Voice Transformations for Extreme Vocal Effects

Extreme Vocal Effects (EVE) in music are so recent that few studies have been carried out about how they are physiologically produced and whether they are harmful or not for the human voice.Voice Transformations in real-time are possible nowadays thanks to new technologies and voice processing algorithms. This Master's Thesis pretends to define and classify these new singing techniques and to create a mapping between the physiological aspect of each EVE to its relative spectrumvariations.Voice Transformation Models based on these mappings are proposed and discussed for each one of these EVEs. We also discuss different transformation methods and strategies in order to obtain better results.A subjective evaluation of the results of the transformations is also presented and discussed along with further work, improvements, and working lines on this field.

SUMMARY: Background Probiotics have been associated with prevention and improvement of symptoms in atopic diseases such as atopic dermatitis. However, few studies exist that document their efficacy for upper airways allergies such as allergic rhinitis. Objective To investigate the effect of short-term oral administration of Lactobacillus paracasei ST11 on a nasal provocation test (NPT) with grass pollen. Methods Thirty-one adult volunteers with allergic rhinitis were enrolled in a randomized, double-blind, placebo-controlled study, based on two 4-week cross-over periods of product consumption (ST11-fermented milk vs. placebo), separated by a wash-out period of 6-8 weeks. Objective and subjective clinical parameters of NPT as well as systemic and nasal immunological parameters were compared between the two treatment periods (registration number: NCT 011 50 253). Results Subjects that received ST11-fermented milk had lower nasal congestion than subjects under placebo (visual analogical scale; P<0.05). Nasal pruritus followed the same trend. However, no significant change in combined nasal reaction threshold was observed between the two periods. IL-5 secretion by peripheral blood mononuclear cells and serum allergen-specific IgG4 were significantly lower in ST11-fermented milk group compared to placebo group. IL-8 and IL-10 secretion followed the same trend. Conclusion and Clinical Relevance Short-term treatment with ST11-fermented milk before NPT significantly improved a clinical marker of NPT (subjective nasal congestion) and down-regulated systemic immune markers (IL-5 from peripheral blood mononuclear cells and serum IgG4). These data strongly suggest that probiotics may down modulate key parameters of allergic rhinitis and warrant future evaluation in seasonal trials.

Carvedilol inhibits the cardiostimulant and thermogenic effects of MDMA in humans.

BACKGROUND AND PURPOSE: The use of ± 3,4-methylenedioxymethamphetamine (MDMA, 'ecstasy') is associated with cardiovascular complications and hyperthermia. EXPERIMENTAL APPROACH: We assessed the effects of the α(1) - and β-adrenoceptor antagonist carvedilol on the cardiostimulant, thermogenic and subjective responses to MDMA in 16 healthy subjects. Carvedilol (50 mg) or placebo was administered 1 h before MDMA (125 mg) or placebo using a randomized, double-blind, placebo-controlled, four-period crossover design. KEY RESULTS Carvedilol reduced MDMA-induced elevations in blood pressure, heart rate and body temperature. Carvedilol did not affect the subjective effects of MDMA including MDMA-induced good drug effects, drug high, drug liking, stimulation or adverse effects. Carvedilol did not alter the plasma exposure to MDMA. CONCLUSIONS AND IMPLICATIONS: α(1) - and β-Adrenoceptors contribute to the cardiostimulant and thermogenic effects of MDMA in humans but not to its psychotropic effects. Carvedilol could be useful in the treatment of cardiovascular and hyperthermic complications associated with ecstasy use.

Voiko totuutta tavoittaa? : direct cinema -tyylisuunnan käyttö dokumenttielokuvassa

The subject of this study is the use of direct cinema style in documentary film. The main purpose of this thesis was to the research the ways in which direct cinema style attempts to show and achieve truth in documentary films. The following questions were posed: Is it possible to depict reality in a documentary film; how does the choice of using this style affect the final documentary? The essential purpose of this study was to try to see whether the direct cinema style works when trying to achieve truth in a documentary film. This work consints of two elements, the theoretical part and the short documentary. The theoretical part deals with the history, the truth, and the direct cinema- style in documentaries. The theoretical information of direct cinema has been used when making the short documentary. In the documentary Tuloaula 2 I have studied the way in which using direct cinema -style works in practise. The documentary has followed as strictly as possible the direct cinema style. I was the director, the cameraman and the editor of my documentary film. In the documentary film Tuloaula 2 it appeared that the direct cinema style works best when filming everyday life. By using this style it is easy for the director to observe and leave his own persona in the background. The strength in using the direct cinema style is that it enables the viewer to build his/her own impression on the subject. Even though the direct cinema style aims to achieve objectivity the director has to make numerous subjective choices during both the filming and the editing process. These subjective choices automatically effect the "truth" of the documentary film. The difficulty in a direct cinema style is the large amount of material. This often leads to a long editing phase, which is not often possible in the busy production schedules. The direct cinema style is not at its best when shooting people who are passive because their attention often focuses too much on the camera. In general, the best way to make a documentary film would be to use many documentary styles in one film and not to srictly concentrate on only one style.

