Key competences in the new ventures: a model for evaluating

This research studies from an internal view based on the Competency-Based Perspective (CBP), key organizational competencies developed for small new business. CBP is chosen in an attempt to explain the differences characterizing the closed companies from the consolidated ones. The main contribution of this paper is the definition of a set of key organizational competencies for new ventures from services and low technology based sectors. Using the classification proposed by [1] and a review of the entrepreneurship literature, the main competencies were defined and classified as: managerial, input-based, transformation-based, and output-based competencies. The proposed model for evaluating new ventures organizational competence is tested by means of Structural Equation

Molecular characterisation of Sporothrix schenckii isolates from humans and cats involved in the sporotrichosis epidemic in Rio de Janeiro, Brazil

An epidemic of sporotrichosis, a subcutaneous mycosis caused by the fungus Sporothrix schenckii, is ongoing in Rio de Janeiro, Brazil, in which cases of human infection are related to exposure to cats. In an attempt to demonstrate the zoonotic character of this epidemic using molecular methodology, we characterised by DNA-based typing methods 19 human and 25 animal S. schenckii isolates from the epidemic, as well as two control strains. To analyse the isolates, the random amplified polymorphic DNA (RAPD) technique was performed using three different primers, together with DNA fingerprinting using the minisatellite derived from the wild-type phage M13 core-sequence. The analyses generated amplicons with considerable polymorphism. Although isolates exhibited high levels of genetic relatedness, they could be clustered into 5-10 genotypes. The RAPD profiles of epidemic S. schenckii isolates could be distinguished from that of the United States isolate, displaying 20% similarity to each primer and 60% when amplified with the M13 primer. DNA fingerprinting of S. schenckii isolated from the nails (42.8%) and the oral cavities (66%) of cats were identical to related human samples, suggesting that there is a common infection source for animals and humans in this epidemic. It is clear that cats act as a vehicle for dissemination of S. schenckii.

Vector density and the control of kala-azar in Bihar, India

Bihar, India has been in the grip of kala-azar for many years. Its rampant and severe spread has made life miserable in most parts of the state. Such conditions require a comprehensive understanding of this affliction. The numbers coming out of the districts prone to the disease in the north and south Ganges have provided us with several startling revelations, as there are striking uniformities on both sides, including similar vegetation, water storage facilities, house construction and little change in risk factors. The northern areas have been regularly sprayed with DDT since 1977, but eradication of the disease appears to be a distant dream. In 2007 alone, there were as many as 37,738 cases in that region. In contrast, the southern districts of Patna and Nalanda have never had the disease in its epidemic form and endemic disease has been present in only some pockets of the two districts. In those cases, two rounds of spraying with DDT had very positive results, with successful control and no new established foci. In addition, an eleven-year longitudinal study of the man hour density and house index for the vector Phlebotomus argentipes demonstrated that they were quite high in Patna and Nalanda and quite low in north Bihar. Given these facts, an attempt has been made to unravel the role of P. argentipes saliva (salivary gland) in the epidemiology of kala-azar. It was determined that patchy DDT spraying should be avoided for effective control of kala-azar.

Medi ambient i equitat : la perspectiva del gènere

L'article transcriu el que va ser una sessió del seminari 'Medi ambient, trajectòries de vida i interdisciplinarietat'. Nous reptes en geografia del gènere, inserit en el programa de tercer cicle en geografia humana de la UAB, corresponent al curs 1991-1992. S'hi presenta una àmplia panoràmica d'un enfocament de gènere per a l'anàlisi dels problemes del medi ambient; això es concreta, d'una banda, en la presentació d'un esbós de la situació de les dones en relació el medi ambient; diferenciant, segons les seves especificitats d'índole diversa, entre països desenvolupats i subdesenvolupats, i, d'altra banda, en un intent de sistematització de les línies de recerca i acció que són impulsades per les estudioses i les activistes en matèria de medi ambient i gènere

El medi està androcentrat. Qui el desandrocentritzarà?... Experiència femenina, coneixement ecològic i canvi cultural

The article is the result of an attempt to define universal categories which permit a nonandrocentric conceptualization of the natural environment, in which femenine experience in environmental topics is unveiled and emphatized as a collective heritage. The theoretic content concentrates on defining and outlining the characteristics of two basic concepts: the femenine model of conscience and environmental actionr and ccwomen's ecologismn. The potential of both concepts for structuring research in genderlenvironment relations is demostrated. Finally, the article offers reasoned criticism of the androcentric nature of the guide-lines which predominate in environmental management and proposes, as the basis of an alternative model, the recognition of the legitimacy and authority of feminine experience in environmental affairs

Assaig de definició de l’àrea urbana de Girona

This article is an essay aiming at the definition of the urban district of Girona, having as a base the analysis of the intensities and directional tendencies of labour mobility fluxes in it. Several cathegories will be signaled inside this area which wil enable us to differenciate a number of crowns of municipalities according to their respective links with Girona town. A reflection set forth by Francesco Indovina on the concept of diffused town will be the first step in the attempt to typify this area. Thus, the existence of a diffused city core of which would be Girona town will be argued, an issue this one which is to be analysed in future studies

Innate immunity and regulatory T-cells in human Chagas disease: what must be understood?

