Professionalism in digitally-mediated project work

Fieldwork in a major construction programme is used to examine what is meant by professionalism where large integrated digital systems are used to design, deliver, and maintain buildings and infrastructure. The increasing ‘professionalization’ of the client is found to change other professional roles and interactions in project delivery. New technologies for approvals and workflow monitoring are associated with new occupational groups; new kinds of professional accountability; and a greater integration across professional roles. Further conflicts also arise, where occupational groups have different understandings of project deliverables and how they are competently achieved. The preliminary findings are important for an increasing policy focus on shareable data, in order for building owners and operators to improve the cost, value, handover and operation of complex buildings. However, it will also have an impact on wider public decision-making processes, professional autonomy, expertise and interdependence. These findings are considered in relation to extant literatures, which problematize the idea of professionalism; and the shift from drawings to shareable data as deliverables. The implications for ethics in established professions and other occupational groups are discussed; directions are suggested for further scholarship on professionalism in digitally mediated project work to improve practices which will better serve society.

Integrating Sustainability into Brownfield Regeneration: Rhetoric or Reality? – An Analysis of the UK Development Industry

In the UK and elsewhere the use of the term ‘sustainable brownfield regeneration’ has resulted from the interweaving of two key policy themes, comprising ‘sustainable development’ and ‘brownfield regeneration’. This paper provides a critical overview of brownfield policy within the context of the emerging sustainable development agenda in the UK, and examines the development industry's role and attitudes towards key aspects of sustainable development and brownfield regeneration. The paper analyses results from a survey of commercial and residential developers carried out in mid‐2004, underpinned by structured interviews with eleven developers in 2004–2005, which form part of a two‐and‐half‐year EPSRC‐funded project. The results suggest that despite the increasing focus on sustainability in government policy, the development industry seems ill at ease with precisely how sustainable development can be implemented in brownfield schemes. These and other findings, relating to sustainability issues (including the impact of climate change on future brownfield development), have important ramifications for brownfield regeneration policy in the UK. In particular, the research highlights the need for better metrics and benchmarks to be developed to measure ‘sustainable brownfield regeneration’. There also needs to be greater awareness and understanding of alternative clean‐up technologies to ‘dig and dump’.

Executive project management structure and the challenges acing its adoption in the Nigerian construction industry

Project management (PM) is a globally recognized discipline and has been widely adopted within the construction industry. Despite advancements in the PM discipline, the ineffective traditional management system, typical of the non-executive PM structure, is still widely used in the Nigerian construction industry. The aim of this paper is thus to explore the challenges facing the adoption of the executive PM structure in Nigeria. The paper first assesses the level of growth of PM in Nigeria using UK best practices as a benchmark and identifies the key PM characteristics in the two countries. Focus group interviews were used to collect the primary data for the study and content analysis was used to present the results in a thematic format. The study revealed the key barriers to the adoption of an executive PM structure in Nigeria as a lack of proper awareness, unfavorable policies, skill shortages, the traditional culture of stakeholders and the absence of a regulatory body. It is recommended that the government, as a major player/client in the Nigerian construction industry, should lead the campaign to change the traditional industry approach to project management. This is necessary if construction stakeholders in Nigeria are to be educated and encouraged towards adopting and putting into practice effective PM.

Effects of Low-Level Laser Therapy (LLLT) in the Development of Exercise-Induced Skeletal Muscle Fatigue and Changes in Biochemical Markers Related to Postexercise Recovery

STUDY DESIGN: Randomized crossover double-blinded placebo-controlled trial. OBJECTIVE: To investigate if low-level laser therapy (LLLT) can affect biceps muscle performance, fatigue development, and biochemical markers of postexercise recovery. BACKGROUND: Cell and animal studies have suggested that LLLT can reduce oxidative stress and inflammatory responses in muscle tissue. But it remains uncertain whether these findings can translate into humans in sport and exercise situations. METHODS: Nine healthy male volleyball players participated in the study. They received either active LLLT (cluster probe with 5 laser diodes; A = 810 nm; 200 mW power output; 30 seconds of irradiation, applied in 2 locations over the biceps of the nondominant arm; 60 J of total energy) or placebo LLLT using an identical cluster probe. The intervention or placebo were applied 3 minutes before the performance of exercise. All subjects performed voluntary elbow flexion repetitions with a workload of 75% of their maximal voluntary contraction force until exhaustion. RESULTS: Active LLLT increased the number of repetitions by 14.5% (mean +/- SD, 39.6 +/- 4.3 versus 34.6 +/- 5.6; P = .037) and the elapsed time before exhaustion by 8.0% (P = .034), when compared to the placebo treatment. The biochemical markers also indicated that recovery may be positively affected by LLLT, as indicated by postexercise blood lactate levels (P<.01), creatine kinase activity (P = .017), and C-reactive protein levels (P = .047), showing a faster recovery with LLLT application prior to the exercise. CONCLUSION: We conclude that pre-exercise irradiation of the biceps with an LLLT dose of 6 J per application location, applied in 2 locations, increased endurance for repeated elbow flexion against resistance and decreased postexercise levels of blood lactate, creatine kinase, and C-reactive protein. LEVEL OF EVIDENCE: Performance enhancement, level 1b. J Orthop Sports Phys Ther 2010;40(8):524-532. doi:10.2519/jospt.2010.3294

