Modelling Breaks and Clusters in the Steady States of Macroeconomic Variables

Macroeconomists working with multivariate models typically face uncertainty over which (if any) of their variables have long run steady states which are subject to breaks. Furthermore, the nature of the break process is often unknown. In this paper, we draw on methods from the Bayesian clustering literature to develop an econometric methodology which: i) finds groups of variables which have the same number of breaks; and ii) determines the nature of the break process within each group. We present an application involving a five-variate steady-state VAR.

Expectations Traps and Coordination Failures with Discretionary Policymaking

Discretionary policymakers cannot manage private-sector expectations and cannot coordinate the actions of future policymakers. As a consequence, expectations traps and coordination failures can occur and multiple equilibria can arise. To utilize the explanatory power of models with multiple equilibria it is first necessary to understand how an economy arrives to a particular equilibrium. In this paper we employ notions of learnability and self-enforceability to motivate and identify equilibria of particular interest. Central among these criteria are whether the equilibrium is learnable by private agents and jointly learnable by private agents and the policymaker. We use two New Keynesian policy models to identify the strategic interactions that give rise to multiple equilibria and to illustrate our methods for identifying equilibria of interest. Importantly, unless the Pareto-preferred equilibrium is learnable by private agents, we find little reason to expect coordination on that equilibrium.

A forensic perspective of the AFL investigation into peptides: an antidoping investigation case study.

BACKGROUND: The World Anti-Doping Agency (WADA) is introducing enhancements to doping investigations in its 2015 Code, which include improved sharing of information between antidoping organisations (including sporting bodies) and enhanced accountability of athlete support staff. These additions will improve the control of links between sports doping and organised crime. In February 2013 the Australian Crime Commission released a report that linked several professional sporting codes, professional athletes with links to organised crime, performance enhancing drugs and illicit substances. Following this report the Australian Football League (AFL) partnered the Australian national antidoping organisation to investigate peptide use in Australian football. METHODS: This review compared the model proposed by Marclay, a hypothetical model for anti-doping investigations that proposed a forensic intelligence and analysis approach, to use the forensic capabilities of the AFL investigation to test the model's relevance to an actual case. RESULTS: The investigation uncovered the use of peptides used to enhance athlete performance. The AFL investigation found a high risk of doping where athlete support staff existed in teams with weak corporate governance controls. A further finding included the need for the investigation to provide a timely response in professional team sports that were sensitive to the competition timing. In the case of the AFL the team was sanctioned prior to the finals as an interim outcome for allowing the risk of use of performance-enhancing substances. Doping violation charges are still being considered. DISCUSSION: Antidoping strategies should include the investigation of corporate officers in team doping circumstances, the mandatory recording of all athlete substance use during competition and training phases, the wider sharing of forensic intelligence with non-sporting bodies particularly law enforcement and collaboration between antidoping and sporting organisations in doping investigations. CONCLUSIONS: The AFL investigation illustrated the importance of the 2015 WADA Code changes and highlighted the need for a systematic use of broad forensic intelligence activities in the investigation of doping violations.

Political-ethical skill development in nursing undergraduates

This research aimed to identify political-ethical skills developed in a training process compatible with the expected profile set by the National Curriculum Guidelines for the Undergraduate Nursing Degree. A case study was conducted with units represented by 32 former students from a particular religious teaching institution who already were in the job market. The content of the interviews was analyzed using the thematic analysis technique, which resulted in the following categories: "Political-ethical skills in the formative process" and "Political-ethical skills as a product of the educational process." From the former students’ perspective, these categories reinforced the social role of the nurse and the need for students to be reflective, understanding and participative in the transformation of society.

