Review
Viruses are ubiquitous. They infect almost every species and are probably the most abundant biological entities on the planet, yet they are excluded from the Tree of Life (ToL). However, there can be no doubt that viruses play a significant role in evolution, the force that facilitates all life on Earth. Conceptually, viruses are regarded by many as non-living entities that hijack living cells in order to propagate. A strict separation between living and non-living entities places viruses far from the ToL, but this may be theoretically unsound. Advances in sequencing technology and comparative genomics have expanded our understanding of the evolutionary relationships between viruses and cellular organisms. Genomic and metagenomic data have revealed that co-evolution between viral and cellular genomes involves frequent horizontal gene transfer and the occasional co-option of novel functions over evolutionary time. From the giant, ameba-infecting marine viruses to the tiny Porcine circovirus harboring only two genes, viruses and their cellular hosts are ecologically and evolutionarily intertwined. When deciding how, if, and where viruses should be placed on the ToL, we should remember that the Tree functions best as a model of biological evolution on Earth, and it is important that models themselves evolve with our increasing understanding of biological systems.

The substantial literature on interactions between places/spaces and well-being/health often differentiate between physical and social aspects of geographical location. This paper sidesteps this dualism, instead considering places as sociomaterial assemblages of human and non-human materialities. It uses this posthuman and 'new materialist' perspective to explore how place-assemblages affect human capacities, in terms of both health and social dis/advantage. Based on secondary analysis of interview data on human/place interactions, it analyses the physical, sociocultural, psychological and emotional effects of place-assemblages, assessing how these produce opportunities for, and constraints upon human bodies. It than assesses how these emergent capacities affect both social dis/advantage and well-being. This analysis of how place-assemblages contribute positively or negatively to health and dis/advantage offers possibilities for further research and for social and public health policy.

Place attachment at neighborhood places can facilitate social ties and community belonging, reduce social isolation and improve physical and mental health outcomes. Research highlights the benefits of place attachment at traditional third places such as cafes and parks but is yet to examine place attachment across a broader suite of highly frequented neighborhood places. Drawing on survey data from a sample of Australian residents (N = 892) with a median age of 55-64 years, this study examines the influence of place form and function on place attachment at everyday places. Findings reveal that places where individuals go to participate in specific and unique activities (e.g., exercise at a gym, prayer at a temple) alongside a defined group of other community members, such as places of worship or gyms, engender stronger place attachment than places of economic consumption, such as large shops and cafes. This is important in its capacity to inform neighborhood planning and policies to reduce risk of social isolation.

Review
BACKGROUND
Nephrologists are often thwarted in their attempts to grow their peritoneal dialysis programs because of suboptimal surgeon performance in placing catheters. A rallying call is heard among nephrologists to step up to the role of dialysis access providers.
OBJECTIVE
What factors influence the practicability of nephrologists becoming primary dialysis access providers? Why have surgeons failed their task and can anything motivate them to change their performance and improve outcomes?
METHODS
While the issues are universal, this analysis focuses on current practice data from the United States. Evidence reviewed includes dialysis center size and annual new starts, profile of specialties performing catheter placement, nephrology workforce capacity, catheter implantation methodology, resource utilization for peritoneal access, and surgeon performance.
RESULTS
The current nephrology workforce is running at maximum capacity and fellowship training programs will struggle to meet additional demands. Nephrology training programs are often deficient in providing adequate experience in peritoneal dialysis management. Only 2.3% of peritoneal catheters are placed by nephrologists. The best catheter outcomes are produced by laparoscopic methods used by surgeons. Compared to other catheter placement techniques, laparoscopy enables a larger candidate pool of patients. Nonetheless, suboptimal surgical performances are related to inadequate training, low procedure volume, and poor reimbursement.
CONCLUSIONS
It is improbable that nephrologists can expand the scope of their practice to assume the additional role of dialysis access providers. The performance of the existing surgical workforce can be enhanced through medical society-sponsored educational activities, channeling access procedures to designated surgeons, and improved remuneration through outcomes-based incentive programs.

The present paper aims to contribute to the debate about the temporal relationships between place and health. It explores the notion of 'daycourse of place' echoing the discussion which recently occurred in this journal about the 'lifecourse of place' (Andrews, 2017; Lekkas et al., 2017a, b). When highlighting the importance of time in shaping health within places, most of studies focus either on the trajectories of places over a matter of years or the daily trajectories of people in link with their activity space. However, daily trajectories of places remain a poor cousin in place and health literature. This paper is intended to overcome 'jetlag', which places suffer when they are labelled with frozen attributes over a 24-h period. It explores the values and feasibility of exploring daily trajectories of places to investigate place effects on health or to design area-based interventions for public health action. More than just a metaphor, the 'daycourse of place' appears to be an inspiring framework to elaborate the importance of daily temporal relationalities for research and action in place-based health inequalities.

