The study of ethical perceptions of construction managers

Ethics is important for business, individual career and image of industry. However, construction companies do not show high ethical standards. Studying ethical perception of manages is a popular topic at generic level, in particular professions and on construction-related professionals, but there is lack of research on studying ethical perceptions of construction managers. The aim of this research is to study the ethical perceptions of construction managers and how do demographic factors influence it. The method for conducting this study is through questionnaire survey among the UK construction managers. Three hundred and seven questionnaires were distributed and ninety-three completed questionnaires are completed and returned. The construction managers who appear to pay most concern on ethics are male, at middle age, at middle position in their organisations, having more than 21 years experience and are educated up to at least at degree level. The results show that the construction managers found ‘producing falsifying reports,’ ‘over-claiming expenses’ and ‘having low level of personal honesty’ as the most unethical perceptions. The findings also show that the ethical perceptions of construction managers are different from other construction-related professionals such as surveyors and engineers.

An investigation of the differences in ethical perceptions among construction managers and their peers

Previous research on ethical perceptions of managers and their peers show a consistent result, managers think they have higher ethical standards than their peers. The aim of this paper is to study the ethical perceptions of construction managers and their peers. The method for conducting the study is through a questionnaire survey among UK construction managers. Three hundred and seven questionnaires were distributed; ninety-three completed questionnaires were completed and returned. The overall results show that the construction mangers believe they have higher ethical standards than their peers. The ethical perceptions which are exceptions to this are cooperation between firms to establish common prices is an unfair act and whistleblowing, the respondents think their peers have higher ethical standards on these two issues. The managers in the current and previous studies think they are more ethical than their peers on dealing with the issue such as having low level of personal honesty. The difference between the current and previous studies is that the construction mangers think they have much higher ethical standards than their peers on the issue providing trade secrets in order to exchange for personal benefits.

Development of a new best practice model for building projects

Time, cost and quality are the traditional determinants of project success. The level of client satisfaction is a newly defined measurement of project success. Often the satisfaction level of construction clients is not high. The reasons for this situation are twofold, firstly due to the temporary organizational structure of construction team and secondly, the inefficient construction process. The traditional procurement route, whilst still the most popular in the building sector, is probably subject to most criticism. The primary aim of this research is to develop a new best practice model for building projects. This will enable the client’s project manager to identify best practice under the traditional procurement route before the work is executed. Within this model, the sequence of construction activities, the responsibilities of the parties and the critical aspect of each phase of the project are identified. This model can then be utilized at both the design and/ or the construction stage in order to secure project success.

Development of construction best practice expert system

The performance level of construction industry in the UK is generally considered to be low. The reasons for this situation are twofold, firstly due to the temporary organisational structure of construction team and secondly the inefficient construction process. Previous research in this area has focused on developing a generic model to represent the construction process. It is necessary to develop a process model, which clearly identifies the roles and responsibilities of the major parties on the building team and identifies the key issues within the project cycle. The method for presenting this model is by using an expert system. The primary aim of this paper is to discuss the development of the CONstruction Best Practice System (CONBPS). The theoretical framework of CONBPS and the development and evaluation of the system will be described. The future research will also be discussed. Finally, the advantage of this model will be identified.

Review of nursing care for patients undergoing percutaneous coronary intervention: a patient journey approach

