Universalization of access to modern energy services in Indian households-Economic and policy analysis

Provision of modern energy services for cooking (with gaseous fuels)and lighting (with electricity) is an essential component of any policy aiming to address health, education or welfare issues; yet it gets little attention from policy-makers. Secure, adequate, low-cost energy of quality and convenience is core to the delivery of these services. The present study analyses the energy consumption pattern of Indian domestic sector and examines the urban-rural divide and income energy linkage. A comprehensive analysis is done to estimate the cost for providing modern energy services to everyone by 2030. A public-private partnership-driven business model, with entrepreneurship at the core, is developed with institutional, financing and pricing mechanisms for diffusion of energy services. This approach, termed as EMPOWERS (entrepreneurship model for provision of wholesome energy-related basic services), if adopted, can facilitate large-scale dissemination of energy-efficient and renewable technologies like small-scale biogas/biofuel plants, and distributed power generation technologies to provide clean, safe, reliable and sustainable energy to rural households and urban poor. It is expected to integrate the processes of market transformation and entrepreneurship development involving government, NGOs, financial institutions and community groups as stakeholders.

Finding design value in modern mundanity

This pictorial is a visual pondering of the potential hidden within the mundane aspects of everyday life. Grounded in the theoretical concepts of ‘design futuring’ and ‘undesign’, it is framed in a speculative context and seeks to propose avenues for thought within the design space. This paper is not a reflection of a design process, nor is it presenting new and novel concept designs. Instead, this paper combines visuals and literature to encourage the reader into a mode of theoretical and personal reflection on the open possibilities for the future of design - through the reimagining of the mundane.

Modern surgical treatment of otosclerosis

The modern unilateral surgical treatment of otosclerosis started in 1956. Simultaneous bilateral surgery has not been reported in stapes surgery and in case of bilateral otosclerosis ears are operated in two different sessions. Simultaneous surgery would give the patient the opportunity to gain advantages of bilateral hearing within one session, with less time spent in hospital and on sick leave. The mechanism for vestibular symptoms and the exact end organ affected after surgery is still unveiled. This thesis presents the results of experimental simultaneous bilateral stapes surgery, and vestibular symptoms and findings before and after unilateral stapes surgery. In addition, we explore reasons for outpatient failures in otosclerosis surgery. -- Study I examines the outcome of simultaneous bilateral surgery. Hearing was evaluated with standard pure tone and speech audiograms and vestibular apparatus with visual feedback posturography (VFP) during the one-year follow-up. Subjective symptoms and quality of life were assessed with questionnaires. In study II, reasons for outpatient failures in stapes surgery were explored. Forty-seven consecutive stapedotomies and stapedectomies performed by the same surgeon were included, and the effect of failures on hearing results were analysed. Vestibular symptoms and the end organ(s) affected after stapes surgery were investigated in studies III and IV. With video-oculography (VOG), nystagmus was measured preoperatively, and at one week, one month and 3 months postoperatively in the first phase (III). In the second phase (IV), recordings were obtained some hours postoperatively. The hearing results of the simultaneous bilateral surgery were comparable with unilateral surgeries reported. Recovery from the surgery was fast. Significant improvement in performance and quality of life was noted already month after operation in subjective evaluations. Based on these results, simultaneous bilateral surgery is a suitable approach in bilateral otosclerosis Significantly more outpatient failures occurred for medical reasons in the stapedectomy group (13%) than in the stapedotomy group (2%). Stapedotomy should be favoured if outpatient surgery is planned. However, unplanned admission did not worsen the prognosis. VOG measurements in study III did not show any specific type of nystagmus in patients having vestibular symptoms postoperatively. However, VOG measurements immediately after surgery (IV) revealed nystagmus consistent with a minor disturbance of the semicircular canals in 33% of the patients. Subjectively, half of the patients reported vestibular symptoms that were probably of diverse origin, and could have originated from both otolith and semicircular canal parts of the vestibular organ. Since vestibular symptoms and signs are mild, patients may be safely discharged some hours after stapes surgery.

