Abstract:

This study was designed to establish the prevalence of HLA-B*5701 at HIV-1 infected individuals in Brazil. A total of 517 consecutive individuals were followed in this study from February 2009 through July 2011. The presence of HLA-B*5701 was determined by Nested-PCR with HLA-B*57 and HLA-B*5701 sequence-specific primers (PCR-SSP). The expression of HLA-B*57 was negative in the 385 (74.5%) and positive in the 103 (19.9%) of infected individuals. Among these, the expression of HLA-B5701 was positive in the 29 (5.6%) of individuals. No demographic or ethnic differences were found between HLA-B*57/HLA-B*5701 HIV-1 negative patients, with a prevalence of Caucasians (57.1%) individuals. During the period of study, 68 patients were submited to an abacavir contain- ing regimen. The HLA-B*5701 allele was observed in 7 (10.3%) patients, with a significant incidence of Hypersensitivity reactions at 4 of them (p < 0.001). Conclusions: Although Brazilian population consists of a mixture of individuals of Caucasian, African and Native American genetic background, prevalence of HLA-B*5701 in this population is similar to the one found in pure Caucasians.


Desova da pescada-foguete, Macrodon ancylodon
Yamaguti, N.;
Boletim do Instituto Oceanográfico , 1967, DOI: 10.1590/S0373-55241967000100009
Abstract: this paper aims at the determination of (1) period and area of spawning, (2) length and age at first spawning and (3) sex ratio of the 'pescada-foguete' (macrodon ancylodon) from the southern coast of brazil. the results obtained show that spawning occurs during october-may with a partial spawning in december and in march-april; the area of spawning was found to be between latitude 32os and longitude 51ow and 52ow. the first maturation occurs when the fish reach 25 cm long, being complete in about six months. the sex ratio found was 48% females for 52% males.
Mortalidade da pescada-foguete, Macrodon ancylodon
Yamaguti, N.;
Boletim do Instituto Oceanográfico , 1968, DOI: 10.1590/S0373-55241968000100005
Abstract: the instantaneous mortality coefficient (f + m) of the commercial weakfish, macrodon ancylodon (bloch, 1801) caught by trawls along southern brazilian coast (from latitude 28os to 34os), was computed by means of the annual catch variation (in number) by age per fishing effort from march 1961 to december 1964. the instantaneous mortality coefficient mean values for female and male was respectivelly 1.31 and 1.53. one year old recruits appear in the landings and the mesh selectivity operates on fish up to three years old. three-year old class predominates in the landings.
Diferencia??o geográfica de Macrodon ancylodon (Bloch & Schneider, 1801) na costa brasileira, entre as latitudes 18o36'S e 32o10'S: etapa I
Yamaguti, Noriyoshi;
Boletim do Instituto Oceanográfico , 1979, DOI: 10.1590/S0373-55241979000100002
Abstract: multiple range tests according to kramer, 1956 were performed on 3 meristic and 15 morphometric characters of "pescada-foguete" (macrodon ancylodon) samples collected off coast near concei??o da barra (espirito santo state), atafona, macaé, ubatuba cities, bom abrigo island and rio grande do sul state coast. it was also observed morphological differences in otoliths collected at each region. the number of statistical differences among samples and different morphological characteristics presented by otoliths suggested the existence of four populations along the studied area: (1) along espírito santo state coast; (2) near the region between atafona and macaé coasts; (3) along s?o paulo, paraná and north santa catarina states coasts and (4) along rio grande do sul state coast. probably the differentiation was caused by different environmental conditions observed among regions. other papers about life history corroborate these results except for the espírito santo population about which there is no biological information up to the moment.

The Role of Maternalism in Contemporary Paid Domestic Work  [PDF]
Amanda Moras
Sociology Mind (SM) , 2013, DOI: 10.4236/sm.2013.33033
Abstract:

Various studies of domestic work have identified close personal relationships between domestic workers and employers as a key instrument in the exploitation of domestic workers, allowing employers to solicit unpaid services as well as a sense of superiority (Rollins, 1985; Romero, 2002; Glenn, 1992; Hondagneu-Sotelo, 2001). Likewise, other scholars have pointed out that close employee-employer relationships may actually empower domestic workers, increasing job leverage (Thorton-Dill, 1994). Ultimately, these lines are blurry and ever changing as employers continuously redefine employee expectations. Drawing from a larger study involving thirty interviews with white upper middle class women who currently employ domestic workers (mostly housecleaners) this paper explores employers’ interactions with domestic workers. Through these interviews this research elaborates on how employers and employees interact, how employers feel about these interactions, and explores to what extent these interactions are informed by the widely reported maternalistic tendencies of the past, while also considering the consequences of this.

