O Papel do Sector Privado para a Sociedade da Informação em Cabo Verde Estudo de Caso das Empresas das TIC

A filosofia de uma Sociedade da Informação forçou a transformação das sociedades modernas devido à massificação do uso das Tecnologias da Informação e Comunicação (TIC) e da internet, trazendo várias vantagens a nível político, económico e social. Cabo Verde é um exemplo dessa transformação, onde o uso dessas TIC despoletou o aparecimento de várias empresas do sector privado das TIC. Sendo, o sector privado das TIC ́s um tema muito relevante, tem que ser lembrado e discutido. Não só pela importância do uso das Tecnologias da Informação e Comunicações (TIC ́s) que hoje em dia são cruciais, mas também pela participação e a inclusão de todos, como um dos maiores desafios existentes na Sociedade sem esquecer o factor sensibilização para um maior engajamento nas novas tecnologias. Torna-se imprescindível a participação de todos. Neste trabalho monográfico procurou-se descrever alguns aspectos considerados importantes para o estudo, onde fez-se uma breve discrição do país, o uso da Internet e o percurso das TIC, ressaltando a função dos agentes promotores da Sociedade da Informação (Estado, sector privado, sociedade civil, organizações não governamentais) tal como o ensino, banca, seguradoras, agências de viagens e aprofunda o papel do Sector privado das TIC ́s, possibilitando a estes uma melhor visão das novas tecnologias e até mesmo de oportunidades contribuindo para uma melhoria da nação. Ao longo deste trabalho mostrou-se, de forma objectiva, a situação de Cabo Verde em relação à Sociedade da Informação, tendo como finalidade primordial mostrar o contributo, as dificuldades e/ou os constrangimentos que o sector privado das TIC`s enfrenta no processo que é a construção da Sociedade da Informação.

Organizações do Terceiro Sector: Estratégia para a sustentabilidade dos projectos sociais das ONG’s sedeadas no Concelho da Praia

As Organizações Não-governamentais que fazem parte do Terceiro Sector, vem se multiplicando no país, porém o grau de estruturação, capacidade de actuação e mobilização para a participação continua sendo fraco. Enfrentando, no quotidiano o problema da sustentabilidade dos seus projectos sociais. Diante desta situação, o presente trabalho monográfico, cujo tema é “Organizações do Terceiro Sector: estratégia para a sustentabilidade dos projectos sociais das ONG’s sedeadas no Concelho da Praia”, objectiva identificar e analisar as estratégias básicas utilizadas para a sustentabilidade dos seus projectos sociais. A realização da pesquisa teve duas partes: na primeira parte fazemos a pesquisa bibliográfica do tipo exploratório, consultando várias fontes bibliográficas que tivemos o cuidado de citar ao longo da pesquisa, com vista a permitir a consolidação da base teórica. E, na segunda parte realizamos a pesquisa no terreno do tipo descritivo, no qual aplicamos questionário a 25 ONG’s, complementando com um estudo de caso à ONG Fundação Infância Feliz ( FIF ) .A análise dos dados e informações obtidas permitiu-nos concluir que, as ONG’s deste concelho utilizam três estratégias básicas: ( i ) os pré-requisitos organizacionais, pois cerca de 90% das ONG’s se encontram enquadradas juridicamente e têm a sua missão e área de actuação especificadas; Ainda, mais de 90% já desenvolvem o processo de comunicação, tanto com os seus beneficiários como nas Mídias, e possuem recursos humanos qualificados, sendo que em 88% das ONG’s os seus técnicos tem formação superior; ( ii ) o projecto de captação de recursos, visto que cerca de 71% elabora-o sempre, e também ( iii ) as parcerias, pois todas as ONG’s inquiridas já estabeleceram parcerias com outras instituições, sendo que 91,7% com o Governo.

Vertebral microarchitecture and fragility fracture in men: a TBS study.

