El estatuto ontológico de la materia en Manuel Gois. A propósito del escotismo de los Conimbricenses
No full textIn the context of the late medieval diffusion of Scotism and nominalism, the Jesuit Manuel
Gois, author of commentaries to some Aristotelian works on the philosophy of nature,
receives some ideas of Henry of Ghent and Scotus (such as the actuality of prime matter and
the immediate inhesion of quantity in the matter), although moderating them within a substantially
Aristotelian position. After an initial presentation of John of saint Thomas’ critique
to the Cursus conimbricensis physical treatises and a succinct consideration of the notion of
matter according to the Augustinian-Scotist tradition and to Manuel Gois himself, the article
analyses three typical questions of Gois’ natural philosophy that are logically connected to
each other: the doctrine of the entitative act of matter, the possibility of a matter lacking all
form, supposito interventu divino, and the matter as the quantity immediate inhesion subject.169 K

Evolução histórica do conceito de savana e a sua relação com o cerrado brasileiro.
No full textAgrupar a vegetação de uma região, de um país ou do planeta em categorias de fácil reconhecimento parece, inicialmente, uma tarefa simples. Entretanto, os critérios, as observações subjetivas, as escalas e outras variáveis consideradas no método de classificação adotado dificultam que um mesmo padrão possa emergir nos diferentes sistemas propostos por distintos autores. Embora certa uniformidade na conceituação e na terminologia seja desejada, é muito difícil que um modelo universal defina ou represente fielmente uma tipologia vegetacional, uma vez que as paisagens apresentam variações e particularidades locais e regionais. Além disso, influenciam sobremaneira no produto final da classificação, o tamanho da área, a escala e a ordem hierárquica dos critérios e conceitos utilizados na separação das categorias.

Effectiveness of a group opt-in session on uptake and graduation rates for pulmonary rehabilitation
No full text Pulmonary rehabilitation (PR) is an effective intervention in the treatment of patients with chronic obstructive pulmonary disease (COPD). Unfortunately some patients offered this treatment either fail to take up the offer or fail to complete the course. Studies have indicated a number of factors influencing uptake and completion rates. We describe the introduction of an intervention, the group opt-in session (GOIS), prior to individualised baseline assessment and entry to the PR course, with the intention being to improve uptake and completion rates. A 1.5-hour-long GOIS was offered as the first face-to-face contact to all patients referred for PR. Drop-out rates at all stages of the pathway from referral to graduation were collected on 200 patients prior to the introduction of the GOIS (non-GOIS group) and compared to the first 400 patients following introduction (the GOIS group). Possible independent predictors of course uptake and completion were examined in the GOIS group. The proportion of referred patients taking up the offer of individualised baseline assessment or a GOIS was similar (75% vs. 72.2%, p value not significant [ns]). However, since in the GOIS group the opt-in session preceded the individualised baseline assessment and some patients opted-out, a smaller proportion of referred patients underwent this assessment than in the non-GOIS group (58.7% vs. 75%, p < 0.001). In addition, dropouts following individualised baseline assessments were also reduced (7% vs. 22%, p < 0.001). Both of these factors reduced ‘wasted’ assessments. Similar proportions of patients referred began the PR course in both groups (53% vs. 51.7%, ns), but a higher proportion of patients graduated in the GOIS group (87.9% vs. 76.4%, p < 0.05). Drop-out rates due to illness were similar in both groups (8.5% pre vs. 6.8% post, ns). However, drop-out rates not due to illness were much higher in the non-GOIS group (15.1% vs. 5.3%, p < 0.001). In the GOIS group, patients who did not attend the GOIS were, on average, younger (64.6 years vs. 69.7 years, p < 0.001) and had a higher mean percent predicted Forced Expiratory Volume (50.6% vs. 43.8%, p < 0.05) than those that did attend. A greater proportion of patients who opted in to the GOIS and attended the PR course lived less than 25 minutes from the PR centre than either those who did not attend the GOIS or who attended and then opted out (77.4% vs. 63%, p<0.005). The GOIS improved the graduation rates at The North Bristol Lung Centre PR Course and reduced wasted assessments. There was no effect on initial uptake. Analysis of the behaviour of patients invited to a GOIS suggested that age, lung function and travel distance were important factors influencing patient choice. </jats:p
The Effect of Graphic Organizers and Instructional Scaffolding on Argumentative Writing Performance Among TESL Undergraduates
No full textThe present study investigated the effect of graphic organizers and instructional scaffolding on argumentative writing performance among TESL undergraduates. The study employed a quasi-experimental research using the pre-test and post-test design involving 90 TESL undergraduates being placed equally in three different groups underwent lessons on argumentative essay writing using different delivery modes,
modes comprising of four stages of learning for a duration of four weeks. During the intervention period, three small groups of TESL undergraduates from the GOIS and GONI delivery modes were video-recorded to investigate on how they communicate in their groups. After the intervention, a semi-structured interview was carried out. A total of 9 students (GOIS, n=3; GONI, n=3; NGNI, n=3) were interviewed and the interviews were audio-recorded. The one-way ANCOVA was used to analyse the argumentative writing performance among the TESL undergraduates. The percentages were used to compare the overall percentages of Comm between the GOIS and GONI delivery modes while the qualitative data from the semi-structured interview of the three delivery modes were analysed using the constant comparative approach. Results showed that the group which underwent the GOIS delivery mode performed significantly better in the overall argumentative essay writing performance (p<.05) compared to their counterparts in the GONI and NGNI delivery modes. Additionally, in terms of the overall frequency of conjunctions and overall frequency of argumentative elements, the results indicated that both the GOIS and GONI groups performed significantly better (p<.05) than the NGNI group. In terms of overall percentages of , the GONI group outperformed the GOIS group. The findings from the semi-structured interview revealed that the GOIS group experienced learning better compared to the GONI and NGNI groups. The research confirmed that the GOIS and GONI delivery modes are effective in enhancing argumentative writing performance among TESL undergraduates. In line with this, the research ends with a recommendation for educators to adopt these delivery modes in t argumentative writing skills are enhanced.

