This study assesses the level at which organizational and practitioner knowledge of BIM is currently positioned. The UK government, being the largest public stakeholder client, has realized the benefits and advantages of BIM when used in procuring projects across their lifecycle in the built environment. A critical review of the BIM literature was carried out and the evidence base was created in relation to government targets for 2016. At the current stage, Level 2 BIM adoption is achievable by 2016 for large construction firms but not for SMEs (small medium enterprise). Also, from evidence in this study, the technology needs to be properly tailored to meet SME variables if Level 2 status is to be achieved for the entire industry.展开更多

The theoret...Fiscal decentralization in Brazil has promoted a break in the national collection system and granted greater autonomy to states and municipalities against the federal government with regard to fundraising. The theoretical difference emerged, when one observes the greatest proliferation of local entities from the autonomy granted by the Federal Constitution (FC) from 1988 to the various levels of government, many of which almost totally depend on inter-governmental transfers. There are those who advocate the strengthening of public actions from observing the problems of small units (municipalities) and who will now have greater decision-making freedom. Therefore, this article aims to analyze the public finances of municipalities in the core theoretical (all people born in Espirito Santo) state guided by the Fiscal Responsibility Law (FRL) and fiscal decentralization in the country. For this purpose, they were taken as the time frame 2001 and 2009. Methodologically, this paper used a literature review, as well as data from the National Treasury Secretariat (STN). In addition, authors took as a tool to help multiple regression models to strengthen the results. The principal evidence shows that, even with a slight improvement in the framework of indicators of revenue, these municipalities have proved essentially dependent on resources from the Union. Additionally, the results show a relative reduction of spending on items, such as staff costs and legislation in one year to another. In parallel, there were greater participation of the variables, costs of health and sanitation, education and culture, among others, to explain the variation of the expenditure of municipalities in Espirito Santo in the years observed. The data fit well to the model with a significance level of 1%.展开更多

In this paper, we propose an approach named First and Others (F&O) counting. By introducing a tuning parameter a and a weight β, two new properties are obtained: (1) flexible assignment of credits by modifying the formula (with the change of a) and applying preference to the individual author by adjusting the weights (with the change ofβ), and (2) calculation of the credits by separating the formula for the first author from others. With formula separation, the credit of the second author shows an inflection point according to the change ofa. The developed theorems and proofs concerning the modification of a and fl reveal new properties and complement the base theory for informetrics. The F&O schema is also adapted when considering the policy of'first-corresponding-author-emphasis'. Through a comparative analysis using a set of empirical data from the fields of chemistry, medicine, psychology, and the Harvard survey data, the performance of the F&O approach is compared with those of other methods to demonstrate its benefits by the criteria of lack of fit and coefficient of determination.展开更多

It is difficult to diagnose and treat. We reported a typical case which was confirmed by physical examination and MR images. Ligamentous insufficiency was confirmed under direct vision, and was reconstructed with triceps fascia as described by Gong et al with slight modification. Regain of full function was achieved one year after surgery.展开更多

Increased cases of human infection with R. equi have been reported, especially in immunocompromised patients, within recent years. We present a case of R. equi bacteremia in a 51-year-old man with diabetes and liver cirrhosis, on long-term corticosteroid therapy after skin-grafting surgery. The patient recovered soon after he was treated with vancomycin. This review focuses on the microbiological characteristics of this organism, and the diagnosis and treatment of this infection.展开更多
