Authors: Silva Lidia Nogueira , Santos Mírian Silva , Dutra Vivian Siqueira , Araujo Elton Lucio , Costa Marco Antonio , Silva Janisete Gomes
Published: January 2012

The objective of this study was to evaluate the diversity of fruit fly (Diptera: Tephritidae) species that use myrtaceous fruit, particularly guava, as hosts in several localities in the state of Bahia and to determine the infestation rates, pupal viability rates, and fruit fly-parasitoid associations. Sampling of myrtaceous fruit was carried out in 24 municipalities in different regions in the state of Bahia. Four fruit fly species, Anastrepha fraterculus, Anastrepha zenildae, Anastrepha sororcula, and Ceratitis capitata were obtained from the collected fruit. Three parasitoid species (Hymenoptera: Braconidae) emerged from Anastrepha larvae/pupae, Doryctobracon areolatus, Utetes anastrephae, and Asobara anastrephae. Doryctobracon areolatus emerged from A. fraterculus, A. sororcula and A. zenildae; Utetes anastrephae emerged from A. fraterculus and A. zenildae; and Asobara anastrephae emerged from A. fraterculus. Fruit fly and myrtaceous fruit associations are reported for the first time in several municipalities in the state of Bahia. A. zenildae was found infesting Syzygium malaccense for the first time in Brazil.
Caracterização biométrica, física e química de frutos da palmeira bocaiuva Acrocomia aculeata (Jacq) Lodd
Authors: Sanjinez-Argandoña Eliana Janet , Chuba Carlos Alberto Machado
Published: January 2012

Frutos de palmeira bocaiuva (Acrocomia aculeata (Jacq.) Lodd.), coletados em Dourados (MS) e Presidente Epitácio (SP), foram analisados quanto ao aspecto biométrico, a composição química e as características físicas, visando a avaliar seu potencial alimentício. Os frutos de bocaiuva das regiões de procedência não apresentaram diferenças significativas entre si nas características biométricas. O rendimento médio da polpa foi de 42% em relação ao fruto inteiro, sendo superior ao encontrado na literatura para outros frutos de palmeiras. As determinações físicas e químicas da polpa dos frutos das regiões de Mato Grosso do Sul e São Paulo caracterizam a polpa como sendo pouco ácida (pH 5,70 a 6,29). As amostras de Dourados - MS, foram consideradas mais doces (14,53% de açúcares redutores totais) e com maior teor de vitamina C (34,57 mg.100 g-1) em relação às amostras de Presidente Epitácio-SP (11,46 mg.100 g-1). Porém, a intensidade da cor amarelo-laranja foi maior na polpa dos frutos de Presidente Epitácio (SP), sugerindo maior conteúdo de carotenoides.
Obesidade infantil na percepção dos pais
Authors: Tenorio Aline e Silva , Cobayashi Fernanda
Published: January 2012

OBJETIVO: Revisar as pesquisas atuais sobre a capacidade dos pais para perceber o peso corporal dos filhos, as crenças relacionadas ao peso, os fatores que influenciam essa percepção, assim como as possíveis ações capazes de ampliar a consciência dos pais sobre o excesso de peso de seus filhos e suas consequências. FONTES DE DADOS: As bases de dados utilizadas na pesquisa foram: Medline - Pubmed, SciELO e Scopus. Foram incluídos os artigos publicados nos últimos dez anos (2000 a 2010) relacionados ao tema e que abordavam a faixa pediátrica e os fatores condicionantes da percepção dos pais a respeito do peso dos filhos. SÍNTESE DOS DADOS: A percepção dos pais quanto ao peso dos filhos foi sempre baixa, apesar da diversidade das amostras estudadas, regiões diferentes, nível socioeconômico e escolaridade variada. Muitos pais de filhos com excesso de peso não reconhecem ou não consideram que este seja um problema de saúde. Com relação aos fatores que influenciam a percepção, destacam-se a idade das crianças (quanto menor, menos se percebe o excesso de peso); o sexo (o peso das meninas é percebido corretamente); a baixa escolaridade e o não entendimento das curvas de crescimento. CONCLUSÕES: A falta de percepção e consciência dos pais quanto ao estado nutricional dos filhos é um dos fatores que dificulta o sucesso da prevenção, tratamento e consequente diminuição da prevalência da obesidade.