COMPETENCY-BASED TRAINING IN NURSING: LIMITS AND POSSIBILITIES

Objective To analyze the possibilities and limits of competency-based training in nursing. Method An integrative review of the literature on the subject was carried out, and an analysis was made of the results of a survey evaluating a nursing course based on areas of competency. A dialog was then established between the review and the results of the research. Results On the question of which theoretical type of competency the articles from the literature relate to, there is a predominance of the constructivist perspective, followed by the functionalist approach and the dialog-based approach. In the dialog between the literature and the research, limits and possibilities were observed in the development of a training by areas of competency. Conclusion The dialog-based approach to competency is the proposition that most approximates to the profile defined by the National Curriculum Guidelines for training in nursing, and this was also identified in the evaluation survey that was studied. However, it is found that there are aspects on better work is needed, such as: partnership between school and the workplace, the role of the teacher, the role of the student, and the process of evaluation.

Differences and similarities in rheumatology specialty training programmes across European countries.

OBJECTIVES: To analyse the similarities and discrepancies between the official rheumatology specialty training programmes across Europe. METHODS: A steering committee defined the main aspects of training to be assessed. In 2013, the rheumatology official training programmes were reviewed for each of the European League Against Rheumatism (EULAR) countries and two local physicians independently extracted data on the structure of training, included competencies and assessments performed. Analyses were descriptive. RESULTS: 41 of the 45 EULAR countries currently provide specialist training in rheumatology; in the remaining four rheumatologists are trained abroad. 36 (88%) had a single national curriculum, one country had two national curricula and four had only local or university-specific curricula. The mean length of training programmes in rheumatology was 45 (SD 19) months, ranging between 3 and 72 months. General internal medicine training was mandatory in 40 (98%) countries, and was performed prior to and/or during the rheumatology training programme (mean length: 33 (19) months). 33 (80%) countries had a formal final examination. CONCLUSIONS: Most European countries provide training in rheumatology, but the length, structure, contents and assessments of these training programmes are quite heterogeneous. In order to promote excellence in standards of care and to support physicians' mobility, a certain degree of harmonisation should be encouraged.

Química geral experimental: uma nova abordagem didática

This essay describes a new didactic approach, in according with the national curriculum guidelines for chemistry undergraduate courses in Brazil, employed during the one-semester course "Experimental General Chemistry" for chemistry undergraduate students at the Federal University of Piauí. The new approach has positively helped student's training by improving their reading skills and their understanding of scientific reports, by developing the use of electronic tools to search and to recover the required knowledge for their learning activities, and by improving their skills of understanding published texts and dealing with digital sources. At the same time the students are strongly stimulated to enter the research program for undergraduate students available at the University.

A graduação em química: um novo químico para uma nova era

The discussions sponsored by the Brazilian Chemical Society, over the past five years, intending to produce a chemistry agenda with perspectives and needs for the next decade for the country, have involved the national chemistry community and several related sectors of Brazilian society. Chemistry education has been the theme throughout these discussions. It is known that the low level of basic and secondary education and the recent increase in high school courses and institutions adversely affect the quality of undergraduate teaching. The recent national "Curriculum Guidelines" for Chemistry Courses, through their flexible approach, encourage the integral, interdisciplinary (non compartmentalized) and critical-reflexive training of professionals as citizens and as entrepreneurs. However, deficiencies are still recognized. The system of undergraduate course evaluation has identified the most fragile modalities of the courses and other indicators. Also, it has been verified that the Brazilian chemistry industry absorbs only minimally the highly qualified professionals, which is attributed to the fact that the Federal Council of Chemistry is vertically organized and does not recognize the graduate degrees as professional qualifications. In conclusion, the importance of the effective implantation of the national curriculum guidelines is apparent, among other aspects, highlighting courses whose didactical and pedagogical projects may offer a solid formation in Chemistry. However, at the same time the guidelines are comprehensive and general enough to enable the chemistry professionals to develop varied skills.

