Stone-built heritage inventory and ‘performance in use’ condition assessment of stonework

An academic–industrial partnership was formed with the aim of constructing a natural stone database for Northern Ireland that could be used by the public and practitioners to understand both the characteristics of the stone used in construction across Northern Ireland and how it has performed in use, and, through a linked database of historical quarries, explore the potential for obtaining locally sourced replacement stone. The aims were to improve the level of conservation specification by those with a duty of care for historical structures, and to enhance the quality of the conservation work undertaken by archi- tects and contractors through their improved knowledge of stone and stone decay processes.

Linking response strategies adopted by construction firms during the 2007 economic recession to Porter’s generic strategies

The time period bridging the years 2007 to 2012 will be remembered as one characterised by dramatic changes in the Irish and UK construction industries. Construction companies witnessed unprecedented changes in the environment, namely the coincidence of a sharp economic downturn, the significant decline of public works, a reduction in lending, increased competition, and structural changes in the marketplace. Nevertheless, little has been documented on what response strategies construction companies adopt as a result of an economic recession. Based on four exploratory case studies, a taxonomy framework of the response strategies adopted by Irish and UK construction companies during the 2007 economic recession was developed relative to Porter’s (1980) generic strategies of cost leadership, differentiation, and focus. Porter’s model (1980) is a well known theoretical framework among business strategists and industrial economists worldwide. The analysis provides strong support for the adoption of cost leadership strategies as a means to surviving the 2007 economic recession. The case studies further suggest that cost control initiatives are one of the most important attributes in companies’ responses to the 2007 recession. The findings provide valuable assistance for construction contractors in developing effective strategies and thus reducing business failures during recessionary periods.

Factors Influencing the Implementation of Site Waste Management Plans on UK Projects of all sizes

The purpose of this research is to identify and assess the opportunities and challenges of implementing a Site Waste Management Plan (SWMP) on projects irrespective of size. In the UK, construction and demolition waste accounts for a third of all UK waste. There are a number of factors that influence the implementation of SWMPs. In order to identify and analyse these factors, 4 unstructured interviews were carried out and a sample of 56 participants completed a questionnaire survey. The scope of the study was limited to UK
construction industry professionals. The analysis revealed that more needs to be done if the industry is to meet government targets of reduction in construction related waste going to landfill. In addition, although SWMP may not yet be legally required on all construction projects, clients and contractors need to realise
the benefits to cut costs and implement best practice by adopting a SWMP. The benefits of implementing a SWMP will not only help to achieve this but also gain significant cost savings on projects and is also extremely beneficial to the environment. This study presents evidence that contractors need to do more to reduce waste and draws a clear link between waste reduction and the implementation of SWMPs. The findings are useful in the ongoing efforts to encourage the industry to find smarter, more efficient and less
damaging ways to operate

Genetic polymorphisms and kidney transplant outcomes

Purpose of review: Gene polymorphism studies are growing at a quasiexponential rate and aim to improve immediate and long-term outcomes in renal transplantation. This review highlights recent evidence and potential future directions for genetic research studies.

Recent findings: Studies are largely based on immunity, inflammation and pharmacogenetics, investigating mostly 'surrogate' outcomes with sometimes conflicting results. However, the last 12 months has also heralded the emergence of important genome-wide association studies on transplantation, more robust replicated multicentre analyses of candidate gene variants, meta-analyses, and an increasing interest in copy number variation and donor genetics.

Summary: These studies set the scene for further investigation, aiming to understand pathways of disease and biomarkers of risk, and are leading to a greater understanding of the biology of transplantation. Future studies will require focus on donor : recipient and gene : environment interactions, and an integrated approach of 'transplantomics' to evaluate long-term outcomes in multinational collaborations.

The Impact of the Recent Economic Recession on the NEC Contract in Northern Ireland: A Preliminary Study

In comparison to the rest of the United Kingdom (UK) the Northern Irish Construction Industry was disproportionately affected by the recent economic recession. During this period, use of the New Engineering Contract (NEC) has proliferated in the public sector, however no study has been undertaken to examine the impact of the recession on this contract in Northern Ireland. The aim of this paper is to explore NEC contract implementation in Northern Ireland and the impact of the recession on its operation. A qualitative methodology is adopted using a literature review and semi structured interviews with six construction professionals. A qualitative analysis identifies themes and issues arising exploring connections and links between them using thematic coding. The initial findings are that the introduction of the NEC contract in Northern Ireland makes demands of contractors and consultants in terms of additional resources and training. Some consultants show a clear lack of understanding of the contract and its provisions. Whilst there is general agreement that the contract does help to stimulate good project management, the interviewees find the contract time consuming and complicated to administer, describing it as “unforgiving for the architect and unforgiving to the contractor.” Due to the impact of the recession, both contractors and consultants are still reporting a drop in income from pre-recession levels. Project resourcing levels have dropped significantly since the onset of the recession. Adversarial and opportunistic behaviour has increased. Many consultants and contractors are struggling to adequately administer the NEC contract at current income levels. The introduction of the NEC contract and the economic recession have exerted opposing forces on the implementation of the contract, hindering its execution. As the pressures exerted by the economic recession abate and a greater understanding of the contract develops, these opposing forces will ease leading to a more consistent implementation of the contract.

