Fonaments d'un programa informàtic de suport psicològic i superació personal : dels llibres d'autoajuda al software d'autoajuda

Aquest treball descriu els principis de disseny i els components essencials d'un hipotètic programa informàtic que té per finalitat facilitar el procés d'autoajuda i que també pot ser utilitzat com a eina de desenvolupament personal i motivació. Prèviament, l'autor fa una revisió dels mètodes existents, des de l'èxit dels llibres d'autoajuda del segle XX fins al'expansió de la interactivitat impulsada pel desenvolupament de les tecnologiesinformàtiques. A través d'aquest recorregut es constata la pobre implantació de les novestecnologies com a instruments populars d'autoajuda i s'advoca per la creació i ús deprogrames informàtics flexibles i generalistes com a mitjà de suport psicològic.

Reproductive isolation between sympatric and allopatric Brazilian populations of Lutzomyia longipalpis s.l. (Diptera: Psychodidae)

Lutzomyia longipalpis s.l., the main vector of Leishmania chagasi in Latin America, is a species complex although the exact number of siblings is yet unknown. In Brazil, the siblings differ in male copulatory courtship songs and pheromones that most certainly act as pre-zygotic reproductive barriers. Here we analysed the reproductive isolation between three allopatric and two sympatric populations of Lu. longipalpis s.l. from Brazil. The results indicate a strong copulatory and pre-mating isolation between the three allopatric populations. In addition, the results also indicate a stronger pre-mating isolation between the two sympatric siblings than between the three allopatric ones, suggesting a role for reinforcement in the speciation of the Lu. longipalpis s.l. complex.

Paternity and health services. Qualitative research on men's experiences during pregnancy, delivery and postpartum of theirs partners

Background: Little research has been carried out with regards to the inclusion of men during the birth process. The objective of this paper involves exploring the needs and expectations of the health services manifested by a group of fathers as a result of their experience during the birth process. Methods: Qualitative research was carried out in Granada in 2004 via individual interviews with fathers who showed shared responsibility in the upbringing. The profile is: employment, medium-high educational level, one or more child: 0-6 months of age. The transcript was subsequently submitted to hermeneutic analysis. Results: Some semantic constructs are: 1) Health Services do not concede the women as protagonists, 2) Birth process is depending on the body. Fathers can only support and fight for the relevance of men, 3) Men seem like “invisible”, 4) Health services inhibit their participation, and 5) have dealings with fathers according to their gender roles. The participants address the relationship between expectations of care during the birth process and unsatisfied demands, and the manner in which they employ the obstacles encountered within health services that inhibit their participation as arguments that confirm their separation from the process. Conclusions: This paper draws attention to the limited scope of the provision of healthcare during the birth process in terms of protagonism afforded to fathers. Indeed, despite their requisitory discourse, the interviewees manifest contradictory attitudes in the face of changes that require them to make commitments. We identify elements that could be improved to adapt services to the needs of fathers and vice versa.

Deficiencia nutricional de yodo en gestantes pertenecientes al distrito sanitario Sierra de Huelva-Andévalo, sur de España

Background. Iodine is an essential trace element implicated in synthesis of thyroid hormones. Iodine requirements vary throughout life. Yhis iodine requirement is increased during pregnancy and breastfeeding. In a previous study carried out by our group in 2008, we detected an iodine-deficient area in the province of Huelva, specially in dictrict Sierra de Huelva-Andévalo by means of neonatal TSH determinations. Objective. To reinforce the iodine supplementation campaign and its impact on their newborns in order to assess nutrition iodine status in 'pregnant women using questionnaire and ioduria determination. Material and methods. This study has been jointly carried out by Congenital Hypothiroidism Unit of the Clinical Biochemistry Department of the Virgen Macarena University Hosplital (Seville) and the Gynecology and Clinical Analysis Unit of the Río Tinto Hospital (Huelva) during two years. We studied 313 pregnant women. All of them filled out a personal questionnaire to know the iodine nutritional status in their area. Ioduria was determined by high-resolution liquid chromatography. Data from pregnant and results of the studied variables were analyzed with SPSS v.13.0. Conclusions. Pregnant women from the sanitary district Sierra de Huelva-Andévalo present a median for ioduria which corresponds to an insufficient iodine intake according to the WHO classification. The questionnaire suggest that this iodine deficiency is consequence of an insufficient iodine intake and a low adherence to the treatment.