With the advent of telecare and the logic of information technologies in health care, the idea of placeless care has taken root, capturing imaginations and promising placeless caring futures. This 'de-territorialisation of care' has been challenged by studies of care practices 'on the ground', showing that care is always (materially) placed. Yet, while sociological scholarship has taken the role of place seriously, there is little conceptual attention for how we may think through immateriality and the changing nature of place in health care. Based on a case study of the introduction of a sensory reality technology into a care organisation, this paper argues that we need (1) to push the definition of placed care into new (digitally produced) landscapes and (2) a new vocabulary, with which to address and conceptualise this changing nature of care places. The paper introduces the term post-place, as a first step in developing such a vocabulary. Post-place care, unlike the idea of placeless care or emplaced care, is an inclusive, open and generative concept. Its strength lies in its disruptive potential for challenging existing place-care ontologies and opening up productive space for thinking through the changing landscapes of health care.

Since the reintroduction of sheep scab within the UK, its prevalence has increased despite several industry-led initiatives to control and manage the disease. Some studies have suggested that initiatives or policies should instead focus on specific places, such as geographically high-risk areas for sheep scab, which could allow for a more targeted approach. However, this risk of sheep scab has been measured in set geographical areas, without the reference to the interplay of topography, host, pathogen and the way in which humans socially and culturally define risk and place, potentially limiting the effectiveness of preventative initiatives. Therefore, the aim of the current study was to understand how place influences sheep farmers' approaches to the identification and management of the risk of sheep scab in their flocks. Qualitative data was collected from 43 semi-structured interviews with sheep farmers from England, Scotland, and Wales and was analysed by using the constant comparative approach. The codes were grouped into four concepts that influenced farmers' decision-making strategies for sheep scab control: perception of place; risk identification; risk categorisation; and risk management. These concepts were used as an analytical framework to identify three different 'places': 'uncontrollable places', 'liminal places' and 'protective places'. Each place reflects a different sheep scab control strategy used by farmers and shaped by their perceptions of place and risk. The 'uncontrollable places' category represented farmers who were located in areas that were geographically high-risk for sheep scab and who experienced a high frequency of sheep scab infestations in their flocks. The risk posed by their local landscape and neighbouring farmers, who neglected to engage in preventative behaviours, led them to feel unable to engage in effective risk management. Thus, they viewed scab as uncontrollable. The farmers within the 'liminal places' category were characterised as farmers who were located in high-risk areas for sheep scab, but experienced low levels of sheep scab infestations. These farmers characterised the risks associated with sheep scab management in terms of needing to protect their reputation and felt more responsibility for controlling sheep scab, which influenced them to engage in more protective measures. The farmers within the 'protective places' category were characterised as farming within low-risk areas and thus experienced a low level of sheep scab infestations. These farmers also described their risk in terms of their reputation and the responsibility they held for protecting others. However, they sought to rely on their low geographical risk of sheep scab as a main source of protection and therefore did not always engage in protective measures. These results suggest that place-based effects have significant impacts on sheep farmers' beliefs and behaviours and thus should be considered by policymakers when developing future strategies for sheep scab control.

Migrants are faced with the task of creating a sense of home in a new context. As migrants grow older in their host countries, they are also making important decisions on where to live out the rest of their lives, making salient the places they attach themselves to. Place attachment, and its subcomponents of place identity and place dependence, are concepts that have been explored in the ageing and migration literature, demonstrating that positive, emotional attachments to places are positively correlated with better health outcomes. Although it has been established that individuals' attachments to places are dynamic, multidimensional and change over the life course, there is a paucity of research exploring the place attachments of migrants as they age using a life course approach. This study adopted a life course approach to investigate how the components of place attachment shifted over time for migrant people in Aotearoa New Zealand as they aged, and to better understand the mechanisms and barriers to establishing a sense of home in a foreign land. We examined the narratives of ten older migrants (65 years or older) who migrated to Aotearoa before the age of 50. Key findings illustrated that all participants had strong place identities (i.e., explicit self-identification and sense of belonging) to their countries of origin before migrating to Aotearoa, all participants developed strong place dependence (i.e., fulfilment of functional needs) to Aotearoa over their life course, but not everyone was able to develop place identity to Aotearoa. Mechanisms such as language, cultural attitudes, and values can both facilitate and prevent attachments to either home or host country. These results uncover how Aotearoa's ageing migrants negotiate their attachments to places over the life course.

Despite calls for greater social work attention to the centrality of place in human life, the profession has yet to hone frameworks that fully capture the role of place in individual-collective identity and well-being. To move this agenda forward, this article draws on data from a series of focus groups to explore the placed experiences of women in Palestine. Analytically, it is informed by , which emphasises the deeply interactional relationships between people and places, views place-centred practice and research as catalysts for active responses to the spatialised nature of power and injustice, and focuses centrally on the geographic and spatial dynamics of colonisation, and particularly settler colonialism, as key determinants of individual and collective well-being. Women's spatial narratives revolved around individual-collective identity and sovereignty, focusing in particular on three interdependent factors: freedom of movement; possession and dispossession; and continuity of place. Findings also illuminated spatial practices of resistance by which women defend and promote identity and sovereignty. We conclude with recommendations for more explicit, critically informed attention to place in social work practice, education and research.
