A pre-post test evaluation of the impact of the PELICAN MDT-TME Development Programme on the working lives of colorectal cancer team members
No full textBackground: the PELICAN Multidisciplinary Team Total Mesorectal Excision (MDT-TME) Development Programme aimed to improve clinical outcomes for rectal cancer by educating colorectal cancer teams in precision surgery and related aspects of multidisciplinary care. The Programme reached almost all colorectal cancer teams across England. We took the opportunity to assess the impact of participating in this novel team-based Development Programme on the working lives of colorectal cancer team members.Methods: the impact of participating in the programme on team members' self-reported job stress, job satisfaction and team performance was assessed in a pre-post course study. 333/568 (59%) team members, from the 75 multidisciplinary teams who attended the final year of the Programme, completed questionnaires pre-course, and 6-8 weeks post-course.Results: across all team members, the main sources of job satisfaction related to working in multidisciplinary teams; whilst feeling overloaded was the main source of job stress. Surgeons and clinical nurse specialists reported higher levels of job satisfaction than team members who do not provide direct patient care, whilst MDT coordinators reported the lowest levels of job satisfaction and job stress. Both job stress and satisfaction decreased after participating in the Programme for all team members. There was a small improvement in team performance.Conclusions: participation in the Development Programme had a mixed impact on the working lives of team members in the immediate aftermath of attending. The decrease in team members' job stress may reflect the improved knowledge and skills conferred by the Programme. The decrease in job satisfaction may be the consequence of being unable to apply these skills immediately in clinical practice because of a lack of required infrastructure and/or equipment. In addition, whilst the Programme raised awareness of the challenges of teamworking, a greater focus on tackling these issues may have improved working lives furthe

We evaluated autonomic cardiovascular regulation in subjects with polycythemia and chronic mountain sickness (CMS) and tested the hypothesis that an increase in arterial oxygen saturation has a beneficial effect on arterial baroreflex sensitivity in these subjects. Ten Andean natives with a Hct >65% and 10 natives with a Hct 65% showed an increased incidence of CMS compared with subjects with Hct <60%. Spontaneous baroreflex sensitivity was significantly lower in subjects with high Hct compared with the control group. The effects of supplemental oxygen or modification of the breathing pattern on autonomic function were as follows: 1) heart rate decreased significantly after both maneuvers in both groups, and 2) spontaneous baroreflex sensitivity increased significantly in subjects with high Hct and did not differ from subjects with low Hct. Temporary slow-frequency breathing may provide a beneficial effect on the autonomic cardiovascular function in high-altitude natives with CMS
A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc

