Plant sex chromosomes: lost genes with little compensation.

In many animals, gene loss on Y chromosomes is compensated through altered expression of their X-chromosome homologue. Now, however, a new study in plants finds that even genes deleted from the Y show no dosage compensation.

Lost in translation: dietary management of cardiovascular risk factors is seldom implemented.

OBJECTIVE: To assess dietary management of cardiovascular risk factors (CVRFs) in the general population. METHOD: Cross-sectional study conducted between 2009 and 2012 on 4811 participants (2567 women, 58±11years) living in Lausanne, Switzerland. RESULTS: Sixteen percent of participants diagnosed with overweight/obesity reported a slimming diet. Slimming diet was associated with diagnosis of hypertension: Odds ratio and (95% confidence interval): 0.61 (0.40-0.93); older age [0.84 (0.58-1.21), 0.79 (0.53-1.18) and 0.47 (0.27-0.81) for [50-60[, [60-70[ and [70+ years, respectively]; female gender [1.84 (1.36-2.48)] and diagnosis of diabetes [2.16 (1.13-4.12)]. Only 8% of participants diagnosed with hypertension reported a low-salt diet. Low-salt diet was associated with antihypertensive drug treatment [2.17 (1.28-3.68)] and diagnosis of diabetes [2.72 (1.26-5.86)]. One-third of participants diagnosed with dyslipidemia reported a low-fat diet. Low-fat diet was associated with female gender [1.47 (1.17-1.86)]; older age [1.29 (0.89-1.87), 1.71 (1.18-2.48) and 2.01 (1.33-3.03) for [50-60[, [60-70[ and [70+ years, respectively]; hypolipidemic drug treatment [OR=1.68 (1.29-2.18)]; current smoking [0.70 (0.51-0.96)] and obesity [0.67 (0.45-1.00)]. Approximately half of participants diagnosed with diabetes reported an antidiabetic diet. Antidiabetic diet was associated with current smoking [0.44 (0.22-0.88)] and antidiabetic drug treatment [OR=3.26 (1.81-5.86)]. CONCLUSION: Dietary management of CVRFs is seldom implemented in Switzerland.

Rotuun, etnisyyteen, luokkaan ja sukupuoleen kytkeytyvät valtasuhteet ja niiden problematisointi Julia Alvarezin romaanissa How the García Girls Lost Their Accents

Pro gradu -tutkielmani käsittelee valtasuhteita rotuun, etnisyyteen, luokkaan ja sukupuoleen kytkeytyvinä historiallisina verkostoina ja niiden vaikutuksia ihmisten elämään. Tutkielman kohdetekstinä on dominikaanilaisamerikkalaisen kirjailijan Julia Alvarezin (s. 1950) esikoisromaani How the García Girls Lost Their Accents (1991). Alvarezin romaani on omaelämäkerrallinen, ja se perustuu osittain historiallisiin tositapahtumiin. Tutkimusotteeni on kontekstualisoiva; teos asetetaan osaksi laajempia historiallisia tapahtumia ja niiden muodostamia valtahierarkioita. Teos sijoittuu päähenkilöiden kotimaan, Dominikaanisen tasavallan, lisäksi Yhdysvaltoihin, jonne Garcían perheen isä, äiti ja neljä tytärtä pakenevat diktaattori Trujillon tyranniaa 1960-luvulla. Tutkimukseni teoreettinen viitekehys nojaa postkoloniaaliseen ja feministiseen kirjallisuudentutkimukseen, joiden pyrkimyksenä on hegemonisten rakenteiden purkaminen. Valtasuhteiden dekonstruktiivisen paljastamisen avulla tuotettuja ja väärinkerrottuja historioita ja ruumiita kirjoitetaan uudelleen. Pohdin Alvarezin esikoisromaanin valtasuhteita esimerkiksi Michel Foucault’n vallan teoriaa hyödyntäen, mutta liitän analyysiin myös feminististä teoriaa etenkin Judith Butlerin ajatusten avulla. Tarkastelen työssäni romaanin henkilöhahmojen elämää ja identiteettien muodostumista rotuun, etnisyyteen, luokkaan ja sukupuoleen kytkeytyvän problemaattisen valtajaon näkökulmasta, jolla on juuri Karibian alueella vahvat historialliset erityispiirteensä kolonialismin sekä sen jälkivaikutusten runtelemana alueena. Työssäni tutkitaan muun muassa kolonialismin ja siirtolaisuuden diskursseissa päähenkilöiden elämään vaikuttavia valtasuhteita, ja etenkin kulttuuristen ja seksuaalisten identiteettien muodostumista marginalisoiduilla raja-alueilla. Osoitan, kuinka teoksesta käyvät ilmi erilaisten mutkikkaiden rotuun, etnisyyteen, luokkaan ja sukupuoleen liittyvien valtasuhteiden vaikutukset etenkin naisten elämään ja identiteetteihin. Mielestäni Alvarez tuo kerronnallaan ilmi valtasuhteiden kontekstisidonnaisuutta ja samalla niiden mielivaltaista ja rakenteellista luonnetta. Valta ja vallitsevat kaksijakoiset valtajärjestykset ovat tuotettuja ja toimivat yleensä poliittisesti jonkin ryhmän hyväksi toisia ryhmiä sortaen. Keskeinen tutkimustulos on, että Alvarezin teoksessa usein implisiittisesti kuvatut, kauas historiaan kytköksissä olevat valtasuhteet vaikuttavat monin tavoin teoksen päähenkilöiden elämään ja identiteettien muodostumiseen.

