El voluntariado universitario como una expresión del altruismo:

University volunteering represents a form of altruism; this behavioral expression typifies the social cognitions about groups or individuals and the motivational focuses of each person. Including volunteering into the academic experience would guarantee professionals who are committed to the search of a common benefit, to the protection of vulnerable groups and social integration. We are observing a growing number of institutions betting on creating volunteering spaces into their installations, as in the case of the University of Panama. Organizations such as AIESEC Panama and the IEEE (Institute of Electrical and Electronics Engineers) are generating joint projects to further enrich their professional experience and guarantee community awareness, allowing them to return the accumulation of knowledge being acquired.El voluntariado universitario representa una forma de altruismo; esta expresión comportamental tipifica las cogniciones sociales sobre los grupos o individuos y los focos motivacionales de cada persona. Incluir al voluntariado universitario en la experiencia académica garantizaría profesionales comprometidos en la búsqueda de un beneficio común, la protección de grupos vulnerables y la integración social. Se observa un creciente número de instituciones apostando en crear espacios de voluntariado dentro de sus instalaciones, tal es el caso de la Universidad de Panamá, organizaciones como AIESEC Panamá y la IEEE (Instituto de Ingenieros Eléctricos y Electrónicos) están generando proyectos en común enriqueciendo la experiencia profesional y garantizando conciencia comunitaria, permitiéndoles devolver el cúmulo de conocimientos adquiridos

Influence of environmental factors on the reproductive cycle of the eared ark Anadara notabilis (Röding, 1798) in Northeastern Venezuela

5 figuras, 2 tablasThe reproductive cycle of the eared ark Anadara notabilis and its relationship with environmental factors was evaluated every 15 days between March 2004 and February 2005 at the northern part of the Peninsula de Araya, Venezuela. Environmental factors measured included temperature, salinity, chlorophyll a, and total seston, including the particulate organic matter and particulate inorganic matter fractions. Adult specimens were collected using a net drag and then randomly selected to estimate wet live biomass and dry biomass of soft body tissues. Gonad samples were processed with histological analysis to determine sex ratio, developmental stages, and variations of follicle size. Reproduction in A. notabilis was continuous throughout the year, with spawning peaks occurring in June and October, coinciding with the lowest water temperatures. In March, September, and November 2004, specimens attained the highest dry biomass values, whereas lowest dry biomass occurred in June and October 2004. Stepwise regression analyses demonstrated that temperature and particulate organic matter values are the main modulators of reproductive events. When temperature decreased, dribble spawning was detected in this species, possibly inducing a survival strategy whereby the spawning period is extended to increase reproductive successPeer reviewe

Single Multiplex Polymerase Chain Reaction To Detect Diverse Loci Associated with Diarrheagenic Escherichia coli

We developed and tested a single multiplex polymerase chain reaction (PCR) that detects enterotoxigenic, enteropathogenic, enteroinvasive, and Shiga-toxin–producing Escherichia coli. This PCR is specific, sensitive, and rapid in detecting target isolates in stool and food. Because of its simplicity, economy, and efficiency, this protocol warrants further evaluation in large, prospective studies of polymicrobial substances

Homelessness in urban communities in the US: A Scoping Review utilizing the Socio-Ecological Model

Homelessness remains a core element of the current housing stability crisis in the United States, especially in urban communities. Disparities are an important part of the pathway to homelessness, but they alone are not enough to generate and perpetuate homelessness in the US. Therefore, it is crucial to analyze existing literature to provide an evidence-based framework to help inform homeless-related policies, programs, and interventions to improve the quality of life for homeless individuals. This scoping review aims to map the last five years\u27 literature around homelessness in U.S. urban communities by utilizing the socioecological model to analyze system-based implicated factors. The PubMed database was used to search articles from 2016 to 2020. Included articles were based in the United States at urban communities involving homeless individuals or families. A total of 145 articles were found for screening. Forty-nine articles met the selection criteria. A Florida-based university street medicine team involved in this research project highlights the need for an interprofessional approach to homelessness. The results of this scoping review suggest that structural, systemic, and historical factors at all the levels of the socioecological model are implicated in the complex reality of homelessness in U.S. urban communities generating individual and collective disparities. Future research and practice need to elucidate the impact of intersectionality among factors associated with homelessness