As mulheres no mundo equestre: forjando corporalidades e subjetividades 'diferentes'
Authors: Adelman Miriam
Published: January 2012

Desde o final do século XIX, as práticas esportivas se tornaram um terreno de lutas simbólicas e práticas intensas sobre definições de feminilidade, sobre "o que é uma mulher" e quais as atividades que um corpo marcado como feminino pode ou deve realizar. Durante mais de uma década, venho realizando pesquisa sobre a prática esportiva de mulheres no Brasil, com um olhar para o mundo equestre. Apresentarei um resumo dessas pesquisas que vêm focalizando diferentes grupos de amazonas: inicialmente, um grupo de amazonas de origem social de elite que se dedicam ao salto (hipismo clássico), num segundo momento, jovens de origem popular que lutam para inserir-se no meio muito masculino do turfe e, finalmente, uma nova fase de pesquisa que se abre para o mundo tradicional do "rodeio campeiro" e suas pioneiras. Através de depoimentos de mulheres e de trabalho de cunho etnográfico e interacionista, procuro entender como as práticas dessas mulheres fazem parte de processos de construção identitária particulares, como lidam com meios que continuam sendo predominantemente masculinos e desenvolvem, nesses contextos, estratégias de autoafirmação, individuais ou coletivas. Apesar das pressões normativas e dos obstáculos culturais e/ou materiais que encontram no caminho, identifico nas suas práticas e modos de ser elementos de desafio às formas mais convencionais de viver o corpo e a subjetividade.

Authors: Sanches Luiz Miguel Picelli , Jensen Rodrigo , Monteiro Maria Inês , Lopes Maria Helena Baena de Moraes
Published: January 2012

This descriptive study aimed to verify the inclusion of subjects about informatics in undergraduate nursing programs at Brazilian (state and federal) public education institutions. The programs were located through the e-MEC system. The Internet was used to search for the curricula of the campuses offering the nursing program and identify subjects related to informatics. Eighty-one higher education institutions and 123 campuses were located. Only 100 campuses provided the curriculum on the Internet, 35 of which offered the subject. The highest proportion occurred in the Northeast (46.1%) and the lowest in the North (8.6%). The subject is mostly offered as an elective discipline (57%) in the first and second year (80%), with an average workload of 47 classroom hours. The low supply of this undergraduate subject goes against job market trends and the National Curriculum Guidelines for Undergraduate Nursing Programs.

Published: January 2012

The nurse has a key role in involving parents in the care of newborns in the neonatal intensive care unit. The aim of this study was to comprehend how the nurses experience the care provided to newborns in the presence of the parents. This is a qualitative study using social phenomenology, with the participation of seven nurses, interviewed between January and February 2009. The nurses perceived the needs of parents; had positive expectations regarding the care provided and acknowledge themselves to be the link between them, helping them to live with the hospitalized child. However, in emergencies, the nurses had difficulties in caring for the neonate in the presence of the parents. The nurses positively evaluated the presence of parents in the neonatal intensive care unit, involving them permanently in the care of the newborn. The study evokes the emergence of a care context (nurse/neonate/parents) that precedes the proximity between the subjects and the demands presented by them.

Authors: Fernandes Ana Fátima Carvalho , Santos Míria Conceição Lavinas , Silva Tiago Barreto de Castro e , Galvão Cristina Maria
Published: January 2012

This integrative review analyzed evidence available in the literature concerning the prognosis of breast cancer during pregnancy. The following databases were used for selecting studies: PubMed, CINAHL and LILACS. A total of 240 primary studies were identified; 13 papers were included in the integrative review’s sample after reading the titles and abstracts and according to the established inclusion and exclusion criteria. There is evidence indicating that pregnancy does not worsen the evolution of breast cancer and a poor prognosis is related to late stage tumors. Among the gaps identified in the studied theme, the need for further studies addressing nursing care provided to pregnant women with breast cancer is highlighted in order to promote improved care in the context of health care.
As relações entre China e América Latina: impactos de curta ou longa duração?
Authors: Ferchen Matt
Published: January 2012

