Investigation of electrostatically tunable adhesion and instability of flying head slider
Authors: Zhang Fan , Wang Yu , Hu Yueqiang , Zhang Mingquan , Li Baotong 
Published: August 2023

AbstractThe interfacial adhesion between microstructures is inevitable in a micro-electro-mechanical system (e.g., hard disk drive (HDD)), which may lead to complicated microtribodynamics problems. This research has investigated the effect of surface potential on the interfacial adhesion and microtribodynamics of the head–disk interface (HDI) in an HDD. A dynamic continuum surface force model, where the electrowetting is considered, is proposed to evaluate the interfacial interaction, and then employed into a two-degree-of-freedom (2DOF) model to theoretically analyze the potential influence mechanism on the microtribodynamics. The results confirm that the elimination of potential can effectively repress the adhesion retention, which is further proved by the measured slider response with a laser Doppler vibrometer (LDV). Moreover, the effect of the potential on the adhesion-induced instability is also analyzed through the phase portrait. It tells that the critical stable flying height can be lowered with the elimination of potential.
Cybersecurity knowledge graphs construction and quality assessment

Published: August 2023

AbstractCyber-attack activities are complex and ever-changing, posing severe challenges to cybersecurity personnel. Introducing knowledge graphs into the field of cybersecurity helps depict the intricate cybersecurity landscape and provides technical support for threat identification and situational awareness. However, during the process of constructing knowledge graphs, inevitable noise and conflicts may be introduced, leading to misleading inferences and decisions. This paper aims to address the issues of constructing and assessing the quality of cybersecurity knowledge graphs. We manually constructed a dataset of cybersecurity knowledge graphs (CS13K) and expanded the existing cybersecurity ontology, building a more versatile ontology applicable to existing data features. Building upon this, we utilized Neo4j to construct the cybersecurity knowledge graph. Furthermore, we propose an AttTucker model, based on Transformer, for assessing the quality of knowledge graphs. By employing numerous self-attention heads, this model captures latent information among entities and relations. While reducing the dimensionality of knowledge embeddings, the model achieves evaluation results comparable to high-dimensional embeddings. Finally, we incorporate the path-level information between entities in the knowledge graph into the evaluation of knowledge graph quality based on the AttTucker model. Experimental analysis on both generic datasets and cybersecurity datasets demonstrates that our model significantly improves F1 value and accuracy in knowledge graph quality assessment tasks, outperforming other models.
Social Networking Site Use, Self-Compassion, and Attitudes Towards Cosmetic Surgery in Young Australian Women
Authors: Conboy Lauren , Mingoia John 
Published: August 2023

AbstractThis study aimed to explore the relationship of total social networking site (SNS) use and attitudes towards cosmetic surgery in young Australian women through the moderating role of self-compassion. Recent research has identified the potentially protective factor of self-compassion in body image concerns; however, few researchers have further explored the components of self-compassion in relation to SNS use. As such, the positive (self-kindness, common humanity, and mindfulness) and negative (self-judgement, isolation, and over-identification) components of self-compassion were further investigated. The present study utilised a cross-sectional correlational design with self-reported data to determine if self-compassion moderated the relationship between SNS use and attitudes towards cosmetic surgery. A sample of 238 young Australian women, aged 18 to 29 (M = 22.1, SD = 2.9), were recruited. Participants completed an online questionnaire measuring total daily SNS use, self-compassion, and attitudes towards cosmetic surgery. SNS use was significantly negatively correlated with self-compassion and positively correlated with cosmetic surgery. Self-compassion was significantly negatively correlated with attitudes towards cosmetic surgery; however, contrary to expected, self-compassion was not a significant moderator of SNS use and attitudes towards cosmetic surgery. The components of self-compassion were further explored to better understand this relationship, with over-identification significantly predicting more positive attitudes towards cosmetic surgery. The present study highlights the relationship between SNS use and attitudes towards cosmetic surgery. As over-identification relates to ruminating in feelings of discomfort, the results may suggest that SNS users who are more likely to fixate on their appearance dissatisfaction are more likely to have positive attitudes towards cosmetic surgery. Given the popularity of SNS use, this media may pose as an opportune platform to disseminate appearance modification interventions for young adult women. Future research that is causational in nature may be able to confirm these suggested implications.
Is the Only Rational Personality that of the Psychopath? Homo Economicus as The Most Serious Threat to Business Ethics Globally
Authors: Boddy Clive R. 
Published: August 2023

