented with an 8-month history of obstruction and epistaxis of the right nasal cavity. Rhinoscopy revealed a reddish-gray fleshy mass with tiny blood vessels on the surface blocking the right postnaris. Computed tomography showed a 3 × 2 cm2 well-demarcated tumor filling the right nasal common meatus with a clear boundary. There were no signs of local bone erosion in the bony window. Magnetic resonance imaging revealed abnormal signals in the nasal meatus with iso-intensity in the T1W1 sequence with homogeneous enhancement. We diagnosed it as a right nasal hemangioma, and the patient underwent endoscopic resection. However, histopathological evaluation of the surgical specimen confirmed a primary AciCC. The patient refused further radical surgery and instead underwent adjuvant radiotherapy. There was no clinical evidence of recurrence for 2 years, and the patient has returned for follow-up yearly. We discuss the clinical nature of sinonasal AciCC and the treatment of this rare condition.
Disablement in figure skating: Media, celebrity, spectacle
Authors: Jerreat-Poole Adan
Published: March 2023

Blood on the ice. Cheers when the injured athlete stands and limps off the field. Comebacks, backflips, and back injuries. Celebrity athletes are punished and rewarded for their abilities, including their ability to perform while injured or work through pain. Injuries, illness, disablement, and even death are not uncommon in celebrity culture broadly and the field of competitive sports more specifically. While critical disability studies often attends to disabled celebrities, less research and critical attention has been paid to the disablement of celebrity and the expectation and performance of injury or illness understood through the lens of ablenationalism. Focusing on international figure skating and the 2022 Winter Olympics, this paper offers a supercripping of athletic celebrity by interrogating how gender, race, age, and nationality impact a global audience’s view of vulnerability, risk, and harm. Analyzing media coverage of the event alongside popular discourse uncovers the impact of nationalism, white supremacy, and patriarchy on sports narratives and celebrity cultures of debilitation and disablement.
Reorienting new state capitalism to food and agriculture
Authors: Werner Marion
Published: March 2023

Scholarship on global agri-food regulation would contribute much to new state capitalism debates, which to date largely ignore this field. Contradictions within the global arrangement of corporations, international agencies, national governments and trade architecture governing agriculture in the 1990s set the stage for more robust state roles post-2008. Food price volatility catalyzed neomercantilist policies while, paradoxically, deepening global market relations. States' on-going interventions to manage repriced food offer crucial windows into this paradox of new state capitalism, while centering socioecological dimensions that remain peripheral to new state capitalism debates.
Humility, Fear, and the Relationship between the Gifts and Infused Virtues in Thomas Aquinas
Authors: Eitel Adam
Published: March 2023

In the Secunda secundae of his masterwork, the Summa Theologiae, Thomas Aquinas contends that reverence (an affection elicited by the gift of fear) is both the principle and cause of humility (an infused moral virtue). He suggests also that the relationship between fear and humility is emblematic of the relationship between the gifts of the Holy Spirit and infused virtues as such. This article examines these claims and explores their implications for understanding the contribution of the gifts to the infused virtues’ growth: as the theological virtues grow, the infused moral and intellectual virtues grow with them; yet this happens by the intermediate growth of the gifts. Although uncharted within the landscape of contemporary Aquinas studies, these claims are plainly attested in the Summa and corroborated by the Literal Exposition of Job and the Commentary on John.
A new method for reciprocating compressor fault diagnosis based on indicator diagram feature extraction
Authors: Wu Weifeng , Li Chengyi , Zhu Zhongqing , Li Xiaoran , Zhang Yin , Zhang Jing , Yang Yifan , Yu Xiaoling , Wang Bingsheng
Published: March 2023

The damage of vulnerable components inside the cylinder of reciprocating compressor, including the valve, piston ring, packing and piston ring, will cause the unexpected shutdown of the compressor unit. The indicator diagram which reflects the thermodynamic process in the cylinder is suitable for fault diagnosis of vulnerable components. However, most of the published fault diagnosis methods based on indicator diagram are aimed at the fault diagnosis of gas valve. In addition, the extracted features lack physical meaning in most fault diagnosis methods using machine learning algorithm, which is not conducive to be widely applied in practical engineering. In this study, features with definite physical meaning, including average suction pressure, average discharge pressure, area of indicator diagram and centroid coordinates of indicator diagram, are extracted from indicator diagram, and the threshold database of features under normal states and various fault states is established according to the contrast experiment. The results of the experiment show that the thresholds of the extracted parameters are obviously different under normal states and various fault states. During fault diagnosis, several groups of indicator diagrams of the compressor to be diagnosed are collected at first. After feature extraction, the extracted features are compared with the thresholds under different compressor states to obtain the average numbers of features within the threshold range under different compressor states to determine the compressor states. The accuracy of the method for judging whether the compressor is faulty or normal could reach 98.3%. Furthermore, the accuracy of identifying individual faulty components and multiple faulty components could reach 86.86%. The reason for the low overall diagnostic accuracy is that certain faults have similar effects on the features extracted from indicator diagram. The proposed method is believed as an excellent fault diagnosis method for the vulnerable components inside the cylinder of reciprocating compressor.
Remnant peat deposit provides clues to the inundated cultural landscapes of Kepa Kurl, southwestern Australia

