Anàlisi del grau de coneixement d'aspectes relacionats amb l'activitat física i la salut que tenen les dones de 30 a 45 anys de Vallromanes

L’objectiu de l’estudi és identificar el grau de coneixement que tenen les dones de 30 a 45 anys del municipi de Vallromanes sobre aspectes relacionats amb l’activitat física i la salut, així com identificar quins coneixements són més específics perquè s’adhereixin a la pràctica regular d’activitat física. A més, de comprovar quins d’aquests possibles coneixements relacionats a la promoció de la salut pública són més eficients per fer augmentar el coneixement d’aquest grup de dones i alhora fer-les conscients de la importància de l’activitat física per la salut. Així doncs, a la mostra de l’estudi han participat 35 dones. La informació ha estat recopilada a través del qüestionari per identificar els estadis de canvi de l’activitat física (Marcus, Rossi, Selby, Niaura, i Abrams, 1992) i un qüestionari elaborat específicament per aquesta investigació. Els resultats obtinguts demostren, a trets generals, que les dones que es troben en estadis de canvi on tenen conductes actives físicament o compleixen amb les recomanacions mundials d’activitat física per la salut, tenen un major grau de coneixença i conscienciació sobre coneixements relacionats amb l’activitat física i la salut. Per tant, això porta a concloure que l’augment del coneixement i conscienciació d’aquest és un motiu perquè les dones participants en l’estudi s’adhereixin a la pràctica regular d’activitat física. No obstant, cal tenir present quines estratègies de salut pública són més específiques i eficients per fer augmentar el coneixement del grup de dones estudiat i adherir-les a la pràctica.

Evaluation of a snow avalanche possibly triggered by a local earthquake at Vallée de la Sionne, Switzerland

Snow avalanches are moving sources of infrasonic and seismic energy. They can be triggered by many different mechanisms that include the shaking produced by earthquakes. The forces induced by an earthquake can cause an increase in the load down the slope and can also decrease the shear strength and both effects can cause the release of an avalanche. This phenomenon represents an important hazard associated with earthquakes in snow-covered mountain areas with high seismicity.

Incumbent audit firm-provided tax services and the clients with low financial reporting quality

This study investigates whether incumbent audit firm-provided tax services enhance or impair the likelihood of acknowledging client companies’ low financial reporting quality. In particular, we examine the association between tax-related fees and the likelihood of timely restatements, and internal control weakness disclosures among a sample of US companies that all have misstatements in financial information. The empirical findings indicate that companies paying higher tax-related fees are less likely to disclose SOX 404 internal control weakness disclosures, implying that underlying control problems are unacknowledged when incumbent audit firm provided tax-related fees are higher. However, the findings suggest that just providing both audit and tax-related services does not have an impact on audit quality per se, but rather it is the magnitude of the tax-related fees in particular that counts. We also find some evidence suggesting that companies paying higher tax-related fees have higher likelihood of restatement lags, whereas companies paying smaller tax-related fees to their audit firm restate financial statements in a timelier manner. Overall, the findings suggest that audit scrutiny of client companies with low quality financial reporting is weaker when the magnitude of tax-related fees is higher.

Effect of magnesium sulphate and L-tryptophan and genotype on the feed intake, behaviour and meat quality of pigs