AIRBORNE DIFFERENTIAL INTERFEROMETRY: X-BAND EXPERIMENTS
No full textIn this work we present the results of an airborne differential interferometry experiment carried out by using the ORBISAR X-band system. Use of a high track measurement accuracy allowed us to fulfill the requirements of [1] [2], where repeat pass phase accuracy has been quantified in terms of position measurement errors. The presented experiment can be considered a first step towards the development of operative airborne differential interferometry for accurate ground deformation monitoring
A multilocus, temperature stress-related gene expression profile assay in Acropora millepora, a dominant reef-building coral
No full textWe report an accurate multiplex reverse transcription quantitative polymerase chain reaction (RT–qPCR) assay, capable of reproducing gene expression profiles from 16 target genes [12 genes of interest (GOIs) and four reference genes (RGs)] in Acropora millepora, a common reef-building model coral species. The 12 GOIs have known or putative roles in the coral bleaching response, yet the method is not restricted to this particular assay and gene set. The procedure is based on the Beckman Coulter (Fullerton, CA, USA) GenomeLab™ GeXP Genetic Analysis System and bridges the gap between quantitative real-time PCR (qPCR) expression analysis of a single or a small number of genes and microarray gene expression surveys of thousands of genes. Despite large variation among biological replicates, the majority of GOIs were up-regulated (up to 4000%) in most colonies during a laboratory-based thermal stress experiment. Two genes, Nf-kβ2 and MnSod, were consistently up-regulated in all colonies tested, and we therefore propose these as candidate markers useful for population-level evaluations of thermal stress. Our assay provides an important new tool for coral bleaching studies; because of the lower cost, labour and amount of cDNA required compared with singleplex qPCR, population-level studies with large biological replication are feasible

A Fast Method for High-Resolution Voiced/Unvoiced Detection and Glottal Closure/Opening Instant Estimation of Speech
No full textWe propose a fast speech analysis method which simultaneously performs high-resolution voiced/unvoiced detection (VUD) and accurate estimation of glottal closure and glottal opening instants (GCIs and GOIs, respectively). The proposed algorithm exploits the structure of the glottal flow derivative in order to estimate GCIs and GOIs only in voiced speech using simple time-domain criteria. We compare our method with well-known GCI/GOI methods, namely, the dynamic programming projected phase-slope algorithm (DYPSA), the yet another GCI/GOI algorithm (YAGA) and the speech event detection using the residual excitation and a mean-based signal (SEDREAMS). Furthermore, we examine the performance of the aforementioned methods when combined with state-of-the-art VUD algorithms, namely, the robust algorithm for pitch tracking (RAPT) and the summation of residual harmonics (SRH). Experiments conducted on the APLAWD and SAM databases show that the proposed algorithm outperforms the state-of-the-art combinations of VUD and GCI/GOI algorithms with respect to almost all evaluation criteria for clean speech. Experiments on speech contaminated with several noise types (white Gaussian, babble, and car-interior) are also presented and discussed. The proposed algorithm outperforms the state-of-the-art combinations in most evaluation criteria for signal-to-noise ratio greater than 10 dB.CASElectrical Engineering, Mathematics and Computer Scienc
Detection of GAP-43 in Goldfish Brain
No full textThe concept of learning and memory is a neurological process believed to reside in the nervous system of living organisms. In particular the growth associated protein, GAP-43, has been shown to alter its state of phosphorylation via a protein kinase C mediated reaction following long term potentiation, a paradigm of learning and memory. Most recent studies of GAP-43 in goldfish (Carassius auratus L) have focused on its presence in regenerating or developing optic nerves. The present study seeks to determine the existence of GAP-43 in the goldfish brain and secondly, quantify phosphorylated isoforms of GAP-43 before and after active avoidance shock training
