Abstract: this article identifies how different government instruments are used in the implementation of the national policy for museums and how they relate to the governmental goal of democratizing access. the first part defines the term government instruments, exposing its theoretical framework. the national policy for museums is described and its instruments are identified. the second part explains the methodology used for a comparative analysis, and describes the selected variables: incentives, autonomy, information, and complexity. the third part develops the comparative analysis of three instruments: direct management, tax waver, and financial assistance. the results suggest that the instrument financial assistance has a better ability to democratize access. the conclusion suggests proposals to be tested in future research: the tax waiver instrument, being based on the market, strengths the market concentration; direct management has limited effects, circumscribed to places where there is the presence of the state, with limited power to de-concentrate; and financial assistance instrument is the best instrument to democratize opportunities to access museums.

Abstract: Resumo ----- Este artigo identifica como diferentes instrumentos governamentais s o utilizados na implementa o da Política Nacional de Museus e como se relacionam com o objetivo governamental de democratiza o do acesso. Os resultados sugerem que o instrumento de assistência financeira apresenta maior capacidade de democratiza o do acesso, bem como trazem proposi es a serem testadas em pesquisas futuras: o instrumento renúncia fiscal, por ser baseado no mercado, refor a a concentra o do mercado; o instrumento gest o direta tem seus efeitos limitados aos locais onde há presen a do Estado, portanto com limitado poder de desconcentra o; e o instrumento assistência financeira é o que apresenta indícios de poder melhor democratizar as oportunidades de acesso. ----- Government Instruments in the Implementation of the National Policy for Museums ----- Abstract ----- This article identi es how different government instruments are used in the implementation of the National Policy for Museums and how they relate to the governmental goal of democratizing access.

Instrumentos governamentais: reflex es para uma agenda de pesquisas sobre implementa o de políticas públicas no Brasil Governmental instruments: reflections for a research agenda on implementation of public policies in Brazil
Leila Giandoni Ollaik,Janann Joslin Medeiros
Revista de Administra??o Pública , 2011, DOI: 10.1590/s0034-76122011000600015
Abstract: Na administra o pública federal brasileira coexistem instrumentos tradicionais - como implementa o por gest o direta e por uso de incentivos econ micos; por gest o indireta, mediante convênios, concess es de uso - e instrumentos mais recentes. Neste artigo, reflete-se sobre o uso de instrumentos governamentais na implementa o de políticas públicas e se prop e uma agenda de pesquisas no Brasil. A reflex o se justifica pelo interesse em colocar o debate - perene, de teor geralmente ideológico, sobre a relativa superioridade ou n o da gest o direta e da gest o por instrumentos mais indiretos - em base tecnicamente fundamentada. Define-se instrumento governamental como um método identificável por meio do qual a a o coletiva é estruturada para lidar com um problema público. Após levantamento de teorias pertinentes sobre implementa o de políticas públicas e sobre instrumentos governamentais, apresenta-se uma discuss o sobre os possíveis processos de escolha e diversas tipologias existentes. Evidencia-se a necessidade de mais estudos, especialmente brasileiros, na área; sendo recomendada uma agenda com quatro linhas de pesquisa. A variety of government tools or instruments for implementation of public policy coexist at present in the Brazilian federal government, ranging from direct management by government organs to more indirect ones such as economic incentives, grants, and concessions of various sorts. In this essay, we reflect on the use of government instruments in the implementation process and propose a research agenda on the subject for Brazil. This reflection is justified in view of the interest in establishing a solid technical basis for the perennial, and frequently ideological debate about the relative superiority of direct management or management by means of more indirect instruments. Government instrument is defined as being an identifiable method for structuring collective action for dealing with a public problem. After an overview of pertinent theory with respect to public policy implementation and government instruments, a discussion is presented about possible processes for instrument choice and of the variety of existing typologies. The need for further studies, particularly in the Brazilian context, is shown; and a research agenda is recommended.
Concep??es de validade em pesquisas qualitativas
Ollaik, Leila Giandoni;Ziller, Henrique Moraes;
Educa??o e Pesquisa , 2012, DOI: 10.1590/S1517-97022012005000002
Abstract: this essay has as its objective to present the different existing conceptions on validity and on the various ways to assess it, discussing these issues within the scope of qualitative research. the methodology employs the comparative analysis. it was observed that the conceptions of validity can be grouped in three major blocks: conceptions related to the stage of formulation of the study (prior validity), conceptions related to the stage of development of the research (internal validity), and conceptions related to this stage of the results of the study (external validity). it could be noted in each of these stages the presence both of authors with a quantitative perspective and of those with a qualitative view, although their approaches are distinct. the conceptions of validity close to the positivist origins are more concerned with the validity in the formulation and in the results, whereas the more interpretivist conceptions of validity give more emphasis to the development of the research, without, however, disregarding the concern with formulation and results. it can be concluded that a qualitative researcher can and should concern him/herself with the validity of the three stages of the study: formulation, development and results. the validity in qualitative studies seems, therefore, to be wider and more detailed, albeit less quantitatively measurable.
Conversion of ethanol to acetone & other produces using nano-sensor SnO2(110): Ab initio DFT  [PDF]
Leila Mahdavian
Natural Science (NS) , 2011, DOI: 10.4236/ns.2011.36065
Abstract: The material considered in this study, SnO2 (110), has a widespread use as gas sensor and oxygen vacancies are known to act as active catalytic sites for the adsorption of small mo-lecules. In the following calculations crystal line SnO2 nano-crystal have been considered. The grains lattice, which has the rutile structure of the bulk material, includes oxygen vacancies and depositing a gaseous molecule, either ethanol, above an atom on the grain surface, generates the adsorbed system. The conduc-tance has a functional relationship with the structure and the distance molecule of the na-no- crystal and its dependence on these quanti-ties parallels the one of the binding energy. The calculations have quantum mechanical detail and are based on a semi-empirical (MNDO me-thod), which is applied to the evaluation of both the electronic structure and of the conductance. We study the structural, total energy, thermo-dynamic and conductive properties of absorp-tion C2H5OH on nano-crystal, which convert to acetaldehyde and acetone.

