Major demographic changes in Bangladesh and their socio-economic correlates: Analysis of trends

Catalogues the demographic changes in Bangladesh during the period 1975-2000 and examines how they relate to key socio-economic attributes. Trends are examined in population growth, growth of the working age population, women’s workforce participation, age-dependency ratio, female-male ratio, longevity, fertility, mortality and mean age at first marriage. Bangladesh has made significant breakthroughs in all these areas, a feat not matched by most other South Asian countries, but comparable with the South-East Asia region as whole. The study isolates factors contributing to the changes in each attribute. It assesses the correlation between Bangladesh’s demographic changes and selected socio-economic indicators namely, its per capita GDP, female labour force participation, per capita public health expenditure and educational achievements by both men and women. All five socio-economic variables display statistically significant correlation, in varying degrees, with measures of the demographic changes. Per capita GDP is probably the most significant determinant of demographic changes in Bangladesh. The study observes that men’s education reinforces women’s education and with increased workforce participation contributed to reduced fertility. The study suggests that the role of family planning programs in curbing population growth in Bangladesh maybe overestimated.

Communication and health beliefs - Mass and interpersonal influences on perceptions of risk to self and others

This study investigated the impact of media coverage of a health issue (skin cancer) on judgements of risk to self and others and the role of related communication processes. Consistent with predictions derived from the impersonal impact hypothesis, the effects of mass communication were more evident in perceptions of risk to others rather than in perceptions of personal risk. Perceptions of personal risk were more strongly correlated with interpersonal communication. However, as suggested by media system dependency theory, the relationship between mass communication and beliefs was complex. The impact of mass communication on both personal and impersonal perceptions was bound to be moderated by self-reported dependence on mass mediated information. The effect of this two-way interaction 071 perceptions of personal risk was partially mediated through interpersonal communication. Results point to the interdependence of mass and interpersonal communication as sources of social influence and the role of media dependency in shaping media impact.

Responses of sugarcane, maize, and soybean to phosphorus and vesicular-arbuscular mycorrhizal fungi

The presence of vesicular-arbuscular mycorrhizal (VAM) fungi in long-term cane-growing fields associated with yield decline led to the supposition that VAM fungi may be responsible for the poor yields. A glasshouse trial was established to test the effectiveness of a species of VAM fungi, Glomus clarum, extracted from one of these North Queensland fields on the growth of sugarcane (Saccharum interspecific hybrid), maize (Zea mays), and soybean (Glycine max) for 6 phosphorus (P) rates (0, 2.7, 8.2, 25, 74, 222 mg/kg). For maize and soybean plants that received VAM (+ VAM), root colonisation was associated with enhanced P uptake, improved dry weight (DW) production, and higher index tissue-P concentrations than those without VAM (-VAM). By comparing DW responses of maize and soybean for different P rates, savings in fertiliser P of up to 160 and 213 kg/ha, respectively, were realised. Sugarcane plants were generally less responsive. Apart from a 30% DW increase with VAM when 2.7 mg P/kg was added, DW of +VAM plants was equivalent to, or worse than in the case of 222 mg P/kg, DW of -VAM plants. For all 3 host species, colonisation was least at the highest P application, presumably from excessive P within the plant tissue. Critical P concentrations for the 3 host species were below those reported elsewhere, and for soybean and sugarcane, the critical concentration for +VAM plants was lower than that of -VAM plants. There are 3 implications that arise from this study. First, VAM fungi present in cane-growing soils can promote the growth of maize and soybean, which are potential rotation crops, over a range of P levels. Second, the mycorrhizal strain taken from this site did not generally contribute to a yield decline in sugarcane plants. Third, application of P fertiliser is not necessary for sugarcane when acid-extractable P is

Vibration instability in rolling mills: Modeling and experimental results

Models for the occurrence of the vibrational instability during rolling known as third octave chatter are presented and discussed. An analysis of rolling mill chatter was performed for the purpose of identifying characteristics of the vibrations and to determine any dependency on the rolling schedule. In particular, a stability criterion for the critical rolling speed is used to predict the maximum rolling speed without chatter instability on schedules from a 5 stand tandem mill rolling thin steel product. The results correlate well with measurements of critical speed occurring on the mill using a vibration monitor: This research provides significant insights into the chatter phenomena and has been used to investigate control methods for suppression of the instability.

