Sham nepotism as a result of intrinsic differences in brood viability in ants.

In animal societies, cooperation for the common wealth and latent conflicts due to the selfish interests of individuals are in delicate balance. In many ant species, colonies contain multiple breeders and workers interact with nestmates of varying degrees of relatedness. Therefore, workers could increase their inclusive fitness by preferentially caring for their closest relatives, yet evidence for nepotism in insect societies remains scarce and controversial. We experimentally demonstrate that workers of the ant Formica exsecta do not discriminate between highly related and unrelated brood, but that brood viability differs between queens. We further show that differences in brood viability are sufficient to explain a relatedness pattern that has previously been interpreted as evidence for nepotism. Hence, our findings support the view that nepotism remains elusive in social insects and emphasize the need for further controlled experiments.

The QCD Potential at O(1/m2): Complete spin-dependent and spin-independent result

Within an effective field theory framework, we obtain an expression, with O(1/m2) accuracy, for the energies of the gluonic excitations between heavy quarks, which holds beyond perturbation theory. For the singlet heavy-quarkantiquark energy, in particular, we also obtain an expression in terms of Wilson loops. This provides, twenty years after the seminal work of Eichten and Feinberg, the first complete expression for the heavy quarkonium potential up to O(1/m2) for pure gluodynamics. Several errors present in the previous literature (also in the work of Eichten and Feinberg) have been corrected. We also briefly discuss the power counting of NRQCD in the nonperturbative regime.

Stability of repeated student evaluations of teaching in the second preclinical year of a medical curriculum

RESUME L'étude de la médecine à la Faculté de l'Université de Lausanne est un cursus de six ans. Depuis la réforme générale du curriculum en octobre 1995, le programme de la deuxième année consacrée à l'étude de l'être humain sain a été transformé. L'enseignement intégré par système ou organe a été introduit en remplaçant l'enseignement par discipline. Parallèlement, un système d'évaluation de l'enseignement par les étudiants a été proposé. Il a été amélioré au fil des années et depuis l'année académique 1998-99, l'évaluation est devenue systémique et régulière. Notre étude présente et compare les résultats des évaluations de l'enseignement et des enseignants de neuf cours intégrés dispensés en deuxième année durant deux années académiques (1998-99 et 1999-2000). Une forte corrélation entre les résultats des deux années consécutives ainsi qu'une importante disparité des estimations à l'intérieure de chacune de deux années ont été observées. Ceci démontre un engagement sérieux des étudiants dans le processus d'évaluation, révèle la pertinence de leur analyse et leur bonne capacité de discernement. L'analyse de nos résultats montre que les évaluations effectuées par les étudiants peuvent constituer une source fiable d'informations et contribuer à l'amélioration du processus d'enseignement.

MORPHOLOGICAL AND MICROMORPHOLOGICAL CHANGES IN THE STRUCTURE OF A RHODIC HAPLUDOX AS A RESULT OF AGRICULTURAL MANAGEMENT

In evaluation of soil quality for agricultural use, soil structure is one of the most important properties, which is influenced not only by climate, biological activity, and management practices but also by mechanical and physico-chemical forces acting in the soil. The purpose of this study was to evaluate the influence of conventional agricultural management on the structure and microstructure of a Latossolo Vermelho distroférrico típico (Rhodic Hapludox) in an experimental area planted to maize. Soil morphology was described using the crop profile method by identifying the distinct structural volumes called Morphologically Homogeneous Units (MHUs). For comparison, we also described a profile in an adjacent area without agricultural use and under natural regrowth referred to as Memory. We took undisturbed samples from the main MHUs so as to form thin sections and blocks of soil for micromorphological and micromorphometrical analyses. Results from the application of the crop profile method showed the occurrence of the following structural types: loose (L), fragmented (F) and continuous (C) in both profiles analyzed. In the Memory soil profile, the fragmented structures were classified as Fptμ∆+tf and Fmt∆μ, whose micromorphology shows an enaulic-porphyric (porous) relative distribution with a great deal of biological activity as indicated by the presence of vughs and channels. Lower down, from 0.20 to 0.35 m, there was a continuous soil volume (sub-type C∆μ), with a subangular block microstructure and an enaulic-porphyric relative distribution, though in this case more compact and with aggregate coalescence and less biological activity. The micromorphometrical study of the soil of the Memory Plot showed the predominance of complex pores in NAM (15.03 %), Fmt∆μ (11.72 %), and Fptμ∆+tf (7.73 %), and rounded pores in C∆μ (8.21 %). In the soil under conventional agricultural management, we observed fragmented structures similar to the Memory Plot from 0.02 to 0.20 m, followed by a volume with a compact continuous structure (C∆μ), without visible porosity and with few roots. In the MHUs under conventional management, reduction in the packing pores (40 %) was observed, mainly in the continuous units (C). The microstructure had well-defined blocks, with the occurrence of planar pores and less evidence of biological activity. In conclusion, the morphological and micromorphological analyses of the soil profiles studied offered complementary information regarding soil structural quality, especially concerning the changes in pore types as result of mechanical stress undergone by the soil.

