White under Black. Works from the imperceptible / 1. Blanca Casas Brullet: Make Say The large photographs of Espacespages (2009) work to transform the creative space of the blank page toward the enabled space of openness to the world. The image gives prominence to the emptiness of the room, almost a cell, in which an action takes place, dimly illuminated by a pair of windows that makes me think of two eyes that attentively contemplate the interior of a process of creation.

Internet s'ha convertit en una font extraordinària de recursos per una audiència en constant creixement arreu el món. A l'igual que en altres activitats de la nostra societat, el coneixement de la localització geogràfica d'aquests recursos i de la gent que hi accedeix és útil tant pels usuaris com pels proveïdors d'informació. La geolocalització IP, però, pot donar informació errònia o amb un nivell de precisió que no vagi més enllà de la referència a un país.Aquest treball recull els diferents actors que formen part de la geolocalització IP i s'ha analitzat el paper que juguen en aquest procés així com la seva influència en el nivell de fiabilitat i exactitud final. Amb aquests sòlids fonaments s'ha desenvolupat una aplicació per representar gràficament en un mapa la geolocalització IP d'un dispositiu i la dels nodes que formen el camí realitzat fins arribar-hi, així com tota la informació addicional que de cada IP s'ha pogut obtenir.El resultat ha estat una memòria tècnica de tot el treball de recerca juntament amb una aplicació que s'executa en l'entorn de Microsoft Windows i plataforma .NET, caracteritzada per la seva facilitat d'ús gràcies a un disseny simple molt intuïtiu i efectiu, la rapidesa d'execució per què aprofita la programació de fils, i un positiu impacte visual ja que fa servir l'API de Google Maps per a la representació visual de la traça.

This paper proposes an automatic hand detection system that combines the Fourier-Mellin Transform along with other computer vision techniques to achieve hand detection in cluttered scene color images. The proposed system uses the Fourier-Mellin Transform as an invariant feature extractor to perform RST invariant hand detection. In a first stage of the system a simple non-adaptive skin color-based image segmentation and an interest point detector based on corners are used in order to identify regions of interest that contains possible matches. A sliding window algorithm is then used to scan the image at different scales performing the FMT calculations only in the previously detected regions of interest and comparing the extracted FM descriptor of the windows with a hand descriptors database obtained from a train image set. The results of the performed experiments suggest the use of Fourier-Mellin invariant features as a promising approach for automatic hand detection.

