Growth and Income Poverty in Latin America and the Caribbean: Evidence from Household Surveys
No full textThis paper provides evidence on growth and income poverty in Latin American and the Caribbean. Results are obtained by processing microdata from household surveys of 18 LAC countries covering the 1990s and early 2000s. Over this period the LAC economies have experienced very heterogeneous patterns of growth and poverty changes. Most countries in the region have had a rather meager performance in terms of poverty reduction. Episodes of positive, significant and unambiguously pro-poor income growth have been rare in Latin America in the last 15 years.poverty, growth, inequality, pro-poor growth, Latin America.
Monitoring Sustainability Along Cultural Routes: The MED Sustainable Path and Cultural Route Model
No full textThe chapter describes the theoretical and methodological approach followed to develop the MED sustainable path and cultural route (MED S&C Path) model as a practical tool to monitor sustainable tourism development along cultural routes. In the framework of BEST MED (Beyond European Sustainable Tourism MED Path) project, the model aims at improving the management of cultural routes by assessing their sustainability level using a set of criteria and indicators. The implementation process of the model proposes a multi-stakeholder approach which contributes to higher levels of cooperation at local, regional, and transnational level, improving the governance of cultural routes. The MED S&C Path model responds to the concrete need of increasing the tools to measure cultural routes' social, economic, and environmental impact, in order to raise awareness among policy makers about their strategic role in sustainable local development, especially in rural and less-known areas
Human perception of image complexity: real scenes versus texture patches
No full textThe aim of this work is to study image complexity perception of real images. We conducted psycho-physical experiments where observers judged the complexity of different datasets of images on a web-based interface [1]. At the end of the test, observers indicated the main characteristics that guided their judgements. The databases differed in the type of visual stimuli used: images representing real scenes and/or texture patches. For real scenes the most relevant criteria used were quantity of objects, details and colors, while for texture patches they were regularity and understandability. Several criteria are adopted simultaneously, confirming the multidimensional aspect of complexity found in the literature [2]. To process the subjective data we applied z-scores and outlier removal. The mean scores are then correlated with different visual features. We considered features based on spatial, color and frequency properties that can be associated to bottom-up processes. To take into account top-down effects like understandability we included a memorability index [3]. We propose an image complexity measure where the features are linearly combined. The optimal weighting coefficients are those that best fit the subjective data and depend on the type of stimuli considered. Our measure, properly tuned, can predict complexity perception of different kind of images, outperforming the single visual features. From our investigation two aspects of image complexity can be underlined: many different perceptual properties are involved and their relative influence depends on the type of stimuli. These considerations are supported by both our computational proposal and the verbal description analysis.

Diagnosis: Elacatinus pridisi n. sp. differs from its congeners of the Horsti Complex (sensu Böhlke & Robins 1968) that have a pale stripe extending from the eye to the caudalfin base by the following combination of characters: dark longitudinal stripe wide, reaching lower abdomen and base of anal fin (vs. never reaching abdomen or base of anal fin in all other species); pectoralfin rays typically 18 (vs. typically 17 in E. randalli and E. figaro and typically 16 in E. atronasum (Böhlke & Robins)); analfin rays typically 11 (vs. typically 10 in E. figaro); oval spot present on snout (vs. no spot in E. atronasum and E. horsti (Böhlke & Robins), a "V"shaped spot in E. prochilos (Böhlke & Robins), and a medial bar in E. xanthiprora (Böhlke & Robins), E. louisae (Böhlke & Robins) and E. lori Colin). Description. Morphometrics of holotype and four largest paratype specimens (21.0– 28.4 mm SL) as percent of standard length (mean): head length 22.5–24.7 (23.3); snout length 3.7–4.2 (3.9); eye diameter 6.0– 6.8 (6.3); postorbital distance 13.5–14.9 (14.3); depth of body at dorsal fin origin 15.5–16.1 (15.7); least depth of caudal peduncle 11.0– 12.3 (11.4); upper jaw length 6.5–8.4 (7.6); pectoral fin length 19.3–20.8 (20.0); ventral fin length 17.3–18.3 (17.7); caudal fin length 17.1 –20.0(17.7); maximum width of color stripe 5.1–6.4 (5.8). Body naked, elongate. Mouth subterminal, no canine teeth on jaws. Dorsal fin without elongated anterior spines. Caudal fin rounded and ventral fin cup complete. Dorsalfin rays VII, 11–12 (modally 12); Analfin rays 11; pectoralfin rays 17–18 (modally 18). Color pattern: a pale (bright yellow in life) stripe extending from the eye to the caudalfin base, stripe narrower close to eye (more uniform in juveniles); a pale (bright yellow in life) oval spot present on snout; dark longitudinal stripe wide, reaching lower abdomen and base of anal fin; all finrays except caudal black or dusky. Remarks: Elacatinus pridisi differs from the other two Brazilian species of the genus by its higher number of pectoralfin rays and by its wider extension of its dark pigmentation, reaching the abdomen as well as dorsal and analfin rays (Figure 3). Distribution: The new species was collected only from Trindade Island (20 ° 30 'S, 29 ° 20 'W), a volcanic formation off southeastern Brazil (Figure 4) and is probably endemic to the TrindadeMartin Vaz oceanic insular complex (Figure 5). Etymology: The name pridisi is used in honor of the Brazilian Navy First District (Primeiro Distrito Naval, Marinha do Brasil "PRIDIS"), in recognition for the impeccable logistic support provided during the authors´field trips to the type locality. Natural History: Elacatinus pridisi was recorded at depths ranging from 3 to 30 m over crustose algal reefs and rocky bottoms around Trindade Island. The new species performs cleaning activities during most of its lifecycle, and has, at least, 21 different client species (Gasparini & Floeter, 2001).Published as part of Guimarães, Ricardo Z.

Differential expression of circular RNAs in a mouse model of autism spectrum disorders
No full textAutism spectrum disorder (ASD) comprises a heterogeneous group of pervasive developmental disabilities characterized by compromised social interactions and communication skills, and by restrictive and repetitive behaviors. Emerging evidence suggests the involvement of non-coding RNAs (ncRNAs) in the pathophysiology of ASD. circRNAs arisen in the last decades as a novel class of ncRNAs and recent reports have shown their implication in the pathogenesis of several human neurological diseases. circRNAs are endogenous stable molecules, characterized by a covalently closed structure resulting from a backpslicing reaction. They are evolutionary conserved, abundant and significantly enriched in the brain. Although the biological function is still unknown, specific circRNAs are regulated by neuronal activity and have been implicated in plasticity mechanisms.
In this study, we present the expression profile of circRNAs in the hippocampus of BTBR T + tf/J (BTBR) mouse model for Autism Spectrum Disorder (ASD), compared to age-matched C57BL/6J (B6) mice. We identified several circRNAs whose expression is consistently altered, and 12 circRNAs and their corresponding linear counterparts were validated by RT-qPCR analysis. The ASD-related circCdh9 and circRmst have been further characterized in terms of molecular structure and expression. To evaluate their functional role in a physiological context, we characterized their expression during mouse development, neuronal differentiation and homeostatic plasticity. Interestingly, our results suggest a possible involvement of circCdh9 and circRmst in brain development and neuronal differentiation. Moreover, to comprehensively investigate the transcriptomic profile of the hippocampus of BTBR mice, we analyzed the gene and miRNA expression patterns. We performed enrichment analysis of BTBR differentially expressed RNA species and found interesting biological and molecular pathways associated to ASD phenotype. Lastly, we compared the circRNAs and gene expression profiles and we identified 6 genes highly modulated as circular and linear isoforms, indicative of a low correlation in the expression of circRNAs and their host genes.
In conclusion, our study has identified and analyzed differentially expressed circRNAs in the BTBR hippocampus, and we deepen characterized two ASD-associated circRNAs candidates. By integrating the circRNAs and gene expression profiles, we found a coregulation in the expression of specific genes ASD related. Moreover, we explored for the first time the miRNA expression profile in the hippocampus of BTBR mice, and we found 18 significantly modulated miRNAs. Functional studies are in progress to shed more light on the physiological function of circCdh9 and circRmst and their putative role in the pathophysiology of ASD
