Theoretical development and social capital measurement

Chapter 4, by Sarah Hean and colleagues, highlights the importance of theory development in making the concept useful to the practice of public health. The authors present an innovative way of thinking about the different facets of social capital, describe the development of a survey instrument that attempts to make explicit the inputs and outputs of social capital and describe how these can be operationalised in a practice setting. The survey tool takes account of the dynamic nature of social capital and offers a useful way of evaluating community projects

Who works in the public sector? Evidence from the World Values Survey

Earlier single-country studies found a higher level of intrinsic motivation among public sector workers, compared to the private sector. Using data from the World Values Survey, covering 51 countries, we find a tendency for public sector workers to be more intrinsically motivated, but this is not a universal relationship: we also show that the level of government corruption (appropriately instrumented) explains some of the variation across countries. Consistent with earlier studies that find that selection accounts for differential motivation across sectors, we show that intrinsically-motivated workers are less likely to work in the public sector when corruption is higher.Intrinsic motivation, public sector, corruption

Visitadores domiciliares e saúde infantil na Inglaterra: avanços e desafios

There is increasing interest in the early years as a focus for reducing health inequalities as well as one that is important for the children themselves. This paper describes the introduction in England of Sure Start Local Programmes, which included home visiting within a community development approach, and an intensive home visiting programme, the Nurse-Family partnership, for disadvantaged teenage mothers. It reflects on changes and challenges in service provision to mothers and their pre-school children in England, explaining that a long tradition of home visiting was, paradoxically, reduced as attention focused on the newer initiatives. This is now being addressed, with attention to a range of evidence based programmes and a specific focus on heath visitor provision.Existe un creciente interés en los años tempranos de la infancia para reducir inequidades de salud, tratándose de algo de alto impacto para los propios niños. Este artículo describe la introducción en Inglaterra de los Sure Start Local Programmes (Programas Locales de Inicio Seguro), los cuales incluyen visitas domiciliarias insertas en una aproximación al desarrollo comunitario, y un programa intensivo de visitas, el Nurse-Family partnership (Asociación Enfermera-Familia), para madres adolescentes en situación desventajosa. Se reflexiona acerca de cambios y desafíos en provisión de atención a madres y sus hijos en edad preescolar en Inglaterra, explicando que una larga tradición en visitas domiciliarias fue reducida, paradójicamente, por enfocarse la atención en las iniciativas más actuales. Todo esto está siendo direccionado, atendiendo a una serie de programas basados en la evidencia y a un foco específico en la percepción del visitante de campo.Há um crescente interesse, nos últimos anos, objetivando reduzir as desigualdades na área da saúde, bem como uma desigualdade específica infantil. Este artigo descreve a introdução, na Inglaterra, de programas locais chamados Sure Start, que incluem visitação domiciliar, dentro de uma abordagem de desenvolvimento da comunidade, e um programa intensivo de visitas domiciliares, a parceria com a Nurse-Family, para mães adolescentes em condições desfavoráveis. Isso reflete nas mudanças e desafios da provisão de serviço as mães e filhos em idade pré-escolar, na Inglaterra, explicando que uma longa tradição de visitas domiciliares foi, paradoxalmente, reduzida, conforme a atenção concentrava-se em novas iniciativas. Isso está sendo, agora, tratado, atentando para uma variedade de evidências com base nos programas e com um foco específico na provisão de visitantes da área da saúde

The M-C-M' cycle and social capital.

Social capital has become a popular term over the past two decades amongst researchers, policy makers and practitioners from varied disciplines. This popularity, however, has resulted in a great deal of confusion over the nature and application of social capital in different contexts. This confusion has made it difficult to identify and measure social capital within the evaluation of specific social and health programmes, one of the aims of which may be to stimulate social capital. This paper identifies a theoretical model that seeks to capture the dynamic nature of social capital to assist in the development of research methods that will facilitate its measurement and exploration within such programmes. The model reported in the paper identifies the key components of social capital and expresses the relationship between those components in a dynamic system based on Marx's description of the process of capital (economic) exchanges expressed in the M-C-M' cycle. The M-C-M' cycle is the transformation of money (M) into commodities (C), and the change of commodities back again into money (M') of altered value. The emphasis within the paper is on the capital element of the concept and its transactional nature with the aim of avoiding the pitfall of attributing social capital in relation to social behaviours in isolation of context and interaction. Importantly, the paper seeks to distinguish the central elements of social capital from some of the antecedent factors and outcomes often attributed to and confused with social capital adding to the problem of providing valid measurement. The model is presented as the basis for the measurement of social capital within a transactional process involving the investment of social resources in a cyclical process, which may result in net gains or losses. This process is described as the R-C-R' cycle following Marx's model of economic capital, with the focus being on the transfer of social resources (R) rather than money (M). R represents an internal resource held by individuals, C the external resource or commodity they obtain from the network and the R' the internal resource of altered value. The possibilities of the model in assisting in the measurement of social capital specifically in assessing formal networks are explored