Well-formedness judgment: A comparison of offline and online performance in Broca's aphasics

However, the methodologies used to establish this aspect of the performance profile of the ACD have been predominantly offline. Offline well-formedness tasks entail extralinguistic processing (e.g. perception, attention, short-term memory, conscious reflection) in varying amounts and the influence of such processes on parsing mechanisms is yet to be fully established. In order to (a) further understand the role of extra-linguistic processing on parsing, and (b) gain a more direct insight into the online nature of parsing in Broca’s aphasia, 8 subjects underwent a series of wellformedness judgment investigations using both offline and online test batteries. The sentence types and error types used were motivated by three current theories about the nature of the ACD, namely, the Trace-Based Account (Grodzinsky, 2000), the Mapping Hypothesis (Linebarger et al., 1983) and Capacity proposals (e.g. Frazier & Friederici, 1991). The results from the present investigation speak directly to the three aforementioned theories and also demonstrate the important role that extralinguistic processing plays during offline assessment. The clinical implications of the different outcomes from the offline vs. online tasks are also discussed.

Ventilatory effects of neurophysiological facilitation and passive movement in patients with neurological injury

Thirteen intubated, high dependency patients with neurological injuries were studied in order to investigate the short term respiratory effects of neurophysiological facilitation and passive movement on tidal volume (V-T), minute ventilation (V-E), respiratory rate (V-R) and oxygen saturation (SpO(2)). The subjects were studied under four conditions: no intervention (control) and during periods of neurophysiological facilitation, passive movement and sensory stimulation. All periods were standardised to three minutes duration and all parameters were recorded before and after each intervention. Neurophysiological facilitation produced significant increases (p < 0.01) in V-E and SpO(2) (p < 0.05) when compared with control values, with an overall mean increase in V-E of 14.6%. Similarly, passive movement increased V-E (p < 0.01) by an average of 9.8% and also increased SpO(2) (p < 0.01). In contrast, sensory stimulation produced significant increases (p < 0.01) in SpO(2) with control levels, with no significant change in V-T or V-E. There was no significant difference in V-R with all treatments. This study provides preliminary evidence of improved short term ventilatory function following neurophysiological facilitation, independent of generalised sensory stimulation, which has not been previously examined in the literature, supporting its use in the management of high dependency neurological patients.

Product form approximations for highly linear loss networks with trunk reservation

Admission controls, such as trunk reservation, are often used in loss networks to optimise their performance. Since the numerical evaluation of performance measures is complex, much attention has been given to finding approximation methods. The Erlang Fixed-Point (EFP) approximation, which is based on an independent blocking assumption, has been used for networks both with and without controls. Several more elaborate approximation methods which account for dependencies in blocking behaviour have been developed for the uncontrolled setting. This paper is an exploratory investigation of extensions and synthesis of these methods to systems with controls, in particular, trunk reservation. In order to isolate the dependency factor, we restrict our attention to a highly linear network. We will compare the performance of the resulting approximations against the benchmark of the EFP approximation extended to the trunk reservation setting. By doing this, we seek to gain insight into the critical factors in constructing an effective approximation. (C) 2003 Elsevier Ltd. All rights reserved.

