Para evaluar el impacto de un Tratado de libre comercio (TLC) entre Colombia y Estados Unidos, describimos las características de la economía colombiana, enfatizando en sus patrones y perspectivas de comercio, e identificando los sectores y regiones más sensibles a la firma de un TLC. Afirmamos que los efectos de un acuerdo bilateral entre Colombia y Estados Unidos, serán similares a los que han tenido anteriores reformas de liberalización comercial. Sin embargo, mientras Colombia espera la firma del TLC con Estados Unidos, ese país está cerca de firmar tratados bilaterales con algunos países de Latinoamérica. Por lo tanto, también puede haber efectos sobre la economía colombiana producto del cambio en las reglas comerciales entre sus socios. Primero analizamos el efecto de anteriores reformas comerciales en Colombia, México y Chile. Luego, a través de un modelo de equilibrio general multiregional aplicado, simulamos los efectos sobre la economía colombiana de un acuerdo bilateral con Estados Unidos. Concluimos que, aunque moderados, habrá aumentos en el bienestar y en la producción de los consumidores y firmas colombianos.

Community research fatigue has been understudied within the context of community-university relationships and knowledge production. Community-based research (CBR), often occurring within a limited geography and population, increases the possibility that community members feel exhausted or over-whelmed by university research —particularly when they do not see tangible results from research activities. Prompted by informal stories of research fatigue from community members, a small graduate student team sought to understand the extent to which community members experienced research fatigue, and what factors contributed to or relieved feelings of research fatigue. In order to explore these dimensions of research fatigue, semi-structured, face-to-face interviews were conducted with 21 participants, including community members (n = 9), staff and faculty (n = 10), and students (n = 2). The objective of the research was to identify university practices that contribute to research fatigue and how to address the issue at the university level. Qualitative data analysis revealed several important actionable findings: the structure and conduct of community-based research, structured reciprocity and impact, and the role of trust in research. This study’s findings are used to assess the quality of Clark University’s research relationship with its adjacent community. Recommendations are offered; such as to improve partnerships, the impact of CBR, and to develop clear principles of practice.

The development of TDR for measurement of soil water content and electrical conductivity has resulted in a large shift in measurement methods for a breadth of soil and hydrological characterization efforts. TDR has also opened new possibilities for soil and plant research. Five examples show how TDR has enhanced our ability to conduct our soil- and plant-water research. (i) Oxygen is necessary for healthy root growth and plant development but quantitative evaluation of the factors controlling oxygen supply in soil depends on knowledge of the soil water content by TDR. With water content information we have modeled successfully some impact of tillage methods on oxygen supply to roots and their growth response. (ii) For field assessment of soil mechanical properties influencing crop growth, water content capability was added to two portable soil strength measuring devices; (a) A TDT (Time Domain Transmittivity)-equipped soil cone penetrometer was used to evaluate seasonal soil strengthwater content relationships. In conventional tillage systems the relationships are dynamic and achieve the more stable no-tillage relationships only relatively late in each growing season; (b) A small TDR transmission line was added to a modified sheargraph that allowed shear strength and water content to be measured simultaneously on the same sample. In addition, the conventional graphing procedure for data acquisition was converted to datalogging using strain gauges. Data acquisition rate was improved by more than a factor of three with improved data quality. (iii) How do drought tolerant plants maintain leaf water content? Non-destructive measurement of TDR water content using a flat serpentine triple wire transmission line replaces more lengthy procedures of measuring relative water content. Two challenges remain: drought-stressed leaves alter salt content, changing electrical conductivity, and drought induced changes in leaf morphology affect TDR measurements. (iv) Remote radar signals are reflected from within the first 2 cm of soil. Appropriate calibration of radar imaging for soil water content can be achieved by a parallel pair of blades separated by 8 cm, reaching 1.7 cm into soil and forming a 20 cm TDR transmission line. The correlation between apparent relative permittivity from TDR and synthetic aperture radar (SAR) backscatter coefficient was 0.57 from an airborne flyover. These five examples highlight the diversity in the application of TDR in soil and plant research.