Du kan om du vill : lärares tankar om fostran till företagsamhet

The overall purpose of this dissertation is to better knowledge and understanding of enterprise education and investigate how such can be expressed in a school environment. The study’s research objective focuses on what teachers think and value about enterprise education and how they feel they are able to support students in their development towards an enterprising initiative. In the study’s theoretical background description, enterprise education, which was introduced into the Finnish national curriculum in 1994, is investigated outgoing from six so-named paths: linguistic, economic, educational-political, cultural, psychological, and the pedagogical, which is the main focus of the study. In the theoretical background, different characteristics have been identified; these are functional, social, and individual enterprise. The study’s empirical foundation consists of interviews with thirty teachers working at comprehensive and upper secondary schools. Two research efforts are combined: a phenomenographic and a phenomenological. In both efforts, a hermeneutic analysis takes place. Five principles that facilitate interpretation are presented and used: the indispensability of pre-understanding, the indispensability of the dimension of time, the indispensability of totality, the indispensability of negativism, and the indispensability of rationality. One study result is that teachers understand enterprise education as immanent, technical, and/or cooperative activity. The majority of teachers choose to emphasize that the purpose of activity is comprised of individual and social activity that is directed towards personal development, in contrast to functional enterprise, which is directed towards a technical form of activity and business-related, entrepreneurial knowledge. The question of how teachers understand the phenomenon is of significance for how they value it. The results also show that teachers’ abilities to reassess and change their manner are influenced by their knowledge/skills and awareness that they have of the interpretive possibilities that enterprise education manifests. In order to stimulate students to enterprising initiatives, teachers stress activity-promoting methods, authenticity, and an auspicious atmosphere in educational activities.

Musikaliska möten man minns : om musikundervisningen i årskurserna sju till nio som en arena för starka musikpplevelser

Earlier research has shown that strong experiences related to music (SEM) can occur in very different contexts and take on many different forms. Experiences like these seem significant and have among other things reportedly had an affect on the individual's continuing relationship towards music, which makes them interesting from a pedagogical point of view. Formal teaching situations, though, are under-represented in studies where people have been asked to describe strong experiences that they have had in connection with music. The purpose of my thesis is to investigate what SEM may mean to pupils and teachers in lower secondary school (grades 7-9), and to inquire more deeply into the potential "space" for such experiences within school music education. On a comprehensive level my ambition is to deepen the understanding for SEM as a possible element in pedagogical situations. Three empirical perspectives are employed: pupil-, teacher- and curriculum perspectives. The pupil perspective involved an analysis of written accounts of 166 fifteen-year-olds, describing own strong experiences. The teacher perspective involved studying 28 music teachers' conceptions of the purpose of teaching music in school as well as their understanding about strong music experiences in school context. Further, the teachers' descriptions of SEM that they have had themselves were analysed. The curriculum perspective is reflected through a study of how music experience was represented in 24 local and 2 national curriculum texts for music. Grounded in a phenomenological-hermeneutical perspective the material have been analyzed both qualitatively and quantitatively. The result points towards the fact that the music education in school has the potential to become an arena for SEM and that this can happen in relation to a multitude of activities and genres and take on many different expressions. Only one pupil referred to a musical encounter in the classroom environment; all other experiences that occurred inside the frame of school activity had taken place in other arenas (the school hall, public concert halls, and so on). However, more than 98 % of the descriptions concerned musical encounters in leisure time contexts. The significance of SEM is further clarified by narrative constructions. SEM as a conception does not occur on the curriculum level; however the analyze revealed a number of interesting "openings" which are illustrated. Even though all teachers displayed a fundamentally positive attitude towards the idea of regarding SEM as a feature of formal musical learning, it became clear that many teachers never had approached this theme from a pedagogical point of view before. Still, they proved to have an evident "familiarity" towards the phenomenon based on their own experiences of receptive and performative musical encounter. The possible space for strong musical experiences within school music education is specified through a detailed illustration of six specific themes derived from the reasoning of the teachers. Furthermore, this is described through a mapping of the potential experiencing zone, constructed from the teachers descriptions of educational aims.

