description: Homonyms are fascinating words that can cause confusion because they sound the same or are spelled the same but have different meanings. In the world of technical writing, where clarity is essential, the use of homonyms can create both challenges and opportunities. Let’s explore the features of homonyms in technical texts in a way that’s easy to understand.

Type material examined.
Thailand • 1 paratype; from the type locality; 1997; S. Panha leg.; CUMZ ver. 038.
Type locality.
“ Subkao, Huaykhakang Wildlife Sanctuary, Lansak District, Utaithani Province, 15°35'7"N, 99°18'8"E, 310 meters elevation … ” (Thailand).
Differential diagnosis.
This species differs from A. angthongensis by the shouldered last whorl and concave-conical shell (due to the strongly enlarged last whorl). Anauchen banmiensis is much more strongly spirally striated, it last whorl is more distinctly shouldered and has a wider umbilicus with a deep groove inside it (absent in A. huaykhakang). For differences from A. utaithaniensis, see under that species.
Distribution.
This species is known only from the type locality.

South Africa distribution: Port Nolloth to Cape Point (WC) and possibly to Port Alfred, (EC).
Remarks: Off the west coast of South Africa this is an offshore species of the outer shelf and upper slope that appears to occupy a relative narrow range, mostly between 150–400 m depth and from Port Nolloth to Cape Point (Compagno et al., 1991). Records of it along the south coast extending it eastwards to Port Alfred and possibly KZN should be carefully examined to confirm its identification as it may be mistaken for other Squalus species.

description: Incorporating diverse perspectives, especially women’s, in emerging tech development is crucial for innovation, sustainable product design, and ethical integrity. However, women remain underrepresented in STEM fields. We present insights into our RockStartIT initiative, tailored to increase girls’ interest in CS. By offering interdisciplinary courses aligned with students’ interests, RockStartIT has successfully engaged diverse groups of high school students. Through engaging expeditions, participants explore the beauty of CS in different contexts and its applications in solving real-world challenges closely aligned to their everyday experiences. We also introduce our IDEA framework, emphasizing inclusivity and interdisciplinary learning. With this approach, we aim to provide alternative pathways into CS education. By leveraging students’ individual interests, RockStartIT fosters inclusivity and promotes a deeper understanding of CS’s interdisciplinary nature.

description: Within a joint experimental and theoretical research project, single photoionization of He-like B$^{3+}$ ions was investigated in the energy range from approximately 250 to 1200~eV. With the parent-ion beam in the experiment containing both $1s^2~^1S$ ground-state and $1s2s~^3S$ metastable B$^{3+}$ ions, double-core-hole resonances could be studied. Two series of hollow resonant states were observed, one populated by $K$-shell double excitation $1s^2~^1S \to 2\ell n\ell'~^1P$ ($\ell=s,p$; $\ell'=p,s$; $n=2,3,..,6$) at photon energies up to about 510~eV, the other by $K$-shell single excitation $1s2s~^3S \to 2\ell n\ell'~^3P$ ($\ell=s,p$; $\ell'=p,s$; $n=2,3,..,6$) at energies up to about 310~eV. High resolving powers up to approximately 29000 were achieved. The relativistic many-body perturbation theory was employed to determine level-to-level cross sections for $K$-shell excitation with subsequent autoionization. The resonance energies were calculated with inclusion of electron correlation and radiative contributions. The energy uncertainties of the most prominent resonances are estimated to be below $\pm 1$ meV. Convergent close coupling (CCC) calculations provided single-photoionization cross sections $σ_{34}$ for B$^{3+}$ including the resonant and non-resonant channels. Apart from the resonances, $σ_{34}$ is dominated by direct ionization in the investigated energy range. The contribution $σ_{34}^{\mathrm{dir}}$ of the latter process to $σ_{34}$ was separately determined by using the random-phase approximation with exchange and relativistic Hartree-Fock calculations which agree very well with previous calculations. Direct ionization of one electron accompanied by excitation of the remaining electron was treated by the CCC theory and found to be a minor contribution to $σ_{34}$.

The effect of renewable energy aid and governance quality on environmental tax effort in Sub-Saharan Africa

description: The literature on foreign aid and tax efforts largely overlooks the specific role of environmental aid and taxation. To fill this gap, we examine the effects of renewable energy development assistance (EDA) and governance quality on climate change tax effort, air pollution tax effort, and aggregate environmental tax effort in Sub- Saharan Africa (SSA). Utilizing panel data from 15 SSA countries over 20 years (2000–2019), the sample is divided into two groups based on income levels: seven low-income countries (LIC) and eight middle-income countries (MIC). The instrumental variable generalized method of moments (IV-GMM) regression technique is employed to estimate the parameters of the baseline model specifications. The study also uses the Smoothed Instrumental Variable Quantile Regression (SIVQR) technique to test the robustness of the baseline model. Among middle-income SSA countries, the findings suggest that renewable energy aid inflows reduce climate change tax efforts but increase air pollution and aggregate environmental tax efforts. However, among low- income SSA countries, renewable energy aid negatively impacts all three categories of environmental tax efforts. Governance quality tends to enhance all three categories of environmental tax effort in both low-income and middle-income SSA countries. The implications of these results are discussed.

