Full textAbstract:
Many developed democracies are experiencing high immigration, and public attitudes likely shape their policy responses. Prior studies of ethnocentrism and stereotyping make divergent predictions about anti-immigration attitudes. Some contend that culturally distinctive immigrants consistently generate increased opposition; others predict that natives’ reactions depend on the particular cultural distinction and associated stereotypes. This article tests these hypotheses using realistic, video-based experiments with representative American samples. The results refute the expectation that more culturally distinctive immigrants necessarily induce anti-immigration views: exposure to Latino immigrants with darker skin tones or who speak Spanish does not increase restrictionist attitudes. Instead, the impact of out-group cues hinges on their content and related norms, as immigrants who speak accented English seem to counteract negative stereotypes related to immigrant assimilation.

"On the Potentiality of UAV Multispectral Imagery to Detect Flavescence dorée and Grapevine Trunk Diseases." Remote Sensing 11, no. 1 (December 23, 2018): 23. http://dx.doi.org/10.3390/rs11010023.
Full textAbstract:
Among grapevine diseases affecting European vineyards, Flavescence dorée (FD) and Grapevine Trunk Diseases (GTD) are considered the most relevant challenges for viticulture because of the damage they cause to vineyards. Unmanned Aerial Vehicle (UAV) multispectral imagery could be a powerful tool for the automatic detection of symptomatic vines. However, one major difficulty is to discriminate different kinds of diseases leading to similar leaves discoloration as it is the case with FD and GTD for red vine cultivars. The objective of this paper is to evaluate the potentiality of UAV multispectral imagery to separate: symptomatic vines including FD and GTD (Esca and black dead arm) from asymptomatic vines (Case 1) and FD vines from GTD ones (Case 2). The study sites are localized in the Gaillac and Minervois wine production regions (south of France). A set of seven vineyards covering five different red cultivars was studied. Field work was carried out between August and September 2016. In total, 218 asymptomatic vines, 502 FD vines and 199 GTD vines were located with a centimetric precision GPS. UAV multispectral images were acquired with a MicaSense RedEdge® sensor and were processed to ultimately obtain surface reflectance mosaics at 0.10 m ground spatial resolution. In this study, the potentiality of 24 variables (5 spectral bands, 15 vegetation indices and 4 biophysical parameters) are tested. The vegetation indices are selected for their potentiality to detect abnormal vegetation behavior in relation to stress or diseases. Among the biophysical parameters selected, three are directly linked to the leaf pigments content (chlorophyll, carotenoid and anthocyanin). The first step consisted in evaluating the performance of the 24 variables to separate symptomatic vine vegetation (FD or/and GTD) from asymptomatic vine vegetation using the performance indicators from the Receiver Operator Characteristic (ROC) Curve method (i.e., Area Under Curve or AUC, sensibility and specificity). The second step consisted in mapping the symptomatic vines (FD and/or GTD) at the scale of the field using the optimal threshold resulting from the ROC curve. Ultimately, the error between the level of infection predicted by the selected variables (proportion of symptomatic pixels by vine) and observed in the field (proportion of symptomatic leaves by vine) is calculated. The same methodology is applied to the three levels of analysis: by vineyard, by cultivar (Gamay, Fer Servadou) and by berry color (all red cultivars). At the vineyard and cultivar levels, the best variables selected varies. The AUC of the best vegetation indices and biophysical parameters varies from 0.84 to 0.95 for Case 1 and 0.74 to 0.90 for Case 2. At the berry color level, no variable is efficient in discriminating FD vines from GTD ones (Case 2). For Case 1, the best vegetation indices and biophysical parameter are Red Green Index (RGI)/ Green-Red Vegetation Index (GRVI) (based on the green and red spectral bands) and Car (linked to carotenoid content). These variables are more effective in mapping vines with a level of infection greater than 50%. However, at the scale of the field, we observe misclassified pixels linked to the presence of mixed pixels (shade, bare soil, inter-row vegetation and vine vegetation) and other factors of abnormal coloration (e.g., apoplectic vines).