Sixty-nine entire male pigs with different halothane genotype (homozygous halothanepositive – nn-, n=36; and homozygous halothane negative – NN-, n=33) were fed with a supplementation of magnesium sulphate (Mg) and/or L-tryptophan (Trp) in the diet for 5days before slaughter. Animals were housed individually and were submitted to stressful ante mortem conditions (mixed in the lorry according to treatments and transported 1h on rough roads). Individual feed intake was recorded during the 5-day treatment. At the abattoir, pig behaviour was assessed in the raceway to the stunning system and during the stunning period by exposure to CO2. Muscle pH, colour, water holding capacity, texture and cathepsin activities were determined to assess meat quality. The number of pigs with an individual feed intake lower than 2kg/day was significantly different among diets (P<0.05; Control: 8.7%; Mg&Trp: 43.5%; Trp:17.4%) and they were considered to have inadequate supplement intake. During the antemortem period, 15.2% of pigs included in the experiment died, and this percentagedecreased to 8.7% in those pigs with a feed intake > 2kg/day, all of them from thestress-sensitive pigs (nn). In general, no differences were observed in the behaviour ofpigs along the corridor leading to the stunning system and inside the CO2 stunningsystem. During the stunning procedure, Trp diet showed shorter periods of muscularexcitation than control and Mg&Trp diets. The combination of a stressful ante mortemtreatment and Mg&Trp supplementation led to carcasses with high incidence of severeskin lesions. Different meat quality results were found when considering all pigs orconsidering only those with adequate supplement intake. In this later case, Trp increased pH45 (6.15) vs Control diet (5.96) in the Longissimus thoracis (LT) muscle (P<0.05) and pH at 24h (Trp: 5.59 vs C: 5.47) led to a higher incidence of dark, firm and dry (DFD) traits in SM muscle (P<0.05). Genotype affected negatively all the meat quality traits. Seventy-five percent of LT and 60.0% of the SM muscles from nn pigs wereclassified as pale, soft and exudative (PSE), while none of the NN pigs showed these traits (P<0.0001). No significant differences were found between genotypes on the incidence of DFD meat. Due to the negative effects observed in the Mg&Trp group in feed intake and carcass quality, the utilization of a mixture of magnesium sulphate and tryptophan is not recommended

Effect of supplementation with MgCO3 and L-tryptophan on the welfare and on the carcass and meat quality of two halothane pig genotypes (NN and nn)

Sixty-one animals with different Halothane genes (homozygous halothane positive, n=34; and homozygous halothane negative, n=27) were fed with three diets (controlgroup, with no supplement; magnesium (Mg) group with 1.28g MgCO3/kg and tryptophan (Trp) group with 5g L-Trp/kg) during the last 5 days before slaughter. Animals were submitted to minimal stress ante mortem conditions. Pig behaviour was recorded at the experimental farm, raceway to the CO2 stunning system and during the stunning period. Corneal reflexes were recorded after stunning as well. There were no differences in feed intake among diets (p>0.05) during the 5 days of treatment. Thehalothane positive (nn) group had lower intake than the halothane negative (NN) group(p<0.01). The behaviour of the pigs in the raceway did not differ (p>0.05) among treatments or halothane genotype. A significant (p<0.001) interaction diet*halothane was found in the time to appear the first retreat attempt during the exposure to the CO2 system. In the nn group, the time of performing the first retreat attempt was later in the Mg (p<0.05) than the Control group. Moreover, in the Mg group, the nn had a later (p<0.05) first retreat attempt than the NN. Thus, Mg supplementation could have a positive effect on welfare of nn pigs. The nn had a lower proportion of animals thatshowed corneal reflexes after stunning than NN, indicating a higher effectiveness of thestunning method in nn pigs. Neither Mg nor Trp affected carcass quality and meat quality parameters, although significant differences were found between genotypes

Zonation patterns of benthic communities in an upwelling area from de western Mediterranean (La Herradura, Alboran Sea)

Species composition and distribution of marine benthic communities from La Herradura (Alboran Sea, western Mediterranean) are described to characterise its rocky and sedimentary bottoms bionomically. Rocky bottoms were studied by means of several underwater transects and soft bottoms with fixed stations along a bathymetric gradient. The study of the floristic and faunistic composition of the rocky benthic communities highlights depth as the main axis of variation. Factorial Correspondence Analysis segregates deep-water communities below 25 m depth (circalittoral communities) from shallower communities (axis I), and communities thriving between 5 and 25 m depth (lower infralittoral communities) from communities thriving close to the surface (shallow infralittoral communities) (axis II). The study of the sedimentary bottoms also suggests that depth, together with physical sedimentary properties, is the main axis of variation in species distribution. Floristic and faunistic records show the particular composition of La Herradura benthic communities, compared to Mediterranean and Atlantic ones. Mixing of Mediterranean and Atlantic waters, together with deep water upwelling episodes typical of this area, probably determine the peculiar composition of the benthic communities

Combining genetic and demographic data for the conservation of a Mediterranean habitat-forming species