Published: March 2023

In early 2021 several tree stumps embedded in a remnant peat deposit were found in the intertidal zone of Wharton Beach, southwestern Australia by Esperance Tjaltjraak Rangers. Attempts were made to identify the tree using both dendrochronological and anthracological methods but were limited by the lack of reference information from tree species in the southwestern Australia. Radiocarbon dates from one stump indicates the tree lived for approximately 200 years, growing into the peaty sediments sometime before ca. 7340 cal yrs BP and died directly or indirectly as a result of marine transgression. The peat deposit is dated to 7608–7429 cal yrs BP but its exposed seaward edge was unconformably underlain by younger sand, dated by OSL to around 3550 years, which may have intruded as a result of a storm event. An OSL age of 12,600 years was obtained from the base of a laminated dune sequence behind the exposed peat deposit, and is significant given a similar age for a previously documented infant burial site in the area. Together these records provide a rare insight into the former wetland landscape and a cultural and scientific link to the drowned coastal plain. A need for more integrative research along this cultural corridor is clear but this preliminary study has demonstrated the value of combining Cultural Knowledge Systems and Western Science, for Tjaltjraak Healthy Country Program and analogous Aboriginal ‘caring for country’ programmes throughout Australia.
An ecological approach to understanding and addressing health inequities of systemic lupus erythematosus

Published: March 2023

Systemic Lupus Erythematosus (SLE) is a complex chronic autoimmune disease disproportionally afflicting women and, in particular, American Indian/Alaska Native, Black, and Hispanic women. These groups of women have significantly worse SLE-related health outcomes which are partially attributable to their exposure to marginalizing and interconnecting social issues like racism, sexism, economic inequality, and more. Although these groups of women have higher rates of SLE and though it is well known that they are at risk of exposure to marginalizing social phenomena, relatively little SLE literature explicitly links and addresses the relationship between marginalizing social issues and poor SLE-health outcomes among these women. Therefore, we developed a community-engaged partnership with two childhood-SLE diagnosed women of color to identify their perspectives on which systemic issues impacted on their SLE health-related outcomes. Afterward, we used Cochrane guidelines to conduct a rapid review associated with these identified issues and original SLE research. Then, we adapted an ecological model to illustrate the connection between systems issues and SLE health outcomes. Finally, we provided recommendations for ways to research and clinically mitigate SLE health inequities.
Hierarchical tendencies, functional specializations, and (in)stability across European banking centers
Authors: Musschoot Jan , Derudder Ben , Dörry Sabine
Published: March 2023

Drawing on conceptual research exploring how evolving geographies of finance inform urban and regional change, we examine the size and functional scope of the presence of leading global banks across functional urban areas in Europe. Based on data for 100 major global banks, we find that their overall presence is proportional to (the square root of) the national gross domestic product. London and Luxembourg host far more banks than can be explained by their national gross domestic product, which can be traced back to their export of banking services. We also analyze the geographies of specialized banking services per city. Corporate and investment banking are mainly explained by national gross domestic product, with London emerging as the most prominent center. Private banking and securities services, in turn, are largely independent of national gross domestic product and rely on the importance of small and specialized economies such as Luxembourg and St Helier (Jersey). The stability of Europe’s banking centers is underpinned by their role as the national banking center and/or their specialization in international banking services, as well as manifested in specialized subnetworks of financial centers.
Socio-Managerial Framework of Health Governance: Empirical Evidence from India’s National Sanitation Program (SBM-G)
Authors: Nanda Satyajeet , Warrier Uma
Published: March 2023

