Portfolioajattelu ostostrategian kehittämisessä Case: VR Konserni

Tutkimuksen tavoitteena oli selvittää portfolioajattelun hyödyntämistä yrityksen ostostrategian kehittämisessä. Teoreettisen portfolioajattelun soveltamista käytännössä selvitettiin tavallisten tuotteiden ostostrategian kehittämisprosessissa kohdeyrityksessä. Tutkimus toteutettiin kuvailevana case tutkimuksena, jossa aineiston kokoaminen pohjautui aineistotriangulaatioon. Analysointi toteutettiin ostostrategian päätösprosessin kuvaamisella sekä asetettujen esioletusten toteutumisen tutkimisella. Portfolioajattelua hyödynnettiin tutkitussa konserniyhtiössä liiketoimintayksiköiden ostotoimintojen integroimisella: toteuttamalla oston yhtenäisiä toimintatapoja konsernitasolla, yhteen sovittamalla oston tietojärjestelmäratkaisuja sisäisesti sekä kytkemällä konsernin ostojärjestelmä joustavasti ostomarkkinoille. Keskeisenä tutkimustuloksena on perinteisestä aihealueen teoriasta poikkeava havainto, jonka mukaan tavallisten tuotteiden ostostrategiassa painopiste on siirtymässä spot - ostoista ja jatkuvasta kilpailuttamisesta pitkäaikaisempiin sopimuksiin ja tiiviimpään yhteistyöhön toimittajien kanssa. Tähän on vaikuttamassa erityisesti sähköisen ostamisen järjestelmien käyttöönotto.

An Economic Analysis of the Legal Concept of Trustees' Power of Investment

Authorised trustee status is a legal concept which has economic implications; one of the major implications is that it assists in the direction of investment funds into particular securities and areas of the economy. The concept of authorised trustee status, while attempting to achieve specific outcomes for the beneficiaries of trusts cannot be relied upon to secure these results. Economic analysis of the role of the trustee maintains that this role is one of portfolio manager; a role which is complex but which is explicable in terms of definable procedures and practices. The role of trustee as portfolio manager is one which requires greater financial knowledge than can be assumed is possessed by all trustees. The trustee as portfolio manager is required to maintain a review of decisions make under powers to invest trust assets. A solution to the problem of authorised trustee status is proposed. The solution takes two parts: the first is the adoption of the prudent person approach but with the codification of duties of the trustee and the explicit listing of the factors that a trustee should consider in using the investment powers. The second part of the proposed solution is to link the investment powers of trustees to the best practice features of securities advisers who are now licensed by a regulatory body, the Australian Securities and Investment Commission.

An electronic portfolio for quantitative assessment of surgical skills in undergraduate medical education.

BACKGROUND We evaluated a newly designed electronic portfolio (e-Portfolio) that provided quantitative evaluation of surgical skills. Medical students at the University of Seville used the e-Portfolio on a voluntary basis for evaluation of their performance in undergraduate surgical subjects. METHODS Our new web-based e-Portfolio was designed to evaluate surgical practical knowledge and skills targets. Students recorded each activity on a form, attached evidence, and added their reflections. Students self-assessed their practical knowledge using qualitative criteria (yes/no), and graded their skills according to complexity (basic/advanced) and participation (observer/assistant/independent). A numerical value was assigned to each activity, and the values of all activities were summated to obtain the total score. The application automatically displayed quantitative feedback. We performed qualitative evaluation of the perceived usefulness of the e-Portfolio and quantitative evaluation of the targets achieved. RESULTS Thirty-seven of 112 students (33%) used the e-Portfolio, of which 87% reported that they understood the methodology of the portfolio. All students reported an improved understanding of their learning objectives resulting from the numerical visualization of progress, all students reported that the quantitative feedback encouraged their learning, and 79% of students felt that their teachers were more available because they were using the e-Portfolio. Only 51.3% of students reported that the reflective aspects of learning were useful. Individual students achieved a maximum of 65% of the total targets and 87% of the skills targets. The mean total score was 345 ± 38 points. For basic skills, 92% of students achieved the maximum score for participation as an independent operator, and all achieved the maximum scores for participation as an observer and assistant. For complex skills, 62% of students achieved the maximum score for participation as an independent operator, and 98% achieved the maximum scores for participation as an observer or assistant. CONCLUSIONS Medical students reported that use of an electronic portfolio that provided quantitative feedback on their progress was useful when the number and complexity of targets were appropriate, but not when the portfolio offered only formative evaluations based on reflection. Students felt that use of the e-Portfolio guided their learning process by indicating knowledge gaps to themselves and teachers.

