PhD Students’ Research Group Networks: a Qualitative Approach

This article examines the networks within the research groups where Spanish PhD students are pursuing their doctorate. Capó et al. (2007) used quantitative data to predict PhD students’ publishing performance from their background, attitudes, supervisors’ performance and research group networks. Variables related to the research group network had a negligible explanatory power on student performance once the remaining variables had been accounted for. In this article, a qualitative follow up of the same students is carried out using extreme case sampling and indepth interviews. The qualitative research shows networking as important for students. Out of the 115 aspects that students mention in the interviews as relevant to publishing in the qualitative research, 92 have to do with their supervisors, their research group or their network as a whole. Similarly, out of the 50 hindrances mentioned, 20 have to do with the networks or relations. The most commonly mentioned network-related topics are research group members pushing PhD students to publish, meeting researchers outside the research group, existence of other PhD students in the group, help with the PhD from group members, supervisor’s interest in the thesis, the possibility of discussing with experts on the PhD’s topic and frequent contact with the supervisor and research group members. Some of these characteristics were not, however, measured in the conventional quantitative social network survey

Characteristics of credit risk assessment methods of major Nordic banks in allocating capital when extending credits to large corporations

Credit risk assessment is an integral part of banking. Credit risk means that the return will not materialise in case the customer fails to fulfil its obligations. Thus a key component of banking is setting acceptance criteria for granting loans. Theoretical part of the study focuses on key components of credit assessment methods of Banks in the literature when extending credits to large corporations. Main component is Basel II Accord, which sets regulatory requirement for credit risk assessment methods of banks. Empirical part comprises, as primary source, analysis of major Nordic banks’ annual reports and risk management reports. As secondary source complimentary interviews were carried out with senior credit risk assessment personnel. The findings indicate that all major Nordic banks are using combination of quantitative and qualitative information in credit risk assessment model when extending credits to large corporations. The relative input of qualitative information depends on the selected approach to the credit rating, i.e. point-in-time or through-the-cycle.

An examination of factors influencing ERP key-user satisfaction: A qualitative case study

Several companies are trying to improve their operation efficiency by implementing an enterprise resource planning (ERP) system that makes it possible to control the resources of the company in real time. However, the success of the implementation project is not a foregone conclusion; a significant part of these projects end in a failure, one way or another. Therefore it is important to investigate ERP system implementation more closely in order to increase understanding about factors influencing ERP system success and to improve the probability of a successful ERP implementation project. Consequently, this study was initiated because a manufacturing case company wanted to review the success of their ERP implementation project. To be exact, the case company hoped to gain both information about the success of the project and insight for future implementation improvement. This study investigated ERP success specifically by examining factors that influence ERP key-user satisfaction. User satisfaction is one of the most commonly applied indicators of information system success. The research data was mainly collected by conducting theme interviews. The subjects of the interviews were six key-users of the newly implemented ERP system. The interviewees were closely involved in the implementation project. Furthermore, they act as representative users that utilize the new system in everyday business processes. The collected data was analyzed by thematizing. Both data collection and analysis were guided by a theoretical frame of reference. This frame was based on previous research on the subject. The results of the study aligned with the theoretical framework to large extent. The four principal factors influencing key-user satisfaction were change management, contractor service, key-user’s system knowledge and characteristics of the ERP product itself. One of the most significant contributions of the research is that it confirmed the existence of a connection between change management and ERP key-user satisfaction. Furthermore, it discovered two new sub-factors influencing contractor service related key-user satisfaction. In addition, the research findings indicated that in order to improve the current level of key-user satisfaction, the case company should pay special attention to system functionality improvement and enhancement of the key-users’ knowledge. During similar implementation projects in the future, it would be important to assure the success of change management and contractor service related processes.

