Integrative Review: Concepts And Methods Used In Nursing


Integrative review (IR) has an international reputation in nursing research and evidence-based practice. This IR aimed at identifying and analyzing the concepts and methods recommended to undertaking IR in nursing. Nine information resources,including electronic databases and grey literature were searched. Seventeen studies were included. The results indicate that: primary studies were mostly from USA; it is possible to have several research questions or hypotheses and include primary studies in the review from different theoretical and methodological approaches; it is a type of review that can go beyond the analysis and synthesis of findings from primary studies allowing exploiting other research dimensions, and that presents potentialities for the development of new theories and new problems for research. Conclusion: IR is understood as a very complex type of review and it is expected to be developed using standardized and systematic methods to ensure the required rigor of scientific research and therefore the legitimacy of the established evidence.

Robot Manipulator Systems: Analysis and Control

Manipulator systems are rather complex and highly nonlinear which makes difficult their analysis and control. Classic system theory is veil known, however it is inadequate in the presence of strong nonlinear dynamics. Nonlinear controllers produce good results [1] and work has been done e. g. relating the manipulator nonlinear dynamics with frequency response [2–5]. Nevertheless, given the complexity of the problem, systematic methods which permit to draw conclusions about stability, imperfect modelling effects, compensation requirements, etc. are still lacking. In section 2 we start by analysing the variation of the poles and zeros of the descriptive transfer functions of a robot manipulator in order to motivate the development of more robust (and computationally efficient) control algorithms. Based on this analysis a new multirate controller which is an improvement of the well known “computed torque controller” [6] is announced in section 3. Some research in this area was done by Neuman [7,8] showing tbat better robustness is possible if the basic controller structure is modified. The present study stems from those ideas, and attempts to give a systematic treatment, which results in easy to use standard engineering tools. Finally, in section 4 conclusions are presented.

Kehitystoiminnan (RTD) systematisointi vaiheittaisen etenemisen ja portfoliojohtamisen avulla

Kehitystoimintaan liittyvä termi, innovaatio, voidaan määritellä monella eri tavalla. Riippumatta tarkasta määritelmästä innovaatioiden johtaminen voidaan määritellä prosessiksi, jossa eri suoritusvaiheet seuraavat toisiaan. Olennaista on erottaa innovaatioprosessin alkupää ja varsinainen kehitysprojekti toisistaan. Innovaatioprosessin alkupää mielletään usein sumeaksi ja vaikeasti hallittavaksi, kun taas kehitysprojektin johtamiseen on kehitetty systemaattisia menetelmiä, esimerkiksi Stage-Gate-prosessi. Kehitysprojektien johtamisessa ongelmaksi muodostuu resurssien riittämättömyys mahdollisiin projekteihin nähden. Tämä liittää kehitystoiminnan kiinteästi portfoliojohtamiseen. RTD-toiminnalla tarkoitetaan UPM Timberissä kehitystoimintaa, joka sisältää tuotekehityksen lisäksi myös prosessien ja teknologian kehitystoiminnot. UPM Timberiltä on puuttunut systemaattinen toimintamalli RTD-projektien läpiviemiseksi eikä niiden valintaan ja resurssien allokointiin ole ollut järjestelmää. Tutkimuksessa määritetään RTD-toiminnan kriittiset menestystekijät sekä muodostetaan UPM Timberille RTD-toiminnan kehityshaasteet. Niiden perusteella luodaan UPM Timberille systemaattinen toimintamalli, RTD-prosessikuvaus, RTD-projektien läpiviemiseksi sekä integroidaan portfoliojohtaminen toimintamalliin.

Personal Liberty in Psychiatric Care - Towards Service User Involvement

This study explores personal liberty in psychiatric care from a service user involvement perspective. The data were collected in four phases during the period 2000-2006 in psychiatric settings in Finland. Firstly, patient satisfaction and factors associated with user involvement were studied (n = 313). Secondly, patients’ experiences of deprivation of their liberty were explored (n = 51). Thirdly, an overview on patients’ options for lodging complaints was conducted, and all complaints (n = 4645) lodged in Finland from 2000 to 2004 were examined. Fourthly, the effects of different patient education methods on inpatients’ experiences of deprivation of liberty were tested (n = 311). It emerged that patients were quite satisfied, but reported dissatisfaction in restrictions, compulsory care and information dissemination. Patients experienced restrictions on leaving the ward and on communication, confiscation of property and coercive measures as deprivation of liberty. Patients’ experienced these interventions to be negative. In Finland, the patient complaint process is complicated and not easily accessible. In general, patient complaints increased considerably in Finland during the study period. In psychiatric care the number of complaints was quite stable and complaints led more seldom to consequences. An Internet-based patient education system was equivalent with traditional education and treatment as usual in supporting personal liberty during hospital care. This dissertation provides new information about the realization of patients' rights in psychiatric care. In order to improve patients' involvement, systematic methods to increase personal liberty during care need to be developed, the procedures for patients lodging complaints should be simplified, and patients' access to information needs to be ensured using multiple methods.