Abstract Background and study aims Endoscopic ultrasound (EUS) may be a useful modality for disease assessment and risk stratification in ulcerative colitis. We assessed the reliability of a newly developed EUS index of inflammation called the EUS-Ulcerative Colitis (EUS-UC) score. Patients and methods The EUS-UC score components include total wall thickness, hyperemia, and depth of inflammation (DOI). Three blinded expert endosonographers assessed EUS videos of 58 patients with UC in triplicate. Intra- and inter-rater reliability of the hyperemia and DOI component scores were estimated using intra-class correlation coefficients (ICCs). Total wall thickness reliability estimates could not be assessed in this study. The ICCs were compared to the original indices from which they were derived. Results For hyperemia, the inter-class ICC was “moderate” at 0.556 (95 % CI = 0.434–0.651) and the intra class ICC was “almost perfect” at 0.884 (95 % CI = 0.835–0.920). The newly defined hyperemia score performed better than the original index from which is was derived. The DOI inter-class ICC was “fair” at 0.335 (95 % CI = 0.201–0.464), and the intra-class ICC was “substantial” at 0.732 (95 % CI = 0.642–0.802). The DOI reliability estimates were similar to the original index from which it was derived. Conclusions The hyperemia component of the EUS-UC score performed significantly better than the original index from which it was derived, but the reliability of the DOI component was suboptimal. Intra-class correlation was excellent for both components. The EUS-UC score is a promising instrument for assessment of UC and further validation is required.

Abstract Background Commonly used endoscopic indices in IBD lack ability to provide overall disease burden and severity, generate low inter-observer agreement, and demonstrate incomplete validation of some scores. We developed an endoscopic reporting tool, the Toronto IBD Global Endoscopic Reporting (TIGER) score for Crohn’s disease (CD) and ulcerative colitis (UC) patients. The aim of our study was to compare the usability and validity of the TIGER score against fecal calprotectin (FC), C-reactive protein (CRP) and IBD DISK score in CD patients. Methods A cohort of 60 CD patients participated in the study. Blinded IBD experts reviewed and graded ileocolonoscopy videos. In the validation phase, the TIGER score was compared to: (1) the Simple endoscopic Score for Crohn’s disease (SES-CD) as a reference standard and: (2) inflammatory biomarkers FC and CRP and (3) IBD Disk score. Results Inter-observer reliability per segment between reviewers was excellent: Interclass Correlation Coefficient (ICC)=0.94; [95%CI: 0.92–0.96]. For categorized TIGER score, lowest overall agreement was 96.6% [95%CI: 93.5–98.6] and lowest kappa 0.91 [95%CI: 0.84–0.98], reflecting excellent agreement. Overall agreement per segment between SES-CD and TIGER was 91% [95%CI: 84–95] with kappa coefficient 0.77 [95%CI: 0.63–0.91]. Per subject analysis for CD yielded overall agreement of 80% [95%CI: 64–91] and kappa coefficient 0.44 [95%CI: 0.14–0.75]. There was a significant correlation between TIGER and CRP (r s = .689, p < .0083), and TIGER and FC (r s = .687, p < .0001). In addition, there was significant correlation between TIGER and IBD Disk (r s = .613, p < .0001). Conclusion The TIGER score demonstrates significant correlation with FC, CRP and IBD disk score in Crohn’s disease patients and thus can be used as a reliable and simple endoscopic score for CD patients to capture overall endoscopic disease burden.

Per subject analysis for UC yielded overall agreement of 80% [95%CI: 64–91] and kappa coefficient 0.44 [95%CI: 0.14–0.75]. There was a significant correlation between TIGER and FC (r s = .794, p < .0001). There was a significant correlation between TIGER and IBD Disk (r s = .613, p < .0001). As expected, there was a lower correlation between TIGER score and CRP (r s = .309, p < .0850) in UC patients. Conclusion The TIGER endoscopic score demonstrates significant correlation with FC and IBD disk score in ulcerative colitis patients and thus can be used as a reliable and simple endoscopic score for UC patients to capture overall endoscopic disease burden.

