Testing the entrepreneurial intention model on a two-country sample

This paper tests the Entrepreneurial Intention Model -which is adapted from the Theory of Planned Behavior- on a sample of 533 individuals from two quite different countries: one of them European (Spain) and the other South Asian (Taiwan). A newly developed Entrepreneurial Intention Questionnaire (EIQ) has being used which tries to overcome some of the limitations of previous instruments. Structural equations techniques were used in the empirical analysis. Results are generally satisfactory, indicating that the model is probably adequate for studying entrepreneurship. Support for the model was found not only in the combined sample, but also in each of the national ones. However, some differences arose that may indicate demographic variables contribute differently to the formation of perceptions in each culture.

Entrepreneurial intention, cognitive social capital and culture: empirical anaylisis for Spain and Taiwan

The main purpose of this paper is building a research model to integrate the socioeconomic concept of social capital within intentional models of new firm creation. Nevertheless, some researchers have found cultural differences between countries and regions to have an effect on economic development. Therefore, a second objective of this study is exploring whether those cultural differences affect entrepreneurial cognitions. Research design and methodology: Two samples of last year university students from Spain and Taiwan are studied through an Entrepreneurial Intention Questionnaire (EIQ). Structural equation models (Partial Least Squares) are used to test the hypotheses. The possible existence of differences between both sub-samples is also empirically explored through a multigroup analysis. Main outcomes and results: The proposed model explains 54.5% of the variance in entrepreneurial intention. Besides, there are some significant differences between both subsamples that could be attributed to cultural diversity. Conclusions: This paper has shown the relevance of cognitive social capital in shaping individuals’ entrepreneurial intentions across different countries. Furthermore, it suggests that national culture could be shaping entrepreneurial perceptions, but not cognitive social capital. Therefore, both cognitive social capital and culture (made up essentially of values and beliefs), may act together to reinforce the entrepreneurial intention.

Transección pancreática mediante un nuevo dispositivo asistido por radiofrecuencia en un modelo porcino de pancreatectomía distal laparoscópica: estudio de factibilidad

La morbilitat relacionada amb el desenvolupament de la fístula pancreàtica postoperatòria (FP) posteriorment a realitzar una pancreatectomia distal persisteix elevada. Hem realitzat un treball experimental per a avaluar la factibilitat de la realització de la transecció pancreàtica mitjançant un nou dispositiu assistit per radiofreqüència en un model porcí de pancreatectomia distal laparoscòpica (PDL). S’ha realitzat PDL en 10 animals avaluant com a variable principal el desenvolupament de FP i com a variables secundàries paràmetres relacionats amb l’aparició de complicacions intra o postoperatòries. Els resultats obtinguts suggereixen la factibilitat de la realització de la transecció pancreàtica mitjançant el dispositiu assistit per radiofreqüència.

Prominent use of distal 5’ transcription start sites and discovery of a large number of additional exons in ENCODE regions

This report presents systematic empirical annotation of transcript products from 399 annotated protein-coding loci across the 1% of the human genome targeted by the Encyclopedia of DNA elements (ENCODE) pilot project using a combination of 5' rapid amplification of cDNA ends (RACE) and high-density resolution tiling arrays. We identified previously unannotated and often tissue- or cell-line-specific transcribed fragments (RACEfrags), both 5' distal to the annotated 5' terminus and internal to the annotated gene bounds for the vast majority (81.5%) of the tested genes. Half of the distal RACEfrags span large segments of genomic sequences away from the main portion of the coding transcript and often overlap with the upstream-annotated gene(s). Notably, at least 20% of the resultant novel transcripts have changes in their open reading frames (ORFs), most of them fusing ORFs of adjacent transcripts. A significant fraction of distal RACEfrags show expression levels comparable to those of known exons of the same locus, suggesting that they are not part of very minority splice forms. These results have significant implications concerning (1) our current understanding of the architecture of protein-coding genes; (2) our views on locations of regulatory regions in the genome; and (3) the interpretation of sequence polymorphisms mapping to regions hitherto considered to be "noncoding," ultimately relating to the identification of disease-related sequence alterations.

Goal recognition over POMDPs: inferring the intention of a POMDP agent

Plan recognition is the problem of inferring the goals and plans of an agent from partial observations of her behavior. Recently, it has been shown that the problem can be formulated and solved usingplanners, reducing plan recognition to plan generation.In this work, we extend this model-basedapproach to plan recognition to the POMDP setting, where actions are stochastic and states are partially observable. The task is to infer a probability distribution over the possible goals of an agent whose behavior results from a POMDP model. The POMDP model is shared between agent and observer except for the true goal of the agent that is hidden to the observer. The observations are action sequences O that may contain gaps as some or even most of the actions done by the agent may not be observed. We show that the posterior goal distribution P(GjO) can be computed from the value function VG(b) over beliefs b generated by the POMDPplanner for each possible goal G. Some extensionsof the basic framework are discussed, and a numberof experiments are reported.

Síndrome del dolor regional complejo tipo I en las fracturas del extremo distal del radio

Introducción: Las fracturas distales de radio (FDR) presentan diferentes resultadosfuncionales siendo desfavorables entre el 24% y el 31% de los casos. Una de lascomplicaciones más frecuentes es el síndrome del dolor regional complejo tipo I(SDRC-I), cuyo origen es desconocido. Sólo el 20-30% de los pacientes recuperarán sugrado de funcionalidad anterior.Objetivos: Estimar la prevalencia de SDRC-I tras una FDR de acuerdo a cuatro tipos detratamiento.Métodos: estudio de una serie de casos retrospectivos. La población de referencia hansido los 391 trabajadores afiliados a una Mutua en Cataluña y diagnosticados deFDR tras una lesión por accidente laboral durante lo años 2008-2010.Los casos han sido trabajadores accidentados que tras una FDR desarrollaron el SDRCI.Como variable dependiente se ha utilizado el diagnóstico de SDRC-I; como variablesindependientes el tipo de tratamiento, la edad, el sexo, la ocupación y el mecanismo dela lesión.Resultados: el 19,7% de la muestra ha desarrollado SDRC-I, siendo esta prevalenciasuperior en los pacientes intervenidos mediante la técnica de tracción bipolar o conagujas de Kirschner; 29,17% y 30,56% respectivamente, que para aquellos en los quese ha realizado un tratamiento conservador o una intervención quirúrgica con placa en Ty tornillos; 15,92% y 15,79%.Conclusiones El tratamiento conservador y la técnica quirúrgica de fijación con placaen T y tornillos han dado una menor prevalencia de SDRC-I.Los mecanismos de lesión asociados a una mayor fuerza presentan fracturas másinestables y requieren un tratamiento quirúrgico. Los tratamientos conservadores sonlos más usados en edades mayores relacionados con fracturas estables.A nivel clínico se extrae una recomendación profiláctica con Vitamina C para evitar laaparición de SDRC-I sobre los pacientes de edad comprendida entre los 36 y los 55años, con mecanismo lesional de caída o caída desde altura, intervenidos con agujas de Kirschner o tracción bipolar.

What leads people to keep on e-learning? An empirical analysis of users' experiences and their effects on continuance intention

User retention is a major goal for higher education institutions running their teaching and learning programmes online. This is the first investigation into how the senses of presence and flow, together with perceptions about two central elements of the virtual education environment (didactic resource quality and instructor attitude), facilitate the user¿s intention to continue e-learning. We use data collected from a large sample survey of current users in a pure e-learning environment along with objective data about their performance. The results provide support to the theoretical model. The paper further offers practical suggestions for institutions and instructors who aim to provide effective e-learning experiences.
