This study examined the motivational factors influencing African immigrants in New Zealand to become entrepreneurs and the factors that ensured their business success. Data were collected from 117 participants through survey questions employing the Qualtrics platform and its link was sent to participants in the Auckland region. Auckland was decided on for data collection, being the most populated city and the business nerve centre of New Zealand. The research was conducted using a descriptive and quantitative approach. From the analysis, the study found that passion for business entrepreneurship, flexibility, financial independence, generic independence, autonomy, and being one’s own boss are the most highly motivational factors for influencing African immigrants in New Zealand to opt for business ownership. The study also found that the six highest-rated reasons for African immigrants’ entrepreneurial business success in New Zealand were readiness to make sacrifices to succeed, always giving the best in everything that had to be done, the importance of action, a belief that everything is possible if the entrepreneur believes he/she can do it, the challenge of taking on new projects, and learning lessons from past failure. These findings are the most important factors helping African immigrant business owners in New Auckland Zealand to attain entrepreneurial and business success. This research maintains that the results shed light on why African migrants adopt business entrepreneurship and gear themselves up for success in New Zealand.

This work analyses the genetic potential of Stevia rebaudiana beyond its sweetening properties, aiming to reassess its conservation and utilization in breeding programmes. This focus is justified by the growing global demand for natural sweeteners and the challenges posed by extreme weather events and diseases affecting crop yield and quality. The relationship between the species’ genetic diversity and its response to biotic and abiotic stresses is explored, as well as the limitations of current conservation and breeding strategies. Findings reveal underutilized genetic resources, limited integration of genomic tools in breeding efforts and a lack of robust in situ conservation initiatives. Genotypic variability has been observed in response to diseases such as Septoria leaf spot, while abiotic factors, including salinity and drought, can significantly influence steviol glycoside content. It is concluded that an integrated approach, combining dynamic conservation, photoperiod‐informed breeding strategies, improvements in seed viability, omics‐based tools and coherent public policies, is essential to ensure crop resilience and genetic sovereignty, especially in regions of origin such as Paraguay. The sustainable use of Stevia’s genetic diversity could foster more sustainable, healthier and fairer production systems.

Using a behavioural intervention to target nutrition during pregnancy may be key in meeting recommendations for healthy eating. The aim was to assess the use of a short-term dietary intake measurement tool (3-day food intake record) to infer long-term habitual dietary intake during pregnancy (using a short-form FFQ). A convenience sample (n 90) between 12- and 18-weeks’ gestation was recruited from a larger randomised controlled trial for cross-sectional analysis. Participants completed a forty-four-item FFQ and 3-day food intake record. Using the participant food intake record, the investigator blindly completed a second frequency questionnaire. The frequency questionnaires were scored using dietary quality scores (DQS) and compared. Aggregate data were evaluated using a Wilcoxon signed rank test, and individual-level data were evaluated using a Bland–Altman plot. No significant difference was observed in the scores (Z = –1·88, P = 0·06), with small effect size (r= 0·19). The Bland–Altman plot showed that comparing the DQS derived from the two different dietary assessments underestimated scores by a mean difference of 0·4 points (95 % limits of agreement: −3·50 to 4·26). The data points were evenly spread suggesting no systematic variation for over- or underestimation of scores. Minimal difference was observed between the functionality of the two assessment instruments. However, the food intake record can be completed by pregnant individuals to estimate short-term nutrient intake and then scored by the investigator to estimate long-term dietary quality. Combining these two instruments may best capture the most accurate representation of dietary habits over time.

Disasters can have catastrophic effects on people’s physical, mental, and psychosocial status, as well as public health. Many people undoubtedly suffer from short- and long-term disabilities as a result of the disaster once the first shock wears off [1]. Two devastating earthquakes caused extensive damage in southern and central Türkiye and northern and western Syria in February 2023, resulting in thousands of deaths and injuries. It is estimated that approximately 15 million people were affected. Since there is a possibility that people affected by the earthquake will continue their lives with disabilities, it is important to make an early assessment and make preliminary preparations in this respect. With this preparation and rehabilitation carried out in the early period, it is aimed at helping individuals adapt more quickly to both personal and social life and to increase their independence in daily life.

We propose CTREND, a new trend factor for cryptocurrency returns, which aggregates price and volume information across different time horizons. Using data on more than 3,000 coins, we employ machine learning methods to exploit information from various technical indicators. The resulting signal reliably predicts cryptocurrency returns. The effect cannot be subsumed by known factors and remains robust across different subperiods, market states, and alternative research designs. Moreover, it survives the impact of transaction costs and persists in big and liquid coins. Finally, an asset pricing model that incorporates CTREND outperforms competing factor models, providing a superior explanation of cryptocurrency returns.