Prosessit palveluiden kehittämisen tukena pienessä tietointensiivisessä palveluyrityksessä Case: Integrata Oy

Palvelut ovat nousseet lähes kiinteäksi osaksi tuotteita sekä niiden rinnalle omaksi liiketoiminta-alueekseen. Tämän vuoksi palveluiden kehittäminen on viime vuosikymmeninä noussut sekä yritysten että akateemisten yhteisöjen mielenkiinnonkohteeksi. Menestyksekäs palveluiden kehittäminen vaatii usein systemaattisia menetelmiä, mutta menetelmien tulee antaa tilaa myös tarkoituksenmukaisille poikkeamille. Kohdeyritys pyrkii tuottamaan laadukkaita palveluita asiakastarpeet huomioiden. Tämän takia yritys haluaa kehittää olemassa olevia palveluita jatkuvasti ja pyrkii keräämään sekä työntekijöiltä että asiakkailta tietoa palvelutarpeista, joista voidaan lähteä kehittämään uusia palvelukokonaisuuksia. Tutkimus pyrkii havainnoimaan kohdeyrityksen palveluiden kehitystä ja tavoitteena on muodostaa havaintojen perusteella prosessin, jota yritys voi jatkossa hyödyntää sekä edelleen kehittää. Tutkimus on kehittävä tapaustutkimus, jonka teoreettisen viitekehyksen muodostavat uusien palveluiden kehittämisen - ja palveluinnovaatioprosessien näkökulmat. Yrityksen palveluiden kehitystä tarkastellaan kahden primaarisen aineiston sekä kahden sekundaarisen aineiston kautta. Näin ollen palveluiden kehitystä voidaan tarkastella useista näkökulmista käyttäen menetelmänä aineistotriangulaatiota. Tutkimuksessa havaittiin, että kohdeyrityksen palveluiden kehitysprosessi muodostui hyvin vastaavanlaiseksi kuin teoriaosuudessa esitettyjen uusien palveluiden kehitys- ja palveluinnovaatioprosessit. Asiakkaita ja työntekijöitä osallistettiin jonkin verran prosessin aikana. Lisäksi havaittiin, että uusien palveluiden kehitys- ja palveluinnovaatioprosessit eivät ehkä ole erillisiä kehitysprosesseja, vaikka niistä käytetäänkin eri nimityksiä kirjallisuudessa.

