Syntaxonomic conspectus of the vegetation of Catalonia and Andorra. I: Hygrophilous herbaceous communities.

The first part of a general survey of the vegetation of Catalonia andAndorra, this paper reports all the phytocoenological associations and subassociations recorded in this area. For each community, we provide the correct name and usual synonyms, its typification (where appropriate), all the references including relevés, and the most outstanding features of its structure, species composition, ecology, distribution and diversity. Moreover, associations and subassociations are ordered appropriately in a syntaxonomic scheme. Syntaxonomic ranks are considered in a fairly broad, conservative sense. This classification established 101 associations, which correspond to the classes Lemnetea, Zosteretea, Potametea, Littorelletea, Montio-Cardaminetea, Phragmiti-Magnocaricetea, Scheuchzerio-Caricetea, Isoeto-Nanojuncetea and Molinio-Arrhenatheretea.

La formació competencial dels llicenciats en economia i empresa: una visió des del seu entorn professional

La recerca que es presenta té com a objectiu enfocar una de les arrels de la manca de rendiment laboral dels treballadors: la formació que han rebut, en particular aquells que han seguit una trajectòria universitària. Per dur-ho a terme s"ha valorat l"encaix entre el marc didàctic i les competències que s"exigeixen als alumnes a l"hora d"incorporar-se al mercat de treball. S"ha partit d"una enquesta a persones acabades de llicenciar de la Facultat d"Economia de la Universitat de Barcelona, a docents d"aquesta mateixa Facultat i a empresaris. A partir dels resultats obtinguts s"ha fet una anàlisi de la situació dels joves treballadors en termes de competències instrumentals, interpersonals i professionals, centrada exclusivament en la percepció dels empresaris. Segons les conclusions, una planificació de la docència més centrada en l"estudiant, des del punt de vista de la seva formació integral, pot contribuir de forma essencial a incrementar la seva futura productivitat laboral.

Serveis d'informació professional

La elección de profesión es una de las decisiones más importantes que una persona debe tomar. De dicha elección dependen otros aspectos de la vida. La elección con conocimiento de causa debe estar precedida de una información detallada. Por eso la información profesional debería ser una actividad habitual en los centros educativos. La planificación de los servicios de información profesional tiene que seguir un proceso ordenado. En primer lugar es preciso conocer unas bases teóricas y metodológicas que fundamenten todo tipo de actividad. En segundo lugar es preciso realizar un estudio del contexto sociolaboral y del nivel educativo al cual va dirigido el programa de actividades de información profesional. De todo esto se derivan unas necesidades, tanto de parte de los alumnos como del centro y de los padres, que configuran unos objetivos a conseguir para satisfacer esas necesidades. Para la planificación de actividades encaminadas a conseguir objetivos, es preciso determinar unos contenidos sobre estudios, profesiones, estructura del sistema educativo, becas, etc. Es conveniente conocer las fuentes informativas; aplicar técnicas y conocer la situación del mundo laboral y el mercado de trabajo. Al final de un programa de actividades conviene evaluar lo que se ha hecho y su incidencia como feed-back para futuras experiencias.

Aquest article vol oferir un exemple de treball innovador basat en una recerca acció per a la construcció d'un procés educatiu orientat a l'acompanyament de l'alumnat en les pràctiques externes en l'ensenyament d'Educació Social de la Universitat de Barcelona. En primer terme, presentem els referents conceptuals en els quals s'emmarquen els aprenentatges del Pràcticum. En segon lloc, aprofundim en la metodologia de la recerca sobre la reflexió de la pràctica docent duta a terme en el marc d'un projecte d'innovació docent (2008MQD155) per analitzar, aclarir i promoure les competències i condicions necessàries perquè s'esdevingui el procés d'aprenentatge. Seguidament, es presenten com a resultat de la recerca uns quaderns adreçats als agents implicats en el procés del Pràcticum, que volen donar suport a la funció docent. Finalment, s'aporten conclusions, reflexions i interrogants sobre el que ha suposat l'elaboració conjunta dels quaderns de Pràcticum, amb el propòsit d'afavorir la transferència a altres realitats educatives d'educació superior.

Spatial pattern and process at the plant neighbourhood scale: insights from communities dominated by the clonal grass Elymus repens (L.) Gould.

