Sosiaalisen median työkalut ja käyttäjälähtöisen sisällön jakaminen
2014
Tämä pro gradu on katsaus sosiaalisen median työkaluista, joilla viitataan erilaisiin vuorovaikutteisiin internetissä toimiviin palveluihin. Tutkimus määrittelee sosiaalisen median teknologiasidonnaisena ja käyttäjälähtöisenä ilmiönä, johon liittyy palveluiden käytön yhteisöllinen luonne. Palvelukategoriat, joihin termillä voidaan viitata, jakautuvat tämän tutkimuksen osalta blogeihin, verkostopalveluihin, virtuaalisiin maailmoihin, yhteistyöperusteisiin projekteihin ja sisältöyhteisöihin. Näitä palveluita tarkastellaan niiden käyttöluonteen, käyttäjälähtöisyyden ja reaaliaikaisuuden mukaan. Muita palveluihin liittyviä mekanismeja ovat esimerkiksi linkittäminen, metadata ja suosittelujärjes…
Käyttäjien ja kehittäjien välinen viestintä tietojärjestelmien kehittämisessä : haasteita ja ratkaisuja
2017
Tutkielman tavoitteena oli selvittää ja kerätä yhteen aiemmassa tutkimuksessa havaittuja haasteita käyttäjien ja kehittäjien välisessä viestinnässä tietojärjestelmäkehityksen kontekstissa, sekä näihin haasteisiin esitettyjä ratkaisuja. Tutkimus toteutettiin kirjallisuuskatsauksena. Tutkimustulokset luokiteltiin median samanaikaisuuden teorian ja käyttäjä-kehittäjäviestinnän käsitteistön pohjalta johdetun teoreettisen viitekehyksen mukaisesti. Tutkimustuloksista voidaan todeta, että suurimmat haasteet käyttäjien ja kehittäjien välisessä viestinnässä liittyvät yhteisymmärryksen luomiseen ja vaatimusmäärittelyyn, ja suurimpana yksittäisenä tekijänä haasteita aiheuttavat erilaiset yksilölliset …
Explorando las desigualdades sociales y formas de contrarrestarlas
2019
Production of INCASI Project H2020-MSCA-RISE-2015 GA 691004 La propuesta de este artículo es presentar una experiencia actual de innovación docente en la que se vincula la enseñanza de la Sociología con la investigación desarrollada en el proyecto europeo INCASI: International Network for Comparative Analysis of Social Inequalities. La experiencia docente se aplica en la asignatura de Sociología, con alumnado de primer curso, del grado de Gestión y Administración Pública, de la Facultad de Derecho, de la Universidad de Barcelona. El eje central del trabajo desarrollado por el alumnado es realizar una investigación sociológica exploratoria sobre una desigualdad social y observar e idear polí…
L’ineffabile terza mediana dell'Anvur per l’area 12
2012
L'articolo affronta lo spinoso problema del ranking delle riviste giuridiche nell'ambito della procedura di abilitazione scientifica nazionale per professori associati e ordinari. In particolare si sofferma sui problemi di legittimità che derivano della sopravvenuta pubblicazione delle riviste di classe A e dalla eventuale introduzione della terza mediana a cui la detta pubblicazione prelude, nel quadro della critica della classificazione Anvur in disaccordo con i pareri espressi dalla comunità accademica. The article discusses the thorny problem of legal journals ranking, focusing it in relation to national scientific qualification procedure. In particular, it stays on problems of low-…
CT imaging findings of abdominopelvic vascular compression syndromes: what the radiologist needs to know.