O artigo foca as relações de negócios e investimentos entre China e América Latina na década de 2000. Há três interpretações principais, distintas e relacionadas, sobre esse conjunto de relações: para a primeira, a América Latina, uma região com recursos naturais abundantes, exporta produtos primários para uma China em expansão, mas carente de tais recursos. Sustentam essa interpretação aqueles, incluindo muitos representantes proeminentes do governo, que afirmam as relações econômicas entre China e América Latina serem fundamentalmente complementares, tendo um efeito positivo para ambas as partes. Em contrapartida, outros observadores têm destacado que o que é visto como complementaridade é na verdade apenas uma forma renovada de dependência latino-americana. Esses autores alegam que, apesar da rápida expansão dos negócios e investimentos trazer benefícios no curtoprazo para ambos os lados, essa natureza de relações baseada em commodities reforça os padrões disfuncionais de desenvolvimento da América Latina que muitos países da região há muito tempo renunciaram e têm tentando deixar para trás há mais de meio século. Tomando essa discussão como referência, apresenta-se, em primeiro lugar, uma visão geral das relações de comércio e investimentos entre China e América Latina, destacando o papel importante da demanda chinesa por commodities latino-americanas. Em segundo, descreve-se as diferentes interpretações sobre o que conduz essa relação comercial e quais são as suas conseqüências. Em terceiro, apresenta-se o argumento, por nós defendido, sobre como nós deveríamos entender o que tem conduzido as relações econômicas entre China e América Latina e o que está em jogo. Conclui-se explorando as implicações das nossas descobertas para a idéia de que a China oferece um modelo único de economia política doméstica e internacional.
As características dos alunos são determinantes para o adoecimento de professores: um estudo comparativo sobre a incidência de Burnout em professores do ensino regular e especial
Authors: Silva Nilson Rogério da , Almeida Maria Amélia
Published: January 2012

O exercício da docência é permeado por condições de trabalho adversas, baixos salários, insuficiência de recursos materiais e didáticos, salas numerosas, tensão no relacionamento com os alunos, carga horária de trabalho excessiva, inexpressiva participação no planejamento da instituição e nas políticas institucionais e falta de segurança no ambiente escolar. O presente estudo teve por objetivo comparar a presença de indicadores de burnout em três grupos de professores que atuam no primeiro ciclo do Ensino Fundamental: a) 20 no ensino regular, em turmas sem a inserção de alunos com necessidades educacionais especiais - RSI; b) 20 no ensino regular, em turmas com a inserção de alunos com necessidades educacionais especiais - RCI; c) 20 em salas de recursos - SR. Para a coleta, foi utilizado o Maslach Burnout Inventory -MBI. Na análise de dados, empregou-se o SPSS, versão 13.0, e o Teste de Kruskal-Wallis para comparação dos grupos. Os resultados, que foram organizados em forma de Figuras e Tabelas, revelam que, de maneira geral, os grupos apresentaram relativa similaridade. Entretanto, algumas diferenças foram encontradas. O grupo de professores SR obteve os melhores resultados na avaliação das três escalas do burnout, quando comparado com RSI e RCI, ou seja, com predominância de respostas nos níveis mais baixos de exaustão emocional, altos na diminuição da realização pessoal e baixos para despersonalização. Espera-se que os dados expostos contribuam para a compreensão do burnout em professores do ensino regular com e sem inclusão de alunos com necessidades educacionais especiais, e/ou suscitem novos encaminhamentos de pesquisas.
Giving Birth With Epidural Analgesia: The Experience of First-Time Mothers
Authors: Hidaka Ryoko , Callister Lynn Clark
Published: January 2012

The purpose of our qualitative descriptive study was to describe the birth experiences of women using epidural analgesia for pain management. We interviewed nine primiparas who experienced vaginal births. Five themes emerged: (a) coping with pain, (b) finding epidural administration uneventful, (c) feeling relief having an epidural, (d) experiencing joy, and (e) having unsettled feelings of ambivalence. Although epidural analgesia was found to be effective for pain relief and may contribute to some women’s satisfaction with the birth experience, it does not guarantee a quality birth experience. In order to support and promote childbearing women’s decision making, we recommend improved education on the variety of available pain management options, including their risks and benefits. Fostering a sense of caring, connection, and control in women is a key factor to ensure positive birth experiences, regardless of pain management method.
Risk, Safety, and Choice in Childbirth
Authors: Lothian Judith A.
Published: January 2012