Weld joint characteristics by nano-materials addition

The need for industries to remain competitive in the welding business, has created necessity to develop innovative processes that can exceed customer’s demand. Significant development in improving weld efficiency, during the past decades, still have their drawbacks, specifically in the weld strength properties. The recent innovative technologies have created smallest possible solid material known as nanomaterial and their introduction in welding production has improved the weld strength properties and to overcome unstable microstructures in the weld. This study utilizes a qualitative research method, to elaborate the methods of introducing nanomaterial to the weldments and the characteristic of the welds produced by different welding processes. The study mainly focuses on changes in the microstructural formation and strength properties on the welded joint and also discusses those factors influencing such improvements, due to the addition of nanomaterials. The effect of nanomaterial addition in welding process modifies the physics of joining region, thereby, resulting in significant improvement in the strength properties, with stable microstructure in the weld. The addition of nanomaterials in the welding processes are, through coating on base metal, addition in filler metal and utilizing nanostructured base metal. However, due to its insignificant size, the addition of nanomaterials directly to the weld, would poses complications. The factors having major influence on the joint integrity are dispersion of nanomaterials, characteristics of the nanomaterials, quantity of nanomaterials and selection of nanomaterials. The addition of nanomaterials does not affect the fundamental properties and characteristics of base metals and the filler metal. However, in some cases, the addition of nanomaterials lead to the deterioration of the joint properties by unstable microstructural formations. Still research are ongoing to achieve high joint integrity, in various materials through different welding processes and also on other factors that influence the joint strength.

Behavioural characteristics in phylogenetics : a case study using black fly (Diptera: Simuliidae) cocoon spinning behaviour

1-1 is torically, the predominan t method of reconstructing phylogenies has been through the use of morphological characters. There are new techniques now gaining acceptance, including molecular techniques al1d chromosomal information. Altl10ugh the study of behaviour has been used in a comparative framework, these analyses have, historically, been based on intuition. Hennig (1966) devised a neV\' method of reconstructing phylogenies which provided a 110ncircular method for formulating, testing and refining phylogenies. Subsequent s)Tstematists had virtually abandoned ecological and beha\lioural data as primary indicators of phylogenetic relationships (Brooks and McLennan 1991). Therefore, in a modern cladistic framework (sensu Hennig) the analysis of behavioural traits remains underrepresented as a method of reconstructing phylogenies. This thesis will reconstruct the phylogeny for species of black flies (Diptera: Simuliidae), using two steps. The first step is to thoroughl)' understand and explain the cocoon spinning in black fly larvae. There have bee115 previous descriptions of cocoon spinning, but all were incomplete or erroneous. The advances in technology, including video recorders and VCRs, have allowed this behaviour to be analyzed in great detail in 20 different species. A complete description of the cocoon spinning of Simulium \littatum is given. This description will be used as a template for the other species observed. The description and understanding of cococ)n spinning was the first step in undertaking a phylogenetic analysis using this behaviour. The behaviour was then broken down and analyzed, revealing 23 characters, 3 either qualitative and quantitative in nature. These characters were assessed in a cladistic framework (sensu Hennig) and a phylogenetic tree was reconstructed with a e.I of 0.91 and an R.I. of 0.96. This phylogenetic tree closely resembles a previously established pllylogenetic tree produced from morphological and cytological information. The importance of this result is the indication that, contrary to some authors, behavioural characters, if used properly, can add very informative characters to a data set.

Ten years after : a qualitative study of students' experiences in a high school theatre company

This qualitative study explored 4 former students' perceptions of the learning associated with their involvement in a high school theatre program and the contextual factors they linked to their perceived development. The study involved 4 adult participants, 2 male and 2 female, who had participated extensively in a high school theatre company from 1996 to 2001 when they were students in a large Ontario school board. Data were collected from January to August, 2007, when the 4 former students took part in two in-depth, open-ended interviews. The focus of investigation was participant perspectives. Data analysis revealed that the 4 participants' involvement in high school theatre produced both wide-ranging and enduring developmental benefits across personal, social, and cognitive domains. Participants achieved these benefits through interactions among 3 related contexts: (a) rehearsal and performance practices, (b) the world of the play, and (c) characteristics of the high school theatre company.

