Sports and journalism ethics: the coverage of 2012 London Olympics in the British, North-American and Spanish press

Sports and journalism ethics: the coverage of 2012 London Olympics in the British, North-American and Spanish press is a research focused on analysing the treatment that the quality press of three countries (United Kingdom, United States of America and Spain) will carry out in the London Olympic Games. Through a solid methodological approach based on the combination of the qualitative content analysis and qualitative indepth interviews, the investigation will study if the media provide a quality coverage,that is, if they adequate their pieces to the fundamental principles of journalistic deontology (truth, justice, freedom and social responsibility). Furthermore, the research will assess if the selected media comply with the prescriptions established in the ethical codes, stylebooks, newsroom statutes and national and international recommendations about journalism ethics, ranging from each media’s guidelines to key transnational codes established by the UNESCO, the International Federation of Journalists (IFJ) orthe Council of Europe.

Life-time growth patterns of pumpkinseed Lepomis gibbosus introduced to Europe, relative to North American populations

The pumpkinseed Lepomis gibbosus, an omnivorous, nest guarding North American sunfish, was introduced into European waters about 100 years ago. To assess growth performance following introduction, we reviewed the available data for North American and European populations of pumpkinseed and compared the back-calculated age-specific growth for juveniles (standard length, SL, at age two) and adults (age two to five increment) as well as adult body size (SL at age five), von Bertalanffy growth model parameters and the index of growth (in length) performance (φ′). For continental comparisons of growth trajectory, mean growth curves for North American and Europe were calculated with the von Bertalanffy model using pooled data sets for each continent. Juvenile growth rate did not differ between European and North American pumpkinseed, but mean adult body size and adult growth rate were both significantly greater in North American than European populations. Adult body size decreased with increasing latitude (ANOVA) in North American populations, but this was not observed with adult growth rate. In contrast, adult body size tended to increase with latitude in European populations. Adult body size correlated significantly with φ′. The von Bertalanffy model described the overall growth patterns of North American and European populations reasonably well, but on the individual population level, length asymptotes were unrealistic (estimates that were > 20 % of the mean back-calculated size for the oldest age class) for a third of European populations and 80% of the North American populations. In contrast to North American pumpkinseed populations, somatic growth in European populations appears to be compromised by limited, but adequate, food resources, probably due to strong intraspecific interactions. This appears to be especially acute in adults, having potential ramifications for life span and reproductive allocation

Faculty and Student Perspectives Toward Open Courseware, and Open Access Publishing: Some Comparisons Between European and North American Populations

Instructor and student beliefs, attitudes and intentions toward contributing to local open courseware (OCW) sites have been investigated through campus-wide surveys at Universidad Politecnica de Valencia and the University of Michigan. In addition, at the University of Michigan, faculty have been queried about their participation in open access (OA) publishing. We compare the instructor and student data concerning OCW between the two institutions, and introduce the investigation of open access publishing in relation to open courseware publishing.

On the origin of the North Pacific arcs

We present a new hypothesis that relates global plate tectonics to the formation of marginal basins, island arcs, spreading ridges and arc-shaped mountain belts around the North Pacific Ocean. According to our model, the ellipsoidal-shaped Paleogene basins of the South China Sea, Parece-Vela Basin, Shikoku Basin, Sea of Japan and the Sea of Okhotsk in addition to those of the North American Cordillera can be attributed to the change in plate convergence direction at 42 Ma between the Indoaustralian and Eurasian plates. The new direction of convergence was parallel to the eastern continental margin of Asia and resulted in widespread extension perpendicular to this margin and to the western margin of North America. Both margins form part of a circle parallel to the Indoaustralian-Eurasian direction of convergence.