Active teaching-learning methodologies: medical students' views of problem-based learning

The prevailing undergraduate medical training process still favors disconnection and professional distancing from social needs. The Brazilian Ministries of Education and Health, through the National Curriculum Guidelines, the Incentives Program for Changes in the Medical Curriculum (PROMED), and the National Program for Reorientation of Professional Training in Health (PRO-SAÚDE), promoted the stimulus for an effective connection between medical institutions and the Unified National Health System (SUS). In accordance to the new paradigm for medical training, the Centro Universitário Serra dos Órgãos (UNIFESO) established a teaching plan in 2005 using active methodologies, specifically problem-based learning (PBL). Research was conducted through semi-structured interviews with third-year undergraduate students at the UNIFESO Medical School. The results were categorized as proposed by Bardin's thematic analysis, with the purpose of verifying the students' impressions of the new curriculum. Active methodologies proved to be well-accepted by students, who defined them as exciting and inclusive of theory and practice in medical education.

Det planlagda och det som visar sig : klasslärarstuderandes syn på undervisning i teknisk slöjd

Sloyd as an activity concretizes man’s ability to, with the help of mind and body, reshape materials into objects and change her conditions for survival. The sloyd actor outside school works when the spirit moves her, while the pupil in school is expected to sloyd regardless of motivation. Subject teachers become experts on sloyd in educational settings, while the qualification requirements may set the class teachers’ voluntariness within parenthesis. All class teachers qualify to teach all core subjects of the national curriculum in Finland from preschool to grade six. The aim of the current thesis is to deepen the knowledge on how the science of sloyd education can support class teacher students’ future teaching in sloyd. In the empirical part of the study, Swedish-speaking Finnish class teacher students’ views on technical sloyd as one of their future subjects for teaching are examined. The class teacher’s qualifying skills in teaching technical sloyd are expected to take shape during only a few ECTS study points. The teacher students’ experience of the subject from the pupil’s perspective is supposed to move into a budding teacher subject. In a research-based teacher education, self-reflection and reflection as a dialogue are extended aided by research results. Intuitive thinking interplays with rational thinking during this time. The teacher student’s approach to make use of the autonomous free space in teaching is, in the current thesis, as considerations where the individual weighs the pros and cons in relation to various phenomena in sloyd and the school overall. The basis for an individual autonomy is shaped and is expected to interplay on the common arena of autonomy. In the exercise of their profession, the class teacher teaching sloyd is expected to oscillate between the sloyd educational practice and theory. The first step in this movement within the teacher education is the coverage of a selection of theories during the studies. The empirical part of the study is carried out at two separate occasions with directed open-ended interviews with fifteen class teacher students in the beginning and end of their first year of study. The data was analysed with a hermeneutic approach and a qualitatively oriented approach to content analysis. The results are mirrored against theory within the science of sloyd education. The results show that class teacher students have a versatile view of educational sloyd. The overall results overthrow parts of the researcher’s pre-understanding. The viewpoint of the students seems to broaden from a merely manual activity to seeing sloyd as an educational activity. In order for the results to gain significance in the teacher education of the future, a line of reasoning is conducted in order to recommend an extended dialogue and thirteen possible themes for enriching discussions are put forth as a result of the present study. The extended dialogue focuses on that teacher education should make conscious ventures to create opportunities for the students to take part in effective discussions on the subject of sloyd, complementing the existing dialogue between the teacher educator and the students. This thesis lends support to reflections on the following aspects of educational sloyd in these dialogues: the reasons for why the sloyd subject exists, the ambitions of the subject, the content and organization of the subject for students as well as for the teacher educators.

Sopeutumattomien oppilaiden tunne- ja itsesäätelytaitojen kehittyminen: Oppilaiden ja opettajien arvioita ja kokemuksia Aggression portaat -interventiosta