Digital learner portfolio as a tool for inovating assessment in the European Higher Education Area

The present article comes from a doctoral thesis that turns on digital learner portfolio, which is an innovating methodology from the perspective of European Higher Education Area. First, the educative concept of eportfolio is described in the sense of its procedure and its structure, by means of the technological support of a platform of virtual campus. Second, it is shown the pedagogical model of an eportfolio that adapts subjects with an instrumental character to one organization based on tasks and reflections. This design of virtual learning environment is based on a teaching- learning methodology sustained in the activity of the student, which tries to give support to the management of his or her own process of learning and assessment. Finally, the article illustrates the experience of implementation of the first digital learner portfolios in the University of Barcelona and the Autonomous University of Barcelona, with the objective of reflecting about the pedagogical consequences that this assessment model with technological support has in a traditional higher education institution.

Conception d’un portfolio électronique pour évaluer les compétences des élèves du programme Arts, lettres et communication

Le ministère de l’Enseignement supérieur, de la Recherche, de la Science et de la Technologie (MERST) du Québec a modifié en 2013 le programme pré universitaire Arts, lettres et communication. Le cégep de La Pocatière a décidé de donner l’option médias. Les compétences du programme sont réparties dans 11 cours. Cette réalité nous a amenée à chercher une solution afin de permettre à l’étudiante ou à l’étudiant de réaliser un bilan de ses compétences et à l’enseignante ou à l’enseignant d’évaluer la compétence d’intégration des acquis du programme dans le cours porteur de l’épreuve synthèse de programme. C’est pour cela que l’objet de cet essai de maîtrise porte sur la conception d’un portfolio d’évaluation électronique pour documenter les compétences des élèves du programme Arts, lettres et communication, option médias. Un nouveau programme appelle de nouvelles pratiques de toutes sortes dont évaluatives. De plus, les étudiantes et les étudiants de la génération C sont très attirés par les technologies. De là, l’idée d’un portfolio d’évaluation électronique. Par ailleurs, les études réalisées jusqu’à présent sur le portfolio peuvent servir de sources d’inspiration. Notamment, celle de France Côté où le portfolio porte sur un cours, celle de Ginette Bousquet qui a pour objet un portfolio d’apprentissage et celle de Nathalie Martin qui présente un portfolio vérifiant l’acquisition de deux compétences (morcelées sur plusieurs sessions) d’un programme technique. Toutefois, elles ne répondent pas au besoin pressenti d’évaluer la compétence d’intégration des acquis qui suggère d’évaluer toutes les compétences du programme pré-universitaire. L’objectif général du présent essai est de concevoir un outil d’évaluation permettant à l’étudiante ou à l’étudiant de recueillir les preuves de ses compétences dans le but d’en faire un bilan au terme du programme Arts, lettres et communication, option médias dans le cadre du cours porteur de l’épreuve synthèse de programme : Projet médiatique II. Pour ce faire, le cadre de référence a été formé. Il porte sur le concept de compétence, l’évaluation des compétences, l’autoévaluation, le portfolio, le portfolio d’évaluation et le portfolio électronique. De plus, il intègre les objectifs spécifiques suivants : 1. Concevoir un portfolio électronique pour évaluer les compétences de l’étudiante ou de l’étudiant dans le cadre du programme Arts, lettres et communication, option médias; 2. Valider le portfolio électronique pour évaluer les compétences de l’étudiante ou de l’étudiant dans le cadre du programme Arts, lettres et communication, option médias. La méthodologie retenue se situe dans le pôle de l’innovation pédagogique. Il s’agit d’une recherche de développement s’appuyant sur les étapes de Van der Maren (2014). La méthodologie est qualitative et le paradigme interprétatif. Nous avons d’abord conçu le prototype en nous appuyant sur le cadre de référence afin d’en retirer les éléments essentiels d’un portfolio et nous avons appliqué les phases de Van der Maren. Puis, nous l’avons soumis aux critiques de quatre juges-experts. Les données recueillies par un questionnaire et une entrevue complémentaire, après analyse, ont amené des modifications du prototype. Tout cela a permis de concevoir le portfolio d’évaluation électronique et le Guide de réalisation qui en est la structure. Les résultats laissent transparaître notamment que pour faire élaborer un portfolio d’évaluation électronique, l’étudiante ou l’étudiant aura avantage à être accompagné par un Guide de réalisation conçu par son enseignante ou son enseignant. Aussi, que le support électronique est une plus-value. De plus, que le portfolio d’évaluation électronique permet un bilan de toutes les compétences, de pratiquer l’autoévaluation et surtout, qu’il s’agit d’un outil pertinent d’évaluation des compétences. Le portfolio d’évaluation électronique sera mis à l’essai à l’hiver 2016 dans le cadre du cours porteur de l’épreuve synthèse de programme (ESP).