Étude qualitative de la force mentale menée auprès d’athlètes québécois francophones de niveau universitaire

L’objectif de cette étude était d’obtenir une meilleure compréhension du concept de force mentale appliqué dans un contexte sportif. Pour se faire, des entrevues ont été réalisées avec dix athlètes québécois francophones de niveau universitaire. L’analyse des données s’est effectuée en suivant les principes de la version abrégée de la théorisation ancrée. Les résultats appuient globalement la littérature scientifique. En somme, la force mentale serait composée de caractéristiques de base interreliées, telles que la motivation internalisée, la confiance en soi, la maturité et la détermination. La force mentale serait sollicitée non seulement lorsque l’athlète fait face à des situations difficiles comme l’adversité, mais également lorsque le contexte dans lequel il évolue est exempt de complications (à l’entraînement ou lors de victoire). Les résultats des entrevues indiquent que face à ces deux types de situation, les athlètes forts mentalement possèderaient un mode réactionnel tridimensionnel (dimension cognitive, affective et comportementale) se caractérisant par la gestion et le contrôle de l’attention, l’interprétation optimiste des situations, le contrôle de l’activation et du langage corporel, la gestion des émotions et la résilience. Contrairement à la littérature, les résultats suggèrent que la force mentale ne serait pas nécessairement liée aux athlètes performants au plus haut niveau de leur sport, mais à la capacité des athlètes à donner de bonnes performances en fonction de leur potentiel individuel. Cette étude constitue le premier pas vers le développement d’un instrument de mesure permettant d’évaluer le niveau de force mentale chez les athlètes francophones.

The influence of primary care clinic characteristics on the quality of care for depression in patients with different comorbidity profiles

Dans les services de première ligne, la majorité des personnes atteintes de dépression souffrent également d’autres maladies chroniques comorbides. Offrir des soins de haute qualité à ces patients représente un défi important pour les intervenants en première ligne ainsi que pour le système de santé. Il y a des raisons de croire que les contextes organisationnels dans lesquels les intervenants pratiquent ont une influence importante sur les soins. Cependant, peu d’études ont examiné directement la façon dont les caractéristiques des cliniques facilitent ou entravent les soins offerts aux patients atteints de dépression et de différents types de maladies chroniques comorbides. L’objectif général de ce projet de recherche était donc de mieux comprendre comment différentes caractéristiques des cliniques de première ligne influencent la qualité des soins pour la dépression chez des patients ayant différents profils de comorbidité. La thèse comporte deux études. Tout d'abord, nous avons effectué une revue systématique examinant les relations entre la comorbidité physique chronique et la qualité des soins pour la dépression dans les services de première ligne afin de clarifier la nature de ces relations et d’identifier les facteurs qui pourraient influer sur ces relations. Ensuite, nous avons effectué une étude aux méthodes mixtes ayant deux volets : (a) un volet quantitatif examinant les relations entre la qualité des soins pour la dépression, les profils de comorbidité des patients, et les caractéristiques des cliniques de première ligne par le biais d’analyses de régression multiniveaux de données issues de deux enquêtes, et (b) un volet qualitatif basé sur une étude de cas explorant les perceptions des professionnels des services de première ligne sur les facteurs organisationnels pouvant influencer la qualité des soins offerts aux patients souffrant de dépression et d’autres maladies chroniques comorbides. Les résultats de ces études ont montré que, bien que la qualité des soins de la dépression en soins primaires soit sous-optimale, certains sous-groupes de patients dépressifs sont plus à risque que d’autres de recevoir des soins pour la dépression inadéquats, notamment des patients ayant uniquement des comorbidités chroniques physiques. Cependant, plusieurs caractéristiques des cliniques de première ligne semblent faciliter l’offre de soins de qualité aux patients atteints de dépression et de maladies chroniques comorbides : les normes et les valeurs liées au travail d'équipe et le soutien mutuel, l'accès au soutien des professionnels ayant une expertise en santé mentale, l’utilisation des algorithmes de traitement et d’autres outils d’aide à la décision pour la dépression, et l’absence d’obstacles liés aux modèles de rémunération inadéquats. Une des façons dont ces caractéristiques favorisent la qualité est en facilitant la circulation des connaissances dans les cliniques de première ligne. Nos résultats suggèrent que des interventions organisationnelles ciblées sont nécessaires pour améliorer la qualité des soins pour la dépression que reçoivent les patients ayant des maladies chroniques comorbides. Ces interventions peuvent viser différents domaines organisationnels (ex : caractéristiques structurelles/stratégiques, sociales, technologies et épistémiques) mais doivent aussi prendre en compte comment les éléments de chaque domaine interagissent et comment ils pourraient influencer les soins pour des patients ayant des profils de comorbidité différents.

