This article enquires into colonial officials’ invocations of the “rule of law” and the persistence of racial difference in the modern British Empire. To unravel this contradiction, I examine the debates over the freedom of women during the repeal of the Contagious Diseases ordinances in the directly ruled Crown Colonies of Hong Kong and the Straits Settlements (Singapore, Penang, and Malacca) between 1886 and 1890. Although the apparent purpose of these laws was the containment of venereal diseases, officials employed them to police prostitution and subject working-class, “native” women to medical surveillance. Despite the repeal of the Contagious Diseases ordinances across the empire, officials in both colonies continued to regulate prostitution in the name of native women’s freedom, invoking the rule of law. Through the historical ethnography of the rule of law, I demonstrate how the language of this ideal rendered an evocative frame of beneficence, legality, and protection against which officials articulated social difference in racialized, and intersectional, ways—what I call racialized legalities. In comparing the colonized in terms of racialized legalities, officials designed a differentiated sovereignty in determining the protections granted to native women. Expressing the cultural power of law, the rule of law was a constitutive myth.

Trace elements may play an important role in obesity. This study aimed to assess the plasma and dietary intake levels of four trace elements, Mn, Cu, Zn and Se in a rural Chinese population, and analyse the relationship between trace elements and obesity. A cross-sectional study involving 2587 participants was conducted. Logistic regression models were used to analyse the association between trace elements and obesity; restricted cubic spline (RCS) models were used to assess the dose–response relationship between trace elements and obesity; the weighted quantile sum (WQS) model was used to examine the potential interaction of four plasma trace elements on obesity. Logistic regression analysis showed that plasma Se concentrations in the fourth quartile (Q4) exhibited a lower risk of developing obesity than the first quartile (Q1) (central obesity: OR = 0·634, P = 0·002; general obesity: OR = 0·525, P = 0·005). Plasma Zn concentration in the third quartile (Q3) showed a lower risk of developing obesity in general obesity compared with the first quartile (Q1) (OR = 0·625, P = 0·036). In general obesity, the risk of morbidity was 1·727 and 1·923 times higher for the second and third (Q2, Q3) quartiles of dietary Mn intake than for Q1, respectively. RCS indicated an inverse U-shaped correlation between plasma Se and obesity. WQS revealed the combined effects of four trace elements were negatively associated with central obesity. Plasma Zn and Se were negatively associated with obesity, and dietary Mn was positively associated with obesity. The combined action of the four plasma trace elements had a negative effect on obesity.

The purpose of this service-learning action research study was to develop and investigate after-school individualised vocal lessons for secondary students aged 14–18 years (n = 15) taught by preservice music educators (PMEs) (n = 12) in the United States. In service learning, all parties should benefit from the experience while addressing curricular and community needs. Therefore, our intentions were to: (a) improve secondary student preparedness for solo experiences, (b) provide an authentic teaching experience to improve the quality of instruction given by PMEs, and (c) develop a mutually beneficial and collaborative service-learning experience. The following themes emerged from the data: (a) perceptions of teaching disposition – such as confidence, interpersonal skills and enthusiasm; (b) perceptions of teaching skills – such as student engagement, questioning techniques and responsive teaching; and (c) perceptions of pedagogical content knowledge – such as vocal anatomy, physiology and pedagogy.

Crinoids were major constituents of late Carboniferous (Pennsylvanian) marine ecosystems, but their rapid disarticulation rates after death result in few well-preserved specimens, limiting the study of their growth. This is amplified for cladids, who had among the highest disarticulation rates of all Paleozoic crinoids due to the relatively loose suturing of the calyx plates. However, Erisocrinus typus Meek and Worthen, 1865 has been found in unusually large numbers, most preserved as cups but some as nearly complete crowns, in the Barnsdall Formation in Oklahoma. The Barnsdall Formation, a Koncentrat Lagerstätte, is composed predominantly of fine- to medium-grained sandstone, overlain by mudstone and shale; severe compaction of the fossils in the mudstone and shale layer in this formation allowed for exceptional preservation of the plates. Herein, we summarize a growth study based on 10 crowns of E. typus, showcasing a well-defined growth series of this species from the Barnsdall Formation, including fossils from juvenile stages of development, which are rarely preserved. We used high-resolution photographs imported into ImageJ and recorded measurements of the cup and arms for all nondistorted or disarticulated plates. Results show that the plates of the cup grew anisometrically with both positive and negative allometry. The primibrachial plates of E. typus grew with positive allometry. The brachial plates started as uniserial (i.e., cuneiform) as juveniles but shifted to be biserial. Erisocrinus typus broadly shares similar growth trajectories with other cladids. These growth patterns provide insight into feeding strategies and can aid in understanding crinoid evolutionary paleoecological trends.

This article analyses an interdisciplinary educational experience combining music, ICT, language and art to create an animated story with active listening as a means of improving knowledge of music education practices. The method consisted of a qualitative, exploratory and descriptive study, with a semi-structured open-ended interview and analysis of the corresponding portfolio by both students and teachers with the aim of encouraging systematic reflection on practices and optimising teaching-learning in the nature of action research. The research population consisted of 104 students of the Bachelor’s Degree in Teaching of the Faculty of Education of the University of Alicante (Spain). The results indicated an improvement in music education practices relating to active listening following the pedagogical intervention, leading to the conclusion that inclusion of ICT in music education facilitates real and effective insertion and enhances students’ autonomy in the process of acquisition of musical skills.

A small-size multiband antenna with 14 bands is presented in this paper for wireless applications. The studied antenna mainly consists of a folded monopole antenna and an M-shaped structure. Furthermore, the antenna has a simple design with a compact dimension of 26.8 × 10.8 mm2. The studied antenna is printed on FR4 substrate with a depth of 0.8 mm and fed by a coaxial cable. The −10 dB bandwidths measured are 210 MHz (1200–1410 MHz), 100 MHz (2200–2300 MHz), 193 MHz (3000–3193 MHz), 180 MHz (3330–3510 MHz), 390 MHz (4110–4500 MHz), 4971 MHz, 577 MHz (5300–5877 MHz), and 700 MHz (7100–7800 MHz), which can cover 3G/4G/5G/Wi-Fi/WiMAX, C, and S bands. The gain and efficiency of the presented antenna are 1.3–4.00 dBi and 46%–60.2%, respectively.