Why Are Some Subsidiaries of Multinationals the Source of Novel Practices while Others Are Not? National, Corporate and Functional Influences

It has frequently been argued that multinational companies are moving towards network forms whereby subsidiaries share different practices with the rest of the company. This paper presents large-scale empirical evidence concerning the extent to which subsidiaries input novel practices into the rest of the multinational. We investigate this in the field of human resources through analysis of a unique international data set in four host countries - Canada, Ireland, Spain and the UK - and address the question of how we can explain variation between subsidiaries in terms of whether they initiate the diffusion of practices to other subsidiaries. The data support the argument that multiple, rather than single, factor explanations are required to more effectively understand the factors promoting or retarding the diffusion of human resource practices within multinational companies. It emerges that national, corporate and functional contexts all matter. More specifically, actors at subsidiary level who seek to initiate diffusion appear to be differentially placed according to their national context, their place within corporate structures and the extent to which the human resource function is internationally networked.

Incentive Mechanisms and Their Impact on Project Performance

Good performance characterizes project success and value for money. However, performance problems are not uncommon in project management. Incentivization is generally recognized as a strategy of addressing performance problems. This chapter aims to explore incentive mechanisms and their impact on project performance. It is mainly based on the use of incentives in construction and engineering projects. The same principles apply to project management in other industry sectors. Incentivization can be used in such performance areas as time, cost, quality, safety and environment. A client has different ways of incentivizing his contractor’s performance, e.g. (1) a single incentive or multiple incentives; and (2) incentives or disincentives or a combination of both. The establishment of incentive mechanisms proves to have a significant potential for relationship development, process enhancement and performance improvement. In order to ensure the success of incentive mechanisms, both contractors and clients need to make extra efforts. As a result, a link is developed among incentive mechanisms, project management system and project performance.

Oil and Dependency::The Case of Kazakhstan

Following the collapse of the Soviet Union in 1991, the newly independent oil-rich country of Kazakhstan has become a major recipient of foreign direct investment (FDI). Although international organisations such as the IMF and UNCTAD have claimed that FDI could be considered an engine in the transition from state socialism and as a powerful force for integration of this region into the global economy; this investment also poses significant risks to Kazakhstan. These risks fall into two broad categories: The first category can be broadly described as issues associated with the “resource curse” or the “Dutch Disease”. The term Dutch Disease describes a situation where booming demand in oil exporting countries, due to high oil revenues, leads to shift of an economy’s productive resources from the tradeable sector to the non-tradeable sector. The second category is associated with the over-dependency of oil exporting countries on a relatively small number of large multinational corporations (MNCs). This over-dependency can lead to a situation where licenses and concessions are granted at less favourable conditions than if they were auctioned in an efficient market. Examining the licensing policy of the Kazakhstani Energy and Mineral Resource Ministry, this paper notes that the latter issue of over-dependency has become less of a risk due to deliberate efforts to diversify investment relationships. Notwithstanding this situation there is some evidence that it remains difficult for oil exporting nations such as Kazakhstan to ensure that oil revenues are channelled into sustainable economic development.

Recycling of demolition waste in Merseyside

There have been considerable developments in Merseyside over the last fifteen years with regards to the commercialisation of recycled demolition aggregate. Liverpool is an urban region that at the time was undergoing regeneration. This required the demolition of old infrastructure. Subsequent reconstruction required new construction materials. A project started in 2001 to investigate the economics, practicalities and technicalities of using recycled demolition aggregates in concrete precast products. It was estimated that if all six demolition contractors around Liverpool worked round the clock (i.e. assuming there was enough feed material) they would still have found it difficult to maintain the required supplies for a single precast factory. Investment in equipment was therefore required to guarantee supply and improve the quality of the recycled demolition aggregate. The market forces and the incentives/drivers for construction companies to adopt sustainable practises have encouraged investment of several million pounds to be made in new recycling plants and has resulted in ‘urban quarries’. This paper describes the developments in recycling of construction and demolition waste over the last decade in Merseyside and shows that recycling is not only sustainable but also profitable.