El Derecho norteamericano como impulsor de la responsabilidad civil del fabricante por productos defectuosos

Investigación elaborada a partir de una estancia en la Columbia Law School of New York, Estados Unidos, entre los meses de septiembre y noviembre del 2006. El Derecho comunitario europeo y español regulan la reparación de los daños causados por el uso o la proximidad de un producto defectuoso mediante gracias al impulso ideológico ejercido por la jurisprudencia norteamericana. El principio de responsabilidad objetiva rector de la directiva europea es fruto de un transfondo operado en los Estados Unidos en los años sesenta, coincidiendo con la revolución tecnològica y el inicio de la producción y del consumo masivos. Tales fenómenos suscitaron la búsqueda de mecanismos jurídicos aptos para canalizar la reparación de los daños inherentes a las actividades industriales tecnológicamente avanzadas. Su principal efecto fue la preocupación por una más justa distribución social de los llamados “costes del progreso”, preocupación que, jurídicamente, desembocó en la solución de la responsabilidad aun sin culpa del fabricante por los daños derivados de su producción industrial. El mérito de tal solución corresponde a determinados teóricos norteamericanos de la responsabilidad empresarial, quienes, inspirándose en ideas formuladas a inicios del siglo XX por los especialistas en Derecho laboral, concluyeron que es la empresa productora quien está en mejor situación de soportar el coste del accidente industrial: al imponerse al fabricante una responsabildad desvinculada de su eventual culpa en la causación del accidente, repercutirá en el precio de sus productos el coste del seguro de responsabilidad civil que se verá abocado a contratar para hacer frente a su responsabilidad objetiva o por riesgo, de manera que el coste de los accidentes acabará siendo soportado por el público consumidor al pagar el sobreprecio de los productos que adquiere. Las repercusiones de tal construcción han sido tanto normativas como judiciales.

Impacte de la variabilitat climàtica ràpida de l'últim període glacial sobre la vegetació del sud-est de Nord Amèrica

Projecte de recerca elaborat a partir d’una estada a UMR-CNRS - Géologie et Océanographie, França, entre 2007 i 2009. Els canvis climàtics ràpids de l’últim període glacial (cicles Dansgaard/Oeschger i Heinrich Stadials-HS), han estat documentats en testimonis marins, de gel i dipòsits continentals, generalment de l’hemisferi nord. Mentre que la majoria dels estudis paleoclimàtics i paleoceanogràfics de l’Atlàntic Nord sobre l’últim període glacial s’han centrat en la part nord i est, les latituds mitjanes de la part occidental han estat menys estudiades. Particularment, els canvis de la vegetació de l’est de Nord Amèrica durant l’últim glacial es coneixen molt poc degut a la manca de seqüències pol.líniques llargues en aquesta regió. Només dues seqüències de pol.len del llac Tulane (Florida) mostren canvis de la vegetació significatius i interessants durant l’últim glacial, que suggereixen HS càlids i humits, que contrasta amb el que s’observa a l’altre costat de l’Atlàntic Nord. El treball realitzat al UMR-CNRS 5805 EPOC, Université Bordeaux 1, EPHE, des del 23 d’abril 2007 al 22 d’abril 2009, gràcies a la beca Beatriu de Pinós, implica una reconstrucció a alta resolució dels canvis de la vegetació a partir de l’anàlisi d’un testimoni marí, localitzat a l’oest de l’Atlàntic Nord subtropical (MD99-2203, 34º58’N, 75º12’W), durant l’Estadi Isotòpic Marí 3 (MIS 3). Les dades pal.linològiques del testimoni mostren una alternança entre Picea i Quercus. En general, les associacions pol.líniques indiquen que les variacions de la vegetació segueixen un patró bosc boreal/temperat durant l’últim glacial. El model d’edat preliminar basat en edats radiomètriques suggereix un augment del bosc temperat acompanyat d’una reducció del boreal entre el H4 i el H3. La comparació amb registres pol.línics marins d’alta resolució de la regió est subtropical, a latituds similars, mostren, per primer cop, que els canvis en les formacions forestals associats als canvis climàtics ràpids de l’últim glacial van ser menys intensos al sud-est de Nord Amèrica que a la Península Ibèrica.

Viatge als país dels somnis...perduts? : Aspectes de la sociabilitat nord-americana

Els objectius finals són diversos: comprovar els diferents punts de vista i les diferents perspectives socials dels autors esmentats, comparar-los amb les situacions reals que es donen cada dia, mirar d'esbrinar el perquè d'aquestes situacions, fer un estudi comparatiu des del punt de vista d'un europeu que visita els Estats Units i, sobretot, mirar d'entendre què porta els nord-americans a comportar-se d'aquesta manera i què porta autors com Leavitt i Ellis a reproduir o desdibuixar els trets més significatius de la societat nord-americana.

