Identifying solutions to increase participation in physical activity interventions within a socio-economically disadvantaged community: a qualitative study

Background: There is an urgent need to increase population levels of physical activity, particularly amongst those who are socio-economically disadvantaged. Multiple factors influence physical activity behaviour but the generalisability of current evidence to such ‘hard-to-reach’ population subgroups is limited by difficulties in recruiting them into studies. Also, rigorous qualitative studies of lay perceptions and perceptions of community leaders about public health efforts to increase physical activity are sparse. We sought to explore, within a socio-economically disadvantaged community, residents’ and community leaders’ perceptions of physical activity (PA) interventions and issues regarding their implementation, in order to improve understanding of needs, expectations, and social/environmental factors relevant to future interventions.

Methods: Within an ongoing regeneration project (Connswater Community Greenway), in a socio-economically disadvantaged community in Belfast, we collaborated with a Community Development Agency to purposively sample leaders from public- and voluntary-sector community groups and residents. Individual semi-structured interviews were conducted with 12 leaders. Residents (n=113), of both genders and a range of ages (14 to 86 years) participated in focus groups (n=14) in local facilities. Interviews and focus groups were recorded, transcribed verbatim and analysed using a thematic framework.

Results: Three main themes were identified: awareness of PA interventions; factors contributing to intervention effectiveness; and barriers to participation in PA interventions. Participants reported awareness only of interventions in which they were involved directly, highlighting a need for better communications, both inter- and intra-sectoral, and with residents. Meaningful engagement of residents in planning/organisation, tailoring to local context, supporting volunteers, providing relevant resources and an ‘exit strategy’ were perceived as important factors related to intervention effectiveness. Negative attitudes such as apathy, disappointing experiences, information with no perceived personal relevance and limited access to facilities were barriers to people participating in interventions.

Conclusions: These findings illustrate the complexity of influences on a community’s participation in PA interventions and support a social-ecological approach to promoting PA. They highlight the need for cross-sector working, effective information exchange, involving residents in bottom-up planning and providing adequate financial and social support. An in-depth understanding of a target population’s perspectives is of key importance in translating PA behaviour change theories into practice.

Collaborative evolution: the context surrounding the formation and the effectiveness of a school partnership in a divided community in Northern Ireland

This paper examines an initiative promoting collaboration between schools located in a city setting in Northern Ireland, which is broadly divided along ethnic and political lines. The schools involved, like the vast majority of schools in Northern Ireland, educate Protestant and Catholic children separately. This presents particular challenges for school collaboration as it implies the establishment of new, connected relationships in an education system, which is historically and contemporaneously more characterised by division. Since 2007, the schools in this study have been involved in an education initiative which promotes cross-sectoral shared learning in core areas of the curriculum with a view to promoting school improvement; the additional, indirect goal is also about improving community relations. However, over this period, the relationship between the institutions has deepened, leading schools to examine how they can sustain partnership and evolve collaborative practice. This paper explores how the partnership has evolved and assesses its effectiveness as a collaborative enterprise. The paper concludes by demonstrating how effective collaboration between schools in Northern Ireland mitigates the potentially negative impacts of educating children separately, but also how effective models of school collaboration are capable of providing enhanced learning opportunities for pupils and are also capable of developing the communities in which they are located.

Integrated care pathways for airway diseases (AIRWAYS-ICPs)

The objective of Integrated Care Pathways for Airway Diseases (AIRWAYS-ICPs) is to launch a collaboration to develop multi-sectoral care pathways for chronic respiratory diseases in European countries and regions. AIRWAYS-ICPs has strategic relevance to the European Union Health Strategy and will add value to existing public health knowledge by: 1) proposing a common framework of care pathways for chronic respiratory diseases, which will facilitate comparability and trans-national initiatives; 2) informing cost-effective policy development, strengthening in particular those on smoking and environmental exposure; 3) aiding risk stratification in chronic disease patients, using a common strategy; 4) having a significant impact on the health of citizens in the short term (reduction of morbidity, improvement of education in children and of work in adults) and in the long-term (healthy ageing); 5) proposing a common simulation tool to assist physicians; and 6) ultimately reducing the healthcare burden (emergency visits, avoidable hospitalisations, disability and costs) while improving quality of life. In the longer term, the incidence of disease may be reduced by innovative prevention strategies. AIRWAYSICPs was initiated by Area 5 of the Action Plan B3 of the European Innovation Partnership on Active and Healthy Ageing. All stakeholders are involved (health and social care, patients, and policy makers).