AbstractThe current paper explores the rationality and associated non-emotionality of the psychopathic mind. This was undertaken because psychopaths in the corporate sphere (corporate psychopaths) have been identified as possessing the ability to rise to senior leadership positions within organisations from where they can wield enormous power over their colleagues, organisation and society. When in leadership, the psychopathic create emotional turbulence among their colleagues and subordinates, resulting in an extreme workplace environment. Nonetheless, findings as to the rationality of the psychopathic, include that psychopaths do embody the characteristics of economic rationality and may be the only rational human or ‘homo economicus’ that exists. Taken together with their total immorality and lack of all integrity this makes them the most serious threat to business ethics globally and a threat to the coherence of human society. These findings are important because such people care nothing for the future of humanity and their rationality is dedicated towards personal, short-term gratification. Potentially dire implications for humanity, organisations and society are drawn from this.
An Historical Archaeology of Labor in Convict Australia: A Framework for Engagement
Authors: Gibbs Martin , Tuffin Richard , Roe David 
Published: August 2023

AbstractBetween 1788 and 1868 Britain transported some 171,000 male and female convicted felons to Australia, in the process establishing the foundation European population and instituting a process of invasion and colonization. The convict “system” remains a signature theme in Australian historical and archaeological research, contributing to a multitude of areas of investigation: punishment and reform, colonialism, and colonization process, as well as social aspiration and cultural transformation. This article provides an overview of the history, organization, and physical structure of the system. It then describes recent efforts to reunify the trajectories of archaeology, history, and historical criminology through cross-disciplinary projects, questions, and themes. It includes a description of the authors’ Landscapes of Production and Punishment research framework, which views the organization and administration of the convict system, as well as the shifting balances between punishment and reform, through a labor-systems analysis. This line of inquiry broadens the scope of archaeological interest away from its focus on prisons and institutional sites. It embraces a wider range of labor settings and products, including the dispersal of convicts across urban and frontier areas, and the operational logic behind the system. It also views the convicts both as individuals and a labor force, and the raw materials, roads, buildings, and other items they extracted, constructed, or manufactured equally as “products” of the regime.

Exploring Primary School Staff Responses to Student Reports of Bullying in Australia: A Qualitative Study
Authors: Gizzarelli Emily , Burns Sharyn , Francis Jacinta 
Published: August 2023

AbstractBullying behaviour often increases in late childhood and peaks in early adolescence. While interventions to address bullying behaviour typically encourage students to report bullying incidents to school staff, students are often reluctant to report incidents for fear it will worsen their situation or because they lack confidence in a staff members’ ability to intervene effectively. This study explores school staff responses to student reports of bullying behaviour. School staff were recruited from Catholic and Independent schools in Perth, Western Australia. Semi-structured interviews were conducted with school staff (n = 19) working with students in grades four to six (approximately 8–12 years). A thematic analysis of the data was undertaken with the assistance of qualitative data analysis software NVivo. Staff reported a variety of responses to student reports of bullying incidents. Responses involved bullying targets, bullying perpetrators and the school community. School and individual factors found to influence staff responses included life experiences, adequate time to deal with bullying and the influence of colleagues. Suggested strategies to improve staff responses were clear school policies and procedures, scheduled times to deal with student reports, databases to record bullying incidents and professional development for school staff.
[Re]Imagining Indigenous Educational Design: A Conceptual Manifesto to Grow Disruptive Indigenous Digital Activists
Authors: Meston Troy 
Published: August 2023