There is a general consensus that during chronic Trypanosoma cruzi infection, the host immune system induces complex processes to ensure the control of parasite growth while preserving the potential to mount and maintain a life-long controlled humoral and cellular immune response against the invading pathogen. This review summarises evidence in an attempt to elucidate "what must be understood" to further clarify the role of innate immunity in the development/maintenance of clinical Chagas disease and the impact of etiological treatment on host immunity, highlighting the contributions of the innate immunity and regulatory T (Treg) cells. Recently, increasing focus on innate immunity suggest that chronic T. cruzi infection may cause morbidity when innate effector functions, or the down-regulation of adaptive regulatory mechanisms are lacking. In this context, stable asymptomatic host-parasite interactions seem to be influenced by the effector/regulatory balance with the participation of macrophages, natural killer (NK) and CD8+ T cells in parallel with the establishment of regulatory mechanisms mediated by NKT and Treg cells. Moreover, a balanced innate immune activation state, apart from Treg cells, may play a role in controlling the adverse events triggered by the massive antigen release induced by trypanosomicidal agents during Chagas disease etiological treatment.

Regulatory elements involved in the post-transcriptional control of stage-specific gene expression in Trypanosoma cruzi: a review

Trypanosoma cruzi, a protozoan parasite that causes Chagas disease, exhibits unique mechanisms for gene expression such as constitutive polycistronic transcription of protein-coding genes, RNA editing and trans-splicing. In the absence of mechanism controlling transcription initiation, organized subsets of T. cruzi genes must be post-transcriptionally co-regulated in response to extracellular signals. The mechanisms that regulate stage-specific gene expression in this parasite have become much clearer through sequencing its whole genome as well as performing various proteomic and microarray analyses, which have demonstrated that at least half of the T. cruzi genes are differentially regulated during its life cycle. In this review, we attempt to highlight the recent advances in characterising cis and trans-acting elements in the T. cruzi genome that are involved in its post-transcriptional regulatory machinery.

Opioids and the skin--where do we stand?

The common ectodermal origin of the skin and nervous systems can be expected to predict likely interactions in the adult. Over the last couple of decades much progress has been made to elucidate the nature of these interactions, which provide multidirectional controls between the centrally located brain and the peripherally located skin and immune system. The opioid system is an excellent example of such an interaction and there is growing evidence that opioid receptors (OR) and their endogenous opioid agonists are functional in different skin structures, including peripheral nerve fibres, keratinocytes, melanocytes, hair follicles and immune cells. Greater knowledge of these skin-associated opioid interactions will be important for the treatment of chronic and acute pain and pruritus. Topical treatment of the skin with opioid ligands is particularly attractive as they are active with few side effects, especially if they cannot cross the blood-brain barrier. Moreover, cutaneous activation of the opioid system (e.g. by peripheral nerves, cutaneous and immune cells, especially in inflamed and damaged skin) can influence cell differentiation and apoptosis, and thus may be important for the repair of damaged skin. While many of the pieces of this intriguing puzzle remain to be found, we attempt in this review to weave a thread around available data to discuss how the peripheral opioid system may impact on different key players in skin physiology and pathology.

Toward Protein Biomarkers for Allergy: CD4+ T Cell Proteomics in Allergic and Nonallergic Subjects Sampled in and out of Pollen Season.

Allergy is an immunological disorder of the upper airways, lung, skin, and the gut with a growing prevalence over the last decades in Western countries. Atopy, the genetic predisposition for allergy, is strongly dependent on familial inheritance and environmental factors. These observations call for predictive markers of progression from atopy to allergy, a prerequisite to any active intervention in neonates and children (prophylactic interventions/primary prevention) or in adults (immunomodulatory interventions/secondary prevention). In an attempt to identify early biomarkers of the "atopic march" using minimally invasive sampling, CD4+ T cells from 20 adult volunteers (10 healthy and 10 with respiratory allergies) were isolated and quantitatively analyzed and their proteomes were compared in and out of pollen season (± antigen exposure). The proteome study based on high-resolution 2D gel electrophoresis revealed three candidate protein markers that distinguish the CD4+ T cell proteomes of normal from allergic individuals when sampled out of pollen season, namely Talin 1, Nipsnap homologue 3A, and Glutamate-cysteine ligase regulatory protein. Three proteins were found differentially expressed between the CD4+ T cell proteomes of normal and allergic subjects when sampled during pollen season: carbonyl reductase, glutathione S-transferase ω 1, and 2,4-dienoyl-CoA reductase. The results were partly validated by Western blotting.