"Activity of loggerhead turtles during the U-shaped dive: insights using angular velocity metrics." Endangered Species Research 45 (May 6, 2021): 1–12. http://dx.doi.org/10.3354/esr01125.
Full textAbstract:
Understanding the behavioural ecology of endangered taxa can inform conservation strategies. The activity budgets of the loggerhead turtle Caretta caretta are still poorly understood because many tracking methods show only horizontal displacement and ignore dives and associated behaviours. However, time-depth recorders have enabled researchers to identify flat, U-shaped dives (or type 1a dives) and these are conventionally labelled as resting dives on the seabed because they involve no vertical displacement of the animal. Video- and acceleration-based studies have demonstrated this is not always true. Focusing on sea turtles nesting on the Cabo Verde archipelago, we describe a new metric derived from magnetometer data, absolute angular velocity, that integrates indices of angular rotation in the horizontal plane to infer activity. Using this metric, we evaluated the variation in putative resting behaviours during the bottom phase of type 1a dives for 5 individuals over 13 to 17 d at sea during a single inter-nesting interval (over 75 turtle d in total). We defined absolute resting within the bottom phase of type 1a dives as periods with no discernible acceleration or angular movement. Whilst absolute resting constituted a significant proportion of each turtle’s time budget for this 1a dive type, turtles allocated 16-38% of their bottom time to activity, with many dives being episodic, comprised of intermittent bouts of rest and rotational activity. This implies that previously considered resting behaviours are complex and need to be accounted for in energy budgets, particularly since energy budgets may impact conservation strategies.

<p style="text-align: justify;"><strong>Aim:</strong> The purpose of this study was to determine if multispectral high spatial resolution airborne imagery could be used to segregate zones in vineyards to target fruit of highest quality for premium winemaking. We hypothesized that remotely sensed data would correlate with vine size and leaf water potential (ψ), as well as with yield and berry composition.</p><p style="text-align: justify;"><strong>Methods and results:</strong> Hypotheses were tested in a 10-ha Riesling vineyard [Thirty Bench Winemakers, Beamsville (Ontario)]. The vineyard was delineated using GPS and 519 vines were geo-referenced. Six sub-blocks were delineated for study. Four were identified based on vine canopy size (low, high) with remote sensing in 2005. Airborne images were collected with a four-band digital camera every 3-4 weeks over 3 seasons (2007-2009). Normalized difference vegetation index (NDVI) values (NDVI-red, green) and greenness ratio were calculated from the images. Single-leaf reflectance spectra were collected to compare vegetation indices (VIs) obtained from ground-based and airborne remote-sensing data. Soil moisture, leaf ψ, yield components, vine size, and fruit composition were also measured. Strong positive correlations were observed between VIs and vine size throughout the growing season. Vines with higher VIs during average to dry years had enhanced fruit maturity (higher °Brix and lower titratable acidity). Berry monoterpenes always had the same relationship with remote sensing variables regardless of weather conditions.</p><p style="text-align: justify;"><strong>Conclusions:</strong> Remote sensing images can assist in delineating vineyard zones where fruit will be of different maturity levels, or will have different concentrations of aroma compounds. Those zones could be considered as sub-blocks and processed separately to make wines that reflect those terroir differences. Strongest relationships between remotely sensed VIs and berry composition variables occurred when images were taken around veraison.</p><strong>Significance and impact of the study:</strong> Remote sensing may be effective to quantify spatial variation in grape flavour potential within vineyards, in addition to characteristics such as water status, yield, and vine size. This study was unique by employing remote sensing in cover-cropped vineyards and using protocols for excluding spectral reflectance contributed by inter-row vegetation.

Full textAbstract:
Abstract Objectives Endoscopic mucosal improvement is the gold standard for assessing treatment efficacy in clinical trials of Crohn’s disease. Current endoscopic indices are not routinely used in clinical practice. The lack of endoscopic information in large clinical registries limits their use for research. A quick, easy, and accurate method is needed for assessing mucosal improvement for clinicians in real-world practice. We developed and tested a novel simplified endoscopic mucosal assessment for Crohn’s disease (SEMA-CD). Methods We developed a 5-point scale for ranking endoscopic severity of ileum and colon based on Simple Endoscopic Score for Crohn’s disease (SES-CD). Central readers were trained to perform SES-CD and SEMA-CD. Pediatric patients with Crohn’s disease undergoing colonoscopy were enrolled. Video recordings of colonoscopies were de-identified and randomly assigned to blinded central readers. The SES-CD and SEMA-CD were scored for each video. The SES-CD was considered the validated standard for comparison. Correlation was assessed with Spearman rho, inter- and intrarater reliability with kappa statistics. Results Fifty-seven colonoscopies were read a total of 212 times. Correlation between SEMA-CD and SES-CD was strong (rho = 0.98, P < 0.0001). Inter-rater reliability for SEMA-CD was 0.80, and intrarater reliability was 0.83. Central readers rated SEMA-CD as easier than SES-CD. Conclusion The SEMA-CD accurately and reproducibly correlates with the standard SES-CD. Central readers viewed SEMA-CD as easier than SES-CD. Use of SEMA-CD in practice should enable collecting mucosal improvement information in large populations of patients. This will improve the quality of research that can be conducted in clinical registries. External validation is needed.

