Causality and endogeneity: Problems and solutions

Most leadership and management researchers ignore one key design and estimation problem rendering parameter estimates uninterpretable: Endogeneity. We discuss the problem of endogeneity in depth and explain conditions that engender it using examples grounded in the leadership literature. We show how consistent causal estimates can be derived from the randomized experiment, where endogeneity is eliminated by experimental design. We then review the reasons why estimates may become biased (i.e., inconsistent) in non-experimental designs and present a number of useful remedies for examining causal relations with non-experimental data. We write in intuitive terms using nontechnical language to make this chapter accessible to a large audience.

Is the PHY layer dead?

This article originates from a panel with the above title, held at IEEE VTC Spring 2009, in which the authors took part. The enthusiastic response it received prompted us to discuss for a wider audience whether research at the physical layer (PHY) is still relevant to the field of wireless communications. Using cellular systems as the axis of our exposition, we exemplify areas where PHY research has indeed hit a performance wall and where any improvements are expected to be marginal. We then discuss whether the research directions taken in the past have always been the right choice and how lessons learned could influence future policy decisions. Several of the raised issues are subsequently discussed in greater details, e.g., the growing divergence between academia and industry. With this argumentation at hand, we identify areas that are either under-developed or likely to be of impact in coming years - hence corroborating the relevance and importance of PHY research.

Intuitiosta esitykseen : Lear-prosessi itsereflektion ja katsojapalautteen valossa

My final project presents the directing process of my experimental production based on King Lear by William Shakespeare. I describe the process from the first visions of the beginning to the completed performance and finally the feedback from the audience. I concentrate on the special qualities of the production, such as interaction, small and moveable audience, cinematic qualities, polyphonic dramaturgy, and use of the video. The Project is divided into six parts. The first part introduces the project as a whole. The second part concentrates on the process before the beginning of the rehearsals. The third part focuses on the rehearsals and co-operation with the actors, whereas the fourth part deals with the performance and its special qualities. Following this, in the fifth part I study the interaction of the performance with the help of the audience feedback. In the final part conclusions are drawn. The focus of this work is the use of intuition even as a starting point of the theatre directing process. My conclusions drawn from the description of the process suggest that the starting point of the theatre production may be an intuitive vision as well as some conscious subject or message.

Rohkeutta henkilöiden käsittelyyn : katsojatutkimus 45 minuuttia -ajankohtaisohjelman henkilökuvajutuista

The present thesis deals with the reception of the celebrity profiles of the MTV3 news current affairs program "45 minuuttia". The target group of the research consists of young adults between the ages from 25 to 34 living in the Helsinki metropolitan area. The research is qualitative and it studies the target group's opinions of the program profiles by the means of a survey and a group interview. In the group interview, the interviewees were also presented sample clips of the program. The results of the survey were analyzed mainly quantitatively. The purpose of the survey results was to map the viewing habits of the target group. In analyzing the results of the group, the interview methods of feedback research and cultural audience research were used. The current thesis was a commissioned research, the purpose of which was to study how interested the young adults are in the program. In addition, the aim was also to find out possible new trends and approaches for the producer of the program. In contrary to the expectations, the reason for the low interest in the profiles seemed to be due to the approach taken to the topics, e.g. the profiled person. By the approach I mean how the person is visually presented or how the person is verbally described. Many people presented in the profiles were regarded as interesting, but at the same time, the way the stories were told was hoped to be more versatile. In addition, a more contemporary visual approach was hoped for. The results also verified the claim that the young adults in general are not interested in the current affair programmes. In addition, these results suggested that in order to obtain more precise information of the viewing preferences of the audience, a more thorough study should be conducted.

