We present the data and initial results from the first pilot survey of the Evolutionary Map of the Universe (EMU), observed at 944 MHz with the Australian Square Kilometre Array Pathfinder (ASKAP) telescope. The survey covers $270 \,\mathrm{deg}^2$ of an area covered by the Dark Energy Survey, reaching a depth of 25–30 $\mu\mathrm{Jy\ beam}^{-1}$ rms at a spatial resolution of $\sim$ 11–18 arcsec, resulting in a catalogue of $\sim$ 220 000 sources, of which $\sim$ 180 000 are single-component sources. Here we present the catalogue of single-component sources, together with (where available) optical and infrared cross-identifications, classifications, and redshifts. This survey explores a new region of parameter space compared to previous surveys. Specifically, the EMU Pilot Survey has a high density of sources, and also a high sensitivity to low surface brightness emission. These properties result in the detection of types of sources that were rarely seen in or absent from previous surveys. We present some of these new results here.

Referrals (particularly natal female) to gender identity clinics have increased significantly in recent years. Understanding the reasons for this increase, and how to respond, is hampered by a politically charged debate regarding gender identity. This article starts with a discussion of the so-called ‘affirmative approach’ to gender dysphoria and considers the implications of the Memorandum of Understanding on conversion therapy. I then say something about the relationship between gender dysphoria and the developmental problems that are characteristic of adolescence. Finally, I outline what changes to the current approach are needed to do our best to ensure these patients receive the appropriate treatment.

This study sought to identify trajectories of DSM-IV based internalizing (INT) and externalizing (EXT) problem scores across childhood and adolescence and to provide insight into the comorbidity by modeling the co-occurrence of INT and EXT trajectories. INT and EXT were measured repeatedly between age 7 and age 15 years in over 7,000 children and analyzed using growth mixture models. Five trajectories were identified for both INT and EXT, including very low, low, decreasing, and increasing trajectories. In addition, an adolescent onset trajectory was identified for INT and a stable high trajectory was identified for EXT. Multinomial regression showed that similar EXT and INT trajectories were associated. However, the adolescent onset INT trajectory was independent of high EXT trajectories, and persisting EXT was mainly associated with decreasing INT. Sex and early life environmental risk factors predicted EXT and, to a lesser extent, INT trajectories. The association between trajectories indicates the need to consider comorbidity when a child presents with INT or EXT disorders, particularly when symptoms start early. This is less necessary when INT symptoms start at adolescence. Future studies should investigate the etiology of co-occurring INT and EXT and the specific treatment needs of these severely affected children.

Many scholars have concluded, perhaps prematurely, that information and communication technologies (ICTs) are inherently empowering for Africans. In order to look more closely at the impact of ICTs on relationships and society, this article focuses on everyday life. Specifically, it uses ethnographic methods and the theory of “affordances” to illuminate the use of cell phones among Bulsa of Ghana’s Upper East Region. While cell phones help users connect with distant loved ones, they also plant seeds of alienation between users and those who remain physically present. These changes are evident in new body habits and in social behaviors that would be culturally unacceptable in face-to-face interactions but are largely excused in the interventions of the virtual world.
