Using music as a signal for biofeedback

Studies on the potential benefits of conveying biofeedback stimulus using a musical signal have appeared in recent years with the intent of harnessing the strong effects that music listening may have on subjects. While results are encouraging, the fundamental question has yet to be addressed, of how combined music and biofeedback compares to the already established use of either of these elements separately. This experiment, involving young adults (N = 24), compared the effectiveness at modulating participants' states of physiological arousal of each of the following conditions: A) listening to pre-recorded music, B) sonification biofeedback of the heart rate, and C) an algorithmically modulated musical feedback signal conveying the subject's heart rate. Our hypothesis was that each of the conditions (A), (B) and (C) would differ from the other two in the extent to which it enables participants to increase and decrease their state of physiological arousal, with (C) being more effective than (B), and both more than (A). Several physiological measures and qualitative responses were recorded and analyzed. Results show that using musical biofeedback allowed participants to modulate their state of physiological arousal at least equally well as sonification biofeedback, and much better than just listening to music, as reflected in their heart rate measurements, controlling for respiration-rate. Our findings indicate that the known effects of music in modulating arousal can therefore be beneficially harnessed when designing a biofeedback protocol.

Describing and Analyzing Information Technology through Total Quality Management and Process Management: Case Stora Enso Newsprint

Laatu on osaltaan vahvistamassa asemaansa liike-elämässä yritysten kilpaillessa kansainvälisillä markkinoilla niin hinnalla kuin laadulla. Tämä suuntaus on synnyttänyt useita laatuohjelmia, joita käytetään ahkerasti yritysten kokonais- valtaisen laatujohtamisen (TQM) toteuttamisessa. Laatujohtaminen kattaa yrityksen kaikki toiminnot ja luo vaatimuksia myös yrityksen tukitoimintojen kehittämiselle ja parantamiselle. Näihin lukeutuu myös tämän tutkimuksen kohde tietohallinto (IT). Tutkielman tavoitteena oli kuvata IT prosessin nykytila. Tutkielmassa laadittu prosessikuvaus pohjautuu prosessijohtamisen teoriaan ja kohdeyrityksen käyttämään laatupalkinto kriteeristöön. Tutkimusmenetelmänä prosessin nykytilan selvittämiseksi käytettiin teemahaastattelutta. Prosessin nykytilan ja sille asetettujen vaatimusten selvittämiseksi haastateltiin IT prosessin asiakkaita. Prosessianalyysi, tärkeimpien ala-prosessien tunnistaminen ja parannusalueiden löytäminen ovat tämän tutkielman keskeisemmät tulokset. Tutkielma painottui IT prosessin heikkouksien ja parannuskohteiden etsimiseen jatkuvan kehittämisen pohjaksi, ei niinkään prosessin radikaaliin uudistamiseen. Tutkielmassa esitellään TQM:n periaatteet, laatutyökaluja sekä prosessijohtamisen terminologia, periaatteet ja sen systemaattinen toteutus. Työ antaa myös kuvan siitä, miten TQM ja prosessijohtaminen niveltyvät yrityksen laatutyössä.

En uno de los capítulos de Los Simpson, la pequeña Lisa compra, emocionada, la última versión de Stacy Malibú (el equivalente a nuestra Barbie). La novedad consiste en que después de 50 años de existencia, la muñeca habla. Pero para consternación de Lisa, el repertorio de frases es de lo más indignante: "Me encantaría que en la escuela enseñaran a ir de compras", "¡Vamos a hornear unas galletas para los chicos!" o "No me preguntes: sólo soy una chica (risita vacua)". Obviamente, la comprometida y concienciada Lisa no puede quedarse de brazos cruzados y pide a su madre que la lleve a la fábrica de Stacy Malibú para presentar sus quejas. La conversación entre ambas es enormemente reveladora: aunque Marge apoya a su hija e insiste en que siempre defienda sus ideas, considera que quizás está yendo más allá de lo razonable en su denuncia de que toda una generación de niñas se comportará como Stacy Malibú y la tomará como modelo y, finalmente, concluye en tono conciliador: "Yo tuve una Stacy Malibú de pequeña y no me ha pasado nada.¡Vamos a olvidarnos de estos problemas con un gran bol de helado de fresa!". La respuesta de Lisa no deja lugar a dudas; poniendo en funcionamiento a la muñeca y situándola frente a su madre, oímos a Stacy diciendo: "¡Vamos a olvidarnos de estos problemas con un gran bol de helado de fresa!". Huelgan los comentarios.