Tässä tutkimuksessa tarkastellaan sopeutumattomien erityisoppilaiden tunne- ja itsesäätelytaitojen kehittymistä Aggression portaat -interventio-ohjelman avulla kolmen vuoden tutkimusjakson aikana. Käsite sopeutumaton oppilas ei ole yksiselitteisesti määriteltävissä, mutta tässä tutkimuksessa sillä tarkoitetaan yleisopetussuunnitelman mukaan opiskelevaa oppilasta, joka käyttäytymiseen ja tunne-elämään liittyvien haasteidensa vuoksi on saanut siirron erityisopetuksen oppilaaksi ja saa enintään 10 oppilaan opetusryhmässä erityistä pedagogista tukea. Tutkimuksen yksi keskeinen tehtävä oli tutkia, onko tunne- ja itsesäätelytaitojen opettamisesta hyötyä sopeutumattomien oppilaiden tunteiden hallinnan ja käyttäytymisen itsesäätelyn kannalta. Tutkimuksen teoreettisena viitekehyksenä on Rose-Krasnorin (1997) malli yksilön sosioemotionaalisesta kompetenssista täydennettynä muiden tutkijoiden näkemyksillä. Sosioemotionaalinen kompetenssi on yläkäsite, johon kuuluvat alakäsitteinä tunne- ja itsesäätelytaidot, sosiokognitiiviset taidot ja sosiaaliset taidot. Lisäksi sosioemotionaaliseen kompetenssiin vaikuttavat kiintymyssuhteet ja osallisuus sekä tavoitteet vuorovaikutuksessa ja konteksti. Tässä tutkimuksessa keskitytään tunne- ja itsesäätelytaitoihin. Interventioryhmän (N=36) muodostivat Varsinais-Suomen alueella opiskelevat sopeutumattomien oppilaiden erityiskoulun 8-13-vuotiaat oppilaat, joille opetettiin tunne- ja itsesäätelytaitoja Aggression portaat -opetusmateriaaliin (Cacciatore 2007) pohjautuvan intervention avulla. Kontrolliryhmän (N=26) oppilaat olivat interventioryhmän oppilaiden ikäisiä ja he opiskelivat Varsinais-Suomen alueen kouluissa pienluokissa myös käyttäytymiseen ja tunne-elämään liittyvien haasteidensa vuoksi. Kontrolliryhmän oppilaat eivät saaneet tutkimusjakson aikana interventio-ohjelman mukaista opetusta. Interventioryhmän oppilaat kävivät erityiskoulua, jossa kaikilla oppilailla oli sopeutumisongelmia ja kontrolliryhmän oppilaat opiskelivat yleisopetuksen koulujen yhteydessä olevilla sopeutumattomien oppilaiden pienluokilla. Tutkimusaineisto on kerätty vuosina 2010-2012. Tutkimusmetodeina olivat sekä oppilaille että opettajille laaditut Webropol-alustaiset kyselyt ja oppilaiden kirjoittamat väkivalta-aiheiset tekstit. Tutkimus- ja kontrolliryhmän oppilaille pidettiin ”Tunteiden hallinta ja käyttäytyminen”- kyselyn avulla alkumittaus syksyllä 2009 ja mittaus toistettiin keväällä 2010, 2011 ja 2012. Kyselyiden avulla selvitettiin, miten oppilaiden tunteiden kokeminen ja ilmaiseminen sekä tunteiden hallinta ja käyttäytymisen itsesäätely muuttuivat tutkimusjakson aikana. Kyselyssä kartoitettiin myös oppilaiden kokemuksia kiusaamisena ilmenevästä väkivallasta. Aineistolähtöisen sisällönanalyysin avulla selvitettiin oppilaiden kirjoitelmista heidän ajatuksiaan ja näkemyksiään väkivallasta ja ehdotuksia keinoista väkivallan vähentämiseksi. Keväällä 2012 interventioryhmän oppilaille ja opettajille laadittujen erillisten kyselyiden avulla selvitettiin sekä oppilaiden että opettajien arvioita ja kokemuksia oppilaiden tunne- ja itsesäätelytaitojen muutoksesta interventio-ohjelman avulla. Lisäksi oppilaat ja opettajat arvioivat pidettyjen tunnetaitotuntien hyödyllisyyttä oppilaille. Interventioryhmän opettajat arvioivat myös Aggression portaat -interventiomateriaalin käyttökelpoisuutta. Vuoden 2014 Perusopetuksen opetussuunnitelman perusteissa esitetyt velvoitteet opettaa kouluissa oppilaille tunne- ja vuorovaikutustaitoja edellyttävät tietoa konkreettisista käytänteistä ja tutkimusperustaisista interventio-ohjelmista. Tämän tutkimuksen tulokset osoittavat, että interventioryhmän muodostaneet sopeutumattomat oppilaat hyötyivät Aggression portaat -interventiosta. Heidän tunne- ja itsesäätelytaidoissaan tapahtui myönteistä kehitystä etenkin myönteisten tunnekokemusten lisääntymisen ja toisiin kohdistuneen fyysisen väkivallan vähenemisen osalta. Myös suhtautuminen väkivaltapelien ikärajoihin oli merkittävästi myönteisempää kuin kontrolliryhmän oppilailla, joilla kielteinen asenne lisääntyi selvästi tutkimusjakson aikana. Lisäksi interventioryhmän oppilailla oli keinoja itsensä rentouttamiseksi, päinvastoin kuin kontrolliryhmän oppilailla, joilla keinottomuuden kokemus jopa lisääntyi. Interventioryhmän oppilaat suhtautuivat hyvin kielteisesti toisen yllyttämiseen väkivaltaiseen tekoon ja kirjoittivat enemmän ajatuksiaan väkivallasta tuoden esille runsaasti ehdotuksia keinoista väkivallan vähentämiseksi. Myös oppilaat ja opettajat kokivat interventio-ohjelman oppilaiden kehityksen kannalta hyödylliseksi ja opettajat myös interventiomateriaalin käyttökelpoiseksi.

