Sociolinguists study the valorization of specific languages as a ‘language ideology’. Contemporary nation-states frequently identify with and promote specific languages. Such linguistic nationalism is a language ideology, but not the only one. This article examines earlier millennia to uncover the dynamics by which imperial systems managed linguistic diversity and how and why they favored and disfavored particular languages and scripts. I analyze states and empires as coalitions of interest groups. I invoke the scribal masters of imperial chanceries and archives as one such group. I develop a heuristic framework (or “model”) to understand the interactions of language and power that unfolded across West and South Asia. I begin with a great empire, the Persian, that did not employ its founders’ ethnic speech but instead refined an older state language in governance. That choice entrenched an interest group that endured through a thousand years till displaced by Arab conquest after 660 CE. But a simpler ‘New Persian’ revived in the eastern Iranian lands. Turkish and Mongol conquest elites emerging from Inner Asia carried this language and its scribes into their growing domains in the Indian subcontinent. I then explain why the non-Persian Mughals in the 1550s selected Persian as their state language and rejected the constant pressure to use Urdu creole. Mughal rule left behind a tenacious Persian-writing elite that the early British empire employed. Finally, I explain the state processes behind the colonial-era decline of Persianate administration and the emergence of a new linguistic politics in colonial India.

Critical Race Theory (CRT) has become a flashpoint of elite political discord, yet how Americans actually perceive CRT is unclear. We theorize that Republican elites utilized a strong framing strategy to re-define CRT as an “empty signifier” representing broader racial and cultural grievances. Using a survey and a pre-registered experiment among U.S. adults (N = 19,060), we find that this strategy worked. Republicans exhibit more familiarity with CRT and hold more negatively valenced (and wide ranging) sentiments toward CRT, relative to Democrats. Moreover, compared to teaching the legacy of racism in schools, Republicans are significantly more opposed to teaching CRT while Democrats express greater uncertainty. Our findings suggest that by framing CRT as a broad term that envelopes many grievances (including those beyond the scope of CRT), Republican elites have shaped a subset of Americans’ understanding of and attitudes toward CRT.

The rise and proliferation of International Commercial Courts has become a perceptible trend across the European and Asian continents over the past two decades. One such dispute resolution hub exists within the Astana International Financial Centre, a special jurisdiction within the Republic of Kazakhstan that operates on the basis of common law principles. The Astana International Financial Centre and its Court were modelled on the international financial centres of Dubai and Qatar; however, there are substantial differences between the legal systems of the Gulf States and that of the Republic of Kazakhstan. As a result, the creation of a new court has led to considerable criticism within the local legal community, raising serious doubts as to whether the Kazakh state should be maintaining and financing a ‘caviar-court’ instead of using resources to reform and develop the national judicial system. Nevertheless, despite the scepticism surrounding the financial centre, there is potential for the Astana International Financial Centre and its Court to become a regional dispute resolution hub for post-Soviet countries and the Central Asian region, following the example of Singapore and Dubai.

In their timely article, Andrew Little and Anne Meng make an important point. Despite widespread alarm over democratic backsliding, objective evidence suggests that the scale of the phenomenon is much more limited than many seem to think. Recent power holders around the world have not been entrenching themselves more effectively than in the past. Incumbents continue to lose elections about as often as they used to, and those who win have not been doing so by larger margins. Opposition parties are allowed to compete about as frequently today as 10 or 20 years ago. Moreover, there has been no increase in leaders’ ability to evade term limits.

This paper proposes a robust control approach to achieve high-precision trajectory tracking for permanent magnet linear motor (PMLM) system containing uncertainties by describing the dynamic model of PMLM based on the Udwadia-Kalaba equation combined with constraint-following method. First, the system of PMLM is described as a constraint-following system by adding the generalized constraint force to the unconstrained Udwadia-Kalaba equation of PMLM system. Second, the robust constraint-following controller is designed based on the proposed model after uncertainty analysis. Moreover, the proposed controller is verified to guarantee deterministic performance for uncertain systems: uniformly bounded and uniformly ultimately bounded. Third, the numerical simulation and experimental validation demonstrate the effectiveness of proposed controller. Finally, the design approach of constraint-following can be applied to other systems with uncertainties.

In a short, accessible book Linguistics: Why it Matters, Geoffrey Pullum, a leader in the field, offered an overview of what the study of linguistics is for the lay reader. In the penultimate chapter, titled ‘Machines that understand us’, Pullum (2018) set out to show what it would mean for computers to be able to use language like a human. He argued it would have to go beyond simple spoken or written word recognition and include processing of complex and novel structures. In this article, using ChatGPT, I revisit the tests that Pullum originally ran with Google and Microsoft Word, likewise for an audience curious about, but unfamiliar with, large language models.

In Standard Yiddish, -s and -ən are used as default allomorphs for plural word formation. It is argued here that the choice is left to the phonology, with -s acting as a default within a default. This status is used to explain the exclusive use of -s in the pluralization of proper names, which are claimed to be formed with no sensitivity to the phonological form of the base.

We present a unified approach to the processes of inversion and duality for quasilinear and $1$-quasilinear maps; in particular, for centralizers and differentials generated by interpolation methods.

This review aims to emphasise the impact of poor nutrition on children’s health and psychological well-being, urging those involved in childhood obesity or nutrition services to broaden their intervention approach. Poor nutrition and childhood obesity affect physical and psychological health. The stress of living with obesity further impacts quality of life, well-being and self-esteem. Children living with obesity may experience adverse childhood events and stress, and young people are able to recall the impact of psychosocial issues such as experiencing stigma and discrimination. Food is often a coping mechanism for managing negative emotions, perpetuating cycles of emotional coping and unhealthy eating behaviours. UK guidelines recommend family-based, multi-component weight management interventions for children living with obesity. Interventions mainly target health behaviours and utilise behaviour change techniques attempting to directly improve diet and physical activity as behavioural outcomes. Whilst these interventions may show some improvements in psychological well-being, there is limited consideration or understanding of the underlying mechanisms of action which indirectly influence engagement and the sustainability of the behaviour change. Lack of attention and inclusion of psychosocial variables in intervention implementation may help explain the variable effectiveness reported across childhood obesity interventions. In conclusion, enhancing the effectiveness of childhood obesity interventions requires a broader approach that fully incorporates psychosocial factors. Those responsible for commissioning, designing and implementing these interventions should adopt a holistic approach that addresses psychological and emotional needs while incorporating underlying mechanisms of action. This shift in focus could result in more sustainable and comprehensive treatment for childhood obesity.