Introduction: Neuronal oscillations have been the focus of increasing interest in the neuroscientific community, in part because they have been considered as a possible integrating mechanism through which internal states can influence stimulus processing in a top-down way (Engel et al., 2001). Moreover, increasing evidence indicates that oscillations in different frequency bands interact with one other through coupling mechanisms (Jensen and Colgin, 2007). The existence and the importance of these cross-frequency couplings during various tasks have been verified by recent studies (Canolty et al., 2006; Lakatos et al., 2007). In this study, we measure the strength and directionality of two types of couplings - phase-amplitude couplings and phase-phase couplings - between various bands in EEG data recorded during an illusory contour experiment that were identified using a recently-proposed adaptive frequency tracking algorithm (Van Zaen et al., 2010). Methods: The data used in this study have been taken from a previously published study examining the spatiotemporal mechanisms of illusory contour processing (Murray et al., 2002). The EEG in the present study were from a subset of nine subjects. Each stimulus was composed of 'pac-man' inducers presented in two orientations: IC, when an illusory contour was present, and NC, when no contour could be detected. The signals recorded by the electrodes P2, P4, P6, PO4 and PO6 were averaged, and filtered into the following bands: 4-8Hz, 8-12Hz, 15-25Hz, 35-45Hz, 45-55Hz, 55-65Hz and 65-75Hz. An adaptive frequency tracking algorithm (Van Zaen et al., 2010) was then applied in each band in order to extract the main oscillation and estimate its frequency. This additional step ensures that clean phase information is obtained when taking the Hilbert transform. The frequency estimated by the tracker was averaged over sliding windows and then used to compare the two conditions. Two types of cross-frequency couplings were considered: phase-amplitude couplings and phase-phase couplings. Both types were measured with the phase locking value (PLV, Lachaux et al., 1999) over sliding windows. The phase-amplitude couplings were computed with the phase of the low frequency oscillation and the phase of the amplitude of the high frequency one. Different coupling coefficients were used when measuring phase-phase couplings in order to estimate different m:n synchronizations (4:3, 3:2, 2:1, 3:1, 4:1, 5:1, 6:1, 7:1, 8:1 and 9:1) and to take into account the frequency differences across bands. Moreover, the direction of coupling was estimated with a directionality index (Bahraminasab et al., 2008). Finally, the two conditions IC and NC were compared with ANOVAs with 'subject' as a random effect and 'condition' as a fixed effect. Before computing the statistical tests, the PLV values were transformed into approximately normal variables (Penny et al., 2008). Results: When comparing the mean estimated frequency across conditions, a significant difference was found only in the 4-8Hz band, such that the frequency within this band was significantly higher for IC than NC stimuli starting at ~250ms post-stimulus onset (Fig. 1; solid line shows IC and dashed line NC). Significant differences in phase-amplitude couplings were obtained only when the 4-8 Hz band was taken as the low frequency band. Moreover, in all significant situations, the coupling strength is higher for the NC than IC condition. An example of significant difference between conditions is shown in Fig. 2 for the phase-amplitude coupling between the 4-8Hz and 55-65Hz bands (p-value in top panel and mean PLV values in the bottom panel). A decrease in coupling strength was observed shortly after stimulus onset for both conditions and was greater for the condition IC. This phenomenon was observed with all other frequency bands. The results obtained for the phase-phase couplings were more complex. As for the phase-amplitude couplings, all significant differences were obtained when the 4-8Hz band was considered as the low frequency band. The stimulus condition exhibiting the higher coupling strength depended on the ratio of the coupling coefficients. When this ratio was small, the IC condition exhibited the higher phase-phase coupling strength. When this ratio was large, the NC condition exhibited the higher coupling strength. Fig. 3 shows the phase-phase couplings between the 4-8Hz and 35-45Hz bands for the coupling coefficient 6:1, and the coupling strength was significantly higher for the IC than NC condition. By contrast, for the coupling coefficient 9:1 the NC condition gave the higher coupling strength (Fig. 4). Control analyses verified that it is not a consequence of the frequency difference between the two conditions in the 4-8Hz band. The directionality measures indicated a transfer of information from the low frequency components towards the high frequency ones. Conclusions: Adaptive tracking is a feasible method for EEG analyses, revealing information both about stimulus-related differences and coupling patterns across frequencies. Theta oscillations play a central role in illusory shape processing and more generally in visual processing. The presence vs. absence of illusory shapes was paralleled by faster theta oscillations. Phase-amplitude couplings were decreased more for IC than NC and might be due to a resetting mechanism. The complex patterns in phase-phase coupling between theta and beta/gamma suggest that the contribution of these oscillations to visual binding and stimulus processing are not as straightforward as conventionally held. Causality analyses further suggest that theta oscillations drive beta/gamma oscillations (see also Schroeder and Lakatos, 2009). The present findings highlight the need for applying more sophisticated signal analyses in order to establish a fuller understanding of the functional role of neural oscillations.

In the circum-Pacific ophiolitic belts, when no other biogenic constituents are found, radiolarians have the potential to provide significant biostratigraph- ic information. The Santa Rosa Accretionary Complex, which crops out in several half-windows (Carrizal, Sitio Santa Rosa, Bahia Nancite, Playa Naranjo) along the south shores of the Santa Elena Peninsula in northwestern Costa Rica, is one of these little-known ophiolitic mélanges. It contains various oceanic assemblages of alkaline basalt, radiolarite and polymictic breccias. The radiolarian biochronology presented in this work is mainly based by correlation on the biozonations of Carter et al. (2010), Baumgartner et al. (1995b), and O'Dogherty (1994) and indicate an Early Jurassic to early Late Cretaceous (early Pliensbachian to earliest Turonian) age for the sediments associated with oceanic basalts or recovered from blocks in breccias or megabreccias. The 19 illus- trated assemblages from the Carrizal tectonic window and Sitio Santa Rosa contain in total 162 species belonging to 65 genera. The nomenclature of tecton- ic units is the one presented by (Baumgartner and Denyer, 2006). This study brings to light the Early Jurassic age of a succession of radiolarite, which was previously thought to be of Cretaceous age, intruded by alkaline basalts sills (Unit 3). The presence of Early Jurassic large reworked blocks in a polymictic megabreccia, firstly reported by De Wever et al. (1985) is confirmed (Unit 4). Therefore, the alkaline basalt associated with the radiolarites of these two units (and maybe also Units 5 and 8) could be of Jurassic age. In the Carrizal tectonic window, Middle to early Late Jurassic radiolarian chert blocks associ- ated with massive tholeitic basalts and Early Cretaceous brick-red ribbon cherts overlying pillow basalts are interpreted as fragments of a Middle Jurassic oceanic basement accreted to an Early Cretaceous oceanic Plate, in an intra-oceanic subduction context. Whereas, the knobby radiolarites and black shales of Playa Carrizal are indicative of a shallower middle Cretaceous paleoenvironment. Other remnants of this oceanic basin are found in Units 2, 6, and 7, which documented the rapid approach of the depocentre to a subduction trench during the late Early Cretaceous (Albian-Cenomanian), to possibly early Late Cretaceous (Turonian).