2020
AbstractAbdominopelvic vascular compression syndromes include a variety of uncommon conditions characterized by either extrinsic compression of blood vessels by adjacent anatomical structures (i.e., median arcuate ligament syndrome, nutcracker syndrome, May-Thurner syndrome) or compression of hollow viscera by adjacent vessels (i.e., superior mesenteric artery syndrome, ureteropelvic junction obstruction, ureteral vascular compression syndromes, portal biliopathy). These syndromes can be unexpectedly diagnosed even in asymptomatic patients and the predisposing anatomic conditions can be incidentally discovered on imaging examinations performed for other indications, or they can manifest wit…
The Value of Median Nerve Sonography as a Predictor for Short- and Long-Term Clinical Outcomes in Patients with Carpal Tunnel Syndrome: A Prospective…
2016
Objectives To investigate the prognostic value of B-mode and Power Doppler (PD) ultrasound of the median nerve for the short- and long-term clinical outcomes of patients with carpal tunnel syndrome (CTS). Methods Prospective study of 135 patients with suspected CTS seen 3 times: at baseline, then at short-term (3 months) and long-term (15–36 months) follow-up. At baseline, the cross-sectional area (CSA) of the median nerve was measured with ultrasound at 4 levels on the forearm and wrist. PD signals were graded semi-quantitatively (0–3). Clinical outcomes were evaluated at each visit with the Boston Questionnaire (BQ) and the DASH Questionnaire, as well as visual analogue scales for the pat…
PANCREATICODUODENAL ARTERIES ANEURYSMS: EVALUATION OF FREQUENCY AND ASSOCIATION WITH CELIAC ARTERY STENOSIS DUE TO COMPRESSION BY MEDIAN ARCUATE LIGA…
2019
The aim of the study is to evaluate the prevalence of pancreaticoduodenal arteries (PDA) aneurysms in a large population, and to define possible correlations with celiac artery stenosis due to compression by the median arcuate ligament. Radiological reports of abdominal contrast-enhanced CT scans of 18,180 patients were scrutinized to identify patients with true PDA aneurysms. Two abdominal radiologists classified the aneurysms according to size, location and morphology and scored the presence of celiac artery stenosis due to either median arcuate ligament compression or atherosclerotic disease. Eleven true PDA aneurysms were identified in 10 patients. Nine out of 10 patients had stenosis o…
Bilateral activations in operculo‐insular area show temporal dissociation after peripheral electrical stimulation in healthy adults
2018
Interhemispheric transfer is necessary for sensory integration and coordination of body sides. We studied how somatosensory input from one body side may reach both body sides. First, we investigated with 17 healthy adults in which uni‐ and bilateral brain areas were involved in consecutive stages of automatic sensory processing of non‐nociceptive peripheral stimulation. Somatosensory evoked fields (SEFs) to electrical stimulation were recorded with 306‐channel magnetoencephalography in two conditions. First, SEFs were registered following sensory radial nerve (RN) stimulation to dorsal surface of the right hand and second, following median nerve (MN) stimulation at the right wrist. Cortical…
Further evaluation of plasma sphingomyelin levels as a risk factor for coronary artery disease
2006
Abstract Background Sphingomyelin (SM) is the major phospholipid in cell membranes and in lipoproteins. In human plasma, SM is mainly found in atherogenic lipoproteins; thus, high levels of SM may promote atherogenesis. Methods We investigated in a median follow up of 6.0 years the association of SM with the incidence of a combined endpoint (myocardial infarction and cardiovascular death) in stable and unstable patients, and its relation to other marker of atherosclerosis in 1,102 patients with angiographically documented CAD and 444 healthy controls. Results and discussion Logistic regression analysis showed that SM categorized by median was associated with an elevated risk for CAD (HR 3.2…
The effect of two sulphur-containing pesticides, fenitrothion and endosulfan, on glutathione (GSH) content and on GSH S-transferase and gamma-glutamy…
1988
The glutathione (GSH) system of Procambarus clarkii (P.c.), the American red crayfish, is used as a marker of the effects of Fenitrothion (FT) and Endosulfan (ES), organophosphorus and organochlorinated insecticides, respectively. This system has been shown to be sensitive to different heavy metals poisoning, thus it has a double interest as marker for environmental contamination and as a potential source of xenobiotics or their metabolites to humans, since it is being fished commercially. The GSH content of the organ decreased 24 h after treatment with FT. FT promotes a 2-fold induction of GSH S-transferase (GST) activity at 6 h which is followed by a decrease of it at 24 h. The latter coi…