Analysis of Pleistocene paleodrainage evolution in the Po Basin (Italy) by multivariate statistical techniques

In order to obtain a high-resolution Pleistocene stratigraphy, eleven continuouslycored boreholes, 100 to 220m deep were drilled in the northern part of the PoPlain by Regione Lombardia in the last five years. Quantitative provenanceanalysis (QPA, Weltje and von Eynatten, 2004) of Pleistocene sands was carriedout by using multivariate statistical analysis (principal component analysis, PCA,and similarity analysis) on an integrated data set, including high-resolution bulkpetrography and heavy-mineral analyses on Pleistocene sands and of 250 majorand minor modern rivers draining the southern flank of the Alps from West toEast (Garzanti et al, 2004; 2006). Prior to the onset of major Alpine glaciations,metamorphic and quartzofeldspathic detritus from the Western and Central Alpswas carried from the axial belt to the Po basin longitudinally parallel to theSouthAlpine belt by a trunk river (Vezzoli and Garzanti, 2008). This scenariorapidly changed during the marine isotope stage 22 (0.87 Ma), with the onset ofthe first major Pleistocene glaciation in the Alps (Muttoni et al, 2003). PCA andsimilarity analysis from core samples show that the longitudinal trunk river at thistime was shifted southward by the rapid southward and westward progradation oftransverse alluvial river systems fed from the Central and Southern Alps.Sediments were transported southward by braided river systems as well as glacialsediments transported by Alpine valley glaciers invaded the alluvial plain.Kew words: Detrital modes; Modern sands; Provenance; Principal ComponentsAnalysis; Similarity, Canberra Distance; palaeodrainage

Robust regression in biological assay: application to the evaluation of alternative experimental techniques.

Robust Huber type regression and testing of linear hypotheses are adapted to statistical analysis of parallel line and slope ratio assays. They are applied in the evaluation of results of several experiments carried out in order to compare and validate alternatives to animal experimentation based on embryo and cell cultures. Computational procedures necessary for the application of robust methods of analysis used the conversational statistical package ROBSYS. Special commands for the analysis of parallel line and slope ratio assays have been added to ROBSYS.

Use of unmodified starches and partial removal of serum to improve Granada medium stability

The use of 1% unmodified rice starch and 1% horse serum instead of 2% soluble starch and 5% serum in Granada medium is described. These components result in a medium of increased stability, preventing spoilage after a few days of storage at room temperature

Specimen storage in transport medium and detection of group B streptococci by culture

Recovery of group B streptococci (GBS) was assessed in 1,204 vaginorectal swabs stored in Amies transport medium at 4 or 21°C for 1 to 4 days either by direct inoculation onto Granada agar (GA) or by culture in blood agar (BA) and GA after a selective broth enrichment (SBE) step. Following storage at 4°C, GBS detection in GA was not affected after 72 h by either direct inoculation or SBE; however, GBS were not detected after SBE in the BA subculture in some samples after 48 h of storage and in GA after 96 h. After storage at 21°C, loss of GBS-positive results was significant after 48 h by direct inoculation in GA and after 96 h by SBE and BA subculture; some GBS-positive samples were not detected after 24 h of storage followed by SBE and BA subculture or after 48 h of storage followed by SBE and GA subculture. Storage of swabs in transport medium, even at 4°C, produced after 24 h an underestimation of the intensity of GBS colonization in most specimens. These data indicate that viability of GBS is not fully preserved by storage of vaginorectal swabs in Amies transport medium, mainly if they are not stored under refrigeration
