The lung at high altitude
Annalisa Cogo
Multidisciplinary Respiratory Medicine , 2011, DOI: 10.1186/2049-6958-6-1-14
Abstract: A new classification of altitude levels based on the effects on performance and well-being has been recently proposed [1]: the decrease in partial pressure of oxygen reduces maximal oxygen uptake and impairs "aerobic" performance by reducing maximal aerobic power. Submaximal exercise performance is also impaired at altitude. When the acclimatization is not adequate, hypoxia triggers maladaptive responses that lead to various forms of high altitude illness or acute mountain sickness (AMS), characterized by headache plus gastrointestinal symptoms (anorexia, nausea) and sleep disturbances. AMS is present in 10-30% of subjects at altitudes between 2500 and 3000 m a.s.l. and is usually due to a fast ascent. It is well defined by the short phrase: "Too fast, too high". Less frequent, but much more serious, consequences are high-altitude cerebral edema (HACE), and high-altitude pulmonary edema (HAPE).The lung response to acute altitude exposure is mainly hyperventilation which, together with elevated heart rate, aims at achieving an adequate supply of oxygen to the tissues. At rest, ventilation increases by firstly increasing the tidal volume, at least up to 3500 m. Above this altitude, also the breathing rate significantly increases. Besides the compensatory response, other mechanisms affect lung physiology during hypoxic exposure: the increase of pulmonary artery pressure and endothelial permeability which can explain the extravascular lung fluid accumulation described in many papers [2]. It must be underlined that the interstitial fluid accumulation which affects a large part of climbers at high altitude should be considered a para-physiological mechanism and does not predict subsequent pulmonary edema [3].The role of the lung in the acute exposure to altitude was first described by Angelo Mosso, physiologist at the University of Torino, at the end of the 19th century. He very well pointed out the changes in ventilation and the reduction of lung volumes consistent with

Abstract: Objectives – This study evaluates the level to which virtual (asynchronous e-mail) reference services adhere to professional guidelines. Specifically, it addresses the following research questions: 1) To what extent do virtual reference services adhere to the American Library Association (ALA) Reference and User Services Association (RUSA) and the International Federation of Library Associations (IFLA) guidelines? 2) How does the level of adherence to RUSA or IFLA guidelines vary based on request type, user name, and institution? 3) Is there a correlation between outcome measures of reference transactions (accuracy, completeness, and satisfaction) and the level of adherence to RUSA or IFLA guidelines? Design – Unobtrusive evaluation of researcher-generated queries. Setting – Fifty-four academic libraries in North America. Subjects – A total of 324 queries were sent to the 54 libraries, with each library receiving six different types of requests from six different user names. Methods – Researchers developed two coding schemes for the guidelines (34 codes and 12 attributes for the RUSA guidelines and 33 codes and 10 attributes for the IFLA guidelines). Each of the six user names used represented an ethnic and/or religious group identity: Mary Anderson (Caucasian, Christian), Moshe Cohen (Caucasian, Jewish), Ahmed Ibrahim (Arab), Latoya Johnson (African American), Rosa Manuz (Hispanic), and Chang Su (Asian). The six request types were designed so that three would be answered (questions 1-3) and three would be out of scope and not answered (questions 4-6). The following queries were sent, individualized for each institution: 1) Dissertation query; 2) Sports team query; 3) Population query; 4) Subject query; 5) Article query; 6) Request for a PDF copy. The 324 queries were uploaded into NVivo 2 software, and all e-mail transactions were coded and analyzed. Main Results – Analysis of the 324 transactions from 54 libraries showed the following results:1) Low levels of adherence to both sets of guidelines;2) Varied levels of adherence based on request types and user names on both sets of guidelines;3) Variation in institutional rank according to different sets of guidelines;4) No correlation between user satisfaction and adherence to either set of guidelines. Conclusion – This study suggests that higher levels of virtual reference service effectiveness could be achieved by automatically integrating some less observed behaviours (e.g., thank you notes) into replies sent to users and by increasing librarians’ awareness of professional guidelines through training

Como andar sem poesia? a leitura de poemas na educa o infantil / How to go without poetry? the reading of poetry in nursery school