Understanding academics' popular science publishing : institution culture and management style effects

Most universities and higher education systems have formally taken up a third mission, which involves various public outreach and engagement activities. Little is known regarding how higher education institutions' organisations interact with academic's level of public outreach. This article examines to which extent the perceptions academics have of their institutions' culture and management style, as well as some of their own individual and statutory characteristics interact with their level of public outreach. Using the Academic Profession in Europe comparative and quantitative research database, this article focuses on two countries on the extremities of the spectrum - Switzerland and the United Kingdom.

Comparison of Four Sections for Analyzing Running Mechanics Alterations During Repeated Treadmill Sprints.

We compared different approaches to analyze running mechanics alterations during repeated treadmill sprints. Thirteen active male athletes performed five 5-second sprints with 25 seconds of recovery on an instrumented treadmill. This approach allowed continuous measurement of running kinetics/kinematics and calculation of vertical and leg stiffness variables that were subsequently averaged over 3 distinct sections of the 5-second sprint (steps 2-5, 7-10, and 12-15) and for all steps (steps 2-15). Independently from the analyzed section, propulsive power and step frequency decreased with fatigue, while contact time and step length increased (P < .05). Except for step frequency, all mechanical variables varied (P < .05) across sprint sections. The only parameters that highly depend on running velocity (propulsive power and vertical stiffness) showed a significant interaction (P < .05) between the analyzed sections, with smaller magnitude of fatigue-induced change observed for steps 2-5. Considering all steps or only a few steps during early, middle, or late phases of 5-second sprints provides similar mechanical outcomes during repeated treadmill sprinting, although acceleration induces noticeable differences between the sections studied. Furthermore, quantifying mechanical alterations from the early acceleration phase may not be readily detectable, and is not recommended.

Traditional cockney and popular London speech

This paper gives a full description of the phonetics and phonology of Traditional Cockney and Popular London speech, treating these varieties as constituting a continuum rather than two separate dialects. Exemplification of the vowels, diphthongs and consonants is provided, both in isolate words and in connected speech, along with their range of variation. The frequencies of the vowels have been charted on the basis of the pronunciation of three elderly male speakers. Regarding the consonants, there are detailed observations on the features typically associated with the linguistic varieties examined: strong aspiration of unvoiced plosives, glottalization, H-dropping, L-vocalization and TH-fronting. A section on prosody provides coverage of lexical stress, rhythm and intonation. The paper takes into account up-to-date research on these phenomena, but does not deal with the most recent vowel shifts, some of which form part of Multi-cultural London English.

How diverse is Cologne Carnival? How migrants appropriate popular art spaces

The present article contributes to the ongoing academic debate on migrants' appropriation of artistic and political spaces in Germany. Cologne, one of the largest cities in Germany, is an interesting example of the tension between political discourse centred around multiculturalism and cultural segregation processes. The 'no fool is illegal' carnival organised by asylum seekers shows their capacity to act, as they reinvent an old local tradition by reinterpreting medieval rituals. Today, different groups and associations appropriate this festive art space: migrants, gays and lesbians, feminists and far-left groups either organise their own parties or take part in the official parties and parades as separate groups. As a result, the celebration of diversity figures on the local political agenda and becomes part of the official carnival festivities. This leads to a blurring of boundaries, whereby mainstream popular culture becomes more and more influenced by multicultural elements.

A propòsit d'una cançó popular recollida per Jacint Verdaguer i enviada al seu amic Marià Aguiló

«Comiat de Vic» forma part del recull de cançons populars que Jacint Verdaguer va enviar al seu amic i erudit mallorquí Marià Aguiló. La lletra de la cançó traça un itinerari a través de la ciutat que va fent menció dels edificis religiosos que es troben durant el trajecte. L’emoció acumulada i el dolor de la partença indiquen que probablement es tracta del comiat definitiu d’un condemnat a mort.
