Study Context

For a century, scholars have studied immigrant integration in a range of destinations. Yet, the precise role of context in shaping integration outcomes remains poorly understood. Drawing from an analysis of an original database of articles and books in migration studies, I argue that this knowledge gap may be due to two closely related tendencies in the scholarship. First, case selection has relied on criteria such as the immigrant population's size and growth rate that are not clearly connected to integration outcomes. Second, most scholars have studied either heavily urban contexts (with large immigrant populations) or very rural contexts (where the immigrant population is growing rapidly), while much less attention has been given to destinations in-between. To improve the understandings of the role of context in immigrant integration, migration scholars should endeavor to move past population criteria when selecting study sites and to study the full range of contexts where immigrants are settling. To contribute to these efforts, I propose a framework that does not rely on population or newness as criteria for case selection and that focuses, instead, on the components of context that existing research has shown matters for intergenerational mobility. I also introduce a typology of contexts based on possible combinations of four of these components and offer some initial hypotheses of how these context types might affect immigrant integration. The arguments presented here recenter the role of local context in migration studies and contribute to debates about where and how scholars should study context moving forward.

Optimal Imaging

Echocardiography provides excellent realtime imaging of the heart, making it the imaging modality of choice immediately before, during and after cardiac interventional procedures. It helps to guide case selection and execution of the intervention, evaluates the effects of the intervention and enables early detection of complications. Advances in the design and technology of medical devices and delivery systems, coupled with demand for alternative non-surgical therapies for common medical problems, have led to an increase in the volume, variety and complexity of non-coronary cardiac interventional procedures performed. Many of these procedures require a multidisciplinary team approach and demand optimal imaging to ensure successful outcomes. The aim of this article is to review the expanding role of echocardiography in non-coronary interventional cardiology in adults.

Marangoni Effects

The Marangoni effect on the critical heat flux (CHF) condition in pool boiling of binary mixtures has been identified and its effect has been quantitatively estimated with a modified model derived from hydrodynamics. The physical process of CHF in binary mixtures, and models used to describe it, are examined in the light of recent experimental evidence, accurate mixture properties, and phase equilibrium revealing a correlation to surface tension gradients and volatility. A correlation is developed from a heuristic model including the additional liquid restoring force caused by surface tension gradients. The CHF condition was determined experimentally for saturated methanol/water, 2-propanol/water, and ethylene glycol/water mixtures, over the full range of concentrations, and compared to the model. The evidence in this study demonstrates that in a mixture with large differences in surface tension, there is an additional hydrodynamic restoring force affecting the CHF condition.

The World

COVID-19 spread rapidly across the world, and by March 2020, the first case of COVID-19 was identified in South Africa. Lockdown-related measures such as restricted movement and isolation were implemented to contain the virus. Combined with these measures, factors such as economic decline, job losses, and food shortages can cause numerous mental health sequelae such as depression. Feelings of hopelessness and helplessness as well as cases of suicide have been reported around the world due to the pandemic and the associated feelings of anxiety and depression. The aims of this study were to investigate levels of hopelessness and depression in a sample of health care students. A random sample of students ( N = 174) enrolled in a health sciences programme at the University of the Western Cape completed the Beck Hopelessness Scale, the Center for Epidemiological Studies Depression Scale, and a three-item Resilience Scale. The results revealed high levels of hopelessness and depression compared to previously reported normative data for these scales. In addition, the indirect effects of hopelessness on depression were significant, demonstrating the mediating role of resilience in the hopelessness–depression relationship. These results highlight a call for universities to take proactive measures in providing students with free and easily accessible resources to help them cope and manage stress during a traumatic event. More importantly, at a national level, preventive measures should be implemented to strengthen resilience in young adults.

There is increasing interest in developing urban design principles that incorporate good ecological management. Research on understanding the distribution and role of beneficial pollinating insects, in particular, is changing our view of the ecological value of cities. With the rapid expansion of the built environment comes a need to understand how insects may be affected in extensive urban areas. We therefore investigated insect pollinator capture rates in a rapidly growing and densely urbanized city (Melbourne, Australia). We identified a remnant native habitat contained within the expansive urban boundary, and established study sites at two nearby populated urban areas. We employed standard pan trap sampling techniques to passively sample insect orders in the different environments. Our results show that, even though the types of taxonomic groups of insects captured are comparable between locations, important pollinators like bees and hoverflies were more frequently captured in the remnant native habitat. By contrast, beetles (Coleoptera) and butterflies/moths (Lepidoptera) were more frequently observed in the urban residential regions. Our results suggest that the maintenance of native habitat zones within cities is likely to be valuable for the conservation of bees and the ecosystem services they provide.

AbstractLucian’s work De historia conscribenda not only presents reflections on how one should or should not write history, but also illustrates possible ways to represent the authorial activity of a historian (i. e. how one writes ‘metahistory’). In this, two basic forms can be distinguished, both of which can be understood from a narratological perspective as metalepses. In the first case, the historian is represented as the direct originator of the action; in the second he acts as a mere observer, but one who moves spatially in and with his action. Both forms of statement stand within traditions of motifs that can be traced from antiquity through to the modern era; yet Lucian nonetheless makes an innovative contribution by inscribing value judgements into the motifs. The result is the suggestion that the historian fulfils the role of observer, while the role of originator turns out to be more apt for the poet than for the historian. This permits far-reaching conclusions to be drawn about the conception of poetry and historiography as a whole.

