Cafés Especiales. El caso del Cauca en Colombia

El éxito en los mercados internacionales de la industria de los denominados cafés especiales, incluyendo el rápido aumento del número de pequeños-medianos tostadores de café de alta calidad y la aparición de "boutiques" de café, pone de manifiesto que existen consumidores capaces de apreciar y distinguir el café de calidad y además están dispuestos a pagar por él (Oberthuer et al., 2011). Colombia se caracteriza fundamentalmente por sus variedades de café procedentes de la especie Coffea arabica, obtenidos mediante el denominado procesado "húmedo" del café, que consiste en el despulpado, la licuefacción del mucílago por fermentación microbiana y su posterior retirada mediante el lavado con agua. Este método permite la obtención de los cafés verdes con mejor calidad aromática (Gonzalez-Rios et al., 2007) que en el mercado alcanzarán mayor precio, siendo estos la base para la obtención de los denominados cafés especiales.

Análisis del posicionamiento estratégico del café del Huila y el desarrollo de los cafés especiales

El proyecto de grado titulado “Análisis del posicionamiento estratégico del café del Huila y el desarrollo de los cafés especiales” tiene el objetivo general de estudiar y hacer públicas las ventajas de producir café de alta calidad en el departamento del Huila, puesto que existen algunas zonas del departamento que no tienen una producción de calidad certificada, lo cual ha generado cuellos de botella en relación a la demanda potencial y real con la Unión Europea. En la investigación se busca la manera de incrementar la zona productora de cafés especiales para satisfacer el mercado Europeo que es gustador del tipo de café que se cultiva en la región Huilense por la suavidad, aroma, entre otras variables influyentes. El desarrollo de este proyecto en esta región del país, se sustenta por la mayor producción de café a nivel nacional. Asimismo, también porque es el abanderado en cafés especiales y cuenta con la mayoría de fincas certificadas con algún sello de conducta en Colombia. Lo anterior, se ha alcanzado con la aplicación de buenas prácticas para la sostenibilidad del cultivo, la gran labor de renovación de cafetales y al don cafetero que tiene la gente del Huila debido a que es el negocio agrícola más importante.

Total Quality Management and Corporate Social Responsibility. Literature review. The case of Nabeiro Delta Cafés Group

The relationship between the themes of Total Quality Management (TQM) and Social Responsibility (CSR) through the concepts, approaches and models of excellence is a reality of sustainable and stable companies. Being organizations, people, act correctly and rightly do in society go through a quality management and social responsibility thereof. It is based on these two philosophies (Total Quality Management and Corporate Social Responsibility), which developed this literature review work, essentially based on a relational analysis in two papers, namely: "TQM and CSR Nexus" by Ghobadian et al. (2007) and "The Corporate Social Responsibility Audit Within the Quality Management Framework," de Kok et al. (2001) and applied to an organizational situation in concrete: the Nabeiro Delta Cafés Group - SGPS, SA.

Phase II Trial of Infusional Fluorouracil, Irinotecan, and Bevacizumab for Metastatic Colorectal Cancer: Efficacy and Circulating Angiogenic Biomarkers Associated With Therapeutic Resistance

Purpose We investigated the efficacy of fluorouracil (FU), leucovorin, irinotecan, and bevacizumab (FOLFIRI + B) in a phase II trial in patients previously untreated for metastatic colorectal cancer (mCRC), and changes during treatment in plasma cytokines and angiogenic factors (CAFs) as potential markers of treatment response and therapeutic resistance. Patients and Methods We conducted a phase II, two-institution trial of FOLFIRI + B. Each 14-day cycle consisted of bevacizumab (5 mg/kg), irinotecan (180 mg/m(2)), bolus FU (400 mg/m(2)), and leucovorin (400 mg/m(2)) followed by a 46-hour infusion of FU (2,400 mg/m(2)). Levels of 37 CAFs were assessed using multiplex-bead assays and enzyme-linked immunosorbent assay at baseline, during treatment, and at the time of progressive disease (PD). Results Forty-three patients were enrolled. Median progression-free survival (PFS), the primary end point of the study, was 12.8 months. Median overall survival was 31.3 months, with a response rate of 65%. Elevated interleukin-8 at baseline was associated with a shorter PFS (11 v 15.1 months, P = .03). Before the radiographic development of PD, several CAFs associated with angiogenesis and myeloid recruitment increased compared to baseline, including basic fibroblast growth factor (P = .046), hepatocyte growth factor (P = .046), placental growth factor (P < .001), stromal-derived factor-1 (P = .04), and macrophage chemoattractant protein-3 (P < .001). Conclusion Efficacy and tolerability of FOLFIRI + B appeared favorable to historical controls in this single arm study. Before radiographic progression, there was a shift in balance of CAFs, with a rise in alternate pro-angiogenic cytokines and myeloid recruitment factors in subsets of patients that may represent mechanisms of resistance.