In this column, the author explores current understandings of risk and safety in pregnancy and childbirth. An emphasis on risk management places the provider and hospital in control of women’s decisions related to pregnancy and birth and may make pregnancy and birth less safe for mothers and babies. Accepting that no life is risk free, women can let go of fear and make choices that take into account real, not imagined, or exaggerated risk and, in doing so, increase safety for themselves and their babies. The focus of maternity care becomes enhancing safety through evidence-based practice rather than managing risk.
Midwives, Obstetrics, Fear, and Trust: A Four-Part Invention
Authors: De Vries Raymond G.
Published: January 2012

When done well, maternity care brings together four “voices”: the voice of midwifery, which sees birth as a healthy physiological process; the voice of obstetrics, which can manage pathology; the voice of fear (or respect), which encourages vigilance; and the voice of trust, which allows a woman to have confidence in herself and her caregivers. Our goal is to keep these voices singing in harmony.

Sensitivity of skeletal muscle to pro-apoptotic factors
Authors: Otrocka-Domagała I.
Published: January 2012

Sensitivity of skeletal muscle to pro-apoptotic factors

In mononuclear cells, apoptosis leads to DNA fragmentation and cell destruction, regardless of the activated pathway. As regards multinuclear cells, e.g. skeletal muscle fibers, apoptosis rarely induces the death of the entire cell, and it generally affects single nuclei. This process, referred to as nuclear apoptosis, has a negative effect on the expression of genes in the myonuclear domain. Apoptosis may be initiated in muscle cells by external stimuli which activate cell membrane death receptors as well as by internal stimuli which stimulate the mitochondrial release of pro-apoptotic proteins. Reactive oxygen species also play an important role in the initiation of apoptosis. In muscle cells, ROS are produced in response to extracellular reactions or by cell mitochondria. It is, therefore, believed that mitochondria play a central role in apoptosis within skeletal muscle. Skeletal muscles have a well-developed system that protects them against oxidative damage. Myogenic stem cells are an integral part of multinucleated myofibers, and they are critically important for the maintenance of normal muscle mass, muscle growth, regeneration and hypertrophy. The latest research results indicate that myogenic cells are more sensitive to oxidative stress and pro-apoptotic factors than well-differentiated cells, such as myotubes. The complex structure and activity of skeletal muscle prompted research into the role of apoptosis and its intensity under various physiological and pathological conditions. This review summarizes the results of research investigating control mechanisms and the apoptosis process in skeletal muscle fibers, and indicates unresearched areas where further work is required.

Influence of the Hydrogen Reduction Time and Temperature on the Morphology Evolution and Hematite/Magnetite Conversion of Spindle-Type Hematite Nanoparticles
Authors: Chappuis Thierry , Bobowska Izabela , Hengsberger Stefan , Vanoli Ennio , Dietsch Hervé
Published: January 2012

We report on the transformation via hydrogen reduction of spindle-type hematite nanoparticles into hematite/magnetite hybrid iron oxide particles. The transformation process consists of the reduction of nanoparticles powder in an autoclave using hydrogen gas at a fixed pressure
of 11 bars. Both temperature and time of reduction are varied between 300 °C to 360 °C and 0 to 45 h. X-Ray powder diffraction data on the obtained powder and corresponding Rietveld refinement allow the amount of reduced hematite to be determined as a function of these two parameters.
Kinetics parameters are measured and an estimation of the activation energy is obtained through linearization of the Arrhenius equation. While reduction is dramatically accelerated at higher temperature, the morphology of the nanoparticles only remain qualitatively unchanged at 300 °C
as seen from transmission electron microscopy images. The mechanisms underlying morphology changes are still under study and seem to be closely related to reactor pressure.