La propension des gestionnaires envers les évaluations participatives

Davantage d’évaluations de projets internationaux dans les pays en développement se réalisent pour informer les décisions sur la base de données probantes. L’utilisation des résultats d’évaluation est remise en cause et pour y remédier des évaluations participatives qui incluent à certaines étapes du processus évaluatif des acteurs non évaluateurs sont proposées. Parmi celles-ci, les évaluations participatives pratiques visent principalement à améliorer l’utilisation du processus et des résultats des évaluations. Ces évaluations participatives pratiques seraient obstruées par des attitudes individuelles négatives, ou résistance individuelle au changement, et favorisées par des attitudes individuelles positives, ou propension. Cette thèse propose d’étudier la propension individuelle des gestionnaires envers les évaluations participatives pratiques d’intervention (EPP), les éléments influençant cette propension, et de caractériser des niveaux de propension des individus envers les EPP. Tout d’abord une revue de littérature a proposé une définition multidimensionnelle de la propension envers les EPP comme étant une attitude favorable envers la pratique des EPP qui se décline à chaque étape d’une évaluation sous les volets affectif et cognitif. Les dimensions identifiées théoriquement étaient : apprentissage, travail en groupe, emploi de méthodes systématiques, usage de l’esprit critique. Ces dimensions ont servi de cadre pour la partie empirique de la thèse. Une étude de cas multiples avec les gestionnaires d’une institution de santé en Haïti a été menée pour contextualiser la propension et identifier les éléments d’influence. Les données ont été recueillies à l’aide d’entrevues semi-structurées et de sources documentaires. L’analyse des données concernant l’apprentissage a révélé une prédominance des formes d’apprentissage par l’action et par l’observation. Le travail en groupe se retrouve ancré dans la pratique des gestionnaires administratifs et des gestionnaires cliniques. Les méthodes systématiques se reflètent principalement dans la consultation de plusieurs acteurs ayant de l’intérêt pour la problématique immédiate à solutionner plutôt que par l’outillage méthodologique. L’emploi de méthodes systématiques prend généralement la forme de consultation élargie d’avis pour régler une situation ou prend la forme de tentative de validation des informations reçues. L’esprit critique se déclenche sous stimulation lorsque l’image individuelle, professionnelle, corporative ou organisationnelle est touchée ou lors de suggestions jugées constructives. En plus de contextualiser quatre composantes de la propension individuelle envers les EPP, les gestionnaires se sont positionnés par rapport à la propension de leurs collègues sur la base de la réactivité, plus ou moins réactif vis-à-vis des composantes de la propension individuelle. Ainsi, la propension étudiée empiriquement a laissé émerger deux axes : un axe formalisation et un axe réactivité. L’axe formalisation reprend la contextualisation des quatre composantes de la propension individuelle envers les EPP, soit la forme d’expression des composantes. L’axe réactivité reprend le niveau d’activité déployé dans chaque composante de la propension individuelle, de réactif à plus proactif. De plus, des profils d’individus ayant différents niveaux de propension envers les EPP ont été développés. Des influences favorables et défavorables au niveau de propension envers les EPP ont été identifiées. L’originalité de cette thèse tient dans le fait de se positionner dans un courant récent de réflexion autour de la résistance aux changements et aux évaluations avec un regard positif et d’avoir défini théoriquement et appliqué empiriquement le concept pluridimensionnel de propension individuelle aux EPP. Des profils de niveau de propension individuelle aux EPP et les éléments d’influence favorables et défavorables associés peuvent servir d’outil de diagnostic aux types d’évaluation possibles, servir d’ajustement à la mise en place d’évaluations selon les interlocuteurs, permettre le suivi des changements de niveaux de propension pendant une EPP et servir de sources d’informations pour ajuster les plans d’évaluations participatives.

Definição de requisitos de software baseada numa arquitetura de modelagem de negócios

Não é uma tarefa fácil definir requisitos para os sistemas de software que darão suporte a um negócio, dada a dinâmica de mudanças nos processos. O levantamento de requisitos tem sido feito de forma empírica, sem o apoio de métodos sistematizados que garantam o desenvolvimento baseado nos reais objetivos do negócio. A engenharia de software carece de métodos que tornem mais ordenadas e metódicas as etapas de modelagem de negócios e de levantamento de requisitos de um sistema. Neste artigo é apresentada uma metodologia de desenvolvimento de software resultante da incorporação de atividades propostas para modelagem de negócios e levantamento de requisitos, baseadas em uma arquitetura de modelagem de negócios. Essas atividades tornam o desenvolvimento de software mais sistemático e alinhado aos objetivos da organização, e podem ser incorporadas em qualquer metodologia de desenvolvimento baseada no UP (Unified Process - Processo Unificado).

Molecular characterization of Acidithiobacillus ferrooxidans and A-thiooxidans strains isolated from mine wastes in Brazil

Nineteen strains of Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans, including 12 strains isolated from coal, copper, gold and uranium mines in Brazil, strains isolated from similar sources in other countries and the type strains of the two species were characterized together with the type strain of A. caldus by using a combination of molecular systematic methods, namely ribotyping, BOX- and ERIC-PCR and DNA-DNA hybridization assays. Data derived from the molecular fingerprinting analyses showed that the tested strains encompassed a high degree of genetic variability. Two of the Brazilian A. ferrooxidans organisms (strains SSP and PCE) isolated from acid coal mine waste and uranium mine effluent, respectively, and A. thiooxidans strain DAMS, isolated from uranium mine effluent, were the most genetically divergent organisms. The DNA-DNA hybridization data did not support the allocation of Acidithiobacillus strain SSP to the A. ferrooxidans genomic species, as it shared only just over 40% DNA relatedness with the type strain of the species. Acidithiobacillus strain SSP was not clearly related to A. ferrooxidans in the 16S rDNA tree.

