Uniformly Distributed Measures have Big Pieces of Lipschitz Graphs locally

The study of uniformly distributed measures was crucial in Preiss' proof of his theorem on rectifiability of measures with positive density. It is known that the support of a uniformly distributed measure is an analytic variety. In this paper, we provide quantitative information on the rectifiability of this variety. Tolsa had already shown that $n$-uniform measures have Big Pieces of Lipschitz Graphs(BPLG) . Here, we prove that a uniformly distributed measure has BPLG locally

Postmodern narrative in Kurt Vonneguts Slaughterhouse-Five

This article explores Kurt Vonnegut’s Slaughterhouse-Five (1969) as a postmodern critique of modern literary modes. As a novel recapitulating within itself a postmodern relative perspective of reality, it elucidates one aspect of postmodernism, that of literary experimentation. Vonnegut experiments with the narrator,setting and characters of the novel to provide a fictional critique of the literary exhaustion prevailing in modern literary modes. Experimentation is thus remedial replenishment for such exhaustion through authorial metafictional intrusion into the text. Accordingly, the article uses Patricia Waugh, Gérard Genette and Mikhail Bakhtin’s narrative theory to examine the experimental technique in the novel. What makes the majority of metafictional style unique is not only its presence in the novel, but also its conflated depiction of the American individual’s suffering after the Second World War.For this later style, the self-justifying manner in the novel extrapolates textual dialogic relations to accentuate the author’s critical voice. Such voice originates in the main narrative point of view in the text and is known as focalization

Customer Perceptions of Service Quality in Luxury Hotels in Petra and Aqaba, Jordan: An Exploratory Study

The aim of the study is to assess customers perception of service quality in luxury hotels, in both, Petra (The iconic tourist attraction), and Aqaba (The commercial capital) on the Red Sea in Jordan and to help the hotel management identify how guest perceive the services and compare their performance against clients expectation. The study used a survey and interviews to accumulate information using SPSS version 20.0 for data analysis. The study sample consists of 271 participants of hotel guests at four- and five-star hotels in Petra and Aqaba. Findings results show that for responses relating to front office, room service, and in-house cafe/restaurant, the importance score is statistically significant to and higher than the performance rating. Overall, the results indicate a significant difference in guest expectations and actual experiences, thus highlighting managerial implications. The current study cannot claim to be wholly conclusive as it is limited to a small sample size from only two cities of Jordan. From a practitioner’s perspective, the study provides an opportunity to recognize, in ranking order, features that are considered important by the guests staying in luxury hotels of Petra and Aqaba, as well as to identify the areas of disparity in service quality. It is observed that this is a significant study regards to its contribution to the literature and hotel managers who plan to improve their performance and competitiveness through guest satisfaction

Markedly Divergent Tree Assemblage Responses to Tropical Forest Loss and Fragmentation across a Strong Seasonality Gradient

We examine the effects of forest fragmentation on the structure and composition of tree assemblages within three seasonal and aseasonal forest types of southern Brazil, including evergreen, Araucaria, and deciduous forests. We sampled three southernmost Atlantic Forest landscapes, including the largest continuous forest protected areas within each forest type. Tree assemblages in each forest type were sampled within 10 plots of 0.1 ha in both continuous forests and 10 adjacent forest fragments. All trees within each plot were assigned to trait categories describing their regeneration strategy, vertical stratification, seed-dispersal mode, seed size, and wood density. We detected differences among both forest types and landscape contexts in terms of overall tree species richness, and the density and species richness of different functional groups in terms of regeneration strategy, seed dispersal mode and woody density. Overall, evergreen forest fragments exhibited the largest deviations from continuous forest plots in assemblage structure. Evergreen, Araucaria and deciduous forests diverge in the functional composition of tree floras, particularly in relation to regeneration strategy and stress tolerance. By supporting a more diversified light-demanding and stress-tolerant flora with reduced richness and abundance of shade-tolerant, old-growth species, both deciduous and Araucaria forest tree assemblages are more intrinsically resilient to contemporary human-disturbances, including fragmentation-induced edge effects, in terms of species erosion and functional shifts. We suggest that these intrinsic differences in the direction and magnitude of responses to changes in landscape structure between forest types should guide a wide range of conservation strategies in restoring fragmented tropical forest landscapes worldwide

