Cross-section data, disequilibrium situations and estimated coefficients: evidence from car ownership demand

The objective of this paper is to analyse to what extent the use of cross-section data will distort the estimated elasticities for car ownership demand when the observed variables do not correspond to a state equilibrium for some individuals in the sample. Our proposal consists of approximating the equilibrium values of the observed variables by constructing a pseudo-panel data set which entails averaging individuals observed at different points of time into cohorts. The results show that individual and aggregate data lead to almost the same value for income elasticity, whereas with respect to working adult elasticity the similarity is less pronounced.

Taxonomic study and redescription of Culex (Melanoconion) theobaldi (Lutz, 1904) (Diptera: Culicidae)

Based on type examination, Culex (Melanoconion) theobaldi (Lutz, 1904) is redescribed. The species Cx. (Mel.) chrysonotum Dyar & Knab, 1908, was put back as synonym of theobaldi. Besides, examination of Cx. (Mel.) chrysothorax (Newstead & Thomas, 1910) type, leads to retiring as synonym of theobaldi and considered it as "species inquirenda".

Prenatal manifestation and management of a mother and child affected by spondyloperipheral dysplasia with a C-propeptide mutation in COL2A1: case report.

It is not unusual for patients with "rare" conditions, such as skeletal dysplasias, to remain undiagnosed until adulthood. In such cases, a pregnancy may unexpectedly reveal hidden problems and special needs. A 28 year old primigravida was referred to us at 17 weeks for counselling with an undiagnosed skeletal dysplasia with specific skeletal anomalies suggesting the collagen 2 disorder, spondyloperipheral dysplasia (SPD; MIM 156550).She was counselled about the probability of dominant inheritance and was offered a prenatal diagnosis by sonography. US examination at 17, 18 and 20 weeks revealed fetal macrocephaly, a narrow thorax, and shortening and bowing of long bones. The parents elected to continue the pregnancy. At birth the baby showed severe respiratory distress for four weeks which then resolved. Mutation analysis of both mother and child revealed a hitherto undescribed heterozygous nonsense mutation in the C-propeptide coding region of COL2A1 confirming the diagnosis of SPD while reinforcing the genotype-phenotype correlations between C-propeptide COL2A1 mutations and the SPD-Torrance spectrum. This case demonstrates the importance of a correct diagnosis even in adulthood, enabling individuals affected by rare conditions to be made aware about recurrence and pregnancy-associated risks, and potential complications in the newborn.

Comparative study and identification of potent eukaryotic transcriptional repressors in gene switch systems.

In mammalian cells, proper gene regulation is achieved by the complex interplay of transcription factors that activate or repress gene expression by binding to the regulatory regions of target promoters. While transcriptional activators have been extensively characterised and classified into functional groups, relatively little is known about the comparative strength and cell type-specificity of transcriptional repressors. Here, we have compared the ability of a series of eukaryotic repression domains to silence basal and activated transcription. A series of the most potent repression domains was further tested in the context of a gene therapy gene-switch system in various cell types. The results indicate that the analysed repression domains exert varying silencing activities in different promoter contexts. Furthermore, their potential for gene silencing varies also depending on the cellular context. When multimerised within one chimeric repressor protein, particular combinations of repressor domains were found to display synergistic repressing effects and efficient repression in a panel of cell lines. This approach thus allowed the identification of transcriptional repressors that are both potent and versatile in terms of cellular specificity as a basis for gene switch systems.

Intérêt des faibles doses de rt-PA dans les syndromes inflammatoires et hémorragiques du segment antérieur: étude clinique et revue de la littérature [Treatment of anterior segment fibrinous reactions and hemorrhage with intracameral low dose rt-PA: clinical study and review of the literature].

PURPOSE: to evaluate the efficacy and the safety of low dose intraocular tissue plasminogen activator (rt-PA) in the treatment of traumatic hyphema and postoperative fibrinous membrane. METHODS: Six microg to 10 microg of rt-PA was injected into the anterior chamber to treat severe fibrinous postoperative membranes and total traumatic hyphemae. RESULTS: Thirteen eyes of 13 patients were treated. Four cases of traumatic hyphema and 9 cases of fibrinous membranes were included. Complete fibrinolysis within 24 hours was observed in 4 cases (30.8%). A partial success was noted in 7 eyes (53.8%). No beneficial effect was observed in two cases of traumatic hyphema associated with intravitreal hemorrhage after penetrating trauma. No side effect attributable to rt-PA occurred. CONCLUSION: Low dose intraocular rt-PA appears to be safe and effective in the treatment of postoperative fibrinous membrane and endocular hemorrhage limited to the anterior chamber.

La visite médicale en pratique hospitalière: entre soins et apprentissage [Conducting ward rounds: a balance between care and teaching].

Every day, hospital doctors spend time at conducting ward rounds. Rounds are a core clinical activity during which doctors interact with patients, synthetise a whole set of informations and make many decisions. In addition, rounds can become a crucial teaching moment, when a trainee gets supervised by an attending physician. However, litterature on the topic of rounds is scarce. This paper summarizes the results of the few key studies focusing on ward rounds. The results are presented in four sections, each one being dedicated to one of the round stakeholders: the trainee or resident, the trainer, the patient and the nurse. An emphasis is put on ward rounds involving both a trainee and a trainer, since such rounds always mean striking a balance between care and teaching.

Classificació dels projectes informàtics i les EDT's

Aquest projecte tracta de recopilar tots els conceptes, criteris i característiques que es poden aplicar a un projecte amb l'ànim de que els lliuraments de projectes siguin fidels i es corresponguin amb la pràctica i realitat del servei o producte que es desitgi desenvolupar. Per garantir l'èxit ens centrarem en el disseny, planificació i visualització dels projectes fent ús de les WBS (Work Breakdown Structure) o EDT (Estructura del treball). Aquesta tècnica permet a l'equip de projecte exposar esquemàticament quin és el seu abast i socialitzar-les entre els diversos actors o persones involucrades de manera clara i esquematitzada.

L'escola a la societat xarxa : Internet a l'educació primària i secundària. Informe final de recerca (volum II)

Aquest projecte té la intenció d'identificar i analitzar els efectes de la introducció d'Internet a les escoles catalanes (educació primària i secundària). L'objectiu és posar de manifest la manera com s'utilitza la xarxa en aquest àmbit i en quina mesura contribueix a l'aparició, en els centres educatius, d'una nova cultura adaptada a les necessitats de la societat xarxa. Amb aquest propòsit, aquest projecte desplega les seves línies d'anàlisi per a fer atenció al procés d'incorporació d'Internet, principalment, en tres direccions: la pràctica pedagògica, les formes d'organització i gestió dels centres educatius i la seva vinculació amb la comunitat i el territori. Aquesta investigació ha estat desenvolupada pel grup de recerca ENS (Education and Network Society). Amb una perspectiva comparativa, el treball d'aquest grup vol contribuir, sobre la base de dades empíriques, a interpretar la transformació de l'àmbit educatiu no universitari en els paràmetres que estableix, avui dia, la nostra societat.