From the 'Miracle' to the 'Lost Decade': intersectoral transfers and external credit in the Brazilian economy

The present paper examines the Brazilian experience from the 'Economic Miracle' to the 'Lost Decade'. Its aim is to advance an alternative measurement of the flows of extraordinary wealth (i.e. ground-rent and net external credit) available for appropriation in the Brazilian economy and to asses their relevance in sustaining the process of accumulation of industrial capital. That is done in order to provide further and more accurate evidence to the claim that the evolution of the Brazilian process of capital accumulation has been extremely dependent on the evolution of those masses of extraordinary wealth.

Palaeopigment accumulation and implcations for paleolimnology over the lost century for two Ontario lakes

Crawford Lake is a meromictic lake, which is 24 m deep and has an area of 2.5 ha, and has never been reported to have mixed below 16 m. Lady Evelyn Lake, which became a reservoir when a dam was built in 1916, is dimictic with a maximum depth of about 35 m. 1 My research proved that both native chlorophylls and the ratio of chlorophyll derivatives to total carotenoids were better preserved in the shallower lake (Crawford Lake) because it was meromictic. Thus the anaerobic conditions in Crawford Lake below 16 m (monimolimnion) provide excellent conditions for pigment preservation. Under such conditions, the preservation of both chlorophylls and carotenoids, including oscillaxanthin and myxoxanthophyll, are extremely good compared with those of Lady Evelyn Reservoir, in which anaerobic conditions are rarely encountered at the mud-water interface. During the period from 1500 to 1900 A. D. in Crawford Lake, the accumulation rates of oscillaxanthin and myxoxanthophyll were extremely high, but those of chlorophyll derivatives and total carotenoids were relatively low. This was correlated with the presence of a dense benthic mat of cyanobacteria near the lake's chemocline. Competition for light between the deep dwelling cyanobacteria and overlying phytoplankton in this meromictic lake would have been intensified as the lake became more and more eutrophic (1955-1991 A. D.). During the period from 1955 to 1991 A. D., the accumulation rates of chlorophyll derivatives and total carotenoids in the sediment core from Crawford Lake (0-7.5 cm, 1955-present) increased. During this same period, the accumulation rates of cyanobacterial pigments (Le. oscillaxanthin and myxoxanthophyll) declined as the lake became more eutrophic. Because the major cyanobacteria in Crawford Lake are benthic mat forming Lyngbya and Oscillatoria and not phytoplankton, eutrophication resulted in a decline of the mat forming algal pigments. This is important because in previous palaeolimnological studies the concentrations of oscillaxanthin and myxoxanthophyll have been used as correlates with lake trophic levels. The results of organic carbon a13c analysis on the Crawford Lake sediment core supported the conclusions from the pigment study as noted above. High values of a13c at the depth of 34-48 cm (1500-1760 A. D.) were related to a dense population of benthic Oscillatoria and Lyngbya living on the bottom of the lake during that period. The Oscillatoria and Lyngbya utilized the bicarbonate, which had a high a 13C value. Very low values were found at 0-7 cm in the Crawford sediment core. At this time phytoplankton was the main primary producer, which enriched 12C by photosynthetic assimilation.