Populist Communication in the Context of European Parliament Elections 2014

Over the last decade European democracies have been facing a challenge by the rising force of new populist movements. The emergence of the financial and sovereign debt crisis in Europe created new fertile soil for the strengthening of old-established – and the development of new – populist parties in several EU-member states. José Manuel Barroso, president of the European Commission, emphasized his increased unease concerning these developments when he was speaking at the annual Brussels Think Tank Forum on 22. April 2013: “I am deeply concerned about the divisions that we see emerging: political extremes and populism tearing apart the political support and the social fabric that we need to deal with the crisis; […]” (Barroso 2013). Indeed, European elites seem to be increasingly worried by these recent developments which are perceived as an impending stress test of the Union and the project of European integration as a whole (Hartleb 2013). Sure enough, the results of the recent European Parliament Elections 2014 revealed a great support for populist political parties in many societies of EU-member countries. To understand the success of populist parties in Europe it is crucial to first shed light on the nature of populist party communication itself. Significant communicative differences may explain the varying success of populist parties between and within countries, while a pure demand-side approach (i.e. a focus on the preferences of the electorate) often fails to do so (Mudde 2010). The aim of this study is therefore to analyse what different types of populist communication styles emerge during the EP election campaign 2014 and under which conditions populist communication styles are selected by political parties. So far, the empirical measurement of populism has received only scarce attention (Rooduijn & Pauwels 2011). Besides, most of the existing empirical investigations of populism are single case studies (Albertazzi & McDonnell 2008) and scholars have not yet developed systematic methods to measure populism in a comparative way (Rooduijn & Pauwels 2011). This is a consequence of a lack of conceptual clarity which goes along with populism (Taggart 2000; Barr 2009; Canovan 1999) due to its contextual sensitivity. Hence, populism in Europe should be analysed in a way that clarifies the concept of populism and moreover takes into account that the Europeanization of politics has an influence on the type of populist party communication, which is intended in the course of that study.

A design environment for deadlock-free concurrent software

Using current software engineering technology, the robustness required for safety critical software is not assurable. However, different approaches are possible which can help to assure software robustness to some extent. For achieving high reliability software, methods should be adopted which avoid introducing faults (fault avoidance); then testing should be carried out to identify any faults which persist (error removal). Finally, techniques should be used which allow any undetected faults to be tolerated (fault tolerance). The verification of correctness in system design specification and performance analysis of the model, are the basic issues in concurrent systems. In this context, modeling distributed concurrent software is one of the most important activities in the software life cycle, and communication analysis is a primary consideration to achieve reliability and safety. By and large fault avoidance requires human analysis which is error prone; by reducing human involvement in the tedious aspect of modelling and analysis of the software it is hoped that fewer faults will persist into its implementation in the real-time environment. The Occam language supports concurrent programming and is a language where interprocess interaction takes place by communications. This may lead to deadlock due to communication failure. Proper systematic methods must be adopted in the design of concurrent software for distributed computing systems if the communication structure is to be free of pathologies, such as deadlock. The objective of this thesis is to provide a design environment which ensures that processes are free from deadlock. A software tool was designed and used to facilitate the production of fault-tolerant software for distributed concurrent systems. Where Occam is used as a design language then state space methods, such as Petri-nets, can be used in analysis and simulation to determine the dynamic behaviour of the software, and to identify structures which may be prone to deadlock so that they may be eliminated from the design before the program is ever run. This design software tool consists of two parts. One takes an input program and translates it into a mathematical model (Petri-net), which is used for modeling and analysis of the concurrent software. The second part is the Petri-net simulator that takes the translated program as its input and starts simulation to generate the reachability tree. The tree identifies `deadlock potential' which the user can explore further. Finally, the software tool has been applied to a number of Occam programs. Two examples were taken to show how the tool works in the early design phase for fault prevention before the program is ever run.

Availability estimation and management for complex processing systems

“Availability” is the terminology used in asset intensive industries such as petrochemical and hydrocarbons processing to describe the readiness of equipment, systems or plants to perform their designed functions. It is a measure to suggest a facility’s capability of meeting targeted production in a safe working environment. Availability is also vital as it encompasses reliability and maintainability, allowing engineers to manage and operate facilities by focusing on one performance indicator. These benefits make availability a very demanding and highly desired area of interest and research for both industry and academia. In this dissertation, new models, approaches and algorithms have been explored to estimate and manage the availability of complex hydrocarbon processing systems. The risk of equipment failure and its effect on availability is vital in the hydrocarbon industry, and is also explored in this research. The importance of availability encouraged companies to invest in this domain by putting efforts and resources to develop novel techniques for system availability enhancement. Most of the work in this area is focused on individual equipment compared to facility or system level availability assessment and management. This research is focused on developing an new systematic methods to estimate system availability. The main focus areas in this research are to address availability estimation and management through physical asset management, risk-based availability estimation strategies, availability and safety using a failure assessment framework, and availability enhancement using early equipment fault detection and maintenance scheduling optimization.
