Hematocrit (Hct) is one of the most critical issues associated with the bioanalytical methods used for dried blood spot (DBS) sample analysis. Because Hct determines the viscosity of blood, it may affect the spreading of blood onto the filter paper. Hence, accurate quantitative data can only be obtained if the size of the paper filter extracted contains a fixed blood volume. We describe for the first time a microfluidic-based sampling procedure to enable accurate blood volume collection on commercially available DBS cards. The system allows the collection of a controlled volume of blood (e.g., 5 or 10 μL) within several seconds. Reproducibility of the sampling volume was examined in vivo on capillary blood by quantifying caffeine and paraxanthine on 5 different extracted DBS spots at two different time points and in vitro with a test compound, Mavoglurant, on 10 different spots at two Hct levels. Entire spots were extracted. In addition, the accuracy and precision (n = 3) data for the Mavoglurant quantitation in blood with Hct levels between 26% and 62% were evaluated. The interspot precision data were below 9.0%, which was equivalent to that of a manually spotted volume with a pipet. No Hct effect was observed in the quantitative results obtained for Hct levels from 26% to 62%. These data indicate that our microfluidic-based sampling procedure is accurate and precise and that the analysis of Mavoglurant is not affected by the Hct values. This provides a simple procedure for DBS sampling with a fixed volume of capillary blood, which could eliminate the recurrent Hct issue linked to DBS sample analysis.

This article presents some of the results of a research project whose main objective was to analyse the relationship between resilience and school success of students of foreign origin at a time of special academic vulnerability: the transition from compulsory secondary education (ESO) to post-compulsory education (PO). By non-probabilistic-incidental sampling, the study was conducted in four schools of Barcelona and province, with 94 participants from 15 to 18 years old. This research of a longitudinal design had five phases combining strategies to collect qualitative and quantitative data. The results presented here are the result of the SV-RES adapted scale and two other self-produced toolsa center scale and a general questionnaire. The results obtained have confirmed the fulfilment of the hypothesis: immigrant students who manage to persevere in post-compulsory stages (Spanish Baccalaureate and/or Vocational Training) show higher levels of resilience.

The following paper introduces a new approach to the analysis of offensive game in football. Therefore, the main aim of this study was to create an instrument for collecting information for the analysis of offensive action and interactions game. The observation instrument that was used to accomplish the main objective of this work consists of a combination of format fields (FC) and systems of categories (SC). This methodology is a particular strategy of the scientific method that has as an objective to analyse the perceptible behaviour that occurs in habitual contexts, allowing them to be formally recorded and quantified and using an ad hoc instrument in order to obtain a behaviour systematic registration that, since they have been transformed in quantitative data with the necessary reliability and validity determined level, will allow analysis of the relations between these behaviours. The codifications undertaken to date in various games of football have shown that it serves the purposes for which it was developed, allowing more research into the offensive game methods in football.