In 1911 Aleksander Stenbock-Fermor, a Russian aristocrat, offered the Muséum National d'Histoire Naturelle, Paris, a well-preserved mammoth from Lyakhowskiy Island, New Siberian Isles. This paper presents a hitherto unpublished memorandum that Stenbock-Fermor addressed to Edmond Perrier, the Museum's director, which related the circumstances surrounding the discovery, removal and transportation of the mammoth from Siberia to St Petersburg and thence to Paris. The paper also presents some biographical information on Konstany Wołłossowicz, who explored Siberia and who organized the expedition to Lyakhowskiy Island in order to bring the mammoth to Europe.
Recent Advances in Polymeric Materials Used as Electron Mediators and Immobilizing Matrices in Developing Enzyme Electrodes
Authors: Moyo Mambo , Okonkwo Jonathan O. , Agyei Nana M.
Published: January 2012

Different classes of polymeric materials such as nanomaterials, sol-gel materials, conducting polymers, functional polymers and biomaterials have been used in the design of sensors and biosensors. Various methods have been used, for example from direct adsorption, covalent bonding, crossing-linking with glutaraldehyde on composites to mixing the enzymes or use of functionalized beads for the design of sensors and biosensors using these polymeric materials in recent years. It is widely acknowledged that analytical sensing at electrodes modified with polymeric materials results in low detection limits, high sensitivities, lower applied potential, good stability, efficient electron transfer and easier immobilization of enzymes on electrodes such that sensing and biosensing of environmental pollutants is made easier. However, there are a number of challenges to be addressed in order to fulfill the applications of polymeric based polymers such as cost and shortening the long laboratory synthetic pathways involved in sensor preparation. Furthermore, the toxicological effects on flora and fauna of some of these polymeric materials have not been well studied. Given these disadvantages, efforts are now geared towards introducing low cost biomaterials that can serve as alternatives for the development of novel electrochemical sensors and biosensors. This review highlights recent contributions in the development of the electrochemical sensors and biosensors based on different polymeric material. The synergistic action of some of these polymeric materials and nanocomposites imposed when combined on electrode during sensing is discussed.

Objective.

To describe clinical fracture rates, back pain, and health-related quality of life (HRQOL) in postmenopausal women with osteoporosis who are receiving glucocorticoids (GC), during a 36-month study of teriparatide treatment for up to 18 months, with an additional 18-month followup period when patients were receiving other osteoporosis medications.

Methods.

A prospective, multinational, observational study. Data for clinical fractures, back pain (by visual analog scale; VAS) and HRQOL (by EQ-5D) were collected over 36 months. Fracture data were summarized in 6-month segments and analyzed using logistic regression with repeated measures. Changes from baseline in back pain VAS and EQ-VAS were analyzed.

Results.

Of 1581 enrolled women with followup data, 294 (18.6%) had antecedents of GC use. Of these, 49 (16.7%) patients sustained a total of 69 fractures during the 36-month study period. Adjusted odds of fracture were significantly decreased during the last year of followup compared with the first 6 months of teriparatide treatment: an 81% decrease in the 24 to < 30-month period (p < 0.05), and an 89% decrease in the 30 to < 36-month period (p < 0.05). There were significant reductions in back pain and improvements in HRQOL in both groups of GC users and nonusers.

Conclusion.

Postmenopausal women with severe osteoporosis receiving GC, who were treated with teriparatide for up to 18 months, showed a reduced incidence of clinical fractures during the third year while receiving sequential osteoporosis treatments compared with the first 6 months, together with reduced back pain and improved HRQOL. Our results should be interpreted in the context of an uncontrolled observational study in a routine clinical setting.