BackgroundIdiopathic Intracranial Hypertension (IIH), is defined by increased cerebral spinal fluid (CSF) pressure in the absence of other causes of intracranial hypertension. There has been recent interest in the role of intracranial venous sinus stenosis in IIH. The raised pressures in IIH are argued to worsen by the secondary appearance of the venous sinus stenosis.Objective5 patients have undergone endovascular pressure measurement in Wales and their clinical details including history, examination, initial management, neuroimaging pre- and post venous stenting, and follow-up (6–24 months) to provide the first case study of patients undergoing Venous sinus stenting in Wales.Methods5 patients with IIH refractory to first line treatments underwent venography and manometry and 4 patients underwent stenting of the venous sinuses after this procedure had shown a pressure gradient proximal to stenosis in the lateral sinuses.ResultsThree patients were rendered asymptomatic, two were improved including one patient unmasking a different headache disorder following treatment.ConclusionsStenting in venous stenosis provides a further treatment option to patients refractory to first line treatments with IIH. This case series highlights in selected cases treatment is promising with good outcomes.

Limited Attention

The need to address the human health implications of northern development is well founded, and the role of health determinants in environmental impact assessment is increasingly recognised; however, there is limited understanding of the nature of health determinants and current practices in northern project assessment and decision making. This paper reports on a study of the nature and use of health determinants in Canadian northern environmental impact assessment, and discusses the key challenges to, and opportunities for, improved practice. Four themes emerged from this study. First, the consideration of health is limited to physical environments and the physical determinants of health, with limited attention to broader social and cultural health determinants. Second, when health is considered in northern project impact assessments such considerations rarely carry forward to post-project approval monitoring of health determinants and evaluation of health impact management programmes. Third, while there is general consensus that health determinants should be an integral part of northern impact assessment, there exist different expectations of the role of health determinants in project evaluation and decision making due in large part to different understandings and interpretations of health. Finally, a broader conceptualisation of health and health determinants in northern environmental impact assessment is required; one that takes into consideration northern cultures and knowledge systems, and is adaptive to local context, geography and life cycles.

In February 1889 Edward King, Bishop of Lincoln, appeared before the court of the Archbishop of Canterbury charged with illegal practices in worship. The immediate occasion for these proceedings was the manner in which he celebrated Holy Communion at the Lincoln parish church of St Peter at Gowts on Sunday 4 December 1887. He was cited on six specific charges: the use of lighted candles on the altar; mixing water with the communion wine; adopting an eastward-facing position with his back to the congregation during the consecration; permitting the Agnus Dei to be sung after the consecration; making the sign of the cross at the absolution and benediction, and taking part in ablution by pouring water and wine into the chalice and paten after communion. Two Sundays later King had repeated some of these acts during a service at Lincoln Cathedral. As well as its intrinsic importance in defining the legality of the acts with which he was charged, the Bishop’s trial raised issues of considerable importance relating to the nature and exercise of authority within the Church of England and its relationship with the state. The acts for which King was tried had a further significance since the ways in which these and other innovations in worship were perceived, as well as the spirit in which they were ventured, also reflected the fundamental shifts which were taking place in the role of the Church of England at parish level in the second half of the nineteenth century. Their study in a local context such as Lincolnshire, part of King’s diocese, provides the opportunity to examine the relationship between changes in worship and developments in parish life in the period.

Objective This paper reports on a project to examine the expectations of senior nurses regarding graduate roles of registered and enrolled nurses educated in Victoria, Australia. Methods Participants completed an online survey to indicate whether predetermined competencies were in the roles of graduate enrolled or registered nurses or not in the role of either nurse. Chi-squared analysis was used to identify differences between participant groups. Results Participants expressed variations in role expectations for the different level of graduate nurse. Although basic nursing care was undertaken by both graduate enrolled and registered nurses, no specific role was identified for enrolled nurses. Differences were found in the opinions of senior nurses over the roles of graduate nurses, demonstrating considerable variation in expectations. Management, education and research roles were not identified as the role of either nurse on graduation. Differences were found in the expectations of the different senior nurse groups regarding the roles of the enrolled nurse, particularly in the new skills taught in the enrolled nurse diploma program. Conclusions Confusion exists regarding the roles of both types of nurse on graduation. Further research across Australia is required to clarify the roles of the different level of nurse in different practice contexts. What is known about the topic? Australia, like many other countries, prepares two levels of nurse for entry to practice: the degree-prepared registered nurse and the diploma-prepared enrolled nurse. Role confusion and ambiguity have been reported in the literature by many countries, including Australia, that employ two levels of nurse. What does this paper add? Great variation exists between expectations of senior nursing staff as to the role of both levels of graduate nurse. Role confusion and ambiguity exists for nurses in Australia. Role confusion and ambiguity around the scope of practice for enrolled nurses is seen as both limiting their practice and encouraging them to work at levels for which they have not been prepared. Graduate registered nurses were seen as more prepared for required graduate attributes than enrolled nurses. Care of acute, complex or deteriorating patients remains the role of registered nurses. What are the implications for practitioners? Practising nurses need to be educated as to the skills and knowledge that diploma enrolled nurses are graduating with in order to enable them to use their full range of abilities. To provide safe, quality care, registered nurses must fully understand the roles and abilities of the enrolled nurses to whom they delegate care. Organisational health policies and procedures need to be reviewed to accommodate the increased skills and knowledge of diploma-prepared enrolled nurses and enable best utilisation of their skills. Practising nurses need to be aware that enrolled nurses are not educationally prepared to care for complex or deteriorating patients. Although they are able to undertake basic nursing care, the role of caring for complex, highly acute and deteriorating patients remains in the domain of registered nurses. The increasing acuity of patients admitted to health services requires a higher skill mix of registered nurses to safely care for them.