Question: How do clonal traits of a locally dominant grass (Elymus repens (L.) Gould.) respond to soil heterogeneity and shape spatial patterns of its tillers? How do tiller spatial patterns constrain seedling recruitment within the community?Locations: Artificial banks of the River Rhone, France.Material and Methods: We examined 45 vegetation patches dominated by Elymus repens. During a first phase we tested relationships between soil variables and three clonal traits (spacer length, number of clumping tillers and branching rate), and between the same clonal traits and spatial patterns (i.e. density and degree of spatial aggregation) of tillers at a very fine scale. During a second phase, we performed a sowing experiment to investigate effects of density and spatial patterns of E. repens on recruitment of eight species selected from the regional species pool.Results: Clonal traits had clear effects - especially spacer length - on densification and aggregation of E. repens tillers and, at the same time, a clear response of these same clonal traits as soil granulometry changed. The density and degree of aggregation of E. repens tillers was positively correlated to total seedling cover and diversity at the finest spatial scales.Conclusions: Spatial patterning of a dominant perennial grass responds to soil heterogeneity through modifications of its clonal morphology as a trade-off between phalanx and guerrilla forms. In turn, spatial patterns have strong effects on abundance and diversity of seedlings. Spatial patterns of tillers most probably led to formation of endogenous gaps in which the recruitment of new plant individuals was enhanced. Interestingly, we also observed more idiosyncratic effects of tiller spatial patterns on seedling cover and diversity when focusing on different growth forms of the sown species.

Chaotic dynamics and team effectiveness: evidence from professional basketball

Considering teams as complex adaptive systems (CAS) this study deals with changes in team effectiveness over time in a specific context: professional basketball. The sample comprised 23 basketball teams whose outcomes were analysed over a 12-year period according to two objective measures. The results reveal that all the teams showed chaotic dynamics, one of the key characteristics of CAS. A relationship was also found between teams showing low-dimensional chaotic dynamics and better outcomes, supporting the idea of healthy variability in organizational behaviour. The stability of the squad was likewise found to influence team outcomes, although it was not associated with the chaotic dynamics in team effectiveness. It is concluded that studying teams as CAS enables fluctuations in team effectiveness to be explained, and that the techniques derived from nonlinear dynamical systems, developed specifically for the study of CAS, are useful for this purpose.

Aufftrittsangst : kardiorespiratorische Aktivität bei ängstlichen und nichtängstlichen Musikstudenten in einer Auftrittssituation = Performance anxiety : cardiorespiratory activity in high- and low-anxious professional music students in a performance situation

Fragebogenstudien haben gezeigt, dass ängstliche Musiker vor und/oder während eines Auftritts möglicherweise unter Hyperventilationssymptomen leiden. Berichtete Symptome beinhalten Kurzatmigkeit, schnelles oder tiefes Einatmen, Schwindelgefühl und Herzklopfen. Bisher hat jedoch noch keine Studie getestet, ob diese selbstberichteten Symptome tatsächlich kardiorespiratorische Veränderungen widerspiegeln. Das Hauptziel dieser Studie ist es, zu bestimmen, ob sich Auftrittsangst bei Musikern physiologisch über kardiorespiratorische Muster äußert. Wir haben insgesamt 74 Musikstudenten von Schweizer Musikhochschulen getestet. Diese Studenten wurden aufgrund ihrer selbstberichteten Auftrittsangst (STAI-S) in zwei Gruppen unterteilt: ängstliche Musiker und nichtängstliche Musiker. Die Studenten wurden in drei unterschiedlichen Situationen getestet: Ausgangszustand, Auftritt ohne Publikum, Auftritt mit Publikum. Wir haben folgende Parameter gemessen: a) kardiorespiratorische Muster und endexpiratorisches CO2, welches eine gute nichtinvasive Schätzung des Hyperventilationsgrades liefert und b) subjektiv wahrgenommene Emotionen und subjektiv wahrgenommene physiologische Aktivität. Das Poster zeigt die ersten Resultate der 15 ängstlichsten und der 15 am wenigsten ängstlichen Musiker. Das Hauptinteresse gilt den folgenden Punkten: Herz- und Atemfrequenz, subjektiv wahrgenommenes Herzklopfen, subjektiv wahrgenommene Kurzatmigkeit und subjektiv wahrgenommenes Angstgefühl. Die Resultate dieser Studie zeigen erstens, dass ängstliche und nichtängstliche Musikstudenten zu den verschiedenen Messzeitpunkten eine vergleichbare physiologische Aktivität aufweisen und zweitens, dass ängstliche Musikstudenten ein signifikant höheres Angstgefühl haben und signifikant mehr Herzklopfen und Kurzatmigkeit wahrnehmen vor und/oder während eines Auftritts mit Publikum. Dies deutet darauf hin, dass sich ängstliche und nichtängstliche Musikstudenten a) bezüglich der subjektiv wahrgenommenen physiologischen Symptome und des selbst berichteten Angstgefühls vor und/oder während eines öffentlichen Auftritts unterscheiden und sich b) bezüglich der untersuchten physiologischen Reaktionen nicht unterscheiden.