L'étude présentée dans cet ouvrage offre pour la première fois en Suisse une perspective sociologique empirique et générale sur les organisations religieuses locales. Vu sous cet angle, le fait religieux se manifeste d'abord, comme le précisaient déjà Weber ou Durkheim, par l'existence de communautés de tailles et de profils divers, tant dans l'espace rural qu'urbain. En Suisse, 5'734 paroisses et groupes religieux ont pu être dénombrés en 2008. Ce recensement permet de souligner la prégnance institutionnelle des Eglises historiques, mais également l'émergence d'une plus forte pluralité religieuse, particulièrement en milieu urbain. La sociologie des organisations que propose cette étude permet de jeter un éclairage nouveau sur les effets de la sécularisation (baisse des membres et de la pratique) et de la pluralisation (diversification des confessions et traditions religieuses). L'analyse des différences et des similitudes organisationnelles selon les traditions religieuses fait apparaître un positionnement social des groupes en fonction de statuts acquis au cours de l'histoire. Les théories classiques - par exemple à pro- pos des relations entre statuts sociaux des membres et groupes d'appartenance, des types d'autorités religieuses ou encore des différences entre Eglise et Secte - sont revisitées, précisées ou reformulées grâce à des données quantitatives originales et représentatives du champ religieux suisse. -- The study presented in this book for the first time in Switzerland offers a broad empirical and sociological perspective on local religious organizations. From this perspective, religion appears first, as already observed by Weber and Durkheim, through communities regardless of their various profiles. In Switzerland, 5,734 parishes and religious groups have been identified by a national census in 2008. The book underlines the institutional salience of historical churches (Reformed and Roman Catholic) but also the emerging religious plurality, particularly in urban areas. This study sheds a new light upon the effects of secularization (lower limbs and practice) and pluralisation (diversification of religious denominations and traditions) in the organizational field. The analysis of differences and similarities between religious traditions shows a social positioning of the local groups according to the statutes acquired in history. The classical theories − e.g. about the relationship between social status of members and membership groups, types of religious authorities or differences between Church and Sect − are revisited, clarified or reformulated based on an original and representative quantitative data of the Swiss religious field.

AIMS: To explore, both among patients with diabetes and healthcare professionals, opinions on current diabetes care and the development of the "Regional Diabetes Program". METHODS: We employed qualitative methods (focus groups - FG) and used purposive sampling strategy to recruit patients with diabetes and healthcare professionals. We conducted one diabetic and one professional FG in each of the four health regions of the canton of Vaud/Switzerland. The eight FGs were audio-taped and transcribed verbatim. Thematic analysis was then undertaken. RESULTS: Results showed variability in the perception of the quality of diabetes care, pointed to insufficient information regarding diabetes, and lack of collaboration. Participants also evoked patients' difficulties for self-management, as well as professionals' and patients' financial concerns. Proposed solutions included reinforcing existing structures, developing self-management education, and focusing on comprehensive and coordinated care, communication and teamwork. Patients and professionals were in favour of a "Regional Diabetes Program" tailored to the actors' needs, and viewed it as a means to reinforce existing care delivery. CONCLUSIONS: Patients and professionals pointed out similar problems and solutions but explored them differently. Combined with coming quantitative data, these results should help to further develop, adapt and implement the "Regional Diabetes Program".

Tutkielman tarkoituksena on tutkia oppimisprosessin muodostumista ja toteutumista sekä prosessijohtamisen ja prosessien roolia SAP:in käyttöönottoprojektissa. Tutkielman case-organisaationa toimii Kespro Oy ja tutkimuskohteena on SAP:in käyttöönottoprojekti Kespron tukuissa. Tutkimus- ja tiedonkeruumenetelmänä käytetään kvantitatiivista kyselylomaketta. Tutkimuksessa saatiin selkeä kuva prosessijohtamisen ja prosessien roolista muutostilanteessa sekä oppimisprosessin muodostumisesta jatoteutumisesta. Johdon ja esimiesten tuen korostuminen sekä onnistunut strategisten linjausten tiedottaminen tulivat esille käytännön työssä prosessien toimivuuden ja oman työn merkityksen kautta. Tärkeänä haasteena osaamisen varmistamiseksi käyttöönoton yhteydessä oli varmistaa koulutuksen ja käyttäjäohjeiden riittävä taso ja sisältö. Käyttöönoton aikana ja sen jälkeen korostuivat tiedon jakamisessa pääkäyttäjien ja henkilöstön keskinäinen yhteistyö ja avunanto. Tehokas tiedon jakaminen mahdollisti käyttöönoton onnistumisen. Käyttöönottoon vaikutti oleellisesti myös tietotekninen näkökulma: käyttäjien kyky erottaa toisistaan oma osaaminen ja tietotekniset ongelmat. Näiden tekijöiden huomioiminen mahdollisti SAP-toiminnanohjausjärjestelmän sujuvan liikkeellelähdön Kespron tukuissa mahdollisimman vähillä operatiivisilla ongelmilla.