"Man of science, man of faith" : Lost, consumer agency and the fate/free will binary in the post-9/11 context

In 2004, Lost debuted on ABC and quickly became a cultural phenomenon. Its postmodem take on the classic Robinson Crusoe desert island scenario gestures to a variety of different issues circulating within the post-9II1 cultural consciousness, such as terrorism, leadership, anxieties involving air travel, torture, and globalization. Lost's complex interwoven flashback and flash-forward narrative structure encourages spectators to creatively hypothesize solutions to the central mysteries of the narrative, while also thematically addressing archetypal questions of freedom of choice versus fate. Through an examination of the narrative structure, the significance of technological shifts in television, and fan cultures in Lost, this thesis discusses the tenuous notion of consumer agency within the current cultural context. Furthermore, I also explore these issues in relation to the wider historical post-9/II context.

"All The Best Cowboys Have Daddy Issues": [Post]Oedipal Fatherhood And Subjectivity In ABC's Lost

ABC's popular television series Lost has been praised as one of the most innovative programs in the history of broadcast television primarily due to its unique storytelling content and structure. In this thesis, I argue that in spite of its unconventional stances in terms of narrative, genre, and character descriptions, Lost still conforms to the conventional understanding of family, fatherhood, and subjectivity by perpetuating the psychoanalytic myth of the Oedipus complex. The series emphasizes the centrality of the father in the lives of the survivors, and constructs character developments according to Freud's essentialist and phallocentric conception of subjectivity. In this way, it continues the classic psychoanalytic tradition that views the father as the essence of one's identity. In order to support this argument, I conduct a discursive reading of the show's two main characters: Jack Shepherd and John Locke. Through such a reading, I explore and unearth the mythic/psychoanalytic importance of the father in the psychology of these fictional constructs.

Faith lost and regained : the evolution of Anne Rice's critique of christianity in The Vampire Chronicles

Ce mémoire réunit trois romans de la série Les Chroniques de vampires de la populaire écrivaine américaine Anne Rice (The Vampire Lestat, Memnoch the Devil et Blood Canticle) afin d'étudier l'évolution de sa critique de la religion à travers l'écriture. Une analyse précise et complète de Lestat de Lioncourt, le personnage principal de la série, est faite afin de mieux comprendre l'impact de la transformation spirituelle du protagoniste sur l'ensemble de l'oeuvre de Rice. Dans The Vampire Lestat, le rejet de toute forme de croyances religieuses de la part de Lestat ainsi que la déconstruction et l'érotisation de rituels religieux traditionnels reflètent l'influence de l'athéisme. Memnoch the Devil représente la transition entre le refus de croire de Lestat et son retour subséquent à la religion catholique. Finalement, Blood Canticle symbolise le retour vers la foi du protagoniste et de l'auteur, en plus de marquer la fin des Chroniques de vampires de Rice. L'analyse s'inspire d'éléments biographiques afin de démontrer l'importance de la religion dans les récits de Rice, sans toutefois considérer ses romans comme des autobiographies.

Gone with the internet - How the old education was lost

Despite its young history, Computer Science Education has seen a number of "revolutions". Being a veteran in the field, the author reflects on the many changes he has seen in computing and its teaching. The intent of this personal collection is to point out that most revolutions came unforeseen and that many of the new learning initiatives, despite high financial input, ultimately failed. The author then considers the current revolution (MOOC, inverted lectures, peer instruction, game design) and, based on the lessons learned earlier, argues why video recording is so successful. Given the fact that this is the decade we lost print (papers, printed books, book shops, libraries), the author then conjectures that the impact of the Internet will make this revolution different from previous ones in that most of the changes are irreversible. As a consequence he warns against storming ahead blindly and suggests to conserve - while it is still possible - valuable components of what might soon be called the antebellum age of education.

