In a context of hyper-diversity and social polarisation, it has been suggested that public parks constitute crucial arenas in which to safeguard deliberative democracy and foster social relations that bind loosely connected strangers. Drawing on empirical research, we offer a more circumspect and nuanced understanding of the – nonetheless vital – role that parks can play in fostering civic norms that support the capacity for living with difference. As ‘spaces apart’, parks have distinctive atmospheres that afford opportunities for convivial encounters in which ‘indifference to difference’ underpins ‘openness to otherness’. As places in which difference is rendered routine and unremarkable, the potency of parks for social cohesion derives from fleeting and unanticipated interactions and the weak ties they promote, rather than strong bonds of community that tend to solidify lines of cultural differentiation. Both by design and unintentionally, regulation and law can serve to foster or constrain the conditions that sustain conviviality.

Access to an outdoor range has many potential benefits for laying hens but range use can be poor due to factors only partly understood. Techniques to monitor individual range use within commercial flocks are crucial to increase our understanding of these factors. Direct observation of individual range use is difficult and time-consuming, and automatic monitoring currently relies on equipment that is difficult to use in an on-farm setting without itself influencing range use. We evaluated the performance of a novel small, light and readily portable light-based monitoring system by validating its output against direct observations. Six commercial houses (2000 hens/house) and their adjacent ranges were used, three of which were equipped with more structures on the range than the others (to determine whether cover would influence monitoring accuracy). In each house, 14 hens were equipped with light monitoring devices for 5 discrete monitoring cycles of 7 to 8 consecutive days (at 20, 26, 32, 36 and 41 weeks of age). Light levels were determined each minute: if the reading on the hen-mounted device exceeded indoor light levels, the hen was classified as outside. Focal hens were observed directly for 5 min/hen per week. Accuracy (% of samples where monitoring and direct observations were in agreement) was high both for ranges with more and with fewer structures, although slightly better for the latter (92% v. 96% ± 1 SEM, F1,19 = 5.2, P = 0.034). Furthermore, accuracy increased over time (89%, 94%, 95%, 98% ± 1 SEM for observations at 26, 32, 36 and 41 weeks, respectively, F3,19 = 3.2, P = 0.047), probably due to progressively reduced indoor light levels resulting from partial closing of ventilation openings to sustain indoor temperature. Light-based monitoring was sufficiently accurate to indicate a tendency for a greater percentage of monitored time spent outside when more range structures were provided (more: 67%, fewer: 56%, SEM: 4, $\chi_1^2 = 2.9$ , P = 0.089). Furthermore, clear and relatively consistent individual differences were detected. Individuals that were caught outside at the start of the experiment ranged more throughout its duration (caught outside: 72%, caught inside 51%, SEM: 4, $\chi_1^2 = 10.0$ , P = 0.002), and individual range use was correlated between monitoring cycles (for adjacent monitoring cycles: $r_s^2 = 0.5-0.7$ , P < 0.0001). This emphasizes the importance of studying range use on an individual level. In conclusion, our light-based monitoring system can assess individual range use accurately (although accuracy was affected by house characteristics to some extent) and was used to show that both cover availability and individual characteristics affected range use.

This paper presents a diachronic account for the emergence of the expletive það in Icelandic impersonal constructions. Using data from the IcePaHC corpus (Wallenberg et al. 2011), I show that a cataphorically referential það functions as a topic position placeholder in Old Icelandic (1150-1350) in impersonals with a clausal argument. The corpus findings indicate that það spread from this early cataphoric context to impersonals which lack the clausal argument, with ‘say-type predicates’ acting as a bridging context. Strikingly, this coincides with another change whereby cataphoric það becomes increasingly restricted to the topic position in constructions with a clausal subject. I interpret this as evidence that cataphoric það is losing its subject status in such contexts and becoming a topic position placeholder, in line with its function in impersonals. This sheds light on the mixed status of cataphoric það in modern Icelandic and challenges the ‘Prefinite First Hypothesis’ for the diachrony of Germanic expletives (e.g. Faarlund 1990).

This article explores a series of doctrinal disputations held in early Islamic Egypt, and known through the Hodegos of Anastasius of Sinai (fl. c. 670–c. 700). Using the text's prosopographical and contextual cues, it argues that these disputations occurred in the 680s, in the aftermath of Constantinople's Sixth Ecumenical Council (680/1), the decisions of which had thrown the Chalcedonian Christians of the caliphate into conflict and schism. In 686, it is argued, Anastasius had confronted the famed Edessene and Severan Athanasius bar Gūmōyē before the Marwānid prince ‘Abd al-'Azīz at Fusṭāṭ, and there been defeated. That defeat is indicative of the new-found position of the Egyptian Severan Church, which now flourished under Marwānid patronage.