Modern computed tomography techniques in stroke management

Technological development of fast multi-sectional, helical computed tomography (CT) scanners has allowed computed tomography perfusion (CTp) and angiography (CTA) in evaluating acute ischemic stroke. This study focuses on new multidetector computed tomography techniques, namely whole-brain and first-pass CT perfusion plus CTA of carotid arteries. Whole-brain CTp data is acquired during slow infusion of contrast material to achieve constant contrast concentration in the cerebral vasculature. From these data quantitative maps are constructed of perfused cerebral blood volume (pCBV). The probability curve of cerebral infarction as a function of normalized pCBV was determined in patients with acute ischemic stroke. Normalized pCBV, expressed as a percentage of contralateral normal brain pCBV, was determined in the infarction core and in regions just inside and outside the boundary between infarcted and noninfarcted brain. Corresponding probabilities of infarction were 0.99, 0.96, and 0.11, R² was 0.73, and differences in perfusion between core and inner and outer bands were highly significant. Thus a probability of infarction curve can help predict the likelihood of infarction as a function of percentage normalized pCBV. First-pass CT perfusion is based on continuous cine imaging over a selected brain area during a bolus injection of contrast. During its first passage, contrast material compartmentalizes in the intravascular space, resulting in transient tissue enhancement. Functional maps such as cerebral blood flow (CBF), and volume (CBV), and mean transit time (MTT) are then constructed. We compared the effects of three different iodine concentrations (300, 350, or 400 mg/mL) on peak enhancement of normal brain tissue and artery and vein, stratified by region-of-interest (ROI) location, in 102 patients within 3 hours of stroke onset. A monotonic increasing peak opacification was evident at all ROI locations, suggesting that CTp evaluation of patients with acute stroke is best performed with the highest available concentration of contrast agent. In another study we investigated whether lesion volumes on CBV, CBF, and MTT maps within 3 hours of stroke onset predict final infarct volume, and whether all these parameters are needed for triage to intravenous recombinant tissue plasminogen activator (IV-rtPA). The effect of IV-rtPA on the affected brain by measuring salvaged tissue volume in patients receiving IV-rtPA and in controls was investigated also. CBV lesion volume did not necessarily represent dead tissue. MTT lesion volume alone can serve to identify the upper size limit of the abnormally perfused brain, and those with IV-rtPA salvaged more brain than did controls. Carotid CTA was compared with carotid DSA in grading of stenosis in patients with stroke symptoms. In CTA, the grade of stenosis was determined by means of axial source and maximum intensity projection (MIP) images as well as a semiautomatic vessel analysis. CTA provides an adequate, less invasive alternative to conventional DSA, although tending to underestimate clinically relevant grades of stenosis.

Attitudes Towards Modern Living: The Mid-century Showrooms of Herman Miller and Knoll Associates

The independent manufacturer’s furniture showroom, as defined by Herman Miller and Knoll in the mid-twentieth century, presented a highly controlled and controllable context in which both companies and their designers familiarized American architects, designers and consumers with new ideas about living with modern furniture and architecture. Embracing consumerism within a modernist idiom, these mid-century furniture showrooms provided a unique interior typology wherein the reconciliation of modernism, mass-produced goods and personal expression was not only possible, but also accessible. Challenging long-held practices and beliefs within the nation’s conservative home furnishings market, Herman Miller and Knoll superseded retail buyers by reaching out directly to customers. The independently-run showrooms allowed both companies to engage their customers in a sophisticated and sustained proposition about the role of modern furniture and architecture in daily life. Examining the showrooms designed for Herman Miller and Knoll Associates during the latter 1940s and early 1950s, this article explores the ways in which these spaces were utilized as both laboratories and showcases, demonstrating the adaptability of modern furniture and interiors to individual lifestyles.

The Mid-Century Showroom: Knoll, Herman Miller and the Retail Exhibition of Modern American Design

Although occasionally illustrated and referenced in contemporary histories of modern furniture and design, there is surprisingly little critical discussion or consideration of the role of the showroom in the promotion and dissemination of modern design during the mid-twentieth century. In these years, when the American lifestyle was popularly articulated and forcefully propagandized, the furniture showroom served as a principle site of professional and public indoctrination. Appropriating display techniques from modern exhibition design to showcase the American lifestyle as an abstracted, spatially integrated art form, the showroom provided an unencumbered landscape ideally suited to camera’s lens and the public’s imagination. Leading modern American furniture manufacturers, such as Herman Miller and Knoll Associates collaborated with major cultural institutions as well as department stores and retailers to maximize exposure and consumer demand for their products. Through such integrated marketing and merchandising strategies, showrooms also contributed to the broader social project to educate American consumers about modern design and the advantages of modern living. Related to the many model home programs and “good design” exhibitions of the 1950s, the furniture showroom occupies a unique place within the history and discourse of the postwar era. The peculiarities of the furniture showroom and its position as a point of intersection between the trade and the consumer, the commercial and the cultural, and the aesthetic and the ideological form the focus of this study.