Given that citizen participation is considered the main pillar of ‘Development’, the political economy behind its practice (behaviour and utilisation) remains a question. To disentangle the complex web of relationships that the governance shares with the citizens’ interface, it would be worthwhile to examine the whole phenomenon at the grass root level. A review of issues surrounding democracy has led different schools of thought to realise the need for adopting a holistic development approach for ensuring citizens’ participation in development processes. One such school believes that it is only through addressing governance bottlenecks and ensuring spaces for participation in policy design, programme formulation and implementation supplemented with proper monitoring, that ‘real’ development can be achieved. It is also universally accepted that governance is an enabler for socio-economic transformation and this can help in the improvement of lives through the eradication of structural inequality. Hence, strengthening the local governments is critical for ensuring citizen empowerment, civic participation and better service delivery. Furthermore, governance is measurable and can be monitored; thus can ensure a measurable implementation, accountability and monitoring framework (Global Thematic Consultation on Governance and the Post-2015 Development Framework, 2013). Against these backdrops, the current study endeavours to unearth plausible factors influencing the health behaviour of rural people examining a case of India’s National Sanitation Program—Swachh Bharat Mission in Odisha villages. Analysis of primary data collected from six districts across different regions of the Odisha state shows that various managerial, governance and social factors have a significant effect on the health behaviour of people and present more insightful results.
Anatomical features of plantar fasciitis in various age cohorts: Based on magnetic resonance imaging
Authors: Zhang Lei , Cai Mingyang , Gan Yiwen , Xia Zhangrong , Xiong Jixiang , Sun Xinghao , Yang Peixin , Tang Huining , Wang Guoyou
Published: March 2023

Background

Due to the lack of further studies on the influence of age factors on plantar fasciitis, this study evaluates the characteristic observation points of magnetic resonance imaging in various age cohorts of patients with plantar fasciitis to help diagnosis.

Methods

A retrospective analysis of 160 cases of plantar fasciitis patients and normal subjects (who have the disease unrelated to plantar fasciitis) who have undergone an MRI examination in our institution. The two groups were separately divided into young adult subjects (36 to 44 years old), middle age adult subjects (45 to 59 years old), and older adult subjects (60 to 79 years old). Data was gathered regarding plantar fascia thickness, the coronal length of the plantar fascia at the calcaneal origin, the signal intensity of plantar fascia and surrounding structures, and the presence or absence of plantar calcaneal spurs, all of which were assessed objectively by the investigators.

Results

There were statistical differences in the thickness of plantar fascia between two groups of three age cohorts (Older adult patients: 0.59 ± 0.09 cm; Middle age adult patients: 0.49 ± 0.09 cm; Young adult patients: 0.47 ± 0.05 cm) (all p < 0.001). In addition, there were also statistical differences in the high signal intensity changes of the plantar fascia and surrounding soft tissues between two groups of three age cohorts (all p < 0.001). In older adult plantar fasciitis patients, with regard to plantar calcaneal spur discovery, there was a statistical difference between the two groups (Chi-square = 12.799. df = 1. p < 0.001).

Conclusion

In plantar fasciitis cases where a diagnosis is difficult, abnormalities in the soft tissue surrounding the plantar fascia in patients of low age are noteworthy. In older adult patients, the discovery of plantar calcaneal spurs with abnormal thickening of plantar fascia deserves attention, and abnormal MRI findings are more manifest. But the final diagnosis should be based on the medical history.

Teachers’ Vocabulary Talk in Early-Elementary Science Instruction
Authors: Anderson Blythe E. , Wright Tanya S. , Gotwals Amelia Wenk
Published: March 2023

The purpose of this study was to examine the ways in which teachers use language to promote vocabulary development (i.e., vocabulary talk moves) during science instruction in early-elementary classrooms. Twenty-four total science lessons were recorded by eight teachers, providing 894.27 min of observational data across three timepoints. Discourse analysis was used to identify specific research-aligned vocabulary talk moves. Findings revealed that the cohort of teachers used considerably more moves for building students’ knowledge of word meanings than for building students’ awareness of words and word learning or for interesting students in words and word learning. Likewise, the cohort used more authoritative moves (teacher telling) than dialogic moves (inviting student exploration and engagement). This study contributes to the field's understanding of the ways that science instruction supports literacy learning and literacy instruction supports science learning in the early-elementary grades. The findings from this study have implications for teacher professional development and policy.
Tribological roles of MoS2 and PTFE nano oils at the rolling/sliding point contacts: Conventional versus textured contacts
Authors: Chaudhary Rameshwar , Pandey RK , Mazumdar SK
Published: March 2023