AbstractThe ubiquity of digital technologies and the harvesting of individual data has modified global societies, reinforcing systems of oppression. While a contemporary phenomenon, the convergence of technology and human subjugation is historical, with links to the racialised reproduction of settler-colonialism. Australia, a settler-colonial state, has escalated the prioritisation of digital competitiveness with a recent policy directed at stimulating infrastructure and research-industry-government partnerships. Strategically, Indigenous communities remain constrained, where the ubiquity of technology and the escalation of digital competitiveness compounds the socio-economic impacts of continuing colonisation. Offline, Indigenous communities continue to face rigid political constraint that limits online access and denies opportunities for their people to live anchored to ancestral lands, seas, languages, and knowledge systems. Given the rapid advance of digital disruption, the inability to limit racialised socio-technical systems, or compete at parity in cyberspace, suppresses Indigenous digital activism, governance, and entrepreneurialism. This conceptual paper (part manifesto, part vision statement) offers initial thoughts intended to stimulate further research on twenty-first-century Indigenous educational design. Central to future design considerations is the search for pragmatic solutions capable of overcoming the racialised challenges limiting the collective development of digital activists essential for Indigenous nation-building. In [re]imagining an alternate digital educational agenda, Indigenous communities must collectively advance strategies that deliberately shift away from Australian schools toward local community digital learning hubs.

AbstractThe structural reconstruction mechanism of lignin and cellulose-derived biochars during direct graphitization under ultra-high temperatures was intensively investigated. It was demonstrated that cellulose-derived char was almost composed of carbon microcrystallites, whereas lignin-derived char reserved some of its skeleton structures, and such structural difference played a vital role in the morphology of formed graphitic layers. The results illustrated that the graphitized lignin-derived sample under 2800 ℃ had graphitic degree of 89.53%, interlayer spacing of 0.3363 nm and electronic conductivity of 104.6 S cm−1, while cellulose-derived sample had graphitic degree of 76.74%, layer distance of 0.3374 nm, and electronic conductivity of only 48.8 S cm−1. Combined with the results of structural analysis of the chars derived from lignin and cellulose, it was inferred that the stable and aromatic ring containing skeleton structure in lignin was beneficial to the ring-enlarging reconstruction and the formation of large areas of continuous graphitic layers during graphitizing process, leading to high electronic conductivity. Meanwhile, the interwoven microcrystallites in cellulose-derived char strongly restricted the expanding of continuous lamellar graphitic areas even at such ultra-high temperature, causing the formation of turbostratic structure with numerous structural defects as well, and finally resulting in relatively lower electronic conductivity. This work is expected to provide theoretical guidance for preparing high-performance functional carbon materials from lignocellulosic biomass.

AbstractThe blue antelope or bluebuck (Hippotragus leucophaeus) is an extinct species of antelope that lived in South Africa until ca. 1799–1800. Disappearing only 34 years after it was described, it was the first large African mammal species to have become extinct in recent times. Therefore, current scientific knowledge of the blue antelope is limited to museum specimens. However, these are extremely rare and further complicated by uncertainties surrounding their taxonomic status due to morphological similarity with the closely related extant roan antelope (Hippotragus equinus) and sable antelope (Hippotragus niger). A previous study found that only four (out of ten) genetically analysed historical museum specimens could be confirmed as Hippotragus leucophaeus. Here, we analyse a further five potential blue antelope specimens, two of which had been morphologically identified as blue antelope (one from the Natural History Museum (NHM) in London and one from National Museums Scotland in Edinburgh), plus an additional three specimens identified here as candidate blue antelope specimens (from the NHM). We find that only one of the five specimens can be genetically validated as Hippotragus leucophaeus, whereas the other four specimens were identified as H. equinus. Furthermore, using hybridisation capture, we generated two complete mitochondrial genomes for blue antelope specimens that were formerly known only from partial mitochondrial genomes. The diversity analyses including all newly generated genomes further confirm that the mitochondrial nucleotide diversity across this species was low.
Towards the global zero poverty agenda: examining the multidimensional poverty situation in South Africa