Laboratory Performance Evaluation of CIR-Emulsion and it Comparison Against CIR-Form Test Result from Phase II, Final Report TR-578 Phase III, December 2009

Currently, no standard mix design procedure is available for CIR-emulsion in Iowa. The CIR-foam mix design process developed during the previous phase is applied for CIR-emulsion mixtures with varying emulsified asphalt contents. Dynamic modulus test, dynamic creep test, static creep test and raveling test were conducted to evaluate the short- and long-term performance of CIR-emulsion mixtures at various testing temperatures and loading conditions. A potential benefit of this research is a better understanding of CIR-emulsion material properties in comparison with those of CIR-foam material that would allow for the selection of the most appropriate CIR technology and the type and amount of the optimum stabilization material. Dynamic modulus, flow number and flow time of CIR-emulsion mixtures using CSS-h were generally higher than those of HFMS-2p. Flow number and flow time of CIR-emulsion using RAP materials from Story County was higher than those from Clayton County. Flow number and flow time of CIR-emulsion with 0.5% emulsified asphalt was higher than CIR-emulsion with 1.0% or 1.5%. Raveling loss of CIR-emulsion with 1.5% emulsified was significantly less than those with 0.5% and 1.0%. Test results in terms of dynamic modulus, flow number, flow time and raveling loss of CIR-foam mixtures are generally better than those of CIR-emulsion mixtures. Given the limited RAP sources used for this study, it is recommended that the CIR-emulsion mix design procedure should be validated against several RAP sources and emulsion types.

Curriculum y doble lógica de inserción: lo universitario y las prácticas profesionales

La práctica intrauniversitaria y sus reglas autolegitimatorias, no tienen relación directa con las prácticas profesionales de quienes egresan de las universidades. De tal manera los planes de estudio pueden mantener sistemática disociación con las necesidaes profesionales, sin que ello implique disfunción alguna dentro de la actividad universitaria. Por cierto que la Universidad no tiene por qué responder mecánicamente a las demandas del mercado; pero sí debe asumir que la noción de crítica social debe resultar inmanente a las prácticas profesionales para las cuales se forma a los estudiantes. De lo contrario, se prepara a los mismos para el desempleo y la inadecuación laboral, o para un discurso que será abandonado en cuanto se inicie la actividad profesional.

Test result-based sampling: an efficient design for estimating the accuracy of patient safety indicators.

OBJECTIVE: Accuracy studies of Patient Safety Indicators (PSIs) are critical but limited by the large samples required due to low occurrence of most events. We tested a sampling design based on test results (verification-biased sampling [VBS]) that minimizes the number of subjects to be verified. METHODS: We considered 3 real PSIs, whose rates were calculated using 3 years of discharge data from a university hospital and a hypothetical screen of very rare events. Sample size estimates, based on the expected sensitivity and precision, were compared across 4 study designs: random and VBS, with and without constraints on the size of the population to be screened. RESULTS: Over sensitivities ranging from 0.3 to 0.7 and PSI prevalence levels ranging from 0.02 to 0.2, the optimal VBS strategy makes it possible to reduce sample size by up to 60% in comparison with simple random sampling. For PSI prevalence levels below 1%, the minimal sample size required was still over 5000. CONCLUSIONS: Verification-biased sampling permits substantial savings in the required sample size for PSI validation studies. However, sample sizes still need to be very large for many of the rarer PSIs.

A la recerca del lloc de la literatura infantil i juvenil en el curriculum escolar

La Reforma del sistema educatiu, innovadora en alguns aspectes, ha assignat algun espai a la Literatura Infantil i Juvenil (d'ara endavant, LIJ) en els dissenys curriculars. Pero ho ha fet d'una manera implícita, tacita, gairebé en complicitat amb el professor que vulgui recórrerhi en les seves activitats d'aula. Com que no es tracta d'un contingut, ni d'un objectiu d'aprenentatge en ella mateixa, la seva presencia esta diluida en les previsions curriculars. Pero hi éso. En aquestes pagines intentaré de presentar un conjunt de raons i referencies que avalin l'efectivitat de la utilització de la LIJ en l'ambit escolar, que supera la del seu ús com a mer recurs didactic.