In search of good relationships to music : understanding aspiration and challenge in developing music school teacher practices

This study focuses on teacher practices in publicly funded music schools in Finland. As views on the aims of music education change and broaden, music schools across Europe share the challenge of developing their activities in response. In public and scholarly debate, there have been calls for increased diversity of contents and concepts of teaching. In Finland, the official national curriculum for state-funded music schools builds on the ideal that teaching and learning should create conditions which promote ‘a good relationship to music’. The meaning of this concept has been deliberately left open in order to leave room for dialogue, flexibility, and teacher autonomy. Since what is meant by ‘good’ is not defined in advance, the notion of ‘improving’ practices is also open to discussion. The purpose of the study is to examine these issues from teachers’ point of view by asking what music school teachers aim to accomplish as they develop their practices. Methodologically, the study introduces a suggestion for building empirical research on Alperson’s ‘robust’ praxial approach to music education, a philosophical theory which is strongly committed to practitioner perspectives and musical diversity. A systematic method for analysing music education practices, interpretive practice analysis, is elaborated with support from interpretive research methods originally used in policy analysis. In addition, the research design shows how reflecting conversations (a collaborative approach well-known in Nordic social work) can be fruitfully applied in interpretive research and combined with teacher inquiry. Data have been generated in a collaborative project involving five experienced music school teachers and the researcher. The empirical material includes transcripts from group conversations, data from teacher inquiry conducted within the project, and transcripts from follow-up interviews. The teachers’ aspirations can be understood as strivings to reinforce the connection between musical practices and various forms of human flourishing such that music and flourishing can sustain each other. Examples from their practices show how the word ‘good’ receives its meaning in context. Central among the teachers’ concerns is their hope that students develop a free and sustainable interest in music, often described as inspiration. I propose that ‘good relationships to music’ and ‘inspiration’ can be understood as philosophical mediators which support the transition from an indeterminate ‘interest in music’ towards specific ways in which music can become a (co-)constitutive part of living well in each person’s particular circumstances. Different musical practices emphasise different aspects of what is considered important in music and in human life. Music school teachers consciously balance between a variety of such values. They also make efforts to resist pressure which might threaten the goods they think are most important. Such goods include joy, participation, perseverance, solid musical skills related to specific practices, and a strong sense of vitality. The insights from this study suggest that when teachers are able to create inspiration, they seem to do so by performing complex work which combines musical and educational aims and makes general positive contributions to their students’ lives. Ensuring that teaching and learning in music schools remain as constructive and meaningful as possible for both students and teachers is a demanding task. The study indicates that collaborative, reflective and interdisciplinary work may be helpful as support for development processes on both individual and collective levels of music school teacher practices.