L’estancament que han patit històricament les comarques dels Pallars (Jussà i Sobirà) tant a nivell humà com econòmic, ha ajudat, fins fa pocs anys, a conservar fossilitzades estructures socials, religioses i humanes de diferents períodes, alhora que a nivell científic, aquest estancament té com a conseqüència la marginació quant al gruix de les investigacions que es fan a la resta del país. Es proposa en aquest treball de síntesi una anàlisi i contrastació de les dades que ens ofereix la historiografia quant al poblament i la seva evolució des de la Prehistòria fins al període tardoromà al Paratge de Montcortès i Pla de Corts (Baix Pallars, Pallars Sobirà), amb l’aportació de les darreres investigacions, encara sense publicar, que ens proporcionen, alhora que noves dades quantitatives, informació qualitativa sobre el funcionament d’aquests grups humans, és a dir, una nova perspectiva biofísica sobre la coevolució dels nous sistemes socioeconòmics amb els ecosistemes naturals en aquest territori.

BACKGROUND: In this study, we aimed at assessing Inflammatory Bowel Disease patients' needs and current nursing practice to investigate to what extent consensus statements (European Crohn's and Colitis Organization) on the nursing roles in caring for patients with IBD concur with local practice. METHODS: We used a mixed-method convergent design to combine quantitative data prospectively collected in the Swiss IBD cohort study and qualitative data from structured interviews with IBD healthcare experts. Symptoms, quality of life, and anxiety and depression scores were retrieved from physician charts and patient self-reported questionnaires. Descriptive analyses were performed based on quantitative and qualitative data. RESULTS: 230 patients of a single center were included, 60% of patients were males, and median age was 40 (range 18-85). The prevalence of abdominal pain was 42%. Self-reported data were obtained from 75 out of 230 patients. General health was perceived significantly lower compared with the general population (p < 0.001). Prevalence of tiredness was 73%; sleep problems, 78%; issues related to work, 20%; sexual constraints, 35%; diarrhea, 67%; being afraid of not finding a bathroom, 42%; depression, 11%; and anxiety symptoms, 23%. According to experts' interviews, the consensus statements are found mostly relevant with many recommendations that are not yet realized in clinical practice. CONCLUSION: Identified prevalence may help clinicians in detecting patients at risk and improve patient management. © 2015 S. Karger AG, Basel.

The evaluation of investments in advanced technology is one of the most important decision making tasks. The importance is even more pronounced considering the huge budget concerning the strategic, economic and analytic justification in order to shorten design and development time. Choosing the most appropriate technology requires an accurate and reliable system that can lead the decision makers to obtain such a complicated task. Currently, several Information and Communication Technologies (ICTs) manufacturers that design global products are seeking local firms to act as their sales and services representatives (called distributors) to the end user. At the same time, the end user or customer is also searching for the best possible deal for their investment in ICT's projects. Therefore, the objective of this research is to present a holistic decision support system to assist the decision maker in Small and Medium Enterprises (SMEs) - working either as individual decision makers or in a group - in the evaluation of the investment to become an ICT's distributor or an ICT's end user. The model is composed of the Delphi/MAH (Maximising Agreement Heuristic) Analysis, a well-known quantitative method in Group Support System (GSS), which is applied to gather the average ranking data from amongst Decision Makers (DMs). After that the Analytic Network Process (ANP) analysis is brought in to analyse holistically: it performs quantitative and qualitative analysis simultaneously. The illustrative data are obtained from industrial entrepreneurs by using the Group Support System (GSS) laboratory facilities at Lappeenranta University of Technology, Finland and in Thailand. The result of the research, which is currently implemented in Thailand, can provide benefits to the industry in the evaluation of becoming an ICT's distributor or an ICT's end user, particularly in the assessment of the Enterprise Resource Planning (ERP) programme. After the model is put to test with an in-depth collaboration with industrial entrepreneurs in Finland and Thailand, the sensitivity analysis is also performed to validate the robustness of the model. The contribution of this research is in developing a new approach and the Delphi/MAH software to obtain an analysis of the value of becoming an ERP distributor or end user that is flexible and applicable to entrepreneurs, who are looking for the most appropriate investment to become an ERP distributor or end user. The main advantage of this research over others is that the model can deliver the value of becoming an ERP distributor or end user in a single number which makes it easier for DMs to choose the most appropriate ERP vendor. The associated advantage is that the model can include qualitative data as well as quantitative data, as the results from using quantitative data alone can be misleading and inadequate. There is a need to utilise quantitative and qualitative analysis together, as can be seen from the case studies.

