Screening of Commercially Available Chlorine Based Sanitizers and their Efficacy in Reducing Microbial Load Levels of E. coli O157:H7 at High and Low Organic Load Environments

The presence of postharvest sanitizers has shown to be an effective approach to reducing microbial cross contamination in agricultural washing operations. However, choosing an appropriate sanitizer can be challenging due to produce commodity, processing conditions and interference with organic load. Current research shows a wide variety of methods to mimic the organic load of vegetable processing conditions, with paddle mixing and blender as the most commonly used. Controlling and understanding the physiochemical properties of wash water is key in maintaining sanitizer efficacy. The effects of simulated wash water preparation method on the physiochemical properties were tested at 0 and 50 COD(mg/L) and no significant difference was observed. However, at high levels of organic load results showed a significant difference between turbidity values at 1,500 COD. Free residual chlorine titration methods were compared, using DPD-titrimetric and Iodometric method. Results showed a significant difference between titration methods in organic load heavy environments. Commercially available chlorine based sanitizers, Pure Bright™ Germicidal Bleach and Clorox® Germicidal Bleach, were compared to a concentrated solution of sodium hypochlorite. Pure Bright™ Germicidal Bleach showed to perform the best by reducing 7 log CFU/ml of E. coli O157:H7 after 30 seconds in no organic load environments, whereas Clorox Germicidal bleach was able to reduce 7 log CFU/ml of E. coli O157:H7 after 30 minutes. These studies aim to provide best management practices for small in medium growers in the implementation of antimicrobial solutions for the maintenance of water quality in postharvest washing solutions

CONOCIMIENTO DE LOS EXPENDEDORES DE CARNE SOBRE EL FAENAMIENTO Y COMERCIALIZACIÓN, A TRAVÉS DE ANÁLISIS IMPLICATIVO Y DESCRIPTIVO. ESTUDIO DE CASO CAMAL RIOBAMBACHIMBORAZO- ECUADOR

In Ecuador meat is a basic part of the typical family diet. The investigation carried out uses descriptive and implicative statistical analysis to measure the perception and knowledge of meat retailers in the retail sector in the city of Riobamba, Ecuador. The study was conducted in 2015, with a sample of 471 participants, with 97% confidence level and an error of 5%. The information was gathered through a 30-question survey regarding product quality, and knowledge and perceptions of the retailers on meat sales. Chic y Excell were used for the tabulation of results. It was observed that the meat retailers do not handle their own business matters such as legislation or relevant aspects that affect the quality of the product offered to the public. It is determined that the sale of meat in the retail sector of the city considers three main actors: 58.4% of distributors who buy the butchered meat, 30.4% of middlemen who buy animals and skin them, and 7.9 % of producers who breed the animals that they skin. In the city sales are comprised of 22.5% white meat, 45.2% red meat and 31.6% both. In addition, 39.9% of meat sales happen in neighborhood stores, 21.4% in meat markets, 18.5% in fixed market stalls, 11.9% in farmer’s markets, and 7% in supermarkets. Distrust of the slaughterhouse is caused by poor perception people have of meat sold in Riobamba

The professional skills profile of a public affairs practitioner in Spain

Purpose: The present study identifies the professional skills profile that a Public Affairs (PA) practitioner of a major company or an organization representing the interests of various economic sectors should have in Spain. Design/methodology: The study uses a mixed qualitative and quantitative methodology. The initial identification of the competences, as well as the general functions of the profile to be evaluated, has been carried out using the in-depth interview technique with the directors of APRI (Association of Professionals of Institutional Relations of Spain), who defined these competencies from their expert perspective. Subsequently, through a survey of seventy-two managers, sufficient data were obtained to statistically process the information and obtain significant results in the identification of such competences. This information has been processed, firstly, through factorial analysis, which has made it possible to synthesize these competences. Once the analysis of factors was carried out, a cluster analysis is added for the classification of the respondents or managers. Findings: The perception of the interviewed executives has been determined regarding the functions that an institutional relations practitioner must fulfill. It should be noted that this is a profession for which there is no clarity about the role and the legitimacy of its members, particularly in Spain. In fact, it is associated with a function that is seen as exerting undue pressure on political power. A field study was conducted to determine the opinion of these managers on the competences that a professional in institutional relations should have. Originality/value: This study provides a description of the job position of a person responsible for institutional relations in Spain. Moreover, it adds a typology of managers, according to the competences defined for the person responsible for institutional relations.Peer Reviewe