South Africa voucher material: SAIAB 25920, SAIAB 25922. Specimens in South African museum collections identified as C. granulosus and other unidentified species should be re-examined to confirm their identification as C. uyato.
South Africa distribution: Off the west coast from the Orange River (NC) and most likely off the EC and KZN.
Remarks: In South African waters, both C. granulosus and C. uyato occur, but historically have been misidentified. Compagno et al. (1991) listed C. uyato in synonymy with C. granulosus, but there were in fact two species involved: a large species now known to be C. granulosus and a small species now referred to as C. uyato. In addition, a third species, C. lesliei, recently described from West Africa and the Mozambique Channel, is likely to eventually be found in South African waters. The species name C. uyato has been problematic since it appears to have been based on a species of Squalus from the Mediterranean Sea. However, only one species of Centrophorus occurs in the Mediterranean Sea and it has incorrectly been referred to as C. granulosus. A review of the genus is presently ongoing to clarify the status of this small species of Centrophorus (D.A. Ebert, W.T. White, unpubl. data).

description: This five-year study (2016–2021) across diverse Moroccan agro-climatic zones investigated genotype by environment (G × E) interactions in wheat, focusing on variations in agronomic traits and quality attributes such as protein and gluten content. Significant environmental effects were observed on key traits, like yield, thousand kernel weight (TKW), and spikes per square meter (Spk/m2), highlighting environmental factors’ role in wheat yield variability. In the Tassaout (TST) location, notable genotypic effects emerged for traits like biomass, underscoring genetic factors’ importance in specific contexts, while in Sidi El Aidi (SEA) and Marchouch (MCH), genotypic effects on yield and its components were predominantly absent, indicating a more substantial environmental influence. These findings illustrate the complexity of G × E interactions and the need for breeding strategies considering genetic potential and environmental adaptability, especially given the trade-offs between yield enhancement and quality maintenance. Insights from the biplot and heatmap analyses enhanced the understanding of genotypes’ dynamic interactions with environmental factors, establishing a basis for strategic genotype selection and management to optimize wheat yield and quality. This research contributes to sustainable wheat breeding in Morocco, aligning with global efforts to adapt wheat breeding strategies to changing climatic conditions.

South Africa distribution: The Orange River (NC) to at least Algoa Bay (EC).
Remarks: This species is quite common off the west coast between the Orange River to Cape Point, but is likely to be widespread off the South African east coast, including KZN. The species often occurs in considerable numbers, indicating it schools or aggregates (Compagno et al., 1991). It is also frequently caught in association with large numbers of D. profundorum (D.A. Ebert, pers. obs.). During a series of surveys along the Madagascar Ridge it was also found to be common and frequently encountered in association with D. profundorum (D.A. Ebert, unpubl. data).
Conservation status: NT (2020).

description: Although entrepreneurial failure (EF) is a fairly recent topic in entrepreneurship literature, the number of publications has been growing dynamically and particularly rapidly. Our systematic review maps and integrates the research on EF based on a multi-method approach to give structure and consistency to this fragmented field of research. The results reveal that the field revolves around six thematic clusters of EF: 1) Soft underpinnings of EF, 2) Contextuality of EF, 3) Perception of EF, 4) Two-sided effects of EF, 5) Multi-stage EF effects, and 6) Institutional drivers of EF. An integrative framework of the positive and negative effects of entrepreneurial failure is proposed, and a research agenda is suggested.

description: Deania hystricosa (Garman, 1906)
Rough Longnose Dogfish
Acanthidium hystricosum Garman, 1906: 206. Holotype (unique): MCZ 1130 -S [ex Owston #7784] (missing). Type locality: Sagami Bay, Japan.
Local synonymy: Deania hystricosum: Compagno, 1999: 114. Deania hystricosa: Compagno et al., 2005: 88, pl. 5; Ebert et al., 2013 a: 108, fig., pl. 7; Compagno, 2016: 1175; Weigmann, 2016: 891.
South Africa voucher material: None.
South Africa distribution: Possibly off the west coast (NC & WC), but the occurrence in South African waters is uncertain.
Remarks: Compagno (1999) listed this species as occurring in southern African waters, while Compagno et al. (2005) reported it occurs off the west coast of South Africa. However, the occurrence of this species in South African waters requires confirmation since no specimens are currently available for examination.
Conservation status: DD (2009).