Sri Lanka’s Aruwakkalu fossil deposit dates to the Burdigalian Age

Published: January 2012

Aruwakkalu fossil bed is a part of Sri Lanka’s Jaffna limestone, which underlies the whole of Jaffna Peninsula and extends southwards mostly along the west coast. Previous authors have suggested that Aruwakkalu contains a rich assemblage of vertebrate and invertebrate fossils. We sought to confirm the Burdigalian age of this northwestern Miocene deposit at Aruwakkalu on the basis of the foraminifer Pseudotaberina malabarica, an index fossil of the Burdigalian stage. General and timeline collections were made at seven selected sites and the fossils collected were identified. The study sites contained six sedimentary layers of which, third and sixth from top were fossiliferous. The sixth (deepest) layer was dominated by gastropod fossils while the third was dominated by fossils of giant oysters. Fossils of P. malabarica were recovered both from timeline and general collections. In the timeline collection, samples of this index fossil were recovered only from the gastropod layer, suggesting that P. malabarica existed during the time the gastropod layer was being laid down, thus confirming a Burdigalian age for the latter, and helping to date a substantial portion of the Sri Lankan fossil fauna with confidence.   Key words: Pseudotaberina malabarica; foraminifera; index fossil; Miocene; gastropod layer; oyster layer DOI: http://dx.doi.org/10.4038/cjsbs.v40i2.3933 CJSBS 2011; 40(2): 163-174
Snowpack concentrations and estimated fluxes of volatile organic compounds in a boreal forest
Authors: Aaltonen H. , Pumpanen J. , Hakola H. , Vesala T. , Rasmus S. , Bäck J.
Published: January 2012

Abstract. Soil forms an important source for volatile organic compounds (VOCs), but in boreal forests these fluxes and their seasonal variations have not been characterized in detail, especially wintertime fluxes, which are almost completely unstudied. In this study, we measured the VOC concentrations inside a snowpack in a boreal Scots pine (Pinus sylvestris L.) forest in southern Finland, using adsorbent tubes and air samplers installed permanently in the snow profile. Based on the VOC concentrations at three heights inside the snowpack, we estimated the fluxes of these gases. We measured 20 VOCs from the snowpack, monoterpenes being the most abundant group with concentrations varying from 0.11 to 16 μg m−3. Sesquiterpenes and oxygen-containing monoterpenes were also detected. Inside the pristine snowpack, the concentrations of terpenoids decreased from the soil surface towards the snow surface, suggesting soil as being the source for terpenoids. Forest damages resulting from heavy snow loading during the measurement period increased the terpenoid concentrations dramatically, especially in the upper part of the snowpack. The results show that soil processes are also active and efficient VOC sources during winter and that natural or human disturbance can increase forest floor VOC concentrations substantially. Our results stress the importance of soil as a source of VOCs during the season when other biological sources, basically plants, have lower activity.
Estimation of the global inventory of methane hydrates in marine sediments using transfer functions
Authors: Piñero E. , Marquardt M. , Hensen C. , Haeckel M. , Wallmann K.
Published: January 2012

Abstract. The accumulation of gas hydrates in marine sediments is essentially controlled by the accumulation of particulate organic carbon (POCar) which is microbially converted into methane, the thickness of the gas hydrate stability zone (GHSZ) where methane can be trapped, and the delivery of methane from deep-seated sediments by ascending pore fluids and gas into the GHSZ. Recently, Marquardt et al. (2010) developed a transfer function to predict the gas hydrate inventory in diffusion-controlled geological systems based on POCar and GHSZ. We present a new parameterization of this function and apply it to global datasets of bathymetry, heat flow, seafloor temperature and organic carbon accumulation estimating a global mass of only 91 Gt of carbon (GtC) stored in marine methane hydrates. Seepage of methane-rich fluids is known to have a pronounced effect on gas hydrate accumulation. Therefore, we carried out a set of systematic model runs with the transport-reaction code in order to derive an extended transfer function explicitly considering upward fluid advection. Using averaged fluid velocities for active and passive margins, which were derived from mass balance considerations, this extended transfer function predicts the formation of gas hydrates along the continental margins worldwide. Different scenarios were investigated resulting in a global mass of sub-seafloor gas hydrates of 400–1100 GtC. Overall, our systematic approach allows to clearly and quantitatively distinguish between the effect of biogenic methane generation from POC and fluid advection on the accumulation of gas hydrate and hence, provides a simple prognostic tool for the estimation of large-scale and global gas hydrate inventories in marine sediments.