Introducción a la farmacia galénica: un reto en primer año de farmacia

[spa] Este curso académico 2009-2010 se implanta el nuevo plan de estudios de Farmacia en la Universidad de Barcelona, diseñado según los planteamientos del EEES. Como consecuencia, y por primera vez en la historia de la Facultad de Farmacia de la UB, se imparte una asignatura troncal de cariz galénico en el primer año de la carrera. Esto constituye un nuevo reto para el Grupo de Innovación Docente de Tecnología Farmacéutica (GIDTF), dado que la asignatura Introducción a la Farmacia Galénica se ha de impartir a grandes grupos de estudiantes, al inicio de su carrera, mediante sesiones teóricas de 1,5 h. Excepcionalmente en este curso académico, la asignatura se imparte en el primer semestre y se repite en el segundo. En este trabajo se presenta el planteamiento metodológico presencial diseñado para esta asignatura, apoyado en estrategias no presenciales como foro de debate, recursos on-line, cuestionarios y tareas de autoevaluación a través de la plataforma Moodle del Campus Virtual de la UB, puesto que el equipo docente considera prioritario iniciar al estudiante en el uso de la misma en el primer año de carrera. Se han efectuado encuestas de satisfacción a los estudiantes que se han evaluado, así también como los resultados académicos obtenidos. En el análisis de los puntos fuertes y débiles de la metodología empleada, se han detectado evaluaciones positivas y también aspectos que podrían mejorarse, estableciendo las medidas correctoras adecuadas. En cuanto a los resultados académicos, han sido muy satisfactorios. [eng] This academic year 2009-2010, the new curriculum of Pharmacy according to the premises of the EHEA is started at the University of Barcelona. As a result, for the first time in the history of the Faculty of Pharmacy of UB, an obligatory galenic subject will be given during the first year of the career. This is a new challenge for Teaching Innovation Group of Pharmaceutical Technology (GIDTF), as the subject Introduction to Galenic Pharmacy is given by a team of teachers to large groups of students who began its career, through theoretical sessions of 1.5 h. The subject will be taught exceptionally this academic year in the first semester and repeated in the second. In this paper we present the methodological approach designed to face this subject, supported by virtual strategies as discussion forum, online resources, self-assessment test and work through the platform Moodle of the Virtual Campus UB, as the team considers it a priority to initiate the student in using it in the first year of pharmacy study. Were carried out satisfaction surveys to students and we have evaluated them, as well as academic performance. Through the analysis of the methodology, we detected positive evaluations and areas for improvement that have been used to establish appropriate corrective measures. Academic results have been very satisfactory.

FAM111A Mutations Result in Hypoparathyroidism and Impaired Skeletal Development.

Kenny-Caffey syndrome (KCS) and the similar but more severe osteocraniostenosis (OCS) are genetic conditions characterized by impaired skeletal development with small and dense bones, short stature, and primary hypoparathyroidism with hypocalcemia. We studied five individuals with KCS and five with OCS and found that all of them had heterozygous mutations in FAM111A. One mutation was identified in four unrelated individuals with KCS, and another one was identified in two unrelated individuals with OCS; all occurred de novo. Thus, OCS and KCS are allelic disorders of different severity. FAM111A codes for a 611 amino acid protein with homology to trypsin-like peptidases. Although FAM111A has been found to bind to the large T-antigen of SV40 and restrict viral replication, its native function is unknown. Molecular modeling of FAM111A shows that residues affected by KCS and OCS mutations do not map close to the active site but are clustered on a segment of the protein and are at, or close to, its outer surface, suggesting that the pathogenesis involves the interaction with as yet unidentified partner proteins rather than impaired catalysis. FAM111A appears to be crucial to a pathway that governs parathyroid hormone production, calcium homeostasis, and skeletal development and growth.

Enseignement prégradué de la médecine ambulatoire a la PMU: quelques repères [Pregraduate training in ambulatory care: a Swiss perspective].

The current lack of general practitioners in Switzerland is the result of health care policy which aimed in the past years to reduce the number of medical students and physicians in private practice. Furthermore, during the past decades, the Swiss Medical Schools emphasized on the transmission of medical care by specialists and neglected primary care medicine. The Faculty of medicine at the University of Lausanne recently decided to renew the curriculum. The Department of ambulatory care and community medicine (Policlinique Médicale Universitaire) of Lausanne is committed to the elaboration of this move. The biomedical model, essential to the acquisition of clinical competence, is still taught to the students. Nevertheless, from the beginning to the end of the curriculum, an emphasis is now put on the clinical skills and the clinical reasoning.