Lisäase yleisöjahtiin : yleisötyön mahdollisuudet Kettupäivät-elokuvafestivaalin yleisöpohjan kehittämisessä

Työskentelin vuonna 2005 kotimaisen lyhyt- ja dokumenttielokuvan festivaalilla Kettupäivillä tiedottajana. Festivaalia järjestävän Suomen elokuvakontakti ry:n toiminnan tavoitteina on mm. edistää elokuvantekijöiden ja yleisön välisiä kontakteja ja lisätä kiinnostusta elokuvan eri muotoihin. Tavoitteensa saavuttamiseksi se järjestää vuosittain Kettupäiviä. Työskennellessäni Kettupäivillä huomasin, että suuri yleisö ei ole ottanut tapahtumaa Suomen elokuvakontakti ry:n tavoitteen mukaisesti omakseen. Festivaali käyttää yleisön tavoittamiseen perinteisiä keinoja eli tiedottamista ja markkinointia. Tiedotuksen ja markkinoinnin ohella yleisön tavoittamiskeinoksi on Suomessakin nousemassa yleisötyö. Yleisötyötä voidaan pitää keinona kulttuuritapahtuman helpompaan saavuttamiseen. Kulttuuritapahtuma on saavutettava silloin, kun erilaiset yleisöt voivat osallistua siihen mahdollisimman helposti ja esteettömästi. Kulttuuritapahtuman saavutettavuutta voidaan parantaa poistamalla osallistumisen esteitä. Esteet voivat olla fyysisiä, aisteihin liittyviä, taloudellisia, asenteellisia/henkisiä, tiedollisia tai tiedottamiseen liittyviä tai päätöksen teon puutteellisuudesta johtuvia. Yleisötyö toimii lähinnä asenteellisten ja tiedollisten esteiden poistamisen keinona. Työn tavoitteena on löytää konkreettisia esimerkkejä Kettupäivien yleisötyöhön ja sitä kautta laajemman yleisön tavoittamiseen festivaalille. Tutkin yleisötyötä kolmen erilaisen helsinkiläisen kulttuuriorganisaation tekemän yleisötyön kautta. Haastattelut tein vuosien 2005 ja 2006 vaihteessa, jonka jälkeen kirjoitin työn seuraavan vuoden aikana. Yleisötyön merkitys markkinoinnin ja tiedotuksen ohella kulttuurituotteen ulkoisen viestinnän ja yleisön saavuttamisen kannalta on oleellinen etenkin pienissä tai muulla tapaa marginaalissa toimivissa kulttuuriorganisaatioissa. Tärkeää pienen tai keskisuuren taideorganisaation yleisötyössä on resurssien laskeminen siten, ettei yleisötyö syö voimavaroja päätoimintamuodosta, mutta että yleisötyöllä on oma vahva merkityksensä yleisöjen liikuttamisessa ja kulttuurituotteen tunnettuuden lisäämisessä.

Identifying and Implementing Effective Training for Hispanic Craft Workers, American Supervisors, and DOT Inspectors: Phase III of the Hispanic Workforce Research Project, May 2006

The number of Hispanic workers in the U.S. construction industry has been steadily increasing, and language and cultural barriers have sometimes arisen on the jobsite. Due in part to these barriers, the number of fatalities among Hispanics at construction sites in 2001 jumped 24%, while construction fatalities overall dropped 3%. This study, which constitutes Phase III of the Hispanic Workforce Research Project, addresses these language and cultural barriers by investigating the most effective way to deliver training material developed in Phases I and II to Hispanic workers, American supervisors, and department of transportation (DOT) inspectors. The research methodology consisted of assessing the needs and interests of potential and current course participants in terms of exploring innovative ways to deliver the training. The training courses were then adapted and delivered to fit the specific needs of each audience. During Phase III of this project, the research team delivered the courses described in the Phase I and II reports to eight highway construction companies and two DOT groups. The courses developed in Phases I and II consist of four construction-focused language training courses that can be part of an effective training program to facilitate integration among U.S. and Hispanic workers, increase productivity and motivation at the jobsite, and decrease the existing high mortality rate for Hispanic workers. Moreover, the research team developed a course for the construction season called Toolbox Integration Course for Hispanic workers and American supervisors (TICHA), which consists of nine 45-minute modules delivered to one construction company over 11 weeks in the summer of 2005.

Proyecto Delta : interrelación entre intérprete, obra y público en la música contemporánea

Proyecto Delta es una iniciativa escenográfica de un programa de concierto específico constituido con obras de música contemporánea. La propuesta se lleva a cabo gracias a un fundamento teórico que incluye reflexiones en torno a las figuras comprometidas en el acto musical escénico: intérprete, obra y público. En esta digresión sus funciones son objeto de un desfiguramiento, fomentando la capacidad creativa del intérprete como director artístico. El concierto se convierte, de este modo, en un producto acabado. En particular, el Proyecto Delta se construye sobre el diálogo entre lo sonoro y lo visual, lo audible y lo visible: la música y el espacio.

