Tourism employment paradoxes, 1946–2095 : a perspective article

This paper addresses employment in the global tourism industry, searching for evidence for change since 1946 and then casting a speculative gaze forward to 2095. Unlike most facets of the tourism industry, there is a studied argument of limited changes to its employment conditions over the past 75 years. Indeed, Baum and Mooney (2019), casting back to 1933, argue that many of the conditions that underpinned work in the hospitality industry at the time remain identifiable in today’s industry environment. These are apparent in the early work of Whyte’s (1948, 1949) analysis of US restaurant workers and Chivers’ (1973) study of chefs in the United Kingdom. Authors such as Smeral (2004), Baum (2018), and Ioannides and Zampoukos (2018) highlight industry workplace characteristics that, inter alia, include precarity, low pay, poor working conditions and intersectional disadvantage seen in jobs of often low quality for women and migrants (Mooney et al., 2017; Robinson et al., 2019). If this ‘no change’ status is indeed a fair depiction of the industry, there appear few grounds to anticipate any significant changes in the future

A sustainable hospitality and tourism workforce research agenda – exploring the past to create a vision for the future

This chapter addresses the need for a research agenda to achieve the goal of a sustainable hospitality and tourism workforce, globally. Inhospitable working conditions, as well as the exploitation of vulnerable workers, is widespread in the sector across different locations and contexts (McIntosh and Harris 2012). Yet attention paid to these issues is marginal, not only in the sustainable tourism debate (Baum 2018; Baum et al. 2016a) but in other arenas of tourism development. The neglect may be attributable to the tourism academy’s tendency to avoid contentious or unpalatable topics (Mooney et al. 2017; Ram et al. 2016, p. 201). However, it may also result from the ‘disconnect’ between separate avenues of research in tourism and hospitality institutions, namely studies which focus on the tourist experience; tourism and hospitality management; and critical management research, which explores the employment of individuals in the sector, frequently taking a ‘problematizing’ view. In the tourism management literature, the extant literature has focused on the ways individuals negotiate their working lives or how particular organizations engage with their workers (Baum 2013; Baum et al. 2016b), and the interactions between levels have been neglected. Consequently, there have been few attempts to link the plethora of employment issues in tourism and hospitality. These troubling issues include, inter alia, low pay, precarious security, poor working conditions, high labour turnover, intersectional disadvantage, occupational ghettoization and employee sexual and physical abuse that can represent modern slavery. They need to be set in a wider social, cultural and economic context as the basis for coherent policy formulation

Larger, Lighter Space Telescopes by Implementing In-Space Manufacturing Concepts

There is a continuous demand for larger, lighter, and higher quality telescopes from both the astronomical and global surveillance communities one looking up and the other down. Enabling technologies must be developed and implemented that will allow this goal to be financially and technically feasible. The optical systems needed far high spatial resolution surveillance and astronomical applications require large optical, apertures with mention of future systems up to 150 meter in diameter. With traditional optical manufacturing technologies, large optical aperture means high mass and long fabrication lead times with associated high costs. Completely new approaches to optical fabrication must be developed to enable the fabrication of such optical systems. The cost and lead time associated with the fabrication of lightweight, high quality optical systems limits the feasible size of the optics. A primary factor in the launch cost of space optical systems is volume and mass. To minimize the mass of the high quality optics, optical fabricators implement materials with high specific stiffness and use honeycomb, or other structural minimization patterns, to support the optical surface; however, the structure must still be designed to survive launch loads. This sigmficantly adds to the fabrication difficulty and dramatically increases launch costs. One approach to minimizing launch volume and negating the need for the design to survive launch loads is to send the manufacturing facility and raw materials into space and perform the fabrication in-situ. We, are currently performing feasibility studies of initial concepts for inspace manufacturing of optical systems. By utilizing the micro-gravity and vacuum environment of space while eliminating the constraints defined by high launch forces and limited volume of the launch vehicle, the development of large, high quality glass membrane mirrors may be feasible. Several concepts were investigated to address the manufacturing of both optical surfaces and telescope structure. We will describe one of the primary approaches to utilize the space environment for optical manufacturing and describe initial results

Indentation Plastometry for Study of Anisotropy and Inhomogeneity in Maraging Steel Produced by Laser Powder Bed Fusion

This work concerns the use of profilometry-based indentation plastometry (PIP) to obtain mechanical property information for maraging steel samples produced via an additive manufacturing route (laser powder bed fusion). Bars are produced in both “horizontal” (all material close to the build plate) and “vertical” (progressively increasing distance from the build plate) configurations. Samples are mechanically tested in both as-built and age-hardened conditions. Stress–strain curves from uniaxial testing (tensile and compressive) are compared with those from PIP testing. Tensile test data suggest significant anisotropy, with the horizontal direction harder than the vertical direction. However, systematic compressive tests, allowing curves to be obtained for both build and transverse directions in various locations, indicate that there is no anisotropy anywhere in these materials. This is consistent with electron backscattered diffraction results, indicating that there is no significant texture in these materials. It is also consistent with the outcomes of PIP testing, which can detect anisotropy with high sensitivity. Furthermore, both PIP testing and compression testing results indicate that the changing growth conditions at different distances from the build plate can lead to strength variations. It seems likely that what has previously been interpreted as anisotropy in the tensile response is in fact due to inhomogeneity of this type

Lanthanum associated abnormal liver function tests in two patients on dialysis: a case report

