Lives of Malawian nurses: stories behind the statistics

Malawi lost a significant proportion of its most experienced and qualified nurses to international migration between 2000 and 2005. The lure of overseas life and poor conditions of service at home caused an unprecedented wave of migration. This thesis is about the experiences and motivations of nurses who left Malawi, and of those who stayed behind. Using a qualitative biographical method to examine their experiences along a timeline of key life events, I develop a comprehensive picture of nurse migration. The findings show that nurses’ decisions and experiences have been shaped by demographic and political shifts and by a strong culture of family. Population growth has increased competition for higher education and caused a palpable shift in motives for becoming a nurse. Prospective students now see nurse training as a means to a guaranteed career, or to a marketable qualification which can lead to alternative employment. Working conditions have not improved despite numerous government initiatives, and nurses are still leaving for greener pastures. Many now move to Malawian Non-Governmental Organisations, but before 2005 nurses were able to take advantage of the United Kingdom’s (UK) active recruitment strategy. Most were motivated by the prospect of educational opportunities and the financial survival of their families, who often encouraged them because of the status accorded to migration. Whilst nurses in the UK were pleased with their lifestyle improvements, they found it challenging to integrate into society and the workplace. Many also found it difficult to achieve their educational and financial goals, and the stigma of returning to Malawi empty-handed led them to extend their stay. The enduring high status of migration and its unparalleled benefits mean that the desire to migrate is still strong amongst nurses, and many believe that the recent decline in migration is attributable only to tighter UK immigration restrictions

Making a difference for children and families: an appreciative inquiry of health visitor values and why they start and stay in post

The study aimed to develop an understanding of health visitor recruitment and retention by examining what existing staff and new recruits wanted from their job, their professional aspirations and what would encourage them to start and stay in employment. Following a period of steady decline in numbers, the health visitor workforce in England has recently been invested in and expanded to deliver universal child public health. To capitalise on this large investment, managers need an understanding of factors influencing workforce retention and continuing recruitment of health visitors. The study was designed using an interpretive approach and involved students (n = 17) and qualified health visitors (n = 22) from the north and south of England. Appreciative inquiry (AI) exercises were used as methods of data collection during 2012. During AI exercises students and health visitors wrote about ‘a practice experience you have felt excited and motivated by and briefly describe the factors that contributed to this’. Participants were invited to discuss their written accounts of practice with a peer during an audio-recorded sharing session. Participants gave consent for written accounts and transcribed recordings to be used as study data, which was examined using framework analysis. In exploring personal meanings of health visiting, participants spoke about the common aspiration to make a difference to children and families. To achieve this, they expected their job to allow them to: connect with families; work with others; use their knowledge, skills and experience; use professional autonomy. The study offers new insights into health visitors’ aspirations, showing consistency with conceptual explanations of optimal professional practice. Psychological contract theory illustrates connections between professional aspirations and work commitment. Managers can use these findings as part of workforce recruitment and retention strategies and for building on the health visitor commitment to making a difference to children and families

What makes health visiting successful—or not? 2. The service journey

This is the second of two articles reporting evidence from a programme of research that focused on how health visiting works, including service user and workforce perspectives. Evidence and professional expertise indicate that a set of essential features enable health visitors to achieve the desired impact of improving child public health. These include organising services in a way that enables positive parent–health visitor relationships, continuity and co-ordination and the flexibility to use professional knowledge and autonomy in practice. Where service specifications give careful attention to this evidence, it is more likely that health visitors will be able to deliver a successful child health programme for the early years

Management versus site effects on the abundance of nitrifiers and denitrifiers in European mountain grasslands

It is well established that the abundances of nitrogen (N) transforming microbes are strongly influenced by land-use intensity in lowland grasslands. However, their responses to management change in less productive and less fertilized mountain grasslands are largely unknown. We studied eight mountain grasslands, positioned along gradients of management intensity in Austria, the UK, and France, which differed in their historical management trajectories. We measured the abundance of ammonia-oxidizing bacteria (AOB) and archaea (AOA) as well as nitrite-reducing bacteria using specific marker genes. We found that management affected the abundance of these microbial groups along each transect, though the specific responses differed between sites, due to different management histories and resulting variations in environmental parameters. In Austria, cessation of management caused an increase in nirK and nirS gene abundances. In the UK, intensification of grassland management led to 10-fold increases in the abundances of AOA and AOB and doubling of nirK gene abundance. In France, ploughing of previously mown grassland caused a 20-fold increase in AOA abundance. Across sites the abundance of AOB was most strongly related to soil NO3−-N availability, and AOA were favored by higher soil pH. Among the nitrite reducers, nirS abundance correlated most strongly with N parameters, such as soil NO3−-N, microbial N, leachate NH4+-N, while the abundance of nirK-denitrifiers was affected by soil total N, organic matter (SOM) and water content. We conclude that alteration of soil environmental conditions is the dominant mechanism by which land management practices influence the abundance of each group of ammonia oxidizers and nitrite reducers