Published: August 2023

AbstractThe vulnerability of smallholder farmers to multidimensional poverty in the Eastern Cape province of South Africa was assessed, using the Alkire Foster multidimensional poverty index developed by the Oxford Poverty and Human Development Initiative and aligned to the Sustainable Development Goals (SDGs). The findings show that the deprivation indicator ranges from 5 to 90%, revealing that access to a flush toilet facility is an imperative factor towards the households’ standard of living (SDG11). Also, 66% and 55% were deprived of food security (SDG2) and education (SDG4), respectively. The probit analysis result revealed that gender, remittances, crop diversification (CDV), education, seasonal farming and market outlets significantly influence the multidimensional poverty and vulnerability poverty of rural households in the Eastern Cape province of South Africa. For instance, factors such as household size showed that an additional unit increase in the size of a household would result in a 5% increase in the chances of the household’s vulnerability to multidimensional poverty. Likewise the extension contact, a unit increase resulted in 49% in the households’ vulnerability to multidimensional poverty. The study suggests that policies related to improving education, increasing CDV, promoting farmer groups and the effectiveness of extension contact, and increasing market stability for sales of farm products could contribute to reducing the multidimensional poverty level and the vulnerability of households.
Sourcing third party logistics service providers based on environmental, social and corporate governance: a case study
Authors: Moreira Otacilio Jose , Rodrigues Maria Carolina Martins 
Published: August 2023

AbstractThe acronym ESG, environmental, social and governance, emerges as a strong trend in the era of the circular economy and stands out as a need for companies to respond to the segment in which they operate. Although most studies have been done in the past, they did not address ESG criteria to ensure operator exemption for logistics providers. Further research on the application of realistic circular economy techniques is recommended. Therefore, strategic sourcing, based on multicriteria decision analysis (MDA), considering parameters such as economic, technical, and environmental factors, has created a perfect methodology that considers all these essential requirements, revealing an excellent way to outsource logistics service providers (LSPs). The article aims to prove MDA’s effectiveness awarding the best LSP through predefined dimensions involving human resources, risk management, environmental and other social aspects, indicating dedication and commitment to social environmental issues and corporate governance during a procurement’s strategic sourcing in a Brazilian pharmaceutical company process. A Literature review supported by a real case study where a multifunctional team from Pharmaceutical and Consultants proved the objective was valid. A secondary objective was demonstrated on how current sustainability challenges can be overcome by the organization and generate value for its stakeholders and society, showing responsibility and commitment to environmental, social, and corporate governance issues. After reviewing all the concepts involved using the literature review, the results were achieved indicating that sourcing process’ case study through MDA validated the effectiveness choosing the 3PL with the best results in ESG. The article deals with a current, relevant, and not very explored topic and may contribute to enhancing the investments of logistics service providers (LSPs) in ESG, mainly those that weren’t awarded at end of the project.
Portable multiscale form measurement technique for structured specular surfaces based on phase measuring deflectometry
Authors: Xu Yongjia , Gao Feng , Yu Yang , Wang Jian , Jiang Xiangqian 
Published: August 2023

AbstractPropelled by the rapidly growing demand for function incorporation and performance improvement, various specular components with complex structured surfaces are broadly applied in numerous optical engineering arenas. Form accuracy of the structured surfaces directly impacts the functioning of the specular components. Because the scales of these structures and/or the importance of their functions are usually designed differently, the structures require different measurement demands in scale, lateral resolution, and accuracy. In this paper, a multiscale form measurement technique is proposed based on triple-sensor phase measuring deflectometry for measuring structured specular surfaces. The proposed technique contains two sub-phase measuring deflectometry(PMD)-systems. Each sub-system works as a single segmentation PMD (SPMD) system and is designed to have different measurement scales, lateral resolutions, and accuracies to meet the measurement demands of the targeted surfaces. Two imaging sensors in the proposed technique cover the measured full-scale surface. The specular surface is separated into several continuous segments through algorithms and the spatial relationship of the continuous segments is established based on absolute depth data calculated through the triangular relationship between the two imaging sensors. The third imaging sensor with a long working distance only captures the field of the small-scale structures and reconstructs the structures based on gradient data to improve the structures’ reconstruction resolution and accuracy. In order to make it suitable for portable and embedded measurement, a compact configuration is explored to reduce system volume. Data fusion techniques are also studied to combine the measurement data of the two sub-systems. Experimental results demonstrate the validity of a portable prototype developed based on the proposed technique by measuring a concave mirror with small-scale structures.