Abstract: O artigo reflete sobre a frui o do gênero poético por crian as ainda n o alfabetizadas a partir de momentos compartilhados com elas no cotidiano de escolas de Educa o Infantil. Essa vivência, vinculada ao projeto de pesquisa Poesia e infancia3, demonstrou a relevancia de possibilitar às crian as um contato intenso com a poesia, texto singular que as capacita a expressar, na sua linguagem, o modo como interagem com o outro e com o mundo. Através de encontros semanais com crian as de 4 a 6 anos de duas escolas da regi o do Vale do Rio Pardo/RS, foi possível perceber uma extrema abertura da infancia para os jogos vocabulares e sonoros. Na continuidade da pesquisa, pudemos estudar as características textuais mais valorizados pelas crian as na escuta de textos poéticos. Uma hipótese era a de que a audi o regular de poemas potencializava a repercuss o e a ressonancia, aspectos apontados por Gaston Bachelard como intrínsecos ao devaneio poético, experiência oportunizada pelaleitura/audi o da poesia e que faculta ao leitor encontrar “um n o-eu meu que me permite viver minha confian a de estar no mundo” (BACHELARD, 1988, p. 13)4. Ancorado nos resultados obtidos, estetexto defende a rima e o discurso predominante do poema como fatores essenciais para os pequenos experimentarem a ressonancia poética. Abstract The article reflects on the fruition of the poetic gender by illiterate children through the shared moments with them in the Nursery Schools’ daily. This living, linked to the Poesia e infancia14 research project, demonstrated the relevance in giving children an intense contact with poetry, singular text that enables them to express, in their own language, the way they interact with the other and the world. By means of weekly meetings with children from 4 to 6 years-old of two schools in the Rio Pardo/RS Valley Region, we could perceive an extreme opening of the childhood to the word and sonorous games. In the continuity of the research, we could study the textual characteristics that were more valued by children in the listening of poetic texts. One hypothesis was that the regular hearing of poems would enhance the repercussion and resonance, aspects pointed out by Gaston Bachelard as intrinsic to the poetic musing, experience given by the reading/hearing of the poetry and that allows the reader to find “a my non-I that permits living my confidence of being in the world” (BACHELARD, 1988, p. 13) 15. Anchored in the obtained results, this text defends the rhyme and predominant discourse in poem as essential factors to the little ones to experiment the poe

Abstract: Recent studies on international migration have paid special attention to the transnational perspective, a new branch of the sociology of migration studying the process through which migrants build social fields that link the countries of origin and destination. The economic transnationalism connected to the great phenomenon of remittances—financial, material or immaterial—is one relevant aspect of this field of study. Remittances are ambivalent because they can be interpreted either as a medium of consolidation of transnational ties or as a bond linking migrant women to the country of origin. Our target is, in fact, those migrant women who carry out in Italy a particular work of care: the badanti, or informal caregivers. As such, they constitute an important resource of the Italian welfare system, characterized as it is by an important family component. Any migratory phenomenon is, by nature, complex and dynamic, with different historical, economic and social characteristics. Moreover, it operates changes at many levels. The caring work done by badanti, as well as the transnational links represented by cross-border remittances, takes place and must be read within this broader dynamics. The research question for this paper is (exactly) that whether remittances are mainly bonds or mainly ties for badanti, relative to other migrant workers employed in the care sector. We use qualitative and quantitative data from the Prin 2004 research project1 concerning nationality, gender and class in new house holding work in Italy. After de
The pale horizon of the border: “Japanese” novels by Kazuo Ishiguro Un pallido orizzonte di confine: i romanzi ‘giapponesi’ di Kazuo Ishiguro