INTRODUCTION: Although osteoporosis is considered a disease of women, 25% of the individuals with osteoporosis are men. BMD measurement by DXA is the gold standard used to diagnose osteoporosis and assess fracture risk. Nevertheless, BMD does not take into account alterations of microarchitecture. TBS is an index of bone microarchitecture extracted from the spine DXA. Previous studies have reported the ability of the spine TBS to predict osteoporotic fractures in women. This is the first case-controlled study in men to evaluate the potential diagnostic value of TBS as a complement to bone mineral density (BMD), by comparing men with and without fractures. METHODS: To be eligible for this study, subjects had to be non-Hispanic US white men aged 40 and older. Furthermore, subjects were excluded if they have or have had previously any treatment or illness that may influence bone metabolism. Fractured subjects were included if the presence of at least one fracture was confirmed. Cases were matched for age (±3 years) and BMD (±0.04 g/cm(2)) with three controls. BMD and TBS were first retrospectively evaluated at AP spine (L1-L4) with a Prodigy densitometer (GE-Lunar, Madison, USA) and TBS iNsight® (Med-Imaps, France) in Lausanne University Hospital blinded from clinical outcome. Inter-group comparisons were undertaken using Student's t-tests or Wilcoxon signed rank tests. Odds ratios were calculated per one standard deviation decrease as well as areas under the receiver operating curve (AUC). RESULTS: After applying inclusion/exclusion criteria, a group of 180 male subjects was obtained. This group consists of 45 fractured subjects (age=63.3±12.6 years, BMI=27.1±4.2 kg/m(2)) and 135 control subjects (age=62.9±11.9 years, BMI=26.7±3.9 kg/m(2)) matched for age (p=0.86) and BMD (p=0.20). A weak correlation was obtained between TBS and BMD and between TBS and BMI (r=0.27 and r=-0.28, respectively, p<0.01). Subjects with fracture have a significant lower TBS compared to control subjects (p=0.013), whereas no differences were obtained for BMI, height and weight (p>0.10). TBS OR per standard deviation is 1.55 [1.09-2.20] for all fracture type. When considering vertebral fracture only TBS OR reached 2.07 [1.14-3.74]. CONCLUSION: This study showed the potential use of TBS in men. TBS revealed a significant difference between fractured and age- and spine BMD-matched nonfractured subjects. These results are consistent with those previously reported on for men of other nationalities.

Evaluation Of "Safe" Trabeculectomy Versus "Safe" Phacotrabeculectomy

Purpose: To evaluate the safety and efficacy of "safe" trabeculectomy (ST) versus "safe" phacotrabeculectomy (SPT).Methods: This study included 72 eyes with medically uncontrolled chronic glaucoma who underwent fornix based trabeculectomy with adjustable/releasable sutures and intraoperative mitomycin C ± phacoemulsification. 36 eyes underwent SPT and 36 eyes had ST. There was no difference between groups for age, intraocular pressure (IOP), diagnosis and gender. Subconjunctival antimetabolite injections and bleb needlings were administered according to bleb vascularity and IOP trends. Main outcome measures were: success rate (definition: IOP≤21mmHg and 20% IOP reduction); number of antimetabolite injections; bleb needlings; glaucoma medications and complications.Results: Mean age (SPT vs ST) was 72.7±12.1 years vs 72.3±12.9 years; p=0.44. Mean preoperative IOP was 24.5±8.8 mmHg vs 24.3±8.2 mmHg; p=0.46. Postoperative IOP was 13.1±4.5mmHg vs 12.4±3.2; p=0.24. Ninety percent of both groups required at least one suture removal. There was no statistically significant difference in success rate between groups, 80% vs 83%; number of eyes requiring antimetabolite injections was 22 eyes (mean 3.2 per eye) vs 23 eyes (mean 2.6 per eye, p=0.24); bleb needlings was performed in 16 eyes (mean 2.5 per eye) vs in 11 eyes (mean 2.0 per eye, p=0.15). The number of eyes restarting glaucoma medications was 5 vs 4. Minor complications were infrequent in both groups, 9 vs 10 eyes.Conclusions: The success and complications rates were similar between groups. The number of postoperative interventions required was slightly greater in the SPT group (not statistically significant). SPT is a safe procedure for patients with coexistent glaucoma and cataract and produces similar IOP-lowering to safe trabeculectomy.