Rejet de greffe et iontophorèse de corticoïdes: à propos de 3 cas [Corneal graft rejection and corticoid iontophoresis: 3 case reports].

This is the first report of three cases of severe acute corneal graft rejection, treated by transscleral methylprednisolone (Solumédrol) iontophoresis. The efficacy of the treatment was evaluated by corneal transparency, visual acuity and corneal inflammation parameters. The patient was treated with Solumédrol iontophoresis once a day for 3 days with a topical corticotherapy reduced to three drops of dexamethasone per day. Iontophoresis was performed, under topical anesthesia, and lasted 3 minutes with a 1.5-mA current. The subjective and objective tolerance of iontophoresis was good. No side-effect was observed. Corneal transparency and visual acuity improved rapidly after the second iontophoresis procedure. These observations show that Solumédrol iontophoresis might be an alternative to pulse therapy in the treatment of corneal graft rejection. Further comparative studies are necessary to confirm these preliminary observations.

Dignity in care: where next for nursing ethics scholarship and research?

Dignity is recognised as both a central and also a contested value in bioethics discourse. The aim of this manuscript is to examine some of the key strands of the extensive body of dignity scholarship and research literature as it relates to nursing ethics and practice. The method is a critical appraisal of selected articles published in Nursing Ethics and other key manuscripts and texts identified by researchers in the UK and Brazil as influential. The results suggest a wide and rather confusing range of perspectives and findings albeit with some overall themes relating to objective and subjective features of dignity. In conclusion, the authors point to the need for more sustained philosophical engagement contextualising human dignity within a plurality of professional values. Future empirical work should explore what matters to patients, families, professionals and citizens in different cultural contexts rather than foregrounding qualitative research with such a contested concept.

Uusien tuotantotapojen haasteet : esimerkkitapauksina mobiili-TV ja monimediaisuus YLE Uutisissa

Opinnäytetyön tavoitteena oli selvittää, millaisia ovat uusien tuotantotapojen haasteet uudenlaiselle sisällöntuotannolle ja uutisympäristölle. Monimediaisen tuotannon esimerkkitapauksiksi rajattiin mobiili-TV ja YLE Uutiset. Mobiili-TV:n tutkimusta varten kootulle testiryhmälle tehtiin subjektiivisen laadun kokemista mittaava MOS-testi (Mean Opinion Score), jossa selvitettiin testattavien mielipiteitä matkapuhelimen kautta esitettyjen videotiedostojen kuvan- ja äänenlaadusta sekä eri pakkaustapojen käyttökelpoisuudesta mobiili-TV:ssä. Testillä haettiin esille myös sisällöllisesti sopiva ja käyttökelpoinen suhde, jolla mobiili-TV:n lähetteen kokonaiskaistanleveys olisi kuvan ja äänen välillä hyvä jakaa. Lisäksi samalla testiryhmällä tutkittiin, mitä mobiili-TV:stä yleensä tiedetään, millaisena palvelu koetaan ja millaista sisältöä siihen kaivattaisiin. Tämän kuluttajatutkimuksen mukaan mobiili-TV:hen soveltuvimmiksi sisältötyypeiksi koettiin uutiset, ajankohtaisohjelmat ja osin urheilu. Mobiili-TV:ssä ei ole vielä paljoakaan tarjontaa, joten väline on suurelle yleisölle oikeastaan täysin tuntematon. Testiryhmän mielestä se voisi kuitenkin joissakin tilanteissa korvata tai täydentää perinteisen TV-vastaanottimen käyttöä. Mobiili-TV:n sisältötyyppitutkimuksen lisäksi tutkittiin YLE Uutisten sisällöntuotantomenettelyjä. Teemahaastattelujen avulla selvitettiin, millainen on toimituksen tuotantotapa, miten ylivälineellinen sisällöntuotanto siellä mahdollisesti toteutuu, millainen on sen mahdollinen mobiili-TV-palvelu ja miten siellä suhtaudutaan niin sanottuun kansalaisjournalismiin. Haastattelujen johtopäätöksinä YLE Uutisissa ei vielä toteudu aito ylivälineellinen tuotanto, mutta merkkejä muutoksesta on näkyvissä. Kansalaisjournalismin nousu on havaittu, mutta käytännön vastauksia siihen ei vielä ole. YLE Uutisten nykyinen 3G-matkapuhelimillakin käytettävä internet-TV-palvelu on toteutettu suoratoistopalveluna (engl. streaming), eikä vielä DVB-H-verkkotekniikkaa hyödyntäen, joten se on teknisesti melko matalalaatuista. Esimerkkinä toteutuneesta ylivälineellisestä tuotannosta on opinnäytetyössä esitelty Kansainvälisen Jean Sibelius -viulukilpailun monimediainen uutispalvelu. Lopuksi esitetään tutkimuksen pohjalta löytyneitä mahdollisuuksia, jotka tukevat YLE Uutisten tuotannon järjestämistä ylivälineelliseksi ja kansalaisten sisällöntuotantoa. aktivoivaksi.