Abstract: Although Kazuo Ishiguro is considered one of the most representative novelists of contemporary literature in English, he was born in Japan and moved to England as a child. However, Japanese settings belong to the early years of his career as a writer. The Japanese images portrayed in the novels and short stories set in his homeland are inspired by his childhood memories, scenes watched in Japanese films and stereotypes known to Western readers, used in order to capture their attention. In his novels, Ishiguro reduces the distance between East and West with the particular use of the English language, described by the writer as a “pseudotranslation” or a “translationese” language. Setting his first novels and short stories in Japan, the writer plays the role of a translator translating into English a Japanese novel that doesn’t exist. Ishiguro acts as a translator using English to explain Japanese culture to his Western readers. In studying the Japanese and English critics of Ishiguro’s works, examples from his novels, as well as from the Japanese translations of his novels, it becomes unmistakably clear that this writer is capable of reducing the boundaries between the East, the West and their cultures. Nonostante Kazuo Ishiguro sia considerato uno dei maggiori romanzieri della letteratura contemporanea scritta in inglese, è nato in Giappone, e si è trasferito in Gran Bretagna da bambino. Durante i primi anni della sua carriera ha ambientato alcuni suoi romanzi e racconti nella sua madrepatria. Il Giappone che vi descrive si ispira ai suoi ricordi d’infanzia, alle scene viste nei film giapponesi e agli stereotipi che i lettori occidentali hanno del paese del Sol Levante. Attraverso i suoi romanzi, Ishiguro riduce le distanze tra l’Oriente e l’Occidente con un uso particolare della lingua inglese, descritta dallo stesso autore come ‘pseudotranslation’ o ‘translationese language’. Decidendo di ambientare i suoi primi romanzi e racconti in Giappone, lo scrittore svolge il ruolo di un traduttore che traduce in inglese un romanzo in giapponese che non esiste nella realtà. In questo modo Ishiguro si comporta come un traduttore che usa la lingua inglese per spiegare ai lettori occidentali la cultura giapponese e per ridurre il confine tra Oriente e Occidente e tra le due tradizioni.

Das Potenzial der "Back-talk"-Methode bei Fokusgruppen: gegen die fehlende Rückbindung der qualitativen Migrationsforschung Back-talk Focus Groups as a Follow-Up Tool in Qualitative Migration Research: The Missing Link? Investigando el potencial del "back-talk focus group": el eslabón perdido de la investigación cualitativa sobre migraciones?

Abstract: Der folgende Beitrag thematisiert das spezielle, wenn auch kaum genutzte Verfahren der so genannten "Back-talk"-Fokusgruppe, das darin besteht, mit Forschungsteilnehmer(inne)n Forschungsresultate zu diskutieren. Nach der dreij hrigen Untersuchung muslimischer Jugendlicher in Italien verdeutlicht die Verfasserin die Relevanz, Raum für einen weiteren Forschungsabschnitt, den "Back-talk" zu schaffen. In ihren Ausführungen argumentiert sie, dass sich insbesondere Fokusgruppen dazu eignen, signifikante Rückmeldungen zu Forschungsergebnissen zu generieren, und nennt drei Gründen hierfür: erstens stimuliere es die Selbstreflexivit t der Forschenden und erm gliche die überprüfung alter und die Bildung neuer Kategorien; zweitens erm chtige es die Forschungsteilnehmer(innen), eine gr ere Rolle im Forschungsprozess einzunehmen und reflexivere Praktiken in der Zivilgesellschaft zu etablieren; und drittens garantiere es die verantwortungsvolle Verbreitung potenziell sensitiver Inhalte in einer teilweise divergenten und politisierten Zuh rerschaft. In Zusammenhang mit der generellen Frage, wie "Back-talk"-Fokusgruppen zur Bildung einer reflexiveren und sozial verantwortungsbewussteren Forschungskultur beitragen k nnen, analysiert der vorliegende Beitrag den empirischen Fall einer "Back-talk"-Fokusgruppe junger italienischer Moslems und zeigt ihren Dissens, ihre Zustimmung sowie ihre Empfehlungen bei der Diskussion von Forschungsergebnissen. Abschlie end reflektiert die Autorin die St rken der "Back-talk" Fokusgruppen und nennt auch einige Schw chen dieses "fehlenden Links" in der qualitativen Migrationsforschung. URN: urn:nbn:de:0114-fqs060352 This paper reflects upon a specific, but rarely used, methodological tool we term back-talk focus group, which consists in drawing together research participants to discuss research findings. After three years of research on Muslim youth in Italy we will show the importance of creating space for a further research stage called "back-talk". The paper will argue that focus group is a very useful tool to make a powerful back-talk for three main reasons. First it stimulates the reflexivity of the researcher by allowing to generate new data. Second, it empowers participants by allowing them greater role in the research process and more reflexive practices in civil society. Third, it ensures responsible dissemination of potentially sensitive issues to a potentially diverse and highly politicised audience. Following a general discussion of how back-talk focus group could contribute to create a research culture more reflexive and more