Does the generalist parasitic plant Cuscuta campestris selectively forage in heterogeneous plant communities?

Cuscuta spp. are holoparasitic plants that can simultaneously parasitise several host plants. It has been suggested that Cuscuta has evolved a foraging strategy based on a positive relationship between preuptake investment and subsequent reward on different host species. Here we establish reliable parasite size measures and show that parasitism on individuals of different host species alters the biomass of C. campestris but that within host species size and age also contributes to the heterogeneous resource landscape. We then performed two additional experiments to test whether C. campestris achieves greater resource acquisition by parasitising two host species rather than one and whether C. campestris forages in communities of hosts offering different rewards (a choice experiment). There was no evidence in either experiment for direct benefits of a mixed host diet. Cuscuta campestris foraged by parasitising the most rewarding hosts the fastest and then investing the most on them. We conclude that our data present strong evidence for foraging in the parasitic plant C. campestris.

Functional homogenization of bumblebee communities in alpine landscapes under projected climate change

Background: Bumblebees represent an active pollinator group in mountain regions and assure the pollination of many different plant species from low to high elevations. Plant-pollinator interactions are mediated by functional traits. Shift in bumblebee functional structure under climate change may impact plant-pollinator interactions in mountains. Here, we estimated bumblebee upward shift in elevation, community turnover, and change in functional structure under climate change. Method: We sampled bumblebee species at 149 sites along the elevation gradient. We used stacked species distribution models (S-SDMs) forecasted under three climate change scenarios (A2, A1B, RCP3PD) to model the potential distribution of the Bombus species. Furthermore, we used species proboscis length measurements to assess the functional change in bumblebee assemblages along the elevation gradient. Results: We found species-specific response of bumblebee species to climate change. Species differed in their predicted rate of range contraction and expansion. Losers were mainly species currently restricted to high elevation. Under the most severe climate change scenarios (A2), we found a homogenization of proboscis length structure in bumblebee communities along the elevation gradient through the upward colonization of high elevation by species with longer proboscides. Conclusions: Here, we show that in addition to causing the shift in the distribution of bumblebee species, climate change may impact the functional structure of communities. The colonization of high elevation areas by bumblebee species with long proboscides may modify the structure of plant-pollination interaction networks by increasing the diversity of pollination services at high elevation.

Evaluation of Gateway and Low-Cost Traffic-Calming Treatments for Major Routes in Small, Rural Communities, TR-523, 2007

Many rural communities have developed around highways or major county roads; as a result, the main street through small rural communities is often part of a high-speed rural highway. Highways and county roads are characterized by high speeds outside the city limits; they then transition into a reduced speed section through the rural community. Consequently, drivers passing through the community often enter at high speeds and maintain those speeds as they travel through the community. Traffic calming in small rural communities along major roadways is common in Europe, but the U.S. does not have experience with applying traffic-calming measures outside of major urban areas. The purpose of the project was to evaluate traffic-calming treatments on the major road through small Iowa communities using either single-measure low-cost or gateway treatments. The project was partially funded by the Iowa Highway Research Board (IHRB). The focus of the IHRB portion was to evaluate single-measure, low-cost, traffic-calming measures that are appropriate to major roads through small rural communities. Seven different low-cost traffic treatments were implemented and evaluated in five rural Iowa communities. The research evaluated the use of two gateway treatments in Union and Roland; five single-measure treatments (speed table, on-pavement “SLOW” markings, a driver speed feedback sign, tubular markers, and on-pavement entrance treatments) were evaluated in Gilbert, Slater, and Dexter.