Reproductive success is determined by the presence and timing of encounter of mates. The latter depends on species-specific reproductive characteristics (e.g. initiation/duration of the mating window), season, and reproductive strategies (e.g. intensity of choosiness) that may potentially mitigate constraints imposed by mating windows. Despite their potentially crucial role for fitness and population dynamics, limited evidence exists about mating window initiation, duration and reproductive strategies. Here, we experimentally tested the mechanisms of initiation and the duration of the common lizard's Zootoca vivipara mating window, by manipulating the timing of mate encounter and analyzing its effect on (re-)mating probability. We furthermore tested treatment effects on female reproductive strategies, by measuring female choosiness. The timing of mate encounter and season did not significantly affect mating probability. However, a longer delay until mate encounter reduced female choosiness. Re-mating probability decreased with re-mating delay and was independent of mating delay. This indicates that mating window initiation depends on mate encounter, that its duration is fixed, and that plastic reproductive strategies exist. These findings contrast with previous beliefs and shows that mating windows per se may not necessarily constrain reproductive success, which is congruent with rapid range expansion and absence of positive density-effects on reproductive success (Allee effects). In summary, our results show that predicting the effect of mating windows on reproduction is complex and that experimental evidence is essential for evaluating their effect on reproduction and reproductive strategies, both being important determinants of population dynamics and the colonization of new habitats.

Opinnäytetyön tarkoitus oli antaa ajankohtaista tietoa Helsingin Ammattikorkeakoulu Stadian opiskelijoiden hyvinvoinnista. Tutkimuksella kerättiin tietoa opiskelijoiden terveydentilasta, terveyskäyttäytymisestä, toimeentulosta, opiskeluympäristöstä, sekä opiskeluterveydenhuoltopalveluista. Aineisto kerättiin kyselytutkimuksella Stadian E-lomakkeen avulla. Tutkimus lähetettiin otokseen kuuluneille ammattikorkekoulu Stadian opiskelijoille (N=401) ryhmäsähköpostina. Tutkimuksen vastausprosentti oli 30,2 (N=121). Tutkimus toteutettiin keväällä 2007 ja tulokset analysoitiin syksyllä 2007 SPSS for Windows tilastollisella tietojenkäsittelyohjelmalla. Aineiston analysoinnissa käytettiin frekvenssejä, sekä ristiintaulukointia. Ammattikorkeakoulu Stadian opiskelijat voivat kohtalaisen hyvin: oman terveytensä hyväksi tai melko hyväksi arvioi vastaajista yli 70 %. Kuitenkin verrattuna muihin opiskelijahyvinvointitutkimuksiin ovat tulokset heikompia. Väsymystä ilmeni vastaajilla erittäin runsaasti verrattuna käyttämiimme tutkimuksiin: yli puolet vastanneista kärsi siitä vähintään viikottain. Muina terveyttä heikentävinä oireina ilmeni eniten niska- ja hartiakipuja, jännittyneisyyttä/hermostuneisuutta, päänsärkyä, vatsavaivoja, selän alaosankipuja, sekä ahdistuneisuutta, jotka olivat myös lisääntyneet verrattuna aikaisempiin tutkimuksiin. Stadian opiskelijoiden sosiaaliset suhteet olivat melko hyvässä kunnossa. Opiskelijoiden ruokailutottumukset olivat parantuneet hieman vuonna 2005 Stadiassa toteutetusta tutkimuksesta. Vastaajista noin 60 % ajatteli ruoan terveellisyyttä usein sitä hankkiessaan. Suurin osa vastaajista oli alkoholin kohtuu käyttäjiä. Alkoholista kokonaan kieltäytyvien määrä oli lisääntynyt, toisaalta myös säännöllisesti alkoholia kerran viikossa käyttävien määrä oli noussut. Suurin osa vastaajista oli normaalipainoisia. Yli 60 % vastaajista työskenteli opintojensa ohessa. Vastaajista kolmasosalle toimeentulo oli niukkaa ja epävarmaa. Stadiaan oltiin opiskeluympäristönä suhteellisen tyytyväisiä. Opiskeluterveydenhuoltopalveluja käytettiin vähäisesti. Palveluista oltiin tietoisia eri koulutusaloilla epätasaisesti ja myös niiden hyödyntämisessä oli eroavaisuuksia. Opiskelijoista yli puolet olisi valmiita maksamaan opiskeluterveydenhuoltopalveluista, jos se parantaisi niiden laatua. Jatkossa tulisi Stadian opiskelijoiden hyvinvointia seurata edelleen tasaisin väliajoin. Tutkimus kannattaa toteuttaa Stadian E-lomakkeen avulla sähköisesti ja huolehtia sen tehokkaasta markkinoinnista. Opiskeluterveydenhuoltopalveluista tulisi suorittaa erillinen lisätutkimus palveluiden parantamiseksi ja niiden käytön lisäämiseksi. Saatuja tutkimustuloksia tulisi hyödyntää parannettaessa opiskelijoiden hyvinvointia kehittämällä Stadian tarjoamia palveluita ja toimintatapoja.