Triggering employee voice under the European Information and Consultation Directive: A non-union case study

The transposition of the 2002/14/EC Directive, establishing a general framework for information and consultation (I&C), has proven contentious in largely voluntarist systems of employment regulation. Receiving particular criticism is the employee ‘opt-in’ mechanism as a means to access I&C rights. For non-union employees in particular, the ability and potential to negotiate rights for I&C is widely seen to be problematic. This article uniquely examines the opt-in mechanism in the context of non-unionism, considering how non-union employers respond to non-union employees invoking their legislative rights to I&C. Drawing upon a case study conducted over four years in a large non-union multinational, the evidence shows how the opt-in and negotiation process function to the advantage of the employer rather than the intended regulatory impact to advance employee rights

Identifying the relative importance of stock characteristics

There is no consensus in the literature as to which stock characteristic best explains returns. In this study, we employ a novel econometric approach better suited than the traditional characteristic sorting method to answer this question for the UK market. We evaluate the relative explanatory power of market, size, momentum, volatility, liquidity and book-to-market factors in a semiparametric characteristic-based factor model which does not require constructing characteristic portfolios. We find that momentum is the most important factor and liquidity is the least important based on their relative contribution to the fit of the model and the proportion of sample months for which factor returns are significant. Overall, this study provides strong evidence to support that the momentum characteristic can best explain stock returns in the UK market. The econometric approach employed in this study is a novel way to assess relevant investment risk in international financial markets outside U.S. Moreover, multinational institutions and investors can use this approach to identify regional factors in order to diversify their portfolios.

Seven key actions to eradicate rheumatic heart disease in Africa: the Addis Ababa communiqué

Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) remain major causes of heart failure, stroke and death among African women and children, despite being preventable and imminently treatable. From 21 to 22 February 2015, the Social Cluster of the Africa Union Commission (AUC) hosted a consultation with RHD experts convened by the Pan-African Society of Cardiology (PASCAR) in Addis Ababa, Ethiopia, to develop a 'roadmap' of key actions that need to be taken by governments to eliminate ARF and eradicate RHD in Africa. Seven priority areas for action were adopted: (1) create prospective disease registers at sentinel sites in affected countries to measure disease burden and track progress towards the reduction of mortality by 25% by the year 2025, (2) ensure an adequate supply of high-quality benzathine penicillin for the primary and secondary prevention of ARF/RHD, (3) improve access to reproductive health services for women with RHD and other non-communicable diseases (NCD), (4) decentralise technical expertise and technology for diagnosing and managing ARF and RHD (including ultrasound of the heart), (5) establish national and regional centres of excellence for essential cardiac surgery for the treatment of affected patients and training of cardiovascular practitioners of the future, (6) initiate national multi-sectoral RHD programmes within NCD control programmes of affected countries, and (7) foster international partnerships with multinational organisations for resource mobilisation, monitoring and evaluation of the programme to end RHD in Africa. This Addis Ababa communiqué has since been endorsed by African Union heads of state, and plans are underway to implement the roadmap in order to end ARF and RHD in Africa in our lifetime.

Similarity or Variation? Employee Representation and Consultation Approaches Amongst Liberal Market Economy Multinationals

This paper engages with the varieties of capitalism literature to investigate the employee representation and consultation approaches of liberal market economy multinational companies (MNCs), specifically Australian, British and US MNCs operating in Australia. While the literature would suggest commonality amongst these MNCs, the paper considers whether the evidence points to similarity or variation amongst liberal market headquartered MNCs. The findings contribute to filling a recognized empirical gap on MNC employment relations practice in Australia and to a better understanding of within category varieties of capitalism similarity and variation. Drawing on survey data from MNCs operating in Australia, the results demonstrated that UK-owned MNCs were the least likely to report collective structures of employee representation. Moreover, it was found that Australian MNCs were the most likely to engage in collective forms of employee representation and made less use of direct consultative mechanisms relative to their British and US counterparts. In spite of the concerted individualization of the employment relations domain over previous decades, Australian MNCs appear to have upheld more long-standing national institutional arrangements with respect to engaging with employees on a collective basis. This varies from British and US MNC approaches which denotes that our results display within category deviation in the variety of capitalism liberal market economy typology. Just as Hall and Soskice described their seminal work on liberal market economy (LME) and coordinated market economy (CME) categories as a “work-in-progress” (2001: 2), we too suggest that Australia’s evolution in the LME category, and more specifically its industrial relations system development, and the consequences for employment relations practices of its domestic MNCs, may be a work-in-progress.

