Lean Transition of Emerging Industrial Capability (LeanTEC) program was a cooperative agreement between the Boeing Company and AFRL conducted from January 1998 to January 2002. The results of this program are documented in the Manual for Effective Technology Transition Processes included as an attachment to this report. This manual provides processes, procedures, and tools for greatly improving technology transition in the aerospace industry. Methodology for the implementation of these improvements is given along with methods for customizing the various processes, procedures, and tools for a given company or business unit. The indicated methodology was tested by the LeanTEC team and results are documented in the report.

Using a panel of Colombian banks and quarterly data between 1996:1 and 2010:3, we study the relationship between short-run adjustemnts in bank capital buffers and the business cycle. We follow a partial adjustment framework and control for several variables that have been identified as important determinants of bank capital buffers in previous studies, and find that bank capital buffers vary over the business cycle. We are able to identify a negative co-movement of capital buffers and and the business cycle. However, we also find that capital buffers of small and large banks behave asymmetrically during the business cycle. While the former appear to be constant over time, once the appropriate set of control variables is used, the latter present a countercyclical behavior. Our results suggest the possible need of the implementation of regulatory policy measures in developing countries

This study examines ICT adoption among 3,759 Colombian manufacturing firms, and attempts to identify the factors that are conducive to the adoption and usage of ICT at the firm level. Our major findings are (i) that the adoption of a given information and communication technology is better facilitated when a firm is relatively large, has large human capital, engages in more innovative activities, and when a firm’s organizational structure is better aligned with the given technology; (ii) that positive associations between the key determinants and ICT adoptions are more pronounced for small and medium-sized firms than for large ones, and (iii) that information spillovers within industries is also a determinant of ICT adoptions by the firms.

L'activitat humana representa una de les majors causes d'entrada d'una gran varietat de substàncies en els ecosistemes fluvials. L'objectiu principal d'aquest treball es investigar els efectes que els tòxics orgànics poden exercir en els biofilms fluvials. El riu Llobregat ha estat sotmès a fortes pressions, fet que l'ha portat a uns nivells molt elevats de contaminació. En aquest estudi s'ha observat una influència dels plaguicides presents al riu en la distribució de la comunitat de diatomees, així com efectes en el biofilm a nivell funcional i estructural. Experiments amb canals experimentals han mostrat que l'herbicida diuron i el bactericida triclosan poden ocasionar una cadena d'efectes en els biofilms, incloent efectes directes i també efectes indirectes en les relacions entre els components del biofilm. Experiments amb cultius algals han mostrat que aquests tòxics, aplicats en barreja, poden tenir una major toxicitat de la prevista pels models, resultant en efectes sinèrgics.

The increasing burden of emerging infectious diseases worldwide confronts us with numerous challenges, including the imperative to design research and responses that are commensurate to understanding the complex social and ecological contexts in which infectious diseases occur. A diverse group of scientists met in Hawaii in March 2005 to discuss the linked social and ecological contexts in which infectious diseases emerge. A subset of the meeting was a group that focused on ‘‘transdisciplinary approaches’’ to integrating knowledge across and beyond academic disciplines in order to improve prevention and control of emerging infections. This article is based on the discussions of that group. Here, we outline the epidemiological legacy that has dominated infectious disease research and control up until now, and introduce the role of new, transdisciplinary and systems-based approaches to emerging infectious diseases.Wedescribe four cases of transboundary health issues and use them to discuss the potential benefits, as well as the inherent difficulties, in understanding the social–ecological contexts in which infectious diseases occur and of using transdisciplinary approaches to deal with them.