Foram elaborados para a área em estudo, arquivos digitais georreferenciados, relativos aos temas: limite municipal, áreas urbanizadas, infra-estrutura viária, rede de drenagem, altimetria, cobertura vegetal natural, uso agrícola do solo e zoneamento. Os resultados obtidos evidenciaram que o município apresenta quatro regiões com aspectos distintos, as quais foram identificadas como regiões agroecológicas, de acordo com o fator que mais se destacou em cada área

De novo erythroleukemia chromosome features include multiple rearrangements, with special involvement of chromosomes 11 and 19

Erythroid leukemia (ERL or AML-M6) is an uncommon subtype of acute myeloid leukemia, the clinical, morphological, and genetic behavior of which needs further characterization. We analyzed a homogeneous group of 23 de novo AML-M6 patients whose bone marrow cells showed complex karyotypes. We also analyzed eight leukemia cell lines with erythroid phenotype, performing detailed molecular cytogenetic analyses, including spectral karyotyping (SKY) in all samples. The main features are: (1) A majority of patients (56%) had hypodiploidy. Loss of genetic material was the most common genetic change, especially monosomies of chromosome 7 or 18, and deletions of chromosome arm 5q. Taken together, 87% of the cases displayed aberrations involving chromosome 5 or 8. (2) We describe a novel, cryptic, and recurrent translocation, t(11;19)(p11.2;q13.1). Another translocation, t(12;21)(p11.2;q11.2), was found to be recurrent in a patient with ERL and in the K562 cell line. (3) MLL gene rearrangements were detected in 20% of cases (three translocations and three amplifications) and, overall, we defined 52 rearrangements (excluding deletions) with a mean of 2.3 translocations per patient. (4) Of the structural aberrations, 21% involved chromosomes 11 and 19. Most of the rearrangements were unbalanced; only 13 reciprocal translocations were observed. The general picture of chromosomal aberrations in cell lines did not reflect what occurred in patient samples. However, both primary samples and cell lines shared three common breakpoints at 19q13.1, 20q11.2, and 21q11.2. This is the first molecular cytogenetic description of the karyotype abnormalities present in patients with ERL. It should assist in the identification of genes involved in erythroleukemogenesis

Medical tourism’s impact for health systems: A study from three Asian countries

Medical tourism is a growing phenomenon with policy implications for health systems, particularly of destination countries. Private actors and governments in Southeast Asia are promoting the medical tourist industry, but the potential impact on health systems, particularly in terms of equity in access and availability for local consumers, is unclear. This article presents a conceptual framework that outlines the policy implications of medical tourism’s growth for health systems, illustration on the cases of Thailand, Singapore and Malaysia, three provincial centres for medical tourism, via an extensive review of academic and grey literature. Variables for further analysis of the potential impact of medical tourism on health systems are also identified. The framework can provide a basis for empirical, in country studies weighing the benefits and disadvantages of medical tourism for health systems. The policy implications described are of particular relevance for policymakers and industry practitioners in other Southeast Asian countries with similar health systems where governments have expressed interest in facilitating the growing of the medical tourist industry

A phase 1b/2b multicenter study of oral panobinostat plus azacitidine in adults with MDS, CMML or AML with less than or equal to 30% blasts

Treatment with azacitidine (AZA), a demethylating agent, prolonged overall survival (OS) vs conventional care in patients with higher-risk myelodysplastic syndromes (MDS). As median survival with monotherapy is <2 years, novel agents are needed to improve outcomes. This phase 1b/2b trial (n=113) was designed to determine the maximum tolerated dose (MTD) or recommended phase 2 dose (RP2D) of panobinostat (PAN)+AZA (phase 1b) and evaluate the early efficacy and safety of PAN+AZA vs AZA monotherapy (phase 2b) in patients with higher-risk MDS, chronic myelomonocytic leukemia or oligoblastic acute myeloid leukemia with <30% blasts. The MTD was not reached; the RP2D was PAN 30 mg plus AZA 75 mg/m2. More patients receiving PAN+AZA achieved a composite complete response ([CR)+morphologic CR with incomplete blood count+bone marrow CR (27.5% (95% CI, 14.6–43.9%)) vs AZA (14.3% (5.4–28.5%)). However, no significant difference was observed in the 1-year OS rate (PAN+AZA, 60% (50–80%); AZA, 70% (50–80%)) or time to progression (PAN+AZA, 70% (40–90%); AZA, 70% (40–80%)). More grade 3/4 adverse events (97.4 vs 81.0%) and on-treatment deaths (13.2 vs 4.8%) occurred with PAN+AZA. Further dose or schedule optimization may improve the risk/benefit profile of this regimen