The Spatial Distribution of Fluorescent H2_2 Near T Tau

New subarcsecond FUV observations of T Tau with HST/STIS show spatially resolved structures in the 2"x2" area around the star. The structures show in multiline emission of fluorescent H_2 pumped by Lyman alpha. One emission structure follows the cavity walls observed around T Tau N in scattered light in the optical. A temperature greater or equal to 1000K is required to have enough population in the H_2 to produce the observed fluorescent lines; in the cool environment of the T Tau system, shock heating is required to achieve this temperature at distances of a few tens of AU. Fluorescent H_2 along the cavity wall represents the best evidence to date for the action of low-density, wide-opening-angle outflows driving cavities into the molecular medium at scales smaller than 100 AU. A southern region of emission consists of two arcs, with shape and orientation similar to the arcs of H_2 2.12 microns and forbidden line emission crossing the outflow associated with the embedded system T Tau S. This region is located near the centroid of forbidden line emission at the blueshifted lobe of the N-S outflow.Comment: To appear in ApJ, vol. 591.

Facilitated advancement of the Palmaz-Schatz stent delivery system with the use of an adjacent 0.018′ stiff wire

The 5.0 French Palmaz-Schatz stent delivery system is a relatively bulky, stiff system which can be advanced only over a 0.014′ wire. Although crossing failure is rare, advancement of the delivery system through tortuous, rigid vessels may be unsuccessful. We report on four consecutive cases in which the initial advancement of the Palmaz-Schatz stent delivery system was unsuccessful due to vessel tortuosity or vessel angulation. The use of a 0.018′ stiff wirer adjacent to the Palmaz-Schatz delivery system, to “straighten” the vessels and to give additional guide catheter support, allowed for the successful advancement and delivery of coronary stents in all four cases. © 1996 Wiley-Liss, Inc.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/38223/1/24_ftp.pd

Decision making in fencing training and its relationship with reaction time

En la esgrima, se plantean tareas orientadas a desarrollar el mecanismo de percepción, el de decisión y/o el de ejecución. Una forma de saber en qué medida se incide más en uno u otro es medir el Tiempo de Reacción, y a partir de él hacer inferencias sobre el efecto de las variables manipuladas en la investigación sobre cada uno de los mecanismos. Por otro lado, nos puede ayudar a determinar el nivel de capacidad perceptiva y de toma de decisiones de un esgrimista. Los objetivos planteados en este estudio fueron, conocer si existen diferencias en cuanto a la percepción y toma de decisiones en función del arma practicada y determinar con qué acciones se dificulta la percepción y la toma de decisiones en esgrima. Los sujetos fueron 18 miembros del equipo nacional de esgrima, que se colocaron frente a una pantalla en la que se proyectaban vídeos en los que aparecía el entrenador de cada arma realizando acciones a las que los esgrimistas debían reaccionar lo antes posible. Los resultados mostraron diferencias significativas del grupo de espadistas con los floretistas y sablistas. Por otro lado, se pudo constatar que la tarea que más tiempo requiere para tomar la decisión al tirador es discernir si un ataque lanzado por el contrario está bien o mal ejecutado.In fencing, certain tasks are designed to develop the mechanism of perception, decision and/ or execution. One way to know the effect to one or another is to measure the Reaction Time, making inferences about the effect of the manipulated variables in the research about the mechanisms. On the other hand, Reaction Time can help us to determine the level of perceptual ability and decision making of a fencer. The objectives of this study were, test the differences in perception and decision making depending on the weapon, and determine what actions are more difficult to perception and decision making in fencing. The subjects were 18 members of the spanish national fencing team. Fencers were placed facing a screen in which videos were projecting appearing the coach of each weapon launching actions to which the fencers had to react quickly. The results showed significant differences between the epeeists and the foil and sabre fencers. On the other hand, it was found more time is required to make the decision is to distinguish if the opponent´s attack had a good or bad execution.peerReviewe
