¡Nuestro jefe es un buen jefe! Los efectos transnivel del liderazgo transformacional sobre el engagement en el trabajo en puesto de servicio

In service work, emotional demands are important due to their effects on social interactions with customers, patients, pupils, etc. The purpose of this study is to examine how emotional demands and leadership are related to engagement of the team members. The sample consists of 1,079 employees nested in 124 work teams from four Spanish public organizations. Multilevel analyses showed: 1) a positive effect of emotional demands on work engagement, 2) a crosslevel effect of leadership on work engagement, and 3) a cross-level moderation effect of leadership on the relationship between emotional demands and work engagement. Results suggest that shared perceptions of leadership by teams affect their work engagement levels directly and through an interaction effect on the emotional demands-engagement relationship. When employees feel emotionally overloaded, their leaders can relieve this negative impact on their levels of work engagement. Practical and theoretical implications are presented.En el trabajo de servicio, las demandas emocionales son importantes debido a sus efectos sobre las interacciones sociales con clientes, pacientes, alumnos, etc. El propósito de este estudio es examinar cómo se relacionan las demandas emocionales y el liderazgo con el engagement en el trabajo de los miembros del equipo. La muestra consiste en 1,079 empleados anidados en 124 equipos de trabajo de cuatro organizaciones públicas españolas. Los análisis multinivel mostraron: 1) un efecto positivo de las demandas emocionales sobre el engagement en el trabajo, 2) un efecto, a través de los niveles, del liderazgo sobre el engagement en el trabajo y 3) un efecto de moderación, a través de los niveles, del liderazgo sobre la relación entre las demandas emocionales y el engagement en el trabajo. Los resultados sugieren que las percepciones compartidas sobre el liderazgo que tiene el equipo afectan a sus niveles de engagement en el trabajo directamente y a través de un efecto de interacción sobre la relación demandas emocionales-engagement. Cuando los empleados se sienten emocionalmente sobrecargados, sus líderes pueden aliviar este impacto negativo en sus niveles de engagement en el trabajo. Se presentan implicaciones teóricas y prácticas

Structure and genetic diversity in wild and cultivated populations of Zapote mamey (Pouteria sapota, Sapotaceae) from southeastern Mexico: its putative domestication center

Tropical fruit trees are an important component of the human diet; however, little is known about their genetic diversity levels. Zapote mamey (Pouteria sapota) is a tree native to southeastern Mexico and Central America, and Mexico is the leading producer in the world. Studies of the genetic diversity of Zapote mamey have been based on cultivated materials using morphological and biochemical characterization or dominant molecular markers. To gain a deeper understanding about the conservation status of Zapote mamey in its center of origin and domestication, we collected 188 individuals from eight wild and five cultivated populations in southeastern Mexico and characterized them using eight microsatellite loci. STRUCTURE, 3D-PCoA, and neighbor-joining analyses showed three groups in the wild gene pool and one group in the cultivated gene pool. FST values were significant between wild and cultivated gene pools, among the four groups observed and among the 13 populations collected (0.13, 0.25, and 0.36, respectively). Overall, we found low levels of genetic diversity (A = 2.77, HO = 0.29, HE = 0.39), permutation tests did not show significant differences between wild and cultivated gene pools. The Garza–Williamson index showed low values in both gene pools (wild = 0.16, cultivated = 0.11) and the Bottleneck program indicated a decrease in genetic diversity in both gene pools (wild, P = 0.027; cultivated, P = 0.054); both analyses suggest a potential genetic bottleneck within this species. This study can help to generate adequate sampling techniques and to develop effective management strategies for Zapote mamey of southeastern Mexico

Filosofía: El valor de lo inútil

Hay dos tipos de cosas inútiles: aquellas que no aportan nada y las que nos permiten crecer en el amor, conocimiento y libertad. Esas son las cosas que realmente merecen la pena en la vida