Historical censuses have often served as valuable sources for understanding the past. Yet, their use as sources about women’s work has been highly debated. This article engages with the continuing debate regarding the reliability and validity of censuses by exploring significant potentials and issues of censuses’ information about women’s work. While recognizing a critical perspective on censuses’ information about women’s work, this article identifies the need for more careful and contextualized readings of censuses. To this end, it presents five novel analytical approaches that aim to enhance readings and interpretations of censuses. The approaches reveal the purposes, focuses, self-reflections, ambiguities, and evolving categorizations of censuses, respectively. Through analysis of Swedish census materials from 1910 to 1940, this article moreover demonstrates that historical census personnel engaged with women’s work in sophisticated ways and that censuses’ representations were complex. The article argues against dismissing censuses outright as a fruitful source about women’s work. Instead, it recommends leveraging their inherent qualities in new and creative ways. Though non-neutral by incorporating and disseminating ideas about gender, censuses can serve as rich historical sources about women’s work and societal roles when approached contextually in various ways. The article advocates for contextualized and historicized approaches to using census data, moving beyond simplistic labels to explore the complexities of these important historical sources.

The offshoring-fuelled growth of the Central and Eastern European business services sector gave rise to shared service centres (SSCs) – quasi-autonomous entities providing routine-intensive tasks for the central organisation. The advent of technologies such as intelligent process automation, robotic process automation, and artificial intelligence jeopardises SSCs’ employment model, necessitating workers’ skills adaptation. The study challenges the deskilling hypothesis and reveals that automation in the Polish SSCs is conducive to upskilling and worker autonomy. Drawing on 31 in-depth interviews, we highlight the negotiated nature of automation processes shaped by interactions between headquarters, SSCs, and their workers. Workers actively participated in automation processes, eliminating the most mundane tasks. This resulted in upskilling, higher job satisfaction, and empowerment. Yet, this phenomenon heavily depends upon the fact that automation is triggered by labour shortages, which limit the expansion of SSCs. This situation encourages companies to leverage the specific expertise entrenched in their existing workforce. The study underscores the importance of fostering employee-driven automation and upskilling initiatives for overall job satisfaction and quality.

The impact of the self-sealing band on interior ballistics is investigated during the gun launching, and a high-precision interior ballistics coupling algorithm that takes leakage into account is proposed. This study focuses on a 65 mm short-barrel, equal-caliber balanced cannon, integrating Abaqus finite element software with an interior ballistics calculation programme. It uses a User-defined AMPlication Load (VUAMP) subroutine to achieve real-time coupling calculations of the chamber pressure and self-sealing band deformation, correcting variations in the chamber pressure. Experimental results show that the coupling algorithm offers the higher precision compared to traditional interior ballistics models and can effectively capture the impact of leakage on the interior ballistics performance. Further research reveals that changes in the charge amount and assembly gap significantly affect the sealing performance of the self-sealing band and the leakage of propellant gases, which in turn influence the chamber pressure and projectile velocity. The high-precision coupling algorithm proposed in this paper provides the effective theoretical support for the design of the self-sealing band and the analysis of cannon performance.

Characterizing the structure and composition of clay minerals on the surface of Mars is important for reconstructing past aqueous processes and environments. Data from the CheMin X-ray diffraction (XRD) instrument on the Mars Science Laboratory Curiosity rover demonstrate a ubiquitous presence of collapsed smectite (basal spacing of 10 Å) in ~3.6-billion-year-old lacustrine mudstone in Gale crater, except for expanded smectite (basal spacing of 13.5 Å) at the base of the stratigraphic section in a location called Yellowknife Bay. Hypotheses to explain expanded smectite include partial chloritization by Mg(OH)2 or solvation-shell H2O molecules associated with interlayer Mg2+. The objective of this work is to test these hypotheses by measuring partially chloritized and Mg-saturated smectite using laboratory instruments that are analogous to those on Mars rovers and orbiters. This work presents Mars-analog XRD, evolved gas analysis (EGA), and visible/shortwave-infrared (VSWIR) data from three smectite standards that were Mg-saturated and partially and fully chloritized with Mg(OH)2. Laboratory data are compared with XRD and EGA data collected from Yellowknife Bay by the Curiosity rover to examine whether the expanded smectite can be explained by partial chloritization and what this implies about the diagenetic history of Gale crater. Spectral signatures of partial chloritization by hydroxy-Mg are investigated that may allow the identification of partially chloritized smectite in Martian VSWIR reflectance spectra collected from orbit or in situ by the SuperCam instrument suite on the Mars 2020 Perseverance rover. Laboratory XRD and EGA data of partially chloritized saponite are consistent with data collected from Curiosity. The presence of partially chloritized (with Mg(OH)2) saponite in Gale crater suggests brief interactions between diagenetic alkaline Mg2+-bearing fluids and some of the mudstone exposed at Yellowknife Bay, but not in other parts of the stratigraphic section. The location of Yellowknife Bay at the base of the stratigraphic section may explain the presence of alkaline Mg2+-bearing fluids here but not in other areas of Gale crater investigated by Curiosity. Early diagenetic fluids may have had a sufficiently long residence time in a closed system to equilibrate with basaltic minerals, creating an elevated pH, whereas diagenetic environments higher in the section may have been in an open system, therefore preventing fluid pH from becoming alkaline.