Abstract: fish is an important source of heavy metal exposition and contamination for human being. accumulation of mercury (hg) in men occurs by chronicle exposition, through the food chain, by ingestion of fish contaminated with mercury. because of biomagnifications the carnivorous fish that is on the top of the food chain shows a higher concentration of mercury in their tissues and can represent the aquatic environmental contamination. this work aims to establish histopathologic analysis and total mercury concentration in different tissues from thirty-one trichiurus lepturus, a commercial fish from itaipu beach, niterói, rj. t. lepturus collected showed mean values of total mercury concentration of 0.051±0.031μ g g-1 and 0.006±0.004μ g g-1, respectively in muscle and kidney tissues. it was also conducted an analysis of mercury concentration from a pool of brain tissue from all individuals (0.019μ g g-1). minimum and maximum mercury values in muscular and kidney tissues showed a wide dispersion. there was a positive correlation between total length and mercury muscular tissue concentration (r=0.85) and between body weight and mercury muscular tissue concentration (r=0.88), both highly significant. no significant correlation (r=0.24) was observed between kidney weight and mercury tissue concentration (p>0.19). in a multiple comparison test among muscle, kidneys and brain mercury tissue concentration, it was observed a highly significant difference between muscle and kidneys (p<0.001), as well as between muscle and brain (p<0.001). comparison between kidney and brain mercury tissue concentration also showed a significant difference with a probability level of 5% (p<0.05). histopathology demonstrated damage in the kidneys (cartilaginous metaplasia in some individuals and a high presence of melanomacrophage centers).

Revista da Sociedade Brasileira de Medicina Tropical , 2003, DOI: 10.1590/S0037-86822003000500004
Abstract: the aim of our investigation was to evaluate, with a prevalence study, the modes of transmission of hepatitis b virus (hbv), within infected subjects and their household contacts in the state of amazon, western brazilian amazon. we studied 97 index cases and 258 household contacts. out of the 258 household contacts of hbv, 51.6% had serological markers of a past infection, 12.0% signs of active infection, suggesting that the virus circulates within household members. the high prevalence among siblings (23.6%) demonstrates the importance of personal contact in the transmission of this virus. another indirect indicator of intra-familial transmission was the high prevalence of hbv markers within contacts of a fulminant hepatitis. the vertical transmission of hbv in our region may or may not occur, but if it does it as a rare event. our results demonstrate the importance of the presence of hbv, and demand other investigations to clarify the inter-familial transmission of these viruses in our region.
The Impact of First Language Intonational Clue Selection on Second Language Comprehension  [PDF]
Leila Barati, Reza Biria
Open Journal of Modern Linguistics (OJML) , 2011, DOI: 10.4236/ojml.2011.12005
Abstract: Comprehension is closely related not only to the knowledge of words and syntax, but also the pragmatic concerns of the discourse. The purpose of the present study was to investigate the impact of the intonational clues selection of Iranian teenagers' and young adults’ Persian listening comprehension ability on their English learning as a second language. According to Buck (2003), in listening comprehension the input in the form of sounds and intonational clues often conveys additional information. In this study 60 male and female teenagers (13 - 19) and 60 male and female young adults (20 - 26) were selected randomly based on Oxford Placement Test (OPT). Each group was randomly assigned to two sub groups; namely, experimental (EX) and control groups (CG), 15 participants in each group. During the study two fiction and non-fiction passages, at first in Persian and then in English, were read to participants. The passages for participants in CG were read without applying speaker’s intonation changes but they were read for participants in EX with applying speaker’s intonation changes. In this study factors as age and gender are important because the results showed that the difference between two groups with different age ranges was significant, and participants’ inferencing, correct clue selection and listening comprehension ability in the experimental group was superior to the control group in the first language (Persian) and it also influenced positively second language learning and inferencing ability (English).
