Borrelia burgdorferisensu lato infection has been confirmed in clinical cases in the northeast of Mexico; however, the bacterium has not been identified as infecting the tick vector Ixodes, Amblyomma and Dermacentor ticks were collected from mammals and plants in northeastern Mexico and examined for Borrelia. Eighteen of 214 ticks were PCR-positive for the fla and 16S rRNA genes and 15 for the ospA gene. Southern blotting with a fla probe and sequencing of ospA genes confirmed infection with B. burgdorferi sensu stricto. These findings, together with reports of indigenous cases, fulfil the criteria that allow northeastern Mexico to be considered as a zone endemic for Lyme disease.

Purpose This study aims to generate additional insights into the relationship between knowledge sharing (KS) and psychological safety (PS) in an inter-organisational arrangement through the lens of the knowledge-based view and PS theory. Design/methodology/approach A relational data survey was designed to collect systematic information from key actors in two manufacturing organisations. The questionnaire assessed KS as the dependent variable and four independent variables – three behavioural (respect, tolerance, trust) and one contextual (suitable working environment) – as proxies of PS. The multiple regression quadratic assignment procedure was used to analyse the effect of PS on KS. Findings This paper strengthens the findings of previous studies that identify PS as a relevant antecedent of KS in organisations. Additionally, the paper also suggests that a relational approach is more relevant to understand PS as a group concept measured through networks of respect, tolerance, trust and suitable working environments. Practical implications This study may help managers identify ways in which they can strengthen the work-related relationships when such behavioural and contextual variables occur in inter-organisational arrangements, and thus obtaining additional relational rents based on an increase in KS. Originality/value This study contributes to the literature on how KS in organisations is driven by behavioural and contextual variables that can be operationalised as PS. Moreover, this study expands the understanding of previous research on PS by taking a relational approach to its conceptualisation and measurement within a Latin American context.

ResumenEl objetivo del artículo es estudiar la percepción que estudiantes de posgrado tienen sobre la tutoría recibida en sus estudios de posgrado. Se consideran tres programas de maestría para identificar los factores que influyen en la motivación y satisfacción hacia el trabajo realizado por el director de tesis (tutor) y poder así identificar posibles áreas de mejora en beneficio de los posgrados. Es un estudio descriptivo y transversal con información recolectada de 60 egresados. Los resultados reflejan que los egresados están satisfechos con la tutoría que recibieron de parte de sus profesores directores de tesis, sintiendo una adecuada conexión emocional, retroalimentación, motivación y palabras de aliento de parte de los tutores. Sin embargo, se encontró que la falta de voluntad para continuar con el trabajo de tesis es un elemento que ha provocado que un porcentaje de ellos no hayan obtenido el grado. Se proponen estrategias de intervención como el seguimiento de las trayectorias académicas y la implementación de talleres de tesis. Palabras clave: tutoría, dirección de tesis, estudios de posgrado, talleres de tesis Perception of the Motivation and Satisfaction Received from the Tutoring in Graduate StudiesThe objective of this article is to study the perception that graduate students have of the thesis supervisor (tutor) during his/her graduate studies. Three Master programs were considered in the study to identify factors that influence motivation and satisfaction towards the work made by the thesis advisor and being able to identify possible improvement areas in benefit of graduate studies. This is a descriptive and transversal study with information collected from 60 graduate students. The results show that graduate students are satisfied with the guide provided by their thesis advisors, feeling an adequate emotional connection, feedback, motivation and words of encouragement from the advisors. However, it was found that the lack of willingness by the students to continue with the thesis is an element causing that a significant percentage have not obtained the master degree. Intervention strategies such as tracing academic careers and the implementation of thesis workshop are proposed. Keywords: tutoring, thesis direction, graduate studies, thesis workshopFormación Universitaria Vol. 9(2), 49-58 (2016) Los posgrados que se analizaron en la presente investigación son tres: 1) maestría en administración, 2) maestría en ingeniería industrial y 3) maestría en informática. Los tres programas cuentan con 29 profesores que tienen una edad promedio aproximada de 53 años y una antigüedad media de 26 años de servicio, la mayor parte de los académicos llevan más de veinte años asesorando tesis. Los alumnos que transitan por los programas, en su mayoría son profesionistas que se encuentran laborando en la industria y que buscan en la maestría oportunidades de adquisición de conocimiento que los lleven a obtener herramientas que les permiten tener un mejor desempeño en el ámbito laboral y por ende un crecimient...