Model for Predicting the Performance of Planetary Suit Hip Bearing Designs

Designing a space suit is very complex and often requires difficult trade-offs between performance, cost, mass, and system complexity. During the development period of the suit numerous design iterations need to occur before the hardware meets human performance requirements. Using computer models early in the design phase of hardware development is advantageous, by allowing virtual prototyping to take place. A virtual design environment allows designers to think creatively, exhaust design possibilities, and study design impacts on suit and human performance. A model of the rigid components of the Mark III Technology Demonstrator Suit (planetary-type space suit) and a human manikin were created and tested in a virtual environment. The performance of the Mark III hip bearing model was first developed and evaluated virtually by comparing the differences in mobility performance between the nominal bearing configurations and modified bearing configurations. Suited human performance was then simulated with the model and compared to actual suited human performance data using the same bearing configurations. The Mark III hip bearing model was able to visually represent complex bearing rotations and the theoretical volumetric ranges of motion in three dimensions. The model was also able to predict suited human hip flexion and abduction maximums to within 10% of the actual suited human subject data, except for one modified bearing condition in hip flexion which was off by 24%. Differences between the model predictions and the human subject performance data were attributed to the lack of joint moment limits in the model, human subject fitting issues, and the limited suit experience of some of the subjects. The results demonstrate that modeling space suit rigid segments is a feasible design tool for evaluating and optimizing suited human performance. Keywords: space suit, design, modeling, performanc

Expert voices: is it time to lower the voting age to 16?

The question of whether the UK should lower the minimum voting age from 18 to 16 has been on the agenda recently, with Ed Miliband making it explicit Labour policy, and the SNP enfranchising 16 and 17 year olds to good effect during the Scottish independence referendum. As part of the LSE’s ‘Expert Voices’ series, Public Policy Group Digital Editor Cheryl Brumley commissioned Sarah Birch, Richard Berry, Philip Cowley, and Andrew Mycock to record a short monologue about their thoughts on the issue, and to answer the question ‘is it time for the UK to lower the voting age to 16?

Planetary Suit Hip Bearing Model for Predicting Design vs. Performance

Designing a planetary suit is very complex and often requires difficult trade-offs between performance, cost, mass, and system complexity. In order to verifying that new suit designs meet requirements, full prototypes must eventually be built and tested with human subjects. Using computer models early in the design phase of new hardware development can be advantageous, allowing virtual prototyping to take place. Having easily modifiable models of the suit hard sections may reduce the time it takes to make changes to the hardware designs and then to understand their impact on suit and human performance. A virtual design environment gives designers the ability to think outside the box and exhaust design possibilities before building and testing physical prototypes with human subjects. Reductions in prototyping and testing may eventually reduce development costs. This study is an attempt to develop computer models of the hard components of the suit with known physical characteristics, supplemented with human subject performance data. Objectives: The primary objective was to develop an articulating solid model of the Mark III hip bearings to be used for evaluating suit design performance of the hip joint. Methods: Solid models of a planetary prototype (Mark III) suit s hip bearings and brief section were reverse-engineered from the prototype. The performance of the models was then compared by evaluating the mobility performance differences between the nominal hardware configuration and hardware modifications. This was accomplished by gathering data from specific suited tasks. Subjects performed maximum flexion and abduction tasks while in a nominal suit bearing configuration and in three off-nominal configurations. Performance data for the hip were recorded using state-of-the-art motion capture technology. Results: The results demonstrate that solid models of planetary suit hard segments for use as a performance design tool is feasible. From a general trend perspective, the suited performance trends were comparable between the model and the suited subjects. With the three off-nominal bearing configurations compared to the nominal bearing configurations, human subjects showed decreases in hip flexion of 64%, 6%, and 13% and in hip abduction of 59%, 2%, and 20%. Likewise the solid model showed decreases in hip flexion of 58%, 1%, and 25% and in hip abduction of 56%, 0%, and 30%, under the same condition changes from the nominal configuration. Differences seen between the model predictions and the human subject performance data could be attributed to the model lacking dynamic elements and performing kinematic analysis only, the level of fit of the subjects with the suit, the levels of the subject s suit experience

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