Cross-cultural adaptation of the Caregiver Reaction Assessment for use in Brazil with informal caregivers of the elderly

This study aimed to carry out the cross-cultural adaptation of the Caregiver Reaction Assessment CRA for use in Brazil with informal caregivers of dependent elderly METHOD A methodological study, of five steps: initial translation, synthesis of translations, retro-translation, evaluation by a judge committee and a pre-test, with 30 informal caregivers of older persons in Fortaleza, Brazil. Content validity was assessed by five experts in gerontology and geriatrics. The cross-cultural adaptation was rigorously conducted, allowing for inferring credibility. RESULTS The Brazilian version of the CRA had a simple and fast application (ten minutes), easily understood by the target audience. It is semantically, idiomatically, experimentally and conceptually equivalent to the original version, with valid content to assess the burden of informal caregivers for the elderly (Content Validity Index = 0.883). CONCLUSION It is necessary that other psychometric properties of validity and reliability are tested before using in care practice and research.

Chopin & Leopardi : dues sensibilitats bessones

Aquest treball vol estudiar les relacions que s'estableixen entre dos artistes d'un mateix període estètic: Frédéric Chopin i Giacomo Leopardi. Ho fa analitzant 7 parelles de música i poesia, analitzades per descobrir què és allò que les uneix. Després d'una reflexió al voltant de l'art, el treball reflexiona sobre què aporta a l'estudi d'un període artístic, d'unes determinades obres o a l'escolta d'un concert, la combinació de dues o més disciplines artístiques. Chopin & Leopardi: dues sensibilitats bessones, doncs, que acaben connectant també amb nosaltres, descobrint en l'art l'expressió de quelcom universal que uneix artista, intèrpret i públic.

Cardio respiratory activity in high-anxious vs. low-anxious professional music students before and during performance

Questionnaire studies indicate that high-anxious musicians may suffer from hyperventilation symptoms before and/or during performance. Reported symptoms include amongst others shortness of breath, fast or deep breathing, dizziness and thumping heart. However, no study has yet tested if these self-reported symptoms reflect actual cardio respiratory changes. Disturbances in breathing patterns and hyperventilation may contribute to the often observed poorer performance of anxious musicians under stressful performance situations. The main goal of this study is to determine if music performance anxiety is manifest physiologically in specific correlates of cardio respiratory activity. We studied 74 professional music students divided into two groups (i.e. high-anxious and lowanxious) based on their self-reported performance anxiety in three distinct situations: baseline, private performance (without audience), public performance (with audience). We measured a) breathing patterns, end-tidal carbon dioxide (EtCO2, a good non-invasive estimator for hyperventilation), ECG and b) self-perceived emotions and self-perceived physiological activation. The poster will concentrate on the preliminary results of this study. The focus will be a) on differences between high-anxious and low-anxious musicians regarding breaths per minute and heart rate and b) on the response coherence between self-perceived palpitations and actual heart rate.

Building adaptive capacity and resilience to climate change in the water sector in Cape Verde

Purpose of the evaluation This is a scheduled standard mid-term evaluation (MTR) of a UNDP implemented GEF LDCF co-financed project. It is conducted by a team of an international and a national independent evaluator. The objective of the MTR, as set out in the Terms of Reference (TORs; Annex 1), is to provide an independent analysis of the progress of the project so far. The MTR aims to:  identify potential project design problems,  assess progress towards the achievement of the project objective and outcomes,  identify and document lessons learned (including lessons that might improve design and implementation of other projects, including UNDP-GEF supported projects), and  make recommendations regarding specific actions that should be taken to improve the project. The MTR is intended to assess signs of project success or failure and identify the necessary changes to be made. The project commenced its implementation in the first half of 2010 with the recruitment of project staff. According to the updated project plan, it is due to close in July 201410 with operations scaling down in December 2013 due to funding limits. Because of a slow implementation start, the mid-term evaluation was delayed to July 201311 The intended target audience of the evaluation are:  The project team and decision makers in the INGRH  The GEF and UNFCCC Operational Focal Points  The project partners and beneficiaries  UNDP in Cape Verde as well as the regional and headquarter (HQ) office levels  The GEF Secretariat.