Absence of progression as assessed by response evaluation criteria in solid tumors predicts survival in advanced GI stromal tumors treated with imatinib mesylate: the intergroup EORTC-ISG-AGITG phase III trial.

PURPOSE: From February 2001 to February 2002, 946 patients with advanced GI stromal tumors (GISTs) treated with imatinib were included in a controlled EORTC/ISG/AGITG (European Organisation for Research and Treatment of Cancer/Italian Sarcoma Group/Australasian Gastro-Intestinal Trials Group) trial. This analysis investigates whether the response classification assessed by RECIST (Response Evaluation Criteria in Solid Tumors), predicts for time to progression (TTP) and overall survival (OS). PATIENTS AND METHODS: Per protocol, the first three disease assessments were done at 2, 4, and 6 months. For the purpose of the analysis (landmark method), disease response was subclassified in six categories: partial response (PR; > 30% size reduction), minor response (MR; 10% to 30% reduction), no change (NC) as either NC- (0% to 10% reduction) or NC+ (0% to 20% size increase), progressive disease (PD; > 20% increase/new lesions), and subjective PD (clinical progression). RESULTS: A total of 906 patients had measurable disease at entry. At all measurement time points, complete response (CR), PR, and MR resulted in similar TTP and OS; this was also true for NC- and NC+, and for PD and subjective PD. Patients were subsequently classified as responders (CR/PR/MR), NC (NC+/NC-), or PD. This three-class response categorization was found to be highly predictive of further progression or survival for the first two measurement points. After 6 months of imatinib, responders (CR/PR/MR) had the same survival prognosis as patients classified as NC. CONCLUSION: RECIST perfectly enables early discrimination between patients who benefited long term from imatinib and those who did not. After 6 months of imatinib, if the patient is not experiencing PD, the pattern of radiologic response by tumor size criteria has no prognostic value for further outcome. Imatinib needs to be continued as long as there is no progression according to RECIST.

Evaluation of oxidative stress parameters and metabolic activities of nurses working day and night shifts

The aim of this study was to evaluate the oxidative stress and metabolic activities of nurses working day and night shifts. Intensive care unit (ICU) (n=70) and ordinary service (OS) nurses (n=70) were enrolled in the study. Just before and the end of the shifts, blood samples were obtained to measure the participants' oxidative stress parameters. Metabolic activities were analyzed using the SenseWear Armband. Oxidative stress parameters were increased at the end of the shifts for all OS and ICU nurses compared to the beginning of the shifts. Compared to the OS nurses, the ICU nurses' TAS, TOS, and OSI levels were not significantly different at the end of the day and night shifts. The metabolic activities of the OS and ICU nurses were found to be similar. As a result, the OS and ICU nurses' oxidative stress parameters and metabolic activities were not different, and all of the nurses experienced similar effects from both the day and night shifts.

Condom use with steady partners among heterosexual people living with HIV in Europe: testing the information-motivation-behavioral skills model.