Recepción, clasificación según escala Manchester y atención sanitaria inicial al paciente que acude a un Dispositivo de Cuidados Críticos y Urgencias (DCCU) con motivo de consulta “Diabetes”: Posibilidad de intervención finalista de la enfermera en la consulta de triage (Triage Avanzado) ante la hipoglucemia. Colaboración multidisciplinar y criterios de derivación

The Andalusian Public Health System (SSPA) is considering the last time an attempt urgent process management through triage consultation, both hospital and primary care environment and tables situations in which the nurse responsible for these consultations can carry out a final statement of which only she is directly responsible through their independent intervention and referral (Triage Advanced). Pose, at once and consistently to the idea of teamwork, where they can be the limits to that intervention finalist and the circuits to follow. This paper proposes a definition line of one of those situations through triage concepts universally tested, and takes full advantage of advanced practice profile offered by nurses Device Critical Care (DCCU) of the SSPA and any the emerging legal and regulatory framework in terms of standardized collaborative prescription, us know legitimate receivers. This work stems from the vision of professionals and our contribution to that line of institutional work that must be consensus.

Utilité et limites du dosage de l'antigène carcinoembryonnaire (CEA) dans la surveillance postopératoire de malades atteints de carcinomes du côlon et du rectu

An attempt is made to define the usefulness and limitations of carcinoembryonic antigen (CEA) radioimmunoassay for evaluation of tumor resection and detection of tumor relapse in patients with large-bowel carcinoma. In 45 patients for whom complete tumor resection was reported, all but 5 showed a drop in CEA to normal values after surgery. The 5 patients whose CEA did not fall to below 5 ng/ml showed a subsequent rise in CEA level and later were all found to have a tumor relapse. The results indicate that an incomplete drop in circulating CEA level one month after surgery is a bad prognostic sign. Twenty-two of these patients were followed up by repeated CEA radioimmunoassay for several months after surgery; 8 showed a progressive increase in CEA levels preceding clinical diagnosis of tumor relapse by 2-10 months. The clinical history of these 8 patients is briefly described. The results demonstrate that relapses of colon and rectum carcinoma can be detected by increased CEA levels months before the appearance of any clinical evidence.

La recepció de la narrativa catalana contemporània traduïda a l'alemany: 1975-2009

Entre l'abril de 2007 i l'abril del 2011 vaig gaudir d'un ajut FI al Departament de Traducció i Ciencies del Llenguatge de la Universitat Pompeu Fabra. Gràcies a aquest ajut i en el marc del programa de doctorat en Comunicació Multilingüe vaig poder dur a terme un projecte de recerca sobre la recepció de la narrativa catalana traduïda a l'alemany des de 1975 fins a l’actualitat. El primer resultat d'aquest projecte és el nou treball de recerca, llegit el novembre de 2010, en el qual intento fer un balanç de les obres de narrativa d'autors catalans publicades en alemany durant els darrers 30 anys: a partir del catàleg de totes les obres da narrativa catalana traduïdes en el període estudiat, he establert una tipologia per classificar els textos en generes i per comprovar quins autors i quines obres s'han traduït majoritàriament, per quins autors i per quins generes s'han interessat més els editors alemanys i fins a quin punt es pot considerar que aquestes traduccions representen d'una manera equilibrada narrativa catalana d'aquests anys. En el treball també he analitzat les característiques de les editorials on s'han publicat les obres traduïdes i he intentat avaluar la seva recepció, a partir de la traducció dels títols i els textos de presentació de les obres. Fet aquest primer balanç, ara estic preparant quatre articles que aprofundeixen en temes plantejats al treball de recerca i que junts han de formar la meva tesi doctoral, actualment en curs d'elaboració. A banda de la meva recerca personal, l'ajut FI també m'ha permès formar-me com a investigadora, amb la publicació d'articles, la docència al departament, la participació en congressos i, sobretot, la col•laboració amb el grup de recerca TRILCAT, d'estudis de traducció, recepció i literatura catalana.