Fluorescent Fields: electric lighting and the rationalization of the modern corporate workplace

This study investigates the implications of the introduction of electric lighting systems, building technologies, and theories of worker efficiency on the deep spatial and environmental transformations that occurred within the corporate workplace during the twentieth century. Examining the shift from daylighting strategies to largely artificially lit workplace environments, this paper argues that electric lighting significantly contributed to the architectural rationalization of both office work and the modern office environment. Contesting the historical and critical marginalization of lighting within the discourse of the modern built environment, this study calls for a reassessment of the role of artificial lighting in the development of the modern corporate workplace. Keywords: daylighting, fluorescent lighting, rationalization, workplace design

Comment on “Whole-genome analyses resolve early branches in the tree of life of modern birds”

Jarvis et al. (Research Articles, 12 December 2014, p. 1320) presented molecular clock analyses that suggested that most modern bird orders diverged just after the mass extinction event at the Cretaceous-Paleogene boundary (about 66 million years ago). We demonstrate that this conclusion results from the use of a single inappropriate maximum bound, which effectively precludes the Cretaceous diversification overwhelmingly supported by previous molecular studies.

Siperiaa sanoiksi - uralilaisuutta teoiksi : Kai Donner poliittisena organisaattorina sekä tiedemiehenä antropologian näkökulmasta

The doctoral dissertation, entitled Siperiaa sanoiksi - uralilaisuutta teoiksi. Kai Donner poliittisena organisaattorina sekä tiedemiehenä antropologian näkökulmasta clarifies the early history of anthropological fieldwork and research in Siberia. The object of research is Kai Donner (1888-1935), fieldworker, explorer and researcher of Finno-Ugric languages, who made two expeditions to Siberia during 1911-1913 and 1914. Donner studied in Cambridge in 1909 under the guidance of James Frazer, A. C. Haddon and W. H. R. Rivers - and with Bronislaw Malinowski. After finishing his expeditions, Donner organized the enlistment of Finnish university students to receive military training in Germany. He was exiled and participated in the struggle for Finnish independence. After that, he organized military offensives in Russia and participated in domestic politics and policy in cooperation with C. G. E. Mannerheim. He also wrote four ethnographic descriptions on Siberia and worked with the Scandinavian Arctic areas researchers and Polar explorers. The results of this analysis can be sum up as follows: In the history of ethnographic research in Finland, it is possible to find two types of fieldwork tradition. The first tradition started from M. A. Castrén's explorations and research and the second one from August Ahlqvist's. Donner can be included in the first group with Castrén and Sakari Pälsi, unlike other contemporary philologists, or cultural researcher colleagues, which used the method of August Ahlqvist. Donner's holistic, lively and participant-observation based way of work is articulated in his writings two years before Malinowski published his thesis about modern fieldwork. Unfortunately, Donner didn't get the change to continue his researche because of the civil war in Finland, and due to the dogmatic position of E. N. Setälä. Donner's main work - the ethnohistorical Siberia - encloses his political and anthropological visions about a common and threatened Uralic nation under the pressure of Russian. The important items of his expeditions can be found in the area of cultural ecology, nutritional anthropology and fieldwork methods. It is also possible to prove that in his short stories from Siberia, there can be found some psychological factors that correlate his early life history.