Aim.  To evaluate the existing literature to inform nursing management of people undergoing percutaneous coronary intervention. Background.  Percutaneous coronary intervention is an increasingly important revascularisation strategy in coronary heart disease management and can be an emergent, planned or rescue procedure. Nurses play a critical role in delivering care in both the independent and collaborative contexts of percutaneous coronary intervention management. Design.  Systematic review. Method.  The method of an integrative literature review, using the conceptual framework of the patient journey, was used to describe existing evidence and to determine important areas for future research. The electronic data bases CINAHL, Medline, Cochrane and the Joanna Briggs data bases were searched using terms including: (angioplasty, transulminal, percutaneous coronary), nursing care, postprocedure complications (haemorrhage, ecchymosis, haematoma), rehabilitation, emergency medical services (transportation of patients, triage). Results.  Despite the frequency of the procedure, there are limited data to inform nursing care for people undergoing percutaneous coronary intervention. Currently, there are no widely accessible nursing practice guidelines focusing on the nursing management in percutaneous coronary intervention. Findings of the review were summarised under the headings: Symptom recognition; Treatment decision; Peri-percutaneous coronary intervention care, describing the acute management and Postpercutaneous coronary intervention management identifying the discharge planning and secondary prevention phase. Conclusions.  Cardiovascular nurses need to engage in developing evidence to support guideline development. Developing consensus on nurse sensitive patient outcome indicators may enable benchmarking strategies and inform clinical trial design. Relevance to clinical practice.  To improve the care given to individuals undergoing percutaneous coronary intervention, it is important to base practice on high-level evidence. Where this is lacking, clinicians need to arrive at a consensus as to appropriate standards of practice while also engaging in developing evidence. This must be considered, however, from the central perspective of the patient and their family.

High genetic diversity is not essential for successful introduction

Some introduced populations thrive and evolve despite the presumed loss of diversity at introduction. We aimed to quantify the amount of genetic diversity retained at introduction in species that have shown evidence of adaptation to their introduced environments. Samples were taken from native and introduced ranges of Arctotheca populifolia and Petrorhagia nanteuilii. Using microsatellite data, we identified the source for each introduction, estimated genetic diversity in native and introduced populations and calculated the amount of diversity retained in introduced populations. These values were compared to those from a literature review of diversity in native, confamilial populations and to estimates of genetic diversity retained at introduction. Gene diversity in the native range of both species was significantly lower than for confamilials. We found that, on average, introduced populations showing evidence of adaptation to their new environments retained 81% of the genetic diversity from the native range. Introduced populations of P. nanteuilii had higher genetic diversity than found in the native source populations, whereas introduced populations of A. populifolia retained only 14% of its native diversity in one introduction and 1% in another. Our literature review has shown that most introductions demonstrating adaptive ability have lost diversity upon introduction. The two species studied here had exceptionally low native range genetic diversity. Further, the two introductions of A. populifolia represent the largest percentage loss of genetic diversity in a species showing evidence of substantial morphological change in the introduced range. While high genetic diversity may increase the likelihood of invasion success, the species examined here adapted to their new environments with very little neutral genetic diversity. This finding suggests that even introductions founded by small numbers of individuals have the potential to become invasive.

How do consumers co-create their experiences? An exploration in the heritage sector

Whilst the body of work around co-creation has grown, co-creation continues to be considered from a value perspective with key questions, such as what is actually being co-created, remaining unanswered. This article moves beyond value to experiences and explores co-creation of the consumption experience. The research examines the manifestations and antecedents of co-creation of the consumption experience from a consumer angle and presents a co-creation framework. Customer critic analysis with consumers from two exemplar heritage organisations is used to investigate co-creation. The findings illuminate three facets of co-creation: co- production, engagement, and personalisation. This paper addresses a gap in Service- Dominant Logic theory, arts/heritage, and broader marketing literature by distinguishing between co-creation of value and co-creation of the consumption experience and proposing a definitive conceptualisation of the latter. The proposed model progresses the co-creation discussion to an empirical level and provides a foundation for future research.

Aptamers as theranostic agents: modifications, serum stability and functionalisation

Aptamers, and the selection process known as Systematic Evolution of Ligands by Exponential Enrichment (SELEX) used to generate them, were first described more than twenty years ago. Since then, there have been numerous modifications to the selectionprocedures. This review discusses the use of modified bases as a means of enhancing serum stability and producing effective therapeutic tools, as well as functionalising these nucleic acids to be used as potential diagnostic agents.