On Regression Methods for Virtual Metrology in Semiconductor Manufacturing

Virtual metrology (VM) aims to predict metrology values using sensor data from production equipment and physical metrology values of preceding samples. VM is a promising technology for the semiconductor manufacturing industry as it can reduce the frequency of in-line metrology operations and provide supportive information for other operations such as fault detection, predictive maintenance and run-to-run control. The prediction models for VM can be from a large variety of linear and nonlinear regression methods and the selection of a proper regression method for a specific VM problem is not straightforward, especially when the candidate predictor set is of high dimension, correlated and noisy. Using process data from a benchmark semiconductor manufacturing process, this paper evaluates the performance of four typical regression methods for VM: multiple linear regression (MLR), least absolute shrinkage and selection operator (LASSO), neural networks (NN) and Gaussian process regression (GPR). It is observed that GPR performs the best among the four methods and that, remarkably, the performance of linear regression approaches that of GPR as the subset of selected input variables is increased. The observed competitiveness of high-dimensional linear regression models, which does not hold true in general, is explained in the context of extreme learning machines and functional link neural networks.

Technological Learning in Developing Countries

Technological learning refers to the learning processes involved in improving the productive capabilities of an enterprise, sector or economy to enable it to produce higher quality goods or services with increasing levels of efficiency. Approaches to the study of technological learning include case studies of particular countries, sectors and firms; measures of export sophistication; and composite indicators of innovation and competitiveness. The present review draws on these approaches to provide an overview of the policies and practices that have been successful in different regions (East-Asia and Latin America) ; contexts (import substitution and liberalization) ; sectors (pulp and paper, IT services, electronics and passenger cars); and firms (Embrear and Lenovo). While it is clear that there is strong complementarity between domestic technological capability and the ability to absorb foreign technology, there is no simple policy recipe which is appropriate for all times, industries or places. Technological learning builds on and is shaped by what is already known. It requires time, space and resources all of which are influenced by the wider domestic and international context. The current international context is challenging but countries and firms have to find ways of moving forward despite the limited strategy space.

Critical Nodes In Directed Networks

Critical nodes—or “middlemen”—have an essential place in both social and economic networks when considering the flow of information and trade. This paper extends the concept of critical nodes to directed networks and in doing so identify strong and weak middlemen.
Node contestability is introduced as a form of competition in networks; a duality between uncontested intermediaries and middlemen is established. The brokerage power of middlemen is formally expressed and a general algorithm is constructed to measure the brokerage power of each node from the networks adjacency matrix. Augmentations of the brokerage power measure are discussed to encapsulate relevant centrality measures. Furthermore, we extend these notions and provide measures of the competitiveness of a network.
We use these concepts to identify and measure middlemen in two empirical socio-economic networks, the elite marriage network of Renaissance Florence and Krackhardt’s advice net- work.

Trade union responses to ageing workforces in the UK and Germany

Ageing workforces are placing conflicting pressures on European trade unions in order to, on the one hand, protect pensions and early retirement routes, and, on the other, promote human resource management (HRM) policies geared towards enabling their older members to extend working life. Using interviews from German and United Kingdom (UK) trade unions, we discuss how unions are both constrained and enabled by pre-existing institutional structures in advocating approaches to age management. In Germany, some unions use their strong institutional role to affect public policy and industrial change at national and sectoral levels. UK unions have taken a more defensive approach, focused on protecting pension rights. The contrasting varieties of capitalism, welfare systems and trade unions’ own orientations are creating different pressures and
mechanisms to which unions need to respond. While the German inclusive system is providing unions with mechanisms for negotiating collectively at the national level, UK unions’ activism remains localized.

Rationale for and implementation of age-neutral HRM in divergent institutional contexts–examples from Britain and Germany

Owing to demographic change as well as international and national pressures,
organisations will have to abandon oftentimes prevalent youth-centric HRM practices in favour of age-neutral HRM that is inclusive of the entire workforce, regardless of age. In order to do so, organisations turn to ‘best practice’ guides. These, however, do not tend to differentiate recommendations by country and/or sector. Based on research in eight case study organisations in the chemical, steel and retail sectors as well as in public schools in Germany and Britain, this chapter argues that the rationale for and the implementation of age-neutral HRM practices differ by national institutional and sectoral context as well as by the relative influence of social partners. Hence, organisations planning to implement age-neutral HRM should take organisational, institutional and sectoral peculiarities into account when doing so.

Review of the area planning process (a)

The area planning process continues and formal recommendations arising from it are now being brought forward as development proposals to amalgamate or close schools. At this point in the process the Education Committee requested some comment on five different aspects of the process: the impact of Area Planning to date; the validity of the surplus school vacancy calculation methodology; the Annual Area Profile information; the Needs Model (including as appropriate the implications of the Drumragh judgement); possible enhancements to the consultation and communication process;the facilitation of alternative cross-sectoral or cross-border solutions. This paper offers high level comment on each of these issues. In addition, the Education Committee facilitated a stakeholder consultation meeting in Parliament Buildings on 4 February, 2015. The broad themes that emerged in that discussion will also be mentioned in this paper.