Tekstin kielen automaattinen tunnistaminen

Tutkielman aiheena on kirjoitetun digitaalisessa muodossa olevan tekstin kielen automaattinen tunnistaminen. Tekstin kieli on usein tarpeellista identifioida, jotta tekstin jatkokäsittelyssä osataan toimia käyttäen oikeita menetelmiä. Tekstin kielen automaattinen tunnistaminen on internetissä olevan tekstimäärän ja kielivalikoiman kasvaessa tullut tärkeäksi näiden dokumenttien automaattisen käsittelyn esivaiheeksi. Kielen tunnistaminen on kieleltään tuntemattoman tekstin vertaamista joukkoon annettuja kieliä. Samoja tai hyvin läheisiä menetelmiä voidaan käyttää myös tekstin lajitteluun esimerkiksi aihealueiden suhteen. Tässä tutkielmassa esitellään tutkielmaa varten rakennetun kielentunnistimen kehitysvaiheet sekä sen suorituskyvyn evaluointia. Aluksi tutkielmassa paneudutaan muutamaan eri kielentunnistamisen menetelmään, sekä esitellään myös eräiden toteutettujen kielentunnistinten rakennetta niistä kirjoitettujen artikkelien perusteella. Tämän jälkeen tutkielmassa kerrotaan kuinka kielentunnistimen rakentamiseen luotiin harjoituskorpuksia. Harjoituskorpukset luotiin Wikipedian artikkeleista yhteensä 103 kielelle. Eri kielten harjoituskorpusten yhteenlasketuksi kooksi tuli yli miljardi sanetta. Jokaisesta harjoituskorpuksesta luotiin 7 kielimallia kullekin kielelle. Kielimallit ovat kielten sanojen n-grammien (yhdestä kuuteen) listoja sekä listoja kielten koko-naisista sananmuodoista. Harjoituskorpuksista luotuja kielimalleja ja muutamia eri menetelmiä yhdistelemällä rakennettiin useita erilaisia kielentunnistimia, joiden suoriutumista vertailtiin keskenään laajojen testitunnistusten avulla. Testien suorittamista varten muodostettiin Europarl-korpuksesta noin 200 miljoonan sanan testikorpuksia kymmenelle eurooppalaiselle kielelle. Testitunnistuksia tehtiin automatisoidusti useita miljoonia. Näiden testien tulosten perusteella päädyttiin kielentunnistimeen, joka käyttää hyväkseen kaikkia kielimalleja sekä kahta eri menetelmää. Tutkielmassa kehitetyn kielentunnistimen suoriutumista vertailtiin vielä joidenkin artikkeleissa esiteltyjen kielentunnistimien suoriutumiseen ja lopuksi tutkielmassa esitellään mahdollisuuksia tunnistimen jatkokehittämiseen.

Explorations in the distributional and semantic similarity of words

A straightforward computation of the list of the words (the `tail words' of the list) that are distributionally most similar to a given word (the `head word' of the list) leads to the question: How semantically similar to the head word are the tail words; that is: how similar are their meanings to its meaning? And can we do better? The experiment was done on nearly 18,000 most frequent nouns in a Finnish newsgroup corpus. These nouns are considered to be distributionally similar to the extent that they occur in the same direct dependency relations with the same nouns, adjectives and verbs. The extent of the similarity of their computational representations is quantified with the information radius. The semantic classification of head-tail pairs is intuitive; some tail words seem to be semantically similar to the head word, some do not. Each such pair is also associated with a number of further distributional variables. Individually, their overlap for the semantic classes is large, but the trained classification-tree models have some success in using combinations to predict the semantic class. The training data consists of a random sample of 400 head-tail pairs with the tail word ranked among the 20 distributionally most similar to the head word, excluding names. The models are then tested on a random sample of another 100 such pairs. The best success rates range from 70% to 92% of the test pairs, where a success means that the model predicted my intuitive semantic class of the pair. This seems somewhat promising when distributional similarity is used to capture semantically similar words. This analysis also includes a general discussion of several different similarity formulas, arranged in three groups: those that apply to sets with graded membership, those that apply to the members of a vector space, and those that apply to probability mass functions.