Lanthanum (La) is a phosphate binder used in patients on dialysis in the UK. As it has only recently been in use, there are no long-term data about safety of this rare metal in human subjects with renal failure on renal replacement therapy. La has not been previously reported to cause any adverse reactions apart from nausea, sickness, dialysis graft occlusion and abdominal pain. We report here La induced abnormal liver function tests in a male and a female patient of 70 and 44 years old each, on peritoneal dialysis (PD) and haemodialysis (HD) respectively, the first report of such an adverse reaction to this agent

Atypical haemolytic uraemic syndrome presenting initially as suspected meningococcal disease: a case report

<p>Abstract</p> <p>Background</p> <p>Haemolytic uraemic syndrome (HUS) is the most common cause of acute renal failure in children and is usually linked with Escherichia coli O157 infection. With a fatality rate of around 5%, some reports have associated antibiotic treatment with a worsening prognosis.</p> <p>Case Presentation</p> <p>We describe a female infant patient, initially treated for suspected meningococcal septicaemia, who went on to develop renal complications and thrombocytopenia characteristic of HUS. A subsequent positive stool sample for <it>E. coli </it>O157 confirmed HUS as an appropriate diagnosis, although there was no evidence of diarrhoea or vomiting throughout the course of her management.</p> <p>Conclusion</p> <p>The urgency of early recognition and treatment for suspected meningococcal disease in very young children while entirely appropriate can initially divert attention from other serious conditions. Evidence of infection with <it>E. coli </it>O157 infection in this case also highlights what can be a blurred distinction between atypical (non-diarrhoeal) HUS from classical HUS of infective origin.</p

Study protocol for the Multiple Symptoms Study 3: a pragmatic, randomised controlled trial of a clinic for patients with persistent (medically unexplained) physical symptoms

Introduction: Persistent physical symptoms (which cannot be adequately attributed to physical disease) affect around 1 million people (2% of adults) in the UK. They affect patients’ quality of life and account for at least one third of referrals from General Practitioners (GPs) to specialists. These referrals give patients little benefit but have a real cost to health services time and diagnostic resources. The symptoms clinic has been designed to help people make sense of persistent physical symptoms (especially if medical tests have been negative) and to reduce the impact of symptoms on daily life. Methods and analysis: This pragmatic, multicentre, randomised controlled trial will assess the clinical and cost-effectiveness of the symptoms clinic intervention plus usual care compared with usual care alone. Patients were identified through GP searches and mail-outs and recruited by the central research team. 354 participants were recruited and individually randomised (1:1). The primary outcome is the self-reported Physical Health Questionnaire-15 at 52 weeks postrandomisation. Secondary outcome measures include the EuroQol 5 dimension 5 level and healthcare resource use. Outcome measures will also be collected at 13 and 26 weeks postrandomisation. A process evaluation will be conducted including consultation content analysis and interviews with participants and key stakeholders. Ethics and dissemination: Ethics approval has been obtained via Greater Manchester Central Research Ethics Committee (Reference 18/NW/0422). The results of the trial will be submitted for publication in peer-reviewed journals, presented at relevant conferences and disseminated to trial participants and patient interest groups. Trial registration number: ISRCTN57050216

Effectiveness of a symptom-clinic intervention delivered by general practitioners with an extended role for people with multiple and persistent physical symptoms in England:the Multiple Symptoms Study 3 pragmatic, multicentre, parallel-group, individually randomised controlled trial

BACKGROUND: People with multiple and persistent physical symptoms have impaired quality of life and poor experiences of health care. We aimed to evaluate the effectiveness of a community-based symptom-clinic intervention in people with multiple and persistent physical symptoms, hypothesising that this symptoms clinic plus usual care would be superior to usual care only.METHODS: The Multiple Symptoms Study 3 was a pragmatic, multicentre, parallel-group, individually randomised controlled trial conducted in 108 general practices in the UK National Health Service in four regions of England between Dec 6, 2018, and June 30, 2023. Participants were individually randomised (1:1) to the symptom-clinic intervention plus usual care or to usual care only via a computer-generated, pseudo-random list stratified by trial centre. Allocation was done by the trial statistician and concealed with a centralised, web-based randomisation system; masking participants was not possible due to the nature of the intervention. The symptom-clinic intervention was a sequence of up to four medical consultations that aimed to elicit a detailed clinical history, fully hear and validate the participant, offer rational explanations for symptoms, and assist the participant to develop ways of managing their symptoms; it was delivered by general practitioners with an extended role. The primary outcome was Patient Health Questionnaire-15 (PHQ-15) score 52 weeks after randomisation, analysed by intention to treat. The trial is registered on the ISRCTN registry (ISRCTN57050216).FINDINGS: 354 participants were randomly assigned; 178 (50%) were assigned to receive the community-based symptoms clinic plus usual care and 176 (50%) were assigned to receive usual care only. At the primary-outcome point of 52 weeks, PHQ-15 scores were 14·1 (SD 3·7) in the group receiving usual care and 12·2 (4·5) in the group receiving the intervention. The adjusted between-group difference of -1·82 (95% CI -2·67 to -0·97) was statistically significantly in favour of the intervention group (p&lt;0·0001). There were 39 adverse events in the group receiving usual care and 36 adverse events in the group receiving the intervention. There were no statistically significant between-group differences in the proportion of participants who had non-serious adverse events (-0·03, 95% CI -0·11 to 0·05) or serious adverse events (0·02, -0·02 to 0·07). No serious adverse event was deemed to be related to the trial intervention.INTERPRETATION: Our symptom-clinic intervention, which focused on explaining persistent symptoms to participants in order to support self-management, led to sustained improvement in multiple and persistent physical symptoms.FUNDING: UK National Institute for Health and Care Research.</p