Pelvic and anal fins lighter than remaining fins. Dorsal and caudal fins darker than pectoral fin. Adipose fin with dark distal margin.</p> <p> <b>Distribution.</b> <i>Schizodon paucisquamis</i> is only known from the rio Arinos, a tributary of the rio Juruena, rio Tapajós basin, Mato Grosso state, Brazil (Fig. 3).</p> <p> <b>Etymology.</b> The species epithet is an adjectivized noun combining the Latin <i>paucus</i>, few, and <i>squama</i>, referring to the reduced circumpeduncular squamation of caudal peduncle that is a distinguishing feature of the species.</p> <p> <b>Remarks</b>. The color pattern of the new species is basically the same as that of <i>Schizodon fasciatus</i> and <i>S. trivittatus</i>, which, as several other species of the genus, present four transversal blotches located in a similar position of the body. However, in large specimens (over 300 mm SL), the caudal peduncle blotch of the new species has a unique feature among congeners, due to its circular shape, slightly larger size than the eye, and intense black pigmentation. This unique feature, however, can only be used to distinguish relatively large-sized (larger than 250 mm SL) individuals. Smaller-sized paratypes (smaller than 250 mm SL) have the caudal peduncle blotch proportionally smaller, although still relatively large and quadrangular-shaped.</p> <p> <i>Schizodon paucisquamis</i> is only known from the rio Arinos, at its lower to middle stretches. The rio Arinos is a tributary of the rio Juruena, which joins the rio Teles Pires forming the rio Tapajós, one of the larger tributaries of the Amazon basin. Both the rio Arinos below Porto dos Gaúchos and the rio Juruena have rapids in their courses, which may have represented, over time, barriers to the free dispersion of some fish species. Thus, <i>S. paucisquamis</i> may represent an endemic species to the rio Arinos basin, or at least from the rio Juruena basin. The hypothesis of endemism of the species to this portion of the rio Tapajós basin is reinforced by the fact that many fish inventories have been carried out in this river basin in recent decades, and no specimens of this large species have been collected, except in the rio Arinos.</p> <p> <b>Comparative material examined.</b> All from Brazil except if otherwise noted. <i>Schizodon altoparanae</i>: MZUSP 41102, holotype, 282.0 mm SL, Mato Grosso do Sul, rio Paraná at Jupiá; MZUSP 41103 to 41120, paratypes, 28, 138.3–232.1 same locality as holotype. <i>Schizodon borellii:</i> MZUSP 2908, 1, 255.0 mm SL, Mato Grosso do Sul, Coxim, Rio Piquiri; MZUSP 62715, 1, 223.0 mm SL, Mato Grosso, Cuiabá, mouth of Varadouro; MZUSP 41146, 2, 290.0–298.0 mm SL, Mato Grosso, Cuiabá, Rio Coxipó da Ponte, São Gonçalo. <i>Schizodon corti</i>: USNM 121300, 1, 257.0 mm SL, holotype of <i>S. fasciatus corti</i>, Venezuela, rio Palmar, near Totuma, Lake Maracaibo basin. <i>Schizodon dissimilis</i>: MCZ 19383, lectotype, 264.6 mm SL, Piauí, rio Puty (= Poti), tributary of rio Parnaíba; MZUSP 55143, 4, 196.0–220.0 mm SL, rio Jaguaribe; MZUSP 55144, 1, 155.0 mm SL, Lima Campos, rio Jaguaribe, ribeirão São João. <i>Schizodon fasciatus</i>: MZUSP 20972, 15, 170.0–295.0 mm SL, Amazonas, Fonte Boa, Paraná of Iupiá; MZUSP 7518, 5, 110.0–130.0 mm SL, Amazonas, Paraná de Urucará, Urucará; MZUSP 62720, 5, 115.0–240.0 mm SL, Amazonas, Lago Castro, mouth of rio Purus. <i>Schizodon isognathus</i>: MZUSP 4397, 1, 307.0 mm SL, Brazil, Mato Grosso, rio Cuiabá, Santo Antonio do Leverger; MZUSP 36719, 1, 176.0 mm SL, Itiquira, Rio Piquiri, Porto Chinelo. <i>Schizodon jacuiensis</i>: MZUSP 38864, paratype, 111.0 mm SL, Rio Grande do Sul, Porto Alegre, rio Guaíba, Morro do Sabiá. <i>Schizodon knerii</i>: MZUSP 94051, 4, 75.1–86.8 mm SL, Bahia, rio Formoso, tributary of the rio Corrente; MZUSP 95159, 2, 155.0–167.0 mm SL, Minas Gerais, Três Marias dam, rio São Francisco. <i>Schizodon nasutus</i>: MZUSP 2023, 5, 87.0– 100.8 mm SL, São Paulo, rio Piracicaba, Piracicaba; MZUSP 42844, 17, 96.0–206.0 mm SL), São Paulo, rio Paraná, Ilha Solteira. <i>Schizodon platae</i>: MCZ 833, holotype, not measured, Argentina, Rosario, La Plata; MZUSP 47691, 1, 102.0 mm SL, Argentina, rio de La Plata, Buenos Aires. <i>Schizodon rostratus</i>: MCZ 19380, holotype, 180.0 mm SL, Piauí, rio Poti, tributary of Rio Parnaíba, Terezina; MCZ 69542, 4, 172.0–185.0 mm SL, Piauí, rio Poti, tributary of rio Parnaíba at Terezina. <i>Schizodon scotorhabdotus</i>: MZUSP 27969, paratypes, 3, 83.0–148.0 mm SL, Venezuela, caño to W of road from Calabozo to San Fernando, about 35 km to S of Masaquara farm (Caño Falcon). <i>Schizodon trivittatus</i>: MZUSP 115362, holotype, 285.0 mm SL, Mato Grosso, São José do Couto, rio Culuene; MZUSP 36835, 3, 149.0–252.0 mm SL, Pará, Altamira, rio Xingu, Cachoeira do Espelho. <i>Schizodon vittatus</i>: MZUSP 21334, 3, 173.0–192.0 mm SL, Pará, Tucuruí, rio Tocantins.

Parámetros de avaliação para projetos com melhor aproveitamento de uso
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-Graduação em ArquiteturaNa atualidade a totalidade de projetos habitacionais parte do principio absurdo do mínimo espaço para reduzir os custos da obra em lugar do utilizar um conceito do espaço necessário. Quase nenhum destes projetos leva em consideração o tamanho do mobiliário disponível no mercado. Isto cria uma incompatibilidade entre a necessidade espacial do usuário e a área disponível nas habitações de interesse social. Os resultados de uma construção com estas falhas entre outros são: O aumento dos custos para o morador que deve ampliar sua casa para poder utilizar o espaço com algo de conforto. A perda de flexibilidade de uso já que o espaço não permite variações no arranjo espacial. As habitações que não têm o equipamento necessário para sua utilização devido à falta de espaço para colocar o mobiliário. O congestionamento visual devido à aglomeração de móveis dentro de um cômodo criando desorganização e desconforto. A perda da privacidade pela carência de um espaço próprio. Os dormitórios sem utilidade durante o dia, que ficam lotados a noite. Como uma possível solução se propôs o conceito de um painel mobiliário o qual deveria contribuir com a facilidade de construção, montagem e pré-fabricação de um imóvel como alternativas para diminuir custos. Ao mesmo tempo este painel conteria o mobiliário necessário para a utilização dos diferentes cômodos e assim aproveitar ao máximo o incipiente espaço em projetos de habitação de interesse social. A fundamentação teórica deste painel foi realizada por meio de pesquisas sobre propostas de habitação social e projetos arquitetônicos que atendessem a princípios de produtos industrializados, assim como o levantamento dos problemas mencionados anteriormente. A realização prática se desenvolveu por meio de uma tabela que funciona como checklist e avaliam o conforto e habitabilidade destes projetos por meio da aplicação dos conceitos de flexibilidade, adaptabilidade e privacidade. Foi realizado também um levantamento de produtos existentes no mercado internacional que apresentam soluções inovadoras para espaços reduzidos tanto pela variedade de funções que o mesmo permite quanto pelas propostas de aproveitamento de espaço no transcurso do dia. Para testar tanto a tabela quanto a aplicabilidade do mobiliário pesquisado se utilizou como estudo de caso o protótipo desenvolvido pela ARQ-UFSC em colaboração com a empresa Battistella