This study explores the origins and development of honors education at a Historically Black College and University (HBCU), Morgan State University, within the context of the Maryland higher education system. During the last decades, public and private institutions have invested in honors experiences for their high-ability students. These programs have become recruitment magnets while also raising institutional academic profiles, justifying additional campus resources. The history of higher education reveals simultaneous narratives such as the tension of post-desegregated Black colleges facing uncertain futures; and the progress of the rise and popularity of collegiate honors programs. Both accounts contribute to tracing seemingly parallel histories in higher education that speaks to the development of honors education at HBCUs. While the extant literature on honors development at Historically White Institutions (HWIs) of higher education has gradually emerged, our understanding of activity at HBCUs is spotty at best. One connection of these two phenomena is the development of honors programs at HBCUs. Using Morgan State University, I examine the role and purpose of honors education at a public HBCU through archival materials and oral histories. Major unexpected findings that constructed this historical narrative beyond its original scope were the impact of the 1935/6 Murray v Pearson, the first higher education desegregation case. Other emerging themes were Morgan’s decades-long efforts to resist state control of its governance, Maryland’s misuse of Morrill Act funds, and the border state’s resistance to desegregation. Also, the broader histories of Black education, racism, and Black citizenship from Dred Scott and Plessy, the 1863 Emancipation Proclamation to Brown, inform this study. As themes are threaded together, Critical Race Theory provides the framework for understanding the emerging themes. In the immediate wake of the post-desegregation era, HBCUs had to address future challenges such as purpose and mission. Competing with HWIs for high-achieving Black students was one of the unanticipated consequences of the Brown decision. Often marginalized from higher education research literature, this study will broaden the research repository of honors education by documenting HBCU contributions despite a challenging landscape.

In this work, pyrolysis-molecular beam mass spectrometry analysis coupled with principal components analysis and (13)C-labeled tetramethylammonium hydroxide thermochemolysis were used to study lignin oxidation, depolymerization, and demethylation of spruce wood treated by biomimetic oxidative systems. Neat Fenton and chelator-mediated Fenton reaction (CMFR) systems as well as cellulosic enzyme treatments were used to mimic the nonenzymatic process involved in wood brown-rot biodegradation. The results suggest that compared with enzymatic processes, Fenton-based treatment more readily opens the structure of the lignocellulosic matrix, freeing cellulose fibrils from the matrix. The results demonstrate that, under the current treatment conditions, Fenton and CMFR treatment cause limited demethoxylation of lignin in the insoluble wood residue. However, analysis of a water-extractable fraction revealed considerable soluble lignin residue structures that had undergone side chain oxidation as well as demethoxylation upon CMFR treatment. This research has implications for our understanding of nonenzymatic degradation of wood and the diffusion of CMFR agents in the wood cell wall during fungal degradation processes.

This paper evaluates the role Strategic Research Partnerships (SRPs) play in Asia. Specific Asian institutional settings influence the roles of SRPs. Japan is regarded as a forerunner in the practice of SRPs. In Japan, lack of spillover channels, limited opportunities for mergers and acquisitions, weak university research and pressure for internal diversification motivate firms to form SRPs. In Korea, SRPs are regarded as a means to promote large-scale research projects. In Taiwan, SRPs are formed to facilitate technological diffusion. Empirical findings on SRPs, focusing on government-sponsored R&D consortia in Japan, are summarized. Issues regarding SRP formation, their effect on R&D spending of participating firms, and productivity, are examined. Reference is made to alternative forms of measurement of SRPs and their potential application to Asian countries is assessed. Enhancing the capacity of policy-makers to assess the extent and contribution of SRPs is considered to be a priority.

Recent trends in technology transfer show an intensification of spin-off creation as a modality of university research commercialisation, complementary to the conventional ones, contract research and licensing. In this paper we analyse the evolution, objectives, resources and activities of a specialised unit –Technological Trampoline (TT) - in charge of new venture creation at the University of Girona (Catalonia-Spain). Based on two theoretical frameworks, Resource-based-view and Institutional Theory, we adopt a multi-dimensional approach to study the strategy of spinning-off new ventures at the University of Girona in terms of resources and activities, how this process is organised and if the outputs fit with this UdG’s objectives and the local environment. Our main contribution is an in-depth analysis of the spin-off creation unit with special emphasis on its variety of resources and activities. The results have a series of implications and recommendations at both university and TT level.

In the Finnish university society the commercialization research projects has not been a focus of interest until now. The reasons for the growing interest towards commercialization research projects are their possibility to develop our economy simultaneously by providing new technologies and products. This study focuses on the examination of what kind of high-technology oriented research can be commercialized and how. The aim is to generate understanding of how commercialization research projects should proceed and to find concrete ways of improving the of commercialization research projects. As its research method, the study analyzes four different university high-technology research projects which have been commercially oriented and have to some degree been able to commercialize the product or technology developed during the research phase. The data has been gathered mainly by semi-structured interviews of people involved in these particular projects or cases. The findings from the interviews have been reflected to the final reports of the projects, provided by TEKES, and later on the data gained has been compared to each other. Also a literature review has been produced about the subject of commercializing university research with the purpose of providing known theories and framework connected with the subject. The study reveals five main factors related to commercializing high-tech research. These factors are: The Team, Market potential and competitiveness, Product and technology, Funding and Steering Group. Also the uncertainties related to these factors have been addressed. As a conclusion the study provides the main aspects that should be considered when starting a commercialization research project. Also a combining hierarchical framework has been provided related to the five factors presented. In Chapter 5 the study addresses the main tasks or steps to be taken in order to get public funding for a commercially oriented research project and later on the actual steps to be executed in order to successfully commercialize these high-tech research projects.