Full textAbstract:
The article is devoted to the study of the capabilities of the EG-2990Zi video gastroscope combined with the EPK-i7000 Pentax video processor in the process of comparative assessment of the effectiveness of using narrow-band video imaging with optical magnification in diagnosing certain diseases of upper gastrointestinal, namely, the esophagus, gaster, and duodenum. In particular, the method of comparative assessment of the mucous coat condition and morphological criteria in patients with Barrett's esophagus, as one of the serious complications of gastroesophageal reflux disease, is considered when performing narrow-band video imaging with optical magnification compared to a routine endoscopic examination technique. At the second stage, endoscopic indices and morphological diagnostic criteria in patients with ulcers and cicatricial deformity of the gaster and duodenum were compared. The final stage is connected with the study of the state of the mucous coat and morphological criteria in patients with polyps of the stomach and duodenum. The result of a comparative analysis of the findings obtained using these methods enables the early detection of changes in the mucous coat of the esophagus, preceding neoplastic ones when coinciding with the morphological conclusion in patients with the above diseases. The main points of scientific novelty include the following: a clear diagnostic algorithm has been first proposed for diseases of upper gastrointestinal diseases, taking into account the use of innovative technologies combined with a morphological study of biopsy material, which differs from routine endoscopic examination only in white light using a logical structure of study of the effectiveness of various endoscopic imaging visualization modes in terms of detailing of the micrograph and angioarchitecture of the mucous coat during the identification of spread and extent of manifestation of various chronic pathologies of the esophagus, gaster and duodenum; it has been proposed to assess the inter-relation between the data of endoscopic examinations and morphological criteria within the independent main and control groups, differing in the use of correlation analysis by the Spearman criterion and allowing to statistically substantiate the advantages of narrow-band imaging with hig

Full textAbstract:
Not all the time … but mostly … is the outcome of collaboration across the genres of ethnographic research, and visual and performing arts. In exploring renewed methodologies for social research Maggie sought to develop a methodological model (ethno-mimesis) rooted in feminist thought and practice, that represented in visual artistic forms the multiple standpoints of women working in prostitution. Ethno-mimesis is a combination of ethnographic research and the representation of this work in visual/artistic form. Introduced by a mutual friend in 1997 our collaborative work began with Sara reading and interpreting the ethnographic work with a view to developing a performance text, as an exemplar of ethno-mimesis. In the collaborative work presented here the hybrid texts that emerge are an outcome of the inter-relationship between ethnographic research and the re-presentation of women's life stories through live art forms – video, and two movement based performances. Through this work we hope to reach a wider audience, beyond academic communities, facilitating understanding, interpretation and maybe even action/praxis in relation to prostitution as a social issue. In representing ethnographic data in artistic form it is hoped that we can access a richer understanding of the complexities of women's lived experiences that can throw light on broader social structures and processes. Such hybrid work may also help audiences to see that women working in prostitution are ordinary women; and that ‘prostitutes’ are indices for all women.