Predicting cave initiation and propagation

The most widely used method for predicting the onset of continuous caving is Laubscher's caving chart. A detailed examination of this method was undertaken which concluded that it had limitations which may impact on results, particularly when dealing with stronger rock masses that are outside current experience. These limitations relate to inadequate guidelines for adjustment factors to rock mass rating (RMR), concerns about the position on the chart of critical case history data, undocumented changes to the method and an inadequate number of data points to be confident of stability boundaries. A review was undertaken on the application and reliability of a numerical method of assessing cavability. The review highlighted a number of issues, which at this stage, make numerical continuum methods problematic for predicting cavability. This is in particular reference to sensitivity to input parameters that are difficult to determine accurately and mesh dependency. An extended version of the Mathews method for open stope design was developed as an alternative method of predicting the onset of continuous caving. A number of caving case histories were collected and analyzed and a caving boundary delineated statistically on the Mathews stability graph. The definition of the caving boundary was aided by the existence of a large and wide-ranging stability database from non-caving mines. A caving rate model was extrapolated from the extended Mathews stability graph but could only be partially validated due to a lack of reliable data.

eMelanoBase: An online locus-specific variant database for familial melanoma

A proportion of melanoma,prone individuals in both familial and non,familial contexts has been shown to carry inactivating mutations in either CDKN2A or, rarely, CDK4. CDKN2A is a complex locus that encodes two unrelated proteins from alternately spliced transcripts that are read in different frames. The alpha transcript (exons 1a, 2, and 3) produces the p16INK4A cyclin-dependent kinase inhibitor, while the beta transcript (exons 1beta and 2) is translated as p14ARF, a stabilizing factor of p53 levels through binding to MDM2. Mutations in exon 2 can impair both polypeptides and insertions and deletions in exons 1alpha, 1beta, and 2, which can theoretically generate p16INK4A,p14ARF fusion proteins. No online database currently takes into account all the consequences of these genotypes, a situation compounded by some problematic previous annotations of CDKN2A related sequences and descriptions of their mutations. As an initiative of the international Melanoma Genetics Consortium, we have therefore established a database of germline variants observed in all loci implicated in familial melanoma susceptibility. Such a comprehensive, publicly accessible database is an essential foundation for research on melanoma susceptibility and its clinical application. Our database serves two types of data as defined by HUGO. The core dataset includes the nucleotide variants on the genomic and transcript levels, amino acid variants, and citation. The ancillary dataset includes keyword description of events at the transcription and translation levels and epidemiological data. The application that handles users' queries was designed in the model,view. controller architecture and was implemented in Java. The object-relational database schema was deduced using functional dependency analysis. We hereby present our first functional prototype of eMelanoBase. The service is accessible via the URL www.wmi.usyd.e, du.au:8080/melanoma.html.

Rates of electronic energy transfer in conformationally flexible bichromophoric macrocyclic complexes: a combined experimental and molecular modeling study

Electronic energy transfer (EET) rate constants between a naphthalene donor and anthracene acceptor in [ZnL4a](ClO4)(2) and [ZnL4b](ClO4)(2) were determined by time-resolved fluorescence where L-4a and L-4b are the trans and cis isomers of 6-((anthracen-9-yl-methyl)amino)-6,13-dimethyl-13-((naphthalen-1-yl-methyl)amino)-1,4,8,11-tetraazacyclotetradecane, respectively. These isomers differ in the relative disposition of the appended chromophores with respect to the macrocyclic plane. The trans isomer has an energy transfer rate constant (k(EET)) of 8.7 x 10(8) s(-1), whereas that of the cis isomer is significantly faster (2.3 x 10(9) s(-1)). Molecular modeling was used to determine the likely distribution of conformations in CH3CN solution for these complexes in an attempt to identify any distance or orientation dependency that may account for the differing rate constants observed. The calculated conformational distributions together with analysis by H-1 NMR for the [ZnL4a](2+) trans complex in the common trans-III N-based isomer gave a calculated Forster rate constant close to that observed experimentally. For the [ZnL4b](2+) cis complex, the experimentally determined rate constant may be attributed to a combination of trans-Ill and trans-I N-based isomeric forms of the complex in solution.