The integration of ecological and evolutionary data is highly valuable for conservation planning. However, it has been rarely used in the marine realm, where the adequate design of marine protected areas (MPAs) is urgently needed. Here, we examined the interacting processes underlying the patterns of genetic structure and demographic strucuture of a highly vulnerable Mediterranean habitat-forming species (i.e. Paramuricea clavata (Risso, 1826)), with particular emphasis on the processes of contemporary dispersal, genetic drift, and colonization of a new population. Isolation by distance and genetic discontinuities were found, and three genetic clusters were detected; each submitted to variations in the relative impact of drift and gene flow. No founder effect was found in the new population. The interplay of ecology and evolution revealed that drift is strongly impacting the smallest, most isolated populations, where partial mortality of individuals was highest. Moreover, the eco-evolutionary analyses entailed important conservation implications for P. clavata. Our study supports the inclusion of habitat-forming organisms in the design of MPAs and highlights the need to account for genetic drift in the development of MPAs. Moreover, it reinforces the importance of integrating genetic and demographic data in marine conservation.

Deep-water macroalgal-dominated coastal detritic assemblages on the continental shelf off Mallorca and Menorca (Balearic Islands, Western Mediterranean)

We present a quantitative physiognomic characterization of major macroalgal-dominated assemblages on coastal detritic bottoms of the continental shelf off Mallorca and Menorca (Balearic Islands, Western Mediterranean). In late spring of 2007 and 2008, 29 samples were collected by bottom trawling at depths between -52 and -93 m. These samples were then sorted and identified to their lowest taxonomic level. Statistical analyses distinguished six different assemblage types: shallower water environments (-52 to -65 m in depth) were characterized by Osmundaria volubilis and Phyllophora crispa meadows and two types of Peyssonnelia beds; two assemblage types, Laminaria rodriguezii beds and maërl beds, were only present in deep-water environments (-77 to -81 m); and an assemblage dominated by P. crispa and Halopteris filicina was found in both shallow and deep waters (-57 to -93 m). We assess the distribution of these six assemblage types through the studied area.

La credibilidad de los sistemas de evaluación formativa en docencia universitaria: un estudio de casos múltiple aplicado a la formación del profesorado

El objetivo de este artículo es estudiar diversos sistemas de evaluación formativa implantados en asignaturas de grado y máster adscritas a facultades de formación del profesorado. Para lograr este propósito, se lleva a cabo un plan de trabajo que adopta el formato de un estudio de casos múltiple. En cada uno de estos casos, los informadores son, por un lado, el profesorado responsable de la asignatura y, por otro, los estudiantes que han realizado las actividades de enseñanza y aprendizaje y que incluso han participado en su evaluación y calificación. Se han utilizado diferentes instrumentos de carácter cualitativo y cuantitativo con la intención de identificar las características principales de los sistemas de evaluación formativa implantados y de constatar los indicadores que permitirán establecer en qué grado los sistemas de evaluación formativa y participativa estudiados son pertinentes y aportan resultados creíbles. Los resultados indican que la credibilidad de estos sistemas de evaluación, además de las calificaciones, también depende de otros indicadores como la calidad del feedback proporcionado por el agente evaluador (docente o estudiante) durante la resolución de las actividades de evaluación, el empoderamiento y la capacidad de estos sistemas para contribuir al desarrollo profesional de los estudiantes. La principal conclusión que se desprende de este estudio se refiere al hecho de que las calificaciones académicas no pueden ser consideradas como el único factor a tener en cuenta para valorar la conveniencia de la evaluación formativa y participativa en docencia universitaria. En este sentido, el principal indicador de la credibilidad de un sistema de evaluación es su capacidad para aportar evidencias del fomento y la adquisición de aprendizajes profundos y competenciales.

Rescatando a Baiter: a propósito de la origo de Marco Celio Rufo (CIC. CAEL. 5)

El objetivo del texto es recuperar la intuición de Johan Georg Baiter (1801-­‐‑1877) que propuso Tusculum (Lacio, Italia) como patria de origen de Marco Celio Rufo enmendando una corruptela en la edición orelliana del Pro Caelio ciceroniano. Esta conjetura, desestimada en todas las ediciones posteriores del texto, ha sido recientemente confirmada gracias al hallazgo de un epígrafe que documenta por vez primera en la ciudad lacial un magistrado M. Caelius de época tardorepublicana.
