Se trata de un estudio sobre el contenido de las canciones de palmas que las ni??as suelen cantar entre los 5 y los 10 a??os. Se busca su origen y el papel que juegan en el contexto sociocultural. En cada ??poca hist??rica han variado los contenidos como reflejo de la evoluci??n social, pero en general se trata de temas poco adecuados a esta edad como temas de discriminaci??n de g??nero, robos o asesinatos. Se hace un an??lisis de este juego narrativo, de los roles de g??nero y de c??mo se transmite de unos ni??os a otros, sin que el adulto vea m??s que un juego de ni??os.

Intra-urban inequalities in mortality have been infrequently analysed in European contexts. The aim of the present study was to analyse patterns of cancer mortality and their relationship with socioeconomic deprivation in small areas in 11 Spanish cities

Sixty-nine entire male pigs with different halothane genotype (homozygous halothane positive – 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 5 days 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 ante mortem period, 15.2% of pigs included in the experiment died, and this percentage decreased to 8.7% in those pigs with a feed intake > 2kg/day, all of them from the stress-sensitive pigs (nn). In general, no differences were observed in the behaviour of pigs along the corridor leading to the stunning system and inside the CO2 stunning system. During the stunning procedure, Trp diet showed shorter periods of muscular excitation than control and Mg&Trp diets. The combination of a stressful ante mortem treatment and Mg&Trp supplementation led to carcasses with high incidence of severe skin lesions. Different meat quality results were found when considering all pigs or considering 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 were classified 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

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. The halothane 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 that showed corneal reflexes after stunning than NN, indicating a higher effectiveness of the stunning method in nn pigs. Neither Mg nor Trp affected carcass quality and meat quality parameters, although significant differences were found between genotypes

Una mirada a l'estudiant universitari: què necessitarà saber i saber fer quan s'incorpori al mercat laboral? Aquesta ponència exposa la recerca que s'està duent a terme dins un projecte REDICE, finançat per l'ICE de la UB. Es mostra el context en què s'emmarca, els seus objectius i metodologia, i els resultats esperats. La recerca analitza una de les arrels de la manca de rendiment laboral dels treballadors, remuntant-se a un dels seus orígens: la formació que han rebut, en particular aquells que han seguit una trajectòria universitària. Segons el plantejament del projecte, una planificació de la docència més centrada en l'estudiant, des de la perspectiva de formar-lo de manera integral, pot contribuir de forma significativa a incrementar la seva futura productivitat laboral

Hi ha dos tipus d'interrogants que ens plantegem en aquesta presentació: En primer lloc exposem un seguit de realitats que afecten directament al disseny de la nostra assignatura: els professors assumim habilitats apreses en tècniques de treball dels nostres estudiants: treball en equip, presentacions, debats.... Els uns i els altres entenem el mateix, del què i el com s'ha de treballar? Ho comprovarem. Alhora, ens preguntarem si els estudiants assumim habilitats tecnològiques del professorat? Moodle, wikis, Twitter, xats..... tots entenem el mateix i els fem servir de la mateixa manera? Fixem-nos en les dues perspectives, la del professor i la de l'estudiant, tant referent a dinamiques com a recursos, i ens adonarem que cal tenir en compte tant la una com l'altra. Aquestes reflexions afecten al plantejament de l'assignatura i ens deixen clar que hi ha molta feina a fer per trobar les respostes (conèixer als estudiants que tenim a les aules, explicar convenientment el que esperem dels estudiants, com plantegem l'assignatura i com l'avaluarem... ) No ens referim exclusivament a tenir un pla docent detallat a la maxima expresió, sinó que ens referim a reconèixer el com, el quan i el que expliquem als nostres estudiants, de manera que les regles del joc quedin enteses de la mateixa manera per una part i per l'altra. A partir d'aquí, i com a segon interrogant, ens plantejarem l'estructura que combina la part presencial i la part no presencial de l'assignatura: Quines són les activitats de les que puc treure més rendiment en la part presencial de l'assignatura i quines en la part no presencial? Quant temps i com calcular-lo, cal invertir en les activitats, tant per part dels estudiants com per part del professorat? Com podem avaluar una activitat que ha estat realitzada en part presencial i en part no presencial