As políticas públicas de cultura no Espírito Santo entre 2007 e 2014

Nesta Dissertação os capítulos foram elaborados de maneira a estabelecer inicialmente um panorama da história da política pública ao longo do tempo e sua relação com a cultura, passando pelos conceitos da política pública de cultura, analisando os modelos de políticas culturais e a gestão cultural na democracia. Em seguida foi feito um estudo sobre a política cultural a partir da década de 80, para então analisar a participação das instituições públicas no processo de desenvolvimento após 1988. Diante da nova constituição foi lançado um olhar analítico sobre seus reflexos no campo da cultura desde o neoliberalismo até a segunda década do século XXI, além de uma visão do MinC sobre a arte contemporânea. Só então foram pesquisadas com mais profundidade as políticas públicas de cultura no estado do Espírito Santo, considerando as atuações das instituições públicas no processo de desenvolvimento, proporcionadas pelas aplicações dos Editais e seus desdobramentos, ligados a cada área de atuação dos segmentos culturais que são beneficiários, enfocando ainda as dimensões da cultura e os dilemas e alternativas das políticas públicas culturais com relação aos excluídos. A partir daí foi feita uma abordagem dos diversos segmentos artísticos do estado, suas atuações e suas carências, tendo como ponto de apoio os Editais. Foi analisado o Plano estadual de Cultura no contexto de sua relação com os segmentos culturais, considerando sua concepção original e o estado atual. Foram ainda analisadas as implicações das ações transversais entre os diversos órgãos governamentais e a cultura tendo em vista a equalização de Políticas Públicas de Cultura para o estado.

Distribuição espacial de atributos de solo e de plantas na cultura do mamoeiro no norte capixaba

No Brasil, as lavouras de mamoeiro das planícies dos tabuleiros costeiros são as que melhor desenvolvem e aplicam tecnologias para a produção de mamão no mundo. O objetivo foi aplicar a estatística clássica e a geoestatística no mapeamento e na correlação da variabilidade espacial de atributos químicos e físicos de solo e de plantas de mamoeiro (Carica papaya L.) de uma lavoura comercial do norte capixaba cultivada em um Argissolo típico dos tabuleiros costeiros. O solo de textura arenosa de caráter coeso foi preparado convencionalmente e cultivado com mamoeiro variedade Golden THB. Após a sexagem, procederam-se as amostragens de solo, amostrado na projeção da copa (0-0,20 e 0,20-0,40 m) para a determinação dos atributos químicos e físicos, e de atributos biométricos das plantas em uma área de 1,2 ha (114 x 110 m) totalizando 129 pontos amostrais georreferenciados. Ao nono mês após o transplantio, registrou-se a altura da colheita dos primeiros frutos, o número e a massa dos frutos colhidos para estimativa da produtividade, amostrando três plantas por ponto amostral durante três meses. Os dados foram submetidos à análise estatística descritiva e à correlação de Pearson. A dependência espacial das variáveis foi analisada através da ferramenta geoestatística, com obtenção de semivariograma e os mapas de distribuição das variáveis. A maior parte dos atributos de solo e de plantas de mamoeiro apresenta dependência espacial e é mapeada adequadamente. Há correlação de dependência vertical para densidade do solo, argila, silte, resistência do solo à penetração na linha de plantio e na rua e volume total de poros. Dos atributos químicos não ocorre este comportamento apenas para K, Al e Sat K. As frações areia e argila foram os principais atributos a constituírem correlação com os demais. Há poucas correlações dos atributos do solo com os atributos biométricos e a produtividade do mamoeiro. Ocorre correlação positiva entre a produtividade inicial do mamoeiro com características biométricas ideias para as plantas de mamoeiro. A fertilidade e o preparo do solo são expressivos para o desenvolvimento do mamoeiro e para a variabilidade espacial dos atributos avaliados.

Potássio : fontes alternativas, tratamentos térmicos e disponibilidade para plantas de milho (Zea Mays L.)