Opinnäytetyön tavoitteena oli selvittää, kuinka tärkeänä Pietarin synnytyslaitos nro 9:n hoitohenkilökunta pitää potilasohjauksen eri osa-alueita raskaus-, synnytys- ja lapsivuodeaikana, sekä kuinka hoito toteutuu lapsivuodeosastolla. Suoritettu kysely oli samalla myös hankkeen loppukartoitus. Työ on osa moniammatillista yhteistyöhanketta (2003 -2007) Suomen ja Venäjän välillä. Teoreettisen viitekehyksen avulla tuodaan esille raskaudenaikaisen alkoholinkäytön ja tupakoinnin riskejä lääketieteellisestä näkökulmasta sekä selvitetään keinoja ohjata alkoholia käyttäviä tai tupakoivia raskaana olevia naisia ja perheitä. Tutkimusaineisto kerättiin strukturoidulla kyselylomakkeella 1.11-8.11.2006 Pietarin synnytyslaitos nro 9:n hoitohenkilökunnalta (n = 99). Vastanneet olivat kätilöitä tai sairaanhoitajia. Tulosten analysointi tehtiin SPSS for Windows 15 -ohjelmalla. Yleisesti ottaen vastaajat pitivät merkityksellisenä ohjata ja tukea äitejä sairaalassa sekä keskustella raskauteen, synnytykseen ja kotiutumiseen liittyvistä asioista. Vastanneiden mukaan äitejä kannustettiin omatoimisuuteen ja he saivat osallistua hoidon suunnitteluun. Ilmapiiri koettiin leppoisaksi ja mukavaksi sekä kannustavaksi ja tukevaksi, mutta myös synnyttäjää ja perhettä holhoavaksi. Kyselyssä kartoitetut potilasohjauksen kehittämisehdotukset kohdistuivat lähinnä henkilö- ja materiaaliresurssien lisäämiseen. Henkilökunnasta 77 % oli saanut WHO:n imetysohjaajakoulutuksen. Muista osa-alueista poiketen lähes 23 % vastanneista ei pitänyt lainkaan tärkeänä keskustella alkoholinkäytöstä ja tupakoinnista raskaus- ja lapsivuodeaikana. Vastaava luku vuoden 2004 alkukartoituksessa oli 40 %. Tulosten mukaan imetysohjaajakoulutuksen saannilla, koulutuksen pituudella tai iällä ei ollut merkitystä sen suhteen, pitikö tärkeänä keskustella alkoholinkäytöstä ja tupakoinnista äitien kanssa. Sen sijaan ne vastanneet, jotka eivät kokeneet tärkeäksi keskustella alkoholinkäytöstä, eivät kokeneet sen tärkeämmäksi myöskään tupakoinnista keskustelemista. Opinnäytetyö antaa tietoa Pietarin synnytyslaitos nro 9:n hoidon nykytilanteesta. Se tarjoaa valmiuksia alkoholinkäytöstä ja tupakoinnista ohjaamiseen sekä äitien raittiudessa ja savuttomuudessa pysymisen tukemiseen. Näin voidaan parantaa sekä syntyvien lasten että äitien itsensä terveyttä. Jatkossa olisi tärkeää selvittää miksi hoitotyöntekijät eivät osaa tai koe tarpeelliseksi keskustella alkoholinkäytöstä ja tupakoinnista äitien kanssa. Myös raskaana olevien naisten alkoholinkäytöstä ja tupakoinnista kaivattaisiin lisäselvitystä ilmiön ymmärtämiseksi ja selittämiseksi, sekä tehokkaiden interventiokeinojen löytämiseksi.