Full textAbstract:
Les matériaux constitutifs des digues sont souvent des sables silteux dont le comportement mécanique peut manifester une « instabilité » à des états de contraintes situés bien avant la limite de plasticité de Mohr-Coulomb. Ce mécanisme de rupture pourrait expliquer plusieurs brèches dont l'occurrence n'a pas été attribuée aux mécanismes classiques de rupture de digues telle que l'érosion interne. L'objectif de cette thèse est de mieux comprendre, au regard de ce phénomène d'instabilité, le comportement mécanique d'un sable silteux provenant de la zone adjacente à une brèche de digue du Rhône lors de la crue de 2003, à l'aide d'essais triaxiaux.Les résultats sur le sable propre montrent que le matériau étudié est très sensible au phénomène d'instabilité. Ce dernier peut être prédit par une courbe d'instabilité reliant, au déclenchement de l'instabilité, le rapport des contraintes au paramètre d'état. L'analyse de ces résultats suggère qu'une forte contractance du matériau est la condition nécessaire pour que l'instabilité du sable lâche ait lieu et qu'une direction appropriée du vecteur d'incrément de contraintes est la condition suffisante.Les résultats sur les mélanges constitués du sable avec des fines montrent qu'un départ de fines, causé par exemple une érosion de type suffusion, favorise l'occurrence de l'instabilité dans les digues. Par ailleurs, ces résultats révèlent que l'indice des vides équivalent est un paramètre pertinent dans l'analyse du comportement du sable silteux. Le calcul de l'indice des vides équivalent nécessite la détermination du paramètre b pour lequel une nouvelle formule a été proposéeThe constitutive materials of dikes are often silty sands whose mechanical behavior can become unstable at stress states located well under the Mohr-Coulomb plasticity limit criterion. This failure mechanism could explain several dike breaches whose occurrence has not been assigned to conventional mechanisms of dike failure such as internal erosion. The objective of this thesis is to better understand, with respect to the instability phenomenon, the mechanical behavior of a silty sand which is collected in the area adjacent of a breach of the Rhone embankment dike during the flood of 2003, by means of triaxial tests.The test results obtained on clean sand show that this material is very sensitive to the instability phenomenon. The occurrence of the latter can be predicted by an instability curve relating, at the onset of instability, the stress ratio to the state parameter. The analysis of these results suggests that a strong contractiveness of the material is the necessary condition for instability of loose sand and an appropriate direction of stress increment vector is the sufficient condition.The test results obtained on mixtures of sand with fines show that a removal of fine particles caused by an erosion, such as suffusion for example, favors the occurrence of instability in the dikes. Moreover, these results indicate that the equivalent void ratio is a relevant parameter in analyzing the behavior of silty sand. The calculation of the equivalent void ratio requires the determination of the parameter b for which a new formula has been proposed

Full textAbstract:
In this fourth industrial revolution, knowledge transfer is essential among experienced academics for cross-fertilisation of ideas. Academics or colleagues in higher education institutions (HEIs) should harness and share their intuitive knowledge, skills, and experience for better service delivery. The rationale attributes to the decrease in skilled professionals in academia, technophobia, age, and language barriers. The issues of physical and mental ability, communication barrier, lack of trust, policies affirmation and organisational culture not supportive of knowledge transfer in HEIs were identified. A flair for things such as the consideration of who must capture new knowledge for organisational sustainability; suitable infrastructural facilities that can be used to gather, store and distribute information and knowledge; uncertainty of diverse economic and political influences; and limited budgetary allocation was believed to also affect knowledge transfer among academics. The qualitative research approach makes use of interpretive content/document analysis harvested from different databases to support the arguments regarding what, why and how knowledge transfer is central to every human endeavour. Findings indicate that inter-and intra-organisational knowledge transfer and organisational culture are the oil that lubricates organisational growth of academia. The study found that tacit to tacit type of knowledge, skills, and experiences were mostly transferred through communication through face-to-face discussions, online platforms, emails, and LinkedIn. Formal and informal processes of knowledge creation, application, peer-to-peer, and teamwork training approaches (coaching, mentorship, networking, and work shadows) and the use of certain tools (social and collaborative tools, video, chat, intranet, blog, posting, forum and mobile devices) were significant in this era of digital technologies. The study recommends succession planning for knowledge transfer, an attitude of trust, cooperation and teamwork, training, communication, and lifelong learning to enhance knowledge transfer among academics.

Full textAbstract:
In order to improve the undetectability, a lossless algorithm based on orthogonal vectors with limited distortion diffusion for 3D H.264 video is proposed in this paper. Inter-view distortion drift is avoided by embedding data into frames, which do not predict other views. Three conditions and pairs of coefficients are proposed to prevent intra-frame distortion diffusion. Several quantized discrete cosine transform coefficients are chosen from an embeddable luminance 4×4 block to construct a carrier vector, which is modified by an offset vector. When the carrier vector and the offset vector are orthogonal or near to be orthogonal, a data bit can be hidden. Experimental results indicate that the method is effective by enhancing peak signal-to-noise ratio with 7.5dB and reducing the Kullback-Leibler divergence with 0.07 at least. More than 1.7×1015 ways could be utilized for constructing the vectors, so it is more difficult for others to steal data.