Nosso país é um dos principais produtores agrícolas do mundo e altamente dependente da importação de fertilizantes, principalmente o potássio. Visando reduzir essa dependência, materiais provenientes de rochas para fornecimento desse elemento estão sendo testados. Este estudo foi divido em dois experimentos: um experimento em laboratório e um em casa de vegetação. O experimento em laboratório teve por objetivo avaliar os diferentes tipos de tratamentos térmicos e extratores, associados a fontes alternativas de potássio, no aumento da disponibilidade de K. O ensaio foi realizado num delineamento experimental inteiramente casualizado num esquema fatorial 4 x 5 x 3, com quatro repetições. Os fatores estudados foram: quatro fontes alternativas de potássio (verdete, fonolito, gnaisse e granito); cinco tratamentos térmicos (radiação em forno micro-ondas; autoclavagem; aquecimento em forno mufla com resfriamento rápido; aquecimento em forno mufla com resfriamento lento; e o material in natura); e três extratores: água, ácido cítrico 2 % e solução Mehlich-1. As extrações foram realizadas utilizando 4 g das fontes alternativas, adicionando-se 40 mL de cada extrator, as amostras foram agitadas, centrifugadas, filtradas e avolumadas. Foram realizadas seis extrações sucessivas e determinada a concentração de potássio nos extratos. Os dados obtidos foram submetidos à análise de variância, sendo seus efeitos desdobrados em contrastes ortogonais. O experimento em casa de vegetação teve por objetivo avaliar o efeito da utilização de fontes alternativas de potássio, submetidas a tratamentos térmicos, no fornecimento de potássio para plantas de milho (Zea mays L.). O delineamento experimental adotado foi em blocos casualizados, em um esquema fatorial (3 x 5) + 1, sendo três fontes alternativas de K (verdete, fonolito e granito), submetidas à cinco diferentes tratamentos (aquecimento em forno mufla com resfriamento lento, aquecimento em forno mufla com resfriamento rápido, radiação em forno micro-ondas, autoclavagem, e o material in natura). As fontes alternativas foram comparadas com o cloreto KCl. Amostras de solo contendo 2 dm³ de TFSA, foram incubadas durante 20 dias. Após a adubação, em cada vaso foram aplicadas as fontes alternativas de potássio. Realizou-se o plantio com cinco sementes de milho e posterior desbaste, deixando três plantas por vaso. Decorridos 40 dias da semeadura, foi realizado o corte da parte aérea das plantas, a coleta de amostras de solo para análise dos teores de potássio e separação das raízes. Os dados obtidos foram submetidos à análise de variância e desdobrados em contrastes ortogonais. Observando os resultados obtidos nos experimentos de laboratório e casa de vegetação, podemos concluir que a fonte alternativa e proporcionou melhores resultados e que possui potencial agronômico para ser utilizada como fonte alternativa de potássio foi o fonolito. Utilizando o fonolito como fonte alternativa de nutrientes, o tratamento térmico que proporcionou melhores resultados foi o com aquecimento em forno mufla, principalmente quando o resfriamento foi realizado lentamente.

Heterodox Autonomy Doctrine: realism and purposes, and its relevance

The Autonomy Doctrine, elaborated by Juan Carlos Puig, is a realist point of view of International Relations. It is an analysis, from the periphery, about the structure of world power, and a roadmap (from a theoretical point of view) for the longing process of autonomization-regarding hegemonic power-for a country whose ruling class would decide to overcome dependency. The elements its author took into account when analyzing its own context are explained in this text and, afterwards, are reflected over its relevance nowadays. For that purpose, it is necessary to answer certain questions, such as which are the concepts and categories that may explain its relevance, its applicability to regional integration and cooperation models and projects, and what would be the analytical method to compare reality versus ideas, among others. The methodological proposal to analyze the relevance of Puig's doctrine is to compare it to different visions of regionalism that are currently in effect in Latin America.