Biomimicry and innovation in sustainable design : understanding its innovation supporting characteristics compared to ecodesign

Depuis la dernière décennie, le biomimétisme est une discipline en plein essor dans le monde du design durable. De plus en plus, cette stratégie prend place dans plusieurs facettes du design, que ce soit dans le design industriel, dans l’architecture ou encore dans le design urbain. Le livre de Janine Benyus intitulé Biomimétisme: Quand la Nature Inspire des Innovations Durables (1997) est largement reconnu comme étant le catalyseur de la stratégie et comme l’indique le titre du livre, le biomimétisme est très souvent associé à l’innovation. Le but principal de cette recherche est de mieux comprendre le lien entre le biomimétisme et l’innovation. Cette recherche sur le biomimétisme comprend un objectif mineur et deux objectifs majeurs. Le premier objectif cherche à comprendre le véritable lien entre le biomimétisme et l’écodesign. Le second objectif vise non seulement à valider la théorie selon laquelle le biomimétisme est une stratégie menant à des solutions de design innovantes, mais également à établir quels types d’innovations ont été générés par cette stratégie. Finalement, le troisième objectif est d’identifier les aspects du biomimétisme qui mènent à des solutions de design innovantes. Pour accomplir ces objectifs, cette recherche utilisera une approche qualitative supportée par des études de cas et une revue de littérature. Afin de contextualiser les deux derniers objectifs, cette étude établit que le biomimétisme et l’écodesign sont des stratégies complémentaires plutôt qu’en compétition. Les conclusions de cette recherche démontrent que la théorie proposant que le biomimétisme soit une stratégie d’innovation est valide et que la discipline est surtout apte à générer l’innovation radicale. Finalement, la recherche indique que l’analogie de distance et la transdisciplinarité sont les deux aspects du biomimétisme aidant à produire des solutions de design innovantes. Le biomimétisme est mieux connu dans le contexte du design durable et cette recherche permet de mieux comprendre le biomimétisme dans le contexte de l’innovation. Considérant que le biomimétisme est une discipline qui suscite beaucoup d’intérêt des milieux académiques et privés, cette recherche participe à l’expansion de la connaissance sur le sujet et propose de nouvelles pistes de recherche sur le biomimétisme et l’innovation.

Qualitative air flow modelling and analysis of data centre air conditioning as multiple jet array

This work identifies the importance of plenum pressure on the performance of the data centre. The present methodology followed in the industry considers the pressure drop across the tile as a dependant variable, but it is shown in this work that this is the only one independent variable that is responsible for the entire flow dynamics in the data centre, and any design or assessment procedure must consider the pressure difference across the tile as the primary independent variable. This concept is further explained by the studies on the effect of dampers on the flow characteristics. The dampers have found to introduce an additional pressure drop there by reducing the effective pressure drop across the tile. The effect of damper is to change the flow both in quantitative and qualitative aspects. But the effect of damper on the flow in the quantitative aspect is only considered while using the damper as an aid for capacity control. Results from the present study suggest that the use of dampers must be avoided in data centre and well designed tiles which give required flow rates must be used in the appropriate locations. In the present study the effect of hot air recirculation is studied with suitable assumptions. It identifies that, the pressure drop across the tile is a dominant parameter which governs the recirculation. The rack suction pressure of the hardware along with the pressure drop across the tile determines the point of recirculation in the cold aisle. The positioning of hardware in the racks play an important role in controlling the recirculation point. The present study is thus helpful in the design of data centre air flow, based on the theory of jets. The air flow can be modelled both quantitatively and qualitatively based on the results.