Greenhouse Gas Emissions and Sustainability in Lagos Metropolis, Nigeria
Authors: Aderogba Kofo A
Published: January 2012

Abstract The enhancement of the greenhouse effect in driving increases in temperature and many other changes associated with climate have become great concern to research. The objective of this paper is to estimate the amount of greenhouse gases in the atmosphere in Lagos Metropolis. Literatures on road and air travels were read; and also journal articles on pollution and greenhouse gases, global warming and climate change. Newspaper cuttings, magazines, and electronic media sources of data and information were used. Trends in the growth and development of railway locomotives, marine activities, vehicular movements and air travels in the metropolis were studied and correlated with the estimated greenhouse gases emitted. There is positive correlation. Vehicular movements and air travels have increased by over 50% in the last twenty years. Greenhouse gases are increasing by the day. There must be deliberate checks on gas emission from automobiles, plants and machineries and in the aviation industry.  The world is not at rest to arrest the effects of climate change and global warming.  Nigeria and Nigerians and particularly Lagosian, the government and research institutions should be parts of the efforts.   Key words: Greenhouse Gas, Emissions, Predicaments, Economic Value, Lagos Metropolis.
IFAD Projects: Results and Impact on Poverty Reduction in Rural China
Authors: Shuai Chuanmin , Li Zhou , Sun Ruomei
Published: January 2012

This paper analyses the economic, social and ecological benefits of projects of the International Fund for Agriculture Development (IFAD) in China during the past two-and-a-half decades. An investigation was carried out through field visits to Jilin, Anhui, Shaanxi and Qinghai provinces and a comprehensive assessment was made of 12 IFAD projects in 13 provinces. The authors offer a systematic examination of the projects' impact on China's rural poverty reduction in five respects: food security, women and vulnerable groups, government policies on poverty reduction, state policies on rural finance, and institutional and capacity building of the Chinese government and the community. It is concluded that IFAD projects have achieved outstanding results and far-reaching impacts, and have played an important role in rural poverty reduction. Finally, with regard to policy recommendations, the authors propose that the Chinese government should: (a) continue to cooperate with IFAD for rural poverty reduction; (b) play IFAD's demonstrative role in other poor areas of China; and (c) facilitate the institutional reform of China's rural financial system.
Dynamic Analysis of Honeycomb Sandwich Beam with Multiple Debonds
Authors: Saraswathy B. , Ramesh Kumar R. , Mangal Lalu
Published: January 2012

Analytical formulation for the evaluation of frequency of CFRP sandwich beam with debond, following the split beam theory, generally underestimates the stiffness, as the contact between the honeycomb core and the skin during vibration is not considered in the region of debond. The validation of the present analytical solution for multiple-debond size is established through 3D finite element analysis, wherein geometry of honeycomb core is modeled as it is, with contact element introduced in the debond region. Nonlinear transient analysis is followed by fast Fourier transform analysis to obtain the frequency response functions. Frequencies are obtained for two types of model having single debond and double debond, at different spacing between them, with debond size up to 40% of beam length. The analytical solution is validated for a debond length of 15% of the beam length, and with the presence of two debonds of same size, the reduction in frequency with respect to that of an intact beam is the same as that of a single-debond case, when the debonds are well separated by three times the size of debond. It is also observed that a single long debond can result in significant reduction in the frequencies of the beam than multiple debond of comparable length.
Relationship between Latitude and Melanoma in Italy

Published: January 2012

Objective. Evaluate the ecological relationship between skin melanoma epidemiology and latitude in Italy. Methods. We used data from the Italian network of cancer registries (Airtum). In a Poisson model, we evaluated the effect on incidence, mortality, and survival of latitude, adjusting for some demographic, social, phenotypic, and behavioural variables. Results. Incidence increased in Italy by 17% for each degree of increase in latitude. The effect of latitude was statistically significantly present also adjusting for other variables (incidence rate ratio = 1.08). The effect of latitude on increasing mortality (mortality rate ratio = 1.27) and improving survival (relative excess risk of death = 0.93) was no longer present in the multivariate model. Conclusion. Melanoma incidence, mortality, and survival vary in Italy according to latitude. After adjustment for several confounders, incidence still grows with growing latitude. Presumably, latitude expresses other variables that might be related to individual susceptibility and/or local care.