Lire l'oral : pour une typologie linguistique des représentations écrites de l'oralité (le cas du français)

Cette thèse propose de passer en revue les modalités de la représentation écrite de l'oralité en français. La pratique littéraire constitue le matériau et l'horizon de la théorisation. La problématique - comment l'écrit représente-t-il l'oral ? - est d'abord située et reformulée dans le cadre de la linguistique de la parole (I). Les rapports entre oralité et scripturalité sont ensuite étudiés sous trois angles. L'angle biotechnologique compare la matérialité et l'affordance des signaux graphiques et des signaux acoustiques (II 1). L'examen sémiotique reconnaît dans le français écrit un système dit phonographique dont la fonction est de représenter l'expression des signes du français oral. Sont analysées alors les relations entre les systèmes de signes impliqués, la diversité des actualisations possibles du système phonographique (effets d'écoute), ainsi que diverses sémiotiques analogiques (II 2). On étudie ensuite le rôle de la prosodie dans la lecture. La position adoptée est la suivante : bien qu'elle soit facultative dans l'activité de lecture, la prosodie est spécialement sollicitée par des écrits qu'on peut caractériser linguistiquement. L'interprétation prosodique apporte à ces écrits un surcroît de signification en même temps qu'il produit un mode spécifique de représentation de l'oral appelé effet prosodique (II 3). L'angle sémantique est esquissé finalement : il conduit à dégager deux modalités de représentation supplémentaire. Pour la première, l'oral se situe sur le plan sémantico-référentiel de l'expression écrite (écrire à propos d'oral) ; pour la seconde, l'oral est un extérieur discursif modalisant le dire écrit : l'écrit est reconnu comme énoncé à la manière de l'oral (effet de style oral). - This PhD thesis attempts to review the modalities of orality in written representation. Literary writings act as the material for theorization. First of all, the thesis statement - how does writing represent oral - is situated and then, reformulated within the frame of linguistique de la parole (the linguistic field of speech) (I). The connections between orality and writing are then studied under three angles. The biotechnological angle compares the materiality and the affordance of graphic signs and acoustic signals (II 1). A semiotic examination acknowledges, in French, a phonographical system whose function is to represent the expression of French oral signs. Thus, the relationships between the systems of implicated signs, the diversity of possible actualisations of the phonographic system (voice effects), as well as various analogical semiotics are analysed (II 2). Furthermore, the role of prosody is studied within reading. The stand taken is the following : even though it is optional during a reading activity, prosody is especially sought-after by linguistically characterised writings. The prosodie interpretation brings to these writings a surge of signification while producing a specific mode of oral representation called the prosodie effects (II 3). The semantic angle is finally drawn : it leads to two additional modalities of representation. For the first part, speech is located on the semantic and referential plan of the written expression (writing about speech); as for the second part, spoken language is a discursive exteriority : writing is recognised as an oral-like utterance {oral-like effect).

Actividad extractiva de embarcaciones palangreras de bandera japonesa en aguas peruanas, 1992-1993

Se analiza información biológico-pesquera de atunes y especies afines, proveniente de la actividad extractiva de 6 atuneras palangreras de bandera japonesa que con licencias de pesca operaron en aguas jurisdiccionales del Perú, entre noviembre 1992 y octubre 1993. Las faenas de pesca se efectuaron de 0° a 14°S y desde las 30 hasta las 380 mn de la costa. Las especies capturadas fueron: atún ojo grande o patudo (Thunnus obesus), atún aleta amarilla (T. albacares) y atún aleta larga (T. alalunga). La captura total de los 6 buques palangreros fue 2.052 t, el 64% fue atún, 27% tiburones, 3% pez espada y 6% otras especies como el dorado, mantas, rayas, etc. T. obesus presentó rango de tallas entre 50 y 260 cm; T. albacares entre 50 y 170 cm y T. alalunga entre 84 y 121 cm. El índice de abundancia relativa de T. obesus se estimó en 21,2 k por cada 100 anzuelos, mientras que para T. albacares fue 18,4 k por cada 100 anzuelos, con los mayores valores en otoño e invierno.