Gestão estratégica da informação como fator condicionante para a definição e implementação de políticas de defesa e segurança nacional no contexto da Amazônia Legal: o caso SIPAM/SIVAM

The objective of this work is the study of the existing correlations between the strategical use of the information and the joint and implementation of defense politics and national security in the Legal Amazonian. For in such a way, the proposal was developed from the analysis of the systems of protection and monitoring of the Amazonian (SIPAM/SIVAM), where we search to inquire as these systems have contributed for the definition and implantation of these politics. For the Amazonian, with its natural wealth, threats and vulnerabilities, the perspectives of integration, security and national defense and of sustainable development constitute great challenges to be faced, where the efficient use of the technology is a basic reference that must be incorporated in the strategies and public politics in these areas. One is about a strategical project, conceived with vision of future, protection and development of the . The objective SIPAM/SIVAM the defense and the guarantee of the Brazilian sovereignty in the Legal Amazonian, beyond the systematization and accomplishment of the governmental actions in the region, by means of the intensive use of technological apparatus. In turn, they reflect the priority that the Amazon region has in terms of defense and security for the Country, and symbolize the strategy of the State to protect it. The SIPAM/SIVAM if finds in a boarding line in which the guarantee of the national sovereignty also involves the care with the development of the local population, inside of a proposal educative and integrator. Like conclusion we affirm that of the SIPAM/SIVAM creates a new paradigm for the public administration, where the organizations work with a shared set of information, beyond starting to act of integrated form. Thus, when searching permanently the rationalization of efforts and resources, trying an unknown form of institution relationship where infrastructure and products are shared, the SIPAM/SIVAM creates a new premise for the Brazilian public administration and contributes to give a new direction to the development of the Amazonian.

Gestão da inovação para a sustentabilidade ambiental: estudos de caso do desenvolvimento e difusão de produtos de consumo industrializados com materiais de fontes renováveis

O objetivo desta tese é identificar como ocorre a gestão da inovação de produto ambientalmente sustentável. Pelo método de estudo de caso e sob a perspectiva de três vertentes da teoria organizacional (estrutura do setor de negócios, visão baseada em recursos e visão relacional) foi realizada uma análise abrangente de como os condicionantes externos do ambiente competitivo, os condicionantes internos empresariais e os relacionamentos organizacionais impactaram no projeto de desenvolvimento e difusão de duas inovações de produto com atributos favoráveis à sustentabilidade ambiental: uma esponja de banho com fibras amazônicas e PET reciclado e um lava-louças líquido para o pronto-uso de fontes renováveis. Os dois casos apresentam marcantes diferenças em relação ao porte das empresas, às estruturas, competências e culturas organizacionais, à maturidade das respectivas plataformas tecnológicas de fontes renováveis e às abordagens utilizadas na gestão dos projetos de desenvolvimento de novo produto. Além disso, os dois casos são distintos na competitividade dos atributos de produto ambientais e funcionais em relação ao preço ante os produtos concorrentes. Apesar destas diferenças, construtos da visão relacional foram utilizados para identificar similaridades entre os dois estudos de caso na gestão da inovação. Redes informais internas realizaram uma inovação organizacional ao criarem um departamento de sustentabilidade, o qual realizou diagnósticos e recomendações para minimizar os riscos sócio-ambientais e regulatórios decorrentes do suprimento da fibra amazônica para a esponja de banho. E um relacionamento colaborativo complementou a inovação de produto e realizou inovações de marketing que proporcionaram o melhor desempenho na difusão do lava-louças pronto-uso de fontes renováveis no varejo. Portanto, apesar das diferenças nos condicionantes internos e externos, a gestão da inovação nos dois casos se utilizou de relacionamentos colaborativos a fim de gerar inovações empresariais que solucionaram as restrições ao processo de inovação de produto ambientalmente sustentável.