Aspekte der Melancholietherapie in Martin Luthers Trostbriefen

Pro gradu -tutkielmani tehtävänä on selvittää näkökulmia melankoliaterapiaan Martti Lutherin lohdutuskirjeissä. Lähteinä on ollut neljä lohdutuskirjettä sekä yksi kirje, joka muistuttaa sisällöltään lohdutuskirjettä. Metodina on ollut kirjeiden tyylillis-retorinen analyysi. Aihe on kiinnostava, koska Lutherin kirjeiden ja retoriikan tutkimus on ollut vähäistä verrattuna häntä koskevaan laajaan kansainväliseen tutkimukseen. Työn lähtökohtana on ollut, että yksi kirjallisuuden tärkeimmistä tehtävistä 1500-luvulla oli erilaisten melankolisten sairauksien parantaminen. Kirjallisuuden avulla voitiin torjua hengenvaarallisia melankolisia affekteja kuten epätoivoa, pelkoa, surua ja apatiaa. Lutherin lohdutuskirjeet soveltuvat hyvin melankoliaterapian tutkimiseen, koska ne on kirjoitettu lohtua tarvitseville ihmisille. Työn tutkimuskysymykset ovat: Mitä melankolian hoitokeinoja Luther mainitsee? Missä määrin Lutherin melankoliaterapia on sopusoinnussa 1500-luvulla vallinneiden hoitokäsitysten kanssa? Miten Luther hyödyntää retoriikan ja huumorin keinoja melankoliaterapiassaan? Työn teoriaosassa selvitetään 1500-luvun ihmiskäsitystä sekä teologisesta että lääketieteellisestä näkökulmasta ja esitellään ajalle tyypillisiä humoraaliopin mukaisia melankolian hoitokeinoja. Selvitetään myös retoriikan ja melankoliaterapian suhdetta toisiinsa. Analyysiosassa pääpaino on Lutherin käyttämissä retorisissa keinoissa, mutta siinä hyödynnetään myös teoriaosan havaintoja. Tutkielmassa kirjallisuustieteellinen ja teologinen näkökulma tukevat toisiaan. Kirjallisuustieteellisestä näkökulmasta lohdutuskirjeet on tutkittavissa retoriikan tarjoamien käsitteiden avulla, koska ne on kirjoitettu aikana, jolloin retoriikka oli tärkeä yliopistollinen oppiaine. Tutkielma huomioi myös aiheen teologisen näkökulman, koska ajan kieli on uskonnollisesti värittynyttä ja koska Lutherin melankoliaterapiaan kuuluu vahva hengellinen ulottuvuus. Ihmisen kyky lohduttaa rinnastuu Lutherilla Jumalan kykyyn lohduttaa ihmistä Raamatun sanan kautta. Lutherille Jumala on reetori, jonka työväline on Raamatun pyhä sana. Puhutulla ja kirjoitetulla sanalla on Lutherin melankoliaterapiassa erityisen keskeinen merkitys. Tutkielmani osoittaa, että sekä Lutherin käyttämät retoriset keinot että hänen melankoliaterapiansa ovat suuressa määrin sopusoinnussa 1500-luvun retoriikan ja lääketieteen oppien kanssa. Luther käyttää melankoliaterapiassaan laajasti apuna erilaisia retorisia keinoja kuten toistoa, variaatiota, metaforaa ja esimerkkikertomuksia. Lutherin mainitsemat hoitokeinot kuten esimerkiksi metsästys, ratsastus, syöminen ja juominen, pelien pelaaminen, leikinlasku ja ystävien kanssa seurustelu ovat sopusoinnussa ajan hoitokäsitysten kanssa. Kirjeissä esiintyy myös lääketieteellisestä ja uskonnollisesta näkökulmasta katsottuna kyseenalaisia hoitokeinoja kuten tyhjänpäiväisten juttujen kertominen ja paholaisen kiroileminen. Nämä neuvot ylittävät ajan melankoliaterapiaan kuuluvan kohtuullisuuden säännön, ja ne on ymmärrettävä niiden teologisesta merkityksestä käsin. Lutherille kohtuullisuuden säännön rikkominen on toisinaan sallittua, kun on kysymys vaikeasta paholaisen aiheuttamasta melankoliasta. Kristillinen usko näyttää Lutherille tarjoavan vapauden käyttää tiettyjä hoitokeinoja, joita vielä keskiajalla ei olisi hyväksytty. Toisinaan Luther näkee kirjeen vastaanottajaa kohdanneen vaikeuden Jumalan eikä paholaisen aikaansaannoksena. Tällaisissa tapauksissa melankolia nähdään Jumalan työnä ihmisessä, joka mahdollistaa hengellisen kääntymisen Jumalan, kaiken lohdutuksen Isän puoleen.