La estética de los medios omnipresentes
Authors: Dovey Jonathan , Fleuriot Constance
Published: January 2012

Este trabajo surge de una colaboración para el intercambio de conocimientos entre el Pervasive Media Studio de Bristol (Reino Unido) y el Digital Cultures Research Centre (DCRC) de la University of the West of England. En él se ofrecen técnicas conceptuales, vocabularios descriptivos y herramientas de diseño pragmáticas para adentrarnos en el incipiente campo de los medios omnipresentes (pervasive media, en inglés). Los lenguajes y los vocabularios tienen su origen y se emplazan en los ámbitos de la investigación y el desarrollo, vinculando comunidades de práctica. Esta presentación hace referencia al desarrollo de un vocabulario colectivo sobre los medios omnipresentes que ha planteado una cuestión fundamental en el proyecto Knowledge Transfer Fellowship (KTF) para el intercambio de conocimientos. La KTF y el DCDR se crearon para responder a la necesidad detectada de investigar definiciones y nuevos modelos de creación de valor en las empresas de medios digitales. El eslogan de los medios omnipresentes promete «los medios adecuados, en el lugar adecuado y en el momento adecuado», en las pantallas de los teléfonos, en los auriculares, en pequeñas y grandes proyecciones y con una variedad de géneros interactivos en vías de expansión. Para CBS Advertising se trata simplemente de «medios de publicidad exterior», una ampliación de las vallas publicitarias que ofrece el potencial necesario para intensificar el dominio que ejerce la publicidad en nuestro compromiso con la competencia terminal de la economía de la atención digital. ¿Qué otros modelos de redes de valor podrían respaldar los medios omnipresentes? El presente artículo se basa en el trabajo realizado en el marco de la KTF, una asociación para el intercambio de conocimientos con sede en el Pervasive Media Studio de Bristol (Reino Unido), donde hemos estado trabajando con iniciativas digitales para analizar el modo en que interactúan los valores, las economías y los ecosistemas de medios. Mediante una serie de ejemplos recientes en la práctica de los medios omnipresentes, el artículo ofrecerá un análisis del valor generado por los ecosistemas de medios que habitan y co-crean.
Reconstruyendo las ruinas del futuro: dogmas e interrogaciones de la imagen digital
Authors: Zunzunegui Díez Santos
Published: January 2012

La irrupción de lo digital plantea nuevos retos y proporciona nuevas posibilidades creativas al cinematógrafo. Esto sucede en el momento en que se están modificando, de forma sustancial, las formas de recepción de los filmes y se están borrando las fronteras que hasta ahora venían definiendo las formas de almacenamiento, difusión y gestión de las nuevas imágenes. Imágenes que ya no pueden ser descritas bajo la obsoleta denominación de audiovisual. Esta revolución permite constatar, de una vez por todas, que la fuerza de la imagen está menos en su cualidad de revelar un visible preexistente que en su capacidad para crear su propio referente mediante una operación de designación del mismo: la imagen como aquello que apunta (señalándolo, creándolo) hacia algo exterior a ella. En medio de este complejo territorio de mutaciones algunos cineastas sacan partido de esta neo-imagen para explorar nuevos terrenos creativos.

Much effort has been focused on improving assisted reproductive technology procedures in humans and nonhuman primates (NHPs). However, the pregnancy rate after embryo transfer (ET) has not been satisfactory, indicating that some barriers still need to be overcome in this important procedure. One of the key factors is embryo–uterine synchronicity, which is little known in NHPs. The objective of this study was to investigate the available ET time window in rhesus monkey (Macaca mulatta). Eighty‐two adult female rhesus monkeys were superovulated with recombinant human FSH. Ovarian phases were identified according to estrogen (E2) and progesterone (P4) levels as well as ovarian examination by ultrasonography and laparoscopy. A total of 259 embryos were transferred by the laparoscopic approach into the oviducts of 63 adult female monkeys. Ovarian phases were divided into late follicular and early luteal phases. Similar pregnancy rates (30–36.4%) were obtained from recipients receiving ET either in their late follicular or early luteal phases, regardless of embryo developmental stages. This study indicates that the available time window for ET in rhesus monkeys is from the late follicular to early luteal phases.