Reciprocal changes in gene expression profiles of cocultured breast epithelial cells and primary fibroblasts

The importance of epithelial-stroma interaction in normal breast development and tumor progression has been recognized. To identify genes that were regulated by these reciprocal interactions, we cocultured a nonmalignant (MCF10A) and a breast cancer derived (MDA-MB231) basal cell lines, with fibroblasts isolated from breast benign-disease adjacent tissues (NAF) or with carcinoma-associated fibroblasts (CAF), in a transwell system. Gene expression profiles of each coculture pair were compared with the correspondent monocultures, using a customized microarray. Contrariwise to large alterations in epithelial cells genomic profiles, fibroblasts were less affected. In MDA-MB231 highly represented genes downregulated by CAF derived factors coded for proteins important for the specificity of vectorial transport between ER and golgi, possibly affecting cell polarity whereas the response of MCF10A comprised an induction of genes coding for stress responsive proteins, representing a prosurvival effect. While NAF downregulated genes encoding proteins associated to glycolipid and fatty acid biosynthesis in MDA-MB231, potentially affecting membrane biogenesis, in MCF10A, genes critical for growth control and adhesion were altered. NAFs responded to coculture with MDA-MB231 by a decrease in the expression of genes induced by TGF beta 1 and associated to motility. However, there was little change in NAFs gene expression profile influenced by MCF10A. CAFs responded to the presence of both epithelial cells inducing genes implicated in cell proliferation. Our data indicate that interactions between breast fibroblasts and basal epithelial cells resulted in alterations in the genomic profiles of both cell types which may help to clarify some aspects of this heterotypic signaling.

Pop-rock musicians: Assessment of their satisfaction provided by hearing protectors

Pop-rock musicians are at risk of developing hearing loss and other symptoms related to amplified music. Aim: The aim of the present study was to assess the satisfaction provided by the use of hearing protection in pop-rock musicians. Study design: Contemporary cohort study. Materials and Methods: A study of 23 male pop-rock musicians, aged between 25 to 45 years. After audiological evaluation (pure tone audiometry, middle ear analysis, TEOAE and DPOAE) hearing protective devices were provided to be used for three months. After that musicians answered a satisfaction assessment questionnaire. Results: The prevalence of hearing loss was of 21.7%. The most common complaints about the hearing protectors were: autophonia, pressure in the ears, interference in high frequencies perception and full time use of the hearing protector during concerts. There was a positive correlation between a reduction in tinnitus after the use of the HPD with the following complaints: tinnitus after beginning the career (p=0.044), discomfort with the sound intensity in the work place (p=0.009) and intolerance to loud sound (p=0.029). Conclusions: There was a high prevalence of hearing loss and a positive tendency towards the use of the ear protector device among the sample population.

XII Iberian-Italian Congress of Financial and Actuarial Mathematics

"The purpose of the XII Iberian-Italian Congress of Financial and Actuarial Mathematics is to provide a meeting point for researchers in Financial Economics from different countries and research backgrounds in universities, government or financial institutions. In fact, the Congress which is currently taking place in Lisbon has been organized to encourage communication and debate among the participants as well as to reinforce the bonds between us.The current edition of the Congress is characterized by the quality and diversity of the papers that have been submitted with special attention to the International Financial Crisis and measures of risk in different financial markets. However, as the Congress Program indicates, there are also parallel sessions about traditional topics in finance such as asset pricing, insurance, corporate finance, etc.Although this Congress has always been organized alternately between Spain and Italy, this year we have the great pleasure of celebrating it in Portugal which will be included as a permanent partner."

Qualidade do serviço e satisfação do cliente

A Payshop S.A. é a empresa do grupo CTT - Correios de Portugal, Sociedade Aberta, responsável pela implantação em Portugal de um serviço que permite aos consumidores efetuar o pagamento de variados produtos utilizando para isso uma rede de estabelecimentos comerciais de proximidade como papelarias, cafés e quiosques. A sua criação remonta a 2001, mas só em 2004 é que os CTT – Correios de Portugal adquirem a totalidade da empresa, anteriormente detida, em parceria, com acionistas anónimos. Devido à missão dos CTT, a aquisição, na totalidade, da Payshop faz todo o sentido, pois, desta forma, asseguram soluções de comunicação e logística, de proximidade e excelência, estabelecendo, assim, relações de confiança, estando sempre a inovar. A Payshop foi vista como forma de promover soluções para dar resposta integrada às necessidades de cada cliente. O objetivo fundamental da presente dissertação é investigar a perceção da qualidade de serviço e satisfação do cliente da Payshop, de forma a identificar quais os serviços mais utilizados e qual a periodicidade de utilização, fazendo também considerações relativas a uma alternativa ou serviço complementar, como a criação de uma plataforma virtual, de forma a alargar a clientes mais jovens a proximidade e facilidade de uso, pois o uso e-commerce é cada vez mais utilizado por este tipo de cliente. No entanto, a questão da segurança de utilização deste tipo de serviço tem, ainda, que ser mais trabalhada. Participaram no presente estudo 157 indivíduos, com idades entre os 16 e acima dos 45 anos, todas elas com acesso à internet. A ferramenta utilizada foi um inquérito, desenvolvido e validado ao longo deste trabalho, divulgado nas redes sociais. Os principais resultados encontrados neste estudo permitem consolidar a perceção das exigências dos consumidores e satisfação dos mesmos nos serviços prestados em relação à sua comodidade.