Lost in Research - Wissensmanagement in komplexen (psychoanalytischen) Forschungsprojekten

Die Wissenschaft weist im Zuge der Entwicklung von der Industrie- zu einer Wissensgesellschaft einschneidende Veränderungen in der Wissensordnung auf, welche sich bis hin zu einem zunehmenden Verlust der wissenschaftlichen Selbststeuerungsmechanismen bemerkbar machen und einen veränderten Umgang mit dem generierten Wissensschatz erfordern. Nicht nur Änderungen in der Wissensordnung und -produktion stellen die Psychoanalyse vor neue Herausforderungen: In den letzten Jahrzehnten geriet sie als Wissenschaft und Behandlungsverfahren zunehmend in die Kritik und reagierte mit einer konstruktiven Diskussion um ein dem Forschungsgegenstand – die Untersuchung unbewusster Prozesse und Fantasien – adäquates psychoanalytisches Forschungsverständnis. Die Auseinandersetzung mit Forderungen gesellschaftlicher Geldgeber, politischer Vertreter und Interessensgruppen wie auch der wissenschaftlichen Community stellt die Psychoanalyse vor besondere Herausforderungen. Um wissenschaftsexternen wie -internen Gütekriterien zu genügen, ist häufig ein hoher personeller, materieller, finanzieller, methodischer wie organisatorischer Aufwand unabdingbar, wie das Beispiel des psychoanalytischen Forschungsinstitutes Sigmund-Freud-Institut zeigt. Der steigende Aufwand schlägt sich in einer zunehmenden Komplexität des Forschungsprozesses nieder, die unter anderem in den vielschichtigen Fragestellungen und Zielsetzungen, dem vermehrt interdisziplinären, vernetzten Charakter, dem Umgang mit dem umfangreichen, hochspezialisierten Wissen, der Methodenvielfalt, etc. begründet liegt. Um jener Komplexität des Forschungsprozesses gerecht zu werden, ist es zunehmend erforderlich, Wege des Wissensmanagement zu beschreiten. Tools wie z. B. Mapping-Verfahren stellen unterstützende Werkzeuge des Wissensmanagements dar, um den Herausforderungen des Forschungsprozesses zu begegnen. In der vorliegenden Arbeit werden zunächst die veränderten Forschungsbedingungen und ihre Auswirkungen auf die Komplexität des Forschungsprozesses - insbesondere auch des psychoanalytischen Forschungsprozesses - reflektiert. Die mit der wachsenden Komplexität einhergehenden Schwierigkeiten und Herausforderungen werden am Beispiel eines interdisziplinär ausgerichteten EU-Forschungsprojektes näher illustriert. Um dieser wachsenden Komplexität psychoanalytischer Forschung erfolgreich zu begegnen, wurden in verschiedenen Forschungsprojekten am Sigmund-Freud-Institut Wissensmanagement-Maßnahmen ergriffen. In der vorliegenden Arbeit wird daher in einem zweiten Teil zunächst auf theoretische Aspekte des Wissensmanagements eingegangen, die die Grundlage der eingesetzten Wissensmanagement-Instrumente bildeten. Dabei spielen insbesondere psychologische Aspekte des Wissensmanagements eine zentrale Rolle. Zudem werden die konkreten Wissensmanagement-Tools vorgestellt, die in den verschiedenen Forschungsprojekten zum Einsatz kamen, um der wachsenden Komplexität psychoanalytischer Forschung zu begegnen. Abschließend werden die Hauptthesen der vorliegenden Arbeit noch einmal reflektiert und die geschilderten Techniken des Wissensmanagements im Hinblick auf ihre Vor- und Nachteile kritisch diskutiert.

Proactive Detection and Recovery of Lost Mobile Phones

This paper describes the successful implementation of a prototype software application that independently and proactively detects whether a mobile phone is lost or misused. When the mobile phone is detected as being lost or misused, the application takes steps to mitigate the impact of loss and to gather evidence. The goal is to aid in the recovery of the mobile phone. The prototype works regardless of the cellular infrastructure the mobile phone is operating in and makes minimum demands on the owner of the mobile phone. The prototype was developed on Nokia 6600 mobile phones that run Symbian Operating System 7.0s. Development was done using Nokia’s Series 60 Developer’s Platform 2.0.