Análise do comportamento de polímeros na estabilização de solos em fundações

O presente projeto de investigação em Engenharia Civil é construído em torno das necessidades atuais expressas pelos setores da construção e obras públicas em fundações. Em colaboração com a empresa GEO este trabalho pretende dar resposta em tempo útil aos empreiteiros, pondo o conhecimento científico ao serviço da indústria, colmatando a escassez de investigação académica que se verifica neste domínio. Esta investigação, à qual se associou a empresa BRASFOND, recorre ao estudo de ensaios de carga estática à compressão realizados no Brasil, segundo a NBR 12131 (2005) e NBR 12131 (2006). Assim, para estudar o desempenho de polímeros aplicados na estabilização de solos em fundações, foram analisados 6 ensaios de carga realizados em obras de intervenção da empresa GEO, disponibilizados pela empresa BRASFOND. Os ensaios de carga verticais estáticos de compressão axial foram realizados em estacas de 3 obras, nomeadamente a construção de uma central termoelétrica, em 2009, e de dois edifícios, em 2010. O projeto de fundações da central termoelétrica assentou na execução de estacas com polímeros, com 1270 estacas moldadas “in loco” com 1 000 mm de diâmetro e profundidade variável de 10 m a 18 m, em solos moles e pouco compactos de 8 m a 9 m de espessura, encastradas até 3 m sobre um maciço Gnaisse medianamente alterado (W3). Dos ensaios de carga realizados nesta obra, foram alvo deste estudo a análise dos primeiros 4 disponibilizados pela empresa. Os valores estimados por métodos semi-empíricos da capacidade resistente das estacas, considerando a recuperação da rocha nos trechos encastrados, foram comparados com a carga resistente última à compressão obtida através do ensaio de carga. O projeto de fundações de dois edifícios de elevado número de andares (cerca de 30) no litoral do Estado de São Paulo, em Santos, assentou na execução de fundações indiretas em solos moles a muito moles, com estacas de grandes dimensões moldadas com recurso a polímeros. Para atestar a qualidade das estacas, de forma a avaliar o comportamento carga versus assentamento e estimar as características da capacidade de carga, procedeu-se à execução de dois ensaios de carga estática à compressão, um dos quais instrumentado em profundidade. Os valores estimados por métodos semi-empíricos da capacidade resistente das estacas foram comparados com a carga resistente última à compressão obtida através do ensaio de carga. Para além deste estudo se revestir de interesse académico e empresarial, o contexto inerente à aplicação de polímeros em fundações é relevante para a prática pedagógica. Assim, este projeto envolve também uma componente educacional, esta última implementada numa escola do ensino básico e secundário da região centro do país.

A value chain analysis of tuna industry in Ghana

Every can of tuna purchased by the consumer has taken a long journey before reaching the supermarket shelves. For each can bought there is a lengthy process from sea to shelf. A large proportion of the tuna cans purchased in the European Union come all the way from West Africa; a developing region with a high dependency on fisheries. Amidst an ever-increasing demand for tuna products the global tuna fisheries are set to continue expanding, apparently one of the last natural resource based industries fit to do so in West Africa. Tuna is the biggest fisheries export and dominates the fisheries sector in Ghana, a country situated in West Africa. This thesis aims to understand how this globally important industrial fisheries functions in terms of procedures, practices, Governance and finance. Socioeconomic influences, in the setting of a developing country, were also examined. For these purposes a Value Chain Analysis was employed. A Value Chain Analysis is a tool commonly used to understand how different companies and organizations participate in a domestic policy environment, which directs conclusion in the global economy. This analysis has the potential to allow researchers to fully understand a commodity chain and hence identify realistic opportunities for consequential improvements. Interviews and questionnaires were employed in-field Ghana along with secondary data collection techniques. It was found that the fisheries functions at the production level under influences from large multinational companies and tends to operate with a certain degree of lawlessness. Governance over the value chain is well defined, however implementation is poor or non-existent. The processors, whom are also dominated by multinationals, exert some control over the producers and their sales, however the high value links which are highlighted occur at the retail stage. Socioeconomic dynamics acting in the chain included the lack of communication between the public and private sector, power imbalances amongst players at production, the role of local businesswomen as actors in the chain and the general characteristics of the workers in the industry. Value addition and upgrading are needed the most in Governance over the chain, especially within Monitoring, Control and Surveillance. The results of the study provide a wealth of material about the components of a cost-heavy fishing industry in a developing country; an industry on which many eyes have recently turned due to illegal fishing activities. It highlights clearly where funding and future focus are needed. This value chain can be used as a guide for those that need to comprehend the financial complexities and real life dynamics of the Ghanaian tuna fishing industry today.