The regulation of Internet content. A qualitative, Colombian and comparative law study

 The incursion of Internet has created new forms of information and communication. As a result, today’s generation is culturally socialized by the influence of information and communication technologies in their various forms. This has generated a series of characteristics of social and cultural behaviour which are derivative of didactic, academic or recreational use. Nevertheless the use of the Internet from an early age represents not only a useful educational tool; it can constitute a great danger when it is used to access contents unsuitable for their adaptive development. Accordingly, it is necessary to study the legal regulation of internet content and to evaluate how such regulation may affect rights. Further, it is also important to study of the impact and use of this technological tool at level of the familiar unit, to understand better how it can suggest appropriate social mechanisms for the constructive use of Internet. The present investigation involves these two aspects with the purpose of uniting the legal and social perspective in a joint analysis that allows one more a more integral vision of this problem of great interest at the global level. 

Emotional characteristics of psychology students: a study based on the formative research perspective

In the formative research scheme, the author built a psychological scale, with the purpose of analyzing psychological characteristics of the School of Psychology students. The instrument showed a high reliability coefficient (α=0,86), the exploratory factorial analysis found five variables which allowed to predict some aspects of sex and career level through a logistic regression; the ALSCAL showed two emotional dimensions. The author recommends to improve the instrument and to continue its application in the School. It is also necessary to develop qualitative research to acquire new data about the topic of the research.

PhD Students’ Research Group Networks: a Qualitative Approach

This article examines the networks within the research groups where Spanish PhD students are pursuing their doctorate. Capó et al. (2007) used quantitative data to predict PhD students’ publishing performance from their background, attitudes, supervisors’ performance and research group networks. Variables related to the research group network had a negligible explanatory power on student performance once the remaining variables had been accounted for. In this article, a qualitative follow up of the same students is carried out using extreme case sampling and indepth interviews. The qualitative research shows networking as important for students. Out of the 115 aspects that students mention in the interviews as relevant to publishing in the qualitative research, 92 have to do with their supervisors, their research group or their network as a whole. Similarly, out of the 50 hindrances mentioned, 20 have to do with the networks or relations. The most commonly mentioned network-related topics are research group members pushing PhD students to publish, meeting researchers outside the research group, existence of other PhD students in the group, help with the PhD from group members, supervisor’s interest in the thesis, the possibility of discussing with experts on the PhD’s topic and frequent contact with the supervisor and research group members. Some of these characteristics were not, however, measured in the conventional quantitative social network survey

Predictors of knowledge creation performance. A quantitative qualitative comparative study of European doctorandi