An Integrated Framework To Improve The Concept Of Resource Specialisation.

Resource specialisation, although a fundamental component of ecological theory, is employed in disparate ways. Most definitions derive from simple counts of resource species. We build on recent advances in ecophylogenetics and null model analysis to propose a concept of specialisation that comprises affinities among resources as well as their co-occurrence with consumers. In the distance-based specialisation index (DSI), specialisation is measured as relatedness (phylogenetic or otherwise) of resources, scaled by the null expectation of random use of locally available resources. Thus, specialists use significantly clustered sets of resources, whereas generalists use over-dispersed resources. Intermediate species are classed as indiscriminate consumers. The effectiveness of this approach was assessed with differentially restricted null models, applied to a data set of 168 herbivorous insect species and their hosts. Incorporation of plant relatedness and relative abundance greatly improved specialisation measures compared to taxon counts or simpler null models, which overestimate the fraction of specialists, a problem compounded by insufficient sampling effort. This framework disambiguates the concept of specialisation with an explicit measure applicable to any mode of affinity among resource classes, and is also linked to ecological and evolutionary processes. This will enable a more rigorous deployment of ecological specialisation in empirical and theoretical studies.

Photoelastic Analysis Of All-on-four Concept Using Different Implants Angulations For Maxilla.

Conventional tilted implants are used in oral rehabilitation for heavily absorbed maxilla to avoid bone grafts; however, few research studies evaluate the biomechanical behavior when different angulations of the implants are used. The aim of this study was evaluate, trough photoelastic method, two different angulations and length of the cantilever in fixed implant-supported maxillary complete dentures. Two groups were evaluated: G15 (distal tilted implants 15°) and G35 (distal tilted implants 35°) n = 6. For each model, 2 distal tilted implants (3.5 x 15 mm long cylindrical cone) and 2 parallel tilted implants in the anterior region (3.5 x 10 mm) were installed. Photoelastic models were submitted to three vertical load tests: in the end of cantilever, in the last pillar and in the all pillars at the same time. We obtained the shear stress by Fringes software and found values for total, cervical and apical stress. The quantitative analysis was performed using the Student tests and Mann-Whitney test; p ≥ 0.05. There is no difference between G15 and G35 for total stress regardless of load type. Analyzing the apical region, G35 reduced strain values considering the distal loads (in the cantilever p = 0.03 and in the last pillar p = 0.02), without increasing the stress level in the cervical region. Considering the load in all pillars, G35 showed higher stress concentration in the cervical region (p = 0.04). For distal loads, G15 showed increase of tension in the apical region, while for load in all pillars, G35 inclination increases stress values in the cervical region.

[recovery: Systematic Review Of A Concept].

The concept of recovery has been described in papers as a state of psychic, physical and social recuperation of day-to-day functions. The scope of this article is to analyze the concepts of the term in different research methodologies and the paradigmatic evolution of the recovery concept. Systematic bibliographical research was conducted in the Pubmed database using the words recovery + schizophrenia limited to freely available full papers published in the previous two years. Nineteen papers were analyzed. The majority of the papers sought associations between characteristic data and recovery; few papers discussed the concept in a way to distinguish it from other words like cure or rehabilitation. Recovery as a state in which people with severe mental illness can feel like the creators of their own itinerary tend to be found in qualitative studies and in bibliographic reviews in which the meaning of recovery is not related to the lack of symptoms and tends to prioritize how participative the life of an individual can be despite the disease. Some quantitative studies detect this conceptual difference. In qualitative research there is an increase in the concept of recovery and in ways of promoting it.