Visions del Corredor de la Mort

L'objectiu principal d'aquest treball és analitzar si hi ha modificacions i/o canvis en la identitat dels presoners nord-americans quan entren en el corredor de la mort en el període 2000- 2003. En cas afirmatiu, el treball que presento vol esbrinar-ne les possibles causes. L'objectiu secundari és determinar si es pot parlar de l'existència de mecanismes psicosocials i polítics aplicats de manera sistemàtica o bé es tracta d'un seguit de reaccions i hàbits gairebé inconscients de les parts implicades.

Linguistic and maternal genetic diversity are not correlated in native mexicans

Mesoamerica, defined as the broad linguistic and cultural area from middle southern Mexico to Costa Rica, might have played a pivotal role during the colonization of theAmerican continent. It has been suggested that the Mesoamerican isthmus could have played an important role in severely restricting prehistorically gene flow between North and SouthAmerica. Although the Native American component has been already described in admixedMexican populations, few studies have been carried out in native Mexican populations. In thisstudy we present mitochondrial DNA (mtDNA) sequence data for the first hypervariable region (HVR-I) in 477 unrelated individuals belonging to eleven different native populations from Mexico. Almost all the Native Mexican mtDNAs could be classified into the four pan-Amerindian haplogroups (A2, B2, C1 and D1); only three of them could be allocated to the rare Native American lineage D4h3. Their haplogroup phylogenies are clearly star-like, as expected from relatively young populations that have experienced diverse episodes of genetic drift (e.g. extensive isolation, genetic drift and founder effects) and posterior population expansions. In agreement with this observation is the fact that Native Mexican populations show a high degree of heterogeneity in their patterns of haplogroup frequencies. HaplogroupX2a was absent in our samples, supporting previous observations where this clade was only detected in the American northernmost areas. The search for identical sequences in the American continent shows that, although Native Mexican populations seem to show a closer relationship to North American populations, they cannot be related to a single geographical region within the continent. Finally, we did not find significant population structure on the maternal lineages when considering the four main and distinct linguistic groups represented in our Mexican samples (Oto-Manguean, Uto-Aztecan, Tarascan, and Mayan), suggesting that genetic divergence predates linguistic diversification in Mexico.

Urban mobilities: the anglo-catalan production of the Barcelona model

The aim of the project was to gauge the extent to which the so-called ‘Barcelona Model’ of urban transformation has been ‘exported’ to Britain and whether Barcelona has learned from British cities. We engage with the literature on successive British governments’ strategies for cities, focused on collecting data on contemporary policy initiatives and debates in the UK, did interviews in Manchester, London Barcelona and participated in the official visit of Leeds to Barcelona in March. Our research findings to date suggest that there is a good deal of mobility and interaction between Barcelona and the UK. However, it is by no means certain that this has resulted in definite instances of policy transfer. While the ‘Barcelona model’ has indeed featured in oficial discourse on urban regeneration in the UK, it does not appear to be the preferred best practice ‘model’ – other North American and European cities figure discursively as much, if not more. Where Barcelona does feature in official discourse, it is usually as an example of good design and an appealing urban aesthetic, rather than in terms of economic or social policy best practice. Our research suggests that the Barcelona model is seen as non-transferable to the UK due to the relatively more centralised governance structure therein.In contrast, evidence collected suggests that the Barcelona model is not influenced by UK British cities experiences but there is small evidence of being influenced by UK-based professionals.

Teaching, research and service: Experience and opinions of accounting Spanish academics

Research, teaching and service are the main activities carried out in almost all European universities. Previous research, which has been mainlycentred in North-American universities, has found solid results indicatingthat research and teaching are not equally valued when deciding on facultypromotion. This conclusion creates a potential conflict for accountingacademics on how to distribute working time in order to accomplish personalcareer objectives. This paper presents the results of a survey realisedin two European countries: Spain and the United Kingdom, which intendedto explore the opinions and personal experience of accounting academicsworking in these countries. Specifically, we focus on the following issues:(i) The impact of teaching and service on time available for research;(ii) The integration of teaching and research; (iii) The perceived valueof teaching and research for career success and (iv) The interaction betweenprofessional accounting and accounting research. The results show thatboth in Spain and in the United Kingdom there is a conflict between teachingand research, which has its origin in the importance attached to researchactivities on promotion decisions. It also seems evident that so far, theconflict is being solved in favour of research in prejudice of teaching.