Epistemological Limits to Scientific Prediction: The Problem of Uncertainty  [PDF]
Amanda Guillan
Open Journal of Philosophy (OJPP) , 2014, DOI: 10.4236/ojpp.2014.44053
Abstract: A key issue regarding the reliability of scientific prediction is uncertainty, which also affects its possibility as scientific knowledge. Thus, uncertainty is directly related to the epistemological limits of prediction in science. Within this context, this paper considers the obstacles to scientific predictions that are related to uncertainty. The analysis is made according to the twofold character of the limits of science, which is characterized in terms of the “barriers” and the “confines.” In addition, the study takes into account the presence of internal and external factors related to the epistemological limits of science. Following these lines of research, the analysis is focused on two steps. First, there is a characterization of the coordinates of Nicholas Rescher’s approach, which is particularly important regarding the epistemological limits to scientific prediction. Second, there is a study of uncertainty as an epistemological obstacle to predictability. Thereafter, the consequences for the future are pointed out.
Artful Deception, Languaging, and Learning—The Brain on Seeing Itself  [PDF]
Amanda Preston
Open Journal of Philosophy (OJPP) , 2015, DOI: 10.4236/ojpp.2015.57049
Abstract:

Despite having named ourselves Homo sapiens—a designation contingent on word/reason (logos) as our chosen identifier—recent evidence suggests language is only a small fraction of the story. Human beings would be more aptly named Homo videns—seeing man—if percentage of cortex area per modality determined the labeling of an organism. Instead, the sentential ontology of language philosophers and linguists persists in spite of the growing body of cognitive research challenging the language instinct as our most defining characteristic. What is becoming clearer is that language is palimpsestic. It is like a marked transparency over visuospatial maps, which are wired to sensorimotor maps. The left lateralized interpreter uses language to communicably narrativize an apparent unity, but people are not the only fictionalizing animals. This examination looks to cognitive and psychological studies to suggest that a prelinguistic instinct to make sense of unrelated information is a biological consequence of intersections among pattern matching, symbolic thinking, aesthetics, and emotive tagging, which is accessible by language, but not a product thereof. Language, rather, is just an outer surface. Rather than thinking man, playing man, or tool-making man, we would be better described as storytelling animals (narrativism). Like other social mammals, we run simulation heuristics to predict causal chains, object/event frequency, value association, and problem solving. The post hoc product is episodic fiction. Language merely serves to magnify what Friederich Nietzsche is rightfully identified as an art of dissimulation—lying. In short, the moral of the story is that we are making it all up as we go along.

Análise da pesca da pescada-foguete na costa centro-sul do Brasil
Yamaguti, N.;Moraes, A. E. D. de;
Boletim do Instituto Oceanográfico , 1965, DOI: 10.1590/S0373-55241965000100005
Abstract: in this paper data on catch and effort by gear are analysed, for weakfish (macrodon ancylodon) landed at santos from january 1959 to december 1963. the region studied was a narrow band about 30 nautical miles wide, along the southern coast of brazil, between 23o s and 34o s. from the analysis of monthly data of production per unit-effort by squares of 1o on a side, we divided the studied region in two areas: area i (from 23o s to 27o s) and area ii (from 28o s to 34o s). the index of unit-effort production and the effort concentration index were computed grouping the data by quarters. from the results we may drow the following conclusions: 1 - in a general way, the effort for catch weak-fish has been applied satisfactorily because the medium and large parejas have operated almost in areas with average density on1 higher than average density; 2 - the production per unit-effort in the area i is smaller than the production in area ii, which suggests that the index of abundance is higher in area ii; 3 - the decrease in production per unit-effort, in area ii, suggests a decrease in the abundance or availability of weak-fish in this area; 4 - in the area i, the index of production per unit-effort remained approximately at the same level.
Crescimento da pescada-foguete (Macrodon ancylodon): aspecto quantitativo
Yamaguti, N.;Santos, E. P. Dos;
Boletim do Instituto Oceanográfico , 1966, DOI: 10.1590/S0373-55241966000100010
Abstract: we determined the age of the commercial marine fish "pescada-foguete" (macrodon ancylodon, bloch 1801) caught by trawls along the southern coast of brazil (28os-34os), from 1961 to 1963, by means of the annuli in otoliths (chugunova, 1959). we correlated the mean total length (l) in centimetres with the age (t) in years by means of the bertalanffy expression adjusted by ford-walford method (beverton & holt, 1957). the mean total length was correlated with the mean weight (w) in grams, by means of the expression w = alb adjusted by least square method, after a logarithmic transformation. results:
