We present a method for identifying radio stellar sources using their proper-motion. We demonstrate this method using the FIRST, VLASS, RACS-low and RACS-mid radio surveys, and astrometric information from Gaia Data Release 3. We find eight stellar radio sources using this method, two of which have not previously been identified in the literature as radio stars. We determine that this method probes distances of $\sim$90pc when we use FIRST and RACS-mid, and $\sim$250pc when we use FIRST and VLASS. We investigate the time baselines required by current and future radio sky surveys to detect the eight sources we found, with the SKA (6.7 GHz) requiring $<$3 yr between observations to find all eight sources. We also identify nine previously known and 43 candidate variable radio stellar sources that are detected in FIRST (1.4 GHz) but are not detected in RACS-mid (1.37 GHz). This shows that many stellar radio sources are variable, and that surveys with multiple epochs can detect a more complete sample of stellar radio sources.

Poverty brome (Bromus sterilis L.) [sterile or barren brome, syn. Anisantha sterilis (L.) Nevski] is a problematic UK arable weed. There are currently no confirmed cases of glyphosate resistance in any weed species in the United Kingdom or in B. sterilis worldwide. However, there are reports of poor control by glyphosate in this species. Here, we report experiments to confirm the suspected on-farm resistance of B. sterilis populations to glyphosate. Glyphosate screening and dose–response experiments established that glyphosate sensitivity of three UK B. sterilis populations exhibiting poor field control is outside the normal range of sensitivity of 30 sensitive populations and adjacent unexposed populations. Control of sensitive populations ranged from 49% to 82% and for suspected resistant populations from 21% to 30%. Dose–response ED50 values of sensitive populations ranged between 241 and 313 g ai ha−1; corresponding values of suspected resistant populations ranged between 420 and 810 g ha−1, and resistance indices ranged from 1.55 to 4.5. Suspected resistant populations were incompletely controlled at the recommended field rate of glyphosate (540 g ha−1), while adjacent unexposed populations were completely controlled. We conclude that some UK populations of B. sterilis have reduced glyphosate sensitivity and are in the process of evolving resistance. This is the first reported case of reduced glyphosate sensitivity in any UK weed species and in B. sterilis worldwide. This, coupled with increasing glyphosate use, highlights the need for increased vigilance and monitoring for glyphosate resistance in the United Kingdom.

Summary
On his author website, M. G. Vassanji makes his own multinational status clear: ‘If pressed, Vassanji considers himself African Asian Canadian; attempts to pigeonhole him along communal (religious) or other lines, however, he considers narrow-minded, malicious, and oppressive.’ One of the vanguard of writers from the South Asian diaspora in Canada, Vassanji is indisputably at the core of contemporary Canadian writing. Having won the Commonwealth Writers' Prize (Africa) and twice the Giller Award (one of Canada's most prestigious literary prizes), and having been awarded the Order of Canada in recognition of his literary service to the country, it is fruitful to ponder why Vassanji's work has been so successful with a Canadian audience, in university settings and for a public readership, and with global readers alike.
Vassanji has without question reached the status of a major author. In addition to his awards, he has been reviewed in newspapers and magazines around the world and been interviewed by high-profile talk show hosts on radio and television. His fiction is studied in universities and high schools and read in book clubs and coffee shops. I suggest that Vassanji's negotiation of the complexities of ‘Indo’, ‘African’ and ‘Canadian’ identities in his fiction and nonfiction (set in India, Kenya, Tanzania and Canada) as well as in his own editorial and critical work, contribute to the ever-fluctuating conversations in public discourse about globalization, migration and flexible conceptions of home and national affiliation.

Summary
Introduction
Thyroid cancer consists of a diverse group of tumours with different clinical features and prognoses. Thyroid cancer can occur at any age, but it is rare in patients under the age of 25. Radiation exposure is the best-documented risk factor. Most thyroid cancers are carcinomas: these are papillary, follicular, medullary, and anaplastic, in order of frequency. Thyroid lymphomas and sarcomas are rarer. The overall prognosis is related to histological type; well-differentiated thyroid cancer (papillary and follicular) has the best prognosis. In contrast, anaplastic carcinoma progresses rapidly and has a very poor prognosis. There is a lack of evidence from prospective randomised controlled studies because differentiated thyroid cancer is an uncommon disease with a long natural history. Many areas of thyroid cancer management remain controversial, including the extent of surgery and the indications for radioiodine ablation and radiotherapy. Evidence-based guidelines published in 2002 relied on large retrospective and cohort studies (British Thyroid Association, 2002).
This chapter focuses mainly on differentiated thyroid cancer, with shorter sections on medullary thyroid carcinoma (MTC), anaplastic thyroid cancer and thyroid lymphoma.
Types of thyroid tumour
Thyroid tumours can be divided into benign, malignant primary and malignant secondary. Types of thyroid tumour are shown in Table 35.1.
The relative proportions of patients with differentiated thyroid cancer in a geographic area depend on dietary iodine intake. The proportion of follicular cancers increases where there is dietary iodine deficiency.

Summary
Introduction
It is not possible in a book with this format to discuss the treatment details for each tumour type, stage and subsite. This chapter highlights treatment principles and controversies.
This chapter covers the anatomical sites of the lip, oral cavity, pharynx, larynx, nose, paranasal sinuses, salivary glands, middle ear and squamous carcinoma of unknown primary. The first section considers general features of head and neck cancer. Subsequent sections focus on specific tumour sites.
General features of head and neck tumours
Types of head and neck tumour
The majority of head and neck cancers are squamous carcinomas, which account for 90% of all cases. The range of tumours is shown in Table 8.1.
Incidence and epidemiology of head and neck tumours
Approximately 8000 new cases occur per year in England and Wales (CRUK, 2004).
Approximately 3000 deaths occur per year in England and Wales (CRUK, 2004).
The UK annual incidence is approximately 14/100,000 cases per year (CRUK, 2004).
Regional variation in the UK is 8 per 100,000 in the Thames region compared to 13 to 15 per 100,000 in Wales and northwest England (NICE, 2004).
Head and neck tumours are more common in males than females (male-to-female ratio of 2:1), except for salivary gland tumours.
Incidence increases from middle age, with peak incidence occurring in the 60- to 75-age group.
Risk factors and aetiology for head and neck tumours
Prolonged exposure to environmental factors plays a key role.

An atraumatic clavicular fracture presented after radical treatment for laryngeal carcinoma. This presented a diagnostic dilemma. The differential diagnosis included metastatic bone disease and osteomyelitis as well as post-radiotherapy complications. After investigation, the cause was thought to be a post-radiation fracture of the clavicle and to the best knowledge of the authors, this is the first ever documented in a patient who had undergone a total laryngectomy with bilateral modified radical neck dissections and post-operative radiotherapy. Cases of a fractured clavicle post-radiation have been most commonly documented in patients with breast cancer and only a few cases have been documented in patients with laryngeal cancer treated with a total laryngectomy, bilateral radical neck dissections and radiotherapy.