Contribution of microbial and invertebrate communities to leaf litter colonization in a Mediterranean stream

Leaf litter inputs and retention play an important role in ecosystem functioning in forested streams. We examined colonization of leaves by microbes (bacteria, fungi, and protozoa) and fauna in Fuirosos, an intermittent forested Mediterranean stream. Black poplar (Populus nigra) and plane (Platanus acerifolia) leaf packs were placed in the stream for 4 mo. We measured the biomasses and calculated the densities of bacteria, fungi, protozoa, meiofauna, and macroinvertebrates to determine their dynamics and potential interactions throughout the colonization process. Colonization was strongly correlated with hydrological variability (defined mainly by water temperature and discharge). The 1st week of colonization was characterized by hydrological stability and warm water temperatures, and allocation of C from microbial to invertebrate compartments on the leaf packs was rapid. Clumps of fine particulate organic matter (FPOM) were retained by the leaf packs, and enhanced rapid colonization by microfauna and meiofaunal collector-gatherers (ostracods and copepods). After 2 wk, an autumnal flood caused a 20-fold increase in water flow. Higher discharge and lower water temperature caused FPOM-related fauna to drift away from the packs and modified the subsequent colonization sequence. Fungi showed the highest biomass, with similar values to those recorded at the beginning of the experiment. After 70 d of postflood colonization, fungi decreased to nearly 40% of the total C in the leaf packs, whereas invertebrates became more abundant and accounted for 60% of the C. Natural flood occurrence in Mediterranean streams could be a key factor in the colonization and processing of organic matter.

Effects of riparian vegetation removal on nutrient retention in a Mediterranean stream

We examined the effects of riparian vegetation removal on algal dynamics and stream nutrient retention efficiency by comparing NH4-N and PO4-P uptake lengths from a logged and an unlogged reach in Riera Major, a forested Mediterranean stream in northeastern Spain. From June to September 1995, we executed 6 short-term additions of N (as NH4Cl) and P (as Na2HPO4) in a 200-m section to measure nutrient uptake lengths. The study site included 2 clearly differentiated reaches in terms of canopy cover by riparian trees: the first 100 m were completely logged (i.e., the logged reach) and the remaining 100 m were left intact (i.e., the shaded reach). Trees were removed from the banks of the logged reach in the winter previous to our sampling. In the shaded reach, riparian vegetation was dominated by alders (Alnus glutinosa). The study was conducted during summer and fall months when differences in light availability between the 2 reaches were greatest because of forest canopy conditions. Algal biomass and % of stream surface covered by algae were higher in the logged than in the shaded reach, indicating that logging had a stimulatory effect on algae in the stream. Overall, nutrient retention efficiency was higher (i.e., shorter uptake lengths) in the logged than in the shaded reach, especially for PO4-P. Despite a greater increase in PO4-P retention efficiency relative to that of NH4-N following logging, retention efficiency for NH4-N was higher than for PO4-P in both study reaches. The PO4-P mass-transfer coefficient was correlated with primary production in both study reaches, indicating that algal activity plays an important role in controlling PO4-P dynamics in this stream. In contrast, the NH4-N mass-transfer coefficient showed a positive relation-ship only with % of algal coverage in the logged reach, and was not correlated with any algal-related parameter in the shaded reach. The lack of correlation with algal production suggests that mechanisms other than algal activity (i.e., microbial heterotrophic processes or abiotic mechanisms) may also influence NH4-N retention in this stream. Overall, this study shows that logging disturbances in small shaded streams may alter in-stream ecological features that lead to changes in stream nutrient retention efficiency. Moreover, it emphasizes that alteration of the tight linkage between the stream channel and the adjacent riparian zone may directly and indirectly impact biogeochemical processes with implications for stream ecosystem functioning.