Going Public in the European Union: Action Repertoires of Western European Collective Political Actors

As a result of the Europeanization of politics and the increasing role of the public sphere, political actors in Western Europe are currently facing a double strategic challenge. Based on data from seven West European countries and the European Union, the authors analyze how state actors, political parties, interest groups, and social movement organizations cope with this double challenge at both the national and the supranational level. Results indicate that the classic repertoire of inside strategies at the national level is still the most typical for all actors, but media-related strategies are also prominent at the national level. The Europeanization of repertoires is mainly determined by institutional factors and by the actors' power, whereas the public arena plays an equally important role for all types of actors, in all countries and at both the national and the EU level.

Processus et fonctions psychiques de l'écriture : de la création littéraire au groupe à médiation

Ce travail porte sur l'étude des processus et fonctions psychiques de la création littéraire et de l'écriture dans une perspective psychanalytique, à partir d'une méthodologie de recherche qualitative exploratoire. Un premier volet de la recherche s'attache à étudier les processus et fonctions psychiques dans la création littéraire à partir de six entretiens semi-structurés avec des écrivains romands publiés. Les entretiens sont analysés en profondeur à partir de la méthodologie qualitative Interpretative Phenomenological Analysis (Smith, Flowers & Larkin, 2009). Un second volet de la recherche étudie les processus et fonctions psychiques de l'écriture dans un atelier de groupe à médiation écriture prenant place dans un Centre de Jour pour adultes, à partir de l'élaboration de deux cas. L'articulation des analyses de ces expériences d'écriture dans les deux contextes étudiés permet de mettre en évidence des enjeux de continuité/discontinuité dans le passage du premier mouvement créateur de l'écriture - le « miroir-papier » - vers le mouvement de la publication/lecture - le « miroir-lecteur ». Ces enjeux de partage invitent à penser le travail créateur de l'écriture à partir de la notion de « Moi- peau » (Anzieu, 1995) et à préciser cinq fonctions psychiques de l'écriture : transformation ; protection ; échange ; réassurance narcissique ; partage. Un accent particulier est porté sur la fonction de protection, dans la tension qu'elle entretient avec celle de transformation, au travers de la mise en évidence de six formes d'enveloppes d'écriture protectrice. Finalement, les analyses mettent en évidence la manière dont cette tension entre un investissement défensif de l'écriture et un investissement de transformation se déploie par des voies singulières en vue d'une tentative de résolution du conflit subjectif interne entre les exigences du « public intérieur » (De M'Uzan, 1964) et la rencontre avec l'objet réel. Ces pistes d'analyses permettent de préciser les modalités de contribution de l'écriture aux processus de symbolisation et d'enrichir la pratique du champ des médiations thérapeutiques de repères d'appréciation clinique. - Based on an exploratory qualitative research methodology, this work focuses on the psychical processes and functions of literary creation and writing from a psychoanalytic perspective. The first part of the research investigates psychical processes and functions in creative writing through the analysis of six semi-structured interviews with published Swiss writers. The interviews are analyzed according to the exploratory qualitative methodology Interpretative Phenomenological Analysis (Smith, Flowers & Larkin, 2009). The second area of research examines the processes of writing in the context of an art-therapy writing group that took place in an adult day center. The observations lead to the elaboration of two case studies. The joint analysis of these writing experiences highlights issues of continuity/discontinuity in passing from the first creative writing movement - the « mirror-paper » - to the final publication/reading of the work - the «mirror-reader». These issues enable us to understand the creative writing processes from the concept of the « skin-ego » (Anzieu, 1995). Five functions of writing are proposed: transformation, protection, exchange, narcissistic reassurance, and sharing. An emphasis on the tension between the protection and the transformation functions is highlighted through the identification of six forms of protective writing psychical envelopes. Finally, the analysis shows how this tension between a defensive and a transformative investment in writing takes place in an attempt to resolve the internal conflict between the « inner audience » (De M'Uzan, 1964) and the encounter with the real object. This study clarifies the way creative writing can contribute to symbolization and can enrich clinical assessment in the field of art-therapy.