Aquesta tesi forma part d'un projecte destinat a predir el rendiment acadèmic dels estudiants de doctorat portat a terme per l'INSOC (International Network on Social Capital and Performance). El grup de recerca INSOC està format per les universitats de Girona (Espanya), Ljubljana (Eslovènia), Giessen (Alemanya) i Ghent (Bèlgica). El primer objectiu d'aquesta tesi és desenvolupar anàlisis quantitatius comparatius sobre el rendiment acadèmic dels estudiants de doctorat entre Espanya, Eslovènia i Alemanya a partir dels resultats individuals del rendiment acadèmic obtinguts de cada una de les universitats. La naturalesa internacional del grup de recerca implica la recerca comparativa. Vam utilitzar variables personal, actitudinals i de xarxa per predir el rendiment. El segon objectiu d'aquesta tesi és entendre de manera qualitativa perquè les variables de xarxa no ajuden quantitativament a predir el rendiment a la universitat de Girona (Espanya). En el capítol 1, definim conceptes relacionats amb el rendiment i donam un llistat de cada una de les variables independents (variables de xarxa, personals i actitudinals), resumint la lliteratura. Finalment, explicam com s'organitzen els estudis de doctorat a cada un dels diferents països. A partir d'aquestes definicions teòriques, en els pròxims capítols, primer presentarem els qüestionaris utilitzats a Espanya, Eslovènia i Alemanya per mesurar aquests diferents tipus de variables. Després, compararem les variables que són relevants per predir el rendiment dels estudiants de doctorat a cada país. Després d'això, fixarem diferents models de regressió per predir el rendiment entre països. En tots aquests models les variables de xarxa fallen a predir el rendiment a la Universitat de Girona. Finalment, utilitzem estudis qualitatius per entendre aquests resultats inesperats. En el capítol 2, expliquem com hem dissenyat i conduït els qüestionaris en els diferents països amb l'objectiu d'explicar el rendiment dels estudiants de doctorat obtinguts a Espanya, Eslovènia i Alemanya. En el capítol 3, cream indicadors comparables però apareixen problemes de comparabilitat en preguntes particulars a Espanya, Eslovènia i Alemanya. En aquest capítol expliquem com utilitzem les variables dels tres països per crear indicadors comparables. Aquest pas és molt important perquè el principal objectiu del grup de recerca INSOC és comparar el rendiment dels estudiants de doctorat entre els diferents països. En el capítol 4 comparem models de regressió obtinguts de predir el rendiment dels estudiants de doctorat a les universitats de Girona (Espanya) i Eslovènia. Les variables són característiques dels grups de recerca dels estudiants de doctorat enteses com una xarxa social egocèntrica, característiques personals i actitudinals dels estudiants de doctorat i algunes carecterístiques dels directors. Vam trobar que les variables de xarxa egocèntriques no predien el rendiment a la Universitat de Girona. En el capítol 5, comparem dades eslovenes, espanyoles i alemnayes, seguint la metodologia del capítol 4. Concluïm que el cas alemany és molt diferent. El poder predictiu de les variables de xarxa no millora. En el capítol 6 el grup de recerca dels estudiants de doctorat és entès com una xarxa duocèntrica (Coromina et al., 2008), amb l'objectiu d'obtendre informació de la relació mútua entre els estudiants i els seus directors i els contactes d'ambdós amb els altres de la xarxa. La inclusió de la xarxa duocèntrica no millora el poder predictiu del model de regressió utilitzant les variales egocèntriques de xarxa. El capítol 7 pretèn entendre perquè les variables de xarxa no predeixen el rendiment a la Universitat de Girona. Utilitzem el mètode mixte, esperant que l'estudi qualitatiu pugui cobrir les raons de perquè la qualitat de la xarxa falla en la qualitat del treball dels estudiants. Per recollir dades per l'estudi qualitatiu utilitzem entrevistes en profunditat.

The causes of prescribing errors in English general practices: a qualitative study

Aim: To examine the causes of prescribing and monitoring errors in English general practices and provide recommendations for how they may be overcome. Design: Qualitative interview and focus group study with purposive sampling and thematic analysis informed by Reason’s accident causation model. Participants: General practice staff participated in a combination of semi-structured interviews (n=34) and six focus groups (n=46). Setting: Fifteen general practices across three primary care trusts in England. Results: We identified seven categories of high-level error-producing conditions: the prescriber, the patient, the team, the task, the working environment, the computer system, and the primary-secondary care interface. Each of these was further broken down to reveal various error-producing conditions. The prescriber’s therapeutic training, drug knowledge and experience, knowledge of the patient, perception of risk, and their physical and emotional health, were all identified as possible causes. The patient’s characteristics and the complexity of the individual clinical case were also found to have contributed to prescribing errors. The importance of feeling comfortable within the practice team was highlighted, as well as the safety of general practitioners (GPs) in signing prescriptions generated by nurses when they had not seen the patient for themselves. The working environment with its high workload, time pressures, and interruptions, and computer related issues associated with mis-selecting drugs from electronic pick-lists and overriding alerts, were all highlighted as possible causes of prescribing errors and often interconnected. Conclusion: This study has highlighted the complex underlying causes of prescribing and monitoring errors in general practices, several of which are amenable to intervention.