A comparison of rapid bioassessment protocols used in 2 regions with Mediterranean climates, the Iberian Peninsula and South Africa

Abstract. The ability of 2 Rapid Bioassessment Protocols (RBPs) to assess stream water quality was compared in 2 Mediterranean-climate regions. The most commonly used RBPs in South Africa (SAprotocol) and the Iberian Peninsula (IB-protocol) are both multihabitat, field-based methods that use macroinvertebrates. Both methods use preassigned sensitivity weightings to calculate metrics and biotic indices. The SA- and IB-protocols differ with respect to sampling equipment (mesh size: 1000 lm vs 250 300 lm, respectively), segregation of habitats (substrate vs flow-type), and sampling and sorting procedures (variable time and intensity). Sampling was undertaken at 6 sites in South Africa and 5 sites in the Iberian Peninsula. Forty-four and 51 macroinvertebrate families were recorded in South Africa and the Iberian Peninsula, respectively; 77.3% of South African families and 74.5% of Iberian Peninsula families were found using both protocols. Estimates of community similarity compared between the 2 protocols were .60% similar among sites in South Africa and .54% similar among sites in the Iberian Peninsula (BrayCurtis similarity), and no significant differences were found between protocols (Multiresponse Permutation Procedure). Ordination based on Non-metric Multidimensional Scaling grouped macroinvertebrate samples on the basis of site rather than protocol. Biotic indices generated with the 2 protocols at each site did not differ. Thus, both RBPs produced equivalent results, and both were able to distinguish between biotic communities (mountain streams vs foothills) and detect water-quality impairment, regardless of differences in sampling equipment, segregation of habitats, and sampling and sorting procedures. Our results indicate that sampling a single habitat may be sufficient for assessing water quality, but a multihabitat approach to sampling is recommended where intrinsic variability of macroinvertebrate assemblages is high (e.g., in undisturbed sites in regions with Mediterranean climates). The RBP of choice should depend on whether the objective is routine biomonitoring of water quality or autecological or faunistic studies.

Benthic macroinvertebrates assemblages and macrohabitat connectivity in Mediterranean-climate streams of northern California

Abstract. Drought leads to a loss of longitudinal and lateral hydrologic connectivity, which causes direct or indirect changes in stream ecosystem properties. Changes in macrohabitat availability from a rifflepool sequence to isolated pools are among the most conspicuous consequences of connectivity loss. Macroinvertebrate assemblages were compared among 3 distinct stream macrohabitats (riffles [R], pools connected to riffles [Pc], disconnected pools [Pd]) of 19 Mediterranean-climate sites in northern California to examine the influence of loss of habitat resulting from drought disturbance. At the time of sampling, 10 sites were perennial and included R and Pc macrohabitats, whereas 9 sites were intermittent and included only Pd macrohabitats. Taxa richness was more variable in Pd, and taxa richness was significantly lower in Pd than in Pc but not R. These results suggested a decline in richness between Pc and Pd that might be associated with loss of connectivity. Lower Ephemeroptera, Plecoptera, and Trichoptera (EPT) richness relative to Odonata, Coleoptera, and Heteroptera (OCH) richness was observed for Pd than R and Pc macrohabitats. Family composition was more similar between R and Pc than between R or Pc and Pd macrohabitats. This similarity may be associated with greater connectivity between R and Pc macrohabitats. Correspondence analysis indicated that macroinvertebrate composition changed along a gradient from R to Pc and Pd that was related to a perennialintermittent gradient across sites. High variability among macroinvertebrate assemblages in Pd could have been related to variability in the duration of intermittency. In cluster analysis, macroinvertebrate assemblages were grouped by macrohabitat first and then by site, suggesting that the macrohabitat filter had a greater influence on macroinvertebrate assemblages than did local site characteristics. Few taxa were found exclusively in Pc, and this macrohabitat shared numerous taxa with R and Pd, indicating that Pc may act as a bridge between R and Pd during drought. Drought is regarded as a ramp disturbance, but our results suggest that the response of macroinvertebrate assemblages to the loss of hydrological connectivity among macrohabitats is gradual, at least in Mediterranean-climate streams where drying is gradual. However, the changes may be more dramatic in arid and semiarid streams or in Mediterranean-climate streams if drying is rapid.