With China’s economy transitioning into a post-industrial phase focused on knowledge and technology, there has been a notable shift in the patterns of Chinese Outward foreign direct investment (OFDI). This change has led to the emergence of new research perspectives, underscoring the importance of organizing them systematically. To address this, our research presents a thorough analysis of eighty-eight publications examining Chinese OFDI in natural resource-rich (NRR) and technology-intensive (TI) locations across various global regions and countries. Based on the geographical scope and comprehensive coverage of studies published between 1998 and 2023, we summarize the major themes, theories, and methodologies used in this research area. Identifying three elements related to Chinese investment (antecedents and motives, operational strategies, and investment outcomes), we develop a matrix based on the discussion of Chinese firms’ investment behavior in the foreign environment in which they operate. We describe the theoretical distinctions between investments in NRR global regions, such as Africa and Central Asia, and TI regions, such as Europe and North America, with regard to technology acquisition, creation, co-creation, and transfer. We identify several research sub-themes (e.g., control and learning mechanisms, technology transfer, intellectual property, etc.) that remain under-investigated and suggest future research opportunities.

Over the twentieth century, the Vienna Philharmonic—Austria’s flagship musical institution—became a leading player in global musical life through intercontinental touring, the distribution of recordings, and the establishment of “Austrianness” as a global brand. By framing the mobility of musicians as “world practices,” this article investigates the driving forces behind an Austrian ensemble going global. It understands the Philharmonic’s relation to the music world as an entangled history of globalizing tour destinations, cultural diplomacy, non-European audiences, the agents and interests in the music market, and musical branding. The attitudes that become visible in relation to the musicians’ global mobility and their reluctance to admit non-European players bear witness to the disruptive dimensions of world practices. In conclusion, this article proposes the Philharmonic’s entanglements with Europe, the Americas, East Asia, and the Middle East as an entry point for writing a global history of twentieth-century Austrian culture.

The rare Pb silicate jagoite, known only from the Långban and Pajsberg Mn–Fe oxide deposits in Värmland, Sweden, is associated with a more diverse mineral assemblage than originally described: alamosite, barysilite, hyttsjöite, margarosanite, melanotekite, nasonite and yangite and other, not fully characterised Pb silicates. Primary melanotekite and barysilite, formed as skarn (together with hematite, quartz, clinopyroxene and andradite) during regional metamorphism, are prone to alteration, with Cl⁻, SiO₂, Ca2⁺ and H₂O acting as modifying agents. In the process, newly formed Pb silicates exhibit increasing Si content, reflecting a higher degree of SiO₄ polymerisation at high pH and decreasing temperatures.

A refinement of the crystal structure of jagoite from X-ray diffraction data, to R1 = 1.2% [space group P$\bar 6$2c, a = 8.53926(5) Å and c = 33.3399(2) Å], confirms previous work, and provides significantly improved structural parameters. New data were also obtained with Mössbauer spectroscopy, laser-Raman micro-spectroscopy, electron-microprobe and laser-ablation inductively coupled plasma mass spectrometry analyses. The results indicate that jagoite accommodates minor elements, notably Al at an octahedrally coordinated Fe-dominated site and Mn3⁺, Zn and Mg at four-coordinated mixed Fe–Si sites, and small amounts of Ca+Na replacing Pb. Jagoite is also enriched in Be, Sb, Bi and Br, but those elements have a limited role in its crystal chemistry. Mössbauer measurements show that Fe3⁺ is distributed over three different crystallographic sites, two 4-coordinated and one 6-coordinated, and that jagoite remains paramagnetic down to 77 K. The ideal chemical formula for jagoite should be written Pb11Fe5Si12O41Cl3 for Z = 2.