Envejeciendo con Dignidad

Tablas, anexosEste estudio está basado en las diferentes problemáticas reales que se presentan al interior de las familias de las personas que asisten a la casa Palermo (Secretaria Distrital de Integración Social), en donde se utilizan Instrumentos de recolección de información como metaplán (para hacer un diagnostico rápido participativo), en el cual la población objeto, visibiliza y visualiza los posibles problemas que se presentan en el ámbito familiar. De la misma forma se hace una investigación que servirá para diseñar una propuesta de intervención para tratar el maltrato y las problemáticas que inciden en este, profundizando y estableciendo relaciones causales entre las diversas categorías que allí se presentan, que sirva como instrumento para implementar en la Casa de Integración Social Palermo con las personas que asisten y sus familias. Limitaciones que se han presentado son: la dificultad con el permiso para trabajar con el 20 % de los adultos mayores de la casa Palermo, debido al problema de tiempo y espacio en cuanto a las reuniones con la Directora y la población muestra de los adultos mayores. De otra parte los alcances están dirigidos a la obtención de la información relevante en el proceso de sensibilización ante el tema de la escasa comunicación asertiva, al reconocimiento de los factores influyentes en el maltrato familiar.No Abstrac

When differences do not matter: inclusion in a Mexican primary school

Studies show that disability is a cause of educational exclusion worldwide. Different countries adopt different views of the inclusion movement. Different variables seem to be associated with the success or failure of inclusion. This study takes place in a primary school located in Mexico. It aims to identify how inclusion is experienced by children with and without special needs, and the connections between inclusion and quality of life. Measures utilized were the questionnaire My Primary School from the Index for Inclusion and the Questionnaires on Assessment of Quality of Life for Children, self-report, and parents’ report. Participants are 69 regular students and 15 students with special education needs. Self-reports from regular children and proxy reports from the mothers of the special education needs students were analysed. Results indicated that there is an association between perceived inclusion and experiencing quality of life; having special needs does not impact on scores on QoL or inclusion; educational level does not impact on perceived QoL or inclusion for special education students. These results are discussed in light of a culture that appreciates diversity

Enchondroma versus Low-Grade Chondrosarcoma in Appendicular Skeleton: Clinical and Radiological Criteria

Objectives. To determine the validity of clinical and radiological features of enchondroma and low grade chondrosarcoma, and contrast the biopsy results with the clinical diagnosis based on the history and imaging. Material and Method. The study included 96 patients with cartilage type lesions suggestive of an enchondroma (E) or an low grade chondrosarcoma (LGC) according to the clinical and imaging data. The hypotheses were contrasted with the biopsy. Results. Of the 82 patients studied completely, 56 were considered E (68.29%), 8 as LGC (8.33%) and in 18 (18.75%) were doubtful cases and considered as suspected LGC. Of these, the biopsy showed 4 E (25%), 10 LGC (50%) and 4 were not definitive. On the other hand, of the 56 cases diagnosed as E, 15 were biopsied, 5 of these biopsies turned out to be LGC (33.3%). The 8 cases diagnosed as LGC, were also biopsied and only 4 biopsies (50%) confirmed the initial diagnosis. Features analyzed in the study showed no statistically significant difference. Correlation analysis between the diagnosis issued initially and the biopsy result gave a value of 0.69 (kappa coefficient), which was considered a good correlation. Conclusion. Features analyzed did not have any statistical significance. However, there was a good correlation between initial diagnosis and biopsy's result

“Education Network” a new way to teach Chemistry

The complexity of chemistry has implications for the teaching of chemistry. That chemistry is a very complex subject. The majority of the students at University think that chemistry is a difficult discipline and they have difficulty in understanding the concepts. Moreover, students' interest in chemistry decreases the first year at university. The reason for this decrease might be that the contents of chemistry laboratory classes are boring, out of date and lacking of dynamism that students experience through visual media tools. For these reasons, new programs and methodologies should be developed. Those are based on making chemistry relevant through problem solving and collaborative learning hold promise for reforming chemistry education. It is about an education according to circumstances, which is adapted to context and virtual behaviour of people. It's time to CRUSH boredom by transforming your classroom into an Escape Room adventure. School-based escape games are a great teaching tool. The students while playing, learn. The most important point is that they won’t realize they’re doing both at the same time. In this work, an educational gamification experience based on the escape room concept was developed. The first (Do It Yourself) DIY Escape Room was built the year before at Mechanical Engineer Degree started, that took more than three weeks of work. It was presented to other professors to the same subject at different degrees. That DIY Escape Room was modified and adapted to each group. Each professor changed the clues, problems and so on in order to orientate the topic as much as possible to their students.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech
