An integrated approach to delimiting species borders in the genus Chrysotoxum Meigen, 1803 (Diptera: Syrphidae), with description of two new species

Integrative taxonomy tests the validity of taxa using methods additional to traditional morphology. The existence of two different morphotypes in specimens identified as Chrysotoxum vernale Loew (Diptera: Syrphidae) prompted their taxonomic study using an integrative approach that included morphology, wing and male-surstylus geometric morphometrics, genetic and ecological analyses. As a result, a new species is recognised, Chrysotoxum montanum Nedeljković & Vujić sp. nov., and C. vernale is re-defined. A lectotype and paralectotypes are designated for C. vernale to stabilize this concept. An additional species, Chrysotoxum orthostylum Vujić sp. nov., with distinctive male genitalia is also described. The three species share an antenna with the basoflagellomere shorter than the scape plus pedicel and terga with yellow fasciae not reaching the lateral margins. This study confirms the value of integrative approach for resolving species boundaries.

Competence profile differences among graduates from different academic subject fields: implications for improving students’ education

The aim of a university education is the intellectual development of citizens, and the training of professionals for their subsequent entry into the workforce. However, this entry into the workforce, following the theoretical education usually provided by the university, implies that students have to manage this difficult transition by themselves. Society, in a continual process of transformation, requires of universities that they adjust, adapting the education they offer to comply with the demands of society and the workplace. Socio-emotional skills would seem to have influence predicting professional performance. These skills also influence job-finding and employability. Consequently, providing teachers with an education in socioemotional competences is becoming a necessary task within universities, and the majority of teaching staff consider these skills to be fundamental to the personal and socio-emotional development of students. The objective of our proposed work is to establish the characteristic profile of competences of a sample of teachers in training, and compare it with the competences profile of graduate students belonging to the fields of law sciences, social sciences, humanities, science and technology, and health. Starting from results, implications will be derived for the development of generic competences of socio-emotional type in the framework of the European Frame of Higher Education.

Psychometric properties of the Spanish adaptation of the School Attitude Assessment Survey-Revised

Background: The assessment of attitudes toward school with the objective of identifying adolescents who may be at risk of underachievement has become an important area of research in educational psychology, although few specific tools for their evaluation have been designed to date. One of the instruments available is the School Attitude Assessment Survey-Revised (SAAS-R). Method: The objective of the current research is to test the construct validity and to analyze the psychometric properties of the Spanish version of the SAAS-R. Data were collected from 1,398 students attending different high schools. Students completed the SAAS-R along with measures of the g factor, and academic achievement was obtained from school records. Results: Confirmatory factor analysis, multivariate analysis of variance and analysis of variance tests supported the validity evidence. Conclusions: The results indicate that the Spanish version of the SAAS-R is a useful measure that contributes to identification of underachieving students. Lastly, the results obtained and their implications for education are discussed.

Estrategias determinantes para la competitividad de un destino de sol y playa. El caso de Mazatlán, Sinaloa, México

El presente estudio se realizó con el propósito de dar un entendimiento global de la situación actual en lo referente a la competitividad de Mazatlán como destino turístico; conocer las particularidades del destino permite aplicar procedimientos innovadores y participativos en la búsqueda de competitividad, lo que favorece un mejor desarrollo turístico. El principal valor de esta investigación radica en la necesidad de identificar las estrategias para lograr competitividad y convertir el turismo de sol y playa en una palanca de desarrollo económico y generadora de empleos. El estudio se realizó bajo la perspectiva metodológica cualitativa ejecutada a través de diferentes métodos; por un lado, el enfoque de triangulación implicó análisis documental para contextualizar la competitividad turística del destino y por otro lado, análisis de datos generados de las discusiones en grupos focales con los actores de la actividad turística del destino. Se revisaron los fundamentos teóricos de la competitividad sistémica, con referencia especial al Índice de Competitividad Sistémica de las Ciudades Mexicanas (ICSar-ciudades) únicamente para definir indicadores o categorías analíticas que fueron incluidos en la discusión (marco regulatorio, ambiente de negocios e infraestructura y recursos humanos, culturales y naturales). Entre los principales resultados, se destaca la necesidad empaquetar los atractivos turísticos del destino, lo cual permita constituir un producto turístico, tarifado y publicado como un elemento completo; la necesidad de contar con adecuados canales de distribución y comercialización; un adecuado sistema de movilidad en el destino que cubra las necesidades de los turistas; el fortalecimiento de la infraestructura turística para maximizar los flujos turísticos; colaboración de todos los niveles de gobierno e Instituciones, sectores públicos o privados en el diseño e implementación de planes de marketing.

Developing pre-service teachers’ noticing of students’ understanding of the derivative concept

This research study examines the development of the ability of pre-service teachers to notice signs of students’ understanding of the derivative concept. It analyses preservice teachers’ interpretations of written solutions to problems involving the derivative concept before and after participating in a teacher training module. The results indicate that the development of this skill is linked to pre-service teachers’ progressive understanding of the mathematical elements that students use to solve problems. We have used these results to make some suggestions for teacher training programmes.
