Interpersonal Trust in Virtual Software Development Teams: A Systematic Mapping Study

Context: The progress of Information and Communication Technologies has greatly promoted the relationships among people of different geographical regions. Under this novel context, new settings of software development arise, known as virtual teams, a team of geographically dispersed developers. Objective: to assess the impact of virtual team’s interper-sonal trust on software development process. Method: We conducted a systematic mapping study of peer-reviewed literature up to August 2016. Results: We reviewed 41 primary studies. Some highlights are that virtual team effectiveness is the most affected aspect by the lacking of interpersonal trust, while face-to-face meeting is the most mentioned work strategy to mitigate this problem. Conclusions: This study corroborates the impact of interpersonal trust on virtual software development teams. We identified some work strategies but few advanced tools to mitigate the problems derived from the lack of interpersonal trust.Sociedad Argentina de Informática e Investigación Operativ

Congenital short QT syndrome: Landmarks of the newest arrhythmogenic cardiac channelopathy

Congenital or familial short QT syndrome is a genetically heterogeneous cardiac channelopathy without structural heart disease that has a dominant autosomal or sporadic pattern of transmission affecting the electric system of the heart. Patients present clinically with a spectrum of signs and symptoms including irregular palpitations due to episodes of paroxysmal atrialfibrillation, dizziness and fainting (syncope) and/or sudden cardiac death due to polymorphic ventricular tachycardia and ventricular fibrillation. Electrocardiographic (ECG) findings include extremely short QTc intervals (QTc interval ≤ 330 ms) not significantly modified with heart rate changes and T waves of great voltage witha narrow base. Electrophysiologic studies are characterized by significant shortening of atrial and ventricular refractory periods and arrhythmias induced by programmed stimulation. A few families have been identified with specific genotypes: 3 with mutations in potassium channels called SQT1 (Iks), SQT2 (Ikr) and SQT3 (Ik1). These 3 potassium channel variants are the “genetic mirror image” of long QT syndrome type 2, type 1 and Andersen-Tawil syndrome respectively because they exert opposite gain-of-function effects on the potassium channels in contrast to the loss-of-function of the potassium channels in the long QT syndromes. Three new variants with overlapping phenotypes affecting the slow inward calcium channels havealso been described. Finally, another variant with mixed phenotype affecting the sodium channel was reported. This review focuses the landmarks of this newest arrhythmogenic cardiac channelopathy on the main clinical, genetic, and proposed ECG mechanisms. In addition therapeutic options and the molecular autopsy of this fascinating primary electrical heart disease are discussed

The Consistency of Causal Quantum Geometrodynamics and Quantum Field Theory

We consider quantum geometrodynamics and parametrized quantum field theories in the framework of the Bohm-de Broglie interpretation. In the first case, and following the lines of our previous work [1], where a hamiltonian formalism for the bohmian trajectories was constructed, we show the consistency of the theory for any quantum potential, completing the scenarios for canonical quantum cosmology presented there. In the latter case, we prove the consistency of scalar field theory in Minkowski spacetime for any quantum potential, and we show, using this alternative hamiltonian method, a concrete example where Lorentz invariance of individual events is broken.Comment: Final version.

A 3D KINEMATICAL ANALYSIS OF LONG JUMP IN THE “GOLD MEETING RIO OF ATHLETICS 2007”

This study was based on the 3D kinematical analysis of long jump in an official competition of the International Association of Athletics Federation. A six camera kinematical analysis system was used to reconstruct the 3D coordinates of eighteen points, modeling the athlete’s body with the follow segments: head, trunk, arms, forearms, thighs, calves and feet. Several performance variables concerning the center of mass trajectories and velocities were used to characterize and compare the individual jumps. Descriptive statistics was used to compare the results obtained with those found in the literature

Medición de confianza interpersonal en equipos globales de desarrollo de software

El progreso alcanzado por las tecnologías de información y comunicación ha promovido fuertemente las relaciones o vinculaciones entre personas de distintos puntos geográficos del mundo. Bajo este novedoso contexto nuevas configuraciones de equipos de desarrollo de software surgen, conocidos como equipos virtuales. Un desafío en estos nuevos escenarios distribuidos es el entendimiento de los aspectos humanos y sociales involucrados en el proceso de desarrollo de software y su impacto en la efectividad del mismo. El objetivo del presente trabajo es identificar y clasificar conocimiento reportado acerca de la medición de confianza interpersonal en contextos globales de desarrollo de software. Para alcanzar ese objetivo se aplica un estudio de mapeo sistemático de la literatura científica.Eje: Ingeniería de Software.Red de Universidades con Carreras en Informátic