Guided by a modified information-motivation-behavioral skills model, this study identified predictors of condom use among heterosexual people living with HIV with their steady partners. Consecutive patients at 14 European HIV outpatient clinics received an anonymous, standardized, self-administered questionnaire between March and December 2007. Data were analyzed using descriptive statistics and two-step backward elimination regression analyses stratified by gender. The survey included 651 participants (n = 364, 56% women; n = 287, 44%). Mean age was 39 years for women and 43 years for men. Most had acquired HIV sexually and more than half were in a serodiscordant relationship. Sixty-three percent (n = 229) of women and 59% of men (n = 169) reported at least one sexual encounter with a steady partner 6 months prior to the survey. Fifty-one percent (n = 116) of women and 59% of men (n = 99) used condoms consistently with that partner. In both genders, condom use was positively associated with subjective norm conducive to condom use, and self-efficacy to use condoms. Having a partner whose HIV status was positive or unknown reduced condom use. In men, higher education and knowledge about condom use additionally increased condom use, while the use of erectile-enhancing medication decreased it. For women, HIV disclosure to partners additionally reduced the likelihood of condom use. Positive attitudes to condom use and subjective norm increased self-efficacy in both genders, however, a number of gender-related differences appeared to influence self-efficacy. Service providers should pay attention to the identified predictors of condom use and adopt comprehensive and gender-related approaches for preventive interventions with people living with HIV.

Complications of shoulder arthroplasty for osteoarthritis with posterior glenoid wear.

BACKGROUND: Anatomical total shoulder arthroplasty (TSA) for glenohumeral osteoarthritis (OA) and severe posterior glenoid wear may entail early postoperative complications (recurrence of posterior subluxation, glenoid loosening). To avoid these mechanical problems, reverse shoulder arthroplasty (RSA) has recently been proposed, mainly for its intrinsic stability. Our purpose was to present the results of TSA and RSA in glenohumeral OA with posterior glenoid wear of at least 20°. HYPOTHESIS: By virtue of its constrained design, RSA could prevent recurrence of posterior subluxation and limit the occurrence of mechanical complications. MATERIALS AND METHODS: A consecutive series of 23 patients (27 shoulders) were treated for glenohumeral OA with total shoulder prostheses: 19 TSAs and 8 RSAs. Mean age was 70years (range, 47-85years), mean retroversion angle 28° (20°-50°) and mean subluxation index 74% (57-89%). Constant Score, Subjective Shoulder Value (SSV), QuickDASH and Simple Shoulder Test (SST) were measured, and radiological examinations were performed at a mean follow-up of 52months (24-95months). RESULTS: TSA and RSA patients respectively displayed Constant Scores of 65 and 65, SSV of 79% and 74%, QuickDASH of 16 and 27, and SST of 88 and 78. Two patients underwent surgical revision of TSA because of glenoid loosening; 52% of TSA patients presented complete radiolucent lines and 11% recurrence of posterior subluxation. CONCLUSION: Complications are frequently observed after shoulder arthroplasty for OA with severe glenoid retroversion. RSA could be an alternative to TSA for selected patients, independently of rotator cuff status. Studies on RSA in this specific indication with longer follow-up are now needed. LEVEL OF EVIDENCE: Level IV; retrospective case series.

Usage analysis of the Nursing Activities Score in two Spanish ICUS

The aim of this study was to analyze the discourse of health managers on aspects related to delay in tuberculosis diagnosis. This was a qualitative research study, conducted with 16 Family Health Unit managers. The empirical data were obtained through semi-structured interviews. The analysis was based on the theoretical framework of the French school of discourse analysis. According to the managers’ statements, the delay in tuberculosis diagnosis is related to patient and health service aspects. As for patient aspects, managers report fear, prejudice and lack of information as factors that may promote a delayed diagnosis. Regarding health service aspects, structural problems and lack of professional skills were reported. The discourse of managers should be considered to qualify tuberculosis control actions and to prevent delays in diagnosis.

Knowledge and attitudes of nurses towards alcohol and related problems: the impact of an educational intervention

An exploratory study of quasi-experimental approach that aimed to verify the impact of an educational intervention on attitudes and knowledge of nurses towards alcohol use and associated problems. The sample included 185 nurses, divided into two groups: 84 submitted to a training course and formed the experimental group. Data were collected through a knowledge survey and an attitude scale. The attitudes of the participants of both groups were positive. There were no significant differences between groups in relation to knowledge. The strongest predictors of positive attitudes were possessed preparation to act with chemical dependents (OR = 2.18), "have received increased workload during graduation on the theme, 'alcohol and other drugs'" (OR = 1.70), and "completed graduate school" (OR = 2.59). The educational intervention had a positive impact on the attitudes of nurses towards alcoholics, work and interpersonal relationships with such clientele.