The reading of hypertexts, their use and their incidence in communicative and Llnguistic practice in university students

La investigación se relaciona con la denominada sociedad de la información y la delimita al campo de la lectura de hipertextos y al uso, la apropiación y la reconfiguración de los nuevos lenguajes que encierran. En ese sentido, el estudio adelantado ofrece una explicación del lenguaje que se ha creado en Internet y de las nuevas prácticas comunicativas y lingüísticas (NPCL) que este ha generado entre los jóvenes universitarios. El estudio del hipertexto implica la necesidad de revisar el currículo y las prácticas de enseñanza en los cursos universitarios de producción y comprensión de textos, centrados hoy en la lengua castellana. También se considera importante establecer una regulación o unas normas mínimas a través de textos instructivos que les den un marco a los modos de lectura de hipertextos que se han abierto paso en la sociedad de la información. Este sería un reto para asumir, en especial por parte de las universidades y el Estado, pues es evidente la incidencia de la lectura de hipertextos en las nuevas prácticas lingüísticas y comunicativas de los jóvenes universitariosThe research is related to the so-called information society and delimits it to the field of reading hypertexts and to the use, appropriation and reconfiguration of the new languages that they contain. In this sense, the advance study offers an explanation of the language that has been created on the Internet and of the new communicative and linguistic practices (NPCL) that this has generated among university students. The study of hypertext implies the need to review the curriculum and teaching practices in the university courses of production and comprehension of texts, centered today in the Spanish language. It is also considered important to establish a regulation or minimum standards through instructive texts that give a framework to the reading modes of hypertexts that have made their way into the information society. This would be a challenge to take on, especially on the part of the universities and the State, since the incidence of reading hypertexts in the new linguistic and communicative practices of university students is eviden

Macroproyecto: estrategias y acciones para el cierre de brechas en capital humano en el sector metalmecánico de Caldas

Esta investigación ha contribuido a generar estrategias y acciones para el cierre de las brechas encontradas en la gestión del talento humano de las empresas del subsector metalmecánico estudiado. Da claridad de lo que sucede al interior de las empresas analizadas en torno a su capital humano y brinda evidencias acerca de aspectos organizacionales con debilidades que es necesario ajustar bajo la perspectiva del cierre de brechas. El proyecto se desarrolló a partir del análisis de información primaria recolectada mediante encuestas a 33 empresas de la cadena productiva de la Industria manufacturera del sector metalmecánico de Manizales. Al caracterizar el capital humano de las empresas se encontró que no cuentan con perfiles de cargos ni han considerado aspectos demográficos al momento de vincular personal; predomina el personal de género masculino, y en cuanto a contratación prima la vinculación a término fijo. Otro hallazgo es que la mayoría de las empresas no están realizando la gestión de talento/capital humano y se carece de conocimiento y capacidad alrededor del tema de competencias laborales. En referencia a las brechas se hallaron en calidad, cantidad y pertinencia, para cuyo cierre se plantean dos estrategias. Una de alianza entre gobierno, empresas e instituciones educativas para actuar en conjunto sobre las debilidades encontradas, y otra de sensibilización y formación de líderes y directivos del sector en talento/capital humano.This research has contributed to generate strategies and actions to close the gaps found in the management of human talent of the companies of the metalworking subsector studied. It gives clarity of what happens within the companies analyzed around their human capital and provides evidence about organizational aspects with weaknesses that need to be adjusted from the perspective of closing gaps. The project was developed from the analysis of primary information collected through surveys of 33 companies in the manufacturing chain of the manufacturing industry of the metalworking sector of Manizales. When characterizing the human capital of the companies, it was found that they do not have job profiles or have considered demographic aspects when linking personnel; Male staff predominates, and in terms of hiring, fixed-term employment is a priority. Another finding is that most companies are not performing talent / human capital management and there is a lack of knowledge and capacity around the subject of job skills. In reference to the gaps they were in quality, quantity and relevance, for whose closure two strategies are proposed. One of alliance between government, companies and educational institutions to act together on the weaknesses found, and another for raising awareness and training of leaders and managers of the sector in talent / human capital