Nanolubricants and surface textures have evidenced the ability to improve the tribo-performances of concentrated contacts. Motivated by this finding as reported in the literature, in the present work, the synergistic uses of laser-created surface textures and nanolubricants have been employed to explore and improve the tribological behaviours of moderately loaded ( PH = 0.5 and 0.8 GPa) point contacts operating mainly in mixed and elastohydrodynamic lubrication regimes. MoS2 and polytetrafluoroethylene (PTFE) nanoparticles based on two nanolubricants were prepared in the laboratory to lubricate the rolling/sliding conventional and textured point contacts. Two sets of contacts (grounded discs versus lapped balls and grounded textured discs versus lapped balls) have been employed to create the geometric configuration of conventional and textured concentrated point contacts. Based on the experimental results found herein, the friction coefficient with the textured contacts reduced by 64% in the presence of MoS2-based nanolubricant as compared to the conventional point contact lubricated with the base oil; however, in the presence of polytetrafluoroethylene-based nanolubricant, this reduction has been recorded by 56%. The textured surface involving a small dimple size yielded better results than the relatively large size. Worn surfaces have been investigated and analysed using optical and scanning electron microscopy/energy dispersive X-ray spectroscopy micro-images. Moreover, certain surface studies using atomic force microscope have also been conducted to understand the surface topography and associated wear mechanisms.
Factors of relationship satisfaction for autistic and non-autistic partners in long-term relationships
Authors: Yew Rui Ying , Hooley Merrilyn , Stokes Mark A
Published: March 2023

Autistic individuals have reported lower satisfaction in their romantic relationships compared to non-autistic individuals. Previous research on the factors that contribute to relationship satisfaction within autism has focused on the characteristics of autistic participants as barriers to relationship satisfaction, while overlooking the role of their partners. This study investigated a range of factors and their association with long-term relationship satisfaction for 95 autistic individuals and 65 non-autistic individuals in current or previous long-term relationships with autistic individuals. Participants completed an online survey, including questionnaires measuring autistic traits, the Big Five personality traits, social loneliness, partner responsiveness, sexual satisfaction and relationship satisfaction. Partner responsiveness significantly predicted relationship satisfaction for both autistic and non-autistic partners. The findings suggest that to enhance relationship satisfaction, service providers working with couples involving an autistic individual would improve the relationship by focusing on assisting their clients to identify each other’s needs and how best to meet them.

Lay abstract

Previous research has found that autistic people report lower satisfaction in their romantic relationships compared to non-autistic people. However, the majority of this research has focused on autistic traits as barriers to relationship satisfaction, while overlooking the role of their partners in these relationships. Our study explored a range of factors in both autistic people and non-autistic partners of autistic people and how they may be linked to long-term relationship satisfaction. These factors included social and communication skills, personality traits, social loneliness, partner responsiveness, and sexual satisfaction. We found that partner responsiveness was a strong predictor of relationship satisfaction for both autistic and non-autistic partners, suggesting that rather than focusing intervention solely on the autistic person, the role of their partner should also be considered. Service providers who work with couples involving an autistic person to enhance their relationship satisfaction could focus on assisting their clients to identify each other’s needs and how best to meet them.
Mozambican “tolerance” toward homosexuality: Lusotropicalist myth and homonationalism
Authors: Miguel Francisco PV
Published: March 2023

In this article, the result of ethnographic research on the LGBT community over the last five years in Mozambique, I will deal theoretically with a hegemonic elite discourse alleging tolerance of homosexuality in this country. I will review previous scholarly works on this theme and analyze the recurrence of this discourse among certain elite groups, such as local activists, journalists, and politicians. I conclude that this discourse is reminiscent of the Lusotropicalist myth transformed into a new kind of homonationalism and that it explicitly reverberates in the current political strategies of LGBT activism in Mozambique.
Vibration isolation by a periodic beam with embedded acoustic black holes based on a hybrid dynamics method

Published: March 2023

The acoustic black hole (ABH) has been proved to reduce broadband vibration response in beams and plates. While the traditional analytical and semi-analytical methods can only deal with the response of simple ABH structures; for complex ABH structures, the numerical methods such as the finite element method (FEM) have to be resorted and these methods are too often time-consuming. In this work, the vibration isolation by a beam structure embedded with periodic embedded symmetric ABHs is investigated. The vibration transmission of a single embedded symmetric ABH beam unit is first studied by the Riccati transfer matrix method (RTMM). A comparative analysis of the convergence speed and the computation efficiency of the unit by the RTMM and the FEM demonstrates the computation time using the RTMM increases linearly with the number of segments while that using the FEM increases exponentially and quickly exceeds the former as the number of segments increases. The computation time is consistent with the computational complexity associated with their respective algorithms. A hybrid dynamics method (HDM) is then proposed to derive for the vibration transmission solution of the beam with single and multiple periodically embedded symmetric ABHs. A comparison of the responses with those calculated by the RTMM demonstrates that the proposed HDM provides an efficient tool for solving the vibration response of the finite beam with periodic embedded ABHs, leading to much improved computational efficiency with ensured numerical stability and accuracy. This advantage in computation efficiency becomes even more obvious for larger structures when the number of the ABH units increased considerably. The proposed hybrid dynamic approach provides a basis for solving the vibration transmission/isolation problems of more complex ABH structures.