Legacy effects of grassland management on soil carbon to depth

The importance of managing land to optimise carbon sequestration for climate change mitigation is widely recognised, with grasslands being identified as having the potential to sequester additional carbon. However, most soil carbon inventories only consider surface soils, and most large scale surveys group ecosystems into broad habitats without considering management intensity. Consequently, little is known about the quantity of deep soil carbon and its sensitivity to management. From a nationwide survey of grassland soils to 1 m depth, we show that carbon in grasslands soils is vulnerable to management and that these management effects can be detected to considerable depth down the soil profile, albeit at decreasing significance with depth. Carbon concentrations in soil decreased as management intensity increased, but greatest soil carbon stocks (accounting for bulk density differences), were at intermediate levels of management. Our study also highlights the considerable amounts of carbon in sub-surface soil below 30cm, which is missed by standard carbon inventories. We estimate grassland soil carbon in Great Britain to be 2097 Tg C to a depth of 1 m, with ~60% of this carbon being below 30cm. Total stocks of soil carbon (t ha-1) to 1 m depth were 10.7% greater at intermediate relative to intensive management, which equates to 10.1 t ha-1 in surface soils (0-30 cm), and 13.7 t ha-1 in soils from 30-100 cm depth. Our findings highlight the existence of substantial carbon stocks at depth in grassland soils that are sensitive to management. This is of high relevance globally, given the extent of land cover and large stocks of carbon held in temperate managed grasslands. Our findings have implications for the future management of grasslands for carbon storage and climate mitigation, and for global carbon models which do not currently account for changes in soil carbon to depth with management

Compared to conventional, ecological intensive management promotes beneficial proteolytic soil microbial communities for agro-ecosystem functioning under climate change-induced rain regimes

Projected climate change and rainfall variability will affect soil microbial communities, biogeochemical cycling and agriculture. Nitrogen (N) is the most limiting nutrient in agroecosystems and its cycling and availability is highly dependent on microbial driven processes. In agroecosystems, hydrolysis of organic nitrogen (N) is an important step in controlling soil N availability. We analyzed the effect of management (ecological intensive vs. conventional intensive) on N-cycling processes and involved microbial communities under climate change-induced rain regimes. Terrestrial model ecosystems originating from agroecosystems across Europe were subjected to four different rain regimes for 263 days. Using structural equation modelling we identified direct impacts of rain regimes on N-cycling processes, whereas N-related microbial communities were more resistant. In addition to rain regimes, management indirectly affected N-cycling processes via modifications of N-related microbial community composition. Ecological intensive management promoted a beneficial N-related microbial community composition involved in N-cycling processes under climate change-induced rain regimes. Exploratory analyses identified phosphorus-associated litter properties as possible drivers for the observed management effects on N-related microbial community composition. This work provides novel insights into mechanisms controlling agro-ecosystem functioning under climate change

Why health visiting? Examining the potential public health benefits from health visiting practice within a universal service: A narrative review of the literature

INTRODUCTION: There is increasing international interest in universal, health promoting services for pregnancy and the first three years of life and the concept of proportionate universalism. Drawing on a narrative review of literature, this paper explores mechanisms by which such services might contribute to health improvement and reducing health inequalities. OBJECTIVES: Through a narrative review of empirical literature, to identify: DESIGN: The paper draws upon a scoping study and narrative review. REVIEW METHODS: We used three complementary approaches to search the widely dispersed literature: Our key inclusion criterion was information about health visiting practice. We included empirical papers from United Kingdom (UK) from 2004 to February 2012 and older seminal papers identified in search (3), identifying a total of 348 papers for inclusion. A thematic content analysis compared the older (up to 2003) with more recent research (2004 onwards). RESULTS: The analysis revealed health visiting practice as potentially characterized by a particular 'orientation to practice.' This embodied the values, skills and attitudes needed to deliver universal health visiting services through salutogenesis (health creation), person-centredness (human valuing) and viewing the person in situation (human ecology). Research about health visiting actions focuses on home visiting, needs assessment and parent-health visitor relationships. The detailed description of health visitors' skills, attitudes, values, and their application in practice, provides an explanation of how universal provision can potentially help to promote health and shift the social gradient of health inequalities. CONCLUSIONS: Identification of needs across an undifferentiated, universal caseload, combined with an outreach style that enhances uptake of needed services and appropriate health or parenting information, creates opportunities for parents who may otherwise have remained unaware of, or unwilling to engage with such provision. There is a lack of evaluative research about health visiting practice, service organization or universal health visiting as potential mechanisms for promoting health and reducing health inequalities. This paper offers a potential foundation for such research in future