Effective coordination concept applied for phase change (GeTe)(m)(Sb(2)Te(3))(n) compounds

In this work, we employed the effective coordination concept to study the local environments of the Ge, Sb, and Te atoms in the Ge(m)Sb(2n)Te(m+3n) compounds. From our calculations and analysis, we found an average effective coordination number (ECN) reduction of 1.59, 1.42, and 1.37, for the Ge, Sb, Te atoms in the phase transition from crystalline, ECN=5.55 (Ge), 5.73 (Sb), 4.37 (Te), to the amorphous phase, ECN=3.96 (Ge), 4.31 (Sb), 3.09 (Te), for the Ge(2)Sb(2)Te(5) composition. Similar changes are observed for other compositions. Thus, our results indicate that the coordination changes from the crystalline to amorphous phase are not large as previously assumed in the literature, i.e., from sixfold to fourfold for Ge, which can contribute to obtain a better understanding of the crystalline to amorphous phase transition.

Dignified death: Concept development involving nurses and doctors in Pediatric Intensive Care Units

The aim of this study was to develop the concept of the dignified death of children in Brazilian pediatric intensive care units (PICUs). The Hybrid Model for Concept Development was used to develop a conceptual structure of dignified death in PICUs in an attempt to define the concept. The fieldwork study was carried out by means of in-depth interviews with nine nurses and seven physicians working in PICUs. Not unexpectedly, the concept of dignified death was found to be a complex phenomenon involving aspects related to decisions made by the multidisciplinary team as well as those related to care of the child and the family. Knowledge of the concept`s dimensions can promote reflection on the part of healthcare professionals regarding the values and beliefs underlying their conduct in end-of-life situations. Our hope is that this study may contribute to theoretic and methodological development in the area of end-of-life care.

Friere`s Dialogic Concept Enables Family Health Program Teams to Incorporate Health Promotion

Objective The study analyzes the possibility of incorporating health promotion measures into the work processes of Family Health Program teams at a primary health care clinic in Brazil. Design and Sample We used the participatory research concept developed in 1968 by Freire. The study sample comprised the end-users of the health care system, together with 3 multidisciplinary teams. A total of 77 health care users and 55 health professionals participated in the study. Measures Culture circles composed of health care professionals, and users from different areas investigated generative topics, encoded/decoded topics, and engaged in critical probing for clarification. Topics affecting quality of life and health were heuristically evaluated. Results Although most topics were related to changing the focus of health care facilities, some were related to subsidizing community-based interventions, improving environmental strategies, individual skills, and public policies. Incorporating the novel health promotion measures and creating an expanded full-treatment clinic are important steps toward that goal. Conclusions Topics that can stimulate dialogue among the members of the culture circles include creating an environment of closer cultural contact, with repercussions for work processes, family health models, and general health models, as well as the inclusion of social aspects in the decision-making processes related to health issues that affect the living conditions of the population.

Innovation concept for measurement gross error detection and identification in power system state estimation

In this study, the innovation approach is used to estimate the measurement total error associated with power system state estimation. This is required because the power system equations are very much correlated with each other and as a consequence part of the measurements errors is masked. For that purpose an index, innovation index (II), which provides the quantity of new information a measurement contains is proposed. A critical measurement is the limit case of a measurement with low II, it has a zero II index and its error is totally masked. In other words, that measurement does not bring any innovation for the gross error test. Using the II of a measurement, the masked gross error by the state estimation is recovered; then the total gross error of that measurement is composed. Instead of the classical normalised measurement residual amplitude, the corresponding normalised composed measurement residual amplitude is used in the gross error detection and identification test, but with m degrees of freedom. The gross error processing turns out to be very simple to implement, requiring only few adaptations to the existing state estimation software. The IEEE-14 bus system is used to validate the proposed gross error detection and identification test.