Operaciones de pesca con chinchorro manual en Huacho, 2003

En las playas de Atahuanca, Lobiños y Playa Chica de Huacho, del 24 de febrero al 2 de marzo 2003, se desarrolló la pesca con chinchorro manual, la captura total fue 312,77 kg, correspondiendo a lisa el mayor porcentaje (39,55%). La CPUE varió entre 500 kg.h-1 y 8,77 kg.h-1. El rango de tallas varió para lisa entre 22 y 39 cm, mismis entre 11 y 31 cm; la correlación entre longitud y peso fue altamente significativa para lisa con r=0,961 y mismis r=0,997. Las correlaciones de los parámetros de longitud y el perímetro a la marca de la red registraron valores significativos con un r = 0,961 para la lisa y r = 0,973 para el mismis. Las hembras de lisa estuvieron en estadio III (26,32%) y II (21,05%) y los machos en estadio II y IV (15,79%). Las hembras de mismis estuvieron en estadio III (7,41%) y los machos en estadios IV (44,44%) y V (18,52%). Las operaciones de pesca experimental se efectuaron a 6 m de profundidad. La presencia de los recursos costeros est uvo asociada a un rango de 17,1 a 17,4 °C.

Madurez gonadal en el "Erizo Rojo" Loxechinus Albus (Molina, 1782) (Echinoidea, Echinidae)

El ciclo reproductivo de Loxechinus albus "erizo rojo" (Molina,1782), fue estudiado durante los meses de setiembre y octubre de 1996 en la zona de Atico; y desde febrero de 1997 hasta febrero de 1998 en la zona de Pisco, para la cual se midieron un total de 2266 individuos para determinar las variaciones de la estructura de tallas de este recurso. Así mismo se utilizaron un total de 724 individuos para el muestreo biológico de los cuales 312 eran hembras y 306 fueron machos , siendo de estos 106 individuos indiferenciados; colectados al azar provenientes de los desembarques de la pesca artesanal de ambas zonas . Se propone una escala de madurez gonadal consistente en 5 estadios para cada sexo , la cual se interpretó sobre la base del análisis histólogico de las gónadas,las cuales fueron relacionadas con la temperatura superficial del mar; determinándose así la estación reproductiva con los distintos periodos de evacuación de gametos.

Análise econômica do uso de leguminosas estivais intercalares à cultura do milho, na ausência e na presença de adubação nitrogenada, no oeste de Santa Catarina

O uso de leguminosas constitui boa alternativa para suprir N e aumentar o rendimento das culturas comerciais. A aceitação desta prática por agricultores e extensionistas, entretanto, depende da demonstração de sua vantagem econômica em relação ao sistema tradicional. Neste estudo, avaliou-se o efeito do cultivo intercalar de quatro leguminosas estivais de cobertura do solo [feijão de porco (Canavalia ensiformis L.), guandu (Cajanus cajan L.) cv. roxo anão, mucuna cinza (Stizolobium niveum Kuntze) e soja preta (Glycine sp)] sobre a receita líquida da cultura do milho, em três doses de N (0, 60 e 120 kg ha-1), comparativamente ao sistema tradicional de milho exclusivamente (testemunha). Dois experimentos foram realizados, durante quatro e cinco anos, respectivamente, em sistemas de preparo convencional (PC) e preparo reduzido (PR), num Latossolo Vermelho distroférrico, em Chapecó (SC), sendo os resultados apresentados na média das safras. A cultura do milho, sem leguminosa e sem adubação nitrogenada, apresentou uma receita líquida de 45 R$ ha-1 no PC e de 72 R$ ha-1 no PR. O cultivo intercalar das leguminosas promoveu incrementos na receita líquida da cultura do milho que variaram de 64 a 312 R$ ha-1 (142 a 693%), no PC, e de 57 a 147 R$ ha-1 (79 a 204%), no PR, na ausência de adubação nitrogenada. Mesmo com aplicação de N, as leguminosas promoveram aumento na receita líquida da cultura do milho, porém de menor magnitude. O cultivo intercalar de leguminosas estivais de cobertura do solo demonstrou-se uma alternativa viável para aumentar a receita líquida da cultura do milho. Os benefícios econômicos obtidos com esta prática provavelmente compensam o aumento em mão-de-obra.