Managerial Representations of Achieving Competitive Advantage in Architectural Firms within the United Kingdom

Purpose - The purpose is to unearth managerial representations of achieving competitive advantage in relation to architectural firms operating within the United Kingdom (UK).
Design/Methodology/Approach - A sequential qualitative methodology is applied, underpinned by nine managerial interviews in five architectural practices; all of which are analysed using computer assisted qualitative data analysis software.
Findings - 108 representations are identified with highly rated concepts discussed in detail. Subsequently, the leading concepts include reputation, client satisfaction, fees and staff resources, among others.
Research Limitations/Implications - There are numerous studies conducted on this subject; however, there has been no research done to date documenting managerial representations within the UK on achieving competitive advantage in the context of architectural firms.
Practical Implications – The need for architectural firms to develop a competitive advantage within their market sector is ever more apparent, particularly during times of increased competitiveness.
Originality/Value – This paper fulfils a gap in knowledge by contributing to underlying research on the subject of competitive advantage, but focusing on the managerial representations, specifically within UK practices. The findings are of relevance to architects in both the UK and beyond, as well as perhaps forming the basis of identifying further research with the area.

Cell Coverage Optimization for the Multicell Massive MIMO Uplink

We investigate the cell coverage optimization problem for the massive multiple-input multiple-output (MIMO) uplink. By deploying tilt-adjustable antenna arrays at the base stations, cell coverage optimization can become a promising technique which is able to strike a compromise between covering cell-edge users and pilot contamination suppression. We formulate a detailed description of this optimization problem by maximizing the cell throughput, which is shown to be mainly determined by the user distribution within several key geometrical regions. Then, the formulated problem is applied to different example scenarios: for a network with hexagonal shaped cells and uniformly distributed users, we derive an analytical lower bound of the ergodic throughput in the objective cell, based on which, it is shown that the optimal choice for the cell coverage should ensure that the coverage of different cells does not overlap; for a more generic network with sectoral shaped cells and non-uniformly distributed users, we propose an analytical approximation of the ergodic throughput. After that, a practical coverage optimization algorithm is proposed, where the optimal solution can be easily obtained through a simple one-dimensional line searching within a confined searching region. Our numerical results show that the proposed coverage optimization method is able to greatly increase the system throughput in macrocells for the massive MIMO uplink transmission, compared with the traditional schemes where the cell coverage is fixed.

Delivering a Research-Enabled Multistakeholder Partnership for Enhanced Patient Care at a Population Level: The Northern Ireland Comprehensive Cancer Program

The last 20 years have seen significant advances in cancer care in Northern Ireland, leading to measureable improvements in patient outcomes. Crucial to this transformation has been an ethos that recognizes the primacy role of research in effecting heath care change. The authors' model of a cross-sectoral partnership that unites patients, scientists, health care professionals, hospital trusts, bioindustry, and government agencies can be truly transformative, empowering tripartite clinical-academic-industry efforts that have already yielded significant benefit and will continue to inform strategy and its implementation going forward.

Reproductive success of parasitized males in a marine reef fish

Parasitism is hypothesized to reduce reproductive success in heavily parasitized males because females
may preferentially mate with less parasitized males (parasite-mediated sexual selection) or parasites may compromise
male competitiveness. In marine systems, this hypothesis is largely unexplored. This paper provides the first confirmed record of a copepod ectoparasite (Caligus buechlerae Hewitt 1964) on the common triplefin (Forsterygion lapillum) and evaluates the hypothesis that males parasitized with C. buechlerae experience lower reproductive success than unparasitized males (as determined
by the presence and area of eggs within male nests). We found that 38 % of males we surveyed were infected with
at least one C. buechlerae, with a median of two individuals per infected male. About 32 % of males were defending
eggs, with 62.5 % of those males infected with at least one parasite. Males of greater total length (TL) were both
more likely to be infected and more likely to be defending eggs. However, when statistically accounting for the effects
of TL, parasite infection had no effect on the probability of defending eggs, or the average surface area of eggs when
present. Positive covariation in fish length, the presence of eggs and parasite infection observed here potentially suggest
that the importance of parasitic infection on reproductive success may depend upon the strength of selection for larger male body size. Our study is one of the few studies to investigate the effects of ectoparasites on reproductive success in reef fish and also provides a quantitative measure of infection for a widespread species within New Zealand.