Although fetal anatomy can be adequately viewed in new multi-slice MR images, many critical limitations remain for quantitative data analysis. To this end, several research groups have recently developed advanced image processing methods, often denoted by super-resolution (SR) techniques, to reconstruct from a set of clinical low-resolution (LR) images, a high-resolution (HR) motion-free volume. It is usually modeled as an inverse problem where the regularization term plays a central role in the reconstruction quality. Literature has been quite attracted by Total Variation energies because of their ability in edge preserving but only standard explicit steepest gradient techniques have been applied for optimization. In a preliminary work, it has been shown that novel fast convex optimization techniques could be successfully applied to design an efficient Total Variation optimization algorithm for the super-resolution problem. In this work, two major contributions are presented. Firstly, we will briefly review the Bayesian and Variational dual formulations of current state-of-the-art methods dedicated to fetal MRI reconstruction. Secondly, we present an extensive quantitative evaluation of our SR algorithm previously introduced on both simulated fetal and real clinical data (with both normal and pathological subjects). Specifically, we study the robustness of regularization terms in front of residual registration errors and we also present a novel strategy for automatically select the weight of the regularization as regards the data fidelity term. Our results show that our TV implementation is highly robust in front of motion artifacts and that it offers the best trade-off between speed and accuracy for fetal MRI recovery as in comparison with state-of-the art methods.

The aim of this study is to examine the lifestyle characteristics and health status of the elderly in order to identify aspects that might help promote active ageing. Participants were 26 elderly citizens aged 75 or over who were the recipients of home care services in Vilafranca del Penedès (Barcelona, Spain). They were recruited by means of convenience sampling, and a case study approach was adopted. Fieldwork was conducted in April 2007, with a specially designed questionnaire administered in the context of an in-depth interview. Quantitative data were analyzed with SPSS 15, while qualitative data were analysed and grouped by category. The results indicated that 53.8% of the elderly interviewees perceived their health status as being regular, most did not have adequate nutrition and hydration, while 42.3% had chewing problems and 65.3% presented slight dependence. Most of them received visits at home, but did not go on leisure outings. The only exercise they took was walking. These findings highlight the need to promote and strengthen activities for healthy ageing, and to ensure that people over 75 receive adequate care. Programmes should be implemented to improve those aspects that are currently under-addressed.

The objective of this article is to identify differential traits of successful SMEs in comparison to average SME firms in the textile and clothing sector. The method used is the multiple case-study of 12 firms based on qualitative and quantitative data obtained by means of in-depth interviews. Building on recent academic literature, we use four main dimensions that may explain success: i) knowledge generation (R&D) and acquisition; ii) innovation activity; iii) product and market characteristics and iv) strategic characteristics. Our results indicate that a higher R&D intensity and knowledge acquisition do not explain success. The main differential characteristic is that successful firms have a higher level of innovation activity, since innovation is their strategic priority, being a result of perceiving the key success factors of their markets differently. From the analysis it also follows that the prevalent strategy of successful firms is the niche strategy, with a demand pull focus, and a high proximity to the customer
